2025-09-02drm/bridge: add drm_bridge_is_last()Luca Ceresoli1-0/+5
Some code needing to know whether a bridge is the last in a chain currently call drm_bridge_get_next_bridge(). However drm_bridge_get_next_bridge() will soon increment the refcount of the returned bridge, which would make such code more annoying to write. In preparation for drm_bridge_get_next_bridge() to increment the refcount, as well as to simplify such code, introduce a simple bool function to tell whether a bridge is the last in the chain.

2025-09-02fuse: allow synchronous FUSE_INITMiklos Szeredi1-0/+1
FUSE_INIT has always been asynchronous with mount. That means that the server processed this request after the mount syscall returned. This means that FUSE_INIT can't supply the root inode's ID, hence it currently has a hardcoded value. There are other limitations such as not being able to perform getxattr during mount, which is needed by selinux. To remove these limitations allow server to process FUSE_INIT while initializing the in-core super block for the fuse filesystem. This can only be done if the server is prepared to handle this, so add FUSE_DEV_IOC_SYNC_INIT ioctl, which a) lets the server know whether this feature is supported, returning ENOTTY othewrwise. b) lets the kernel know to perform a synchronous initialization The implementation is slightly tricky, since fuse_dev/fuse_conn are set up only during super block creation. This is solved by setting the private data of the fuse device file to a special value ((struct fuse_dev *) 1) and waiting for this to be turned into a proper fuse_dev before commecing with operations on the device file.

The s3c2410 NAND driver still supports S3C64xx platform, which in general is supported in the kernel. There are however no references of "s3c6400-nand" platform device ID or "s3c24xx-nand" driver, thus this driver cannot be instantiated for S3C64xx platform and is basically unused.

2025-09-01copy_process: pass clone_flags as u64 across calltreeSimon Schuster18-33/+33
With the introduction of clone3 in commit 7f192e3cd316 ("fork: add clone3") the effective bit width of clone_flags on all architectures was increased from 32-bit to 64-bit, with a new type of u64 for the flags. However, for most consumers of clone_flags the interface was not changed from the previous type of unsigned long. While this works fine as long as none of the new 64-bit flag bits (CLONE_CLEAR_SIGHAND and CLONE_INTO_CGROUP) are evaluated, this is still undesirable in terms of the principle of least surprise. Thus, this commit fixes all relevant interfaces of callees to sys_clone3/copy_process (excluding the architecture-specific copy_thread) to consistently pass clone_flags as u64, so that no truncation to 32-bit integers occurs on 32-bit architectures.

The number of pins is slightly different, but the programming model remains the same Add a new header, include/dt-bindings/gpio/tegra256-gpio.h, that defines port IDs as well as the TEGRA256_MAIN_GPIO() helper, both of which are used in conjunction to create a unique specifier for each pin. The OS can reconstruct the port ID and pin from these values to determine the register region for the corresponding GPIO. However, the OS does not use the macro definitions in this file. The symbolic names help associate these GPIO specifiers with the names used in the technical documentation available for the chip.

The <ufs/ufs.h> header file defines constants and data structures related to the UFS standard. Move the enumeration types related to tracing into a new header file because these are not defined in the UFS standard. An intended side effect of this patch is that the tracing enumeration types are no longer visible to UFS host drivers.

2025-08-31scsi: fc: Avoid -Wflex-array-member-not-at-end warningsGustavo A. R. Silva1-19/+39
-Wflex-array-member-not-at-end has been introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the '__struct_group()' helper to create a new tagged 'struct fc_df_desc_fpin_reg_hdr'. This structure groups together all the members of the flexible 'struct fc_df_desc_fpin_reg' except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct members currently causing trouble from 'struct fc_df_desc_fpin_reg' to 'struct fc_df_desc_fpin_reg_hdr'. We also want to ensure that in case new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use '_Static_assert()'. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement 'struct fc_df_desc_fpin_reg_hdr' as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. The above is also done for flexible structures 'struct fc_els_rdf' and 'struct fc_els_rdf_resp' So, with these changes, fix the following warnings: drivers/scsi/lpfc/lpfc_hw4.h:4936:41: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/scsi/lpfc/lpfc_hw4.h:4942:41: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/scsi/lpfc/lpfc_hw4.h:4947:41: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-08-29pppoe: remove rwlock usageQingfang Deng1-1/+1
Like ppp_generic.c, convert the PPPoE socket hash table to use RCU for lookups and a spinlock for updates. This removes rwlock usage and allows lockless readers on the fast path. - Mark hash table and list pointers as __rcu. - Use spin_lock() to protect writers. - Readers use rcu_dereference() under rcu_read_lock(). All known callers of get_item() already hold the RCU read lock, so no additional locking is needed. - get_item() now uses refcount_inc_not_zero() instead of sock_hold() to safely take a reference. This prevents crashes if a socket is already in the process of being freed (sk_refcnt == 0). - Set SOCK_RCU_FREE to defer socket freeing until after an RCU grace period. - Move skb_queue_purge() into sk_destruct callback to ensure purge happens after an RCU grace period.

As was done with the other algorithms, reorganize the BLAKE2s code so that the generic implementation and the arch-specific "glue" code is consolidated into a single translation unit, so that the compiler will inline the functions and automatically decide whether to include the generic code in the resulting binary or not. Similarly, also consolidate the build rules into lib/crypto/{Makefile,Kconfig}. This removes the last uses of lib/crypto/{arm,x86}/{Makefile,Kconfig}, so remove those too. Don't keep the !KMSAN dependency. It was needed only for other algorithms such as ChaCha that initialize memory from assembly code.

2025-08-29lib/crypto: chacha: Consolidate into single moduleEric Biggers1-24/+4
Consolidate the ChaCha code into a single module (excluding chacha-block-generic.c which remains always built-in for random.c), similar to various other algorithms: - Each arch now provides a header file lib/crypto/$(SRCARCH)/chacha.h, replacing lib/crypto/$(SRCARCH)/chacha*.c. The header defines chacha_crypt_arch() and hchacha_block_arch(). It is included by lib/crypto/chacha.c, and thus the code gets built into the single libchacha module, with improved inlining in some cases. - Whether arch-optimized ChaCha is buildable is now controlled centrally by lib/crypto/Kconfig instead of by lib/crypto/$(SRCARCH)/Kconfig. The conditions for enabling it remain the same as before, and it remains enabled by default. - Any additional arch-specific translation units for the optimized ChaCha code, such as assembly files, are now compiled by lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile. This removes the last use for the Makefile and Kconfig files in the arm64, mips, powerpc, riscv, and s390 subdirectories of lib/crypto/. So also remove those files and the references to them.
