* Always define __USE_TIME_BITS64 when 64 bit time_t is usedAdhemerval Zanella2024-04-025-21/+21
| | | | | | | | | | | | | | | | | | | | 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>
* Refer to C23 in place of C2X in glibcJoseph Myers2024-02-011-4/+4
| | | | | | | | | | | | | | | WG14 decided to use the name C23 as the informal name of the next revision of the C standard (notwithstanding the publication date in 2024). Update references to C2X in glibc to use the C23 name. This is intended to update everything *except* where it involves renaming files (the changes involving renaming tests are intended to be done separately). In the case of the _ISOC2X_SOURCE feature test macro - the only user-visible interface involved - support for that macro is kept for backwards compatibility, while adding _ISOC23_SOURCE. Tested for x86_64.

* Move libc_freeres_ptrs and libc_subfreeres to hidden/weak functionsAdhemerval Zanella Netto2023-03-272-2/+6
| | | | | | | | | | | | | | | | | | | | They are both used by __libc_freeres to free all library malloc allocated resources to help tooling like mtrace or valgrind with memory leak tracking. The current scheme uses assembly markers and linker script entries to consolidate the free routine function pointers in the RELRO segment and to be freed buffers in BSS. This patch changes it to use specific free functions for libc_freeres_ptrs buffers and call the function pointer array directly with call_function_static_weak.

This fixes a problem where "1986-04-28 00:00 EDT" was rejected when TZ="America/Indianapolis" because the nearest DST timestamp occurred in 1970, a temporal distance too great for the old heuristic. This also also narrows the search a bit, which is a minor performance win.

* timezone: handle truncated timezones from tzcode-2021d and later (BZ #28707)Hans-Peter Nilsson2021-12-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a timezone file with a truncated starting time, generated by the zic in IANA tzcode-2021d a.k.a. tzlib-2021d (also in tzlib-2021e; current as of this writing), glibc asserts in __tzfile_read (on e.g. tzset() for this file) and you may find lines matching "tzfile.c:435: __tzfile_read: Assertion `num_types == 1' failed" in your syslog. One example of such a file is the tzfile for Asuncion generated by tzlib-2021e as follows, using the tzlib-2021e zic: "zic -d DEST -r @1546300800 -L /dev/null -b slim SOURCE/southamerica". Note that in its type 2 header, it has two entries in its "time-types" array (types), but only one entry in its "transition types" array (type_idxs). This is valid and expected already in the published RFC8536, and not even frowned upon: "Local time for timestamps before the first transition is specified by the first time type (time type 0)" ... "every nonzero local time type index SHOULD appear at least once in the transition type array". Note the "nonzero ... index". Until the 2021d zic, index 0 has been shared by the first valid transition but with 2021d it's separate, set apart as a placeholder and only "implicitly" indexed. (A draft update of the RFC mandates that the entry at index 0 is a placeholder in this case, hence can no longer be shared.) * time/tzfile.c (__tzfile_read): Don't assert when no transitions are found.

I did not see it on other kernels, for instance 5.11 and 4.15. To avoid trying to guess the resolution used, do not check the nanosecond internal values for the specific timers.

* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-036-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* time: Fix overflow itimer tests on 32-bit systemsStafford Horne2021-08-151-2/+2
| | | | | | | | | | | | | | | | | | | | On the port of OpenRISC I am working on and it appears the rv32 port we have sets __TIMESIZE == 64 && __WORDSIZE == 32. This causes the size of time_t to be 8 bytes, but the tv_sec in the kernel is still 32-bit causing truncation. The truncations are unavoidable on these systems so skip the testing/failures by guarding with __KERNEL_OLD_TIMEVAL_MATCHES_TIMEVAL64. Also, futher in the tests and in other parts of code checking for time_t overflow does not work on 32-bit systems when time_t is 64-bit. As suggested by Adhemerval, update the in_time_t_range function to assume 32-bits by using int32_t. This also brings in the header for stdint.h so we can update other usages of __int32_t to int32_t as suggested by Adhemerval. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

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.

* Do not declare asctime_r and ctime_r for C2XJoseph Myers2021-05-181-2/+2
| | | | | | | | | | | | | | | | | ISO C2X added the asctime_r, ctime_r, gmtime_r and localtime_r functions from POSIX. It's now removed asctime_r and ctime_r again, reflecting that they are marked obsolescent in POSIX; update glibc's time.h accordingly. The same change that removed those two functions from C2X also marked asctime and ctime as deprecated (reflecting how POSIX shows them as obsolescent), i.e. using the [[deprecated]] attribute in the prototypes shown in C2X. It's less clear if we should explicitly deprecate those functions like that in the glibc headers; this patch does nothing regarding such a deprecation (there's no normative requirement from C2X showing the functions as deprecated). Tested for x86_64 and x86.
* Add C2X timespec_getresJoseph Myers2021-05-176-2/+96
| | | | | | | | | | | | | | | | | | | ISO C2X adds a timespec_getres function alongside the C11 timespec_get, with functionality similar to that of POSIX clock_getres (including allowing a NULL pointer to be passed to the function). Implement this function for glibc, similarly to the implementation of timespec_get. This includes a basic test like that of timespec_get, but no documentation in the manual, given that TIME_UTC and timespec_get aren't documented in the manual at all. The handling of 64-bit time follows that in timespec_get; people maintaining patch series for 64-bit time will need to update them accordingly (to export __timespec_getres64, redirect calls in time.h and run the test for _TIME_BITS=64). Tested for x86_64 and x86, and (previous version; only testcase differs) with build-many-glibcs.py.
