Make it explicit that this tool is not a drop-in replacement for ethtool.
This tool is intended for testing ethtool functionality implemented in the
kernel and should use a name that differentiates it from the ethtool
utility.

Absolute paths for the spec and schema files make the ethtool testing tool
unusable with freshly checked-out source trees. Replace absolute paths with
relative paths for both files in the Documentation/ directory.

Some distros ship with older vm_sockets.h that doesn't have VMADDR_CID_LOCAL
which causes selftests build to fail:
/tmp/work/bpf/bpf/tools/testing/selftests/bpf/prog_tests/sockmap_listen.c:261:18: error: ‘VMADDR_CID_LOCAL’ undeclared (first use in this function); did you mean ‘VMADDR_CID_HOST’?
261 | addr->svm_cid = VMADDR_CID_LOCAL;
| ^~~~~~~~~~~~~~~~
| VMADDR_CID_HOST
Workaround this issue by defining it on demand.

====================
pull-request: bpf-next 2023-04-13
We've added 260 non-merge commits during the last 36 day(s) which contain
a total of 356 files changed, 21786 insertions(+), 11275 deletions(-).
The main changes are:
1) Rework BPF verifier log behavior and implement it as a rotating log
by default with the option to retain old-style fixed log behavior,
from Andrii Nakryiko.
2) Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params, from Christian Ehrig.
3) Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton,
from Alexei Starovoitov.
4) Optimize hashmap lookups when key size is multiple of 4,
from Anton Protopopov.
5) Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps, from David Vernet.
6) Add support for stashing local BPF kptr into a map value via
bpf_kptr_xchg(). This is useful e.g. for rbtree node creation
for new cgroups, from Dave Marchevsky.
7) Fix BTF handling of is_int_ptr to skip modifiers to work around
tracing issues where a program cannot be attached, from Feng Zhou.
8) Migrate a big portion of test_verifier unit tests over to
test_progs -a verifier_* via inline asm to ease {read,debug}ability,
from Eduard Zingerman.
9) Several updates to the instruction-set.rst documentation
which is subject to future IETF standardization
(https://lwn.net/Articles/926882/), from Dave Thaler.
10) Fix BPF verifier in the __reg_bound_offset's 64->32 tnum sub-register
known bits information propagation, from Daniel Borkmann.
11) Add skb bitfield compaction work related to BPF with the overall goal
to make more of the sk_buff bits optional, from Jakub Kicinski.
12) BPF selftest cleanups for build id extraction which stand on its own
from the upcoming integration work of build id into struct file object,
from Jiri Olsa.
13) Add fixes and optimizations for xsk descriptor validation and several
selftest improvements for xsk sockets, from Kal Conley.
14) Add BPF links for struct_ops and enable switching implementations
of BPF TCP cong-ctls under a given name by replacing backing
struct_ops map, from Kui-Feng Lee.
15) Remove a misleading BPF verifier env->bypass_spec_v1 check on variable
offset stack read as earlier Spectre checks cover this,
from Luis Gerhorst.
16) Fix issues in copy_from_user_nofault() for BPF and other tracers
to resemble copy_from_user_nmi() from safety PoV, from Florian Lehner
and Alexei Starovoitov.
17) Add --json-summary option to test_progs in order for CI tooling to
ease parsing of test results, from Manu Bretelle.
18) Batch of improvements and refactoring to prep for upcoming
bpf_local_storage conversion to bpf_mem_cache_{alloc,free} allocator,
from Martin KaFai Lau.
19) Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations,
from Quentin Monnet.
20) Fix attaching fentry/fexit/fmod_ret/lsm to modules by extracting
the module name from BTF of the target and searching kallsyms of
the correct module, from Viktor Malik.
21) Improve BPF verifier handling of '<const> <cond> <non_const>'
to better detect whether in particular jmp32 branches are taken,
from Yonghong Song.
22) Allow BPF TCP cong-ctls to write app_limited of struct tcp_sock.
A built-in cc or one from a kernel module is already able to write
to app_limited, from Yixin Shen.

Pull networking fixes from Jakub Kicinski:
"Including fixes from bpf, and bluetooth.
Not all that quiet given spring celebrations, but "current" fixes are
thinning out, which is encouraging. One outstanding regression in the
mlx5 driver when using old FW, not blocking but we're pushing for a
fix.
Current release - new code bugs:
- eth: enetc: workaround for unresponsive pMAC after receiving
express traffic
Previous releases - regressions:
- rtnetlink: restore RTM_NEW/DELLINK notification behavior, keep the
pid/seq fields 0 for backward compatibility
Previous releases - always broken:
- sctp: fix a potential overflow in sctp_ifwdtsn_skip
- mptcp:
- use mptcp_schedule_work instead of open-coding it and make the
worker check stricter, to avoid scheduling work on closed
sockets
- fix NULL pointer dereference on fastopen early fallback
- skbuff: fix memory corruption due to a race between skb coalescing
and releasing clones confusing page_pool reference counting
- bonding: fix neighbor solicitation validation on backup slaves
- bpf: tcp: use sock_gen_put instead of sock_put in bpf_iter_tcp
- bpf: arm64: fixed a BTI error on returning to patched function
- openvswitch: fix race on port output leading to inf loop
- sfp: initialize sfp->i2c_block_size at sfp allocation to avoid
returning a different errno than expected
- phy: nxp-c45-tja11xx: unregister PTP, purge queues on remove
- Bluetooth: fix printing errors if LE Connection times out
- Bluetooth: assorted UaF, deadlock and data race fixes
- eth: macb: fix memory corruption in extended buffer descriptor mode
Misc:
- adjust the XDP Rx flow hash API to also include the protocol layers
over which the hash was computed"

sort__sym_from_cmp()
Addresses of two data structure members were determined before
corresponding null pointer checks in the implementation of the function
“sort__sym_from_cmp”.
Thus avoid the risk for undefined behaviour by removing extra
initialisations for the local variables “from_l” and “from_r” (also
because they were already reassigned with the same value behind this
pointer check).
This issue was detected by using the Coccinelle software.

Before exiting each test function(run_cmt/cat/mbm/mba_test()),
test results("ok","not ok") are printed by ksft_test_result() and then
temporary result files are cleaned by function
cmt/cat/mbm/mba_test_cleanup().
However, before running ksft_test_result(),
function cmt/cat/mbm/mba_test_cleanup()
has been run in each test function as follows:
cmt_resctrl_val()
cat_perf_miss_val()
mba_schemata_change()
mbm_bw_change()
Remove duplicate codes that clear each test result file,
while ensuring cleanup properly even when errors occur in each test.

tests
After creating a child process with fork() in CAT test, if a signal such
as SIGINT is received, the parent process will be terminated immediately,
and therefore the child process will not be killed and also resctrlfs is
not unmounted.
There is a signal handler registered in CMT/MBM/MBA tests, which kills
child process, unmount resctrlfs, cleanups result files, etc., if a
signal such as SIGINT is received.
Commonize the signal handler registered for CMT/MBM/MBA tests and
reuse it in CAT.
To reuse the signal handler to kill child process use global bm_pid
instead of local bm_pid.
Also, since the MBA/MBA/CMT/CAT are run in order, unregister the signal
handler at the end of each test so that the signal handler cannot be
inherited by other tests.

After creating a child process with fork() in CAT test, if an error
occurs when parent process runs cat_val() or check_results(), the child
process will not be killed and also resctrlfs is not unmounted. Also if
an error occurs when child process runs cat_val() or check_results(),
the parent process will wait for the pipe message from the child process
which will never be sent by the child process and the parent process
cannot proceed to unmount resctrlfs.
Synchronize the exits between the parent and child. An error could
occur whether in parent process or child process. The parent process
always kills the child process and runs umount_resctrlfs(). The
child process always waits to be killed by the parent process.

MBM test
There is a comment "Set up shemata with 100% allocation on the first run"
in function mbm_setup(), but there is an increment bug and the condition
"num_of_runs == 0" will never be met and write_schemata() will never be
called to set schemata to 100%. Even if write_schemata() is called in MBM
test, since it is not supported for MBM test it does not set the schemata.
This is currently fine because resctrl_val_parm->mum_resctrlfs is always 1
and umount/mount will be run in each test to set the schemata to 100%.
To support the usage when MBM test does not unmount/remount resctrl
filesystem before the test starts, fix to call write_schemata() and
set schemata properly when the function is called for the first time.
Also, remove static local variable 'num_of_runs' because this is not
needed as there is resctrl_val_param->num_of_runs which should be used
instead like in cat_setup().

Simply adding a "sleep" before checking something is usually not a good
idea because the time that has been picked can not be enough or too
much. The best is to wait for events with a timeout.
In this selftest, 'sleep 0.5' is used more than 40 times. It is always
used before calling a 'verify_*' function except for this
verify_listener_events which has been added later.
At the end, using all these 'sleep 0.5' seems to work: the slow CIs
don't complain so far. Also because it doesn't take too much time, we
can just add two more 'sleep 0.5' to uniform what is done before calling
a 'verify_*' function. For the same reasons, we can also delay a bigger
refactoring to replace all these 'sleep 0.5' by functions waiting for
events instead of waiting for a fix time and hope for the best.

'sched:sched_wakeup'
'perf sched latency' is incorrect to get process schedule latency when
it used 'sched:sched_wakeup' to analysis perf.data.
Because 'perf record' prefers to use 'sched:sched_waking' to
'sched:sched_wakeup' since commit d566a9c2d482 ("perf sched: Prefer
sched_waking event when it exists"). It's very reasonable to evaluate
process schedule latency.
Similarly, update sched latency/map/replay to use sched_waking events.
