Sat Sep 28 03:02:49 1996 Ulrich Drepper <drepper@cygnus.com> * dirent/Makefile (routines): Add readdir_r. * dirent/readdir_r.c: New file. Wrapper around readdir.c. * dirent/dirent.h: Add prototype for readdir_r. * misc/hsearch_r.c (ENTRY): Make field `used' of type `unsigned int' to prevent warnings. * sysdeps/unix/sysv/linux/getsysstats.c (get_proc_path): Initialize `result'. Sat Sep 28 01:16:42 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/strsep.c: Rename to __strsep and make strsep weak alias. * string/string.h: Add prototype for __strsep. * misc/mntent_r.c: Use __strsep instead of strsep to keep namespace clean. * sysdeps/stub/nanosleep.c: Rename to __libc_nanosleep and make __nanosleep and nanosleep weak aliases. * sysdeps/unix/sysv/linux/syscalls.list: Add __nanosleep as weak alias. * sysdeps/unix/sysv/linux/sleep.c: Call __nanosleep instead of nanosleep to keep namespace clean. * sysdeps/posix/ttyname.c (ttyname): Add cast to prevent warning. * sysdeps/posix/ttyname_r.c (ttyname_r): Likewise. * sysdeps/posix/getcwd.c (__getcwd): Likewise. * sysdeps/unix/nlist.c: Use ISO C definition since we don't always have prototype. * login/Makefile (headers): Add pty.h. * login/pty.h: New file. * sysdeps/generic/pty.h: Include <pty.h>. * login/pututline_r.c: Add cast to prevent warning. * gmon/gmon.c: Add prototype for __profile_frequency. (monstartup): Add cast to prevent warning. * sysdeps/generic/prof-freq.c: Change to use ISO C style definition. * locale/programs/ld-time.c (time_output): Write `era' information in correct order. Sat Sep 28 00:11:08 1996 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/syscalls.list: Add weak alias `adjtimex'. Set caller for mlock, mlockall, mremap, munlock, and munlockall to EXTRA. Reported by Matthias Urlichs <smurf@smurf.noris.de>. 1996-09-27 Paul Eggert <eggert@twinsun.com> * strftime.c (strftime): Output incomplete formats like %E at end of string. 1996-09-27 Paul Eggert <eggert@twinsun.com> * strftime.c (strftime): Add support for %EC and %Ey. Fix support for %EY. This uses the new _nl_get_era_entry function. Fri Sep 27 14:12:27 1996 Ulrich Drepper <drepper@cygnus.com> Security related patch by Elliot Lee <sopwith@redhat.com> and David Holland <dholland@eecs.harvard.edu>. * inet/rexec.c (rexec): Increase size of `num' array from 8 to 32. * inet/ruserpass.c (ruserpass): Don't allow $HOME envvar to not exist. * sysdeps/generic/getenv.c (__secure_getenv): New function. Return NULL when programs runs with SUID or SGID enabled. * sysdeps/stub/getenv.c: Make __secure_getenv an alias of getenv. * stdlib/stdlib.h: Add prototype for __secure_getenv. * locale/setlocale.c: Use __secure_getenv. * resolv/res_init.c: Likewise. * resolv/res_query.c: Likewise. * inet/ruserpass.c: Likewise. * sysdeps/posix/tempname.c: Likewise. * malloc/mtrace.c: Likewise. * catgets/catgets.c: Likewise. Make temporary file handling functions reentrant. * stdio-common/tmpnam.c: Rewrite to have own buffer to write result to. The called __stdio_gen_tempname function must be thread safe. * stdio-common/tmpnam_r.c: New file. * stdio/stdio.h: Add prototype for `tmpnam_r'. Change prototype for __stdio_gen_tempname. * stdio/libio.h: Likewise. * sysdeps/posix/tempname.c: Add new parameters and use them instead of static buffer. Don't reset `indeces' when PID changed between calls. Don't fail for long running programs when index counter once reached the limit. * sysdeps/stub/tempname.c: Likewise. * stdio-common/tempnam.c: Provide local buffer as extra argument to __stdio_gen_tempname. This makes this function reentrant. * stdio-common/tmpfile.c: Likewise. * stdio-common/temptest.c: Provide extra argument to __stdio_gen_tempname. * manual/filesys.texi: Describe tmpnam_r and add comments about reentrancy of the functions. * inet/rcmd.c: Fixed address length handling. * sysdeps/posix/mk-stdiolim.c: Count final \0 byte in L_tmpnam value. * time/strftime.c: Remove unused variables alt_digits and end_alt_digits. * sysdeps/unix/sysv/linux/sys/sysinfo.h: Correct prototype names for get_nprocs and get_nprocs_conf. * sysdeps/generic/sys/sysinfo.h: Likewise. * stdlib/test-canon.c: Finally do the right fix. * misc/Makefile: Only compile force-wrapper when compiling reentrant libc.
