There is no need for tests other than amx_test to enable dynamic xsave
states. Remove the call to vm_xsave_req_perm from generic code,
and move it inside the test. While at it, allow customizing the bit
that is requested, so that future tests can use it differently.

Don't skip the vmcall() in l2_guest_code() prior to re-entering L2, doing
so will result in L2 running to completion, popping '0' off the stack for
RET, jumping to address '0', and ultimately dying with a triple fault
shutdown.
It's not at all obvious why the test re-enters L2 and re-executes VMCALL,
but presumably it serves a purpose. The VMX path doesn't skip vmcall(),
and the test can't possibly have passed on SVM, so just do what VMX does.

The lirc.h file is an old copy of lirc.h from the kernel sources. It is
out of date, and the bpf lirc tests don't need a new copy anyway. As
long as /usr/include/linux/lirc.h is from kernel v5.2 or newer, the tests
will compile fine.

We have some many cases that will create child process as well, such as
pidfd_wait. Previously, we will signal/kill the parent process when it
is time out, but this signal will not be sent to its child process. In
such case, if child process doesn't terminate itself, ksefltest framework
will hang forever.
Here we group all its child processes so that kill() can signal all of
them in timeout.

Use 'tee' to send the test output to stdout in addition to the current
output file. This makes the output easier to handle in automated test
systems and is superior to only later dumping the output file contents
to stdout, since this way the test output can be interleaved with other
log messages, like from the kernel, so that chronology is preserved,
making it easier to detect issues.

The timeout setting for the rtc kselftest is currently 90 seconds. This
setting is used by the kselftest runner to stop running a test if it
takes longer than the assigned value.
However, two of the test cases inside rtc set alarms. These alarms are
set to the next beginning of the minute, so each of these test cases may
take up to, in the worst case, 60 seconds.
In order to allow for all test cases in rtc to run, even in the worst
case, when using the kselftest runner, the timeout value should be
increased to at least 120. Set it to 180, so there's some additional
slack.
Correct operation can be tested by running the following command right
after the start of a minute (low second count), and checking that all
test cases run:
./run_kselftest.sh -c rtc

Python 3.10.0 contains:

It causes importlib.util to no longer import importlib.abs, which leads

sdir-home-migrate
[Unit: hisi_sccl,hha]
$ sudo ./perf stat -e sdir-home-migrate

\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event>event selector. use 'perf list' to list available events
To support, add an extra PMU event symbol type for "baz", and add a new
rule in the bison file.

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.
Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.
This patch restores the previous behaviour for non-libpfm4 events.

Perf script was failed to print the phys_addr for SPE profiling.
One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
attribute set, perf script then exits with error.
Now referring to 'addr', use evsel__do_check_stype() to check the type.
Before:

store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
# perf script -F pid,tid,addr,phys_addr

Introduce 4 new netlink-based XDP APIs for attaching, detaching, and
querying XDP programs:
- bpf_xdp_attach;
- bpf_xdp_detach;
- bpf_xdp_query;
- bpf_xdp_query_id.
These APIs replace bpf_set_link_xdp_fd, bpf_set_link_xdp_fd_opts,
bpf_get_link_xdp_id, and bpf_get_link_xdp_info APIs ([0]). The latter
don't follow a consistent naming pattern and some of them use
non-extensible approaches (e.g., struct xdp_link_info which can't be
modified without breaking libbpf ABI).
The approach I took with these low-level XDP APIs is similar to what we
did with low-level TC APIs. There is a nice duality of bpf_tc_attach vs
bpf_xdp_attach, and so on. I left bpf_xdp_attach() to support detaching
when -1 is specified for prog_fd for generality and convenience, but
bpf_xdp_detach() is preferred due to clearer naming and associated
semantics. Both bpf_xdp_attach() and bpf_xdp_detach() accept the same
opts struct allowing to specify expected old_prog_fd.
While doing the refactoring, I noticed that old APIs require users to
specify opts with old_fd == -1 to declare "don't care about already
attached XDP prog fd" condition. Otherwise, FD 0 is assumed, which is
essentially never an intended behavior. So I made this behavior
consistent with other kernel and libbpf APIs, in which zero FD means "no
FD". This seems to be more in line with the latest thinking in BPF land
and should cause less user confusion, hopefully.
For querying, I left two APIs, both more generic bpf_xdp_query()
allowing to query multiple IDs and attach mode, but also
a specialization of it, bpf_xdp_query_id(), which returns only requested
prog_id. Uses of prog_id returning bpf_get_link_xdp_id() were so
prevalent across selftests and samples, that it seemed a very common use
case and using bpf_xdp_query() for doing it felt very cumbersome with
a highly branches if/else chain based on flags and attach mode.
Old APIs are scheduled for deprecation in libbpf 0.8 release.

Enact deprecation of legacy BPF map definition in SEC("maps") ([0]). For
the definitions themselves introduce LIBBPF_STRICT_MAP_DEFINITIONS flag
for libbpf strict mode. If it is set, error out on any struct
bpf_map_def-based map definition. If not set, libbpf will print out
a warning for each legacy BPF map to raise awareness that it goes away.
For any use of BPF_ANNOTATE_KV_PAIR() macro providing a legacy way to
associate BTF key/value type information with legacy BPF map definition,
warn through libbpf's pr_warn() error message (but don't fail BPF object
open).
BPF-side struct bpf_map_def is marked as deprecated. User-space struct
bpf_map_def has to be used internally in libbpf, so it is left
untouched. It should be enough for bpf_map__def() to be marked
deprecated to raise awareness that it goes away.
bpftool is an interesting case that utilizes libbpf to open BPF ELF
object to generate skeleton. As such, even though bpftool itself uses
full on strict libbpf mode (LIBBPF_STRICT_ALL), it has to relax it a bit
for BPF map definition handling to minimize unnecessary disruptions. So
opt-out of LIBBPF_STRICT_MAP_DEFINITIONS for bpftool. User's code that
will later use generated skeleton will make its own decision whether to
enforce LIBBPF_STRICT_MAP_DEFINITIONS or not.
There are few tests in selftests/bpf that are consciously using legacy
BPF map definitions to test libbpf functionality. For those, temporary
opt out of LIBBPF_STRICT_MAP_DEFINITIONS mode for the duration of those
tests.

MPJ ipv6 selftests currently lack per link route to the server
net. Additionally, ipv6 subflows endpoints are created without any
interface specified. The end-result is that in ipv6 self-tests
subflows are created all on the same link, leading to expected delays
and sporadic self-tests failures.
Fix the issue by adding the missing setup bits.

CONFIG_NF_CONNTRACK=m. It would be useful to allow building as long as
it is set to module or built-in, even though in case of building as
module, user would need to load it before running the selftest. Note
that this also allows building selftest when CONFIG_NF_CONNTRACK is

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, bpf.
Quite a handful of old regression fixes but most of those are
pre-5.16.
Current release - regressions:
- fix memory leaks in the skb free deferral scheme if upper layer
protocols are used, i.e. in-kernel TCP readers like TLS
Current release - new code bugs:
- nf_tables: fix NULL check typo in _clone() functions
- change the default to y for Vertexcom vendor Kconfig
- a couple of fixes to incorrect uses of ref tracking
- two fixes for constifying netdev->dev_addr
Previous releases - regressions:
- bpf:
- various verifier fixes mainly around register offset handling
when passed to helper functions
- fix mount source displayed for bpffs (none -> bpffs)
- bonding:
- fix extraction of ports for connection hash calculation
- fix bond_xmit_broadcast return value when some devices are down
- phy: marvell: add Marvell specific PHY loopback
- sch_api: don't skip qdisc attach on ingress, prevent ref leak
- htb: restore minimal packet size handling in rate control
- sfp: fix high power modules without diagnostic monitoring
- mscc: ocelot:
- don't let phylink re-enable TX PAUSE on the NPI port
- don't dereference NULL pointers with shared tc filters
- smsc95xx: correct reset handling for LAN9514
- cpsw: avoid alignment faults by taking NET_IP_ALIGN into account
- phy: micrel: use kszphy_suspend/_resume for irq aware devices,
avoid races with the interrupt
Previous releases - always broken:
- xdp: check prog type before updating BPF link
- smc: resolve various races around abnormal connection termination
- sit: allow encapsulated IPv6 traffic to be delivered locally
- axienet: fix init/reset handling, add missing barriers, read the
right status words, stop queues correctly
- add missing dev_put() in sock_timestamping_bind_phc()
Misc:
- ipv4: prevent accidentally passing RTO_ONLINK to
ip_route_output_key_hash() by sanitizing flags
- ipv4: avoid quadratic behavior in netns dismantle
- stmmac: dwmac-oxnas: add support for OX810SE
- fsl: xgmac_mdio: add workaround for erratum A-009885"
* tag 'net-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (92 commits)
ipv4: add net_hash_mix() dispersion to fib_info_laddrhash keys
ipv4: avoid quadratic behavior in netns dismantle

net: phy: micrel: use kszphy_suspend()/kszphy_resume for irq aware devices
net: cpsw: avoid alignment faults by taking NET_IP_ALIGN into account
nfc: llcp: fix NULL error pointer dereference on sendmsg() after failed bind()
net: axienet: increase default TX ring size to 128
net: axienet: fix for TX busy handling
net: axienet: fix number of TX ring slots for available check
net: axienet: Fix TX ring slot available check
net: axienet: limit minimum TX ring size
net: axienet: add missing memory barriers
net: axienet: reset core on initialization prior to MDIO access
net: axienet: Wait for PhyRstCmplt after core reset
net: axienet: increase reset timeout
bpf, selftests: Add ringbuf memory type confusion test
