[PATCH 2/3] ext4: fix potential race between s_group_info online resizing and access

by Suraj Jitindar Singh

During an online resize an array of pointers to s_group_info gets replaced so it can get enlarged. If there is a concurrent access to the array in ext4_get_group_info() and this memory has been reused then this can lead to an invalid memory access.

+ epoll-fix-possible-lost-wakeup-on-epoll_ctl-path.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: epoll: fix possible lost wakeup on epoll_ctl() path has been added to the -mm tree. Its filename is epoll-fix-possible-lost-wakeup-on-epoll_ctl-path.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/epoll-fix-possible-lost-wakeup-on-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/epoll-fix-possible-lost-wakeup-on-… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Roman Penyaev <rpenyaev(a)suse.de> Subject: epoll: fix possible lost wakeup on epoll_ctl() path This fixes possible lost wakeup introduced by commit a218cc491420. Originally modifications to ep->wq were serialized by ep->wq.lock, but in the a218cc491420 new rw lock was introduced in order to relax fd event path, i.e. callers of ep_poll_callback() function. After the change ep_modify and ep_insert (both are called on epoll_ctl() path) were switched to ep->lock, but ep_poll (epoll_wait) was using ep->wq.lock on wqueue list modification. The bug doesn't lead to any wqueue list corruptions, because wake up path and list modifications were serialized by ep->wq.lock internally, but actual waitqueue_active() check prior wake_up() call can be reordered with modifications of ep ready list, thus wake up can be lost. And yes, can be healed by explicit smp_mb(): list_add_tail(&epi->rdlink, &ep->rdllist); smp_mb(); if (waitqueue_active(&ep->wq)) wake_up(&ep->wp); But let's make it simple, thus current patch replaces ep->wq.lock with the ep->lock for wqueue modifications, thus wake up path always observes activeness of the wqueue correcty.

[PATCH 1/3] perf/amd/uncore: Replace manual sampling check with CAP_NO_INTERRUPT flag

This enables the sampling check in kernel/events/core.c's perf_event_open, which returns the more appropriate -EOPNOTSUPP.

The workload is : read/write/modifying ranges of memory and checking the contents. They : reported that within a few hours that a bad PMD would be reported followed : by a memory corruption where expected data was all zeros. A partial : report of the bad PMD looked like : : [ 5195.338482] ../mm/pgtable-generic.c:33: bad pmd ffff8888157ba008(000002e0396009e2) : [ 5195.341184] ------------[ cut here ]------------ : [ 5195.356880] kernel BUG at ../mm/pgtable-generic.c:35! : .... : [ 5195.410033] Call Trace: : [ 5195.410471] [<ffffffff811bc75d>] change_protection_range+0x7dd/0x930 : [ 5195.410716] [<ffffffff811d4be8>] change_prot_numa+0x18/0x30 : [ 5195.410918] [<ffffffff810adefe>] task_numa_work+0x1fe/0x310 : [ 5195.411200] [<ffffffff81098322>] task_work_run+0x72/0x90 : [ 5195.411246] [<ffffffff81077139>] exit_to_usermode_loop+0x91/0xc2 : [ 5195.411494] [<ffffffff81003a51>] prepare_exit_to_usermode+0x31/0x40 : [ 5195.411739] [<ffffffff815e56af>] retint_user+0x8/0x10 : : Decoding revealed that the PMD was a valid prot_numa PMD and the bad PMD : was a false detection. The bug does not trigger if automatic NUMA : balancing or transparent huge pages is disabled. : : The bug is due a race in change_pmd_range between a pmd_trans_huge and : pmd_nond_or_clear_bad check without any locks held. During the : pmd_trans_huge check, a parallel protection update under lock can have : cleared the PMD and filled it with a prot_numa entry between the transhuge : check and the pmd_none_or_clear_bad check. : : While this could be fixed with heavy locking, it's only necessary to make : a copy of the PMD on the stack during change_pmd_range and avoid races. A : new helper is created for this as the check if quite subtle and the : existing similar helpful is not suitable. This passed 154 hours of : testing (usually triggers between 20 minutes and 24 hours) without : detecting bad PMDs or corruption. A basic test of an autonuma-intensive : workload showed no significant change in behaviour. Although Mel withdrew the patch on the face of LKML comment https://lkml.org/lkml/2017/4/10/922 the race window aforementioned is still open, and we have reports of Linpack test reporting bad residuals after the bad PMD warning is observed. In addition to that, bad rss-counter and non-zero pgtables assertions are triggered on mm teardown for the task hitting the bad PMD. host kernel: mm/pgtable-generic.c:40: bad pmd 00000000b3152f68(8000000d2d2008e7) .... host kernel: BUG: Bad rss-counter state mm:00000000b583043d idx:1 val:512 host kernel: BUG: non-zero pgtables_bytes on freeing mm: 4096 The issue is observed on a v4.18-based distribution kernel, but the race window is expected to be applicable to mainline kernels, as well.

[PATCH v3] x86/cpu/amd: Enable the fixed Instructions Retired counter IRPERF

by Kim Phillips

Commit aaf248848db50 ("perf/x86/msr: Add AMD IRPERF (Instructions Retired) performance counter") added support for access to the free-running counter via 'perf -e msr/irperf/', but when exercised, we always get a 0 count: BEFORE: $ sudo perf stat -e instructions,msr/irperf/ true Performance counter stats for 'true': 624,833 instructions 0 msr/irperf/ Simply set its enable bit - HWCR bit 30 - to make it start counting. Enablement is restricted to all machines advertising IRPERF capability, except those susceptible to an erratum that makes the IRPERF return bad values. That erratum occurs in Family 17h models 00-1fh [1], but not in F17h models 20h and above [2]. AFTER (on a family 17h model 31h machine): $ sudo perf stat -e instructions,msr/irperf/ true Performance counter stats for 'true': 621,690 instructions 622,490 msr/irperf/ [1] Revision Guide for AMD Family 17h Models 00h-0Fh Processors [2] Revision Guide for AMD Family 17h Models 30h-3Fh Processors The revision guides are available from the bugzilla Link below.

[PATCH] MIPS: ingenic: DTS: Fix watchdog nodes

by Paul Cercueil

The devicetree ABI was broken on purpose by commit 6d532143c915 ("watchdog: jz4740: Use regmap provided by TCU driver"), and commit 1d9c30745455 ("watchdog: jz4740: Use WDT clock provided by TCU driver"). The commit message of the latter explains why the ABI was broken. However, the current devicetree files were not updated to the new ABI described in Documentation/devicetree/bindings/timer/ingenic,tcu.txt, so the watchdog driver would not probe. Fix this problem by updating the watchdog nodes to comply with the new ABI.

[PATCH] drm/sun4i: dsi: Avoid hotplug race with DRM driver bind

by Samuel Holland

We need to make sure that the DRM driver is fully registered before allowing the panel to be attached. Otherwise, we may trigger a hotplug event before sun4i_framebuffer_init() sets up drm->mode_config.funcs, causing a NULL pointer dereference.

[PATCH v3 1/3] powerpc/tm: Fix clearing MSR[TS] in current when reclaiming on signal delivery

by Gustavo Luiz Duarte

After a treclaim, we expect to be in non-transactional state. If we don't clear the current thread's MSR[TS] before we get preempted, then tm_recheckpoint_new_task() will recheckpoint and we get rescheduled in suspended transaction state. When handling a signal caught in transactional state, handle_rt_signal64() calls get_tm_stackpointer() that treclaims the transaction using tm_reclaim_current() but without clearing the thread's MSR[TS]. This can cause the TM Bad Thing exception below if later we pagefault and get preempted trying to access the user's sigframe, using __put_user(). Afterwards, when we are rescheduled back into do_page_fault() (but now in suspended state since the thread's MSR[TS] was not cleared), upon executing 'rfid' after completion of the page fault handling, the exception is raised because a transition from suspended to non-transactional state is invalid.

In order to make treclaim and clearing the thread's MSR[TS] atomic from a preemption perspective when CONFIG_PREEMPT is set, preempt_disable/enable() is used. It's also necessary to save the previous value of the thread's MSR before get_tm_stackpointer() is called so that it can be exposed to the signal handler later in setup_tm_sigcontexts() to inform the userspace MSR at the moment of the signal delivery. Found with tm-signal-context-force-tm kernel selftest. v3: Subject and comment improvements. v2: Fix build failure when tm is disabled.

[PATCH] usb: dwc3: gadget: Update chain bit correctly when using sg list

by John Stultz

From: Pratham Pratap <prathampratap(a)codeaurora.org> If scatter-gather operation is allowed, a large USB request is split into multiple TRBs. For preparing TRBs for sg list, driver iterates over the list and creates TRB for each sg and mark the chain bit to false for the last sg. The current IOMMU driver is clubbing the list of sgs which shares a page boundary into one and giving it to USB driver. With this the number of sgs mapped it not equal to the the number of sgs passed. Because of this USB driver is not marking the chain bit to false since it couldn't iterate to the last sg. This patch addresses this issue by marking the chain bit to false if it is the last mapped sg. At a practical level, this patch resolves USB transfer stalls seen with adb on dwc3 based db845c, pixel3 and other qcom hardware after functionfs gadget added scatter-gather support around v4.20. Credit also to Anurag Kumar Vulisha <anurag.kumar.vulisha(a)xilinx.com> who implemented a very similar fix to this issue.

[RHEL 8.2 PATCH] KVM: PPC: Book3S HV: XIVE: Ensure VP isn't already in use

by Daniel Henrique Barboza

From: Greg Kurz <groug(a)kaod.org> Bugzilla: 804424 Brew: 26599344 Upstream: Yes Tested: sanity tests in a Power 8 host Conflicts: none Connecting a vCPU to a XIVE KVM device means establishing a 1:1 association between a vCPU id and the offset (VP id) of a VP structure within a fixed size block of VPs. We currently try to enforce the 1:1 relationship by checking that a vCPU with the same id isn't already connected. This is good but unfortunately not enough because we don't map VP ids to raw vCPU ids but to packed vCPU ids, and the packing function kvmppc_pack_vcpu_id() isn't bijective by design. We got away with it because QEMU passes vCPU ids that fit well in the packing pattern. But nothing prevents userspace to come up with a forged vCPU id resulting in a packed id collision which causes the KVM device to associate two vCPUs to the same VP. This greatly confuses the irq layer and ultimately crashes the kernel, as shown below. Example: a guest with 1 guest thread per core, a core stride of 8 and 300 vCPUs has vCPU ids 0,8,16...2392. If QEMU is patched to inject at some point an invalid vCPU id 348, which is the packed version of itself and 2392, we get: genirq: Flags mismatch irq 199. 00010000 (kvm-2-2392) vs. 00010000

[PATCH 3/3] ext4: fix potential race between s_flex_groups online resizing and access

by Suraj Jitindar Singh

During an online resize an array of s_flex_groups structures gets replaced so it can get enlarged. If there is a concurrent access to the array and this memory has been reused then this can lead to an invalid memory access. The s_flex_group array has been converted into an array of pointers rather than an array of structures. This is to ensure that the information contained in the structures cannot get out of sync during a resize due to an accessor updating the value in the old structure after it has been copied but before the array pointer is updated. Since the structures them- selves are no longer copied but only the pointers to them this case is mitigated.

[PATCH v4 01/14] drm/i915: Fix sha_text population code

by Sean Paul

From: Sean Paul <seanpaul(a)chromium.org> This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported. Oh, and the sha_leftovers == 1 case works perfectly!

mmc patches for v5.4.y, v5.5.y

by Guenter Roeck

Hi Greg, please apply the following two patches to v5.4.y and v5.5.y to fix a problem when trying to boot various pxa machines from MMC. d3a5bcb4a17f gpio: add gpiod_toggle_active_low() 9073d10b0989 mmc: core: Rework wp-gpio handling The second patch fixes the problem, the first patch is necessary for the second patch to compile. Background: Commit 9073d10b0989 claims "No functional changes intended". However, it does include the following functional code change. --- a/drivers/mmc/host/pxamci.c +++ b/drivers/mmc/host/pxamci.c @@ -740,16 +740,16 @@ static int pxamci_probe(struct platform_device *pdev) goto out; } + if (!host->pdata->gpio_card_ro_invert) + mmc->caps2 |= MMC_CAP2_RO_ACTIVE_HIGH; + ret = mmc_gpiod_request_ro(mmc, "wp", 0, 0, NULL); if (ret && ret != -ENOENT) { dev_err(dev, "Failed requesting gpio_ro\n"); goto out; } - if (!ret) { + if (!ret) host->use_ro_gpio = true; - mmc->caps2 |= host->pdata->gpio_card_ro_invert ? - 0 : MMC_CAP2_RO_ACTIVE_HIGH; - } This _is_ a functional change: Previously, if there was no "ro" gpio pin, caps2 was never updated to active-high. This can have the practical effect of making the the card read-only, thus preventing the system from booting if it was mounted (and expected to be mounted) read-write. This is seen when trying to boot "spitz" and similar qemu machines from mmc. I bisected the problem to commit c914a27c92f91 ("mmc: pxamci: Support getting GPIO descs for RO and WP), affecting v5.0 and later kernels. Thanks, Guenter

[PATCH v2] mtd: spi-nor: Fixup page size for S25FS-S

by Alexander A Sverdlin

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> Spansion S25FS-S family has an issue in Basic Flash Parameter Table: DWORD-11 bits 7-4 specify write page size 512 bytes. In reality this is configurable in the non-volatile CR3NV register and even factory default configuration is "wrap at 256 bytes". So blind relying on BFPT breaks write operation on these Flashes. All this story is vendor-specific, so add the corresponding fixup hook which first restores the safe page size of 256 bytes from struct flash_info but checks is more performant 512 bytes configuration is active and adjusts the page_size accordingly.

PT_MAX_FULL_LEVELS is used to size the arrays that track guest pages table information, i.e. using a "max levels" of 4 causes KVM to access garbage beyond the end of an array when querying state for level 5 entries. E.g. FNAME(gpte_changed) will read garbage and most likely return %true for a level 5 entry, soft-hanging the guest because FNAME(fetch) will restart the guest instead of creating SPTEs because it thinks the guest PTE has changed. Note, KVM doesn't yet support 5-level nested EPT, so PT_MAX_FULL_LEVELS gets to stay "4" for the PTTYPE_EPT case. Fixes: 855feb673640 ("KVM: MMU: Add 5 level EPT & Shadow page table support.")

FAILED: patch "[PATCH] Btrfs: fix race between shrinking truncate and fiemap" failed to apply to 4.19-stable tree

This is generally harmless and at the moment the only consequences are missing file extent items representing holes after we expand the file size again after the truncate operation removed the prealloc extent items, and stale information for future fiemap calls (reporting extents that no longer exist or may have been reallocated to other files for example). Consider the following example: 1) Our inode has a size of 128KiB, one 128KiB extent at file offset 0 and a 1MiB prealloc extent at file offset 128KiB; 2) Task A starts doing a shrinking truncate of our inode to reduce it to a size of 64KiB. Before it searches the subvolume tree for file extent items to delete, it drops all the extent maps in the range from 64KiB to (u64)-1 by calling btrfs_drop_extent_cache(); 3) Task B starts doing a fiemap against our inode. When looking up for the inode's extent maps in the range from 128KiB to (u64)-1, it doesn't find any in the inode's extent map tree, since they were removed by task A. Because it didn't find any in the extent map tree, it scans the inode's subvolume tree for file extent items, and it finds the 1MiB prealloc extent at file offset 128KiB, then it creates an extent map based on that file extent item and adds it to inode's extent map tree (this ends up being done by btrfs_get_extent() <- btrfs_get_extent_fiemap() <- get_extent_skip_holes()); 4) Task A then drops the prealloc extent at file offset 128KiB and shrinks the 128KiB extent file offset 0 to a length of 64KiB. The truncation operation finishes and we end up with an extent map representing a 1MiB prealloc extent at file offset 128KiB, despite we don't have any more that extent; After this the two types of problems we have are: 1) Future calls to fiemap always report that a 1MiB prealloc extent exists at file offset 128KiB. This is stale information, no longer correct; 2) If the size of the file is increased, by a truncate operation that increases the file size or by a write into a file offset > 64KiB for example, we end up not inserting file extent items to represent holes for any range between 128KiB and 128KiB + 1MiB, since the hole expansion function, btrfs_cont_expand() will skip hole insertion for any range for which an extent map exists that represents a prealloc extent. This causes fsck to complain about missing file extent items when not using the NO_HOLES feature. The second issue could be often triggered by test case generic/561 from fstests, which runs fsstress and duperemove in parallel, and duperemove does frequent fiemap calls. Essentially the problems happens because fiemap does not acquire the inode's lock while truncate does, and fiemap locks the file range in the inode's iotree while truncate does not. So fix the issue by making btrfs_truncate_inode_items() lock the file range from the new file size to (u64)-1, so that it serializes with fiemap.

Random memory corruption may occur due to incorrent tlb flushes

by Santosh Sivaraj

Hi Greg/Sasha, The commit a46cc7a90fd (powerpc/mm/radix: Improve TLB/PWC flushes) picked up in 4.14 release has the potential to cause random memory corruption. This was fixed in 5.5 by the following patches. 12e4d53f3f powerpc/mmu_gather: enable RCU_TABLE_FREE even for !SMP case 0ed1325967 mm/mmu_gather: invalidate TLB correctly on batch allocation failure and flush 0758cd8304 asm-generic/tlb: avoid potential double flush It's a bit tricky to backport to 4.14 stable (though I have a backport to 4.19 stable, which I will post shortly). If you think it's important to fix this in 4.14, it would easier to revert the above mentioned commit (a46cc7a90fd). Please let me know your thoughts. Thanks, Santosh

[PATCH resend] mm, memcg: reset memcg's memory.{min, low} for reclaiming itself

by Yafang Shao

memory.{emin, elow} are set in mem_cgroup_protected(), and the values of them won't be changed until next recalculation in this function. After either or both of them are set, the next reclaimer to relcaim this memcg may be a different reclaimer, e.g. this memcg is also the root memcg of the new reclaimer, and then in mem_cgroup_protection() in get_scan_count() the old values of them will be used to calculate scan count, that is not proper. We should reset them to zero in this case. Here's an example of this issue. root_mem_cgroup / A memory.max=1024M memory.min=512M memory.current=800M Once kswapd is waked up, it will try to scan all MEMCGs, including this A, and it will assign memory.emin of A with 512M. After that, A may reach its hard limit(memory.max), and then it will do memcg reclaim. Because A is the root of this reclaimer, so it will not calculate its memory.emin. So the memory.emin is the old value 512M, and then this old value will be used in mem_cgroup_protection() in get_scan_count() to get the scan count. That is not proper.

[PATCH 0/2] serial: imx: Backport fixes for irq handling to v4.14

by Schrempf Frieder

From: Frieder Schrempf <frieder.schrempf(a)kontron.de> A customer of ours has problems with RS485 on i.MX6UL with the latest v4.14 kernel. They get an exception like below from time to time (the trace is from an older kernel, but the problem also exists in v4.14.170). As the cpuidle state 2 causes large delays for the interrupt that controls the RS485 RTS signal (which can lead to collisions on the bus), cpuidle state 2 was disabled on this system. This aspect might cause the exception happening more often on this system than on other systems with default cpuidle settings. Looking for solutions I found Uwe's patches that were applied in v4.17 being mentioned here [1] and here [2]. In [1] Uwe notes that backporting these fixes to v4.14 might not be trivial, but I tried and in my opinion found it not to be too problematic either. With the backported patches applied, our customer reports that the exceptions stopped occuring. Given this and the fact that the problem seems to be known and quite common, it would be nice to get this into the v4.14 stable tree.

[PATCH 4/8] net: ll_temac: Handle DMA halt condition caused by buffer underrun

by Esben Haabendal

The SDMA engine used by TEMAC halts operation when it has finished processing of the last buffer descriptor in the buffer ring. Unfortunately, no interrupt event is generated when this happens, so we need to setup another mechanism to make sure DMA operation is restarted when enough buffers have been added to the ring.

[PATCH 1/8] net: ll_temac: Fix race condition causing TX hang

by Esben Haabendal

It is possible that the interrupt handler fires and frees up space in the TX ring in between checking for sufficient TX ring space and stopping the TX queue in temac_start_xmit. If this happens, the queue wake from the interrupt handler will occur before the queue is stopped, causing a lost wakeup and the adapter's transmit hanging. To avoid this, after stopping the queue, check again whether there is sufficient space in the TX ring. If so, wake up the queue again. This is a port of the similar fix in axienet driver, commit 7de44285c1f6 ("net: axienet: Fix race condition causing TX hang").

PT_MAX_FULL_LEVELS is used to size the arrays that track guest pages table information, i.e. using a "max levels" of 4 causes KVM to access garbage beyond the end of an array when querying state for level 5 entries. E.g. FNAME(gpte_changed) will read garbage and most likely return %true for a level 5 entry, soft-hanging the guest because FNAME(fetch) will restart the guest instead of creating SPTEs because it thinks the guest PTE has changed. Note, KVM doesn't yet support 5-level nested EPT, so PT_MAX_FULL_LEVELS gets to stay "4" for the PTTYPE_EPT case. Fixes: 855feb673640 ("KVM: MMU: Add 5 level EPT & Shadow page table support.")

FAILED: patch "[PATCH] Btrfs: fix race between shrinking truncate and fiemap" failed to apply to 4.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.4-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 28553fa992cb28be6a65566681aac6cafabb4f2d Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Fri, 7 Feb 2020 12:23:09 +0000 Subject: [PATCH] Btrfs: fix race between shrinking truncate and fiemap When there is a fiemap executing in parallel with a shrinking truncate we can end up in a situation where we have extent maps for which we no longer have corresponding file extent items. This is generally harmless and at the moment the only consequences are missing file extent items representing holes after we expand the file size again after the truncate operation removed the prealloc extent items, and stale information for future fiemap calls (reporting extents that no longer exist or may have been reallocated to other files for example). Consider the following example: 1) Our inode has a size of 128KiB, one 128KiB extent at file offset 0 and a 1MiB prealloc extent at file offset 128KiB; 2) Task A starts doing a shrinking truncate of our inode to reduce it to a size of 64KiB. Before it searches the subvolume tree for file extent items to delete, it drops all the extent maps in the range from 64KiB to (u64)-1 by calling btrfs_drop_extent_cache(); 3) Task B starts doing a fiemap against our inode. When looking up for the inode's extent maps in the range from 128KiB to (u64)-1, it doesn't find any in the inode's extent map tree, since they were removed by task A. Because it didn't find any in the extent map tree, it scans the inode's subvolume tree for file extent items, and it finds the 1MiB prealloc extent at file offset 128KiB, then it creates an extent map based on that file extent item and adds it to inode's extent map tree (this ends up being done by btrfs_get_extent() <- btrfs_get_extent_fiemap() <- get_extent_skip_holes()); 4) Task A then drops the prealloc extent at file offset 128KiB and shrinks the 128KiB extent file offset 0 to a length of 64KiB. The truncation operation finishes and we end up with an extent map representing a 1MiB prealloc extent at file offset 128KiB, despite we don't have any more that extent; After this the two types of problems we have are: 1) Future calls to fiemap always report that a 1MiB prealloc extent exists at file offset 128KiB. This is stale information, no longer correct; 2) If the size of the file is increased, by a truncate operation that increases the file size or by a write into a file offset > 64KiB for example, we end up not inserting file extent items to represent holes for any range between 128KiB and 128KiB + 1MiB, since the hole expansion function, btrfs_cont_expand() will skip hole insertion for any range for which an extent map exists that represents a prealloc extent. This causes fsck to complain about missing file extent items when not using the NO_HOLES feature. The second issue could be often triggered by test case generic/561 from fstests, which runs fsstress and duperemove in parallel, and duperemove does frequent fiemap calls. Essentially the problems happens because fiemap does not acquire the inode's lock while truncate does, and fiemap locks the file range in the inode's iotree while truncate does not. So fix the issue by making btrfs_truncate_inode_items() lock the file range from the new file size to (u64)-1, so that it serializes with fiemap.

[PATCH v2 3/3] mtd: spinand: Don not erase the block before writing a bad block marker

by Schrempf Frieder

From: Frieder Schrempf <frieder.schrempf(a)kontron.de> Currently when marking a block, we use spinand_erase_op() to erase the block before writing the marker to the OOB area. Doing so without waiting for the operation to finish can lead to the marking failing silently and no bad block marker being written to the flash. In fact we don't need to do an erase at all before writing the BBM. The ECC is disabled for the raw access to the OOB data and we don't need to work around any issues with chips reporting ECC errors as it is known to be the case for raw NAND.

[PATCH] efi: READ_ONCE rng seed size before munmap

by Jason A. Donenfeld

This function is consistent with using size instead of seed->size (except for one place that this patch fixes), but it reads seed->size without using READ_ONCE, which means the compiler might still do something unwanted.

[PATCH v2 1/3] mtd: spinand: Stop using spinand->oobbuf for buffering bad block markers

by Schrempf Frieder

From: Frieder Schrempf <frieder.schrempf(a)kontron.de> For reading and writing the bad block markers, spinand->oobbuf is currently used as a buffer for the marker bytes. During the underlying read and write operations to actually get/set the content of the OOB area, the content of spinand->oobbuf is reused and changed by accessing it through spinand->oobbuf and/or spinand->databuf. This is a flaw in the original design of the SPI MEM core and at the latest from 13c15e07eedf ("mtd: spinand: Handle the case where PROGRAM LOAD does not reset the cache") on, it results in not having the bad block marker written at all, as the spinand->oobbuf is cleared to 0xff after setting the marker bytes to zero. To fix it, we now just store the two bytes for the marker on the stack and let the read/write operations copy it from/to the page buffer later.

[ Upstream commit f5de5b83303e61b1f3fb09bd77ce3ac2d7a475f2 ] In ubifs, concurrent execution of writepage and bulk read on the same file may cause ABBA deadlock, for example (Reproduce method see Link): Process A(Bulk-read starts from page4) Process B(write page4 back) vfs_read wb_workfn or fsync ... ... generic_file_buffered_read write_cache_pages ubifs_readpage LOCK(page4) ubifs_bulk_read ubifs_writepage LOCK(ui->ui_mutex) ubifs_write_inode ubifs_do_bulk_read LOCK(ui->ui_mutex) find_or_create_page(alloc page4) ↑ LOCK(page4) <-- ABBA deadlock occurs! In order to ensure the serialization execution of bulk read, we can't remove the big lock 'ui->ui_mutex' in ubifs_bulk_read().

For this particular test case, a combination of a few things caused the issue: - The cq ring was overflown - The request being canceled was in the overflow list The combination of the above means that the cq overflow list holds a reference to the request. The request is canceled correctly, but since the overflow list holds a reference to it, the final put won't happen. Since the final put doesn't happen, the request remains in the inflight. Hence we never finish the cancelation flush. Fix this by removing requests from the overflow list if we're canceling them.

[PATCH 3/3] mtd: spinand: Wait for the erase op to finish before writing a bad block marker

by Schrempf Frieder

From: Frieder Schrempf <frieder.schrempf(a)kontron.de> Currently when marking a block, we use spinand_erase_op() to erase the block before writing the marker to the OOB area without waiting for the operation to succeed. This can lead to the marking failing silently and no bad block marker being written to the flash. To fix this we reuse the spinand_erase() function, that already does everything we need to do before actually writing the marker.

[PATCH 1/3] mtd: spinand: Stop using spinand->oobbuf for buffering bad block markers

by Schrempf Frieder

From: Frieder Schrempf <frieder.schrempf(a)kontron.de> For reading and writing the bad block markers, spinand->oobbuf is currently used as a buffer for the marker bytes. During the underlying read and write operations to actually get/set the content of the OOB area, the content of spinand->oobbuf is reused and changed by accessing it through spinand->oobbuf and/or spinand->databuf. This is a flaw in the original design of the SPI MEM core and at the latest from 13c15e07eedf ("mtd: spinand: Handle the case where PROGRAM LOAD does not reset the cache") on, it results in not having the bad block marker written at all, as the spinand->oobbuf is cleared to 0xff after setting the marker bytes to zero. To fix it, we now just store the two bytes for the marker on the stack and let the read/write operations copy it from/to the page buffer later.

patch "USB: misc: iowarrior: add support for the 100 device" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: misc: iowarrior: add support for the 100 device to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

please cherry pick 75fea300d73a to 4.14.y

by Nick Desaulniers

Hi Greg, Sasha, Would you please cherry pick commit 75fea300d73a ("ARM: 8723/2: always assume the "unified" syntax for assembly code") which first landed in v4.16-rc1 into 4.14.y? In my experience, it cherry-picks cleanly. It fixes a stream of warnings we see when building 32b ARM kernels with Clang, like: /tmp/signal-1ac549.s: Assembler messages: /tmp/signal-1ac549.s:76: conditional infixes are deprecated in unified syntax We'll make immediate use of it in Android; if anyone objects to landing in stable let us know and we can carry it out of tree. -- Thanks, ~Nick Desaulniers

[stable 4.14 PATCH 1/3] arm64: cpufeature: Set the FP/SIMD compat HWCAP bits properly

by Suzuki K Poulose

commit 7ef1ab8792c50797c6c5c7c5150a02460 upstream We set the compat_elf_hwcap bits unconditionally on arm64 to include the VFP and NEON support. However, the FP/SIMD unit is optional on Arm v8 and thus could be missing. We already handle this properly in the kernel, but still advertise to the COMPAT applications that the VFP is available. Fix this to make sure we only advertise when we really have them.

[tip: ras/urgent] x86/mce/amd: Publish the bank pointer only after setup has succeeded

by tip-bot2 for Borislav Petkov

The following commit has been merged into the ras/urgent branch of tip: Commit-ID: 6e5cf31fbe651bed7ba1df768f2e123531132417 Gitweb: https://git.kernel.org/tip/6e5cf31fbe651bed7ba1df768f2e123531132417 Author: Borislav Petkov <bp(a)suse.de> AuthorDate: Tue, 04 Feb 2020 13:28:41 +01:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Thu, 13 Feb 2020 18:58:39 +01:00 x86/mce/amd: Publish the bank pointer only after setup has succeeded threshold_create_bank() creates a bank descriptor per MCA error thresholding counter which can be controlled over sysfs. It publishes the pointer to that bank in a per-CPU variable and then goes on to create additional thresholding blocks if the bank has such. However, that creation of additional blocks in allocate_threshold_blocks() can fail, leading to a use-after-free through the per-CPU pointer. Therefore, publish that pointer only after all blocks have been setup successfully.

[PATCH] x86/mce/amd: Fix kobject lifetime

by Borislav Petkov

From: Thomas Gleixner <tglx(a)linutronix.de> Accessing the MCA thresholding controls in sysfs concurrently with CPU hotplug can lead to a couple of KASAN-reported issues: BUG: KASAN: use-after-free in sysfs_file_ops+0x155/0x180 Read of size 8 at addr ffff888367578940 by task grep/4019 and BUG: KASAN: use-after-free in show_error_count+0x15c/0x180 Read of size 2 at addr ffff888368a05514 by task grep/4454 for example. Both result from the fact that the threshold block creation/teardown code frees the descriptor memory itself instead of defining proper ->release function and leaving it to the driver core to take care of that, after all sysfs accesses have completed. Do that and get rid of the custom freeing code, fixing the above UAFs in the process.

[PATCH AUTOSEL 4.4 001/100] drm/gma500: Fixup fbdev stolen size usage evaluation

by Sasha Levin

From: Paul Kocialkowski <paul.kocialkowski(a)bootlin.com> [ Upstream commit fd1a5e521c3c083bb43ea731aae0f8b95f12b9bd ] psbfb_probe performs an evaluation of the required size from the stolen GTT memory, but gets it wrong in two distinct ways: - The resulting size must be page-size-aligned; - The size to allocate is derived from the surface dimensions, not the fb dimensions. When two connectors are connected with different modes, the smallest will be stored in the fb dimensions, but the size that needs to be allocated must match the largest (surface) dimensions. This is what is used in the actual allocation code. Fix this by correcting the evaluation to conform to the two points above. It allows correctly switching to 16bpp when one connector is e.g. 1920x1080 and the other is 1024x768.

[PATCH v2 37/42] s390/uv: Fix handling of length extensions (already in s390 tree)

by Christian Borntraeger

The query parameter block might contain additional information and can be extended in the future. If the size of the block does not suffice we get an error code of rc=0x100. The buffer will contain all information up to the specified size and the hypervisor/guest simply do not need the additional information as they do not know about the new data. That means that we can (and must) accept rc=0x100 as success.

[PATCH AUTOSEL 4.9 001/141] drm/gma500: Fixup fbdev stolen size usage evaluation

by Sasha Levin

From: Paul Kocialkowski <paul.kocialkowski(a)bootlin.com> [ Upstream commit fd1a5e521c3c083bb43ea731aae0f8b95f12b9bd ] psbfb_probe performs an evaluation of the required size from the stolen GTT memory, but gets it wrong in two distinct ways: - The resulting size must be page-size-aligned; - The size to allocate is derived from the surface dimensions, not the fb dimensions. When two connectors are connected with different modes, the smallest will be stored in the fb dimensions, but the size that needs to be allocated must match the largest (surface) dimensions. This is what is used in the actual allocation code. Fix this by correcting the evaluation to conform to the two points above. It allows correctly switching to 16bpp when one connector is e.g. 1920x1080 and the other is 1024x768.

[PATCH v3 1/2] epoll: fix possible lost wakeup on epoll_ctl() path

by Roman Penyaev

This fixes possible lost wakeup introduced by the a218cc491420. Originally modifications to ep->wq were serialized by ep->wq.lock, but in the a218cc491420 new rw lock was introduced in order to relax fd event path, i.e. callers of ep_poll_callback() function. After the change ep_modify and ep_insert (both are called on epoll_ctl() path) were switched to ep->lock, but ep_poll (epoll_wait) was using ep->wq.lock on wqueue list modification. The bug doesn't lead to any wqueue list corruptions, because wake up path and list modifications were serialized by ep->wq.lock internally, but actual waitqueue_active() check prior wake_up() call can be reordered with modifications of ep ready list, thus wake up can be lost. And yes, can be healed by explicit smp_mb(): list_add_tail(&epi->rdlink, &ep->rdllist); smp_mb(); if (waitqueue_active(&ep->wq)) wake_up(&ep->wp); But let's make it simple, thus current patch replaces ep->wq.lock with the ep->lock for wqueue modifications, thus wake up path always observes activeness of the wqueue correcty.

[PATCH v1] can: j1939: transport: j1939_session_tx_dat(): fix use-after-free read in j1939_tp_txtimer()

by Oleksij Rempel

The current stack implementation do not support ECTS requests of not aligned TP sized blocks. If ECTS will request a block with size and offset spanning two TP blocks, this will cause memcpy() to read beyond the queued skb (which does only contain one TP sized block). Sometimes KASAN will detect this read if the memory region beyond the skb was previously allocated and freed. In other situations it will stay undetected. The ETP transfer in any case will be corrupted. This patch adds a sanity check to avoid this kind of read and abort the session with error J1939_XTP_ABORT_ECTS_TOO_BIG.

[RFT PATCH v2] xhci: Fix memory leak when caching protocol extended capability PSI tables

by Mathias Nyman

xhci driver assumed that xHC controllers have at most one custom supported speed table (PSI) for all usb 3.x ports. Memory was allocated for one PSI table under the xhci hub structure. Turns out this is not the case, some controllers have a separate "supported protocol capability" entry with a PSI table for each port. This means each usb3 roothub port can in theory support different custom speeds. To solve this, cache all supported protocol capabilities with their PSI tables in an array, and add pointers to the xhci port structure so that every port points to its capability entry in the array. When creating the SuperSpeedPlus USB Device Capability BOS descriptor for the xhci USB 3.1 roothub we for now will use only data from the first USB 3.1 capable protocol capability entry in the array. This could be improved later, this patch focuses resolving the memory leak.

[PATCH stable] crypto: chacha20poly1305 - prevent integer overflow on large input

by Jason A. Donenfeld

This code assigns src_len (size_t) to sl (int), which causes problems when src_len is very large. Probably nobody in the kernel should be passing this much data to chacha20poly1305 all in one go anyway, so I don't think we need to change the algorithm or introduce larger types or anything. But we should at least error out early in this case and print a warning so that we get reports if this does happen and can look into why anybody is possibly passing it that much data or if they're accidently passing -1 or similar.

This affects the overall reclaiming behavior: The corresponding LRU list is eligible for reclaiming only when its size logically right shifted by @sc->priority is bigger than zero in the former formula. For example, the inactive anonymous LRU list should have at least 0x4000 pages to be eligible for reclaiming when we have 60/12 for swappiness/priority and without taking scan/rotation ratio into account. After the roundup is applied, the inactive anonymous LRU list becomes eligible for reclaiming when its size is bigger than or equal to 0x1000 in the same condition. (0x4000 >> 12) * 60 / (60 + 140 + 1) = 1 ((0x1000 >> 12) * 60) + 200) / (60 + 140 + 1) = 1 aarch64 has 512MB huge page size when the base page size is 64KB. The memory cgroup that has a huge page is always eligible for reclaiming in that case. The reclaiming is likely to stop after the huge page is reclaimed, meaing the further iteration on @sc->priority and the silbing and child memory cgroups will be skipped. The overall behaviour has been changed. This fixes the issue by applying the roundup to offlined memory cgroups only, to give more preference to reclaim memory from offlined memory cgroup. It sounds reasonable as those memory is unlikedly to be used by anyone. The issue was found by starting up 8 VMs on a Ampere Mustang machine, which has 8 CPUs and 16 GB memory. Each VM is given with 2 vCPUs and 2GB memory. It took 264 seconds for all VMs to be completely up and 784MB swap is consumed after that. With this patch applied, it took 236 seconds and 60MB swap to do same thing. So there is 10% performance improvement for my case.

[PATCH] ARM: dts: ls1021a: Restore MDIO compatible to gianfar

by Vladimir Oltean

The difference between "fsl,etsec2-mdio" and "gianfar" has to do with the .get_tbipa function, which calculates the address of the TBIPA register automatically, if not explicitly specified. [ see drivers/net/ethernet/freescale/fsl_pq_mdio.c ]. On LS1021A, the TBIPA register is at offset 0x30 within the port register block, which is what the "gianfar" method of calculating addresses actually does. Luckily, the bad "compatible" is inconsequential for ls1021a.dtsi, because the TBIPA register is explicitly specified via the second "reg" (<0x0 0x2d10030 0x0 0x4>), so the "get_tbipa" function is dead code. Nonetheless it's good to restore it to its correct value.

patch "vt: selection, close sel_buffer race" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled vt: selection, close sel_buffer race to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 07e6124a1a46b4b5a9b3cacc0c306b50da87abf5 Mon Sep 17 00:00:00 2001 From: Jiri Slaby <jslaby(a)suse.cz> Date: Mon, 10 Feb 2020 09:11:31 +0100 Subject: vt: selection, close sel_buffer race syzkaller reported this UAF: BUG: KASAN: use-after-free in n_tty_receive_buf_common+0x2481/0x2940 drivers/tty/n_tty.c:1741 Read of size 1 at addr ffff8880089e40e9 by task syz-executor.1/13184 CPU: 0 PID: 13184 Comm: syz-executor.1 Not tainted 5.4.7 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 Call Trace: ... kasan_report+0xe/0x20 mm/kasan/common.c:634 n_tty_receive_buf_common+0x2481/0x2940 drivers/tty/n_tty.c:1741 tty_ldisc_receive_buf+0xac/0x190 drivers/tty/tty_buffer.c:461 paste_selection+0x297/0x400 drivers/tty/vt/selection.c:372 tioclinux+0x20d/0x4e0 drivers/tty/vt/vt.c:3044 vt_ioctl+0x1bcf/0x28d0 drivers/tty/vt/vt_ioctl.c:364 tty_ioctl+0x525/0x15a0 drivers/tty/tty_io.c:2657 vfs_ioctl fs/ioctl.c:47 [inline] It is due to a race between parallel paste_selection (TIOCL_PASTESEL) and set_selection_user (TIOCL_SETSEL) invocations. One uses sel_buffer, while the other frees it and reallocates a new one for another selection. Add a mutex to close this race. The mutex takes care properly of sel_buffer and sel_buffer_lth only. The other selection global variables (like sel_start, sel_end, and sel_cons) are protected only in set_selection_user. The other functions need quite some more work to close the races of the variables there. This is going to happen later. This likely fixes (I am unsure as there is no reproducer provided) bug 206361 too. It was marked as CVE-2020-8648.

But signals are not handled at all. Normally, this is not a problem as tty_ldisc_receive_buf receives all the goods and a user has no reason to interrupt the task. There are two scenarios where this matters: 1) when the tty is throttled and a signal is sent to the process, it spins on a CPU until the tty is unthrottled. schedule() does not really echedule, but returns immediately, of course. 2) when the sel_buffer becomes invalid, KASAN prevents any reads from it and the loop simply does not proceed and spins forever (causing the tty to throttle, but the code never sleeps, the same as above). This sometimes happens as there is a race in the sel_buffer handling code. So add signal handling to this ioctl (TIOCL_PASTESEL) and return -EINTR in case a signal is pending.

[PATCH] crypto: chacha20poly1305 - prevent integer overflow on large input

by Jason A. Donenfeld

This code assigns src_len (size_t) to sl (int), which causes problems when src_len is very large. Probably nobody in the kernel should be passing this much data to chacha20poly1305 all in one go anyway, so I don't think we need to change the algorithm or introduce larger types or anything. But we should at least error out early in this case and print a warning so that we get reports if this does happen and can look into why anybody is possibly passing it that much data or if they're accidently passing -1 or similar.

Donenfeld <Jason(a)zx2c4.com> Acked-by: Ard Biesheuvel <ardb(a)kernel.org> --- Due to the "stable" in the subject line prior, this patch missed Herbert's filters.

patch "usb: dwc3: gadget: Check for IOC/LST bit in TRB->ctrl fields" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: dwc3: gadget: Check for IOC/LST bit in TRB->ctrl fields to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 5ee858975b13a9b40db00f456989a689fdbb296c Mon Sep 17 00:00:00 2001 From: Anurag Kumar Vulisha <anurag.kumar.vulisha(a)xilinx.com> Date: Mon, 27 Jan 2020 19:30:46 +0000 Subject: usb: dwc3: gadget: Check for IOC/LST bit in TRB->ctrl fields The current code in dwc3_gadget_ep_reclaim_completed_trb() will check for IOC/LST bit in the event->status and returns if IOC/LST bit is set. This logic doesn't work if multiple TRBs are queued per request and the IOC/LST bit is set on the last TRB of that request. Consider an example where a queued request has multiple queued TRBs and IOC/LST bit is set only for the last TRB. In this case, the core generates XferComplete/XferInProgress events only for the last TRB (since IOC/LST are set only for the last TRB). As per the logic in dwc3_gadget_ep_reclaim_completed_trb() event->status is checked for IOC/LST bit and returns on the first TRB. This leaves the remaining TRBs left unhandled. Similarly, if the gadget function enqueues an unaligned request with sglist already in it, it should fail the same way, since we will append another TRB to something that already uses more than one TRB. To aviod this, this patch changes the code to check for IOC/LST bits in TRB->ctrl instead. At a practical level, this patch resolves USB transfer stalls seen with adb on dwc3 based HiKey960 after functionfs gadget added scatter-gather support around v4.20.

[PATCH v2] ext4: Fix checksum errors with indexed dirs

by Jan Kara

DIR_INDEX has been introduced as a compat ext4 feature. That means that even kernels / tools that don't understand the feature may modify the filesystem. This works because for kernels not understanding indexed dir format, internal htree nodes appear just as empty directory entries. Index dir aware kernels then check the htree structure is still consistent before using the data. This all worked reasonably well until metadata checksums were introduced. The problem is that these effectively made DIR_INDEX only ro-compatible because internal htree nodes store checksums in a different place than normal directory blocks. Thus any modification ignorant to DIR_INDEX (or just clearing EXT4_INDEX_FL from the inode) will effectively cause checksum mismatch and trigger kernel errors. So we have to be more careful when dealing with indexed directories on filesystems with checksumming enabled. 1) We just disallow loading any directory inodes with EXT4_INDEX_FL when DIR_INDEX is not enabled. This is harsh but it should be very rare (it means someone disabled DIR_INDEX on existing filesystem and didn't run e2fsck), e2fsck can fix the problem, and we don't want to answer the difficult question: "Should we rather corrupt the directory more or should we ignore that DIR_INDEX feature is not set?" 2) When we find out htree structure is corrupted (but the filesystem and the directory should in support htrees), we continue just ignoring htree information for reading but we refuse to add new entries to the directory to avoid corrupting it more.

[PATCH 4.19] scsi: megaraid_sas: Do not initiate OCR if controller is not in ready state

by Anand Lodnoor

commit 6d7537270e3283b92f9b327da9d58a4de40fe8d0 upstream. Driver initiates OCR if a DCMD command times out. But there is a deadlock if the driver attempts to invoke another OCR before the mutex lock (reset_mutex) is released from the previous session of OCR. This patch takes care of the above scenario using new flag MEGASAS_FUSION_OCR_NOT_POSSIBLE to indicate if OCR is possible.

[PATCH] drm/i915/dsc: force full modeset whenever DSC is enabled at probe

by Jani Nikula

We lack full state readout of DSC config, which may lead to DSC enable using a config that's all zeros, failing spectacularly. Force full modeset and thus compute config at probe to get a sane state, until we implement DSC state readout. Any fastset that did appear to work with DSC at probe, worked by coincidence. [1] is an example of a change that triggered the issue on TGL DSI DSC.

patch "USB: serial: ch341: fix receiver regression" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: ch341: fix receiver regression to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 7c3d02285ad558691f27fde760bcd841baa27eab Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Thu, 6 Feb 2020 12:18:19 +0100 Subject: USB: serial: ch341: fix receiver regression While assumed not to make a difference, not using the factor-2 prescaler makes the receiver more susceptible to errors. Specifically, there have been reports of problems with devices that cannot generate a 115200 rate with a smaller error than 2.1% (e.g. 117647 bps). But this can also be reproduced with a low-speed RS232 tranceiver at 115200 when the input rate matches the nominal rate. So whenever possible, enable the factor-2 prescaler and halve the divisor in order to use settings closer to that of the previous algorithm.

[PATCH] venus: cache vb payload to be used by clock scaling

by Stanimir Varbanov

Instead of iterate over previously queued buffers in clock scaling code do cache the payload in instance context structure for later use when calculating new clock rate. This will avoid to use spin locks during buffer list iteration in clock_scaling.
