* Documentation for OpenRISC portStafford Horne2022-01-052-0/+10
| | | | | | | | | | | | | | | | OpenRISC architecture specification: https://raw.githubusercontent.com/openrisc/doc/master/openrisc-arch-1.3-rev1.pdf Currently the port as of the 2022-01-03 rebasing there are no known architecture specific test failures.

* or1k: Build InfrastructureStafford Horne2022-01-059-0/+63
| | | | | | | | | | Here we define the minumum linux kernel version at 5.4.0, as that is the long term support version where 32-bit architectures start to support 64-bit time API's. The OpenRISC kernel had some bugs up until version 5.8 which caused issues with glibc fork/clone, they have been backported to 5.4 but not previous versions.

* elf: Also try DT_RUNPATH for LD_AUDIT dlopen [BZ #28455]H.J. Lu2022-01-043-3/+24
| | | | | | | | | | | DT_RUNPATH is only used to find the immediate dependencies of the executable or shared object containing the DT_RUNPATH entry. Update LD_AUDIT dlopen call to try the DT_RUNPATH entry of the executable. Add tst-audit14a, which is copied from tst-audit14, to DT_RUNPATH and build tst-audit14 with -Wl,--disable-new-dtags to test DT_RPATH. This partially fixes BZ #28455.

* Update copyright dates not handled by scripts/update-copyrights.Paul Eggert2022-01-0123-23/+23
| | | | | | | | | | | | | | I've updated copyright dates in glibc for 2022. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files. As well as the usual annual updates, mainly dates in --version output (minus csu/version.c which previously had to be handled manually but is now successfully updated by update-copyrights), there is a small change to the copyright notice in NEWS which should let NEWS get updated automatically next year. Please remember to include 2022 in the dates for any new files added in future (which means updating any existing uncommitted patches you have that add new files to use the new copyright dates in them).
* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-0111764-11771/+11770
| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

* hurd: Bump BRK_START to 0x20000000Samuel Thibault2021-12-311-1/+1
| | | | | By nowadays uses, 256MiB is not that large for the program+libraries. Let's push the heap further to leave room for e.g. clang.
* hurd: Avoid overzealous shared objects constraintsSamuel Thibault2021-12-312-3/+3
| | | | | | | | | | | 407765e9f24f ("hurd: Fix ELF_MACHINE_USER_ADDRESS_MASK value") switched ELF_MACHINE_USER_ADDRESS_MASK from 0xf8000000UL to 0xf0000000UL to let libraries etc. get loaded at 0x08000000. But ELF_MACHINE_USER_ADDRESS_MASK is actually only meaningful for the main program anyway, so keep it at 0xf8000000UL to prevent the program loader from putting ld.so beyond 0x08000000. And conversely, drop the use of ELF_MACHINE_USER_ADDRESS_MASK for shared objects, which don't need any constraints since the program will have already be loaded by then.
* time: Refactor timesize.h for some ABIsAdhemerval Zanella2021-12-314-11/+15
| | | | | | | | | Commit a4b413135535c83a changed default __TIMESIZE to 64, however it added sub-architecture timesize.h for powerpc, s390, and sparc. Also simplify mips by removing _MIPS_SIM usage (which would require to add sgidefs inclusion.
* hurd: Make getrandom a stub inside the random translatorSamuel Thibault2021-12-311-0/+13
| | | | | | glibc uses /dev/urandom for getrandom(), and from version 2.34 malloc initialization uses it. We have to detect when we are running the random translator itself, in which case we can't read ourself.
* open64: Force O_LARGEFILE on all architecturesStafford Horne2021-12-314-29/+4
| | | | | | | | | | | | | | | | When running tests on OpenRISC which has 32-bit wordsize but 64-bit timesize it was found that O_LARGEFILE is not being set when calling open64. For 64-bit architectures the O_LARGEFILE flag is generally implied by the kernel according to force_o_largefile. However, for 32-bit architectures this is not done. For this patch we unconditionally now set the O_LARGEFILE flag for open64 class syscalls as there is no harm in doing so. Tested on the OpenRISC the build works and timezone/tst-tzset passes which was failing before. I would expect this also would fix arc. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* 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.
