Extend tc_flower to test plain ingress device matching and also
tc_shblock to test ingress device matching on shared block.
Add new tc_flower_router.sh where ingress device matching on egress
(after routing) is done.

Audit tests count the total number of messages sent and compares
with total number of CMSG received on error queue. Example:
udp gso zerocopy timestamp audit
udp rx: 1599 MB/s 1166414 calls/s
udp tx: 1615 MB/s 27395 calls/s 27395 msg/s
udp rx: 1634 MB/s 1192261 calls/s
udp tx: 1633 MB/s 27699 calls/s 27699 msg/s
udp rx: 1633 MB/s 1191358 calls/s
udp tx: 1631 MB/s 27678 calls/s 27678 msg/s
Summary over 4.000 seconds...
sum udp tx: 1665 MB/s 82772 calls (27590/s) 82772 msgs (27590/s)
Tx Timestamps: 82772 received 0 errors
Zerocopy acks: 82772 received
Errors are thrown if CMSG count does not equal send count,
example:
Summary over 4.000 seconds...
sum tcp tx: 7451 MB/s 493706 calls (123426/s) 493706 msgs (123426/s)
./udpgso_bench_tx: Unexpected number of Zerocopy completions: 493706 expected 493704 received
Also reduce individual test time from 4 to 3 seconds so that
overall test time does not increase significantly.

This enhancement adds options that facilitate load testing with
additional TX CMSG options, and to optionally print results of
various send CMSG operations.
These options are especially useful in isolating situations
where error-queue messages are lost when combined with other
CMSG operations (e.g. SO_ZEROCOPY).
New options:
-a - count all CMSG messages and match to sent messages
-T - add TX CMSG that requests TX software timestamps
-H - similar to -T except request TX hardware timestamps
-P - call poll() before reading error queue
-v - print detailed results
v2: Enhancements as per Willem de Bruijn <willemb@google.com>
- Updated control and buffer parameters for recvmsg
- poll() parameter cleanup
- fail on bad audit results
- remove TOS options
- improved reporting
v3: Enhancements as per Willem de Bruijn <willemb@google.com>
- add SOF_TIMESTAMPING_OPT_TSONLY to eliminate MSG_TRUNC
- general code cleanup

Test the PTP Physical Hardware Clock functionality using the "phc_ctl" (a
part of "linuxptp").
The test contains three sub-tests:
* "settime" test
* "adjtime" test
* "adjfreq" test
"settime" test:
* set the PHC time to 0 seconds.
* wait for 120.5 seconds.
* check if PHC time equal to 120.XX seconds.
"adjtime" test:
* set the PHC time to 0 seconds.
* adjust the time by 10 seconds.
* check if PHC time equal to 10.XX seconds.
"adjfreq" test:
* adjust the PHC frequency to be 1% faster.
* set the PHC time to 0 seconds.
* wait for 100.5 seconds.
* check if PHC time equal to 101.XX seconds.
Usage:
$ ./phc.sh /dev/ptp<X>
It is possible to run a subset of the tests, for example:
* To run only the "settime" test:
$ TESTS="settime" ./phc.sh /dev/ptp<X>

Logan noticed that devm_memremap_pages_release() kills the percpu_ref
drops all the page references that were acquired at init and then
immediately proceeds to unplug, arch_remove_memory(), the backing pages
for the pagemap. If for some reason device shutdown actually collides
with a busy / elevated-ref-count page then arch_remove_memory() should
be deferred until after that reference is dropped.
As it stands the "wait for last page ref drop" happens *after*
devm_memremap_pages_release() returns, which is obviously too late and
can lead to crashes.
Fix this situation by assigning the responsibility to wait for the
percpu_ref to go idle to devm_memremap_pages() with a new ->cleanup()
callback. Implement the new cleanup callback for all
devm_memremap_pages() users: pmem, devdax, hmm, and p2pdma.

If the leftmost parent node of the tree has does not have a child
on the left side, then trie_get_next_key (and bpftool map dump) will
not look at the child on the right. This leads to the traversal
missing elements.
Lookup is not affected.
Update selftest to handle this case.
Reproducer:
bpftool map create /sys/fs/bpf/lpm type lpm_trie key 6 \
value 1 entries 256 name test_lpm flags 1
bpftool map update pinned /sys/fs/bpf/lpm key 8 0 0 0 0 0 value 1
bpftool map update pinned /sys/fs/bpf/lpm key 16 0 0 0 0 128 value 2
bpftool map dump pinned /sys/fs/bpf/lpm
Returns only 1 element. (2 expected)

6) Fix libbpf's libbpf__probe_raw_btf to return an fd instead of 0/1 (for

vm test build fails when test is built by itself using
make -C tools/testing/selftests/vm

cd tools/testing/selftests/vm; make
When the test is built invoking its Makefile directly, it defines
OUTPUT which conflicts with lib.mk's logic to install headers.

In commit 9a5ab8bf1d6d ("tools: bpftool: turn err() and info() macros
into functions") one case of error reporting was special cased, so it
could report a lookup error for a specific key when dumping the map
element. What the code forgot to do is to wrap the key and value keys
into a JSON object, so an example output of pretty JSON dump of a
sockhash map (which does not support looking up its values) is:
[
"key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00"
],
"value": {
"error": "Operation not supported"
},
"key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01"
],
"value": {
"error": "Operation not supported"
}
]
Note the key-value pairs inside the toplevel array. They should be
wrapped inside a JSON object, otherwise it is an invalid JSON. This
commit fixes this, so the output now is:
[{
"key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00"
],
"value": {
"error": "Operation not supported"
}
},{
"key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01"
],
"value": {
"error": "Operation not supported"
}
}
]

Pull pidfd fixes from Christian Brauner:
"The contains two small patches to the pidfd samples and test binaries
respectively.
They were lacking appropriate ifdefines for __NR_pidfd_send_signal and
could hence lead to compilation errors when that was not defined.
This was spotted on mips independently by Guenter Roeck (who was kind
enough to send a fix for the samples binary) and Arnd who spotted it
in linux-next.
Apart from these two patches, there's also a patch to update the
comments for the pidfd_send_signal() syscall which were slightly
wrong/inconsistenly worded"
* tag 'pidfd-fixes-v5.2-rc4' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux:
