2010-06-13e1000: Fix message logging defectJoe Perches
commit 675ad47375c76a7c3be4ace9554d92cd55518ced removed the capability to use ethtool.set_msglevel to control the types of messages emitted by the driver. That commit should probably be reverted. If not, then this patch fixes a message logging defect introduced by converting a printk without KERN_<level> to e_info. This also reduces text by about 200 bytes.

2010-06-13ixgbe: fix for race with 8259(8|9) during shutdownDon Skidmore
There is a small window where the watchdog could be running as the interface is brought down on a NIC with two ports wired back to back. If ixgbe_update_status is then called can lead to a panic. This patch allows the update to bail if we are in that condition. This issue was orignally reported and fix proposed by Akihiko Saitou.

2010-06-10net: deliver skbs on inactive slaves to exact matchesJohn Fastabend
Currently, the accelerated receive path for VLAN's will drop packets if the real device is an inactive slave and is not one of the special pkts tested for in skb_bond_should_drop(). This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

2010-06-09gianfar: Revive the driver for eTSEC devices (disable timestamping)Anton Vorontsov
Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add hardware RX timestamping support"), the driver no longer works on at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more boards as well). That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.

When we receive a deauthentication frame before having successfully associated, we neither print a message nor abort assocation. The former makes it hard to debug, while the latter later causes a warning in cfg80211 when, as will typically be the case, association timed out. This warning was reported by many, e.g. in https://bugzilla.kernel.org/show_bug.cgi?id=15981, but I couldn't initially pinpoint it.

2010-06-06r8169: fix random mdio_write failuresTimo Teräs
Some configurations need delay between the "write completed" indication and new write to work reliably. Realtek driver seems to use longer delay when polling the "write complete" bit, so it waits long enough between writes with high probability (but could probably break too). This patch adds a new udelay to make sure we wait unconditionally some time after the write complete indication. This caused a regression with XID 18000000 boards when the board specific phy configuration writing many mdio registers was added in commit 2e955856ff (r8169: phy init for the 8169scd). Some of the configration mdio writes would almost always fail, and depending on failure might leave the PHY in non-working state.

2010-06-05iwlwifi: move sysfs_create_group to post request firmwareEmmanuel Grumbach
Move the sysfs_create_group to iwl_ucode_callback after we have safely got the firmware. The motivation to do this comes from a warning from lockdep which detected that we request priv->mutex while holding s_active during a sysfs request (show_statistics in the example copy pasted). The reverse order exists upon request_firmware: request_firmware which is a sysfs operation that requires s_active is run under priv->mutex. This ensures that we don't get sysfs request before we finish to request the firmware, avoiding this deadlock. ======================================================= [ INFO: possible circular locking dependency detected ] ------------------------------------------------------- cat/2595 is trying to acquire lock: (&priv->mutex){+.+.+.}, at: [<facfa598>] show_statistics+0x48/0x100 [iwlagn] but task is already holding lock: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (s_active){++++.+}: [<c0489b74>] __lock_acquire+0xc44/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c0581499>] sysfs_addrm_finish+0xe9/0x180 [<c057f64a>] sysfs_hash_and_remove+0x4a/0x80 [<c05829d4>] sysfs_remove_group+0x44/0xd0 [<c0714b75>] dpm_sysfs_remove+0x15/0x20 [<c070dac8>] device_del+0x38/0x170 [<c070dc1e>] device_unregister+0x1e/0x60 [<c071838d>] _request_firmware+0x29d/0x550 [<c07186c7>] request_firmware+0x17/0x20 [<fad01bf1>] iwl_mac_start+0xb1/0x1230 [iwlagn] [<fa46ba06>] ieee80211_open+0x436/0x6f0 [mac80211] [<c0808cd2>] dev_open+0x92/0xf0 [<c0808b2b>] dev_change_flags+0x7b/0x190 [<c08148e8>] do_setlink+0x178/0x3b0 [<c0815169>] rtnl_setlink+0xf9/0x130 [<c081453b>] rtnetlink_rcv_msg+0x1bb/0x1f0 [<c0827ce6>] netlink_rcv_skb+0x86/0xa0 [<c081436c>] rtnetlink_rcv+0x1c/0x30 [<c08279c3>] netlink_unicast+0x263/0x290 [<c0828768>] netlink_sendmsg+0x1c8/0x2a0 [<c07f85fd>] sock_sendmsg+0xcd/0x100 [<c07f964d>] sys_sendmsg+0x15d/0x290 [<c07f9e6b>] sys_socketcall+0xeb/0x2a0 [<c040ad9f>] sysenter_do_call+0x12/0x38 -> #0 (&priv->mutex){+.+.+.}: [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c048a1ed>] lock_acquire+0x8d/0x110 [<c08bb358>] __mutex_lock_common+0x58/0x470 [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c052880f>] vfs_read+0x9f/0x190 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 other info that might help us debug this: 3 locks held by cat/2595: #0: (&buffer->mutex){+.+.+.}, at: [<c057fe25>] sysfs_read_file+0x35/0x190 #1: (s_active){++++.+}, at: [<c0580ecd>] sysfs_get_active_two+0x2d/0x50 #2: (s_active){++++.+}, at: [<c0580ebd>] sysfs_get_active_two+0x1d/0x50 stack backtrace: Pid: 2595, comm: cat Not tainted 2.6.33-tp-rc4 #2 Call Trace: [<c08b99ab>] ? printk+0x1d/0x22 [<c0487752>] print_circular_bug+0xc2/0xd0 [<c0489f84>] __lock_acquire+0x1054/0x1230 [<c0478d81>] ? sched_clock_cpu+0x121/0x180 [<c048a1ed>] lock_acquire+0x8d/0x110 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb358>] __mutex_lock_common+0x58/0x470 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<c08bb84a>] mutex_lock_nested+0x3a/0x50 [<facfa598>] ? show_statistics+0x48/0x100 [iwlagn] [<facfa598>] show_statistics+0x48/0x100 [iwlagn] [<c0580cf9>] ? sysfs_get_active+0x69/0xb0 [<facfa550>] ? show_statistics+0x0/0x100 [iwlagn] [<c070d219>] dev_attr_show+0x29/0x50 [<c057fecd>] sysfs_read_file+0xdd/0x190 [<c05ff314>] ? security_file_permission+0x14/0x20 [<c0528242>] ? rw_verify_area+0x62/0xd0 [<c052880f>] vfs_read+0x9f/0x190 [<c047745b>] ? up_read+0x1b/0x30 [<c057fdf0>] ? sysfs_read_file+0x0/0x190 [<c04af3b4>] ? audit_syscall_entry+0x1f4/0x220 [<c0528d22>] sys_read+0x42/0x70 [<c040ad9f>] sysenter_do_call+0x12/0x38 Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

2010-06-04rps: tcp: fix rps_sock_flow_table table updatesEric Dumazet
I believe a moderate SYN flood attack can corrupt RFS flow table (rps_sock_flow_table), making RPS/RFS much less effective. Even in a normal situation, server handling short lived sessions suffer from bad steering for the first data packet of a session, if another SYN packet is received for another session. We do following action in tcp_v4_rcv() : sock_rps_save_rxhash(sk, skb->rxhash); We should _not_ do this if sk is a LISTEN socket, as about each packet received on a LISTEN socket has a different rxhash than previous one. -> RPS_NO_CPU markers are spread all over rps_sock_flow_table. Also, it makes sense to protect sk->rxhash field changes with socket lock (We currently can change it even if user thread owns the lock and might use rxhash) This patch moves sock_rps_save_rxhash() to a sock locked section, and only for non LISTEN sockets.

2010-06-04net: check for refcount if pop a stacked dst_entrySteffen Klassert
xfrm triggers a warning if dst_pop() drops a refcount on a noref dst. This patch changes dst_pop() to skb_dst_pop(). skb_dst_pop() drops the refcnt only on a refcounted dst. Also we don't clone the child dst_entry, so it is not refcounted and we can use skb_dst_set_noref() in xfrm_output_one().

2010-06-04ath5k: retain promiscuous settingBob Copeland
Commit 56d1de0a21db28e41741cfa0a66e18bc8d920554, "ath5k: clean up filter flags setting" introduced a regression in monitor mode such that the promisc filter flag would get lost. Although we set the promisc flag when it changed, we did not preserve it across subsequent calls to configure_filter. This patch restores the original functionality.

2010-06-04ath5k: depend on CONFIG_PM_SLEEP for suspend/resume functionsTobias Doerffel
When building a kernel with CONFIG_PM=y but neither suspend nor hibernate support, the compiler complains about the static functions ath5k_pci_suspend() and ath5k_pci_resume() not being used: drivers/net/wireless/ath/ath5k/base.c:713:12: warning: ‘ath5k_pci_suspend’ defined but not used drivers/net/wireless/ath/ath5k/base.c:722:12: warning: ‘ath5k_pci_resume’ defined but not used Depending on CONFIG_PM_SLEEP rather than CONFIG_PM fixes the issue.

2010-06-04mac80211: process station blockack action frames from workJohannes Berg
Processing an association response could take a bit of time while we set up the hardware etc. During that time, the AP might already send a blockack request. If this happens very quickly on a fairly slow machine, we can end up processing the blockack request before the association processing has finished. Since the blockack processing cannot sleep right now, we also cannot make it wait in the driver. As a result, sometimes on slow machines the iwlagn driver gets totally confused, and no traffic can pass when the aggregation setup was done before the assoc setup completed. I'm working on a proper fix for this, which involves queuing all blockack category action frames from a work struct, and also allowing the ampdu_action driver callback to sleep, which will generally clean up the code and make things easier. However, this is a very involved and complex change. To fix the problem at hand in a way that can also be backported to stable, I've come up with this patch. Here, I simply process all aggregation action frames from the managed interface skb queue, which means their processing will be serialized with processing the association response, thereby fixing the problem.
