While implementing support for in-kernel decompression in kmod, finit_module() was returning a very suspicious value: finit_module(3, "", MODULE_INIT_COMPRESSED_FILE) = 18446744072717407296 It turns out the check for module_get_next_page() failing is wrong, and hence the decompression was not really taking place. Invert the condition to fix it.

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 4ce1f694 ("selinux: ensure av_permissions.h is built when needed") as well as the multiple header file targets in the make rule. This effectively reverts the problem commit. We will revisit this change when make >= 4.3 is required by the rest of the kernel.

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.

The first subflow socket is accessed outside the msk socket lock by mptcp_subflow_fail(), we need to annotate each write access with WRITE_ONCE, but a few spots still lacks it. Fixes: 76a13b31 ("mptcp: invoke MP_FAIL response when needed") Reviewed-by:

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 a88d0092 ("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. Fixes: 0397c6d8 ("mptcp: keep unaccepted MPC subflow into join list") Reviewed-by:

Paolo Abeni authored
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.

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. Fixes: 54f1944e ("mptcp: factor out mptcp_connect()") Reported-by:

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.

marvell_nfc_setup_interface() uses the frequency retrieved from the clock associated with the nand interface to determine the timings that will be used. By changing the NAND frequency select without reflecting this in the clock configuration this means that the timings calculated don't correctly meet the requirements of the NAND chip.

A switch held in reset by default needs to wait longer until we can reliably detect it. An issue was observed when testing on the Marvell 88E6393X (Link Street). The driver failed to detect the switch on some upstarts. Increasing the wait time after reset deactivation solves this issue. The updated wait time is now also the same as the wait time in the mv88e6xxx_hardware_reset function. Fixes: 7b75e49d ("net: dsa: mv88e6xxx: wait after reset deactivation") Signed-off-by:

Zero-length and one-element arrays are deprecated, and we are moving towards adopting C99 flexible-array members, instead.

In this patch, we mainly try to handle sending a compressed ack correctly if it's deferred. Here are more details in the old logic: When sack compression is triggered in the tcp_compressed_ack_kick(), if the sock is owned by user, it will set TCP_DELACK_TIMER_DEFERRED and then defer to the release cb phrase. Later once user releases the sock, tcp_delack_timer_handler() should send a ack as expected, which, however, cannot happen due to lack of ICSK_ACK_TIMER flag. Therefore, the receiver would not sent an ack until the sender's retransmission timeout. It definitely increases unnecessary latency. Fixes: 5d9f4262 ("tcp: add SACK compression") Suggested-by:

If we send two TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets and their total size is 252 bytes(key->enc_opts.len = 252) then key->enc_opts.len = opt->length = data_len / 4 = 0 when the third TCA_FLOWER_KEY_ENC_OPTS_GENEVE packet enters fl_set_geneve_opt. This bypasses the next bounds check and results in an out-of-bounds. Fixes: 0a6e7778 ("net/sched: allow flower to match tunnel options") Signed-off-by:

Failure ladders weren't exactly unwinding what the function had done up to that point; most seriously, when we encountered an already offloaded rule, the failure path tried to remove the new rule from the hashtable, which would in fact remove the already-present 'old' rule (since it has the same key) from the table, and leak its resources.
