* pidns: Use task_active_pid_ns where appropriateEric W. Biederman2012-11-191-1/+2
| | | | | | | | | | | | | | | | | The expressions tsk->nsproxy->pid_ns and task_active_pid_ns aka ns_of_pid(task_pid(tsk)) should have the same number of cache line misses with the practical difference that ns_of_pid(task_pid(tsk)) is released later in a processes life. Furthermore by using task_active_pid_ns it becomes trivial to write an unshare implementation for the the pid namespace. So I have used task_active_pid_ns everywhere I can. In fork since the pid has not yet been attached to the process I use ns_of_pid, to achieve the same effect. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>

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.

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

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.

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>

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.

"remained_buf_len" has to be large enough to hold the value from "mgmt_ie_buf_len". That variable is type u32, but it only holds small values so I have changed to both variables to int. Also I removed the bogus initialization from "mgmt_ie_buf_len" so that GCC can detect if it is used unitialized. I moved the declaration of "remained_buf_len" closer to where it is used so it's easier to read.
