We originally deprecated this a few releases ago, but I've since had two people report that it's being used. Which isn't the biggest deal, obviously this is why we out in the deprecation notice in the first place, but it also means that we should just kill this warning again and abandon the deprecation plans.

2023-06-02fork, vhost: Use CLONE_THREAD to fix freezer/ps regressionMike Christie11-77/+89
When switching from kthreads to vhost_tasks two bugs were added: 1. The vhost worker tasks's now show up as processes so scripts doing ps or ps a would not incorrectly detect the vhost task as another process. 2. kthreads disabled freeze by setting PF_NOFREEZE, but vhost tasks's didn't disable or add support for them. To fix both bugs, this switches the vhost task to be thread in the process that does the VHOST_SET_OWNER ioctl, and has vhost_worker call get_signal to support SIGKILL/SIGSTOP and freeze signals. Note that SIGKILL/STOP support is required because CLONE_THREAD requires CLONE_SIGHAND which requires those 2 signals to be supported. This is a modified version of the patch written by Mike Christie <michael.christie@oracle.com> which was a modified version of patch originally written by Linus. Much of what depended upon PF_IO_WORKER now depends on PF_USER_WORKER. Including ignoring signals, setting up the register state, and having get_signal return instead of calling do_group_exit. Tidied up the vhost_task abstraction so that the definition of vhost_task only needs to be visible inside of vhost_task.c. Making it easier to review the code and tell what needs to be done where. As part of this the main loop has been moved from vhost_worker into vhost_task_fn. vhost_worker now returns true if work was done. The main loop has been updated to call get_signal which handles SIGSTOP, freezing, and collects the message that tells the thread to exit as part of process exit. This collection clears __fatal_signal_pending. This collection is not guaranteed to clear signal_pending() so clear that explicitly so the schedule() sleeps. For now the vhost thread continues to exist and run work until the last file descriptor is closed and the release function is called as part of freeing struct file. To avoid hangs in the coredump rendezvous and when killing threads in a multi-threaded exec. The coredump code and de_thread have been modified to ignore vhost threads. Remvoing the special case for exec appears to require teaching vhost_dev_flush how to directly complete transactions in case the vhost thread is no longer running. Removing the special case for coredump rendezvous requires either the above fix needed for exec or moving the coredump rendezvous into get_signal.

The Linux Kernel currently only requires make v3.82 while the grouped target functionality requires make v4.3. Removed the grouped target introduced in 4ce1f694eb5d ("selinux: ensure av_permissions.h is built when needed") as well as the multiple header file targets in the make rule.

2023-06-01riscv: perf: Fix callchain parse error with kernel tracepoint eventsIsm Hong1-0/+7
For RISC-V, when tracing with tracepoint events, the IP and status are set to 0, preventing the perf code parsing the callchain and resolving the symbols correctly. ./ply 'tracepoint:kmem/kmem_cache_alloc { @[stack]=count(); }' @: { <STACKID4294967282> }: 1 The fix is to implement perf_arch_fetch_caller_regs for riscv, which fills several necessary registers used for callchain unwinding, including epc, sp, s0 and status.

2023-06-01mptcp: fix active subflow finalizationPaolo Abeni1-9/+14
Active subflow are inserted into the connection list at creation time. When the MPJ handshake completes successfully, a new subflow creation netlink event is generated correctly, but the current code wrongly avoid initializing a couple of subflow data. The above will cause misbehavior on a few exceptional events: unneeded mptcp-level retransmission on msk-level sequence wrap-around and infinite mapping fallback even when a MPJ socket is present. Address the issue factoring out the needed initialization in a new helper and invoking the latter from __mptcp_finish_join() time for passive subflow and from mptcp_finish_join() for active ones.

2023-06-01mptcp: consolidate passive msk socket initializationPaolo Abeni3-38/+33
When the msk socket is cloned at MPC handshake time, a few fields are initialized in a racy way outside mptcp_sk_clone() and the msk socket lock. The above is due historical reasons: before commit a88d0092b24b ("mptcp: simplify subflow_syn_recv_sock()") as the first subflow socket carrying all the needed date was not available yet at msk creation time We can now refactor the code moving the missing initialization bit under the socket lock, removing the init race and avoiding some code duplication. This will also simplify the next patch, as all msk->first write access are now under the msk socket lock.

2023-06-01mptcp: add annotations around msk->subflow accessesPaolo Abeni2-9/+15
The MPTCP can access the first subflow socket in a few spots outside the socket lock scope. That is actually safe, as MPTCP will delete the socket itself only after the msk sock close(). Still the such accesses causes a few KCSAN splats, as reported by Christoph. Silence the harmless warning adding a few annotation around the relevant accesses.

2023-06-01mptcp: fix connect timeout handlingPaolo Abeni2-23/+7
Ondrej reported a functional issue WRT timeout handling on connect with a nice reproducer. The problem is that the current mptcp connect waits for both the MPTCP socket level timeout, and the first subflow socket timeout. The latter is not influenced/touched by the exposed setsockopt(). Overall the above makes the SO_SNDTIMEO a no-op on connect. Since mptcp_connect is invoked via inet_stream_connect and the latter properly handle the MPTCP level timeout, we can address the issue making the nested subflow level connect always unblocking. This also allow simplifying a bit the code, dropping an ugly hack to handle the fastopen and custom proto_ops connect. The issues predates the blamed commit below, but the current resolution requires the infrastructure introduced there.

2023-06-01ice: recycle/free all of the fragments from multi-buffer frameMaciej Fijalkowski1-1/+1
The ice driver caches next_to_clean value at the beginning of ice_clean_rx_irq() in order to remember the first buffer that has to be freed/recycled after main Rx processing loop. The end boundary is indicated by first descriptor of frame that Rx processing loop has ended its duties. Note that if mentioned loop ended in the middle of gathering multi-buffer frame, next_to_clean would be pointing to the descriptor in the middle of the frame BUT freeing/recycling stage will stop at the first descriptor. This means that next iteration of ice_clean_rx_irq() will miss the (first_desc, next_to_clean - 1) entries.

And for zoned devices, we call fill_writer_pointer_gap() to make sure all the writes into the zoned device is sequential, even if there may be some gaps between the writes. However we have several different bugs all related to zoned dev-replace: - We are using ZONE_APPEND operation for metadata style write back For zoned devices, btrfs has two ways to write data: * ZONE_APPEND for data This allows higher queue depth, but will not be able to know where the write would land. Thus needs to grab the real on-disk physical location in it's endio. * WRITE for metadata This requires single queue depth (new writes can only be submitted after previous one finished), and all writes must be sequential. For scrub, we go single queue depth, but still goes with ZONE_APPEND, which requires btrfs_bio::inode being populated. This is the cause of that crash. - No correct tracing of write_pointer After a write finished, we should forward sctx->write_pointer, or fill_writer_pointer_gap() would not work properly and cause more than necessary zero out, and fill the whole zone prematurely. - Incorrect physical bytenr passed to fill_writer_pointer_gap() In scrub_write_sectors(), one call site passes logical address, which is completely wrong. The other call site passes physical address of current sector, but we should pass the physical address of the btrfs_bio we're submitting. This is the cause of the -EIO errors. [FIX] - Do not use ZONE_APPEND for btrfs_submit_repair_write(). - Manually forward sctx->write_pointer after successful writeback - Use the physical address of the to-be-submitted btrfs_bio for fill_writer_pointer_gap() Now zoned device replace would work as expected.
