The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *Note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options.

The IPv6 address used for the connection will be matched against +the DHCPv6/static IPv6 address, the RA (router advertise) address, and the +assigned link local address. + +VLAN support: + +VLAN support is only supported when using static IP addresses. +Also, currently only 1 VLAN is supported per physical network interface. +Either non-VLAN offloaded traffic is allowed or VLAN offloaded traffic +is allowed. The current implementation does not support both at the +same time. + +Currently there is no explicit VLAN attributes in the iface file. +To configure the VLAN offload, the iface.hwaddress attribute or +physical net_ifacename (without the VLAN identifier) must be used +to specify the HBA device. For the proper CNIC routing, the +corresponding L2 interface which has the associated VLAN interface must +have an IP address on the same subnet. + +The following attributes need to be filled when offloading via the +VLAN interface: + + iface.iscsi_ifacename = + iface.hwaddress = XX:XX:XX:XX:XX:XX + iface.ipaddress = XX.XX.XX.XX + iface.transport_name = bnx2i + +Setting IP address: + +On RHEL5.4, RHEL5.5+, RHEL6.0+, and SLES11SP1 distributions, +discovery login is done over the Linux TCP/IP stack and L2 network +interface. The ethx interface corresponding to the HBA must +therefore be in the same IP subnet in order to reach the iSCSI +target during discovery. However, the HBA's IP address should not +be the same as the L2 ethx's IP address. + +Starting with RHEL6.1 and all other newer distributions, discovery +using SendTargets is done over the HBA interface, so there is no +need for the HBA and L2 network to be on the same subnet. However, +if VLAN is used on the HBA, they still have to be on the same subnet +as described above. + + +Setting Netmask and Gateway addresses: + +With the current limitations of the iface file, there are no entries +to allow the user to enter a netmask or gateway IP address. + +The only way to explicitly configure these options is to use DHCP +addressing. Then the netmask/gateway are set on the DHCP server. +These settings are then sent to uIP via the DHCPOFFERs. + +If the netmask is not defined then the netmask are automatically +generated depending on the destination IP address. + +Debugging: +======================================= + +By default, the iscsiuio daemon does not output any messages to the log file, +'/var/log/iscsiuio.log'.

Problem: Cont00054996 - Multi-session, multi-protocol mtu stress + does not recover all sessions + Cause: Segfaults were observed caused by the accessing of the IPv6 + NDP structure while the nic is undergoing a reset either + due to a DHCPv4 request from iscsid or the handling of + if_down due to the NL handler from CNIC. + Change: The fix involves the following: + - Fixed the handling of staggered IPv4/v6 DHCP/static requests + - Fixed memory leak due to reallocation of IPv4 and IPv6 + DHCP structs + - Fixed the pthread join stuck problem in the handling + of the if_down NL message + + 5. Problem: Cont00054810 - Linux NMI - bnx2x_init_hw_common:PXP2 CFG + failed running iSCSI MTU stress test + Cause: This only happens in DHCPv4 mode. The problem was caused + by contention between the elongated window of performing + DHCP in the enable_nic thread while receiving the asynchronous + if_down NL message (from the MTU change event) from the + CNIC NL thread. The problem occurs when the enable_nic + thread tries to call bnx2x_open while the other thread + calls the bnx2x_close routine. + Change: Fixed mutex lock bugs for the enable_nic thread. Also + extended the nic_disable timeout to 10s to compensate for + the DHCP operation. + + 6. Problem: Cont00054818 - RH6.0 - Unable to logout of iSCSI session + after running PQA baseline scripts + Cause: This was caused by the call to cancel the enable_nic + thread when disabling the nic but failed to unlock the + nic mutex that the enable_nic thread held. + Change: Wake up the enable_nic thread and wait for it to complete + instead of canceling it in the nic_disable path. + + 7. Problem: Cont00054725 - Previous static HBA IP will be used after + a new static HBA IP has been created + Cause: There was an assumption in the code where if the same + nic_iface structure was found based on the nic/vlan pair, + the specified IP address would not be used. Instead, it + will continue to use the previous defined IP address. + Change: The previous IP address will now be compared against the + the specified IP address before finishing the parce + iface request from iscsid. If different, the current + nic will be disabled and then re-enabled with the newly + specified IP address. + + 8. Problem: Cont00054571 - Unable to connect to routed ipv6 target + with RA address and iface DHCPv6 + Cause: The default router address was not being employed for + the IPv6 neighbor negotiation. Additionally, the return + address of our neighbor advertisement was incorrect as + it should use the best matched src address instead. + Change: Fixed both the IPv6 neighbor solicitation and advertisement + transmission and handling. + + 9. Problem: Cont00054510 - fails to login to 32 session with blanket + login IPv6 + Cause: A bug was introduced in uIP 0.6.4.6 where the NIC_RUNNING + flag might not be set when entering the main loop under + certain situations depending on the nic bring up. + Change: A new NIC_STARTED_RUNNING flag is now defined to fix CQ53511. + + 10. Problem: Cont00053807 - RA and link local are unable to connect if DHCPv6 + fails + Cause: The host link local address was not being searched as one of + the host address to be replied to CNIC for the connect request. + Change: The path reply now includes the search of host link local + address as well. + + 11. Problem: Cont00054236 - iSCSI service must be restarted before an IPv6 + connection can be made to the Equalogic target + Cause: The problem was intermittent as it depends on which IPv6 address + the target was redirecting to. Since uIP was only extracting + the target's IPv6 address + MAC from the target's neighbor + advertisement packet itself and not from the ICMPv6 option, so + the wrong or no MAC address will get send down to CNIC for the + connection establishment; hence the no connect. + Change: Added the updating of the neighbor discovery table to also use + the Target IPv6 address + MAC specified in the incoming neighbor + advertisement's ICMPv6 option field. + + 12. Problem: Cont00053255 - bnx2x panic dump logging into multiple + discovered IPv6 nodes (Equalogic IPv6 target) + Cause: The bnx2x panic was fixed in the 10g fw 6.4.29. + A IPv6 connectivity issue was then found and led to different + kernel/uIP crashes. This was caused by the same IPv6 + connectivity problem mentioned above. + Change: Same as above + + 13. Problem: Cont00053728 - Sessions never recover after doing initiator-side + cable pull test with IPv6 traffic against Equalogic targets + Cause: It was discovered that the Equalogic would send out periodic + neighbor solicitation to maintain the connection to the + initiator. Since uIP was responding with the assigned IPv6 + link local address in the neighbor advertisement + unconditionally, the target was observed to stop transmitting on + the connection specified. + Change: The neighbor advertisement generated will now use the dst IPv6 + address from the input neighbor solicitation packet instead of + the assigned IPv6 link local address for both the packet and the + ICMPv6 source IPv6 address. + + 14. Problem: Compile error under 32-bit OS + Cause: A bug was introduced in the previous release 0.6.4.6 which + caused a compilation error in 32-bit OS (64-bit compiles + fine) + Change: Fixed the bug + + 15. Problem: Cont00053807 - RA and Link local are unable to connect if dhcpv6 + fails + Cause: There was a bug in the nl reply where the RA address will never + be sent back to CNIC for the connection request + Change: The best matched address to the dst will now be sent back to + CNIC in the path rsp. + + Enhancements + ------------ + 1. Change: Updated README to remove the 57713/E references + + 2. Change: Allow the ICMP option field in the IPv6 Neighbor Advertisement + response to be included without discrimination. This fixes + an issue connecting against the EQL via RA for DHCPv6. + + 3. Change: Updated README for the IPv6 operation, VLAN, and discovery. + + +uIP v0.7.0.1 (Mar. 29, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00053511 - bnx2x panic dump during ifup/down stress with + iSCSI traffic + Cause: The panic dump was resolved by the driver's rq dbell size fix. + After that, uIP crashed due to the asynchronous if_down event + that took the chip resources away while the nic thread is still + continuing to try to send DHCP request. + Change: Added synchronization between the two threads so proper clean up + of the threads can occur. + + Enhancements + ------------ + 1. Change: Added support for E3 (57800, 57810, and 57840) + + +uIP v0.6.4.5 (Mar. 23, 2011) +======================================================= + Enhancements + ------------ + 1. Change: Optimized the double VLAN fix of CQ53870 to match + what will be submitted for RHELS5.7 and RHELS6.1 inbox + + +uIP v0.6.4.4 (Mar. 17, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00053870 - Unable to login to iSCSI target via offload + through a Nexus 5020 switch with DCBx enabled + Cause: Double VLAN tagging was observed due to DCBx enabled. + The chip actually adds a VLAN tag if the txbd does not have + VLAN tag enabled under the DCBx environment for PRI setting. + Since uIP does not make use of hw assisted VLAN tagging, + 2 VLAN tag was observed in the data stream. + Change: Enabled hw assisted VLAN tagging in uIP for both 1g and 10g. + + 2. Problem: Cont00053792 - maxconnections intermittently fail and + recover using iface DHCPv4 + Cause: The DHCPv4 engine erroneously keeps on requesting for a + new lease which tremendously hamper normal path_req + operation. The problem is that the lease time parameter + has overflowed when converted to ticks count. + Change: Expanded the lease timer ticks count parameter from 16 to + 32 bits. + + 3. Problem: Cont00053807 - RA and link local are unable to connect if + DHCPv6 fails + Cause: The DHCPv6 engine does not have the failover to use RA + mechanism + Change: Expanded to use best match address instead regardless of + DHCPv6 success or not, or using static v6. + + Enhancements + ------------ + 1. Change: Cont00051823 - Added man page for brcm_iscsiuio + + +uIP v0.6.4.3 (Mar. 15, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00053719 - intermittent logging into targets that + are not in the same subnet as defined in the iface + Cause: The default route was used erroneously due to a miscompare + Change: Fixed this comparison so if the requested dst is not in + in the same subnet, uIP would not even ARP out. + + 2. Problem: Cont00053580 - Unable to do iSCSI boot into Linux OS using + 57710 adapters + Cause: The E1 iro USTORM_RX_PROD_OFFSET doesn't match the t6.4 fw + Change: This is now fixed + + +uIP v0.6.4.2 (Feb. 24, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00050343 - HBA does not follow RFC2131 spec for IPv4 + DHCP lease expiration + Cause: The dhcp engine did not have this feature implemented + Change: Added lease time tracking and renewal + + 2. Problem: Cont00050801 - Unable to connect to target after switching + between DHCPv4 to static v4 + Cause: The configuration flags got corrupted when switching between + dhcp and static or vice versa. + Change: Fixed the flag handling. Also needed to zero out the static + ip address in the host memory when switching to dhcp. + Otherwise, the static ip address will get used mistakenly. + + Enhancements + ------------ + 1. Change: Cont00051936 - Added IPv6 NDP and DHCPv6 support. + + +uIP v0.6.4.1 (Jan. 27, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00049766 - segfault seen while stopping iscsi service + Cause: The logger output routine was accessing the log resource + while another thread calls fini_logger to free the same + resources + Change: Added pthread mutex lock to the logger routine to exclude + the initializer, user, and finisher + + Enhancements + ------------ + 1. Change: Added new t6.4 HSI and 57713 support. + + +uIP v0.6.2.13 (Jan. 04, 2011) +======================================================= + Fixes + ----- + 1. Problem: Cont00049665 - iscsiboot:linux failed to boot into iscsi + boot image in offload path after 5 iterations + Cause: The hw consumer index for the uIP ring got out of sync + with the producer index. This has led to the xmit mutex + lock be held forever so subsequent ARP requests will not + get transmitted to the wire + Change: Added this out of sync detection and rescue the xmit mutex + lock + +uIP v0.6.2.12 (Dec. 21, 2010) +======================================================= + Fixes + ----- + 1. Problem: Cont00051820 - Session fails to reconnect after gateway + fallback + Cause: Under the HSRP test scenario, it was found that an ARP + request from the SUT is required in order for the HSRP + router to begin sending packets downstream to the SUT. + The default ARP age was originally set to 20 minutes + before a new ARP request will get sent, + Change: Changed the ARP age default to Linux default at 5 minutes + +uIP v0.6.2.11 (Dec. 17, 2010) +======================================================= + Fixes + ----- + 1. Problem: For IPv4, the gateway route was not being utilized + when the subnet mask given or calculated does not + match. This resulted in many unwanted connection + attempts. + Cause: A bug was found in the default gateway calculation + logic which prevented the gateway address from being + used. + Change: Fixed the default gateway logic + + 2. Problem: For IPv6, there are scenarios where it won't connect + Cause: The IPv6 subnet mask as extracted from the CIDR + format might contain garbage data. This garbage data + was then used as part of the subnet mask which would + prevent the correct address mask. + Change: Fixed the subnet mask + +uIP v0.6.2.10 (Dec. 15, 2010) +======================================================= + Fixes + ----- + 1. Problem: IPv6 does not connect for non-CIDR iface.ipaddress + specification + Cause: A bug where all ones was used as the IPv6 netmask + instead of all zeroes. This prevented all IPv6 + path requests from being honored + Change: Fixed the subnet mask used + +uIP v0.6.2.9 (Dec. 14, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Added IP address CIDR notation support for the + iface.ipaddress field in the iface file. + This will allow subnet mask to be defined and used. + +uIP v0.6.2.8 (Dec. 9, 2010) +======================================================= + Fixes + ----- + 1. Problem: ipv6 + ifup/down fails to reconnect + + Cause: There were 2 problems found: + - the xmit_mutex lock was being held indefinitely + - the nl_process_if_down flag for 10g doorbell ringing + did not get reinitialized + + Change: Fixed the xmit_mutex deadlock via trylock + Added nl_process_if_down initialization in the IF_DOWN + process + + 2. Problem: Added fix for the NPAR disabled for 57712 + + Cause: The mac address was not handled correctly + + Change: Fixed the mac address handling. Also requires corresponding + kernel component for the complete fix + +uIP v0.6.2.7 (Dec. 7, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Use the gateway address from the DHCP server the + destination IP address is not in the current subnet. + +uIP v0.6.2.6 (Nov. 16, 2010) +======================================================= + Fixes + ----- + 1. Problem: Warning message seen in the kernel logs, + "uio uio2: uevent: unsupported action string" + + Cause: The improper string was echo'ed into the UIO trigger + field. With an improper string, this message would + appear in the kernel logs. + + Change: uIP will now write the string "online" to the UIO + trigger field. This is the string expected by the + Linux kernel base driver. + + 2. Problem: uIP would segfault during a heavily login/logout + iSCSI subsystem reset senario + + Cause: A double free occurred in the logging portion of the + uIP code, but this was root cause to a double free when + manipulating the NetLink buffers. + + Change: Properly look at the return code from the routine which + will read NetLink messages. Also only free buffers + if they are allocated. + + Enhancements + ------------ + 1. Change: Add ability to print kernel version and machine + architecture to further help debug problems. + + 2. Change: Apply the netmask from DHCP if provided. + +uIP v0.6.2.5 (Nov. 10, 2010) +======================================================= + Fixes + ----- + 1. Problem: iscsid would try to conenct with unintended iSCSI + targets + + Cause: uIP would blindly return the iSCSI target MAC address + regardless if the iSCSI target is reachable via the + given port. + + Change: uIP will try to filter the requests coming from CNIC + by automatically generating a network mask based off + the configured IP addressed. Then this netmask is + masked with the destination IP address. If there is + a match, then the path_req is allowed through. + + 2. Problem: Problems reconnecting back to the target when running + MTU stress tests. + + Cause: cnic/bnx2i and uIP could possibly get out of sync when + an if_down message is sent. + + Change: uIP will now immediately react to the if_down message, + and flush all the path req's and then to process to + if_close. + + Enhancements + ------------ + 1. Change: Fix compile warnings for src/unix/nic_nl.c, + and src/unix/main.c + +uIP v0.6.2.4 (Nov. 4, 2010) +======================================================= + Fixes + ----- + 1. Problem: iSCSI HBA: brcm_iscsiuio segfault during ifdown + with many active sessions + + Cause: uIP will segfault when traversing the error path when + an iSCSI connection is starting but the sysfs entries + have not been created yet. + + Change: Use the errno value rather then the one from the file + descriptor because the file descriptor will be NULL and + the NULL dereference will cause a segfault. + + Enhancements + ------------ + 1. Change: Added initial changes for iSCSI multi-function support for + 10G NIC's. + 2. Change: Add more detailed messages for error pathes in nic_utils + +uIP v0.6.2.3 (October 28, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Add support for bnx2x-1.62.x drivers + +uIP v0.6.2.2 (October 18, 2010) +======================================================= + Enhancements + ------------ + 1. Change: Only allow iSCSI connections with known bnx2x HSI's. + +uIP v0.6.2.1 (October 7, 2010) +======================================================= + Fixes + ----- + 1. Problem: After multiple MTU changes, the ethtool IOCTL used to + determine the bnx2x driver version fails and eventually + iSCSI connections would not reconnect. + + Cause: The socket file descriptor used during the ethtool IOCTL + call was never closed and leaked. + + Change: On the error path when calling the ethtool IOCTL, the + file descriptor is now properly closed. + +uIP v0.5.39 (September 15, 2010) +======================================================= + Fixes + ----- + 1. Problem: Could not offload IPv4 VLAN connection when the target tries + to ARP the iSCSI initiator + + Cause: In the ARP reply, the ether field was incorrect. + + Change: Properly set the ether field to 802.1Q type (0x8100) + +uIP v0.5.38 (September 14, 2010) +======================================================= + Fixes + ----- + 1. Problem: uIP would cause a panic dump when the NIC was going down + + Cause: uIP and CNIC where not synchonized on NIC state + + Change: Check if the RX BD's which are zero'ed by CNIC when the + NIC is going down. If the BD addresses are zero, then + uIP will drop the TX packets. + +uIP v0.5.37 (August 21, 2010) +======================================================= + Fixes + ----- + 1. Problem: uIP would segfault on ifup/ifdown stress test when using + DHCP to determine local IP address. + + Cause: The uIP would use a NULL buffer during data transmission. + + Change: Drop packets when there are no buffer avaliable. + +uIP v0.5.36 (August 21, 2010) +======================================================= + Fixes + ----- + 1. Problem: iSCSI boot would not completely login after the pivot + root operation. + + Cause: The uIP would not properly start the NIC interface. + + Change: uIP should only check the NIC state to determine whether + to start the NIC thread or not. + + 2. Problem: uIP would segfault during if'up if'down testing. + + Cause: The uIP would improperly start 2 NIC threads for the + same NIC interface. + + Change: uIP should properly lock the NIC list when disabling/removing + the NIC threads. + + +uIP v0.5.35 (August 20, 2010) +======================================================= + Fixes + ----- + 1. Problem: Sessions would hang with ethtool self-test + + Cause: The uIP would hang because the socket layer was stuck + because there is much contention for that socket. This + would hang the CNIC thread. + + Change: Remove any IOCTL calls in uIP which may colide with + the ethtool self test. The driver version is only + capture during uIP initialization. + + 2. Problem: There were session recovery issue when using DHCP + if up/down tests. + + Cause: The uIP would hang because the DHCP requests would + timeout if the network interface is downed which would + hang all the other uIP threads. + + Change: Ensure that the DHCP state machine had exit points + if the network interface was down'ed. + + +uIP v0.5.34 (August 18, 2010) +======================================================= + Fixes + ----- + 1. Problem: Sessions would not recover with ethtool self-test + + Cause: The uIP would hang because either the NetLink buffer is + full or that any socket operations used to manipulate + multicast addresses would block. + + Change: Ensure that the socket used for multicast addressing is + set to nonblocking. Drain the NetLink buffer without + using the eventing, but with a more aggressive poll routine. + + 2. Problem: Sessions would not recover with L2 driver load/unload on + RHEL 6.0 SS9 + + Cause: The uIP would close the NIC thread too early and would + deadlock on cloing the NIC thread. + + Change: Ensure that the NIC thread is canceled/closed only in one + location, in the NIC remove routine. + + +uIP v0.5.33 (August 17, 2010) +======================================================= + Fixes + ----- + 1. Problem: Error message seen from the uIP stack for valid packets. + + Cause: The uIP was incorrectly marking logging messages for valid + packets as errors because it didn't know how to parase them. + + Change: Changed the following from error to debug message + ipv6: invalid version + ipv4: invalid version or header length. + icmpv6: unknown ICMP message. + ip: neither tcp nor icmp + Changed the following from error to warn message + udp: bad checksum + tcp: bad checksum + tcp: got reset, aborting connection. + + 2. Problem: After multiple iterations the loading and unloading of + the Broadcom Linux drivers with active connections + would not cause the sessions to recover on RHEL 6.0 + snapshot 9. + + Cause: There was a deadlock in the nic mutex + + Change: Lock ordering for the nic mutex and nic list mutex must + be inforced. + + 3. Problem: After multiple iterations of running the ethtool selftest + the Broadcom Linux drivers with active connections + would not cause the sessions to recover on RHEL 5.5. + + Cause: The Netlink buffer between uIP and CNIC would get full. + + Change: Poll more regularly for packets in the Netlink buffer + from 4 times a second to 100 times a 1 second. + Drain packets during the PATH_REQ packet pull. + + +uIP v0.5.32 (August 14, 2010) +======================================================= + Fixes + ----- + 1. Problem: Error message 'nic eth0: Didn't find type 0xaa bb' seen. + + Cause: Valid non-DIX Ethernet packets as being passed to the + uIP. uIP will drop these packets but should be logged + correctly. + + Change: These packets are valid, and should only be logged for + debugging purposes. + + 2. Problem: Error message 'Dropped previous transmitted packet' seen. + + Cause: The TX ring is full, and here uIP is trying to transmit a + packet which will be dropped. This is a valid state but + the log message is marked incorrectly + + Change: These messages are not warnings and should be logging when + debugging is enabled. + + 3. Problem: Error message: "iscsi_ipc eth0 Transport name is not + equal expected: got: bnx2i" seen. + + Cause: The iface_rec structure is different between iscsid version. + For RHEL 5.5, iscsid is versioned 871, for RHEL 6.0 is + versioned 872. + + Change: Allow uIP to compile against a different version of iscsid. + + +uIP v0.5.31 (August 12, 2010) +======================================================= + Fixes + ----- + 1. Problem: Softlock would occur showing that the NetLink table + lock was taken but never released. + + Cause: NetLink socket buffer would fill with constant PATH_REQ + messages preventing PATH_REQ response from libiscsi + + Change: Now uIP will drain the NetLink buffer while looking for + a response. + + Enhancements + ------------ + 1. Change: Add documentation for VLAN configuration and restrictions. + + +uIP v0.5.30 (August 6, 2010) +======================================================= + Fixes + ----- + 1. Problem: iscsid thread will stall if closing the uio files nodes + is stuck + + Cause: uIP would indefinitely block waiting for the mutex shared + by the close routine. + + Change: Now uIP will try and poll a bit for the mutex. If it can't + get this mutex in the iscsid thread then an error is return + rather then hold the thread. + + 2. Problem: IPv6 Unicast Neighbor Adveriserments would have the + ICMPv6 option header specifying a MAC. + + Cause: uIP should use the source IPv6 address to detmine whether + to strip the option header or not and not the target address + in the ICMPv6 field. + + Change: The uIP stack return a unicast IPv6 Neighbor Advertisement + without the ICMPv6 option as a response to unicast + IPv6 Neighbor Solicitations. + + 3. Problem: There would be TCP SYN packets with improper MAC address. + + Cause: A zero'ed MAC address was not passed to CNIC to indicate an + error or if the IP address didn't resolve. + + Change: The uIP stack will now return a zero'ed MAC address if it + can't find any entries. + + +uIP v0.5.29 (August 6, 2010) +======================================================= + Fixes + ----- + 1. Problem: "uip udp: no matching connection found: lport: 35072" + seen numerous times in the brcm_iscsiuio log file + + Cause: This message was incorrectly marked as an error + + Change: These messages are valid log entries especially if the + packet was a broadcast UDP packet not destined for the SUT + I will change the code to mark these logs entries as debug. + + +uIP v0.5.28 (August 5, 2010) +======================================================= + Fixes + ----- + 1. Problem: Can't login into a redirected Equilogic Target + + Cause: The Equilogic Target uses a unicast IPv6 Neighbor + Solicitation to test if the host is up. The uIP stack + would return a Neighbor Advertisement with an unneeded + ICMPv6 option. + + Change: Only have the uIP stack return a unicast IPv6 Neighbor + Advertisement without the ICMPv6 option. + + 2. Problem: With older bnx2/bnx2x/cnic/bnx2i driver combinations + uIP would segfault when these drivers were unloaded. + + Cause: When the older drivers were removed, the underlying uio + instance was removed causing uIP to have a stale file handle. + When uIP finally closes using this stale file handle, either + uIP would segfault, or there would be an error in the + uio_release() path. + + Change: Only have the uIP close if the UIO file node exists. + + +uIP v0.5.27 (July 31, 2010) +======================================================= + Fixes + ----- + 1. Problem: iSCSI HBA: Unable to use DHCP address for iSCSI interface + if a connection was previously made with a static address + on bnx2 devices. + + Cause: Because the device is closed and reopen'ed the TX consumer + indexes were not persisted + + Change: Only discard the TX consumer indexes only when the devices + will be discarded or closed + + Enhancements + ------------ + 1.

Problem: IPv6 using VLAN's didn't login + + Cause: The uIP code used to determine if the packet was an IPv6 + or not was not working. This VLAN packets for IPv6 were + being mis-interpreted. + + Change: Make the function is_ipv6() VLAN aware + + 3. Problem: Persistant targets was not loggin in during boot + + Cause: If udev was slow and the /dev/uio* were creatly slowly + uIP would fail. + + Change: Poll uIP waiting for /dev/uio* file nodes. + +uIP v0.5.25 (July 27, 2010) +======================================================= + Fixes + ----- + 1. Problem: When using IPv4 DHCP, there are no initial DHCP Discover + packets were not seen on the wire. + + Cause: Packets generated from the app handler from the uIP stack + were not placed on the wire. + + Change: Packets originating from the uIP stack are now always placed + on the wire. + +uIP v0.5.24 (July 25, 2010) +======================================================= + Fixes + ----- + 1. Problem: One would see invalid packet packets flow through the + uIP stack, where the logs would indicate there is a packet + with an invalid length + + Cause: The BD and CQE consumer indexes were not properly incremented + and masked. + + Change: The BD index is now properly masked. The CQE index is not + incremented using the CQE index rather the mistaken BD index. + + Impact: 10G only + + 2. Problem: uIP would segfault during the booting of the machine. + + Cause: uIP was using a NULL data pointer because there was an + incorrect packet passed to the stack. + + Change: Only allow uIP to process data if the packet exists. + + 3. Problem: uIP would stop processing packets + + Cause: The uIP code would not properly drain the CQE ring causing + it to eventually be full + + Change: Consume all the CQE elements even if they are ethernet types + or not. + + Impact: 10G only + + 4. Problem: uIP would stop after if/down of the network interface. + + Cause: uIP was not kick starting the NIC loop thread properly. + + Change: Ensure that the NIC loop thread is started by when iscsid + request that the interface start the offload. Mark the NIC + only if the thread is truly canceled. + + +uIP v0.5.23 (July 20, 2010) +======================================================= + Fixes + ----- + 1. Problem: Segfault during brcm_iscsiuio initialization + + Cause: uIP was using a NULL data pointer, because a different + thread re-initialized the uIP stack + + Change: Properly synchronize the initialization of the stack + + 2. Problem: Deadlock during the printing of heavy debug messages + + Cause: The variable macro structures would point to invalid + data + + Change: With each invocation of va_copy() a corresponding + invocation of va_end() in the same function for the proper + cleanup + + 3. Problem: uIP would hang when the interface could go up/down + + Cause: uIP would get out of sync with the state of the network + interface + + Change: Instead of detriving state from the UIO file nodes, uIP + will take direction from iscsid on when interfaces will be + started. + +uIP v0.5.22 (July 15, 2010) +======================================================= + Fixes + ----- + 1.

It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

A storage node A will only "see" -storage node B, if both are members of the same -discovery domain. -.IP -So if a storage node is registered which is not part of -any discovery domain, it will not see any other nodes. -.IP -By setting -.BR DefaultDiscoveryDomain=1 , -you can tell isnsd to create a virtual "default discovery domain", which -holds all nodes that are not part of any administratively configured -discovery domain. -.IP -By default, there is no default discovery domain. -.TP -.BR RegistrationPeriod -The iSNS server can purge registered entities after a certain period -of inactivity.

The server -will send ESI messages to these portals at regular intervals. -If the portal fails to reply several times in a row, it is -considered dead, and will be removed from the database. -.IP -.B ESIRetries -specifies the maximum number of attempts the server will make -at contacting the portal before pronouncing it dead.

Participants in a message exchange authenticate -messages by adding an "authentication block" containing a time stamp, -a string identifying the key used, and a digital signature of the -message. The same method is also used by SLP, the Service Location -Protocol. -.PP -The string contained in the authentication block is referred to -as the -.IR "Security Policy Index" (SPI). -This string can be used by the server to look up the client's public -key by whatever mechanism; so the string could be used as the name of -a public key file in a directory, or to retrieve an X509 certificate -from LDAP. -.PP -From the perspective of Open-iSNS client applications, there are -only two keys: the client's own (private) key, used to sign the -messages it sends to the server, and the server's public key, -used to verify the signatures of incoming server messages. -.PP -The iSNS server needs, in addition to its own private key, access to all -public keys of clients that will communicate to it. The latter are kept -in what is called a key store. Key stores and their operation will -be discussed in section -.B Key Stores and Policy -below. -.PP -The following configuration options control authentication: -.TP -.BR Security -This enables or disables DSA authentication. -When set to 1, the client will sign all messages, and expect all server -messages to be signed. -.IP -When enabling security in the server, incoming messages are checked -for the presence of an auth block. If none is present, or if the server -cannot find a public key corresponding to the SPI, the message is treated -as originating from an anonymous source. If the SPI is known but the -signature is incorrect, the message is dropped silently. -.IP -Messages from an anonymous source will be assigned a very restrictive -policy that allows database queries only. -.IP -Setting this option to 0 will turn off authentication. -.IP -The default value is -1, which tells iSNS to use authentication -if the required keys are installed, and use unauthenticated iSNS -otherwise. -.TP -.BR AuthName -This is the string that will be used as the SPI in all outgoing -messages that have an auth block.

The file is expected to hold the client's -PEM-encoded public key, and it must use the client's SPI as the name. -This type of key store is not really recommended, as it does not -store any policy information. -.PP -A simple key store can be configured by setting the -.B KeyStore -option to the path name of the directory. -.PP -The recommended approach is to use the database as key store. This -uses vendor-specific policy objects to tie SPI string, public key, -entity name, source name and other bits of policy together, and -store them in a persistent way. -.PP -The database key store is configured by setting the -.B KeyStore -option to the reserved value -.BR DB: , -which is also the default. -.PP -Currently, Open-iSNS policy objects have the following attributes, -besides the SPI: -.TP -Source: -This is the source node name the client must use. It defaults to -the SPI string. -.TP -Functions: -This is a bitmap detailing which functions the client is permitted -to invoke. The bit names correspond to the shorthand names used in -RFC 4711, such as -.BR DevAttrReg , -.BR DevAttrQry , -etc. The default is to allow registration, query and deregistration, -as well as SCNRegister. -.TP -Entity name: -This is the entity name assigned to the client. If set, a registration -by the client is not permitted to use a different entity name. If -the client sends a registration without Entity identifier, the -server will assign the entity name given in the policy. -The default is to not restrict the entity name. -.TP -Object access: -This is a bitfield describing access permissions for each object type. -For each object type, you can grant Read and/or Write permissions. -Read access applies to the Query and GetNext calls; all other operations -require write permission. -The default grants read and write access to objects of type Entity, Storage -Node, Portal and Portal Group; and read access to Discovery Domains. -.TP -Node types: -This bitfield describes which types of storage nodes a client is -allowed to register; the valid bit names are -.BR target ", " initiator " and " control . -The default is to restrict nodes to register initiators only. -.\" ------------------------------------------------------------------ -.SS Network Related Options -.TP -.BR Network.MaxSockets -This is the number of incoming connections accepted, and defaults to -1024.

It defaults to -.BR 60s . -.TP -.BR Network.ReconnectTimeout -When a connection attempt failed, we wait for a short time before we -try connecting again.

The naming and syntax of these attributes as -the same for all commands modes, however certain modes support -only a limited set of attributes. -.PP -Attributes are usually given as -.IB name = value -pairs. Where empty (or NIL) attributes are supported, the -attribute name by itself can be given. -.PP -The syntax of attribute -.I value -depends on the attribute type. For strings and numeric values, -no special conventions apply, but bitfields have a special syntax -described below. -.PP -The attribute name is usually preceded by the object -type it applies to (such as -.BR entity ), -followed by a hyphen and the name itself. However, where the -context clearly determines a specific object type, the prefix -can be omitted. For instance, when editing a policy object -using -.BR \--edit-policy , -it is acceptable to use -.B node-type -as shorthand for -.BR policy-node-type . -.PP -Likewise, in a query command, it is not permitted to mix attributes -from different object types. Thus, the first attribute of a -query string establishes a type context, so that the following -two invocations are equivalent: -.PP -.B isnsadm --query pg-name=iqn.com.foo pg-addr=10.1.1.1 pg-port=860/tcp -.br -.B isnsadm --query pg-name=iqn.com.foo addr=10.1.1.1 port=860/tcp -.PP -.B Isnsadm -currently supports the following attributes: -.PP -.TS -tab(,),box,center; -li|lilili -lt|lbrlb. -Context,Attribute,iSNS tag,Aliases -_ -Network Entity,entity-id,1,eid -\^,entity-prot,2 -\^,entity-index,7 -iSCSI Storage Node,iscsi-name,32 -\^,iscsi-node-type,33 -\^,iscsi-alias,34 -\^,iscsi-idx,36 -\^,iscsi-authmethod,42 -Portal,portal-addr,16 -\^,portal-port,17 -\^,portal-name,18 -\^,portal-esi-port,20 -\^,portal-esi-interval,21 -\^,portal-idx,22 -\^,portal-scn-port,23 -Portal Group,portal-group-index,52 -\^,pg-name,48 -\^,pg-addr,49 -\^,pg-port,50 -\^,pg-tag,51,pgt -\^,pg-idx,52 -Discovery Domain,dd-id,2065 -\^,dd-name,2066 -\^,dd-member-iscsi-idx,2067 -\^,dd-member-name,2068 -\^,dd-member-fc-name,2069, -\^,dd-member-portal-idx,2070, -\^,dd-member-addr,2071, -\^,dd-member-port,2072, -\^,dd-features,2078, -Policy Object,policy-name,-,spi -\^,policy-key,- -\^,policy-entity,- -\^,policy-node-type,- -\^,policy-object-type,- -\^,policy-functions,- -.TE -.PP -.\"--------------------------- -.SS Portal attributes -Portal information is conveyed by two separate attributes -in iSNS; an address attribute holding the IP address, and -a TCP/UDP port attribute holding the port number and an indication -of the protocol to be used (TCP or UDP). -.PP -When parsing a TCP/UDP port, Open-iSNS will expect a port number, -optionally followed by a slash and the protocol.

The names of the bit -values are displayed by built-in help facilities. When specifying -a bitfield attribute on the command line, you can combine them -using the plus (\fB+\fP) or comma (\fB,\fR) character, like this: -.PP -.B node-type=control+initiator -.PP -.\"--------------------------- -.SS Registration mode -Registration mode is selected by using the -.B --register -option, followed by a list of one or more objects -to register with the iSNS server. -By default, this will create a network entity for the -client (if none exists), and place the new objects inside -it. Usually, you register all objects for -a network entity in one operation, rather than each -one separately. -.PP -Each object is specified as a type, optionally followed -by a comma-separated list of attributes, such as -this: -.PP -.B target=iqn.2005-01.org.open-iscsi.foo:disk1,alias=disk1 -.PP -The following object types are currently supported: -.TP -.BI entity= name -Tells the server to group all objects in the specified -Network Entity container object. -Normally, the iSNS server will automatically assign an -entity name that is in line with its policies, and there is -no need to specify it explicitly. -.TP -.BI initiator[= name ] -This will register an iSCSI storage node of type initiator. -By default, the name is set to the iSNS source name. -.IP -This can be followed by any number of iSCSI storage node -attributes. -.TP -.BI target[= name ] -This will register an iSCSI storage node of type target. -By default, the name is set to the iSNS source name. -.IP -This object accepts the same set of attributes as -.BR initiator . -.TP -.BI control[= name ] -This will register an iSCSI storage node of type control. -By default, the name is set to the iSNS source name. -Only management nodes should be registered as control -nodes, as this gives a node complete control over the -iSNS database. -.IP -This object accepts the same set of attributes as -.BR initiator . -.TP -.BI portal=[ address:port/proto ] -This will register a portal using the given address, -port and protocol triple. If the triple is omitted, -.B isnsadm -will use the client host's IP address. If the portal -is preceded by an initiator registration (on the command -line), the port defaults to 860/tcp; if it is preceded by -a target registration, the port defaults to 3260/tcp. -For multi-homed hosts, the choice of address is -implementation dependant. -.IP -This can be followed by any number of portal attributes. -.TP -.B pg -This will register a portal group joining the preceding -portal and node. Portal groups can be used to describe -the preferred portals for a given node; please refer -to RFC 4711 for details. -.IP -This can be followed by any number of portal group attributes. -The attribute list must specify a portal group tag (PGT) -via the -.BR pgt -attribute. -.PP -There are two additional command line options of interest, -which are used exclusively with Registration mode. One is -.BR \--replace . -Normally, registration mode will -.I add -new objects to the network entity associated with the client -host. If you specify -.B \--replace -on the command line, the server will wipe the network -entity completely, and remove all portals and storage -nodes it contained. Then it will create a new network -entity, and place the portals and storage nodes provided -by the caller inside. -.PP -In addition, it is possible to replace just parts of a -network entity. This is achieved by using the command line -option -.B \--key -to specify the object that should be replaced. -.PP -For instance, assume a network entity -contains the portal -.BR 10.1.1.1:860 , -and the client's network address changed to -.BR 10.2.7.7 . -Then the following command will atomically update the -database, replacing just the portal without touching the -registered storage nodes: -.PP -.B " isnsadm --replace --key portal=10.1.1.1:860 portal=10.2.7.7:860 -.PP -The -.B \--key -option recognizes only a subset of the usual attributes: -.RS -.TS -tab(,),box; -li|li -lb|lb. -Object type,Syntax -_ -Entity,eid=\fIidentifier -Portal,portal=\fIaddress\fP:\fPport -iSCSI Node,iscsi-name=\fIname -.TE -.RE -.PP -To get a list of supported attributes, invoke -.BR "isnsadm --register help" . -.\"--------------------------- -.SS Query mode -Query mode is selected by using the -.B --query -option. A query consists of a list of -.BR attr = \fI value -pairs. All attributes must belong to the same object type, -i.e. queries that mix a Network Entity attribute with e.g. -a Portal attribute will be rejected. -.PP -It is also possible to specify an attribute name without -value (i.e. just -.BR attr ), -which will -will match any object that has such an attribute, regardless -of its value. This is useful when you want to query for all -objects of a given type. -.PP -To obtain a list of supported attributes, invoke -.BR "isnsadm --query help" . -.\"--------------------------- -.SS List Mode -In this mode, -.B isnsadm -will display all objects of a given type, optionally -restricted to those matching certain attribute values. -.PP -The arguments to list mode are a -.IR "type name" , -optionally followed by one or more -.IB attr = value -pairs. Only attributes pertaining to the given -type are permitted; for instance, if you specify a -type name of -.BR portals , -only portal attributes are permitted. -.PP -Possible type names are: -.BR entities , -.BR nodes , -.BR portals , -.BR dds , -.BR ddsets , -.BR portal-groups ", and " -.BR policies . -.PP -Additional information is available via -.BR "isnsadm --list help" . -.\"--------------------------- -.SS Deregistration mode -In this mode, you can deregister objects previously registered. -Only the node which registered an entity in the first place is -permitted to remove it, or any of its child objects. (Control -nodes are not bound by this restriction). -.PP -In deregistration mode, the argument list consists of a list of -.IB attr = value -pairs. Deregistration supports the same set of attributes as -query mode. -.\"--------------------------- -.SS Discovery Domain Registration -This mode, allows to register a discovery domain or to add -new members to an existing discovery domain. Again, attributes -are specified as a list of -.IB attr = value -pairs. Only discovery domain attributes are recognized. -.PP -Note, in order to add members to an existing domain, you must -specify the domain's numeric ID. The domain's symbolic name -is not a valid handle when referring to a discovery domain. -.\"--------------------------- -.SS Client Enrollment -This mode only works when the server recognizes the client -as having control node capabilities, which is possible in -two ways: -.TP -Invoke -.B isnsadm \--local -as super user on the host -.B isnsd -is running on. The -.B \--local -options tells it to communicate with the server through -the local control socket. -.TP -Invoke -.BR "isnsadm \--control" , -which tells it to assume the identity of a control node. -When given this option, -.B isnsadm -will use the source name and DSA key specified by the -.BR Control.SourceName " and " Control.AuthKeyFile -configuration options, respectively. -The server must be configured to grant this identity -control node status. -.PP -To enroll a client, use the -.B \--enroll -option, followed by the (source) name of the client to enroll. -This string will be used as the name of the security policy -the client will use to identify itself. -.PP -This is followed by a list of attribute/value pairs, where the -following set of attributes is supported: -.PP -.TS -tab(,),box,center; -li|lilili -lb|lrlb. -Attribute,Description,Aliases -_ -name,Policy Name,spi -key,Client's DSA public key -entity,Assigned Entity Identifier -node-type,Permitted node type(s) -node-name,Permitted node name(s) -functions,Bitmap of permitted functions -object-type,Object access mask -.TE -.PP -The -.B key -attribute is used to specify the DSA -public key that the server should use to authenticate -messages from this client. You can either provide a -file name; in which case -.B isnsadm -will try to read the PEM encoded public key from that file. -If no -.B key -attribute is given, or when using -.BR key=gen ", " isnsadm -will generate a DSA key. The private portion of the newly -generated key will be stored in the file specified by -.BI --keyfile= filename \fR. -.PP -The -.B object-type -attribute is used to specify which object types the client -is permitted to access. This is a comma separated list of -.IB type : perm -pairs, where -.I type -can be any of -.BR entity ", " iscsi-node ", " portal ", " portal-group ", " dd ", " ddset ", and " policy . -The permissions can be either -.BR rw ", or " r . -.PP -The -.B functions -attribute can be used to restrict which functions the client is -permitted to invoke.
