The version generated by perf may not be correct by just changing the
head commit, like this:
$ git log --pretty=format:"%H" -n 1

$ perf -v
perf version 5.16.gb5d9d4708a24
$ git reset --hard HEAD^
HEAD is now at 629f520b265f
$ make
...
$ ./perf -v
perf version 5.16.gb5d9d4708a24
The dependency to building PERF-VERSION-FILE should also include ORIG_HEAD,
as this changes when changing the head commit (while HEAD does not).

The test creates a separate VRF for the VLAN upper, but does not destroy
it during cleanup, resulting in "RTNETLINK answers: File exists" errors.
Fix by using the same VRF for the port and its VLAN upper. This is OK
since their IP addresses do not overlap.

Compiled with clang by adding LLVM=1 both kernel and selftests/bpf
build, I hit the following compilation error:
In file included from /.../tools/testing/selftests/bpf/prog_tests/subskeleton.c:6:
./test_subskeleton_lib.subskel.h:168:6: error: variable 'err' is used uninitialized whenever
'if' condition is true [-Werror,-Wsometimes-uninitialized]

errno = -err;
^~~
./test_subskeleton_lib.subskel.h:168:2: note: remove the 'if' if its condition is always false
if (!s->progs)
^~~~~~~~~~~~~~
The compilation error is triggered by the following code
...
int err;
obj = (struct test_subskeleton_lib *)calloc(1, sizeof(*obj));
if (!obj) {
errno = ENOMEM;
goto err;
}
...
err:
test_subskeleton_lib__destroy(obj);
errno = -err;
...
in test_subskeleton_lib__open(). The 'err' is not initialized, yet it
is used in 'errno = -err' later.
The fix is to remove 'errno = -err' since errno has been set properly
in all incoming branches.

tools/memory-model: Explain syntactic and semantic dependencies
Add a shell script to check that the call-graphs generated using frame
pointers (--call-graph fp) are complete and not missing leaf functions:
| $ perf test 88 -v
| 88: Check Arm64 callgraphs are complete in fp mode :
| --- start ---
| test child forked, pid 8734
| + Compiling test program (/tmp/test_program.Cz3yL)...
| + Recording (PID=8749)...
| + Stopping perf-record...
| test_program.Cz
| 728 leaf
| 753 parent
| 76c main
| test child finished with 0
| ---- end ----
| Check Arm SPE callgraphs are complete in fp mode: Ok
It's supposed to work with both unwinders:
| $ make # for libunwind (default)
| $ make NO_LIBUNWIND=1 # for libdw
Tester notes:
Ran it on N1SDP and it passes, and it fails if b9f6fbb3b2c29736 ("perf
arm64: Inject missing frames when using 'perf record --call-graph=fp'")
isn't applied.

- Simplify the PASID handling to allocate the PASID once, associate it to

Pull tpm updates from Jarkko Sakkinen:
"In order to split the work a bit we've aligned with David Howells more
or less that I take more hardware/firmware aligned keyring patches,
and he takes care more of the framework aligned patches.
For TPM the patches worth of highlighting are the fixes for
refcounting provided by Lino Sanfilippo and James Bottomley.
Eric B. has done a bunch obvious (but important) fixes but there's one
a bit controversial: removal of asym_tpm. It was added in 2018 when
TPM1 was already declared as insecure and world had moved on to TPM2.
I don't know how this has passed all the filters but I did not have a
chance to see the patches when they were out. I simply cannot commit
to maintaining this because it was from all angles just wrong to take
it in the first place to the mainline kernel. Nobody should use this
module really for anything.
Finally, there is a new keyring '.machine' to hold MOK keys ('Machine
Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be
set, from which kernel knows that MOK keys are kernel trusted keys and
they are populated to the machine keyring. This keyring linked to the
secondary trusted keyring, which means that can be used like any
kernel trusted keys. This keyring of course can be used to hold other
MOK'ish keys in other platforms in future"

When test_lirc_mode2_user exec failed, the test report failed but still
exit with 0. Fix it by exiting with an error code.
Another issue is for the LIRCDEV checking. With bash -n, we need to quote
the variable, or it will always be true. So if test_lirc_mode2_user was
not run, just exit with skip code.

The context access converter rewrites the 4-byte load from
bpf_sk_lookup->remote_port to a 2-byte load from bpf_sk_lookup_kern
structure.
It means that we cannot treat the destination register contents as a 32-bit
value, or the code will not be portable across big- and little-endian
architectures.
This is exactly the same case as with 4-byte loads from bpf_sock->dst_port
so follow the approach outlined in [1] and treat the register contents as a
16-bit value in the test.

In commit 9a69e2b385f4 ("bpf: Make remote_port field in struct
bpf_sk_lookup 16-bit wide") ->remote_port field changed from __u32 to
__be16.
However, narrow load tests which exercise 1-byte sized loads from
offsetof(struct bpf_sk_lookup, remote_port) were not adopted to reflect the
change.
As a result, on little-endian we continue testing loads from addresses:
- (__u8 *)&ctx->remote_port + 3
- (__u8 *)&ctx->remote_port + 4
which map to the zero padding following the remote_port field, and don't
break the tests because there is no observable change.
While on big-endian, we observe breakage because tests expect to see zeros
for values loaded from:
- (__u8 *)&ctx->remote_port - 1
- (__u8 *)&ctx->remote_port - 2
Above addresses map to ->remote_ip6 field, which precedes ->remote_port,
and are populated during the bpf_sk_lookup IPv6 tests.
Unsurprisingly, on s390x we observe:
#136/38 sk_lookup/narrow access to ctx v4:OK
#136/39 sk_lookup/narrow access to ctx v6:FAIL
Fix it by removing the checks for 1-byte loads from offsets outside of the
->remote_port field.

Before this patch, the symbol end address fixup to be called, needed two
conditions being met:
if (prev->end == prev->start && prev->end != curr->start)
Where
"prev->end == prev->start" means that prev is zero-long
(and thus needs a fixup)
and
"prev->end != curr->start" means that fixup hasn't been applied yet
However, this logic is incorrect in the following situation:
*curr = {rb_node = {__rb_parent_color = 278218928,
rb_right = 0x0, rb_left = 0x0},
start = 0xc000000000062354,
end = 0xc000000000062354, namelen = 40, type = 2 '\002',
binding = 0 '\000', idle = 0 '\000', ignore = 0 '\000',
inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false,
name = 0x1159739e "kprobe_optinsn_page\t[__builtin__kprobes]"}
*prev = {rb_node = {__rb_parent_color = 278219041,
rb_right = 0x109548b0, rb_left = 0x109547c0},
start = 0xc000000000062354,
end = 0xc000000000062354, namelen = 12, type = 2 '\002',
binding = 1 '\001', idle = 0 '\000', ignore = 0 '\000',
inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false,
name = 0x1095486e "optinsn_slot"}
In this case, prev->start == prev->end == curr->start == curr->end,
thus the condition above thinks that "we need a fixup due to zero
length of prev symbol, but it has been probably done, since the
prev->end == curr->start", which is wrong.
After the patch, the execution path proceeds to arch__symbols__fixup_end
function which fixes up the size of prev symbol by adding page_size to
its end offset.

Add two tests to pmtu.sh, for verifying that PMTU exceptions get
properly created for routes that don't belong to the main table.
A fib-rule based on the packet's DSCP field is used to jump to the
correct table. ECN shouldn't interfere with this process, so each test
has two components: one that only sets DSCP and one that sets both DSCP
and ECN.
One of the test triggers PMTU exceptions using ICMP Echo Requests, the
other using UDP packets (to test different handlers in the kernel).
A few adjustments are necessary in the rest of the script to allow
policy routing scenarios:
* Add global variable rt_table that allows setup_routing_*() to
add routes to a specific routing table. By default rt_table is set
to "main", so existing tests don't need to be modified.
* Another global variable, policy_mark, is used to define which
dsfield value is used for policy routing. This variable has no
effect on tests that don't use policy routing.
* The UDP version of the test uses socat. So cleanup() now also need
to kill socat PIDs.
* route_get_dst_pmtu_from_exception() and route_get_dst_exception()
now take an optional third argument specifying the dsfield. If
not specified, 0 is used, so existing users don't need to be
modified.

flying in both directions, from the client to the server, and in reverse

Recently added dst_port check relies on the fact that destination

of time. This holds true only for the client socket, which connects to the

The commit 314001f0bf92 ("af_unix: Add OOB support") introduced OOB for
AF_UNIX, but it lacks some changes for POLLPRI. Let's add the missing
piece.
In the selftest, normal datagrams are sent followed by OOB data, so this
commit replaces `POLLIN | POLLPRI` with just `POLLPRI` in the first test
case.

This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.
Features
* adi,adf4350
- Switch from of specific to generic device properties enabling use with
other firmware types.
* adi,adx345
- Switch from of specific to generic device properties.
- Add ACPI ID ADS0345

- Apply a scale of 1 when no scale is provided.
- Make best effort to establish a valid offset value for fractional
cases.

This patch changes the selftests/bpf Makefile to also generate
a subskel.h for every skel.h it would have normally generated.
Separately, it also introduces a new subskeleton test which tests
library objects, externs, weak symbols, kconfigs, and user maps.
