The driver is quite silent in case of probe failure, which makes it more difficult to diagnose problem from the kernel log. Add logging to all of the silent error paths ziirave_wdt_probe() to improve that. Signed-off-by:

Converting from ms to s requires dividing by 1000, not multiplying. So this is currently taking the smaller of new_timeout and 1.28e8, i.e. effectively new_timeout. The driver knows what it set max_hw_heartbeat_ms to, so use that value instead of doing a division at run-time. FWIW, this can easily be tested by booting into a busybox shell and doing "watchdog -t 5 -T 130 /dev/watchdog" - without this patch, the watchdog fires after 130&127 == 2 seconds.

The cpwd_compat_ioctl() contains a bogus mutex that dates back to a leftover BKL instance. Simplify the implementation by using the new compat_ptr_ioctl() helper function that will do the right thing for all calls here. Note that WIOCSTART/WIOCSTOP don't take any arguments, so the compat_ptr() conversion is not needed here, but it also doesn't hurt. Signed-off-by:

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. Reported-by:

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:Eric Dumazet <edumazet@google.com> Reported-by:

vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing using ip/ipv6 addresses, but don't make sure the header is available in skb->data[] (skb_headlen() is less then header size). Case: 1) igb driver from intel. 2) Packet size is greater then 255. 3) MPLS forwards to VRF device. So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound() functions. Signed-off-by:
