2011-07-18netfilter: nfnetlink: add RCU in nfnetlink_rcv_msg()Eric Dumazet1-10/+30
Goal of this patch is to permit nfnetlink providers not mandate nfnl_mutex being held while nfnetlink_rcv_msg() calls them. If struct nfnl_callback contains a non NULL call_rcu(), then nfnetlink_rcv_msg() will use it instead of call() field, holding rcu_read_lock instead of nfnl_mutex Signed-off-by: Eric Dumazet <[email protected]> CC: Florian Westphal <[email protected]> CC: Eric Leblond <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>

This will get us closer to being able to do "neigh stuff" completely independent of the underlying dst_entry for protocols (ipv4/ipv6) that wish to do so. We will also be able to make dst entries neigh-less. Signed-off-by: David S. Miller <[email protected]>

2011-07-15svcrpc: fix list-corrupting race on nfsd shutdownJ. Bruce Fields1-5/+6
After commit 3262c816a3d7fb1eaabce633caa317887ed549ae "[PATCH] knfsd: split svc_serv into pools", svc_delete_xprt (then svc_delete_socket) no longer removed its xpt_ready (then sk_ready) field from whatever list it was on, noting that there was no point since the whole list was about to be destroyed anyway. That was mostly true, but forgot that a few svc_xprt_enqueue()'s might still be hanging around playing with the about-to-be-destroyed list, and could get themselves into trouble writing to freed memory if we left this xprt on the list after freeing it. (This is actually functionally identical to a patch made first by Ben Greear, but with more comments.)

2011-07-15nfsd: Remove deprecated nfsctl system call and related code.NeilBrown1-78/+0
As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code. These should be cleaned out too, probably in the next merge window. Signed-off-by: NeilBrown <[email protected]> Signed-off-by: J. Bruce Fields <[email protected]>
2011-07-15mac80211: be more careful in suspend/resumeJohannes Berg2-26/+31
When suspending with all netdevs down, the device is stopped but we still call a number of driver callbacks that the driver might not expect. The same happens during resume, we might call a few callbacks without starting the driver. Fix this by checking open_count around more things and exiting quickly if it is 0. Also, while at this I noticed that the coverage class isn't reprogrammed after resume, so add that. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: John W.

2011-07-14net: remove NETIF_F_ALL_TX_OFFLOADSMichał Mirosław1-1/+5
There is no software fallback implemented for SCTP or FCoE checksumming, and so it should not be passed on by software devices like bridge or bonding. For VLAN devices, this is different. First, the driver for underlying device should be prepared to get offloaded packets even when the feature is disabled (especially if it advertises it in vlan_features). Second, devices under VLANs do not get replaced without tearing down the VLAN first. This fixes a mess I accidentally introduced while converting bonding to ndo_fix_features. NETIF_F_SOFT_FEATURES are removed from BOND_VLAN_FEATURES because they are unused as of commit 712ae51afd. Signed-off-by: Michał Mirosław <[email protected]> Signed-off-by: David S.

2011-07-14net: sctp: fix checksum marking for outgoing packetsMichał Mirosław1-11/+8
Packets to devices without NETIF_F_SCTP_CSUM (including NETIF_F_NO_CSUM) should be properly checksummed because the packets can be diverted or rerouted after construction. This still leaves packets diverted from NETIF_F_SCTP_CSUM-enabled devices with broken checksums. Fixing this needs implementing software offload fallback in networking core. For users of sctp_checksum_disable, skb->ip_summed should be left as CHECKSUM_NONE and not CHECKSUM_UNNECESSARY as per include/linux/skbuff.h.

2011-07-13mac80211: allow driver to disconnect after resumeJohannes Berg6-6/+63
In WoWLAN, devices may use crypto keys for TX/RX and could also implement GTK rekeying. If the driver isn't able to retrieve replay counters and similar information from the device upon resume, or if the device isn't responsive due to platform issues, it isn't safe to keep the connection up as GTK rekey messages from during the sleep time could be replayed against it. The only protection against that is disconnecting from the AP. Modifying mac80211 to do that while it is resuming would be very complex and invasive in the case that the driver requires a reconfig, so do it after it has resumed completely. In that case, however, packets might be replayed since it can then only happen after TX/RX are up again, so mark keys for interfaces that need to disconnect as "tainted" and drop all packets that are sent or received with those keys.
