[v6.7][PATCH 00/23] eventfs: Linus's updates for 6.7

by Steven Rostedt

This is a backport of all the work that lead up to the work that Linus made on eventfs. I trust Linus's version more so than the versions in 6.6 and 6.7. There may be plenty of hidden issues due to the design. This is the update for 6.7. It includes Linus's updates as well as all the patches leading up to them. I ran these through my full test suite that I use before sending anyting to Linus, althouh I did not run my "bisect" test that walks through the patches. The tests were just run on the end result. I'm currently running my 6.6 version through my tests. Erick Archer (1): eventfs: Use kcalloc() instead of kzalloc() Linus Torvalds (7): tracefs: remove stale 'update_gid' code eventfs: Initialize the tracefs inode properly tracefs: Avoid using the ei->dentry pointer unnecessarily tracefs: dentry lookup crapectomy eventfs: Remove unused d_parent pointer field eventfs: Clean up dentry ops and add revalidate function eventfs: Get rid of dentry pointers without refcounts Steven Rostedt (Google) (15): eventfs: Remove "lookup" parameter from create_dir/file_dentry() eventfs: Stop using dcache_readdir() for getdents() tracefs/eventfs: Use root and instance inodes as default ownership eventfs: Have eventfs_iterate() stop immediately if ei->is_freed is set eventfs: Do ctx->pos update for all iterations in eventfs_iterate() eventfs: Read ei->entries before ei->children in eventfs_iterate() eventfs: Shortcut eventfs_iterate() by skipping entries already read eventfs: Have the inodes all for files and directories all be the same eventfs: Do not create dentries nor inodes in iterate_shared eventfs: Save directory inodes in the eventfs_inode structure tracefs: Zero out the tracefs_inode when allocating it eventfs: Warn if an eventfs_inode is freed without is_freed being set eventfs: Restructure eventfs_inode structure to be more condensed eventfs: Remove fsnotify*() functions from lookup() eventfs: Keep all directory links at 1 ---- fs/tracefs/event_inode.c | 905 ++++++++++++++++------------------------------- fs/tracefs/inode.c | 286 +++++++-------- fs/tracefs/internal.h | 48 ++- 3 files changed, 451 insertions(+), 788 deletions(-)

[PATCH v2] mtd: rawnand: marvell: fix layouts

by Elad Nachman

From: Elad Nachman <enachman(a)marvell.com> The check in nand_base.c, nand_scan_tail() : has the following code: (ecc->steps * ecc->size != mtd->writesize) which fails for some NAND chips. Remove ECC entries in this driver which are not integral multiplications, and adjust the number of chunks for entries which fails the above calculation so it will calculate correctly (this was previously done automatically before the check and was removed in a later commit).

[git:media_stage/master] media: xc4000: Fix atomicity violation in xc4000_get_frequency

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: xc4000: Fix atomicity violation in xc4000_get_frequency Author: Gui-Dong Han <2045gemini(a)gmail.com> Date: Fri Dec 22 13:50:30 2023 +0800 In xc4000_get_frequency(): *freq = priv->freq_hz + priv->freq_offset; The code accesses priv->freq_hz and priv->freq_offset without holding any lock. In xc4000_set_params(): // Code that updates priv->freq_hz and priv->freq_offset ... xc4000_get_frequency() and xc4000_set_params() may execute concurrently, risking inconsistent reads of priv->freq_hz and priv->freq_offset. Since these related data may update during reading, it can result in incorrect frequency calculation, leading to atomicity violations. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 6.2. To address this issue, it is proposed to add a mutex lock pair in xc4000_get_frequency() to ensure atomicity. With this patch applied, our tool no longer reports the possible bug, with the kernel configuration allyesconfig for x86_64. Due to the lack of associated hardware, we cannot test the patch in runtime testing, and just verify it according to the code logic.

S/PDIF not detected anymore / regression on recent kernel 6.7 ?

by Serge SIMON

Dear Kernel maintainers, I think i'm encountering (for the first time in years !) a regression with the "6.7.arch3-1" kernel (whereas no issues with "6.6.10.arch1-1", on which i reverted). I'm running a (up-to-date, and non-LTS) ARCHLINUX desktop, on a ASUS B560-I motherboard, with 3 monitors (attached to a 4-HDMI outputs card), plus an audio S/PDIF optic output at motherboard level. With the latest kernel, the S/PIDF optic output of the motherboard is NOT detected anymore (and i haven't been able to see / find anything in the logs at quick glance, neither journalctl -xe nor dmesg). Once reverted to 6.6.10, everything is fine again. For example, in a working situation (6.6.10), i have : cat /proc/asound/pcm 00-00: ALC1220 Analog : ALC1220 Analog : playback 1 : capture 1 00-01: ALC1220 Digital : ALC1220 Digital : playback 1 00-02: ALC1220 Alt Analog : ALC1220 Alt Analog : capture 1 01-03: HDMI 0 : HDMI 0 : playback 1 01-07: HDMI 1 : HDMI 1 : playback 1 01-08: HDMI 2 : HDMI 2 : playback 1 01-09: HDMI 3 : HDMI 3 : playback 1 Whereas while on the latest 6.7 kernel, i only had the 4 HDMI lines (linked to a NVIDIA T600 card, with 4 HDMI outputs) and not the three first ones (attached to the motherboard). (of course i did several tests with 6.7, reboot, ... without any changes) Any idea ? Best regards -- Serge.

[PATCH RFC v2 8/8] m68k: Move signal frame following exception on 68020/030

by Michael Schmitz

From: Finn Thain <fthain(a)linux-m68k.org> On 68030/020, an instruction such as, moveml %a2-%a3/%a5,%sp@- may cause a stack page fault during instruction execution (i.e. not at an instruction boundary) and produce a format 0xB exception frame. In this situation, the value of USP will be unreliable. If a signal is to be delivered following the exception, this USP value is used to calculate the location for a signal frame. This can result in a corrupted user stack. The corruption was detected in dash (actually in glibc) where it showed up as an intermittent "stack smashing detected" message and crash following signal delivery for SIGCHLD. It was hard to reproduce that failure because delivery of the signal raced with the page fault and because the kernel places an unpredictable gap of up to 7 bytes between the USP and the signal frame. A format 0xB exception frame can be produced by a bus error or an address error. The 68030 Users Manual says that address errors occur immediately upon detection during instruction prefetch. The instruction pipeline allows prefetch to overlap with other instructions, which means an address error can arise during the execution of a different instruction. So it seems likely that this patch may help in the address error case also.

[PATCH RFC v2 1/8] m68k/mm: Adjust VM area to be unmapped by gap size for __iounmap()

by Michael Schmitz

If 020/030 support is enabled, get_io_area() leaves an IO_SIZE gap between mappings which is added to the vm_struct representing the mapping. __ioremap() uses the actual requested size (after alignment), while __iounmap() is passed the size from the vm_struct. On 020/030, early termination descriptors are used to set up mappings of extent 'size', which are validated on unmapping. The unmapped gap of size IO_SIZE defeats the sanity check of the pmd tables, causing __iounmap() to loop forever on 030. On 040/060, unmapping of page table entries does not check for a valid mapping, so the umapping loop always completes there. Adjust size to be unmapped by the gap that had been added in the vm_struct prior. This fixes the hang in atari_platform_init() reported a long time ago, and a similar one reported by Finn recently (addressed by removing ioremap() use from the SWIM driver. Tested on my Falcon in 030 mode - untested but should work the same on 040/060 (the extra page tables cleared there would never have been set up anyway).

[PATCH net,v2] hv_netvsc: Register VF in netvsc_probe if NET_DEVICE_REGISTER missed

by Shradha Gupta

If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER handler cannot perform VF register successfully as the register call is received before netvsc_probe is finished. This is because we register register_netdevice_notifier() very early( even before vmbus_driver_register()).

[PATCH] IB/hfi1: Fix sdma.h tx->num_descs off-by-one error (take two)

Unfortunately the commit `fd8958efe877` introduced another error causing the `descs` array to overflow. This reults in further crashes easily reproducible by `sendmsg` system call.

Nilfs2 itself does not use end_buffer_async_write(). But, the async_write flag is now used as a marker by commit 7f42ec394156 ("nilfs2: fix issue with race condition of competition between segments for dirty blocks") as a means of resolving double list insertion of dirty blocks in nilfs_lookup_dirty_data_buffers() and nilfs_lookup_node_buffers() and the resulting crash. This modification is safe as long as it is used for file data and b-tree node blocks where the page caches are independent. However, it was irrelevant and redundant to also introduce async_write for segment summary and super root blocks that share buffers with the backing device. This led to the possibility that the BUG_ON check in end_buffer_async_write would fail as described above, if independent writebacks of the backing device occurred in parallel. The use of async_write for segment summary buffers has already been removed in a previous change. Fix this issue by removing the manipulation of the async_write flag for the remaining super root block buffer.

The following is a failing example: Error: #26 btf Error: #26/174 btf/BTF ID Error: #26/174 btf/BTF ID btf_raw_create:PASS:check 0 nsec btf_raw_create:PASS:check 0 nsec test_btf_id:PASS:check 0 nsec ... test_btf_id:PASS:check 0 nsec test_btf_id:FAIL:check BTF lingersdo_test_get_info:FAIL:check failed: -1 The test tries to prove a btf_id not available after the map is closed. But btf_id is freed only after workqueue and a rcu grace period, compared to previous case just after a rcu grade period. Depending on system workload, workqueue could take quite some time to execute function bpf_map_free_deferred() which may cause the test failure. Instead of adding arbitrary delays, let us remove the logic to check btf_id availability after map is closed.

[PATCH 5.15 6.1] gve: Fix use-after-free vulnerability

by Praveen Kaligineedi

From: Bailey Forrest <bcf(a)google.com> Call skb_shinfo() after gve_prep_tso() on DQO TX path. gve_prep_tso() calls skb_cow_head(), which may reallocate shinfo causing a use after free. This bug was unintentionally fixed by 'a6fb8d5a8b69 ("gve: Tx path for DQO-QPL")' while adding DQO-QPL format support in 6.6. That patch is not appropriate for stable releases.

[PATCH 6.1.y and 6.6.y] LoongArch/smp: Call rcutree_report_cpu_starting() at tlb_init()

by Huacai Chen

Machines which have more than 8 nodes fail to boot SMP after commit a2ccf46333d7b2cf96 ("LoongArch/smp: Call rcutree_report_cpu_starting() earlier"). Because such machines use tlb-based per-cpu base address rather than dmw-based per-cpu base address, resulting per-cpu variables can only be accessed after tlb_init(). But rcutree_report_cpu_starting() is now called before tlb_init() and accesses per-cpu variables indeed. Since the original patch want to avoid the lockdep warning caused by page allocation in tlb_init(), we can move rcutree_report_cpu_starting() to tlb_init() where after tlb exception configuration but before page allocation.

Re: Patch "i2c: rk3x: Adjust mask/value offset for i2c2 on rv1126" has been added to the 6.1-stable tree

Hi, This patch should not be added to 6.1 stable since support for the Rockchip rv1126 SoC was only added later around 6.3.

[PATCH ] mm/damon/sysfs-schemes: fix wrong DAMOS tried regions update timeout setup

by SeongJae Park

DAMON sysfs interface's update_schemes_tried_regions command has a timeout of two apply intervals of the DAMOS scheme. Having zero value DAMOS scheme apply interval means it will use the aggregation interval as the value. However, the timeout setup logic is mistakenly using the sampling interval insted of the aggregartion interval for the case. This could cause earlier-than-expected timeout of the command. Fix it.

[PATCH AUTOSEL 4.19 1/5] wifi: cfg80211: fix missing interfaces when dumping

by Sasha Levin

From: Michal Kazior <michal(a)plume.com> [ Upstream commit a6e4f85d3820d00694ed10f581f4c650445dbcda ] The nl80211_dump_interface() supports resumption in case nl80211_send_iface() doesn't have the resources to complete its work.

[PATCH v2 1/5] fuse: Fix VM_MAYSHARE and direct_io_allow_mmap

by Bernd Schubert

There were multiple issues with direct_io_allow_mmap: - fuse_link_write_file() was missing, resulting in warnings in fuse_write_file_get() and EIO from msync() - "vma->vm_ops = &fuse_file_vm_ops" was not set, but especially fuse_page_mkwrite is needed. The semantics of invalidate_inode_pages2() is so far not clearly defined in fuse_file_mmap. It dates back to commit 3121bfe76311 ("fuse: fix "direct_io" private mmap") Though, as direct_io_allow_mmap is a new feature, that was for MAP_PRIVATE only. As invalidate_inode_pages2() is calling into fuse_launder_folio() and writes out dirty pages, it should be safe to call invalidate_inode_pages2 for MAP_PRIVATE and MAP_SHARED as well.

While migrate_pages_batch() locks a folio and waits for the writeback to complete, the log writer thread that should bring the writeback to completion picks up the folio being written back in nilfs_lookup_dirty_data_buffers() that it calls for subsequent log creation and was trying to lock the folio. Thus causing a deadlock. In the first place, it is unexpected that folios/pages in the middle of writeback will be updated and become dirty. Nilfs2 adds a checksum to verify the validity of the log being written and uses it for recovery at mount, so data changes during writeback are suppressed. Since this is broken, an unclean shutdown could potentially cause recovery to fail. Investigation revealed that the root cause is that the wait for writeback completion in nilfs_page_mkwrite() is conditional, and if the backing device does not require stable writes, data may be modified without waiting. Fix these issues by making nilfs_page_mkwrite() wait for writeback to finish regardless of the stable write requirement of the backing device.

[PATCH regression fix 0/2] Input: atkbd - Fix Dell XPS 13 line suspend/resume regression

by Hans de Goede

Hi Dmitry, There have been multiple reports that the keyboard on Dell XPS 13 9350 / 9360 / 9370 models has stopped working after a suspend/resume after the merging of commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in translated mode"). See the 4 closes tags in the first patch for 4 reports of this. I have been working with the first reporter on resolving this and testing on his Dell XPS 13 9360 confirms that these patches fix things. Unfortunately the commit causing the issue has also been picked up by multiple stable kernel series now. Can you please send these fixes to Linus ASAP, so that they can also be backported to the stable series ASAP ? Alternatively we could revert the commit causing this, but that commit is know to fix issues on a whole bunch of other laptops so I would rather not revert it. Regards, Hans Hans de Goede (2): Input: atkbd - Skip ATKBD_CMD_SETLEDS when skipping ATKBD_CMD_GETID Input: atkbd - Do not skip atkbd_deactivate() when skipping ATKBD_CMD_GETID drivers/input/keyboard/atkbd.c | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) -- 2.43.0

[PATCH v5.10.y] netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval()

by Ajay Kaher

From: Dan Carpenter <dan.carpenter(a)linaro.org> commit c301f0981fdd3fd1ffac6836b423c4d7a8e0eb63 upstream. The problem is in nft_byteorder_eval() where we are iterating through a loop and writing to dst[0], dst[1], dst[2] and so on... On each iteration we are writing 8 bytes. But dst[] is an array of u32 so each element only has space for 4 bytes. That means that every iteration overwrites part of the previous element. I spotted this bug while reviewing commit caf3ef7468f7 ("netfilter: nf_tables: prevent OOB access in nft_byteorder_eval") which is a related issue. I think that the reason we have not detected this bug in testing is that most of time we only write one element.

[for-linus][PATCH 13/13] eventfs: Keep all directory links at 1

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> The directory link count in eventfs was somewhat bogus. It was only being updated when a directory child was being looked up and not on creation. One solution would be to update in get_attr() the link count by iterating the ei->children list and then adding 2. But that could slow down simple stat() calls, especially if it's done on all directories in eventfs. Another solution would be to add a parent pointer to the eventfs_inode and keep track of the number of sub directories it has on creation. But this adds overhead for something not really worthwhile. The solution decided upon is to keep all directory links in eventfs as 1. This tells user space not to rely on the hard links of directories. Which in this case it shouldn't.

[for-linus][PATCH 09/13] tracing/timerlat: Move hrtimer_init to timerlat_fd open()

by Steven Rostedt

[for-linus][PATCH 08/13] eventfs: Get rid of dentry pointers without refcounts

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> The eventfs inode had pointers to dentries (and child dentries) without actually holding a refcount on said pointer. That is fundamentally broken, and while eventfs tried to then maintain coherence with dentries going away by hooking into the '.d_iput' callback, that doesn't actually work since it's not ordered wrt lookups. There were two reasonms why eventfs tried to keep a pointer to a dentry: - the creation of a 'events' directory would actually have a stable dentry pointer that it created with tracefs_start_creating(). And it needed that dentry when tearing it all down again in eventfs_remove_events_dir(). This use is actually ok, because the special top-level events directory dentries are actually stable, not just a temporary cache of the eventfs data structures. - the 'eventfs_inode' (aka ei) needs to stay around as long as there are dentries that refer to it. It then used these dentry pointers as a replacement for doing reference counting: it would try to make sure that there was only ever one dentry associated with an event_inode, and keep a child dentry array around to see which dentries might still refer to the parent ei. This gets rid of the invalid dentry pointer use, and renames the one valid case to a different name to make it clear that it's not just any random dentry. The magic child dentry array that is kind of a "reverse reference list" is simply replaced by having child dentries take a ref to the ei. As does the directory dentries. That makes the broken use case go away.

[for-linus][PATCH 07/13] eventfs: Clean up dentry ops and add revalidate function

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> In order for the dentries to stay up-to-date with the eventfs changes, just add a 'd_revalidate' function that checks the 'is_freed' bit. Also, clean up the dentry release to actually use d_release() rather than the slightly odd d_iput() function. We don't care about the inode, all we want to do is to get rid of the refcount to the eventfs data added by dentry->d_fsdata. It would probably be cleaner to make eventfs its own filesystem, or at least set its own dentry ops when looking up eventfs files. But as it is, only eventfs dentries use d_fsdata, so we don't really need to split these things up by use. Another thing that might be worth doing is to make all eventfs lookups mark their dentries as not worth caching. We could do that with d_delete(), but the DCACHE_DONTCACHE flag would likely be even better. As it is, the dentries are all freeable, but they only tend to get freed at memory pressure rather than more proactively. But that's a separate issue.

[for-linus][PATCH 05/13] tracefs: dentry lookup crapectomy

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> The dentry lookup for eventfs files was very broken, and had lots of signs of the old situation where the filesystem names were all created statically in the dentry tree, rather than being looked up dynamically based on the eventfs data structures. You could see it in the naming - how it claimed to "create" dentries rather than just look up the dentries that were given it. You could see it in various nonsensical and very incorrect operations, like using "simple_lookup()" on the dentries that were passed in, which only results in those dentries becoming negative dentries. Which meant that any other lookup would possibly return ENOENT if it saw that negative dentry before the data was then later filled in. You could see it in the immense amount of nonsensical code that didn't actually just do lookups.

[for-linus][PATCH 04/13] tracefs: Avoid using the ei->dentry pointer unnecessarily

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> The eventfs_find_events() code tries to walk up the tree to find the event directory that a dentry belongs to, in order to then find the eventfs inode that is associated with that event directory. However, it uses an odd combination of walking the dentry parent, looking up the eventfs inode associated with that, and then looking up the dentry from there. Repeat. But the code shouldn't have back-pointers to dentries in the first place, and it should just walk the dentry parenthood chain directly. Similarly, 'set_top_events_ownership()' looks up the dentry from the eventfs inode, but the only reason it wants a dentry is to look up the superblock in order to look up the root dentry.

[for-linus][PATCH 02/13] tracefs: Zero out the tracefs_inode when allocating it

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> eventfs uses the tracefs_inode and assumes that it's already initialized to zero. That is, it doesn't set fields to zero (like ti->private) after getting its tracefs_inode. This causes bugs due to stale values. Just initialize the entire structure to zero on allocation so there isn't any more surprises. This is a partial fix to access to ti->private. The assignment still needs to be made before the dentry is instantiated.

[for-linus][PATCH 01/13] ring-buffer: Clean ring_buffer_poll_wait() error return

by Steven Rostedt

From: Vincent Donnefort <vdonnefort(a)google.com> The return type for ring_buffer_poll_wait() is __poll_t. This is behind the scenes an unsigned where we can set event bits. In case of a non-allocated CPU, we do return instead -EINVAL (0xffffffea). Lucky us, this ends up setting few error bits (EPOLLERR | EPOLLHUP | EPOLLNVAL), so user-space at least is aware something went wrong. Nonetheless, this is an incorrect code. Replace that -EINVAL with a proper EPOLLERR to clean that output. As this doesn't change the behaviour, there's no need to treat this change as a bug fix.

[PATCH] tracing/timerlat: Move hrtimer_init to timerlat_fd open()

by Daniel Bristot de Oliveira

Currently, the timerlat's hrtimer is initialized at the first read of timerlat_fd, and destroyed at close(). It works, but it causes an error if the user program open() and close() the file without reading. Move hrtimer_init to timerlat_fd open() to avoid this problem. No functional changes.

[PATCH net 0/9] mptcp: fixes for recent issues reported by CI's

by Matthieu Baerts (NGI0)

This series of 9 patches fixes issues mostly identified by CI's not managed by the MPTCP maintainers. Thank you Linero (LKFT) and Netdev maintainers (NIPA) for running our kunit and selftests tests! For the first patch, it took a bit of time to identify the root cause. Some MPTCP Join selftest subtests have been "flaky", mostly in slow environments. It appears to be due to the use of a TCP-specific helper on an MPTCP socket. A fix for kernels >= v5.15. Patches 2 to 4 add missing kernel config to support NetFilter tables needed for IPTables commands. These kconfigs are usually enabled in default configurations, but apparently not for all architectures. Patches 2 and 3 can be backported up to v5.11 and the 4th one up to v5.19. Patch 5 increases the time limit for MPTCP selftests. It appears that many CI's execute tests in a VM without acceleration supports, e.g. QEmu without KVM. As a result, the tests take longer. Plus, there are more and more tests. This patch modifies the timeout added in v5.18. Patch 6 reduces the maximum rate and delay of the different links in some Simult Flows selftest subtests. The goal is to let slow VMs reach the maximum speed. The original rate was introduced in v5.11. Patch 7 lets CI changing the prefix of the subtests titles, to be able to run the same selftest multiple times with different parameters. With different titles, tests will be considered as different and not override previous results as it is the case with some CI envs. Subtests have been introduced in v6.6. Patch 8 and 9 make some MPTCP Join selftest subtests quicker by stopping the transfer when the expected events have been seen. Patch 8 can be backported up to v6.5.

[PATCH V2 net] hv_netvsc: Fix race condition between netvsc_probe and netvsc_remove

by Souradeep Chakrabarti

In commit ac5047671758 ("hv_netvsc: Disable NAPI before closing the VMBus channel"), napi_disable was getting called for all channels, including all subchannels without confirming if they are enabled or not. This caused hv_netvsc getting hung at napi_disable, when netvsc_probe() has finished running but nvdev->subchan_work has not started yet. netvsc_subchan_work() -> rndis_set_subchannel() has not created the sub-channels and because of that netvsc_sc_open() is not running. netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for which netvsc_subchan_work did not run. netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI cannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear the NAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the opposite. Now during netvsc_device_remove(), when napi_disable is called for those subchannels, napi_disable gets stuck on infinite msleep. This fix addresses this problem by ensuring that napi_disable() is not getting called for non-enabled NAPI struct.

[PATCH 4/6] eventfs: Keep all directory links at 1

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> The directory link count in eventfs was somewhat bogus. It was only being updated when a directory child was being looked up and not on creation. One solution would be to update in get_attr() the link count by iterating the ei->children list and then adding 2. But that could slow down simple stat() calls, especially if it's done on all directories in eventfs. Another solution would be to add a parent pointer to the eventfs_inode and keep track of the number of sub directories it has on creation. But this adds overhead for something not really worthwhile. The solution decided upon is to keep all directory links in eventfs as 1. This tells user space not to rely on the hard links of directories. Which in this case it shouldn't.

[PATCH] tty: fix atomicity violation in n_tty_read

by Gui-Dong Han

In n_tty_read(): if (packet && tty->link->ctrl.pktstatus) { ... spin_lock_irq(&tty->link->ctrl.lock); cs = tty->link->ctrl.pktstatus; tty->link->ctrl.pktstatus = 0; spin_unlock_irq(&tty->link->ctrl.lock); *kb++ = cs; ... In n_tty_read() function, there is a potential atomicity violation issue. The tty->link->ctrl.pktstatus might be set to 0 after being checked, which could lead to incorrect values in the kernel space buffer pointer (kb/kbuf). The check if (packet && tty->link->ctrl.pktstatus) occurs outside the spin_lock_irq(&tty->link->ctrl.lock) block. This may lead to tty->link->ctrl.pktstatus being altered between the check and the lock, causing *kb++ = cs; to be assigned with a zero pktstatus value. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 5.17. To resolve this atomicity issue, it is suggested to move the condition check if (packet && tty->link->ctrl.pktstatus) inside the spin_lock block. With this patch applied, our tool no longer reports the bug, with the kernel configuration allyesconfig for x86_64. Due to the absence of the requisite hardware, we are unable to conduct runtime testing of the patch. Therefore, our verification is solely based on code logic analysis.

[PATCH] nfsd: fix RELEASE_LOCKOWNER

by Chuck Lever

From: NeilBrown <neilb(a)suse.de> [ Upstream commit edcf9725150e42beeca42d085149f4c88fa97afd ] The test on so_count in nfsd4_release_lockowner() is nonsense and harmful. Revert to using check_for_locks(), changing that to not sleep. First: harmful. As is documented in the kdoc comment for nfsd4_release_lockowner(), the test on so_count can transiently return a false positive resulting in a return of NFS4ERR_LOCKS_HELD when in fact no locks are held. This is clearly a protocol violation and with the Linux NFS client it can cause incorrect behaviour. If RELEASE_LOCKOWNER is sent while some other thread is still processing a LOCK request which failed because, at the time that request was received, the given owner held a conflicting lock, then the nfsd thread processing that LOCK request can hold a reference (conflock) to the lock owner that causes nfsd4_release_lockowner() to return an incorrect error. The Linux NFS client ignores that NFS4ERR_LOCKS_HELD error because it never sends NFS4_RELEASE_LOCKOWNER without first releasing any locks, so it knows that the error is impossible. It assumes the lock owner was in fact released so it feels free to use the same lock owner identifier in some later locking request. When it does reuse a lock owner identifier for which a previous RELEASE failed, it will naturally use a lock_seqid of zero. However the server, which didn't release the lock owner, will expect a larger lock_seqid and so will respond with NFS4ERR_BAD_SEQID. So clearly it is harmful to allow a false positive, which testing so_count allows. The test is nonsense because ... well... it doesn't mean anything. so_count is the sum of three different counts. 1/ the set of states listed on so_stateids 2/ the set of active vfs locks owned by any of those states 3/ various transient counts such as for conflicting locks. When it is tested against '2' it is clear that one of these is the transient reference obtained by find_lockowner_str_locked(). It is not clear what the other one is expected to be. In practice, the count is often 2 because there is precisely one state on so_stateids. If there were more, this would fail. In my testing I see two circumstances when RELEASE_LOCKOWNER is called. In one case, CLOSE is called before RELEASE_LOCKOWNER. That results in all the lock states being removed, and so the lockowner being discarded (it is removed when there are no more references which usually happens when the lock state is discarded). When nfsd4_release_lockowner() finds that the lock owner doesn't exist, it returns success. The other case shows an so_count of '2' and precisely one state listed in so_stateid. It appears that the Linux client uses a separate lock owner for each file resulting in one lock state per lock owner, so this test on '2' is safe. For another client it might not be safe. So this patch changes check_for_locks() to use the (newish) find_any_file_locked() so that it doesn't take a reference on the nfs4_file and so never calls nfsd_file_put(), and so never sleeps. With this check is it safe to restore the use of check_for_locks() rather than testing so_count against the mysterious '2'.

[PATCH] hv_netvsc:Register VF in netvsc_probe if NET_DEVICE_REGISTER missed

by Shradha Gupta

If hv_netvsc driver is removed and reloaded, the NET_DEVICE_REGISTER handler cannot perform VF register successfully as the register call is received before netvsc_probe is finished.

[PATCH v2 4/7] tracefs: dentry lookup crapectomy

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> The dentry lookup for eventfs files was very broken, and had lots of signs of the old situation where the filesystem names were all created statically in the dentry tree, rather than being looked up dynamically based on the eventfs data structures. You could see it in the naming - how it claimed to "create" dentries rather than just look up the dentries that were given it. You could see it in various nonsensical and very incorrect operations, like using "simple_lookup()" on the dentries that were passed in, which only results in those dentries becoming negative dentries. Which meant that any other lookup would possibly return ENOENT if it saw that negative dentry before the data was then later filled in. You could see it in the immense amount of nonsensical code that didn't actually just do lookups.

[PATCH] HID: wacom: generic: Avoid reporting a serial of '0' to userspace

by Tobita, Tatsunosuke

From: Jason Gerecke <killertofu(a)gmail.com> The xf86-input-wacom driver does not treat '0' as a valid serial number and will drop any input report which contains an MSC_SERIAL = 0 event. The kernel driver already takes care to avoid sending any MSC_SERIAL event if the value of serial[0] == 0 (which is the case for devices that don't actually report a serial number), but this is not quite sufficient. Only the lower 32 bits of the serial get reported to userspace, so if this portion of the serial is zero then there can still be problems. This commit allows the driver to report either the lower 32 bits if they are non-zero or the upper 32 bits otherwise.

[PATCH net v2] net: dsa: mv88e6xxx: Fix failed probe due to unsupported C45 reads

by Andrew Lunn

Not all mv88e6xxx device support C45 read/write operations. Those which do not return -EOPNOTSUPP. However, when phylib scans the bus, it considers this fatal, and the probe of the MDIO bus fails, which in term causes the mv88e6xxx probe as a whole to fail. When there is no device on the bus for a given address, the pull up resistor on the data line results in the read returning 0xffff. The phylib core code understands this when scanning for devices on the bus. C45 allows multiple devices to be supported at one address, so phylib will perform a few reads at each address, so although thought not the most efficient solution, it is a way to avoid fatal errors. Make use of this as a minimal fix for stable to fix the probing problems. Follow up patches will rework how C45 operates to make it similar to C22 which considers -ENODEV as a none-fatal, and swap mv88e6xxx to using this.

[PATCH] binder: signal epoll threads of self-work

by Carlos Llamas

In (e)poll mode, threads often depend on I/O events to determine when data is ready for consumption. Within binder, a thread may initiate a command via BINDER_WRITE_READ without a read buffer and then make use of epoll_wait() or similar to consume any responses afterwards. It is then crucial that epoll threads are signaled via wakeup when they queue their own work. Otherwise, they risk waiting indefinitely for an event leaving their work unhandled. What is worse, subsequent commands won't trigger a wakeup either as the thread has pending work.

[PATCH 16/21] drm/amd/display: Update phantom pipe enable / disable sequence

by Hamza Mahfooz

From: Alvin Lee <alvin.lee2(a)amd.com> Previously we would call apply_ctx_to_hw to enable and disable phantom pipes. However, apply_ctx_to_hw can potentially update non-phantom pipes as well which is undesired. Instead of calling apply_ctx_to_hw as a whole, call the relevant helpers for each phantom pipe when enabling / disabling which will avoid us modifying hardware state for non-phantom pipes unknowingly. The use case is for an FRL display where FRL_Update is requested by the display. In this case link_state_valid flag is cleared in a passive callback thread and should be handled in the next stream / link update. However, due to the call to apply_ctx_to_hw for the phantom pipes during a flip, the main pipes were modified outside of the desired sequence (driver does not handle link_state_valid = 0 on flips).

[PATCH 05/21] drm/amd/display: Add more checks for exiting idle in DC

by Hamza Mahfooz

From: Nicholas Kazlauskas <nicholas.kazlauskas(a)amd.com> [Why] Any interface that touches registers needs to wake up the system. [How] Add a new interface dc_exit_ips_for_hw_access that wraps the check for IPS support and insert it into the public DC interfaces that touch registers. We don't re-enter, since we expect that the enter/exit to have been done on the DM side.

[PATCH 03/21] drm/amd/display: set odm_combine_policy based on context in dcn32 resource

by Hamza Mahfooz

From: Wenjing Liu <wenjing.liu(a)amd.com> [why] When populating dml pipes, odm combine policy should be assigned based on the pipe topology of the context passed in. DML pipes could be repopulated multiple times during single validate bandwidth attempt. We need to make sure that whenever we repopulate the dml pipes it is always aligned with the updated context. There is a case where DML pipes get repopulated during FPO optimization after ODM combine policy is changed. Since in the current code we reinitlaize ODM combine policy, even though the current context has ODM combine enabled, we overwrite it despite the pipes are already split. This causes DML to think that MPC combine is used so we mistakenly enable MPC combine because we apply pipe split with ODM combine policy reset. This issue doesn't impact non windowed MPO with ODM case because the legacy policy has restricted use cases. We don't encounter the case where both ODM and FPO optimizations are enabled together. So we decide to leave it as is because it is about to be replaced anyway.

[PATCH v2 7/7] eventfs: Get rid of dentry pointers without refcounts

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> The eventfs inode had pointers to dentries (and child dentries) without actually holding a refcount on said pointer. That is fundamentally broken, and while eventfs tried to then maintain coherence with dentries going away by hooking into the '.d_iput' callback, that doesn't actually work since it's not ordered wrt lookups. There were two reasonms why eventfs tried to keep a pointer to a dentry: - the creation of a 'events' directory would actually have a stable dentry pointer that it created with tracefs_start_creating(). And it needed that dentry when tearing it all down again in eventfs_remove_events_dir(). This use is actually ok, because the special top-level events directory dentries are actually stable, not just a temporary cache of the eventfs data structures. - the 'eventfs_inode' (aka ei) needs to stay around as long as there are dentries that refer to it. It then used these dentry pointers as a replacement for doing reference counting: it would try to make sure that there was only ever one dentry associated with an event_inode, and keep a child dentry array around to see which dentries might still refer to the parent ei. This gets rid of the invalid dentry pointer use, and renames the one valid case to a different name to make it clear that it's not just any random dentry. The magic child dentry array that is kind of a "reverse reference list" is simply replaced by having child dentries take a ref to the ei. As does the directory dentries. That makes the broken use case go away.

[PATCH v2 6/7] eventfs: Clean up dentry ops and add revalidate function

by Steven Rostedt

From: Linus Torvalds <torvalds(a)linux-foundation.org> In order for the dentries to stay up-to-date with the eventfs changes, just add a 'd_revalidate' function that checks the 'is_freed' bit. Also, clean up the dentry release to actually use d_release() rather than the slightly odd d_iput() function. We don't care about the inode, all we want to do is to get rid of the refcount to the eventfs data added by dentry->d_fsdata. It would probably be cleaner to make eventfs its own filesystem, or at least set its own dentry ops when looking up eventfs files. But as it is, only eventfs dentries use d_fsdata, so we don't really need to split these things up by use. Another thing that might be worth doing is to make all eventfs lookups mark their dentries as not worth caching. We could do that with d_delete(), but the DCACHE_DONTCACHE flag would likely be even better. As it is, the dentries are all freeable, but they only tend to get freed at memory pressure rather than more proactively. But that's a separate issue.

From: Linus Torvalds <torvalds(a)linux-foundation.org> The eventfs_find_events() code tries to walk up the tree to find the event directory that a dentry belongs to, in order to then find the eventfs inode that is associated with that event directory. However, it uses an odd combination of walking the dentry parent, looking up the eventfs inode associated with that, and then looking up the dentry from there. Repeat. But the code shouldn't have back-pointers to dentries in the first place, and it should just walk the dentry parenthood chain directly. Similarly, 'set_top_events_ownership()' looks up the dentry from the eventfs inode, but the only reason it wants a dentry is to look up the superblock in order to look up the root dentry. But it already has the real filesystem inode, which has that same superblock pointer. So just pass in the superblock pointer using the information that's already there, instead of looking up extraneous data that is irrelevant.

[PATCH v2 1/7] tracefs: Zero out the tracefs_inode when allocating it

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> eventfs uses the tracefs_inode and assumes that it's already initialized to zero. That is, it doesn't set fields to zero (like ti->private) after getting its tracefs_inode. This causes bugs due to stale values. Just initialize the entire structure to zero on allocation so there isn't any more surprises. This is a partial fix to access to ti->private. The assignment still needs to be made before the dentry is instantiated.

[REGRESSION] boot fails for EFI boot stub loaded by u-boot

by Ben Schneider

Hi Ard, I have an ESPRESSObin Ultra (aarch64) that uses U-Boot as its bootloader. It shipped from the manufacturer with with v5.10, and I've been trying to upgrade. U-Boot supports booting Image directly via EFI (https://u-boot.readthedocs.io/en/latest/usage/cmd/bootefi.html), and I have been using it that way to successfully boot the system up to and including v6.0.19. However, v6.1 and v6.5 kernels fail to boot. When booting successfully, the following messages are displayed: EFI stub: Booting Linux Kernel...EFI stub: ERROR: FIRMWARE BUG: efi_loaded_image_t::image_base has bogus value EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary EFI stub: Using DTB from configuration table EFI stub: ERROR: Failed to install memreserve config table! EFI stub: Exiting boot services... [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] I suspect many of the above error messages are simply attributable to using U-Boot to load an EFI stub and can be safely ignored given that the system boots and runs fine. When boot fails (v6.5), the following messages are displayed: EFI stub: Booting Linux Kernel... EFI stub: ERROR: FIRMWARE BUG: efi_loaded_image_t::image_base has bogus value EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary EFI stub: ERROR: Failed to install memreserve config table! EFI stub: Using DTB from configuration table EFI stub: Exiting boot services... EFI stub: ERROR: Unable to construct new device tree. EFI stub: ERROR: Failed to update FDT and exit boot services In case it's relevant, the device tree for this device is arch/arm64/boot/marvell/armada-3720-espressobin-ultra.dts Hopefully I've reported this in the correct place or that the information provided is sufficient to get it where it needs to be. Let me know if there is additional information I can provide. I am also able to use the device to test. Sincerely, Ben Schneider #regzbot introduced v6.0..v6.1

[PATCH] x86/cpu/intel: Detect TME keyid bits before setting MTRR mask registers

by Paolo Bonzini

MKTME repurposes the high bit of physical address to key id for encryption key and, even though MAXPHYADDR in CPUID[0x80000008] remains the same, the valid bits in the MTRR mask register are based on the reduced number of physical address bits. detect_tme() in arch/x86/kernel/cpu/intel.c detects TME and subtracts it from the total usable physical bits, but it is called too late. Move the call to early_init_intel() so that it is called in setup_arch(), before MTRRs are setup. This fixes boot on some TDX-enabled systems which until now only worked with "disable_mtrr_cleanup". Without the patch, the values written to the MTRRs mask registers were 52-bit wide (e.g. 0x000fffff_80000800) and the writes failed; with the patch, the values are 46-bit wide, which matches the reduced MAXPHYADDR that is shown in /proc/cpuinfo.

[PATCH v2 0/3] HID: bpf: couple of upstream fixes

by Benjamin Tissoires

Hi, This is the v2 of this series of HID-BPF fixes. I have forgotten to include a Fixes tag in the first patch and got a review from Andrii on patch 2. And this first patch made me realize that something was fishy in the refcount of the hid devices. I was not crashing the system even if I accessed the struct hid_device after hid_destroy_device() was called, which was suspicious to say the least. So after some debugging I found the culprit and realized that I had a pretty nice memleak as soon as one HID-BPF program was attached to a HID device. The good thing though is that this ref count prevents a crash in case a HID-BPF program attempts to access a removed HID device when hid_bpf_allocate_context() has been called but not yet released. Anyway, for reference, the cover letter of v1: --- Hi, these are a couple of fixes for hid-bpf. The first one should probably go in ASAP, after the reviews, and the second one is nice to have and doesn't hurt much. Thanks Dan for finding out the issue with bpf_prog_get() Cheers, Benjamin To: Jiri Kosina <jikos(a)kernel.org> To: Benjamin Tissoires <benjamin.tissoires(a)redhat.com> To: Dan Carpenter <dan.carpenter(a)linaro.org> To: Daniel Borkmann <daniel(a)iogearbox.net> To: Andrii Nakryiko <andrii.nakryiko(a)gmail.com> Cc: <linux-input(a)vger.kernel.org> Cc: <linux-kernel(a)vger.kernel.org> Cc: <bpf(a)vger.kernel.org> Signed-off-by: Benjamin Tissoires <bentiss(a)kernel.org> --- Changes in v2: - add Fixes tags - handled Andrii review (use of __bpf_kfunc_start/end_defs()) - new patch to fetch ref counting of struct hid_device - Link to v1: https://lore.kernel.org/r/20240123-b4-hid-bpf-fixes-v1-0-aa1fac734377@kerne… --- Benjamin Tissoires (3): HID: bpf: remove double fdget() HID: bpf: actually free hdev memory after attaching a HID-BPF program HID: bpf: use __bpf_kfunc instead of noinline drivers/hid/bpf/hid_bpf_dispatch.c | 101 ++++++++++++++++++++++++++---------- drivers/hid/bpf/hid_bpf_dispatch.h | 4 +- drivers/hid/bpf/hid_bpf_jmp_table.c | 39 +++++++------- include/linux/hid_bpf.h | 11 ---- 4 files changed, 95 insertions(+), 60 deletions(-) --- base-commit: fef018d8199661962b5fc0f0d1501caa54b2b533 change-id: 20240123-b4-hid-bpf-fixes-662908fe2234 Best regards, -- Benjamin Tissoires <bentiss(a)kernel.org>

[PATCH] irqchip/gic-v3-its: Restore quirk probing for ACPI-based systems

by Marc Zyngier

While refactoring the way the ITSs are probed, the handling of quirks applicable to ACPI-based platforms was lost. As a result, systems such as HIP07 lose their GICv4 functionnality, and some other may even fail to boot, unless they are configured to boot with DT. Move the enabling of quirks into its_probe_one(), making it common to all firmware implementations.

Because such machines use tlb-based per-cpu base address rather than dmw-based per-cpu base address, resulting per-cpu variables can only be accessed after tlb_init(). But rcutree_report_cpu_starting() is now called before tlb_init() and accesses per-cpu variables indeed. Since the original patch want to avoid the lockdep warning caused by page allocation in tlb_init(), we can move rcutree_report_cpu_starting() to tlb_init() where after tlb exception configuration but before page allocation.

+ fshugetlb-fix-null-pointer-dereference-in-hugetlbs_fill_super.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: fs,hugetlb: fix NULL pointer dereference in hugetlbs_fill_super has been added to the -mm mm-hotfixes-unstable branch. Its filename is fshugetlb-fix-null-pointer-dereference-in-hugetlbs_fill_super.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Oscar Salvador <osalvador(a)suse.de> Subject: fs,hugetlb: fix NULL pointer dereference in hugetlbs_fill_super Date: Tue, 30 Jan 2024 22:04:18 +0100 When configuring a hugetlb filesystem via the fsconfig() syscall, there is a possible NULL dereference in hugetlbfs_fill_super() caused by assigning NULL to ctx->hstate in hugetlbfs_parse_param() when the requested pagesize is non valid. E.g: Taking the following steps: fd = fsopen("hugetlbfs", FSOPEN_CLOEXEC); fsconfig(fd, FSCONFIG_SET_STRING, "pagesize", "1024", 0); fsconfig(fd, FSCONFIG_CMD_CREATE, NULL, NULL, 0); Given that the requested "pagesize" is invalid, ctxt->hstate will be replaced with NULL, losing its previous value, and we will print an error: ... ... case Opt_pagesize: ps = memparse(param->string, &rest); ctx->hstate = h; if (!ctx->hstate) { pr_err("Unsupported page size %lu MB\n", ps / SZ_1M); return -EINVAL; } return 0; ... ... This is a problem because later on, we will dereference ctxt->hstate in hugetlbfs_fill_super() ... ... sb->s_blocksize = huge_page_size(ctx->hstate); ... ... Causing below Oops. Fix this by replacing cxt->hstate value only when then pagesize is known to be valid. kernel: hugetlbfs: Unsupported page size 0 MB kernel: BUG: kernel NULL pointer dereference, address: 0000000000000028 kernel: #PF: supervisor read access in kernel mode kernel: #PF: error_code(0x0000) - not-present page kernel: PGD 800000010f66c067 P4D 800000010f66c067 PUD 1b22f8067 PMD 0 kernel: Oops: 0000 [#1] PREEMPT SMP PTI kernel: CPU: 4 PID: 5659 Comm: syscall Tainted: G E 6.8.0-rc2-default+ #22 5a47c3fef76212addcc6eb71344aabc35190ae8f kernel: Hardware name: Intel Corp.

[PATCH v2] rpm-pkg: simplify installkernel %post

by Jose Ignacio Tornos Martinez

A new installkernel application is now included in systemd-udev package and it has been improved to allow simplifications. For the new installkernel application, as Davide says: <<The %post currently does a shuffling dance before calling installkernel. This isn't actually necessary afaict, and the current implementation ends up triggering downstream issues such as https://github.com/systemd/systemd/issues/29568 This commit simplifies the logic to remove the shuffling. For reference, the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post section to create initramfs and grub hooks").>> But we need to keep the old behavior as well, because the old installkernel application from grubby package, does not allow this simplification and we need to be backward compatible to avoid issues with the different packages. So the easiest solution is to check the package that provides the installkernel application, and simplify (and fix for this application at the same time), only if the package is systemd-udev. cc: stable(a)vger.kernel.org Co-Developed-by: Davide Cavalca <dcavalca(a)meta.com> Signed-off-by: Jose Ignacio Tornos Martinez <jtornosm(a)redhat.com> --- V1 -> V2: - Complete to be backward compatible with the previous installkernel application. scripts/package/kernel.spec | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/scripts/package/kernel.spec b/scripts/package/kernel.spec index 3eee0143e0c5..d4276ddb6645 100644 --- a/scripts/package/kernel.spec +++ b/scripts/package/kernel.spec @@ -77,12 +77,16 @@ rm -rf %{buildroot} %post if [ -x /sbin/installkernel -a -r /boot/vmlinuz-%{KERNELRELEASE} -a -r /boot/System.map-%{KERNELRELEASE} ]; then +if [ $(rpm -qf /sbin/installkernel --queryformat "%{n}") = systemd-udev ];then +/sbin/installkernel %{KERNELRELEASE} /boot/vmlinuz-%{KERNELRELEASE} /boot/System.map-%{KERNELRELEASE} +else cp /boot/vmlinuz-%{KERNELRELEASE} /boot/.vmlinuz-%{KERNELRELEASE}-rpm cp /boot/System.map-%{KERNELRELEASE} /boot/.System.map-%{KERNELRELEASE}-rpm rm -f /boot/vmlinuz-%{KERNELRELEASE} /boot/System.map-%{KERNELRELEASE} /sbin/installkernel %{KERNELRELEASE} /boot/.vmlinuz-%{KERNELRELEASE}-rpm /boot/.System.map-%{KERNELRELEASE}-rpm rm -f /boot/.vmlinuz-%{KERNELRELEASE}-rpm /boot/.System.map-%{KERNELRELEASE}-rpm fi +fi %preun if [ -x /sbin/new-kernel-pkg ]; then -- 2.43.0

[PATCH v2] KVM: arm64: Fix circular locking dependency

by Sebastian Ene

The rule inside kvm enforces that the vcpu->mutex is taken *inside* kvm->lock. The rule is violated by the pkvm_create_hyp_vm() which acquires the kvm->lock while already holding the vcpu->mutex lock from kvm_vcpu_ioctl(). Avoid the circular locking dependency altogether by protecting the hyp vm handle with the config_lock, much like we already do for other forms of VM-scoped data.

[PATCH] PCI: qcom: Fix another deadlock when enabling ASPM

by Johan Hovold

A last minute revert in 6.7-final introduced a potential deadlock when enabling ASPM during probe of Qualcomm PCIe controllers as reported by lockdep: ============================================ WARNING: possible recursive locking detected 6.7.0 #40 Not tainted -------------------------------------------- kworker/u16:5/90 is trying to acquire lock: ffffacfa78ced000 (pci_bus_sem){++++}-{3:3}, at: pcie_aspm_pm_state_change+0x58/0xdc but task is already holding lock: ffffacfa78ced000 (pci_bus_sem){++++}-{3:3}, at: pci_walk_bus+0x34/0xbc other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(pci_bus_sem); lock(pci_bus_sem); *** DEADLOCK *** Call trace: print_deadlock_bug+0x25c/0x348 __lock_acquire+0x10a4/0x2064 lock_acquire+0x1e8/0x318 down_read+0x60/0x184 pcie_aspm_pm_state_change+0x58/0xdc pci_set_full_power_state+0xa8/0x114 pci_set_power_state+0xc4/0x120 qcom_pcie_enable_aspm+0x1c/0x3c [pcie_qcom] pci_walk_bus+0x64/0xbc qcom_pcie_host_post_init_2_7_0+0x28/0x34 [pcie_qcom] The deadlock can easily be reproduced on machines like the Lenovo ThinkPad X13s by adding a delay to increase the race window during asynchronous probe where another thread can take a write lock. Add a new pci_set_power_state_locked() and associated helper functions that can be called with the PCI bus semaphore held to avoid taking the read lock twice.

[PATCH] kbuild: tools: drop overridden CFLAGS from MAKEOVERRIDES

by Max Filippov

Some Makefiles under tools/ use the 'override CFLAGS += ...' construct to add a few required options to CFLAGS passed by the user. Unfortunately that only works when user passes CFLAGS as an environment variable, i.e. CFLAGS=... make ... and not in case when CFLAGS are passed as make command line arguments: make ... CFLAGS=... It happens because in the latter case CFLAGS=... is recorded in the make variable MAKEOVERRIDES and this variable is passed in its original form to all $(MAKE) subcommands, taking precedence over modified CFLAGS value passed in the environment variable. E.g. this causes build failure for gpio and iio tools when the build is run with user CFLAGS because of missing _GNU_SOURCE definition needed for the asprintf(). One way to fix it is by removing overridden variables from the MAKEOVERRIDES. Add macro 'drop-var-from-overrides' that removes a definition of a variable passed to it from the MAKEOVERRIDES and use it to fix CFLAGS passing for tools/gpio and tools/iio.

[PATCH] arm64/signal: Don't assume that TIF_SVE means we saved SVE state

by Mark Brown

When we are in a syscall we will only save the FPSIMD subset even though the task still has access to the full register set, and on context switch we will only remove TIF_SVE when loading the register state. This means that the signal handling code should not assume that TIF_SVE means that the register state is stored in SVE format, it should instead check the format that was recorded during save.

In this case, xrstor tries to restore and accesses the unmapped area which results in a fault. But fault_in_readable succeeds because buf + fx_sw->xstate_size is within the still mapped area, so it goes back and tries xrstor again. It will spin in this loop forever. Instead, fault in the maximum size which can be touched by XRSTOR (taken from fpstate->user_size).

[PATCH] usb: ulpi: Fix debugfs directory leak

by Sean Anderson

The ULPI per-device debugfs root is named after the ulpi device's parent, but ulpi_unregister_interface tries to remove a debugfs directory named after the ulpi device itself. This results in the directory sticking around and preventing subsequent (deferred) probes from succeeding. Change the directory name to match the ulpi device.

[PATCH net v2] net: stmmac: protect updates of 64-bit statistics counters

by Petr Tesarik

As explained by a comment in <linux/u64_stats_sync.h>, write side of struct u64_stats_sync must ensure mutual exclusion, or one seqcount update could be lost on 32-bit platforms, thus blocking readers forever. Such lockups have been observed in real world after stmmac_xmit() on one CPU raced with stmmac_napi_poll_tx() on another CPU. To fix the issue without introducing a new lock, split the statics into three parts: 1. fields updated only under the tx queue lock, 2. fields updated only during NAPI poll, 3. fields updated only from interrupt context, Updates to fields in the first two groups are already serialized through other locks. It is sufficient to split the existing struct u64_stats_sync so that each group has its own. Note that tx_set_ic_bit is updated from both contexts. Split this counter so that each context gets its own, and calculate their sum to get the total value in stmmac_get_ethtool_stats(). For the third group, multiple interrupts may be processed by different CPUs at the same time, but interrupts on the same CPU will not nest. Move fields from this group to a newly created per-cpu struct stmmac_pcpu_stats.

[PATCH v2 RESEND] x86/fpu: call fault_in_readable() for the entire xsave buffer

by Andrei Vagin

Before this change, the expected size of the user space buffer was taken from fx_sw->xstate_size. fx_sw->xstate_size can be changed from user-space, so it is possible construct a sigreturn frame where: * fx_sw->xstate_size is smaller than the size required by valid bits in fx_sw->xfeatures. * user-space unmaps parts of the sigrame fpu buffer so that not all of the buffer required by xrstor is accessible. In this case, xrstor tries to restore and accesses the unmaped area which results in a fault. But fault_in_readable succeeds because buf + fx_sw->xstate_size is within the still mapped area, so it goes back and tries xrstor again. It will spin in this loop forever. Thomas suggested to pass fpstate->user_size into fault_in_readable, because it is the maximum size which can be touched by XRSTOR.

[PATCH 4/4] io_uring/net: limit inline multishot retries

by Jens Axboe

If we have multiple clients and some/all are flooding the receives to such an extent that we can retry a LOT handling multishot receives, then we can be starving some clients and hence serving traffic in an imbalanced fashion. Limit multishot retry attempts to some arbitrary value, whose only purpose serves to ensure that we don't keep serving a single connection for way too long. We default to 32 retries, which should be more than enough to provide fairness, yet not so small that we'll spend too much time requeuing rather than handling traffic.

[PATCH AUTOSEL 5.15 1/3] scsi: target: core: Add TMF to tmr_list handling

by Sasha Levin

[PATCH AUTOSEL 6.1 1/5] dmaengine: apple-admac: Keep upper bits of REG_BUS_WIDTH

by Sasha Levin

From: Hector Martin <marcan(a)marcan.st> [ Upstream commit 306f5df81fcc89b462fbeb9dbe26d9a8ad7c7582 ] For RX channels, REG_BUS_WIDTH seems to default to a value of 0xf00, and macOS preserves the upper bits when setting the configuration in the lower ones. If we reset the upper bits to 0, this causes framing errors on suspend/resume (the data stream "tears" and channels get swapped around). Keeping the upper bits untouched, like the macOS driver does, fixes this issue.

[PATCH v5 RESEND 0/5] Regather scattered PCI-Code

by Philipp Stanner

Second Resend. Would be cool if someone could tell me what I'll have to do so we can get this merged. This is blocking the followup work I've got in the pipe -- @Stable-Kernel: You receive this patch series because its first patch fixes leaks in PCI. Changes in v5: - Add forgotten update to MAINTAINERS file. Changes in v4: - Apply Arnd's Reviewed-by's - Add ifdef CONFIG_HAS_IOPORT_MAP guard in drivers/pci/iomap.c (build error on openrisc) - Fix typo in patch no.5 Changes in v3: - Create a separate patch for the leaks in lib/iomap.c. Make it the series' first patch. (Arnd) - Turns out the aforementioned bug wasn't just accidentally removing iounmap() with the ifdef, it was also missing ioport_unmap() to begin with. Add it. - Move the ARCH_WANTS_GENERIC_IOMEM_IS_IOPORT-mechanism from asm-generic/io.h to asm-generic/ioport.h. (Arnd) - Adjust the implementation of iomem_is_ioport() in asm-generic/io.h so that it matches exactly what pci_iounmap() previously did in lib/pci_iomap.c. (Arnd) - Move the CONFIG_HAS_IOPORT guard in asm-generic/io.h so that iomem_is_ioport() will always be compiled and just returns false if there are no ports. - Add TODOs to several places informing about the generic iomem_is_ioport() in lib/iomap.c not being generic. - Add TODO about the followup work to make drivers/pci/iomap.c's pci_iounmap() actually generic. Changes in v2: - Replace patch 4, previously extending the comment about pci_iounmap() in lib/iomap.c, with a patch that moves pci_iounmap() from that file to drivers/pci/iomap.c, creating a unified version there. (Arnd) - Implement iomem_is_ioport() as a new helper in asm-generic/io.h and lib/iomap.c. (Arnd) - Move the build rule in drivers/pci/Makefile for iomap.o under the guard of #if PCI. This had to be done because when just checking for GENERIC_PCI_IOMAP being defined, the functions don't disappear, which was the case previously in lib/pci_iomap.c, where the entire file was made empty if PCI was not set by the guard #ifdef PCI. (Intel's Bots) - Rephares all patches' commit messages a little bit. Sooooooooo. I reworked v1. Please review this carefully, the IO-Ranges are obviously a bit tricky, as is the build-system / ifdef-ery. Arnd has suggested that architectures defining a custom inb() need their own iomem_is_ioport(), as well. I've grepped for inb() and found the following list of archs that define their own: - alpha - arm - m68k <-- - parisc - powerpc - sh - sparc - x86 <-- All of those have their own definitons of pci_iounmap(). Therefore, they don't need our generic version in the first place and, thus, also need no iomem_is_ioport(). The two exceptions are x86 and m68k. The former uses lib/iomap.c through CONFIG_GENERIC_IOMAP, as Arnd pointed out in the previous discussion (thus, CONFIG_GENERIC_IOMAP is not really generic in this regard). So as I see it, only m68k WOULD need its own custom definition of iomem_is_ioport(). But as I understand it it doesn't because it uses the one from asm-generic/pci_iomap.h ?? I wasn't entirely sure how to deal with the address ranges for the generic implementation in asm-generic/io.h. It's marked with a TODO. Input appreciated. I removed the guard around define pci_iounmap in asm-generic/io.h. An alternative would be to have it be guarded by CONFIG_GENERIC_IOMAP and CONFIG_GENERIC_PCI_IOMAP, both. Without such a guard, there is no collision however, because generic pci_iounmap() from drivers/pci/iomap.c will only get pulled in when CONFIG_GENERIC_PCI_IOMAP is actually set. I cross-built this for a variety of architectures, including the usual suspects (s390, m68k). So far successfully. But let's see what Intel's robots say :O P. Original cover letter: Hi! So it seems that since ca. 2007 the PCI code has been scattered a bit. PCI's devres code, which is only ever used by users of the entire PCI-subsystem anyways, resides in lib/devres.c and is guarded by an ifdef PCI, just as the content of lib/pci_iomap.c is. It, thus, seems reasonable to move all of that. As I were at it, I moved as much of the devres-specific code from pci.c to devres.c, too. The only exceptions are four functions that are currently difficult to move. More information about that can be read here [1]. I noticed these scattered files while working on (new) PCI-specific devres functions. If we can get this here merged, I'll soon send another patch series that addresses some API-inconsistencies and could move the devres-part of the four remaining functions. I don't want to do that in this series as this here is only about moving code, whereas the next series would have to actually change API behavior. I successfully (cross-)built this for x86, x86_64, AARCH64 and ARM (allyesconfig). I booted a kernel with it on x86_64, with a Fedora desktop environment as payload. The OS came up fine I hope this is OK. If we can get it in, we'd soon have a very consistent PCI API again. Regards, P.

Because such machines use tlb-based per-cpu base address rather than dmw-based per-cpu base address, resulting per-cpu variables can only be accessed after tlb_init(). But rcutree_report_cpu_starting() is now called before tlb_init() and accesses per-cpu variables indeed. Since the original patch want to avoid the lockdep warning caused by page allocation in tlb_init(), we can move rcutree_report_cpu_starting() to tlb_init() where after tlb exception configuration but before page allocation.

[PATCH 5.15.x] RDMA/irdma: Ensure iWarp QP queue memory is OS paged aligned

by Shiraz Saleem

From: Mike Marciniszyn <mike.marciniszyn(a)intel.com> [ Upstream commit 0a5ec366de7e94192669ba08de6ed336607fd282 ] The SQ is shared for between kernel and used by storing the kernel page pointer and passing that to a kmap_atomic().

Both the cs_nsec and the wd_nsec value indicate that the readout interval was circa 14.5 seconds. The observed behaviour is that watchdog checks failed for large readout intervals on 8 NUMA node machines. This indicates that the size of the skew was directly proportinal to the length of the readout interval on those machines. The measured clocksource skew, 668 microseconds, was evaluated against a threshold (the md variable) that is suited for readout intervals of roughly WATCHDOG_INTERVAL, i.e. HZ >> 1, which is 0.5 second. The intention of 2e27e793e280 ("clocksource: Reduce clocksource-skew threshold") was to tighten the threshold for evaluating skew and set the lower bound for the uncertainty_margin of clocksources to twice WATCHDOG_MAX_SKEW. Later in c37e85c135ce ("clocksource: Loosen clocksource watchdog constraints"), the WATCHDOG_MAX_SKEW constant was increased to 125 microseconds to fit the limit of NTP, which is able to use a clocksource that suffers from up to 500 microseconds of skew per second. Both the TSC and the HPET use default uncertainty_margin. When the readout interval gets stretched the default uncertainty_margin is no longer a suitable lower bound for evaluating skew - it imposes a limit that is far stricter than the skew with which NTP can deal. The root causes of the skew being directly proportinal to the length of the readout interval are: * the inaccuracy of the shift/mult pairs of clocksources and the watchdog * the conversion to nanoseconds is imprecise for large readout intervals Prevent this by skipping the current watchdog check if the readout interval exceeds 2 * WATCHDOG_INTERVAL. Considering the maximum readout interval of 2 * WATCHDOG_INTERVAL, the current default uncertainty margin (of the TSC and HPET) corresponds to a limit on clocksource skew of 250 ppm (microseconds of skew per second). To keep the limit imposed by NTP (500 microseconds of skew per second) for all possible readout intervals, the margins would have to be scaled so that the threshold value is proportional to the length of the actual readout interval. As for why the readout interval may get stretched: Since the watchdog is executed in softirq context the expiration of the watchdog timer can get severely delayed on account of a ksoftirqd thread not getting to run in a timely manner. Surely, a system with such belated softirq execution is not working well and the scheduling issue should be looked into but the clocksource watchdog should be able to deal with it accordingly.

[PATCH v6 0/6] PCI: qcom: Add support for OPP

by Krishna chaitanya chundru

This patch adds support for OPP to vote for the performance state of RPMH power domain based upon GEN speed it PCIe got enumerated. QCOM Resource Power Manager-hardened (RPMh) is a hardware block which maintains hardware state of a regulator by performing max aggregation of the requests made by all of the processors. PCIe controller can operate on different RPMh performance state of power domain based up on the speed of the link. And this performance state varies from target to target. It is manadate to scale the performance state based up on the PCIe speed link operates so that SoC can run under optimum power conditions. Add Operating Performance Points(OPP) support to vote for RPMh state based upon GEN speed link is operating. Before link up PCIe driver will vote for the maximum performance state. As now we are adding ICC BW vote in OPP, the ICC BW voting depends both GEN speed and link width using opp-level to indicate the opp entry table will be difficult. In PCIe certain gen speeds like GEN1x2 & GEN2X1 or GEN3x2 & GEN4x1 use same icc bw if we use freq in the opp table to represent the PCIe Gen speed number of PCIe entries can reduced. So going back to use freq in the opp table instead of level. Signed-off-by: Krishna chaitanya chundru <quic_krichai(a)quicinc.com> --- Changes frm v5: - Add ICC BW voting as part of OPP, rebase the latest kernel, and only - either OPP or ICC BW voting will supported we removed the patch to - return eror for icc opp update patch. - As we added the icc bw voting in opp table I am not including reviewed - by tags given in previous patch. - Use opp freq to find opp entries as now we need to include pcie link - also in to considerations. - Add CPU-PCIe BW voting which is not present till now. - Drop PCI: qcom: Return error from 'qcom_pcie_icc_update' as either opp or icc bw - only one executes and there is no need to fail if opp or icc update fails. - Link for v5: https://lore.kernel.org/linux-arm-msm/20231101063323.GH2897@thinkpad/T/ Changes from v4: - Added a separate patch for returning error from the qcom_pcie_upadate and moved opp update logic to icc_update and used a bool variable to update the opp. - Addressed comments made by pavan. changes from v3: - Removing the opp vote on suspend when the link is not up and link is not up and add debug prints as suggested by pavan. - Added dev_pm_opp_find_level_floor API to find the highest opp to vote. changes from v2: - Instead of using the freq based opp search use level based as suggested by Dmitry Baryshkov.

[PATCH net] nfc: nci: free rx_data_reassembly skb on NCI device cleanup

by Fedor Pchelkin

rx_data_reassembly skb is stored during NCI data exchange for processing fragmented packets. It is dropped only when the last fragment is processed or when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received. However, the NCI device may be deallocated before that which leads to skb leak. As by design the rx_data_reassembly skb is bound to the NCI device and nothing prevents the device to be freed before the skb is processed in some way and cleaned, free it on the NCI device cleanup.

+ mm-zswap-fix-missing-folio-cleanup-in-writeback-race-path.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm: zswap: fix missing folio cleanup in writeback race path has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-zswap-fix-missing-folio-cleanup-in-writeback-race-path.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Yosry Ahmed <yosryahmed(a)google.com> Subject: mm: zswap: fix missing folio cleanup in writeback race path Date: Thu, 25 Jan 2024 08:51:27 +0000 In zswap_writeback_entry(), after we get a folio from __read_swap_cache_async(), we grab the tree lock again to check that the swap entry was not invalidated and recycled. If it was, we delete the folio we just added to the swap cache and exit. However, __read_swap_cache_async() returns the folio locked when it is newly allocated, which is always true for this path, and the folio is ref'd. Make sure to unlock and put the folio before returning. This was discovered by code inspection, probably because this path handles a race condition that should not happen often, and the bug would not crash the system, it will only strand the folio indefinitely.

[PATCH v2] mips: Call lose_fpu(0) before initializing fcr31 in mips_set_personality_nan

by Xi Ruoyao

If we still own the FPU after initializing fcr31, when we are preempted the dirty value in the FPU will be read out and stored into fcr31, clobbering our setting. This can cause an improper floating-point environment after execve(). For example: zsh% cat measure.c #include <fenv.h> int main() { return fetestexcept(FE_INEXACT); } zsh% cc measure.c -o measure -lm zsh% echo $((1.0/3)) # raising FE_INEXACT 0.33333333333333331 zsh% while ./measure; do ; done (stopped in seconds) Call lose_fpu(0) before setting fcr31 to prevent this.

[PATCH 5.15.y] cifs: fix off-by-one in SMB2_query_info_init()

by Harshit Mogalapalli

Bug: After mounting the cifs fs, it complains with Resource temporarily unavailable messages. [root@vm1 xfstests-dev]# ./check -g quick -s smb3 TEST_DEV=//<SERVER_IP>/TEST is mounted but not a type cifs filesystem [root@vm1 xfstests-dev]# df df: /mnt/test: Resource temporarily unavailable Paul's analysis of the bug: Bug is related to an off-by-one in smb2_set_next_command() when the client attempts to pad SMB2_QUERY_INFO request -- since it isn't 8 byte aligned -- even though smb2_query_info_compound() doesn't provide an extra iov for such padding. v5.15.y doesn't have eb3e28c1e89b ("smb3: Replace smb2pdu 1-element arrays with flex-arrays") and the commit does if (unlikely(check_add_overflow(input_len, sizeof(*req), &len) || len > CIFSMaxBufSize)) return -EINVAL; so sizeof(*req) will wrongly include the extra byte from smb2_query_info_req::Buffer making @len unaligned and therefore causing OOB in smb2_set_next_command().

[PATCH] arm64: dts: qcom: sm8450-hdk: correct AMIC4 and AMIC5 microphones

by Krzysztof Kozlowski

Due to lack of documentation the AMIC4 and AMIC5 analogue microphones were never actually working, so the audio routing for them was added hoping it is correct. It turned out not correct - their routing should point to SWR_INPUT0 (so audio mixer TX SMIC MUX0 = SWR_MIC0) and SWR_INPUT1 (so audio mixer TX SMIC MUX0 = SWR_MIC1), respectively. With proper mixer settings and fixed LPASS TX macr codec TX SMIC MUXn widgets, this makes all microphones working on HDK8450.

For example, if dc pipe 1 and 2 are used, their dml pipe indices would be 0 and 1 respectively. However update_pipe_slice_table_with_split_flags doesn't skip indices for free pipes.
