The virtual LBR test uses a python script to check the max size of
branch stack in the Intel-PT generated LBR. But it didn't check whether
python scripting is available (as it's optional).
Let's skip the test if the python support is not available.

Commit e0b23af82d ("perf list: Add PMU pai_crypto event
description for IBM z16") introduced the "Processor Activity
Instrumentation" for cryptographic counters for z16. The PMU device
driver exports the counters via sysfs files listed in directory
/sys/devices/pai_crypto.
To specify an event from that PMU, use 'perf stat -e pai_crypto/XXX/'.
However the JSON file mentioned in above commit exports the counter
decriptions in file pmu-events/arch/s390/cf_z16/pai.json. Rename this
file to pmu-events/arch/s390/cf_z16/pai_crypto.json to make the naming
consistent.
Now 'perf list' shows the counter names under pai_crypto section:
pai_crypto:
CRYPTO_ALL
[CRYPTO ALL. Unit: pai_crypto]
...
Output before was
pai:
CRYPTO_ALL
[CRYPTO ALL. Unit: pai_crypto]
...

During the transition to libbpf 1.0 some functions that perf used were
deprecated and finally removed from libbpf, so bpf_program__set_insns()
was introduced for perf to continue to use its bpf loader.
But when build with LIBBPF_DYNAMIC=1 we now need to check if that
function is available so that perf can build with older libbpf versions,
even if the end result is emitting a warning to the user that the use
of the perf BPF loader requires a newer libbpf, since bpf_program__set_insns()
touches libbpf objects internal state.
This affects only 'perf trace' when using bpf C code or pre-compiled
bytecode as an event.
Noticed on RHEL9, that has libbpf 0.7.0, where bpf_program__set_insns()
isn't available.

The bpf_load_program() prototype appeared in tools/lib/bpf/bpf.h as
deprecated, but nowadays its completely removed, so add it back for
building with the system libbpf when using 'make LIBBPF_DYNAMIC=1'.
This is a stop gap hack till we do like tools/bpf does with bpftool,
i.e. bootstrap the libbpf build and install it in the perf build
directory when not using 'make LIBBPF_DYNAMIC=1'.
That has to be done to all libraries in tools/lib/, so tha we can
remove -Itools/lib/ from the tools/perf CFLAGS.

Testcase stat_all_metrics.sh fails in powerpc:
90: perf all metrics test : FAILED!
The testcase "stat_all_metrics.sh" verifies perf stat result for all the
metric events present in perf list. It runs perf metric events with
various commands and expects non-empty metric result.
Incase of powerpc:hv-24x7 events, some of the event count can be 0 based
on system configuration. And if that event used as denominator in divide
equation, it can cause divide by 0 error. The current nest_metric.json
file creating divide by 0 issue for some of the metric events, which
results in failure of the "stat_all_metrics.sh" test case.
Most of the metrics events have cycles or an event which expect to have
a larger value as denominator, so adding 1 to the denominator of the
metric expression as a fix.
Result in powerpc box after this patch changes:
90: perf all metrics test : Ok

This is because at boot up, kernel text is writable, and there's no
reason to do tricks to updated it. But the verifier does not
distinguish updates at boot up and at run time, and causes a warning at
time of boot.
Add a check for system_state == SYSTEM_BOOTING and allow it if that is
the case.
[ These SYSTEM_BOOTING special cases are all pretty horrid, but the x86
text_poke() code does some odd things at bootup, forcing this for now

This pull request contains a commit that fixes bf95b2bc3e ("rcu: Switch
polled grace-period APIs to ->gp_seq_polled"), which could incorrectly
leave interrupts enabled after an early-boot call to synchronize_rcu().
Such synchronize_rcu() calls must acquire leaf rcu_node locks in order to
properly interact with polled grace periods, but the code did not take
into account the possibility of synchronize_rcu() being invoked from
the portion of the boot sequence during which interrupts are disabled.
This commit therefore switches the lock acquisition and release from

Pull RCU fix from Paul McKenney:
"Fix a regression caused by commit bf95b2bc3e ("rcu: Switch polled
grace-period APIs to ->gp_seq_polled"), which could incorrectly leave
interrupts enabled after an early-boot call to synchronize_rcu().
Such synchronize_rcu() calls must acquire leaf rcu_node locks in order
to properly interact with polled grace periods, but the code did not
take into account the possibility of synchronize_rcu() being invoked
from the portion of the boot sequence during which interrupts are
disabled.
This commit therefore switches the lock acquisition and release from
irq to irqsave/irqrestore"

As Shakeel explains the commit under Fixes had the unintended
side-effect of no longer pre-loading the cached memory allowance.
Even tho we previously dropped the first packet received when
over memory limit - the consecutive ones would get thru by using
the cache. The charging was happening in batches of 128kB, so
we'd let in 128kB (truesize) worth of packets per one drop.
After the change we no longer force charge, there will be no
cache filling side effects. This causes significant drops and
connection stalls for workloads which use a lot of page cache,
since we can't reclaim page cache under GFP_NOWAIT.
Some of the latency can be recovered by improving SACK reneg
handling but nowhere near enough to get back to the pre-5.15
performance (the application I'm experimenting with still
sees 5-10x worst latency).
Apply the suggested workaround of using GFP_ATOMIC. We will now
be more permissive than previously as we'll drop _no_ packets
in softirq when under pressure. But I can't think of any good
and simple way to address that within networking.

This commit fixes a bug that can cause a TCP data sender to repeatedly
defer RTOs when encountering SACK reneging.
The bug is that when we're in fast recovery in a scenario with SACK
reneging, every time we get an ACK we call tcp_check_sack_reneging()
and it can note the apparent SACK reneging and rearm the RTO timer for
srtt/2 into the future. In some SACK reneging scenarios that can
happen repeatedly until the receive window fills up, at which point
the sender can't send any more, the ACKs stop arriving, and the RTO
fires at srtt/2 after the last ACK. But that can take far too long
(O(10 secs)), since the connection is stuck in fast recovery with a
low cwnd that cannot grow beyond ssthresh, even if more bandwidth is
available.
This fix changes the logic in tcp_check_sack_reneging() to only rearm
the RTO timer if data is cumulatively ACKed, indicating forward
progress. This avoids this kind of nearly infinite loop of RTO timer
re-arming. In addition, this meets the goals of
tcp_check_sack_reneging() in handling Windows TCP behavior that looks
temporarily like SACK reneging but is not really.
Many thanks to Jakub Kicinski and Neil Spring, who reported this issue
and provided critical packet traces that enabled root-causing this
issue. Also, many thanks to Jakub Kicinski for testing this fix.

ops->init() fails, data is released. However, the ptr pointer in
net->gen is invalid. In this case, when nfqnl_nf_hook_drop() is invoked
to release the net, invalid address access occurs.
The process is as follows:
setup_net()
ops_init()
data = kzalloc(...) ---> alloc "data"
net_assign_generic() ---> assign "date" to ptr in net->gen
...
ops->init() ---> failed
...
kfree(data); ---> ptr in net->gen is invalid

get validation of how important their work is internally, especially

Before 262f2b782e ("net: fman: Map the base address once"), the
physical address of the MAC was exposed to userspace in two places: via
sysfs and via SIOCGIFMAP. While this is not best practice, it is an
external ABI which is in use by userspace software.
The aforementioned commit inadvertently modified these addresses and
made them virtual. This constitutes and ABI break. Additionally, it
leaks the kernel's memory layout to userspace. Partially revert that
commit, reintroducing the resource back into struct mac_device, while
keeping the intended changes (the rework of the address mapping).

For apollolake the mapping between LEDs and GPIO pins was off because of
a refactoring when we introduced a new device model.
In addition to the reordering the indices in the lookup table need to be
updated as well.

commit b0c07116c8 ("platform/x86: amd-pmc: Avoid reading SMU version at
probe time") adjusted the behavior for amd-pmc to avoid reading the SMU
version at startup but rather on first use to improve boot time.
However the SMU version is also used to decide whether to place a timer
based wakeup in the OS_HINT message. If the idlemask hasn't been read
before this message was sent then the SMU version will not have been
cached.
Ensure the SMU version has been read before deciding whether or not to
run this codepath.

NIC is stopped with rtnl_lock held, and during the stop it cancels the
'service_task' work and free irqs.
However, if CONFIG_MACSEC is set, rtnl_lock is acquired both from
aq_nic_service_task and aq_linkstate_threaded_isr. Then a deadlock
happens if aq_nic_stop tries to cancel/disable them when they've already
started their execution.
As the deadlock is caused by rtnl_lock, it causes many other processes
to stall, not only atlantic related stuff.
Fix it by introducing a mutex that protects each NIC's macsec related
data, and locking it instead of the rtnl_lock from the service task and
the threaded IRQ.
Before this patch, all macsec data was protected with rtnl_lock, but
maybe not all of it needs to be protected. With this new mutex, further
efforts can be made to limit the protected data only to that which
requires it. However, probably it doesn't worth it because all macsec's
data accesses are infrequent, and almost all are done from macsec_ops
or ethtool callbacks, called holding rtnl_lock, so macsec_mutex won't
never be much contended.
The issue appeared repeteadly attaching and deattaching the NIC to a
bond interface. Doing that after this patch I cannot reproduce the bug.
