On anARM machine, kernel symbols from modules can be resolved to $a
instead of printing the actual symbol name. Ignore symbols starting with
"$" when building kallsyms rbtree.
A sample stacktrace is shown as follows:
c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms])
bf4a66d8 $a+0x78 ([test_module])
c0a4f5f4 kthread+0x15c ([kernel.kallsyms])
c0a001f8 ret_from_fork+0x14 ([kernel.kallsyms])
On an ARM machine, $a/$d symbols are used by the compiler to mark the
beginning of code/data part in code section. These symbols are filtered
out when linking vmlinux(see scripts/kallsyms.c ignored_prefixes), but
are left on modules. So there are $a symbols in /proc/kallsyms which
share the same addresses with the actual module symbols and confuses
perf when resolving symbols.
After this patch, the module symbol name is printed:
c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms])
bf4a66d8 test_func+0x78 ([test_module])
c0a4f5f4 kthread+0x15c ([kernel.kallsyms])

Perf tool sets exclude_guest by default while calling perf_event_open().
Because IBS does not have filtering capability, it always gets rejected
by IBS PMU driver and thus perf falls back to non-precise sampling. Fix
it by not setting exclude_guest by default on AMD.
Before:
$ sudo ./perf record -C 0 -vvv true |& grep precise
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
decreasing precise_ip by one (1)
precise_ip 1
decreasing precise_ip by one (0)
After:
$ sudo ./perf record -C 0 -vvv true |& grep precise
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
Committer notes:
Fixup init to zero for perf_env in older compilers:
arch/x86/util/evsel.c:15:26: error: missing field 'os_release' initializer [-Werror,-Wmissing-field-initializers]
struct perf_env env = {0};
^
Committer notes:
Namhyung remarked:
It'd be nice if it can cover explicit "-e cycles:pp" as well.
Ravi clarified:
For explicit :pp modifier, evsel->precise_max does not get set and thus perf
does not try with different attr->precise_ip values while exclude_guest set.
So no issue with explicit :pp:
$ sudo ./perf record -C 0 -e cycles:pp -vvv |& grep "precise_ip\|exclude_guest"
precise_ip 2
exclude_guest 1
precise_ip 2
exclude_guest 1
switching off exclude_guest, exclude_host
precise_ip 2
^C
Also, with :P modifier, evsel->precise_max gets set but exclude_guest does
not and thus :P also works fine:
$ sudo ./perf record -C 0 -e cycles:P -vvv |& grep "precise_ip\|exclude_guest"
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
^C

The current logic for the perf missing feature has a bug that it can
wrongly clear some modifiers like G or H. Actually some PMUs don't
support any filtering or exclusion while others do. But we check it as
a global feature.
For example, the cycles event can have 'G' modifier to enable it only in
the guest mode on x86. When you don't run any VMs it'll return 0.
# perf stat -a -e cycles:G sleep 1
Performance counter stats for 'system wide':
0 cycles:G
1.000721670 seconds time elapsed
But when it's used with other pmu events that don't support G modifier,
it'll be reset and return non-zero values.
# perf stat -a -e cycles:G,msr/tsc/ sleep 1
Performance counter stats for 'system wide':
538,029,960 cycles:G
16,924,010,738 msr/tsc/
1.001815327 seconds time elapsed
This is because of the missing feature detection logic being global.
Add a hashmap to set pmu-specific exclude_host/guest features.
Committer notes:
Fix 'perf test python' by adding a stub for evsel__find_pmu() in
tools/perf/util/python.c, document that it is used so far only for the
above reasons so that if anybody needs this in the python binding
usecases, we can revisit this.

Here is the big set of staging driver updates and cleanups for 5.16-rc1.
Overall we ended up removing a lot of code this time, a bit over 20,000
lines are now gone thanks to a lot of cleanup work by many developers.
Nothing huge in here functionality wise, just loads of cleanups:
- r8188eu driver major cleanups and removal of unused and dead
code
- wlan-ng minor cleanups
- fbtft driver cleanups
- most driver cleanups
- rtl8* drivers cleanups
- rts5208 driver cleanups
- vt6655 driver cleanups
- vc04_services drivers cleanups
- wfx cleanups on the way to almost getting this merged out of
staging (it's close!)
- tiny mips changes needed for the mt7621 drivers, they have
been acked by the respective subsystem maintainers to go
through this tree.
All of these have been in linux-next for a while with no reported
issues.

20,000 lines are now gone thanks to a lot of cleanup work by many
developers.
Nothing huge in here functionality wise, just loads of cleanups:
- r8188eu driver major cleanups and removal of unused and dead code
- wlan-ng minor cleanups
- fbtft driver cleanups
- most driver cleanups
- rtl8* drivers cleanups
- rts5208 driver cleanups
- vt6655 driver cleanups
- vc04_services drivers cleanups
- wfx cleanups on the way to almost getting this merged out of
staging (it's close!)
- tiny mips changes needed for the mt7621 drivers, they have been
acked by the respective subsystem maintainers to go through this
tree.
All of these have been in linux-next for a while with no reported
issues"

In commit 2214c0e772 ("parisc: Move thread_info into task struct")
PA-RISC gained support for THREAD_INFO_IN_TASK while changes were
already underway to keep the CPU field in thread_info rather than move
it into task_struct when THREAD_INFO_IN_TASK is enabled. The result is a
broken build for all PA-RISC configs that enable SMP.
So let's partially revert that commit, and get rid of the ugly hack to
get at the offset of task_struct::cpu without having to include
linux/sched.h, and put the CPU field back where it was before.

I no longer think interrupts can be disabled in the futex and cmpxchg
operations because of COW breaks. This not ideal but I suspect it's the
best we can do.
For the cmpxchg operations in syscall.S, we rely on the code to not
schedule off the gateway page. For the futex, I added code to disable
preemption.
So far, I haven't seen the warnings with the attached change but the
change is only lightly tested.

If the previous context had interrupts disabled, we should better
keep them disabled. This was noticed in the unwinding code where
a copy_from_kernel_nofault() triggered a page fault, and after
the fixup by the page fault handler interrupts where suddenly
enabled.

These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

This is a rather large update for the ARM devicetree files, after a few
quieter releases, with 775 total commits and 47 branches pulled into
this one. There are 5 new SoC types plus some minor variations, and
a total of 60 new machines, so I'm limiting the summary to the main
noteworthy items:
- Apple M1 gain support for PCI and pinctrl, getting a bit
closer to a usable system out of the box.
- Qualcomm gains support for Snapdragon 690 (aka SM6350) as
well as SM7225, 11 new smartphones, and three additional
Chromebooks, and improvements all over the place.
- Samsung gains support for ExynosAutov9, an automotive version
of their smartphone SoC, but otherwise no major changes.
- Microchip adds the SAMA5D29 SoC in the SAMA5 family, and a
number of improvements for the recently added SAMA7 family.
The LAN966 SoC that was added in the platform code does not
have dts files yet. Two board files are added for the older
at91sam9g20 SoC
- Aspeed supports two additional server boards using their AST2600
as BMC, and improves support for qemu models
- Rockchip RK3566/RK3688 gets added, along with six new
development boards using RK3328/RK3399/RK3566, and one
Chromebook tablet.

is notably less than their usual additions, but they also gain
improvements to their many existing boards
- STmicroelectronics adds their stm32mp13 SoC family along with
a reference board
- Renesas adds new versions of their R-Car Gen3 SoCs and many
updates for their older generations
- Broadcom adds support for a number of Cisco Meraki wireless

Pull ARM SoC DT updates from Arnd Bergmann:
"This is a rather large update for the ARM devicetree files, after a
few quieter releases, with 775 total commits and 47 branches pulled
into this one.
There are 5 new SoC types plus some minor variations, and a total of
60 new machines, so I'm limiting the summary to the main noteworthy
items:
- Apple M1 gain support for PCI and pinctrl, getting a bit closer to
a usable system out of the box.
- Qualcomm gains support for Snapdragon 690 (aka SM6350) as well as
SM7225, 11 new smartphones, and three additional Chromebooks, and
improvements all over the place.
- Samsung gains support for ExynosAutov9, an automotive version of
their smartphone SoC, but otherwise no major changes.
- Microchip adds the SAMA5D29 SoC in the SAMA5 family, and a number
of improvements for the recently added SAMA7 family. The LAN966 SoC
that was added in the platform code does not have dts files yet.
Two board files are added for the older at91sam9g20 SoC
- Aspeed supports two additional server boards using their AST2600 as
BMC, and improves support for qemu models
- Rockchip RK3566/RK3688 gets added, along with six new development
boards using RK3328/RK3399/RK3566, and one Chromebook tablet.
- Two NAS boxes are added using the ARMv4 based Gemini platform
- One new board is added to the Intel Arria SoC FPGA family
- Marvell adds one network switch based on Armada 381 and the new
MOCHAbin 7040 development board
- NXP adds support for the S32G2 automotive SoC, two imx6 based ebook
readers, and three additional development boards, which is notably
less than their usual additions, but they also gain improvements to
their many existing boards
- STmicroelectronics adds their stm32mp13 SoC family along with a
reference board
- Renesas adds new versions of their R-Car Gen3 SoCs and many updates
for their older generations
- Broadcom adds support for a number of Cisco Meraki wireless
controllers, along with two new boards and other updates for
BCM53xx/BCM47xx networking SoCs and the Raspberry Pi boards
- Mediatek improves support for the MT81xx SoCs used in Chromebooks
as well as the MT76xx networking SoCs
- NVIDIA adds a number of cleanups and additional support for more
hardware on the already supported machines
- TI K3 adds support for three new boards along with cleanups
- Toshiba adds one board for the Visconti family
- Xilinx adds five new ZynqMP based machines
- Amlogic support is added for the Radxa Zero and two Jethub home
automation controllers, along with changes to other machines
- Rob Herring continues his work on fixing dtc warnings all over the
tree.
- Minor updates for TI OMAP, Mstar, Allwinner/sunxi, Hisilicon,
Ux500, Unisoc"

The SoC updates this time are mainly removing obsolete code from the
OMAP2 platform, another step in the eternal cleanup of that platform.
There are two new SoCs getting added: STMicroelectronics stm32mp13 and
Microchip lan966. Both fit into existing platforms and require minimal
changes here.
A couple of MAINTAINER file updates relate to those changes, and
update some file paths.

Pull per signal_struct coredumps from Eric Biederman:
"Current coredumps are mixed up with the exit code, the signal handling
code, and the ptrace code making coredumps much more complicated than
necessary and difficult to follow.
This series of changes starts with ptrace_stop and cleans it up,
making it easier to follow what is happening in ptrace_stop. Then
cleans up the exec interactions with coredumps. Then cleans up the
coredump interactions with exit. Finally the coredump interactions
with the signal handling code is cleaned up.
The first and last changes are bug fixes for minor bugs.
I believe the fact that vfork followed by execve can kill the process
the called vfork if exec fails is sufficient justification to change
the userspace visible behavior.
In previous discussions some of these changes were organized
differently and individually appeared to make the code base worse. As
currently written I believe they all stand on their own as cleanups
and bug fixes.
Which means that even if the worst should happen and the last change
needs to be reverted for some unimaginable reason, the code base will
still be improved.
If the worst does not happen there are a more cleanups that can be
made. Signals that generate coredumps can easily become eligible for
short circuit delivery in complete_signal. The entire rendezvous for
generating a coredump can move into get_signal. The function
force_sig_info_to_task be written in a way that does not modify the
signal handling state of the target task (because coredumps are
eligible for short circuit delivery). Many of these future cleanups
can be done another way but nothing so cleanly as if coredumps become
per signal_struct"
* 'per_signal_struct_coredumps-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
coredump: Limit coredumps to a single thread group
coredump: Don't perform any cleanups before dumping core
exit: Factor coredump_exit_mm out of exit_mm
exec: Check for a pending fatal signal instead of core_state
ptrace: Remove the unnecessary arguments from arch_ptrace_stop

When building m68k:allmodconfig, recent versions of gcc generate the
following error if the length of UTS_RELEASE is less than 8 bytes.
In function 'memcpy_and_pad',
inlined from 'nvmet_execute_disc_identify' at
drivers/nvme/target/discovery.c:268:2: arch/m68k/include/asm/string.h:72:25: error:
'__builtin_memcpy' reading 8 bytes from a region of size 7
Discussions around the problem suggest that this only happens if an
architecture does not provide strlen(), if -ffreestanding is provided as
compiler option, and if CONFIG_FORTIFY_SOURCE=n. All of this is the case
for m68k. The exact reasons are unknown, but seem to be related to the
ability of the compiler to evaluate the return value of strlen() and
the resulting execution flow in memcpy_and_pad(). It would be possible
to work around the problem by using sizeof(UTS_RELEASE) instead of
strlen(UTS_RELEASE), but that would only postpone the problem until the
function is called in a similar way. Uninline memcpy_and_pad() instead
to solve the problem for good.
