Check the state of the rxrpc call backing an afs call in each iteration of the call wait loop in case the rxrpc call has already been terminated at the rxrpc layer. Interrupt the wait loop and mark the afs call as complete if the rxrpc layer call is complete. There were cases where rxrpc errors were not passed up to afs, which could result in this loop waiting forever for an afs call to transition to AFS_CALL_COMPLETE while the rx call was already complete.

When an ICMP or ICMPV6 error is received, the error will be attached to the socket (sk_err) and the report function will get called. Clear any pending error here by calling sock_error(). This would cause the following attempt to use the socket to fail with the error code stored by the ICMP error, resulting in unexpected errors with various side effects depending on the context.

The err2 error return path calls qede_ptp_disable that cleans up on an error and frees ptp. After this, the free'd ptp is dereferenced when ptp->clock is set to NULL and the code falls-through to error path err1 that frees ptp again. Fix this by calling qede_ptp_disable and exiting via an error return path that does not set ptp->clock or kfree ptp.

After commit e21db6f6 ("tcp: track total bytes delivered with ECN CE marks") core TCP stack does a very good job tracking ECN signals. The "sender's best estimate of CE information" Yuchung mentioned in his patch is indeed the best we can do. DCTCP can use tp->delivered_ce and tp->delivered to not duplicate the logic, and use the existing best estimate. This solves some problems, since current DCTCP logic does not deal with losses and/or GRO or ack aggregation very well. This also removes a dubious use of inet_csk(sk)->icsk_ack.rcv_mss (this should have been tp->mss_cache), and a 64 bit divide. Finally, we can see that the DCTCP logic, calling dctcp_update_alpha() for every ACK could be done differently, calling it only once per RTT. Signed-off-by:

A couple of tests are verifying a route has been removed. The helper expects the prefix as the first part of the expected output. When checking that a route has been deleted the prefix is empty leading to an invalid ip command: $ ip ro ls match Command line is not complete. Try option "help" Fix by moving the comparison of expected output and output to a new function that is used by both check_route and check_route6. Use the new helper for the 2 checks on route removal. Also, remove the reset of 'set -x' in route_setup which overrides the user managed setting. Fixes: d69faad7 ("selftests: fib_tests: Add prefix route tests with metric") Signed-off-by:

The thunderx driver splits frames bigger than 1530 bytes to multiple pages, making impossible to run an eBPF program on it. This leads to a maximum MTU of 1508 if QinQ is in use. The thunderx driver forbids to load an eBPF program if the MTU is higher than 1500 bytes. Raise the limit to 1508 so it is possible to use L2 protocols which need some more headroom.

The FLUSH command is used to empty the pnet table. No return code is expected from the command. Commit a9d8b0b1e3d6 added namespace support for the pnet table and changed the FLUSH command processing to call smc_pnet_remove_by_pnetid() to remove the pnet entries. This function returns -ENOENT when no entry was deleted, which is now the return code of the FLUSH command. As a result the FLUSH command will return an error when the pnet table is already empty. Restore the expected behavior and let FLUSH always return 0. Fixes: a9d8b0b1e3d6 ("net/smc: add pnet table namespace support") Signed-off-by: -

fcntl(fd, F_SETOWN, getpid()) selects the recipient of SIGURG signals that are delivered when out-of-band data arrives on socket fd. If an SMC socket program makes use of such an fcntl() call, it fails in case of fallback to TCP-mode. In case of fallback the traffic is processed with the internal TCP socket. Propagating field "file" from the SMC socket to the internal TCP socket fixes the issue. Reviewed-by:

When the clcsock is already released using sock_release() and a pending smc_listen_work accesses the clcsock than that will fail. Solve this by canceling and waiting for the work to complete first. Because the work holds the sock_lock it must make sure that the lock is not hold before the new helper smc_clcsock_release() is invoked. And before the smc_listen_work starts working check if the parent listen socket is still valid, otherwise stop the work early. Signed-off-by:

When a netdev appears through hot plug then gets enslaved by a failover master that is already up and running, the slave will be opened right away after getting enslaved. Today there's a race that userspace (udev) may fail to rename the slave if the kernel (net_failover) opens the slave earlier than when the userspace rename happens. Unlike bond or team, the primary slave of failover can't be renamed by userspace ahead of time, since the kernel initiated auto-enslavement is unable to, or rather, is never meant to be synchronized with the rename request from userspace. As the failover slave interfaces are not designed to be operated directly by userspace apps: IP configuration, filter rules with regard to network traffic passing and etc., should all be done on master interface. In general, userspace apps only care about the name of master interface, while slave names are less important as long as admin users can see reliable names that may carry other information describing the netdev. For e.g., they can infer that "ens3nsby" is a standby slave of "ens3", while for a name like "eth0" they can't tell which master it belongs to. Historically the name of IFF_UP interface can't be changed because there might be admin script or management software that is already relying on such behavior and assumes that the slave name can't be changed once UP. But failover is special: with the in-kernel auto-enslavement mechanism, the userspace expectation for device enumeration and bring-up order is already broken. Previously initramfs and various userspace config tools were modified to bypass failover slaves because of auto-enslavement and duplicate MAC address. Similarly, in case that users care about seeing reliable slave name, the new type of failover slaves needs to be taken care of specifically in userspace anyway. It's less risky to lift up the rename restriction on failover slave which is already UP. Although it's possible this change may potentially break userspace component (most likely configuration scripts or management software) that assumes slave name can't be changed while UP, it's relatively a limited and controllable set among all userspace components, which can be fixed specifically to listen for the rename events on failover slaves. Userspace component interacting with slaves is expected to be changed to operate on failover master interface instead, as the failover slave is dynamic in nature which may come and go at any point. The goal is to make the role of failover slaves less relevant, and userspace components should only deal with failover master in the long run.

Jakub Kicinski authored
This reverts the first part of commit 4e485d06 ("strparser: Call skb_unclone conditionally"). To build a message with multiple fragments we need our own root of frag_list. We can't simply use the frag_list of orig_skb, because it will lead to linking all orig_skbs together creating very long frag chains, and causing stack overflow on kfree_skb() (which is called recursively on the frag_lists). BUG: stack guard page was hit at 00000000d40fad41 (stack is 0000000029dde9f4..000000008cce03d5) kernel stack overflow (double-fault): 0000 [#1] PREEMPT SMP RIP: 0010:free_one_page+0x2b/0x490 Call Trace: __free_pages_ok+0x143/0x2c0 skb_release_data+0x8e/0x140 ? skb_release_data+0xad/0x140 kfree_skb+0x32/0xb0 [...] skb_release_data+0xad/0x140 ? skb_release_data+0xad/0x140 kfree_skb+0x32/0xb0 skb_release_data+0xad/0x140 ? skb_release_data+0xad/0x140 kfree_skb+0x32/0xb0 skb_release_data+0xad/0x140 ? skb_release_data+0xad/0x140 kfree_skb+0x32/0xb0 skb_release_data+0xad/0x140 ? skb_release_data+0xad/0x140 kfree_skb+0x32/0xb0 skb_release_data+0xad/0x140 __kfree_skb+0xe/0x20 tcp_disconnect+0xd6/0x4d0 tcp_close+0xf4/0x430 ? tcp_check_oom+0xf0/0xf0 tls_sk_proto_close+0xe4/0x1e0 [tls] inet_release+0x36/0x60 __sock_release+0x37/0xa0 sock_close+0x11/0x20 __fput+0xa2/0x1d0 task_work_run+0x89/0xb0 exit_to_usermode_loop+0x9a/0xa0 do_syscall_64+0xc0/0xf0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Let's leave the second unclone conditional, as I'm not entirely sure what is its purpose :) Fixes: 4e485d06 ("strparser: Call skb_unclone conditionally") Signed-off-by:

David reports that tls triggers warnings related to sk->sk_forward_alloc not being zero at destruction time: WARNING: CPU: 5 PID: 6831 at net/core/stream.c:206 sk_stream_kill_queues+0x103/0x110 WARNING: CPU: 5 PID: 6831 at net/ipv4/af_inet.c:160 inet_sock_destruct+0x15b/0x170 When sender fills up the write buffer and dies from SIGPIPE. This is due to the device implementation not cleaning up the partially_sent_record. This is because commit a42055e8 ("net/tls: Add support for async encryption of records for performance") moved the partial record cleanup to the SW-only path.
