Description Peter Alfredsen (RETIRED) gentoo-dev 2009-02-17 21:58:51 UTC
In gcc-4.3.3, -D_FORTIFY_SOURCE=2 and -Wformat-is added automagically to C[XX]FLAGS
  - Please file a NEW bug for each package affected by this change and make it BLOCK this one.
  - Do NOT use this bug for issues with >=GCC 4.3.3 itself.  File a new bug and
assign it to toolchain.

Hardened has already done this for some time, so a few bugs have been moved from the gcc-4.3 tracker to this one to keep better track of things.
Comment 1 SpanKY gentoo-dev 2009-02-24 07:29:54 UTC
any package broken by -Wformat-security is broken regardless ... no package should be building with -Werror and afaik, that's the only way to trigger a failure with that

Comment 4 SpanKY gentoo-dev 2014-09-11 05:31:55 UTC
i don't think any of these format-security bugs are useful.  if you want to convince upstream to make their code base nice, then that'd be great.  but i see no real value in Gentoo carrying patches, and i'm inclined to start closing them as UPSTREAM.

I didn't even know this tracker was here.  As Peter said, hardened has lived with this a long time without too much difficulty and I really don't want to see a bunch of patches causing an unnecessary maintenance burndon.

I say, let's close these upstream and suggest using append-cppflags if necessary to change the -D_FORTIFY_SOURCE=2.  As already stated -Wformat-security will just warn.

Please go ahead.  The bugspam is getting excessive and will continue as long as this bug is open.
Comment 7 Ryan Hill (RETIRED) gentoo-dev 2015-08-05 06:08:30 UTC
We could add -Wformat-security to portage's post-build qa checks.  This would both raise its visibility and tell people that upstream is the proper place to report any warnings to.
Comment 8 Sergei Trofimovich (RETIRED) gentoo-dev 2019-12-23 13:30:51 UTC
Gentoo carries -D_FORTIFY_SOURCE=2/-Wformat-security patches for a long while including every stable compiler. Closing thus bug. Feel free to create a separate tracker for -Werror=format-security failures. Those don't block gcc stabilization.
