2023-04-24net: ethtool: coalesce: try to make user settings stick twiceJakub Kicinski
SET_COALESCE may change operation mode and parameters in one call. Changing operation mode may cause the driver to reset the parameter values to what is a reasonable default for new operation mode. Since driver does not know which parameters come from user and which are echoed back from ->get, driver may ignore the parameters when switching operation modes. This used to be inevitable for ioctl() but in netlink we know which parameters are actually specified by the user. We could inform which parameters were set by the user but this would lead to a lot of code duplication in the drivers. Instead try to call the drivers twice if both mode and params are changed. The set method already checks if any params need updating so in case the driver did the right thing the first time around - there will be no second call to it's ->set method (only an extra call to ->get()). For mlx5 for example before this patch we'd see: # ethtool -C eth0 adaptive-rx on adaptive-tx on # ethtool -C eth0 adaptive-rx off adaptive-tx off \ tx-usecs 123 rx-usecs 123 Adaptive RX: off TX: off rx-usecs: 3 rx-frames: 32 tx-usecs: 16 tx-frames: 32 [...] After the change: # ethtool -C eth0 adaptive-rx on adaptive-tx on # ethtool -C eth0 adaptive-rx off adaptive-tx off \ tx-usecs 123 rx-usecs 123 Adaptive RX: off TX: off rx-usecs: 123 rx-frames: 32 tx-usecs: 123 tx-frames: 32 [...] This only works for netlink, so it's a small discrepancy between netlink and ioctl(). Since we anticipate most users to move to netlink I believe it's worth making their lives easier.

git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs Pull erofs updates from Gao Xiang: "In this cycle, sub-page block support for uncompressed files is available. It's mainly used to enable original signing ('golden') 4k-block images on arm64 with 16/64k pages. In addition, end users could also use this feature to build a manifest to directly refer to golden tar data. Besides, long xattr name prefix support is also introduced in this cycle to avoid too many xattrs with the same prefix (e.g. overlayfs xattrs). It's useful for erofs + overlayfs combination (like Composefs model): the image size is reduced by ~14% and runtime performance is also slightly improved. Others are random fixes and cleanups as usual. Summary: - Add sub-page block size support for uncompressed files - Support flattened block device for multi-blob images to be attached into virtual machines (including cloud servers) and bare metals - Support long xattr name prefixes to optimize images with common xattr namespaces (e.g. files with overlayfs xattrs) use cases - Various minor cleanups & fixes" * tag 'erofs-for-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: erofs: cleanup i_format-related stuffs erofs: sunset erofs_dbg() erofs: fix potential overflow calculating xattr_isize erofs: get rid of z_erofs_fill_inode() erofs: enable long extended attribute name prefixes erofs: handle long xattr name prefixes properly erofs: add helpers to load long xattr name prefixes erofs: introduce on-disk format for long xattr name prefixes erofs: move packed inode out of the compression part erofs: keep meta inode into erofs_buf erofs: initialize packed inode after root inode is assigned erofs: stop parsing non-compact HEAD index if clusterofs is invalid erofs: don't warn ztailpacking feature anymore erofs: simplify erofs_xattr_generic_get() erofs: rename init_inode_xattrs with erofs_ prefix erofs: move several xattr helpers into xattr.c erofs: tidy up EROFS on-disk naming erofs: support flattened block device for multi-blob images erofs: set block size to the on-disk block size erofs: avoid hardcoded blocksize for subpage block support

All custom helpers are removed (Jeff) - Fsnotify now reports ACCESS and MODIFY events for splice (Chung-Chiang Cheng) - After converting timerfd a long time ago to rely on wait_event_interruptible_*() apis, convert eventfd as well. This removes the complex open-coded wait code (Wen Yang) - Simplify sysctl registration for devpts, avoiding the declaration of two tables.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux updates from Paul Moore: - Stop passing the 'selinux_state' pointers as function arguments As discussed during the end of the last development cycle, passing a selinux_state pointer through the SELinux code has a noticeable impact on performance, and with the current code it is not strictly necessary. This simplifies things by referring directly to the single selinux_state global variable which should help improve SELinux performance. - Uninline the unlikely portions of avc_has_perm_noaudit() This change was also based on a discussion from the last development cycle, and is heavily based on an initial proof of concept patch from you. The core issue was that avc_has_perm_noaudit() was not able to be inlined, as intended, due to its size. We solved this issue by extracting the less frequently hit portions of avc_has_perm_noaudit() into a separate function, reducing the size of avc_has_perm_noaudit() to the point where the compiler began inlining the function. We also took the opportunity to clean up some ugly RCU locking in the code that became uglier with the change. - Remove the runtime disable functionality After several years of work by the userspace and distro folks, we are finally in a place where we feel comfortable removing the runtime disable functionality which we initially deprecated at the start of 2020. There is plenty of information in the kernel's deprecation (now removal) notice, but the main motivation was to be able to safely mark the LSM hook structures as '__ro_after_init'. LWN also wrote a good summary of the deprecation this morning which offers a more detailed history: https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03 - Remove the checkreqprot functionality The original checkreqprot deprecation notice stated that the removal would happen no sooner than June 2021, which means this falls hard into the "better late than never" bucket. The Kconfig and deprecation notice has more detail on this setting, but the basic idea is that we want to ensure that the SELinux policy allows for the memory protections actually applied by the kernel, and not those requested by the process. While we haven't found anyone running a supported distro that is affected by this deprecation/removal, anyone who is affected would only need to update their policy to reflect the reality of their applications' mapping protections. - Minor Makefile improvements Some minor Makefile improvements to correct some dependency issues likely only ever seen by SELinux developers. I expect we will have at least one more tweak to the Makefile during the next merge window, but it didn't quite make the cutoff this time around. * tag 'selinux-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: ensure av_permissions.h is built when needed selinux: fix Makefile dependencies of flask.h selinux: stop returning node from avc_insert() selinux: clean up dead code after removing runtime disable selinux: update the file list in MAINTAINERS selinux: remove the runtime disable functionality selinux: remove the 'checkreqprot' functionality selinux: stop passing selinux_state pointers and their offspring selinux: uninline unlikely parts of avc_has_perm_noaudit()

2023-04-22rxrpc: Fix potential race in error handling in afs_make_call()David Howells
If the rxrpc call set up by afs_make_call() receives an error whilst it is transmitting the request, there's the possibility that it may get to the point the rxrpc call is ended (after the error_kill_call label) just as the call is queued for async processing. This could manifest itself as call->rxcall being seen as NULL in afs_deliver_to_call() when it tries to lock the call. Fix this by splitting rxrpc_kernel_end_call() into a function to shut down an rxrpc call and a function to release the caller's reference and calling the latter only when we get to afs_put_call().

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-04-20 1) Dragos Improves RX page pool, and provides some fixes to his previous series: 1.1) Fix releasing page_pool for striding RQ and legacy RQ nonlinear case 1.2) Hook NAPIs to page pools to gain more performance. 2) From Roi, Some cleanups to TC and eswitch modules. 3) Maher migrates vnic diagnostic counters reporting from debugfs to a dedicated devlink health reporter Maher Says: =========== net/mlx5: Expose vnic diagnostic counters using devlink Currently, vnic diagnostic counters are exposed through the following debugfs: $ ls /sys/kernel/debug/mlx5/0000:08:00.0/esw/vf_0/vnic_diag/ cq_overrun quota_exceeded_command total_q_under_processor_handle invalid_command send_queue_priority_update_flow nic_receive_steering_discard The current design does not allow the hypervisor to view the diagnostic counters of its VFs, in case the VFs get bound to a VM. In other words, the counters are not exposed for representor interfaces. Furthermore, the debugfs design is inconvenient future-wise, in case more counters need to be reported by the driver in the future. As these counters pertain to vNIC health, it is more appropriate to utilize the devlink health reporter to expose them. Thus, this patchest includes the following changes: * Drop the current vnic diagnostic counters debugfs interface. * Add a vnic devlink health reporter for PFs/VFs core devices, which when diagnosed will dump vnic diagnostic counter values that are queried from FW. * Add a vnic devlink health reporter for the representor interface, which serves the same purpose listed in the previous point, in addition to allowing the hypervisor to view its VFs diagnostic counters, even when the VFs are bounded to external VMs. Example of devlink health reporter usage is: $devlink health diagnose pci/0000:08:00.0 reporter vnic vNIC env counters: total_error_queues: 0 send_queue_priority_update_flow: 0 comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0 invalid_command: 0 quota_exceeded_command: 0 nic_receive_steering_discard: 0 =========== 4) SW steering fixes and improvements Yevgeny Kliteynik Says: ======================= These short patch series are just small fixes / improvements for SW steering: - Patch 1: Fix dumping of legacy modify_hdr in debug dump to align to what is expected by parser - Patch 2: Have separate threshold for ICM sync per ICM type - Patch 3: Add more info to the steering debug dump - Linux version and device name - Patch 4: Keep track of number of buddies that are currently in use per domain per buddy type ======================= * tag 'mlx5-updates-2023-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Update op_mode to op_mod for port selection net/mlx5: E-Switch, Remove unused mlx5_esw_offloads_vport_metadata_set() net/mlx5: E-Switch, Remove redundant dev arg from mlx5_esw_vport_alloc() net/mlx5: Include linux/pci.h for pci_msix_can_alloc_dyn() net/mlx5e: RX, Hook NAPIs to page pools net/mlx5e: RX, Fix XDP_TX page release for legacy rq nonlinear case net/mlx5e: RX, Fix releasing page_pool pages twice for striding RQ net/mlx5e: Add vnic devlink health reporter to representors net/mlx5: Add vnic devlink health reporter to PFs/VFs Revert "net/mlx5: Expose vnic diagnostic counters for eswitch managed vports" Revert "net/mlx5: Expose steering dropped packets counter" net/mlx5: DR, Add memory statistics for domain object net/mlx5: DR, Add more info in domain dbg dump net/mlx5: DR, Calculate sync threshold of each pool according to its type net/mlx5: DR, Fix dumping of legacy modify_hdr in debug dump ==================== Link: https://lore.kernel.org/r/20230421013850.349646-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The main changes are: 1) Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward, from Florian Westphal. 2) Fix race between btf_put and btf_idr walk which caused a deadlock, from Alexei Starovoitov. 3) Second big batch to migrate test_verifier unit tests into test_progs for ease of readability and debugging, from Eduard Zingerman. 4) Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree, from Dave Marchevsky. 5) Migrate bpf_for(), bpf_for_each() and bpf_repeat() macros from BPF selftests into libbpf-provided bpf_helpers.h header and improve kfunc handling, from Andrii Nakryiko. 6) Support 64-bit pointers to kfuncs needed for archs like s390x, from Ilya Leoshkevich. 7) Support BPF progs under getsockopt with a NULL optval, from Stanislav Fomichev. 8) Improve verifier u32 scalar equality checking in order to enable LLVM transformations which earlier had to be disabled specifically for BPF backend, from Yonghong Song. 9) Extend bpftool's struct_ops object loading to support links, from Kui-Feng Lee. 10) Add xsk selftest follow-up fixes for hugepage allocated umem, from Magnus Karlsson. 11) Support BPF redirects from tc BPF to ifb devices, from Daniel Borkmann. 12) Add BPF support for integer type when accessing variable length arrays, from Feng Zhou. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (71 commits) selftests/bpf: verifier/value_ptr_arith converted to inline assembly selftests/bpf: verifier/value_illegal_alu converted to inline assembly selftests/bpf: verifier/unpriv converted to inline assembly selftests/bpf: verifier/subreg converted to inline assembly selftests/bpf: verifier/spin_lock converted to inline assembly selftests/bpf: verifier/sock converted to inline assembly selftests/bpf: verifier/search_pruning converted to inline assembly selftests/bpf: verifier/runtime_jit converted to inline assembly selftests/bpf: verifier/regalloc converted to inline assembly selftests/bpf: verifier/ref_tracking converted to inline assembly selftests/bpf: verifier/map_ptr_mixing converted to inline assembly selftests/bpf: verifier/map_in_map converted to inline assembly selftests/bpf: verifier/lwt converted to inline assembly selftests/bpf: verifier/loops1 converted to inline assembly selftests/bpf: verifier/jeq_infer_not_null converted to inline assembly selftests/bpf: verifier/direct_packet_access converted to inline assembly selftests/bpf: verifier/d_path converted to inline assembly selftests/bpf: verifier/ctx converted to inline assembly selftests/bpf: verifier/btf_ctx_access converted to inline assembly selftests/bpf: verifier/bpf_get_stack converted to inline assembly ... ==================== Link: https://lore.kernel.org/r/20230421211035.9111-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-04-21fs/proc: add Kthread flag to /proc/$pid/statusChunguang Wu
The command `ps -ef ` and `top -c` mark kernel thread by '[' and ']', but sometimes the result is not correct. The task->flags in /proc/$pid/stat is good, but we need remember the value of PF_KTHREAD is 0x00200000 and convert dec to hex. If we have no binary program and shell script which read /proc/$pid/stat, we can know it directly by `cat /proc/$pid/status`.
