* 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.
