Lukasz Majewski	496e36f225	tst: Extend cross-test-ssh.sh to specify if target date can be altered This code adds new flag - '--allow-time-setting' to cross-test-ssh.sh script to indicate if it is allowed to alter the date on the system on which tests are executed. This change is supposed to be used with test systems, which use virtual machines for testing. The GLIBC_TEST_ALLOW_TIME_SETTING env variable is exported to the remote environment on which the eligible test is run and brings no functional change when it is not.

Florian Weimer	418f5783d9	build-many-glibcs.py: Use make -O for more consistent log output The -O option avoids interleaving (e.g.) compiler error messages with other build messages, and makes attribution of messages to commands easier. According to my tests, the impact on build time is within the noise.	5 years ago

Szabolcs Nagy	bfe04789a8	elf: Avoid RELATIVE relocs in __tunables_init With static pie linking pointers in the tunables list need RELATIVE relocs since the absolute address is not known at link time. We want to avoid relocations so the static pie self relocation can be done after tunables are initialized. This is a simple fix that embeds the tunable strings into the tunable list instead of using pointers. It is possible to have a more compact representation of tunables with some additional complexity in the generator and tunable parser logic. Such optimization will be useful if the list of tunables grows. There is still an issue that tunables_strdup allocates and the failure handling code path is sufficiently complex that it can easily have RELATIVE relocations. It is possible to avoid the early allocation and only change environment variables in a setuid exe after relocations are processed. But that is a bigger change and early failure is fatal anyway so it is not as critical to fix right away. This is bug 27181.

Szabolcs Nagy	058308066c	elf: Make the tunable struct definition internal only The representation of the tunables including type information and the tunable list structure are only used in the implementation not in the tunables api that is exposed to usage within glibc. This patch moves the representation related definitions into the existing dl-tunable-types.h and uses that only for implementation. The tunable callback and related types are moved to dl-tunables.h because they are part of the tunables api. This reduces the details exposed in the tunables api so the internals are easier to change. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>	5 years ago
Fangrui Song	87d583c6e8	install: Replace scripts/output-format.sed with objdump -f [BZ #26559 ] GNU ld and gold have supported --print-output-format since 2011. glibc requires binutils>=2.25 (2015), so if LD is GNU ld or gold, we can assume the option is supported. lld is by default a cross linker supporting multiple targets. It auto detects the file format and does not need OUTPUT_FORMAT. It does not support --print-output-format. By parsing objdump -f, we can support all the three linkers.

Paul Eggert	9fcdec7386	Update copyright dates not handled by scripts/update-copyrights. I've updated copyright dates in glibc for 2021. 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 2021 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).	5 years ago

Petr Vorel	5500cdba40	Remove --enable-obsolete-rpc configure flag Sun RPC was removed from glibc. This includes rpcgen program, librpcsvc, and Sun RPC headers. Also test for bug #20790 was removed (test for rpcgen). Backward compatibility for old programs is kept only for architectures and ABIs that have been added in or before version 2.28. libtirpc is mature enough, librpcsvc and rpcgen are provided in rpcsvc-proto project. NOTE: libnsl code depends on Sun RPC (installed libnsl headers use installed Sun RPC headers), thus --enable-obsolete-rpc was a dependency for --enable-obsolete-nsl (removed in a previous commit).

Petr Vorel	ae7a94e5e3	Remove --enable-obsolete-nsl configure flag this means that always libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.	6 years ago
Adhemerval Zanella	f13d260190	signal: Move sys_errlist to a compat symbol The symbol is deprecated by strerror since its usage imposes some issues such as copy relocations. Its internal name is also changed to _sys_errlist_internal to avoid static linking usage. The compat code is also refactored by removing the over enginered errlist-compat.c generation from manual entried and extra comment token in linker script file. It disantangle the code generation from manual and simplify both Linux and Hurd compat code. The definitions from errlist.c are moved to errlist.h and a new test is added to avoid a new errno entry without an associated one in manual. Checked on x86_64-linux-gnu and i686-linux-gnu.

Florian Weimer	076f09afba	Linux: Remove <sys/sysctl.h> and the sysctl function Linux 5.5 remove the system call in commit 61a47c1ad3a4dc6882f01ebdc88138ac62d0df03 ("Linux: Remove <sys/sysctl.h>"). Therefore, the compat function is just a stub that sets ENOSYS. Due to SHLIB_COMPAT, new ports will not add the sysctl function anymore automatically. x32 already lacks the sysctl function, so an empty sysctl.c file is used to suppress it.
