git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "Lots of activity this round on performance improvements in target-core while benchmarking the prototype scsi-mq initiator code with vhost-scsi fabric ports, along with a number of iscsi/iser-target improvements and hardening fixes for exception path cases post v3.10 merge. The highlights include: - Make persistent reservations APTPL buffer allocated on-demand, and drop per t10_reservation buffer. (grover) - Make virtual LUN=0 a NULLIO device, and skip allocation of NULLIO device pages (grover) - Add transport_cmd_check_stop write_pending bit to avoid extra access of ->t_state_lock is WRITE I/O submission fast-path. (nab) - Drop unnecessary CMD_T_DEV_ACTIVE check from transport_lun_remove_cmd to avoid extra access of ->t_state_lock in release fast-path. (nab) - Avoid extra t_state_lock access in __target_execute_cmd fast-path (nab) - Drop unnecessary vhost-scsi wait_for_tasks=true usage + ->t_state_lock access in release fast-path. (nab) - Convert vhost-scsi to use modern se_cmd->cmd_kref TARGET_SCF_ACK_KREF usage (nab) - Add tracepoints for SCSI commands being processed (roland) - Refactoring of iscsi-target handling of ISCSI_OP_NOOP + ISCSI_OP_TEXT to be transport independent (nab) - Add iscsi-target SendTargets=$IQN support for in-band discovery (nab) - Add iser-target support for in-band discovery (nab + Or) - Add iscsi-target demo-mode TPG authentication context support (nab) - Fix isert_put_reject payload buffer post (nab) - Fix iscsit_add_reject* usage for iser (nab) - Fix iscsit_sequence_cmd reject handling for iser (nab) - Fix ISCSI_OP_SCSI_TMFUNC handling for iser (nab) - Fix session reset bug with RDMA_CM_EVENT_DISCONNECTED (nab) The last five iscsi/iser-target items are CC'ed to stable, as they do address issues present in v3.10 code.

2013-07-11watchdog: delete mpcore_wdt driverViresh Kumar5-473/+0
Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu interrupt (usually interrupt #30), and the GIC configuration should flag it as such. With this setup, request_irq() should fail, and the right API is request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq(). Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the right CPU. There are no users of this driver since a long time and it makes more sense to get rid of it as nobody is looking to fix it. In case somebody wakes up after this has been removed and needs it, please revert this driver and pick these updates (These were never pushed to mainline): http://comments.gmane.org/gmane.linux.ports.arm.kernel/245998 Signed-off-by: Viresh Kumar <[email protected]> Acked-by: Guenter Roeck <[email protected]> Signed-off-by: Wim Van Sebroeck <[email protected]>

2013-07-11gso: Update tunnel segmentation to support Tx checksum offloadAlexander Duyck3-9/+12
This change makes it so that the GRE and VXLAN tunnels can make use of Tx checksum offload support provided by some drivers via the hw_enc_features. Without this fix enabling GSO means sacrificing Tx checksum offload and this actually leads to a performance regression as shown below: Utilization Send Throughput local GSO 10^6bits/s % S state 6276.51 8.39 enabled 7123.52 8.42 disabled To resolve this it was necessary to address two items. First netif_skb_features needed to be updated so that it would correctly handle the Trans Ether Bridging protocol without impacting the need to check for Q-in-Q tagging. To do this it was necessary to update harmonize_features so that it used skb_network_protocol instead of just using the outer protocol. Second it was necessary to update the GRE and UDP tunnel segmentation offloads so that they would reset the encapsulation bit and inner header offsets after the offload was complete. As a result of this change I have seen the following results on a interface with Tx checksum enabled for encapsulated frames: Utilization Send Throughput local GSO 10^6bits/s % S state 7123.52 8.42 disabled 8321.75 5.43 enabled v2: Instead of replacing refrence to skb->protocol with skb_network_protocol just replace the protocol reference in harmonize_features to allow for double VLAN tag checks.

2013-07-11watchdog: core: don't try to stop device if not runningHector Palacios1-2/+4
A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS ioctl and flag WDIOS_DISABLECARD. If the device is closed after this operation, watchdog_release() is called and status bits checked for stopping it. Besides, if the device has not been unregistered a critical message "watchdog did not stop!" is printed, although the ioctl may have successfully stopped it already. Without the patch a user application sample code like this will successfully stop the watchdog, but the kernel will output the message "watchdog did not stop!": wd_fd = open("/dev/watchdog", O_RDWR); flags = WDIOS_DISABLECARD; ioctl(wd_fd, WDIOC_SETOPTIONS, &flags); close(wd_fd); Signed-off-by: Hector Palacios <[email protected]> Reviewed-by: Guenter Roeck <[email protected]> Signed-off-by: Wim Van Sebroeck <[email protected]>

2013-07-11ipv6: fix route selection if kernel is not compiled with CONFIG_IPV6_ROUTER_PREFHannes Frederic Sowa1-23/+40
This is a follow-up patch to 3630d40067a21d4dfbadc6002bb469ce26ac5d52 ("ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available"). Since the removal of rt->n in rt6_info we can end up with a dst == NULL in rt6_check_neigh. In case the kernel is not compiled with CONFIG_IPV6_ROUTER_PREF we should also select a route with unkown NUD state but we must not avoid doing round robin selection on routes with the same target. So introduce and pass down a boolean ``do_rr'' to indicate when we should update rt->rr_ptr. As soon as no route is valid we do backtracking and do a lookup on a higher level in the fib trie. v2: a) Improved rt6_check_neigh logic (no need to create neighbour there) and documented return values. v3: a) Introduce enum rt6_nud_state to get rid of the magic numbers (thanks to David Miller). b) Update and shorten commit message a bit to actualy reflect the source.

2013-07-11vxlan: Fix kernel crash on rmmod.Pravin B Shelar1-1/+1
vxlan exit module unregisters vxlan net and then it unregisters rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links(). vxlan_dellink() deletes vxlan-dev from vxlan_list which has list-head in vxlan-net-struct but that is already gone due to net-unregister. That is how we are getting following crash. Following commit fixes the crash by fixing module exit path.
