threshold set by the net.ipv4.route.min_pmtu sysctl, and is also

Require size_out to be non-NULL if data_out is given. This prevents
accidental overwriting of process memory after the output buffer.

Right now, there is no safe way to use BPF_PROG_TEST_RUN with data_out.
This is because bpf_test_finish copies the output buffer to user space
without checking its size. This can lead to the kernel overwriting
data in user space after the buffer if xdp_adjust_head and friends are
in play.
Fix this
Use data_size_out as a size hint when copying test output to user space.
A program using BPF_PERF_OUTPUT can compare its own buffer length with
data_size_out after the syscall to detect whether truncation has taken
place. Callers which so far did not set data_size_in are not affected.

When searching for an existing link group the queue pair number is also
to be taken into consideration. When the SMC server sends a new number
in a CLC packet (keeping all other values equal) then a new link group
is to be created on the SMC client side.

In case of a non-blocking SMC socket, the initial CLC handshake is
performed over a blocking TCP connection in a worker. If the SMC socket
is released, smc_release has to wait for the blocking CLC socket
operations (e.g., kernel_connect) inside the worker.
This patch aborts a C

Check that iterating two separate hash maps produces the same
order of keys if BPF_F_ZERO_SEED is used.

BPF_F_QUERY_EFFECTIVE is in the middle of the flags valid
for BPF_MAP_CREATE. Move it to its own section to reduce confusion.

Add a new flag BPF_F_ZERO_SEED, which forces a hash map
to initialize the seed to zero. This is useful when doing
performance analysis both on individual BPF programs, as
well as the kernel's hash table implementation.

Allow forcing the seed of a hash table to zero, for deterministic
execution during benchmarking and testing.
Changes from v2:
* Change ordering of BPF_F_ZERO_SEED in linux/bpf.h
Comments adressed from v1:
* Add comment to discourage production use to linux/bpf.h
* Require CAP_SYS_ADMIN

splice(2) fails with -EINVAL when called reading on a socket with no splice_read
set in its proto_ops (such as vsock sockets). Switch this to fallbacks to a
generic_file_splice_read instead.

thank you for the patch, but let me ask you to change the subject line by
adding the expected prefixes 'net: lpc_eth: fix trivial comment typo'.
Also it would be nice to see
