[ Upstream commit ecbce48f ] A null pointer would be passed to a call of the function "kfree" directly after a call of the function "kcalloc" failed at one place. Pass the data structure member "urb" instead for which memory was allocated before (so that this resource will be properly cleaned up). This issue was detected by using the Coccinelle software.

[ 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.

[ Upstream commit 7f43020e ] The previous fix listed bulk read of registers as root cause of accendential disabling of watchdog, since the watchdog counter register (WD_VAL) was zeroed. Fixes: 3769a375 rtc: pcf2127: bulk read only date and time registers. Tested with the same PCF2127 chip as Sean reveled root cause of WD_VAL register value zeroing was caused by reading CTRL2 register which is one of the watchdog feature control registers. So the solution is to not read the first two control registers (CTRL1 and CTRL2) in pcf2127_rtc_read_time as they are not needed anyway. Size of local buf variable is kept to allow easy usage of register defines to improve readability of code. Debug trace line was updated after CTRL1 and CTRL2 are no longer read from the chip. Also replaced magic numbers in buf access with register defines. Signed-off-by:

[ Upstream commit 623fd246 ] In case of sensor malfunction, stop streaming timeout takes much longer than expected. This is due to conversion of time to jiffies: milliseconds multiplied with HZ (ticks/second) gives out a value of jiffies with 10^3 greater. We need to also divide by 10^3 to obtain the right jiffies value. In other words FRAME_INTERVAL_MILLI_SEC must be in seconds in order to multiply by HZ and get the right jiffies value to add to the current jiffies for the timeout expire time.

[ Upstream commit 33b16568 ] The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both have giant structure on the stack, which makes each one use stack frames larger than 500 bytes. As clang decides one function into the other, we get a warning for exceeding the frame size limit on 32-bit architectures: drivers/net/ethernet/intel/i40e/i40e_common.c:1654:23: error: stack frame size of 1116 bytes in function 'i40e_set_fc' [-Werror,-Wframe-larger-than=] When building with gcc, the inlining does not happen, but i40e_set_fc() calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the kernel stack just as much. The parts that actually use large stacks don't overlap, so make sure each one is a separate function, and mark them as noinline_for_stack to prevent the compilers from combining them again.

[ 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 065af355 ] When generic-XDP was moved to a later processing step by commit 458bf2f2 ("net: core: support XDP generic on stacked devices.") a regression was introduced when using bpf_xdp_adjust_head. The issue is that after this commit the skb->network_header is now changed prior to calling generic XDP and not after. Thus, if the header is changed by XDP (via bpf_xdp_adjust_head), then skb->network_header also need to be updated again. Fix by calling skb_reset_network_header().

[ Upstream commit 33808413 ] Use devm_add_action_or_reset to call tsl2772_chip_off when the device is removed. This also fixes the issue that the chip is turned off before the device is unregistered. Not marked for stable as fairly hard to hit the bug and this is in the middle of a set making other cleanups to the driver. Hence will probably need explicit backporting. Signed-off-by:

[ Upstream commit 7c5b4205 ] In commit 365ad353 ("tipc: reduce risk of user starvation during link congestion") we allowed senders to add exactly one list of extra buffers to the link backlog queues during link congestion (aka "oversubscription"). However, the criteria for when to stop adding wakeup messages to the input queue when the overload abates is inaccurate, and may cause starvation problems during very high load. Currently, we stop adding wakeup messages after 10 total failed attempts where we find that there is no space left in the backlog queue for a certain importance level. The counter for this is accumulated across all levels, which may lead the algorithm to leave the loop prematurely, although there may still be plenty of space available at some levels. The result is sometimes that messages near the wakeup queue tail are not added to the input queue as they should be. We now introduce a more exact algorithm, where we keep adding wakeup messages to a level as long as the backlog queue has free slots for the corresponding level, and stop at the moment there are no more such slots or when there are no more wakeup messages to dequeue.

[ Upstream commit 72c8117a ] Each of the operations in ccp_run_cmd() needs several hundred bytes of kernel stack. Depending on the inlining, these may need separate stack slots that add up to more than the warning limit, as shown in this clang based build: drivers/crypto/ccp/ccp-ops.c:871:12: error: stack frame size of 1164 bytes in function 'ccp_run_aes_cmd' [-Werror,-Wframe-larger-than=] static int ccp_run_aes_cmd(struct ccp_cmd_queue *cmd_q, struct ccp_cmd *cmd) The problem may also happen when there is no warning, e.g. in the ccp_run_cmd()->ccp_run_aes_cmd()->ccp_run_aes_gcm_cmd() call chain with over 2000 bytes. Mark each individual function as 'noinline_for_stack' to prevent this from happening, and move the calls to the two special cases for aes into the top-level function. This will keep the actual combined stack usage to the mimimum: 828 bytes for ccp_run_aes_gcm_cmd() and at most 524 bytes for each of the other cases.

[ 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.
