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".
