[PATCH] drm/i915/gvt: Add missing vfio_unregister_group_dev() call

by Jason Gunthorpe

When converting to directly create the vfio_device the mdev driver has to put a vfio_register_emulated_iommu_dev() in the probe() and a pairing vfio_unregister_group_dev() in the remove. This was missed for gvt, add it.

[PATCH for-stable] efi: libstub: drop pointless get_memory_map() call

by Ard Biesheuvel

commit d80ca810f096ff66f451e7a3ed2f0cd9ef1ff519 upstream Currently, the non-x86 stub code calls get_memory_map() redundantly, given that the data it returns is never used anywhere. So drop the call.

[PATCH AUTOSEL 4.9 1/8] of/fdt: Don't calculate initrd size from DT if start > end

by Sasha Levin

From: Marek Bykowski <marek.bykowski(a)gmail.com> [ Upstream commit d5e3050c0feb8bf7b9a75482fafcc31b90257926 ] If the properties 'linux,initrd-start' and 'linux,initrd-end' of the chosen node populated from the bootloader, eg. U-Boot, are so that start > end, then the phys_initrd_size calculated from end - start is negative that subsequently gets converted to a high positive value for being unsigned long long. Then, the memory region with the (invalid) size is added to the bootmem and attempted being paged in paging_init() that results in the kernel fault. For example, on the FVP ARM64 system I'm running, the U-Boot populates the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0. The phys_initrd_size calculated is then ffff_ffff_7800_0000 (= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es as below. It should be stressed, it is generally a fault of the bootloader's with the kernel relying on it, however we should not allow the bootloader's misconfiguration to lead to the kernel oops. Not only the kernel should be bullet proof against it but also finding the root cause of the paging fault spanning over the bootloader, DT, and kernel may happen is not so easy.

[PATCH] usb: dwc3: gadget: Don't delay End Transfer on delayed_status

by Thinh Nguyen

The gadget driver may wait on the request completion when it sets the USB_GADGET_DELAYED_STATUS. Make sure that the End Transfer command can go through if the dwc->delayed_status is set so that the request can complete. When the delayed_status is set, the Setup packet is already processed, and the next phase should be either Data or Status. It's unlikely that the host would cancel the control transfer and send a new Setup packet during End Transfer command. But if that's the case, we can try again when ep0state returns to EP0_SETUP_PHASE.

[PATCH v4 3/6] usb: gadget: uvc: fix sg handling in error case

by Dan Vacura

If there is a transmission error the buffer will be returned too early, causing a memory fault as subsequent requests for that buffer are still queued up to be sent. Refactor the error handling to wait for the final request to come in before reporting back the buffer to userspace for all transfer types (bulk/isoc/isoc_sg). This ensures userspace knows if the frame was successfully sent.

That is reflected in rdt_init_res_defs_amd() by: r->cache.arch_has_empty_bitmaps = true; However given the unified code in cbm_validate(), checking for: val == 0 && !arch_has_empty_bitmaps is not enough because of another check in cbm_validate(): if ((zero_bit - first_bit) < r->cache.min_cbm_bits) The default value of r->cache.min_cbm_bits = 1. Leading to: $ cd /sys/fs/resctrl $ mkdir foo $ cd foo $ echo L3:0=0 > schemata -bash: echo: write error: Invalid argument $ cat /sys/fs/resctrl/info/last_cmd_status Need at least 1 bits in the mask Initialize the min_cbm_bits to 0 for AMD. Also, remove the default setting of min_cbm_bits and initialize it separately.

[PATCH 1/5] mmc: sdhci-of-arasan: Fix SDHCI_RESET_ALL for CQHCI

by Brian Norris

SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't tracking that properly in software. When out of sync, we may trigger various timeouts. It's not typical to perform resets while CQE is enabled, but one particular case I hit commonly enough: mmc_suspend() -> mmc_power_off(). Typically we will eventually deactivate CQE (cqhci_suspend() -> cqhci_deactivate()), but that's not guaranteed -- in particular, if we perform a partial (e.g., interrupted) system suspend. The same bug was already found and fixed for two other drivers, in v5.7 and v5.9: 5cf583f1fb9c mmc: sdhci-msm: Deactivate CQE during SDHC reset df57d73276b8 mmc: sdhci-pci: Fix SDHCI_RESET_ALL for CQHCI for Intel GLK-based controllers The latter is especially prescient, saying "other drivers using CQHCI might benefit from a similar change, if they also have CQHCI reset by SDHCI_RESET_ALL." So like these other patches, deactivate CQHCI when resetting the controller. Also, move around the DT/caps handling, because sdhci_setup_host() performs resets before we've initialized CQHCI. This is the pattern followed in other SDHCI/CQHCI drivers.

[PATCH v2] drm/mgag200: Fix PLL setup for G200_SE_A rev >=4

by Jocelyn Falempe

For G200_SE_A, PLL M setting is wrong, which leads to blank screen, or "signal out of range" on VGA display. previous code had "m |= 0x80" which was changed to m |= ((pixpllcn & BIT(8)) >> 1); Tested on G200_SE_A rev 42 This line of code was moved to another file with commit 85397f6bc4ff ("drm/mgag200: Initialize each model in separate function") but can be easily backported before this commit. v2: * put BIT(7) First to respect MSB-to-LSB (Thomas) * Add a comment to explain that this bit must be set (Thomas) Fixes: 2dd040946ecf ("drm/mgag200: Store values (not bits) in struct mgag200_pll_values") Cc: stable(a)vger.kernel.org Signed-off-by: Jocelyn Falempe <jfalempe(a)redhat.com> --- drivers/gpu/drm/mgag200/mgag200_g200se.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/mgag200/mgag200_g200se.c b/drivers/gpu/drm/mgag200/mgag200_g200se.c index be389ed91cbd..bd6e573c9a1a 100644 --- a/drivers/gpu/drm/mgag200/mgag200_g200se.c +++ b/drivers/gpu/drm/mgag200/mgag200_g200se.c @@ -284,7 +284,8 @@ static void mgag200_g200se_04_pixpllc_atomic_update(struct drm_crtc *crtc, pixpllcp = pixpllc->p - 1; pixpllcs = pixpllc->s; - xpixpllcm = pixpllcm | ((pixpllcn & BIT(8)) >> 1); + // For G200SE A, BIT(7) should be set unconditionally. + xpixpllcm = BIT(7) | pixpllcm; xpixpllcn = pixpllcn; xpixpllcp = (pixpllcs << 3) | pixpllcp; -- 2.37.3

[PATCH] counter: microchip-tcb-capture: Handle Signal1 read and Synapse

by William Breathitt Gray

The signal_read(), action_read(), and action_write() callbacks have been assuming Signal0 is requested without checking. This results in requests for Signal1 returning data for Signal0. This patch fixes these oversights by properly checking for the Signal's id in the respective callbacks and handling accordingly based on the particular Signal requested. The trig_inverted member of the mchp_tc_data is removed as superfluous.

[PATCH v2] mtd: parsers: bcm47xxpart: Fix halfblock reads

by Linus Walleij

There is some code in the parser that tries to read 0x8000 bytes into a block to "read in the middle" of the block. Well that only works if the block is also 0x10000 bytes all the time, else we get these parse errors as we reach the end of the flash: spi-nor spi0.0: mx25l1606e (2048 Kbytes) mtd_read error while parsing (offset: 0x200000): -22 mtd_read error while parsing (offset: 0x201000): -22 (...)

[PATCH 2/2] drm/connector: send hotplug uevent on connector cleanup

by Simon Ser

A typical DP-MST unplug removes a KMS connector. However care must be taken to properly synchronize with user-space. The expected sequence of events is the following: 1. The kernel notices that the DP-MST port is gone. 2. The kernel marks the connector as disconnected, then sends a uevent to make user-space re-scan the connector list. 3. User-space notices the connector goes from connected to disconnected, disables it. 4. Kernel handles the the IOCTL disabling the connector. On success, the very last reference to the struct drm_connector is dropped and drm_connector_cleanup() is called. 5. The connector is removed from the list, and a uevent is sent to tell user-space that the connector disappeared. The very last step was missing. As a result, user-space thought the connector still existed and could try to disable it again. Since the kernel no longer knows about the connector, that would end up with EINVAL and confused user-space. Fix this by sending a hotplug uevent from drm_connector_cleanup().

[tip: x86/urgent] x86/microcode/AMD: Apply the patch early on every logical thread

by tip-bot2 for Borislav Petkov

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: e7ad18d1169c62e6c78c01ff693fd362d9d65278 Gitweb: https://git.kernel.org/tip/e7ad18d1169c62e6c78c01ff693fd362d9d65278 Author: Borislav Petkov <bp(a)suse.de> AuthorDate: Wed, 05 Oct 2022 12:00:08 +02:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Tue, 18 Oct 2022 11:03:27 +02:00 x86/microcode/AMD: Apply the patch early on every logical thread Currently, the patch application logic checks whether the revision needs to be applied on each logical CPU (SMT thread). Therefore, on SMT designs where the microcode engine is shared between the two threads, the application happens only on one of them as that is enough to update the shared microcode engine. However, there are microcode patches which do per-thread modification, see Link tag below. Therefore, drop the revision check and try applying on each thread. This is what the BIOS does too so this method is very much tested. Btw, change only the early paths. On the late loading paths, there's no point in doing per-thread modification because if is it some case like in the bugzilla below - removing a CPUID flag - the kernel cannot go and un-use features it has detected are there early. For that, one should use early loading anyway.

Apply 0a6de78cff60 to 5.15+

by Nathan Chancellor

Hi Greg and Sasha, Please consider applying the following commits to 5.19 and 6.0: 4f001a21080f ("Kconfig.debug: simplify the dependency of DEBUG_INFO_DWARF4/5") bb1435f3f575 ("Kconfig.debug: add toolchain checks for DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT") 0a6de78cff60 ("lib/Kconfig.debug: Add check for non-constant .{s,u}leb128 support to DWARF5") The main change is the final one but the second patch is a prerequisite and a useful fix in its own right. The first change allows the second to apply cleanly and it is a good clean up as well. I have verified that they apply cleanly to those trees with 'patch -p1'. Attached is a manual backport for 5.15; the changes should not be necessary for older trees, as they do not have support for DWARF 5. If there are any problems or questions, please let me know. Cheers, Nathan

Please don't backport "fscrypt: stop using keyrings subsystem for fscrypt_master_key" to stable until it's ready

by Eric Biggers

Hi Sasha, Please stop backporting my commits to stable without asking, especially without Cc'ing to any mailing list that is archived on lore.kernel.org. "fscrypt: stop using keyrings subsystem for fscrypt_master_key" is a big change, and there's already a fix for it pending (https://lore.kernel.org/r/20221011213838.209879-1-ebiggers@kernel.org). I've been planning on doing the backports myself once the change has had a bit more time to soak, which is why I intentionally didn't add Cc stable. It appears you also backported several other commits just to get it apply cleanly to 5.10, so please drop those too for now. - Eric

[PATCH] drm/amdgpu: Remove ATC L2 access for MMHUB 2.1.x

by Lijo Lazar

MMHUB 2.1.x versions don't have ATCL2. Remove accesses to ATCL2 registers.

[PATCH] usb: gadget: uvc: fix dropped frame after missed isoc

by Dan Vacura

With the re-use of the previous completion status in 0d1c407b1a749 ("usb: dwc3: gadget: Return proper request status") it could be possible that the next frame would also get dropped if the current frame has a missed isoc error.

[PATCH AUTOSEL 4.14 1/8] of/fdt: Don't calculate initrd size from DT if start > end

by Sasha Levin

From: Marek Bykowski <marek.bykowski(a)gmail.com> [ Upstream commit d5e3050c0feb8bf7b9a75482fafcc31b90257926 ] If the properties 'linux,initrd-start' and 'linux,initrd-end' of the chosen node populated from the bootloader, eg. U-Boot, are so that start > end, then the phys_initrd_size calculated from end - start is negative that subsequently gets converted to a high positive value for being unsigned long long. Then, the memory region with the (invalid) size is added to the bootmem and attempted being paged in paging_init() that results in the kernel fault. For example, on the FVP ARM64 system I'm running, the U-Boot populates the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0. The phys_initrd_size calculated is then ffff_ffff_7800_0000 (= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es as below. It should be stressed, it is generally a fault of the bootloader's with the kernel relying on it, however we should not allow the bootloader's misconfiguration to lead to the kernel oops. Not only the kernel should be bullet proof against it but also finding the root cause of the paging fault spanning over the bootloader, DT, and kernel may happen is not so easy.

So even though we clear inode i_nlink before iput in error handling, it still won't wipe inode since we'll refresh inode from dinode during inode lock. So just like clear inode i_nlink, we clear ocfs2 i_links_count as well. Also do the same change for ocfs2_symlink().

But this introduce a race, the freed bit may be reused immediately by another thread, which will update dinode, e.g. i_generation. Then iput this inode will lead to BUG: inode->i_generation != le32_to_cpu(fe->i_generation) We could make this inode as bad, but we did want to do operations like wipe in some cases. Since the claimed inode bit can only affect that an dinode is missing and will return back after fsck, it seems not a big problem. So just leave it as is by revert the reclaim logic.

[PATCH v3 3/6] usb: gadget: uvc: fix sg handling in error case

by Dan Vacura

If there is a transmission error the buffer will be returned too early, causing a memory fault as subsequent requests for that buffer are still queued up to be sent.

Current code gets package ID by shifting out all the APIC-ID bits that Linux supports, rather than shifting out all the APIC-ID bits that CPUID.1F enumerates. This introduces problems when CPUID.1F enumerates a level that Linux does not support. For example, on a single package AlderLake-N, there are 2 Ecore Modules with 4 atom cores in each module. Linux does not support the Module level and interprets the Module ID bits as package ID and erroneously reports a multi module system as a multi-package system. Fix this by using APIC-ID bits above all the CPUID.1F enumerated levels as package ID.

But an AlderLake-N platform adds a Module level between core and package, Linux excludes the unknown modules bits from the core ID, resulting in duplicate core ID's. To keep core ID unique within a package, Linux must include all APIC-ID bits for known or unknown levels above the core and below the package in the core ID. It is important to understand that core ID's have always come directly from the APIC-ID encoding, which comes from the BIOS. Thus there is no guarantee that they start at 0, or that they are contiguous. As such, naively using them for array indexes can be problematic.

Lack of CONFIG_EFI_STUB can prevent kernels from booting via EFI in certain circumstances. This check was added by 8f24f8c2fc82 ("efi/libstub: Annotate firmware routines as __efiapi") to ensure that __attribute__((ms_abi)) was available, as -mabi=ms is not actually used in any cflags. According to the GCC documentation, this attribute has been supported since GCC 4.4.7. The kernel currently requires GCC 5.1 so this check is not necessary; even when that change landed in 5.6, the kernel required GCC 4.9 so it was unnecessary then as well. Clang supports __attribute__((ms_abi)) for all versions that are supported for building the kernel so no additional check is needed. Remove the 'depends on' line altogether to allow CONFIG_EFI_STUB to be selected when CONFIG_EFI is enabled, regardless of compiler.

[PATCH] x86/Kconfig: Drop check for '-mabi=ms' for CONFIG_EFI_STUB

by Nathan Chancellor

A recent change in LLVM made CONFIG_EFI_STUB unselectable because it no longer pretends to support '-mabi=ms', breaking the dependency in Kconfig. Lack of CONFIG_EFI_STUB can prevent kernels from booting via EFI in certain circumstances. This check was added by commit 8f24f8c2fc82 ("efi/libstub: Annotate firmware routines as __efiapi") to ensure that '__attribute__((ms_abi))' was available, as '-mabi=ms' is not actually used in any cflags. According to the GCC documentation, this attribute has been supported since GCC 4.4.7. The kernel currently requires GCC 5.1 so this check is not necessary; even when that change landed in 5.6, the kernel required GCC 4.9 so it was unnecessary then as well. Clang supports '__attribute__((ms_abi))' for all versions that are supported for building the kernel so no additional check is needed. Remove the 'depends on' line altogether to allow CONFIG_EFI_STUB to be selected when CONFIG_EFI is enabled, regardless of compiler.

[PATCH AUTOSEL 4.9 01/10] media: cx88: Fix a null-ptr-deref bug in buffer_prepare()

[PATCH stable 5.10] mm: hugetlb: fix UAF in hugetlb_handle_userfault

by Liu Shixin

commit 958f32ce832ba781ac20e11bb2d12a9352ea28fc upstream.

[PATCH stable-5.4 1/1] io_uring/af_unix: defer registered files gc to io_uring release

by Pavel Begunkov

[ upstream commit 0091bfc81741b8d3aeb3b7ab8636f911b2de6e80 ] Instead of putting io_uring's registered files in unix_gc() we want it to be done by io_uring itself. The trick here is to consider io_uring registered files for cycle detection but not actually putting them down. Because io_uring can't register other ring instances, this will remove all refs to the ring file triggering the ->release path and clean up with io_ring_ctx_free().

We should not allow any write into a fs with unsupported RO flags. - Still try to search block group items In fact, behavior/on-disk format change to extent tree should not need a full incompat flag. And since we can ensure fs with unsupported RO flags never got any writes (with above case fixed), then we can even skip block group items search at mount time. This patch will enhance the unsupported RO compat flags by: - Reject read-write remount if there are unsupported RO compat flags - Go dummy block group items directly for unsupported RO compat flags In fact, only changes to chunk/subvolume/root/csum trees should go incompat flags. The latter part should allow future change to extent tree to be compat RO flags. Thus this patch also needs to be backported to all stable trees.

[PATCH stable 5.15] mm: hugetlb: fix UAF in hugetlb_handle_userfault

by Liu Shixin

commit 958f32ce832ba781ac20e11bb2d12a9352ea28fc upstream.

[PATCH 5.10 0/2] Stable 5.10 backport of RS485 initial polarity fix

by Dominique Martinet

This is the backport of the RS485 polarity fixes discussed here: https://lkml.kernel.org/r/20221010085305.GA32599@wunner.de It fixes RS485 DE initially set wrong on driver init, blocking other devices from transmitting on the bus. Mizobuchi-san did the backport and tested on our imx-based platform, but we do not have any hardware to test other drivers. The commits also apply cleanly on 5.15, and for 5.19 the second commit does (first one has already been picked up), but these have not been tested so would require more checking. Kernels older than 5.10 do not have this particular polarity inversion problem and do not need this as far as I can see. (there might be other problems this addresses that I am not aware of though) Thanks, Lino Sanfilippo (1): serial: core: move RS485 configuration tasks from drivers into core Lukas Wunner (1): serial: Deassert Transmit Enable on probe in driver-specific way drivers/tty/serial/8250/8250_omap.c | 3 ++ drivers/tty/serial/8250/8250_pci.c | 9 +---- drivers/tty/serial/8250/8250_port.c | 12 +++--- drivers/tty/serial/fsl_lpuart.c | 7 ++-- drivers/tty/serial/imx.c | 8 +--- drivers/tty/serial/serial_core.c | 61 +++++++++++++++++++++++------ 6 files changed, 65 insertions(+), 35 deletions(-) -- 2.35.1

[to-be-updated] ocfs2-fix-ocfs2-corrupt-when-iputting-an-inode.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: ocfs2: fix ocfs2 corrupt when iputting an inode has been removed from the -mm tree. Its filename was ocfs2-fix-ocfs2-corrupt-when-iputting-an-inode.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: Wangyan <wangyan122(a)huawei.com> Subject: ocfs2: fix ocfs2 corrupt when iputting an inode In this condition, it will cause an bug on error. ocfs2_mkdir() ->ocfs2_mknod() ->ocfs2_mknod_locked() ->__ocfs2_mknod_locked() //Assume inode->i_generation is genN. ->inode->i_generation = osb->s_next_generation++; // The inode lockres has been initialized. ->ocfs2_populate_inode() ->ocfs2_create_new_inode_locks() ->An error happened, returned value is non-zero // free the start_bit x in bg_blkno ->ocfs2_free_suballoc_bits() ->... /* Another process execute mkdir success in this place, and it occupied the start_bit x in bg_blkno which has been freed before.

[RFC v5.10 0/3] mac80211 use-after-free fix

by Johannes Berg

Hi, So I looked at this, and it wasn't great one way or the other... The first patch here is obvious, let's just take it and get one of the parsings out of the way. The second one removes a couple of more cases where this is done, since it only happens when the last argument is non-NULL. The third then is to avoid the UAF, and is simpler now since only a few places can even allocate it. johannes

Possible dependencies: c0a581d7126c ("tracing: Disable interrupt or preemption before acquiring arch_spinlock_t") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From c0a581d7126c0bbc96163276f585fd7b4e4d8d0e Mon Sep 17 00:00:00 2001 From: Waiman Long <longman(a)redhat.com> Date: Thu, 22 Sep 2022 10:56:22 -0400 Subject: [PATCH] tracing: Disable interrupt or preemption before acquiring arch_spinlock_t It was found that some tracing functions in kernel/trace/trace.c acquire an arch_spinlock_t with preemption and irqs enabled. An example is the tracing_saved_cmdlines_size_read() function which intermittently causes a "BUG: using smp_processor_id() in preemptible" warning when the LTP read_all_proc test is run. That can be problematic in case preemption happens after acquiring the lock. Add the necessary preemption or interrupt disabling code in the appropriate places before acquiring an arch_spinlock_t. The convention here is to disable preemption for trace_cmdline_lock and interupt for max_lock.

[PATCH 01/10] staging: r8188eu: fix led register settings

by Martin Kaiser

Using an InterTech DMG-02 dongle, the led remains on when the system goes into standby mode. After wakeup, it's no longer possible to control the led. It turned out that the register settings to enable or disable the led were not correct. They worked for some dongles like the Edimax V2 but not for others like the InterTech DMG-02. This patch fixes the register settings. Bit 3 in the led_cfg2 register controls the led status, bit 5 must always be set to be able to control the led, bit 6 has no influence on the led. Setting the mac_pinmux_cfg register is not necessary. These settings were tested with Edimax V2 and InterTech DMG-02.

The downside is that by replacing the onion unwind along the error paths, the ppgtt cleanup must handle a partially constructed vm. This includes ensuring that the vm->cleanup is set prior to the error path.

For the emulator's two calls to exception_type(), treat the #DB as fault-like, as the emulator handles only code breakpoint and general detect #DBs, both of which are fault-like. For event injection, which uses exception_type() to determine whether to set EFLAGS.RF=1 on the stack, keep the current behavior of not setting RF=1 for #DBs. Intel and AMD explicitly state RF isn't set on code #DBs, so exempting by failing the "== EXCPT_FAULT" check is correct. The only other fault-like #DB is General Detect, and despite Intel and AMD both strongly implying (through omission) that General Detect #DBs should set RF=1, hardware (multiple generations of both Intel and AMD), in fact does not. Through insider knowledge, extreme foresight, sheer dumb luck, or some combination thereof, KVM correctly handled RF for General Detect #DBs.

As a side effect, the watchdog would never be cancelled and its function would be called at an inappropriate time. This was observed while running Fluster with GStreamer as a backend. Some programming error would cause the decoder IRQ to be call very quickly after the trigger. Later calls into the driver would deadlock due to the unbalanced state.

The problem is that the synthetic event field "char file[]" will read the value given to it as a string without any memory checks to make sure the address is valid. The above example will pass in the user space address and the sythetic event code will happily call strlen() on it and then strscpy() where either one will cause an oops when accessing user space addresses. Use the helper functions from trace_kprobe and trace_eprobe that can read strings safely (and actually succeed when the address is from user space and the memory is mapped in).

The ftrace_boot_snapshot in particular requires the snapshot to be allocated because it will take a snapshot at the end of boot up allowing to see the traces that happened during boot so that it's not lost when user space takes over. When a tracer is registered (started) there's a path that checks if it requires the snapshot buffer or not, and if it does not and it was allocated it will do a synchronization and free the snapshot buffer. This is only required if the previous tracer was using it for "max latency" snapshots, as it needs to make sure all max snapshots are complete before freeing. But this is only needed if the previous tracer was using the snapshot buffer for latency (like irqoff tracer and friends). But it does not make sense to free it, if the previous tracer was not using it, and the snapshot was allocated by the cmdline parameters. This basically takes away the point of allocating it in the first place! Note, the allocated snapshot worked fine for just trace events, but fails when a tracer is enabled on the cmdline. Further investigation, this goes back even further and it does not require a tracer on the cmdline to fail. Simply enable snapshots and then enable a tracer, and it will remove the snapshot.

The ftrace_boot_snapshot in particular requires the snapshot to be allocated because it will take a snapshot at the end of boot up allowing to see the traces that happened during boot so that it's not lost when user space takes over. When a tracer is registered (started) there's a path that checks if it requires the snapshot buffer or not, and if it does not and it was allocated it will do a synchronization and free the snapshot buffer. This is only required if the previous tracer was using it for "max latency" snapshots, as it needs to make sure all max snapshots are complete before freeing. But this is only needed if the previous tracer was using the snapshot buffer for latency (like irqoff tracer and friends). But it does not make sense to free it, if the previous tracer was not using it, and the snapshot was allocated by the cmdline parameters. This basically takes away the point of allocating it in the first place! Note, the allocated snapshot worked fine for just trace events, but fails when a tracer is enabled on the cmdline. Further investigation, this goes back even further and it does not require a tracer on the cmdline to fail. Simply enable snapshots and then enable a tracer, and it will remove the snapshot.

[PATCH AUTOSEL 5.19 01/63] staging: r8188eu: do not spam the kernel log

From: Michael Straube <straube.linux(a)gmail.com> [ Upstream commit 9a4d0d1c21b974454926c3b832b4728679d818eb ] Drivers should not spam the kernel log if they work properly.

[PATCH AUTOSEL 4.14 1/6] drm: Use size_t type for len variable in drm_copy_field()

by Sasha Levin

From: Javier Martinez Canillas <javierm(a)redhat.com> [ Upstream commit 94dc3471d1b2b58b3728558d0e3f264e9ce6ff59 ] The strlen() function returns a size_t which is an unsigned int on 32-bit arches and an unsigned long on 64-bit arches. But in the drm_copy_field() function, the strlen() return value is assigned to an 'int len' variable. Later, the len variable is passed as copy_from_user() third argument that is an unsigned long parameter as well. In theory, this can lead to an integer overflow via type conversion. Since the assignment happens to a signed int lvalue instead of a size_t lvalue. In practice though, that's unlikely since the values copied are set by DRM drivers and not controlled by userspace. But using a size_t for len is the correct thing to do anyways.

[PATCH AUTOSEL 6.0 01/46] arm64: dts: qcom: sdm845: narrow LLCC address space

by Sasha Levin

From: Krzysztof Kozlowski <krzysztof.kozlowski(a)linaro.org> [ Upstream commit 300b5f661eebefb8571841b78091343eb87eca54 ] The Last Level Cache Controller (LLCC) device does not need to access entire LLCC address space. Currently driver uses only hardware info and status registers which both reside in LLCC0_COMMON range (offset 0x30000, size 0x1000). Narrow the address space to allow binding other drivers to rest of LLCC address space.

[PATCH AUTOSEL 5.15 01/47] clk: zynqmp: Fix stack-out-of-bounds in strncpy`

by Sasha Levin

From: Ian Nam <young.kwan.nam(a)xilinx.com> [ Upstream commit dd80fb2dbf1cd8751efbe4e53e54056f56a9b115 ] "BUG: KASAN: stack-out-of-bounds in strncpy+0x30/0x68" Linux-ATF interface is using 16 bytes of SMC payload. In case clock name is longer than 15 bytes, string terminated NULL character will not be received by Linux. Add explicit NULL character at last byte to fix issues when clock name is longer.

This is less than ideal as it can cause unnecessary cache invalidations with NFSv4 and unnecessary remeasurements for IMA. The increment in ext4_mark_iloc_dirty is also problematic since it can corrupt the i_version counter for ea_inodes. We aren't bumping the file times in ext4_mark_iloc_dirty, so changing the i_version there seems wrong, and is the cause of both problems.

Because of this, it was gated behind a mount option (implemented via the MS_I_VERSION mountoption flag). Commit ae5e165d855d (fs: new API for handling inode->i_version) made the i_version flag much less expensive, so there is no longer a performance penalty from enabling it. xfs and btrfs already enable it unconditionally when the on-disk format can support it.

Because of this, it was gated behind a mount option (implemented via the MS_I_VERSION mountoption flag). Commit ae5e165d855d (fs: new API for handling inode->i_version) made the i_version flag much less expensive, so there is no longer a performance penalty from enabling it. xfs and btrfs already enable it unconditionally when the on-disk format can support it. Have ext4 ignore the SB_I_VERSION flag, and just enable it unconditionally. While we're in here, mark the i_version mount option Opt_removed.

Backport of 607e57c6c62c009 for 5.10 and 5.15

by Nathan Chancellor

Hi Greg and Sasha, Please find attached backports for commit 607e57c6c62c ("hardening: Remove Clang's enable flag for -ftrivial-auto-var-init=zero") along with prerequisite changes for 5.10 and 5.15. This change is necessary to keep CONFIG_INIT_STACK_ALL_ZERO working with clang-16. This change is already queued up for 5.19 and newer and it is not relevant for 5.4 and older (at least upstream, I'll be doing backports for older Android branches shortly). If there are any questions or problems, please let me know! Cheers, Nathan

[PATCH 4.14 0/2] nilfs2 lockdep warning fixes

by Ryusuke Konishi

Hi Greg, please apply the following two cc-stable patches to 4.14-stable. Ryusuke Konishi (2): nilfs2: fix lockdep warnings in page operations for btree nodes nilfs2: fix lockdep warnings during disk space reclamation During testing nilfs2 filesystem with stable trees, I encountered a lockdep warning followed by a kernel panic (by panic_on_warn) only in 4.14-stable. I found that the cause was the lack of these patches which are applied to other newer stable trees. I guess they were dropped since the first patch was not applicable as is due to a pagevec change. After I manually applied them to 4.14, the panic and lockdep warning have gone. So, I believe these should be backported to 4.14-stable as well.

[PATCH 4.19] riscv: fix build with binutils 2.38

by Conor Dooley

From: Aurelien Jarno <aurelien(a)aurel32.net> commit 6df2a016c0c8a3d0933ef33dd192ea6606b115e3 upstream. From version 2.38, binutils default to ISA spec version 20191213. This means that the csr read/write (csrr*/csrw*) instructions and fence.i instruction has separated from the `I` extension, become two standalone extensions: Zicsr and Zifencei. As the kernel uses those instruction, this causes the following build failure: CC arch/riscv/kernel/vdso/vgettimeofday.o <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h: Assembler messages: <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' <<BUILDDIR>>/arch/riscv/include/asm/vdso/gettimeofday.h:71: Error: unrecognized opcode `csrr a5,0xc01' The fix is to specify those extensions explicitly in -march. However as older binutils version do not support this, we first need to detect that.

Possible dependencies: cef7820d6abf ("btrfs: fix missed extent on fsync after dropping extent maps") thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From cef7820d6abf8d61f8e1db411eae3c712f6d72a2 Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Mon, 19 Sep 2022 15:06:28 +0100 Subject: [PATCH] btrfs: fix missed extent on fsync after dropping extent maps When dropping extent maps for a range, through btrfs_drop_extent_cache(), if we find an extent map that starts before our target range and/or ends before the target range, and we are not able to allocate extent maps for splitting that extent map, then we don't fail and simply remove the entire extent map from the inode's extent map tree. This is generally fine, because in case anyone needs to access the extent map, it can just load it again later from the respective file extent item(s) in the subvolume btree. However, if that extent map is new and is in the list of modified extents, then a fast fsync will miss the parts of the extent that were outside our range (that needed to be split), therefore not logging them. Fix that by marking the inode for a full fsync. This issue was introduced after removing BUG_ON()s triggered when the split extent map allocations failed, done by commit 7014cdb49305ed ("Btrfs: btrfs_drop_extent_cache should never fail"), back in 2012, and the fast fsync path already existed but was very recent. Also, in the case where we could allocate extent maps for the split operations but then fail to add a split extent map to the tree, mark the inode for a full fsync as well. This is not supposed to ever fail, and we assert that, but in case assertions are disabled (CONFIG_BTRFS_ASSERT is not set), it's the correct thing to do to make sure a fast fsync will not miss a new extent.

We should not allow any write into a fs with unsupported RO flags. - Still try to search block group items In fact, behavior/on-disk format change to extent tree should not need a full incompat flag. And since we can ensure fs with unsupported RO flags never got any writes (with above case fixed), then we can even skip block group items search at mount time. This patch will enhance the unsupported RO compat flags by: - Reject read-write remount if there are unsupported RO compat flags - Go dummy block group items directly for unsupported RO compat flags In fact, only changes to chunk/subvolume/root/csum trees should go incompat flags. The latter part should allow future change to extent tree to be compat RO flags. Thus this patch also needs to be backported to all stable trees.

This patch will enhance the unsupported RO compat flags by: - Reject read-write remount if there are unsupported RO compat flags - Go dummy block group items directly for unsupported RO compat flags In fact, only changes to chunk/subvolume/root/csum trees should go incompat flags.

And if iterate_dir() return -EIO, which mean directory entry is corrupted, return STATUS_FILE_CORRUPT_ERROR error response.
