* Convert 231 sysdeps function definitions to prototype style.Joseph Myers2015-10-191-6/+2

For __aio_sigqueue and __gai_sigqueue I had to add internal_function to the definitions as noted by Florian in <https://sourceware.org/ml/libc-alpha/2015-10/msg00595.html> to keep the functions compiling on x86 after conversion to prototype definitions. Otherwise, the patch is automatically generated with all the same exclusions and caveats as in <https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> except that it's a patch for sysdeps files. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). Also tested for arm, mips64 and powerpc32 that installed stripped shared libraries are unchanged by the patch. * sysdeps/arm/backtrace.c (__backtrace): Convert to prototype-style function definition. * sysdeps/i386/backtrace.c (__backtrace): Likewise. * sysdeps/i386/ffs.c (__ffs): Likewise. * sysdeps/i386/i686/ffs.c (__ffs): Likewise. * sysdeps/ia64/nptl/pthread_spin_lock.c (pthread_spin_lock): Likewise. * sysdeps/ia64/nptl/pthread_spin_trylock.c (pthread_spin_trylock): Likewise. * sysdeps/ieee754/ldbl-128/e_log2l.c (__ieee754_log2l): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_log2l.c (__ieee754_log2l): Likewise. * sysdeps/m68k/ffs.c (__ffs): Likewise. * sysdeps/m68k/m680x0/fpu/e_acos.c (FUNC): Likewise. * sysdeps/m68k/m680x0/fpu/e_fmod.c (FUNC): Likewise. * sysdeps/mach/adjtime.c (__adjtime): Likewise. * sysdeps/mach/gettimeofday.c (__gettimeofday): Likewise. * sysdeps/mach/hurd/_exit.c (_exit): Likewise. * sysdeps/mach/hurd/access.c (__access): Likewise. * sysdeps/mach/hurd/adjtime.c (__adjtime): Likewise. * sysdeps/mach/hurd/chdir.c (__chdir): Likewise. * sysdeps/mach/hurd/chmod.c (__chmod): Likewise. * sysdeps/mach/hurd/chown.c (__chown): Likewise. * sysdeps/mach/hurd/cthreads.c (cthread_keycreate): Likewise.

* Fix getlogin_r namespace (bug 18527).Joseph Myers2015-06-121-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Various functions in XPG4 bring in references to getlogin_r, which is not in XPG4; this is also a bug for some older POSIX versions which aren't yet covered by the linknamespace tests. This patch fixes this by making getlogin_r into a weak alias for __getlogin_r and using __getlogin_r as needed. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18527] * login/getlogin_r.c (getlogin_r): Rename to __getlogin_r and define as weak alias of __getlogin_r. Use libc_hidden_weak. * sysdeps/mach/hurd/getlogin_r.c (getlogin_r): Likewise. * sysdeps/unix/getlogin_r.c (getlogin_r): Likewise. * sysdeps/unix/sysv/linux/getlogin_r.c (getlogin_r): Likewise. * include/unistd.h (__getlogin_r): Declare.

The old implementation uses fd 0 to determine the login TTY. This was needed because using /dev/tty it is not possible to deduce the login TTY. For some time now there is the pseudo-file /proc/self/loginuid which directly helps us to find the user. Prefer using this file. It also works if stdin is closed, redirected, or re-opened.
