Patch fixes problem by adding .reset_resume calback, hence we do not unbind usb device on resume. This callback can be the same as normal .resume callback, sice we do all needed initalization during interface start, which is performed on resume [ ieee80211_resume() -> ieee80211_reconfig() -> rt2x00mac_start() -> rt2x00lib_start ].

Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

However, when freeing the en resources, the tx-ring QPs are released both in mlx4_en_destroy_tx_ring (one at a time) and in mlx4_en_free_resources (as a block release).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The delayed work function int_in_work() may call usb_reset_device() and thus, indirectly, the driver's pre_reset method. Trying to cancel the work synchronously in that situation would deadlock. Fix by avoiding cancel_work_sync() in the pre_reset method. If the reset was NOT initiated by int_in_work() this might cause int_in_work() to run after the post_reset method, with urb_int_in already resubmitted, so handle that case gracefully.

| | * | tcp: Reject invalid ack_seq to Fast Open socketsJerry Chu2012-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A packet with an invalid ack_seq may cause a TCP Fast Open socket to switch to the unexpected TCP_CLOSING state, triggering a BUG_ON kernel panic. When a FIN packet with an invalid ack_seq# arrives at a socket in the TCP_FIN_WAIT1 state, rather than discarding the packet, the current code will accept the FIN, causing state transition to TCP_CLOSING. This may be a small deviation from RFC793, which seems to say that the packet should be dropped. Unfortunately I did not expect this case for Fast Open hence it will trigger a BUG_ON panic. It turns out there is really nothing bad about a TFO socket going into TCP_CLOSING state so I could just remove the BUG_ON statements. But after some thought I think it's better to treat this case like TCP_SYN_RECV and return a RST to the confused peer who caused the unacceptable ack_seq to be generated in the first place.

| | * | pch_gbe: don't reset MAC_RX on FIFO overflowVeaceslav Falico2012-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when FIFO_ERR happens, we stop the dma, wait for it to become idle and then reset the whole MAC_RX logic (and after that we must re-set multicast addresses and also re-enable MAC_RX when we're finally ready to accept new packets). This leads to CRC errors on high number of incoming packets and is not needed according to the datasheet. This patch fixes it by the following steps: 1) remove this reset in pch_gbe_stop_receive(), which causes some functions to not be used anywhere 2) remove already unused functions pch_gbe_wait_clr_bit_irq() and pch_gbe_mac_reset_rx() to correctly build 3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to pch_gbe_up() where it's only needed after we've removed the MAC_RX reset 4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx() to more precisely reflect what the functions are now doing. After these changes we already don't see the CRC errors and gain some increase in RX processing speed. Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we were in RX_FIFO_ERR state and entered pch_gbe_napi_poll(), we'll anyway clean some rx space and thus can continue to receive more packets. Currently, we re-set the RX_FIFO_ERR in situations when we've exhausted our budget for RX cleaning or cleaned some TX packets. Removing it gives us +20%-40% speed increase and a lot less of RX_FIFO_ERRors reported. Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

So IPsec + IP defrag/reassembly (using skb coalescing), or TCP coalescing could leak secpath objects. Fix this bug by calling skb_release_head_state(skb) to properly release all possible references to linked objects.

Linville says: ==================== This is a batch of fixes intended for the 3.7 stream. Dan Carpenter brings a fix for a simple signedness bug that could prevent the proper termination of a loop. Felix Fietkau found a few more places that need to use ieee80211_free_txskb for properly releasing SKBs used by mac80211. Franky Lin offers a pair of brcmfmac fixes, both fixing simple state reporting errors. Hante Meuleman corrects an error reporting case that wasn't handling all types of errors properly. Johan Hedberg offers a fix for an issue discovered at the Bluetooth UnPlug Fest. Gustavo says "the patch fixes a failure to pair with devices that support the LE Secure Connections feature." Johannes Berg sends an iwlwifi fix to handle a message type that is too large for the normal command mechanism. He also provides a mac80211 fix to use HT20 channels when HT40 channels are not permitted. Jouni Malinen offers a mac80211 fix for a masking error that was incorrectly marking some frames. Piotr Haber provides a fix to make sure bcma devices are unregistered properly. Stanislav Yakovlev gives us a fix for a panic in the ipw2200 driver. Stanislaw Gruszka sends a pair of fixes: one prevents a mismatch on connection states between cfg80211 and mac80211; the other prevents some frame corruption related to handling encryption. ==================== Signed-off-by: David S.

Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.
