2011-10-01tests: add fallback for mktemp()Mike Frysinger
If SuSv3 legacy support is disabled, then mktemp() isn't available, and we end up getting a lot of build errors. So add a fallback built on top of tempnam() since that currently cannot be disabled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-09-15Defeat compiler optimization which assumes function addresses are never NULLDenys Vlasenko
From email: A warning for people who can be hit by the same or similar issue: gcc 4.1.2 with -march=i486 here with -Os and even with -O2 or -O is "optimizing away" the check if (_stdio_term) in libc/stdlib/_atexit.c which results in a "call 0" and a segfault at exit if you do not happen to link in stdio.

2011-08-26inet: build all res_* and ns_* functions conditionallyDaniel Mack
This patch changes the build system so that all DNS resolver related functions (ie, those starting with dn_, ns_ and res_) are only built if UCLIBC_HAS_RESOLVER_SUPPORT is set. This means that the libc will lack support for things that existed in the library before unless this new config option is set. On the other hand, if users really need support for resolver functions, they now get a more complete set, and the library is smaller than before it is deselected.

2011-07-27ldso/mips: dlsym() incorrectly matches undefined symbolsKevin Cernekee
check_match() relies on checking for (sym->st_value == 0) to see if the symbol is undefined. This works reasonably well on most architectures, such as ARM or i386: $ readelf -s /lib32/libcap.so.2 | grep -E "\<malloc\>" 17: 00000000 0 FUNC GLOBAL DEFAULT UND malloc@GLIBC_2.0 (2) However, on MIPS, libbfd puts nonzero data in the st_value field to facilitate resetting the symbol's GOT entry if the library that defines the symbol gets unloaded: $ mipsel-linux-readelf -s libfoo.so | grep -E "\<malloc\>" 74: 00003140 0 FUNC GLOBAL DEFAULT UND malloc This can cause check_match to report a false positive when examining the external symbol reference. Consequently dlsym() will return a bad pointer to the caller. Use the special MIPS logic from glibc-ports-2.13 to avoid this situation.

2011-07-27ldso/mips: Enable bootstrap relocationsKevin Cernekee
_dl_reltypes_tab[] is an array of pointers to constant strings: Contents of section .data: 20000 01000000 02000000 00000000 00000000 ................ 20010 70e50000 7ce50000 88e50000 94e50000 p...|........... ^^^^^^^^ ^^^^^^^^ ^^^^^^^^ ^^^^^^^^ (pointers are LE) Contents of section .rodata: e570 525f4d49 50535f4e 4f4e4500 525f4d49 R_MIPS_NONE.R_MI e580 50535f31 36000000 525f4d49 50535f33 PS_16...R_MIPS_3 e590 32000000 525f4d49 50535f52 454c3332 2...R_MIPS_REL32 These pointers require relocation: DYNAMIC RELOCATION RECORDS OFFSET TYPE VALUE 00000000 R_MIPS_NONE *ABS* 0001fffc R_MIPS_REL32 *ABS* 00020010 R_MIPS_REL32 *ABS* 00020014 R_MIPS_REL32 *ABS* 00020018 R_MIPS_REL32 *ABS* On MIPS, only GOT relocations are currently handled by ldso during startup. The net effect is that when running with "LD_DEBUG=reloc", ldso itself crashes before the program even starts. This is caused by _dl_dprintf() dereferencing an unadjusted string pointer such as 0xe570. This patch enables the missing relocations and allows LD_DEBUG to work as designed.

2011-06-29libc: add missing lock initialization in vswprintfMaksim Rayskiy
Unlike vsnprintf, vswprintf does not properly initialize locking elements of FILE structure, which in some unfortunate cases can result in lockups in _vfwprintf_internal. Interesting, the initialization code was removed in 2a915734a32c5aec9a6a76c13bcb074d30e64171 at the same time as it was added to vsnprintf.

On FDPIC platforms, functions are passed by function descriptor, not by pointers. If you don't specify ELF_RTYPE_CLASS_DLSYM when calling _dl_find_hash() the return value from dlsym() will be a pointer not a function descriptor, crashing the program.
