Subject: AUDIT: Fix reported length of audit messages.
X-Git-Tag: v2.6.14-rc2~49^2~71
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=8c5aa40c94ef8bb7f7da95ecd5942e2d20fc3c9d;p=~emulex%2Finfiniband.git

AUDIT: Fix reported length of audit messages.

We were setting nlmsg_len to skb->len, but we should be subtracting
the size of the header.
