Date: Mon, 8 Nov 2021 20:06:34 -0500 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Kees Cook <keescook@...omium.org>, Peter Zijlstra <peterz@...radead.org>, Sasha Levin <sashal@...nel.org>, me@...in.cc, tycho@...ho.pizza, linux-hardening@...r.kernel.org Subject: [PATCH AUTOSEL 4.14 24/39] leaking_addresses: Always print a trailing newline From: Kees Cook <keescook@...omium.org> [ Upstream commit cf2a85efdade117e2169d6e26641016cbbf03ef0 ] For files that lack trailing newlines and match a leaking address (e.g. wchan[1]), the leaking_addresses.pl report would run together with the next line, making things look corrupted. Unconditionally remove the newline on input, and write it back out on output.
