Subject: isdn: pcbit: another off-by-one issue?
Date: Wed, 10 Jun 2015 21:50:53 +0200	[thread overview]
Message-ID: <87381zqr4y.fsf@rasmusvillemoes.dk> (raw)

Hi Dan

You were last to touch drivers/isdn/pcbit/drv.c (7bcc6738eef), but I
think there may still be an off-by-one in pcbit_set_msn: At the end of
the loop, sp is incremented by len, but if the string contained a comma,
sp will now point at that. At that point, we seem to be stuck in an
infinite loop where we'll always get cp==sp and len==0, until we run out
of memory.

Am I reading this completely wrong?

Rasmus
