[Kernel-packages] [Bug 2040245] Re: apparmor oops when racing to retrieve a notification
Verification passed for mantic-linux-laptop. I ran the AppArmor QA Regression Tests [1] and specific prompting tests [2]. The QA Regression Tests that failed were due to a timeout because I'm emulating in my machine, but they pass when the timeout is increased. georgia@sec-mantic-arm64:~$ uname -a Linux sec-mantic-arm64 6.5.0-1007-laptop #10-Ubuntu SMP PREEMPT_DYNAMIC Wed Nov 22 20:27:28 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux georgia@sec-mantic-arm64:~/apparmor/tests/regression/apparmor$ sudo ./prompt.sh xpass: PROMPT (allow (rule link file l)) - root xpass: PROMPT (allow (flag link file l)) - root xpass: PROMPT (allow (rule mmap_exec file rwm)) - root xpass: PROMPT (allow (flag mmap_exec file rwm)) - root xpass: PROMPT (allow (rule lock file rwk)) - root xpass: PROMPT (allow (flag lock file rwk)) - root xpass: PROMPT (allow (rule exec file rix)) - root xpass: PROMPT (allow (flag exec file rix)) - root xpass: PROMPT (allow (rule exec file ux)) - root xpass: PROMPT (allow (flag exec file ux)) - root georgia@sec-mantic-arm64:~/qrt-test-apparmor$ sudo ./test-apparmor.py ERROR: test_dbus (__main__.ApparmorTest.test_dbus) Test dbus apparmor activation from dbus-tests -- Traceback (most recent call last): File "/home/georgia/qrt-test-apparmor/./test-apparmor.py", line 719, in test_dbus rc, report = testlib.cmd(['/usr/lib/dbus-1.0/installed-tests/dbus/test-apparmor-activation.sh'], ^^^ File "/home/georgia/qrt-test-apparmor/testlib.py", line 471, in cmd out, outerr = sp.communicate(input, timeout=timeout) ^^ File "/usr/lib/python3.11/subprocess.py", line 1209, in communicate stdout, stderr = self._communicate(input, endtime, timeout) ^^ File "/usr/lib/python3.11/subprocess.py", line 2109, in _communicate self._check_timeout(endtime, orig_timeout, stdout, stderr) File "/usr/lib/python3.11/subprocess.py", line 1253, in _check_timeout raise TimeoutExpired( subprocess.TimeoutExpired: Command '['/usr/lib/dbus-1.0/installed-tests/dbus/test-apparmor-activation.sh']' timed out after 5 seconds - running attach_disconnected Fatal Error (unix_fd_server): Unable to run test sub-executable PASSED: aa_exec access at_secure introspect capabilities changeprofile onexec changehat changehat_fork changehat_misc chdir clone coredump deleted e2e environ exec exec_qual fchdir fd_inheritance fork i18n link link_subset mkdir mmap mount mult_mount named_pipe namespaces net_raw open openat pipe pivot_root posix_ipc ptrace pwrite query_label regex rename readdir rw socketpair swap sd_flags setattr symlink syscall sysv_ipc tcp unix_fd_server unix_socket_pathname unix_socket_abstract unix_socket_unnamed unix_socket_autobind unlink userns xattrs xattrs_profile longpath nfs dbus_eavesdrop dbus_message dbus_service dbus_unrequested_reply io_uring aa_policy_cache exec_stack nnp stackonexec stackprofile FAILED: attach_disconnected make: *** [Makefile:402: alltests] Error 1 - ERROR: test_0 (__main__.TestLogprof.test_0) test 'ping' -- Traceback (most recent call last): File "/tmp/testlib2jc8hiih/source/mantic/apparmor-4.0.0~alpha2/utils/test/common_test.py", line 90, in stub_test self._run_test(test_data, expected) File "/tmp/testlib2jc8hiih/source/mantic/apparmor-4.0.0~alpha2/utils/test/test-logprof.py", line 99, in _run_test self.process.wait(timeout=0.2) File "/usr/lib/python3.11/subprocess.py", line 1264, in wait return self._wait(timeout=timeout) ^^^ File "/usr/lib/python3.11/subprocess.py", line 2038, in _wait raise TimeoutExpired(self.args, timeout) subprocess.TimeoutExpired: Command '['/usr/bin/python3', '../aa-logprof', '--json', '--configdir', './', '-f', './logprof/ping.auditlog', '-d', '/tmp/aa-test-tkkg1ex3/profiles', '--no-check-mountpoint']' timed out after 0.2 seconds -- Ran 62 tests in 43542.817s FAILED (failures=3, errors=1, skipped=3) Rerunning failing tests increasing the timeout georgia@sec-mantic-arm64:~/qrt-test-apparmor$ sudo ./test-apparmor.py ApparmorTest.test_dbus Skipping private tests . -- Ran 1 test in 19.786s OK georgia@sec-mantic-arm64:~/apparmor-4.0.0~alpha2/tests/regression/apparmor$ sudo bash ./attach_disconnected.sh georgia@sec-mantic-arm64:~/apparmor-4.0.0~alpha2/tests/regression/apparmor$ echo $? 0 georgia@sec-mantic-arm64:~/apparmor-4.0.0~alpha2/utils/test$ python3

This bug is awaiting verification that the linux-lowlatency-
hwe-6.5/6.5.0-14.14.1~22.04.1 kernel in -proposed solves the problem.
Please test the kernel and update this bug with the results. If the
problem is solved, change the tag 'verification-needed-jammy-linux-
lowlatency-hwe-6.5' to 'verification-done-jammy-linux-lowlatency-
hwe-6.5'. If the problem still exists, change the tag 'verification-
needed-jammy-linux-lowlatency-hwe-6.5' to 'verification-failed-jammy-
linux-lowlatency-hwe-6.5'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 2040245] Re: apparmor oops when racing to retrieve a notification
This bug is awaiting verification that the linux-gcp/6.5.0-1010.10
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-mantic-linux-gcp' to 'verification-done-mantic-
linux-gcp'. If the problem still exists, change the tag 'verification-
needed-mantic-linux-gcp' to 'verification-failed-mantic-linux-gcp'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 2040245] Re: apparmor oops when racing to retrieve a notification
This bug is awaiting verification that the linux/6.5.0-12.12 kernel in
-proposed solves the problem. Please test the kernel and update this bug
with the results. If the problem is solved, change the tag
'verification-needed-mantic-linux' to 'verification-done-mantic-linux'.
If the problem still exists, change the tag 'verification-needed-mantic-
linux' to 'verification-failed-mantic-linux'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!
