[ Upstream commit 33da8e7c ] My recent to change to only use force_sig for a synchronous events wound up breaking signal reception cifs and drbd. I had overlooked the fact that by default kthreads start out with all signals set to SIG_IGN. So a change I thought was safe turned out to have made it impossible for those kernel thread to catch their signals. Reverting the work on force_sig is a bad idea because what the code was doing was very much a misuse of force_sig. As the way force_sig ultimately allowed the signal to happen was to change the signal handler to SIG_DFL. Which after the first signal will allow userspace to send signals to these kernel threads. At least for wake_ack_receiver in drbd that does not appear actively wrong. So correct this problem by adding allow_kernel_signal that will allow signals whose siginfo reports they were sent by the kernel through, but will not allow userspace generated signals, and update cifs and drbd to call allow_kernel_signal in an appropriate place so that their thread can receive this signal. Fixing things this way ensures that userspace won't be able to send signals and cause problems, that it is clear which signals the threads are expecting to receive, and it guarantees that nothing else in the system will be affected. This change was partly inspired by similar cifs and drbd patches that added allow_signal. Reported-by:

[ Upstream commit bc83f79b ] Generally, declaring a platform device as a static variable is a bad idea and can cause all kinds of problems, in particular with the DMA configuration and lifetime rules. A specific problem we hit here is from a bug in clang that warns about certain (otherwise valid) macros when used in static variables: drivers/misc/mic/card/mic_x100.c:285:27: warning: shift count >= width of type [-Wshift-count-overflow] static u64 mic_dma_mask = DMA_BIT_MASK(64); ^~~~~~~~~~~~~~~~ include/linux/dma-mapping.h:141:54: note: expanded from macro 'DMA_BIT_MASK' #define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1)) ^ ~~~ A slightly better way here is to create the platform device dynamically and set the dma mask in the probe function. This avoids the warning and some other problems, but is still not ideal because the device creation should really be separated from the driver, and the fact that the device has no parent means we have to force the dma mask rather than having it set up from the bus that the device is actually on.

[ Upstream commit 177b8007 ] When GSO frame has to be corrupted netem uses skb_gso_segment() to produce the list of frames, and re-enqueues the segments one by one. The backlog length has to be adjusted to account for new frames. The current calculation is incorrect, leading to wrong backlog lengths in the parent qdisc (both bytes and packets), and incorrect packet backlog count in netem itself. Parent backlog goes negative, netem's packet backlog counts all non-first segments twice (thus remaining non-zero even after qdisc is emptied). Move the variables used to count the adjustment into local scope to make 100% sure they aren't used at any stage in backports. Fixes: 6071bd1a ("netem: Segment GSO packets on enqueue") Signed-off-by:

[ Upstream commit d4ec9550 ] The assigment of FB_VMODE_NONINTERLACE to var->vmode should be a bit-wise or of FB_VMODE_NONINTERLACE instead of an assignment, otherwise the previous clearing of the FB_VMODE_MASK bits of var->vmode makes no sense and is redundant.

[ Upstream commit ae7352d3 ] Both IPv6 and 6lowpan are calling inet_frags_fini() too soon. inet_frags_fini() is dismantling a kmem_cache, that might be needed later when unregister_pernet_subsys() eventually has to remove frags queues from hash tables and free them. This fixes potential use-after-free, and is a prereq for the following patch. Fixes: d4ad4d22 ("inet: frags: use kmem_cache for inet_frag_queue") Signed-off-by:

[ Upstream commit 72abe3bc ] The locking in force_sig_info is not prepared to deal with a task that exits or execs (as sighand may change). The is not a locking problem in force_sig as force_sig is only built to handle synchronous exceptions. Further the function force_sig_info changes the signal state if the signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the delivery of the signal. The signal SIGKILL can not be ignored and can not be blocked and SIGNAL_UNKILLABLE won't prevent it from being delivered. So using force_sig rather than send_sig for SIGKILL is confusing and pointless. Because it won't impact the sending of the signal and and because using force_sig is wrong, replace force_sig with send_sig.

[ Upstream commit b0576f9e ] Clang warns: drivers/misc/sgi-xp/xpc_partition.c:73:14: warning: variable 'buf' is uninitialized when used within its own initialization [-Wuninitialized] void *buf = buf; ~~~ ^~~ 1 warning generated. Arnd's explanation during review: /* * Returns the physical address of the partition's reserved page through * an iterative number of calls. * * On first call, 'cookie' and 'len' should be set to 0, and 'addr' * set to the nasid of the partition whose reserved page's address is * being sought. * On subsequent calls, pass the values, that were passed back on the * previous call. * * While the return status equals SALRET_MORE_PASSES, keep calling * this function after first copying 'len' bytes starting at 'addr' * into 'buf'. Once the return status equals SALRET_OK, 'addr' will * be the physical address of the partition's reserved page. If the * return status equals neither of these, an error as occurred. */ static inline s64 sn_partition_reserved_page_pa(u64 buf, u64 *cookie, u64 *addr, u64 *len) so *len is set to zero on the first call and tells the bios how many bytes are accessible at 'buf', and it does get updated by the BIOS to tell us how many bytes it needs, and then we allocate that and try again.
