* hurd: Fix 64bit fcntl lock implementationSamuel Thibault2018-12-191-3/+3
| | | | | * sysdeps/mach/hurd/fcntl.c (__libc_fcntl): Test against 64bit `cmd' values in the 64bit value cases.
* Do not clobber sp in _hurd_stack_setup.Joseph Myers2018-12-131-1/+1
| | | | | | | | | | | | | GCC mainline now gives errors for an asm that clobbers the stack pointer. According to <https://gcc.gnu.org/ml/gcc-patches/2018-12/msg00932.html> GCC previously ignored such a clobber; thus, this patch removes it from _hurd_stack_setup. Tested with build-many-glibcs.py for i686-gnu. * sysdeps/mach/hurd/i386/init-first.c (_hurd_stack_setup): Do not clobber sp.

* Fix Hurd build with read-only source directory.Joseph Myers2018-11-271-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic for generating sysdeps/mach/hurd/bits/errno.h involves a stamp file and $(move-if-change). The temporary file (generated unconditionally) is generated in the source directory. This means that even if sysdeps/mach/hurd/bits/errno.h is up to date, and has an up to date timestamp, the build will fail if the source directory is read-only. Even with a writable source directory, multiple concurrent builds for i686-gnu with the same source directory could race to access the temporary file (which always has the same name). This patch uses the build directory for the temporary file instead to avoid those problems. (In the case where the file is out of date and the temporary file does need to be moved to the source directory, if there are multiple concurrent builds for i686-gnu with the same source directory, and the source and build directories are on different filesystems, it's possible there might still be races replacing the file in the source directory, depending on exactly how mv handles such cross-filesystem moves. This is certainly no worse than the present situation, where such a case would have races regardless of whether the file is out of date or whether different filesystems are in use.) Tested with a build-many-glibcs.py build for i686-gnu. * sysdeps/mach/hurd/Makefile ($(common-objpfx)stamp-errnos): Use $(hurd-objpfx)bits/errno.h-tmp, not $(hurd)/bits/errno.h-tmp.
* Remove the error handling wrapper from powSzabolcs Nagy2018-11-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce new pow symbol version that doesn't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The wrapper is disabled for sysdeps/ieee754/dbl-64 by using empty w_pow.c and enabled for targets with their own pow implementation or ifunc dispatch on __ieee754_pow by including math/w_pow.c. The compatibility symbol version still uses the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously powl was an alias of pow, now it points to the compatibility symbol with the wrapper, because it still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g. arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The __pow_finite symbol is now an alias of pow. Both __pow_finite and pow set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header.

The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv).

* Fix hurd expected fcntl versionAdhemerval Zanella2018-07-031-1/+0
| | | | | | | | | | | Different than Linux, hurd does not need the OFD locks fix from 06ab719d30b (since OFD locks are current Linux specific). This in turn allows hurd to not provide a fcntl compat symbol. Checked on a i686-gnu with check-abi. * sysdeps/mach/hurd/i386/libc.abilist [GLIBC_2.28] (fcntl): Remove symbol.
* libc: Extend __libc_freeres framework (Bug 23329).Carlos O'Donell2018-06-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The __libc_freeres framework does not extend to non-libc.so objects. This causes problems in general for valgrind and mtrace detecting unfreed objects in both libdl.so and libpthread.so. This change is a pre-requisite to properly moving the malloc hooks out of malloc since such a move now requires precise accounting of all allocated data before destructors are run. This commit adds a proper hook in libc.so.6 for both libdl.so and for libpthread.so, this ensures that shm-directory.c which uses freeit () to free memory is called properly. We also remove the nptl_freeres hook and fall back to using weak-ref-and-check idiom for a loaded libpthread.so, thus making this process similar for all DSOs. Lastly we follow best practice and use explicit free calls for both libdl.so and libpthread.so instead of the generic hook process which has undefined order. Tested on x86_64 with no regressions.

* Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)Adhemerval Zanella2018-06-263-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the OFD ("file private") locks for architectures that support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and F_{SET,GET}L{W}K64 expects a flock64 argument and when using old F_OFD_* flags with a non LFS flock argument the kernel might interpret the underlying data wrongly. Kernel idea originally was to avoid using such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS semantic as default it is possible to provide the functionality and avoid the bogus struct kernel passing by adjusting the struct manually for the required flags. The idea follows other LFS interfaces that provide two symbols: 1. A new LFS fcntl64 is added on default ABI with the usual macros to select it for FILE_OFFSET_BITS=64. 2. The Linux non-LFS fcntl use a stack allocated struct flock64 for F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided struct. 3. Keep a compat symbol with old broken semantic for architectures that do not define __OFF_T_MATCHES_OFF64_T. So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will aliased to fcntl and no adjustment would be required. So to actually use F_OFD_* with LFS support the source must be built with LFS support (_FILE_OFFSET_BITS=64). Also F_OFD_SETLKW command is handled a cancellation point, as for F_SETLKW{64}. Checked on x86_64-linux-gnu and i686-linux-gnu.
