[PATCH] binder: check offset alignment in binder_get_object()

by Carlos Llamas

Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying txn") introduced changes to how binder objects are copied. In doing so, it unintentionally removed an offset alignment check done through calls to binder_alloc_copy_from_buffer() -> check_buffer(). These calls were replaced in binder_get_object() with copy_from_user(), so now an explicit offset alignment check is needed here. This avoids later complications when unwinding the objects gets harder. It is worth noting this check existed prior to commit 7a67a39320df ("binder: add function to copy binder object from buffer"), likely removed due to redundancy at the time.

He can resend if that helps with the process) Peng Fan also gave his reviewed-by in the v2 thread, it's always appreciable to get an ack from someone closer to the authors. Since the code itself is identical, I'll leave the decision to update or not up to you; I just can't unsee the "failue" in the summary :) Thanks! -- Dominique

v5.15+ backport request

by dcrady＠os.amperecomputing.com

Please backport the following v6.7 commit: commit be097997a273 ("KVM: arm64: Always invalidate TLB for stage-2 permission faults") to stable kernels v5.15 and newer to fix: It is possible for multiple vCPUs to fault on the same IPA and attempt to resolve the fault. One of the page table walks will actually update the PTE and the rest will return -EAGAIN per our race detection scheme. KVM elides the TLB invalidation on the racing threads as the return value is nonzero. Before commit a12ab1378a88 ("KVM: arm64: Use local TLBI on permission relaxation") KVM always used broadcast TLB invalidations when handling permission faults, which had the convenient property of making the stage-2 updates visible to all CPUs in the system. However now we do a local invalidation, and TLBI elision leads to the vCPU thread faulting again on the stale entry. Remember that the architecture permits the TLB to cache translations that precipitate a permission fault. Invalidate the TLB entry responsible for the permission fault if the stage-2 descriptor has been relaxed, regardless of which thread actually did the job. Thank you! doug rady

I'm not sure if you've missed this patch in mail box. :) The patch is pretty important as it lets the device tree (dts) decide whether to enable U3PHY or PCIe PHY. Because this is a shared hardware phy and could only be configured in dts to decide which function to be initialized, so it's something that should be included in the board-specific dts files. Do you think it needs to be resubmitted, or is it still in the queue for review? It's meant to be ready for action from kernel version 6.8 onwards. Looking forward to your thoughts on this. Let me know if there's anything else you need from my side. > Prior to this fix, the system would exhibit the following probe failure messages > for xhci1: > xhci-mtk 11290000.usb: supply vbus not found, using dummy regulator > xhci-mtk 11290000.usb: uwk - reg:0x400, version:104 > xhci-mtk 11290000.usb: xHCI Host Controller > xhci-mtk 11290000.usb: new USB bus registered, assigned bus number 5 > xhci-mtk 11290000.usb: clocks are not stable (0x1003d0f) > xhci-mtk 11290000.usb: can't setup: -110 > xhci-mtk 11290000.usb: USB bus 5 deregistered > xhci-mtk: probe of 11290000.usb failed with error -110 > > With the application of this dts fixup, the aforementioned initialization errors > are resolved and xhci1 is working. > > Signed-off-by: Macpaul Lin <macpaul.lin(a)mediatek.com> > --- > arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts b/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts > index 7fc515a07c65..e0b9f2615c11 100644 > --- a/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts > +++ b/arch/arm64/boot/dts/mediatek/mt8395-genio-1200-evk.dts > @@ -854,6 +854,10 @@ > > &u3phy1 { > status = "okay"; > + > + u3port1: usb-phy@700 { > + mediatek,force-mode; > + }; > }; > > &u3phy2 { > @@ -885,6 +889,8 @@ > }; > > &xhci1 { > + phys = <&u2port1 PHY_TYPE_USB2>, > + <&u3port1 PHY_TYPE_USB3>; > vusb33-supply = <&mt6359_vusb_ldo_reg>; > status = "okay"; > }; Thanks Macpaul Lin

[PATCH v2 2/2] wifi: rtl8xxxu: enable MFP support with security flag of RX descriptor

by Martin Kaistra

In order to connect to networks which require 802.11w, add the MFP_CAPABLE flag and let mac80211 do the actual crypto in software.

[PATCH 2/2] wifi: rtl8xxxu: enable MFP support

In order to connect to networks which require 802.11w, add the MFP_CAPABLE flag and let mac80211 do the actual crypto in software.

[PATCH v2 0/2] usb: dwc3: Disable susphy during initialization

by Thinh Nguyen

We notice some platforms set "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when they should not need to. Just make sure that the GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY are clear during initialization. The host initialization involved xhci. So the dwc3 needs to implement the xhci_plat_priv->plat_start() for xhci to re-enable the suspend bits. Since there's a prerequisite patch to drivers/usb/host/xhci-plat.h that's not a fix patch, this series should go on Greg's usb-testing branch instead of usb-linus.

Mike has a fix in that path for resv uncharge but it looks like the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd() will update the cgroup pointer, so it requires to be called with the lock held.

[PATCH] drm/xe/vm: prevent UAF in rebind_work_func()

by Matthew Auld

We flush the rebind worker during the vm close phase, however in places like preempt_fence_work_func() we seem to queue the rebind worker without first checking if the vm has already been closed. The concern here is the vm being closed with the worker flushed, but then being rearmed later, which looks like potential uaf, since there is no actual refcounting to track the queued worker. To ensure this can't happen prevent queueing the rebind worker once the vm has been closed.

[PATCH v2] PCI: dw-rockchip: Fix GPIO initialization flag

by Niklas Cassel

PERST is active low according to the PCIe specification. However, the existing pcie-dw-rockchip.c driver does: gpiod_set_value(..., 0); msleep(100); gpiod_set_value(..., 1); When asserting + deasserting PERST. This is of course wrong, but because all the device trees for this compatible string have also incorrectly marked this GPIO as ACTIVE_HIGH: $ git grep -B 10 reset-gpios arch/arm64/boot/dts/rockchip/rk3568* $ git grep -B 10 reset-gpios arch/arm64/boot/dts/rockchip/rk3588* The actual toggling of PERST is correct. (And we cannot change it anyway, since that would break device tree compatibility.) However, this driver does request the GPIO to be initialized as GPIOD_OUT_HIGH, which does cause a silly sequence where PERST gets toggled back and forth for no good reason. Fix this by requesting the GPIO to be initialized as GPIOD_OUT_LOW (which for this driver means PERST asserted). This will avoid an unnecessary signal change where PERST gets deasserted (by devm_gpiod_get_optional()) and then gets asserted (by rockchip_pcie_start_link()) just a few instructions later. Before patch, debug prints on EP side, when booting RC: [ 845.606810] pci: PERST asserted by host! [ 852.483985] pci: PERST de-asserted by host! [ 852.503041] pci: PERST asserted by host!

[PATCH v1] arm64: dts: imx8mm: fix missing pgc_vpu_* power domain parent

by Vitor Soares

[PATCH] random: handle creditable entropy from atomic process context

by Jason A. Donenfeld

The entropy accounting changes a static key when the RNG has initialized, since it only ever initializes once. Static key changes, however, cannot be made from atomic context, so depending on where the last creditable entropy comes from, the static key change might need to be deferred to a worker. Previously the code used the execute_in_process_context() helper function, which accounts for whether or not the caller is in_interrupt(). However, that doesn't account for the case where the caller is actually in process context but is holding a spinlock. This turned out to be the case with input_handle_event() in drivers/input/input.c contributing entropy: [<ffffffd613025ba0>] die+0xa8/0x2fc [<ffffffd613027428>] bug_handler+0x44/0xec [<ffffffd613016964>] brk_handler+0x90/0x144 [<ffffffd613041e58>] do_debug_exception+0xa0/0x148 [<ffffffd61400c208>] el1_dbg+0x60/0x7c [<ffffffd61400c000>] el1h_64_sync_handler+0x38/0x90 [<ffffffd613011294>] el1h_64_sync+0x64/0x6c [<ffffffd613102d88>] __might_resched+0x1fc/0x2e8 [<ffffffd613102b54>] __might_sleep+0x44/0x7c [<ffffffd6130b6eac>] cpus_read_lock+0x1c/0xec [<ffffffd6132c2820>] static_key_enable+0x14/0x38 [<ffffffd61400ac08>] crng_set_ready+0x14/0x28 [<ffffffd6130df4dc>] execute_in_process_context+0xb8/0xf8 [<ffffffd61400ab30>] _credit_init_bits+0x118/0x1dc [<ffffffd6138580c8>] add_timer_randomness+0x264/0x270 [<ffffffd613857e54>] add_input_randomness+0x38/0x48 [<ffffffd613a80f94>] input_handle_event+0x2b8/0x490 [<ffffffd613a81310>] input_event+0x6c/0x98 According to Guoyong, it's not really possible to refactor the various drivers to never hold a spinlock there. And in_atomic() isn't reliable. So, rather than trying to be too fancy, just punt the change in the static key to a workqueue always. There's basically no drawback of doing this, as the code already needed to account for the static key not changing immediately, and given that it's just an optimization, there's not exactly a hurry to change the static key right away, so deferal is fine.

[PATCH 2/2] serial: stm32: Reset .throttled state in .startup()

by Uwe Kleine-König

When an UART is opened that still has .throttled set from a previous open, the RX interrupt is enabled but the irq handler doesn't consider it. This easily results in a stuck irq with the effect to occupy the CPU in a tight loop. So reset the throttle state in .startup() to ensure that RX irqs are handled.

[PATCH 1/2] serial: stm32: Return IRQ_NONE in the ISR if no handling happend

by Uwe Kleine-König

If there is a stuck irq that the handler doesn't address, returning IRQ_HANDLED unconditionally makes it impossible for the irq core to detect the problem and disable the irq. So only return IRQ_HANDLED if an event was handled. A stuck irq is still problematic, but with this change at least it only makes the UART nonfunctional instead of occupying the (usually only) CPU by 100% and so stall the whole machine.

[PATCH] net: usb: ax88179_178a: avoid writing the mac address before first reading

by Jose Ignacio Tornos Martinez

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets"), reset operation, in which the default mac address from the device is read, is not executed from bind operation and the random address, that is pregenerated just in case, is direclty written the first time in the device, so the default one from the device is not even read. This writing is not dangerous because is volatile and the default mac address is not missed. In order to avoid this, do not allow writing a mac address directly into the device, if the default mac address from the device has not been read yet. cc: stable(a)vger.kernel.org # 6.6+ Fixes: d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by: Jarkko Palviainen <jarkko.palviainen(a)gmail.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm(a)redhat.com> --- drivers/net/usb/ax88179_178a.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/net/usb/ax88179_178a.c b/drivers/net/usb/ax88179_178a.c index 69169842fa2f..650bb7b6badf 100644 --- a/drivers/net/usb/ax88179_178a.c +++ b/drivers/net/usb/ax88179_178a.c @@ -174,6 +174,7 @@ struct ax88179_data { u32 wol_supported; u32 wolopts; u8 disconnecting; + u8 mac_address_read; }; struct ax88179_int_data { @@ -969,9 +970,12 @@ static int ax88179_change_mtu(struct net_device *net, int new_mtu) static int ax88179_set_mac_addr(struct net_device *net, void *p) { struct usbnet *dev = netdev_priv(net); + struct ax88179_data *ax179_data = dev->driver_priv; struct sockaddr *addr = p; int ret; + if (!ax179_data->mac_address_read) + return -EAGAIN; if (netif_running(net)) return -EBUSY; if (!is_valid_ether_addr(addr->sa_data)) @@ -1256,6 +1260,7 @@ static int ax88179_led_setting(struct usbnet *dev) static void ax88179_get_mac_addr(struct usbnet *dev) { + struct ax88179_data *ax179_data = dev->driver_priv; u8 mac[ETH_ALEN]; memset(mac, 0, sizeof(mac)); @@ -1281,6 +1286,9 @@ static void ax88179_get_mac_addr(struct usbnet *dev) ax88179_write_cmd(dev, AX_ACCESS_MAC, AX_NODE_ID, ETH_ALEN, ETH_ALEN, dev->net->dev_addr); + + ax179_data->mac_address_read = 1; + netdev_info(dev->net, "MAC address: %pM\n", dev->net->dev_addr); } static int ax88179_bind(struct usbnet *dev, struct usb_interface *intf) -- 2.44.0

[Request] backport a mainline patch to Linux kernel-5.10 stable tree

by Bo Ye (叶波)

Dear Reviewers, we suggest to backport a commit to Linux kernel-5.10 stable tree to fix thermal bug. Thanks a lot source patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/d… thermal: core: Fix thermal zone suspend-resume synchronization There are 3 synchronization issues with thermal zone suspend-resume during system-wide transitions: 1. The resume code runs in a PM notifier which is invoked after user space has been thawed, so it can run concurrently with user space which can trigger a thermal zone device removal. If that happens, the thermal zone resume code may use a stale pointer to the next list element and crash, because it does not hold thermal_list_lock while walking thermal_tz_list. 2. The thermal zone resume code calls thermal_zone_device_init() outside the zone lock, so user space or an update triggered by the platform firmware may see an inconsistent state of a thermal zone leading to unexpected behavior. 3. Clearing the in_suspend global variable in thermal_pm_notify() allows __thermal_zone_device_update() to continue for all thermal zones and it may as well run before the thermal_tz_list walk (or at any point during the list walk for that matter) and attempt to operate on a thermal zone that has not been resumed yet. It may also race destructively with thermal_zone_device_init(). To address these issues, add thermal_list_lock locking to thermal_pm_notify(), especially arount the thermal_tz_list, make it call thermal_zone_device_init() back-to-back with __thermal_zone_device_update() under the zone lock and replace in_suspend with per-zone bool "suspend" indicators set and unset under the given zone's lock.

[merged mm-hotfixes-stable] mm-madvise-make-madv_populate_readwrite-handle-vm_fault_retry-properly.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/madvise: make MADV_POPULATE_(READ|WRITE) handle VM_FAULT_RETRY properly has been removed from the -mm tree. Its filename was mm-madvise-make-madv_populate_readwrite-handle-vm_fault_retry-properly.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/madvise: make MADV_POPULATE_(READ|WRITE) handle VM_FAULT_RETRY properly Date: Thu, 14 Mar 2024 17:12:59 +0100 Darrick reports that in some cases where pread() would fail with -EIO and mmap()+access would generate a SIGBUS signal, MADV_POPULATE_READ / MADV_POPULATE_WRITE will keep retrying forever and not fail with -EFAULT. While the madvise() call can be interrupted by a signal, this is not the desired behavior. MADV_POPULATE_READ / MADV_POPULATE_WRITE should behave like page faults in that case: fail and not retry forever. A reproducer can be found at [1]. The reason is that __get_user_pages(), as called by faultin_vma_page_range(), will not handle VM_FAULT_RETRY in a proper way: it will simply return 0 when VM_FAULT_RETRY happened, making madvise_populate()->faultin_vma_page_range() retry again and again, never setting FOLL_TRIED->FAULT_FLAG_TRIED for __get_user_pages(). __get_user_pages_locked() does what we want, but duplicating that logic in faultin_vma_page_range() feels wrong. So let's use __get_user_pages_locked() instead, that will detect VM_FAULT_RETRY and set FOLL_TRIED when retrying, making the fault handler return VM_FAULT_SIGBUS (VM_FAULT_ERROR) at some point, propagating -EFAULT from faultin_page() to __get_user_pages(), all the way to madvise_populate(). But, there is an issue: __get_user_pages_locked() will end up re-taking the MM lock and then __get_user_pages() will do another VMA lookup. In the meantime, the VMA layout could have changed and we'd fail with different error codes than we'd want to. As __get_user_pages() will currently do a new VMA lookup either way, let it do the VMA handling in a different way, controlled by a new FOLL_MADV_POPULATE flag, effectively moving these checks from madvise_populate() + faultin_page_range() in there. With this change, Darricks reproducer properly fails with -EFAULT, as documented for MADV_POPULATE_READ / MADV_POPULATE_WRITE.

Therefore, a patch to resize the nilfs_type_by_mode array should be applied to prevent OOB errors.

The quilt patch titled Subject: Squashfs: check the inode number is not the invalid value of zero has been removed from the -mm tree. Its filename was squashfs-check-the-inode-number-is-not-the-invalid-value-of-zero.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Phillip Lougher <phillip(a)squashfs.org.uk> Subject: Squashfs: check the inode number is not the invalid value of zero Date: Mon, 8 Apr 2024 23:02:06 +0100 Syskiller has produced an out of bounds access in fill_meta_index(). That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked. The reason this causes the out of bounds access is due to following sequence of events: 1. Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number). 2. When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed. This patch adds a sanity check which checks that the inode number is not zero when the inode is created and returns -EINVAL if it is.

[merged mm-hotfixes-stable] mmswapops-update-check-in-is_pfn_swap_entry-for-hwpoison-entries.patch removed from -mm tree

The quilt patch titled Subject: mm,swapops: update check in is_pfn_swap_entry for hwpoison entries has been removed from the -mm tree. Its filename was mmswapops-update-check-in-is_pfn_swap_entry-for-hwpoison-entries.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Oscar Salvador <osalvador(a)suse.de> Subject: mm,swapops: update check in is_pfn_swap_entry for hwpoison entries Date: Sun, 7 Apr 2024 15:05:37 +0200 Tony reported that the Machine check recovery was broken in v6.9-rc1, as he was hitting a VM_BUG_ON when injecting uncorrectable memory errors to DRAM. After some more digging and debugging on his side, he realized that this went back to v6.1, with the introduction of 'commit 0d206b5d2e0d ("mm/swap: add swp_offset_pfn() to fetch PFN from swap entry")'. That commit, among other things, introduced swp_offset_pfn(), replacing hwpoison_entry_to_pfn() in its favour. The patch also introduced a VM_BUG_ON() check for is_pfn_swap_entry(), but is_pfn_swap_entry() never got updated to cover hwpoison entries, which means that we would hit the VM_BUG_ON whenever we would call swp_offset_pfn() for such entries on environments with CONFIG_DEBUG_VM set. Fix this by updating the check to cover hwpoison entries as well, and update the comment while we are it.

[merged mm-hotfixes-stable] mm-userfaultfd-allow-hugetlb-change-protection-upon-poison-entry.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/userfaultfd: allow hugetlb change protection upon poison entry has been removed from the -mm tree. Its filename was mm-userfaultfd-allow-hugetlb-change-protection-upon-poison-entry.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Peter Xu <peterx(a)redhat.com> Subject: mm/userfaultfd: allow hugetlb change protection upon poison entry Date: Fri, 5 Apr 2024 19:19:20 -0400 After UFFDIO_POISON, there can be two kinds of hugetlb pte markers, either the POISON one or UFFD_WP one. Allow change protection to run on a poisoned marker just like !hugetlb cases, ignoring the marker irrelevant of the permission. Here the two bits are mutual exclusive. For example, when install a poisoned entry it must not be UFFD_WP already (by checking pte_none() before such install). And it also means if UFFD_WP is set there must have no POISON bit set. It makes sense because UFFD_WP is a bit to reflect permission, and permissions do not apply if the pte is poisoned and destined to sigbus. So here we simply check uffd_wp bit set first, do nothing otherwise. Attach the Fixes to UFFDIO_POISON work, as before that it should not be possible to have poison entry for hugetlb (e.g., hugetlb doesn't do swap, so no chance of swapin errors).

[PATCH v2] rust: macros: fix soundness issue in `module!` macro

by Benno Lossin

The `module!` macro creates glue code that are called by C to initialize the Rust modules using the `Module::init` function. Part of this glue code are the local functions `__init` and `__exit` that are used to initialize/destroy the Rust module. These functions are safe and also visible to the Rust mod in which the `module!` macro is invoked. This means that they can be called by other safe Rust code. But since they contain `unsafe` blocks that rely on only being called at the right time, this is a soundness issue. Wrap these generated functions inside of two private modules, this guarantees that the public functions cannot be called from the outside. Make the safe functions `unsafe` and add SAFETY comments.

[PATCH V2 1/8] clk: qcom: clk-alpha-pll: Fix CAL_L_VAL override for LUCID EVO PLL

by Ajit Pandey

In LUCID EVO PLL CAL_L_VAL and L_VAL bitfields are part of single PLL_L_VAL register. Update for L_VAL bitfield values in PLL_L_VAL register using regmap_write() API in __alpha_pll_trion_set_rate callback will override LUCID EVO PLL initial configuration related to PLL_CAL_L_VAL bit fields in PLL_L_VAL register. Observed random PLL lock failures during PLL enable due to such override in PLL calibration value. Use regmap_update_bits() with L_VAL bitfield mask instead of regmap_write() API to update only PLL_L_VAL bitfields in __alpha_pll_trion_set_rate callback.

[PATCH] block: Fix BLKRRPART regression

by Saranya Muruganandam

The BLKRRPART ioctl used to report errors such as EIO before we changed the blkdev_reread_part() logic. Lets add a flag and capture the errors returned by bdev_disk_changed() when the flag is set. Setting this flag for the BLKRRPART path when we want the errors to be reported when rereading partitions on the disk. Link: https://lore.kernel.org/all/20240320015134.GA14267@lst.de/ Suggested-by: Christoph Hellwig <hch(a)lst.de> Tested: Tested by simulating failure to the block device and will propose a new test to blktests.

[PATCH] mmc: sdhci-msm: pervent access to suspended controller

by Mantas Pucka

Generic sdhci code registers LED device and uses host->runtime_suspended flag to protect access to it. The sdhci-msm driver doesn't set this flag, which causes a crash when LED is accessed while controller is runtime suspended. Fix this by setting the flag correctly.

[PATCH] dm: Change the default value of rq_affinity from 0 into 1

by Bart Van Assche

The following behavior is inconsistent: * For request-based dm queues the default value of rq_affinity is 1. * For bio-based dm queues the default value of rq_affinity is 0. The default value for request-based dm queues is 1 because of the following code in blk_mq_init_allocated_queue(): q->queue_flags |= QUEUE_FLAG_MQ_DEFAULT; From <linux/blkdev.h>: #define QUEUE_FLAG_MQ_DEFAULT ((1UL << QUEUE_FLAG_IO_STAT) | \ (1UL << QUEUE_FLAG_SAME_COMP) | \ (1UL << QUEUE_FLAG_NOWAIT)) The default value of rq_affinity for bio-based dm queues is 0 because the dm alloc_dev() function does not set any of the QUEUE_FLAG_SAME_* flags. I think the different default values are the result of an oversight when blk-mq support was added in the device mapper code. Hence this patch that changes the default value of rq_affinity from 0 to 1 for bio-based dm queues. This patch reduces the boot time from 12.23 to 12.20 seconds on my test setup, a Pixel 2023 development board. The storage controller on that test setup supports a single completion interrupt and hence benefits from redirecting I/O completions to a CPU core that is closer to the submitter.

[PATCH 1/2] sched: Add missing memory barrier in switch_mm_cid

by Mathieu Desnoyers

Many architectures' switch_mm() (e.g. arm64) do not have an smp_mb() which the core scheduler code has depended upon since commit: commit 223baf9d17f25 ("sched: Fix performance regression introduced by mm_cid") If switch_mm() doesn't call smp_mb(), sched_mm_cid_remote_clear() can unset the actively used cid when it fails to observe active task after it sets lazy_put. There *is* a memory barrier between storing to rq->curr and _return to userspace_ (as required by membarrier), but the rseq mm_cid has stricter requirements: the barrier needs to be issued between store to rq->curr and switch_mm_cid(), which happens earlier than: - spin_unlock(), - switch_to(). So it's fine when the architecture switch_mm() happens to have that barrier already, but less so when the architecture only provides the full barrier in switch_to() or spin_unlock(). It is a bug in the rseq switch_mm_cid() implementation. All architectures that don't have memory barriers in switch_mm(), but rather have the full barrier either in finish_lock_switch() or switch_to() have them too late for the needs of switch_mm_cid(). Introduce a new smp_mb__after_switch_mm(), defined as smp_mb() in the generic barrier.h header, and use it in switch_mm_cid() for scheduler transitions where switch_mm() is expected to provide a memory barrier. Architectures can override smp_mb__after_switch_mm() if their switch_mm() implementation provides an implicit memory barrier. Override it with a no-op on x86 which implicitly provide this memory barrier by writing to CR3.

[PATCH 0/7] kdb: Refactor and fix bugs in kdb_read()

Inspired by a patch from [Justin][1] I took a closer look at kdb_read(). Despite Justin's patch being a (correct) one-line manipulation it was a tough patch to review because the surrounding code was hard to read and it looked like there were unfixed problems. This series isn't enough to make kdb_read() beautiful but it does make it shorter, easier to reason about and fixes a buffer overflow and a screen redraw problem!

[PATCH] Revert "Bluetooth: hci_qca: Set BDA quirk bit if fwnode exists in DT"

by Johan Hovold

This reverts commit 7dcd3e014aa7faeeaf4047190b22d8a19a0db696. Qualcomm Bluetooth controllers like WCN6855 do not have persistent storage for the Bluetooth address and must therefore start as unconfigured to allow the user to set a valid address unless one has been provided by the boot firmware in the devicetree. A recent change snuck into v6.8-rc7 and incorrectly started marking the default (non-unique) address as valid. This specifically also breaks the Bluetooth setup for some user of the Lenovo ThinkPad X13s. Note that this is the second time Qualcomm breaks the driver this way and that this was fixed last year by commit 6945795bc81a ("Bluetooth: fix use-bdaddr-property quirk"), which also has some further details.

Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.

[PATCH] usb: dwc3: ep0: Don't reset resource alloc flag

by Thinh Nguyen

The DWC3_EP_RESOURCE_ALLOCATED flag ensures that the resource of an endpoint is only assigned once. Unless the endpoint is reset, don't clear this flag. Otherwise we may set endpoint resource again, which prevents the driver from initiate transfer after handling a STALL or endpoint halt to the control endpoint.

So it doesn't make sense to free memory back to memblock. memblock_free() called by xbc_exit() even causes UAF bugs on architectures with CONFIG_ARCH_KEEP_MEMBLOCK disabled like x86. Following KASAN logs shows this case. This patch fixes the xbc memory free problem by calling memblock_free() in early xbc init error rewind path and calling memblock_free_late() in xbc exit path to free memory to buddy allocator.

[PATCH] dm: Change the default value of rq_affinity from 0 into 1

by Bart Van Assche

The following behavior is inconsistent: * For request-based dm queues the default value of rq_affinity is 1. * For bio-based dm queues the default value of rq_affinity is 0. The default value for request-based dm queues is 1 because of the following code in blk_mq_init_allocated_queue(): q->queue_flags |= QUEUE_FLAG_MQ_DEFAULT; From <linux/blkdev.h>: #define QUEUE_FLAG_MQ_DEFAULT ((1UL << QUEUE_FLAG_IO_STAT) | \ (1UL << QUEUE_FLAG_SAME_COMP) | \ (1UL << QUEUE_FLAG_NOWAIT)) The default value of rq_affinity for bio-based dm queues is 0 because the dm alloc_dev() function does not set any of the QUEUE_FLAG_SAME_* flags. I think the different default values are the result of an oversight when blk-mq support was added in the device mapper code. Hence this patch that changes the default value of rq_affinity from 0 to 1 for bio-based dm queues. This patch reduces the boot time from 12.23 to 12.20 seconds on my test setup, a Pixel 2023 development board. The storage controller on that test setup supports a single completion interrupt and hence benefits from redirecting I/O completions to a CPU core that is closer to the submitter.

Therefore, a patch to resize the nilfs_type_by_mode array should be applied to prevent OOB errors.

We could prevent from that race by serializing i915_active_fini() with __active_retire() via ref->tree_lock, but that wouldn't stop the VMA from being used, e.g. from __i915_vma_retire() called at the end of __active_retire(), after that VMA has been already freed by a concurrent i915_vma_destroy() on return from the i915_active_fini(). Then, we should rather fix the issue at the VMA level, not in i915_active. Since __i915_vma_parked() is called from __gt_park() on last put of the GT's wakeref, the issue could be addressed by holding the GT wakeref long enough for __active_retire() to complete before that wakeref is released and the GT parked. I believe the issue was introduced by commit d93939730347 ("drm/i915: Remove the vma refcount") which moved a call to i915_active_fini() from a dropped i915_vma_release(), called on last put of the removed VMA kref, to i915_vma_parked() processing path called on last put of a GT wakeref. However, its visibility to the object debugging tool was suppressed by a bug in i915_active that was fixed two weeks later with commit e92eb246feb9 ("drm/i915/active: Fix missing debug object activation"). A VMA associated with a request doesn't acquire a GT wakeref by itself. Instead, it depends on a wakeref held directly by the request's active intel_context for a GT associated with its VM, and indirectly on that intel_context's engine wakeref if the engine belongs to the same GT as the VMA's VM. Those wakerefs are released asynchronously to VMA deactivation. Fix the issue by getting a wakeref for the VMA's GT when activating it, and putting that wakeref only after the VMA is deactivated. However, exclude global GTT from that processing path, otherwise the GPU never goes idle. Since __i915_vma_retire() may be called from atomic contexts, use async variant of wakeref put. Also, to avoid circular locking dependency, take care of acquiring the wakeref before VM mutex when both are needed. v7: Add inline comments with justifications for: - using untracked variants of intel_gt_pm_get/put() (Nirmoy), - using async variant of _put(), - not getting the wakeref in case of a global GTT, - always getting the first wakeref outside vm->mutex. v6: Since __i915_vma_active/retire() callbacks are not serialized, storing a wakeref tracking handle inside struct i915_vma is not safe, and there is no other good place for that. Use untracked variants of intel_gt_pm_get/put_async(). v5: Replace "tile" with "GT" across commit description (Rodrigo), - avoid mentioning multi-GT case in commit description (Rodrigo), - explain why we need to take a temporary wakeref unconditionally inside i915_vma_pin_ww() (Rodrigo). v4: Refresh on top of commit 5e4e06e4087e ("drm/i915: Track gt pm wakerefs") (Andi), - for more easy backporting, split out removal of former insufficient workarounds and move them to separate patches (Nirmoy). - clean up commit message and description a bit. v3: Identify root cause more precisely, and a commit to blame, - identify and drop former workarounds, - update commit message and description. v2: Get the wakeref before VM mutex to avoid circular locking dependency, - drop questionable Fixes: tag.

[PATCH 6.6] Revert "dm-crypt, dm-verity: disable tasklets"

by Li Lingfeng

This reverts commit 5735a2671ffb70ea29ca83969fe01316ee2ed6fc which is commit 0a9bab391e336489169b95cb0d4553d921302189 upstream. Tasklet is thought to cause memory corruption [1], so it was disabled in dm-crypt and dm-verity. However, memory corruption may not happen since cc->io_queue is created without WQ_UNBOUND [2]. Revert commit 5735a2671ffb ("dm-crypt, dm-verity: disable tasklets") to bring tasklet back.

Also, to avoid circular locking dependency, take care of acquiring the wakeref before VM mutex when both are needed. v7: Add inline comments with justifications for: - using untracked variants of intel_gt_pm_get/put() (Nirmoy), - using async variant of _put(), - not getting the wakeref in case of a global GTT, - always getting the first wakeref outside vm->mutex. v6: Since __i915_vma_active/retire() callbacks are not serialized, storing a wakeref tracking handle inside struct i915_vma is not safe, and there is no other good place for that. Use untracked variants of intel_gt_pm_get/put_async(). v5: Replace "tile" with "GT" across commit description (Rodrigo), - avoid mentioning multi-GT case in commit description (Rodrigo), - explain why we need to take a temporary wakeref unconditionally inside i915_vma_pin_ww() (Rodrigo). v4: Refresh on top of commit 5e4e06e4087e ("drm/i915: Track gt pm wakerefs") (Andi), - for more easy backporting, split out removal of former insufficient workarounds and move them to separate patches (Nirmoy). - clean up commit message and description a bit. v3: Identify root cause more precisely, and a commit to blame, - identify and drop former workarounds, - update commit message and description. v2: Get the wakeref before VM mutex to avoid circular locking dependency, - drop questionable Fixes: tag.

[PATCH 4.14-openela 009/190] block: fix signed int overflow in Amiga partition support

by Sasha Levin

From: Michael Schmitz <schmitzmic(a)gmail.com> [ Upstream commit fc3d092c6bb48d5865fec15ed5b333c12f36288c ] The Amiga partition parser module uses signed int for partition sector address and count, which will overflow for disks larger than 1 TB. Use sector_t as type for sector address and size to allow using disks up to 2 TB without LBD support, and disks larger than 2 TB with LBD. This bug was reported originally in 2012, and the fix was created by the RDB author, Joanne Dow <jdow(a)earthlink.net>. A patch had been discussed and reviewed on linux-m68k at that time but never officially submitted. This patch differs from Joanne's patch only in its use of sector_t instead of unsigned int. No checking for overflows is done (see patch 3 of this series for that). Reported-by: Martin Steigerwald <Martin(a)lichtvoll.de> Closes: https://bugzilla.kernel.org/show_bug.cgi?id=43511 Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Message-ID: <201206192146.09327.Martin(a)lichtvoll.de> Cc: <stable(a)vger.kernel.org> # 5.2 Signed-off-by: Michael Schmitz <schmitzmic(a)gmail.com> Tested-by: Martin Steigerwald <Martin(a)lichtvoll.de> Reviewed-by: Geert Uytterhoeven <geert(a)linux-m68k.org> Reviewed-by: Christoph Hellwig <hch(a)lst.de> Link: https://lore.kernel.org/r/20230620201725.7020-2-schmitzmic@gmail.com Signed-off-by: Jens Axboe <axboe(a)kernel.dk> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- block/partitions/amiga.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/block/partitions/amiga.c b/block/partitions/amiga.c index 560936617d9c1..4a4160221183b 100644 --- a/block/partitions/amiga.c +++ b/block/partitions/amiga.c @@ -32,7 +32,8 @@ int amiga_partition(struct parsed_partitions *state) unsigned char *data; struct RigidDiskBlock *rdb; struct PartitionBlock *pb; - int start_sect, nr_sects, blk, part, res = 0; + sector_t start_sect, nr_sects; + int blk, part, res = 0; int blksize = 1; /* Multiplier for disk block size */ int slot = 1; char b[BDEVNAME_SIZE]; @@ -100,14 +101,14 @@ int amiga_partition(struct parsed_partitions *state) /* Tell Kernel about it */ - nr_sects = (be32_to_cpu(pb->pb_Environment[10]) + 1 - - be32_to_cpu(pb->pb_Environment[9])) * + nr_sects = ((sector_t)be32_to_cpu(pb->pb_Environment[10]) + 1 - + be32_to_cpu(pb->pb_Environment[9])) * be32_to_cpu(pb->pb_Environment[3]) * be32_to_cpu(pb->pb_Environment[5]) * blksize; if (!nr_sects) continue; - start_sect = be32_to_cpu(pb->pb_Environment[9]) * + start_sect = (sector_t)be32_to_cpu(pb->pb_Environment[9]) * be32_to_cpu(pb->pb_Environment[3]) * be32_to_cpu(pb->pb_Environment[5]) * blksize; -- 2.43.0

When quota groups (squota or qgroups) are enabled, this reserves qgroup metadata of type PREALLOC. Once the operation is associated to a transaction, we convert PREALLOC to PERTRANS, which gets cleared in bulk at the end of the transaction. However, the error paths of these three operations were not implementing this lifecycle correctly. They unconditionally converted the PREALLOC to PERTRANS in a generic cleanup step regardless of errors or whether the operation was fully associated to a transaction or not. This resulted in error paths occasionally converting this rsv to PERTRANS without calling record_root_in_trans successfully, which meant that unless that root got recorded in the transaction by some other thread, the end of the transaction would not free that root's PERTRANS, leaking it. Ultimately, this resulted in hitting a WARN in CONFIG_BTRFS_DEBUG builds at unmount for the leaked reservation. The fix is to ensure that every qgroup PREALLOC reservation observes the following properties: 1. any failure before record_root_in_trans is called successfully results in freeing the PREALLOC reservation. 2. after record_root_in_trans, we convert to PERTRANS, and now the transaction owns freeing the reservation. This patch enforces those properties on the three operations. Without it, generic/269 with squotas enabled at mkfs time would fail in ~5-10 runs on my system. With this patch, it ran successfully 1000 times in a row.

[PATCH 4.14-openela 049/190] usb: musb: fix MUSB_QUIRK_B_DISCONNECT_99 handling

by Sasha Levin

From: Thomas Petazzoni <thomas.petazzoni(a)bootlin.com> [ Upstream commit b65ba0c362be665192381cc59e3ac3ef6f0dd1e1 ] In commit 92af4fc6ec33 ("usb: musb: Fix suspend with devices connected for a64"), the logic to support the MUSB_QUIRK_B_DISCONNECT_99 quirk was modified to only conditionally schedule the musb->irq_work delayed work. This commit badly breaks ECM Gadget on AM335X. Indeed, with this commit, one can observe massive packet loss: $ ping 192.168.0.100 ... 15 packets transmitted, 3 received, 80% packet loss, time 14316ms Reverting this commit brings back a properly functioning ECM Gadget. An analysis of the commit seems to indicate that a mistake was made: the previous code was not falling through into the MUSB_QUIRK_B_INVALID_VBUS_91, but now it is, unless the condition is taken. Changing the logic to be as it was before the problematic commit *and* only conditionally scheduling musb->irq_work resolves the regression: $ ping 192.168.0.100 ... 64 packets transmitted, 64 received, 0% packet loss, time 64475ms Fixes: 92af4fc6ec33 ("usb: musb: Fix suspend with devices connected for a64") Cc: stable(a)vger.kernel.org Tested-by: Alexandre Belloni <alexandre.belloni(a)bootlin.com> Tested-by: Drew Fustini <drew(a)beagleboard.org> Acked-by: Tony Lindgren <tony(a)atomide.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni(a)bootlin.com> Link: https://lore.kernel.org/r/20210528140446.278076-1-thomas.petazzoni@bootlin.… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- drivers/usb/musb/musb_core.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/usb/musb/musb_core.c b/drivers/usb/musb/musb_core.c index 9ed604ddbb585..580f4c12eada3 100644 --- a/drivers/usb/musb/musb_core.c +++ b/drivers/usb/musb/musb_core.c @@ -1869,9 +1869,8 @@ static void musb_pm_runtime_check_session(struct musb *musb) schedule_delayed_work(&musb->irq_work, msecs_to_jiffies(1000)); musb->quirk_retries--; - break; } - /* fall through */ + break; case MUSB_QUIRK_B_INVALID_VBUS_91: if (musb->quirk_retries && !musb->flush_irq_work) { musb_dbg(musb, -- 2.43.0

[PATCH 4.14-openela 044/190] PCI: keystone: Don't discard .remove() callback

by Sasha Levin

From: Uwe Kleine-König <u.kleine-koenig(a)pengutronix.de> [ Upstream commit 200bddbb3f5202bbce96444fdc416305de14f547 ] With CONFIG_PCIE_KEYSTONE=y and ks_pcie_remove() marked with __exit, the function is discarded from the driver. In this case a bound device can still get unbound, e.g via sysfs. Then no cleanup code is run resulting in resource leaks or worse. The right thing to do is do always have the remove callback available. Note that this driver cannot be compiled as a module, so ks_pcie_remove() was always discarded before this change and modpost couldn't warn about this issue. Furthermore the __ref annotation also prevents a warning.

[PATCH 4.14-openela 034/190] ASoC: cs42l51: fix driver to properly autoload with automatic module loading

by Sasha Levin

From: Thomas Petazzoni <thomas.petazzoni(a)bootlin.com> [ Upstream commit e51df4f81b02bcdd828a04de7c1eb6a92988b61e ] In commit 2cb1e0259f50 ("ASoC: cs42l51: re-hook of_match_table pointer"), 9 years ago, some random guy fixed the cs42l51 after it was split into a core part and an I2C part to properly match based on a Device Tree compatible string. However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of, ....) is in the core part of the driver, not the I2C part. Therefore, automatic module loading based on module.alias, based on matching with the DT compatible string, loads the core part of the driver, but not the I2C part. And threfore, the i2c_driver is not registered, and the codec is not known to the system, nor matched with a DT node with the corresponding compatible string. In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into the I2C part of the driver. The cs42l51_of_match[] array is also moved as well, as it is not possible to have this definition in one file, and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due to how MODULE_DEVICE_TABLE works. Thanks to this commit, the I2C part of the driver now properly autoloads, and thanks to its dependency on the core part, the core part gets autoloaded as well, resulting in a functional sound card without having to manually load kernel modules.
