[PATCH 0/2 4.19.y] ALSA: usb-audio: sanity checks for pipes

by Dan Carpenter

Backporting the sanity checks on pipes seems like a good idea. These are basically the same as Takashi Iwai's patches upstream. The difference is that upstream added two sanity checks to code that doesn't exist in 4.19. I had talked about backporting fcc2cc1f3561 ("USB: move snd_usb_pipe_sanity_check into the USB core") but that's just a refactor and not a bug fix.

[PATCH 6/8] serial: qcom-geni: fix console corruption

by Johan Hovold

The Qualcomm serial console implementation is broken and can lose characters when the serial port is also used for tty output. Specifically, the console code only waits for the current tx command to complete when all data has already been written to the fifo. When there are on-going longer transfers this often means that console output is lost when the console code inadvertently "hijacks" the current tx command instead of starting a new one. This can, for example, be observed during boot when console output that should have been interspersed with init output is truncated: [ 9.462317] qcom-snps-eusb2-hsphy fde000.phy: Registered Qcom-eUSB2 phy [ OK ] Found device KBG50ZNS256G KIOXIA Wi[ 9.471743ndows. [ 9.539915] xhci-hcd xhci-hcd.0.auto: xHCI Host Controller Add a new state variable to track how much data has been written to the fifo and use it to determine when the fifo and shift register are both empty. This is needed since there is currently no other known way to determine when the shift register is empty. This in turn allows the console code to interrupt long transfers without losing data. Note that the oops-in-progress case is similarly broken as it does not cancel any active command and also waits for the wrong status flag when attempting to drain the fifo (TX_FIFO_NOT_EMPTY_EN is only set when cancelling a command leaves data in the fifo).

[git:media_tree/master] media: qcom: camss: Remove use_count guard in stop_streaming

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: qcom: camss: Remove use_count guard in stop_streaming Author: Bryan O'Donoghue <bryan.odonoghue(a)linaro.org> Date: Mon Jul 29 13:42:02 2024 +0100 The use_count check was introduced so that multiple concurrent Raw Data Interfaces RDIs could be driven by different virtual channels VCs on the CSIPHY input driving the video pipeline. This is an invalid use of use_count though as use_count pertains to the number of times a video entity has been opened by user-space not the number of active streams. If use_count and stream-on count don't agree then stop_streaming() will break as is currently the case and has become apparent when using CAMSS with libcamera's released softisp 0.3. The use of use_count like this is a bit hacky and right now breaks regular usage of CAMSS for a single stream case. Stopping qcam results in the splat below, and then it cannot be started again and any attempts to do so fails with -EBUSY.

Either way refusing to release video buffers based on use_count is erroneous and should be reverted. The silicon enabling code for selecting VCs is perfectly fine. Its a "known missing feature" that concurrent VCs won't work with CAMSS right now. Initial testing with this code didn't show an error but, SoftISP and "real" usage with Google Hangouts breaks the upstream code pretty quickly, we need to do a partial revert and take another pass at VCs.

[PATCH] net: drop bad gso csum_start and offset in virtio_net_hdr

by mathieu.tortuyaux＠gmail.com

From: Mathieu Tortuyaux <mtortuyaux(a)microsoft.com> [ Upstream commit 89add40066f9ed9abe5f7f886fe5789ff7e0c50e ] Tighten csum_start and csum_offset checks in virtio_net_hdr_to_skb for GSO packets. The function already checks that a checksum requested with VIRTIO_NET_HDR_F_NEEDS_CSUM is in skb linear. But for GSO packets this might not hold for segs after segmentation. Syzkaller demonstrated to reach this warning in skb_checksum_help offset = skb_checksum_start_offset(skb); ret = -EINVAL; if (WARN_ON_ONCE(offset >= skb_headlen(skb))) By injecting a TSO packet: WARNING: CPU: 1 PID: 3539 at net/core/dev.c:3284 skb_checksum_help+0x3d0/0x5b0 ip_do_fragment+0x209/0x1b20 net/ipv4/ip_output.c:774 ip_finish_output_gso net/ipv4/ip_output.c:279 [inline] __ip_finish_output+0x2bd/0x4b0 net/ipv4/ip_output.c:301 iptunnel_xmit+0x50c/0x930 net/ipv4/ip_tunnel_core.c:82 ip_tunnel_xmit+0x2296/0x2c70 net/ipv4/ip_tunnel.c:813 __gre_xmit net/ipv4/ip_gre.c:469 [inline] ipgre_xmit+0x759/0xa60 net/ipv4/ip_gre.c:661 __netdev_start_xmit include/linux/netdevice.h:4850 [inline] netdev_start_xmit include/linux/netdevice.h:4864 [inline] xmit_one net/core/dev.c:3595 [inline] dev_hard_start_xmit+0x261/0x8c0 net/core/dev.c:3611 __dev_queue_xmit+0x1b97/0x3c90 net/core/dev.c:4261 packet_snd net/packet/af_packet.c:3073 [inline] The geometry of the bad input packet at tcp_gso_segment: [ 52.003050][ T8403] skb len=12202 headroom=244 headlen=12093 tailroom=0 [ 52.003050][ T8403] mac=(168,24) mac_len=24 net=(192,52) trans=244 [ 52.003050][ T8403] shinfo(txflags=0 nr_frags=1 gso(size=1552 type=3 segs=0)) [ 52.003050][ T8403] csum(0x60000c7 start=199 offset=1536 ip_summed=3 complete_sw=0 valid=0 level=0) Mitigate with stricter input validation. csum_offset: for GSO packets, deduce the correct value from gso_type. This is already done for USO. Extend it to TSO. Let UFO be: udp[46]_ufo_fragment ignores these fields and always computes the checksum in software. csum_start: finding the real offset requires parsing to the transport header. Do not add a parser, use existing segmentation parsing. Thanks to SKB_GSO_DODGY, that also catches bad packets that are hw offloaded. Again test both TSO and USO. Do not test UFO for the above reason, and do not test UDP tunnel offload. GSO packet are almost always CHECKSUM_PARTIAL. USO packets may be CHECKSUM_NONE since commit 10154db ("udp: Allow GSO transmit from devices with no checksum offload"), but then still these fields are initialized correctly in udp4_hwcsum/udp6_hwcsum_outgoing. So no need to test for ip_summed == CHECKSUM_PARTIAL first. This revises an existing fix mentioned in the Fixes tag, which broke small packets with GSO offload, as detected by kselftests.

[PATCH v4.19-v5.10] virtio_net: Fix napi_skb_cache_put warning

by Shivani Agarwal

From: Breno Leitao <leitao(a)debian.org> [ Upstream commit f8321fa75102246d7415a6af441872f6637c93ab ] After the commit bdacf3e34945 ("net: Use nested-BH locking for napi_alloc_cache.") was merged, the following warning began to appear: WARNING: CPU: 5 PID: 1 at net/core/skbuff.c:1451 napi_skb_cache_put+0x82/0x4b0 __warn+0x12f/0x340 napi_skb_cache_put+0x82/0x4b0 napi_skb_cache_put+0x82/0x4b0 report_bug+0x165/0x370 handle_bug+0x3d/0x80 exc_invalid_op+0x1a/0x50 asm_exc_invalid_op+0x1a/0x20 __free_old_xmit+0x1c8/0x510 napi_skb_cache_put+0x82/0x4b0 __free_old_xmit+0x1c8/0x510 __free_old_xmit+0x1c8/0x510 __pfx___free_old_xmit+0x10/0x10 The issue arises because virtio is assuming it's running in NAPI context even when it's not, such as in the netpoll case. To resolve this, modify virtnet_poll_tx() to only set NAPI when budget is available. Same for virtnet_poll_cleantx(), which always assumed that it was in a NAPI context.

[PATCH v3] usb: xhci: fix loss of data on Cadence xHC

by Pawel Laszczak

Streams should flush their TRB cache, re-read TRBs, and start executing TRBs from the beginning of the new dequeue pointer after a 'Set TR Dequeue Pointer' command. Cadence controllers may fail to start from the beginning of the dequeue TRB as it doesn't clear the Opaque 'RsvdO' field of the stream context during 'Set TR Dequeue' command. This stream context area is where xHC stores information about the last partially executed TD when a stream is stopped. xHC uses this information to resume the transfer where it left mid TD, when the stream is restarted. Patch fixes this by clearing out all RsvdO fields before initializing new Stream transfer using a 'Set TR Dequeue Pointer' command.

[PATCH v2] drm/panthor: flush FW AS caches in slow reset path

In the off-chance that waiting for the firmware to signal its booted status timed out in the fast reset path, one must flush the cache lines for the entire FW VM address space before reloading the regions, otherwise stale values eventually lead to a scheduler job timeout.

[PATCH 1/2] bpf, cgroups: Fix cgroup v2 fallback on v1/v2 mixed mode

by Connor O'Brien

From: Daniel Borkmann <daniel(a)iogearbox.net> commit 8520e224f547cd070c7c8f97b1fc6d58cff7ccaa upstream. Fix cgroup v1 interference when non-root cgroup v2 BPF programs are used. Back in the days, commit bd1060a1d671 ("sock, cgroup: add sock->sk_cgroup") embedded per-socket cgroup information into sock->sk_cgrp_data and in order to save 8 bytes in struct sock made both mutually exclusive, that is, when cgroup v1 socket tagging (e.g. net_cls/net_prio) is used, then cgroup v2 falls back to the root cgroup in sock_cgroup_ptr() (&cgrp_dfl_root.cgrp). The assumption made was "there is no reason to mix the two and this is in line with how legacy and v2 compatibility is handled" as stated in bd1060a1d671. However, with Kubernetes more widely supporting cgroups v2 as well nowadays, this assumption no longer holds, and the possibility of the v1/v2 mixed mode with the v2 root fallback being hit becomes a real security issue. Many of the cgroup v2 BPF programs are also used for policy enforcement, just to pick _one_ example, that is, to programmatically deny socket related system calls like connect(2) or bind(2). A v2 root fallback would implicitly cause a policy bypass for the affected Pods. In production environments, we have recently seen this case due to various circumstances: i) a different 3rd party agent and/or ii) a container runtime such as [0] in the user's environment configuring legacy cgroup v1 net_cls tags, which triggered implicitly mentioned root fallback. Another case is Kubernetes projects like kind [1] which create Kubernetes nodes in a container and also add cgroup namespaces to the mix, meaning programs which are attached to the cgroup v2 root of the cgroup namespace get attached to a non-root cgroup v2 path from init namespace point of view. And the latter's root is out of reach for agents on a kind Kubernetes node to configure. Meaning, any entity on the node setting cgroup v1 net_cls tag will trigger the bypass despite cgroup v2 BPF programs attached to the namespace root. Generally, this mutual exclusiveness does not hold anymore in today's user environments and makes cgroup v2 usage from BPF side fragile and unreliable. This fix adds proper struct cgroup pointer for the cgroup v2 case to struct sock_cgroup_data in order to address these issues; this implicitly also fixes the tradeoffs being made back then with regards to races and refcount leaks as stated in bd1060a1d671, and removes the fallback, so that cgroup v2 BPF programs always operate as expected.

[PATCH v4.19-v5.10] block: initialize integrity buffer to zero before writing it to media

by Shivani Agarwal

From: Christoph Hellwig <hch(a)lst.de> [ Upstream commit 899ee2c3829c5ac14bfc7d3c4a5846c0b709b78f ] Metadata added by bio_integrity_prep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory. Fix this by adding the __GFP_ZERO flag to allocations for writes.

[PATCH] drm/panthor: Restrict high priorities on group_create

by Mary Guillemard

We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service. We now only allow the DRM master or users with the CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM. As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do. Additionally, as those checks are performed at the ioctl level, panthor_group_create now only check for priority level validity.

[PATCH v2] x86/hyperv: fix kexec crash due to VP assist page corruption

by Anirudh Rayabharam

From: Anirudh Rayabharam (Microsoft) <anirudh(a)anirudhrb.com> commit 9636be85cc5b ("x86/hyperv: Fix hyperv_pcpu_input_arg handling when CPUs go online/offline") introduces a new cpuhp state for hyperv initialization. cpuhp_setup_state() returns the state number if state is CPUHP_AP_ONLINE_DYN or CPUHP_BP_PREPARE_DYN and 0 for all other states. For the hyperv case, since a new cpuhp state was introduced it would return 0. However, in hv_machine_shutdown(), the cpuhp_remove_state() call is conditioned upon "hyperv_init_cpuhp > 0". This will never be true and so hv_cpu_die() won't be called on all CPUs. This means the VP assist page won't be reset. When the kexec kernel tries to setup the VP assist page again, the hypervisor corrupts the memory region of the old VP assist page causing a panic in case the kexec kernel is using that memory elsewhere. This was originally fixed in commit dfe94d4086e4 ("x86/hyperv: Fix kexec panic/hang issues"). Get rid of hyperv_init_cpuhp entirely since we are no longer using a dynamic cpuhp state and use CPUHP_AP_HYPERV_ONLINE directly with cpuhp_remove_state().

[PATCH V2] mm/gup: Clear the LRU flag of a page before adding to LRU batch

by yangge1116＠126.com

From: yangge <yangge1116(a)126.com> If a large number of CMA memory are configured in system (for example, the CMA memory accounts for 50% of the system memory), starting a virtual virtual machine, it will call pin_user_pages_remote(..., FOLL_LONGTERM, ...) to pin memory. Normally if a page is present and in CMA area, pin_user_pages_remote() will migrate the page from CMA area to non-CMA area because of FOLL_LONGTERM flag. But the current code will cause the migration failure due to unexpected page refcounts, and eventually cause the virtual machine fail to start. If a page is added in LRU batch, its refcount increases one, remove the page from LRU batch decreases one. Page migration requires the page is not referenced by others except page mapping. Before migrating a page, we should try to drain the page from LRU batch in case the page is in it, however, folio_test_lru() is not sufficient to tell whether the page is in LRU batch or not, if the page is in LRU batch, the migration will fail. To solve the problem above, we modify the logic of adding to LRU batch. Before adding a page to LRU batch, we clear the LRU flag of the page so that we can check whether the page is in LRU batch by folio_test_lru(page). Seems making the LRU flag of the page invisible a long time is no problem, because a new page is allocated from buddy and added to the lru batch, its LRU flag is also not visible for a long time.

[PATCH 1/1] iommu/vt-d: Prevent boot failure with devices requiring ATS

by Lu Baolu

SOC-integrated devices on some platforms require their PCI ATS enabled for operation when the IOMMU is in scalable mode. Those devices are reported via ACPI/SATC table with the ATC_REQUIRED bit set in the Flags field. The PCI subsystem offers the 'pci=noats' kernel command to disable PCI ATS on all devices. Using 'pci=noat' with devices that require PCI ATS can cause a conflict, leading to boot failure, especially if the device is a graphics device. To prevent this issue, check PCI ATS support before enumerating the IOMMU devices. If any device requires PCI ATS, but PCI ATS is disabled by 'pci=noats', switch the IOMMU to operate in legacy mode to ensure successful booting.

[for-linus][PATCH 3/6] tracing/timerlat: Only clear timer if a kthread exists

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> The timerlat tracer can use user space threads to check for osnoise and timer latency. If the program using this is killed via a SIGTERM, the threads are shutdown one at a time and another tracing instance can start up resetting the threads before they are fully closed. That causes the hrtimer assigned to the kthread to be shutdown and freed twice when the dying thread finally closes the file descriptors, causing a use-after-free bug. Only cancel the hrtimer if the associated thread is still around. Note, this is just a quick fix that can be backported to stable. A real fix is to have a better synchronization between the shutdown of old threads and the starting of new ones.

[PATCH 8/8] serial: qcom-geni: fix polled console corruption

by Johan Hovold

The polled UART operations are used by the kernel debugger (KDB, KGDB), which can interrupt the kernel at any point in time. The current Qualcomm GENI implementation does not really work when there is on-going serial output as it inadvertently "hijacks" the current tx command, which can result in both the initial debugger output being corrupted as well as the corruption of any on-going serial output (up to 4k characters) when execution resumes: 0190: abcdefghijklmnopqrstuvwxyz0123456789 0190: abcdefghijklmnopqrstuvwxyz0123456789 0191: abcdefghijklmnop[ 50.825552] sysrq: DEBUG qrstuvwxyz0123456789 0191: abcdefghijklmnopqrstuvwxyz0123456789 Entering kdb (current=0xffff53510b4cd280, pid 640) on processor 2 due to Keyboard Entry [2]kdb> go omlji3h3h2g2g1f1f0e0ezdzdycycxbxbwawav :t72r2rp o9n976k5j5j4i4i3h3h2g2g1f1f0e0ezdzdycycxbxbwawavu:t7t8s8s8r2r2q0q0p o9n9n8ml6k6k5j5j4i4i3h3h2g2g1f1f0e0ezdzdycycxbxbwawav v u:u:t9t0s4s4rq0p o9n9n8m8m7l7l6k6k5j5j40q0p p o o9n9n8m8m7l7l6k6k5j5j4i4i3h3h2g2g1f1f0e0ezdzdycycxbxbwawav :t8t9s4s4r4r4q0q0p Fix this by making sure that the polled output implementation waits for the tx fifo to drain before cancelling any on-going longer transfers. As the polled code cannot take any locks, leave the state variables as they are and instead make sure that the interrupt handler always starts a new tx command when there is data in the write buffer. Since the debugger can interrupt the interrupt handler when it is writing data to the tx fifo, it is currently not possible to fully prevent losing up to 64 bytes of tty output on resume.

[PATCH 2/8] serial: qcom-geni: fix false console tx restart

by Johan Hovold

Commit 663abb1a7a7f ("tty: serial: qcom_geni_serial: Fix UART hang") addressed an issue with stalled tx after the console code interrupted the last bytes of a tx command by reenabling the watermark interrupt if there is data in write buffer. This can however break software flow control by re-enabling tx after the user has stopped it. Address the original issue by not clearing the CMD_DONE flag after polling for command completion. This allows the interrupt handler to start another transfer when the CMD_DONE interrupt has not been disabled due to flow control.

[PATCH iwl-next v2 5/6] idpf: fix netdev Tx queue stop/wake

by Alexander Lobakin

From: Michal Kubiak <michal.kubiak(a)intel.com> netif_txq_maybe_stop() returns -1, 0, or 1, while idpf_tx_maybe_stop_common() says it returns 0 or -EBUSY. As a result, there sometimes are Tx queue timeout warnings despite that the queue is empty or there is at least enough space to restart it. Make idpf_tx_maybe_stop_common() inline and returning true or false, handling the return of netif_txq_maybe_stop() properly. Use a correct goto in idpf_tx_maybe_stop_splitq() to avoid stopping the queue or incrementing the stops counter twice.

[PATCH v2] f2fs: Do not check the FI_DIRTY_INODE flag when umounting a ro fs.

by Julian Sun

Hi, all. Recently syzbot reported a bug as following: kernel BUG at fs/f2fs/inode.c:896! CPU: 1 UID: 0 PID: 5217 Comm: syz-executor605 Not tainted 6.11.0-rc4-syzkaller-00033-g872cf28b8df9 #0 RIP: 0010:f2fs_evict_inode+0x1598/0x15c0 fs/f2fs/inode.c:896 Call Trace: <TASK> evict+0x532/0x950 fs/inode.c:704 dispose_list fs/inode.c:747 [inline] evict_inodes+0x5f9/0x690 fs/inode.c:797 generic_shutdown_super+0x9d/0x2d0 fs/super.c:627 kill_block_super+0x44/0x90 fs/super.c:1696 kill_f2fs_super+0x344/0x690 fs/f2fs/super.c:4898 deactivate_locked_super+0xc4/0x130 fs/super.c:473 cleanup_mnt+0x41f/0x4b0 fs/namespace.c:1373 task_work_run+0x24f/0x310 kernel/task_work.c:228 ptrace_notify+0x2d2/0x380 kernel/signal.c:2402 ptrace_report_syscall include/linux/ptrace.h:415 [inline] ptrace_report_syscall_exit include/linux/ptrace.h:477 [inline] syscall_exit_work+0xc6/0x190 kernel/entry/common.c:173 syscall_exit_to_user_mode_prepare kernel/entry/common.c:200 [inline] __syscall_exit_to_user_mode_work kernel/entry/common.c:205 [inline] syscall_exit_to_user_mode+0x279/0x370 kernel/entry/common.c:218 do_syscall_64+0x100/0x230 arch/x86/entry/common.c:89 entry_SYSCALL_64_after_hwframe+0x77/0x7f The syzbot constructed the following scenario: concurrently creating directories and setting the file system to read-only. In this case, while f2fs was making dir, the filesystem switched to readonly, and when it tried to clear the dirty flag, it triggered this code path: f2fs_mkdir()-> f2fs_sync_fs()->f2fs_write_checkpoint() ->f2fs_readonly(). This resulted FI_DIRTY_INODE flag not being cleared, which eventually led to a bug being triggered during the FI_DIRTY_INODE check in f2fs_evict_inode(). In this case, we cannot do anything further, so if filesystem is readonly, do not trigger the BUG. Instead, clean up resources to the best of our ability to prevent triggering subsequent resource leak checks. If there is anything important I'm missing, please let me know, thanks.

[PATCH 6.1.y] selftests: mptcp: join: cannot rm sf if closed

by Matthieu Baerts (NGI0)

commit e93681afcb96864ec26c3b2ce94008ce93577373 upstream. Thanks to the previous commit, the MPTCP subflows are now closed on both directions even when only the MPTCP path-manager of one peer asks for their closure. In the two tests modified here -- "userspace pm add & remove address" and "userspace pm create destroy subflow" -- one peer is controlled by the userspace PM, and the other one by the in-kernel PM. When the userspace PM sends a RM_ADDR notification, the in-kernel PM will automatically react by closing all subflows using this address. Now, thanks to the previous commit, the subflows are properly closed on both directions, the userspace PM can then no longer closes the same subflows if they are already closed. Before, it was OK to do that, because the subflows were still half-opened, still OK to send a RM_ADDR. In other words, thanks to the previous commit closing the subflows, an error will be returned to the userspace if it tries to close a subflow that has already been closed. So no need to run this command, which mean that the linked counters will then not be incremented. These tests are then no longer sending both a RM_ADDR, then closing the linked subflow just after. The test with the userspace PM on the server side is now removing one subflow linked to one address, then sending a RM_ADDR for another address. The test with the userspace PM on the client side is now only removing the subflow that was previously created.

When the worker is instructed to close the subflows that have been marked as closed, it might then try to close the initial subflow again. A consequence of that is that the SUB_CLOSED event can be seen twice: # ip mptcp endpoint 1.1.1.1 id 1 subflow dev eth0 2.2.2.2 id 2 subflow dev eth1 # ip mptcp monitor & [ CREATED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ ESTABLISHED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ SF_ESTABLISHED] remid=0 locid=2 saddr4=2.2.2.2 daddr4=9.9.9.9 # ip mptcp endpoint delete id 1 [ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 The first one is coming from mptcp_pm_nl_rm_subflow_received(), and the second one from __mptcp_close_subflow(). To avoid doing the post-closed processing twice, the subflow is now marked as closed the first time. Note that it is not enough to check if we are dealing with the first subflow and check its sk_state: the subflow might have been reset or closed before calling mptcp_close_ssk().

When an endpoint is being deleted, it is then important to check if its address is not linked to the initial subflow to send the right ID. If there was an endpoint linked to the initial subflow, msk's mpc_endpoint_id field will be set. We can then use this info when an endpoint is being removed to see if it is linked to the initial subflow. So now, the correct IDs are passed to mptcp_pm_nl_rm_addr_or_subflow(), it is no longer needed to use mptcp_local_id_match().

It is specific per connection. When a global endpoint is deleted and re-added later, it can have a different ID, but the kernel should still use the ID 0 if it corresponds to the initial address. This test validates this behaviour: the endpoint linked to the initial subflow is removed, and re-added with a different ID. Note that removing the initial subflow will not decrement the 'subflows' counters, which corresponds to the *additional* subflows. On the other hand, when the same endpoint is re-added, it will increment this counter, as it will be seen as an additional subflow this time.

With the dynamic debug feature, it is easy to enable all or some of them, and asks users to reproduce issues with extra debug. Many of these pr_debug() don't end with a new line, while no 'pr_cont()' are used in MPTCP code. So the goal was not to display multiple debug messages on one line: they were then not missing the '\n' on purpose. Not having the new line at the end causes these messages to be printed with a delay, when something else needs to be printed. This issue is not visible when many messages need to be printed, but it is annoying and confusing when only specific messages are expected, e.g. # echo "func mptcp_pm_add_addr_echoed +fmp" \ > /sys/kernel/debug/dynamic_debug/control # ./mptcp_join.sh "signal address"; \ echo "$(awk '{print $1}' /proc/uptime) - end"; \ sleep 5s; \ echo "$(awk '{print $1}' /proc/uptime) - restart"; \ ./mptcp_join.sh "signal address" 013 signal address (...) 10.75 - end 15.76 - restart 013 signal address [ 10.367935] mptcp:mptcp_pm_add_addr_echoed: MPTCP: msk=(...) (...) => a delay of 5 seconds: printed with a 10.36 ts, but after 'restart' which was printed at the 15.76 ts. The 'Fixes' tag here below points to the first pr_debug() used without '\n' in net/mptcp. This patch could be split in many small ones, with different Fixes tag, but it doesn't seem worth it, because it is easy to re-generate this patch with this simple 'sed' command: git grep -l pr_debug -- net/mptcp | xargs sed -i "s/$pr_debug(\".*[^n]$$\"[,)]$/\1\\\n\2/g" So in case of conflicts, simply drop the modifications, and launch this command.

If there are some, it will pick them, using their entry ID. It should set the ID 0 when using the endpoint corresponding to the initial subflow, it is a special case imposed by the MPTCP specs. Note that msk->mpc_endpoint_id might not be set when receiving the first ADD_ADDR from the server. So better to compare the addresses.

If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free. A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with.

In the two tests modified here -- "userspace pm add & remove address" and "userspace pm create destroy subflow" -- one peer is controlled by the userspace PM, and the other one by the in-kernel PM. When the userspace PM sends a RM_ADDR notification, the in-kernel PM will automatically react by closing all subflows using this address. Now, thanks to the previous commit, the subflows are properly closed on both directions, the userspace PM can then no longer closes the same subflows if they are already closed. Before, it was OK to do that, because the subflows were still half-opened, still OK to send a RM_ADDR. In other words, thanks to the previous commit closing the subflows, an error will be returned to the userspace if it tries to close a subflow that has already been closed. So no need to run this command, which mean that the linked counters will then not be incremented. These tests are then no longer sending both a RM_ADDR, then closing the linked subflow just after. The test with the userspace PM on the server side is now removing one subflow linked to one address, then sending a RM_ADDR for another address. The test with the userspace PM on the client side is now only removing the subflow that was previously created.

With the dynamic debug feature, it is easy to enable all or some of them, and asks users to reproduce issues with extra debug. Many of these pr_debug() don't end with a new line, while no 'pr_cont()' are used in MPTCP code. So the goal was not to display multiple debug messages on one line: they were then not missing the '\n' on purpose. Not having the new line at the end causes these messages to be printed with a delay, when something else needs to be printed. This issue is not visible when many messages need to be printed, but it is annoying and confusing when only specific messages are expected, e.g. # echo "func mptcp_pm_add_addr_echoed +fmp" \ > /sys/kernel/debug/dynamic_debug/control # ./mptcp_join.sh "signal address"; \ echo "$(awk '{print $1}' /proc/uptime) - end"; \ sleep 5s; \ echo "$(awk '{print $1}' /proc/uptime) - restart"; \ ./mptcp_join.sh "signal address" 013 signal address (...) 10.75 - end 15.76 - restart 013 signal address [ 10.367935] mptcp:mptcp_pm_add_addr_echoed: MPTCP: msk=(...) (...) => a delay of 5 seconds: printed with a 10.36 ts, but after 'restart' which was printed at the 15.76 ts. The 'Fixes' tag here below points to the first pr_debug() used without '\n' in net/mptcp. This patch could be split in many small ones, with different Fixes tag, but it doesn't seem worth it, because it is easy to re-generate this patch with this simple 'sed' command: git grep -l pr_debug -- net/mptcp | xargs sed -i "s/$pr_debug(\".*[^n]$$\"[,)]$/\1\\\n\2/g" So in case of conflicts, simply drop the modifications, and launch this command.

When the worker is instructed to close the subflows that have been marked as closed, it might then try to close the initial subflow again. A consequence of that is that the SUB_CLOSED event can be seen twice: # ip mptcp endpoint 1.1.1.1 id 1 subflow dev eth0 2.2.2.2 id 2 subflow dev eth1 # ip mptcp monitor & [ CREATED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ ESTABLISHED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ SF_ESTABLISHED] remid=0 locid=2 saddr4=2.2.2.2 daddr4=9.9.9.9 # ip mptcp endpoint delete id 1 [ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 [ SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9 The first one is coming from mptcp_pm_nl_rm_subflow_received(), and the second one from __mptcp_close_subflow(). To avoid doing the post-closed processing twice, the subflow is now marked as closed the first time. Note that it is not enough to check if we are dealing with the first subflow and check its sk_state: the subflow might have been reset or closed before calling mptcp_close_ssk().

When an endpoint is being deleted, it is then important to check if its address is not linked to the initial subflow to send the right ID. If there was an endpoint linked to the initial subflow, msk's mpc_endpoint_id field will be set. We can then use this info when an endpoint is being removed to see if it is linked to the initial subflow. So now, the correct IDs are passed to mptcp_pm_nl_rm_addr_or_subflow(), it is no longer needed to use mptcp_local_id_match().

[PATCH RFC] driver core: bus: Correct return value for storing bus attribute drivers_probe

[PATCH V4 net] net: mana: Fix error handling in mana_create_txq/rxq's NAPI cleanup

by Souradeep Chakrabarti

Currently napi_disable() gets called during rxq and txq cleanup, even before napi is enabled and hrtimer is initialized. It causes kernel panic. ? page_fault_oops+0x136/0x2b0 ? page_counter_cancel+0x2e/0x80 ? do_user_addr_fault+0x2f2/0x640 ? refill_obj_stock+0xc4/0x110 ? exc_page_fault+0x71/0x160 ? asm_exc_page_fault+0x27/0x30 ? __mmdrop+0x10/0x180 ? __mmdrop+0xec/0x180 ? hrtimer_active+0xd/0x50 hrtimer_try_to_cancel+0x2c/0xf0 hrtimer_cancel+0x15/0x30 napi_disable+0x65/0x90 mana_destroy_rxq+0x4c/0x2f0 mana_create_rxq.isra.0+0x56c/0x6d0 ? mana_uncfg_vport+0x50/0x50 mana_alloc_queues+0x21b/0x320 ? skb_dequeue+0x5f/0x80 Cc: stable(a)vger.kernel.org Fixes: e1b5683ff62e ("net: mana: Move NAPI from EQ to CQ") Signed-off-by: Souradeep Chakrabarti <schakrabarti(a)linux.microsoft.com> Reviewed-by: Haiyang Zhang <haiyangz(a)microsoft.com> Reviewed-by: Shradha Gupta <shradhagupta(a)linux.microsoft.com> --- V4 -> V3: Made napi_initialized from atomic_t to bool in txq, as per review comment.

[PATCH] drm: imx: ipuv3-plane: fix HDMI cannot work for odd screen resolutions

by Paul Pu

This changes the judgement of if needing to round up the width or not, from using the `dp_flow` to the plane's type. The `dp_flow` can be -22(-EINVAL) even the plane is a PRIMARY one. See `client_reg[]` in `ipu-common.c`. [ 0.605141] [drm:ipu_plane_init] channel 28, dp flow -22, possible_crtcs=0x0 Per the commit message in commit: 71f9fd5bcf09, using the plane type for judging if rounding up is needed is correct.

[PATCH v5.15] virtio_net: Fix napi_skb_cache_put warning

[PATCH v6.6] virtio_net: Fix napi_skb_cache_put warning

by Shivani Agarwal

From: Breno Leitao <leitao(a)debian.org> [ Upstream commit f8321fa75102246d7415a6af441872f6637c93ab ] After the commit bdacf3e34945 ("net: Use nested-BH locking for napi_alloc_cache.") was merged, the following warning began to appear: WARNING: CPU: 5 PID: 1 at net/core/skbuff.c:1451 napi_skb_cache_put+0x82/0x4b0 __warn+0x12f/0x340 napi_skb_cache_put+0x82/0x4b0 napi_skb_cache_put+0x82/0x4b0 report_bug+0x165/0x370 handle_bug+0x3d/0x80 exc_invalid_op+0x1a/0x50 asm_exc_invalid_op+0x1a/0x20 __free_old_xmit+0x1c8/0x510 napi_skb_cache_put+0x82/0x4b0 __free_old_xmit+0x1c8/0x510 __free_old_xmit+0x1c8/0x510 __pfx___free_old_xmit+0x10/0x10 The issue arises because virtio is assuming it's running in NAPI context even when it's not, such as in the netpoll case. To resolve this, modify virtnet_poll_tx() to only set NAPI when budget is available. Same for virtnet_poll_cleantx(), which always assumed that it was in a NAPI context.

[PATCH] net: drop bad gso csum_start and offset in virtio_net_hdr

by Denis Arefev

From: Willem de Bruijn <willemb(a)google.com> Tighten csum_start and csum_offset checks in virtio_net_hdr_to_skb for GSO packets. The function already checks that a checksum requested with VIRTIO_NET_HDR_F_NEEDS_CSUM is in skb linear. But for GSO packets this might not hold for segs after segmentation. Syzkaller demonstrated to reach this warning in skb_checksum_help offset = skb_checksum_start_offset(skb); ret = -EINVAL; if (WARN_ON_ONCE(offset >= skb_headlen(skb))) By injecting a TSO packet: WARNING: CPU: 1 PID: 3539 at net/core/dev.c:3284 skb_checksum_help+0x3d0/0x5b0 ip_do_fragment+0x209/0x1b20 net/ipv4/ip_output.c:774 ip_finish_output_gso net/ipv4/ip_output.c:279 [inline] __ip_finish_output+0x2bd/0x4b0 net/ipv4/ip_output.c:301 iptunnel_xmit+0x50c/0x930 net/ipv4/ip_tunnel_core.c:82 ip_tunnel_xmit+0x2296/0x2c70 net/ipv4/ip_tunnel.c:813 __gre_xmit net/ipv4/ip_gre.c:469 [inline] ipgre_xmit+0x759/0xa60 net/ipv4/ip_gre.c:661 __netdev_start_xmit include/linux/netdevice.h:4850 [inline] netdev_start_xmit include/linux/netdevice.h:4864 [inline] xmit_one net/core/dev.c:3595 [inline] dev_hard_start_xmit+0x261/0x8c0 net/core/dev.c:3611 __dev_queue_xmit+0x1b97/0x3c90 net/core/dev.c:4261 packet_snd net/packet/af_packet.c:3073 [inline] The geometry of the bad input packet at tcp_gso_segment: [ 52.003050][ T8403] skb len=12202 headroom=244 headlen=12093 tailroom=0 [ 52.003050][ T8403] mac=(168,24) mac_len=24 net=(192,52) trans=244 [ 52.003050][ T8403] shinfo(txflags=0 nr_frags=1 gso(size=1552 type=3 segs=0)) [ 52.003050][ T8403] csum(0x60000c7 start=199 offset=1536 ip_summed=3 complete_sw=0 valid=0 level=0) Mitigate with stricter input validation. csum_offset: for GSO packets, deduce the correct value from gso_type. This is already done for USO. Extend it to TSO. Let UFO be: udp[46]_ufo_fragment ignores these fields and always computes the checksum in software. csum_start: finding the real offset requires parsing to the transport header. Do not add a parser, use existing segmentation parsing. Thanks to SKB_GSO_DODGY, that also catches bad packets that are hw offloaded. Again test both TSO and USO. Do not test UFO for the above reason, and do not test UDP tunnel offload. GSO packet are almost always CHECKSUM_PARTIAL. USO packets may be CHECKSUM_NONE since commit 10154dbded6d6 ("udp: Allow GSO transmit from devices with no checksum offload"), but then still these fields are initialized correctly in udp4_hwcsum/udp6_hwcsum_outgoing. So no need to test for ip_summed == CHECKSUM_PARTIAL first. This revises an existing fix mentioned in the Fixes tag, which broke small packets with GSO offload, as detected by kselftests.

[merged mm-stable] mm-krealloc-consider-spare-memory-for-__gfp_zero.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm: krealloc: consider spare memory for __GFP_ZERO has been removed from the -mm tree. Its filename was mm-krealloc-consider-spare-memory-for-__gfp_zero.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Danilo Krummrich <dakr(a)kernel.org> Subject: mm: krealloc: consider spare memory for __GFP_ZERO Date: Tue, 13 Aug 2024 00:34:34 +0200 As long as krealloc() is called with __GFP_ZERO consistently, starting with the initial memory allocation, __GFP_ZERO should be fully honored. However, if for an existing allocation krealloc() is called with a decreased size, it is not ensured that the spare portion the allocation is zeroed. Thus, if krealloc() is subsequently called with a larger size again, __GFP_ZERO can't be fully honored, since we don't know the previous size, but only the bucket size. Example: buf = kzalloc(64, GFP_KERNEL); memset(buf, 0xff, 64); buf = krealloc(buf, 48, GFP_KERNEL | __GFP_ZERO); /* After this call the last 16 bytes are still 0xff. */ buf = krealloc(buf, 64, GFP_KERNEL | __GFP_ZERO); Fix this, by explicitly setting spare memory to zero, when shrinking an allocation with __GFP_ZERO flag set or init_on_alloc enabled.

[PATCH] drm: imx: ipuv3-plane: fix HDMI cannot work for odd screen resolutions

by Paul Pu

This changes the judgement of if needing to round up the width or not, from using the `dp_flow` to the plane's type. The `dp_flow` can be -22(-EINVAL) even the plane is a PRIMARY one. See `client_reg[]` in `ipu-common.c`. [ 0.605141] [drm:ipu_plane_init] channel 28, dp flow -22, possible_crtcs=0x0 Per the commit message in commit: 71f9fd5bcf09, using the plane type for judging if rounding up is needed is correct.

[PATCH] usb: gadget: dummy_hcd: execute hrtimer callback in softirq context

by andrey.konovalov＠linux.dev

From: Andrey Konovalov <andreyknvl(a)gmail.com> Commit a7f3813e589f ("usb: gadget: dummy_hcd: Switch to hrtimer transfer scheduler") switched dummy_hcd to use hrtimer and made the timer's callback be executed in the hardirq context. With that change, __usb_hcd_giveback_urb now gets executed in the hardirq context, which causes problems for KCOV and KMSAN. One problem is that KCOV now is unable to collect coverage from the USB code that gets executed from the dummy_hcd's timer callback, as KCOV cannot collect coverage in the hardirq context. Another problem is that the dummy_hcd hrtimer might get triggered in the middle of a softirq with KCOV remote coverage collection enabled, and that causes a WARNING in KCOV, as reported by syzbot. (I sent a separate patch to shut down this WARNING, but that doesn't fix the other two issues.) Finally, KMSAN appears to ignore tracking memory copying operations that happen in the hardirq context, which causes false positive kernel-infoleaks, as reported by syzbot. Change the hrtimer in dummy_hcd to execute the callback in the softirq context.

[merged mm-hotfixes-stable] mm-memcontrol-respect-zswapwriteback-setting-from-parent-cg-too.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/memcontrol: respect zswap.writeback setting from parent cg too has been removed from the -mm tree. Its filename was mm-memcontrol-respect-zswapwriteback-setting-from-parent-cg-too.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: Mike Yuan <me(a)yhndnzj.com> Subject: mm/memcontrol: respect zswap.writeback setting from parent cg too Date: Fri, 23 Aug 2024 16:27:06 +0000 Currently, the behavior of zswap.writeback wrt. the cgroup hierarchy seems a bit odd. Unlike zswap.max, it doesn't honor the value from parent cgroups. This surfaced when people tried to globally disable zswap writeback, i.e. reserve physical swap space only for hibernation [1] - disabling zswap.writeback only for the root cgroup results in subcgroups with zswap.writeback=1 still performing writeback. The inconsistency became more noticeable after I introduced the MemoryZSwapWriteback= systemd unit setting [2] for controlling the knob. The patch assumed that the kernel would enforce the value of parent cgroups. It could probably be workarounded from systemd's side, by going up the slice unit tree and inheriting the value. Yet I think it's more sensible to make it behave consistently with zswap.max and friends.

[PATCH] x86/topology: Tolerate lack of APIC when booting as Xen domU

by Ariadne Conill

Xen domU instances do not boot on x86 with ACPI enabled, so the entire ACPI subsystem is ultimately disabled. This causes acpi_mps_check() to trigger a warning that the ACPI MPS table is not present, which then disables APIC support on domU, breaking the CPU topology detection for all vCPUs other than the boot vCPU.

[PATCH] ALSA: hda/realtek: extend quirks for Clevo V5[46]0

by Marek Marczykowski-Górecki

The mic in those laptops suffers too high gain resulting in mostly (fan or else) noise being recorded. In addition to the existing fixup about mic detection, apply also limiting its boost. While at it, extend the quirk to also V5[46]0TNE models, which have the same issue.

linux-stable-rc.git: queue/6.1 is tracking v6.10 kernel

by Matthieu Baerts

Hi Sasha, I hope you are well! If I'm not mistaken, I think you are the person managing the script updating the 'queue/*' branches from the linux-stable-rc git tree, right? It looks like the branch for the v6.1 is in fact tracking the v6.10 kernel instead: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/… Are you the person who is able to fix that? If not, do you know who can fix that? These branches are really useful, not to have to apply patches from the 'stable-queue' tree. Thank you! I also just noticed that they are used by CIs, e.g. the one from Linaro: https://qa-reports.linaro.org/lkft/linux-stable-rc-queues-queue_6.1/ Cheers, Matt -- Sponsored by the NGI0 Core fund.

[PATCH v2] usb: typec: ucsi: Fix cable registration

The Cable PD Revision field in GET_CABLE_PROPERTY was introduced in UCSI v2.1, so adding check for that.

[PATCH 1/3] platform/x86: panasonic-laptop: Check minimum SQTY value

by Hans de Goede

The panasonic laptop code in various places uses the sinf array with index values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the sinf array is big enough. Check for a minimum SQTY value of SINF_CUR_BRIGHT to avoid out of bounds accesses of the sinf array. Note SQTY returning SINF_CUR_BRIGHT is ok because the driver adds one extra entry to the sinf array.

This will only work in parallel mode, where frstdata pin is set low after the 2nd sample read starts. For the serial mode, according to the datasheet, "The FRSTDATA output returns to a logic low following the 16th SCLK falling edge.", thus after the Xth pulse, X being the number of bits in a sample, the check will always be true, and the driver will not work at all in serial mode if frstdata(optional) is defined in the devicetree as it will reset the chip, and return -EIO every time read_sample is called. Hence, this check must be removed for serial mode.

[PATCH v2] usb: xhci: fixes lost of data for xHCI Cadence Controllers

by Pawel Laszczak

Stream endpoint can skip part of TD during next transfer initialization after beginning stopped during active stream data transfer. The Set TR Dequeue Pointer command does not clear all internal transfer-related variables that position stream endpoint on transfer ring. USB Controller stores all endpoint state information within RsvdO fields inside endpoint context structure. For stream endpoints, all relevant information regarding particular StreamID is stored within corresponding Stream Endpoint context. Whenever driver wants to stop stream endpoint traffic, it invokes Stop Endpoint command which forces the controller to dump all endpoint state-related variables into RsvdO spaces into endpoint context and stream endpoint context. Whenever driver wants to reinitialize endpoint starting point on Transfer Ring, it uses the Set TR Dequeue Pointer command to update dequeue pointer for particular stream in Stream Endpoint Context. When stream endpoint is forced to stop active transfer in the middle of TD, it dumps an information about TRB bytes left in RsvdO fields in Stream Endpoint Context which will be used in next transfer initialization to designate starting point for XDMA. This field is not cleared during Set TR Dequeue Pointer command which causes XDMA to skip over transfer ring and leads to data loss on stream pipe. Patch fixes this by clearing out all RsvdO fields before initializing new transfer via that StreamID. Field Rsvd0 is reserved field, so patch should not have impact for other xHCI controllers.

Date: Mon, 2 Sep 2024 11:08:44 +0800 During the mounting process, if journal_reset() fails because of too short journal, then lead to jbd2_journal_load() fails with NULL j_sb_buffer. Subsequently, ocfs2_journal_shutdown() calls jbd2_journal_flush()->jbd2_cleanup_journal_tail()-> __jbd2_update_log_tail()->jbd2_journal_update_sb_log_tail() ->lock_buffer(journal->j_sb_buffer), resulting in a null-pointer dereference error. To resolve this issue, we should check the JBD2_LOADED flag to ensure the journal was properly loaded. Additionally, use journal instead of osb->journal directly to simplify the code.

[PATCH RFC 0/8] extensible syscalls: CHECK_FIELDS to allow for easier feature detection

by Aleksa Sarai

This is something that I've been thinking about for a while. We had a discussion at LPC 2020 about this[1] but the proposals suggested there never materialised. In short, it is quite difficult for userspace to detect the feature capability of syscalls at runtime. This is something a lot of programs want to do, but they are forced to create elaborate scenarios to try to figure out if a feature is supported without causing damage to the system. For the vast majority of cases, each individual feature also needs to be tested individually (because syscall results are all-or-nothing), so testing even a single syscall's feature set can easily inflate the startup time of programs. This patchset implements the fairly minimal design I proposed in this talk[2] and in some old LKML threads (though I can't find the exact references ATM). The general flow looks like: 1. Userspace will indicate to the kernel that a syscall should a be no-op by setting the top bit of the extensible struct size argument. We will almost certainly never support exabyte sized structs, so the top bits are free for us to use as makeshift flag bits. This is preferable to using the per-syscall flag field inside the structure because seccomp can easily detect the bit in the flag and allow the probe or forcefully return -EEXTSYS_NOOP. 2. The kernel will then fill the provided structure with every valid bit pattern that the current kernel understands. For flags or other bitflag-like fields, this is the set of valid flags or bits. For pointer fields or fields that take an arbitrary value, the field has every bit set (0xFF... to fill the field) to indicate that any value is valid in the field. 3. The syscall then returns -EEXTSYS_NOOP which is an errno that will only ever be used for this purpose (so userspace can be sure that the request succeeded). On older kernels, the syscall will return a different error (usually -E2BIG or -EFAULT) and userspace can do their old-fashioned checks. 4. Userspace can then check which flags and fields are supported by looking at the fields in the returned structure. Flags are checked by doing an AND with the flags field, and field support can checked by comparing to 0. In principle you could just AND the entire structure if you wanted to do this check generically without caring about the structure contents (this is what libraries might consider doing). Userspace can even find out the internal kernel structure size by passing a PAGE_SIZE buffer and seeing how many bytes are non-zero. As with copy_struct_from_user(), this is designed to be forward- and backwards- compatible. This allows programas to get a one-shot understanding of what features a syscall supports without having to do any elaborate setups or tricks to detect support for destructive features. Flags can simply be ANDed to check if they are in the supported set, and fields can just be checked to see if they are non-zero. This patchset is IMHO the simplest way we can add the ability to introspect the feature set of extensible struct (copy_struct_from_user) syscalls. It doesn't preclude the chance of a more generic mechanism being added later. The intended way of using this interface to get feature information looks something like the following (imagine that openat2 has gained a new field and a new flag in the future): static bool openat2_no_automount_supported; static bool openat2_cwd_fd_supported; int check_openat2_support(void) { int err; struct open_how how = {}; err = openat2(AT_FDCWD, ".", &how, CHECK_FIELDS | sizeof(how)); assert(err < 0); switch (errno) { case EFAULT: case E2BIG: /* Old kernel... */ check_support_the_old_way(); break; case EEXTSYS_NOOP: openat2_no_automount_supported = (how.flags & RESOLVE_NO_AUTOMOUNT); openat2_cwd_fd_supported = (how.cwd_fd != 0); break; } } [1]: https://lwn.net/Articles/830666/ [2]: https://youtu.be/ggD-eb3yPVs Signed-off-by: Aleksa Sarai <cyphar(a)cyphar.com> --- Aleksa Sarai (8): uaccess: add copy_struct_to_user helper sched_getattr: port to copy_struct_to_user openat2: explicitly return -E2BIG for (usize > PAGE_SIZE) openat2: add CHECK_FIELDS flag to usize argument clone3: add CHECK_FIELDS flag to usize argument selftests: openat2: add 0xFF poisoned data after misaligned struct selftests: openat2: add CHECK_FIELDS selftests selftests: clone3: add CHECK_FIELDS selftests fs/open.c | 17 ++ include/linux/uaccess.h | 98 +++++++++ include/uapi/asm-generic/errno.h | 3 + include/uapi/linux/openat2.h | 2 + kernel/fork.c | 33 ++- kernel/sched/syscalls.c | 42 +--- tools/testing/selftests/clone3/.gitignore | 1 + tools/testing/selftests/clone3/Makefile | 2 +- .../testing/selftests/clone3/clone3_check_fields.c | 229 +++++++++++++++++++++ tools/testing/selftests/openat2/openat2_test.c | 126 +++++++++++- 10 files changed, 504 insertions(+), 49 deletions(-) --- base-commit: 431c1646e1f86b949fa3685efc50b660a364c2b6 change-id: 20240803-extensible-structs-check_fields-a47e94cef691 Best regards, -- Aleksa Sarai <cyphar(a)cyphar.com>

[PATCH] arm64: dts: mediatek: mt8186-corsola: Disable DPI display interface

by Chen-Yu Tsai

The DPI display interface feeds the external display pipeline. However the pipeline representation is currently incomplete. Efforts are still under way to come up with a way to represent the "creative" repurposing of the DP bridge chip's internal output mux, which is meant to support USB type-C orientation changes, to output to one of two type-C ports. Until that is finalized, the external display can't be fully described, and thus won't work. Even worse, the half complete graph potentially confuses the OS, breaking the internal display as well. Disable the external display interface across the whole Corsola family until the DP / USB Type-C muxing graph binding is ready.

So return -ETIME. } To fix this, introduce a 'prev' variable and check if 'now - prev' is larger than delta.

[PATCH] pinctrl: qcom: x1e80100: Bypass PDC wakeup parent for now

by Stephan Gerhold

On X1E80100, GPIO interrupts for wakeup-capable pins have been broken since the introduction of the pinctrl driver. This prevents keyboard and touchpad from working on most of the X1E laptops. So far we have worked around this by manually building a kernel with the "wakeup-parent" removed from the pinctrl node in the device tree, but we cannot expect all users to do that. Implement a similar workaround in the driver by clearing the wakeirq_map for X1E80100. This avoids using the PDC wakeup parent for all GPIOs and handles the interrupts directly in the pinctrl driver instead. The PDC driver needs additional changes to support X1E80100 properly. Adding a workaround separately first allows to land the necessary PDC changes through the normal release cycle, while still solving the more critical problem with keyboard and touchpad on the current stable kernel versions. Bypassing the PDC is enough for now, because we have not yet enabled the deep idle states where using the PDC becomes necessary.

The map itself is correct, so I just "clear" it by setting .nwakeirq_map to 0 for now.

Fwd: [PATCH 3/9] xfs: xfs_finobt_count_blocks() walks the wrong btree

by Anders Blomdell

Dave forgot to mark the original patch for stable, so after consulting with Dave, here it comes @Greg: you might want to add the patch to all versions that received 14dd46cf31f4 ("xfs: split xfs_inobt_init_cursor") (which I think is v6.9 and v6.10) /Anders -------- Forwarded Message -------- Subject: [PATCH 3/9] xfs: xfs_finobt_count_blocks() walks the wrong btree Date: Thu, 22 Aug 2024 16:59:33 -0700 From: Darrick J. Wong <djwong(a)kernel.org> To: djwong(a)kernel.org CC: Anders Blomdell <anders.blomdell(a)gmail.com>, Dave Chinner <dchinner(a)redhat.com>, Christoph Hellwig <hch(a)lst.de>, hch(a)lst.de, linux-xfs(a)vger.kernel.org From: Dave Chinner <dchinner(a)redhat.com> As a result of the factoring in commit 14dd46cf31f4 ("xfs: split xfs_inobt_init_cursor"), mount started taking a long time on a user's filesystem. For Anders, this made mount times regress from under a second to over 15 minutes for a filesystem with only 30 million inodes in it. Anders bisected it down to the above commit, but even then the bug was not obvious. In this commit, over 20 calls to xfs_inobt_init_cursor() were modified, and some we modified to call a new function named xfs_finobt_init_cursor(). If that takes you a moment to reread those function names to see what the rename was, then you have realised why this bug wasn't spotted during review. And it wasn't spotted on inspection even after the bisect pointed at this commit - a single missing "f" isn't the easiest thing for a human eye to notice.... The result is that xfs_finobt_count_blocks() now incorrectly calls xfs_inobt_init_cursor() so it is now walking the inobt instead of the finobt. Hence when there are lots of allocated inodes in a filesystem, mount takes a -long- time run because it now walks a massive allocated inode btrees instead of the small, nearly empty free inode btrees. It also means all the finobt space reservations are wrong, so mount could potentially given ENOSPC on kernel upgrade. In hindsight, commit 14dd46cf31f4 should have been two commits - the first to convert the finobt callers to the new API, the second to modify the xfs_inobt_init_cursor() API for the inobt callers. That would have made the bug very obvious during review.

[merged mm-stable] mm-hugetlb_vmemmap-batch-hvo-work-when-demoting.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/hugetlb_vmemmap: batch HVO work when demoting has been removed from the -mm tree. Its filename was mm-hugetlb_vmemmap-batch-hvo-work-when-demoting.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Yu Zhao <yuzhao(a)google.com> Subject: mm/hugetlb_vmemmap: batch HVO work when demoting Date: Mon, 12 Aug 2024 16:48:23 -0600 Batch the HVO work, including de-HVO of the source and HVO of the destination hugeTLB folios, to speed up demotion. After commit bd225530a4c7 ("mm/hugetlb_vmemmap: fix race with speculative PFN walkers"), each request of HVO or de-HVO, batched or not, invokes synchronize_rcu() once. For example, when not batched, demoting one 1GB hugeTLB folio to 512 2MB hugeTLB folios invokes synchronize_rcu() 513 times (1 de-HVO plus 512 HVO requests), whereas when batched, only twice (1 de-HVO plus 1 HVO request). And the performance difference between the two cases is significant, e.g., echo 2048kB >/sys/kernel/mm/hugepages/hugepages-1048576kB/demote_size time echo 100 >/sys/kernel/mm/hugepages/hugepages-1048576kB/demote Before this patch: real 8m58.158s user 0m0.009s sys 0m5.900s After this patch: real 0m0.900s user 0m0.000s sys 0m0.851s Note that this patch changes the behavior of the `demote` interface when de-HVO fails. Before, the interface aborts immediately upon failure; now, it tries to finish an entire batch, meaning it can make extra progress if the rest of the batch contains folios that do not need to de-HVO.

[merged mm-stable] mm-only-enforce-minimum-stack-gap-size-if-its-sensible.patch removed from -mm tree

The quilt patch titled Subject: mm: only enforce minimum stack gap size if it's sensible has been removed from the -mm tree. Its filename was mm-only-enforce-minimum-stack-gap-size-if-its-sensible.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Gow <davidgow(a)google.com> Subject: mm: only enforce minimum stack gap size if it's sensible Date: Sat, 3 Aug 2024 15:46:41 +0800 The generic mmap_base code tries to leave a gap between the top of the stack and the mmap base address, but enforces a minimum gap size (MIN_GAP) of 128MB, which is too large on some setups. In particular, on arm tasks without ADDR_LIMIT_32BIT, the STACK_TOP value is less than 128MB, so it's impossible to fit such a gap in. Only enforce this minimum if MIN_GAP < MAX_GAP, as we'd prefer to honour MAX_GAP, which is defined proportionally, so scales better and always leaves us with both _some_ stack space and some room for mmap. This fixes the usercopy KUnit test suite on 32-bit arm, as it doesn't set any personality flags so gets the default (in this case 26-bit) task size. This test can be run with: ./tools/testing/kunit/kunit.py run --arch arm usercopy --make_options LLVM=1 Link: https://lkml.kernel.org/r/20240803074642.1849623-2-davidgow@google.com Fixes: dba79c3df4a2 ("arm: use generic mmap top-down layout and brk randomization") Signed-off-by: David Gow <davidgow(a)google.com> Reviewed-by: Kees Cook <kees(a)kernel.org> Cc: Alexandre Ghiti <alex(a)ghiti.fr> Cc: Linus Walleij <linus.walleij(a)linaro.org> Cc: Luis Chamberlain <mcgrof(a)kernel.org> Cc: Mark Rutland <mark.rutland(a)arm.com> Cc: Russell King <linux(a)armlinux.org.uk> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/util.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/util.c~mm-only-enforce-minimum-stack-gap-size-if-its-sensible +++ a/mm/util.c @@ -463,7 +463,7 @@ static unsigned long mmap_base(unsigned if (gap + pad > gap) gap += pad; - if (gap < MIN_GAP) + if (gap < MIN_GAP && MIN_GAP < MAX_GAP) gap = MIN_GAP; else if (gap > MAX_GAP) gap = MAX_GAP; _ Patches currently in -mm which might be from davidgow(a)google.com are

This function is used to initialize module sections as well as core kernel sections, in which case the module parameter is set to NULL. This function has to be called even when CONFIG_MODULES=n to initialize core kernel allocation tag sections. When CONFIG_MODULES=n, this function is a NOP, which is wrong. This leads to /proc/allocinfo reported as empty. Fix this by making it independent of CONFIG_MODULES.

[Root Cause] 1) Each purge_list has the long list. The following shows the number of vmap_area is purged. crash> p vmap_nodes vmap_nodes = $27 = (struct vmap_node *) 0xff2de5a900100000 crash> vmap_node 0xff2de5a900100000 128 | grep nr_purged nr_purged = 663070 ... nr_purged = 821670 nr_purged = 692214 nr_purged = 726808 ... 2) atomic_long_sub() employs the 'lock' prefix to ensure the atomic operation when purging each vmap_area. However, the iteration is over 600000 vmap_area (See 'nr_purged' above). Here is objdump output: $ objdump -D vmlinux ffffffff813e8c80 <purge_vmap_node>: ... ffffffff813e8d70: f0 48 29 2d 68 0c bb lock sub %rbp,0x2bb0c68(%rip) ... Quote from "Instruction tables" pdf file [3]: Instructions with a LOCK prefix have a long latency that depends on cache organization and possibly RAM speed. If there are multiple processors or cores or direct memory access (DMA) devices, then all locked instructions will lock a cache line for exclusive access, which may involve RAM access. A LOCK prefix typically costs more than a hundred clock cycles, even on single-processor systems. That's why the latency of purge_vmap_node() dramatically increases on a many-core system: One core is busy on purging each vmap_area of the *long* purge_list and executing atomic_long_sub() for each vmap_area, while other cores free vmalloc allocations and execute atomic_long_add_return() in free_vmap_area_noflush(). [Solution] Employ a local variable to record the total purged pages, and execute atomic_long_sub() after the traversal of the purge_list is done. The experiment result shows the latency improvement is 99%.

If the lru has a large number of CMA folios consecutively, while the allocation type requested is not MIGRATE_MOVABLE, isolate_lru_folios can hold the lock for a very long time while it skips those. For FIO workload, ~150million order=0 folios were skipped to isolate a few ZONE_DMA folios [1]. This can cause lockups [1] and high memory pressure for extended periods of time [2]. Remove skipping CMA for MGLRU as well, as it was introduced in sort_folio for the same resaon as 5da226dbfce3a2f44978c2c7cf88166e69a6788b.

by Andrew Morton

The quilt patch titled Subject: mm/slub: add check for s->flags in the alloc_tagging_slab_free_hook has been removed from the -mm tree. Its filename was mm-slub-add-check-for-s-flags-in-the-alloc_tagging_slab_free_hook.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: Hao Ge <gehao(a)kylinos.cn> Subject: mm/slub: add check for s->flags in the alloc_tagging_slab_free_hook Date: Fri, 16 Aug 2024 09:33:36 +0800 When enable CONFIG_MEMCG & CONFIG_KFENCE & CONFIG_KMEMLEAK, the following warning always occurs,This is because the following call stack occurred: mem_pool_alloc kmem_cache_alloc_noprof slab_alloc_node kfence_alloc Once the kfence allocation is successful,slab->obj_exts will not be empty, because it has already been assigned a value in kfence_init_pool. Since in the prepare_slab_obj_exts_hook function,we perform a check for s->flags & (SLAB_NO_OBJ_EXT | SLAB_NOLEAKTRACE),the alloc_tag_add function will not be called as a result.Therefore,ref->ct remains NULL. However,when we call mem_pool_free,since obj_ext is not empty, it eventually leads to the alloc_tag_sub scenario being invoked. This is where the warning occurs.

For __GFP_NO_OBJ_EXT case,I didn't see the specific case where it's using kfence,so I won't add the corresponding check in alloc_tagging_slab_free_hook for now.

[merged mm-hotfixes-stable] nilfs2-fix-state-management-in-error-path-of-log-writing-function.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: nilfs2: fix state management in error path of log writing function has been removed from the -mm tree. Its filename was nilfs2-fix-state-management-in-error-path-of-log-writing-function.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: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> Subject: nilfs2: fix state management in error path of log writing function Date: Wed, 14 Aug 2024 19:11:19 +0900 After commit a694291a6211 ("nilfs2: separate wait function from nilfs_segctor_write") was applied, the log writing function nilfs_segctor_do_construct() was able to issue I/O requests continuously even if user data blocks were split into multiple logs across segments, but two potential flaws were introduced in its error handling. First, if nilfs_segctor_begin_construction() fails while creating the second or subsequent logs, the log writing function returns without calling nilfs_segctor_abort_construction(), so the writeback flag set on pages/folios will remain uncleared. This causes page cache operations to hang waiting for the writeback flag. For example, truncate_inode_pages_final(), which is called via nilfs_evict_inode() when an inode is evicted from memory, will hang. Second, the NILFS_I_COLLECTED flag set on normal inodes remain uncleared. As a result, if the next log write involves checkpoint creation, that's fine, but if a partial log write is performed that does not, inodes with NILFS_I_COLLECTED set are erroneously removed from the "sc_dirty_files" list, and their data and b-tree blocks may not be written to the device, corrupting the block mapping. Fix these issues by uniformly calling nilfs_segctor_abort_construction() on failure of each step in the loop in nilfs_segctor_do_construct(), having it clean up logs and segment usages according to progress, and correcting the conditions for calling nilfs_redirty_inodes() to ensure that the NILFS_I_COLLECTED flag is cleared.

It turned out that if data recovery was performed using partial logs created by dsync writes, but an error occurred before starting the log writer to create a recovered checkpoint, the inodes whose data had been recovered were left in the ns_dirty_files list of the nilfs object and were not freed. Fix this issue by cleaning up inodes that have read the recovery data if the recovery routine fails midway before the log writer starts.

So, accessing them requires mutual exclusion using the reader/writer semaphore "nilfs->ns_sem". Some sysfs attribute show methods read this superblock buffer without the necessary mutual exclusion, which can cause problems with pointer dereferencing and memory access, so fix it.

The quilt patch titled Subject: userfaultfd: fix checks for huge PMDs has been removed from the -mm tree. Its filename was userfaultfd-fix-checks-for-huge-pmds.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: Jann Horn <jannh(a)google.com> Subject: userfaultfd: fix checks for huge PMDs Date: Tue, 13 Aug 2024 22:25:21 +0200 Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2. The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version: 1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case). 2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr(). 3. On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong. I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2. This patch (of 2): This fixes two issues. I discovered that the following race can occur: mfill_atomic other thread ============ ============ <zap PMD> pmdp_get_lockless() [reads none pmd] <bail if trans_huge> <if none:> <pagefault creates transhuge zeropage> __pte_alloc [no-op] <zap PMD> <bail if pmd_trans_huge(*dst_pmd)> BUG_ON(pmd_none(*dst_pmd)) I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers. On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map[_lock]() to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table. The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs). On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table. Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different). If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table. As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway. Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.

This means that ucsi_unregister() is now called from atomic context, which isn't feasible as it's expecting a sleepable context. An effort is under way to get GLINK to invoke its callbacks in a sleepable context, but until then lets schedule the unregistration. A side effect of this is that ucsi_unregister() can now happen after the remote processor, and thereby the communication link with it, is gone. pmic_glink_send() is amended with a check to avoid the resulting NULL pointer dereference. This does however result in the user being informed about this error by the following entry in the kernel log: ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI write request: -5 Fixes: 9329933699b3 ("soc: qcom: pmic_glink: Make client-lock non-sleeping") Cc: stable(a)vger.kernel.org Reviewed-by: Heikki Krogerus <heikki.krogerus(a)linux.intel.com> Reviewed-by: Neil Armstrong <neil.armstrong(a)linaro.org> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> Tested-by: Amit Pundir <amit.pundir(a)linaro.org> Reviewed-by: Johan Hovold <johan+linaro(a)kernel.org> Tested-by: Johan Hovold <johan+linaro(a)kernel.org> Signed-off-by: Bjorn Andersson <quic_bjorande(a)quicinc.com> Link: https://lore.kernel.org/r/20240820-pmic-glink-v6-11-races-v3-2-eec53c750a04… Signed-off-by: Bjorn Andersson <andersson(a)kernel.org> diff --git a/drivers/soc/qcom/pmic_glink.c b/drivers/soc/qcom/pmic_glink.c index 53b176d04fbd..b218460219b7 100644 --- a/drivers/soc/qcom/pmic_glink.c +++ b/drivers/soc/qcom/pmic_glink.c @@ -112,8 +112,16 @@ EXPORT_SYMBOL_GPL(pmic_glink_client_register); int pmic_glink_send(struct pmic_glink_client *client, void *data, size_t len) { struct pmic_glink *pg = client->pg; + int ret; - return rpmsg_send(pg->ept, data, len); + mutex_lock(&pg->state_lock); + if (!pg->ept) + ret = -ECONNRESET; + else + ret = rpmsg_send(pg->ept, data, len); + mutex_unlock(&pg->state_lock); + + return ret; } EXPORT_SYMBOL_GPL(pmic_glink_send); diff --git a/drivers/usb/typec/ucsi/ucsi_glink.c b/drivers/usb/typec/ucsi/ucsi_glink.c index f6f4fae40399..6aace19d595b 100644 --- a/drivers/usb/typec/ucsi/ucsi_glink.c +++ b/drivers/usb/typec/ucsi/ucsi_glink.c @@ -68,6 +68,9 @@ struct pmic_glink_ucsi { struct work_struct notify_work; struct work_struct register_work; + spinlock_t state_lock; + bool ucsi_registered; + bool pd_running; u8 read_buf[UCSI_BUF_SIZE]; }; @@ -244,8 +247,20 @@ static void pmic_glink_ucsi_notify(struct work_struct *work) static void pmic_glink_ucsi_register(struct work_struct *work) { struct pmic_glink_ucsi *ucsi = container_of(work, struct pmic_glink_ucsi, register_work); + unsigned long flags; + bool pd_running; - ucsi_register(ucsi->ucsi); + spin_lock_irqsave(&ucsi->state_lock, flags); + pd_running = ucsi->pd_running; + spin_unlock_irqrestore(&ucsi->state_lock, flags); + + if (!ucsi->ucsi_registered && pd_running) { + ucsi_register(ucsi->ucsi); + ucsi->ucsi_registered = true; + } else if (ucsi->ucsi_registered && !pd_running) { + ucsi_unregister(ucsi->ucsi); + ucsi->ucsi_registered = false; + } } static void pmic_glink_ucsi_callback(const void *data, size_t len, void *priv) @@ -269,11 +284,12 @@ static void pmic_glink_ucsi_callback(const void *data, size_t len, void *priv) static void pmic_glink_ucsi_pdr_notify(void *priv, int state) { struct pmic_glink_ucsi *ucsi = priv; + unsigned long flags; - if (state == SERVREG_SERVICE_STATE_UP) - schedule_work(&ucsi->register_work); - else if (state == SERVREG_SERVICE_STATE_DOWN) - ucsi_unregister(ucsi->ucsi); + spin_lock_irqsave(&ucsi->state_lock, flags); + ucsi->pd_running = (state == SERVREG_SERVICE_STATE_UP); + spin_unlock_irqrestore(&ucsi->state_lock, flags); + schedule_work(&ucsi->register_work); } static void pmic_glink_ucsi_destroy(void *data) @@ -320,6 +336,7 @@ static int pmic_glink_ucsi_probe(struct auxiliary_device *adev, INIT_WORK(&ucsi->register_work, pmic_glink_ucsi_register); init_completion(&ucsi->read_ack); init_completion(&ucsi->write_ack); + spin_lock_init(&ucsi->state_lock); mutex_init(&ucsi->lock); ucsi->ucsi = ucsi_create(dev, &pmic_glink_ucsi_ops);

[git:media_stage/master] media: imx335: Fix reset-gpio handling

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: imx335: Fix reset-gpio handling Author: Umang Jain <umang.jain(a)ideasonboard.com> Date: Fri Aug 30 11:41:52 2024 +0530 Rectify the logical value of reset-gpio so that it is set to 0 (disabled) during power-on and to 1 (enabled) during power-off. Set the reset-gpio to GPIO_OUT_HIGH at initialization time to make sure it starts off in reset. Also drop the "Set XCLR" comment which is not-so-informative. The existing usage of imx335 had reset-gpios polarity inverted (GPIO_ACTIVE_HIGH) in their device-tree sources. With this patch included, those DTS will not be able to stream imx335 anymore. The reset-gpio polarity will need to be rectified in the device-tree sources as shown in [1] example, in order to get imx335 functional again (as it remains in reset prior to this fix).

[git:media_stage/master] media: ov5675: Fix power on/off delay timings

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: ov5675: Fix power on/off delay timings Author: Bryan O'Donoghue <bryan.odonoghue(a)linaro.org> Date: Sat Jul 13 23:33:29 2024 +0100 The ov5675 specification says that the gap between XSHUTDN deassert and the first I2C transaction should be a minimum of 8192 XVCLK cycles. Right now we use a usleep_rage() that gives a sleep time of between about 430 and 860 microseconds. On the Lenovo X13s we have observed that in about 1/20 cases the current timing is too tight and we start transacting before the ov5675's reset cycle completes, leading to I2C bus transaction failures. The reset racing is sometimes triggered at initial chip probe but, more usually on a subsequent power-off/power-on cycle e.g. [ 71.451662] ov5675 24-0010: failed to write reg 0x0103. error = -5 [ 71.451686] ov5675 24-0010: failed to set plls The current quiescence period we have is too tight. Instead of expressing the post reset delay in terms of the current XVCLK this patch converts the power-on and power-off delays to the maximum theoretical delay @ 6 MHz with an additional buffer. 1.365 milliseconds on the power-on path is 1.5 milliseconds with grace. 85.3 microseconds on the power-off path is 90 microseconds with grace.

[PATCH] s390/pci: follow alloc_pages in dma_map_ops name change

by Ariadne Conill

In linux-6.6.y commit 983e6b2636f0099dbac1874c9e885bbe1cf2df05, alloc_pages was renamed to alloc_pages_op, but this was not changed for the s390 PCI implementation, most likely due to upstream changes in the s390 PCI implementation which moved it to using the generic IOMMU implementation after Linux 6.6 was released.

This function is used to initialize module sections as well as core kernel sections, in which case the module parameter is set to NULL. This function has to be called even when CONFIG_MODULES=n to initialize core kernel allocation tag sections. When CONFIG_MODULES=n, this function is a NOP, which is wrong. This leads to /proc/allocinfo reported as empty. Fix this by making it independent of CONFIG_MODULES.

[Root Cause] 1) Each purge_list has the long list. The following shows the number of vmap_area is purged. crash> p vmap_nodes vmap_nodes = $27 = (struct vmap_node *) 0xff2de5a900100000 crash> vmap_node 0xff2de5a900100000 128 | grep nr_purged nr_purged = 663070 ... nr_purged = 821670 nr_purged = 692214 nr_purged = 726808 ... 2) atomic_long_sub() employs the 'lock' prefix to ensure the atomic operation when purging each vmap_area. However, the iteration is over 600000 vmap_area (See 'nr_purged' above). Here is objdump output: $ objdump -D vmlinux ffffffff813e8c80 <purge_vmap_node>: ... ffffffff813e8d70: f0 48 29 2d 68 0c bb lock sub %rbp,0x2bb0c68(%rip) ... Quote from "Instruction tables" pdf file [3]: Instructions with a LOCK prefix have a long latency that depends on cache organization and possibly RAM speed. If there are multiple processors or cores or direct memory access (DMA) devices, then all locked instructions will lock a cache line for exclusive access, which may involve RAM access. A LOCK prefix typically costs more than a hundred clock cycles, even on single-processor systems. That's why the latency of purge_vmap_node() dramatically increases on a many-core system: One core is busy on purging each vmap_area of the *long* purge_list and executing atomic_long_sub() for each vmap_area, while other cores free vmalloc allocations and execute atomic_long_add_return() in free_vmap_area_noflush().

[PATCH] dma-buf: heaps: Fix off-by-one in CMA heap fault handler

by T.J. Mercier

Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps: Don't track CMA dma-buf pages under RssFile") it was possible to obtain a mapping larger than the buffer size via mremap and bypass the overflow check in dma_buf_mmap_internal. When using such a mapping to attempt to fault past the end of the buffer, the CMA heap fault handler also checks the fault offset against the buffer size, but gets the boundary wrong by 1. Fix the boundary check so that we don't read off the end of the pages array and insert an arbitrary page in the mapping.

[PATCH 5.10/5.15] net:rds: Fix possible deadlock in rds_message_put

by gerben＠altlinux.org

From: Allison Henderson <allison.henderson(a)oracle.com> commit f1acf1ac84d2ae97b7889b87223c1064df850069 upstream. Functions rds_still_queued and rds_clear_recv_queue lock a given socket in order to safely iterate over the incoming rds messages. However calling rds_inc_put while under this lock creates a potential deadlock. rds_inc_put may eventually call rds_message_purge, which will lock m_rs_lock. This is the incorrect locking order since m_rs_lock is meant to be locked before the socket. To fix this, we move the message item to a local list or variable that wont need rs_recv_lock protection. Then we can safely call rds_inc_put on any item stored locally after rs_recv_lock is released.

[PATCH v5.10-v5.15] cgroup/cpuset: Prevent UAF in proc_cpuset_show()

by Shivani Agarwal

From: Chen Ridong <chenridong(a)huawei.com> [ Upstream commit 1be59c97c83ccd67a519d8a49486b3a8a73ca28a ] An UAF can happen when /proc/cpuset is read as reported in [1]. This can be reproduced by the following methods: 1.add an mdelay(1000) before acquiring the cgroup_lock In the cgroup_path_ns function. 2.$cat /proc/<pid>/cpuset repeatly. 3.$mount -t cgroup -o cpuset cpuset /sys/fs/cgroup/cpuset/ $umount /sys/fs/cgroup/cpuset/ repeatly. The race that cause this bug can be shown as below: (umount) | (cat /proc/<pid>/cpuset) css_release | proc_cpuset_show css_release_work_fn | css = task_get_css(tsk, cpuset_cgrp_id); css_free_rwork_fn | cgroup_path_ns(css->cgroup, ...); cgroup_destroy_root | mutex_lock(&cgroup_mutex); rebind_subsystems | cgroup_free_root | | // cgrp was freed, UAF | cgroup_path_ns_locked(cgrp,..); When the cpuset is initialized, the root node top_cpuset.css.cgrp will point to &cgrp_dfl_root.cgrp. In cgroup v1, the mount operation will allocate cgroup_root, and top_cpuset.css.cgrp will point to the allocated &cgroup_root.cgrp. When the umount operation is executed, top_cpuset.css.cgrp will be rebound to &cgrp_dfl_root.cgrp. The problem is that when rebinding to cgrp_dfl_root, there are cases where the cgroup_root allocated by setting up the root for cgroup v1 is cached. This could lead to a Use-After-Free (UAF) if it is subsequently freed. The descendant cgroups of cgroup v1 can only be freed after the css is released. However, the css of the root will never be released, yet the cgroup_root should be freed when it is unmounted. This means that obtaining a reference to the css of the root does not guarantee that css.cgrp->root will not be freed. Fix this problem by using rcu_read_lock in proc_cpuset_show(). As cgroup_root is kfree_rcu after commit d23b5c577715 ("cgroup: Make operations on the cgroup root_list RCU safe"), css->cgroup won't be freed during the critical section. To call cgroup_path_ns_locked, css_set_lock is needed, so it is safe to replace task_get_css with task_css.

[PATCH] drm/sti: avoid potential dereference of error pointers in sti_gdp_atomic_check

by Ma Ke

The return value of drm_atomic_get_crtc_state() needs to be checked. To avoid use of error pointer 'crtc_state' in case of the failure.

The file meta data would have a ref count that is set when the file is created and would be decremented and freed after the last user that opened the file closed it. When the file meta data was to be freed, it would set a flag (EVENT_FILE_FL_FREED) to denote that the file is freed, and any new references made (like new opens or reads) would fail as it is marked freed. This allowed other meta data to be freed after this flag was set (under the event_mutex). All the files that were dynamically created in the events directory had a pointer to the file meta data and would call event_release() when the last reference to the user space file was closed. This would be the time that it is safe to free the file meta data. A shortcut was made for the "format" file. It's i_private would point to the "call" entry directly and not point to the file's meta data. This is because all format files are the same for the same "call", so it was thought there was no reason to differentiate them. The other files maintain state (like the "enable", "trigger", etc). But this meant if the file were to disappear, the "format" file would be unaware of it. This caused a race that could be trigger via the user_events test (that would create dynamic events and free them), and running a loop that would read the user_events format files: In one console run: # cd tools/testing/selftests/user_events # while true; do ./ftrace_test; done And in another console run: # cd /sys/kernel/tracing/ # while true; do cat events/user_events/__test_event/format; done 2>/dev/null With KASAN memory checking, it would trigger a use-after-free bug report (which was a real bug). This was because the format file was not checking the file's meta data flag "EVENT_FILE_FL_FREED", so it would access the event that the file meta data pointed to after the event was freed. After inspection, there are other locations that were found to not check the EVENT_FILE_FL_FREED flag when accessing the trace_event_file. Add a new helper function: event_file_file() that will make sure that the event_mutex is held, and will return NULL if the trace_event_file has the EVENT_FILE_FL_FREED flag set. Have the first reference of the struct file pointer use event_file_file() and check for NULL. Later uses can still use the event_file_data() helper function if the event_mutex is still held and was not released since the event_file_file() call.

Or in other words, the maximum difference between the first ant the last timestamp can be 4096 ticks or 4.096 seconds. This results in a maximum value for y2 of: 0x12FBECA00, that overflows 32bits. y2 = (u32)ktime_to_ns(ktime_sub(last->host_time, first->host_time)) + y1; Extend the size of y2 to u64 to support all its values.
