When using "run_cmd <command> &", then "$!" refers to the PID of the subshell used to run <command>, not the command itself. Therefore nettest_pids actually doesn't contain the list of the nettest commands running in the background. So cleanup() can't kill them and the nettest processes run until completion (fortunately they have a 5s timeout). Fix this by defining a new command for running processes in the background, for which "$!" really refers to the PID of the command run. Also, double quote variables on the modified lines, to avoid shellcheck warnings. Fixes: ece1278a ("selftests: net: add ESP-in-UDP PMTU test") Signed-off-by:

The cleanup() function takes care of killing processes launched by the test functions. It relies on variables like ${tcpdump_pids} to get the relevant PIDs. But tests are run in their own subshell, so updated *_pids values are invisible to other shells. Therefore cleanup() never sees any process to kill: $ ./tools/testing/selftests/net/pmtu.sh -t pmtu_ipv4_exception TEST: ipv4: PMTU exceptions [ OK ] TEST: ipv4: PMTU exceptions - nexthop objects [ OK ] $ pgrep -af tcpdump 6084 tcpdump -s 0 -i veth_A-R1 -w pmtu_ipv4_exception_veth_A-R1.pcap 6085 tcpdump -s 0 -i veth_R1-A -w pmtu_ipv4_exception_veth_R1-A.pcap 6086 tcpdump -s 0 -i veth_R1-B -w pmtu_ipv4_exception_veth_R1-B.pcap 6087 tcpdump -s 0 -i veth_B-R1 -w pmtu_ipv4_exception_veth_B-R1.pcap 6088 tcpdump -s 0 -i veth_A-R2 -w pmtu_ipv4_exception_veth_A-R2.pcap 6089 tcpdump -s 0 -i veth_R2-A -w pmtu_ipv4_exception_veth_R2-A.pcap 6090 tcpdump -s 0 -i veth_R2-B -w pmtu_ipv4_exception_veth_R2-B.pcap 6091 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap 6228 tcpdump -s 0 -i veth_A-R1 -w pmtu_ipv4_exception_veth_A-R1.pcap 6229 tcpdump -s 0 -i veth_R1-A -w pmtu_ipv4_exception_veth_R1-A.pcap 6230 tcpdump -s 0 -i veth_R1-B -w pmtu_ipv4_exception_veth_R1-B.pcap 6231 tcpdump -s 0 -i veth_B-R1 -w pmtu_ipv4_exception_veth_B-R1.pcap 6232 tcpdump -s 0 -i veth_A-R2 -w pmtu_ipv4_exception_veth_A-R2.pcap 6233 tcpdump -s 0 -i veth_R2-A -w pmtu_ipv4_exception_veth_R2-A.pcap 6234 tcpdump -s 0 -i veth_R2-B -w pmtu_ipv4_exception_veth_R2-B.pcap 6235 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap Fix this by running cleanup() in the context of the test subshell. Now that each test cleans the environment after completion, there's no need for calling cleanup() again when the next test starts. So let's drop it from the setup() function. This is okay because cleanup() is also called when pmtu.sh starts, so even the first test starts in a clean environment. Also, use tcpdump's immediate mode. Otherwise it might not have time to process buffered packets, resulting in missing packets or even empty pcap files for short tests. Note: PAUSE_ON_FAIL is still evaluated before cleanup(), so one can still inspect the test environment upon failure when using -p.

When a bonded interface is destroyed, .ndo_change_mtu can be called during the tear-down process while the RTNL lock is held. This is a problem since the auxiliary driver linked to the LAN driver needs to be notified of the MTU change, and this requires grabbing a device_lock on the auxiliary_device's dev. Currently this is being attempted in the same execution context as the call to .ndo_change_mtu which is causing a dead-lock. Move the notification of the changed MTU to a separate execution context (watchdog service task) and eliminate the "before" notification.

The ice_vc_send_msg_to_vf function has logic to detect "failure" responses being sent to a VF. If a VF is sent more than ICE_DFLT_NUM_INVAL_MSGS_ALLOWED then the VF is marked as disabled. Almost identical logic also existed in the i40e driver. This logic was added to the ice driver in commit 1071a835 ("ice: Implement virtchnl commands for AVF support") which itself copied from the i40e implementation in commit 5c3c48ac ("i40e: implement virtual device interface"). Neither commit provides a proper explanation or justification of the check. In fact, later commits to i40e changed the logic to allow bypassing the check in some specific instances. The "logic" for this seems to be that error responses somehow indicate a malicious VF. This is not really true. The PF might be sending an error for any number of reasons such as lack of resources, etc. Additionally, this causes the PF to log an info message for every failed VF response which may confuse users, and can spam the kernel log. This behavior is not documented as part of any requirement for our products and other operating system drivers such as the FreeBSD implementation of our drivers do not include this type of check. In fact, the change from dev_err to dev_info in i40e commit 18b7af57 ("i40e: Lower some message levels") explains that these messages typically don't actually indicate a real issue. It is quite likely that a user who hits this in practice will be very confused as the VF will be disabled without an obvious way to recover. We already have robust malicious driver detection logic using actual hardware detection mechanisms that detect and prevent invalid device usage. Remove the logic since its not a documented requirement and the behavior is not intuitive. Fixes: 1071a835 ("ice: Implement virtchnl commands for AVF support") Signed-off-by:

The i40e_vc_send_msg_to_vf_ex (and its wrapper i40e_vc_send_msg_to_vf) function has logic to detect "failure" responses sent to the VF. If a VF is sent more than I40E_DEFAULT_NUM_INVALID_MSGS_ALLOWED, then the VF is marked as disabled. In either case, a dev_info message is printed stating that a VF opcode failed. This logic originates from the early implementation of VF support in commit 5c3c48ac ("i40e: implement virtual device interface"). That commit did not go far enough. The "logic" for this behavior seems to be that error responses somehow indicate a malicious VF. This is not really true. The PF might be sending an error for any number of reasons such as lacking resources, an unsupported operation, etc. This does not indicate a malicious VF. We already have a separate robust malicious VF detection which relies on hardware logic to detect and prevent a variety of behaviors. There is no justification for this behavior in the original implementation. In fact, a later commit 18b7af57 ("i40e: Lower some message levels") reduced the opcode failure message from a dev_err to a dev_info. In addition, recent commit 01cbf508 ("i40e: Fix to not show opcode msg on unsuccessful VF MAC change") changed the logic to allow quieting it for expected failures. That commit prevented this logic from kicking in for specific circumstances. This change did not go far enough. The behavior is not documented nor is it part of any requirement for our products. Other operating systems such as the FreeBSD implementation of our driver do not include this logic. It is clear this check does not make sense, and causes problems which led to ugly workarounds. Fix this by just removing the entire logic and the need for the i40e_vc_send_msg_to_vf_ex function.

To fix, it was added a new flag IAVF_FLAG_REINIT_MSIX_NEEDED used to trigger MSI-X reinit. New combined setting is fixed adopt after VF reset. This has been implemented by call reinit interrupt scheme during VF reset. Without this fix new combined setting has never been adopted.

According to Documentation/driver-api/usb/URB.rst when a device is unplugged usb_submit_urb() returns -ENODEV. This error code propagates all the way up to usbnet_read_cmd() and usbnet_write_cmd() calls inside the smsc95xx.c driver during Ethernet cable unplug, unbind or reboot. This causes the following errors to be shown on reboot, for example: ci_hdrc ci_hdrc.1: remove, state 1 usb usb2: USB disconnect, device number 1 usb 2-1: USB disconnect, device number 2 usb 2-1.1: USB disconnect, device number 3 smsc95xx 2-1.1:1.0 eth1: unregister 'smsc95xx' usb-ci_hdrc.1-1.1, smsc95xx USB 2.0 Ethernet smsc95xx 2-1.1:1.0 eth1: Failed to read reg index 0x00000114: -19 smsc95xx 2-1.1:1.0 eth1: Error reading MII_ACCESS smsc95xx 2-1.1:1.0 eth1: __smsc95xx_mdio_read: MII is busy smsc95xx 2-1.1:1.0 eth1: Failed to read reg index 0x00000114: -19 smsc95xx 2-1.1:1.0 eth1: Error reading MII_ACCESS smsc95xx 2-1.1:1.0 eth1: __smsc95xx_mdio_read: MII is busy smsc95xx 2-1.1:1.0 eth1: hardware isn't capable of remote wakeup usb 2-1.4: USB disconnect, device number 4 ci_hdrc ci_hdrc.1: USB bus 2 deregistered ci_hdrc ci_hdrc.0: remove, state 4 usb usb1: USB disconnect, device number 1 ci_hdrc ci_hdrc.0: USB bus 1 deregistered imx2-wdt 30280000.watchdog: Device shutdown: Expect reboot! reboot: Restarting system Ignore the -ENODEV errors inside __smsc95xx_mdio_read() and __smsc95xx_phy_wait_not_busy() and do not print error messages when -ENODEV is returned.

The esp tunnel GSO handlers use skb_mac_gso_segment to push the inner packet to the segmentation handlers. However, skb_mac_gso_segment takes the Ethernet Protocol ID from 'skb->protocol' which is wrong for inter address family tunnels. We fix this by introducing a new skb_eth_gso_segment function. This function can be used if it is necessary to pass the Ethernet Protocol ID directly to the segmentation handler. First users of this function will be the esp4 and esp6 tunnel segmentation handlers. Fixes: c35fe410 ("xfrm: Add mode handlers for IPsec on layer 2") Signed-off-by:
