* Fix ttyslot namespace (bug 18547).Joseph Myers2015-06-172-17/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ttyslot (XPG4) calls the non-XPG4 functions endttyent, getttyent and setttyent, which in turn bring in references to fgets_unlocked and getttynam. This patch fixes this by making these functions into weak aliases and calling the __* names as needed. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18547] * misc/getttyent.c (getttynam): Rename to __getttynam and define as weak alias of __getttynam. Use prototype function definition. Call __setttyent, __getttyent and __endttyent instead of setttyent, getttyent and endttyent. (getttyent): Rename to __getttyent and define as weak alias of __getttyent. Call __setttyent instead of setttyent. Call __fgets_unlocked instead of fgets_unlocked. (setttyent): Rename to __setttyent and define as weak alias of __setttyent.

* Fix getpass fflush_unlocked namespace (bug 18540).Joseph Myers2015-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The getpass function (XPG3 / XPG4 / UNIX98) calls fflush_unlocked (not in any of those standards). This patch fixes this by making fflush_unlocked into a weak alias for __fflush_unlocked and calling __fflush_unlocked from getpass. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18540] * libio/iofflush.c [!_IO_MTSAFE_IO] (__fflush_unlocked): Define as strong alias of _IO_fflush.

* Fix sem_* tdelete, tfind, tsearch, twalk namespace (bug 18536).Joseph Myers2015-06-172-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sem_* functions bring in references to tdelete, tfind, tsearch and twalk. But the t* functions are XSI-shaded, while sem_* aren't. This patch fixes this by using __t* instead, exporting those functions from libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and using libc_hidden_* for the benefit of calls within libc. Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). libpthread gets changes from PLT reordering; addresses in libc change because of PLT / dynamic symbol table changes.

* Fix syslog dprintf namespace (bug 18534).Joseph Myers2015-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | syslog functions bring in references to dprintf, which wasn't added to POSIX until the 2008 edition and so isn't in various standards containing the syslog functions. This patch fixes this by making dprintf into a weak alias of __dprintf and using __dprintf as appropriate. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #18534] * stdio-common/dprintf.c (__dprintf): Use libc_hidden_def. (dprintf): Define as a weak alias of __dprintf, not a strong alias. * include/stdio.h (__dprintf): Declare.

* Fix vsyslog namespace (bug 18533).Joseph Myers2015-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | syslog functions (in POSIX) bring in the strong symbol vsyslog (not in POSIX). This patch fixes this by changing this symbol from a strong alias to a weak alias. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). (vsyslog becomes weak in the static libraries, which is what's needed; the particular macro sequence in use leaves it as strong in the shared libraries, hence those libraries being completely unchanged, but it doesn't generally matter whether symbols exported from the shared libraries are weak or strong.) [BZ #18533] * misc/syslog.c (vsyslog): Define as a weak alias of __vsyslog, not a strong alias. * conform/Makefile (test-xfail-XOPEN2K8/syslog.h/linknamespace): Remove variable.
* Fix syslog fputs_unlocked namespace (bug 18530).Joseph Myers2015-06-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | syslog (XSI POSIX) brings in references to fputs_unlocked (not POSIX). This patch fixes this by making fputs_unlocked into a weak alias for __fputs_unlocked and using __fputs_unlocked as needed. (No linknamespace test XFAILs are removed because there are other failures from syslog as well.) Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). Disassembly of installed stripped shared libraries is unchanged on x86_64; on x86, I see some small changes to instruction ordering and register choice, with no apparent reason for such changes to be related to this patch, but they also seem completely harmless with no change to code size. [BZ #18530] * libio/iofputs.c [!_IO_MTSAFE_IO] (__fputs_unlocked): Define as strong alias of _IO_fputs. Use libc_hidden_def. * libio/iofputs_u.c (fputs_unlocked): Rename to __fputs_unlocked and define as weak alias of __fputs_unlocked. Use libc_hidden_weak. * include/stdio.h (__fputs_unlocked): Declare. Use libc_hidden_proto. * misc/syslog.c (__vsyslog_chk): Call __fputs_unlocked instead of fputs_unlocked.
* Fix ecvt_r, fcvt_r namespace (bug 18522).Joseph Myers2015-06-121-2/+2
| | | | | | | | | | | | | | | | | | | | | The functions ecvt, fcvt and gcvt, in some standards, bring in references to ecvt_r and fcvt_r, which aren't in any of those standards. The calls are correctly to __ecvt_r and __fcvt_r, but then the names ecvt_r and fcvt_r are defined as strong aliases; this patch changes them to weak aliases. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18522] * misc/efgcvt_r.c [LONG_DOUBLE_COMPAT (libc, GLIBC_2_0) && !LONG_DOUBLE_CVT] (cvt_symbol): Use weak_alias instead of strong_alias.

* Fix open_memstream namespace (bug 18498).Joseph Myers2015-06-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | open_memstream is new in the 2008 edition of POSIX. However, the older functions getopt, closelog and fmtmsg all bring in references to it. This patch fixes this in the usual way, making open_memstream into a weak alias of __open_memstream and calling __open_memstream from the relevant places. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). 32-bit builds produce an XPASS for conform/POSIX/unistd.h/linknamespace after this patch (because the only cause of failure left there now is 64-bit specific); that will disappear once the 64-bit failure is resolved and the XFAIL removed at that time. [BZ #18498] * libio/memstream.c (open_memstream): Rename to __open_memstream and define as weak alias of __open_memstream. * include/stdio.h (__open_memstream): Declare. Use libc_hidden_proto.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of the (XSI POSIX) functions hsearch / hcreate / hdestroy uses hsearch_r / hcreate_r / hdestroy_r, which are not POSIX functions. This patch makes those into weak aliases for __*_r and uses those names for the calls within libc. Tested for x86_64 that the disassembly of installed shared libraries is unchanged by this patch. [BZ #17996] * include/search.h (hcreate_r): Don't use libc_hidden_proto. (hdestroy_r): Likewise. (hsearch_r): Likewise. (__hcreate_r): Declare and use libc_hidden_proto. (__hdestroy_r): Likewise.

* Fix incorrect mount table entry parsing in __getmntent_rVladimir A. Nazarenko2015-01-062-2/+26
| | | | | | | | | When mount entry contains only four fields and have more then one space or tab at the and, mp.mnt_freq and mp.mnt_passno will be set to some specific values as side effect from parsing of previus mount entry. It is because sscanf(""," %d %d ", &a, &b) returns -1, but this case is unprocessed. Values of mp.mnt_freq and mp.mnt_passno stays unchanged. This patch is attempt to fix described issue by removing trailing tabs and spaces.

* Fix fgets_unlocked namespace issues (bug 17664).Joseph Myers2014-12-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Avoid deprecated sigblock in misc/tst-pselect.c.Joseph Myers2014-11-271-2/+5
| | | | | | | | | | | | | | misc/tst-pselect.c uses the deprecated sigblock interface, resulting in "tst-pselect.c:42:3: warning: 'sigblock' is deprecated (declared at ../signal/signal.h:189) [-Wdeprecated-declarations]". The choice of sigblock rather than sigprocmask has nothing to do with what this test is testing, so this patch changes it to use sigprocmask to avoid the warning. Tested for x86_64. * misc/tst-pselect.c (do_test): Use sigprocmask instead of sigblock.
* Modify several tests to use test-skeleton.cArjun Shankar2014-11-055-10/+25

* Make __extern_always_inline usable on clang++ againSiddhesh Poyarekar2014-09-161-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix for BZ #17266 (884ddc5081278f488ef8cd49951f41cfdbb480ce) removed changes that had gone into cdefs.h to make __extern_always_inline usable with clang++. This patch adds back support for clang to detect if GNU inlining semantics are available, this time without breaking the gcc use case. The check put here is based on the earlier patch and assertion[1] that checking if __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ is defined is sufficient to determine that clang++ suports GNU inlining semantics. Tested with a simple program that builds with __extern_always_inline with the patch and fails compilation without it. #include <stdio.h> #include <sys/cdefs.h> extern void foo_alias (void) __asm ("foo"); __extern_always_inline void foo (void) { puts ("hi oh world!"); return foo_alias (); } void foo_alias (void) { puts ("hell oh world"); } int main () { foo (); } [1] https://sourceware.org/ml/libc-alpha/2012-12/msg00306.html [BZ #17266] * misc/sys/cdefs.h: Define __extern_always_inline for clang 4.2 and newer.
* Revert to defining __extern_inline only for gcc-4.3+ (BZ #17266)Siddhesh Poyarekar2014-09-161-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for only __GNUC_STDC_INLINE__ and __GNUC_GNU_INLINE__ may not be sufficient since those flags were added during initial support for C99 inlining semantics. There is also a problem with always defining __extern_inline and __extern_always_inline, since it enables inline wrapper functions even when GNU inlining semantics are not guaranteed. This, along with the possibility of such wrappers using redirection (btowc for example) could result in compiler generating an infinitely recusrive call to the function. In fact it was such a recursion that led to this code being written the way it was; see: https://bugzilla.redhat.com/show_bug.cgi?id=186410 The initial change was to fix bugs 14530 and 13741, but they can be resolved by checking if __fortify_function and/or __extern_always_inline are defined, as it has been done in this patch. In addition, I have audited uses of __extern_always_inline to make sure that none of the uses result in compilation errors. There is however a regression in this patch for llvm, since it reverts the llvm expectation that __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ definition imply proper extern inline semantics. 2014-09-16 Siddhesh Poyarekar <siddhesh@redhat.com> Jakub Jelinek <jakub@redhat.com> [BZ #17266] * libio/stdio.h: Check definition of __fortify_function instead of __extern_always_inline to include bits/stdio2.h. * math/bits/math-finite.h [__USE_XOPEN || __USE_ISOC99]: Also check if __extern_always_inline is defined. [__USE_MISC || __USE_XOPEN]: Likewise. [__USE_ISOC99] Likewise. * misc/sys/cdefs.h (__fortify_function): Define only if __extern_always_inline is defined.

* Use existing makefile variables for dependencies on glibc libraries.Joseph Myers2014-05-161-5/+1

In some places glibc's Makefiles use those variables when linking against the relevant libraries, but in other places they hardcode the location of the libraries in the build tree. This patch cleans up various places to use the variables that already exist (in the case of libm, replacing several duplicate definitions of a $(link-libm) variable in subdirectory Makefiles). (It's not necessarily exactly equivalent to what the existing code does - in particular, $(shared-thread-library) includes libpthread_nonshared, but is replacing places that just referred to libpthread.so. But I think that change is desirable on the general principle of linking things as close as possible to the way in which they would be linked with an installed library, unless there is a clear reason not to do so.) To support running tests with an installed copy of glibc without needing the full build tree from when that copy was built, I think it will be useful to use such variables more generally and systematically - every time the rules for building a test refer to some file from the build tree that's also installed by glibc, use a makefile variable so that the installed-testing case can point those variables to installed copies of the files. This patch just deals with straightforward cases where such variables already exist. It's quite possible some uses of $(shared-thread-library) should actually be a new $(thread-library) variable that's set appropriately in the --disable-shared case, if those uses would in fact work without shared libraries. I didn't change the status quo that those cases hardcode use of a shared library whether or not it's actually needed (but other uses such as $(libm) and $(libdl) would now get the static library if the shared library isn't built, when some previously hardcoded use of the shared library - if they actually need shared libraries, the test itself needs an enable-shared conditional anyway).

* Make tests consistently use *.out output files.Joseph Myers2014-03-071-3/+3

In the case of the iconv test test-iconvconfig, output is redirected where it wasn't before. In various places the "generated" variable is updated to reflect the revised test names; in iconvdata/Makefile a typo (mmtrace-tst-loading) is also fixed. resolv/Makefile sets both "generate" (which appears unused) and "generated". Bitrot in the settings of these variables could no doubt be fixed so that "make clean" after build and testing leaves results the same as after configure (and indeed the tests-special / xtests-special variables could be used to simplify things, by removing those files automatically rather than listing them manually in these variables), and "make distclean" leaves an empty build directory, but right now it appears various files don't get deleted. I think they are liable to continue to bitrot in the absence of routine testing that these targets actually work, given that building in the source directory isn't supported and that was the main use of such makefile targets.

* Enumerate tests with special rules in tests-special variable.Joseph Myers2014-03-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a revised and updated version of <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>. In order to generate overall summaries of the results of all tests in the glibc testsuite, we need to identify and concatenate the files with the results of individual tests. Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this. However, the normal glibc approach is explicit enumeration of the expected set of files with a given property, rather than all files matching some pattern like that. Furthermore, we would like to be able to mark tests as UNRESOLVED if the file with their results is for some reason missing, and in future we would like to be able to mark tests as UNSUPPORTED if they are disabled for a particular configuration (rather than simply having them missing from the list of tests as at present). Such handling of tests that were not run or did not record results requires an explicit enumeration of tests. For the tests following the default makefile rules, $(tests) (and $(xtests)) provides such an enumeration. Others, however, are added directly as dependencies of the "tests" and "xtests" makefile targets. This patch changes the makefiles to put them in variables tests-special and xtests-special, with appropriate dependencies on the tests listed there then being added centrally. Those variables are used in Rules and so need to be set before Rules is included in a subdirectory makefile, which is often earlier in the makefile than the dependencies were present before. We previously discussed the question of where to include Rules; see the question at <https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a discussion in <https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why Rules is included early rather than late in subdirectory makefiles. It was necessary to avoid an indirection through the check-abi target and get the check-abi-* targets for individual libraries into the tests-special variable. The intl/ test $(objpfx)tst-gettext.out, previously built only because of dependencies from other tests, was also added to tests-special for the same reason. The entries in tests-special are the full makefile targets, complete with $(objpfx) and .out. If a future change causes tests to be named consistently with a .out suffix, this can be changed to include just the path relative to $(objpfx), without .out. Tested x86_64, including that the same set of files is generated in the build directory by a build and testsuite run both before and after the patch (except for changes to the elf/tst-null-argv.debug.out.<number> file name), and a build with run-built-tests=no to verify there aren't any more obvious instances of the issue Marcus Shawcroft reported with a previous version in <https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>. * Makefile (tests): Change dependencies to ....

* Consistently include Makeconfig after defining subdir.Joseph Myers2014-02-261-2/+2

No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed.

The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

* Add error reporting (via errno) to getauxval().Brooks Moses2013-12-182-2/+5
| | | | | | | | | | | | [BZ 15846] As discussed in the recent thread on my $EXEC_ORIGIN patch and in BZ 15846, getauxval() presently has no unambiguous way of reporting an error condition. It currently returns zero on error, but this may also be a valid result for some auxv entries. As there is no clear invalid result for all current and future auxv entries, this patch sets errno (following a suggestion in the BZ entry). This version of the patch also adds documentation and tests for the value-not-found conditions in getauxval().

* Use __gnu_inline__ for __extern_always_inline in g++-4.2Richard Smith2013-05-011-8/+6
| | | | | | | | | | | | | Use the __gnu_inline__ attribute in _FORTIFY_SOURCE's __extern_always_inline macro whenever the compiler supports it. Previously this macro only included the __gnu_inline__ attribute in C++ mode for gcc >= 4.3. However, __gnu_inline__ semantics are always desired for the __extern_always_inline functions, and are available in g++ 4.2 (and some releases of g++ 4.1, and also in Clang, which claims to be g++ 4.2). This change stops g++-4.2 from emitting weak definitions for the fortify wrapper functions if they can't be inlined, and also improves Clang compatibility.
