a430d95 Linus Torvalds 16 September 2024, 16:19:47 UTC Merge tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull lsm updates from Paul Moore: - Move the LSM framework to static calls This transitions the vast majority of the LSM callbacks into static calls. Those callbacks which haven't been converted were left as-is due to the general ugliness of the changes required to support the static call conversion; we can revisit those callbacks at a future date. - Add the Integrity Policy Enforcement (IPE) LSM This adds a new LSM, Integrity Policy Enforcement (IPE). There is plenty of documentation about IPE in this patches, so I'll refrain from going into too much detail here, but the basic motivation behind IPE is to provide a mechanism such that administrators can restrict execution to only those binaries which come from integrity protected storage, e.g. a dm-verity protected filesystem. You will notice that IPE requires additional LSM hooks in the initramfs, dm-verity, and fs-verity code, with the associated patches carrying ACK/review tags from the associated maintainers. We couldn't find an obvious maintainer for the initramfs code, but the IPE patchset has been widely posted over several years. Both Deven Bowers and Fan Wu have contributed to IPE's development over the past several years, with Fan Wu agreeing to serve as the IPE maintainer moving forward. Once IPE is accepted into your tree, I'll start working with Fan to ensure he has the necessary accounts, keys, etc. so that he can start submitting IPE pull requests to you directly during the next merge window. - Move the lifecycle management of the LSM blobs to the LSM framework Management of the LSM blobs (the LSM state buffers attached to various kernel structs, typically via a void pointer named "security" or similar) has been mixed, some blobs were allocated/managed by individual LSMs, others were managed by the LSM framework itself. Starting with this pull we move management of all the LSM blobs, minus the XFRM blob, into the framework itself, improving consistency across LSMs, and reducing the amount of duplicated code across LSMs. Due to some additional work required to migrate the XFRM blob, it has been left as a todo item for a later date; from a practical standpoint this omission should have little impact as only SELinux provides a XFRM LSM implementation. - Fix problems with the LSM's handling of F_SETOWN The LSM hook for the fcntl(F_SETOWN) operation had a couple of problems: it was racy with itself, and it was disconnected from the associated DAC related logic in such a way that the LSM state could be updated in cases where the DAC state would not. We fix both of these problems by moving the security_file_set_fowner() hook into the same section of code where the DAC attributes are updated. Not only does this resolve the DAC/LSM synchronization issue, but as that code block is protected by a lock, it also resolve the race condition. - Fix potential problems with the security_inode_free() LSM hook Due to use of RCU to protect inodes and the placement of the LSM hook associated with freeing the inode, there is a bit of a challenge when it comes to managing any LSM state associated with an inode. The VFS folks are not open to relocating the LSM hook so we have to get creative when it comes to releasing an inode's LSM state. Traditionally we have used a single LSM callback within the hook that is triggered when the inode is "marked for death", but not actually released due to RCU. Unfortunately, this causes problems for LSMs which want to take an action when the inode's associated LSM state is actually released; so we add an additional LSM callback, inode_free_security_rcu(), that is called when the inode's LSM state is released in the RCU free callback. - Refactor two LSM hooks to better fit the LSM return value patterns The vast majority of the LSM hooks follow the "return 0 on success, negative values on failure" pattern, however, there are a small handful that have unique return value behaviors which has caused confusion in the past and makes it difficult for the BPF verifier to properly vet BPF LSM programs. This includes patches to convert two of these"special" LSM hooks to the common 0/-ERRNO pattern. - Various cleanups and improvements A handful of patches to remove redundant code, better leverage the IS_ERR_OR_NULL() helper, add missing "static" markings, and do some minor style fixups. * tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (40 commits) security: Update file_set_fowner documentation fs: Fix file_set_fowner LSM hook inconsistencies lsm: Use IS_ERR_OR_NULL() helper function lsm: remove LSM_COUNT and LSM_CONFIG_COUNT ipe: Remove duplicated include in ipe.c lsm: replace indirect LSM hook calls with static calls lsm: count the LSMs enabled at compile time kernel: Add helper macros for loop unrolling init/main.c: Initialize early LSMs after arch code, static keys and calls.

While KCSAN is correct, it is an intentional choice made for performance reasons; if necessary, we check the state a second time, this time with a lock held, before initializing the inode's state. - Code cleanups, simplification, etc. A handful of individual patches to simplify some SELinux kernel logic, improve return code granularity via ERR_PTR(), follow the guidance on using KMEM_CACHE(), and correct some minor style problems. * tag 'selinux-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: fix style problems in security/selinux/include/audit.h selinux: simplify avc_xperms_audit_required() selinux: mark both IPv4 and IPv6 accepted connection sockets as labeled selinux: replace kmem_cache_create() with KMEM_CACHE() selinux: annotate false positive data race to avoid KCSAN warnings selinux: refactor code to return ERR_PTR in selinux_netlbl_sock_genattr selinux: Streamline type determination in security_compute_sid 16 September 2024, 14:55:42 UTC

This commit shifts the audit PID logging and filtering to use the TGID value which should provide a more meaningful audit stream and filtering experience for users. - Migrate to the str_enabled_disabled() helper Evidently we have helper functions that help ensure if we mistype "enabled" or "disabled" it is now caught at compile time.

43a64bd David Howells 16 September 2024, 14:02:06 UTC cifs: Remove redundant setting of NETFS_SREQ_HIT_EOF Fix an upstream merge resolution issue[1]. The NETFS_SREQ_HIT_EOF flag, and code to set it, got added via two different paths. The original path saw it added in the netfslib read improvements[2], but it was also added, and slightly differently, in a fix that was committed before v6.11: 1da29f2c39b67b846b74205c81bf0ccd96d34727 netfs, cifs: Fix handling of short DIO read However, the code added to smb2_readv_callback() to set the flag in didn't get removed when the netfs read improvements series was rebased to take account of the cifs fixes. The proposed merge resolution[2] deleted it rather than rebase the patches. Fix this by removing the redundant lines. Code to set the bit that derives from the fix patch is still there, a few lines above in the source.

dc1a456 David Howells 16 September 2024, 13:50:16 UTC cifs: Fix cifs readv callback merge resolution issue Fix an upstream merge resolution issue[1]. Prior to the netfs read healpers, the SMB1 asynchronous read callback, cifs_readv_worker() performed the cleanup for the operation in the network message processing loop, potentially slowing down the processing of incoming SMB messages. With commit a68c74865f51 ("cifs: Fix SMB1 readv/writev callback in the same way as SMB2/3"), this was moved to a worker thread (as is done in the SMB2/3 transport variant). However, the "was_async" argument to netfs_subreq_terminated (which was originally incorrectly "false" got flipped to "true" - which was then incorrect because, being in a kernel thread, it's not in an async context). This got corrected in the sample merge[2], but Linus, not unreasonably, switched it back to its previous value. Note that this value tells netfslib whether or not it can run sleepable stuff or stuff that takes a long time, such as retries and cleanups, in the calling thread, or whether it should offload to a worker thread. Fix this so that it is "false". The callback to netfslib in both SMB1 and SMB2/3 now gets offloaded from the network message thread to a separate worker thread and thus it's fine to do the slow work in this thread.

69a3a0a Linus Torvalds 16 September 2024, 11:17:11 UTC Merge tag 'erofs-for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs Pull erofs updates from Gao Xiang: "In this cycle, we add file-backed mount support, which has has been a strong requirement for years. It is especially useful when there are thousands of images running on the same host for containers and other sandbox use cases, unlike OS image use cases. Without file-backed mounts, it's hard for container runtimes to manage and isolate so many unnecessary virtual block devices safely and efficiently, therefore file-backed mounts are highly preferred. For EROFS users, ComposeFS [1], containerd, and Android APEXes [2] will directly benefit from it, and I've seen no risk in implementing it as a completely immutable filesystem. The previous experimental feature "EROFS over fscache" is now marked as deprecated because: - Fscache is no longer an independent subsystem and has been merged into netfs, which was somewhat unexpected when it was proposed. - New HSM "fanotify pre-content hooks" [3] will be landed upstream. These hooks will replace "EROFS over fscache" in a simpler way, as EROFS won't be bother with kernel caching anymore. Userspace programs can also manage their own caching hierarchy more flexibly. Once the HSM "fanotify pre-content hooks" is landed, I will remove the fscache backend entirely as an internal dependency cleanup. More backgrounds are listed in the original patchset [4]. In addition to that, there are bugfixes and cleanups as usual. Summary: - Support file-backed mounts for containers and sandboxes - Mark the experimental fscache backend as deprecated - Handle overlapped pclusters caused by crafted images properly - Fix a failure path which could cause infinite loops in z_erofs_init_decompressor() - Get rid of unnecessary NOFAILs - Harmless on-disk hardening & minor cleanups" * tag 'erofs-for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: erofs: reject inodes with negative i_size erofs: restrict pcluster size limitations erofs: allocate more short-lived pages from reserved pool first erofs: sunset unneeded NOFAILs erofs: simplify erofs_map_blocks_flatmode() erofs: refactor read_inode calling convention erofs: use kmemdup_nul in erofs_fill_symlink erofs: mark experimental fscache backend deprecated erofs: support compressed inodes for fileio erofs: support unencoded inodes for fileio erofs: add file-backed mount support erofs: handle overlapped pclusters out of crafted images properly erofs: fix error handling in z_erofs_init_decompressor erofs: clean up erofs_register_sysfs() erofs: fix incorrect symlink detection in fast symlink 16 September 2024, 11:17:11 UTC

The folio API conversions are most noticeable. There's one less visible change that could have a high impact. The extent lock scope for read is reduced, not held for the entire operation. In the buffered read case it's left to page or inode lock, some direct io read synchronization is still needed. This used to prevent deadlocks induced by page faults during direct io, so there was a 4K limitation on the requests, e.g. for io_uring. In the future this will allow smoother integration with iomap where the extent read lock was a major obstacle. User visible changes: - the FSTRIM ioctl updates the processed range even after an error or interruption - cleaner thread is woken up in SYNC ioctl instead of waking the transaction thread that can take some delay before waking up the cleaner, this can speed up cleaning of deleted subvolumes - print an error message when opening a device fail, e.g. when it's unexpectedly read-only Core changes: - improved extent map handling in various ways (locking, iteration, ...) - new assertions and locking annotations - raid-stripe-tree locking fixes - use xarray for tracking dirty qgroup extents, switched from rb-tree - turn the subpage test to compile-time condition if possible (e.g. on x86_64 with 4K pages), this allows to skip a lot of ifs and remove dead code - more preparatory work for compression in subpage mode Cleanups and refactoring - folio API conversions, many simple cases where page is passed so switch it to folios - more subpage code refactoring, update page state bitmap processing - introduce auto free for btrfs_path structure, use for the simple cases" * tag 'for-6.12-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (110 commits) btrfs: only unlock the to-be-submitted ranges inside a folio btrfs: merge btrfs_folio_unlock_writer() into btrfs_folio_end_writer_lock() btrfs: BTRFS_PATH_AUTO_FREE in orphan.c btrfs: use btrfs_path auto free in zoned.c btrfs: DEFINE_FREE for struct btrfs_path btrfs: remove btrfs_folio_end_all_writers() btrfs: constify more pointer parameters btrfs: rework BTRFS_I as macro to preserve parameter const btrfs: add and use helper to verify the calling task has locked the inode btrfs: always update fstrim_range on failure in FITRIM ioctl btrfs: convert copy_inline_to_page() to use folio btrfs: convert btrfs_decompress() to take a folio btrfs: convert zstd_decompress() to take a folio btrfs: convert lzo_decompress() to take a folio btrfs: convert zlib_decompress() to take a folio btrfs: convert try_release_extent_mapping() to take a folio btrfs: convert try_release_extent_state() to take a folio btrfs: convert submit_eb_page() to take a folio btrfs: convert submit_eb_subpage() to take a folio btrfs: convert read_key_bytes() to take a folio ... 16 September 2024, 11:10:46 UTC

35219bc Linus Torvalds 16 September 2024, 10:13:31 UTC Merge tag 'vfs-6.12.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull netfs updates from Christian Brauner: "This contains the work to improve read/write performance for the new netfs library. The main performance enhancing changes are: - Define a structure, struct folio_queue, and a new iterator type, ITER_FOLIOQ, to hold a buffer as a replacement for ITER_XARRAY. See that patch for questions about naming and form. ITER_FOLIOQ is provided as a replacement for ITER_XARRAY. The problem with an xarray is that accessing it requires the use of a lock (typically the RCU read lock) - and this means that we can't supply iterate_and_advance() with a step function that might sleep (crypto for example) without having to drop the lock between pages. ITER_FOLIOQ is the iterator for a chain of folio_queue structs, where each folio_queue holds a small list of folios. A folio_queue struct is a simpler structure than xarray and is not subject to concurrent manipulation by the VM. folio_queue is used rather than a bvec[] as it can form lists of indefinite size, adding to one end and removing from the other on the fly. - Provide a copy_folio_from_iter() wrapper. - Make cifs RDMA support ITER_FOLIOQ. - Use folio queues in the write-side helpers instead of xarrays. - Add a function to reset the iterator in a subrequest. - Simplify the write-side helpers to use sheaves to skip gaps rather than trying to work out where gaps are. - In afs, make the read subrequests asynchronous, putting them into work items to allow the next patch to do progressive unlocking/reading. - Overhaul the read-side helpers to improve performance. - Fix the caching of a partial block at the end of a file. - Allow a store to be cancelled.

This extends nsfs in two ways: (1) Add the ability to retrieve information about a mount namespace via NS_MNT_GET_INFO. This will return the mount namespace id and the number of mounts currently in the mount namespace. The number of mounts can be used to size the buffer that needs to be used for listmount() and is in general useful without having to actually iterate through all the mounts. The structure is extensible. (2) Add the ability to iterate through all mount namespaces over which the caller holds privilege returning the file descriptor for the next or previous mount namespace. To retrieve a mount namespace the caller must be privileged wrt to it's owning user namespace. This means that PID 1 on the host can list all mounts in all mount namespaces or that a container can list all mounts of its nested containers. Optionally pass a structure for NS_MNT_GET_INFO with NS_MNT_GET_{PREV,NEXT} to retrieve information about the mount namespace in one go. (1) and (2) can be implemented for other namespace types easily. Together with recent api additions this means one can iterate through all mounts in all mount namespaces without ever touching procfs.

This adds a Kconfig option and boot param to allow removing the FOLL_FORCE flag from /proc/<pid>/mem write calls as this can be used in various attacks. The traditional forcing behavior is kept as default because it can break GDB and some other use cases. This is the simpler version that you had requested. - Restrict overmounting of ephemeral entities. It is currently possible to mount on top of various ephemeral entities in procfs. This specifically includes magic links. To recap, magic links are links of the form /proc/<pid>/fd/<nr>. They serve as references to a target file and during path lookup they cause a jump to the target path. Such magic links disappear if the corresponding file descriptor is closed. Currently it is possible to overmount such magic links. This is mostly interesting for an attacker that wants to somehow trick a process into e.g., reopening something that it didn't intend to reopen or to hide a malicious file descriptor. But also it risks leaking mounts for long-running processes. When overmounting a magic link like above, the mount will not be detached when the file descriptor is closed. Only the target mountpoint will disappear. Which has the consequence of making it impossible to unmount that mount afterwards. So the mount will stick around until the process exits and the /proc/<pid>/ directory is cleaned up during proc_flush_pid() when the dentries are pruned and invalidated. That in turn means it's possible for a program to accidentally leak mounts and it's also possible to make a task leak mounts without it's knowledge if the attacker just keeps overmounting things under /proc/<pid>/fd/<nr>. Disallow overmounting of such ephemeral entities. - Cleanup the readdir method naming in some procfs file operations. - Replace kmalloc() and strcpy() with a simple kmemdup() call" * tag 'vfs-6.12.procfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: proc: fold kmalloc() + strcpy() into kmemdup() proc: block mounting on top of /proc/<pid>/fdinfo/* proc: block mounting on top of /proc/<pid>/fd/* proc: block mounting on top of /proc/<pid>/map_files/* proc: add proc_splice_unmountable() proc: proc_readfdinfo() -> proc_fdinfo_iterate() proc: proc_readfd() -> proc_fd_iterate() proc: add config & param to block forcing mem writes 16 September 2024, 07:36:59 UTC

Right now, (focusing on x86) struct file is 232 bytes. After this series struct file will be 184 bytes aka 3 cacheline and a spare 8 bytes for future extensions at the end of the struct. With struct file being as ubiquitous as it is this should make a difference for file heavy workloads and allow further optimizations in the future. - struct fown_struct was embedded into struct file letting it take up 32 bytes in total when really it shouldn't even be embedded in struct file in the first place. Instead, actual users of struct fown_struct now allocate the struct on demand. This frees up 24 bytes. - Move struct file_ra_state into the union containg the cleanup hooks and move f_iocb_flags out of the union. This closes a 4 byte hole we created earlier and brings struct file to 192 bytes. Which means struct file is 3 cachelines and we managed to shrink it by 40 bytes. - Reorder struct file so that nothing crosses a cacheline. I suspect that in the future we will end up reordering some members to mitigate false sharing issues or just because someone does actually provide really good perf data. - Shrinking struct file to 192 bytes is only part of the work. Files use a slab that is SLAB_TYPESAFE_BY_RCU and when a kmem cache is created with SLAB_TYPESAFE_BY_RCU the free pointer must be located outside of the object because the cache doesn't know what part of the memory can safely be overwritten as it may be needed to prevent object recycling. That has the consequence that SLAB_TYPESAFE_BY_RCU may end up adding a new cacheline. So this also contains work to add a new kmem_cache_create_rcu() function that allows the caller to specify an offset where the freelist pointer is supposed to be placed. Thus avoiding the implicit addition of a fourth cacheline. - And finally this removes the f_version member in struct file. The f_version member isn't particularly well-defined. It is mainly used as a cookie to detect concurrent seeks when iterating directories. But it is also abused by some subsystems for completely unrelated things. It is mostly a directory and filesystem specific thing that doesn't really need to live in struct file and with its wonky semantics it really lacks a specific function. For pipes, f_version is (ab)used to defer poll notifications until a write has happened. And struct pipe_inode_info is used by multiple struct files in their ->private_data so there's no chance of pushing that down into file->private_data without introducing another pointer indirection. But pipes don't rely on f_pos_lock so this adds a union into struct file encompassing f_pos_lock and a pipe specific f_pipe member that pipes can use. This union of course can be extended to other file types and is similar to what we do in struct inode already" * tag 'vfs-6.12.file' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (26 commits) fs: remove f_version pipe: use f_pipe fs: add f_pipe ubifs: store cookie in private data ufs: store cookie in private data udf: store cookie in private data proc: store cookie in private data ocfs2: store cookie in private data input: remove f_version abuse ext4: store cookie in private data ext2: store cookie in private data affs: store cookie in private data fs: add generic_llseek_cookie() fs: use must_set_pos() fs: add must_set_pos() fs: add vfs_setpos_cookie() s390: remove unused f_version ceph: remove unused f_version adi: remove unused f_version mm: Removed @freeptr_offset to prevent doc warning ... 16 September 2024, 07:14:02 UTC

Often userspace wants to know whether an O_CREATE request did actually create a file without using O_EXCL. The current logic is that to first attempts to open the file without O_CREAT | O_EXCL and if ENOENT is returned userspace tries again with both flags. If that succeeds all is well. If it now reports EEXIST it retries. That works fairly well but some corner cases make this more involved. If this operates on a dangling symlink the first openat() without O_CREAT | O_EXCL will return ENOENT but the second openat() with O_CREAT | O_EXCL will fail with EEXIST. The reason is that openat() without O_CREAT | O_EXCL follows the symlink while O_CREAT | O_EXCL doesn't for security reasons. So it's not something we can really change unless we add an explicit opt-in via O_FOLLOW which seems really ugly. All available workarounds are really nasty (fanotify, bpf lsm etc) so add a simple fcntl(). - Try an opportunistic lookup for O_CREAT. Today, when opening a file we'll typically do a fast lookup, but if O_CREAT is set, the kernel always takes the exclusive inode lock. This was likely done with the expectation that O_CREAT means that we always expect to do the create, but that's often not the case. Many programs set O_CREAT even in scenarios where the file already exists (see related F_CREATED_QUERY patch motivation above). The series contained in the pr rearranges the pathwalk-for-open code to also attempt a fast_lookup in certain O_CREAT cases. If a positive dentry is found, the inode_lock can be avoided altogether and it can stay in rcuwalk mode for the last step_into. - Expose the 64 bit mount id via name_to_handle_at() Now that we provide a unique 64-bit mount ID interface in statx(2), we can now provide a race-free way for name_to_handle_at(2) to provide a file handle and corresponding mount without needing to worry about racing with /proc/mountinfo parsing or having to open a file just to do statx(2). While this is not necessary if you are using AT_EMPTY_PATH and don't care about an extra statx(2) call, users that pass full paths into name_to_handle_at(2) need to know which mount the file handle comes from (to make sure they don't try to open_by_handle_at a file handle from a different filesystem) and switching to AT_EMPTY_PATH would require allocating a file for every name_to_handle_at(2) call - Add a per dentry expire timeout to autofs There are two fairly well known automounter map formats, the autofs format and the amd format (more or less System V and Berkley). Some time ago Linux autofs added an amd map format parser that implemented a fair amount of the amd functionality. This was done within the autofs infrastructure and some functionality wasn't implemented because it either didn't make sense or required extra kernel changes. The idea was to restrict changes to be within the existing autofs functionality as much as possible and leave changes with a wider scope to be considered later. One of these changes is implementing the amd options: 1) "unmount", expire this mount according to a timeout (same as the current autofs default). 2) "nounmount", don't expire this mount (same as setting the autofs timeout to 0 except only for this specific mount) . 3) "utimeout=<seconds>", expire this mount using the specified timeout (again same as setting the autofs timeout but only for this mount) To implement these options per-dentry expire timeouts need to be implemented for autofs indirect mounts. This is because all map keys (mounts) for autofs indirect mounts use an expire timeout stored in the autofs mount super block info. structure and all indirect mounts use the same expire timeout.

Previously we only supported on matching TOS bits in IPv4 which is a narrower interpretation of the same header field. - Increase the range of weights used for multi-path routing from 8 bits to 16 bits. - Add support for IPv6 PIO p flag in the Prefix Information Option per draft-ietf-6man-pio-pflag. - IPv6 IOAM6 support for new tunsrc encap mode for better performance. - Detect destinations which blackhole MPTCP traffic and avoid initiating MPTCP connections to them for a certain period of time, 1h by default. - Improve IPsec control path performance by removing the inexact policies list. - AF_VSOCK: add support for SIOCOUTQ ioctl. - Add enum for reasons TCP reset was sent for easier tracing. - Add SMC ringbufs usage statistics. Drivers: - Handle netconsole setup failures more gracefully, don't fail loading, retain the specified target as disabled. - Extend bonding's IPsec offload pass thru capabilities (ESN, stats). Filtering: - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case when long-lived sockets miss a chance to set additional callbacks if a sockops program was not attached early in their lifetime. - Support using BPF skb helpers in tracepoints. - Conntrack Netlink: support CTA_FILTER for flush. - Improve SCTP support in nfnetlink_queue. - Improve performance of large nftables flush transactions. Things we sprinkled into general kernel code: - selftests: support setting an "interpreter" for script files; make it easy to run as separate cases tests where one "interpreter" is fed various test descriptions (in our case packet sequences). Driver API: - Extend core and ethtool APIs to support many PHYs connected to a single interface (PHY topologies). - Extend cable diagnostics to specify whether Time Domain Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was used. - Add library for implementing MAC-PHY Ethernet drivers for SPI devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial Interface (TC6) standard. - Add helpers to the PHY framework, for PHYs following the Open Alliance standards: - 1000BaseT1 link settings - cable test and diagnostics - Support listing / dumping all allocated RSS contexts. - Add configuration for frequency Embedded SYNC in DPLL, which magically embeds sync pulses into Ethernet signaling.

9d70f3f Paolo Bonzini 15 September 2024, 06:49:33 UTC Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop" This reverts commit 377b2f359d1f71c75f8cc352b5c81f2210312d83. This caused a regression with the bochsdrm driver, which used ioremap() instead of ioremap_wc() to map the video RAM. After the commit, the WB memory type is used without the IGNORE_PAT, resulting in the slower UC memory type. In fact, UC is slow enough to basically cause guests to not boot... but only on new processors such as Sapphire Rapids and Cascade Lake. Coffee Lake for example works properly, though that might also be an effect of being on a larger, more NUMA system. The driver has been fixed but that does not help older guests. Until we figure out whether Cascade Lake and newer processors are working as intended, revert the commit. Long term we might add a quirk, but the details depend on whether the processors are working as intended: for example if they are, the quirk might reference bochs-compatible devices, e.g. in the name and documentation, so that userspace can disable the quirk by default and only leave it enabled if such a device is being exposed to the guest. If instead this is actually a bug in CLX+, then the actions we need to take are different and depend on the actual cause of the bug.

The reason for that is that historically users of the FIB lookup API only populated the lower three DSCP bits in the TOS field of the IPv4 flow key ('flowi4_tos'), which fits the TOS definition from the initial IPv4 specification (RFC 791). This is not very useful nowadays and instead some users want to be able to match on the six bits DSCP field, which replaced the TOS and IP precedence fields over 25 years ago (RFC 2474). In addition, the current behavior differs between IPv4 and IPv6 which does allow users to match on the entire DSCP field using the TOS selector. Recent patchsets made sure that callers of the FIB lookup API now populate the entire DSCP field in the IPv4 flow key. Therefore, it is now possible to extend FIB rules to match on DSCP. This is done by adding a new DSCP attribute which is implemented for both IPv4 and IPv6 to provide user space programs a consistent behavior between both address families. The behavior of the old TOS selector is unchanged and IPv4 FIB rules using it will only match on the lower three DSCP bits. The kernel will reject rules that try to use both selectors. Patch #1 adds the new DSCP attribute but rejects its usage. Patches #2-#3 implement IPv4 and IPv6 support. Patch #4 allows user space to use the new attribute.

Add relevant error messages where applicable, allowing user space to better understand the issues encountered.

At the end of netif_napi_add_weight() is a call to netif_napi_set_irq(napi, -1), which clears the previously set napi->irq value. Fix this by calling netif_napi_set_irq() after calling netif_napi_add(). This was found when reviewing another patch and I have no way to test this, but the fix seemed relatively straight forward.

The 3s threshold rang a bell, as this is the delay after which ALDPS kicks in. And indeed disabling ALDPS fixes the issue for this user. Maybe this fixes the issue in general.

4144a10 Maciej Fijalkowski 11 September 2024, 19:10:19 UTC xsk: fix batch alloc API on non-coherent systems In cases when synchronizing DMA operations is necessary, xsk_buff_alloc_batch() returns a single buffer instead of the requested count. This puts the pressure on drivers that use batch API as they have to check for this corner case on their side and take care of allocations by themselves, which feels counter productive. Let us improve the core by looping over xp_alloc() @max times when slow path needs to be taken. Another issue with current interface, as spotted and fixed by Dries, was that when driver called xsk_buff_alloc_batch() with @max == 0, for slow path case it still allocated and returned a single buffer, which should not happen. By introducing the logic from first paragraph we kill two birds with one stone and address this problem as well.
