2015-10-16Convert 703 function definitions to prototype style.Joseph Myers11-42/+13
This automatically-generated patch converts 703 function definitions in glibc from old-style K&R to prototype-style. This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

Adds bug-strcoll2 to the string tests, along with the generation of required locales.
2015-10-08strcoll: Remove incorrect STRDIFF-based optimization (Bug 18589).Carlos O'Donell2-37/+94
The optimization introduced in commit f13c2a8dff2329c6692a80176262ceaaf8a6f74e, causes regressions in sorting for languages that have digraphs that change sort order, like cs_CZ which sorts ch between h and i. My analysis shows the fast-forwarding optimization in STRCOLL advances through a digraph while possibly stopping in the middle which results in a subsequent skipping of the digraph and incorrect sorting. The optimization is incorrect as implemented and because of that I'm removing it for 2.23, and I will also commit this fix for 2.22 where it was originally introduced. This patch reverts the optimization, introduces a new bug-strcoll2.c regression test that tests both cs_CZ.UTF-8 and da_DK.ISO-8859-1 and ensures they sort one digraph each correctly. The optimization can't be applied without regressing this test. Checked on x86_64, bug-strcoll2.c fails without this patch and passes after. This will also get a fix on 2.22 which has the same bug.

2015-09-08Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).Joseph Myers1-1/+1
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway.

2015-06-02Use libc_hidden_proto / libc_hidden_def with __strnlen.Joseph Myers1-0/+1
Various code in glibc uses __strnlen instead of strnlen for namespace reasons. However, __strnlen does not use libc_hidden_proto / libc_hidden_def (as is normally done for any function defined and called within the same library, whether or not exported from the library and whatever namespace it is in), so the compiler does not know that those calls are to a function within libc. This patch uses libc_hidden_proto / libc_hidden_def with __strnlen. On x86_64, it makes no difference to the installed stripped shared libraries. On 32-bit x86, it causes __strnlen calls to go to the same place as strnlen calls (the fallback strnlen implementation), rather than through a PLT entry for the strnlen IFUNC; I'm not sure of the logic behind when calls from within libc should use IFUNCs versus when they should go direct to a particular function implementation, but clearly it doesn't make sense for strnlen and __strnlen to be handled differently in this regard. Tested for x86_64 and x86 (testsuite, and comparison of installed shared libraries as described above). * string/strnlen.c [!STRNLEN] (__strnlen): Use libc_hidden_def. * include/string.h (__strnlen): Use libc_hidden_proto. * sysdeps/aarch64/strnlen.S (__strnlen): Use libc_hidden_def. * sysdeps/i386/i686/multiarch/strnlen-c.c [SHARED] (libc_hidden_def): Define __GI___strnlen as well as __GI_strnlen. * sysdeps/powerpc/powerpc32/power4/multiarch/strnlen-power7.S (libc_hidden_def): Undefine and redefine. * sysdeps/powerpc/powerpc32/power4/multiarch/strnlen-ppc32.c [SHARED] (libc_hidden_def): Define __GI___strnlen as well as __GI_strnlen. * sysdeps/powerpc/powerpc32/power7/strnlen.S (__strnlen): Use libc_hidden_def. * sysdeps/tile/tilegx/strnlen.c (__strnlen): Likewise.
2015-05-22Fix pathconf basename namespace (bug 18444).Joseph Myers1-2/+4
pathconf (sysdeps/unix/sysv/linux/pathconf.c) uses basename. But pathconf is in POSIX back to 1990 while basename is only reserved with external linkage in those standards including XPG functions. This patch fixes this namespace issue in the usual way, renaming basename to __basename and making it into a weak alias. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

2015-01-13Fix memory handling in strxfrm_l [BZ #16009]Leonhard Holz1-94/+394
[Modified from the original email by Siddhesh Poyarekar] This patch solves bug #16009 by implementing an additional path in strxfrm that does not depend on caching the weight and rule indices. In detail the following changed: * The old main loop was factored out of strxfrm_l into the function do_xfrm_cached to be able to alternativly use the non-caching version do_xfrm. * strxfrm_l allocates a a fixed size array on the stack. If this is not sufficiant to store the weight and rule indices, the non-caching path is taken. As the cache size is not dependent on the input there can be no problems with integer overflows or stack allocations greater than __MAX_ALLOCA_CUTOFF. Note that malloc-ing is not possible because the definition of strxfrm does not allow an oom errorhandling. * The uncached path determines the weight and rule index for every char and for every pass again. * Passing all the locale data array by array resulted in very long parameter lists, so I introduced a structure that holds them. * Checking for zero src string has been moved a bit upwards, it is before the locale data initialization now. * To verify that the non-caching path works correct I added a test run to localedata/sort-test.sh & localedata/xfrm-test.c where all strings are patched up with spaces so that they are too large for the caching path.

gcc now warns when the arguments to memset may have been accidentally transposed (i.e. length set to zero instead of the byte), so we don't need that bit of the code in glibc headers anymore. Tested on x86_64. Coe generated by gcc 4.8 is identical with or without the patch. I also tested gcc master, which does not result in any new failures. It does fail quite a few FORTIFY_SOURCE tests, but those failures are not due to this patch.

Thus no defines of TEST_IFUNC are needed, and the *-ifunc.c tests that just define TEST_IFUNC and include other tests are also redundant, as is the code to remove $(tests-ifunc) and $(xtests-ifunc) conditionally from tests and xtests. This patch removes the useless defines and tests of TEST_IFUNC and the associated useless tests and makefile code. It thereby fixes a series of warnings "../string/test-string.h:21:0: warning: "TEST_IFUNC" redefined" where test-string.h defines TEST_IFUNC to empty, other files define it to 1 and this produces warnings. Tested for x86_64. * debug/test-stpcpy_chk-ifunc.c: Remove file. * debug/test-strcpy_chk-ifunc.c: Likewise. * wcsmbs/test-wcschr-ifunc.c: Likewise. * wcsmbs/test-wcscmp-ifunc.c: Likewise. * wcsmbs/test-wcscpy-ifunc.c: Likewise. * wcsmbs/test-wcslen-ifunc.c: Likewise. * wcsmbs/test-wcsrchr-ifunc.c: Likewise. * wcsmbs/test-wmemcmp-ifunc.c: Likewise. * Rules [$(multi-arch) = no] (tests): Do not filter out $(tests-ifunc). [$(multi-arch) = no] (xtests): Do not filter out $(xtests-ifunc). * debug/Makefile (tests-ifunc): Remove variable. (tests): Do not add $(tests-ifunc). * wcsmbs/Makefile (tests-ifunc): Remove variable. (tests): Do not add $(tests-ifunc). * benchtests/bench-string.h (TEST_IFUNC): Remove macro. [TEST_IFUNC]: Remove conditionals. * string/test-string.h (TEST_IFUNC): Remove macro. [TEST_IFUNC]: Remove conditionals.
2014-11-26Fix test-strchr.c warnings for wide string testing.Joseph Myers1-3/+5
string/test-strchr.c is used for both wide and narrow string testing, but produces a series of warnings for wide string testing because of hardcoded use of narrow characters in the function check1. This patch fixes that function to use macros abstracting away the wide / narrow string choice, adding a new such macro to handle the string and character constants. Tested for x86_64. * string/test-strchr.c [!WIDE] (L): New macro. [WIDE] (L): Likewise. (check1): Use CHAR instead of char. Use L on string and character constants.
