The per ring counters are implemented in SW. Now moving to have the total counters as the sum of all rings. This way the numbers will always be consistent and we no longer depend on HW buffer size limitations for those counters that can be insufficient in some cases.

The recent NVRAM patches sanitized how the driver deals with NVRAM data, but they failed to bring the SEEPROM interfaces inline with the new strategy. This patch brings the SEEPROM interfaces up to date. This patch also reverts commit 0d489ffb ("tg3: fix big endian MAC address collection failure").

"mac80211: fix basic rates setting from association response" introduced a copy/paste error. Unfortunately, this not just leads to wrong data being passed to the driver but is remotely exploitable for some hardware or driver combinations.

Currently beacon loss detection triggers after a scan. A probe request is sent and a message like this is printed to the log: wlan0: beacon loss from AP 00:12:17:e7:98:de - sending probe request But in fact there is no beacon loss, the beacons are just not received because of the ongoing scan. Fix it by updating last_beacon after the scan has finished.

As the sk_sleep wait queue actually lives in tfile, which may be detached from the tun device, bad things will happen when we use sk_sleep after detaching. Since the tun device is the persistent data structure here (when requested by the user), it makes much more sense to have the wait queue live there. There is no reason to have it in tfile at all since the only time we can wait is if we have a tun attached. In fact we already have a wait queue in tun_struct, so we might as well use it.

The commit c70f1829 ("tun: Fix races between tun_net_close and free_netdev") fixed a race where an asynchronous deletion of a tun device can hose a poll(2) on a tun fd attached to that device. However, this came at the cost of moving the tun wait queue into the tun file data structure. The problem with this is that it imposes restrictions on when and where the tun device can access the wait queue since the tun file may change at any time due to detaching and reattaching. In particular, now that we need to use the wait queue on the receive path it becomes difficult to properly synchronise this with the detachment of the tun device. This patch solves the original race in a different way. Since the race is only because the underlying memory gets freed, we can prevent it simply by ensuring that we don't do that until all tun descriptors ever attached to the device (even if they have since be detached because they may still be sitting in poll) have been closed. This is done by using reference counting the attached tun file descriptors. The refcount in tun->sk has been reappropriated for this purpose since it was already being used for that, albeit from the opposite angle. Note that we no longer zero tfile->tun since tun_get will return NULL anyway after the refcount on tfile hits zero. Instead it represents whether this device has ever been attached to a device.

Alex Sidorenko reported: "while experimenting with 'netem' we have found some strange behaviour. It seemed that ingress delay as measured by 'ping' command shows up on some hosts but not on others. After some investigation I have found that the problem is that skbuff->tstamp field value depends on whether there are any packet sniffers enabled. That is: - if any ptype_all handler is registered, the tstamp field is as expected - if there are no ptype_all handlers, the tstamp field does not show the delay" This patch prevents unnecessary update of tstamp in dev_queue_xmit_nit() on ingress path (with act_mirred) adding a check, so minimal overhead on the fast path, but only when sniffers etc. are active. Since netem at ingress seems to logically emulate a network before a host, tstamp is zeroed to trigger the update and pretend delays are from the outside.

The fatal error task can be scheduled while processing an offload packet in NAPI context when the connection handle is bogus. this can race with the ports being brought down and the cxgb3 workqueue being flushed. Stop napi processing before flushing the work queue. The ULP drivers (iSCSI, iWARP) might also schedule a task on keventd_wk while releasing a connection handle (cxgb3_offload.c::cxgb3_queue_tid_release()). The driver however does not flush any work on keventd_wq while being unloaded. This patch also fixes this. Also call cancel_delayed_work_sync in place of the the deprecated cancel_rearming_delayed_workqueue. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The Broadcom chips with 2.1 firmware handle the fallback case to a SCO link wrongly when setting up eSCO connections. < HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17 handle 11 voice setting 0x0060 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 > HCI Event: Connect Complete (0x03) plen 11 status 0x00 handle 1 bdaddr 00:1E:3A:xx:xx:xx type SCO encrypt 0x01 The Link Manager negotiates the fallback to SCO, but then sends out a Connect Complete event. This is wrong and the Link Manager should actually send a Synchronous Connection Complete event if the Setup Synchronous Connection has been used. Only the remote side is allowed to use Connect Complete to indicate the missing support for eSCO in the host stack. This patch adds a workaround for this which clearly should not be needed, but reality is that broken Broadcom devices are deployed.

Some Bluetooth chips (like the ones from Texas Instruments) don't do proper eSCO negotiations inside the Link Manager. They just return an error code and in case of the Kyocera ED-8800 headset it is just a random error. < HCI Command: Setup Synchronous Connection 0x01|0x0028) plen 17 handle 1 voice setting 0x0060 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 > HCI Event: Synchronous Connect Complete (0x2c) plen 17 status 0x1f handle 257 bdaddr 00:14:0A:xx:xx:xx type eSCO Error: Unspecified Error In these cases it is up to the host stack to fallback to a SCO setup and so retry with SCO parameters.

There is a missing call to rfcomm_dlc_clear_timer in the case that DEFER_SETUP is used and so the connection gets disconnected after the timeout even if it was successfully accepted previously. This patch adds a call to rfcomm_dlc_clear_timer to rfcomm_dlc_accept which will get called when the user accepts the connection by calling read() on the socket.

Instead, allocate extra IE memory if necessary. Normally, this isn't even necessary since there's enough space.

With this patch, nfnetlink returns -ENOMEM instead of -EPERM if we fail to create the nfnetlink netlink socket during the module loading. This is exactly what rtnetlink does in this case.
