* htl: Avoid exposing unixoid functionsSamuel Thibault2020-01-131-0/+3
| | | | C11 threads should not expose them.
* hurd: Do not make sigprocmask available in ld.soFlorian Weimer2019-12-181-2/+2
| | | | | | | | | | | After commit f7649d5780aa4682393b9daedd653e4d9c12784c ("dlopen: Do not block signals"), the dynamic linker no longer uses sigprocmask, which means that it does not have to be made available explicitly on hurd. This reverts commit 892badc9bbcd4a6f8c2eb6c8a99be3aa22517532 ("hurd: Make __sigprocmask GLIBC_PRIVATE") and commit d5ed9ba29a3c818b3433a1784862494968abda45 ("hurd: Fix ld.so link"), but keeps the comment changes from the second commit.
* hurd: Fix __close_nocancel_nostatus availabilitySamuel Thibault2019-12-131-0/+1
| | | | | | | | | | | | | | Not only libc/rtld use __close_nocancel_nostatus. * sysdeps/mach/hurd/Makefile [$(subdir) == io] (sysdep_routines): Add close_nocancel_nostatus. * sysdeps/mach/hurd/Versions (libc): Add __close_nocancel_nostatus to GLIBC_PRIVATE. * sysdeps/mach/hurd/not-cancel.h (__close_nocancel_nostatus): Declare function instead of defining inline. [IS_IN (libc) || IS_IN (rtld)] (__close_nocancel_nostatus): Make function hidden. * sysdeps/mach/hurd/close_nocancel_nostatus.c: New file.
* hurd: Fix ld.so __access override from libcSamuel Thibault2019-12-011-4/+4
| | | | | | ld.so symbols to be overriden by libc need to be extern to really get overriden. __access happens to have never been exposed, putting it to GLIBC_PRIVATE.
* hurd: Fix ld.so __getcwd override from libcSamuel Thibault2019-12-011-4/+4
| | | | | | ld.so symbols to be overriden by libc need to be extern to really get overriden. __getcwd happens to have never been exposed, putting it to GLIBC_PRIVATE.
* hurd: Make __sigprocmask GLIBC_PRIVATESamuel Thibault2019-12-011-4/+4
| | | | We do not need to expose it.
* hurd: Fix ld.so linkSamuel Thibault2019-12-011-2/+2
| | | | | Since a2e8aa0d9ea6 ("Block signals during the initial part of dlopen") dl_open uses sigprocmask, so we need a stub implementation.
* hurd: Fix some ld.so symbol override from libcSamuel Thibault2018-07-271-5/+14
| | | | | | | | | | | | | | 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.
