The following scenario was encountered during testing of logical partition mobility on pseries partitions with bonded ibmvnic adapters in LACP mode. 1. Driver receives a signal that the device has been swapped, and it needs to reset to initialize the new device. 2. Driver reports loss of carrier and begins initialization. 3. Bonding driver receives NETDEV_CHANGE notifier and checks the slave's current speed and duplex settings. Because these are unknown at the time, the bond sets its link state to BOND_LINK_FAIL and handles the speed update, clearing AD_PORT_LACP_ENABLE. 4. Driver finishes recovery and reports that the carrier is on. 5. Bond receives a new notification and checks the speed again. The speeds are valid but miimon has not altered the link state yet. AD_PORT_LACP_ENABLE remains off. Because the slave's link state is still BOND_LINK_FAIL, no further port checks are made when it recovers. Though the slave devices are operational and have valid speed and duplex settings, the bond will not send LACPDU's. The simplest fix I can see is to force another speed check in bond_miimon_commit. This way the bond will update AD_PORT_LACP_ENABLE if needed when transitioning from BOND_LINK_FAIL to BOND_LINK_UP.

Pull preemption Kconfig fix from Thomas Gleixner: "The PREEMPT_RT stub config renamed PREEMPT to PREEMPT_LL and defined PREEMPT outside of the menu and made it selectable by both PREEMPT_LL and PREEMPT_RT.

[old]defconfig silently fixes it up and selects PREEMPT_NONE. Unbreak it by undoing the rename and adding a intermediate config symbol which is selected by both PREEMPT and PREEMPT_RT.

The merge of the CONFIG_PREEMPT_RT stub renamed CONFIG_PREEMPT to CONFIG_PREEMPT_LL which causes all defconfigs which have CONFIG_PREEMPT=y set to fall back to CONFIG_PREEMPT_NONE because CONFIG_PREEMPT depends on the preemption mode choice wich defaults to NONE. This also affects oldconfig builds. So rather than changing 114 defconfig files and being an annoyance to users, revert the rename and select a new config symbol PREEMPTION. That keeps everything working smoothly and the revelant ifdef's are going to be fixed up step by step.

There is a race between reading task->exit_state in pidfd_poll and writing it after do_notify_parent calls do_notify_pidfd. Expected sequence of events is: CPU 0 CPU 1 ------------------------------------------------ exit_notify do_notify_parent do_notify_pidfd tsk->exit_state = EXIT_DEAD pidfd_poll if (tsk->exit_state) However nothing prevents the following sequence: CPU 0 CPU 1 ------------------------------------------------ exit_notify do_notify_parent do_notify_pidfd pidfd_poll if (tsk->exit_state) tsk->exit_state = EXIT_DEAD This causes a polling task to wait forever, since poll blocks because exit_state is 0 and the waiting task is not notified again. A stress test continuously doing pidfd poll and process exits uncovered this bug. To fix it, we make sure that the task's exit_state is always set before calling do_notify_pidfd.

Some applications set tiny SO_SNDBUF values and expect TCP to just work. Recent patches to address CVE-2019-11478 broke them in case of losses, since retransmits might be prevented. We should allow these flows to make progress. This patch allows the first and last skb in retransmit queue to be split even if memory limits are hit. It also adds the some room due to the fact that tcp_sendmsg() and tcp_sendpage() might overshoot sk_wmem_queued by about one full TSO skb (64KB size). Note this allowance was already present in stable backports for kernels < 4.15 Note for < 4.15 backports : tcp_rtx_queue_tail() will probably look like : static inline struct sk_buff *tcp_rtx_queue_tail(const struct sock *sk) { struct sk_buff *skb = tcp_send_head(sk); return skb ? tcp_write_queue_prev(sk, skb) : tcp_write_queue_tail(sk); } Fixes: f070ef2a ("tcp: tcp_fragment() should apply sane memory limits") Signed-off-by: NEric Dumazet <edumazet@google.com> Reported-by: NAndrew Prout <aprout@ll.mit.edu> Tested-by: NAndrew Prout <aprout@ll.mit.edu> Tested-by: NJonathan Lemon <jonathan.lemon@gmail.com> Tested-by: NMichal Kubecek <mkubecek@suse.cz> Acked-by: NNeal Cardwell <ncardwell@google.com> Acked-by: NYuchung Cheng <ycheng@google.com> Acked-by: NChristoph Paasch <cpaasch@apple.com> Cc: Jonathan Looney <jtl@netflix.com> Signed-off-by: NDavid S.

The commit b3aa14f0 ("iommu: remove the mapping_error dma_map_ops method") incorrectly changed the checking from dma_ops_alloc_iova() in map_sg() causes a crash under memory pressure as dma_ops_alloc_iova() never return DMA_MAPPING_ERROR on failure but 0, so the error handling is all wrong. kernel BUG at drivers/iommu/iova.c:801!
