This commit adds two new helper + functions, __ns_rr_cursor_init and __ns_rr_cursor_next, for writing + packet parsers, and struct ns_rr_cursor, struct ns_rr_wire as + supporting types. + + In theory, it is possible to avoid copying the owner name + into the rname field in __ns_rr_cursor_next, but this would need + more functions that work on compressed names. + + Eventually, __res_context_send could be enhanced to preserve the + result of the packet parsing that is necessary for matching the + incoming UDP packets, so that this works does not have to be done + twice. + + Reviewed-by: Siddhesh Poyarekar + (cherry picked from commit 857c890d9b42c50c8a94b76d47d4a61ab6d2f49c) + +diff --git a/include/arpa/nameser.h b/include/arpa/nameser.h +index 6e4808f00d60caf9..c27e7886b7891997 100644 +--- a/include/arpa/nameser.h ++++ b/include/arpa/nameser.h +@@ -103,5 +103,97 @@ libc_hidden_proto (__libc_ns_samename) + must point one past the last byte in the packet. */ + int __ns_name_length_uncompressed (const unsigned char *p, + const unsigned char *eom) attribute_hidden; ++ ++/* Iterator over the resource records in a DNS packet. */ ++struct ns_rr_cursor ++{ ++ /* These members are not changed after initialization. */ ++ const unsigned char *begin; /* First byte of packet. */ ++ const unsigned char *end; /* One past the last byte of the packet. */ ++ const unsigned char *first_rr; /* First resource record (or packet end). */ ++ ++ /* Advanced towards the end while reading the packet. */ ++ const unsigned char *current; ++}; ++ ++/* Returns the RCODE field from the DNS header. */ ++static inline int ++ns_rr_cursor_rcode (const struct ns_rr_cursor *c) ++{ ++ return c->begin[3] & 0x0f; /* Lower 4 bits at offset 3. */ ++} ++ ++/* Returns the length of the answer section according to the DNS header. */ ++static inline int ++ns_rr_cursor_ancount (const struct ns_rr_cursor *c) ++{ ++ return c->begin[6] * 256 + c->begin[7]; /* 16 bits at offset 6. */ ++} ++ ++/* Returns the length of the authority (name server) section according ++ to the DNS header. */ ++static inline int ++ns_rr_cursor_nscount (const struct ns_rr_cursor *c) ++{ ++ return c->begin[8] * 256 + c->begin[9]; /* 16 bits at offset 8. */ ++} ++ ++/* Returns the length of the additional data section according to the ++ DNS header. */ ++static inline int ++ns_rr_cursor_adcount (const struct ns_rr_cursor *c) ++{ ++ return c->begin[10] * 256 + c->begin[11]; /* 16 bits at offset 10. */ ++} ++ ++/* Returns a pointer to the uncompressed question name in wire ++ format. */ ++static inline const unsigned char * ++ns_rr_cursor_qname (const struct ns_rr_cursor *c) ++{ ++ return c->begin + 12; /* QNAME starts right after the header. */ ++} ++ ++/* Returns the question type of the first and only question. */ ++static inline const int ++ns_rr_cursor_qtype (const struct ns_rr_cursor *c) ++{ ++ /* 16 bits 4 bytes back from the first RR header start. */ ++ return c->first_rr[-4] * 256 + c->first_rr[-3]; ++} ++ ++/* Returns the clss of the first and only question (usally C_IN). */ ++static inline const int ++ns_rr_cursor_qclass (const struct ns_rr_cursor *c) ++{ ++ /* 16 bits 2 bytes back from the first RR header start. */ ++ return c->first_rr[-2] * 256 + c->first_rr[-1]; ++} ++ ++/* Initializes *C to cover the packet [BUF, BUF+LEN).

The other arguments to the + memmove call here also appear to be wrong; w and s point just *after* + the destination and source for copying the rest of the number, so the + size needs to be subtracted to get appropriate pointers for the + copying. Adjust the memmove call to conform to the apparent intent of + the code, so fixing the -Wstringop-overflow error. + + Now, if the original code were ever executed, a buffer overrun would + result. However, I believe this code (introduced in commit + edc1686af0c0fc2eb535f1d38cdf63c1a5a03675, "vfprintf: Reuse work_buffer + in group_number", so in glibc 2.26) is unreachable in prior glibc + releases (so there is no need for a bug in Bugzilla, no need to + consider any backports unless someone wants to build older glibc + releases with GCC 12 and no possibility of this buffer overrun + resulting in a security issue). + + work_buffer is 1000 bytes / 250 wide characters. This case is only + reachable if an initial part of the number, plus a grouped copy of the + rest of the number, fail to fit in that space; that is, if the grouped + number fails to fit in the space. In the wide character case, + grouping is always one wide character, so even with a locale (of which + there aren't any in glibc) grouping every digit, a number would need + to occupy at least 125 wide characters to overflow, and a 64-bit + integer occupies at most 23 characters in octal including a leading 0. + In the narrow character case, the multibyte encoding of the grouping + separator would need to be at least 42 bytes to overflow, again + supposing grouping every digit, but MB_LEN_MAX is 16. So even if we + admit the case of artificially constructed locales not shipped with + glibc, given that such a locale would need to use one of the character + sets supported by glibc, this code cannot be reached at present. (And + POSIX only actually specifies the ' flag for grouping for decimal + output, though glibc acts on it for other bases as well.) + + With binary output (if you consider use of grouping there to be + valid), you'd need a 15-byte multibyte character for overflow; I don't + know if any supported character set has such a character (if, again, + we admit constructed locales using grouping every digit and a grouping + separator chosen to have a multibyte encoding as long as possible, as + well as accepting use of grouping with binary), but given that we have + this code at all (clearly it's not *correct*, or in accordance with + the principle of avoiding arbitrary limits, to skip grouping on + running out of internal space like that), I don't think it should need + any further changes for binary printf support to go in. + + On the other hand, support for large sizes of _BitInt in printf (see + the N2858 proposal) *would* require something to be done about such + arbitrary limits (presumably using dynamic allocation in printf again, + for sufficiently large _BitInt arguments only - currently only + floating-point uses dynamic allocation, and, as previously discussed, + that could actually be replaced by bounded allocation given smarter + code). + + Tested with build-many-glibcs.py for aarch64-linux-gnu (GCC mainline). + Also tested natively for x86_64. + + (cherry picked from commit db6c4935fae6005d46af413b32aa92f4f6059dce) + +diff --git a/stdio-common/vfprintf-internal.c b/stdio-common/vfprintf-internal.c +index 3f3d1e148a8e7fda..53d93b2f07ecb261 100644 +--- a/stdio-common/vfprintf-internal.c ++++ b/stdio-common/vfprintf-internal.c +@@ -2154,7 +2154,8 @@ group_number (CHAR_T *front_ptr, CHAR_T *w, CHAR_T *rear_ptr, + copy_rest: + /* No further grouping to be done.
