Hi all,
In the kernel 6.5-rc5 build on Ubuntu 22.04 LTS (jammy jellyfish) on a Ryzen 7950 assembled box, vanilla torvalds tree kernel, the test test_unix_oob unexpectedly fails:
# selftests: net/af_unix: test_unix_oob # Test 2 failed, sigurg 23 len 63 OOB %
It is this code:
/* Test 2: * Verify that the first OOB is over written by * the 2nd one and the first OOB is returned as * part of the read, and sigurg is received. */ wait_for_data(pfd, POLLIN | POLLPRI); len = 0; while (len < 70) len = recv(pfd, buf, 1024, MSG_PEEK); len = read_data(pfd, buf, 1024); read_oob(pfd, &oob); if (!signal_recvd || len != 127 || oob != '#') { fprintf(stderr, "Test 2 failed, sigurg %d len %d OOB %c\n", signal_recvd, len, oob); die(1); }
In 6.5-rc4, this test was OK, so it might mean we have a regression?
marvin@defiant:~/linux/kernel/linux_torvalds$ grep test_unix_oob ../kselftest-6.5-rc4-1.log /net/af_unix/test_unix_oob # selftests: net/af_unix: test_unix_oob ok 2 selftests: net/af_unix: test_unix_oob marvin@defiant:~/linux/kernel/linux_torvalds$
Hope this helps.
NOTE: the kernel is vanilla torvalds tree, only "dirty" because the selftests were modified.
Kind regards, Mirsad Todorovac
