Subject: [BUG] sbni: a possible sleep-in-atomic bug in sbni_close
Date: Tue, 12 Dec 2017 16:53:32 +0800 [thread overview]
Message-ID: <571ba417-9419-5e60-db59-aa642a7e9450@gmail.com> (raw)
According to drivers/net/wan/sbni.c, the driver may sleep under a spinlock.
The function call path is:
sbni_close (acquire the spinlock)
free_irq --> may sleep
I do not find a good way to fix it, so I only report.
This possible bug is found by my static analysis tool (DSAC) and checked
by my code review.
Thanks,
Jia-Ju Bai
