2013-04-25e1000e: panic caused by Rx traffic arriving while interface going downBruce Allan1-2/+5
An "unable to handle kernel paging request" panic can occur when receiving traffic while the interface is going down. Wait for NAPI to be done with current context after disabling interrupts and then disable NAPI. See https://bugzilla.vyatta.com/show_bug.cgi?id=8837.

2013-04-25e1000e: fix numeric overflow in phc settime methodRichard Cochran1-2/+1
The PTP Hardware Clock settime function in the e1000e driver computes nanoseconds from a struct timespec. The code converts the seconds field .tv_sec by multiplying it with NSEC_PER_SEC. However, both operands are of type long, resulting in an unintended overflow. The patch fixes the issue by using the helper function from time.h.

2013-04-25openvswitch: Use parallel_ops genl.Pravin B Shelar1-4/+8
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>
2013-04-25genl: Allow concurrent genl callbacks.Pravin B Shelar2-38/+77
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>

2013-04-25packet: account statistics only in tpacket_stats_uDaniel Borkmann2-23/+17
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.

There's a 4 byte hole in packet_ring_buffer structure before prb_bdqc, that can be filled with 'pending' member, thus we can reduce the overall structure size from 224 bytes to 216 bytes. This also has the side-effect, that in struct packet_sock 2*4 byte holes after the embedded packet_ring_buffer members are removed, and overall, packet_sock can be reduced by 1 cacheline: Before: size: 1344, cachelines: 21, members: 24 After: size: 1280, cachelines: 20, members: 24 Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S.

2013-04-25packet: if hw/sw ts enabled in rx/tx ring, report which ts we gotDaniel Borkmann2-13/+28
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.

The remaining 8 patches are against igb and contain the following changes: * implement SERDES loopback configuration for i210 devices by unsetting sigdetect bit, so as to fix Ethtool loopback test failure * add support for the SMBI semaphore for I210/I211 devices * implement the new generic pci_vfs_assigned helper function (Alex's PCI helper function) * display warning when link speed is downgraded due to Smartspeed * ensure that VLAN hardware filtering remains enabled when the device is in promiscuous mode and VT mode simultaneously * cleanup dead code in igb * bump the driver version v2: updated the PCI patch to add SRIOV helper function to remove extern from the declaration of pci_vfs_assigned in pci.h and return 0 if SR-IOV is disabled which is inline with other PCI SR-IOV functions ==================== Signed-off-by: David S.

2013-04-24net/mlx4_en: Add a service taskAmir Vadai3-0/+47
Add a service task to run tasks that needed to be executed periodically. Currently the only task is a watchdog to catch NIC clock overflow, to make timestamping accurate. Will move the statistics task into this framework in a later patch. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-24net/mlx4_en: Support software timestampingAmir Vadai1-0/+2
Kernel software timestamping requires that the driver calls skb_tx_timestamp just before passing the skb to the HW MAC layer. This patch adds this call. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-24net/mlx4_en: Add HW timestamping (TS) supportAmir Vadai15-17/+375
The patch allows to enable/disable HW timestamping for incoming and/or outgoing packets. It adds and initializes all structs and callbacks needed by kernel TS API. To enable/disable HW timestamping appropriate ioctl should be used. Currently HWTSTAMP_FILTER_ALL/NONE and HWTSAMP_TX_ON/OFF only are supported. When enabling TS on receive flow - VLAN stripping will be disabled. Also were made all relevant changes in RX/TX flows to consider TS request and plant HW timestamps into relevant structures. mlx4_ib was fixed to compile with new mlx4_cq_alloc() signature.
