2011-05-02smsc95xx: fix reset checkRabin Vincent
The reset loop check should check the MII_BMCR register value for BMCR_RESET rather than for MII_BMCR (the register address, which also happens to be zero). Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-05-02tg3: Fix failure to enable WoL by default when possibleRafael J. Wysocki
tg3 is supposed to enable WoL by default on adapters which support that, but it fails to do so unless the adapter's /sys/devices/.../power/wakeup file contains 'enabled' during the initialization of the adapter. Fix that by making tg3 use device_set_wakeup_enable() to enable wakeup automatically whenever WoL should be enabled by default. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: David S.

In the buggy seqpacket case we were allowing unconnected sockets to call recvmsg and try to receive the pseudo packet. That is always wrong and as of commit 7361c36c5 the pseudo packet had become enough different from a normal packet that the kernel started oopsing. Do for seqpacket_recv what was done for seqpacket_send in 2.5 and only allow it on connected seqpacket sockets. Cc: stable@kernel.org Tested-by: Dan Aloni <dan@aloni.org> Signed-off-by: Eric W.

Noting that this error occured on a serdes based device, we noted that there were a few ethtool operations (most notably self_test and set_phys_id) that have execution paths that lead into bnx2_setup_serdes_phy. This function is notable because it executes a mod_timer call, which starts the bp->timer running. Currently bnx2 is setup to assume that this timer only nees to be stopped when bnx2_close or bnx2_suspend is called. Since the above ethtool operations are not gated on the net device having been opened however, that assumption is incorrect, and can lead to the timer still running after the module has been removed, leading to the oops above (as well as other simmilar oopses). Fix the problem by ensuring that the timer is stopped when pci_device_unregister is called.

2011-04-24r8169: don't request firmware when there's no userspace.François Romieu
The firmware is cached during the first successfull call to open() and released once the network device is unregistered. The driver uses the cached firmware between open() and unregister_netdev(). So far the firmware is optional : a failure to load the firmware does not prevent open() to success. It is thus necessary to 1) unregister all 816x / 810[23] devices and 2) force a driver probe to issue a new firmware load.

2011-04-22netconsole: fix deadlock when removing net driver that netconsole is using (v2)Neil Horman
A deadlock was reported to me recently that occured when netconsole was being used in a virtual guest. If the virtio_net driver was removed while netconsole was setup to use an interface that was driven by that driver, the guest deadlocked. No backtrace was provided because netconsole was the only console configured, but it became clear pretty quickly what the problem was. In netconsole_netdev_event, if we get an unregister event, we call __netpoll_cleanup with the target_list_lock held and irqs disabled. __netpoll_cleanup can, if pending netpoll packets are waiting call cancel_delayed_work_sync, which is a sleeping path. the might_sleep call in that path gets triggered, causing a console warning to be issued. The netconsole write handler of course tries to take the target_list_lock again, which we already hold, causing deadlock. The fix is pretty striaghtforward. Simply drop the target_list_lock and re-enable irqs prior to calling __netpoll_cleanup, the re-acquire the lock, and restart the loop. Confirmed by myself to fix the problem reported.

2011-04-21powerpc: Fix multicast problem in fs_enet driverAndrea Galbusera
mac-fec.c was setting individual UDP address registers instead of multicast group address registers when joining a multicast group. This prevented from correctly receiving UDP multicast packets. According to datasheet, replaced hash_table_high and hash_table_low with grp_hash_table_high and grp_hash_table_low respectively. Also renamed hash_table_* with grp_hash_table_* in struct fec declaration for 8xx: these registers are used only for multicast there. Tested on a MPC5121 based board.

The slave member of struct aggregator does not necessarily point to a slave which is part of the aggregator. It points to the slave structure containing the aggregator structure, while completely different slaves (or no slaves at all) may be part of the aggregator. The agg_device_up() function wrongly uses agg->slave to find the state of the aggregator. Use agg->lag_ports->slave instead.
