BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 7764d56b ] If we are able to load an existing inode cache off disk, we set the state of the cache to BTRFS_CACHE_FINISHED, but we don't wake up any one waiting for the cache to be available. This means that anyone waiting for the cache to be available, waiting on the condition that either its state is BTRFS_CACHE_FINISHED or its available free space is greather than zero, can hang forever. This could be observed running fstests with MOUNT_OPTIONS="-o inode_cache", in particular test case generic/161 triggered it very frequently for me, producing a trace like the following: [63795.739712] BTRFS info (device sdc): enabling inode map caching [63795.739714] BTRFS info (device sdc): disk space caching is enabled [63795.739716] BTRFS info (device sdc): has skinny extents [64036.653886] INFO: task btrfs-transacti:3917 blocked for more than 120 seconds.

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 82880222 ] We may want to use the device pointer in device_init_wakeup() with functions that expect the device to already be added with device_add(). For example, if we were to link the device initializing wakeup to something in sysfs such as a class for wakeups we'll run into an error. It looks like this code was written with the assumption that the device would be added before initializing wakeup due to the order of operations in power_supply_unregister(). Let's change the order of operations so we don't run into problems here.

Linus Torvalds authored
BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit ab9bb631 ] Commit dfe2a77f ("kfifo: fix kfifo_alloc() and kfifo_init()") made the kfifo code round the number of elements up. That was good for __kfifo_alloc(), but it's actually wrong for __kfifo_init(). The difference? __kfifo_alloc() will allocate the rounded-up number of elements, but __kfifo_init() uses an allocation done by the caller. We can't just say "use more elements than the caller allocated", and have to round down. The good news? All the normal cases will be using power-of-two arrays anyway, and most users of kfifo's don't use kfifo_init() at all, but one of the helper macros to declare a KFIFO that enforce the proper power-of-two behavior. But it looks like at least ibmvscsis might be affected. The bad news? Will Deacon refers to an old thread and points points out that the memory ordering in kfifo's is questionable. See https://lore.kernel.org/lkml/20181211034032.32338-1-yuleixzhang@tencent.com/ for more. Fixes: dfe2a77f ("kfifo: fix kfifo_alloc() and kfifo_init()") Reported-by:

BugLink: https://bugs.launchpad.net/bugs/1864773 [ Upstream commit 12051b31 ] The code in question is modifying a variable declared const through pointer manipulation. Such code is explicitly undefined behavior, and is the lone issue preventing malta_defconfig from booting when built with Clang: If an attempt is made to modify an object defined with a const-qualified type through use of an lvalue with non-const-qualified type, the behavior is undefined. LLVM is removing such assignments. A simple fix is to not declare variables const that you plan on modifying. Limiting the scope would be a better method of preventing unwanted writes to such a variable. Further, the code in question mentions "compiler bugs" without any links to bug reports, so it is difficult to know if the issue is resolved in GCC. The patch was authored in 2006, which would have been GCC 4.0.3 or 4.1.1. The minimal supported version of GCC in the Linux kernel is currently 4.6. For what its worth, there was UB before the commit in question, it just added a barrier and got lucky IRT codegen. I don't think there's any actual compiler bugs related, just runtime bugs due to UB.

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:

BugLink: https://bugs.launchpad.net/bugs/1864773 [ 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.
