2018-03-02Fix powerpc ifunc-sel.h build for -Os.Joseph Myers
Compiling the testsuite for powerpc (multi-arch configurations) with -Os with GCC 7 fails with: In file included from ifuncmod1.c:7:0, from ifuncdep1.c:3: ../sysdeps/powerpc/ifunc-sel.h: In function 'ifunc_sel': ../sysdeps/powerpc/ifunc-sel.h:12:3: error: asm operand 2 probably doesn't match constraints [-Werror] __asm__ ("mflr 12\n\t" ^~~~~~~ ../sysdeps/powerpc/ifunc-sel.h:12:3: error: asm operand 3 probably doesn't match constraints [-Werror] ../sysdeps/powerpc/ifunc-sel.h:12:3: error: asm operand 4 probably doesn't match constraints [-Werror] ../sysdeps/powerpc/ifunc-sel.h:12:3: error: impossible constraint in 'asm' The "i" constraints on function pointers require the function call to be inlined so the compiler can see the constant function pointer arguments passed to the asm. This patch marks the relevant functions as always_inline accordingly. Tested that this fixes the -Os testsuite build for powerpc-linux-gnu-power4, powerpc64-linux-gnu, powerpc64le-linux-gnu with build-many-glibcs.py. * sysdeps/powerpc/ifunc-sel.h (ifunc_sel): Make always_inline.

2018-03-01[BZ #22342] Fix netgroup cache keys.DJ Delorie
Unlike other nscd caches, the netgroup cache contains two types of records - those for "iterate through a netgroup" (i.e. setnetgrent()) and those for "is this user in this netgroup" (i.e. innetgr()), i.e. full and partial records. The timeout code assumes these records have the same key for the group name, so that the collection of records that is "this netgroup" can be expired as a unit. However, the keys are not the same, as the in-netgroup key is generated by nscd rather than being passed to it from elsewhere, and is generated without the trailing NUL. All other keys have the trailing NUL, and as noted in the linked BZ, debug statements confirm that two keys for the same netgroup are added to the cache with two different lengths. The result of this is that as records in the cache expire, the purge code only cleans out one of the two types of entries, resulting in stale, possibly incorrect, and possibly inconsistent cache data. The patch simply includes the existing NUL in the computation for the key length ('key' points to the char after the NUL, and 'group' to the first char of the group, so 'key-group' includes the first char to the NUL, inclusive). [BZ #22342] * nscd/netgroupcache.c (addinnetgrX): Include trailing NUL in key value. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2018-03-01nptl_db: Remove stale `match_pid' parameter from `iterate_thread_list'Maciej W. Rozycki
Complement commit c579f48edba8 ("Remove cached PID/TID in clone") and remove the `match_pid' parameter not used by `iterate_thread_list' any longer. Update call sites accordingly. * nptl_db/td_ta_thr_iter.c (iterate_thread_list): Remove `match_pid' parameter. (td_ta_thr_iter): Update accordingly.

2018-03-01nptl: Drop libpthread_nonshared.a from libpthread.soFlorian Weimer
Fixes commit bd60ce86520b781ca24b99b2555e2ad389bbfeaa (nptl: Move pthread_atfork to libc_nonshared.a).
2018-03-01nptl: Move pthread_atfork to libc_nonshared.aFlorian Weimer
libpthread_nonshared.a is unused after this, so remove it from the build. There is no ABI impact because pthread_atfork was implemented using __register_atfork in libc even before this change. pthread_atfork has to be a weak alias because pthread_* names are not reserved in libc.

2018-02-28Fix i386 fenv_private.h float128 for 32-bit --with-fpmath=sse (bug 22902).Joseph Myers
As discussed in bug 22902, the i386 fenv_private.h implementation has problems for float128 for the case of 32-bit glibc built with libgcc from GCC configured using --with-fpmath=sse. The optimized floating-point state handling in fenv_private.h needs to know which floating-point state - x87 or SSE - is used for each floating-point type, so that only one state needs updating / testing for libm code using that state internally. On 32-bit x86, the x87 rounding mode is always used for float128, but the x87 exception flags are only used when libgcc is built using x87 floating-point arithmetic; if libgcc is built for SSE arithmetic, the SSE exception flags are used. The choice of arithmetic with which libgcc is built is independent of that with which glibc is built. Thus, since glibc cannot tell the choice used in libgcc, the default implementations of libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128 (which use the <fenv.h> functions, thus using both x87 and SSE state on processors that have both) need to be used; this patch updates the code accordingly. Tested for 32-bit x86; HJ reports testing in the --with-fpmath=sse case. [BZ #22902] * sysdeps/i386/fpu/fenv_private.h [!__x86_64__] (libc_feholdexcept_setroundf128): New macro. [!__x86_64__] (libc_feupdateenv_testf128): Likewise.
2018-02-28Use libc_hidden_* for strtoumax (bug 15105).Joseph Myers
On sparc, localplt test failures appear when building with -Os because of a call to strtoumax from sysdeps/unix/sysv/linux/sparc/sparc64/get_clockfreq.c, and strtoumax is not inlined when building with -Os. This patch fixes those failures by using libc_hidden_proto and libc_hidden_def for strtoumax. Tested with build-many-glibcs.py for sparc64-linux-gnu-disable-multi-arch, sparc64-linux-gnu, sparcv9-linux-gnu-disable-multi-arch, sparcv9-linux-gnu that this fixes that test failure with -Os. [BZ #15105] * sysdeps/wordsize-32/strtoumax.c (strtoumax): Use libc_hidden_def. * sysdeps/wordsize-64/strtoumax.c (strtoumax): Likewise. * include/inttypes.h: New file.
2018-02-27Fix two more -Os strcoll / wcscoll build failures.Joseph Myers
Continuing fixes for -Os build issues shown with build-many-glibcs.py, this patch adds uses of DIAG_* to disable -Wmaybe-uninitialized in two more places where code inlined from strcoll / wcscoll is wrongly diagnosed as possibly using uninitialized structure fields. (All these warnings in different places for these functions are I think essentially the same bug.) Tested with build-many-glibcs.py for alpha-linux-gnu and mips-linux-gnu that this fixes the -Os build failures for those configurations with GCC 7. * locale/weightwc.h (findidx): Ignore -Wmaybe-uninitialized for -Os in two more places.
2018-02-27Remove the lines from cmn_TW.UTF-8.in which cannot work at the moment.Mike FABIAN
See this bug https://sourceware.org/bugzilla/show_bug.cgi?id=22898 These lines don’t yet work because of a glibc bug, not because of problems in the locale data. No matter what sorting rules one uses, these characters cannot be sorted at all at the moment. As soon as that bug is fixed, these lines should be added back to the test file. * localedata/cmn_TW.UTF-8.in: Remove the lines which cannot be sorted correctly at the moment because of a bug.

2018-02-27Fix test cases tst-fnmatch and tst-regexloc for the new iso14651_t1_common file.Mike FABIAN
See: http://pubs.opengroup.org/onlinepubs/7908799/xbd/re.html > A range expression represents the set of collating elements that fall > between two elements in the current collation sequence, > inclusively. It is expressed as the starting point and the ending > point separated by a hyphen (-). > > Range expressions must not be used in portable applications because > their behaviour is dependent on the collating sequence. Ranges will be > treated according to the current collating sequence, and include such > characters that fall within the range based on that collating > sequence, regardless of character values. This, however, means that > the interpretation will differ depending on collating sequence. If, > for instance, one collating sequence defines ä as a variant of a, > while another defines it as a letter following z, then the expression > [ä-z] is valid in the first language and invalid in the second. Therefore, using [a-z] does not make much sense except in the C/POSIX locale. The new iso14651_t1_common lists upper case and lower case Latin characters in a different order than the old one which causes surprising results for example in the de_DE locale: [a-z] now includes A because A comes after a in iso14651_t1_common but does not include Z because that comes after z in iso14651_t1_common. * posix/tst-fnmatch.input: Fix results for range expressions for non C locales. * posix/tst-regexloc.c: Do not use a range expression for de_DE.ISO-8859-1 locale.

are ignorable on all 4 levels Entries for characters which have “IGNORE” on all 4 levels like: <U0001> IGNORE;IGNORE;IGNORE;IGNORE % START OF HEADING (in ISO 6429) are changed into: <U0001> IGNORE;IGNORE;IGNORE;<U0001> % START OF HEADING (in ISO 6429) i.e. putting the code point of the character into the fourth level instead of “IGNORE”. Without that change, all such characters would compare equal which would make a wcscoll test case fail. It is better to have a clearly defined sort order even for characters like this so it is good to use the code point as a tie-break. * localedata/locales/iso14651_t1_common: Use the code point of a character in the fourth collation level instead of IGNORE for all entries which have IGNORE on all 4 levels.

2018-02-26Fix another -Os strcoll build issue.Joseph Myers
While there are now clean -Os build and test results on x86_64 (given my patch <https://sourceware.org/ml/libc-alpha/2018-02/msg00602.html>, pending review), testing with -Os with build-many-glibcs.py shows the build is still failing with -Os everywhere except for x86_64, x86 and s390x. There are a variety of different build failures, but the most common seem to be in strcoll / wcscoll, similar to existing such cases where DIAG_* are used to disable -Wmaybe-uninitialized. There are various different failures even within those functions. This patch fixes one particular case that seems quite common, where the warning appears at the declarations of seq1 and seq2. Tested with build-many-glibcs.py that this fixes the -Os build for aarch64-linux-gnu with GCC 7. * string/strcoll_l.c: Include <libc-diag.h>.

2018-02-23Define GEN_AS_CONST_HEADERS when generating header files [BZ #22792]H.J. Lu
Glibc build generates header files to define constants from special .sym files. If a .sym file includes the same header file which it generates, it leads to circular dependency which may lead to build hang on a many-core machine. Define GEN_AS_CONST_HEADERS when generating header files to avoid circular dependency. <tcb-offsets.h> is needed for i686 and it isn't needed for x86-64 at least since glibc 2.23. Tested on i686 and x86-64. [BZ #22792] * Makerules ($(common-objpfx)%.h): Pass -DGEN_AS_CONST_HEADERS to $(CC). * sysdeps/unix/sysv/linux/i386/lowlevellock.h: Include <tcb-offsets.h> only if GEN_AS_CONST_HEADERS isn't defined. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.h: Don't include <tcb-offsets.h>.
2018-02-23Use libc_hidden_* for tolower, toupper (bug 15105).Joseph Myers
Continuing the fixes for localplt test failures with -Os arising from functions not being inlined in that case, this patch fixes such failures for tolower and toupper by using libc_hidden_proto and libc_hidden_def. Tested for x86_64 (both that it removes this particular localplt failure for -Os, and that the testsuite continues to pass without -Os). 2018-02-22 Joseph Myers <joseph@codesourcery.com> [BZ #15105] * ctype/ctype.c (tolower): Use libc_hidden_def. (toupper): Likewise. * include/ctype.h [!_ISOMAC] (tolower): Use libc_hidden_proto. [!_ISOMAC] (toupper): Likewise.
2018-02-23Remove --quiet argument when installing localesMike FABIAN
Using this argument hides problems. I would like to see when something fails. * localedata/Makefile: Remove --quiet argument when installing locales
2018-02-23Use / instead of - in d_fmt for pt_BR and pt_PT [BZ #17438]Mike FABIAN
[BZ #17438] * localedata/locales/pt_BR (LC_TIME): use / instead of - in d_fmt. * localedata/locales/pt_PT (LC_TIME): likewise
2018-02-23Use “copy "es_BO"” in LC_TIME of es_CU, es_CL, and es_ECMike FABIAN
LC_TIME in these 4 locales is identical, using “copy "es_BO"” makes that more obvious. [BZ #22646] * localedata/locales/es_CL (LC_TIME): copy "es_BO". * localedata/locales/es_CU (LC_TIME): copy "es_BO". * localedata/locales/es_EC (LC_TIME): copy "es_BO".

2018-02-22Refactor atfork handlersAdhemerval Zanella
Current implementation (sysdeps/nptl/fork.c) replicates the atfork handlers list backward to invoke the child handlers after fork/clone syscall. The internal atfork handlers is implemented as a single-linked list so a lock-free algorithm can be used, trading fork mulithread call performance for some code complexity and dynamic stack allocation (since the backwards list should not fail). This patch refactor it to use a dynarary instead of a linked list. It simplifies the external variables need to be exported and also the internal atfork handler member definition. The downside is a serialization of fork call in multithread, since to operate on the dynarray the internal lock should be used. However as noted by Florian, it already acquires external locks for malloc and libio so it is already hitting some lock contention. Besides, posix_spawn should be faster and more scalable to run external programs in multithread environments. Checked on x86_64-linux-gnu. * nptl/Makefile (routines): Remove unregister-atfork. * nptl/register-atfork.c (fork_handler_pool): Remove variable. (fork_handler_alloc): Remove function. (fork_handlers, fork_handler_init): New variables. (__fork_lock): Rename to atfork_lock. (__register_atfork, __unregister_atfork, libc_freeres_fn): Rewrite to use a dynamic array to add/remove atfork handlers. * sysdeps/nptl/fork.c (__libc_fork): Likewise. * sysdeps/nptl/fork.h (__fork_lock, __fork_handlers, __linkin_atfork): Remove declaration. (fork_handler): Remove next, refcntr, and need_signal member. (__run_fork_handler_type): New enum. (__run_fork_handlers): New prototype. * sysdeps/nptl/libc-lockP.h (__libc_atfork): Remove declaration.
2018-02-22Rename nptl-signals.h to internal-signals.hAdhemerval Zanella
This patch renames the nptl-signals.h header to internal-signals.h. On Linux the definitions and functions are not only NPTL related, but used for other POSIX definitions as well (for instance SIGTIMER for posix times, SIGSETXID for id functions, and signal block/restore helpers) and since generic functions will be places and used in generic implementation it makes more sense to decouple it from NPTL. Checked on x86_64-linux-gnu. * sysdeps/nptl/nptl-signals.h: Move to ... * sysdeps/generic/internal-signals.h: ... here. Adjust internal comments. * sysdeps/unix/sysv/linux/internal-signals.h: Add include guards. (__nptl_is_internal_signal): Rename to __is_internal_signal. (__nptl_clear_internal_signals): Rename to __clear_internal_signals. * sysdeps/unix/sysv/linux/raise.c: Adjust nptl-signal.h to include-signals.h rename. * nptl/pthreadP.h: Likewise. * sysdeps/unix/sysv/linux/spawni.c (__spawni_child): Call __is_internal_signal instead of __nptl_is_internal_signal.
2018-02-22RISC-V: fmax/fmin: Handle signalling NaNs correctly.Andrew Waterman
RISC-V's fmax(sNAN,4) returns 4 but glibc expects it to return qNAN. * sysdeps/riscv/rvd/s_fmax.c (__fmax): Handle sNaNs correctly. * sysdeps/riscv/rvd/s_fmin.c (__fmin): Likewise. * sysdeps/riscv/rvf/s_fmaxf.c (__fmaxf): Likewise. * sysdeps/riscv/rvf/s_fminf.c (__fminf): Likewise.
