Subject: [PATCH 01/35] staging: brcm80211: bugfix for len==0 parameter in 3 fullmac functions
Date: Thu, 14 Jul 2011 14:28:57 -0700 [thread overview]
Message-ID: <1310678971-28952-2-git-send-email-frankyl@broadcom.com> (raw)
In-Reply-To: <1310678971-28952-1-git-send-email-frankyl@broadcom.com>
From: Roland Vossen <rvossen@broadcom.com>
Three functions use the same method to check incoming parameters. The
'len' parameter can be equal to 0 in case of a 'set' operation.
Currently these functions return an error code under that condition,
which is incorrect. The problem was introduced in recent patches in
which asserts were removed from the fullmac.
Despite this being a bug, my regression testing has not shown any problems.
