Matthieu Baerts says: ==================== selftests: mptcp: skip tests not supported by old kernels (part 2) After a few years of increasing test coverage in the MPTCP selftests, we realised [1] the last version of the selftests is supposed to run on old kernels without issues. Supporting older versions is not that easy for this MPTCP case: these selftests are often validating the internals by checking packets that are exchanged, when some MIB counters are incremented after some actions, how connections are getting opened and closed in some cases, etc. In other words, it is not limited to the socket interface between the userspace and the kernelspace. In addition to that, the current MPTCP selftests run a lot of different sub-tests but the TAP13 protocol used in the selftests don't support sub-tests: one failure in sub-tests implies that the whole selftest is seen as failed at the end because sub-tests are not tracked. It is then important to skip sub-tests not supported by old kernels. To minimise the modifications and reduce the complexity to support old versions, the idea is to look at external signs and skip the whole selftests or just some sub-tests before starting them. This cannot be applied in all cases. This second part focuses on marking different sub-tests as skipped if some MPTCP features are not supported. A few techniques are used here: - Before starting some tests: - Check if a file (sysctl knob) is present: that's what patch 13/14 is doing for the userspace PM feature. - Check if a symbol is present in /proc/kallsyms: patch 1/14 adds some helpers in mptcp_lib.sh to ease its use. Then these helpers are used in patches 2, 3, 4, 10, 11 and 14/14. - Set a flag and get the status to check if a feature is supported: patch 8/14 is doing that with the 'fullmesh' flag. - After having launched the tests: - Retrieve the counters after a test and check if they are different than 0. Similar to the check with the flag, that's not ideal but in this case, the counters were already present before the introduction of MPTCP but they have been supported by MPTCP sockets only later. Patches 5 and 6/14 are using this technique. Before skipping tests, SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var value is checked: if it is set to 1, the test is marked as "failed" instead of "skipped". MPTCP public CI expects to have all features supported and it sets this env var to 1 to catch regressions in these new checks. Patches 7/14 and 9/14 are a bit different because they don't skip tests: - Patch 7/14 retrieves the default values instead of using hardcoded ones because these default values have been modified at some points. Then the comparisons are done with the default values. - patch 9/14 relaxes the expected returned size from MPTCP's getsockopt because the different structures gathering various info can get new fields and get bigger over time. We cannot expect that the userspace is using the same structure as the kernel. Patch 12/14 marks the test as "skipped" instead of "failed" if the "ip" tool is not available. In this second part, the "mptcp_join" selftest is not modified yet. This will come soon after in the third part with quite a few patches.

2023-06-10selftests: mptcp: userspace pm: skip PM listener events tests if unavailableMatthieu Baerts
Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the new listener events linked to the path-manager introduced by commit f8c9dfbd875b ("mptcp: add pm listener events"). It is possible to look for "mptcp_event_pm_listener" in kallsyms to know in advance if the kernel supports this feature and skip these sub-tests if the feature is not supported.

One of them is the MPTCP Userspace PM introduced by commit 4638de5aefe5 ("mptcp: handle local addrs announced by userspace PMs"). We can skip all these tests if the feature is not supported simply by looking for the MPTCP pm_type's sysctl knob.

One of them is TCP_INQ cmsg support introduced in commit 2c9e77659a0c ("mptcp: add TCP_INQ cmsg support"). It is possible to look for "mptcp_ioctl" in kallsyms because it was needed to introduce the mentioned feature. We can skip these tests and not set TCPINQ option if the feature is not supported.

One of them is the getsockopt(SOL_MPTCP) to get info about the MPTCP connections introduced by commit 55c42fa7fa33 ("mptcp: add MPTCP_INFO getsockopt") and the following ones. It is possible to look for "mptcp_diag_fill_info" in kallsyms because it is introduced by the mentioned feature. So we can know in advance if the feature is supported and skip the sub-test if not.

2023-06-10selftests: mptcp: sockopt: relax expected returned sizeMatthieu Baerts
Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the getsockopt(SOL_MPTCP) to get info about the MPTCP connections introduced by commit 55c42fa7fa33 ("mptcp: add MPTCP_INFO getsockopt") and the following ones. We cannot guess in advance which sizes the kernel will returned: older kernel can returned smaller sizes, e.g. recently the tcp_info structure has been modified in commit 71fc704768f6 ("tcp: add rcv_wnd and plb_rehash to TCP_INFO") where a new field has been added. The userspace can also expect a smaller size if it is compiled with old uAPI kernel headers. So for these sizes, we can only check if they are above a certain threshold, 0 for the moment. We can also only compared sizes with the ones set by the kernel.

Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the fullmesh flag that can be given to the MPTCP in-kernel path-manager and introduced in commit 2843ff6f36db ("mptcp: remote addresses fullmesh"). If the flag is not visible in the dump after having set it, we don't check the content. Note that if we expect to have this feature and SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var is set to 1, we always check the content to avoid regressions.

Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the checks of the default limits returned by the MPTCP in-kernel path-manager. The default values have been modified by commit 72bcbc46a5c3 ("mptcp: increase default max additional subflows to 2"). Instead of comparing with hardcoded values, we can get the default one and compare with them. Note that if we expect to have the latest version, we continue to check the hardcoded values to avoid unexpected behaviour changes.

One of them is the reporting of the MPTCP sockets being used, introduced by commit c558246ee73e ("mptcp: add statistics for mptcp socket in use"). Similar to the parent commit, it looks like there is no good pre-check to do here, i.e. dedicated function available in kallsyms. Instead, we try to get info and if nothing is returned, the test is marked as skipped.

Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features.

It looks like there is no good pre-check to do here, i.e. dedicated function available in kallsyms. Instead, we try to get info if nothing is returned, the test is marked as skipped. That's not ideal because something could be wrong with the feature and instead of reporting an error, the test could be marked as skipped. If we know in advanced that the feature is supposed to be supported, the tester can set SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var to 1: in this case the test will report an error instead of marking the test as skipped if nothing is returned.

One of them is the full support of disconnections from the userspace introduced by commit b29fcfb54cd7 ("mptcp: full disconnect implementation"). It is possible to look for "mptcp_pm_data_reset" in kallsyms because a preparation patch added it to ease the introduction of the mentioned feature.

It is possible to look for "__ip_sock_set_tos" in kallsyms because IP(V6)_TRANSPARENT socket option support has been added after TOS support which came with the required infrastructure in MPTCP sockopt code. To support TOS, the following function has been exported (T). Not great but better than checking for a specific kernel version.

The lock around counting the channel queue length in the BIODASDINFO ioctl was incorrectly changed to the dasd_block->queue_lock with commit 583d6535cb9d ("dasd: remove dead code"). This can lead to endless list iterations and a subsequent crash. The queue_lock is supposed to be used only for queue lists belonging to dasd_block. For dasd_device related queue lists the ccwdev lock must be used. Fix the mentioned issues by correctly using the ccwdev lock instead of the queue lock.

2023-06-09tools/virtio: use canonical ftrace pathRoss Zwisler
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A few spots in tools/virtio still refer to this older debugfs path, so let's update them to avoid confusion.

2023-06-09net/sched: cls_u32: Fix reference counter leak leading to overflowLee Jones
In the event of a failure in tcf_change_indev(), u32_set_parms() will immediately return without decrementing the recently incremented reference counter. If this happens enough times, the counter will rollover and the reference freed, leading to a double free which can be used to do 'bad things'. In order to prevent this, move the point of possible failure above the point where the reference counter is incremented. Also save any meaningful return values to be applied to the return data at the appropriate point in time. This issue was caught with KASAN.

As shown in [1], out-of-bounds access occurs in two cases: 1)when the qdisc of the taprio type is used to replace the previously configured taprio, count and offset in tc_to_txq can be set to 0. In this case, the value of *txq in taprio_next_tc_txq() will increases continuously. When the number of accessed queues exceeds the number of queues on the device, out-of-bounds access occurs. 2)When packets are dequeued, taprio can be deleted. In this case, the tc rule of dev is cleared. The count and offset values are also set to 0. In this case, out-of-bounds access is also caused. Now the restriction on the queue number is added.

Descriptors from index 0 through gq->ring_size - 1 contain actual information, and the last index (gq->ring_size) should have LINKFIX to indicate the first index 0 descriptor. However, the LINKFIX value is missing, causing the timestamp feature to stop after all descriptors are used. To resolve this issue, set the LINKFIX to the timestamp descritors.

Instead of relying on skb->transport_header being set correctly, opt instead to parse the L3 header length out of the L3 headers for both IPv4/IPv6 when the Extended Layer Op for tcp/udp is used. This fixes a bug if GRO is disabled, when GRO is disabled skb->transport_header is set by __netif_receive_skb_core() to point to the L3 header, it's later fixed by the upper protocol layers, but act_pedit will receive the SKB before the fixups are completed. The existing behavior causes the following to edit the L3 header if GRO is disabled instead of the UDP header: tc filter add dev eth0 ingress protocol ip flower ip_proto udp \ dst_ip 192.168.1.3 action pedit ex munge udp set dport 18053 Also re-introduce a rate-limited warning if we were unable to extract the header offset when using the 'ex' interface.

2023-06-08igb: Fix extts capture value format for 82580/i354/i350Yuezhen Luan
82580/i354/i350 features circle-counter-like timestamp registers that are different with newer i210. The EXTTS capture value in AUXTSMPx should be converted from raw circle counter value to timestamp value in resolution of 1 nanosec by the driver. This issue can be reproduced on i350 nics, connecting an 1PPS signal to a SDP pin, and run 'ts2phc' command to read external 1PPS timestamp value. On i210 this works fine, but on i350 the extts is not correctly converted. The i350/i354/82580's SYSTIM and other timestamp registers are 40bit counters, presenting time range of 2^40 ns, that means these registers overflows every about 1099s. This causes all these regs can't be used directly in contrast to the newer i210/i211s. The igb driver needs to convert these raw register values to valid time stamp format by using kernel timecounter apis for i350s families. Here the igb_extts() just forgot to do the convert.

2023-06-08ping6: Fix send to link-local addresses with VRF.Guillaume Nault
Ping sockets can't send packets when they're bound to a VRF master device and the output interface is set to a slave device. For example, when net.ipv4.ping_group_range is properly set, so that ping6 can use ping sockets, the following kind of commands fails: $ ip vrf exec red ping6 fe80::854:e7ff:fe88:4bf1%eth1 What happens is that sk->sk_bound_dev_if is set to the VRF master device, but 'oif' is set to the real output device. Since both are set but different, ping_v6_sendmsg() sees their value as inconsistent and fails. Fix this by allowing 'oif' to be a slave device of ->sk_bound_dev_if. This fixes the following kselftest failure: $ ./fcnal-test.sh -t ipv6_ping [...] TEST: ping out, vrf device+address bind - ns-B IPv6 LLA [FAIL] Reported-by: Mirsad Todorovac <mirsad.todorovac@alu.unizg.hr> Closes: https://lore.kernel.org/netdev/b6191f90-ffca-dbca-7d06-88a9788def9c@alu.unizg.hr/ Tested-by: Mirsad Todorovac <mirsad.todorovac@alu.unizg.hr> Fixes: 5e457896986e ("net: ipv6: Fix ping to link-local addresses.")
