Pedro Tammela says: ==================== net/sched: improve class lifetime handling Valis says[0]: ============ Three classifiers (cls_fw, cls_u32 and cls_route) always copy tcf_result struct into the new instance of the filter on update. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free. ============ Turns out these could have been spotted easily with proper warnings. Improve the current class lifetime with wrappers that check for overflow/underflow. While at it add an extack for when a class in use is deleted.

The 'filter_cnt' counter is used to control a Qdisc class lifetime. Each filter referecing this class by its id will eventually increment/decrement this counter in their respective 'add/update/delete' routines. As these operations are always serialized under rtnl lock, we don't need an atomic type like 'refcount_t'. It also means that we lose the overflow/underflow checks already present in refcount_t, which are valuable to hunt down bugs where the unsigned counter wraps around as it aids automated tools like syzkaller to scream in such situations. Wrap the open coded increment/decrement into helper functions and add overflow checks to the operations. Acked-by:

Matthieu Baerts says: ==================== mptcp: cleanup and improvements in the selftests This small series of 4 patches adds some improvements in MPTCP selftests: - Patch 1 reworks the detailed report of mptcp_join.sh selftest to better display what went well or wrong per test. - Patch 2 adds colours (if supported, forced and/or not disabled) in mptcp_join.sh selftest output to help spotting issues. - Patch 3 modifies an MPTCP selftest tool to interact with the path-manager via Netlink to always look for errors if any. This makes sure odd behaviours can be seen in the logs and errors can be caught later if needed. - Patch 4 removes stdout and stderr redirections to /dev/null when using pm_nl_ctl if no errors are expected in order to log odd behaviours. ==================== Link: https://lore.kernel.org/r/20230730-upstream-net-next-20230728-mptcp-selftests-misc-v1-0-7e9cc530a9cd@tessares.netSigned-off-by:

All pm_nl_ctl commands were muted. If there was an unexpected error with one of them, this was simply not visible in the logs, making the analysis very hard. It could also hide misuse of commands by mistake. Now the output is only muted when we do expect to have an error, e.g. when giving invalid arguments on purpose. Reviewed-by:

If a Netlink command for the MPTCP path-managers is not valid, it is important to check if there are errors. If yes, they need to be reported instead of being ignored and exiting without errors. Now if no replies are expected, an ACK from the kernelspace is asked by the userspace in order to always expect a reply. We can use the same buffer that is currently always >1024 bytes. Then we can check if there is an error (err->error), print it if any and report the error. After this modification, it is required to mute expected errors in mptcp_join.sh and pm_netlink.sh selftests: - when trying to add a bad endpoint, e.g. duplicated - when trying to set the two limits above the hard limit Reviewed-by:

Thanks to the parent commit, it is easy to change the output and add some colours to help spotting issues. The colours are not used if stdout is redirected or if NO_COLOR env var is set to 1 as specified in https://no-color.org. It is possible to force displaying the colours even if stdout is redirected by setting this env var: SELFTESTS_MPTCP_LIB_COLOR_FORCE=1 Acked-by:

This patch modifies how the detailed results are printed, mainly to improve what is displayed in case of issue: - Now the test name (title) is printed earlier, when starting the test if it is not intentionally skipped: by doing that, errors linked to a test will be printed after having written the test name and then avoid confusions. - Due to the previous item, it is required to add a new line after having printed the test name because in case of error with a command, it is better not to have the output in the middle of the screen. - Each check is printed on a dedicated line with aligned status (ok, skip, fail): it is easier to spot which one has failed, simpler to manage in the code not having to deal with alignment case by case and helpers can be used to uniform what is done. These helpers can also be useful later to do more actions depending on the results or change in one place what is printed. - Info messages have been reduced and aligned as well. And info messages about the creation of the default test files of 1 KB are no longer printed. Example: 001 no JOIN syn [ ok ] synack [ ok ] ack [ ok ] Or with a skip and a failure: 001 no JOIN syn [ ok ] synack [fail] got 42 JOIN[s] synack expected 0 Server ns stats (...) Client ns stats (...) ack [skip] Or with info: 104 Infinite map Test file (size 128 KB) for client Test file (size 128 KB) for server file received by server has inverted byte at 169 5 corrupted pkts syn [ ok ] synack [ ok ] While at it, verify_listener_events() now also print more info in case of failure and in pm_nl_check_endpoint(), the test is marked as failed instead of skipped if no ID has been given (internal selftest issue).

Martin KaFai Lau authored
During unregister_netdevice_many_notify(), the ordering of our concerned function calls is like this: unregister_netdevice_many_notify dev_shutdown qdisc_put clsact_destroy tcx_uninstall The syzbot reproducer triggered a case that the qdisc refcnt is not zero during dev_shutdown(). tcx_uninstall() will then WARN_ON_ONCE(tcx_entry(entry)->miniq_active) because the miniq is still active and the entry should not be freed. The latter assumed that qdisc destruction happens before tcx teardown. This fix is to avoid tcx_uninstall() doing tcx_entry_free() when the miniq is still alive and let the clsact_destroy() do the free later, so that we do not assume any specific ordering for either of them. If still active, tcx_uninstall() does clear the entry when flushing out the prog/link. clsact_destroy() will then notice the "!tcx_entry_is_active()" and then does the tcx_entry_free() eventually.

Commit df8fc4e9 ("kbuild: Enable -fstrict-flex-arrays=3") started applying strict rules to standard string functions. It does not work well with conventional socket code around each protocol- specific sockaddr_XXX struct, which is cast from sockaddr_storage and has a bigger size than fortified functions expect. See these commits: commit 06d4c8a8 ("af_unix: Fix fortify_panic() in unix_bind_bsd().") commit ecb4534b ("af_unix: Terminate sun_path when bind()ing pathname socket.") commit a0ade840 ("af_packet: Fix warning of fortified memcpy() in packet_getname().") We must cast the protocol-specific address back to sockaddr_storage to call such functions. However, in the case of getsockaddr(SO_PEERNAME), the rationale is a bit unclear as the buffer is defined by char[128] which is the same size as sockaddr_storage. Let's use sockaddr_storage explicitly. Signed-off-by:

Reduce the control transfer if all bytes of first or the last DWORD are written. The original method is to split the control transfer into three parts (the first DWORD, middle continuous data, and the last DWORD). However, they could be combined if whole bytes of the first DWORD or last DWORD are written. That is, the first DWORD or the last DWORD could be combined with the middle continuous data, if the byte_en is 0xff. Signed-off-by:
