* mwifiex: fix PCIe hs_cfg cancel cmd timeoutBing Zhao2013-09-261-3/+2
| | | | | | | | | | | | | | | For pcie8897, the hs_cfg cancel command (0xe5) times out when host comes out of suspend. This is caused by an incompleted host sleep handshake between driver and firmware. Like SDIO interface, PCIe also needs to go through firmware power save events to complete the handshake for host sleep configuration. Only USB interface doesn't require power save events for hs_cfg.

* rtlwifi: Align private space in rtl_priv structLarry Finger2013-09-261-1/+1
| | | | | | | | | | | | | The private array at the end of the rtl_priv struct is not aligned. On ARM architecture, this causes an alignment trap and is fixed by aligning that array with __align(sizeof(void *)). That should properly align that space according to the requirements of all architectures.

| | | | | | | | | | | | | The commit "ath9k: Optimize LNA check" tried to use the "rs_firstaggr" flag to optimize the LNA combining algorithm when processing subframes in an A-MPDU. This doesn't appear to work well in practice, so revert it and use the old method of relying on "rs_moreaggr".

| * Bluetooth: don't release the port in rfcomm_dev_state_change()Gianluca Anzolin2013-09-201-33/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Bluetooth: Fix rfkill functionality during the HCI setup stageJohan Hedberg2013-09-181-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

For such devices, the ACL alive for too long after the L2CAP disconnection. To avoid the ACL alive for too long after L2CAP disconnection, reset the ACL disconnect timeout back to HCI_DISCONN_TIMEOUT during L2CAP connect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While playing the peripheral role, the host gets a LE Long Term Key Request Event from the controller when a connection is established with a bonded device. The host then informs the LTK which should be used for the connection. Once the link is encrypted, the host gets an Encryption Change Event. Therefore we should set conn->pending_sec_level instead of conn-> sec_level in hci_le_ltk_request_evt. This way, conn->sec_level is properly updated in hci_encrypt_change_evt. Moreover, since we have a LTK associated to the device, we have at least BT_SECURITY_MEDIUM security level.

| * | netconsole: fix a deadlock with rtnl and netconsole's mutexNikolay Aleksandrov2013-09-191-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug was introduced by commit 7a163bfb7ce50895bbe67300ea610d31b9c09230 ("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: Nikolay Aleksandrov <nikolay@redhat.com> Signed-off-by: David S.

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: Ansis Atteka <aatteka@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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.

Adding back any prefix with a CIDR equal to or more specific than the one deleted will fix it. Steps to reproduce: ipset -N test hash:net ipset -A test 1.1.0.0/16 ipset -A test 2.2.2.0/24 ipset -T test 1.1.1.1 #1.1.1.1 IS in set ipset -D test 2.2.2.0/24 ipset -T test 1.1.1.1 #1.1.1.1 IS NOT in set This is due to the fact that the nets counter was unconditionally decremented prior to the iteration that shifts up the entries. Now, we first check if there is a proceeding entry and if not, decrement it and return. Otherwise, we proceed to iterate and then zero the last element, which, in most cases, will already be zero.

For IPv6, RFC4443, section 2.4. says: ... (e) An ICMPv6 error message MUST NOT be originated as a result of receiving the following: ... (e.2) An ICMPv6 redirect message [IPv6-DISC]. ... Therefore, do not report an error to user space, just invoke dst's redirect callback and leave, same for IPv4 as done in TCP as well. The implication w/o having this patch could be that the reception of such packets would generate a poll notification and in worst case it could even tear down the whole connection. Therefore, stop updating sk_err on redirects.
