Revision 5b5a60da281c767196427ce8144deae6ec46b389 authored by Olaf Kirch on 24 June 2007, 06:11:52 UTC, committed by David S. Miller on 24 June 2007, 06:11:52 UTC
Having walked through the entire skbuff, skb_seq_read would leave the last fragment mapped. As a consequence, the unwary caller would leak kmaps, and proceed with preempt_count off by one. The only (kind of non-intuitive) workaround is to use skb_seq_read_abort. This patch makes sure skb_seq_read always unmaps frag_data after having cycled through the skb's paged part.
