Date: Tue, 26 Jul 2016 23:52:22 +0200 From: Michal Marek <mmarek@...e.com> To: Kees Cook <keescook@...omium.org> Cc: linux-kernel@...r.kernel.org, Ingo Molnar <mingo@...nel.org>, x86@...nel.org, linux-kbuild@...r.kernel.org Subject: Re: [PATCH v2] kbuild: Abort build on bad stack protector flag Dne 26.7.2016 v 23:26 Kees Cook napsal(a): > Before, the stack protector flag was sanity checked before .config had > been reprocessed. This meant the build couldn't be aborted early, and > only a warning could be emitted followed later by the compiler blowing > up with an unknown flag. This has caused a lot of confusion over time, > so this splits the flag selection from sanity checking and performs the > sanity checking after the make has been restarted from a reprocessed > .config, so builds can be aborted as early as possible now. > > Additionally moves the x86-specific sanity check to the same location, > since it suffered from the same warn-then-wait-for-compiler-failure > problem. > > Signed-off-by: Kees Cook <keescook@...omium.org> > --- > v2: > - fix use of SRCARCH, mmarek > - simplify stackp-check usage, mmarek Applied to kbuild.git#kbuild.
