If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER handler cannot perform VF register successfully as the register call is received before netvsc_probe is finished. This is because we register register_netdevice_notifier() very early( even before vmbus_driver_register()). To fix this, we try to register each such matching VF( if it is visible as a netdevice) at the end of netvsc_probe.

For XDP_TX action xdp_buff is converted to xdp_frame. The conversion is done by xdp_convert_buff_to_frame(). The memory type of the resulting xdp_frame depends on the memory type of the xdp_buff. For page pool based xdp_buff it produces xdp_frame with memory type MEM_TYPE_PAGE_POOL. For zero copy XSK pool based xdp_buff it produces xdp_frame with memory type MEM_TYPE_PAGE_ORDER0. tsnep_xdp_xmit_back() is not prepared for that and uses always the page pool buffer type TSNEP_TX_TYPE_XDP_TX. This leads to invalid mappings and the transmission of undefined data. Improve tsnep_xdp_xmit_back() to use the generic buffer type TSNEP_TX_TYPE_XDP_NDO for zero copy XDP_TX.

Using hard-coded constant timeout to wait for some expected event is deemed to fail sooner or later, especially in slow env.

The pmtu.sh test uses a few TCP listener in a problematic way: It hard-codes a constant timeout to wait for the listener starting-up in background. That introduces unneeded latency and on very slow and busy host it can fail. Additionally the test starts again the same listener in the same namespace on the same port, just after the previous connection completed. Fast host can attempt starting the new server before the old one really closed the socket. Address the issues using the wait_local_port_listen helper and explicitly waiting for the background listener process exit.

Pull parisc architecture fixes from Helge Deller: "The current exception handler, which helps on kernel accesses to userspace, may exhibit data corruption. The problem is that it is not guaranteed that the compiler will use the processor register we specified in the source code, but may choose another register which then will lead to silent register- and data corruption. To fix this issue we now use another strategy to help the exception handler to always find and set the error code into the correct CPU register. The other fixes are small: fixing CPU hotplug bringup, fix the page alignment of the RO_DATA section, added a check for the calculated cache stride and fix possible hangups when printing longer output at bootup when running on serial console. Most of the patches are tagged for stable series. - Fix random data corruption triggered by exception handler - Fix crash when setting up BTLB at CPU bringup - Prevent hung tasks when printing inventory on serial console - Make RO_DATA page aligned in vmlinux.lds.S - Add check for valid cache stride size" * tag 'parisc-for-6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: BTLB: Fix crash when setting up BTLB at CPU bringup parisc: Fix random data corruption from exception handler parisc: Drop unneeded semicolon in parse_tree_node() parisc: Prevent hung tasks when printing inventory on serial console parisc: Check for valid stride size for cache flushes parisc: Make RO_DATA page aligned in vmlinux.lds.S

In the arm random config file, kconfig option 'CONFIG_AEABI' is disabled which results in adding the compiler flag '-mabi=apcs-gnu'. This causes the compiler to add padding in virtchnl2_ptype structure to align it to 8 bytes, resulting in the following size check failure: include/linux/build_bug.h:78:41: error: static assertion failed: "(6) == sizeof(struct virtchnl2_ptype)" 78 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg) | ^~~~~~~~~~~~~~ include/linux/build_bug.h:77:34: note: in expansion of macro '__static_assert' 77 | #define static_assert(expr, ...) __static_assert(expr, ##__VA_ARGS__, #expr) | ^~~~~~~~~~~~~~~ drivers/net/ethernet/intel/idpf/virtchnl2.h:26:9: note: in expansion of macro 'static_assert' 26 | static_assert((n) == sizeof(struct X)) | ^~~~~~~~~~~~~ drivers/net/ethernet/intel/idpf/virtchnl2.h:982:1: note: in expansion of macro 'VIRTCHNL2_CHECK_STRUCT_LEN' 982 | VIRTCHNL2_CHECK_STRUCT_LEN(6, virtchnl2_ptype); | ^~~~~~~~~~~~~~~~~~~~~~~~~~ Avoid the compiler padding by using "__packed" structure attribute for the virtchnl2_ptype struct.

Matthieu Baerts says: ==================== mptcp: fixes for recent issues reported by CI's This series of 9 patches fixes issues mostly identified by CI's not managed by the MPTCP maintainers. Thank you Linero (LKFT) and Netdev maintainers (NIPA) for running our kunit and selftests tests! For the first patch, it took a bit of time to identify the root cause. Some MPTCP Join selftest subtests have been "flaky", mostly in slow environments. It appears to be due to the use of a TCP-specific helper on an MPTCP socket. A fix for kernels >= v5.15. Patches 2 to 4 add missing kernel config to support NetFilter tables needed for IPTables commands. These kconfigs are usually enabled in default configurations, but apparently not for all architectures. Patches 2 and 3 can be backported up to v5.11 and the 4th one up to v5.19. Patch 5 increases the time limit for MPTCP selftests. It appears that many CI's execute tests in a VM without acceleration supports, e.g. QEmu without KVM. As a result, the tests take longer. Plus, there are more and more tests. This patch modifies the timeout added in v5.18. Patch 6 reduces the maximum rate and delay of the different links in some Simult Flows selftest subtests. The goal is to let slow VMs reach the maximum speed. The original rate was introduced in v5.11. Patch 7 lets CI changing the prefix of the subtests titles, to be able to run the same selftest multiple times with different parameters. With different titles, tests will be considered as different and not override previous results as it is the case with some CI envs. Subtests have been introduced in v6.6. Patch 8 and 9 make some MPTCP Join selftest subtests quicker by stopping the transfer when the expected events have been seen. Patch 8 can be backported up to v6.5. Signed-off-by:

Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds on slow environments. While at it, use 'mptcp_lib_kill_wait()' helper everywhere, instead of on a specific one with 'kill_tests_wait()'.

There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds in slow environments.

If a CI executes the same selftest multiple times with different options, all results from the same subtests will have the same title, which confuse the CI. With the same title printed in TAP, the tests are considered as the same ones. Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST env var, and have a different title. While at it, use 'basename' to remove the suffix as well instead of using an extra 'sed'.

When running the simult_flow selftest in slow environments -- e.g. QEmu without KVM support --, the results can be unstable. This selftest checks if the aggregated bandwidth is (almost) fully used as expected. To help improving the stability while still keeping the same validation in place, the BW and the delay are reduced to lower the pressure on the CPU.

On very slow environments -- e.g. when QEmu is used without KVM --, mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the default timeout by 50% as it seems normal to take that long on some environments. When a debug kernel config is used, this selftest will take even longer, but that's certainly not a common test env to consider for the timeout. The Fixes tag that has been picked here is there simply to help having this patch backported to older stable versions. It is difficult to point to the exact commit that made some env reaching the timeout from time to time.
