Subject: [PATCH 0/4] KASan: print output directly to stderr
Date: Mon, 11 Sep 2023 14:56:15 +0200 [thread overview]
Message-ID: <20230911125619.2782229-1-a.fatoum@pengutronix.de> (raw)
I recently hunted down a heap memory corruption and this was somewhat
complicated by KASan and dump_stack() themselves allocating memory
off the heap. This series switches them to directly write to the
consoles associated with stderr, while skipping the log.
Ahmad Fatoum (4):
ARM: unwind: don't allocate while printing stack trace
ARM64: backtrace: print stacktrace to stderr
KASan: only print to stderr
KASan: don't allocate memory while printing report
