2025-03-22HID: apple: disable Fn key handling on the Omoton KB066Alex Henrie1-4/+7
commit 221cea1003d8a412e5ec64a58df7ab19b654f490 upstream. Remove the fixup to make the Omoton KB066's F6 key F6 when not holding Fn. That was really just a hack to allow typing F6 in fnmode>0, and it didn't fix any of the other F keys that were likewise untypable in fnmode>0. Instead, because the Omoton's Fn key is entirely internal to the keyboard, completely disable Fn key translation when an Omoton is detected, which will prevent the hid-apple driver from interfering with the keyboard's built-in Fn key handling. All of the F keys, including F6, are then typable when Fn is held. The Omoton KB066 and the Apple A1255 both have HID product code 05ac:022c. The self-reported name of every original A1255 when they left the factory was "Apple Wireless Keyboard". By default, Mac OS changes the name to "<username>'s keyboard" when pairing with the keyboard, but Mac OS allows the user to set the internal name of Apple keyboards to anything they like. The Omoton KB066's name, on the other hand, is not configurable: It is always "Bluetooth Keyboard". Because that name is so generic that a user might conceivably use the same name for a real Apple keyboard, detect Omoton keyboards based on both having that exact name and having HID product code 022c.

2025-03-22nvme-fc: rely on state transitions to handle connectivity lossDaniel Wagner1-61/+6
commit f13409bb3f9140dad7256febcb478f0c9600312c upstream. It's not possible to call nvme_state_ctrl_state with holding a spin lock, because nvme_state_ctrl_state calls cancel_delayed_work_sync when fastfail is enabled. Instead syncing the ASSOC_FLAG and state transitions using a lock, it's possible to only rely on the state machine transitions. That means nvme_fc_ctrl_connectivity_loss should unconditionally call nvme_reset_ctrl which avoids the read race on the ctrl state variable. Actually, it's not necessary to test in which state the ctrl is, the reset work will only scheduled when the state machine is in LIVE state. In nvme_fc_create_association, the LIVE state can only be entered if it was previously CONNECTING. If this is not possible then the reset handler got triggered. Thus just error out here.

[ Upstream commit eea5119fa5979c350af5783a8148eacdd4219715 ] There are now more servers which advertise support for IAKerb (passthrough Kerberos authentication via proxy). IAKerb is a public extension industry standard Kerberos protocol that allows a client without line-of-sight to a Domain Controller to authenticate. There can be cases where we would fail to mount if the server only advertises the OID for IAKerb in SPNEGO/GSSAPI. Add code to allow us to still upcall to userspace in these cases to obtain the Kerberos ticket.

2025-03-22mm/hugetlb: wait for hugetlb folios to be freedGe Yang3-0/+23
[ Upstream commit 67bab13307c83fb742c2556b06cdc39dbad27f07 ] Since the introduction of commit c77c0a8ac4c52 ("mm/hugetlb: defer freeing of huge pages if in non-task context"), which supports deferring the freeing of hugetlb pages, the allocation of contiguous memory through cma_alloc() may fail probabilistically. In the CMA allocation process, if it is found that the CMA area is occupied by in-use hugetlb folios, these in-use hugetlb folios need to be migrated to another location. When there are no available hugetlb folios in the free hugetlb pool during the migration of in-use hugetlb folios, new folios are allocated from the buddy system. A temporary state is set on the newly allocated folio. Upon completion of the hugetlb folio migration, the temporary state is transferred from the new folios to the old folios. Normally, when the old folios with the temporary state are freed, it is directly released back to the buddy system. However, due to the deferred freeing of hugetlb pages, the PageBuddy() check fails, ultimately leading to the failure of cma_alloc(). Here is a simplified call trace illustrating the process: cma_alloc() ->__alloc_contig_migrate_range() // Migrate in-use hugetlb folios ->unmap_and_move_huge_page() ->folio_putback_hugetlb() // Free old folios ->test_pages_isolated() ->__test_page_isolated_in_pageblock() ->PageBuddy(page) // Check if the page is in buddy To resolve this issue, we have implemented a function named wait_for_freed_hugetlb_folios(). This function ensures that the hugetlb folios are properly released back to the buddy system after their migration is completed. By invoking wait_for_freed_hugetlb_folios() before calling PageBuddy(), we ensure that PageBuddy() will succeed.

2025-03-22block: change blk_mq_add_to_batch() third argument type to boolShin'ichiro Kawasaki5-11/+22
[ Upstream commit 9bce6b5f8987678b9c6c1fe433af6b5fe41feadc ] Commit 1f47ed294a2b ("block: cleanup and fix batch completion adding conditions") modified the evaluation criteria for the third argument, 'ioerror', in the blk_mq_add_to_batch() function. Initially, the function had checked if 'ioerror' equals zero. Following the commit, it started checking for negative error values, with the presumption that such values, for instance -EIO, would be passed in. However, blk_mq_add_to_batch() callers do not pass negative error values. Instead, they pass status codes defined in various ways: - NVMe PCI and Apple drivers pass NVMe status code - virtio_blk driver passes the virtblk request header status byte - null_blk driver passes blk_status_t These codes are either zero or positive, therefore the revised check fails to function as intended. Specifically, with the NVMe PCI driver, this modification led to the failure of the blktests test case nvme/039. In this test scenario, errors are artificially injected to the NVMe driver, resulting in positive NVMe status codes passed to blk_mq_add_to_batch(), which unexpectedly processes the failed I/O in a batch. Hence the failure. To correct the ioerror check within blk_mq_add_to_batch(), make all callers to uniformly pass the argument as boolean. Modify the callers to check their specific status codes and pass the boolean value 'is_error'. Also describe the arguments of blK_mq_add_to_batch as kerneldoc.

This was insufficient because both bits of configuration are required for each crate; the result is that rust-analyzer is unable to resolve generated files for either crate in an out-of-source build. [ Originally we were not using `OBJTREE` in the `kernel` crate, but we did pass the variable anyway, so conceptually it could have been there since then. Regarding `include_dirs`, it started in `kernel` before being in mainline because we included the bindings directly there (i.e. there was no `bindings` crate). However, when that crate got created, we moved the `OBJTREE` there but not the `include_dirs`. Nowadays, though, we happen to need the `include_dirs` also in the `kernel` crate for `generated_arch_static_branch_asm.rs` which was not there back then -- Tamir confirms it is indeed required for that reason. - Miguel ] Add the missing bits to improve the developer experience.

After the commit, blk_mq_add_to_batch() always adds passthrough requests to batch regardless of whether the request failed or not, and returns true. This affected error logging feature in the NVME driver. Before the commit, the call chain of failed passthrough request was as follows: nvme_handle_cqe() blk_mq_add_to_batch() .. false is returned, then call nvme_pci_complete_rq() nvme_pci_complete_rq() nvme_complete_rq() nvme_end_req() nvme_log_err_passthru() .. error logging __nvme_end_req() .. end of the rqeuest After the commit, the call chain is as follows: nvme_handle_cqe() blk_mq_add_to_batch() .. true is returned, then set nvme_pci_complete_batch() .. nvme_pci_complete_batch() nvme_complete_batch() nvme_complete_batch_req() __nvme_end_req() .. end of the request, without error logging To make the error logging feature work again for passthrough requests, move the nvme_log_err_passthru() call from nvme_end_req() to __nvme_end_req(). While at it, move nvme_log_error() call for non-passthrough requests together with nvme_log_err_passthru().

2025-03-22drm/xe/pm: Temporarily disable D3Cold on BMGRodrigo Vivi1-1/+12
[ Upstream commit 3e331a6715ee26f2fabc59dad6bb36d810707028 ] Currently, many instability cases related to D3Cold -> D0 transition on BMG are under investigation. Among them some bad cases where the device is lost after 1 to 3 transitions from D3Cold to D0 on the runtime pm, with pcieport upstream bridge port link retrain failure. In other cases, it works fine, but with some sudden random memory corruptions after D3cold, that could be 0xffff missed ack on GT forcewake or GuC reload related failures. In some other cases though, D3Cold -> D0 works pretty reliably. It looks like it is a combination of GPU cards and Host boards at this point. So, there is no possible/available quirk at this time. This patch disables the D3Cold by default on BMG by reducing the vram_d3cold_threshold to 0.

There are two ways the platform_max could be interpreted; the maximum register value, or the maximum value the control can be set to. The patch moved from treating the value as a control value to a register one. When the patch was applied it was technically correct as snd_soc_limit_volume() also used the register interpretation. However, even then most of the other usages treated platform_max as a control value, and snd_soc_limit_volume() has since been updated to also do so in commit fb9ad24485087 ("ASoC: ops: add correct range check for limiting volume"). That patch however, missed updating snd_soc_put_volsw() back to the control interpretation, and fixing snd_soc_info_volsw_range(). The control interpretation makes more sense as limiting is typically done from the machine driver, so it is appropriate to use the customer facing representation rather than the internal codec representation. Update all the code to consistently use this interpretation of platform_max. Finally, also add some comments to the soc_mixer_control struct to hopefully avoid further patches switching between the two approaches.

TJA1120B/TJA1121B can achieve a stable operation of SGMII after a startup event by putting the SGMII PCS into power down mode and restart afterwards. It is necessary to put the SGMII PCS into power down mode and back up.

commit a07364b394697d2e0baffeb517f41385259aa484 upstream. The most recent sillicon versions of TJA1120 and TJA1121 can achieve full silicon performance by putting the PHY in managed mode. It is necessary to apply these PHY writes before link gets established. Application of this fix is required after restart of device and wakeup from sleep.

commit fc99045effa81fdf509c2a97cbb7e6e8f2fd4443 upstream. When mounting a CIFS share with 'guest' mount option, mount.cifs(8) will set empty password= and password2= options. Currently we only handle empty strings from user= and password= options, so the mount will fail with cifs: Bad value for 'password2' Fix this by handling empty string from password2= option as well.

2025-03-22Fix mmu notifiers for range-based invalidatesPiotr Jaroszynski1-10/+12
commit f7edb07ad7c66eab3dce57384f33b9799d579133 upstream. Update the __flush_tlb_range_op macro not to modify its parameters as these are unexepcted semantics. In practice, this fixes the call to mmu_notifier_arch_invalidate_secondary_tlbs() in __flush_tlb_range_nosync() to use the correct range instead of an empty range with start=end. The empty range was (un)lucky as it results in taking the invalidate-all path that doesn't cause correctness issues, but can certainly result in suboptimal perf. This has been broken since commit 6bbd42e2df8f ("mmu_notifiers: call invalidate_range() when invalidating TLBs") when the call to the notifiers was added to __flush_tlb_range(). It predates the addition of the __flush_tlb_range_op() macro from commit 360839027a6e ("arm64: tlb: Refactor the core flush algorithm of __flush_tlb_range") that made the bug hard to spot.

2025-03-22arm64: mm: Populate vmemmap at the page level if not section alignedZhenhua Huang1-1/+4
commit d4234d131b0a3f9e65973f1cdc71bb3560f5d14b upstream. On the arm64 platform with 4K base page config, SECTION_SIZE_BITS is set to 27, making one section 128M. The related page struct which vmemmap points to is 2M then. Commit c1cc1552616d ("arm64: MMU initialisation") optimizes the vmemmap to populate at the PMD section level which was suitable initially since hot plug granule is always one section(128M). However, commit ba72b4c8cf60 ("mm/sparsemem: support sub-section hotplug") introduced a 2M(SUBSECTION_SIZE) hot plug granule, which disrupted the existing arm64 assumptions. The first problem is that if start or end is not aligned to a section boundary, such as when a subsection is hot added, populating the entire section is wasteful. The next problem is if we hotplug something that spans part of 128 MiB section (subsections, let's call it memblock1), and then hotplug something that spans another part of a 128 MiB section(subsections, let's call it memblock2), and subsequently unplug memblock1, vmemmap_free() will clear the entire PMD entry which also supports memblock2 even though memblock2 is still active. Assuming hotplug/unplug sizes are guaranteed to be symmetric. Do the fix similar to x86-64: populate to pages levels if start/end is not aligned with section boundary.

2025-03-22netmem: prevent TX of unreadable skbsMina Almasry1-0/+3
commit f3600c867c99a2cc8038680ecf211089c50e7971 upstream. Currently on stable trees we have support for netmem/devmem RX but not TX. It is not safe to forward/redirect an RX unreadable netmem packet into the device's TX path, as the device may call dma-mapping APIs on dma addrs that should not be passed to it. Fix this by preventing the xmit of unreadable skbs. Tested by configuring tc redirect: sudo tc qdisc add dev eth1 ingress sudo tc filter add dev eth1 ingress protocol ip prio 1 flower ip_proto \ tcp src_ip 192.168.1.12 action mirred egress redirect dev eth1 Before, I see unreadable skbs in the driver's TX path passed to dma mapping APIs. After, I don't see unreadable skbs in the driver's TX path passed to dma mapping APIs.
