Currently the Orlov inode allocator searches for free inodes for a directory only in flex block groups with at most inodes_per_group/16 more directory inodes than average per flex block group. However with growing size of flex block group this becomes unnecessarily strict. Scale allowed difference from average directory count per flex block group with flex block group size as we do with other metrics.

From locking dependency perspective, sync version of cancel request should behave as if flush request, for it waits for completion of work if that work has already started execution. ---------- #include #include static DEFINE_MUTEX(mutex); static void work_fn(struct work_struct *work) { schedule_timeout_uninterruptible(HZ / 5); mutex_lock(&mutex); mutex_unlock(&mutex); } static DECLARE_WORK(work, work_fn); static int __init test_init(void) { schedule_work(&work); schedule_timeout_uninterruptible(HZ / 10); mutex_lock(&mutex); cancel_work_sync(&work); mutex_unlock(&mutex); return -EINVAL; } module_init(test_init); MODULE_LICENSE("GPL"); ---------- The check this patch restores was added by commit 0976dfc1d0cd80a4 ("workqueue: Catch more locking problems with flush_work()"). Then, lockdep's crossrelease feature was added by commit b09be676e0ff25bd ("locking/lockdep: Implement the 'crossrelease' feature"). As a result, this check was once removed by commit fd1a5b04dfb899f8 ("workqueue: Remove now redundant lock acquisitions wrt. workqueue flushes"). But lockdep's crossrelease feature was removed by commit e966eaeeb623f099 ("locking/lockdep: Remove the cross-release locking checks"). At this point, this check should have been restored. Then, commit d6e89786bed977f3 ("workqueue: skip lockdep wq dependency in cancel_work_sync()") introduced a boolean flag in order to distinguish flush_work() and cancel_work_sync(), for checking "struct workqueue_struct" dependency when called from cancel_work_sync() was causing false positives. Then, commit 87915adc3f0acdf0 ("workqueue: re-add lockdep dependencies for flushing") tried to restore "struct work_struct" dependency check, but by error checked this boolean flag. Like an example shown above indicates, "struct work_struct" dependency needs to be checked for both flush_work() and cancel_work_sync().

Note: "Cannot request framebuffer" is not a fatal error in hyperv_setup_gen1() as the code assumes there's some other framebuffer device there but we actually have some other PCI device (mlx4 in this case) config space there! The problem appears to be that vmbus_allocate_mmio() can use dedicated framebuffer region to serve any MMIO request from any device. The semantics one might assume of a parameter named "fb_overlap_ok" aren't implemented because !fb_overlap_ok essentially has no effect. The existing semantics are really "prefer_fb_overlap". This patch implements the expected and needed semantics, which is to not allocate from the frame buffer space when !fb_overlap_ok. Note, Gen2 VMs are usually unaffected by the issue because framebuffer region is already taken by EFI fb (in case kernel supports it) but Gen1 VMs may have this region unclaimed by the time Hyper-V PCI pass-through driver tries allocating MMIO space if Hyper-V DRM/FB drivers load after it. Devices can be brought up in any sequence so let's resolve the issue by always ignoring 'fb_mmio' region for non-FB requests, even if the region is unclaimed.

Instead of allocating a new dma-capable skb to be used for the next packet, this path allocates a skb and copies the data into it (reusing the existing sbk for the next packet). There are two bytes of junk data at the beginning of every packet. I believe these are inserted in order to allow aligned DMA and IP headers. We skip over them using skb_reserve. Before copying over the data, we must use a barrier to ensure we see the whole packet. The current code only synchronizes len bytes, starting from the beginning of the packet, including the junk bytes. However, this leaves off the final two bytes in the packet. Synchronize the whole packet. To reproduce this problem, ping a HME with a payload size between 17 and 214 $ ping -s 17 which will complain rather loudly about the data mismatch. Small packets (below 60 bytes on the wire) do not have this issue. I suspect this is related to the padding added to increase the minimum packet size.

So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which use "skb->head + skb->mac_header", out-of-bound access occurs. This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2() and reset mac header in multicast to solve this out-of-bound bug.

So dataoff should be assigned matchoff, not incremented by it. This issue can be seen in the scenario when there are multiple Contact headers and the first one is using a hostname and other headers use IP addresses. In this case, ct_sip_walk_headers will work as follows: The first ct_sip_get_header call to will find the first Contact header but will return -1 as the header uses a hostname. But matchoff will be changed to the offset of this header. After that, dataoff should be set to matchoff, so that the next ct_sip_get_header call find the next Contact header. But instead of assigning dataoff to matchoff, it is incremented by it, which is not correct, as matchoff is an absolute value of the offset. So on the next call to the ct_sip_get_header, dataoff will be incorrect, and the next Contact header may not be found at all.

We currently check the MokSBState variable to decide whether we should treat UEFI secure boot as being disabled, even if the firmware thinks otherwise. This is used by shim to indicate that it is not checking signatures on boot images. In the kernel, we use this to relax lockdown policies. However, in cases where shim is not even being used, we don't want this variable to interfere with lockdown, given that the variable may be non-volatile and therefore persist across a reboot. This means setting it once will persistently disable lockdown checks on a given system. So switch to the mirrored version of this variable, called MokSBStateRT, which is supposed to be volatile, and this is something we can check.
