11 daysACPICA: Provide #defines for EINJV2 error typesTony Luck
EINJV2 defined new error types by moving the severity (correctable, uncorrectable non-fatal, uncorrectable fatal) out of the "type". ACPI 6.5 introduced EINJV2 and defined a vendor defined error type using bit 31. This was dropped in ACPI 6.6.

12 daysmtd: spinand: Add support for packed read data ODTR commandsMiquel Raynal
Some devices stuff address bits in the double byte opcode (in place of the repeated byte) in order to be able to increase the size of the devices, without adding extra address bytes. Create a flag to identify those devices. When the flag is set, use the "packed" variant for the read data operation. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

12 daysmm/vma: do not try to unmap a VMA if mmap_prepare() invoked from mmap()Lorenzo Stoakes
The mmap_prepare hook functionality includes the ability to invoke mmap_prepare() from the mmap() hook of existing 'stacked' drivers, that is ones which are capable of calling the mmap hooks of other drivers/file systems (e.g. overlayfs, shm). As part of the mmap_prepare action functionality, we deal with errors by unmapping the VMA should one arise. This works in the usual mmap_prepare case, as we invoke this action at the last moment, when the VMA is established in the maple tree. However, the mmap() hook passes a not-fully-established VMA pointer to the caller (which is the motivation behind the mmap_prepare() work), which is detached. So attempting to unmap a VMA in this state will be problematic, with the most obvious symptom being a warning in vma_mark_detached(), because the VMA is already detached. It's also unncessary - the mmap() handler will clean up the VMA on error. So to fix this issue, this patch propagates whether or not an mmap action is being completed via the compatibility layer or directly. If the former, then we do not attempt VMA cleanup, if the latter, then we do. This patch also updates the userland VMA tests to reflect the change.

We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code.

2026-04-24eventpoll: refresh eventpoll_release() fast-path commentChristian Brauner
The old comment justified the lockless READ_ONCE(file->f_ep) check with "False positives simply cannot happen because the file is on the way to be removed and nobody ( but eventpoll ) has still a reference to this file." That reasoning was the root of the UAF fixed in "eventpoll: fix ep_remove struct eventpoll / struct file UAF": __ep_remove() could clear f_ep while another close raced past the fast path and freed the watched eventpoll / recycled the struct file slot. With ep_remove() now pinning @file via epi_fget() across the f_ep clear and hlist_del_rcu(), the invariant is re-established for the right reason: anyone who might clear f_ep holds @file alive for the duration, so a NULL observation really does mean no concurrent eventpoll path has work left on this file. Refresh the comment accordingly so the next reader doesn't inherit the broken model.

2026-04-23rxrpc: Fix re-decryption of RESPONSE packetsDavid Howells
If a RESPONSE packet gets a temporary failure during processing, it may end up in a partially decrypted state - and then get requeued for a retry. Fix this by just discarding the packet; we will send another CHALLENGE packet and thereby elicit a further response. Similarly, discard an incoming CHALLENGE packet if we get an error whilst generating a RESPONSE; the server will send another CHALLENGE.

2026-04-23rxrpc: Fix potential UAF after skb_unshare() failureDavid Howells
If skb_unshare() fails to unshare a packet due to allocation failure in rxrpc_input_packet(), the skb pointer in the parent (rxrpc_io_thread()) will be NULL'd out. This will likely cause the call to trace_rxrpc_rx_done() to oops. Fix this by moving the unsharing down to where rxrpc_input_call_event() calls rxrpc_input_call_packet(). There are a number of places prior to that where we ignore DATA packets for a variety of reasons (such as the call already being complete) for which an unshare is then avoided. And with that, rxrpc_input_packet() doesn't need to take a pointer to the pointer to the packet, so change that to just a pointer.

2026-04-22nvme-auth: Hash DH shared secret to create session keyChris Leech
The NVMe Base Specification 8.3.5.5.9 states that the session key Ks shall be computed from the ephemeral DH key by applying the hash function selected by the HashID parameter. The current implementation stores the raw DH shared secret as the session key without hashing it. This causes redundant hash operations: 1. Augmented challenge computation (section 8.3.5.5.4) requires Ca = HMAC(H(g^xy mod p), C). The code compensates by hashing the unhashed session key in nvme_auth_augmented_challenge() to produce the correct result. 2. PSK generation (section 8.3.5.5.9) requires PSK = HMAC(Ks, C1 || C2) where Ks should already be H(g^xy mod p). As the DH shared secret is always larger than the HMAC block size, HMAC internally hashes it before use, accidentally producing the correct result. When using secure channel concatenation with bidirectional authentication, this results in hashing the DH value three times: twice for augmented challenge calculations and once during PSK generation. Fix this by: - Modifying nvme_auth_gen_shared_secret() to hash the DH shared secret once after computation: Ks = H(g^xy mod p) - Removing the hash operation from nvme_auth_augmented_challenge() as the session key is now already hashed - Updating session key buffer size from DH key size to hash output size - Adding specification references in comments This avoid storing the raw DH shared secret and reduces the number of hash operations from three to one when using secure channel concatenation.

2026-04-22NFS: fix writeback in presence of errorsOlga Kornievskaia
After running xfstest generic/751, in certain conditions, can have a writeback IO stuck while experiencing one of the two patterns. Pattern#1: writeback IO experiences ENOSPC on an offset smaller than the filesize. Example, write offset=0 len=4096 how=unstable OK write offset=8192 len=4096 how=unstable OK write offset=12288 len=4096 how=unstable ENOSPC write offset=4096 len=4096 how=unstable ENOSPC client sends a commit and receives a verifier which is different from the last successful write. It marks pages dirty and writeback retries. But it again send writes unstable and gets into the same pattern, running into the ENOSPC error and sending a commit because writes were sent at unstable. Pattern#2: an unstable write followed by a short write and ENOSPC. write offset=0 len=4096 how=unstable OK write offset=4096 len=4096 how=unstable returns OK but count=100 write offset=4197 len=3996 how=stable returns ENOSPC client send a commit and receives a verifier different from the last unstable write. The same behaviour is retried in a loop. Instead, this patch proposes to identify those conditions and mark requests to be done synchronously instead. Previous solution tried to mark it in the nfs_page, however that's not persistent thus instead mark it in the nfs_open_context. Furthermore, the same problem occurs during localio code path so recognize that IO needs to be done sync in that case as well.

2026-04-22x86/hyperv: Skip LP/VP creation on kexecJork Loeser
After a kexec the logical processors and virtual processors already exist in the hypervisor because they were created by the previous kernel. Attempting to add them again causes either a BUG_ON or corrupted VP state leading to MCEs in the new kernel. Add hv_lp_exists() to probe whether an LP is already present by calling HVCALL_GET_LOGICAL_PROCESSOR_RUN_TIME. When it succeeds the LP exists and we skip the add-LP and create-VP loops entirely. Also add hv_call_notify_all_processors_started() which informs the hypervisor that all processors are online. This is required after adding LPs (fresh boot) and is a no-op on kexec since we skip that path.

However, in HS LSS mode with resetmode = HS_MODE, if the UFS device's default bRefClkFreq value differs from the host controller's dev_ref_clk_freq setting, the write operation will fail. To fix this issue, introduce ufshcd_get_op_mode() function to detect the current link operational mode.
