* hppa: Update lowlevellock.h.Carlos O'Donell2014-04-291-22/+30
| | | | | Cleanup and remove old lll_private_futex_wake macro and add generic support for PI-aware futexes.
* Fixed and unified pthread_once.Torvald Riegel2014-04-111-93/+0
| | | | | | | [BZ #15215] This unifies various pthread_once architecture-specific implementations which were using the same algorithm with slightly different implementations. It also adds missing memory barriers that are required for correctness.
* Move __PTHREAD_SPINS definition to architecture specific headerAdhemerval Zanella2014-04-091-0/+3
| | | | | | | This patch moves the __PTHREAD_SPINS definition to arch specific header since pthread_mutex_t layout is also arch specific. This leads to no need to defining __PTHREAD_MUTEX_HAVE_ELISION and thus removing of the undefined compiler warning.
* Fix __ASSUME_SENDMMSG issues (bug 16611).Joseph Myers2014-02-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the issues for accept4 and recvmmsg, __ASSUME_SENDMMSG is also confused about whether it relates to function availability or socketcall operation availability, and the conditions for the definition are always wrong (sendmmsg appeared in Linux kernel 3.0, not 2.6.39); this is now bug 16611. This patch splits the macro into separate macros like those for accept4 and recvmmsg, defining them for appropriate kernel versions.

* Fix __ASSUME_RECVMMSG issues (bug 16610).Joseph Myers2014-02-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the issues for accept4, __ASSUME_RECVMMSG is also confused about whether it relates to function availability or socketcall operation availability; this is now bug 16610. Nothing actually tests __ASSUME_RECVMMSG for function availability, but implicit in the definition in kernel-features.h is the idea that it makes sense when the syscall is available and socketcall is not being used. As with accept4, there are architectures where the syscall was added later than the socketcall operation, meaning that assuming glibc is built with recent enough kernel headers, it does not attempt to use socketcall for these operations and __ASSUME_RECVMMSG gets defined for kernels >= 2.6.33 even when the syscall was only added later. This patch splits the macro into separate macros like those used for accept4; having similar macro structure in both cases (and for sendmmsg once I've dealt with that) seems likely to be less confusing than having a different structure on the basis of nothing actually needing to assume the recvmmsg function works. Appropriate definitions are added for all architectures. Architecture-specific note: Tile's kernel-features.h says "TILE glibc support starts with 2.6.36", which is accurate in that 2.6.36 was the first kernel version with Tile support, and on that basis I've made that header define __ASSUME_RECVMMSG_SYSCALL unconditionally. However, Tile's configure.ac has arch_minimum_kernel=2.6.32. Since arch_minimum_kernel is meant to reflect only kernel.org kernel versions, I think that should change to 2.6.36. (If using glibc with kernel versions from before a port went in kernel.org, it's your responsibility to change arch_minimum_kernel in a local patch, and at the same time to adjust any __ASSUME_* definitions that may not be correct for your older kernel; for developing the official glibc it should only ever be necessary to consider what official kernel.org releases support.) Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch.

* Fix __ASSUME_ACCEPT4 issues (bug 16609).Joseph Myers2014-02-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In <https://sourceware.org/ml/libc-alpha/2013-12/msg00008.html>, Aurelien noted issues with the definition of __ASSUME_ACCEPT4, which I discussed in more detail in <https://sourceware.org/ml/libc-alpha/2013-12/msg00014.html>; these are now bug 16609. As previously noted, __ASSUME_ACCEPT4 is used in two ways: * In OS-independent code, to mean "accept4 can be assumed to work rather than fail with ENOSYS". It doesn't matter whether it's implemented with socketcall or a separate syscall. * In Linux-specific code, to mean "the socketcall multiplex syscall can be assumed to handle the accept4 operation. When used in Linux-specific code, it *never* refers to anything relating to the accept4 syscall, only to the socketcall multiplexer. This patch splits the macro into separate __ASSUME_ACCEPT4_SOCKETCALL, __ASSUME_ACCEPT4_SYSCALL and __ASSUME_ACCEPT4 to clarify the different cases involved. A macro __ASSUME_SOCKETCALL is added for convenience in writing logic relating to all socketcall architectures. In addition, to address the issue of architectures where socketcall support for accept4 was added before a separate syscall was added (and so the separate syscall should not be used unless known to be present or fallback to socketcall is available), a fourth macro __ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL is added to indicate that the syscall became available at the same time as socketcall support. This is then used in the relevant places in a conditional determining whether to undefine __NR_accept4 (the simple approach to avoiding the syscall's presence causing problems; I didn't try to implement runtime fallback from the syscall to socketcall). Architecture-specific note: alpha defined __ASSUME_ACCEPT4 for 2.6.33 and later, but actually the syscall was added for alpha in 3.2, so this patch uses the correct condition for __ASSUME_ACCEPT4_SYSCALL there. Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch.

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-121-1/+1

The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch prepares for moving arm from ports to libc (see overall plan at <https://sourceware.org/ml/libc-alpha/2014-01/msg00373.html> and discussion of ordering starting at <https://sourceware.org/ml/libc-ports/2014-01/msg00071.html>) by reversing the #include order between arm and alpha, so that arm can move early as a test for the general pattern of moving architectures. MicroBlaze files (that used the same alpha files) were made to include the files directly from their new locations rather than indirecting.

* ARM: Don't apply pointer encryption to the frame pointerWill Newton2014-01-141-2/+6
| | | | | | | | | | | | | | | | | | | | | The frame pointer register is rarely used for that purpose on ARM and applications that look at the contents of the jmp_buf may be relying on reading an unencrypted value. For example, Ruby uses the contents of jmp_buf to find the root set for garbage collection so relies on this pointer value being unencrypted. Without this patch the Ruby testsuite fails with a segmentation fault. ports/ChangeLog.arm: 2013-01-14 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S: Don't apply pointer encryption to fp register. * sysdeps/arm/setjmp.S: Likewise. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Add fp to register list, remove a4. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE_LOAD): New macro.
* Use separate libc.abilist for MIPS o32 soft float.Joseph Myers2014-01-072-0/+2259
| | | | | | | | | | | | | | | | | | | | Examining MIPS test results showed an ABI test failure that I must have missed in 2.18 testing: hard-float and soft-float o32 no longer have the same set of symbols (because of the __mips_fpu_getcw and __mips_fpu_setcw functions, present for hard-float only, used by fpu_control.h for hard-float MIPS16) and so need separate ABI test baselines (they always were ABI-incompatible - the function-calling interface is different - but previously had the same set of symbols and versions so didn't need separate baselines). Tested for hard-float and soft-float o32. * sysdeps/unix/sysv/linux/mips/mips32/nptl/libc.abilist: Move to .... * sysdeps/unix/sysv/linux/mips/mips32/fpu/nptl/libc.abilist: ... here. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/nptl/libc.abilist: New file.

* MIPS: Fix RLIM64_INFINITY constant for O32 and N32 ABIsAurelien Jarno2013-11-277-30/+60
| | | | | | | Fix the RLIM64_INFINITY constant for O32 and N32 ABIs to match the kernel one. Change the getrlimit64/setrlimit64 into old compat symbols, and provide the Linux generic getrlimit64/setrlimit64 functions as GLIBC_2_19 version.
* MIPS: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constantAurelien Jarno2013-11-272-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RLIM64_INFINITY was supposed to be a glibc convention rather than anything seen by the kernel, but it ended being passed to the kernel through the prlimit64 syscall. On O32 and N32 ABIs, we therefore end-up with different values on the userland and kernel side: * On the kernel side, the value is defined for all architectures as include/uapi/linux/resource.h: #define RLIM64_INFINITY (~0ULL) * On the GNU libc side, the value is defined in ports/sysdeps/unix/sysv/linux/mips/bits/resource.h: For the O32 and N32 ABI: # define RLIM64_INFINITY 0x7fffffffffffffffULL and for the N64 ABI: # define RLIM64_INFINITY 0xffffffffffffffffUL This was not a problem until the prlimit64 syscall was wired in the 2.6.36 kernel. Given the GLIBC uses the prlimit64 syscall to implement getrlimit64 and setrlimit64, pam_limits.so is setting the limits to a very big value instead of infinity. As a normal user process can later only decrease the value and not increase it, it will later get and EPERM error when trying to set the value to infinity with setrlimit. The GLIBC has this constant for more than 7 years, and as it is defined in a header file, it means a lot of binaries are in the wild. This patch fixes that by adding a wrapper to fix the value passed to or received from the kernel, before or after calling the prlimit64 syscall.
