[4.19-stable PATCH 0/2] dax: Don't access a freed inode

by Dan Williams

The original upstream fix, commit 55e56f06ed71 "dax: Don't access a freed inode", prompted an immediate cleanup request. Now that the cleanup has landed, commit d8a706414af4 "dax: Use non-exclusive wait in wait_entry_unlocked()", backport them both to -stable. --- Dan Williams (1): dax: Use non-exclusive wait in wait_entry_unlocked() Matthew Wilcox (1): dax: Don't access a freed inode fs/dax.c | 69 ++++++++++++++++++++++++++++---------------------------------- 1 file changed, 31 insertions(+), 38 deletions(-)

Hopefully can be included soon. The good news though is that with the improved test automation that Paulo/Aurelien/Ronnie have been doing, we have added more to the automated xfstests run before checkin and more importantly added various different mount configrations that are much broader (used to be only a very small set that ran) and so would have caught this (and also other regressions that had made it through over the past couple years). Now our next challenge is figuring out how to get automated tests for smb3 to run reasonably regularly against some of the stable kernels and also against the full backports of cifs.ko to earlier kernels etc. which some need to get the many security, performance and functional improvements over the past year. -- Thanks, Steve

[PATCH 03/16] crypto: ofb - fix handling partial blocks and make thread-safe

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Fix multiple bugs in the OFB implementation: 1. It stored the per-request state 'cnt' in the tfm context, which can be used by multiple threads concurrently (e.g. via AF_ALG). 2. It didn't support messages not a multiple of the block cipher size, despite being a stream cipher. 3. It didn't set cra_blocksize to 1 to indicate it is a stream cipher. To fix these, set the 'chunksize' property to the cipher block size to guarantee that when walking through the scatterlist, a partial block can only occur at the end. Then change the implementation to XOR a block at a time at first, then XOR the partial block at the end if needed. This is the same way CTR and CFB are implemented. As a bonus, this also improves performance in most cases over the current approach.

It will unlock the root node (and really every node) as it walks down the tree, only to re-lock it when it needs to do something. This is a problem because if we modify the tree we could cow a block in our path, which frees our reference to that block. Then once we get back to that shared block we'll free our reference to it again, and get ENOENT when trying to lookup our extent reference to that block in __btrfs_free_extent. This is ultimately happening because we have delayed items left to be processed for our deleted snapshot _after_ all of the inodes are closed for the snapshot. We only run the delayed inode item if we're deleting the inode, and even then we do not run the delayed insertions or delayed removals. These can be run at any point after our final inode does its last iput, which is what triggers the snapshot deletion. We can end up with the snapshot deletion happening and then have the delayed items run on that file system, resulting in the above problem. This problem has existed forever, however my patches made it much easier to hit as I wake up the cleaner much more often to deal with delayed iputs, which made us more likely to start the snapshot dropping work before the transaction commits, which is when the delayed items would generally be run. Before, generally speaking, we would run the delayed items, commit the transaction, and wakeup the cleaner thread to start deleting snapshots, which means we were less likely to hit this problem. You could still hit it if you had multiple snapshots to be deleted and ended up with lots of delayed items, but it was definitely harder. Fix for now by simply running all the delayed items before starting to drop the snapshot. We could make this smarter in the future by making the delayed items per-root, and then simply drop any delayed items for roots that we are going to delete. But for now just a quick and easy solution is the safest.

We follow the ancestors using the VFS' dget_parent() API. This means that if we create a new link for a file in a directory that is new (or in an any other new ancestor directory) and then fsync the file using an old hard link, we end up not logging the new ancestor, and on log replay that new hard link and ancestor do not exist. In some cases, involving renames, the file will not exist at all. Example: mkfs.btrfs -f /dev/sdb mount /dev/sdb /mnt mkdir /mnt/A touch /mnt/foo ln /mnt/foo /mnt/A/bar xfs_io -c fsync /mnt/foo <power failure> In this example after log replay only the hard link named 'foo' exists and directory A does not exist, which is unexpected. In other major linux filesystems, such as ext4, xfs and f2fs for example, both hard links exist and so does directory A after mounting again the filesystem. Checking if any new ancestors are new and need to be logged was added in 2009 by commit 12fcfd22fe5b ("Btrfs: tree logging unlink/rename fixes"), however only for the ancestors of the hard link (dentry) for which the fsync was issued, instead of checking for all ancestors for all of the inode's hard links. So fix this by tracking the id of the last transaction where a hard link was created for an inode and then on fsync fallback to a full transaction commit when an inode has more than one hard link and at least one new hard link was created in the current transaction. This is the simplest solution since this is not a common use case (adding frequently hard links for which there's an ancestor created in the current transaction and then fsync the file). In case it ever becomes a common use case, a solution that consists of iterating the fs/subvol btree for each hard link and check if any ancestor is new, could be implemented. This solves many unexpected scenarios reported by Jayashree Mohan and Vijay Chidambaram, and for which there is a new test case for fstests under review.

FAILED: patch "[PATCH] powerpc/tm: Set MSR[TS] just prior to recheckpoint" failed to apply to 4.4-stable tree

At restore_tm_sigcontexts(), after current task regs->msr[TS] bits are set, several __get_user() are called and then a recheckpoint is executed. This is a problem since a page fault (in kernel space) could happen when calling __get_user(). If it happens, the process MSR[TS] bits were already set, but recheckpoint was not executed, and SPRs are still invalid. The page fault can cause the current process to be de-scheduled, with MSR[TS] active and without tm_recheckpoint() being called. More importantly, without TEXASR[FS] bit set also. Since TEXASR might not have the FS bit set, and when the process is scheduled back, it will try to reclaim, which will be aborted because of the CPU is not in the suspended state, and, then, recheckpoint. This recheckpoint will restore thread->texasr into TEXASR SPR, which might be zero, hitting a BUG_ON(). kernel BUG at /build/linux-sf3Co9/linux-4.9.30/arch/powerpc/kernel/tm.S:434! cpu 0xb: Vector: 700 (Program Check) at [c00000041f1576d0] pc: c000000000054550: restore_gprs+0xb0/0x180 lr: 0000000000000000 sp: c00000041f157950 msr: 8000000100021033 current = 0xc00000041f143000 paca = 0xc00000000fb86300 softe: 0 irq_happened: 0x01 pid = 1021, comm = kworker/11:1 kernel BUG at /build/linux-sf3Co9/linux-4.9.30/arch/powerpc/kernel/tm.S:434!

With this patch, the MSR[TS] will only be set just before recheckpointing and setting TEXASR[FS] = 1, thus avoiding an interrupt with TM registers in invalid state. Other than that, if CONFIG_PREEMPT is set, there might be a preemption just after setting MSR[TS] and before tm_recheckpoint(), thus, this block must be atomic from a preemption perspective, thus, calling preempt_disable/enable() on this code. It is not possible to move tm_recheckpoint to happen earlier, because it is required to get the checkpointed registers from userspace, with __get_user(), thus, the only way to avoid this undesired behavior is delaying the MSR[TS] set. The 32-bits signal handler seems to be safe this current issue, but, it might be exposed to the preemption issue, thus, disabling preemption in this chunk of code.

The following diagram shows how this happens.

Fix this by correctly checking whether the current page belongs to the range being instantiated and if so adjsut the range parameters passed for cleaning up.

The reason this case is valid is due to find_lock_delalloc_range returning any available range after the passed delalloc_start and ignoring whether the page under writeback is within that range. In turn ordered extents (OE) are always created for the returned range from find_lock_delalloc_range. If, however, a failure occurs while OE are being created then the clean up code in btrfs_cleanup_ordered_extents will be called. Unfortunately the code in btrfs_cleanup_ordered_extents doesn't consider the case of such 'foreign' range being processed and instead it always assumes that the range OE are created for belongs to the page. This leads to the first page of such foregin range to not be cleaned up since it's deliberately missed and skipped by the current cleaning up code. Fix this by correctly checking whether the current page belongs to the range being instantiated and if so adjsut the range parameters passed for cleaning up. If it doesn't, then just clean the whole OE range directly.

FAILED: patch "[PATCH] ext4: avoid declaring fs inconsistent due to invalid file" failed to apply to 4.4-stable tree

This can be reproduced by creating a test file system via "mke2fs -t ext4 -O metadata_csum /tmp/foo.img 8M", mounting it, cd'ing into that directory, and then running the following program. #define _GNU_SOURCE #include <fcntl.h> struct handle { struct file_handle fh;

Since it's an old interface, changing would require changing many call sites. So instead we create our own ext4_sb_bread(), which also allows us to set the REQ_META flag. Also fixed a problem in the xattr code where a NULL return in a function could also mean that the xattr was not found, which could lead to the wrong error getting returned to userspace.

FAILED: patch "[PATCH] ext4: add ext4_sb_bread() to disambiguate ENOMEM cases" failed to apply to 4.9-stable tree

Since it's an old interface, changing would require changing many call sites. So instead we create our own ext4_sb_bread(), which also allows us to set the REQ_META flag. Also fixed a problem in the xattr code where a NULL return in a function could also mean that the xattr was not found, which could lead to the wrong error getting returned to userspace.

FAILED: patch "[PATCH] KVM: PPC: Book3S HV: Fix race between kvm_unmap_hva_range and" failed to apply to 4.19-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 234ff0b729ad882d20f7996591a964965647addf Mon Sep 17 00:00:00 2001 From: Paul Mackerras <paulus(a)ozlabs.org> Date: Fri, 16 Nov 2018 21:28:18 +1100 Subject: [PATCH] KVM: PPC: Book3S HV: Fix race between kvm_unmap_hva_range and MMU mode switch Testing has revealed an occasional crash which appears to be caused by a race between kvmppc_switch_mmu_to_hpt and kvm_unmap_hva_range_hv. The symptom is a NULL pointer dereference in __find_linux_pte() called from kvm_unmap_radix() with kvm->arch.pgtable == NULL. Looking at kvmppc_switch_mmu_to_hpt(), it does indeed clear kvm->arch.pgtable (via kvmppc_free_radix()) before setting kvm->arch.radix to NULL, and there is nothing to prevent kvm_unmap_hva_range_hv() or the other MMU callback functions from being called concurrently with kvmppc_switch_mmu_to_hpt() or kvmppc_switch_mmu_to_radix(). This patch therefore adds calls to spin_lock/unlock on the kvm->mmu_lock around the assignments to kvm->arch.radix, and makes sure that the partition-scoped radix tree or HPT is only freed after changing kvm->arch.radix. This also takes the kvm->mmu_lock in kvmppc_rmap_reset() to make sure that the clearing of each rmap array (one per memslot) doesn't happen concurrently with use of the array in the kvm_unmap_hva_range_hv() or the other MMU callbacks.

[v4.9, v4.14] qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device ID

by Bjørn Mork

Hello! Please apply commit 102cd9096356 ("qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device ID") to the v4.9 and v4.14 longterm branches. Note: There is no point in backporting it to earlier releases, as the affected devices need the "raw-ip" feature introduced in v4.5. Thanks, Bjørn

This fixes possible kernel oops when userspace tries to mmap an area on 1 page bigger than was allocated by vmalloc_user() call: the size check inside remap_vmalloc_range_partial() accounts non-existing guard page also, so check successfully passes but vmalloc_to_page() returns NULL (guard page does not physically exist). The following code pattern example should trigger an oops: static int oops_mmap(struct file *file, struct vm_area_struct *vma) { void *mem; mem = vmalloc_user(4096); BUG_ON(!mem); /* Do not care about mem leak */ return remap_vmalloc_range(vma, mem, 0); } And userspace simply mmaps size + PAGE_SIZE: mmap(NULL, 8192, PROT_WRITE|PROT_READ, MAP_PRIVATE, fd, 0); Possible candidates for oops which do not have any explicit size checks: *** drivers/media/usb/stkwebcam/stk-webcam.c: v4l_stk_mmap[789] ret = remap_vmalloc_range(vma, sbuf->buffer, 0); Or the following one: *** drivers/video/fbdev/core/fbmem.c static int fb_mmap(struct file *file, struct vm_area_struct * vma) ... res = fb->fb_mmap(info, vma); Where fb_mmap callback calls remap_vmalloc_range() directly without any explicit checks: *** drivers/video/fbdev/vfb.c static int vfb_mmap(struct fb_info *info, struct vm_area_struct *vma) { return remap_vmalloc_range(vma, (void *)info->fix.smem_start, vma->vm_pgoff); } Link: http://lkml.kernel.org/r/20190103145954.16942-2-rpenyaev@suse.de Signed-off-by: Roman Penyaev <rpenyaev(a)suse.de> Acked-by: Michal Hocko <mhocko(a)suse.com> Cc: Andrey Ryabinin <aryabinin(a)virtuozzo.com> Cc: Joe Perches <joe(a)perches.com> Cc: "Luis R.

Commit 5eed6f1dff87 ("fork,memcg: fix crash in free_thread_stack on memcg charge fail") fixes a crash caused due to failed memcg charge of the kernel stack. However the fix misses the cached_stacks case which this patch fixes. So, the same crash can happen if the memcg charge of a cached stack is failed.

[PATCH 04/16] crypto: pcbc - remove bogus memcpy()s with src == dest

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> The memcpy()s in the PCBC implementation use walk->iv as both the source and destination, which has undefined behavior. These memcpy()'s are actually unneeded, because walk->iv is already used to hold the previous plaintext block XOR'd with the previous ciphertext block. Thus, walk->iv is already updated to its final value. So remove the broken and unnecessary memcpy()s.

[PATCH v2] can: gw: ensure DLC boundaries after CAN frame modification

by Marc Kleine-Budde

From: Oliver Hartkopp <socketcan(a)hartkopp.net> Muyu Yu provided a POC where user root with CAP_NET_ADMIN can create a CAN frame modification rule that makes the data length code a higher value than the available CAN frame data size. In combination with a configured checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in skb_shared_info) can be rewritten which finally can cause a system crash. Michael Kubecek suggested to drop frames that have a DLC exceeding the available space after the modification process and provided a patch that can handle CAN FD frames too. Within this patch we also limit the length for the checksum calculations to the maximum of Classic CAN data length (8). CAN frames that are dropped by these additional checks are counted with the CGW_DELETED counter which indicates misconfigurations in can-gw rules. This fixes CVE-2019-3701.

[PATCH 1/3] arm64: compat: Avoid sending SIGILL for unallocated syscall numbers

by Will Deacon

The ARM Linux kernel handles the EABI syscall numbers as follows: 0 - NR_SYSCALLS-1 : Invoke syscall via syscall table NR_SYSCALLS - 0xeffff : -ENOSYS (to be allocated in future) 0xf0000 - 0xf07ff : Private syscall or -ENOSYS if not allocated > 0xf07ff : SIGILL Our compat code gets this wrong and ends up sending SIGILL in response to all syscalls greater than NR_SYSCALLS which have a value greater than 0x7ff in the bottom 16 bits. Fix this by defining the end of the ARM private syscall region and checking the syscall number against that directly. Update the comment while we're at it.

[PATCH] can: gw: ensure DLC boundaries after CAN frame modification

by Oliver Hartkopp

The CAN frame modification rules allow bitwise logical operations which can be also applied to the can_dlc field. Ensure the manipulation result to maintain the can_dlc boundaries so that the CAN drivers do not accidently write arbitrary content beyond the data registers in the CAN controllers I/O mem when processing can-gw manipulated outgoing frames. When passing these frames to user space this issue did not have any effect to the kernel or any leaked data as we always strictly copy sizeof(struct can_frame) bytes.

There is a mismatch between perf list and driver definition on rw_chg event. # perf list | grep chg hisi_sccl1_ddrc0/rnk_chg/ [Kernel PMU event] hisi_sccl1_ddrc0/rw_chg/ [Kernel PMU event] But the register offset of rw_chg event is not defined in the driver, meanwhile bnk_chg register offset is mis-defined, let's fixup it.

[PATCH v3 1/1] scsi: Synchronize request queue PM status only on successful resume

by stanley.chu＠mediatek.com

From: Stanley Chu <stanley.chu(a)mediatek.com> The commit 356fd2663cff ("scsi: Set request queue runtime PM status back to active on resume") fixed up the inconsistent RPM status between request queue and device. However changing request queue RPM status shall be done only on successful resume, otherwise status may be still inconsistent as below, Request queue: RPM_ACTIVE Device: RPM_SUSPENDED This ends up soft lockup because requests can be submitted to underlying devices but those devices and their required resource are not resumed. For example, After above inconsistent status happens, IO request can be submitted to UFS device driver but required resource (like clock) is not resumed yet thus lead to warning as below call stack, WARN_ON(hba->clk_gating.state != CLKS_ON); ufshcd_queuecommand scsi_dispatch_cmd scsi_request_fn __blk_run_queue cfq_insert_request __elv_add_request blk_flush_plug_list blk_finish_plug jbd2_journal_commit_transaction kjournald2 We may see all behind IO requests hang because of no response from storage host or device and then soft lockup happens in system.

[PATCH 02/16] crypto: cfb - remove bogus memcpy() with src == dest

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> The memcpy() in crypto_cfb_decrypt_inplace() uses walk->iv as both the source and destination, which has undefined behavior. It is unneeded because walk->iv is already used to hold the previous ciphertext block; thus, walk->iv is already updated to its final value. So, remove it. Also, note that in-place decryption is the only case where the previous ciphertext block is not directly available. Therefore, as a related cleanup I also updated crypto_cfb_encrypt_segment() to directly use the previous ciphertext block rather than save it into walk->iv. This makes it consistent with in-place encryption and out-of-place decryption; now only in-place decryption is different, because it has to be.

[PATCH 01/16] crypto: cfb - add missing 'chunksize' property

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Like some other block cipher mode implementations, the CFB implementation assumes that while walking through the scatterlist, a partial block does not occur until the end. But the walk is incorrectly being done with a blocksize of 1, as 'cra_blocksize' is set to 1 (since CFB is a stream cipher) but no 'chunksize' is set.

[PATCH] drm/amd/display: Fix unintialized max_bpc state values

by Alex Deucher

From: Nicholas Kazlauskas <nicholas.kazlauskas(a)amd.com> [Why] If the "max bpc" isn't explicitly set in the atomic state then it have a value of 0. This has the correct behavior of limiting a panel to 8bpc in the case where the panel supports 8bpc. In the case of eDP panels this isn't a true assumption - there are panels that can only do 6bpc. Banding occurs for these displays. [How] Initialize the max_bpc when the connector resets to 8bpc. Also carry over the value when the state is duplicated. Bugzilla: https://bugs.freedesktop.org/108825 Fixes: 307638884f72 ("drm/amd/display: Support amdgpu "max bpc" connector property") Backport of commit 49f1c44b581b08e3289127ffe58bd208c3166701 upstream.

The 4.9 version of arch_dup_mmap() does not contain the ldt_dup_context() line. We just need to add arch_dup_pkeys(), like so: void arch_dup_mmap(struct mm_struct *oldmm, struct mm_struct *mm) { + arch_dup_pkeys(oldmm, mm); paravirt_arch_dup_mmap(oldmm, mm); } Should be a pretty simple merge. We can basically ignore the ldt_dup_context() changes.

[PATCH v2] nvmet-rdma: fix null dereference under heavy load

by Raju Rangoju

Under heavy load if we don't have any pre-allocated rsps left, we dynamically allocate a rsp, but we are not actually allocating memory for nvme_completion (rsp->req.rsp). In such a case, accessing pointer fields (req->rsp->status) in nvmet_req_init() will result in crash. To fix this, allocate the memory for nvme_completion by calling nvmet_rdma_alloc_rsp() Fixes: 8407879c("nvmet-rdma:fix possible bogus dereference under heavy load") Cc: <stable(a)vger.kernel.org> Reviewed-by: Max Gurtovoy <maxg(a)mellanox.com> Signed-off-by: Raju Rangoju <rajur(a)chelsio.com> -- Changes from v1: - Moved integer to 'if' block - Used 'unlikely' in datapath flow condition --- drivers/nvme/target/rdma.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/drivers/nvme/target/rdma.c b/drivers/nvme/target/rdma.c index a8d23eb80192..8f9e6645fcf9 100644 --- a/drivers/nvme/target/rdma.c +++ b/drivers/nvme/target/rdma.c @@ -139,6 +139,10 @@ static void nvmet_rdma_recv_done(struct ib_cq *cq, struct ib_wc *wc); static void nvmet_rdma_read_data_done(struct ib_cq *cq, struct ib_wc *wc); static void nvmet_rdma_qp_event(struct ib_event *event, void *priv); static void nvmet_rdma_queue_disconnect(struct nvmet_rdma_queue *queue); +static void nvmet_rdma_free_rsp(struct nvmet_rdma_device *ndev, + struct nvmet_rdma_rsp *r); +static int nvmet_rdma_alloc_rsp(struct nvmet_rdma_device *ndev, + struct nvmet_rdma_rsp *r); static const struct nvmet_fabrics_ops nvmet_rdma_ops; @@ -182,9 +186,17 @@ nvmet_rdma_get_rsp(struct nvmet_rdma_queue *queue) spin_unlock_irqrestore(&queue->rsps_lock, flags); if (unlikely(!rsp)) { - rsp = kmalloc(sizeof(*rsp), GFP_KERNEL); + int ret = -EINVAL; + + rsp = kzalloc(sizeof(*rsp), GFP_KERNEL); if (unlikely(!rsp)) return NULL; + ret = nvmet_rdma_alloc_rsp(queue->dev, rsp); + if (unlikely(ret)) { + kfree(rsp); + return NULL; + } + rsp->allocated = true; } @@ -197,6 +209,7 @@ nvmet_rdma_put_rsp(struct nvmet_rdma_rsp *rsp) unsigned long flags; if (unlikely(rsp->allocated)) { + nvmet_rdma_free_rsp(rsp->queue->dev, rsp); kfree(rsp); return; } -- 2.12.0

[PATCH v3.16 2/2] v4l: event: Add subscription to list before calling "add" operation

by Sakari Ailus

[ upstream commit 92539d3eda2c090b382699bbb896d4b54e9bdece ] Patch ad608fbcf166 changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails.

[regression] USB power management failure to suspend / high CPU usage

by Eric Blau

Hi folks, I noticed a regression introduced sometime after 4.19.4 in USB power management. I have a 2015 MacBook Pro. When I try to do a suspend or a suspend+hibernate, I get the following error messages trying to suspend usb2 and the suspend fails. This works fine in 4.19.4: Dec 22 13:50:36 eric-macbookpro kernel: Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. Dec 22 13:50:36 eric-macbookpro kernel: Suspending console(s) (use no_console_suspend to debug) Dec 22 13:50:36 eric-macbookpro kernel: dpm_run_callback(): usb_dev_freeze+0x0/0x10 returns -16 Dec 22 13:50:36 eric-macbookpro kernel: PM: Device usb2 failed to freeze async: error -16 Dec 22 13:50:38 eric-macbookpro systemd[1]: systemd-hybrid-sleep.service: Main process exited, code=exited, status=1/FAILURE Dec 22 13:50:38 eric-macbookpro systemd[1]: systemd-hybrid-sleep.service: Failed with result 'exit-code'. Dec 22 13:50:38 eric-macbookpro systemd[1]: Failed to start Hybrid Suspend+Hibernate. Dec 22 13:50:38 eric-macbookpro systemd[1]: Dependency failed for Hybrid Suspend+Hibernate. Dec 22 13:50:38 eric-macbookpro systemd[1]: hybrid-sleep.target: Job hybrid-sleep.target/start failed with result 'dependency'. Dec 22 13:50:38 eric-macbookpro systemd-logind[1573]: Operation 'sleep' finished. Dec 22 13:50:38 eric-macbookpro systemd[1]: Stopped target Sleep. The behavior exists in 4.19.8 and 4.19.11, the kernel versions I have upgraded to with Arch Linux, so the regression was introduced sometime between 4.19.4 and 4.19.8. Hibernate still works but when I resume from hibernate, there is a ksoftirqd and kworker thread/process together taking up 100% of one core. If I turn off auto power control for usb1 and usb2, the threads stop spinning. i.e., echo 'on' > '/sys/bus/usb/devices/usb1/power/control Any suggestions as to where this regression was introduced and what can be done to fix it? Thanks, Eric

[PATCH v2 1/1] scsi: Synchronize request queue PM status only on successful resume

by stanley.chu＠mediatek.com

From: Stanley Chu <stanley.chu(a)mediatek.com> The commit 356fd2663cff ("scsi: Set request queue runtime PM status back to active on resume") fixed up the inconsistent RPM status between request queue and device. However changing request queue RPM status shall be done only on successful resume, otherwise status may be still inconsistent as below, Request queue: RPM_ACTIVE Device: RPM_SUSPENDED This ends up soft lockup because requests can be submitted to underlying devices but those devices and their required resource are not resumed.

[PATCH 2/2] staging: rtl8188eu: Fix module loading from tasklet for WEP encryption

[PATCH] x86/retpoline: change RETPOLINE into CONFIG_RETPOLINE

by Nadav Amit

A recent enhancement intentionally fails the kernel build if the compiler does not support retpolines and CONFIG_RETPOLINE is set. However, the patch that introduced it did not change RETPOLINE macro references into CONFIG_RETPOLINE ones. As a result, indirect branches that are used by init functions are not kept (i.e., they use retpolines), and modules that do not use retpolines are marked as retpoline-safe. Fix it be changing RETPOLINE into CONFIG_RETPOLINE.

[PATCH v2] netfilter: xt_connlimit: fix race in connection counting

by Alakesh Haloi

An iptable rule like the following on a multicore systems will result in accepting more connections than set in the rule. iptables -A INPUT -p tcp -m tcp --syn --dport 7777 -m connlimit \ --connlimit-above 2000 --connlimit-mask 0 -j DROP In check_hlist function, connections that are found in saved connections but not in netfilter conntrack are deleted, assuming that those connections do not exist anymore. But for multi core systems, there exists a small time window, when a connection has been added to the xt_connlimit maintained rb-tree but has not yet made to netfilter conntrack table. This causes concurrent connections to return incorrect counts and go over limit set in iptable rule. The fix has been partially backported from the above mentioned upstream commit. Introduce timestamp and the owning cpu.

[PATCH] netfilter: xt_connlimit: fix race in connection counting

by Alakesh Haloi

An iptable rule like the following on a multicore systems will result in accepting more connections than set in the rule. iptables -A INPUT -p tcp -m tcp --syn --dport 7777 -m connlimit \ --connlimit-above 2000 --connlimit-mask 0 -j DROP In check_hlist function, connections that are found in saved connections but not in netfilter conntrack are deleted, assuming that those connections do not exist anymore. But for multi core systems, there exists a small time window, when a connection has been added to the xt_connlimit maintained rb-tree but has not yet made to netfilter conntrack table. This causes concurrent connections to return incorrect counts and go over limit set in iptable rule. Connection 1 on Core 1 Connection 2 on Core 2 list_length = N conntrack_table_len = N spin_lock_bh() In check_hlist() function a. loop over saved connections 1. call nf_conntrack_find_get() 2. If not found in 1, i. call hlist_del() b. return total count to caller c. connection gets added to list of saved connections. spin_unlock_bh() list_length = N + 1 spin_lock_bh() on core 2 In check_hlist() function a. loop over saved connection. 1. call nf_conntrack_find_get() 2. If not found in 1. i. call hlist_del() [Connection 1 was in the but not in nf_conntrack yet] ii. connection 1 gets deleted list_length = N conntrack_table_len = N b. return total count to caller c. connection 2 gets added to list of saved connections spin_unlock_bh() d. connection 1 gets added to nf_conntrack list_length = N + 1 conntrack_table_len = N + 1 e. connection 2 gets added to nf_conntrack list_length = N + 1 conntrack_table_len = N + 2 So we end up with N + 1 connections in the list but N + 2 in nf_conntrack, allowing more number of connections eventually than set in the rule. This fix adds an additional field to track such pending connections and prevent them from being deleted by another execution thread on a different core and returns correct count.

[PATCH 0/2] x86/mm/pkeys: fix user-visible pkey state destruction at fork()

by Dave Hansen

Hi x86 maintainers, This is an important fix that I believe needs to be merged for 4.21. Without it, applications calling fork() can potentially double-allocate a protection key, causing lots of strange problems. Thomas's Reviewed-by is on the the actual fix, but not the selftest. I would also be happy to send this as a pull request if you would prefer.
