2 daysbpf: Support specifying linear xdp packet data size for BPF_PROG_TEST_RUNAmery Hung1-3/+1
[ Upstream commit fe9544ed1a2e9217b2c5285c3a4ac0dc5a38bd7b ] To test bpf_xdp_pull_data(), an xdp packet containing fragments as well as free linear data area after xdp->data_end needs to be created. However, bpf_prog_test_run_xdp() always fills the linear area with data_in before creating fragments, leaving no space to pull data. This patch will allow users to specify the linear data size through ctx->data_end. Currently, ctx_in->data_end must match data_size_in and will not be the final ctx->data_end seen by xdp programs. This is because ctx->data_end is populated according to the xdp_buff passed to test_run. The linear data area available in an xdp_buff, max_linear_sz, is alawys filled up before copying data_in into fragments. This patch will allow users to specify the size of data that goes into the linear area. When ctx_in->data_end is different from data_size_in, only ctx_in->data_end bytes of data will be put into the linear area when creating the xdp_buff. While ctx_in->data_end will be allowed to be different from data_size_in, it cannot be larger than the data_size_in as there will be no data to copy from user space. If it is larger than the maximum linear data area size, the layout suggested by the user will not be honored. Data beyond max_linear_sz bytes will still be copied into fragments. Finally, since it is possible for a NIC to produce a xdp_buff with empty linear data area, allow it when calling bpf_test_init() from bpf_prog_test_run_xdp() so that we can test XDP kfuncs with such xdp_buff. This is done by moving lower-bound check to callers as most of them already do except bpf_prog_test_run_skb(). The change also fixes a bug that allows passing an xdp_buff with data < ETH_HLEN. This can happen when ctx is used and metadata is at least ETH_HLEN.

2 daysbpf: Fix an issue in bpf_prog_test_run_xdp when page size greater than 4KYonghong Song2-8/+96
[ Upstream commit 4fc012daf9c074772421c904357abf586336b1ca ] The bpf selftest xdp_adjust_tail/xdp_adjust_frags_tail_grow failed on arm64 with 64KB page: xdp_adjust_tail/xdp_adjust_frags_tail_grow:FAIL In bpf_prog_test_run_xdp(), the xdp->frame_sz is set to 4K, but later on when constructing frags, with 64K page size, the frag data_len could be more than 4K. This will cause problems in bpf_xdp_frags_increase_tail(). To fix the failure, the xdp->frame_sz is set to be PAGE_SIZE so kernel can test different page size properly. With the kernel change, the user space and bpf prog needs adjustment. Currently, the MAX_SKB_FRAGS default value is 17, so for 4K page, the maximum packet size will be less than 68K. To test 64K page, a bigger maximum packet size than 68K is desired. So two different functions are implemented for subtest xdp_adjust_frags_tail_grow. Depending on different page size, different data input/output sizes are used to adapt with different page size.

Additionally, given that IFLA_IFNAME also expects a null-terminated string, callers of rtaddr_add_str{,sz}() could simply use the rtaddr_add_strsz() variant. (which has been renamed to remove the trailing `sz`) memset() has been used for this function since it is unchecked and thus circumvents the issue discussed in the previous paragraph.

[ Upstream commit 2c28ee720ad14f58eb88a97ec3efe7c5c315ea5d ] Jakub reported increased flakiness in bond_macvlan_ipvlan.sh on regular kernel, while the tests consistently pass on a debug kernel. This suggests a timing-sensitive issue. To mitigate this, introduce a short sleep before each xvlan_over_bond connectivity check. The delay helps ensure neighbor and route cache have fully converged before verifying connectivity. The sleep interval is kept minimal since check_connection() is invoked nearly 100 times during the test.

[ Upstream commit ae24fc8a16b0481ea8c5acbc66453c49ec0431c4 ] Currently, test_perf_branches_no_hw() relies on the busy loop within test_perf_branches_common() being slow enough to allow at least one perf event sample tick to occur before starting to tear down the backing perf event BPF program. With a relatively small fixed iteration count of 1,000,000, this is not guaranteed on modern fast CPUs, resulting in the test run to subsequently fail with the following: bpf_testmod.ko is already unloaded.

On a modern CPU (i.e. one with a 3.5 GHz clock rate), executing 1 million increments of a volatile integer can take significantly less than 1 millisecond. If the spin loop and detachment of the perf event BPF program elapses before the first 1 ms sampling interval elapses, the perf event will never end up firing. Fix this by bumping the loop iteration counter a little within test_perf_branches_common(), along with ensuring adding another loop termination condition which is directly influenced by the backing perf event BPF program executing. Notably, a concious decision was made to not adjust the sample_freq value as that is just not a reliable way to go about fixing the problem. It effectively still leaves the race window open.

[ Upstream commit 6457595db9870298ee30b6d75287b8548e33fe19 ] In rare cases, when the test environment is very slow, some userspace tests can fail because some expected events have not been seen. Because the tests are expecting a long on-going connection, and they are not waiting for the end of the transfer, it is fine to make the connection longer. This connection will be killed at the end, after the verifications, so making it longer doesn't change anything, apart from avoid it to end before the end of the verifications To play it safe, all endpoints tests not waiting for the end of the transfer are now sharing a longer file (128KB) at slow speed.

2025-11-24selftests: mptcp: connect: trunc: read all recv dataMatthieu Baerts (NGI0)1-5/+13
commit ee79980f7a428ec299f6261bea4c1084dcbc9631 upstream. MPTCP Join "fastclose server" selftest is sometimes failing because the client output file doesn't have the expected size, e.g. 296B instead of 1024B. When looking at a packet trace when this happens, the server sent the expected 1024B in two parts -- 100B, then 924B -- then the MP_FASTCLOSE. It is then strange to see the client only receiving 296B, which would mean it only got a part of the second packet. The problem is then not on the networking side, but rather on the data reception side. When mptcp_connect is launched with '-f -1', it means the connection might stop before having sent everything, because a reset has been received. When this happens, the program was directly stopped. But it is also possible there are still some data to read, simply because the previous 'read' step was done with a buffer smaller than the pending data, see do_rnd_read(). In this case, it is important to read what's left in the kernel buffers before stopping without error like before. SIGPIPE is now ignored, not to quit the app before having read everything.

The tracing selftest "event-filter-function.tc" was failing because it first runs the "sample_events" function that triggers the kmem_cache_free event and it looks at what function was used during a call to "ls". But the first time it calls this, it could trigger events that are used to pull pages into the page cache. The rest of the test uses the function it finds during that call to see if it will be called in subsequent "sample_events" calls. But if there's no need to pull pages into the page cache, it will not trigger that function and the test will fail. Call the "sample_events" twice to trigger all the page cache work before it calls it to find a function to use in subsequent checks.

[ Upstream commit 57531b3416448d1ced36a2a974a4085ec43d57b0 ] It seems that most of the tests prepare the interfaces once before the test run (setup_prepare()), rely on setup_wait() to wait for link and only then run the test(s). local_termination brings the physical interfaces down and up during test run but never wait for them to come up. If the auto-negotiation takes some seconds, first test packets are being lost, which leads to false-negative test results. Use setup_wait() in run_test() to make sure auto-negotiation has been completed after all simple_if_init() calls on physical interfaces and test packets will not be lost because of the race against link establishment.

2025-11-24selftests/net: use destination options instead of hop-by-hopAnubhav Singh1-2/+2
[ Upstream commit f8e8486702abb05b8c734093aab1606af0eac068 ] The GRO self-test, gro.c, currently constructs IPv6 packets containing a Hop-by-Hop Options header (IPPROTO_HOPOPTS) to ensure the GRO path correctly handles IPv6 extension headers. However, network elements may be configured to drop packets with the Hop-by-Hop Options header (HBH). This causes the self-test to fail in environments where such network elements are present. To improve the robustness and reliability of this test in diverse network environments, switch from using IPPROTO_HOPOPTS to IPPROTO_DSTOPTS (Destination Options). The Destination Options header is less likely to be dropped by intermediate routers and still serves the core purpose of the test: validating GRO's handling of an IPv6 extension header. This change ensures the test can execute successfully without being incorrectly failed by network policies outside the kernel's control.

2025-10-29selftests: net: fix server bind failure in sctp_vrf.shXin Long2-43/+47
[ Upstream commit a73ca0449bcb7c238097cc6a1bf3fd82a78374df ] sctp_vrf.sh could fail: TEST 12: bind vrf-2 & 1 in server, connect from client 1 & 2, N [FAIL] not ok 1 selftests: net: sctp_vrf.sh # exit=3 The failure happens when the server bind in a new run conflicts with an existing association from the previous run: [1] ip netns exec $SERVER_NS ./sctp_hello server ... [2] ip netns exec $CLIENT_NS ./sctp_hello client ... [3] ip netns exec $SERVER_NS pkill sctp_hello ... [4] ip netns exec $SERVER_NS ./sctp_hello server ... It occurs if the client in [2] sends a message and closes immediately. With the message unacked, no SHUTDOWN is sent. Killing the server in [3] triggers a SHUTDOWN the client also ignores due to the unacked message, leaving the old association alive. This causes the bind at [4] to fail until the message is acked and the client responds to a second SHUTDOWN after the server’s T2 timer expires (3s). This patch fixes the issue by preventing the client from sending data. Instead, the client blocks on recv() and waits for the server to close. It also waits until both the server and the client sockets are fully released in stop_server and wait_client before restarting. Additionally, replace 2>&1 >/dev/null with -q in sysctl and grep, and drop other redundant 2>&1 >/dev/null redirections, and fix a typo from N to Y (connect successfully) in the description of the last test.

[ Upstream commit e603a342cf7ecd64ef8f36207dfe1caacb9e2583 ] We started getting a crash in BPF CI, which seems to originate from test_parse_test_list_file() test and is happening at this line: ASSERT_OK(strcmp("test_with_spaces", set.tests[0].name), "test 0 name"); One way we can crash there is if set.cnt zero, which is checked for with ASSERT_EQ() above, but we proceed after this regardless of the outcome. Instead of crashing, we should bail out with test failure early. Similarly, if parse_test_list_file() fails, we shouldn't be even looking at set, so bail even earlier if ASSERT_OK() fails.

2025-10-19selftests: mptcp: join: validate C-flag + def limitMatthieu Baerts (NGI0)1-0/+11
commit 008385efd05e04d8dff299382df2e8be0f91d8a0 upstream. The previous commit adds an exception for the C-flag case. The 'mptcp_join.sh' selftest is extended to validate this case. In this subtest, there is a typical CDN deployment with a client where MPTCP endpoints have been 'automatically' configured: - the server set net.mptcp.allow_join_initial_addr_port=0 - the client has multiple 'subflow' endpoints, and the default limits: not accepting ADD_ADDRs. Without the parent patch, the client is not able to establish new subflows using its 'subflow' endpoints. The parent commit fixes that. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
