* net: fix NULL dereferences in check_peer_redir()Eric Dumazet2012-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit d3aaeb38c40e5a6c08dd31a1b64da65c4352be36, along with dependent backports of commits: 69cce1d1404968f78b177a0314f5822d5afdbbfb 9de79c127cccecb11ae6a21ab1499e87aa222880 218fa90f072e4aeff9003d57e390857f4f35513e 580da35a31f91a594f3090b7a2c39b85cb051a12 f7e57044eeb1841847c24aa06766c8290c202583 e049f28883126c689cf95859480d9ee4ab23b7fa ] Gergely Kalman reported crashes in check_peer_redir(). It appears commit f39925dbde778 (ipv4: Cache learned redirect information in inetpeer.) added a race, leading to possible NULL ptr dereference. Since we can now change dst neighbour, we should make sure a reader can safely use a neighbour. Add RCU protection to dst neighbour, and make sure check_peer_redir() can be called safely by different cpus in parallel. As neighbours are already freed after one RCU grace period, this patch should not add typical RCU penalty (cache cold effects) Many thanks to Gergely for providing a pretty report pointing to the bug.

* [SCSI] cxgb4i v5: iscsi driverkxie@chelsio.com2010-09-051-0/+1600
Added cxgb4i iSCSI driver. This patch implements the cxgb4i iscsi connection acceleration for the open-iscsi initiator. The cxgb4i driver offers the iscsi PDU based offload: - digest insertion and verification - payload direct-placement into host memory buffer.
