* Compatible stack protector for non Thread Local storageNatanael Copa2011-12-231-7/+1
| | | | | | | Before we had thread local storage the __stack_chk_guard was a global variable that was referenced to by the older binaries. We since then have changed ABI so this patch can probably go away.
* Correct ssp codePeter S. Mazinger2011-03-031-18/+7
| | | | | | | | Avoid using strong_alias in ssp, some archs dislike it. Make stack_chk_guard static. Export __stack_smash_handler only if compatibility option is enabled. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>

* tempname: fix int precision warningsMike Frysinger2011-02-221-1/+4
| | | | | | | | | | | The printf precision takes an integer, not a size_t. Otherwise we get: libc/misc/internals/tempname.c: In function '___path_search': libc/misc/internals/tempname.c:116: warning: field precision should have type 'int', but argument 3 has type 'size_t' field precision should have type 'int', but argument 5 has type 'size_t' Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* parse_config: discard rest of incomplete lineNatanael Copa2010-10-141-0/+7
| | | | | | | | If line is longer then size of given buffer and buffer is not allocated by the config parser itself, then discard rest of line. Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* config parser: always initialize line pointerNatanael Copa2010-10-141-2/+1
| | | | | | | | We must always initialize line pointer since data pointer might have changed due to a realloc (in getserv.c for example). Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* config parser: do not assume that realloc return same pointerNatanael Copa2010-10-141-5/+4
| | | | | | | | | | | | We need to update the parser->line pointer on realloc and do not initialize the token array til after the potensial realloc in bb_get_chunk_with_continuation(). While here, also replace a realloc() with malloc() where pointer always is NULL. Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* config parser: fix memory corruptionTimo Teräs2010-08-061-2/+2
| | | | | | | | | | | | fgets will happily write over allocated area limits. Adjusted the buffer size according to how much is already read. Also increase the maximum default line length, as 80 is slightly small. It might be better if bb_get_chunk_with_continuation would reallocate the line buffer if it was not user given.

* Revert "don't make __errno_location / __h_errno_location hidden"Austin Foxley2010-07-062-0/+4
| | | | | | | | This reverts commit 0d6ee549bc86fd330672a79d9a87d2c3825eea67. We need to find a solution that will work in shared and static libraries Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* don't make __errno_location / __h_errno_location hiddenPeter Korsgaard2010-07-052-4/+0
| | | | | | | | | | | | | Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089) __errno_location / __h_errno_location access has to go through the PLT like malloc/free, so the linuxthread variants gets used instead when compiling with -pthread.

| | | | | | | | | | Commit 2e53dd645d5348f207cec7f8595969dc566c5a55 workarounds GCC bug when accessing _locale_init and _stdio_init.

* static build: fix internal locking weaks to get pulled in alwaysTimo Teras2010-05-071-0/+35
| | | | | | | | | | | Linker is smart and does not pull in weaks.os, ever. This happens because that compilation unit does not get strong references and ld eliminates dead code. We really need the weaks for static build in a compilation unit that is always there, otherwise it won't work.
