| | | | | | | | | | | | | | | | | | RTR frames do have a valid data length code on CAN. The driver for SJA1000 did not handle that situation properly.

Follows my analysis: - 'ifconfig eth0 up' brings eth0 out of suspend, and usbnet_resume is called to schedule dev->bh, then rx urbs are submited to prepare for recieving data; - some usbnet devices will produce garbage rx packets flood if info->reset is not called in usbnet_open. - so there is no enough chances for usbnet_bh to handle and release recieved skb buffers since many rx interrupts consumes cpu, so out of memory for atomic allocation in rx_submit happened. This patch fixes the issue by simply not allowing schedule of usbnet_bh until device is opened.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

As a consequence, grabbing NIC access will fail and cause excessive messages and hangs.

| | * | | mwl8k: Reducing extra_tx_headroom for tx optimization in AP modeYogesh Ashok Powar2011-04-291-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tx_headroom required for mwl8k driver is 32 bytes and it can use the space for 802.11 header received from mac80211. mwl8k considers the smallest 802.11 frame (CTS2self of 10 bytes) that can be received from mac80211 to compute the extra_tx_headroom as 22 (32 - 10) bytes. When the wireless interface is part of bridge, this extra_tx_headroom requirement results in a memcpy in mac80211 (in function pskb_expand_head) for all the data frames needing L2 forwarding/bridging, when NET_SKB_PAD is defined as 32. This patch reduces the extra_tx_headroom by 8 bytes so that memcpy of data frames in mac80211 is avoided in this case. The resize will be required in driver for frames with 802.11 header size of less than 18 bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check status bits with mutex taken, because when we wait for mutex unlock, status can change. Patch should also make remaining sync commands be send with priv->mutex taken. That will prevent execute these commands when we are currently reset firmware, what could possibly cause troubles.

Serialization will also fix possible race conditions, because q->read_ptr, q->write_ptr are modified/used in parallel. Do not change callback, I did (and fixed) that mistake in iwlagn.
