When the dlc is closed, rfcomm_dev_state_change() tries to release the port in the case it cannot get a reference to the tty. However this is racy and not even needed. Infact as Peter Hurley points out: 1. Only consider dlcs that are 'stolen' from a connected socket, ie. reused. Allocated dlcs cannot have been closed prior to port activate and so for these dlcs a tty reference will always be avail in rfcomm_dev_state_change() -- except for the conditions covered by #2b below. 2. If a tty was at some point previously created for this rfcomm, then either (a) the tty reference is still avail, so rfcomm_dev_state_change() will perform a hangup. So nothing to do, or, (b) the tty reference is no longer avail, and the tty_port will be destroyed by the last tty_port_put() in rfcomm_tty_cleanup. Again, no action required. 3. Prior to obtaining the dlc lock in rfcomm_dev_add(), rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to do here. 4. After releasing the dlc lock in rfcomm_dev_add(), rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a tty reference could not be obtained. Again, the best thing to do here is nothing. Any future attempted open() will block on rfcomm_dev_carrier_raised(). The unconnected device will exist until released by ioctl(RFCOMMRELEASEDEV). The patch removes the aforementioned code and uses the tty_port_tty_hangup() helper to hangup the tty.

This bug was introduced by commit 7a163bfb ("netconsole: avoid a crash with multiple sysfs writers"). In store_enabled() we have the following sequence: acquire nt->mutex then rtnl, but in the netconsole netdev notifier we have rtnl then nt->mutex effectively leading to a deadlock. The NULL pointer dereference that the above commit tries to fix is actually due to another bug in netpoll_cleanup(). This is fixed by dropping the mutex from the netdev notifier as it's already protected by rtnl. Signed-off-by: NNikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: NDavid S.

The patch 136d8f37 broke the skge driver. Note this part of the patch: + if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) { + dev_kfree_skb(nskb); + goto resubmit; + } + pci_unmap_single(skge->hw->pdev, dma_unmap_addr(e, mapaddr), dma_unmap_len(e, maplen), PCI_DMA_FROMDEVICE); skb = e->skb; prefetch(skb->data); - skge_rx_setup(skge, e, nskb, skge->rx_buf_size); The function skge_rx_setup modifies e->skb to point to the new skb. Thus, after this change, the new buffer, not the old, is returned to the networking stack. This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should be queued for 3.11-stable.

If local fragmentation is allowed, then ip_select_ident() and ip_select_ident_more() need to generate unique IDs to ensure correct defragmentation on the peer. For example, if IPsec (tunnel mode) has to encrypt large skbs that have local_df bit set, then all IP fragments that belonged to different ESP datagrams would have used the same identificator. If one of these IP fragments would get lost or reordered, then peer could possibly stitch together wrong IP fragments that did not belong to the same datagram. This would lead to a packet loss or data corruption. Signed-off-by: NAnsis Atteka <aatteka@nicira.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Without this patch, if a frontend cycles through states Closing and Closed (which Windows frontends need to do) then the netdev will be destroyed and requires re-invocation of hotplug scripts to restore state before the frontend can move to Connected. Thus when udev is not in use the backend gets stuck in InitWait. With this patch, the netdev is left alone whilst the backend is still online and is only de-registered and freed just prior to destroying the vif (which is also nicely symmetrical with the netdev allocation and registration being done during probe) so no re-invocation of hotplug scripts is required.

Otherwise the system will burn even brighter and worse, leave the user wondering what's going on exactly. Since we already have a panic handler which will (try) to restore the entire fbdev console mode, we can just bail out. Inspired by a patch from Konstantin Khlebnikov. The callchain leading to this, cut&pasted from Konstantin's original patch: callstack: panic() bust_spinlocks(1) unblank_screen() vc->vc_sw->con_blank() fbcon_blank() fb_blank() info->fbops->fb_blank() drm_fb_helper_blank() drm_fb_helper_dpms() drm_modeset_lock_all() mutex_lock(&dev->mode_config.mutex) Note that the entire locking in the fb helper around panic/sysrq and kdbg is ... non-existant. So we have a decent change of blowing up everything. But since reworking this ties in with funny concepts like the fbdev notifier chain or the impressive things which happen around console_lock while oopsing, I'll leave that as an exercise for braver souls than me.

After a vmalloc failure in ttm_dma_tt_alloc_page_directory(), ttm_dma_tt_init() will call ttm_tt_destroy() to cleanup, and end up inside the driver's unpopulate() hook when populate() has never yet been called. On nouveau, the first issue to be hit because of this is that dma_address[] may be a NULL pointer. After working around this, ttm_pool_unpopulate() may potentially hit the same issue with the pages[] array. It seems to make more sense to avoid calling unpopulate on already unpopulated TTMs than to add checks to all the implementations.

We need to let the setup stage complete cleanly even when the HCI device is rfkilled. Otherwise the HCI device will stay in an undefined state and never get notified to user space through mgmt (even when it gets unblocked through rfkill). This patch makes sure that hci_dev_open() can be called in the HCI_SETUP stage, that blocking the device doesn't abort the setup stage, and that the device gets proper powered down as soon as the setup stage completes in case it was blocked meanwhile. The bug that this patch fixed can be very easily reproduced using e.g. the rfkill command line too. By running "rfkill block all" before inserting a Bluetooth dongle the resulting HCI device goes into a state where it is never announced over mgmt, not even when "rfkill unblock all" is run.

commit 104a43ed cnic: Use CHIP_NUM macros from bnx2x.h changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE is supported or not. There is another place in cnic that is still using the old method to determine if FCoE is supported or not. The 2 methods may not yield the same result after the network interface is brought down and up. This will cause the crash as cnic_bnx2x_service_kcq() will access the uninitialized cp->kcq2. The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which uses the bnx2x NO_FCOE() macro. As a follow-up, we can clean up the code to remove the old method as it is no longer needed.

commit b9871bcf bnx2x: VF RSS support - PF side changed the configuration of the doorbell HW and it broke iSCSI and FCoE. We fix this by making compatible changes to the doorbell address in bnx2i and bnx2fc. For the userspace driver, we need to pass a modified CID so that the existing userspace driver will calculate the correct doorbell address and continue to work.

This essentially reverts commit efb9ca08 (kernel.org) / 58020a106879a8b372068741c81f0015c9b0b96dbv [[MIPS] Change get_cycles to always return 0.] Most users of get_cycles() invoke it as a timing interface. That's why in modern kernels it was never very much missed for. /dev/random however uses get_cycles() in the how the jitter in the interrupt timing contains some useful entropy.
