* 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
* Add tests for Safe-LinkingEyal Itkin2020-04-031-0/+179
Adding the test "tst-safe-linking" for testing that Safe-Linking works as expected. The test checks these 3 main flows: * tcache protection * fastbin protection * malloc_consolidate() correctness As there is a random chance of 1/16 that of the alignment will remain correct, the test checks each flow up to 10 times, using different random values for the pointer corruption. As a result, the chance for a false failure of a given tested flow is 2**(-40), thus highly unlikely. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
