2025-03-07virt: sev-guest: Move SNP Guest Request data pages handling under snp_cmd_mutexAlexey Kardashevskiy
Compared to the SNP Guest Request, the "Extended" version adds data pages for receiving certificates. If not enough pages provided, the HV can report to the VM how much is needed so the VM can reallocate and repeat. Commit ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex") moved handling of the allocated/desired pages number out of scope of said mutex and create a possibility for a race (multiple instances trying to trigger Extended request in a VM) as there is just one instance of snp_msg_desc per /dev/sev-guest and no locking other than snp_cmd_mutex. Fix the issue by moving the data blob/size and the GHCB input struct (snp_req_data) into snp_guest_req which is allocated on stack now and accessed by the GHCB caller under that mutex. Stop allocating SEV_FW_BLOB_MAX_SIZE in snp_msg_alloc() as only one of four callers needs it. Free the received blob in get_ext_report() right after it is copied to the userspace. Possible future users of snp_send_guest_request() are likely to have different ideas about the buffer size anyways.

2025-03-07virt: sev-guest: Allocate request data dynamicallyNikunj A Dadhania
Commit ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex") narrowed the command mutex scope to snp_send_guest_request(). However, GET_REPORT, GET_DERIVED_KEY, and GET_EXT_REPORT share the req structure in snp_guest_dev. Without the mutex protection, concurrent requests can overwrite each other's data. Fix it by dynamically allocating the request structure.

2025-03-06fs/pipe: add simpler helpers for common casesLinus Torvalds
The fix to atomically read the pipe head and tail state when not holding the pipe mutex has caused a number of headaches due to the size change of the involved types. It turns out that we don't have _that_ many places that access these fields directly and were affected, but we have more than we strictly should have, because our low-level helper functions have been designed to have intimate knowledge of how the pipes work. And as a result, that random noise of direct 'pipe->head' and 'pipe->tail' accesses makes it harder to pinpoint any actual potential problem spots remaining. For example, we didn't have a "is the pipe full" helper function, but instead had a "given these pipe buffer indexes and this pipe size, is the pipe full". That's because some low-level pipe code does actually want that much more complicated interface. But most other places literally just want a "is the pipe full" helper, and not having it meant that those places ended up being unnecessarily much too aware of this all. It would have been much better if only the very core pipe code that cared had been the one aware of this all. So let's fix it - better late than never. This just introduces the trivial wrappers for "is this pipe full or empty" and to get how many pipe buffers are used, so that instead of writing if (pipe_full(pipe->head, pipe->tail, pipe->max_usage)) the places that literally just want to know if a pipe is full can just say if (pipe_is_full(pipe)) instead. The existing trivial cases were converted with a 'sed' script. This cuts down on the places that access pipe->head and pipe->tail directly outside of the pipe code (and core splice code) quite a lot. The splice code in particular still revels in doing the direct low-level accesses, and the fuse fuse_dev_splice_write() code also seems a bit unnecessarily eager to go very low-level, but it's at least a bit better than it used to be.

2025-03-05drm/xe/userptr: Unmap userptrs in the mmu notifierThomas Hellström
If userptr pages are freed after a call to the xe mmu notifier, the device will not be blocked out from theoretically accessing these pages unless they are also unmapped from the iommu, and this violates some aspects of the iommu-imposed security. Ensure that userptrs are unmapped in the mmu notifier to mitigate this. A naive attempt would try to free the sg table, but the sg table itself may be accessed by a concurrent bind operation, so settle for only unmapping. v3: - Update lockdep asserts. - Fix a typo (Matthew Auld) Fixes: 81e058a3e7fd ("drm/xe: Introduce helper to populate userptr") Cc: Oak Zeng <oak.zeng@intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Cc: <stable@vger.kernel.org> # v6.10+ Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Acked-by: Matthew Brost <matthew.brost@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250304173342.22009-4-thomas.hellstrom@linux.intel.com (cherry picked from commit ba767b9d01a2c552d76cf6f46b125d50ec4147a6) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2025-03-05drm/xe/hmm: Don't dereference struct page pointers without notifier lockThomas Hellström
The pnfs that we obtain from hmm_range_fault() point to pages that we don't have a reference on, and the guarantee that they are still in the cpu page-tables is that the notifier lock must be held and the notifier seqno is still valid. So while building the sg table and marking the pages accesses / dirty we need to hold this lock with a validated seqno. However, the lock is reclaim tainted which makes sg_alloc_table_from_pages_segment() unusable, since it internally allocates memory. Instead build the sg-table manually. For the non-iommu case this might lead to fewer coalesces, but if that's a problem it can be fixed up later in the resource cursor code. For the iommu case, the whole sg-table may still be coalesced to a single contigous device va region. This avoids marking pages that we don't own dirty and accessed, and it also avoid dereferencing struct pages that we don't own. v2: - Use assert to check whether hmm pfns are valid (Matthew Auld) - Take into account that large pages may cross range boundaries (Matthew Auld) v3: - Don't unnecessarily check for a non-freed sg-table. (Matthew Auld) - Add a missing up_read() in an error path.

2025-03-05drm/xe: Add staging tree for VM bindsMatthew Brost
Concurrent VM bind staging and zapping of PTEs from a userptr notifier do not work because the view of PTEs is not stable. VM binds cannot acquire the notifier lock during staging, as memory allocations are required. To resolve this race condition, use a staging tree for VM binds that is committed only under the userptr notifier lock during the final step of the bind. This ensures a consistent view of the PTEs in the userptr notifier. A follow up may only use staging for VM in fault mode as this is the only mode in which the above race exists. v3: - Drop zap PTE change (Thomas) - s/xe_pt_entry/xe_pt_entry_staging (Thomas) Suggested-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: <stable@vger.kernel.org> Fixes: e8babb280b5e ("drm/xe: Convert multiple bind ops into single job") Fixes: a708f6501c69 ("drm/xe: Update PT layer with better error handling") Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250228073058.59510-5-thomas.hellstrom@linux.intel.com Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> (cherry picked from commit 6f39b0c5ef0385eae586760d10b9767168037aa5) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2025-03-05drm/xe: Fix fault mode invalidation with unbindThomas Hellström
Fix fault mode invalidation racing with unbind leading to the PTE zapping potentially traversing an invalid page-table tree. Do this by holding the notifier lock across PTE zapping. This might transfer any contention waiting on the notifier seqlock read side to the notifier lock read side, but that shouldn't be a major problem. At the same time get rid of the open-coded invalidation in the bind code by relying on the notifier even when the vma bind is not yet committed. Finally let userptr invalidation call a dedicated xe_vm function performing a full invalidation.

2025-03-05ublk: set_params: properly check if parameters can be appliedUday Shankar
The parameters set by the set_params call are only applied to the block device in the start_dev call. So if a device has already been started, a subsequently issued set_params on that device will not have the desired effect, and should return an error. There is an existing check for this - set_params fails on devices in the LIVE state. But this check is not sufficient to cover the recovery case. In this case, the device will be in the QUIESCED or FAIL_IO states, so set_params will succeed. But this success is misleading, because the parameters will not be applied, since the device has already been started (by a previous ublk server). The bit UB_STATE_USED is set on completion of the start_dev; use it to detect and fail set_params commands which arrive too late to be applied (after start_dev).

2025-03-05gpio: aggregator: protect driver attr handlers against module unloadKoichiro Den
Both new_device_store and delete_device_store touch module global resources (e.g. gpio_aggregator_lock). To prevent race conditions with module unload, a reference needs to be held. Add try_module_get() in these handlers. For new_device_store, this eliminates what appears to be the most dangerous scenario: if an id is allocated from gpio_aggregator_idr but platform_device_register has not yet been called or completed, a concurrent module unload could fail to unregister/delete the device, leaving behind a dangling platform device/GPIO forwarder. This can result in various issues. The following simple reproducer demonstrates these problems: #!/bin/bash while :; do # note: whether 'gpiochip0 0' exists or not does not matter. echo 'gpiochip0 0' > /sys/bus/platform/drivers/gpio-aggregator/new_device done & while :; do modprobe gpio-aggregator modprobe -r gpio-aggregator done & wait Starting with the following warning, several kinds of warnings will appear and the system may become unstable: ------------[ cut here ]------------ list_del corruption, ffff888103e2e980->next is LIST_POISON1 (dead000000000100) WARNING: CPU: 1 PID: 1327 at lib/list_debug.c:56 __list_del_entry_valid_or_report+0xa3/0x120 [...] RIP: 0010:__list_del_entry_valid_or_report+0xa3/0x120 [...] Call Trace: <TASK> ? __list_del_entry_valid_or_report+0xa3/0x120 ? __warn.cold+0x93/0xf2 ? __list_del_entry_valid_or_report+0xa3/0x120 ? report_bug+0xe6/0x170 ? __irq_work_queue_local+0x39/0xe0 ? handle_bug+0x58/0x90 ? exc_invalid_op+0x13/0x60 ? asm_exc_invalid_op+0x16/0x20 ? __list_del_entry_valid_or_report+0xa3/0x120 gpiod_remove_lookup_table+0x22/0x60 new_device_store+0x315/0x350 [gpio_aggregator] kernfs_fop_write_iter+0x137/0x1f0 vfs_write+0x262/0x430 ksys_write+0x60/0xd0 do_syscall_64+0x6c/0x180 entry_SYSCALL_64_after_hwframe+0x76/0x7e [...] </TASK> ---[ end trace 0000000000000000 ]--- Fixes: 828546e24280 ("gpio: Add GPIO Aggregator") Cc: stable@vger.kernel.org Signed-off-by: Koichiro Den <koichiro.den@canonical.com> Link: https://lore.kernel.org/r/20250224143134.3024598-2-koichiro.den@canonical.com Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
2025-03-05platform/x86/amd/pmf: Update PMF Driver for Compatibility with new PMF-TAShyam Sundar S K
The PMF driver allocates a shared memory buffer using tee_shm_alloc_kernel_buf() for communication with the PMF-TA. The latest PMF-TA version introduces new structures with OEM debug information and additional policy input conditions for evaluating the policy binary. Consequently, the shared memory size must be increased to ensure compatibility between the PMF driver and the updated PMF-TA. To do so, introduce the new PMF-TA UUID and update the PMF shared memory configuration to ensure compatibility with the latest PMF-TA version. Additionally, export the TA UUID. These updates will result in modifications to the prototypes of amd_pmf_tee_init() and amd_pmf_ta_open_session().

2025-03-04ppp: Fix KMSAN uninit-value warning with bpfJiayuan Chen
Syzbot caught an "KMSAN: uninit-value" warning [1], which is caused by the ppp driver not initializing a 2-byte header when using socket filter. The following code can generate a PPP filter BPF program: ''' struct bpf_program fp; pcap_t *handle; handle = pcap_open_dead(DLT_PPP_PPPD, 65535); pcap_compile(handle, &fp, "ip and outbound", 0, 0); bpf_dump(&fp, 1); ''' Its output is: ''' (000) ldh [2] (001) jeq #0x21 jt 2 jf 5 (002) ldb [0] (003) jeq #0x1 jt 4 jf 5 (004) ret #65535 (005) ret #0 ''' Wen can find similar code at the following link: https://github.com/ppp-project/ppp/blob/master/pppd/options.c#L1680 The maintainer of this code repository is also the original maintainer of the ppp driver. As you can see the BPF program skips 2 bytes of data and then reads the 'Protocol' field to determine if it's an IP packet. Then it read the first byte of the first 2 bytes to determine the direction. The issue is that only the first byte indicating direction is initialized in current ppp driver code while the second byte is not initialized. For normal BPF programs generated by libpcap, uninitialized data won't be used, so it's not a problem. However, for carefully crafted BPF programs, such as those generated by syzkaller [2], which start reading from offset 0, the uninitialized data will be used and caught by KMSAN.
