* dccp: Clean up slow-path input processingGerrit Renker2011-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch rearranges the order of statements of the slow-path input processing (i.e. any other state than OPEN), to resolve the following issues. 1. Dependencies: the order of statements now better matches RFC 4340, 8.5, i.e. step 7 is before step 9 (previously 9 was before 7), and parsing options in step 8 (which may consume resources) now comes after step 7. 2. Sequence number checks are omitted if in state LISTEN/REQUEST, due to the note underneath the table in RFC 4340, 7.5.3. As a result, CCID processing is now indeed confined to OPEN/PARTOPEN states, i.e. congestion control is performed only on the flow of data packets. This avoids pathological cases of doing congestion control on those messages which set up and terminate the connection. 3. Packets are now passed on to Ack Vector / CCID processing only after - step 7 (receive unexpected packets), - step 9 (receive Reset), - step 13 (receive CloseReq), - step 14 (receive Close) and only if the state is PARTOPEN. This simplifies CCID processing: - in LISTEN/CLOSED the CCIDs are non-existent; - in RESPOND/REQUEST the CCIDs have not yet been negotiated; - in CLOSEREQ and active-CLOSING the node has already closed this socket; - in passive-CLOSING the client is waiting for its Reset. In the last case, RFC 4340, 8.3 leaves it open to ignore further incoming data, which is the approach taken here. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>

| | | | | | | | | | | | | | | Unused symbols waste space. Commit 0e34e93177fb "(netpoll: add generic support for bridge and bonding devices)" added the symbol more than a year ago with the promise of "future use".

| | | | | | | | | | | | | | | | | | | | | | | | The IEEE 802.15.4 drivers were compiled by default with debugging, which caused them to be rather chatty and slow. This patch silences them.

* | rtnl: provide link dump consistency infoThomas Graf2011-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a change sequence counter to each net namespace which is bumped whenever a netdevice is added or removed from the list. If such a change occurred while a link dump took place, the dump will have the NLM_F_DUMP_INTR flag set in the first message which has been interrupted and in all subsequent messages of the same dump. Note that links may still be modified or renamed while a dump is taking place but we can guarantee for userspace to receive a complete list of links and not miss any. Testing: I have added 500 VLAN netdevices to make sure the dump is split over multiple messages. Then while continuously dumping links in one process I also continuously deleted and re-added a dummy netdevice in another process. Multiple dumps per seconds have had the NLM_F_DUMP_INTR flag set. I guess we can wait for Johannes patch to hit net-next via the wireless tree. I just wanted to give this some testing right away.

* | be2net: create/destroy rx-queues on interface open/closeSathya Perla2011-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some skews, the BE card sends pause frames (and not drop pkts) if there are no more posted buffers available for packet reception. This behaviour has a side effect: When an interface is disabled, buffers are no longer posted on the corresponding RX rings. All broadcast and multicast traffic being received on the port will quickly fill up the PMEM and cause pause push back. As the PMEM is shared by both the ports, all traffic being received on the other (enabled) port also gets stalled. The fix is to destroy RX rings when the interface is disabled. If there is no RX ring match in the RXF lookup, the packets are discarded and so don't hog the PMEM. The RXQ creation cmd must now use MCC instead of MBOX as they are are called post MCC queue creation. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

* | net: add external loopback test in ethtool self testAmit Kumar Salecha2011-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | External loopback test can be performed by application without any driver support on normal Ethernet cards. But on CNA devices, where multiple functions share same physical port. Here internal loopback test and external loopback test can be initiated by multiple functions at same time. To co exist all functions, firmware need to regulate what test can be run by which function. So before performing external loopback test, command need to send to firmware, which will quiescent other functions. User may not want to run external loopback test always. As special cable need to be connected for this test. So adding explicit flag in ethtool self test, which will specify interface to perform external loopback test.
