2024-11-18net: ip: fix unexpected return in fib_validate_source()Menglong Dong

2024-11-18UAPI: ethtool: Avoid flex-array in struct ethtool_link_settingsKees Cook
struct ethtool_link_settings tends to be used as a header for other structures that have trailing bytes[1], but has a trailing flexible array itself. Using this overlapped with other structures leads to ambiguous object sizing in the compiler, so we want to avoid such situations (which have caused real bugs in the past). Detecting this can be done with -Wflex-array-member-not-at-end, which will need to be enabled globally. Using a tagged struct_group() to create a new ethtool_link_settings_hdr structure isn't possible as it seems we cannot use the tagged variant of struct_group() due to syntax issues from C++'s perspective (even within "extern C")[2]. Instead, we can just leave the offending member defined in UAPI and remove it from the kernel's view of the structure, as Linux doesn't actually use this member at all. There is also no change in size since it was already a flexible array that didn't contribute to size returned by any use of sizeof().

To return an endpoint to the userspace via Netlink, and to dump all of them, the endpoint list was iterated while holding the pernet->lock, but only to read the content of the list. In these cases, the spin locks can be replaced by RCU read ones, and use the _rcu variants to iterate over the entries list in a lockless way. Note that the __lookup_addr_by_id() helper has been modified to use the _rcu variants of list_for_each_entry(), but with an extra conditions, so it can be called either while the RCU read lock is held, or when the associated pernet->lock is held.

The err variable is not cleared, so if we find no table to dump we will return the validation error even if user did not want strict checking.

This is the first step to make s390 KVM page fault handling similar to other architectures. With this first step the main fault handler does not have any special handling anymore, and therefore convert it to support LOCK_MM_AND_FIND_VMA - With gcc 14 s390 support for flag output operand support for inline assemblies was added. This allows for several optimizations: - Provide a cmpxchg inline assembly which makes use of this, and provide all variants of arch_try_cmpxchg() so that the compiler can generate slightly better code - Convert a few cmpxchg() loops to try_cmpxchg() loops - Similar to x86 add a CC_OUT() helper macro (and other macros), and convert all inline assemblies to make use of them, so that depending on compiler version better code can be generated - List installed host-key hashes in sysfs if the machine supports the Query Ultravisor Keys UVC - Add 'Retrieve Secret' ioctl which allows user space in protected execution guests to retrieve previously stored secrets from the Ultravisor - Add pkey-uv module which supports the conversion of Ultravisor retrievable secrets to protected keys - Extend the existing paes cipher to exploit the full AES-XTS hardware acceleration introduced with message-security assist extension 10 - Convert hopefully all sysfs show functions to use sysfs_emit() so that the constant flow of such patches stop - For PCI devices make use of the newly added Topology ID attribute to enable whole card multi-function support despite the change to PCHID per port.

There are limitations involving generic netlink due to the multiplexing that is done, but it's no worse that what we currently have. As usual, more information can be found in the commit message. - Deprecate /sys/fs/selinux/user We removed the only known userspace use of this back in 2020 and now that several years have elapsed we're starting down the path of deprecating it in the kernel. - Cleanup the build under scripts/selinux A couple of patches to move the genheaders tool under security/selinux and correct our usage of kernel headers in the tools located under scripts/selinux.

Pull io_uring updates from Jens Axboe: - Cleanups of the eventfd handling code, making it fully private. - Support for sending a sync message to another ring, without having a ring available to send a normal async message. - Get rid of the separate unlocked hash table, unify everything around the single locked one. - Add support for ring resizing. It can be hard to appropriately size the CQ ring upfront, if the application doesn't know how busy it will be. This results in applications sizing rings for the most busy case, which can be wasteful. With ring resizing, they can start small and grow the ring, if needed. - Add support for fixed wait regions, rather than needing to copy the same wait data tons of times for each wait operation. - Rewrite the resource node handling, which before was serialized per ring. This caused issues with particularly fixed files, where one file waiting on IO could hold up putting and freeing of other unrelated files. Now each node is handled separately. New code is much simpler too, and was a net 250 line reduction in code. - Add support for just doing partial buffer clones, rather than always cloning the entire buffer table. - Series adding static NAPI support, where a specific NAPI instance is used rather than having a list of them available that need lookup. - Add support for mapped regions, and also convert the fixed wait support mentioned above to that concept. This avoids doing special mappings for various planned features, and folds the existing registered wait into that too. - Add support for hybrid IO polling, which is a variant of strict IOPOLL but with an initial sleep delay to avoid spinning too early and wasting resources on devices that aren't necessarily in the < 5 usec category wrt latencies. - Various cleanups and little fixes. * tag 'for-6.13/io_uring-20241118' of git://git.kernel.dk/linux: (79 commits) io_uring/region: fix error codes after failed vmap io_uring: restore back registered wait arguments io_uring: add memory region registration io_uring: introduce concept of memory regions io_uring: temporarily disable registered waits io_uring: disable ENTER_EXT_ARG_REG for IOPOLL io_uring: fortify io_pin_pages with a warning switch io_msg_ring() to CLASS(fd) io_uring: fix invalid hybrid polling ctx leaks io_uring/uring_cmd: fix buffer index retrieval io_uring/rsrc: add & apply io_req_assign_buf_node() io_uring/rsrc: remove '->ctx_ptr' of 'struct io_rsrc_node' io_uring/rsrc: pass 'struct io_ring_ctx' reference to rsrc helpers io_uring: avoid normal tw intermediate fallback io_uring/napi: add static napi tracking strategy io_uring/napi: clean up __io_napi_do_busy_loop io_uring/napi: Use lock guards io_uring/napi: improve __io_napi_add io_uring/napi: fix io_napi_entry RCU accesses io_uring/napi: protect concurrent io_napi_entry timeout accesses ...
