* powerpc: Fix tabort usage in syscallsPaul E. Murphy2015-08-251-0/+1
| | | | | | | | | | | | | | | | | | | Fix usage of tabort in generated syscalls. r0 has special meaning when used with this instruction, thus it will not generate persistent errors, nor return an error code. This mitigates poor CPU usage when performing elided critical sections. Additionally, transactions should be aborted when entering a user invoked syscall. Otherwise the results of the transaction may be undefined. 2015-08-25 Paul E. Murphy <murphyp@linux.vnet.ibm.com> * sysdeps/powerpc/powerpc32/sysdep.h (ABORT_TRANSACTION): Use register other than r0 for tabort, it has special meaning. * sysdeps/powerpc/powerpc64/sysdep.h (ABORT_TRANSACTION): Likewise * sysdeps/unix.sysv/linux/powerpc/syscall.S (syscall): Abort transaction before starting syscall.
* Remove __ASSUME_IPC64Andreas Schwab2015-08-2423-706/+1
| | | | | | | PowerPC has always used __IPC_64 like most other architectures, which means that __ASSUME_IPC64 can be always true. Also, all other architecture implementations that use the ipc syscall are effectively identical to the generic version and can be removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For ia32 PIC, the first thing of many syscalls does is to call __x86.get_pc_thunk.reg to load PC into reg in case there is an error, which is required for setting errno. In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_RETURN and INLINE_SYSCALL_ERROR_RETURN so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT. INLINE_SYSCALL_ERROR_RETURN is designed to take the negative error number returned from the majority of Linux kernels for which negating is a no-op with INTERNAL_SYSCALL_ERRNO.

| | | | | | | | | | | | | | | | The semi-recent SYSCALL_CANCEL inclusion broke hppa due to the sysdep.h headers not including the unix/sysdep.h headers. Rework the includes so we match the other ports: * hppa/sysdep.h: - Do not include sys/syscall.h as the unix sysdep.h headers do it. - Do not include config.h as libc-symbols.h does it, and it has no #ifdef multiple-include protection, and it breaks when some files do things like #undef __OPTIMIZE__. * sysdeps/unix/sysv/linux/hppa/sysdep-cancel.h: - Drop the generic/sysdep.h as the unix sysdep.h headers include it. * sysdeps/unix/sysv/linux/hppa/sysdep.h: - Change to the unix & core hppa sysdep header stacks. - Undef a few defines that the core headers already set up for us.
* hppa: rewrite INLINE_SYSCALLMike Frysinger2015-07-291-22/+7
| | | | | | | | | | | | | | | | | | | The semi-recent SYSCALL_CANCEL macro imposes a slight nuance on the implementation of INLINE_SYSCALL: the nr argument cannot be expanded directly but must be passed on to another macro which may expand it. Most arches don't notice because INLINE_SYSCALL is defined in terms of INTERNAL_SYSCALL which has the additional layer of expansion, but on hppa, it was attempting to expand it directly. That causes build errors like so: ../sysdeps/unix/sysv/linux/sigsuspend.c: In function '__sigsuspend': ../sysdeps/unix/sysv/linux/sigsuspend.c:31:62: error: implicit declaration of function 'LOAD_ARGS___SYSCALL_NARGS' ../sysdeps/unix/sysv/linux/sigsuspend.c:31:304: error: called object 'LOAD_ARGS___SYSCALL_NARGS(set, 8)' is not a function So rewrite hppa's INLINE_SYSCALL to use INTERNAL_SYSCALL like other arches do. This is also a nice clean up as the two macros had quite a bit of duplicated logic.
* Extend local PLT reference checkH.J. Lu2015-07-291-3/+5
| | | | | | | | | | | | | | On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with R_*_GLOB_DAT relocation against the same symbol. This patch extends local PLT reference check to support alternate relocations. [BZ #18078] * scripts/check-localplt.awk: Support alternate relocations. * scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL sections. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and malloc entries with + REL R_386_GLOB_DAT. * sysdeps/x86_64/localplt.data: New file.
* ia64: drop __tls_get_addr from expected ld.so plt usageMike Frysinger2015-07-281-4/+3
| | | | | | This file was updated with an educated guess as to the symbols needed, but on ia64, we don't have __tls_get_addr calls, so drop it from the list.
* ia64: clean up old kernel headers cruftMike Frysinger2015-07-281-4/+0
| | | | | | This define made more sense in the pre-sanitized kernel headers days, but since we require kernel versions that are sanitized, we don't need this hack anymore.
* Fix order of arguments to rt_sigprocmask syscall when setting the signal maskChung-Lin Tang2015-07-242-6/+6

* ia64: sigaction.h: fix sa_flags orderingMike Frysinger2015-07-231-1/+1
| | | | | | | Since ia64 is little endian, sa_flags has to come before the padding when splitting it from 64bits to 32bits. Reported-by: Joseph Myers <joseph@codesourcery.com>
* ia64: msg.h: fix msg_qnum/msg_qbytes typesMike Frysinger2015-07-211-4/+9
| | | | | These two fields have dedicated types, so change the ia64 header to match all the other arches. This fixes the conform test for msg.h.
* ia64: stat.h: rename pad0 to __glibc_reserved0Mike Frysinger2015-07-211-2/+2
| | | | | This fixes the conform test for the stat.h header and makes it match all the other arches.
* ia64: sifaction.h: change sa_flags to an intMike Frysinger2015-07-211-1/+2
| | | | | This fixes the conform test for the sigaction.h header and makes it match all the other arches.
* ia64: siginfo.h: delete siginfo nameMike Frysinger2015-07-211-1/+1
| | | | | This fixes the conform test for the siginfo.h header and makes it match all the other arches.
* tile: Fix BZ #18508 (makecontext yield infinite backtrace)Chris Metcalf2015-07-212-4/+6
| | | | | | | | | | | | | | | It turns out tile suffered from the same problem as S390. However, disabling CFI information for the __startcontext on tile was not sufficient to fix the problem; I think the backtracer will just blindly try to follow the link register (lr) in that case. Instead, the change adds a cfi_undefined directive for "lr" and then arranges to call __startcontext directly when the new context starts, rather than just synthesizing a return to it. In addition to being a bit easier now to understand the control flow, this also allows the cfi_undefined directive to be placed in a way that causes it to be in force at the address that the "lr" from the called function points to.
* sparc: fix sigaction for 32bit builds [BZ #18694]Mike Frysinger2015-07-201-0/+4
| | | | | | | | | | | Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction struct to pass conform tests, but it ended up also changing the ABI for 32 bit builds. For 64 bit builds, changing the long to two ints works, but for 32 bit builds, it inserts 4 extra bytes. This leads to many packages randomly failing like bash that spews things like: configure: line 471: wait_for: No record of process 0 Bracket the new member by a wordsize check to fix the ABI for 32bit.
