* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | 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 6694 files FOO. 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
* elf: Include libc.so.6 as main program in dependency sort (bug 20972)Florian Weimer2020-12-111-0/+36
_dl_map_object_deps always sorts the initially loaded object first during dependency sorting. This means it is relocated last in dl_open_worker. This results in crashes in IFUNC resolvers without lazy bindings if libraries are preloaded that refer to IFUNCs in libc.so.6: the resolvers are called when libc.so.6 has not been relocated yet, so references to _rtld_global_ro etc. crash. The fix is to check against the libc.so.6 link map recorded by the __libc_early_init framework, and let it participate in the dependency sort. This fixes bug 20972.
