2018-08-01hurd: Fix exec usage of mach_setup_threadSamuel Thibault
Exec needs that mach_setup_thread does *not* set up TLS since it works on another task, so we have to split this into mach_setup_tls. * mach/mach.h (__mach_setup_tls, mach_setup_tls): Add prototypes. * mach/setup-thread.c (__mach_setup_thread): Move TLS setup to... (__mach_setup_tls): ... new function. (mach_setup_tls): New alias. * hurd/hurdsig.c (_hurdsig_init): Call __mach_setup_tls after __mach_setup_thread. * sysdeps/mach/hurd/profil.c (update_waiter): Likewise. * sysdeps/mach/hurd/setitimer.c (setitimer_locked): Likewise. * mach/Versions [libc] (mach_setup_tls): Add symbol. * sysdeps/mach/hurd/i386/libc.abilist (mach_setup_tls): Likewise.

2018-07-27hurd: Fix some ld.so symbol override from libcSamuel Thibault
ld.so symbols to be overriden by libc need to be extern to really get overriden. More fixes are needed to avoid the hidden attribute. * sysdeps/mach/hurd/Versions (libc): Make __access and __access_noerrno external so they can override the ld symbols. (ld): Make __access, __read, __sbrk, __strtoul_internal, __write, __writev, __open64, __access_noerrno extern so they can be overrided. * sysdeps/mach/hurd/i386/libc.abilist: Update accordingly. * sysdeps/mach/hurd/i386/ld.abilist: Update accordingly.

2018-07-05Add renameat2 function [BZ #17662]Florian Weimer
The implementation falls back to renameat if renameat2 is not available in the kernel (or in the kernel headers) and the flags argument is zero. Without kernel support, a non-zero argument returns EINVAL, not ENOSYS. This mirrors what the kernel does for invalid renameat2 flags.
2018-07-03Fix hurd expected fcntl versionAdhemerval Zanella
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.
2018-06-26Revert hurd errno.h changesAdhemerval Zanella
Patch 06ab719d30b01 wrongly added mach errno.h changes.
2018-06-26Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)Adhemerval Zanella
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.
