Subject: [Patch] net: fix a wrong assignment in skb_split()
Date: Wed, 20 Feb 2013 16:51:30 +0800 [thread overview]
Message-ID: <1361350290-28581-1-git-send-email-amwang@redhat.com> (raw)
commit c9af6db4c11ccc6c3e7f1 (net: Fix possible wrong checksum generation)
has a suspicous piece:
- skb_shinfo(skb1)->gso_type = skb_shinfo(skb)->gso_type;
-
+ skb_shinfo(skb)->tx_flags = skb_shinfo(skb1)->tx_flags & SKBTX_SHARED_FRAG;
skb1 is the new skb, therefore should be on the left side of the assignment.
This patch fixes it.
