* Remove __qaddr_t.Joseph Myers2017-08-091-1/+0
| | | | | | | | | | | | bits/types.h defines a type __qaddr_t that is not used anywhere in glibc. It doesn't appear to be widely used outside glibc either (judging by codesearch.debian.net, where hits are generally copies of definitions of this type, not uses), so it seems appropriate to remove this type, which this patch does. Tested for x86_64. * posix/bits/types.h (__qaddr_t): Remove.
* Do not use __ptr_t.Joseph Myers2017-08-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

* Use __builtin_popcount in __sched_cpucount [BZ #21696]H.J. Lu2017-07-011-17/+10
| | | | | | | | | | | | posix/sched_cpucount.c assumes that size of __cpu_mask == size of long, which is incorrect for x32. This patch uses __builtin_popcount, which is availabe in GCC 4.9, in posix/sched_cpucount.c. Tested on i686, x86-64 and x32 with multi-arch disabled.

* Fix wait3 namespace (bug 21625).Joseph Myers2017-06-191-1/+2
| | | | | | | | | | | | | | The wait3 function was removed in the 2001 edition of POSIX. sys/wait.h wrongly declares it for the 2001 and 2008 editions of POSIX when XSI features are enabled. This patch fixes the conditionals. Tested for x86_64. [BZ #21625] * posix/sys/wait.h (strust rusage forward declaration): Change [__USE_XOPEN_EXTENDED] conditional to [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K]. (wait3): Likewise.
* Define struct rusage in sys/wait.h when required (bug 21575).Joseph Myers2017-06-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require sys/wait.h to include the definition of struct rusage. This is missing in glibc. This patch adds the required definition. struct rusage is moved to a new header bits/types/struct_rusage.h to avoid bringing in the whole of sys/resource.h (although the standards in question do allow the whole of sys/resource.h to be brought in). In the five bits/resource.h headers, the only variation between the definitions of struct rusage is that the sysdeps/unix/sysv/linux version is prepared for x32 (by having anonymous unions with __syscall_slong_t fields) and the others are not. Thus, this version is suitable for use generically (everything other than x32 simply has __syscall_slong_t the same as long int, so there are no API or ABI changes involved, and anonymous unions are already a required language feature for glibc headers elsewhere), and this patch uses it as a base for the single implementation of bits/types/struct_rusage.h. Tested for x86_64, and with build-many-glibcs.py. [BZ #21575] * resource/bits/types/struct_rusage.h: New file. * include/bits/types/struct_rusage.h: Likewise. * bits/resource.h (struct rusage): Include <bits/types/struct_rusage.h> instead of defining here. * sysdeps/unix/sysv/linux/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/alpha/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/mips/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/resource.h (struct rusage): Likewise. * resource/Makefile (headers): Add bits/types/struct_rusage.h. * posix/sys/wait.h [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8]: Include <bits/types/struct_rusage.h>

* Remove __need_schedparam and __cpu_set_t_defined.Zack Weinberg2017-06-123-5/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bits/sched.h has logic to expose only an impl-namespace variant of struct sched_param (i.e. struct __sched_param), but nothing uses it, and the only header that includes bits/sched.h is sched.h. The __need_schedparam logic can therefore be removed. bits/sched.h also has a great deal of code relating to cpu_set_t objects that was *almost* the same between the two versions of bits/sched.h in the tree; a little spelunking indicated that this is because some bug fixes got applied to the Linux-specific bits/sched.h but not the generic one. Introduce a new header, bits/cpu-set.h, containing the version of that code with the bugfixes, have sched.h include it directly, and delete all of the code from both versions of bits/sched.h. Also remove the unnecessary name mangling in the definition of struct sched_param -- POSIX specifies a field 'sched_priority', so there is no reason to define it as '__sched_priority' and then paper over that with a macro. (Just in case someone was using the internal name, 'sched_priority' remains a macro defined to expand to itself, and '__sched_priority' now expands to 'sched_priority'.) Finally, as long as I'm touching these files anyway, merge new constants from linux/sched.h into the Linux bits/sched.h. * bits/sched.h: Remove __need_schedparam logic and replace with a normal multiple-include guard. Change field name in struct sched_param from __sched_priority to sched_priority. Delete everything under #ifndef __cpu_set_t_defined. * sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants. * posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h. For compatibility, #define sched_priority to itself, and #define __sched_priority as sched_priority. * posix/bits/cpu-set.h: New file containing, verbatim, the code that was under #ifndef __cpu_set_t_defined in sysdeps/unix/sysv/linux/bits/sched.h. * include/bits/cpu-set.h: New wrapper. * posix/Makefile: Install bits/cpu-set.h.
* Fix waitid namespace (bug 21561).Joseph Myers2017-06-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In sys/wait.h, waitid and associated constants and types are UX-shaded in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so should be appropriately conditional in the headers. This patch fixes the conditionals accordingly. (WCONTINUED is actually still XSI-shaded in POSIX.1:2008, but W* is also reserved there without XSI-shading, so nothing special needs to be done about the conditionals on WCONTINUED to conform to POSIX.1:2008 namespace rules.) Tested for x86_64. [BZ #21561] * posix/sys/wait.h (idtype_t): Change [__USE_XOPEN] condition to [__USE_XOPEN_EXTENDED]. (id_t): Likewise. (include of <bits/types/siginfo_t.h): Likewise. (waitid): Likewise. * sysdeps/unix/sysv/linux/bits/waitflags.h (WSTOPPED): Condition on [__USE_XOPEN_EXTENDED || __USE_XOPEN2K8]. (WEXITED): Likewise. (WCONTINUED): Likewise. (WNOWAIT): Likewise. * conform/Makefile (test-xfail-XPG4/stdlib.h/conform): Remove. (test-xfail-XPG4/sys/wait.h/conform): Likewise. (test-xfail-POSIX/sys/wait.h/conform): Likewise.
* Condition signal.h inclusion in sys/wait.h (bug 21560).Joseph Myers2017-06-091-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | sys/wait.h includes signal.h unconditionally. But the permission to do so is UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so this should not be unconditional. This patch fixes this conservatively: the include is kept, but conditioned on the standards that permit it (meaning it is still present by default, because non-XSI POSIX.1:2008 is enabled by default). <bits/types.h> is now included unconditionally to provide the required definition of __pid_t; it was previously included via <signal.h>. Some standards require pid_t to be defined here, and all allow it to be defined here; previously defined via <signal.h>, it's now defined directly in this header. Tested for x86_64. This does not fix any of the sys/wait.h conformtest failures, but substantially reduces the number of namespace failures for sys/wait.h for XPG4 and POSIX. [BZ #21560] * posix/sys/wait.h: Condition include of <signal.h> on [__USE_XOPEN_EXTENDED || __USE_XOPEN2K8]. Include <bits/types.h> unconditionally. [!__pid_t_defined] (pid_t): Define typedef.
* Remove __need macros from signal.h.Zack Weinberg2017-05-203-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t, sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a scalar, so it's now directly available from bits/types.h. The others get bits/types/ headers. Side effects include: There have been small changes to which non-signal headers expose which subset of the signal-related types. A couple of architectures' nested siginfo_t fields had to be renamed to prevent undesired macro expansion. Internal code that wants to manipulate signal masks must now include <sigsetops.h> (which is not installed) and should be aware that __sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no longer return a value (unlike the public API). Relatedly, the public signal.h no longer declares any of those functions. The obsolete sigmask() macro no longer has a system-specific definition -- in the cases where it matters, it didn't work anyway. New Linux architectures should create bits/siginfo-arch.h and/or bits/siginfo-consts-arch.h to customize their siginfo_t, rather than duplicating everything in bits/siginfo.h (which no longer exists). Add new __SI_* macros if necessary.

* posix: Consolidate Linux pause syscallAdhemerval Zanella2017-05-181-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates the pause Linux implementation on sysdeps/unix/sysv/linux/pause.c. If defined the pause syscall (__NR_pause) will be used, other ppoll with 0 arguments will be used instead. It has the small advantage of generic pause implementation with uses rt_sigprocmask plus rt_sigsuspend because it requires only one syscall and the pause is done atomically regarding signal handling (for instance, pause may not be interrupted if the signal arrives between the rt_sigprocmask and rt_sigsuspend syscall). Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu. * sysdeps/unix/sysv/linux/generic/pause.c: Remove file. * sysdeps/unix/sysv/linux/sparc/sparc64/pause.c: Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h [__arch64__] (__NR_pause): Undefine. * sysdeps/unix/sysv/linux/pause.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove pause from auto-generation list.

IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus (which means several ad-hoc tests for __cplusplus can go away). libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is defined; in particular, _ISOMAC mode does not get config.h automatically anymore. There are still quite a few tests that need to see internal gunk of one variety or another. For them, we now have 'tests-internal' and 'test-internal-extras'; files in this category will still be compiled with MODULE_NAME=nonlib, and everything proceeds as it always has. The bulk of this patch is moving tests from 'tests' to 'tests-internal'. There is also 'tests-static-internal', which has the same effect on files in 'tests-static', and 'modules-names-tests', which has the *inverse* effect on files in 'modules-names' (it's inverted because most of the things in modules-names are *not* tests). For both of these, the file must appear in *both* the new variable and the old one. There is also now a special case for when libc-symbols.h is included without MODULE_NAME being defined at all. (This happens during the creation of libc-modules.h, and also when preprocessing Versions files.) When this happens, IS_IN is set to be always false and _ISOMAC is *not* defined, which was the status quo, but now it's explicit. The remaining changes to C source files in this patch seemed likely to cause problems in the absence of the main change. They should be relatively self-explanatory. In a few cases I duplicated a definition from an internal header rather than move the test to tests-internal; this was a judgement call each time and I'm happy to change those however reviewers feel is more appropriate. * Makerules: New subdir configuration variables 'tests-internal' and 'test-internal-extras'. Test files in these categories will still be compiled with MODULE_NAME=nonlib. Test files in the existing categories (tests, xtests, test-srcs, test-extras) are now compiled with MODULE_NAME=testsuite. New subdir configuration variable 'modules-names-tests'. Files which are in both 'modules-names' and 'modules-names-tests' will be compiled with MODULE_NAME=testsuite instead of MODULE_NAME=extramodules. (gen-as-const-headers): Move to tests-internal. (do-tests-clean, common-mostlyclean): Support tests-internal. * Makeconfig (built-modules): Add testsuite. * Makefile: Change libof-check-installed-headers-c and libof-check-installed-headers-cxx to 'testsuite'. * Rules: Likewise. Support tests-internal. * benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove extra-modules.mk. * config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here. * include/libc-symbols.h: Move definitions of _GNU_SOURCE, PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the very top of the file and rationalize their order. If MODULE_NAME is not defined at all, define IS_IN to always be false, and don't define _ISOMAC. If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are true, define _ISOMAC and suppress everything else in this file, starting with the inclusion of config.h. Do check for inappropriate definitions of __OPTIMIZE__ and __FAST_MATH__ here, but only if _ISOMAC is not defined. Correct some out-of-date commentary. * include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE and _Mlong_double_ before including math.h. * include/string.h: If _ISOMAC is defined, don't expose _STRING_ARCH_unaligned.

* Move shared pthread definitions to common headersAdhemerval Zanella2017-05-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes all the replicated pthread definition accross the architectures and consolidates it on shared headers. The new organization is as follow: * Architecture specific definition (such as pthread types sizes) are place in the new pthreadtypes-arch.h header in arch specific path. * All shared structure definition are moved to a common NPTL header at sysdeps/nptl/bits/pthreadtypes.h (with now includes the arch specific one for internal definitions). * Also, for C11 future thread support, both mutex and condition definition are placed in a common header at sysdeps/nptl/bits/thread-shared-types.h.

* Fix network headers stdint.h namespace (bug 21455).Joseph Myers2017-05-041-24/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail for UNIX98 and XPG42 because of inclusion of stdint.h, which defines macros not permitted in those headers for those standards. UNIX98 allows them to include inttypes.h, but (predating C99) has restricted inttypes.h contents (not yet tested in the conform/ tests) not including those macros; XPG4.2 has no such permission and no inttypes.h / stdint.h at all. This patch rearranges the headers to avoid this issue. intN_t definitions move to bits/stdint-intn.h, and uintN_t definitions to bits/stdint-uintn.h. (These are not bits/types/ headers because they each define four types. They are separate rather than just a single header because sys/types.h defines intN_t but u_intN_t rather than uintN_t - and while sys/types.h could define uintN_t because of the POSIX reservation of *_t, existing practice there is largely to condition types on appropriate feature test macros, and indeed there is at least one open bug report (14553) about a type that's not so-conditioned, so maybe types there should actually have conditions added where appropriate.) The affected network headers are then made to include bits/stdint-uintn.h instead of stdint.h. This allows six XFAILs to be removed. This doesn't do anything about inttypes.h defining more than it should for UNIX98, but we don't have conformtest expectations for that case at present (and my inclination is that a fix for that should be as local as possible - affecting only inttypes.h, not stdint.h, only for the case of __USE_UNIX98 && !__USE_ISOC99).

* Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).Joseph Myers2017-04-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/socket.h includes sys/uio.h to get the definition of the iovec structure. POSIX allows sys/socket.h to make all sys/uio.h symbols visible. However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this results in conformtest failures (for sys/socket.h and other headers that include it): Namespace violation: "UIO_MAXIOV" Namespace violation: "readv" Namespace violation: "writev" Now, there is some ambiguity in POSIX about what namespace reservations apply in this case - see http://austingroupbugs.net/view.php?id=1127 - but glibc convention would still avoid declaring readv and writev, for example, for feature test macros that don't include them (if only headers from the relevant standard are included), even if such declarations are permitted, so there is a bug here according to glibc conventions. This patch moves the struct iovec definition to a new bits/types/struct_iovec.h header and includes that from sys/socket.h instead of including the whole of sys/uio.h. This fixes the namespace issue; however, three files in glibc that were relying on the implicit inclusion needed to be updated to include sys/uio.h explicitly. So there is a question of whether sys/socket.h should continue to include sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or __USE_XOPEN || __USE_MISC, for greater compatibility with code that (wrongly) expects this optional inclusion to be present there. (I think the three affected files in glibc should still have explicit sys/uio.h inclusions added in any case, however.) Tested for x86_64.

* Consolidate Linux mmap implementation (BZ#21270)Adhemerval Zanella2017-04-121-19/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates all Linux mmap implementations on default sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required architecture specific requeriments a new internal header is created (mmap_internal.h) where each architecture add its specific code requirements. Currently only x86_64 (to define MMAP_PREPARE to add MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k (which have variable minimum page sizes), and MIPS n32 (which zero extend the offset to handle negative one correctly) redefine the new header. The patch also fixes BZ#21270 where default mmap64 on architectures which uses mmap2 silent truncates large offsets value (larger than 1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with 4096 bytes page size). The new consolidate implementation returns EINVAL as allowed by POSIX. It also adds a tests for on current tst-mmap-offset one. I have run a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc, powerpc64le, sparc64, and sparcv9 without any regressions.

Because this code is shared with gnulib, it winds up being cleanest to split getopt.h into *four* headers. getopt_core.h and getopt_ext.h will be shared with gnulib, getopt_posix.h will be just for glibc, and each project will have its own copy of getopt.h. * posix/bits/getopt_core.h, posix/bits/getopt_ext.h: New files, intended to be shared with gnulib. * posix/bits/getopt_posix.h: New file, not intended to be shared with gnulib. * posix/getopt.h: Now just includes features.h, bits/getopt_core.h, and bits/getopt_ext.h. Will no longer be shared with gnulib. * include/bits/getopt_core.h, include/bits/getopt_ext.h * include/bits/getopt_posix.h: New wrappers. * posix/Makefile: Install new headers. * posix/unistd.h, libio/stdio.h: Include bits/getopt_posix.h instead of getopt.h.
* getopt: merge _GL_UNUSED annotations from gnulibZack Weinberg2017-04-071-1/+2
| | | | | | | | | | | | | | | | gnulib now has annotations on at least some functions to cater to compilation with -Wunused-parameter. In order to follow suit cleanly, I've added to libc-symbols.h some of the _GL_* macros that gnulib-common.m4 puts into config.h. (I don't think they belong in sys/cdefs.h, at least not without further thought.) At this point all gnulib-side changes to getopt.c have been merged. * include/libc-symbols.h: For gnulib compatibility, define _GL_UNUSED, _GL_UNUSED_LABEL, _GL_ATTRIBUTE_PURE, and _GL_ATTRIBUTE_CONST. * posix/getopt.c (_getopt_initialize): Mark argc and argv parameters with _GL_UNUSED.
* getopt: merge from gnulib: alloca avoidanceZack Weinberg2017-04-072-127/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In one place, glibc's getopt uses alloca to construct a linked list of possibilities for an "ambiguous" long option. In gnulib, malloc should be used instead. Providing for both cases complicates things a fair bit. Instead of merging straight across, therefore, I have chosen to rewrite it using a boolean vector instead of a linked list. There is then only one allocation that might need freeing; in glibc it can honor __libc_use_alloca as usual, and in gnulib we define __libc_use_alloca to always be false, so we don't need ifdefs in the middle of the function. This should also be slightly more efficient in the normal case of long options being fully spelled out -- I think most people aren't even aware they _can_ sometimes abbreviate long options. One interesting consequence is that the list of possibilities is now printed in exactly the order they appear in the list of long options, instead of the first possibility being shuffled to the end. This shouldn't be a big deal but it did break one test that relied on the exact text of this error message. (The reason the previous patch was "in aid of" merging from gnulib is I didn't want to have to make this change in two places.) (The patch looks bigger than it really is because there's a fair bit of reindentation and code rearrangement.) * posix/getopt.c: When used standalone, define __libc_use_alloca as always false and alloca to abort if called. (process_long_option): Rewrite handling of ambiguous long options to use a single boolean vector, not a linked list; use __libc_use_alloca to decide whether to allocate this using alloca. * posix/tst-getopt_long1.c: Adjust text of expected error message.
* getopt: refactor long-option handlingZack Weinberg2017-04-072-305/+212
| | | | | | | | | | | | | | | There were two copies of the bulk of the code to handle long options. Now there is only one. (Yes, this is in aid of merging from gnulib.) The change to bug-getopt4.c clarifies the error messages when the test fails. * posix/getopt.c (process_long_option): New function split out from _getopt_internal_r. (_getopt_internal_r): Replace both copies of the long-option processing code with calls to process_long_option. * posix/bug-getopt4.c (one_test): Print argv[0] in error messages. (do_test): Differentiate argv[0] in the two subtests.
* getopt: tidy up _getopt_initialize a bitZack Weinberg2017-04-072-16/+6
| | | | | | | | | | | | | | | | _getopt_data.__posixly_correct is completely redundant to _getopt_data.__ordering, and some work that logically belongs in _getopt_initialize was being done by _getopt_internal_r, making the code harder to understand. As a side effect, getenv will no longer be called if the first character of the options string is '+' or '-', which is probably a Good Thing. (Perhaps we should have a flag character that specifically asks for the permutation behavior?) * posix/getopt_int.h (_getopt_data): Remove __posixly_correct field. * posix/getopt.c (_getopt_internal_r): Move some initialization code... (_getopt_initialize): ...here. Don't set d->__posixly_correct.
* getopt: merge from gnulib: function prototype adjustmentsZack Weinberg2017-04-074-65/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For standards compliance, getopt, getopt_long, and getopt_long_only in glibc have to take 'char *const *argv' even though they can mutate the array. gnulib has tried to clean this up as much as possible: all the internal functions use 'char **argv', and when used standalone, so do getopt_long and getopt_long_only. Also brought over are __nonnull annotations, corrections to documentation, and apparently it is no longer necessary to worry about conflicting prototypes for getopt. The macroification of the definitions of getopt and __posix_getopt goes beyond what is currently in gnulib. At this point getopt1.c and getopt_int.h are identical to their gnulib versions. * posix/getopt.h: Add backup definition of __nonnull for consistency with gnulib. Define __getopt_argv_const to const if not already defined. (getopt): Update doc comment from gnulib. Prototype unconditionally. Add __nonnull annotation. (__posix_getopt): Add __nonnull annotation. (getopt_long, getopt_long_only): Use __getopt_argv_const in prototypes for consistency with gnulib. Add __nonnull annotations. * posix/getopt.c (_getopt_initialize, _getopt_internal_r) (getopt_internal): Change 'argv' argument to type 'char **'. Remove now-unnecessary casts. (getopt, __posix_getopt): Eliminate repetition with a macro. Cast 'argv' to 'char **' when calling _getopt_internal. * posix/getopt1.c (getopt_long, getopt_long_only): Use __getopt_argv_const for consistency with gnulib. Cast 'argv' to 'char **' when calling _getopt_internal. (_getopt_long_r, _getopt_long_only_r): Change 'argv' argument to type 'char **'. (main): Constify 'long_options'. * posix/getopt_int.h (getopt_internal, _getopt_internal_r) (_getopt_long_r, _getopt_long_only_r): Change 'argv' argument to type 'char **'.
* getopt: clean up error reportingZack Weinberg2017-04-073-309/+342
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getopt can print a whole bunch of error messages, and when used standalone (from gnulib) it uses fprintf to do that. But fprintf is a cancellation point and getopt isn't, and also applying fprintf to a stream in wide-character mode is not allowed. glibc has an internal function called __fxprintf that writes a narrow format string to a stream regardless of mode, but it only handles ASCII format strings, and it's still a cancellation point. getopt's messages are translated, so they might not be ASCII. So getopt has an error message to an asprintf buffer, monkeys with internal flag bits on stderr to disable cancellation, and then calls __fxprintf(stderr, "%s", buffer). There isn't even a helper function, the code is duplicated every time. This patch fixes __fxprintf to handle arbitrary multibyte format strings, and adds a variant __fxprintf_nocancel that does the same thing but also isn't a cancellation point. (It still _works_ by monkeying with internal flag bits on the FILE, but that's not really a layering violation for code in stdio-common.) All of the #ifdef _LIBC blocks can then be reduced to their standalone versions with a little help from some macros at the top of the file. I also wrote a test case to verify that getopt really isn't a cancellation point, and I'm glad I did, because it found two bugs, one of which wasn't even to do with cancellation (see previous patch). * stdio-common/fxprintf.c (__fxprintf_nocancel): New function. (locked_vfxprintf): New helper function. Handle arbitrary multibyte strings, not just ASCII. * include/stdio.h: Declare __fxprintf_nocancel. * posix/getopt.c: When _LIBC is defined, define fprintf to __fxprintf_nocancel, flockfile to _IO_flockfile, and funlockfile to _IO_funlockfile. When neither _LIBC nor _POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and funlockfile as no-ops. (_getopt_internal_r): Remove all internal #ifdef _LIBC blocks; the standalone error-printing code can now be used for libc as well. Add an flockfile/funlockfile pair around one case where the error message is printed in several chunks. Don't use fputc. * posix/tst-getopt-cancel.c: New test. * posix/Makefile: Run it.
* getopt: fix fencepost error in ambiguous-W-option handlingZack Weinberg2017-04-071-1/+0
| | | | | | | | | | | | | | | | | getopt_long contains an undocumented (AFAICT) feature in which, if you put "W;" in the short-options list, then '-W foo' and '-Wfoo' are treated as equivalent to '--foo'. This is implemented with a partial second copy of the code for handling long options, and that code increments optind one too many times when recovering from an ambiguous abbreviated option, which can cause the main loop to walk past the end of argv and crash. I discovered this while writing a test case that tries to exercise all of getopt's error reporting paths; I wouldn't be surprised to learn that this feature is never used by real applications. * posix/getopt.c (_getopt_internal_r): Don't increment d->optind a second time when reporting ambiguous -W options.
* getopt: merge straightforward changes from gnulibZack Weinberg2017-04-073-158/+80
| | | | | | | | | | | | | | | | | This covers changes with little or no consequences when the code is used in glibc. * posix/getopt_int.h: Include getopt.h. Use impl-namespace names for all arguments to _getopt_internal and _getopt_internal_r. Declare __ordering enum outside the struct. Harmonize comments with gnulib. * posix/getopt1.c: Simplify #ifdeffage at top of file. Remove ELIDE_CODE logic entirely. Move inclusion of stdlib.h to #ifdef TEST block and make unconditional. Do not define NULL. * posix/getopt.c: Partial merge from gnulib, covering the initial includes and global declarations, commentary, and a couple of semantically-neutral code changes.
* getopt: merge from gnulib: don't use `...' quotesZack Weinberg2017-04-074-66/+66
| | | | | | | | | | | | I'm not sure whether this is official GNU style now, but `...' quotes haven't looked properly balanced in most people's terminal fonts since 2001ish? and gnulib has chosen to switch over to '...' quotes. I'm merging this separately from the other changes in gnulib because it's very mechanical. * posix/getopt.c, posix/getopt.h, posix/getopt1.c, posix/getopt_int.h: Use '...' instead of `...' for quotation marks inside comments and strings.
* getopt: remove USE_NONOPTION_FLAGSZack Weinberg2017-04-074-175/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc's implementation of getopt includes code to parse an environment variable named _XXX_GNU_nonoption_argv_flags_ (where XXX is the current process's PID in decimal); but all of it has been #ifdefed out since 2001, with no official way to turn it back on. According to commentary in our config.h.in, bash version 2.0 set this environment variable to indicate argv elements that were the result of glob expansion and therefore should not be treated as options, but the feature was "disabled later" because "it caused problems". According to bash's CHANGES file, "later" was release 2.01; it gives no more detail about what the problems were. Version 2.0 of bash was released on the last day of 1996, and version 2.01 in June of 1997. Twenty years later, I think it is safe to assume that this environment variable isn't coming back. * config.h.in (USE_NONOPTION_FLAGS): Remove. * csu/init-first.c: Remove all #ifdef USE_NONOPTION_FLAGS blocks. * sysdeps/mach/hurd/i386/init-first.c: Likewise. * posix/getopt_int.h: Likewise. * posix/getopt.c: Likewise. Also remove SWAP_FLAGS and the __libc_argc and __libc_argv externs, which were only used by #ifdef USE_NONOPTION_FLAGS blocks. * posix/getopt_init.c: Remove file. * posix/Makefile (routines): Remove getopt_init. * include/getopt.h: Don't declare __getopt_initialize_environment. * manual/getopt.texi: Remove mention of USE_NONOPTION_FLAGS in a comment.
* Fix test-errno issuesAdhemerval Zanella2017-03-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes multiple issues of test-errno.c (9a56f8718341): - Rename Linux test-errno.c to test-errno-linux.c to avoid build the same source for both tests. - Add a mlock check for 32 bits build running on 64 bits kernels. Althuough man pages states that mlock fails with EINVAL if final address overflows, kernels does not return it for aforementioned condition (it returns ENOMEM instead). Although it seems to be a kernel issue for compat syscall handling, I think it is worth to still check syscall return and document the behavior. - Initialize option lenght for setsockopt check. - Change open test from EINVAL to EISDIR. Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits kernel). * posix/test-errno.c (do_test): Initialize setsockopt optlen. * sysdeps/unix/sysv/linux/test-errno.c: Move to ... * sysdeps/unix/sysv/linux/test-errno-linux.c: ... here. (test_wrp_rv): Fix format. (test_wrp_rv2): New macro. (do_test): Handle mlock return on 64 bits kernels with 32 bits binaries.

* Narrowing the visibility of libc-internal.h even further.Zack Weinberg2017-03-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar to what was done with libc-diag.h, I have split the definitions of cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN to a new header, libc-pointer-arith.h. It then occurred to me that the remaining declarations in libc-internal.h are mostly to do with early initialization, and probably most of the files including it, even in the core code, don't need it anymore. Indeed, only 19 files actually need what remains of libc-internal.h. 23 others need libc-diag.h instead, and 12 need libc-pointer-arith.h instead. No file needs more than one of them, and 16 don't need any of them! So, with this patch, libc-internal.h stops including libc-diag.h as well as losing the pointer arithmetic macros, and all including files are adjusted. * include/libc-pointer-arith.h: New file. Define cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN here. * include/libc-internal.h: Definitions of above macros moved from here.
