Because there is a possibility that skb is kfree_skb()ed and zero cleared after ndo_start_xmit, we should not see the contents of skb like skb->len and skb->dev->name after ndo_start_xmit. But trace_net_dev_xmit does that and causes panic by NULL pointer dereference. This patch fixes trace_net_dev_xmit not to see the contents of skb directly. If you want to reproduce this panic, 1. Get tracepoint of net_dev_xmit on 2. Create 2 guests on KVM 2. Make 2 guests use virtio_net 4. Execute netperf from one to another for a long time as a network burden 5. host will panic(It takes about 30 minutes) Signed-off-by: NKoki Sanagi <sanagi.koki@jp.fujitsu.com> Signed-off-by: NDavid S.

The failed_get label is used after the call to clk_get has succeeded, so it should be moved up above the call to clk_put. The failed_req labels doesn't do anything different than failed_get, so delete it. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2; statement S; @@ e1 = clk_get@p1(...); ... when != e1 = e2 when != clk_put(e1) when any if (...) { ... when != clk_put(e1) when != if (...) { ... clk_put(e1) ... } * return@p3 ...; } else S // </smpl> Signed-off-by: NJulia Lawall <julia@diku.dk> Signed-off-by: NDavid S.

Currently the DM9000 driver requests the primary interrupt before it resets the chip and puts it into a known good state. This means that if the chip is asserting interrupt for some reason we can end up with a screaming IRQ that the interrupt handler is unable to deal with. Avoid this by only requesting the interrupt after we've reset the chip so we know what state it's in. This started manifesting itself on one of my boards in the past month or so, I suspect as a result of some core infrastructure changes removing some form of mitigation against bad behaviour here, even when things boot it seems that the new code brings the interface up more quickly.

The current code takes an unaligned pointer and does htonl() on it to make it big-endian, then does a memcpy(). The problem is that the compiler decides that since the pointer is to a __be32, it is legal to optimize the copy into a processor word store. However, on an architecture that does not handled unaligned writes in kernel space, this produces an unaligned exception fault. The solution is to track the pointer as a "char *" (which removes a bunch of unpleasant casts in any case), and then just use put_unaligned_be32() to write the value to memory.

Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the call and changes requested pipe to interrupt type (see usb_bulk_msg). However with usb_interrupt_msg() on bulk endpoint does not correct the pipe type to bulk, but instead URB is submitted with interrupt type pipe. So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw from working with OHCI. Fix this by detecting endpoint type and using correct endpoint/pipe types for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right URB type on 'EP 4 OUT'.

Fix kernel oops when trying to use passive scheduled scans. The reason was that in passive scans there are no SSIDs, so there was a NULL pointer dereference. To solve the problem, we now check the number of SSIDs provided in the sched_scan request and only access the list if there's one or more (ie. passive scan is not forced). We also force all the channels to be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally before the checks in the wl1271_scan_get_sched_scan_channels() function.

Use a different value for DFS dwell time when performing a scheduled scan. Previously we were using the same value as for normal passive scans.

DFS channels were never getting included in the scheduled scans, because they always contain the passive flag as well and the call was asking for DFS and active channels.

Before this patch, the command sequence number is being set before lbs_queue_cmd() adds the command to the queue. However, lbs_queue_cmd() sometimes forces commands to queue-jump (e.g. CMD_802_11_WAKEUP_CONFIRM). It currently does this without considering that sequence numbers might need adjusting to keep things running in order. Fix this by setting the sequence number at a later stage, just before we're actually submitting the command to the hardware. Also fixes a possible race where seqnum was being modified outside of the driver lock. Signed-off-by: NDaniel Drake <dsd@laptop.org> Acked-by: NDan Williams <dcbw@redhat.com> Signed-off-by: NJohn W.

Several crashes in cleanup_once() were reported in recent kernels. Commit d6cc1d64 (inetpeer: various changes) added a race in unlink_from_unused(). One way to avoid taking unused_peers.lock before doing the list_empty() test is to catch 0->1 refcnt transitions, using full barrier atomic operations variants (atomic_cmpxchg() and atomic_inc_return()) instead of previous atomic_inc() and atomic_add_unless() variants. We then call unlink_from_unused() only for the owner of the 0->1 transition. Add a new atomic_add_unless_return() static helper With help from Arun Sharma.
