During MSI-X setup the system might run out of vectors. If this happens the already assigned vectors for this NIC should be freed before trying the disable MSI-X. Failing to do so results in the following oops. kernel BUG at drivers/pci/msi.c:341!

Given a small change to igb_init_interrupt_scheme() the function fits igb_request_irq() for MSI/legacy interrupts initialization as well, instead of duplicating most of its code there. Also adding a missing igb_configure() to igb_request_irq() for MSI fallback to work properly. Signed-off-by:

The X540's internal thermal sensor should not be enabled for all devices, but only those devices which enable it in the NVM image. It is expected that actively cooled devices will have it enabled, but passively cooled devices might not want it enabled. This is due to passively cooled devices operating very near the thermal threshold, sometimes within the margin of error of the thermal sensor. Thus these devices may not be good candidates for using the thermal sensor. This patch uses the enabled bit in the FWSM register to check whether we should be enabling the thermal sensor, and only sets the THERMAL_SENSOR_CAPABLE flag for those devices which have it enabled.

If the initiator and target try to close the connection at about the same time, there is a race condition in the termination sequence for bnx2x. Fix the problem by waiting for the remote termination to complete before deleting the Connection ID. This will prevent the firmware assert. Update version to 2.5.15. Signed-off-by:

ipv6_sock_mc_close() is called for ipv6 sockets at close time, and most of them don't use multicast. Add a test to avoid contention on a shared spinlock. Same heuristic applies for ipv6_sock_ac_close(), to avoid contention on a shared rwlock. Signed-off-by:

unres_qlen_bytes and unres_qlen are int type. But multiple relation(unres_qlen_bytes = unres_qlen * SKB_TRUESIZE(ETH_FRAME_LEN)) will cause type overflow when seting unres_qlen. e.g. $ echo 1027506 > /proc/sys/net/ipv4/neigh/eth1/unres_qlen $ cat /proc/sys/net/ipv4/neigh/eth1/unres_qlen 1182657265 $ cat /proc/sys/net/ipv4/neigh/eth1/unres_qlen_bytes -2147479756 The gutted value is not that we setting。 But user/administrator don't know this is caused by int type overflow. what's more, it is meaningless and even dangerous that unres_qlen_bytes is set with negative number. Because, for unresolved neighbour address, kernel will cache packets without limit in __neigh_event_send()(e.g. (u32)-1 = 2GB). Signed-off-by:

- convert remaining htonl/ntohl +__raw_read/__raw_writel to swab32 + readl/writel - add missing __iomem qualifier in myri10ge_open() - fix dubious: x & !y warning by switching from logical to bitwise not The swab32 conversion fixes a bug in myri10ge_led() where big-endian machines would write the wrong pattern. The only remaining warning (lock context imbalance) is due to the use of __netif_tx_trylock(), and cannot easily be fixed. Signed-off-by:

When a new nic is created in namespace ns1, the kernel sends a KOBJ_ADD uevent to ns1. When the nic is moved to ns2, we only send a KOBJ_MOVE to ns2, and nothing to ns1. This patch changes that behavior so that when moving a nic from ns1 to ns2, we send a KOBJ_REMOVED to ns1 and KOBJ_ADD to ns2. (The KOBJ_MOVE is still sent to ns2). The effects of this can be seen when starting and stopping containers in an upstart based host. Lxc will create a pair of veth nics, the kernel sends KOBJ_ADD, and upstart starts network-instance jobs for each. When one nic is moved to the container, because no KOBJ_REMOVED event is received, the network-instance job for that veth never goes away. This was reported at https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1065589 With this patch the networ-instance jobs properly go away. The other oddness solved here is that if a nic is passed into a running upstart-based container, without this patch no network-instance job is started in the container. But when the container creates a new nic itself (ip link add new type veth) then network-interface jobs are created. With this patch, behavior comes in line with a regular host. v2: also send KOBJ_ADD to new netns. There will then be a _MOVE event from the device_rename() call, but that should be innocuous.

/proc/net/ip[6]_mr_cache allows to get all mfc entries, even if they are put in the unresolved list (mfc[6]_unres_queue). But only the table RT_TABLE_DEFAULT is displayed. This patch adds the parsing of the unresolved list when the dump is made via rtnetlink, hence each table can be checked. In IPv6, we set rtm_type in ip6mr_fill_mroute(), because in case of unresolved mfc __ip6mr_fill_mroute() will not set it. In IPv4, it is already done. Signed-off-by:

These statistics can be checked only via /proc/net/ip_mr_cache or SIOCGETSGCNT[_IN6] and thus only for the table RT_TABLE_DEFAULT. Advertising them via rtnetlink allows to get statistics for all cache entries, whatever the table is. Signed-off-by:

Pablo Neira Ayuso says: ==================== * Remove limitation in the maximum number of supported sets in ipset. Now ipset automagically increments the number of slots in the array of sets by 64 new spare slots, from Jozsef Kadlecsik. * Partially remove the generic queue infrastructure now that ip_queue is gone. Its only client is nfnetlink_queue now, from Florian Westphal. * Add missing attribute policy checkings in ctnetlink, from Florian Westphal. * Automagically kill conntrack entries that use the wrong output interface for the masquerading case in case of routing changes, from Jozsef Kadlecsik. * Two patches two improve ct object traceability. Now ct objects are always placed in any of the existing lists. This allows us to dump the content of unconfirmed and dying conntracks via ctnetlink as a way to provide more instrumentation in case you suspect leaks, from myself. ==================== Signed-off-by: -

This patch adds the ptp_caps structure, ptp api implementation, reference clock read and register/unregister functions. All the basic clock operations as described in Documentation/ptp/ptp.txt are supported. Frequency adjustment is performed using hardware with a 24 bit accumulator and a programmable correction value. On each clk, the correction value gets added to the accumulator and when it overflows, the time counter is incremented/decremented and the accumulator reset. So conversion from ppb to correction value is ppb * (1 << 24) / 1000000000 [Re-organized to put the ptp_clock_info struct declaration in one patch, added ptp_clock_info.name, and added locking to tg3_ptp_adjtime() based on input from Richard Cochran.] Signed-off-by:
