* net/cpsw: don't continue if we miss to allocate rx skbsSebastian Siewior2013-04-25
| | | | | | | | | | | | | | | | if during "ifconfig up" we run out of mem we continue regardless how many skbs we got. In worst case we have zero RX skbs and can't ever receive further packets since the RX skbs are never reallocated. If cpdma_chan_submit() fails we even leak the skb. This patch changes the behavior here: If we fail to allocate an skb during bring up we don't continue and report that error. Same goes for errors from cpdma_chan_submit(). While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can be used.

* net/davinci_cpdma: don't check for jiffies with interruptsSebastian Siewior2013-04-25
| | | | | | | | | | | | __cpdma_chan_process() holds the lock with interrupts off (and its caller as well), same goes for cpdma_ctlr_start(). With interrupts off, jiffies will not make any progress and if the wait condition never gets true we wait for ever. Tgis patch adds a a simple udelay and counting down attempt.

* bnx2x, bnx2fc: Use per port max exchange resourcesBhanu Prakash Gollapudi2013-04-25
| | | | | | | | | | | | | | | The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices, or when working in multi-function mode, this resource needs to be distributed between the various possible FCoE functions. This information needs to be calculated by bnx2x and propagated into bnx2fc via cnic. bnx2fc can then use this value to calculate corresponding xid resources instead of using global constants.

* openvswitch: Use parallel_ops genl.Pravin B Shelar2013-04-25
| | | | | | | | | | | | | OVS locking was recently changed to have private OVS lock which simplified overall locking. Therefore there is no need to have another global genl lock to protect OVS data structures. Following patch uses of parallel_ops genl family for OVS. This also allows more granual OVS locking using ovs_mutex for protecting OVS data structures, which gives more concurrencey. E.g multiple genl operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* genl: Allow concurrent genl callbacks.Pravin B Shelar2013-04-25
| | | | | | | | | | | | | | | | All genl callbacks are serialized by genl-mutex. This can become bottleneck in multi threaded case. Following patch adds an parameter to genl_family so that a particular family can get concurrent netlink callback without genl_lock held. New rw-sem is used to protect genl callback from genl family unregister. in case of parallel_ops genl-family read-lock is taken for callbacks and write lock is taken for register or unregistration for any family. In case of locked genl family semaphore and gel-mutex is locked for any openration. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* packet: account statistics only in tpacket_stats_uDaniel Borkmann2013-04-25
| | | | | | | | | | | | | | | | | | Currently, packet_sock has a struct tpacket_stats stats member for TPACKET_V1 and TPACKET_V2 statistic accounting, and with TPACKET_V3 ``union tpacket_stats_u stats_u'' was introduced, where however only statistics for TPACKET_V3 are held, and when copied to user space, TPACKET_V3 does some hackery and access also tpacket_stats' stats, although everything could have been done within the union itself. Unify accounting within the tpacket_stats_u union so that we can remove 8 bytes from packet_sock that are there unnecessary. Note that even if we switch to TPACKET_V3 and would use non mmap(2)ed option, this still works due to the union with same types + offsets, that are exposed to the user space.

| * packet: if hw/sw ts enabled in rx/tx ring, report which ts we gotDaniel Borkmann2013-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there is no way to find out which timestamp is reported in tpacket{,2,3}_hdr's tp_sec, tp_{n,u}sec members. It can be one of SOF_TIMESTAMPING_SYS_HARDWARE, SOF_TIMESTAMPING_RAW_HARDWARE, SOF_TIMESTAMPING_SOFTWARE, or a fallback variant late call from the PF_PACKET code in software. Therefore, report in the tp_status member of the ring buffer which timestamp has been reported for RX and TX path. This should not break anything for the following reasons: i) in RX ring path, the user needs to test for tp_status & TP_STATUS_USER, and later for other flags as well such as TP_STATUS_VLAN_VALID et al, so adding other flags will do no harm; ii) in TX ring path, time stamps with PACKET_TIMESTAMP socketoption are not available resp. had no effect except that the application setting this is buggy. Next to TP_STATUS_AVAILABLE, the user also should check for other flags such as TP_STATUS_WRONG_FORMAT to reclaim frames to the application. Thus, in case TX ts are turned off (default case), nothing happens to the application logic, and in case we want to use this new feature, we now can also check which of the ts source is reported in the status field as provided in the docs.
