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])
c0a001f8 ret_from_fork+0x14 ([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.

Merge tag 'trace-v5.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull more tracing updates from Steven Rostedt:
- osnoise and timerlat updates that will work with the RTLA tool
(Real-Time Linux Analysis).
Specifically it disconnects the work load (threads that look for
latency) from the tracing instances attached to them, allowing for
more than one instance to retrieve data from the work load.
- Optimization on division in the trace histogram trigger code to use
shift and multiply when possible. Also added documentation.
- Fix prototype to my_direct_func in direct ftrace trampoline sample
code.

together in one synchronization.
- Allow histogram triggers to add variables that can perform calculations
against the event's fields.

from the compiler.
- Extend histogram triggers to key off of variables.
- Have trace recursion use bit magic to determine preempt context over if
branches.
- Have trace recursion disable preemption as all use cases do anyway.

Deprecate AF_XDP support in libbpf ([0]). This has been moved to
libxdp as it is a better fit for that library. The AF_XDP support only
uses the public libbpf functions and can therefore just use libbpf as
a library from libxdp. The libxdp APIs are exactly the same so it
should just be linking with libxdp instead of libbpf for the AF_XDP
functionality. If not, please submit a bug report. Linking with both
libraries is supported but make sure you link in the correct order so
that the new functions in libxdp are used instead of the deprecated
ones in libbpf.
Libxdp can be found at https://github.com/xdp-project/xdp-tools.

Before this fix:
166: (b5) if r2 <= 0x1 goto pc+22
from 166 to 189: R2=invP(id=1,umax_value=1,var_off=(0x0; 0xffffffff))
After this fix:

from 166 to 189: R2=invP(id=1,umax_value=1,var_off=(0x0; 0x1))
While processing BPF_JLE the reg_set_min_max() would set true_reg->umax_value = 1
and call __reg_combine_64_into_32(true_reg).
Without the fix it would not pass the condition:
if (__reg64_bound_u32(reg->umin_value) && __reg64_bound_u32(reg->umax_value))
since umin_value == 0 at this point.
Before commit 10bf4e83167c the umin was incorrectly ingored.
The commit 10bf4e83167c fixed the correctness issue, but pessimized
propagation of 64-bit min max into 32-bit min max and corresponding var_off.

Previous fix aded bpf_clamp_umax() helper use to re-validate boundaries.
While that works correctly, it introduces more branches, which blows up
past 1 million instructions in no-alu32 variant of strobemeta selftests.
Switching len variable from u32 to u64 also fixes the issue and reduces
the number of validated instructions, so use that instead. Fix this
patch and bpf_clamp_umax() removed, both alu32 and no-alu32 selftests
pass.

This patch has two changes:
1) Adds a new function "test_success_cases" to test
successfully creating + adding + looking up a value
in a bloom filter map from the userspace side.
2) Use bpf_create_map instead of bpf_create_map_xattr in
the "test_fail_cases" and test_inner_map to make the
code look cleaner.

Running a BPF_PROG_TYPE_STRUCT_OPS prog for dummy_st_ops::test_N()
through bpf_prog_test_run(). Four test cases are added:
(1) attach dummy_st_ops should fail
(2) function return value of bpf_dummy_ops::test_1() is expected
(3) pointer argument of bpf_dummy_ops::test_1() works as expected
(4) multiple arguments passed to bpf_dummy_ops::test_2() are correct

- Cleanup of extable fixup handling to be more robust, which in turn
allows to make the FPU exception fixups more robust as well.
- Change the return code for signal frame related failures from explicit
error codes to a boolean fail/success as that's all what the calling
code evaluates.
- A large refactoring of the FPU code to prepare for adding AMX support:
- Distangle the public header maze and remove especially the misnomed
kitchen sink internal.h which is despite it's name included all over
the place.
- Add a proper abstraction for the register buffer storage (struct
fpstate) which allows to dynamically size the buffer at runtime by
flipping the pointer to the buffer container from the default
container which is embedded in task_struct::tread::fpu to a
dynamically allocated container with a larger register buffer.
- Convert the code over to the new fpstate mechanism.
- Consolidate the KVM FPU handling by moving the FPU related code into
the FPU core which removes the number of exports and avoids adding
even more export when AMX has to be supported in KVM. This also
removes duplicated code which was of course unnecessary different and
incomplete in the KVM copy.
- Simplify the KVM FPU buffer handling by utilizing the new fpstate
container and just switching the buffer pointer from the user space
buffer to the KVM guest buffer when entering vcpu_run() and flipping
it back when leaving the function. This cuts the memory requirements
of a vCPU for FPU buffers in half and avoids pointless memory copy
operations.
This also solves the so far unresolved problem of adding AMX support
because the current FPU buffer handling of KVM inflicted a circular
dependency between adding AMX support to the core and to KVM. With
the new scheme of switching fpstate AMX support can be added to the
core code without affecting KVM.
- Replace various variables with proper data structures so the extra
information required for adding dynamically enabled FPU features (AMX)
can be added in one place
- Add AMX (Advanved Matrix eXtensions) support (finally):
AMX is a large XSTATE component which is going to be available with
Saphire Rapids XEON CPUs. The feature comes with an extra MSR (MSR_XFD)
which allows to trap the (first) use of an AMX related instruction,
which has two benefits:
1) It allows the kernel to control access to the feature
2) It allows the kernel to dynamically allocate the large register
state buffer instead of burdening every task with the the extra 8K
or larger state storage.
It would have been great to gain this kind of control already with
AVX512.
The support comes with the following infrastructure components:
1) arch_prctl() to
- read the supported features (equivalent to XGETBV(0))
- read the permitted features for a task
- request permission for a dynamically enabled feature
Permission is granted per process, inherited on fork() and cleared
on exec(). The permission policy of the kernel is restricted to
sigaltstack size validation, but the syscall obviously allows
further restrictions via seccomp etc.
2) A stronger sigaltstack size validation for sys_sigaltstack(2) which
takes granted permissions and the potentially resulting larger
signal frame into account. This mechanism can also be used to
enforce factual sigaltstack validation independent of dynamic
features to help with finding potential victims of the 2K
sigaltstack size constant which is broken since AVX512 support was
added.
3) Exception handling for #NM traps to catch first use of a extended
feature via a new cause MSR. If the exception was caused by the use
of such a feature, the handler checks permission for that
feature. If permission has not been granted, the handler sends a
SIGILL like the #UD handler would do if the feature would have been
disabled in XCR0. If permission has been granted, then a new fpstate
which fits the larger buffer requirement is allocated.
In the unlikely case that this allocation fails, the handler sends
SIGSEGV to the task. That's not elegant, but unavoidable as the
other discussed options of preallocation or full per task
permissions come with their own set of horrors for kernel and/or
userspace. So this is the lesser of the evils and SIGSEGV caused by
unexpected memory allocation failures is not a fundamentally new
concept either.
When allocation succeeds, the fpstate properties are filled in to
reflect the extended feature set and the resulting sizes, the
fpu::fpstate pointer is updated accordingly and the trap is disarmed
for this task permanently.
4) Enumeration and size calculations
5) Trap switching via MSR_XFD
The XFD (eXtended Feature Disable) MSR is context switched with the
same life time rules as the FPU register state itself. The mechanism
is keyed off with a static key which is default disabled so !AMX
equipped CPUs have zero overhead. On AMX enabled CPUs the overhead
is limited by comparing the tasks XFD value with a per CPU shadow
variable to avoid redundant MSR writes. In case of switching from a
AMX using task to a non AMX using task or vice versa, the extra MSR
write is obviously inevitable.
All other places which need to be aware of the variable feature sets
and resulting variable sizes are not affected at all because they
retrieve the information (feature set, sizes) unconditonally from
the fpstate properties.
6) Enable the new AMX states
Note, this is relatively new code despite the fact that AMX support is in
the works for more than a year now.
The big refactoring of the FPU code, which allowed to do a proper
integration has been started exactly 3 weeks ago. Refactoring of the
existing FPU code and of the original AMX patches took a week and has
been subject to extensive review and testing. The only fallout which has
not been caught in review and testing right away was restricted to AMX
enabled systems, which is completely irrelevant for anyone outside Intel
and their early access program. There might be dragons lurking as usual,
but so far the fine grained refactoring has held up and eventual yet
undetected fallout is bisectable and should be easily addressable before
the 5.16 release. Famous last words...
Many thanks to Chang Bae and Dave Hansen for working hard on this and
also to the various test teams at Intel who reserved extra capacity to
follow the rapid development of this closely which provides the
confidence level required to offer this rather large update for inclusion
into 5.16-rc1.

Pull locking updates from Thomas Gleixner:
- Move futex code into kernel/futex/ and split up the kitchen sink into
seperate files to make integration of sys_futex_waitv() simpler.
- Add a new sys_futex_waitv() syscall which allows to wait on multiple
futexes.
The main use case is emulating Windows' WaitForMultipleObjects which
allows Wine to improve the performance of Windows Games. Also native
Linux games can benefit from this interface as this is a common wait
pattern for this kind of applications.
- Add context to ww_mutex_trylock() to provide a path for i915 to
rework their eviction code step by step without making lockdep upset
until the final steps of rework are completed. It's also useful for
regulator and TTM to avoid dropping locks in the non contended path.
- Lockdep and might_sleep() cleanups and improvements
- A few improvements for the RT substitutions.
- The usual small improvements and cleanups.

This patch is closely related to commit 6016df8fe874 ("selftests/bpf:
Fix broken riscv build"). When clang includes the system include
directories, but targeting BPF program, __BITS_PER_LONG defaults to
32, unless explicitly set. Work around this problem, by explicitly
setting __BITS_PER_LONG to __riscv_xlen.

Add RISC-V to the HOSTARCH parsing, so that ARCH is "riscv", and not
"riscv32" or "riscv64".
This affects the perf and libbpf builds, so that arch specific
includes are correctly picked up for RISC-V.

After "skmsg: lose offset info in sk_psock_skb_ingress", the test case
with ktls failed. This because ktls parser(tls_read_size) return value
is 285 not 256.
The case like this:
tls_sk1 --> redir_sk --> tls_sk2
tls_sk1 sent out 512 bytes data, after tls related processing redir_sk
recved 570 btyes data, and redirect 512 (skb_use_parser) bytes data to
tls_sk2; but tls_sk2 needs 285 * 2 bytes data, receive timeout occurred.

This reverts commit c1ff12dac4657e0134c972978479b97f652711a2.
This commit makes the build break on ubuntu 20.04 and other older
systems and it as well has identation problems, lets revert it till we
get these problems fixed.
