Subject: [PATCH v2 0/2] watchdog: pika_wdt: portability and timer lifecycle fixes
Date: Tue, 2 Jun 2026 21:02:28 -0700 [thread overview]
Message-ID: <20260603040230.318998-1-rosenp@gmail.com> (raw)
Replace ppc4xx-specific MMIO accessors with portable helpers and
fix two high-severity timer bugs: a UAF on module exit (timer
fires after iounmap) and a close race that defeats the watchdog
reset on unexpected daemon termination.
v2: fix preexisting issues
Rosen Penev (2):
watchdog: pika_wdt: fix timer leak and close race
watchdog: pika_wdt: replace in_be32/out_be32 with
ioread32be/iowrite32be
