Or just do:
echo 0 > /proc/sys/fs/protected_hardlinks
echo 0 > /proc/sys/fs/protected_symlinks
(or put the equivalent in /etc/sysctl.conf).
There is a **very** detailed description of the design decision behind
this change (which went in as of 3.6) in the commit description. See:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=800179c9b8a1e796e441674776d11cd4c05d61d7
In any case, it's "working as designed".
