Libraries should be listed last on the compiler's command line, so that
the linker can look for and find still unresolved symbols. The librt
library, required for the shm_* functions, was announced using CFLAGS,
which puts the library *before* the source files, and fails compilation
on my system:
======================
gcc -isystem /src/linux-selftests/usr/include -Wall -lrt test_cachestat.c
-o /src/linux-selftests/kselftest/cachestat/test_cachestat
/usr/bin/ld: /tmp/cceQWO3u.o: in function `test_cachestat_shmem':

collect2: error: ld returned 1 exit status
make[4]: *** [../lib.mk:181: /src/linux-selftests/kselftest/cachestat/test_cachestat] Error 1
======================
Announce the library using the LDLIBS variable, which ensures the proper
ordering on the command line.

Observed occassional failures in the futex_wait_timeout test:
ok 1 futex_wait relative succeeds
ok 2 futex_wait_bitset realtime succeeds
ok 3 futex_wait_bitset monotonic succeeds
ok 4 futex_wait_requeue_pi realtime succeeds
ok 5 futex_wait_requeue_pi monotonic succeeds
not ok 6 futex_lock_pi realtime returned 0
......
The test expects the child thread to complete some steps before
the parent thread gets to run. There is an implicit expectation
of the order of invocation of futex_lock_pi between the child thread
and the parent thread. Make this order explicit. If the order is
not met, the futex_lock_pi call in the parent thread succeeds and
will not timeout.

Objtool --rethunk does two things:
- it collects all (tail) call's of __x86_return_thunk and places them
into .return_sites. These are typically compiler generated, but
RET also emits this same.
- it fudges the validation of the __x86_return_thunk symbol; because
this symbol is inside another instruction, it can't actually find
the instruction pointed to by the symbol offset and gets upset.
Because these two things pertained to the same symbol, there was no
pressing need to separate these two separate things.
However, alas, along comes SRSO and more crazy things to deal with
appeared.
The SRSO patch itself added the following symbol names to identify as
rethunk:
'srso_untrain_ret', 'srso_safe_ret' and '__ret'
Where '__ret' is the old retbleed return thunk, 'srso_safe_ret' is a
new similarly embedded return thunk, and 'srso_untrain_ret' is
completely unrelated to anything the above does (and was only included
because of that INT3 vs UD2 issue fixed previous).
Clear things up by adding a second category for the embedded instruction
thing.

This selftest is designed for testing the support of NEXT-C-SID flavor
for SRv6 End.X behavior. It instantiates a virtual network composed of
several nodes: hosts and SRv6 routers. Each node is realized using a
network namespace that is properly interconnected to others through veth
pairs, according to the topology depicted in the selftest script file.
The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged
by hosts for communicating with each other. Such routers i) apply
different SRv6 Policies to the traffic received from connected hosts,
considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID
compression mechanism for encoding several SRv6 segments within a single
128-bit SID address, referred to as a Compressed SID (C-SID) container.
The NEXT-C-SID is provided as a "flavor" of the SRv6 End.X behavior,
enabling it to properly process the C-SID containers. The correct
execution of the enabled NEXT-C-SID SRv6 End.X behavior is verified
through reachability tests carried out between hosts belonging to the
same VPN.

This test verifies whether the encapsulated packets have the correct
configured TTL. It does so by sending ICMP packets through the test
topology and mirroring them to a gretap netdevice. On a busy host
however, more than just the test ICMP packets may end up flowing
through the topology, get mirrored, and counted. This leads to
potential spurious failures as the test observes much more mirrored
packets than the sent test packets, and assumes a bug.
Fix this by tightening up the mirror action match. Change it from
matchall to a flower classifier matching on ICMP packets specifically.

retpolines and IBT
The kprobes optimization check can_optimize() calls
insn_is_indirect_jump() to detect indirect jump instructions in
a target function. If any is found, creating an optprobe is disallowed
in the function because the jump could be from a jump table and could
potentially land in the middle of the target optprobe.
With retpolines, insn_is_indirect_jump() additionally looks for calls to
indirect thunks which the compiler potentially used to replace original
jumps. This extra check is however unnecessary because jump tables are
disabled when the kernel is built with retpolines. The same is currently
the case with IBT.
Based on this observation, remove the logic to look for calls to
indirect thunks and skip the check for indirect jumps altogether if the
kernel is built with retpolines or IBT. Remove subsequently the symbols
__indirect_thunk_start and __indirect_thunk_end which are no longer
needed.
Dropping this logic indirectly fixes a problem where the range
[__indirect_thunk_start, __indirect_thunk_end] wrongly included also the
return thunk. It caused that machines which used the return thunk as
a mitigation and didn't have it patched by any alternative ended up not
being able to use optprobes in any regular function.

The linker script arch/x86/kernel/vmlinux.lds.S matches the thunk
sections ".text.__x86.*" from arch/x86/lib/retpoline.S as follows:
.text {
[...]
TEXT_TEXT
[...]
__indirect_thunk_start = .;
*(.text.__x86.*)
__indirect_thunk_end = .;
[...]
}
Macro TEXT_TEXT references TEXT_MAIN which normally expands to only
".text". However, with CONFIG_LTO_CLANG, TEXT_MAIN becomes
".text .text.[0-9a-zA-Z_]*" which wrongly matches also the thunk
sections. The output layout is then different than expected. For
instance, the currently defined range [__indirect_thunk_start,
__indirect_thunk_end] becomes empty.
Prevent the problem by using ".." as the first separator, for example,
".text..__x86.indirect_thunk". This pattern is utilized by other
explicit section names which start with one of the standard prefixes,
such as ".text" or ".data", and that need to be individually selected in
the linker script.

From: Eric Garver <[email protected]>
This adds an explicit drop action. This is used by OVS to drop packets
for which it cannot determine what to do. An explicit action in the
kernel allows passing the reason _why_ the packet is being dropped or
zero to indicate no particular error happened (i.e: OVS intentionally
dropped the packet).
Since the error codes coming from userspace mean nothing for the kernel,
we squash all of them into only two drop reasons:
- OVS_DROP_EXPLICIT_WITH_ERROR to indicate a non-zero value was passed
- OVS_DROP_EXPLICIT to indicate a zero value was passed (no error)
e.g. trace all OVS dropped skbs
# perf trace -e skb:kfree_skb --filter="reason >= 0x30000"
[..]
106.023 ping/2465 skb:kfree_skb(skbaddr: 0xffffa0e8765f2000, \
location:0xffffffffc0d9b462, protocol: 2048, reason: 196611)
reason: 196611 --> 0x30003 (OVS_DROP_EXPLICIT)
Also, this patch allows ovs-dpctl.py to add explicit drop actions as:
"drop" -> implicit empty-action drop
"drop(0)" -> explicit non-error action drop
"drop(42)" -> explicit error action drop

* adi,ad8366
- Add support for the HMC792 digital attenuator (mostly chip specific data)
* alwinner,sun20i-gpadc
- New driver for the integrated ADC on a number of allwinner SoCs
including dt-binding documentation.
* microchip,mcp4728
- New driver for this quad channel DAC. Includes dt-bindings.
* miramems, da280
- Add ID for DA217 accelerometer which is compatible with the da280.
* murata,irs-d200
- New driver for this passive infrared sensor typically used for human
detection. Includes bindings and a few pieces of new ABI to
cover a case of needing to count a number of repeats of an event
before reporting it.
* rohm,bu27008
- Add initial support for the BU27010 RGB + flickering sensor to this
driver. Substantial refactoring was needed to enable this.
Features
* adi,admv8818
- Add mode that bypasses the input and output filters.
* amlogic,meson
- Support control of the MUX on channel 7, exposed as multiple channels.
- Support channel labels.
* sensirion,scd4x
- Add pressure compensation. Controlled via an 'output' pressure channel.
* ti,lmp92040
- Add IIO buffered supported (read via chrdev).
* vishay,vcnl4000
- Add proximity interrupt support for vcnl4200.
- Add proximity integration time control for vcnl4200.
- Add illuminance integration time control for vcnl4040 and vcnl4200.
- Add calibration bias, proximity and illuminance event period, and
oversampling ratio control for vcnl4040 and vncl4200.
Cleanup and minor fixes
* core
- Tidy up handling of set_trigger_state() callback return values
to consistently assume no positive return values.
- Use min() rather than min_t() in a case where types were clearly
the same.
- Drop some else statements that follow continue with a loop or
a returns.
- White space and comment format cleanup.
- Use sysfs_match_string() helper to improve readability.
- Use krealloc_array() to make it explicit a krealloc is for an array
of structures, not just one.
* tools
- Tidy up potential overflow in array index.
* tree wide
- Fix up includes for DT related headers.
- Drop some error prints in places where as similar error message
is printed by the function being called.
- Tidy up handling of return value from platform_get_irq() to no longer
take into account 0 as a value that might be returned. Similar for
fwnode_irq_get().
* adi,ad7192
- Add missing error check and improved debug logging.
- Use sysfs_emit_at() rather than open coded variant.
* adi,adis16475
- Drop unused scan element enum entries.
- Specify that a few more devices support burst32 mode.
* adi,admv1013
- Enable all required regulators and document as required in the
dt-binding.
* adi,admv1014
- Make all regulators required in the dt-binding as the device needs
them all enabled.
* adi,adxl313
- Fix wrong enum values being used in the i2c_device_id table.
- Use i2c_get_match_data() to reduce open coded handling of the
various id tables.
* allwinner,gpadc
- Make the kconfig text more specific to make space for separate drivers
for other Allwinner devices.
* amlogic,meson
- Drop unused timestamp channels as no buffer support.
- Various minor reorganizations to enable addition of support channel 7
MUX.
- Initialize some default values to account for potential previous user
since reboot.
* qcom,spmi-adc5
- Add ADC5_GPIO2_100K_PU support to driver to line up with bindings.
* qcom,spmi-adc7
- Use predefined channel ID definitions rather than values.
* invensense, common
- Factor out the timestamp handling to a module used by both mpu6050 and
icm42600.
* invensense,mpu6050
- Read as many FIFO elements as possible in one bus access.
* men,s188
- Drop redundant initialization of driver owner field.
* microchip,mcp4018 and mcp4531
- Use i2c_get_match_data() instead of open coding. Includes making the
data format the same for the i2c_device_id and firmware match
tables.
* semtech,sx9310
- dt-bindings: Add reference to IIO schema to provide the label property.
* semtech,sx9324
- dt-bindings: Add reference to IIO schema to provide the label property.
* st,stm32-adc
- Use devm_platform_get_and_ioremap_resource() instead of open coded
version.
* st,stm-lptimer-trigger
- Drop setting platform drvdata as it wasn't then used.
* ti,ads1015
- Fix wrong dt binding description of ti,datarate for some devices.
* vishay,vcnl4200
- Move to switch statements for channel type checking to make later
additions simpler.

Our ABI opts to provide future proofing by defining a much larger
SVE_VQ_MAX than the architecture actually supports. Since we use
this define to control the size of our vector data buffers this results
in a lot of overhead when we initialise which can be a very noticable
problem in emulation, we fill buffers that are orders of magnitude
larger than we will ever actually use even with virtual platforms that
provide the full range of architecturally supported vector lengths.
Define and use the actual architecture maximum to mitigate this.

Add the LSE and various features check in the set of hwcap tests.
As stated in the ARM manual, the LSE2 feature allows for atomic access
to unaligned memory. Therefore, for processors that only have the LSE
feature, we register .sigbus_fn to test their ability to perform
unaligned access.

Some enhanced features, such as the LSE2 feature, do not result in
SILLILL if LSE2 is missing and LSE is present, but will generate a
SIGBUS exception when atomic access unaligned.
Therefore, we add test item to test this type of features.
Notice that testing for SIGBUS only makes sense after make sure that
the instruction does not cause a SIGILL signal.

Add macro definition functions DEF_SIGHANDLER_FUNC() and
DEF_INST_RAISE_SIG() helpers.
Furthermore, there is no need to modify the default SIGILL handling
function throughout the entire testing lifecycle in the main() function.
It is reasonable to narrow the scope to the context of the sig_fn
function only.
This is a pre-patch for the subsequent SIGBUS handler patch.

Tests that were expecting a signal were not correctly checking for a
SKIP condition. Move the check before the signal checking when
processing test result.

The main changes are:
1) Fix array-index-out-of-bounds access when detaching from an
already empty mprog entry from Daniel Borkmann.
2) Adjust bpf selftest because of a recent llvm change
related to the cpu-v4 ISA from Eduard Zingerman.
3) Add uprobe support for the bpf_get_func_ip helper from Jiri Olsa.
4) Fix a KASAN splat due to the kernel incorrectly accepted
an invalid program using the recent cpu-v4 instruction from
Yonghong Song.
