Commit 1a7d0890 ("kprobe/ftrace: bail out if ftrace was killed") introduced a bad K&R function definition, which we haven't accepted in a long long time. Gcc seems to let it slide, but clang notices with the appropriate error: kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all > 1140 | void kprobe_ftrace_kill() | ^ | void but this commit was apparently never in linux-next before it was sent upstream, so it didn't get the appropriate build test coverage.

Pull tracing tool updates from Steven Rostedt: "Specific for timerlat: - Improve the output of timerlat top by adding a missing \n, and by avoiding printing color-formatting characters where they are translated to regular characters. - Improve timerlat auto-analysis output by replacing '\t' with spaces to avoid copy-and-paste issues when reporting problems. - Make the user-space (-u) option the default, as it is the most complete test. Add a -k option to use the in-kernel workload. - On timerlat top and hist, add a summary with the overall results. For instance, the minimum value for all CPUs, the overall average and the maximum value from all CPUs. - timerlat hist was printing initial values (i.e., 0 as max, and ~0 as min) if the trace stopped before the first Ret-User event. This problem was fixed by printing the " - " no value string to the output if that was the case. For all RTLA tools: - Add a --warm-up <seconds> option, allowing the workload to run for <seconds> before starting to collect results. - Add a --trace-buffer-size option, allowing the user to set the tracing buffer size for -t option. This option is mainly useful for reducing the trace file. Now rtla depends on libtracefs >= 1.6. - Fix the -t [trace_file] parsing, now it does not require the '=' before the option parameter, and better handles the multiple ways a user can pass the trace_file.txt" * tag 'trace-tools-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: rtla: Documentation: Fix -t, --trace rtla: Fix -t\--trace[=file] rtla/timerlat: Fix histogram report when a cpu count is 0 rtla: Add --trace-buffer-size option rtla/timerlat: Make user-space threads the default rtla: Add the --warm-up option rtla/timerlat: Add a summary for hist mode rtla/timerlat: Add a summary for top mode rtla/timerlat: Use pretty formatting only on interactive tty rtla/auto-analysis: Replace \t with spaces rtla/timerlat: Simplify "no value" printing on top

Merge tag 'trace-user-events-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing user-event updates from Steven Rostedt: - Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored. But the parsing expected at least one space to be there (which was incorrect). Fix the reading of the string to handle fields separated by semicolons but no space between them. This does extend the API sightly as now "field;field" will now be parsed and not cause an error. But it should not cause any regressions as no logic should expect it to fail. Note, that the logic that parses the event fields to create the trace_event works with no spaces after the semi-colon. It is the logic that tests against existing events that is inconsistent. This causes registering an event without using spaces to succeed if it doesn't exist, but makes the same call that tries to register to the same event, but doesn't use spaces, fail. * tag 'trace-user-events-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: selftests/user_events: Add non-spacing separator check tracing/user_events: Fix non-spaced field matching

Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings. The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped" * tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Add cast to unsigned long addr passed to virt_to_page() ring-buffer: Have mmapped ring buffer keep track of missed events ring-buffer/selftest: Add ring-buffer mapping test Documentation: tracing: Add ring-buffer mapping tracing: Allow user-space mapping of the ring-buffer ring-buffer: Introducing ring-buffer mapping functions ring-buffer: Allocate sub-buffers with __GFP_COMP

Pull sysctl updates from Joel Granados: - Remove sentinel elements from ctl_table structs in kernel/* Removing sentinels in ctl_table arrays reduces the build time size and runtime memory consumed by ~64 bytes per array. Removals for net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline through their respective subsystems making the next release the most likely place where the final series that removes the check for proc_name == NULL will land. This adds to removals already in arch/, drivers/ and fs/. - Adjust ctl_table definitions and references to allow constification - Remove unused ctl_table function arguments - Move non-const elements from ctl_table to ctl_table_header - Make ctl_table pointers const in ctl_table_root structure Making the static ctl_table structs const will increase safety by keeping the pointers to proc_handler functions in .rodata.

See commit 90b9566a ("selftests: forwarding: add a test for local_termination.sh"). We don't want to hide the known gaps, but having a test which always fails prevents us from catching regressions.

Since commit a36e185e ("udp: Handle ICMP errors for tunnels with same destination port on both endpoints") UDP's handling of ICMP errors has allowed for UDP-encap tunnels to determine socket associations in scenarios where the UDP hash lookup could not. Subsequently, commit d26796ae ("udp: check udp sock encap_type in __udp_lib_err") subtly tweaked the approach such that UDP ICMP error handling would be skipped for any UDP socket which has encapsulation enabled. In the case of L2TP tunnel sockets using UDP-encap, this latter modification effectively broke ICMP error reporting for the L2TP control plane. To a degree this isn't catastrophic inasmuch as the L2TP control protocol defines a reliable transport on top of the underlying packet switching network which will eventually detect errors and time out. However, paying attention to the ICMP error reporting allows for more timely detection of errors in L2TP userspace, and aids in debugging connectivity issues. Reinstate ICMP error handling for UDP encap L2TP tunnels: * implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow the L2TP code to handle ICMP errors; * only implement error-handling for tunnels which have a managed socket: unmanaged tunnels using a kernel socket have no userspace to report errors back to; * flag the error on the socket, which allows for userspace to get an error such as -ECONNREFUSED back from sendmsg/recvmsg; * pass the error into ip[v6]_icmp_error() which allows for userspace to get extended error information via. MSG_ERRQUEUE.

"rmmod bonding" causes an oops ever since commit cc317ea3 ("bonding: remove redundant NULL check in debugfs function"). Here are the relevant functions being called: bonding_exit() bond_destroy_debugfs() debugfs_remove_recursive(bonding_debug_root); bonding_debug_root = NULL; <--------- SET TO NULL HERE bond_netlink_fini() rtnl_link_unregister() __rtnl_link_unregister() unregister_netdevice_many_notify() bond_uninit() bond_debug_unregister() (commit removed check for bonding_debug_root == NULL) debugfs_remove() simple_recursive_removal() down_write() -> OOPS However, reverting the bad commit does not solve the problem completely because the original code contains a race that could cause the same oops, although it was much less likely to be triggered unintentionally: CPU1 rmmod bonding bonding_exit() bond_destroy_debugfs() debugfs_remove_recursive(bonding_debug_root); CPU2 echo -bond0 > /sys/class/net/bonding_masters bond_uninit() bond_debug_unregister() if (!bonding_debug_root) CPU1 bonding_debug_root = NULL; So do NOT revert the bad commit (since the removed checks were racy anyway), and instead change the order of actions taken during module removal. The same oops can also happen if there is an error during module init, so apply the same fix there.

Problem ========= After commit 67f69513 ("ipv6: Move setting default metric for routes"), we noticed that the logic of assigning the default value of fc_metirc changed in the ioctl process. That is, when users use ioctl(fd, SIOCADDRT, rt) with a non-zero metric to add a route, then they may fail to delete a route with passing in a metric value of 0 to the kernel by ioctl(fd, SIOCDELRT, rt). But iproute can succeed in deleting it. As a reference, when using iproute tools by netlink to delete routes with a metric parameter equals 0, like the command as follows: ip -6 route del fe80::/64 via fe81::5054:ff:fe11:3451 dev eth0 metric 0 the user can still succeed in deleting the route entry with the smallest metric. Root Reason =========== After commit 67f69513 ("ipv6: Move setting default metric for routes"), When ioctl() pass in SIOCDELRT with a zero metric, rtmsg_to_fib6_config() will set a defalut value (1024) to cfg->fc_metric in kernel, and in ip6_route_del() and the line 4074 at net/ipv3/route.c, it will check by if (cfg->fc_metric && cfg->fc_metric != rt->fib6_metric) continue; and the condition is true and skip the later procedure (deleting route) because cfg->fc_metric != rt->fib6_metric. But before that commit, cfg->fc_metric is still zero there, so the condition is false and it will do the following procedure (deleting). Solution ======== In order to keep a consistent behaviour across netlink() and ioctl(), we should allow to delete a route with a metric value of 0. So we only do the default setting of fc_metric in route adding.
