perf stat: Fix forked applications enablement of counters
I have run into the following issue:
# perf stat -a -e new_pmu/INSTRUCTION_7/ -- mytest -c1 7
Performance counter stats for 'system wide':
0 new_pmu/INSTRUCTION_7/
0.000366428 seconds time elapsed
#
The new PMU for s390 counts the execution of certain CPU instructions.
The root cause is the extremely small run time of the mytest program. It
just executes some assembly instructions and then exits.
In above invocation the instruction is executed exactly one time (-c1
option). The PMU is expected to report this one time execution by a
counter value of one, but fails to do so in some cases, not all.
Debugging reveals the invocation of the child process is done
*before* the counter events are installed and enabled.
Tracing reveals that sometimes the child process starts and exits before
the event is installed on all CPUs. The more CPUs the machine has, the
more often this miscount happens.
Fix this by reversing the start of the work load after the events have
been installed on the specified CPUs. Now the comment also matches the
code.
Output after:
# perf stat -a -e new_pmu/INSTRUCTION_7/ -- mytest -c1 7
Performance counter stats for 'system wide':
1 new_pmu/INSTRUCTION_7/
0.000366428 seconds time elapsed
#
Now the correct result is reported rock solid all the time regardless
how many CPUs are online.
Reviewers notes:
Jiri:
Right, without -a the event has enable_on_exec so the race does not
matter, but it's a problem for system wide with fork.
Namhyung:
Agreed. Also we may move the enable_counters() and the clock code out of
the if block to be shared with the else block.

perf evsel: Make evsel__env() always return a valid env
It's possible to have an evsel and evsel->evlist populated without
an evsel->evlist->env, when, e.g., cmd_record is in its error path.
Future patches will add support for evsel__open_strerror to be able
to customize error messaging based on perf_env__{arch,cpuid}, so
let's have evsel__env return &perf_env instead of NULL in that case.

perf script: Add 'brstackinsnlen' for branch stacks
When analyzing with 'perf script', it's useful to understand the
captured instruction and the next sequential instruction.
To calculate the address of the next sequential instruction, the length
of the captured instruction is required.
For example, you can’t know the next sequential instruction after an
unconditional branch unless you calculate that based on its length.
For branch stacks, 'perf script' only prints the instruction bytes with
'brstackinsn', but lacks the instruction length.
Add 'brstackinsnlen' to print the instruction length.
$ perf script -F ip,brstackinsn,brstackinsnlen --xed

perf parse-events: Move slots only with topdown
If slots isn't with a topdown event then moving it is unnecessary. For
example {instructions, slots} is re-ordered:
$ perf stat -e '{instructions,slots}' -a sleep 1
Performance counter stats for 'system wide':
936,600,825 slots
144,440,968 instructions
1.006061423 seconds time elapsed
Which can break tools expecting the command line order to match the
printed order. It is necessary to move the slots event first when it
appears with topdown events. Add extra checking so that the slots event
is only moved in the case of there being a topdown event like:
$ perf stat -e '{instructions,slots,topdown-fe-bound}' -a sleep 1
Performance counter stats for 'system wide':
2427568570 slots
300927614 instructions
551021649 topdown-fe-bound
1.001771803 seconds time elapsed

perf tools: Fix version kernel tag
Generating the version kernel tag relies on "git describe" command to
get the latest Linus kernel tag.
However, when working from clones of Linus' git we may not have the latest
tag. For example, when working on Arnaldo's acme.git, we can have this:
$ git branch
perf/core
$ head -n 5 ../../Makefile | tail -n 4
VERSION = 5
PATCHLEVEL = 17
SUBLEVEL = 0
EXTRAVERSION = -rc3
$ git describe --abbrev=0 --match "v[0-9].[0-9]*"
v4.13-rc5
Indeed using tags is a problem as it relies on tags being pulled from
Linus' git (and pushed to the clone).

perf tools: Fix dependency for version file creation
The version generated by perf may not be correct by just changing the head commit, like this: $ git log --pretty=format:"%H" -n 1 b5d9d4708a24ac1889a30e9aedf8af8d73102139 $ 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).

Reenable ENQCMD/PASID support:
- Simplify the PASID handling to allocate the PASID once, associate it to
the mm of a process and free it on mm_exit(). The previous attempt of
refcounted PASIDs and dynamic alloc()/free() turned out to be error
prone and too complex. The PASID space is 20bits, so the case of
resource exhaustion is a pure academic concern.
- Populate the PASID MSR on demand via #GP to avoid racy updates via IPIs.
- Reenable ENQCMD and let objtool check for the forbidden usage of ENQCMD
in the kernel.
- Update the documentation for Shared Virtual Addressing accordingly.

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"

https://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git/tree/tools/perf/pmu-events/arch/x86/icelakex/icx-metrics.json?h=perf/core&id=65eab2bc7dab326ee892ec5a4c749470b368b51a#n48
That causes the slots not to be first.

perf symbols: Fix symbol size calculation condition
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.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net coming late
in the 5.17-rc process:
1) Revert port remap to mitigate shadowing service ports, this is causing
problems in existing setups and this mitigation can be achieved with
explicit ruleset, eg.
... tcp sport < 16386 tcp dport >= 32768 masquerade random
This patches provided a built-in policy similar to the one described above.
2) Disable register tracking infrastructure in nf_tables. Florian reported
two issues:
- Existing expressions with no implemented .reduce interface
that causes data-store on register should cancel the tracking.
- Register clobbering might be possible storing data on registers that
are larger than 32-bits.
This might lead to generating incorrect ruleset bytecode. These two
issues are scheduled to be addressed in the next release cycle.

perf parse: Fix event parser error for hybrid systems
This bug happened on hybrid systems when both cpu_core and cpu_atom have the same event name such as "UOPS_RETIRED.MS" while their event terms are different, then during perf stat, the event for cpu_atom will parse fail and then no output for cpu_atom. UOPS_RETIRED.MS -> cpu_core/period=0x1e8483,umask=0x4,event=0xc2,frontend=0x8/ UOPS_RETIRED.MS -> cpu_atom/period=0x1e8483,umask=0x1,event=0xc2/ It is because event terms in the "head" of parse_events_multi_pmu_add will be changed to event terms for cpu_core after parsing UOPS_RETIRED.MS for cpu_core, then when parsing the same event for cpu_atom, it still uses the event terms for cpu_core, but event terms for cpu_atom are different with cpu_core, the event parses for cpu_atom will fail. This patch fixes it, the event terms should be parsed from the original event. This patch can work for the hybrid systems that have the same event in more than 2 PMUs. It also can work in non-hybrid systems. Before: # perf stat -v -e UOPS_RETIRED.MS -a sleep 1 Using CPUID GenuineIntel-6-97-1 UOPS_RETIRED.MS -> cpu_core/period=0x1e8483,umask=0x4,event=0xc2,frontend=0x8/ Control descriptor is not initialized UOPS_RETIRED.MS: |

perf tools: Set build-id using build-id header on new mmap records
MMAP records that occur after the build-id header is parsed do not have their build-id set even if the filename matches an entry from the header. Set the build-id on these dsos as long as the MMAP record doesn't have its own build-id set. This fixes an issue with off target analysis where the local version of a dso is loaded rather than one from ~/.debug via a build-id.
