2024-04-02Always define __USE_TIME_BITS64 when 64 bit time_t is usedAdhemerval Zanella1-2/+2
It was raised on libc-help [1] that some Linux kernel interfaces expect the libc to define __USE_TIME_BITS64 to indicate the time_t size for the kABI. Different than defined by the initial y2038 design document [2], the __USE_TIME_BITS64 is only defined for ABIs that support more than one time_t size (by defining the _TIME_BITS for each module). The 64 bit time_t redirects are now enabled using a different internal define (__USE_TIME64_REDIRECTS). There is no expected change in semantic or code generation. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, and arm-linux-gnueabi [1] https://sourceware.org/pipermail/libc-help/2024-January/006557.html [2] https://sourceware.org/glibc/wiki/Y2038ProofnessDesign Reviewed-by: DJ Delorie <dj@redhat.com>

2021-06-15y2038: Add support for 64-bit time on legacy ABIsAdhemerval Zanella1-0/+20
A new build flag, _TIME_BITS, enables the usage of the newer 64-bit time symbols for legacy ABI (where 32-bit time_t is default). The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time.

2019-03-13Use a proper C tokenizer to implement the obsolete typedefs test.Zack Weinberg1-25/+8
The test for obsolete typedefs in installed headers was implemented using grep, and could therefore get false positives on e.g. “ulong” in a comment. It was also scanning all of the headers included by our headers, and therefore testing headers we don’t control, e.g. Linux kernel headers. This patch splits the obsolete-typedef test from scripts/check-installed-headers.sh to a separate program, scripts/check-obsolete-constructs.py. Being implemented in Python, it is feasible to make it tokenize C accurately enough to avoid false positives on the contents of comments and strings. It also only examines $(headers) in each subdirectory--all the headers we install, but not any external dependencies of those headers. Headers whose installed name starts with finclude/ are ignored, on the assumption that they contain Fortran. It is also feasible to make the new test understand the difference between _defining_ the obsolete typedefs and _using_ the obsolete typedefs, which means posix/{bits,sys}/types.h no longer need to be exempted. This uncovered an actual bug in bits/types.h: __quad_t and __u_quad_t were being used to define __S64_TYPE, __U64_TYPE, __SQUAD_TYPE and __UQUAD_TYPE. These are changed to __int64_t and __uint64_t respectively. This is a safe change, despite the comments in bits/types.h claiming a difference between __quad_t and __int64_t, because those comments are incorrect. In all current ABIs, both __quad_t and __int64_t are ‘long’ when ‘long’ is a 64-bit type, and ‘long long’ when ‘long’ is a 32-bit type, and similarly for __u_quad_t and __uint64_t. (Changing the types to be what the comments say they are would be an ABI break, as it affects C++ name mangling.) This patch includes a minimal change to make the comments not completely wrong. sys/types.h was defining the legacy BSD u_intN_t typedefs using a construct that was not necessarily consistent with how the C99 uintN_t typedefs are defined, and is also too complicated for the new script to understand (it lexes C relatively accurately, but it does not attempt to expand preprocessor macros, nor does it do any actual parsing). This patch cuts all of that out and uses bits/types.h's __uintN_t typedefs to define u_intN_t instead. This is verified to not change the ABI on any supported architecture, via the c++-types test, which means u_intN_t and uintN_t were, in fact, consistent on all supported architectures.

2018-02-06Only define loff_t for __USE_MISC (bug 14553).Joseph Myers1-2/+1
Bug 14553 reports that sys/types.h defines loff_t unconditionally, despite it not being part of any supported standard. This is permitted by the POSIX *_t reservation, but as a quality-of-implementation issue it's still best not to define it except for __USE_MISC. This patch conditions the definition accordingly, updating a macro in sysdeps/unix/sysv/linux/sys/quota.h to use __loff_t so it still works even if __USE_MISC is not defined. codesearch.debian.net suggests there are quite a lot of loff_t uses outside glibc, but it might well make sense to change all (few) uses of loff_t or __loff_t inside glibc to use off64_t or __off64_t instead, leaving only the definitions, treating this name as obsolescent. Tested for x86_64. [BZ #14553] * posix/sys/types.h (loff_t): Only define for [__USE_MISC]. * sysdeps/unix/sysv/linux/sys/quota.h (dqoff): Use __loff_t instead of loff_t.

2017-06-19Fix wait3 namespace (bug 21625).Joseph Myers1-1/+2

2017-06-19Define struct rusage in sys/wait.h when required (bug 21575).Joseph Myers1-0/+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.

2017-06-09Fix waitid namespace (bug 21561).Joseph Myers1-2/+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.)

2017-06-09Condition signal.h inclusion in sys/wait.h (bug 21560).Joseph Myers1-2/+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.
2017-05-20Remove __need macros from signal.h.Zack Weinberg1-2/+1
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.

2017-05-04Fix network headers stdint.h namespace (bug 21455).Joseph Myers1-24/+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).

2016-09-23Installed-header hygiene (BZ#20366): time.h types.Zack Weinberg2-8/+5
Many headers are expected to expose a subset of the type definitions in time.h. time.h has a whole bunch of messy logic for conditionally defining some its types and structs, but, as best I can tell, this has never worked 100%. In particular, __need_timespec is ineffective if _TIME_H has already been defined, which means that if you compile #include <time.h> #include <sched.h> with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get In file included from test.c:2:0: /usr/include/sched.h:74:57: warning: "struct timespec" declared inside parameter list will not be visible outside of this definition or declaration extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW; ^~~~~~~~ And if you want to _use_ sched_rr_get_interval in a TU compiled that way, you're hosed. This patch replaces all of that with small bits/types/TYPE.h headers as introduced earlier. time.h and bits/time.h are now *much* simpler, and a lot of other headers are slightly simpler. * time/time.h, bits/time.h, sysdeps/unix/sysv/linux/bits/time.h: Remove all logic conditional on __need macros. Move all the conditionally defined types to their own headers... * time/bits/types/clock_t.h: Define clock_t here. * time/bits/types/clockid_t.h: Define clockid_t here. * time/bits/types/struct_itimerspec.h: Define struct itimerspec here. * time/bits/types/struct_timespec.h: Define struct timespec here. * time/bits/types/struct_timeval.h: Define struct timeval here. * time/bits/types/struct_tm.h: Define struct tm here. * time/bits/types/time_t.h: Define time_t here. * time/bits/types/timer_t.h: Define timer_t here. * time/Makefile: Install the new headers. * bits/resource.h, io/fcntl.h, io/sys/poll.h, io/sys/stat.h * io/utime.h, misc/sys/select.h, posix/sched.h, posix/sys/times.h * posix/sys/types.h, resolv/netdb.h, rt/aio.h, rt/mqueue.h * signal/signal.h, pthread/semaphore.h, sysdeps/nptl/pthread.h * sysdeps/unix/sysv/linux/alpha/bits/resource.h * sysdeps/unix/sysv/linux/alpha/sys/acct.h * sysdeps/unix/sysv/linux/bits/resource.h * sysdeps/unix/sysv/linux/bits/timex.h * sysdeps/unix/sysv/linux/mips/bits/resource.h * sysdeps/unix/sysv/linux/net/ppp_defs.h * sysdeps/unix/sysv/linux/sparc/bits/resource.h * sysdeps/unix/sysv/linux/sys/acct.h * sysdeps/unix/sysv/linux/sys/timerfd.h * sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h * time/sys/time.h, time/sys/timeb.h Use the new bits/types headers. * include/time.h: Remove __need logic. * include/bits/time.h * include/bits/types/clock_t.h, include/bits/types/clockid_t.h * include/bits/types/time_t.h, include/bits/types/timer_t.h * include/bits/types/struct_itimerspec.h * include/bits/types/struct_timespec.h * include/bits/types/struct_timeval.h * include/bits/types/struct_tm.h: New wrapper headers.
2016-08-03Deprecate inclusion of <sys/sysmacros.h> by <sys/types.h>Zack Weinberg1-1/+7
The macros defined by <sys/sysmacros.h> are not part of POSIX nor XSI, and their names frequently collide with user code; see for instance glibc bug 19239 and Red Hat bug 130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the problem. * NEWS: Inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. * misc/sys/sysmacros.h: If __SYSMACROS_DEPRECATED_INCLUSION is defined, define major, minor, and makedev to issue deprecation warnings on use. If __SYSMACROS_DEPRECATED_INCLUSION is *not* defined, suppress previously-activated deprecation warnings for these macros and prevent subsequent inclusions of this header from having any effect. * posix/sys/types.h: Define __SYSMACROS_DEPRECATED_INCLUSION before including <sys/sysmacros.h>, and undefine it again afterward.
2016-04-14Remove union wait [BZ #19613]Florian Weimer1-50/+11
The overloading approach in the W* macros was incompatible with integer expressions of a type different from int. Applications using union wait and these macros will have to migrate to the POSIX-specified int status type.

2014-02-21Complete _BSD_SOURCE / _SVID_source followup cleanup.Joseph Myers2-7/+7
This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

2014-02-12Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers3-13/+13
This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. 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.)
