[PATCH 1/8] drm/probe-helper: warn about negative .get_modes()

by Jani Nikula

The .get_modes() callback is supposed to return the number of modes, never a negative error code. If a negative value is returned, it'll just be interpreted as a negative count, and added to previous calculations. Document the rules, but handle the negative values gracefully with an error message.

[PATCH v3 1/5] efi/libstub: Use correct event size when measuring data into the TPM

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> Our efi_tcg2_tagged_event is not defined in the EFI spec, but it is not a local invention either: it was taken from the TCG PC Client spec, where it is called TCG_PCClientTaggedEvent. This spec also contains some guidance on how to populate it, which is not being followed closely at the moment; the event size should cover the TCG_PCClientTaggedEvent and its payload only, but it currently covers the preceding efi_tcg2_event too, and this may result in trailing garbage being measured into the TPM. So rename the struct and document its provenance, and fix up the use so only the tagged event data is represented in the size field.

[PATCH net v2] net: esp: fix bad handling of pages from page_pool

by Dragos Tatulea

When the skb is reorganized during esp_output (!esp->inline), the pages coming from the original skb fragments are supposed to be released back to the system through put_page. But if the skb fragment pages are originating from a page_pool, calling put_page on them will trigger a page_pool leak which will eventually result in a crash. This leak can be easily observed when using CONFIG_DEBUG_VM and doing ipsec + gre (non offloaded) forwarding: BUG: Bad page state in process ksoftirqd/16 pfn:1451b6 page:00000000de2b8d32 refcount:0 mapcount:0 mapping:0000000000000000 index:0x1451b6000 pfn:0x1451b6 flags: 0x200000000000000(node=0|zone=2) page_type: 0xffffffff() raw: 0200000000000000 dead000000000040 ffff88810d23c000 0000000000000000 raw: 00000001451b6000 0000000000000001 00000000ffffffff 0000000000000000 page dumped because: page_pool leak Modules linked in: ip_gre gre mlx5_ib mlx5_core xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink iptable_nat nf_nat xt_addrtype br_netfilter rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi ib_umad rdma_cm ib_ipoib iw_cm ib_cm ib_uverbs ib_core overlay zram zsmalloc fuse [last unloaded: mlx5_core] CPU: 16 PID: 96 Comm: ksoftirqd/16 Not tainted 6.8.0-rc4+ #22 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x36/0x50 bad_page+0x70/0xf0 free_unref_page_prepare+0x27a/0x460 free_unref_page+0x38/0x120 esp_ssg_unref.isra.0+0x15f/0x200 esp_output_tail+0x66d/0x780 esp_xmit+0x2c5/0x360 validate_xmit_xfrm+0x313/0x370 ? validate_xmit_skb+0x1d/0x330 validate_xmit_skb_list+0x4c/0x70 sch_direct_xmit+0x23e/0x350 __dev_queue_xmit+0x337/0xba0 ? nf_hook_slow+0x3f/0xd0 ip_finish_output2+0x25e/0x580 iptunnel_xmit+0x19b/0x240 ip_tunnel_xmit+0x5fb/0xb60 ipgre_xmit+0x14d/0x280 [ip_gre] dev_hard_start_xmit+0xc3/0x1c0 __dev_queue_xmit+0x208/0xba0 ? nf_hook_slow+0x3f/0xd0 ip_finish_output2+0x1ca/0x580 ip_sublist_rcv_finish+0x32/0x40 ip_sublist_rcv+0x1b2/0x1f0 ? ip_rcv_finish_core.constprop.0+0x460/0x460 ip_list_rcv+0x103/0x130 __netif_receive_skb_list_core+0x181/0x1e0 netif_receive_skb_list_internal+0x1b3/0x2c0 napi_gro_receive+0xc8/0x200 gro_cell_poll+0x52/0x90 __napi_poll+0x25/0x1a0 net_rx_action+0x28e/0x300 __do_softirq+0xc3/0x276 ? sort_range+0x20/0x20 run_ksoftirqd+0x1e/0x30 smpboot_thread_fn+0xa6/0x130 kthread+0xcd/0x100 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x31/0x50 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork_asm+0x11/0x20 </TASK> The suggested fix is to introduce a new wrapper (skb_page_unref) that covers page refcounting for page_pool pages as well.

This can happen if the hardware is still using the data associated with a TRB after the usb_request's ->complete call has been made. Instead of immediately releasing a request when a Missed ISOC interrupt has occurred, this change will add logic to cancel the request instead where it will eventually be released when the END_TRANSFER command has completed. This logic is similar to some of the cleanup done in dwc3_gadget_ep_dequeue.

[PATCH v3 0/3] Support intra-function call validation

by Rui Qi

Since kernel version 5.4.217 LTS, there has been an issue with the kernel live patching feature becoming unavailable. When compiling the sample code for kernel live patching, the following message is displayed when enabled: livepatch: klp_check_stack: kworker/u256:6:23490 has an unreliable stack Reproduction steps: 1.git checkout v5.4.269 -b v5.4.269 2.make defconfig 3. Set CONFIG_LIVEPATCH=y、CONFIG_SAMPLE_LIVEPATCH=m 4. make -j bzImage 5. make samples/livepatch/livepatch-sample.ko 6. qemu-system-x86_64 -kernel arch/x86_64/boot/bzImage -nographic -append "console=ttyS0" -initrd initrd.img -m 1024M 7. insmod livepatch-sample.ko Kernel live patch cannot complete successfully. After some debugging, the immediate cause of the patch failure is an error in stack checking. The logs are as follows: [ 340.974853] livepatch: klp_check_stack: kworker/u256:0:23486 has an unreliable stack [ 340.974858] livepatch: klp_check_stack: kworker/u256:1:23487 has an unreliable stack [ 340.974863] livepatch: klp_check_stack: kworker/u256:2:23488 has an unreliable stack [ 340.974868] livepatch: klp_check_stack: kworker/u256:5:23489 has an unreliable stack [ 340.974872] livepatch: klp_check_stack: kworker/u256:6:23490 has an unreliable stack ...... BTW,if you use the v5.4.217 tag for testing, make sure to set CONFIG_RETPOLINE = y and CONFIG_LIVEPATCH = y, and other steps are consistent with v5.4.269 After investigation, The problem is strongly related to the commit 8afd1c7da2b0 ("x86/speculation: Change FILL_RETURN_BUFFER to work with objtool"), which would cause incorrect ORC entries to be generated, and the v5.4.217 version can undo this commit to make kernel livepatch work normally. It is a back-ported upstream patch with some code adjustments,from the git log, the author also mentioned no intra-function call validation support. Based on commit 6e1f54a4985b63bc1b55a09e5e75a974c5d6719b (Linux 5.4.269), This patchset adds stack validation support for intra-function calls, allowing the kernel live patching feature to work correctly. v3 - v2 - fix the compile error in arch/x86/kvm/svm.c, the error message is../arch/x86/include/asm/nospec-branch.h: 313: Error: no such instruction: 'unwind_hint_empty' v2 - v1 - add the tag "Cc: stable(a)vger.kernel.org" in the sign-off area for patch x86/speculation: Support intra-function call - add my own Signed-off to all patches Alexandre Chartre (2): objtool: is_fentry_call() crashes if call has no destination objtool: Add support for intra-function calls Rui Qi (1): x86/speculation: Support intra-function call validation arch/x86/include/asm/nospec-branch.h | 7 ++ arch/x86/include/asm/unwind_hints.h | 2 +- include/linux/frame.h | 11 ++++ .../Documentation/stack-validation.txt | 8 +++ tools/objtool/arch/x86/decode.c | 6 ++ tools/objtool/check.c | 64 +++++++++++++++++-- 6 files changed, 92 insertions(+), 6 deletions(-) -- 2.20.1

[PATCH v1] mm: swap: Fix race between free_swap_and_cache() and swapoff()

by Ryan Roberts

There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map. This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below). Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was valid. This wasn't present in get_swap_device() so I've added it. I couldn't find any existing get_swap_device() call sites where this extra check would cause any false alarms. Details of how to provoke one possible issue (thanks to David Hilenbrand for deriving this): --8<----- __swap_entry_free() might be the last user and result in "count == SWAP_HAS_CACHE". swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0. So the question is: could someone reclaim the folio and turn si->inuse_pages==0, before we completed swap_page_trans_huge_swapped(). Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are still references by swap entries. Process 1 still references subpage 0 via swap entry. Process 2 still references subpage 1 via swap entry. Process 1 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE [then, preempted in the hypervisor etc.] Process 2 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls __try_to_reclaim_swap(). __try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()-> put_swap_folio()->free_swap_slot()->swapcache_free_entries()-> swap_entry_free()->swap_range_free()-> ... WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries); What stops swapoff to succeed after process 2 reclaimed the swap cache but before process1 finished its call to swap_page_trans_huge_swapped()? --8<----- Fixes: 7c00bafee87c ("mm/swap: free swap slots in batch") Closes: https://lore.kernel.org/linux-mm/65a66eb9-41f8-4790-8db2-0c70ea15979f@redha… Cc: stable(a)vger.kernel.org Signed-off-by: Ryan Roberts <ryan.roberts(a)arm.com> --- Applies on top of v6.8-rc6 and mm-unstable (b38c34939fe4).

[PATCH v4 0/3] Disable automatic load CCS load balancing

by Andi Shyti

Hi, I have to admit that v3 was a lazy attempt. This one should be on the right path. this series does basically two things: 1. Disables automatic load balancing as adviced by the hardware workaround. 2. Assigns all the CCS slices to one single user engine. The user will then be able to query only one CCS engine I'm using here the "Requires: " tag, but I'm not sure the commit id will be valid, on the other hand, I don't know what commit id I should use. Thanks Tvrtko, Matt, John and Joonas for your reviews! Andi Changelog ========= v3 -> v4 - Reword correctly the comment in the workaround - Fix a buffer overflow (Thanks Joonas) - Handle properly the fused engines when setting the CCS mode. v2 -> v3 - Simplified the algorithm for creating the list of the exported uabi engines. (Patch 1) (Thanks, Tvrtko) - Consider the fused engines when creating the uabi engine list (Patch 2) (Thanks, Matt) - Patch 4 now uses a the refactoring from patch 1, in a cleaner outcome. v1 -> v2 - In Patch 1 use the correct workaround number (thanks Matt). - In Patch 2 do not add the extra CCS engines to the exposed UABI engine list and adapt the engine counting accordingly (thanks Tvrtko). - Reword the commit of Patch 2 (thanks John).

[PATCH] can: mcp251xfd: fix infinite loop when xmit fails

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> When the mcp251xfd_start_xmit() function fails, the driver stops processing messages, and the interrupt routine does not return, running indefinitely even after killing the running application. Error messages: [ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16 [ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3). ... and repeat forever. The issue can be triggered when multiple devices share the same SPI interface. And there is concurrent access to the bus. The problem occurs because tx_ring->head increments even if mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX package while still expecting a response in mcp251xfd_handle_tefif_one(). This patch resolves the issue by decreasing tx_ring->head if mcp251xfd_start_xmit() fails. With the fix, if we attempt to trigger the issue again, the driver prints an error and discard the message.

[PATCH net] net: esp: fix bad handling of pages from page_pool

by Dragos Tatulea

When the skb is reorganized during esp_output (!esp->inline), the pages coming from the original skb fragments are supposed to be released back to the system through put_page. But if the skb fragment pages are originating from a page_pool, calling put_page on them will trigger a page_pool leak which will eventually result in a crash. This leak can be easily observed when using CONFIG_DEBUG_VM and doing ipsec + gre (non offloaded) forwarding: BUG: Bad page state in process ksoftirqd/16 pfn:1451b6 page:00000000de2b8d32 refcount:0 mapcount:0 mapping:0000000000000000 index:0x1451b6000 pfn:0x1451b6 flags: 0x200000000000000(node=0|zone=2) page_type: 0xffffffff() raw: 0200000000000000 dead000000000040 ffff88810d23c000 0000000000000000 raw: 00000001451b6000 0000000000000001 00000000ffffffff 0000000000000000 page dumped because: page_pool leak Modules linked in: ip_gre gre mlx5_ib mlx5_core xt_conntrack xt_MASQUERADE nf_conntrack_netlink nfnetlink iptable_nat nf_nat xt_addrtype br_netfilter rpcrdma rdma_ucm ib_iser libiscsi scsi_transport_iscsi ib_umad rdma_cm ib_ipoib iw_cm ib_cm ib_uverbs ib_core overlay zram zsmalloc fuse [last unloaded: mlx5_core] CPU: 16 PID: 96 Comm: ksoftirqd/16 Not tainted 6.8.0-rc4+ #22 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x36/0x50 bad_page+0x70/0xf0 free_unref_page_prepare+0x27a/0x460 free_unref_page+0x38/0x120 esp_ssg_unref.isra.0+0x15f/0x200 esp_output_tail+0x66d/0x780 esp_xmit+0x2c5/0x360 validate_xmit_xfrm+0x313/0x370 ? validate_xmit_skb+0x1d/0x330 validate_xmit_skb_list+0x4c/0x70 sch_direct_xmit+0x23e/0x350 __dev_queue_xmit+0x337/0xba0 ? nf_hook_slow+0x3f/0xd0 ip_finish_output2+0x25e/0x580 iptunnel_xmit+0x19b/0x240 ip_tunnel_xmit+0x5fb/0xb60 ipgre_xmit+0x14d/0x280 [ip_gre] dev_hard_start_xmit+0xc3/0x1c0 __dev_queue_xmit+0x208/0xba0 ? nf_hook_slow+0x3f/0xd0 ip_finish_output2+0x1ca/0x580 ip_sublist_rcv_finish+0x32/0x40 ip_sublist_rcv+0x1b2/0x1f0 ? ip_rcv_finish_core.constprop.0+0x460/0x460 ip_list_rcv+0x103/0x130 __netif_receive_skb_list_core+0x181/0x1e0 netif_receive_skb_list_internal+0x1b3/0x2c0 napi_gro_receive+0xc8/0x200 gro_cell_poll+0x52/0x90 __napi_poll+0x25/0x1a0 net_rx_action+0x28e/0x300 __do_softirq+0xc3/0x276 ? sort_range+0x20/0x20 run_ksoftirqd+0x1e/0x30 smpboot_thread_fn+0xa6/0x130 kthread+0xcd/0x100 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x31/0x50 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork_asm+0x11/0x20 </TASK> The suggested fix is to introduce a new wrapper (skb_page_unref) that covers page refcounting for page_pool pages as well.

[PATCH 1/3] mtd: rawnand: Fix and simplify again the continuous read derivations

We need to avoid the first page if we don't read it entirely. We need to avoid the last page if we don't read it entirely. While rather simple, this logic has been failed in the previous fix.

[PATCH 3/3] mtd: rawnand: Ensure all continuous terms are always in sync

by Miquel Raynal

While crossing a LUN boundary, it is probably safer (and clearer) to keep all members of the continuous read structure aligned, including the pause page (which is the last page of the lun or the last page of the continuous read). Once these members properly in sync, we can use the rawnand_cap_cont_reads() helper everywhere to "prepare" the next continuous read if there is one.

by Josua Mayer

Add of_match table for "ti,amc6821" compatible string. This fixes automatic driver loading by userspace when using device-tree, and if built as a module like major linux distributions do. While devices probe just fine with i2c_device_id table, userspace can't match the "ti,amc6821" compatible string from dt with the plain "amc6821" device id.

Re: [REGRESSION] kexec does firmware reboot in kernel v6.7.6

by Eric Hagberg

To add another datapoint to this - I've seen the same problem on Dell PowerEdge R6615 servers... but no others. The problem also crept into the 6.1.79 kernel with the commit mentioned earlier, and is fixed by reverting that commit. Adding nogbpages to the kernel command line can cause the failure to reproduce on that hardware as well.

[PATCH v2 2/2] usb: gadget: tegra-xudc: Fix USB3 PHY retrieval logic

by Wayne Chang

This commit resolves an issue in the tegra-xudc USB gadget driver that incorrectly fetched USB3 PHY instances. The problem stemmed from the assumption of a one-to-one correspondence between USB2 and USB3 PHY names and their association with physical USB ports in the device tree. Previously, the driver associated USB3 PHY names directly with the USB3 instance number, leading to mismatches when mapping the physical USB ports. For instance, if using USB3-1 PHY, the driver expect the corresponding PHY name as 'usb3-1'. However, the physical USB ports in the device tree were designated as USB2-0 and USB3-0 as we only have one device controller, causing a misalignment. This commit rectifies the issue by adjusting the PHY naming logic. Now, the driver correctly correlates the USB2 and USB3 PHY instances, allowing the USB2-0 and USB3-1 PHYs to form a physical USB port pair while accurately reflecting their configuration in the device tree by naming them USB2-0 and USB3-0, respectively. The change ensures that the PHY and PHY names align appropriately, resolving the mismatch between physical USB ports and their associated names in the device tree.

[PATCH stable 6.6 and 6.7] NFS: Fix data corruption caused by congestion.

by NeilBrown

when AOP_WRITEPAGE_ACTIVATE is returned (as NFS does when it detects congestion) it is important that the folio is redirtied. nfs_writepage_locked() doesn't do this, so files can become corrupted as writes can be lost. Note that this is not needed in v6.8 as AOP_WRITEPAGE_ACTIVATE cannot be returned. It is needed for kernels v5.18..v6.7. Prior to 6.3 the patch is different as it needs to mention "page", not "folio".

[PATCH v5 1/2] driver core: Introduce device_link_wait_removal()

by Herve Codina

The commit 80dd33cf72d1 ("drivers: base: Fix device link removal") introduces a workqueue to release the consumer and supplier devices used in the devlink. In the job queued, devices are release and in turn, when all the references to these devices are dropped, the release function of the device itself is called. Nothing is present to provide some synchronisation with this workqueue in order to ensure that all ongoing releasing operations are done and so, some other operations can be started safely. For instance, in the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are released and related devlinks are removed (jobs pushed in the workqueue). During the step 2, OF nodes are destroyed but, without any synchronisation with devlink removal jobs, of_overlay_remove() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 Indeed, the missing of_node_put() call is going to be done, too late, from the workqueue job execution. Introduce device_link_wait_removal() to offer a way to synchronize operations waiting for the end of devlink removals (i.e. end of workqueue jobs). Also, as a flushing operation is done on the workqueue, the workqueue used is moved from a system-wide workqueue to a local one.

[PATCH v5 2/2] of: dynamic: Synchronize of_changeset_destroy() with the devlink removals

by Herve Codina

In the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are destroyed and devlinks are removed. During the step 2, OF nodes are destroyed but __of_changeset_entry_destroy() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 ... Indeed, during the devlink removals performed at step 1, the removal itself releasing the device (and the attached of_node) is done by a job queued in a workqueue and so, it is done asynchronously with respect to function calls. When the warning is present, of_node_put() will be called but wrongly too late from the workqueue job. In order to be sure that any ongoing devlink removals are done before the of_node destruction, synchronize the of_changeset_destroy() with the devlink removals.

[REGRESSION] NULL pointer dereference drm_dp_add_payload_part2

by Leon Weiß

Hello, 54d217406afe250d7a768783baaa79a035f21d38 fixed an issue in drm_dp_add_payload_part2 that lead to a NULL pointer dereference in case state is NULL. The change was (accidentally?) reverted in 5aa1dfcdf0a429e4941e2eef75b006a8c7a8ac49 and the problem reappeared. The issue is rather spurious, but I've had it appear when unplugging a thunderbolt dock. #regzbot introduced 5aa1dfcdf0a429e4941e2eef75b006a8c7a8ac49

[PATCH linux-5.4.y 0/8] Fix the UAF issue caused by the loop driver

by Genjian

From: Genjian Zhang <zhanggenjian(a)kylinos.cn> Hello! We found that 13b2856037a6 ("loop: Check for overflow while configuring loop") lost a unlock loop_ctl_mutex in loop_get_status(...). which caused syzbot to report a UAF issue. However, the upstream patch does not have this issue. So, we revert this patch and directly apply the unmodified upstream patch.

[PATCH v2] btrfs: do not skip re-registration for the mounted device

by Anand Jain

There are reports that since version 6.7 update-grub fails to find the device of the root on systems without initrd and on a single device. This looks like the device name changed in the output of /proc/self/mountinfo: 6.5-rc5 working 18 1 0:16 / / rw,noatime - btrfs /dev/sda8 ... 6.7 not working: 17 1 0:15 / / rw,noatime - btrfs /dev/root ... and "update-grub" shows this error: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?) This looks like it's related to the device name, but grub-probe recognizes the "/dev/root" path and tries to find the underlying device. However there's a special case for some filesystems, for btrfs in particular. The generic root device detection heuristic is not done and it all relies on reading the device infos by a btrfs specific ioctl. This ioctl returns the device name as it was saved at the time of device scan (in this case it's /dev/root). The change in 6.7 for temp_fsid to allow several single device filesystem to exist with the same fsid (and transparently generate a new UUID at mount time) was to skip caching/registering such devices. This also skipped mounted device. One step of scanning is to check if the device name hasn't changed, and if yes then update the cached value. This broke the grub-probe as it always read the device /dev/root and couldn't find it in the system. A temporary workaround is to create a symlink but this does not survive reboot. The right fix is to allow updating the device path of a mounted filesystem even if this is a single device one. In the fix, check if the device's major:minor number matches with the cached device. If they do, then we can allow the scan to happen so that device_list_add() can take care of updating the device path. The file descriptor remains unchanged. This does not affect the temp_fsid feature, the UUID of the mounted filesystem remains the same and the matching is based on device major:minor which is unique per mounted filesystem. This covers the path when the device (that exists for all mounted devices) name changes, updating /dev/root to /dev/sdx. Any other single device with filesystem and is not mounted is still skipped. Note that if a system is booted and initial mount is done on the /dev/root device, this will be the cached name of the device. Only after the command "btrfs device scan" it will change as it triggers the rename. The fix was verified by users whose systems were affected.

[PATCH 2/2] usb: gadget: tegra-xudc: Fix USB3 PHY retrieval logic

by Wayne Chang

This commit resolves an issue in the tegra-xudc USB gadget driver that incorrectly fetched USB3 PHY instances. The problem stemmed from the assumption of a one-to-one correspondence between USB2 and USB3 PHY names and their association with physical USB ports in the device tree. Previously, the driver associated USB3 PHY names directly with the USB3 instance number, leading to mismatches when mapping the physical USB ports. For instance, if using USB3-1 PHY, the driver expect the corresponding PHY name as 'usb3-1'. However, the physical USB ports in the device tree were designated as USB2-0 and USB3-0 as we only have one device controller, causing a misalignment. This commit rectifies the issue by adjusting the PHY naming logic. Now, the driver correctly correlates the USB2 and USB3 PHY instances, allowing the USB2-0 and USB3-1 PHYs to form a physical USB port pair while accurately reflecting their configuration in the device tree by naming them USB2-0 and USB3-0, respectively. The change ensures that the PHY and PHY names align appropriately, resolving the mismatch between physical USB ports and their associated names in the device tree.

[PATCH v4 2/2] of: dynamic: Synchronize of_changeset_destroy() with the devlink removals

by Herve Codina

In the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are destroyed and devlinks are removed. During the step 2, OF nodes are destroyed but __of_changeset_entry_destroy() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 ... Indeed, during the devlink removals performed at step 1, the removal itself releasing the device (and the attached of_node) is done by a job queued in a workqueue and so, it is done asynchronously with respect to function calls. When the warning is present, of_node_put() will be called but wrongly too late from the workqueue job. In order to be sure that any ongoing devlink removals are done before the of_node destruction, synchronize the of_changeset_destroy() with the devlink removals.

[PATCH v4 1/2] driver core: Introduce device_link_wait_removal()

by Herve Codina

The commit 80dd33cf72d1 ("drivers: base: Fix device link removal") introduces a workqueue to release the consumer and supplier devices used in the devlink. In the job queued, devices are release and in turn, when all the references to these devices are dropped, the release function of the device itself is called. Nothing is present to provide some synchronisation with this workqueue in order to ensure that all ongoing releasing operations are done and so, some other operations can be started safely. For instance, in the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are released and related devlinks are removed (jobs pushed in the workqueue). During the step 2, OF nodes are destroyed but, without any synchronisation with devlink removal jobs, of_overlay_remove() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 Indeed, the missing of_node_put() call is going to be done, too late, from the workqueue job execution. Introduce device_link_wait_removal() to offer a way to synchronize operations waiting for the end of devlink removals (i.e. end of workqueue jobs). Also, as a flushing operation is done on the workqueue, the workqueue used is moved from a system-wide workqueue to a local one.

[PATCH wpan] mac802154: fix llsec key resources release in mac802154_llsec_key_del

by Fedor Pchelkin

mac802154_llsec_key_del() can free resources of a key directly without following the RCU rules for waiting before the end of a grace period. This may lead to use-after-free in case llsec_lookup_key() is traversing the list of keys in parallel with a key deletion: refcount_t: addition on 0; use-after-free.

[PATCH v4] USB:UAS:return ENODEV when submit urbs fail with device not attached

by Weitao Wang

In the scenario of entering hibernation with udisk in the system, if the udisk was gone or resume fail in the thaw phase of hibernation. Its state will be set to NOTATTACHED. At this point, usb_hub_wq was already freezed and can't not handle disconnect event. Next, in the poweroff phase of hibernation, SYNCHRONIZE_CACHE SCSI command will be sent to this udisk when poweroff this scsi device, which will cause uas_submit_urbs to be called to submit URB for sense/data/cmd pipe. However, these URBs will submit fail as device was set to NOTATTACHED state. Then, uas_submit_urbs will return a value SCSI_MLQUEUE_DEVICE_BUSY to the caller. That will lead the SCSI layer go into an ugly loop and system fail to go into hibernation. On the other hand, when we specially check for -ENODEV in function uas_queuecommand_lck, returning DID_ERROR to SCSI layer will cause device poweroff fail and system shutdown instead of entering hibernation. To fix this issue, let uas_submit_urbs to return original generic error when submitting URB failed. At the same time, we need to translate -ENODEV to DID_NOT_CONNECT for the SCSI layer.

[PATCH STABLE v5.15.y] mm/migrate: set swap entry values of THP tail pages properly.

by Zi Yan

From: Zi Yan <ziy(a)nvidia.com> The tail pages in a THP can have swap entry information stored in their private field. When migrating to a new page, all tail pages of the new page need to update ->private to avoid future data corruption. This fix is stable-only, since after commit 07e09c483cbe ("mm/huge_memory: work on folio->swap instead of page->private when splitting folio"), subpages of a swapcached THP no longer requires the maintenance. Adding THPs to the swapcache was introduced in commit 38d8b4e6bdc87 ("mm, THP, swap: delay splitting THP during swap out"), where each subpage of a THP added to the swapcache had its own swapcache entry and required the ->private field to point to the correct swapcache entry.

[PATCH STABLE v5.10.y] mm/migrate: set swap entry values of THP tail pages properly.

by Zi Yan

From: Zi Yan <ziy(a)nvidia.com> The tail pages in a THP can have swap entry information stored in their private field. When migrating to a new page, all tail pages of the new page need to update ->private to avoid future data corruption. This fix is stable-only, since after commit 07e09c483cbe ("mm/huge_memory: work on folio->swap instead of page->private when splitting folio"), subpages of a swapcached THP no longer requires the maintenance. Adding THPs to the swapcache was introduced in commit 38d8b4e6bdc87 ("mm, THP, swap: delay splitting THP during swap out"), where each subpage of a THP added to the swapcache had its own swapcache entry and required the ->private field to point to the correct swapcache entry. Later, when THP migration functionality was implemented in commit 616b8371539a6 ("mm: thp: enable thp migration in generic path"), it initially did not handle the subpages of swapcached THPs, failing to update their ->private fields or replace the subpage pointers in the swapcache.

[REGRESSION] kexec does firmware reboot in kernel v6.7.6

by Pavin Joseph

Hello everyone, #regzbot introduced v6.7.5..v6.7.6 I'm experiencing an issue where kexec does a full firmware reboot instead of kexec reboot. Issue first submitted at OpenSuse bugzilla [0]. OS details as follows: Distributor ID: openSUSE Description: openSUSE Tumbleweed-Slowroll Release: 20240213 Issue has been reproduced by building kernel from source. kexec works as expected in kernel v6.7.5. kexec does full firmware reboot in kernel v6.7.6. I followed the docs here [1] to perform git bisect and find the culprit, hope it's alright as I'm quite out of my depth here. Git bisect logs: git bisect start # status: waiting for both good and bad commits # bad: [b631f5b445dc3379f67ff63a2e4c58f22d4975dc] Linux 6.7.6 git bisect bad b631f5b445dc3379f67ff63a2e4c58f22d4975dc # status: waiting for good commit(s), bad commit known # good: [004dcea13dc10acaf1486d9939be4c793834c13c] Linux 6.7.5 git bisect good 004dcea13dc10acaf1486d9939be4c793834c13c Let me know if there's anything else I can do to help troubleshoot the issue. [0]: https://bugzilla.suse.com/show_bug.cgi?id=1220541 [1]: https://docs.kernel.org/admin-guide/bug-bisect.html Kind regards, Pavin Joseph.

[PATCH v2] mm: swap: Fix race between free_swap_and_cache() and swapoff()

by Ryan Roberts

There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map. This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below). Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was not free. This isn't present in get_swap_device() because it doesn't make sense in general due to the race between getting the reference and swapoff. So I've added an equivalent check directly in free_swap_and_cache(). Details of how to provoke one possible issue (thanks to David Hildenbrand for deriving this): --8<----- __swap_entry_free() might be the last user and result in "count == SWAP_HAS_CACHE". swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0. So the question is: could someone reclaim the folio and turn si->inuse_pages==0, before we completed swap_page_trans_huge_swapped(). Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are still references by swap entries. Process 1 still references subpage 0 via swap entry. Process 2 still references subpage 1 via swap entry. Process 1 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE [then, preempted in the hypervisor etc.] Process 2 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls __try_to_reclaim_swap(). __try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()-> put_swap_folio()->free_swap_slot()->swapcache_free_entries()-> swap_entry_free()->swap_range_free()-> ... WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries); What stops swapoff to succeed after process 2 reclaimed the swap cache but before process1 finished its call to swap_page_trans_huge_swapped()? --8<----- Fixes: 7c00bafee87c ("mm/swap: free swap slots in batch") Closes: https://lore.kernel.org/linux-mm/65a66eb9-41f8-4790-8db2-0c70ea15979f@redha… Cc: stable(a)vger.kernel.org Signed-off-by: Ryan Roberts <ryan.roberts(a)arm.com> --- Hi Andrew, Please replace v1 of this patch in mm-unstable with this version. Changes since v1: - Added comments for get_swap_device() as suggested by David - Moved check that swap entry is not free from get_swap_device() to free_swap_and_cache() since there are some paths that legitimately call with a free offset.

[PATCH 5.10/5.15] scsi: add a length check for VARIABLE_LENGTH_CMD commands

by Mikhail Ukhin

Fuzzing of 5.10 stable branch reports a slab-out-of-bounds error in ata_scsi_pass_thru. The error is fixed in 5.18 by commit ce70fd9a551af7424a7dace2a1ba05a7de8eae27. Backporting this commit would require significant changes to the code so it is bettter to use a simple fix for that particular error. The problem is that the length of the received SCSI command is not validated if scsi_op == VARIABLE_LENGTH_CMD. It can lead to out-of-bounds reading if the user sends a request with SCSI command of length less than 32. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH 2/3] drm/i915/dsb: Fix DSB vblank waits when using VRR

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Looks like the undelayed vblank gets signalled exactly when the active period ends. That is a problem for DSB+VRR when we are already in vblank and expect DSB to start executing as soon as we send the push. Instead of starting the DSB just keeps on waiting for the undelayed vblank which won't signal until the end of the next frame's active period, which is far too late. The end result is that DSB won't have even started executing by the time the flips/etc. have completed. We then wait for an extra 1ms, after which we terminate the DSB and report a timeout: [drm] *ERROR* [CRTC:80:pipe A] DSB 0 timed out waiting for idle (current head=0xfedf4000, head=0x0, tail=0x1080) To fix this let's configure DSB to use the so called VRR "safe window" instead of the undelayed vblank to trigger the DSB vblank logic, when VRR is enabled.

[PATCH 1/3] drm/i915/vrr: Generate VRR "safe window" for DSB

[PATCH net v3] 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 2/3] KVM: arm64: Fix host-programmed guest events in nVHE

by Oliver Upton

Programming PMU events in the host that count during guest execution is a feature supported by perf, e.g. perf stat -e cpu_cycles:G ./lkvm run While this works for VHE, the guest/host event bitmaps are not carried through to the hypervisor in the nVHE configuration. Make kvm_pmu_update_vcpu_events() conditional on whether or not _hardware_ supports PMUv3 rather than if the vCPU as vPMU enabled.

[PATCH v3 2/2] of: overlay: Synchronize of_overlay_remove() with the devlink removals

by Herve Codina

In the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are destroyed and devlinks are removed. During the step 2, OF nodes are destroyed but __of_changeset_entry_destroy() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 ... Indeed, during the devlink removals performed at step 1, the removal itself releasing the device (and the attached of_node) is done by a job queued in a workqueue and so, it is done asynchronously with respect to function calls. When the warning is present, of_node_put() will be called but wrongly too late from the workqueue job. In order to be sure that any ongoing devlink removals are done before the of_node destruction, synchronize the of_overlay_remove() with the devlink removals.

by Shengyu Qu

Since commit b2cb2ae22278f1918f7526b89760ee00b4a81393 ("mfd: axp20x: Generalise handling without interrupt"), interrupt info part for the AXP15060 PMIC is not needed anymore for Statfive Visionfive 2 board. And this would cause kernel to try to enable interrupt line 0, which is not expected. So delete this part from device tree.

[PATCH v2] media: mxl5xx: Move xpt structures off stack

by Nathan Chancellor

When building for LoongArch with clang 18.0.0, the stack usage of probe() is larger than the allowed 2048 bytes: drivers/media/dvb-frontends/mxl5xx.c:1698:12: warning: stack frame size (2368) exceeds limit (2048) in 'probe' [-Wframe-larger-than] 1698 | static int probe(struct mxl *state, struct mxl5xx_cfg *cfg) | ^ 1 warning generated. This is the result of the linked LLVM commit, which changes how the arrays of structures in config_ts() get handled with CONFIG_INIT_STACK_ZERO and CONFIG_INIT_STACK_PATTERN, which causes the above warning in combination with inlining, as config_ts() gets inlined into probe(). This warning can be easily fixed by moving the array of structures off of the stack via 'static const', which is a better location for these variables anyways because they are static data that is only ever read from, never modified, so allocating the stack space is wasteful. This drops the stack usage from 2368 bytes to 256 bytes with the same compiler and configuration.

[PATCH] kbuild: Disable two Clang specific enumeration warnings

by Nathan Chancellor

Clang enables -Wenum-enum-conversion and -Wenum-compare-conditional under -Wenum-conversion. A recent change in Clang strengthened these warnings and they appear frequently in common builds, primarily due to several instances in common headers but there are quite a few drivers that have individual instances as well. include/linux/vmstat.h:508:43: warning: arithmetic between different enumeration types ('enum zone_stat_item' and 'enum numa_stat_item') [-Wenum-enum-conversion] 508 | return vmstat_text[NR_VM_ZONE_STAT_ITEMS + | ~~~~~~~~~~~~~~~~~~~~~ ^ 509 | item]; | ~~~~ drivers/net/wireless/intel/iwlwifi/mvm/mac-ctxt.c:955:24: warning: conditional expression between different enumeration types ('enum iwl_mac_beacon_flags' and 'enum iwl_mac_beacon_flags_v1') [-Wenum-compare-conditional] 955 | flags |= is_new_rate ? IWL_MAC_BEACON_CCK | ^ ~~~~~~~~~~~~~~~~~~ 956 | : IWL_MAC_BEACON_CCK_V1; | ~~~~~~~~~~~~~~~~~~~~~ drivers/net/wireless/intel/iwlwifi/mvm/mac-ctxt.c:1120:21: warning: conditional expression between different enumeration types ('enum iwl_mac_beacon_flags' and 'enum iwl_mac_beacon_flags_v1') [-Wenum-compare-conditional] 1120 | 0) > 10 ? | ^ 1121 | IWL_MAC_BEACON_FILS : | ~~~~~~~~~~~~~~~~~~~ 1122 | IWL_MAC_BEACON_FILS_V1; | ~~~~~~~~~~~~~~~~~~~~~~ While doing arithmetic with different types of enums may be potentially problematic, inspecting several instances of the warning does not reveal any obvious problems. To silence the warnings at the source level, an integral cast must be added to each mismatched enum (which is incredibly ugly when done frequently) or the value must moved out of the enum to a macro, which can remove the type safety offered by enums in other places, such as assignments that would trigger -Wenum-conversion. As the warnings do not appear to have a high signal to noise ratio and the source level silencing options are not sustainable, disable the warnings unconditionally, as they will be enabled with -Wenum-conversion and are supported in all versions of clang that can build the kernel.

[PATCH 5.10.y 0/7] Delay VERW 5.10.y backport

by Pawan Gupta

This is the backport of recently upstreamed series that moves VERW execution to a later point in exit-to-user path. This is needed because in some cases it may be possible for data accessed after VERW executions may end into MDS affected CPU buffers.

[PATCH v3 0/4] Disable automatic load CCS load balancing

by Andi Shyti

Hi, this series does basically two things: 1. Disables automatic load balancing as adviced by the hardware workaround. 2. Assigns all the CCS slices to one single user engine. The user will then be able to query only one CCS engine I'm using here the "Requires: " tag, but I'm not sure the commit id will be valid, on the other hand, I don't know what commit id I should use. Thanks Tvrtko, Matt and John for your reviews! Andi Changelog ========= v2 -> v3 - Simplified the algorithm for creating the list of the exported uabi engines. (Patch 1) (Thanks, Tvrtko) - Consider the fused engines when creating the uabi engine list (Patch 2) (Thanks, Matt) - Patch 4 now uses a the refactoring from patch 1, in a cleaner outcome. v1 -> v2 - In Patch 1 use the correct workaround number (thanks Matt). - In Patch 2 do not add the extra CCS engines to the exposed UABI engine list and adapt the engine counting accordingly (thanks Tvrtko). - Reword the commit of Patch 2 (thanks John).

[PATCH] fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion

by Bart Van Assche

The first kiocb_set_cancel_fn() argument may point at a struct kiocb that is not embedded inside struct aio_kiocb. With the current code, depending on the compiler, the req->ki_ctx read happens either before the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such that it is guaranteed that the IOCB_AIO_RW test happens first.

[PATCH] arm64/mm: Add memory barrier for mm_cid

Currently arm64's switch_mm() doesn't always have an smp_mb() which the core scheduler code has depended upon since commit: commit 223baf9d17f25 ("sched: Fix performance regression introduced by mm_cid") If switch_mm() doesn't call smp_mb(), sched_mm_cid_remote_clear() can unset the activly used cid when it fails to observe active task after it sets lazy_put.

[PATCH] Revert "fs/aio: Make io_cancel() generate completions again"

by Bart Van Assche

Patch "fs/aio: Make io_cancel() generate completions again" is based on the assumption that calling kiocb->ki_cancel() does not complete R/W requests. This is incorrect: the two drivers that call kiocb_set_cancel_fn() callers set a cancellation function that calls usb_ep_dequeue(). According to its documentation, usb_ep_dequeue() calls the completion routine with status -ECONNRESET. Hence this revert.

Its filename is mm-swap-fix-race-between-free_swap_and_cache-and-swapoff.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-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: Ryan Roberts <ryan.roberts(a)arm.com> Subject: mm: swap: fix race between free_swap_and_cache() and swapoff() Date: Tue, 5 Mar 2024 15:13:49 +0000 There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map. This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below). Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was valid. This wasn't present in get_swap_device() so I've added it. I couldn't find any existing get_swap_device() call sites where this extra check would cause any false alarms. Details of how to provoke one possible issue (thanks to David Hildenbrand for deriving this): --8<----- __swap_entry_free() might be the last user and result in "count == SWAP_HAS_CACHE". swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0. So the question is: could someone reclaim the folio and turn si->inuse_pages==0, before we completed swap_page_trans_huge_swapped(). Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are still references by swap entries. Process 1 still references subpage 0 via swap entry. Process 2 still references subpage 1 via swap entry. Process 1 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE [then, preempted in the hypervisor etc.] Process 2 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls __try_to_reclaim_swap(). __try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()-> put_swap_folio()->free_swap_slot()->swapcache_free_entries()-> swap_entry_free()->swap_range_free()-> ... WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries); What stops swapoff to succeed after process 2 reclaimed the swap cache but before process1 finished its call to swap_page_trans_huge_swapped()? --8<----- Link: https://lkml.kernel.org/r/20240305151349.3781428-1-ryan.roberts@arm.com Fixes: 7c00bafee87c ("mm/swap: free swap slots in batch") Closes: https://lore.kernel.org/linux-mm/65a66eb9-41f8-4790-8db2-0c70ea15979f@redha… Signed-off-by: Ryan Roberts <ryan.roberts(a)arm.com> Cc: David Hildenbrand <david(a)redhat.com> Cc: "Huang, Ying" <ying.huang(a)intel.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/swapfile.c | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) --- a/mm/swapfile.c~mm-swap-fix-race-between-free_swap_and_cache-and-swapoff +++ a/mm/swapfile.c @@ -1281,7 +1281,9 @@ struct swap_info_struct *get_swap_device smp_rmb(); offset = swp_offset(entry); if (offset >= si->max) - goto put_out; + goto bad_offset; + if (data_race(!si->swap_map[swp_offset(entry)])) + goto bad_free; return si; bad_nofile: @@ -1289,9 +1291,14 @@ bad_nofile: out: return NULL; put_out: - pr_err("%s: %s%08lx\n", __func__, Bad_offset, entry.val); percpu_ref_put(&si->users); return NULL; +bad_offset: + pr_err("%s: %s%08lx\n", __func__, Bad_offset, entry.val); + goto put_out; +bad_free: + pr_err("%s: %s%08lx\n", __func__, Unused_offset, entry.val); + goto put_out; } static unsigned char __swap_entry_free(struct swap_info_struct *p, @@ -1609,13 +1616,14 @@ int free_swap_and_cache(swp_entry_t entr if (non_swap_entry(entry)) return 1; - p = _swap_info_get(entry); + p = get_swap_device(entry); if (p) { count = __swap_entry_free(p, entry); if (count == SWAP_HAS_CACHE && !swap_page_trans_huge_swapped(p, entry)) __try_to_reclaim_swap(p, swp_offset(entry), TTRS_UNMAPPED | TTRS_FULL); + put_swap_device(p); } return p != NULL; } _ Patches currently in -mm which might be from ryan.roberts(a)arm.com are mm-swap-fix-race-between-free_swap_and_cache-and-swapoff.patch

[PATCH STABLE v5.15.y] mm/migrate: set swap entry values of THP tail pages properly.

by Zi Yan

From: Zi Yan <ziy(a)nvidia.com> The tail pages in a THP can have swap entry information stored in their private field. When migrating to a new page, all tail pages of the new page need to update ->private to avoid future data corruption. Corresponding swapcache entries need to be updated as well. e71769ae5260 ("mm: enable thp migration for shmem thp") fixed it already.

[PATCH] LoongArch: Define the __io_aw() hook as mmiowb()

by Huacai Chen

Commit fb24ea52f78e0d595852e ("drivers: Remove explicit invocations of mmiowb()") remove all mmiowb() in drivers, but it says: "NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation." The mmio in radeon_ring_commit() is protected by a mutex rather than a spinlock, but in the mutex fastpath it behaves similar to spinlock. We can add mmiowb() calls in the radeon driver but the maintainer says he doesn't like such a workaround, and radeon is not the only example of mutex protected mmio. So we should extend the mmiowb tracking system from spinlock to mutex, and maybe other locking primitives. This is not easy and error prone, so we solve it in the architectural code, by simply defining the __io_aw() hook as mmiowb(). And we no longer need to override queued_spin_unlock() so use the generic definition. Without this, we get such an error when run 'glxgears' on weak ordering architectures such as LoongArch: radeon 0000:04:00.0: ring 0 stalled for more than 10324msec radeon 0000:04:00.0: ring 3 stalled for more than 10240msec radeon 0000:04:00.0: GPU lockup (current fence id 0x000000000001f412 last fence id 0x000000000001f414 on ring 3) radeon 0000:04:00.0: GPU lockup (current fence id 0x000000000000f940 last fence id 0x000000000000f941 on ring 0) radeon 0000:04:00.0: scheduling IB failed (-35).

[PATCH] drm/i915/dsi: Go back to the previous INIT_OTP/DISPLAY_ON order, mostly

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Reinstate commit 88b065943cb5 ("drm/i915/dsi: Do display on sequence later on icl+"), for the most part. Turns out some machines (eg. Chuwi Minibook X) really do need that updated order. It is also the order the Windows driver uses. However we can't just undo the revert since that would again break Lenovo 82TQ. After staring at the VBT sequences for both machines I've concluded that the Lenovo 82TQ sequences look somewhat broken: - INIT_OTP is not present at all - what should be in INIT_OTP is found in DISPLAY_ON - what should be in DISPLAY_ON is found in BACKLIGHT_ON (along with the actual backlight stuff) The Chuwi Minibook X on the other hand has a full complement of sequences in its VBT. So let's try to deal with the broken sequences in the Lenovo 82TQ VBT by simply swapping the (non-existent) INIT_OTP sequence with the DISPLAY_ON sequence. Thus we execute DISPLAY_ON when intending to execute INIT_OTP, and execute nothing at all when intending to execute DISPLAY_ON. That should be 100% equivalent to the revert, for such broken VBTs.

[PATCH v2] mmc: tmio: avoid concurrent runs of mmc_request_done()

by Wolfram Sang

With the to-be-fixed commit, the reset_work handler cleared 'host->mrq' outside of the spinlock protected critical section. That leaves a small race window during execution of 'tmio_mmc_reset()' where the done_work handler could grab a pointer to the now invalid 'host->mrq'. Both would use it to call mmc_request_done() causing problems (see link below). However, 'host->mrq' cannot simply be cleared earlier inside the critical section. That would allow new mrqs to come in asynchronously while the actual reset of the controller still needs to be done. So, like 'tmio_mmc_set_ios()', an ERR_PTR is used to prevent new mrqs from coming in but still avoiding concurrency between work handlers.

[PATCH 1/1] xhci: Fix failure to detect ring expansion need.

by Mathias Nyman

Ring expansion checker may incorrectly assume a completely full ring is empty, missing the need for expansion. This is due to a special empty ring case where the dequeue ends up ahead of the enqueue pointer. This is seen when enqueued TRBs fill up exactly a segment, with enqueue then pointing to the end link TRB. Once those TRBs are handled the dequeue pointer will follow the link TRB and end up pointing to the first entry on the next segment, past the enqueue. This same enqueue - dequeue condition can be true if a ring is full, with enqueue ending on that last link TRB before the dequeue pointer on the next segment. This can be seen when queuing several ~510 small URBs via usbfs in one go before a single one is handled (i.e. dequeue not moved from first entry in segment). Expand the ring already when enqueue reaches the link TRB before the dequeue segment, instead of expanding it when enqueue moves into the dequeue segment.

[PATCH v2] btrfs: scrub: fix false alerts on zoned device scrubing

by Qu Wenruo

[BUG] When using zoned devices (zbc), scrub would always report super block errors like the following: # btrfs scrub start -fB /mnt/btrfs/ Starting scrub on devid 1 scrub done for b7b5c759-1baa-4561-a0ca-b8d0babcde56 Scrub started: Tue Mar 5 12:49:14 2024 Status: finished Duration: 0:00:00 Total to scrub: 288.00KiB Rate: 288.00KiB/s Error summary: super=2 Corrected: 0 Uncorrectable: 0 Unverified: 0 [CAUSE] Since the very beginning of scrub, we always go with btrfs_sb_offset() to grab the super blocks. This is fine for regular btrfs filesystems, but for zoned btrfs, super blocks are stored in dedicated zones with a ring buffer like structure. This means the old btrfs_sb_offset() is not able to give the correct bytenr for us to grabbing the super blocks, thus except the primary super block, the rest would be garbage and cause the above false alerts. [FIX] Instead of btrfs_sb_offset(), go with btrfs_sb_log_location() which is zoned friendly, to grab the correct super block location. This would introduce new error patterns, as btrfs_sb_log_location() can fail with extra errors. Here for -ENOENT we just end the scrub as there are no more super blocks. For other errors, we record it as a super block error and exit.

[PATCH v3 09/10] arm64: dts: qcom: sc8280xp-x13s: disable ASPM L0s for NVMe and modem

There are indications that ASPM L0s is not working very well on this machine so disable it also for the NVMe and modem controllers for now. Note that this is done as a precaution based on problems with the Wi-Fi on the X13s as well as the NVMe, modem and Wi-Fi on the sc8280xp-crd reference design (the NVMe controller on my X13s does not support L0s and the machine lacks a modem).

[PATCH v3 04/10] PCI: qcom: Add support for disabling ASPM L0s in devicetree

by Johan Hovold

Commit 9f4f3dfad8cf ("PCI: qcom: Enable ASPM for platforms supporting 1.9.0 ops") started enabling ASPM unconditionally when the hardware claims to support it. This triggers Correctable Errors for some PCIe devices on machines like the Lenovo ThinkPad X13s, which could indicate an incomplete driver ASPM implementation or that the hardware does in fact not support L0s. Add support for disabling ASPM L0s in the devicetree when it is not supported on a particular machine and controller. Note that only the 1.9.0 ops enable ASPM currently.

[PATCH v2 0/3] Support intra-function call validation

by Rui Qi

Since kernel version 5.4.217 LTS, there has been an issue with the kernel live patching feature becoming unavailable. When compiling the sample code for kernel live patching, the following message is displayed when enabled: livepatch: klp_check_stack: kworker/u256:6:23490 has an unreliable stack Reproduction steps: 1.git checkout v5.4.269 -b v5.4.269 2.make defconfig 3. Set CONFIG_LIVEPATCH=y、CONFIG_SAMPLE_LIVEPATCH=m 4. make -j bzImage 5. make samples/livepatch/livepatch-sample.ko 6. qemu-system-x86_64 -kernel arch/x86_64/boot/bzImage -nographic -append "console=ttyS0" -initrd initrd.img -m 1024M 7. insmod livepatch-sample.ko Kernel live patch cannot complete successfully. After some debugging, the immediate cause of the patch failure is an error in stack checking. The logs are as follows: [ 340.974853] livepatch: klp_check_stack: kworker/u256:0:23486 has an unreliable stack [ 340.974858] livepatch: klp_check_stack: kworker/u256:1:23487 has an unreliable stack [ 340.974863] livepatch: klp_check_stack: kworker/u256:2:23488 has an unreliable stack [ 340.974868] livepatch: klp_check_stack: kworker/u256:5:23489 has an unreliable stack [ 340.974872] livepatch: klp_check_stack: kworker/u256:6:23490 has an unreliable stack ...... BTW,if you use the v5.4.217 tag for testing, make sure to set CONFIG_RETPOLINE = y and CONFIG_LIVEPATCH = y, and other steps are consistent with v5.4.269 After investigation, The problem is strongly related to the commit 8afd1c7da2b0 ("x86/speculation: Change FILL_RETURN_BUFFER to work with objtool"), which would cause incorrect ORC entries to be generated, and the v5.4.217 version can undo this commit to make kernel livepatch work normally. It is a back-ported upstream patch with some code adjustments,from the git log, the author also mentioned no intra-function call validation support. Based on commit 6e1f54a4985b63bc1b55a09e5e75a974c5d6719b (Linux 5.4.269), This patchset adds stack validation support for intra-function calls, allowing the kernel live patching feature to work correctly.

[merged mm-hotfixes-stable] mm-mmap-fix-vma_merge-case-7-with-vma_ops-close.patch removed from -mm tree

The quilt patch titled Subject: mm, mmap: fix vma_merge() case 7 with vma_ops->close has been removed from the -mm tree. Its filename was mm-mmap-fix-vma_merge-case-7-with-vma_ops-close.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: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, mmap: fix vma_merge() case 7 with vma_ops->close Date: Thu, 22 Feb 2024 22:59:31 +0100 When debugging issues with a workload using SysV shmem, Michal Hocko has come up with a reproducer that shows how a series of mprotect() operations can result in an elevated shm_nattch and thus leak of the resource. The problem is caused by wrong assumptions in vma_merge() commit 714965ca8252 ("mm/mmap: start distinguishing if vma can be removed in mergeability test"). The shmem vmas have a vma_ops->close callback that decrements shm_nattch, and we remove the vma without calling it. vma_merge() has thus historically avoided merging vma's with vma_ops->close and commit 714965ca8252 was supposed to keep it that way. It relaxed the checks for vma_ops->close in can_vma_merge_after() assuming that it is never called on a vma that would be a candidate for removal. However, the vma_merge() code does also use the result of this check in the decision to remove a different vma in the merge case 7. A robust solution would be to refactor vma_merge() code in a way that the vma_ops->close check is only done for vma's that are actually going to be removed, and not as part of the preliminary checks. That would both solve the existing bug, and also allow additional merges that the checks currently prevent unnecessarily in some cases. However to fix the existing bug first with a minimized risk, and for easier stable backports, this patch only adds a vma_ops->close check to the buggy case 7 specifically. All other cases of vma removal are covered by the can_vma_merge_before() check that includes the test for vma_ops->close. The reproducer code, adapted from Michal Hocko's code: int main(int argc, char *argv[]) { int segment_id; size_t segment_size = 20 * PAGE_SIZE; char * sh_mem; struct shmid_ds shmid_ds; key_t key = 0x1234; segment_id = shmget(key, segment_size, IPC_CREAT | IPC_EXCL | S_IRUSR | S_IWUSR); sh_mem = (char *)shmat(segment_id, NULL, 0); mprotect(sh_mem + 2*PAGE_SIZE, PAGE_SIZE, PROT_NONE); mprotect(sh_mem + PAGE_SIZE, PAGE_SIZE, PROT_WRITE); mprotect(sh_mem + 2*PAGE_SIZE, PAGE_SIZE, PROT_WRITE); shmdt(sh_mem); shmctl(segment_id, IPC_STAT, &shmid_ds); printf("nattch after shmdt(): %lu (expected: 0)\n", shmid_ds.shm_nattch); if (shmctl(segment_id, IPC_RMID, 0)) printf("IPCRM failed %d\n", errno); return (shmid_ds.shm_nattch) ? 1 : 0; } Link: https://lkml.kernel.org/r/20240222215930.14637-2-vbabka@suse.cz Fixes: 714965ca8252 ("mm/mmap: start distinguishing if vma can be removed in mergeability test") Signed-off-by: Vlastimil Babka <vbabka(a)suse.cz> Reported-by: Michal Hocko <mhocko(a)suse.com> Reviewed-by: Lorenzo Stoakes <lstoakes(a)gmail.com> Reviewed-by: Liam R.

Such combination can happen in a suspend/resume context where a GFP_KERNEL allocation can have __GFP_IO masked out via gfp_allowed_mask. Quoting Sven: 1. try to do a "costly" allocation (order > PAGE_ALLOC_COSTLY_ORDER) with __GFP_RETRY_MAYFAIL set. 2. page alloc's __alloc_pages_slowpath tries to get a page from the freelist. This fails because there is nothing free of that costly order. 3. page alloc tries to reclaim by calling __alloc_pages_direct_reclaim, which bails out because a zone is ready to be compacted; it pretends to have made a single page of progress. 4. page alloc tries to compact, but this always bails out early because __GFP_IO is not set (it's not passed by the snd allocator, and even if it were, we are suspending so the __GFP_IO flag would be cleared anyway). 5. page alloc believes reclaim progress was made (because of the pretense in item 3) and so it checks whether it should retry compaction. The compaction retry logic thinks it should try again, because: a) reclaim is needed because of the early bail-out in item 4 b) a zonelist is suitable for compaction 6. goto 2. indefinite stall. (end quote) The immediate root cause is confusing the COMPACT_SKIPPED returned from __alloc_pages_direct_compact() (step 4) due to lack of __GFP_IO to be indicating a lack of order-0 pages, and in step 5 evaluating that in should_compact_retry() as a reason to retry, before incrementing and limiting the number of retries. There are however other places that wrongly assume that compaction can happen while we lack __GFP_IO. To fix this, introduce gfp_compaction_allowed() to abstract the __GFP_IO evaluation and switch the open-coded test in try_to_compact_pages() to use it. Also use the new helper in: - compaction_ready(), which will make reclaim not bail out in step 3, so there's at least one attempt to actually reclaim, even if chances are small for a costly order - in_reclaim_compaction() which will make should_continue_reclaim() return false and we don't over-reclaim unnecessarily - in __alloc_pages_slowpath() to set a local variable can_compact, which is then used to avoid retrying reclaim/compaction for costly allocations (step 5) if we can't compact and also to skip the early compaction attempt that we do in some cases Link: https://lkml.kernel.org/r/20240221114357.13655-2-vbabka@suse.cz Fixes: 3250845d0526 ("Revert "mm, oom: prevent premature OOM killer invocation for high order request"") Signed-off-by: Vlastimil Babka <vbabka(a)suse.cz> Reported-by: Sven van Ashbrook <svenva(a)chromium.org> Closes: https://lore.kernel.org/all/CAG-rBihs_xMKb3wrMO1%2B-%2Bp4fowP9oy1pa_OTkfxBz… Tested-by: Karthikeyan Ramasubramanian <kramasub(a)chromium.org> Cc: Brian Geffon <bgeffon(a)google.com> Cc: Curtis Malainey <cujomalainey(a)chromium.org> Cc: Jaroslav Kysela <perex(a)perex.cz> Cc: Mel Gorman <mgorman(a)techsingularity.net> Cc: Michal Hocko <mhocko(a)kernel.org> Cc: Takashi Iwai <tiwai(a)suse.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- include/linux/gfp.h | 9 +++++++++ mm/compaction.c | 7 +------ mm/page_alloc.c | 10 ++++++---- mm/vmscan.c | 5 ++++- 4 files changed, 20 insertions(+), 11 deletions(-) --- a/include/linux/gfp.h~mm-vmscan-prevent-infinite-loop-for-costly-gfp_noio-__gfp_retry_mayfail-allocations +++ a/include/linux/gfp.h @@ -353,6 +353,15 @@ static inline bool gfp_has_io_fs(gfp_t g return (gfp & (__GFP_IO | __GFP_FS)) == (__GFP_IO | __GFP_FS);

[PATCH 5.10] xen/events: close evtchn after mapping cleanup

by Andrew Panyakin

From: Maximilian Heyne <mheyne(a)amazon.de> Commit fa765c4b4aed2d64266b694520ecb025c862c5a9 upstream shutdown_pirq and startup_pirq are not taking the irq_mapping_update_lock because they can't due to lock inversion. Both are called with the irq_desc->lock being taking. The lock order, however, is first irq_mapping_update_lock and then irq_desc->lock. This opens multiple races: - shutdown_pirq can be interrupted by a function that allocates an event channel: CPU0 CPU1 shutdown_pirq { xen_evtchn_close(e) __startup_pirq { EVTCHNOP_bind_pirq -> returns just freed evtchn e set_evtchn_to_irq(e, irq) } xen_irq_info_cleanup() { set_evtchn_to_irq(e, -1) } } Assume here event channel e refers here to the same event channel number. After this race the evtchn_to_irq mapping for e is invalid (-1). - __startup_pirq races with __unbind_from_irq in a similar way. Because __startup_pirq doesn't take irq_mapping_update_lock it can grab the evtchn that __unbind_from_irq is currently freeing and cleaning up. In this case even though the event channel is allocated, its mapping can be unset in evtchn_to_irq. The fix is to first cleanup the mappings and then close the event channel. In this way, when an event channel gets allocated it's potential previous evtchn_to_irq mappings are guaranteed to be unset already. This is also the reverse order of the allocation where first the event channel is allocated and then the mappings are setup. On a 5.10 kernel prior to commit 3fcdaf3d7634 ("xen/events: modify internal [un]bind interfaces"), we hit a BUG like the following during probing of NVMe devices. The issue is that during nvme_setup_io_queues, pci_free_irq is called for every device which results in a call to shutdown_pirq. With many nvme devices it's therefore likely to hit this race during boot because there will be multiple calls to shutdown_pirq and startup_pirq are running potentially in parallel. ------------[ cut here ]------------ blkfront: xvda: barrier or flush: disabled; persistent grants: enabled; indirect descriptors: enabled; bounce buffer: enabled kernel BUG at drivers/xen/events/events_base.c:499! invalid opcode: 0000 [#1] SMP PTI CPU: 44 PID: 375 Comm: kworker/u257:23 Not tainted 5.10.201-191.748.amzn2.x86_64 #1 Hardware name: Xen HVM domU, BIOS 4.11.amazon 08/24/2006 Workqueue: nvme-reset-wq nvme_reset_work RIP: 0010:bind_evtchn_to_cpu+0xdf/0xf0 Code: 5d 41 5e c3 cc cc cc cc 44 89 f7 e8 2b 55 ad ff 49 89 c5 48 85 c0 0f 84 64 ff ff ff 4c 8b 68 30 41 83 fe ff 0f 85 60 ff ff ff <0f> 0b 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 0f 1f 44 00 00 RSP: 0000:ffffc9000d533b08 EFLAGS: 00010046 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000006 RDX: 0000000000000028 RSI: 00000000ffffffff RDI: 00000000ffffffff RBP: ffff888107419680 R08: 0000000000000000 R09: ffffffff82d72b00 R10: 0000000000000000 R11: 0000000000000000 R12: 00000000000001ed R13: 0000000000000000 R14: 00000000ffffffff R15: 0000000000000002 FS: 0000000000000000(0000) GS:ffff88bc8b500000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 0000000002610001 CR4: 00000000001706e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? show_trace_log_lvl+0x1c1/0x2d9 ? show_trace_log_lvl+0x1c1/0x2d9 ? set_affinity_irq+0xdc/0x1c0 ? __die_body.cold+0x8/0xd ? die+0x2b/0x50 ? do_trap+0x90/0x110 ? bind_evtchn_to_cpu+0xdf/0xf0 ? do_error_trap+0x65/0x80 ? bind_evtchn_to_cpu+0xdf/0xf0 ? exc_invalid_op+0x4e/0x70 ? bind_evtchn_to_cpu+0xdf/0xf0 ? asm_exc_invalid_op+0x12/0x20 ? bind_evtchn_to_cpu+0xdf/0xf0 ? bind_evtchn_to_cpu+0xc5/0xf0 set_affinity_irq+0xdc/0x1c0 irq_do_set_affinity+0x1d7/0x1f0 irq_setup_affinity+0xd6/0x1a0 irq_startup+0x8a/0xf0 __setup_irq+0x639/0x6d0 ? nvme_suspend+0x150/0x150 request_threaded_irq+0x10c/0x180 ? nvme_suspend+0x150/0x150 pci_request_irq+0xa8/0xf0 ? __blk_mq_free_request+0x74/0xa0 queue_request_irq+0x6f/0x80 nvme_create_queue+0x1af/0x200 nvme_create_io_queues+0xbd/0xf0 nvme_setup_io_queues+0x246/0x320 ? nvme_irq_check+0x30/0x30 nvme_reset_work+0x1c8/0x400 process_one_work+0x1b0/0x350 worker_thread+0x49/0x310 ? process_one_work+0x350/0x350 kthread+0x11b/0x140 ? __kthread_bind_mask+0x60/0x60 ret_from_fork+0x22/0x30 Modules linked in: ---[ end trace a11715de1eee1873 ]--- Fixes: d46a78b05c0e ("xen: implement pirq type event channels") Cc: stable(a)vger.kernel.org Co-debugged-by: Andrew Panyakin <apanyaki(a)amazon.com> Signed-off-by: Maximilian Heyne <mheyne(a)amazon.de> [apanyaki: backport to v5.10-stable] Signed-off-by: Andrew Paniakin <apanyaki(a)amazon.com> --- Compare to upstream patch this one does not have close_evtchn flag because there is no need to handle static event channels.

[PATCH v2] serial: Lock console when calling into driver before registration

by Peter Collingbourne

During the handoff from earlycon to the real console driver, we have two separate drivers operating on the same device concurrently. In the case of the 8250 driver these concurrent accesses cause problems due to the driver's use of banked registers, controlled by LCR.DLAB. It is possible for the setup(), config_port(), pm() and set_mctrl() callbacks to set DLAB, which can cause the earlycon code that intends to access TX to instead access DLL, leading to missed output and corruption on the serial line due to unintended modifications to the baud rate. In particular, for setup() we have: univ8250_console_setup() -> serial8250_console_setup() -> uart_set_options() -> serial8250_set_termios() -> serial8250_do_set_termios() -> serial8250_do_set_divisor() For config_port() we have: serial8250_config_port() -> autoconfig() For pm() we have: serial8250_pm() -> serial8250_do_pm() -> serial8250_set_sleep() For set_mctrl() we have (for some devices): serial8250_set_mctrl() -> omap8250_set_mctrl() -> __omap8250_set_mctrl() To avoid such problems, let's make it so that the console is locked during pre-registration calls to these callbacks, which will prevent the earlycon driver from running concurrently. Remove the partial solution to this problem in the 8250 driver that locked the console only during autoconfig_irq(), as this would result in a deadlock with the new approach. The console continues to be locked during autoconfig_irq() because it can only be called through uart_configure_port(). Although this patch introduces more locking than strictly necessary (and in particular it also locks during the call to rs485_config() which is not affected by this issue as far as I can tell), it follows the principle that it is the responsibility of the generic console code to manage the earlycon handoff by ensuring that earlycon and real console driver code cannot run concurrently, and not the individual drivers.

[PATCH 5.15] xen/events: close evtchn after mapping cleanup

by Andrew Panyakin

From: Maximilian Heyne <mheyne(a)amazon.de> Commit fa765c4b4aed2d64266b694520ecb025c862c5a9 upstream shutdown_pirq and startup_pirq are not taking the irq_mapping_update_lock because they can't due to lock inversion. Both are called with the irq_desc->lock being taking. The lock order, however, is first irq_mapping_update_lock and then irq_desc->lock. This opens multiple races: - shutdown_pirq can be interrupted by a function that allocates an event channel: CPU0 CPU1 shutdown_pirq { xen_evtchn_close(e) __startup_pirq { EVTCHNOP_bind_pirq -> returns just freed evtchn e set_evtchn_to_irq(e, irq) } xen_irq_info_cleanup() { set_evtchn_to_irq(e, -1) } } Assume here event channel e refers here to the same event channel number. After this race the evtchn_to_irq mapping for e is invalid (-1). - __startup_pirq races with __unbind_from_irq in a similar way. Because __startup_pirq doesn't take irq_mapping_update_lock it can grab the evtchn that __unbind_from_irq is currently freeing and cleaning up. In this case even though the event channel is allocated, its mapping can be unset in evtchn_to_irq. The fix is to first cleanup the mappings and then close the event channel. In this way, when an event channel gets allocated it's potential previous evtchn_to_irq mappings are guaranteed to be unset already. This is also the reverse order of the allocation where first the event channel is allocated and then the mappings are setup. On a 5.10 kernel prior to commit 3fcdaf3d7634 ("xen/events: modify internal [un]bind interfaces"), we hit a BUG like the following during probing of NVMe devices. The issue is that during nvme_setup_io_queues, pci_free_irq is called for every device which results in a call to shutdown_pirq. With many nvme devices it's therefore likely to hit this race during boot because there will be multiple calls to shutdown_pirq and startup_pirq are running potentially in parallel. ------------[ cut here ]------------ blkfront: xvda: barrier or flush: disabled; persistent grants: enabled; indirect descriptors: enabled; bounce buffer: enabled kernel BUG at drivers/xen/events/events_base.c:499! invalid opcode: 0000 [#1] SMP PTI CPU: 44 PID: 375 Comm: kworker/u257:23 Not tainted 5.10.201-191.748.amzn2.x86_64 #1 Hardware name: Xen HVM domU, BIOS 4.11.amazon 08/24/2006 Workqueue: nvme-reset-wq nvme_reset_work RIP: 0010:bind_evtchn_to_cpu+0xdf/0xf0 Code: 5d 41 5e c3 cc cc cc cc 44 89 f7 e8 2b 55 ad ff 49 89 c5 48 85 c0 0f 84 64 ff ff ff 4c 8b 68 30 41 83 fe ff 0f 85 60 ff ff ff <0f> 0b 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 0f 1f 44 00 00 RSP: 0000:ffffc9000d533b08 EFLAGS: 00010046 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000006 RDX: 0000000000000028 RSI: 00000000ffffffff RDI: 00000000ffffffff RBP: ffff888107419680 R08: 0000000000000000 R09: ffffffff82d72b00 R10: 0000000000000000 R11: 0000000000000000 R12: 00000000000001ed R13: 0000000000000000 R14: 00000000ffffffff R15: 0000000000000002 FS: 0000000000000000(0000) GS:ffff88bc8b500000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 0000000002610001 CR4: 00000000001706e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? show_trace_log_lvl+0x1c1/0x2d9 ? show_trace_log_lvl+0x1c1/0x2d9 ? set_affinity_irq+0xdc/0x1c0 ? __die_body.cold+0x8/0xd ? die+0x2b/0x50 ? do_trap+0x90/0x110 ? bind_evtchn_to_cpu+0xdf/0xf0 ? do_error_trap+0x65/0x80 ? bind_evtchn_to_cpu+0xdf/0xf0 ? exc_invalid_op+0x4e/0x70 ? bind_evtchn_to_cpu+0xdf/0xf0 ? asm_exc_invalid_op+0x12/0x20 ? bind_evtchn_to_cpu+0xdf/0xf0 ? bind_evtchn_to_cpu+0xc5/0xf0 set_affinity_irq+0xdc/0x1c0 irq_do_set_affinity+0x1d7/0x1f0 irq_setup_affinity+0xd6/0x1a0 irq_startup+0x8a/0xf0 __setup_irq+0x639/0x6d0 ? nvme_suspend+0x150/0x150 request_threaded_irq+0x10c/0x180 ? nvme_suspend+0x150/0x150 pci_request_irq+0xa8/0xf0 ? __blk_mq_free_request+0x74/0xa0 queue_request_irq+0x6f/0x80 nvme_create_queue+0x1af/0x200 nvme_create_io_queues+0xbd/0xf0 nvme_setup_io_queues+0x246/0x320 ? nvme_irq_check+0x30/0x30 nvme_reset_work+0x1c8/0x400 process_one_work+0x1b0/0x350 worker_thread+0x49/0x310 ? process_one_work+0x350/0x350 kthread+0x11b/0x140 ? __kthread_bind_mask+0x60/0x60 ret_from_fork+0x22/0x30 Modules linked in: ---[ end trace a11715de1eee1873 ]--- Fixes: d46a78b05c0e ("xen: implement pirq type event channels") Cc: stable(a)vger.kernel.org Co-debugged-by: Andrew Panyakin <apanyaki(a)amazon.com> Signed-off-by: Maximilian Heyne <mheyne(a)amazon.de> [apanyaki: backport to v5.15-stable] Signed-off-by: Andrew Paniakin <apanyaki(a)amazon.com> --- Compare to upstream patch this one does not have close_evtchn flag because there is no need to handle static event channels.

[PATCH stable v6.7] drm/nouveau: don't fini scheduler before entity flush

by Danilo Krummrich

This bug is present in v6.7 only, since the scheduler design has been re-worked in v6.8. Client scheduler entities must be flushed before an associated GPU scheduler is teared down.

[PATCH] btrfs: qgroup: verify btrfs_qgroup_inherit parameter

by Qu Wenruo

[BUG] Currently btrfs can create subvolume with an invalid qgroup inherit without triggering any error: # mkfs.btrfs -O quota -f $dev # mount $dev $mnt # btrfs subvolume create -i 2/0 $mnt/subv1 # btrfs qgroup show -prce --sync $mnt Qgroupid Referenced Exclusive Path -------- ---------- --------- ---- 0/5 16.00KiB 16.00KiB <toplevel> 0/256 16.00KiB 16.00KiB subv1 [CAUSE] We only do a very basic size check for btrfs_qgroup_inherit structure, but never really verify if the values are correct. Thus in btrfs_qgroup_inherit() function, we have to skip non-existing qgroups, and never return any error. [FIX] Fix the behavior and introduce extra checks: - Introduce early check for btrfs_qgroup_inherit structure Not only the size, but also all the qgroup ids would be verifyed. And the timing is very early, so we can return error early. This early check is very important for snapshot creation, as snapshot is delayed to transaction commit. - Drop support for btrfs_qgroup_inherit::num_ref_copies and num_excl_copies Those two members are used to specify to copy refr/excl numbers from other qgroups. This would definitely mark qgroup inconsistent, and btrfs-progs has dropped the support for them for a long time. It's time to drop the support for kernel. - Verify the supported btrfs_qgroup_inherit::flags Just in case we want to add extra flags for btrfs_qgroup_inherit. Now above subvolume creation would fail with -ENOENT other than silently ignore the non-existing qgroup.

[PATCH 6.7.y v2 0/5] Delay VERW - 6.7.y backport

by Pawan Gupta

v2: - Dropped already backported patch "x86/bugs: Add asm helpers for executing VERW". https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… - Boot tested with KASLR and KPTI enabled. - Rebased to v6.7.8 v1: https://lore.kernel.org/r/20240226-delay-verw-backport-6-7-y-v1-0-ab25f6431… This is the backport of recently upstreamed series that moves VERW execution to a later point in exit-to-user path. This is needed because in some cases it may be possible for data accessed after VERW executions may end into MDS affected CPU buffers. Moving VERW closer to ring transition reduces the attack surface. Patch 2/7: A conflict was resolved for the hunk swapgs_restore_regs_and_return_to_usermode.

[PATCH net 0/2] selftests: mptcp: fixes for diag.sh

Here are two patches fixing issues in MPTCP diag.sh kselftest: - Patch 1 makes sure the exit code is '1' in case of error, and not the test ID, not to return an exit code that would be wrongly interpreted by the ksefltests framework, e.g. '4' means 'skip'. - Patch 2 avoids waiting for unnecessary conditions, which can cause timeouts in some very slow environments.

[PATCH stable 6.1] NFS: Fix data corruption caused by congestion.

by NeilBrown

when AOP_WRITEPAGE_ACTIVATE is returned (as NFS does when it detects congestion) it is important that the page is redirtied. nfs_writepage_locked() doesn't do this, so files can become corrupted as writes can be lost. Note that this is not needed in v6.8 as AOP_WRITEPAGE_ACTIVATE cannot be returned. It is needed for kernels v5.18..v6.7. From 6.3 onward the patch is different as it needs to mention "folio", not "page".

[REGRESSION][PATCH 5.15 v1] Revert "drm/bridge: lt8912b: Register and attach our DSI device at probe"

by max.oss.09＠gmail.com

From: Max Krummenacher <max.krummenacher(a)toradex.com> This reverts commit ef4a40953c8076626875ff91c41e210fcee7a6fd. The commit was applied to make further commits apply cleanly, but the commit depends on other commits in the same patchset. I.e. the controlling DSI host would need a change too. Thus one would need to backport the full patchset changing the DSI hosts and all downstream DSI device drivers. Revert the commit and fix up the conflicts with the backported fixes to the lt8912b driver.

EFI/x86 backports for v6.1

by Ard Biesheuvel

Please consider the patches below for backporting to v6.1. They should all apply cleanly in the given order. These are prerequisites for NX compat support on x86, but the remaining changes do not apply cleanly and will be sent as a patch series at a later date. By themselves, these changes not only constitute a reasonable cleanup, they are also needed for future support of x86s [0] CPUs that are no longer able to transition out of long mode.

[PATCH v5.15-v5.4] fs,hugetlb: fix NULL pointer dereference in hugetlbs_fill_super

by Vamsi Krishna Brahmajosyula

From: Oscar Salvador <osalvador(a)suse.de> commit 79d72c68c58784a3e1cd2378669d51bfd0cb7498 upstream. 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] mm/huge_memory: fix swap entry values of tail pages of THP

by Charan Teja Kalla

An anon THP page is first added to swap cache before reclaiming it. Initially, each tail page contains the proper swap entry value(stored in ->private field) which is filled from add_to_swap_cache(). After migrating the THP page sitting on the swap cache, only the swap entry of the head page is filled(see folio_migrate_mapping()). Now when this page is tried to split(one case is when this page is again migrated, see migrate_pages()->try_split_thp()), the tail pages ->private is not stored with proper swap entry values. When this tail page is now try to be freed, as part of it delete_from_swap_cache() is called which operates on the wrong swap cache index and eventually replaces the wrong swap cache index with shadow/NULL value, frees the page. This leads to the state with a swap cache containing the freed page. This issue can manifest in many forms and the most common thing observed is the rcu stall during the swapin (see mapping_get_entry()). On the recent kernels, this issues is indirectly getting fixed with the series[1], to be specific[2]. When tried to back port this series, it is observed many merge conflicts and also seems dependent on many other changes. As backporting to LTS branches is not a trivial one, the similar change from [2] is picked as a fix.

Please apply commit 5b750b22530fe53bf7fd6a30baacd53ada26911b to linux-6.1.y

by Nathan Chancellor

Hi Greg and Sasha, Please apply upstream commit 5b750b22530f ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml") to linux-6.1.y, as it is needed to avoid instances of -Wframe-larger-than in allmodconfig, which has -Werror enabled. It applies cleanly for me and it is already in 6.6 and 6.7. The fixes tag is not entirely accurate and commit e63e35f0164c ("drm/amd/display: Increase frame-larger-than for all display_mode_vba files"), which was recently applied to that tree, depends on it (I should have made that clearer in the patch). If there are any issues, please let me know. Cheers, Nathan

[PATCH v3 0/5] Pinephone video out fixes (flipping between two frames)

by Frank Oltmanns

On some pinephones the video output sometimes freezes (flips between two frames) [1]. It seems to be that the reason for this behaviour is that PLL-MIPI is outside its limits, and the GPU is not running at a fixed rate. In this patch series I propose the following changes: 1. sunxi-ng: Adhere to the following constraints given in the Allwinner A64 Manual regarding PLL-MIPI: * M/N <= 3 * (PLL_VIDEO0)/M >= 24MHz * 500MHz <= clockrate <= 1400MHz 2. Remove two operating points from the A64 DTS OPPs, so that the GPU runs at a fixed rate of 432 MHz. Note, that when pinning the GPU to 432 MHz the issue [1] completely disappears for me. I've searched the BSP and could not find any indication that supports the idea of having the three OPPs. The only frequency I found in the BPSs for A64 is 432 MHz, which has also proven stable for me. Another bigger change compared to the previous version is that I've removed the patch to adapt the XBD599 panel's timings to Allwinner A64's PLL-MIPI new constraints from this series. Mainly, because I'm currently evaluationg other options that may or may not work. (It may work at least until HDMI support is upstreamed.) I'll probably resend the patch at a later point in time. I very much appreciate your feedback!

Backport fix for CVE-2023-2176 (8d037973 and 0e158630) to v6.1

by Brennan Lamoreaux

Hi stable maintainers, The following patch in mainline is listed as a fix for CVE-2023-2176: 8d037973d48c026224ab285e6a06985ccac6f7bf (RDMA/core: Refactor rdma_bind_addr) And the following is a fix for a regression in the above patch: 0e15863015d97c1ee2cc29d599abcc7fa2dc3e95 (RDMA/core: Update CMA destination address on rdma_resolve_addr) To my knowledge, at least back to v6.1 is vulnerable to this same bug. Since these should apply directly to 6.1.y, can these be picked up for that branch? Regards, Brennan

[PATCH 6.1.y v2 0/6] Delay VERW - 6.1.y backport

by Pawan Gupta

v2: - Runtime patch jmp instead of verw in macro CLEAR_CPU_BUFFERS due to lack of relative addressing support in relocations in kernels <v6.5. - Rebased to v6.1.80 - Boot tested with KASLR and KPTI enabled. - Fixed warning: arch/x86/entry/entry.o: warning: objtool: mds_verw_sel+0x0: unreachable instruction - Verified VERW being executed with mitigation ON, and not being executed with mitigation turned OFF. - Rebased to v6.1.80. v1: https://lore.kernel.org/r/20240226-delay-verw-backport-6-1-y-v1-0-b3a2c5b9b… This is the backport of recently upstreamed series that moves VERW execution to a later point in exit-to-user path. This is needed because in some cases it may be possible for data accessed after VERW executions may end into MDS affected CPU buffers. Moving VERW closer to ring transition reduces the attack surface. Patch 1/6 includes a minor fix that is queued for upstream: https://lore.kernel.org/lkml/170899674562.398.6398007479766564897.tip-bot2@… Patch 1,2,5 and 6 needed conflict resolution. I saw a few new warnings: arch/x86/entry/entry.o: warning: objtool: mds_verw_sel+0x0: unreachable instruction I tried using REACHABLE, but that did not fix the warning. For the below warning: vmlinux.o: warning: objtool: .altinstr_replacement+0x17: unsupported relocation in alternatives section not sure if this is related to this series or a pre-existing warning, I will check later without this series.

[PATCH v3] i2c: acpi: Unbind mux adapters before delete

by Hamish Martin

There is an issue with ACPI overlay table removal specifically related to I2C multiplexers. Consider an ACPI SSDT Overlay that defines a PCA9548 I2C mux on an existing I2C bus. When this table is loaded we see the creation of a device for the overall PCA9548 chip and 8 further devices - one i2c_adapter each for the mux channels. These are all bound to their ACPI equivalents via an eventual invocation of acpi_bind_one(). When we unload the SSDT overlay we run into the problem. The ACPI devices are deleted as normal via acpi_device_del_work_fn() and the acpi_device_del_list. However, the following warning and stack trace is output as the deletion does not go smoothly: ------------[ cut here ]------------ kernfs: can not remove 'physical_node', no directory WARNING: CPU: 1 PID: 11 at fs/kernfs/dir.c:1674 kernfs_remove_by_name_ns+0xb9/0xc0 Modules linked in: CPU: 1 PID: 11 Comm: kworker/u128:0 Not tainted 6.8.0-rc6+ #1 Hardware name: congatec AG conga-B7E3/conga-B7E3, BIOS 5.13 05/16/2023 Workqueue: kacpi_hotplug acpi_device_del_work_fn RIP: 0010:kernfs_remove_by_name_ns+0xb9/0xc0 Code: e4 00 48 89 ef e8 07 71 db ff 5b b8 fe ff ff ff 5d 41 5c 41 5d e9 a7 55 e4 00 0f 0b eb a6 48 c7 c7 f0 38 0d 9d e8 97 0a d5 ff <0f> 0b eb dc 0f 1f 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 RSP: 0018:ffff9f864008fb28 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff8ef90a8d4940 RCX: 0000000000000000 RDX: ffff8f000e267d10 RSI: ffff8f000e25c780 RDI: ffff8f000e25c780 RBP: ffff8ef9186f9870 R08: 0000000000013ffb R09: 00000000ffffbfff R10: 00000000ffffbfff R11: ffff8f000e0a0000 R12: ffff9f864008fb50 R13: ffff8ef90c93dd60 R14: ffff8ef9010d0958 R15: ffff8ef9186f98c8 FS: 0000000000000000(0000) GS:ffff8f000e240000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f48f5253a08 CR3: 00000003cb82e000 CR4: 00000000003506f0 Call Trace: <TASK> ? kernfs_remove_by_name_ns+0xb9/0xc0 ? __warn+0x7c/0x130 ? kernfs_remove_by_name_ns+0xb9/0xc0 ? report_bug+0x171/0x1a0 ? handle_bug+0x3c/0x70 ? exc_invalid_op+0x17/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? kernfs_remove_by_name_ns+0xb9/0xc0 ? kernfs_remove_by_name_ns+0xb9/0xc0 acpi_unbind_one+0x108/0x180 device_del+0x18b/0x490 ? srso_return_thunk+0x5/0x5f ? srso_return_thunk+0x5/0x5f device_unregister+0xd/0x30 i2c_del_adapter.part.0+0x1bf/0x250 i2c_mux_del_adapters+0xa1/0xe0 i2c_device_remove+0x1e/0x80 device_release_driver_internal+0x19a/0x200 bus_remove_device+0xbf/0x100 device_del+0x157/0x490 ? __pfx_device_match_fwnode+0x10/0x10 ? srso_return_thunk+0x5/0x5f device_unregister+0xd/0x30 i2c_acpi_notify+0x10f/0x140 notifier_call_chain+0x58/0xd0 blocking_notifier_call_chain+0x3a/0x60 acpi_device_del_work_fn+0x85/0x1d0 process_one_work+0x134/0x2f0 worker_thread+0x2f0/0x410 ? __pfx_worker_thread+0x10/0x10 kthread+0xe3/0x110 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x2f/0x50 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1b/0x30 </TASK> ---[ end trace 0000000000000000 ]--- ... repeated 7 more times, 1 for each channel of the mux ... The issue is that the binding of the ACPI devices to their peer I2C adapters is not correctly cleaned up. Digging deeper into the issue we see that the deletion order is such that the ACPI devices matching the mux channel i2c adapters are deleted first during the SSDT overlay removal. For each of the channels we see a call to i2c_acpi_notify() with ACPI_RECONFIG_DEVICE_REMOVE but, because these devices are not actually i2c_clients, nothing is done for them. Later on, after each of the mux channels has been dealt with, we come to delete the i2c_client representing the PCA9548 device. This is the call stack we see above, whereby the kernel cleans up the i2c_client including destruction of the mux and its channel adapters. At this point we do attempt to unbind from the ACPI peers but those peers no longer exist and so we hit the kernfs errors. The fix is to augment i2c_acpi_notify() to handle i2c_adapters. But, given that the life cycle of the adapters is linked to the i2c_client, instead of deleting the i2c_adapters during the i2c_acpi_notify(), we just trigger unbinding of the ACPI device from the adapter device, and allow the clean up of the adapter to continue in the way it always has.

[PATCH 6.1.y] mptcp: continue marking the first subflow as UNCONNECTED

by Matthieu Baerts (NGI0)

After the 'Fixes' commit mentioned below, which is a partial backport, the MPTCP worker was no longer marking the first subflow as "UNCONNECTED" when the socket was transitioning to TCP_CLOSE state. As a result, in v6.1, it was no longer possible to reconnect to the just disconnected socket. Continue to do that like before, only for the first subflow. A few refactoring have been done around the 'msk->subflow' in later versions, and it looks like this is not needed to do that there, but still needed in v6.1. Without that, the 'disconnect' tests from the mptcp_connect.sh selftest fail: they repeat the transfer 3 times by reconnecting to the server each time.

However, bits in this CSR are defined by several other extensions which may be implemented separately from any particular version of the privileged ISA (for example, some unrelated errata may prevent an implementation from claiming conformance with Ss1p12). As a result, Linux cannot simply use the privileged ISA version to determine if the CSR is present. It must also check if any of these other extensions are implemented. It also cannot probe the existence of the CSR at runtime, because Linux does not require Sstrict, so (in the absence of additional information) it cannot know if a CSR at that address is [ms]envcfg or part of some non-conforming vendor extension. Since there are several standard extensions that imply the existence of the [ms]envcfg CSR, it becomes unwieldy to check for all of them wherever the CSR is accessed. Instead, define a custom Xlinuxenvcfg ISA extension bit that is implied by the other extensions and denotes that the CSR exists as defined in the privileged ISA, containing at least one of the fields common between menvcfg and senvcfg. This extension does not need to be parsed from the devicetree or ISA string because it can only be implemented as a subset of some other standard extension.

These macros eventually use __builtin_return_address(n) to get the caller's address if arch doesn't define their own implementation. In RISC-V, __builtin_return_address(n) only works when n == 0, we need to walk the stack frame to get the caller's address at specified level. data.level started from 'level + 3' due to the call flow of getting caller's address in RISC-V implementation. If we don't have additional three iteration, the level is corresponding to follows: callsite -> return_address -> arch_stack_walk -> walk_stackframe | | | | level 3 level 2 level 1 level 0 Fixes: 10626c32e382 ("riscv/ftrace: Add basic support") Cc: stable(a)vger.kernel.org Reviewed-by: Alexandre Ghiti <alexghiti(a)rivosinc.com> Signed-off-by: Zong Li <zong.li(a)sifive.com> Link: https://lore.kernel.org/r/20240202015102.26251-1-zong.li@sifive.com Signed-off-by: Palmer Dabbelt <palmer(a)rivosinc.com> diff --git a/arch/riscv/include/asm/ftrace.h b/arch/riscv/include/asm/ftrace.h index 329172122952..15055f9df4da 100644 --- a/arch/riscv/include/asm/ftrace.h +++ b/arch/riscv/include/asm/ftrace.h @@ -25,6 +25,11 @@ #define ARCH_SUPPORTS_FTRACE_OPS 1 #ifndef __ASSEMBLY__ + +extern void *return_address(unsigned int level); + +#define ftrace_return_address(n) return_address(n) + void MCOUNT_NAME(void); static inline unsigned long ftrace_call_adjust(unsigned long addr) { diff --git a/arch/riscv/kernel/Makefile b/arch/riscv/kernel/Makefile index f71910718053..604d6bf7e476 100644 --- a/arch/riscv/kernel/Makefile +++ b/arch/riscv/kernel/Makefile @@ -7,6 +7,7 @@ ifdef CONFIG_FTRACE CFLAGS_REMOVE_ftrace.o = $(CC_FLAGS_FTRACE) CFLAGS_REMOVE_patch.o = $(CC_FLAGS_FTRACE) CFLAGS_REMOVE_sbi.o = $(CC_FLAGS_FTRACE) +CFLAGS_REMOVE_return_address.o = $(CC_FLAGS_FTRACE) endif CFLAGS_syscall_table.o += $(call cc-option,-Wno-override-init,) CFLAGS_compat_syscall_table.o += $(call cc-option,-Wno-override-init,) @@ -46,6 +47,7 @@ obj-y += irq.o obj-y += process.o obj-y += ptrace.o obj-y += reset.o +obj-y += return_address.o obj-y += setup.o obj-y += signal.o obj-y += syscall_table.o diff --git a/arch/riscv/kernel/return_address.c b/arch/riscv/kernel/return_address.c new file mode 100644 index 000000000000..c8115ec8fb30 --- /dev/null +++ b/arch/riscv/kernel/return_address.c @@ -0,0 +1,48 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * This code come from arch/arm64/kernel/return_address.c + * + * Copyright (C) 2023 SiFive. + */ + +#include <linux/export.h> +#include <linux/kprobes.h> +#include <linux/stacktrace.h> + +struct return_address_data { + unsigned int level; + void *addr; +}; + +static bool save_return_addr(void *d, unsigned long pc) +{ + struct return_address_data *data = d; + + if (!data->level) { + data->addr = (void *)pc; + return false; + } + + --data->level; + + return true; +} +NOKPROBE_SYMBOL(save_return_addr); + +noinline void *return_address(unsigned int level) +{ + struct return_address_data data; + + data.level = level + 3; + data.addr = NULL; + + arch_stack_walk(save_return_addr, &data, current, NULL); + + if (!data.level) + return data.addr; + else + return NULL; + +} +EXPORT_SYMBOL_GPL(return_address); +NOKPROBE_SYMBOL(return_address);

[PATCH regression fix] misc: lis3lv02d_i2c: Fix regulators getting en-/dis-abled twice on suspend/resume

by Hans de Goede

When not configured for wakeup lis3lv02d_i2c_suspend() will call lis3lv02d_poweroff() even if the device has already been turned off by the runtime-suspend handler and if configured for wakeup and the device is runtime-suspended at this point then it is not turned back on to serve as a wakeup source. Before commit b1b9f7a49440 ("misc: lis3lv02d_i2c: Add missing setting of the reg_ctrl callback"), lis3lv02d_poweroff() failed to disable the regulators which as a side effect made calling poweroff() twice ok. Now that poweroff() correctly disables the regulators, doing this twice triggers a WARN() in the regulator core: unbalanced disables for regulator-dummy WARNING: CPU: 1 PID: 92 at drivers/regulator/core.c:2999 _regulator_disable ... Fix lis3lv02d_i2c_suspend() to not call poweroff() a second time if already runtime-suspended and add a poweron() call when necessary to make wakeup work. lis3lv02d_i2c_resume() has similar issues, with an added weirness that it always powers on the device if it is runtime suspended, after which the first runtime-resume will call poweron() again, causing the enabled count for the regulator to increase by 1 every suspend/resume. These unbalanced regulator_enable() calls cause the regulator to never be turned off and trigger the following WARN() on driver unbind: WARNING: CPU: 1 PID: 1724 at drivers/regulator/core.c:2396 _regulator_put Fix this by making lis3lv02d_i2c_resume() mirror the new suspend().

A few months later, the much delayed addition of max_xattr_size got merged, also with encoding version 17, placed before bal_rank_mask in the encoding -- but it didn't make v18.2.0 release. The way this ended up being resolved on the MDS side is that bal_rank_mask will continue to be encoded in version 17 while max_xattr_size is now encoded in version 18. This does mean that older kernels will misdecode version 17, but this is also true for v18.2.0 and v18.2.1 clients in userspace.

This has manifested itself as the display subsystem occasionally failing to initialise and NULL-pointer dereferences during boot of machines like the Lenovo ThinkPad X13s. Specifically, the dp-hpd bridge is currently registered before all resources have been acquired which means that it can also be deregistered on probe deferrals. In the meantime there is a race window where the new aux bridge driver (or PHY driver previously) may have looked up the dp-hpd bridge and stored a (non-reference-counted) pointer to the bridge which is about to be deallocated. When the display controller is later initialised, this triggers a use-after-free when attaching the bridges: dp -> aux -> dp-hpd (freed) which may, for example, result in the freed bridge failing to attach: [drm:drm_bridge_attach [drm]] *ERROR* failed to attach bridge /soc@0/phy@88eb000 to encoder TMDS-31: -16 or a NULL-pointer dereference: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 ...

In this case, the fix is to move the bridge registration in the pmic_glink_altmode driver to after all resources have been looked up. Incidentally, with the new dp-hpd bridge implementation, which registers child devices, this is also a requirement due to a long-standing issue in driver core that can otherwise lead to a probe deferral loop (see commit fbc35b45f9f6 ("Add documentation on meaning of -EPROBE_DEFER")).

In the meantime there is a race window where the new aux bridge driver (or PHY driver previously) may have looked up the dp-hpd bridge and stored a (non-reference-counted) pointer to the bridge which is about to be deallocated. When the display controller is later initialised, this triggers a use-after-free when attaching the bridges: dp -> aux -> dp-hpd (freed) which may, for example, result in the freed bridge failing to attach: [drm:drm_bridge_attach [drm]] *ERROR* failed to attach bridge /soc@0/phy@88eb000 to encoder TMDS-31: -16 or a NULL-pointer dereference: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 ...

In this case, the fix is to move the bridge registration in the pmic_glink_altmode driver to after all resources have been looked up. Incidentally, with the new dp-hpd bridge implementation, which registers child devices, this is also a requirement due to a long-standing issue in driver core that can otherwise lead to a probe deferral loop (see commit fbc35b45f9f6 ("Add documentation on meaning of -EPROBE_DEFER")).

The second free may result in freeing an anonymous device number that was allocated by some other subsystem in the kernel or another btrfs filesystem. The steps that lead to this: 1) At ioctl.c:create_snapshot() we allocate an anonymous device number and assign it to pending_snapshot->anon_dev; 2) Then we call btrfs_commit_transaction() and end up at transaction.c:create_pending_snapshot(); 3) There we call btrfs_get_new_fs_root() and pass it the anonymous device number stored in pending_snapshot->anon_dev; 4) btrfs_get_new_fs_root() frees that anonymous device number because btrfs_lookup_fs_root() returned a root - someone else did a lookup of the new root already, which could some task doing backref walking; 5) After that some error happens in the transaction commit path, and at ioctl.c:create_snapshot() we jump to the 'fail' label, and after that we free again the same anonymous device number, which in the meanwhile may have been reallocated somewhere else, because pending_snapshot->anon_dev still has the same value as in step 1.

It happens in a different code path from the example below, at btrfs_get_root_ref(), so this change may not fix the case triggered by syzbot. To fix at least the code path from the example above, change btrfs_get_root_ref() and its callers to receive a dev_t pointer argument for the anonymous device number, so that in case it frees the number, it also resets it to 0, so that up in the call chain we don't attempt to do the double free.

The second free may result in freeing an anonymous device number that was allocated by some other subsystem in the kernel or another btrfs filesystem. The steps that lead to this: 1) At ioctl.c:create_snapshot() we allocate an anonymous device number and assign it to pending_snapshot->anon_dev; 2) Then we call btrfs_commit_transaction() and end up at transaction.c:create_pending_snapshot(); 3) There we call btrfs_get_new_fs_root() and pass it the anonymous device number stored in pending_snapshot->anon_dev; 4) btrfs_get_new_fs_root() frees that anonymous device number because btrfs_lookup_fs_root() returned a root - someone else did a lookup of the new root already, which could some task doing backref walking; 5) After that some error happens in the transaction commit path, and at ioctl.c:create_snapshot() we jump to the 'fail' label, and after that we free again the same anonymous device number, which in the meanwhile may have been reallocated somewhere else, because pending_snapshot->anon_dev still has the same value as in step 1.

It happens in a different code path from the example below, at btrfs_get_root_ref(), so this change may not fix the case triggered by syzbot. To fix at least the code path from the example above, change btrfs_get_root_ref() and its callers to receive a dev_t pointer argument for the anonymous device number, so that in case it frees the number, it also resets it to 0, so that up in the call chain we don't attempt to do the double free.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From bd03a3e4c9a9df0c6b007045fa7fc8889111a478 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa <penguin-kernel(a)I-love.SAKURA.ne.jp> Date: Sun, 26 Jun 2011 23:19:52 +0900 Subject: [PATCH] TOMOYO: Add policy namespace support. Mauras Olivier reported that it is difficult to use TOMOYO in LXC environments, for TOMOYO cannot distinguish between environments outside the container and environments inside the container since LXC environments are created using pivot_root(). To address this problem, this patch introduces policy namespace. Each policy namespace has its own set of domain policy, exception policy and profiles, which are all independent of other namespaces. This independency allows users to develop policy without worrying interference among namespaces.

Possible dependencies: thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From bd03a3e4c9a9df0c6b007045fa7fc8889111a478 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa <penguin-kernel(a)I-love.SAKURA.ne.jp> Date: Sun, 26 Jun 2011 23:19:52 +0900 Subject: [PATCH] TOMOYO: Add policy namespace support. Mauras Olivier reported that it is difficult to use TOMOYO in LXC environments, for TOMOYO cannot distinguish between environments outside the container and environments inside the container since LXC environments are created using pivot_root(). To address this problem, this patch introduces policy namespace. Each policy namespace has its own set of domain policy, exception policy and profiles, which are all independent of other namespaces. This independency allows users to develop policy without worrying interference among namespaces.

[PATCH 6.6.y v2 0/5] Delay VERW - 6.6.y backport

by Pawan Gupta

v2: - Dropped already backported patch "x86/bugs: Add asm helpers for executing VERW" https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… - Booted fine with KASLR and KPTI enabled. - Rebased to v6.6.20 v1: https://lore.kernel.org/r/20240226-delay-verw-backport-6-6-y-v1-0-aa17b2922… This is the backport of recently upstreamed series that moves VERW execution to a later point in exit-to-user path. This is needed because in some cases it may be possible for data accessed after VERW executions may end into MDS affected CPU buffers. Moving VERW closer to ring transition reduces the attack surface. Patch 1/6 includes a minor fix that is queued for upstream: https://lore.kernel.org/lkml/170899674562.398.6398007479766564897.tip-bot2@… Patch 2/6 needed a conflict to be resolved for the hunk swapgs_restore_regs_and_return_to_usermode. This is only compile and boot tested on qemu.

[PATCH] serial: 8250_dw: Do not reclock if already at correct rate

by Peter Collingbourne

When userspace opens the console, we call set_termios() passing a termios with the console's configured baud rate. Currently this causes dw8250_set_termios() to disable and then re-enable the UART clock at the same frequency as it was originally. This can cause corruption of any concurrent console output. Fix it by skipping the reclocking if we are already at the correct rate.

patch "iio: adc: rockchip_saradc: use mask for write_enable bitfield" added to char-misc-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: adc: rockchip_saradc: use mask for write_enable bitfield to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. From 5b4e4b72034f85f7a0cdd147d3d729c5a22c8764 Mon Sep 17 00:00:00 2001 From: Quentin Schulz <quentin.schulz(a)theobroma-systems.com> Date: Fri, 23 Feb 2024 13:45:22 +0100 Subject: iio: adc: rockchip_saradc: use mask for write_enable bitfield Some of the registers on the SARADCv2 have bits write protected except if another bit is set. This is usually done by having the lowest 16 bits store the data to write and the highest 16 bits specify which of the 16 lowest bits should have their value written to the hardware block. The write_enable mask for the channel selection was incorrect because it was just the value shifted by 16 bits, which means it would only ever write bits and never clear them. So e.g. if someone starts a conversion on channel 5, the lowest 4 bits would be 0x5, then starts a conversion on channel 0, it would still be 5. Instead of shifting the value by 16 as the mask, let's use the OR'ing of the appropriate masks shifted by 16. Note that this is not an issue currently because the only SARADCv2 currently supported has a reset defined in its Device Tree, that reset resets the SARADC controller before starting a conversion on a channel. However, this reset is handled as optional by the probe function and thus proper masking should be used in the event an SARADCv2 without a reset ever makes it upstream.

[PATCH v2] usb: port: Don't try to peer unused USB ports based on location

by Mathias Nyman

Unused USB ports may have bogus location data in ACPI PLD tables. This causes port peering failures as these unused USB2 and USB3 ports location may match. Due to these failures the driver prints a "usb: port power management may be unreliable" warning, and unnecessarily blocks port power off during runtime suspend. This was debugged on a couple DELL systems where the unused ports all returned zeroes in their location data. Similar bugreports exist for other systems. Don't try to peer or match ports that have connect type set to USB_PORT_NOT_USED.

[PATCH] etnaviv: Restore some id values

by Christian Gmeiner

From: Christian Gmeiner <cgmeiner(a)igalia.com> The hwdb selection logic as a feature that allows it to mark some fields as 'don't care'. If we match with such a field we memcpy(..) the current etnaviv_chip_identity into ident. This step can overwrite some id values read from the GPU with the 'don't care' value. Fix this issue by restoring the affected values after the memcpy(..). As this is crucial for user space to know when this feature works as expected increment the minor version too.
