2024-02-28tools: ynl-gen: remove unused parse codeJakub Kicinski
Commit f2ba1e5e2208 ("tools: ynl-gen: stop generating common notification handlers") removed the last caller of the parse_cb_run() helper. We no longer need to export ynl_cb_array.

2024-02-28tools: ynl: make yarg the first member of struct ynl_dump_stateJakub Kicinski
All YNL parsing code expects a pointer to struct ynl_parse_arg AKA yarg. For dump was pass in struct ynl_dump_state, which works fine, because struct ynl_dump_state and struct ynl_parse_arg have identical layout for the members that matter.. but it's a bit hacky.

2024-02-28tools: ynl: create local attribute helpersJakub Kicinski
Don't use mnl attr helpers, we're trying to remove the libmnl dependency. Create both signed and unsigned helpers, libmnl had unsigned helpers, so code generator no longer needs the mnl_type() hack. The new helpers are written from first principles, but are hopefully not too buggy.

2024-02-28tools: ynl: give up on libmnl for auto-intsJakub Kicinski
The temporary auto-int helpers are not really correct. We can't treat signed and unsigned ints the same when determining whether we need full 8B. I realized this before sending the patch to add support in libmnl. Unfortunately, that patch has not been merged, so time to fix our local helpers. Use the mnl* name for now, subsequent patches will address that.

2024-02-27selftests: netdevsim: be less selective for FW for the devlink testJakub Kicinski
Commit 6151ff9c7521 ("selftests: netdevsim: use suitable existing dummy file for flash test") introduced a nice trick to the devlink flashing test. Instead of user having to create a file under /lib/firmware we just pick the first one that already exists. Sadly, in AWS Linux there are no files directly under /lib/firmware, only in subdirectories. Don't limit the search to -maxdepth 1. We can use the %P print format to get the correct path for files inside subdirectories: $ find /lib/firmware -type f -printf '%P\n' | head -1 intel-ucode/06-1a-05 The full path is /lib/firmware/intel-ucode/06-1a-05 This works in GNU find, busybox doesn't have printf at all, so we're not making it worse.

2024-02-26selftests: mptcp: lib: catch duplicated subtest entriesMatthieu Baerts (NGI0)
It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated name. When adding a new subtest entry, an error message is printed in case of duplicated entries. If there were duplicated entries and if all features were expected to work, the script exits with an error at the end, after having printed all subtests in the TAP format. Thanks to that, the MPTCP CI will catch such issues early.

During decoding of messages coming from kernel, attribute values are converted to enum names in case the attribute type is enum of bitfield32.

2024-02-22net: mctp: tests: Test that outgoing skbs have flow data populatedJeremy Kerr
When CONFIG_MCTP_FLOWS is enabled, outgoing skbs should have their SKB_EXT_MCTP extension set for drivers to consume. Add two tests for local-to-output routing that check for the flow extensions: one for the simple single-packet case, and one for fragmentation. We now make MCTP_TEST select MCTP_FLOWS, so we always get coverage of these flow tests. The tests are skippable if MCTP_FLOWS is (otherwise) disabled, but that would need manual config tweaking.

ioam6_parser uses a packet socket. After the fix to prevent writing to cloned skb's, the receiver does not see its IOAM data anymore, which makes input/forward ioam-selftests to fail. As a workaround, ioam6_parser now uses an IPv6 raw socket and leverages ancillary data to get hop-by-hop options. As a consequence, the hook is "after" the IOAM data insertion by the receiver and all tests are working again.

This patch is to add a selftest that can trigger the bug. I can trigger the UAF everytime in my qemu setup with KASAN.

2024-02-19selftests: bonding: set active slave to primary eth1 specificallyHangbin Liu
In bond priority testing, we set the primary interface to eth1 and add eth0,1,2 to bond in serial. This is OK in normal times. But when in debug kernel, the bridge port that eth0,1,2 connected would start slowly (enter blocking, forwarding state), which caused the primary interface down for a while after enslaving and active slave changed. Here is a test log from Jakub's debug test[1].

It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated names. Some subtests from the userspace_pm selftest had the same names. That's because different subflows are created (and deleted) between the same pair of IP addresses. Simply adding the destination port in the name is then enough to have different names, because the destination port is always different. Note that adding such info takes a bit more space, so we need to increase a bit the width to print the name, simply to keep all the '[ OK ]' aligned as before.

2024-02-16net/sched: act_mirred: use the backlog for mirred ingressJakub Kicinski
The test Davide added in commit ca22da2fbd69 ("act_mirred: use the backlog for nested calls to mirred ingress") hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv -> tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress -> ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround does not seem to address the issue.

2024-02-15selftest/bpf: Test the read of vsyscall page under x86-64Hou Tao
Under x86-64, when using bpf_probe_read_kernel{_str}() or bpf_probe_read{_str}() to read vsyscall page, the read may trigger oops, so add one test case to ensure that the problem is fixed. Beside those four bpf helpers mentioned above, testing the read of vsyscall page by using bpf_probe_read_user{_str} and bpf_copy_from_user{_task}() as well. The test case passes the address of vsyscall page to these six helpers and checks whether the returned values are expected: 1) For bpf_probe_read_kernel{_str}()/bpf_probe_read{_str}(), the expected return value is -ERANGE as shown below: bpf_probe_read_kernel_common copy_from_kernel_nofault // false, return -ERANGE copy_from_kernel_nofault_allowed 2) For bpf_probe_read_user{_str}(), the expected return value is -EFAULT as show below: bpf_probe_read_user_common copy_from_user_nofault // false, return -EFAULT __access_ok 3) For bpf_copy_from_user(), the expected return value is -EFAULT: // return -EFAULT bpf_copy_from_user copy_from_user _copy_from_user // return false access_ok 4) For bpf_copy_from_user_task(), the expected return value is -EFAULT: // return -EFAULT bpf_copy_from_user_task access_process_vm // return 0 vma_lookup() // return 0 expand_stack() The occurrence of oops depends on the availability of CPU SMAP [1] feature and there are three possible configurations of vsyscall page in the boot cmd-line: vsyscall={xonly|none|emulate}, so there are a total of six possible combinations. Under all these combinations, the test case runs successfully.
