Re: RFC: Increase _FORTIFY_SOURCE level to 3

[Genes Lists <lists@xxxxxxxxxxxx>]

Follow up to my previous note

It looks fairly straightforward to identify which applications need to 
remain on level 2 by checking binaries for those using the 
malloc_usable_size() call.

e.g.

$ nm -uD /usr/lib/systemd/systemd-networkd |grep malloc_usable
      U malloc_usable_size@GLIBC_2.2.5
