Subject: [PATCH 01/28] url: Added support for parsing login options from the
URL
As well as parsing the username and password from the URL, added support
for parsing the optional options part from the login details, to allow
the following supported URL format:
schema://username:password;options@example.com/path?q=foobar
This will only be used by IMAP, POP3 and SMTP at present but any
protocol that may be given login options in the URL will be able to
add support for them.

Subject: [PATCH 05/28] url: Added bounds checking to parse_login_details()
Added bounds checking when searching for the separator characters within
the login string as this string may not be NULL terminated (For example
it is the login part of a URL). We do this in preference to allocating a
new string to copy the login details into which could then be passed to
parse_login_details() for performance reasons.

In addition to parsing the optional login options from the URL, added
support for parsing them from CURLOPT_USERPWD, to allow the following
supported command line:

Subject: [PATCH 10/28] url: Simplified setstropt_userpwd() following recent
changes
There is no need to perform separate clearing of data if a NULL option
pointer is passed in. Instead this operation can be performed by simply
not calling parse_login_details() and letting the rest of the code do
the work.

Subject: [PATCH 19/28] url: use goto in create_conn() for exception handling
Instead of remembering before each "return" statement which temporary
allocations, if any, need to be freed, take care to set pointers to
NULL when no longer needed and use a goto to a common block to exit
the function and free all temporaries.
No functional change intended. Currently the only temporary buffer in
this function is "proxy" which is already correctly freed when
appropriate, but there will be more soon.

Subject: [PATCH 21/28] netrc: handle longer username and password
libcurl truncates usernames and passwords it reads from .netrc to
LOGINSIZE and PASSWORDSIZE (64) characters without any indication to
the user, to ensure the values returned from Curl_parsenetrc fit in a
caller-provided buffer.
Fix the interface by passing back dynamically allocated buffers
allocated to fit the user's input. The parser still relies on a
256-character buffer to read each line, though.
So now you can include an ~246-character password in your .netrc,
instead of the previous limit of 63 characters.

Subject: [PATCH 22/28] Curl_setopt: handle arbitrary-length username and
password
libcurl truncates usernames, passwords, and options set with
curl_easy_setopt to 255 (= MAX_CURL_PASSWORD_LENGTH - 1) characters.
This doesn't affect the return value from curl_easy_setopt(), so from
the caller's point of view, there is no sign anything strange has
happened, except that authentication fails.
For example:
# Prepare a long (300-char) password.
s=0123456789; s=$s$s$s$s$s$s$s$s$s$s; s=$s$s$s;
# Start a server.
nc -l -p 8888 | tee out & pid=$!
# Tell curl to pass the password to the server.
curl --user me:$s http://localhost:8888 & sleep 1; kill $pid
# Extract the password.
userpass=$(
awk '/Authorization: Basic/ {print $3}' <out |
tr -d '\r' |
base64 -d
)
password=${userpass#me:}
echo ${#password}
Expected result: 300
Actual result: 255
The fix is simple: allocate appropriately sized buffers on the heap
instead of trying to squeeze the provided values into fixed-size
on-stack buffers.

Subject: [PATCH 23/28] url: handle exceptional cases first in
parse_url_login()
Instead of nesting "if(success)" blocks and leaving the reader in
suspense about what happens in the !success case, deal with failure
cases early, usually with a simple goto to clean up and return from
the function.
No functional change intended. The main effect is to decrease the
indentation of this function slightly.

Subject: [PATCH 25/28] url: handle arbitrary-length username and password
before '@'
libcurl quietly truncates usernames, passwords, and options from
before an '@' sign in a URL to 255 (= MAX_CURL_PASSWORD_LENGTH - 1)
characters to fit in fixed-size buffers on the stack. Allocate a
buffer large enough to fit the parsed fields on the fly instead to
support longer passwords.
After this change, there are no more uses of MAX_CURL_OPTIONS_LENGTH
left, so stop defining that constant while at it. The hardcoded max
username and password length constants, on the other hand, are still
used in HTTP proxy credential handling (which this patch doesn't
touch).

Subject: [PATCH 27/28] login options: remove the ;[options] support from
CURLOPT_USERPWD
To avoid the regression when users pass in passwords containing semi-
colons, we now drop the ability to set the login options with the same
options. Support for login options in CURLOPT_USERPWD was added in
7.31.0.
Test case 83 was modified to verify that colons and semi-colons can be
used as part of the password when using -u (CURLOPT_USERPWD).
