* batman-adv: set the TAG flag for the vid passed to BLAAntonio Quartulli2013-09-17
| | | | | | | | | | | | | | | | | When receiving or sending a packet a packet on a VLAN, the vid has to be marked with the TAG flag in order to make any component in batman-adv understand that the packet is coming from a really tagged network. This fix the Bridge Loop Avoidance behaviour which was not able to send announces over VLAN interfaces.

* Merge branch 'sfc-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfcDavid S. Miller2013-09-16
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ben Hutchings says: ==================== Some bug fixes and future-proofing for the recently added SFC9120 support: 1. Minimal support for the 40G configuration. 2. Disable the incomplete PTP/hardware timestamping support. 3. Reset MAC stats properly after a firmware upgrade. 4. Re-check the datapath firmware capabilities after the controller is reset. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
| * sfc: Reinitialise and re-validate datapath caps after MC rebootBen Hutchings2013-09-11
| | | | | | | | | | | | | | | | | | After an MC reboot, the datapath may be running a different firmware variant and have different capabilities. It is critical that we know the current capabilities so that we can pass valid flags to MC_CMD_INIT_EVQ. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
| * sfc: Clean up validation of datapath capabilitiesBen Hutchings2013-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename efx_ef10_init_capabilities() to the more specific efx_ef10_init_datapath_caps(). Stop accepting short responses to MC_CMD_GET_CAPABILITIES; we don't need to support pre-production firmware. Move the check for RX prefix support from efx_ef10_probe() into efx_ef10_init_datapath_caps() and use consistent error messages for missing TSO support and missing RX prefix support.

| * sfc: Reset derived rx_bad_bytes statistic when EF10 MC is rebootedBen Hutchings2013-09-11
| | | | | | | | | | | | | | | | | | | | | | If the MC reboots then the stats it reports to us will have been reset. We need to reset ours to get efx_update_diff_stat() working properly.

| * sfc: Disable PTP on EF10 until we're ready to handle inline RX timestampsBen Hutchings2013-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Unlike Siena where timestamping is provided by a peripheral, EF10 delivers RX timestamps in the packet prefix. However the driver doesn't yet support this. We are also creating a PHC device for each EF10 function, even though the clock is really shared between all of them. Disable hardware PTP/timestamping support until it's complete. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

This does not include reporting of 40G media types, as those have not yet been assigned numbers in the MCDI protocol. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
* | net: sctp: rfc4443: do not report ICMP redirects to user spaceDaniel Borkmann2013-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adapt the same behaviour for SCTP as present in TCP for ICMP redirect messages. 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.

| | | | | | | | | | | | | | | | | | | | | | | | This is important patch for new devices that support unaligned addressing. That devices suffer from the backward-compatibility bug in DMA engine.

Jacob provides a ixgbe patch to fix the configure_rx patch to properly disable RSC hardware logic when a user disables it. Previously we only disabled RSC in the queue settings, but this does not fully disable hardware RSC logic which can lead to unexpected performance issues. Emil provides three fixes for ixgbe. First fixes the ethtool loopback test when DCB is enabled, where the frames may be modified on Tx (by adding VLAN tag) which will fail the check on receive. Then a fix for QSFP+ modules, limit the speed setting to advertise only one speed at a time since the QSFP+ modules do not support auto negotiation. Lastly, resolve an issue where the driver will display incorrect info for QSFP+ modules that were inserted after the driver has been loaded. David Ertman provides to fixes for e1000e, one removes a comparison to the boolean value true where evaluating the lvalue will produce the same result.

|/ / | | | | | | | | | | | | | | | | | | | | | | If rx_urb allocation fails in mcs_setup_urbs(), tx_urb leaks. If mcs_receive_start() fails in mcs_net_open(), the both urbs are not deallocated. The patch fixes the issues and by the way fixes label indentation. Found by Linux Driver Verification project (linuxtesting.org).

* | bridge: Clamp forward_delay when enabling STPHerbert Xu2013-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At some point limits were added to forward_delay. However, the limits are only enforced when STP is enabled. This created a scenario where you could have a value outside the allowed range while STP is disabled, which then stuck around even after STP is enabled. This patch fixes this by clamping the value when we enable STP. I had to move the locking around a bit to ensure that there is no window where someone could insert a value outside the range while we're in the middle of enabling STP.

* | resubmit bridge: fix message_age_timer calculationChris Healy2013-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the message_age_timer calculation to use the BPDU's max age as opposed to the local bridge's max age. This is in accordance with section 8.6.2.3.2 Step 2 of the 802.1D-1998 sprecification. With the current implementation, when running with very large bridge diameters, convergance will not always occur even if a root bridge is configured to have a longer max age. Tested successfully on bridge diameters of ~200. Signed-off-by: Chris Healy <cphealy@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
