* Fix x86_64 memrchr namespace (bug 17719).Joseph Myers2014-12-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | On x86_64, memrchr (not a standard function) is defined as a strong symbol, instead of a weak alias of __memrchr as on other architectures. This results in linknamespace test failures from the use of __memrchr from dirname. (Not a conformance issue because of the mem* reservation, but contrary to glibc conventions.) This patch makes x86_64 follow other architectures by defining memrchr as a weak alias. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17719] * sysdeps/x86_64/memrchr.S (memrchr): Rename to __memrchr and define as weak alias of __memrchr. (__memrchr): Do not define as strong alias of memrchr. * conform/Makefile (test-xfail-XPG4/libgen.h/linknamespace): Remove variable. (test-xfail-UNIX98/libgen.h/linknamespace): Likewise.

* Fix resolver if_* namespace (bug 17717).Joseph Myers2014-12-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolver code, brought in by pthreads (at least), uses if_* interfaces that weren't in POSIX before 2001, resulting in linknamespace failures. This patch changes those interfaces to be weak aliases of __if_* and makes the resolver use __if_* directly. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch).

* intl: Merge with gettext version 0.19.3Will Newton2014-12-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch merges the latest release of gettext into the intl subdirectory. The initial motivation was to include the plural.y changes which enable building with bison 3.0, but the majority of the other changes are merely cosmetic so it seemed like merging the whole directory was simpler than trying to take it piecemeal. The merge was done by copying across the latext gettext code and adding in a few small glibc changes that have been added over the years that seemed beneficial, as well as a couple of small build fixes that should be merged back to gettext. I also reverted the gettext commit: commit 279b57fc367251666f00e8e2b599b83703451afb Author: Bruno Haible <bruno@clisp.org> Date: Fri Jun 14 12:03:49 2002 +0000 Make absolute pathnames inside $LANGUAGE work. As it caused localedata/tst-setlocale3 to fail and it wasn't clear that glibc wanted that behaviour. The merge has dropped many uses of __glibc_likely/unlikely. This is intentional given that it eases merging. It seems to me that the cost of continually rewriting these lines when merging and the risk of adding bugs when doing so outweighs the benefits of using these macros when code is shared with another project. Tested with make check on x86_64. ChangeLog: 2014-12-11 Will Newton <will.newton@linaro.org> Merge gettext 0.19.3 into intl/.

* Fix strftime wcschr namespace (bug 17634).Joseph Myers2014-12-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of strftime, a C90 function, ends up bringing in wcschr, which is not a C90 function. Although not a conformance bug (C90 reserves wcs*), this is still contrary to glibc practice of avoiding relying on those reservations; this patch arranges for the internal uses to use __wcschr instead, with wcschr being a weak alias. This is more complicated than some such patches because of the various IFUNC definitions of wcschr (which include code redefining libc_hidden_def in a way that involves creating __GI_wcschr manually and so also needs to create __GI___wcschr after the change of internal uses to use __wcschr).

* manual: Remove incorrect claim that qsort() can be stabilizedAnders Kaseorg2014-12-101-6/+6
| | | | | | | | | | | | Under certain conditions on the size of the array and its items, qsort() may fall back to an in-place quicksort if it cannot allocate memory for a temporary array with malloc(). This algorithm is not a stable sort even if the comparison function is written in the described manner. Fixes #10672. Signed-off-by: Anders Kaseorg <andersk@mit.edu>

* Use -Werror by default, add --disable-werror.Joseph Myers2014-12-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed starting at <https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this patch makes the glibc build use -Werror by default to avoid accidentally adding new warnings to the build. The configure option --disable-werror can be used to disable this. -Wno-error=undef is temporarily used because the build isn't clean regarding -Wundef warnings. The idea is that once the remaining -Wundef warnings have been cleaned up (in at least one configuration), -Wno-error=undef will be removed. I get a clean build and test on x86_64 (GCC 4.9 branch) with this patch. The expectation is that this may well break the build for some other configurations, and people seeing such breakage should make appropriate fixes to fix or suppress the warnings for their configurations. In some cases that may involve using pragmas as the right fix (I think that will be right for the -Wno-inline issue for MIPS I referred to in <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for example), in some cases -Wno-error in sysdeps makefiles (__restore_rt in MIPS sigaction, for example), in some cases substantive fixes for the warnings. Note that if, with a view to listing all the warnings then fixing them all, you just look for "warning:" in output from building and testing with --disable-werror, you'll see lots of warnings from the linker about functions such as tmpnam. Those warnings can be ignored - only compiler warnings are relevant to -Werror, not linker warnings. * configure.ac (--disable-werror): New configure option. (enable_werror): New AC_SUBST. * configure: Regenerated. * config.make.in (enable-werror): New variable. * Makeconfig [$(enable-werror) = yes] (+gccwarn): Add -Werror -Wno-error=undef.

* Fix pthreads getrlimit, gettimeofday namespace (bug 17682).Joseph Myers2014-12-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some pthreads functions use getrlimit and gettimeofday, but these functions are XSI, not base POSIX; this is a namespace issue for dynamic linking as well as static linking. This patch makes them use __getrlimit and __gettimeofday instead - the former needed to be newly exported from libc.so at GLIBC_PRIVATE (and so now needs libc_hidden_proto / libc_hidden_def), the latter was already exported. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17682] * resource/Versions (libc): Add __getrlimit at GLIBC_PRIVATE. * resource/getrlimit.c (__getrlimit): Use libc_hidden_def. * sysdeps/mach/hurd/getrlimit.c (__getrlimit): Likewise. * include/sys/resource.h (__getrlimit): Use libc_hidden_proto. * nptl/nptl-init.c (__pthread_initialize_minimal_internal): Use __getrlimit instead of getrlimit. * nptl/pthread_cond_timedwait.c (__pthread_cond_timedwait): Use __gettimeofday instead of gettimeofday. * nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock): Likewise. * nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock): Likewise. * sysdeps/pthread/aio_misc.c (handle_fildes_io): Likewise. * conform/Makefile (test-xfail-POSIX2008/aio.h/linknamespace): Remove variable.

* Reset cached offset when reading to end of stream (BZ #17653)Siddhesh Poyarekar2014-12-041-1/+1
| | | | | | POSIX allows applications to switch file handles when a read results in an end of file. Unset the cached offset at this point so that it is queried again.
* ftell: seek to end only when there are unflushed bytes (BZ #17647)Siddhesh Poyarekar2014-12-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently we seek to end of file if there are unflushed writes or the stream is in write mode, to get the current offset for writing in append mode, which is the end of file. The latter case (i.e. stream is in write mode, but no unflushed writes) is unnecessary since it will only happen when the stream has just been flushed, in which case the recorded offset ought to be reliable. Removing that case lets ftell give the correct offset when it follows an ftruncate. The latter truncates the file, but does not change the file position, due to which it is permissible to call ftell without an intervening fseek call. Tested on x86_64 to verify that the added test case fails without the patch and succeeds with it, and that there are no additional regressions due to it. [BZ #17647] * libio/fileops.c (do_ftell): Seek only when there are unflushed writes. * libio/wfileops.c (do_ftell_wide): Likewise. * libio/tst-ftell-active-handler.c (do_ftruncate_test): New test case.

* Fix getifaddrs, freeifaddrs namespace (bug 17668).Joseph Myers2014-12-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various objects in glibc bring in ifaddrs.o (via references to __netlink_*) and thereby getifaddrs and freeifaddrs, which are not part of any standard supported by glibc. These should be weak aliases of __getifaddrs and __freeifaddrs; this patch makes them so. (The path by which these functions are brought in is Linux-specific, but it seems less confusing to make all versions of these functions weak aliases rather than only the Linux-specific versions that definitely need it.) Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17668] * inet/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define as weak alias of __getifaddrs. Use libc_hidden_weak.

* Remove excess declarations from unistd.h for XPG3/XPG4 (bug 17665).Joseph Myers2014-12-021-1/+1
| | | | | | | | | | | | | | | | | | For XPG3/XPG4 (defined __USE_XOPEN && !defined __USE_UNIX98), unistd.h declares many functions that should only be declared for __USE_MISC (none of them are in XPG3/XPG4): sethostname sethostid getdomainname setdomainname vhangup revoke profil acct getusershell endusershell setusershell daemon. The whole block with the [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)] conditional contains only functions that are not in XPG3/XPG4, so this patch simply changes the conditional. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch). [BZ #17665] * posix/unistd.h [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)]: Change conditional to [__USE_MISC].
* Fix fgets_unlocked namespace issues (bug 17664).Joseph Myers2014-12-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various POSIX functions bring in res_init.o, res_hconf.o or mntent_r.o, which use fgets_unlocked, which is not a POSIX function. This patch arranges for them to use __fgets_unlocked instead. (The IS_IN (libc) conditional in rec_hconf.c is needed because that file is also used in nscd.) Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch except for an assertion line number). Note that most of the linknamespace tests that failed because of fgets_unlocked from the resolver also fail because of other symbols brought in by the resolver, so the number of XFAILs this removes is limited. Also note that fgets_unlocked failures for unistd.h for XPG3/XPG4 showed up that actually unistd.h is declaring too much for XPG3/XPG4 (bug 17665) - there is no actual need to make getusershell.c use __fgets_unlocked (at least as regards formal standards are concerned; maybe it should still change for namespace-cleanness of _DEFAULT_SOURCE) because the functions there aren't actually in any of the supported standards; the correct fix for those failures will be to stop the *usershell* functions appearing in unistd.h for XPG3/XPG4. [BZ #17664] * misc/mntent_r.c (__getmntent_r): Use __fgets_unlocked instead of fgets_unlocked. * resolv/res_hconf.c [IS_IN (libc)] (fgets_unlocked): Define to __fgets_unlocked. * resolv/res_init.c (__res_vinit): Use __fgets_unlocked instead of fgets_unlocked. * conform/Makefile (test-xfail-XPG4/sys/statvfs.h/linknamespace): Remove variable.

* CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.Carlos O'Donell2014-11-191-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of "$((... ``))" where "..." can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD in exec_comm(), the only place that can execute a shell. All other checks for WRDE_NOCMD are superfluous and removed. We expand the testsuite and add 3 new regression tests of roughly the same form but with a couple of nested levels. On top of the 3 new tests we add fork validation to the WRDE_NOCMD testing. If any forks are detected during the execution of a wordexp() call with WRDE_NOCMD, the test is marked as failed. This is slightly heuristic since vfork might be used in the future, but it provides a higher level of assurance that no shells were executed as part of command substitution with WRDE_NOCMD in effect. In addition it doesn't require libpthread or libdl, instead we use the public implementation namespace function __register_atfork (already part of the public ABI for libpthread). Tested on x86_64 with no regressions.

* Require GCC 4.6 or later to build glibc.Joseph Myers2014-11-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | As discussed in the thread starting at <https://sourceware.org/ml/libc-alpha/2014-10/msg00792.html>, and continuing into November, this patch increases the minimum GCC version for building glibc to 4.6 (there seemed to be no clear consensus for 4.7). In particular, this allows us to use #pragma GCC diagnostic for fine-grained warning control with -Werror (subject to establishing a suitable policy for that use). The documentation has a statement, as requested, about the most recent GCC version tested for building glibc, and I've updated <https://sourceware.org/glibc/wiki/Release> to refer to updating that statement. A NEWS entry is added for this change, although previous such changes didn't get them. Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by this patch). * configure.ac (libc_cv_compiler_ok): Require GCC 4.6 or later. * configure: Regenerated. * manual/install.texi (Tools for Compilation): Document a requirement of GCC 4.6 or later and that GCC 4.9 is the newest compiler verified to work. * INSTALL: Regenerated.
* Fix strtoll / strtoull namespace for 32-bit (bug 17594).Joseph Myers2014-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 32-bit platforms, strtoll and strtoull are strong symbols in libc, but they are not in ISO C90, and are brought in by references to __strtoll_internal / __strtoull_internal from scanf. (For 64-bit platforms, they are properly weak.) This patch makes them weak for 32-bit (it has a side-effect of making other symbols weak that don't need to be weak, such as strtol, but that's harmless). Tested for x86 (testsuite, and that the disassembly of installed shared libraries is unchanged by the patch). This fixes all 120 unXFAILed FAILs of the new linknamespace tests seen for x86 (in fact, there are now seven XPASSes of those tests for x86 XPASS: conform/POSIX2008/fcntl.h/linknamespace XPASS: conform/UNIX98/libgen.h/linknamespace XPASS: conform/XOPEN2K/fcntl.h/linknamespace XPASS: conform/XOPEN2K/libgen.h/linknamespace XPASS: conform/XOPEN2K8/fcntl.h/linknamespace XPASS: conform/XOPEN2K8/libgen.h/linknamespace XPASS: conform/XPG4/libgen.h/linknamespace so suggesting that the failures seen for those on x86_64 are in some way architecture-specific or 64-bit-specific).

* Fix locale memmem namespace (bug 17585).Joseph Myers2014-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Locale code, brought in by ISO C functions, calls memmem, which is not an ISO C function. This isn't an ISO C conformance bug, because all mem* names are reserved, but glibc practice is not to rely on that reservation (thus, memmem is only declared in string.h if __USE_GNU even though ISO C would allow it to be declared unconditionally, for example). This patch changes that code to use __memmem. Note: there are uses of memmem elsewhere in glibc that I didn't change, although it may turn out some of those also need to use __memmem. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17585] * string/memmem.c [!_LIBC] (__memmem): Define to memmem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __get_nprocs is called from malloc code, but calls fgets_unlocked, which is not an ISO C or POSIX function. This patch fixes it to call a new __fgets_unlocked name instead. Note: there are various other uses of fgets_unlocked in glibc's libraries, and I haven't yet investigated which others might also be problematic (called directly or indirectly from standard functions) and so need to change to use __fgets_unlocked.

* Fix stpcpy / mempcpy namespace (bug 17573).Joseph Myers2014-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various glibc functions call __stpcpy and __mempcpy for namespace reasons instead of plain stpcpy and mempcpy. But __stpcpy and __mempcpy are macros that call __builtin_stpcpy and __builtin_mempcpy, and unless GCC optimizes the calls, they end up calling the C functions stpcpy and mempcpy. For calls from within shared libc, libc_hidden_builtin_proto ensures that calls to those C functions are in turn mapped to call __GI_stpcpy and __GI_mempcpy. However, for static libc, and for calls from shared libraries other than libc, the ELF symbols stpcpy and mempcpy end up getting called, breaking the ISO C namespace (in the case of stpcpy) or glibc conventions about not relying on the "future library directions" reservations (in the case of mempcpy). This patch fixes this by adding declarations of these functions to include/string.h, under an appropriate condition, with __asm__ used to change the assembler name used for calls (the mempcpy case was previously discussed, and the approach for the fix is as I suggested in <https://sourceware.org/ml/libc-alpha/2013-02/msg00063.html>). Tested for x86_64 with the testsuite; also checked that dcigettext.o (an example previously noted of undesired calls to stpcpy and mempcpy) now calls __stpcpy and __mempcpy instead, as do non-libc shared libraries (__stpcpy and __mempcpy were already exported from shared libc). Disassembly of installed shared libraries isn't easy to compare because of reordered PLT entries resulting from the change in functions called (libnsl, libnss_compat, libnss_dns, libnss_files, libnss_hesiod, libnss_nis, libnss_nisplus, libpthread, librt all have such changes). [BZ #17573] * include/string.h [NOT_IN_libc || !SHARED] (mempcpy): Declare with asm name __mempcpy. [NOT_IN_libc || !SHARED] (stpcpy): Declare with asm name __stpcpy.
* Fix x86_64 rawmemchr namespace (bug 17572).Joseph Myers2014-11-121-1/+1
| | | | | | | | | | | | | | | | rawmemchr is not an ISO C function, but __rawmemchr is called from ISO C functions, so rawmemchr should be a weak alias. On most architecture it is, but x86_64 defines the function as rawmemchr with __rawmemchr as a strong alias. This patch makes x86_64 follow the same arrangements as other architectures. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17572] * sysdeps/x86_64/rawmemchr.S (rawmemchr): Rename to __rawmemchr and define as weak alias of __rawmemchr. (__rawmemchr): Do not define as strong alias of rawmemchr.
* Fix qsort_r namespace (bug 17571).Joseph Myers2014-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | qsort_r is defined in the same file as qsort, but is not an ISO C function, so should be a weak alias for __qsort_r. The uses in getaddrinfo should also call __qsort_r, since getaddrinfo is a POSIX function and qsort_r isn't. This patch implements this. Because nscd uses the getaddrinfo sources outside libc, as do the tst-rfc3484 tests, a #define of __qsort_r to qsort_r is added there alongside the similar defines for other libc-internal symbols used in getaddrinfo. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17571] * stdlib/msort.c (qsort_r): Rename to __qsort_r and define as weak alias of __qsort_r.

* Fix malloc_info namespace (bug 17570).Joseph Myers2014-11-121-1/+1
| | | | | | | | | | | | | malloc_info is defined in the same file as malloc and free, but is not an ISO C function, so should be a weak symbol. This patch makes it so. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __getcwd is called from dcigettext.o (brought in by various ISO C functionality), but calls rewinddir, which is not an ISO C function. This patch makes __getcwd call __rewinddir instead and makes rewinddir a weak alias for __rewinddir. Since getcwd.c is shared with gnulib (albeit not merged in either direction for a long time, and omitted from gnulib's config/srclist.txt list of shared files) I put in a #ifndef _LIBC define of __rewinddir to rewinddir, although a future merged version of getcwd could end up looking significantly different.

Note: there are various uses of fileno elsewhere in glibc that I didn't change, although it may turn out that some of those also need to use __fileno. Tested for x86_64 with the glibc testsuite.
