2021-09-16Fix build-many-glibcs.py --strip for installed library renamingJoseph Myers1-9/+7
The renaming of installed shared libraries to use the SONAME directly rather than linking to a versioned name stopped build-many-glibcs.py --strip (used to facilitate comparing binaries before and after changes that aren't meant to change any generated code in installed glibc shared libraries) from stripping most of the installed shared libraries, because it stripped only the *.so names. Fix it to strip *.so* names instead and to detect the case of linker scripts using grep instead of hardcoding particular files that are linker scripts. Tested with build-many-glibcs.py --strip.

2021-09-03Remove "Contributed by" linesSiddhesh Poyarekar4-4/+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>
2021-09-03Port shared code information from the wikiSiddhesh Poyarekar1-0/+70
Since the shared code now has special status with respect to copyrights, port them into a more structured format in the source tree and add a python function that parses and returns a dictionary with the information. I need this to exclude these files from the Contributed-by changes and I reckon it would be useful to know these files for future tooling. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

2021-06-29nptl_db: Re-use the ELF-to-abilist converter for ABI checkingFlorian Weimer1-1/+1
The previous approach uses readelf -DWs, which does not produce a stable output format (older binutils versions do not include symbol version information). This commit re-uses scripts/abilist.awk with a tweak to include GLIBC_PRIVATE symbols. This awk script is based on objdump -T output, which appears to be stable over time.

2021-06-02Add libc ABI extension kludge for baseline-violating libdl symbolsFlorian Weimer1-1/+25
Some targets have a GLIBC_2.0 baseline for libdl, while using GLIBC_2.2 for libc. This means that the generated libc.map file does not have any version nodes for GLIBC_2.0 or GLIBC_2.1. However, moving symbols from libdl into libc needs such version nodes. (Future symbol moves from librt will need this as well.) This kludge is only necessary for symbols predating GLIBC_2.2 because the affected targets use GLIBC_2.2 as the baseline for libc. Given the small number and fixed set of affected architectures, no generic mechanism is implemented, and instead the map file fragment is hard-coded in scripts/versions.mk. The compat_symbol macro already emits the appropriate version strings, so no adjustments are needed there. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2021-06-02scripts/versions.awk: Add local: * to all version nodesFlorian Weimer1-5/+1
This requires that all exported symbol versions are listed in Versions files. It results in more consistent behavior across architectures because previously, symbols could be exported via explicit versioned_symbol and compat_symbol macros if the version node existed in some Versions file (without listing the symbol), and it was not the base version for the library (which already had the local: * directive).

2021-01-21elf: Avoid RELATIVE relocs in __tunables_initSzabolcs Nagy1-1/+11
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. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2021-01-21elf: Make the tunable struct definition internal onlySzabolcs Nagy1-1/+3
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>
2021-01-11install: Replace scripts/output-format.sed with objdump -f [BZ #26559]Fangrui Song1-35/+0
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.

2021-01-02Update copyright dates not handled by scripts/update-copyrights.Paul Eggert1-1/+1
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).
2021-01-02Update copyright dates with scripts/update-copyrightsPaul Eggert27-27/+27

I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

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).

2020-07-07signal: Move sys_errlist to a compat symbolAdhemerval Zanella1-2/+1
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.
