* alpha: Fix tls-macros.h gentoo/2.18Richard Henderson2014-01-251-11/+11
| | | | | | | | Reported to the gcc bugzilla, there was a missing dependency on $gp that let the compiler generated $gp reload be scheduled across the macros here. (cherry picked from commit 4ab6acaebd0047dc37c6493946484be9f1b4920b)
* ARM: Fix clone build for ARMv4Will Newton2014-01-251-7/+1
| | | | | | | | | | | | | | | | | ARMv4 does not have the blx instruction, so use the BLX macro which handles abstracting this for us. Build tested for armv7, armv4t and armv4. ports/ChangeLog.arm: 2014-01-24 Will Newton <will.newton@linaro.org> [BZ #16499] * sysdeps/unix/sysv/linux/arm/clone.S: Use BLX macro instead of blx instruction directly.

* Fix build on pre-v9 32-bit Sparc.David S. Miller2014-01-061-1/+2
| | | | | | | | | | | We cannot use fnegd in this code, as fnegd was added in v9. Only fnegs exists in v8 and earlier. [BZ #15985] * sysdeps/sparc/sparc32/fpu/s_fdim.S (__fdim): Do not use fnegd on pre-v9 cpus, use a fnegs+fmovs sequence instead. (cherry picked from commit 2216e48645dbd297cdc0f4050fdfc0b52e2a4ab8)

* BZ #15754: CVE-2013-4788Carlos O'Donell2014-01-0615-2/+302
| | | | | | | | | | | | | | The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value. (cherry picked from commit c779e9df75256f19c7be8d12b2d163e2016a63f4)
* Fix stack overflow due to large AF_INET6 requestsSiddhesh Poyarekar2014-01-061-2/+18
| | | | | | | | | | Resolves #16072 (CVE-2013-4458). This patch fixes another stack overflow in getaddrinfo when it is called with AF_INET6. The AF_UNSPEC case was fixed as CVE-2013-1914, but the AF_INET6 case went undetected back then. (cherry picked from commit 6f95434fd488e9b72117f9b93ec2e2dbf397a4d3)

* Fix PI mutex check in pthread_cond_broadcast and pthread_cond_signalSiddhesh Poyarekar2014-01-064-11/+12
| | | | | | | | | | Fixes BZ #15996. The check had a typo - it checked for PTHREAD_MUTEX_ROBUST_NP instead of PTHREAD_MUTEX_ROBUST_NORMAL_NP. It has now been replaced by the already existing convenience macro USE_REQUEUE_PI. (cherry picked from commit 2770d15e7e880821fc586619c59eb45180628e16)
* ARM: Fix clone code when built for Thumb.Will Newton2014-01-063-2/+14
| | | | | | | | | | | | | | | | The mov lr, pc instruction will lose the Thumb bit from the return address so use blx lr instead. ports/ChangeLog.arm: 2013-08-30 Will Newton <will.newton@linaro.org> [BZ #15909] * sysdeps/unix/sysv/linux/arm/clone.S (__clone): Use blx instead of mov lr, pc.

* ia64: add __ prefix to pt_all_user_regs/ia64_fpreg [BZ #762]Mike Frysinger2014-01-063-5/+5
| | | | | | | | | | | | This addresses a long standing collision between userspace headers and kernel headers only on ia64 systems. All other types have a __ prefix in the ptrace headers except these two. Let's finally namespace these. Verified that at least strace still builds after this change, as well as after deleting all the struct hacks it has specifically for ia64.

* ptrace.h: add __ prefix to ptrace_peeksiginfo_argsMike Frysinger2014-01-067-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | All the other ptrace structures in this file have a __ prefix except this new one. This in turn causes build problems for most packages that try to use ptrace such as strace: gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \ -I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \ -MF .deps/process.Tpo -c -o process.o ../../process.c In file included from ../../process.c:63:0: /usr/include/linux/ptrace.h:58:8: error: redefinition of 'struct ptrace_peeksiginfo_args' struct ptrace_peeksiginfo_args { ^ In file included from ../../defs.h:159:0, from ../../process.c:37: /usr/include/sys/ptrace.h:191:8: note: originally defined here struct ptrace_peeksiginfo_args ^ Since this struct was introduced in glibc-2.18, there shouldn't be any real regressions with adding the __ prefix.

* Don't use broken DL_AUTO_FUNCTION_ADDRESS()Guy Martin2013-11-248-61/+71
| | | | | | | | | | | | | | | | | On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the variable fptr[2] in it's own scope. The content of fptr[] is thus undefined right after the macro exits. Newer gcc's (>= 4.7) reuse the stack space of this variable triggering a segmentation fault in dl-init.c:69. To fix this we rewrite the macros to make the call directly to init and fini without needing to pass back a constructed function pointer.

* hppa: add fanotify_markMike Frysinger2013-11-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | Another example of all the 64bit arches getting the definition via a common file, but the 32bit ones all adding it by themselves and hppa was missed. I'm not entirely sure about the usage of GLIBC_2.19 symbols here. We'd like to backport this so people can use it, but it means we'd be releasing a glibc-2.17/glibc-2.18 with a GLIBC_2.19 symbol in it. But maybe it won't be a big deal since you'd only get that 2.19 ref if you actually used the symbol ? There hasn't been a glibc release where hppa worked w/out a bunch of patches, so in reality there's only two distros that matter -- Gentoo and Debian.

* mips: add clock_{g,s}ettime symbol compat hacksMike Frysinger2013-08-164-0/+28
| | | | | | | we kind of screwed ourselves into a corner by having the clock symbols exported only with the glibc-2.0 version ... this patch fixes the export so all new binaries built against librt will use the correct glibc-2.2 symbol version
* arm: fix PIC vs SHARED typosDavid Lamparter2013-08-162-4/+4
| | | | | | | | | | | | | | the logic in setjmp/__longjmp incorrectly tie to "PIC" to figure out whether the code is going into a shared library when it should be using "SHARED". otherwise, building static PIC code goes wrong. https://bugs.gentoo.org/336914 http://sourceware.org/ml/libc-ports/2011-09/msg00018.html 2011-09-19 David Lamparter <equinox-gentoo@diac24.net> * sysdeps/arm/eabi/setjmp.S: Change PIC to SHARED. * sysdeps/arm/eabi/__longjmp.S: Likewise

* gentoo: support running tests under sandboxStephanie J. Lockwood-Childs2013-08-163-3/+3
| | | | | | | | | | | | | | | | | when glibc runs its tests, it does so by invoking the local library loader. in Gentoo, we build/run inside of our "sandbox" which itself is linked against libdl (so that it can load libraries and pull out symbols). the trouble is that when you upgrade from an older glibc to the new one, often times internal symbols change name or abi. this is normally OK as you cannot use libc.so from say version 2.3.6 but libpthread.so from say version 2.5, so we always say "keep all of the glibc libraries from the same build". but when glibc runs its tests, it uses dynamic paths to point to its new local copies of libraries. if the test doesnt use libdl, then glibc doesnt add its path, and when sandbox triggers the loading of libdl, glibc does so from the host system system. this gets us into the case of all libraries are from the locally compiled version of glibc except for libdl.so. http://bugs.gentoo.org/56898
