Add an operation, SECCOMP_CLONE_FILTER, that can copy the seccomp
filters from another process to the current process.
Changes from v1 to v2:
* Fixed locking issues. Thanks Al, Alexei, and Kees :)
* Allow filters to be cloned if CAP_SYS_ADMIN or no new privs
is set
* I initially had only CAP_SYS_ADMIN, but I can't think of a
way no new privs is harmful here, so I added it. Thanks, Kees
* Switch to passing in pidfd directly rather than a pointer to a
pidfd
* This more closely aligns with other pidfd syscalls
* Fixed warning in the sample code reported by the test robot
* Various cleanups and improvements in the selftest
Note that I left in the restriction that the target process
has no seccomp filters already loaded. I could see this
limitation being removed in a later patchset, but there are
requests for this feature at present.
Finally, I re-ran the performance numbers and updated the patch
with the latest numbers. The locking changes significantly sped
up the clone operation, and it's now ~1900x faster than the
current method.

From: Chia-Yu Chang <chia-yu.chang(a)nokia-bell-labs.com>
Hello,
Please find the v17 AccECN protocol patch series, which covers the core
functionality of Accurate ECN, AccECN negotiation, AccECN TCP options,
and AccECN failure handling. The Accurate ECN draft can be found in
https://datatracker.ietf.org/doc/html/draft-ietf-tcpm-accurate-ecn-28, and it
will be RFC9768.
This patch series is part of the full AccECN patch series, which is available at
https://github.com/L4STeam/linux-net-next/commits/upstream_l4steam/
Best Regards,
Chia-Yu

2.34.1
There are currently no kernel tests that verify setting and getting
options of the team driver.
In the future, options may be added that implicitly change other
options, which will make it useful to have tests like these that show
nothing breaks. There will be a follow up patch to this that adds new
"rx_enabled" and "tx_enabled" options, which will implicitly affect the
"enabled" option value and vice versa.
The tests use teamnl to first set options to specific values and then
gets them to compare to the set values.

2.51.0.384.g4c02a37b29-goog
From: Zhou Yuhang <zhouyuhang(a)kylinos.cn>
On x86_64, the size of struct flock is 32 bytes,
and the layout of this structure may be as follows:
+------------+ offset 0
| l_type | 2 bytes
+------------+ offset 2
| l_whence | 2 bytes
+------------+ offset 4
| padding | 4 bytes
+------------+ offset 8
| l_start | 8 bytes
+------------+ offset 16
| l_len | 8 bytes
+------------+ offset 24
| l_pid | 4 bytes
+------------+ offset 28
| padding | 4 bytes
+------------+ offset 32
Flock fl and fl2 are not initialized after definition.
The padding bytes in the structure may contain random values,
which could cause memcmp() to return a non-zero value,
potentially leading to test failure. The output is as follows:
# [INFO] opened fds 3 4
# [SUCCESS] set OFD read lock on first fd
# [SUCCESS] read and write locks conflicted
# [SUCCESS] F_UNLCK test returns: locked, type 0 pid -1 len 3
# [FAIL] F_UNLCK test returns: locked, type 0 pid -1 len 3
Initialize them to zero to solve this problem.

sockmap_redir was introduced to comprehensively test the BPF redirection.
This series strives to increase the tested sockmap/sockhash code coverage;
adds support for skipping the actual redirect part, allowing to simply
SK_DROP or SK_PASS the packet.

Patch 5 ("Support no-redirect SK_DROP/SK_PASS") implements the feature.
Patches 3 ("Rename functions") and 4 ("Let test specify skel's
redirect_type") make preparatory changes.
I also took the opportunity to clean up (Patch 1, "Simplify try_recv()")
and improve a bit (Patch 2, "Fix OOB handling").
