Description praise.tazio 2010-11-04 19:13:34 UTC

Mysql 5.1.51 does not start with PAX mprotect enabled with the following error:

/usr/bin/my_print_defaults: error while loading shared libraries: /usr/lib/mysql/libmystrings.so.0: cannot make segment writable for relocation: Permission denied

I use a hardened profile

Reproducible: Always

Steps to Reproduce:
1. Get a Gentoo Hardened box
2. Upgrade MySQL to the latest stable.
3. Try to start MySQL.

Actual Results:  
MySQL fails to start with this error:
/usr/bin/my_print_defaults: error while loading shared libraries: /usr/lib/mysql/libmystrings.so.0: cannot make segment writable for relocation: Permission denied

Expected Results:  
MySQL starting fine.

These commands resolved the problem, I think they should be made by the ebuild:

paxctl /usr/bin/my_print_defaults -m
paxctl /usr/sbin/mysqld -m
