In commit 1ec047eb ("ipv6: introduce per-interface counter for dad-completed ipv6 addresses") I build the detection of the first operational link-local address much to complex. Additionally this code now has a race condition. Replace it with a much simpler variant, which just scans the address list when duplicate address detection completes, to check if this is the first valid link local address and send RS and MLD reports then.

Because the tcp-metrics is an RCU-list, it may be that two soft-interrupts are inside __tcp_get_metrics() for the same destination-IP at the same time. If this destination-IP is not yet part of the tcp-metrics, both soft-interrupts will end up in tcpm_new and create a new entry for this IP. So, we will have two tcp-metrics with the same destination-IP in the list. This patch checks twice __tcp_get_metrics(). First without holding the lock, then while holding the lock. The second one is there to confirm that the entry has not been added by another soft-irq while waiting for the spin-lock. Fixes: 51c5d0c4 (tcp: Maintain dynamic metrics in local cache.)

commit ae4b46e9 "net: rds: use this_cpu_* per-cpu helper" broke per-cpu handling for rds. chpfirst is the result of __this_cpu_read(), so it is an absolute pointer and not __percpu. Therefore, __this_cpu_write() should not operate on chpfirst, but rather on cache->percpu->first, just like __this_cpu_read() did before.

Commit 7509963c (e1000e: Fix a compile flag mis-match for suspend/resume) moved suspend and resume hooks to be available when CONFIG_PM is set. However, it can be set even if CONFIG_PM_SLEEP is not set causing following warnings to be emitted: drivers/net/ethernet/intel/e1000e/netdev.c:6178:12: warning: ‘e1000_suspend’ defined but not used [-Wunused-function] drivers/net/ethernet/intel/e1000e/netdev.c:6185:12: warning: ‘e1000_resume’ defined but not used [-Wunused-function] To fix this make the hooks to be available only when CONFIG_PM_SLEEP is set and remove CONFIG_PM wrapping from driver ops because this is already handled by SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS().

The bnx2x driver in its pci shutdown() callback releases its pci bars (in the same manner it does during its pci remove() callback). During a system reboot while VFs are enabled, its possible for the VF's remove to be called (as a result of pci_disable_sriov()) after its shutdown callback has already finished running; This will cause a paging request fault as the VF tries to access the pci bar which it has previously released, crashing the system. This patch further differentiates the shutdown and remove callbacks, preventing the pci release procedures from being called during shutdown.

Bob Falken reported that after 4G packets, multicast forwarding stopped working. This was because of a rule reference counter overflow which freed the rule as soon as the overflow happend. This patch solves this by adding the FIB_LOOKUP_NOREF flag to fib_rules_lookup calls. This is safe even from non-rcu locked sections as in this case the flag only implies not taking a reference to the rule, which we don't need at all. Rules only hold references to the namespace, which are guaranteed to be available during the call of the non-rcu protected function reg_vif_xmit because of the interface reference which itself holds a reference to the net namespace.

Fix inet_diag_dump_icsk() to reflect the fact that both TCP_TIME_WAIT and TCP_FIN_WAIT2 connections are represented by inet_timewait_sock (not just TIME_WAIT), and for such sockets the tw_substate field holds the real state, which can be either TCP_TIME_WAIT or TCP_FIN_WAIT2. This brings the inet_diag state-matching code in line with the field it uses to populate idiag_state. This is also analogous to the info exported in /proc/net/tcp, where get_tcp4_sock() exports sk->sk_state and get_timewait4_sock() exports tw->tw_substate. Before fixing this, (a) neither "ss -nemoi" nor "ss -nemoi state fin-wait-2" would return a socket in TCP_FIN_WAIT2; and (b) "ss -nemoi state time-wait" would also return sockets in state TCP_FIN_WAIT2. This is an old bug that predates 05dbc7b5 ("tcp/dccp: remove twchain").

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

In the past the IFA_PERMANENT flag indicated, that the valid and preferred lifetime where ignored. Since change fad8da3e ("ipv6 addrconf: fix preferred lifetime state-changing behavior while valid_lft is infinity") we honour at least the preferred lifetime on those addresses. As such the valid lifetime gets recalculated and updated to 0. If loopback address is added manually this problem does not occur. Also if NetworkManager manages IPv6, those addresses will get added via inet6_rtm_newaddr and thus will have a correct lifetime, too.

Starting with commit 80c33ddd "net: add might_sleep() call to napi_disable" bnx2x fails the might_sleep tests causing a stack trace to appear whenever the driver is unloaded, as local_bh_disable() is being called before napi_disable(). This changes the locking schematics related to CONFIG_NET_RX_BUSY_POLL, preventing the need for calling local_bh_disable() and thus eliminating the issue.

Close avn_cstates array with correct marker to avoid overflow in function intel_idle_cpu_init(). [rjw: The problem was introduced when commit 22e580d0 was merged on top of eba682a5 (intel_idle: shrink states tables).] Fixes: 22e580d0 (intel_idle: Fixed C6 state on Avoton/Rangeley processors) Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> Signed-off-by: Rafael J.

This reverts commit 9d046ccb. Commit 9d046ccb marks all state tables with __initdata, but the state table may be accessed when doing CPU online, which then causing system crash as below: [ 204.188841] BUG: unable to handle kernel paging request at ffffffff8227cce8 [ 204.196844] IP: [<ffffffff814aa1c0>] intel_idle_cpu_init+0x40/0x130 [ 204.203996] PGD 1e11067 PUD 1e12063 PMD 455859063 PTE 800000000227c062 [ 204.211638] Oops: 0000 [#1] SMP DEBUG_PAGEALLOC [ 204.216975] Modules linked in: x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd gpio_ich microcode joydev sb_edac edac_core ipmi_si lpc_ich ipmi_msghandler lp tpm_tis parport wmi mac_hid acpi_pad hid_generic ixgbe isci usbhid dca hid libsas ptp ahci libahci scsi_transport_sas megaraid_sas pps_core mdio [ 204.262815] CPU: 11 PID: 1489 Comm: bash Not tainted 3.13.0-rc7+ #48 [ 204.269993] Hardware name: Intel Corporation BRICKLAND/BRICKLAND, BIOS BRIVTIN1.86B.0047.L09.1312061514 12/06/2013 [ 204.281646] task: ffff8804303a24a0 ti: ffff880440fac000 task.ti: ffff880440fac000 [ 204.290311] RIP: 0010:[<ffffffff814aa1c0>] [<ffffffff814aa1c0>] intel_idle_cpu_init+0x40/0x130 [ 204.300184] RSP: 0018:ffff880440fadd28 EFLAGS: 00010286 [ 204.306192] RAX: ffffffff8227cca0 RBX: ffffe8fff1a03400 RCX: 0000000000000007 [ 204.314244] RDX: ffff88045f400000 RSI: 0000000000000009 RDI: 0000000000001120 [ 204.322296] RBP: ffff880440fadd38 R08: 0000000000000000 R09: 0000000000000001 [ 204.330411] R10: 0000000000000001 R11: 0000000000000000 R12: 000000000000001e [ 204.338482] R13: 00000000ffffffdb R14: 0000000000000001 R15: 0000000000000000 [ 204.346743] FS: 00007f64f7b0c740(0000) GS:ffff88045ce00000(0000) knlGS:0000000000000000 [ 204.355919] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 204.362449] CR2: ffffffff8227cce8 CR3: 0000000444ab0000 CR4: 00000000001407e0 [ 204.370520] Stack: [ 204.372853] 000000000000001e ffffffff81f10240 ffff880440fadd50 ffffffff814aa307 [ 204.381519] ffffffff81ea80e0 ffff880440fadda0 ffffffff8185a230 0000000000000000 [ 204.390196] 000000000000001e 0000000000000002 0000000000000002 0000000000000000 [ 204.398856] Call Trace: [ 204.401683] [<ffffffff814aa307>] cpu_hotplug_notify+0x57/0x70 [ 204.408638] [<ffffffff8185a230>] notifier_call_chain+0x100/0x150 [ 204.415553] [<ffffffff810a7dae>] __raw_notifier_call_chain+0xe/0x10 [ 204.422772] [<ffffffff81072163>] cpu_notify+0x23/0x50 [ 204.428616] [<ffffffff810723b2>] _cpu_up+0x132/0x1a0 [ 204.434361] [<ffffffff8107249d>] cpu_up+0x7d/0xa0 [ 204.439819] [<ffffffff81836c9c>] cpu_subsys_online+0x3c/0x90 [ 204.446345] [<ffffffff81554625>] device_online+0x45/0xa0 [ 204.452471] [<ffffffff815546ce>] online_store+0x4e/0x80 [ 204.458511] [<ffffffff815519a8>] dev_attr_store+0x18/0x30 [ 204.464744] [<ffffffff812a68f1>] sysfs_write_file+0x151/0x1c0 [ 204.471681] [<ffffffff81217ef1>] vfs_write+0xe1/0x160 [ 204.477524] [<ffffffff8121889c>] SyS_write+0x4c/0x90 [ 204.483270] [<ffffffff8185f2ed>] system_call_fastpath+0x1a/0x1f [ 204.490081] Code: 41 54 41 89 fc 8b 3d 48 25 85 01 53 48 8b 1d 30 25 85 01 48 03 1c c5 40 90 fb 81 48 8b 05 19 25 85 01 c7 43 0c 01 00 00 00 66 90 <48> 83 78 48 00 74 4f 41 83 c0 01 41 39 f0 7e 10 48 c7 c7 38 79 [ 204.515723] RIP [<ffffffff814aa1c0>] intel_idle_cpu_init+0x40/0x130 [ 204.522996] RSP <ffff880440fadd28> [ 204.526976] CR2: ffffffff8227cce8 [ 204.530766] ---[ end trace 336f56cc3d1cfc8c ]--- Fixes: 9d046ccb (intel_idle: mark states tables with __initdata tag) Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> Signed-off-by: Rafael J.
