2011-05-13qlcnic: FW dump supportAnirban Chakraborty6-9/+774

2011-05-13be2net: fix mbox polling for signal receptionSathya Perla1-2/+1
Sending mbox cmds require multiple steps of writing to the DB register and polling for an ack. Gettting interrupted in the middle by a signal breaks the mbox protocol. Use msleep() to not get interrupted. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-13ethtool: Added support for FW dumpAnirban Chakraborty2-0/+121
Added code to take FW dump via ethtool. Dump level can be controlled via setting the dump flag. A get function is provided to query the current setting of the dump flag. Dump data is obtained from the driver via a separate get function. Changes from v3: Fixed buffer length issue in ethtool_get_dump_data function. Updated kernel doc for ethtool_dump struct and get_dump_flag function. Changes from v2: Provided separate commands for get flag and data. Check for minimum of the two buffer length obtained via ethtool and driver and use that for dump buffer Pass up the driver return error codes up to the caller. Added kernel doc comments.

2011-05-13wl12xx: prevent scheduling while suspending (WoW enabled)Eliad Peller3-0/+72
When WoW is enabled, the interface will stay up and the chip will be powered on, so we have to flush/cancel any remaining work, and prevent the irq handler from scheduling a new work until the system is resumed. Add 2 new flags: * WL1271_FLAG_SUSPENDED - the system is (about to be) suspended. * WL1271_FLAG_PENDING_WORK - there is a pending irq work which should be scheduled when the system is being resumed. In order to wake-up the system while getting an irq, we initialize the device as wakeup device, and calling pm_wakeup_event() upon getting the interrupt (while the system is about to be suspended) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-05-13ipv4: Elide use of rt->rt_dst in ip_forward()David S. Miller1-1/+1
No matter what kind of header mangling occurs due to IP options processing, rt->rt_dst will always equal iph->daddr in the packet. So we can safely use iph->daddr instead of rt->rt_dst here. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-05-13ipv4: Simplify iph->daddr overwrite in ip_options_rcv_srr().David S. Miller1-1/+1

2011-05-13ipv6: restore correct ECN handling on TCP xmitSteinar H. Gunderson1-3/+13
Since commit e9df2e8fd8fbc9 (Use appropriate sock tclass setting for routing lookup) we lost ability to properly add ECN codemarks to ipv6 TCP frames. It seems like TCP_ECN_send() calls INET_ECN_xmit(), which only sets the ECN bit in the IPv4 ToS field (inet_sk(sk)->tos), but after the patch, what's checked is inet6_sk(sk)->tclass, which is a completely different field.

2011-05-13ipvs: Remove all remaining references to rt->rt_{src,dst}Julian Anastasov3-51/+54
Remove all remaining references to rt->rt_{src,dst} by using dest->dst_saddr to cache saddr (used for TUN mode). For ICMP in FORWARD hook just restrict the rt_mode for NAT to disable LOCALNODE. All other modes do not allow IP_VS_RT_MODE_RDR, so we should be safe with the ICMP forwarding. Using cp->daddr as replacement for rt_dst is safe for all modes except BYPASS, even when cp->dest is NULL because it is cp->daddr that is used to assign cp->dest for sync-ed connections.

2011-05-13net: group FCoE related feature flagsYi Zou1-1/+5
Michał Mirosław's patch (http://patchwork.ozlabs.org/patch/94421/) fixes the issue (http://patchwork.ozlabs.org/patch/94188/) about not populating FCoE related flags correctly on vlan devices. However, only NETIF_F_FCOE_CRC is part of the NETIF_F_ALL_TX_OFFLOADS right now, where weed NETIF_F_FCOE_MTU and NETIF_F_FSO as well. Therefore, add NETIF_F_ALL_FCOE to indicate feature flags used by FCoE TX offloads. These include NETIF_F_FCOE_CRC, NETIF_F_FCOE_MTU, and NETIF_F_FSO and add them to be part of NETIF_F_ALL_TX_OFFLOADS. This would eventually make sure all FCoE needed flags are populated properly to vlan devices. Signed-off-by: Yi Zou <yi.zou@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-05-13net: Fix vlan_features propagationMichał Mirosław1-2/+4
Fix VLAN features propagation for devices which change vlan_features. For this to work, driver needs to make sure netdev_features_changed() gets called after the change (it is e.g. after ndo_set_features()). Side effect is that a user might request features that will never be enabled on a VLAN device. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.

When removing last vlan from a device, garp_uninit_applicant() calls synchronize_rcu() to make sure no user can still manipulate struct garp_applicant before we free it. Use call_rcu() instead, as a step to further net_device dismantle optimizations.

2011-05-13l2tp: fix potential rcu raceEric Dumazet1-6/+4
While trying to remove useless synchronize_rcu() calls, I found l2tp is indeed incorrectly using two of such calls, but also bumps tunnel refcount after list insertion. tunnel refcount must be incremented before being made publically visible by rcu readers. This fix can be applied to 2.6.35+ and might need a backport for older kernels, since things were shuffled in commit fd558d186df2c (l2tp: Split pppol2tp patch into separate l2tp and ppp parts) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Paul E.

2011-05-12cfg80211/mac80211: avoid bounce back mac->cfg->mac on sched_scan_stoppedLuciano Coelho8-30/+43
When sched_scan_stopped was called by the driver, mac80211 calls cfg80211, which in turn was calling mac80211 back with a flag "driver_initiated". This flag was used so that mac80211 would do the necessary cleanup but would not call the driver. This was enough to prevent the bounce back between the driver and mac80211, but not between mac80211 and cfg80211. To fix this, we now do the cleanup in mac80211 before calling cfg80211. To help with locking issues, the workqueue was moved from cfg80211 to mac80211.
