FAILED: patch "[PATCH] cpufreq / CPPC: Set platform specific transition_delay_us" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-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 d4f3388afd488ed15368fa7413b8bd6d1f98bb1d Mon Sep 17 00:00:00 2001 From: Prashanth Prakash <pprakash(a)codeaurora.org> Date: Fri, 27 Apr 2018 11:35:27 -0600 Subject: [PATCH] cpufreq / CPPC: Set platform specific transition_delay_us Add support to specify platform specific transition_delay_us instead of using the transition delay derived from PCC. With commit 3d41386d556d (cpufreq: CPPC: Use transition_delay_us depending transition_latency) we are setting transition_delay_us directly and not applying the LATENCY_MULTIPLIER. Because of that, on Qualcomm Centriq we can end up with a very high rate of frequency change requests when using the schedutil governor (default rate_limit_us=10 compared to an earlier value of 10000). The PCC subspace describes the rate at which the platform can accept commands on the CPPC's PCC channel. This includes read and write command on the PCC channel that can be used for reasons other than frequency transitions. Moreover the same PCC subspace can be used by multiple freq domains and deriving transition_delay_us from it as we do now can be sub-optimal. Moreover if a platform does not use PCC for desired_perf register then there is no way to compute the transition latency or the delay_us. CPPC does not have a standard defined mechanism to get the transition rate or the latency at the moment. Given the above limitations, it is simpler to have a platform specific transition_delay_us and rely on PCC derived value only if a platform specific value is not available.

This turns out to be a regression for some applications, notably Postgres. Before errseq_t, a writeback error would be reported exactly once (as long as the inode remained in memory), so Postgres could open a file, call fsync() and find out whether there had been a writeback error on that file from another process. This patch changes the errseq infrastructure to report errors to all file descriptors which are opened after the error occurred, but before it was reported to any file descriptor. This restores the user-visible behaviour.

[PATCH] [stable] arm64: Add work around for Arm Cortex-A55 Erratum 1024718

by Suzuki K Poulose

commit ece1397cbc89c51914fae1aec729539cfd8bd62b upstream Some variants of the Arm Cortex-55 cores (r0p0, r0p1, r1p0) suffer from an erratum 1024718, which causes incorrect updates when DBM/AP bits in a page table entry is modified without a break-before-make sequence. The work around is to disable the hardware DBM feature on the affected cores. The hardware Access Flag management features is not affected. The hardware DBM feature is a non-conflicting capability, i.e, the kernel could handle cores using the feature and those without having the features running at the same time. So this work around is detected at early boot time, rather than delaying it until the CPUs are brought up into the kernel with MMU turned on. This also avoids other complexities with late CPUs turning online, with or without the hardware DBM features. Note: The upstream commit is on top of a reworked capability infrastructure for arm64 heterogeneous systems, which allows handling this later in the boot process. This backport is based on the original version of the patch [0]. Folded the 3 patches into this single commit, removing the unncessary bits.

v4.4-stable: GPMI nand controller broken

by Sascha Hauer

The following went into v4.4.120: 197190bc5c48 mtd: nand: gpmi: Fix failure when a erased page has a bitflip at BBM This patch was backported to far for the stable tree. It only makes sense (and only works) together with: bd2e778c9ee3 gpmi-nand: Handle ECC Errors in erased pages which first appeared in v4.7. So either we revert 197190bc5c48 on the v4.4 stable tree or we apply the attached patch which is a backport of bd2e778c9ee3 for v4.4. I don't know which solution is prefered, personally I would prefer applying the attached patch which is also a bugfix. Without it erased pages may not be handled properly. Sascha ---------------------------8<------------------------------- >From ec42023a83778e524a024bdd25d970b8dc7a3966 Mon Sep 17 00:00:00 2001 From: Markus Pargmann <mpa(a)pengutronix.de> Date: Mon, 25 Apr 2016 14:35:12 +0200 Subject: [PATCH] gpmi-nand: Handle ECC Errors in erased pages ECC is only calculated for written pages. As erased pages are not actively written the ECC is always invalid. For this purpose the Hardware BCH unit is able to check for erased pages and does not raise an ECC error in this case. This behaviour can be influenced using the BCH_MODE register which sets the number of allowed bitflips in an erased page. Unfortunately the unit is not capable of fixing the bitflips in memory. To avoid complete software checks for erased pages, we can simply check buffers with uncorrectable ECC errors because we know that any erased page with errors is uncorrectable by the BCH unit. This patch adds the generic nand_check_erased_ecc_chunk() to gpmi-nand to correct erased pages.

[PATCH] orangefs: set i_size on new symlink

by Martin Brandenburg

As long as a symlink inode remains in-core, the destination (and therefore size) will not be re-fetched from the server, as it cannot change. The original implementation of the attribute cache assumed that setting the expiry time in the past was sufficient to cause a re-fetch of all attributes on the next getattr. That does not work in this case. The bug manifested itself as follows. When the command sequence touch foo; ln -s foo bar; ls -l bar is run, the output was lrwxrwxrwx. 1 fedora fedora 4906 Apr 24 19:10 bar -> foo However, after a re-mount, ls -l bar produces lrwxrwxrwx. 1 fedora fedora 3 Apr 24 19:10 bar -> foo After this commit, even before a re-mount, the output is lrwxrwxrwx. 1 fedora fedora 3 Apr 24 19:10 bar -> foo Reported-by: Becky Ligon <ligon(a)clemson.edu> Signed-off-by: Martin Brandenburg <martin(a)omnibond.com> Fixes: 71680c18c8f2 ("orangefs: Cache getattr results.")

Please consider commit ac1e55b1fdb27c1b07a0a6fe519f1291ff1e7d40 ACPI / button: make module loadable when booted in non-ACPI mode at least for v4.16-stable. It likely applies much further back, but the relevance of v4.16 is that it is used in Fedora 28, and without this patch, arm64 systems booting in DT mode cannot run a desktop GUI on F28 if they rely on the nouveau driver.

[PATCH 1/2] KVM: ARM: Properly protect VGIC locks from IRQs

by Andre Przywara

As Jan reported [1], lockdep complains about the VGIC not being bullet proof. This seems to be due to two issues: - When commit 006df0f34930 ("KVM: arm/arm64: Support calling vgic_update_irq_pending from irq context") promoted irq_lock and ap_list_lock to _irqsave, we forgot two instances of irq_lock. lockdeps seems to pick those up. - If a lock is _irqsave, any other locks we take inside them should be _irqsafe as well. So the lpi_list_lock needs to be promoted also. This fixes both issues by simply making the remaining instances of those locks _irqsave. One irq_lock is addressed in a separate patch, to simplify backporting.

[PATCH v3] PCI / PM: Always check PME wakeup capability for runtime wakeup support

by Kai-Heng Feng

USB controller ASM1042 stops working after commit de3ef1eb1cd0 ("PM / core: Drop run_wake flag from struct dev_pm_info"). The device in question is not power managed by platform firmware, furthermore, it only supports PME# from D3cold: Capabilities: [78] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot-,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Before commit de3ef1eb1cd0, the device never gets runtime suspended. After that commit, the device gets runtime suspended, so it does not respond to any PME#. usb_hcd_pci_probe() mandatorily calls device_wakeup_enable(), hence device_can_wakeup() in pci_dev_run_wake() always returns true. So pci_dev_run_wake() needs to check PME wakeup capability as its first condition. In addition, change wakeup flag passed to pci_target_state() from false to true, because we want to find the deepest state that the device can still generate PME#.

Bisecting pointed me to the commit 2417da3f4d6bc ("ipv6: only call ip6_route_dev_notify() once for NETDEV_UNREGISTER") [0] which is backport of upstream 76da0704507bb. That backported commit has appeared in a 4.4.103. I use OpenWrt/LEDE [1] distribution and LXC [2] 1.1.5. After stopping a container I start getting these messages: [ 229.419188] unregister_netdevice: waiting for lo to become free. Usage count = 1 [ 239.660408] unregister_netdevice: waiting for lo to become free. Usage count = 1 [ 249.839189] unregister_netdevice: waiting for lo to become free. Usage count = 1 (...) Trying to start LXC nevertheless results in lxc-start command hang around network configuration. Trying to query LXC state afterwards results in a lxc-info command hang too. I tried Googling for this issue and found similar reports: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1729637 https://github.com/fnproject/fn/issues/686 https://lime-technology.com/forums/topic/66863-kernelunregister_netdevice-w… all of them related to the Docker, which is probably a similar use case to the LXC. I couldn't find any reference to commit 76da0704507bb that could suggest fixing the problem I'm seeing. Does anyone have an idea what is the issue I'm seeing about? Or even better, how to fix it?

[PATCH 1/1] xhci: Fix use-after-free in xhci_free_virt_device

by Mathias Nyman

KASAN found a use-after-free in xhci_free_virt_device+0x33b/0x38e where xhci_free_virt_device() sets slot id to 0 if udev exists: if (dev->udev && dev->udev->slot_id) dev->udev->slot_id = 0; dev->udev will be true even if udev is freed because dev->udev is not set to NULL. set dev->udev pointer to NULL in xhci_free_dev() The original patch went to stable so this fix needs to be applied there as well.

These patches fix two issues reported[1] a while back by Joe and Andrea around how shmat(2) behaves with nil-page. The first reverts a commit that it was incorrectly thought that mapping nil-page (address=0) was a no no with MAP_FIXED. This is not the case, with the exception of SHM_REMAP; which is address in the second patch. I chose two patches because it is easier to backport and it explicitly reverts bogus behaviour. Both patches ought to be in -stable and ltp testcases need updated (the added testcase around the cve can be modified to just test for SHM_RND|SHM_REMAP). [1] lkml.kernel.org/r/20180430172152.nfa564pvgpk3ut7p@linux-n805 This patch (of 2): 95e91b831f87 (ipc/shm: Fix shmat mmap nil-page protection) worked on the idea that we should not be mapping as root addr=0 and MAP_FIXED. However, it was reported that this scenario is in fact valid, thus making the patch both bogus and breaks userspace as well. For example X11's libint10.so relies on shmat(1, SHM_RND) for lowmem initialization[1].

[PATCH for-rc v2 0/6] IB/hfi1,rdmavt: Fixes for the 4.17 RC

by Dennis Dalessandro

Hi Jason and Doug, Here are 6 patches that might make the bar for RC. The first patch fixes something that came in pretty recently, I beleive 4.13. The second patch is trivial, but does modify user visible text. Patch 3 looks large but it's mostly comments. It just moves code. Patch 4 is also pretty simple. The last two patches fix memory leaks. If you don't think these pass muster for RC please carry over to for-next. Changes since V1: Correct version tag so it shows up as for-rc in patchworks. --- Michael J.

[PATCH 4.9] arm/arm64: KVM: Add PSCI version selection API

by Marc Zyngier

commit 85bd0ba1ff9875798fad94218b627ea9f768f3c3 upstream. Although we've implemented PSCI 0.1, 0.2 and 1.0, we expose either 0.1 or 1.0 to a guest, defaulting to the latest version of the PSCI implementation that is compatible with the requested version. This is no different from doing a firmware upgrade on KVM. But in order to give a chance to hypothetical badly implemented guests that would have a fit by discovering something other than PSCI 0.2, let's provide a new API that allows userspace to pick one particular version of the API. This is implemented as a new class of "firmware" registers, where we expose the PSCI version. This allows the PSCI version to be save/restored as part of a guest migration, and also set to any supported version if the guest requires it.

patch "USB: Accept bulk endpoints with 1024-byte maxpacket" 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: Accept bulk endpoints with 1024-byte maxpacket 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 fb5ee84ea72c5f1b6cabdd1c9d6e8648995ca7c6 Mon Sep 17 00:00:00 2001 From: Alan Stern <stern(a)rowland.harvard.edu> Date: Thu, 3 May 2018 11:04:48 -0400 Subject: USB: Accept bulk endpoints with 1024-byte maxpacket Some non-compliant high-speed USB devices have bulk endpoints with a 1024-byte maxpacket size. Although such endpoints don't work with xHCI host controllers, they do work with EHCI controllers. We used to accept these invalid sizes (with a warning), but we no longer do because of an unintentional change introduced by commit aed9d65ac327 ("USB: validate wMaxPacketValue entries in endpoint descriptors"). This patch restores the old behavior, so that people with these peculiar devices can use them without patching their kernels by hand.

4.14.y needs commit 71546d100422b

by Guenter Roeck

Hi Greg, please pull commit 71546d100422b ("percpu: include linux/sched.h for cond_resched()") into v4.14.y to avoid build errors for microblaze and other architectures. Also, with that many patches queued, can we possibly get more than the usual number of days for testing the next round of stable releases ? Thanks, Guenter

[PATCH v4][for 4.17-rc3] cpufreq / CPPC: Set platform specific transition_delay_us

by Prashanth Prakash

Add support to specify platform specific transition_delay_us instead of using the transition delay derived from PCC. With commit "3d41386d556d: cpufreq: CPPC: Use transition_delay_us depending transition_latency" we are setting transition_delay_us directly and not applying the LATENCY_MULTIPLIER. With this on Qualcomm Centriq we can end up with a very high rate of frequency change requests when using schedutil governor (default rate_limit_us=10 compared to an earlier value of 10000). The PCC subspace describes the rate at which the platform can accept commands on the CPPC's PCC channel. This includes read and write command on the PCC channel that can be used for reasons other than frequency transitions. Moreover the same PCC subspace can be used by multiple freq domains and deriving transition_delay_us from it as we do now can be sub-optimal. Moreover if a platform does not use PCC for desired_perf register then there is no way to compute the transition latency or the delay_us. CPPC does not have a standard defined mechanism to get the transition rate or the latency at the moment. Given the above limitations, it is simpler to have a platform specific transition_delay_us and rely on PCC derived value only if a platform specific value is not available.

[PATCH] drm/atomic: Clean old_state/new_state in drm_atomic_state_default_clear()

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Clear the old_state and new_state pointers for every object in drm_atomic_state_default_clear(). Otherwise drm_atomic_get_{new,old}_*_state() will hand out stale pointers to anyone who hasn't first confirmed that the object is in fact part of the current atomic transcation, if they are called after we've done the ww backoff dance while hanging on to the same drm_atomic_state. For example, handle_conflicting_encoders() looks like it could hit this since it iterates the full connector list and just calls drm_atomic_get_new_connector_state() for each. And I believe we have now witnessed this happening at least once in i915 check_digital_port_conflicts(). Commit 8b69449d2663 ("drm/i915: Remove last references to drm_atomic_get_existing* macros") changed the safe drm_atomic_get_existing_connector_state() to the unsafe drm_atomic_get_new_connector_state(), which opened the doors for this particular bug there as well.

[PATCH 1/1] xhci: Fix use-after-free in xhci_free_virt_device

by Mathias Nyman

KASAN found a use-after-free in xhci_free_virt_device+0x33b/0x38e where xhci_free_virt_device() sets slot id to 0 if udev exists: if (dev->udev && dev->udev->slot_id) dev->udev->slot_id = 0; dev->udev will be true even if udev is freed because dev->udev is not set to NULL. set dev->udev pointer to NULL in xhci_free_dev() The original patch went to stable so this fix needs to be applied there as well.

[PATCH AUTOSEL for 4.14 001/161] firewire-ohci: work around oversized DMA reads on JMicron controllers

by Sasha Levin

From: Hector Martin <marcan(a)marcan.st> [ Upstream commit 188775181bc05f29372b305ef96485840e351fde ] At least some JMicron controllers issue buggy oversized DMA reads when fetching context descriptors, always fetching 0x20 bytes at once for descriptors which are only 0x10 bytes long. This is often harmless, but can cause page faults on modern systems with IOMMUs: DMAR: [DMA Read] Request device [05:00.0] fault addr fff56000 [fault reason 06] PTE Read access is not set firewire_ohci 0000:05:00.0: DMA context IT0 has stopped, error code: evt_descriptor_read This works around the problem by always leaving 0x10 padding bytes at the end of descriptor buffer pages, which should be harmless to do unconditionally for controllers in case others have the same behavior.

[PATCH 4.9.y, 4.14.y] crypto: talitos - fix IPsec cipher in length

by Horia Geantă

commit 2b1227301a8e4729409694e323b72c064c47cb6b upstream. For SEC 2.x+, cipher in length must contain only the ciphertext length. In case of using hardware ICV checking, the ICV length is provided via the "extent" field of the descriptor pointer.

[PATCH v2] libata: blacklist Micron SSD

by Sudip Mukherjee

From: Sudip Mukherjee <sudipm.mukherjee(a)gmail.com> While whitelisting Micron M500DC drives, the tweaked blacklist entry enabled queued TRIM for M500IT variants also. But these do not support queued TRIM. And while using those SSDs with the latest kernel we have seen errors and even the partition table getting corrupted. Some part from the dmesg: [ 6.727384] ata1.00: ATA-9: Micron_M500IT_MTFDDAK060MBD, MU01, max UDMA/133 [ 6.727390] ata1.00: 117231408 sectors, multi 16: LBA48 NCQ (depth 31/32), AA [ 6.741026] ata1.00: supports DRM functions and may not be fully accessible [ 6.759887] ata1.00: configured for UDMA/133 [ 6.762256] scsi 0:0:0:0: Direct-Access ATA Micron_M500IT_MT MU01 PQ: 0 ANSI: 5 and then for the error: [ 120.860334] ata1.00: exception Emask 0x1 SAct 0x7ffc0007 SErr 0x0 action 0x6 frozen [ 120.860338] ata1.00: irq_stat 0x40000008 [ 120.860342] ata1.00: failed command: SEND FPDMA QUEUED [ 120.860351] ata1.00: cmd 64/01:00:00:00:00/00:00:00:00:00/a0 tag 0 ncq dma 512 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x5 (timeout) [ 120.860353] ata1.00: status: { DRDY } [ 120.860543] ata1: hard resetting link [ 121.166128] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 121.166376] ata1.00: supports DRM functions and may not be fully accessible [ 121.186238] ata1.00: supports DRM functions and may not be fully accessible [ 121.204445] ata1.00: configured for UDMA/133 [ 121.204454] ata1.00: device reported invalid CHS sector 0 [ 121.204541] sd 0:0:0:0: [sda] tag#18 UNKNOWN(0x2003) Result: hostbyte=0x00 driverbyte=0x08 [ 121.204546] sd 0:0:0:0: [sda] tag#18 Sense Key : 0x5 [current] [ 121.204550] sd 0:0:0:0: [sda] tag#18 ASC=0x21 ASCQ=0x4 [ 121.204555] sd 0:0:0:0: [sda] tag#18 CDB: opcode=0x93 93 08 00 00 00 00 00 04 28 80 00 00 00 30 00 00 [ 121.204559] print_req_error: I/O error, dev sda, sector 272512 After few reboots with these errors, and the SSD is corrupted. After blacklisting it, the errors are not seen and the SSD does not get corrupted any more. We know that M500IT MG02 and M500DC support this feature, Martin asked Micron for a list of SSDs which have support for this feature. But there was no reply. It is best to blacklst all Micron SSDs for now, except the known two variants, to prevent corrupting other Micron SSDs which do not support this.

[PATCH v5 3/7] phy: qcom-qusb2: Fix crash if nvmem cell not specified

[PATCH 0/2 linux-stable-4.4] ath10k: rebuild crypto header in rx data frames

by Sriram R

ath10k has a replay detection issue which was fixed in v4.14 and we would like to get this security fix also to linux-stable-4.4.But for that it depends on 3 mac80211 patches so the below mac80211 commits needs to be picked first in the same order and then apply this patchset. f980ebc058c2 : mac80211: allow not sending MIC up from driver for HW crypto f631a77ba920 : mac80211: allow same PN for AMSDU sub-frames cef0acd4d7d4 : mac80211: Add RX flag to indicate ICV stripped These patches should be applied in that order(commit f980ebc058c2 first) and they should apply cleanly with 3-way merge.

[PATCH] pmem: fix badblocks population for raw mode

by Toshi Kani

pmem_attach_disk() calls nvdimm_badblocks_populate() with resource range uninitialized in the case of raw mode. This leads the pmem driver to hit MCE despite of ARS reporting the range bad. Initialize 'bb_res' for raw mode.

[PATCH 7/7] tracepoint: Do not warn on ENOMEM

by Steven Rostedt

From: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com> Tracepoint should only warn when a kernel API user does not respect the required preconditions (e.g. same tracepoint enabled twice, or called to remove a tracepoint that does not exist). Silence warning in out-of-memory conditions, given that the error is returned to the caller. This ensures that out-of-memory error-injection testing does not trigger warnings in tracepoint.c, which were seen by syzbot.

[PATCH 1/7] tracing: Fix bad use of igrab in trace_uprobe.c

by Steven Rostedt

From: Song Liu <songliubraving(a)fb.com> As Miklos reported and suggested: This pattern repeats two times in trace_uprobe.c and in kernel/events/core.c as well: ret = kern_path(filename, LOOKUP_FOLLOW, &path); if (ret) goto fail_address_parse; inode = igrab(d_inode(path.dentry)); path_put(&path); And it's wrong. You can only hold a reference to the inode if you have an active ref to the superblock as well (which is normally through path.mnt) or holding s_umount. This way unmounting the containing filesystem while the tracepoint is active will give you the "VFS: Busy inodes after unmount..." message and a crash when the inode is finally put. Solution: store path instead of inode. This patch fixes two instances in trace_uprobe.c. struct path is added to struct trace_uprobe to keep the inode and containing mount point referenced.

Please apply 1572e45a924f ("perf/core: Fix the perf_cpu_time ...") to v4.9.y and older

by Guenter Roeck

Hi Greg, upstream commit 1572e45a924f ("perf/core: Fix the perf_cpu_time_max_percent check") fixes CVE-2017-18255. Please apply to v4.9.y and older. The patch applies cleanly to v4.9.y and v4.4.y; I didn't check older kernels. More recent kernels are not affected. Thanks, Guenter

I would advise not to include this patch in the previous stable trees. This patch does not fix any critical bug and for some very specific microbenchmarks on very large machines, it has shown performance regression. So, I don't think it is worth the risk. > From foo@baz Tue May 1 16:18:19 PDT 2018 > From: Shakeel Butt <shakeelb(a)google.com> > Date: Wed, 21 Feb 2018 14:45:28 -0800 > Subject: mm, mlock, vmscan: no more skipping pagevecs > From: Shakeel Butt <shakeelb(a)google.com> > [ Upstream commit 9c4e6b1a7027f102990c0395296015a812525f4d ] > When a thread mlocks an address space backed either by file pages which > are currently not present in memory or swapped out anon pages (not in > swapcache), a new page is allocated and added to the local pagevec > (lru_add_pvec), I/O is triggered and the thread then sleeps on the page. > On I/O completion, the thread can wake on a different CPU, the mlock > syscall will then sets the PageMlocked() bit of the page but will not be > able to put that page in unevictable LRU as the page is on the pagevec > of a different CPU.

[PATCH] ext4: fix bitmap position validation

by Lukas Czerner

Currently in ext4_valid_block_bitmap() we expect the bitmap to be positioned anywhere between 0 and s_blocksize clusters, but that's wrong because the bitmap can be placed anywhere in the block group. This causes false positives when validating bitmaps on perfectly valid file system layouts. Fix it by checking whether the bitmap is within the group boundary. The problem can be reproduced using the following mkfs -t ext3 -E stride=256 /dev/vdb1 mount /dev/vdb1 /mnt/test cd /mnt/test wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.16.3.tar.xz tar xf linux-4.16.3.tar.xz This will result in the warnings in the logs EXT4-fs error (device vdb1): ext4_validate_block_bitmap:399: comm tar: bg 84: block 2774529: invalid block bitmap Signed-off-by: Lukas Czerner <lczerner(a)redhat.com> Reported-by: Ilya Dryomov <idryomov(a)gmail.com> Fixes: 7dac4a1726a9 ("ext4: add validity checks for bitmap block numbers") Cc: stable(a)vger.kernel.org --- fs/ext4/balloc.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/fs/ext4/balloc.c b/fs/ext4/balloc.c index a33d8fb..0c0e383 100644 --- a/fs/ext4/balloc.c +++ b/fs/ext4/balloc.c @@ -338,7 +338,8 @@ static ext4_fsblk_t ext4_valid_block_bitmap(struct super_block *sb, /* check whether block bitmap block number is set */ blk = ext4_block_bitmap(sb, desc); offset = blk - group_first_block; - if (offset < 0 || EXT4_B2C(sbi, offset) >= sb->s_blocksize || + if (offset < 0 || + EXT4_B2C(sbi, offset) >= EXT4_CLUSTERS_PER_GROUP(sb) || !ext4_test_bit(EXT4_B2C(sbi, offset), bh->b_data)) /* bad block bitmap */ return blk; @@ -346,7 +347,8 @@ static ext4_fsblk_t ext4_valid_block_bitmap(struct super_block *sb, /* check whether the inode bitmap block number is set */ blk = ext4_inode_bitmap(sb, desc); offset = blk - group_first_block; - if (offset < 0 || EXT4_B2C(sbi, offset) >= sb->s_blocksize || + if (offset < 0 || + EXT4_B2C(sbi, offset) >= EXT4_CLUSTERS_PER_GROUP(sb) || !ext4_test_bit(EXT4_B2C(sbi, offset), bh->b_data)) /* bad block bitmap */ return blk; @@ -354,8 +356,8 @@ static ext4_fsblk_t ext4_valid_block_bitmap(struct super_block *sb, /* check whether the inode table block number is set */ blk = ext4_inode_table(sb, desc); offset = blk - group_first_block; - if (offset < 0 || EXT4_B2C(sbi, offset) >= sb->s_blocksize || - EXT4_B2C(sbi, offset + sbi->s_itb_per_group) >= sb->s_blocksize) + if (offset < 0 || EXT4_B2C(sbi, offset + sbi->s_itb_per_group) >= + EXT4_CLUSTERS_PER_GROUP(sb)) return blk; next_zero_bit = ext4_find_next_zero_bit(bh->b_data, EXT4_B2C(sbi, offset + sbi->s_itb_per_group), -- 2.7.5

+ mm-oom-fix-concurrent-munlock-and-oom-reaper-unmap.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, oom: fix concurrent munlock and oom reaper unmap, v3 has been added to the -mm tree. Its filename is mm-oom-fix-concurrent-munlock-and-oom-reaper-unmap.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-oom-fix-concurrent-munlock-and-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-oom-fix-concurrent-munlock-and-… 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: David Rientjes <rientjes(a)google.com> Subject: mm, oom: fix concurrent munlock and oom reaper unmap, v3 Since exit_mmap() is done without the protection of mm->mmap_sem, it is possible for the oom reaper to concurrently operate on an mm until MMF_OOM_SKIP is set. This allows munlock_vma_pages_all() to concurrently run while the oom reaper is operating on a vma. Since munlock_vma_pages_range() depends on clearing VM_LOCKED from vm_flags before actually doing the munlock to determine if any other vmas are locking the same memory, the check for VM_LOCKED in the oom reaper is racy. This is especially noticeable on architectures such as powerpc where clearing a huge pmd requires serialize_against_pte_lookup(). If the pmd is zapped by the oom reaper during follow_page_mask() after the check for pmd_none() is bypassed, this ends up deferencing a NULL ptl or a kernel oops. Fix this by manually freeing all possible memory from the mm before doing the munlock and then setting MMF_OOM_SKIP. The oom reaper can not run on the mm anymore so the munlock is safe to do in exit_mmap(). It also matches the logic that the oom reaper currently uses for determining when to set MMF_OOM_SKIP itself, so there's no new risk of excessive oom killing. This issue fixes CVE-2018-1000200.

[to-be-updated] mm-oom-fix-concurrent-munlock-and-oom-reaper-unmap.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, oom: fix concurrent munlock and oom reaper unmap has been removed from the -mm tree. Its filename was mm-oom-fix-concurrent-munlock-and-oom-reaper-unmap.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: David Rientjes <rientjes(a)google.com> Subject: mm, oom: fix concurrent munlock and oom reaper unmap Since exit_mmap() is done without the protection of mm->mmap_sem, it is possible for the oom reaper to concurrently operate on an mm until MMF_OOM_SKIP is set. This allows munlock_vma_pages_all() to concurrently run while the oom reaper is operating on a vma. Since munlock_vma_pages_range() depends on clearing VM_LOCKED from vm_flags before actually doing the munlock to determine if any other vmas are locking the same memory, the check for VM_LOCKED in the oom reaper is racy. This is especially noticeable on architectures such as powerpc where clearing a huge pmd requires serialize_against_pte_lookup(). If the pmd is zapped by the oom reaper during follow_page_mask() after the check for pmd_none() is bypassed, this ends up deferencing a NULL ptl. Fix this by reusing MMF_UNSTABLE to specify that an mm should not be reaped. This prevents the concurrent munlock_vma_pages_range() and unmap_page_range(). The oom reaper will simply not operate on an mm that has the bit set and leave the unmapping to exit_mmap().

Applied "ASoC: cirrus: i2s: Fix LRCLK configuration" to the asoc tree

by Mark Brown

The patch ASoC: cirrus: i2s: Fix LRCLK configuration has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

Applied "ASoC: cirrus: i2s: Fix {TX|RX}LinCtrlData setup" to the asoc tree

by Mark Brown

The patch ASoC: cirrus: i2s: Fix {TX|RX}LinCtrlData setup has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

The only currently used bit (Left_Right_Justify) has different position. Fix this and simplify the whole setup taking into account the fact that both registers have zero default value. The practical effect of the above is repaired SND_SOC_DAIFMT_RIGHT_J support (currently unused).

FAILED: patch "[PATCH] tpm: self test failure should not cause suspend to fail" 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 0803d7befa15cab5717d667a97a66214d2a4c083 Mon Sep 17 00:00:00 2001 From: Chris Chiu <chiu(a)endlessm.com> Date: Tue, 20 Mar 2018 15:36:40 +0800 Subject: [PATCH] tpm: self test failure should not cause suspend to fail The Acer Acer Veriton X4110G has a TPM device detected as: tpm_tis 00:0b: 1.2 TPM (device-id 0xFE, rev-id 71) After the first S3 suspend, the following error appears during resume: tpm tpm0: A TPM error(38) occurred continue selftest Any following S3 suspend attempts will now fail with this error: tpm tpm0: Error (38) sending savestate before suspend PM: Device 00:0b failed to suspend: error 38 Error 38 is TPM_ERR_INVALID_POSTINIT which means the TPM is not in the correct state. This indicates that the platform BIOS is not sending the usual TPM_Startup command during S3 resume. >From this point onwards, all TPM commands will fail. The same issue was previously reported on Foxconn 6150BK8MC and Sony Vaio TX3. The platform behaviour seems broken here, but we should not break suspend/resume because of this. When the unexpected TPM state is encountered, set a flag to skip the affected TPM_SaveState command on later suspends.

[PATCH 0/3] v4.16 tpmdd backports

If the machine has a large amount of memory (more than 64G), the size of a memory block can span multiple sections. By mistake, during hotremove we set only the first section to offline state. The bug was discovered because kernel selftest started to fail: https://lkml.kernel.org/r/20180423011247.GK5563@yexl-desktop After commit, "mm/memory_hotplug: optimize probe routine". But, the bug is older than this commit. In this optimization we also added a check for sections to be in a proper state during hotplug operation.

[PATCH] drm/vc4: Make sure vc4_bo_{inc, dec}_usecnt() calls are balanced

by Boris Brezillon

Commit b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl") introduced a mechanism to mark some BOs as purgeable to allow the driver to drop them under memory pressure. In order to implement this feature we had to add a mechanism to mark BOs as currently used by a piece of hardware which materialized through the ->usecnt counter. Plane code is supposed to increment usecnt when it attaches a BO to a plane and decrement it when it's done with this BO, which was done in the ->prepare_fb() and ->cleanup_fb() hooks. The problem is, async page flip logic does not go through the regular atomic update path, and ->prepare_fb() and ->cleanup_fb() are not called in this case. Fix that by manually calling vc4_bo_{inc,dec}_usecnt() in the async-page-flip path. Note that all this should go away as soon as we get generic async page flip support in the core, in the meantime, this fix should do the trick.

[PATCH 1/3] ioremap: Update pgtable free interfaces with addr

by Toshi Kani

From: Chintan Pandya <cpandya(a)codeaurora.org> This patch ("mm/vmalloc: Add interfaces to free unmapped page table") adds following 2 interfaces to free the page table in case we implement huge mapping. pud_free_pmd_page() and pmd_free_pte_page() Some architectures (like arm64) needs to do proper TLB maintanance after updating pagetable entry even in map. Why ? Read this, https://patchwork.kernel.org/patch/10134581/ Pass 'addr' in these interfaces so that proper TLB ops can be performed.

[PATCH for-next 0/6] IB/hfi1,rdmavt: Fixes for the 4.17 RC

by Dennis Dalessandro

Hi Jason and Doug, Here are 6 patches that might make the bar for RC. The first patch fixes something that came in pretty recently, I beleive 4.13. The second patch is trivial, but does modify user visible text. Patch 3 looks large but it's mostly comments. It just moves code. Patch 4 is also pretty simple. The last two patches fix memory leaks. If you don't think these pass muster for RC please carry over to for-next. --- Michael J. Ruhl (1): IB/hfi1 Use correct type for num_user_context Mike Marciniszyn (2): IB/hfi1: Fix handling of FECN marked multicast packet IB/hfi1: Fix loss of BECN with AHG Sebastian Sanchez (3): IB/hfi1: Fix NULL pointer dereference when invalid num_vls is used IB/{hfi1,rdmavt}: Fix memory leak in hfi1_alloc_devdata() upon failure IB/hfi1: Fix memory leak in exception path in get_irq_affinity() drivers/infiniband/hw/hfi1/affinity.c | 11 +++---- drivers/infiniband/hw/hfi1/driver.c | 19 ++++++++++--- drivers/infiniband/hw/hfi1/hfi.h | 8 +++-- drivers/infiniband/hw/hfi1/init.c | 43 ++++++++++++++++++++-------- drivers/infiniband/hw/hfi1/pcie.c | 3 -- drivers/infiniband/hw/hfi1/platform.c | 1 + drivers/infiniband/hw/hfi1/qsfp.c | 2 + drivers/infiniband/hw/hfi1/ruc.c | 50 ++++++++++++++++++++++++++------- drivers/infiniband/hw/hfi1/ud.c | 6 ++-- 9 files changed, 101 insertions(+), 42 deletions(-) -- -Denny
