2021-12-28hurd: Fix static-PIE startupSamuel Thibault1-7/+3
hurd initialization stages use RUN_HOOK to run various initialization functions. That is however using absolute addresses which need to be relocated, which is done later by csu. We can however easily make the linker compute relative addresses which thus don't need a relocation. The new SET_RELHOOK and RUN_RELHOOK macros implement this.
2020-11-15hurd: Remove some remnants of cthreadsSamuel Thibault1-7/+6
Libc has actually been using mach's lock-internal.h mutex for a long time already.
2016-09-22hurdmalloc: Run fork handler as late as possible [BZ #19431]Samuel Thibault1-9/+6
This is the hurd-specific follow-up for 29d794863cd6e03115d3670707cc873a9965ba92 : hurdmalloc also needs the same fix * hurd/hurdmalloc.c (malloc_fork_prepare): Rename to _hurd_malloc_fork_prepare. (malloc_fork_parent): Rename to _hurd_malloc_fork_parent. (malloc_fork_child): Rename to _hurd_malloc_fork_child. (_hurd_fork_prepare_hook): Drop malloc_fork_prepare. (_hurd_fork_parent_hook): Drop malloc_fork_parent. (_hurd_fork_child_hook): Drop malloc_fork_child. * hurd/hurdmalloc.h (_hurd_malloc_fork_prepare, _hurd_malloc_fork_parent, _hurd_malloc_fork_child): Add declarations. * sysdeps/mach/hurd/fork.c (__fork): Call __malloc_fork_lock_parent after locking locks (notably hurd_dtable_lock). Call _hurd_malloc_fork_prepare after that. Call _hurd_malloc_fork_parent before __malloc_fork_unlock_parent and _hurd_malloc_fork_child before __malloc_fork_unlock_child.
2015-10-20Convert 113 more function definitions to prototype style (files with ↵Joseph Myers1-7/+3
assertions). This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.
