2026-07-20entry: Rework syscall_audit_enter()Thomas Gleixner2-11/+15
Move it out of line and let it reread the syscall number on it's own. That makes the low level entry code denser and allows to move the reread to the call site of syscall_trace_enter() once the tracer is fixed up. To prevent the compiler from putting audit_context() out of line and thereby breaking dead code elimination, mark audit_context() __always_inline.

2026-07-20fscrypt: Always use blk-crypto for contents on block-based filesystemsEric Biggers9-140/+57
For encrypting and decrypting file contents on block-based filesystems (i.e., ext4 and f2fs, but not ceph and ubifs), always use blk-crypto instead of fs-layer crypto (direct use of crypto_skcipher). Since the blk-crypto API provides a fallback to CPU-based encryption, it's all that's needed on block-based filesystems. The support for two alternative block-based file contents encryption implementations, fs-layer and blk-crypto, existed mainly for historical reasons, as the fs-layer path came first. Some of it is also still needed for the non-block-based filesystems, but a lot of it isn't. Removing the duplicate fs-layer code paths greatly simplifies the code, most of which is done in later commits. Specific implementation details: - SB_INLINECRYPT now controls whether blk_crypto_config::allow_hw is set to true, instead of whether blk-crypto is used at all. The effect is that the semantics are preserved: the inlinecrypt mount option selects the use of inline encryption hardware instead of the CPU. - Set up a blk_crypto_key iff the file is a regular file on a block-based filesystem. To determine whether the filesystem is block-based, add a bit fscrypt_operations::is_block_based. - Remove fscrypt_select_encryption_impl(). Move the logging logic that was previously there into fscrypt_prepare_inline_crypt_key(). Note that blk_crypto_config_supported() is no longer needed.

FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32 with s_blocksize != PAGE_SIZE works only with the fs-layer implementation of file contents encryption, not blk-crypto. This is a problem for standardizing on blk-crypto. Fortunately, no one should be using this combination anyway. It doesn't make sense because the entire point of IV_INO_LBLK_32 is to support inline encryption hardware that is limited to 32-bit DUNs. Thus, fully disallow IV_INO_LBLK_32 with s_blocksize != PAGE_SIZE.

2026-07-20blk-crypto: Allow control over whether hardware is usedEric Biggers4-4/+27
fscrypt uses inline encryption hardware only when the "inlinecrypt" mount option is given. I'd like to keep that behavior even after standardizing on the blk-crypto API for file contents encryption. That is, the default should continue to be the well-tested CPU-based encryption code, and the use of inline encryption hardware should continue to be an opt-in feature for systems where it's beneficial and has been fully validated (including verifying ciphertext correctness). To support this use case, extend blk_crypto_config with a new flag BLK_CRYPTO_CFG_ALLOW_HW. For now it's always set. Later commits will change that.

2026-07-20fscrypt: Simplify handling of errors during initcallEric Biggers3-34/+13
Since CONFIG_FS_ENCRYPTION is a bool, not a tristate, fs/crypto/ can only be builtin or absent entirely; it can't be a loadable module. Therefore, the error code that gets returned from the fscrypt_init() initcall is never used. If any part of the initcall does fail, which should never happen, the kernel will be left in a bad state. Following the usual convention for builtin code, just panic the kernel if any of part of the initcall fails. This simplifies the code. This closely mirrors commit e77000ccc531 ("fsverity: simplify handling of errors during initcall").

2026-07-20fscrypt: Avoid dynamic allocation in fscrypt_get_devices()Eric Biggers3-56/+44
When a blk_crypto_key starts being used or is evicted, fs/crypto/ calls fscrypt_get_devices() to get the filesystem's list of block devices, then iterates over them and calls blk_crypto_config_supported(), blk_crypto_start_using_key(), or blk_crypto_evict_key() on each one. Currently, the block device pointers are placed in a dynamically allocated array. This dynamic allocation is problematic because: - It can fail, especially at the fscrypt_destroy_inline_crypt_key() call site when it's invoked for inode eviction under direct reclaim. - fscrypt_destroy_inline_crypt_key() doesn't handle the failure. It just zeroizes and frees the blk_crypto_key without calling blk_crypto_evict_key(). That causes a use-after-free. For now, let's fix this in the straightforward and easily-backportable way by switching to an on-stack array. Currently the fscrypt multi-device functionality is used only by f2fs, which has a hardcoded limit of 8 block devices. An on-stack array works fine for that. (Of course, this solution won't scale up to large number of block devices. For that we'd need a different solution, like moving the block device iteration into the filesystem. Or in the case of btrfs, which will only support blk-crypto-fallback, we should make it just call blk-crypto-fallback directly, so the block devices won't be needed.)

2026-07-20fscrypt: Add missing superblock check in find_or_insert_direct_key()Eric Biggers1-1/+7
The legacy 'fscrypt_direct_keys' table caches master keys that are used by v1 encryption policies that have FSCRYPT_POLICY_FLAG_DIRECT_KEY. It's just a global table for all filesystems (since the keys can be provided by the legacy process-subscribed keyrings mechanism, which makes it difficult to reuse super_block::s_master_keys). The entries in it ('struct fscrypt_direct_key') do contain a super_block pointer, though, for passing to fscrypt_destroy_inline_crypt_key() when the last inode that references the key is evicted. However, when finding the fscrypt_direct_key for an inode, we weren't actually comparing the super_block pointer. As a result, inodes with different super_blocks could point to the same fscrypt_direct_key. That could extend the lifetime of a fscrypt_direct_key beyond the super_block it points to, causing a use-after-free later. Fix this by creating distinct fscrypt_direct_key structs for distinct super_block structs. Note that this problem doesn't exist in the v2 policy equivalent ("per-mode keys"), since the data structures there are per super_block.

Add a remoteproc driver for AMD MicroBlaze/V soft-core processor subsystems instantiated in programmable logic and using dual-port BRAM for firmware storage and execution. The driver parses the firmware memory window from the remoteproc device node's reg property, interprets that address and size in the processor-local address space, and then uses standard devicetree address translation through the parent bus ranges property to obtain the corresponding Linux-visible system physical address. The resulting translated region is registered as the executable remoteproc carveout and coredump segment. The processor is controlled through an active-low reset GPIO and a subsystem clock. The clock is enabled before reset is released, and the processor is kept in reset until firmware loading completes. The firmware-name property is optional, allowing firmware to be assigned later through the remoteproc framework. Firmware images without a resource table are also accepted.

2026-07-20x86/bugs: Don't use cpu-type matching in cpu_vuln_blacklistPawan Gupta1-8/+17
Thomas Gleixner pointed out that cpu-type is a per-CPU property while hybrid is a system property; conflating the two in the CPU matching infrastructure is wrong. Currently, on a hybrid system x86_match_cpu() matches any cpu-type. This works if the intent is to find the possibility of a cpu-type in a system. But fails if matching for the cpu-type of a given CPU. Borislav posted a cleanup here: https://lore.kernel.org/all/20260703193222.GFakgORjvxwnZTPRnI@fat_crate.local To make way for the cleanup stop matching cpu-type in cpu_vuln_blacklist. RFDS is the only user, so drop the VULNBL_INTEL_TYPE entries and fold their RFDS bit into the base Alder Lake (0x97) and Raptor Lake (0xB7) blacklist entries. For now open-code cpu-type check in vulnerable_to_rfds(). In the future, if more vulnerabilities need cpu-type matching a helper can be added. No functional change intended.

2026-07-20arm64: dts: imx8-ss-audio: Fix LPCG clock indices for ASRC0Frank Li1-4/+4
The LPCG clock indices for ASRC0 and AUD_PLL_DIV0 are swapped. The ASRC0 LPCG provides only IMX_LPCG_CLK_4, so update the ASRC0 clock consumer to use IMX_LPCG_CLK_4 instead of the non-existent IMX_LPCG_CLK_0. Likewise, the AUD_PLL_DIV0 LPCG provides only IMX_LPCG_CLK_0, so update its clock consumer to use IMX_LPCG_CLK_0 instead of the non-existent IMX_LPCG_CLK_4.
