perf record: Fix synthesis failure warnings
Some calls to synthesis functions set err < 0 but only warn about the
failure and continue. However they do not set err back to zero, relying
on subsequent code to do that.
That changed with the introduction of option --synth. When --synth=no
subsequent functions that set err back to zero are not called.
Fix by setting err = 0 in those cases.
Example:
Before:
$ perf record --no-bpf-event --synth=all -o /tmp/huh uname
Couldn't synthesize bpf events.
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.014 MB /tmp/huh (7 samples) ]
$ perf record --no-bpf-event --synth=no -o /tmp/huh uname
Couldn't synthesize bpf events.
After:
$ perf record --no-bpf-event --synth=no -o /tmp/huh uname
Couldn't synthesize bpf events.

libperf evlist: Fix per-thread mmaps for multi-threaded targets
The offending commit removed mmap_per_thread(), which did not consider
the different set-output rules for per-thread mmaps i.e. in the per-thread
case set-output is used for file descriptors of the same thread not the
same cpu.
This was not immediately noticed because it only happens with
multi-threaded targets and we do not have a test for that yet.
Reinstate mmap_per_thread() expanding it to cover also system-wide per-cpu
events i.e. to continue to allow the mixing of per-thread and per-cpu
mmaps.
Debug messages (with -vv) show the file descriptors that are opened with
sys_perf_event_open. New debug messages are added (needs -vvv) that show
also which file descriptors are mmapped and which are redirected with
set-output.
In the per-cpu case (cpu != -1) file descriptors for the same CPU are
set-output to the first file descriptor for that CPU.
In the per-thread case (cpu == -1) file descriptors for the same thread are
set-output to the first file descriptor for that thread.
Example (process 17489 has 2 threads):
Before (but with new debug prints):
$ perf record --no-bpf-event -vvv --per-thread -p 17489
<SNIP>
sys_perf_event_open: pid 17489 cpu -1 group_fd -1 flags 0x8 = 5
sys_perf_event_open: pid 17490 cpu -1 group_fd -1 flags 0x8 = 6
<SNIP>
libperf: idx 0: mmapping fd 5
libperf: idx 0: set output fd 6 -> 5
failed to mmap with 22 (Invalid argument)
After:
$ perf record --no-bpf-event -vvv --per-thread -p 17489
<SNIP>
sys_perf_event_open: pid 17489 cpu -1 group_fd -1 flags 0x8 = 5
sys_perf_event_open: pid 17490 cpu -1 group_fd -1 flags 0x8 = 6
<SNIP>
libperf: mmap_per_thread: nr cpu values (may include -1) 1 nr threads 2
libperf: idx 0: mmapping fd 5
libperf: idx 1: mmapping fd 6
<SNIP>
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.018 MB perf.data (15 samples) ]
Per-cpu example (process 20341 has 2 threads, same as above):
$ perf record --no-bpf-event -vvv -p 20341
<SNIP>
sys_perf_event_open: pid 20341 cpu 0 group_fd -1 flags 0x8 = 5

tools/perf: Fix out of bound access to cpu mask array
The cpu mask init code in "record__mmap_cpu_mask_init" function access "bits" array part of "struct mmap_cpu_mask". The size of this array is the value from cpu__max_cpu().cpu.

perf affinity: Fix out of bound access to "sched_cpus" mask
The affinity code in "affinity_set" function access array named
"sched_cpus". The size for this array is allocated in affinity_setup
function which is nothing but value from get_cpu_set_size. This is used
to contain the cpumask value for each cpu.
While setting bit for each cpu, it calls "set_bit" function which access
index in sched_cpus array. If we provide a command-line option to -C
which is more than the number of CPU's present in the system, the
set_bit could access an array member which is out-of the array size.
This is because currently, there is no boundary check for the CPU. This
will result in seg fault:
<<>>

Florian Westphal says: ==================== netfilter: bug fixes for net 1. Fix IP address check in irc DCC conntrack helper, this should check the opposite direction rather than the destination address of the packets' direction, from David Leadbeater. 2. bridge netfilter needs to drop dst references, from Harsh Modi. This was fine back in the day the code was originally written, but nowadays various tunnels can pre-set metadata dsts on packets. 3. Remove nf_conntrack_helper sysctl and the modparam toggle, users need to explicitily assign the helpers to use via nftables or iptables. Conntrack helpers, by design, may be used to add dynamic port redirections to internal machines, so its necessary to restrict which hosts/peers are allowed to use them. It was discovered that improper checking in the irc DCC helper makes it possible to trigger the 'please do dynamic port forward' from outside by embedding a 'DCC' in a PING request; if the client echos that back a expectation/port forward gets added. The auto-assign-for-everything mechanism has been in "please don't do this" territory since 2012. From Pablo. 4. Fix a memory leak in the netdev hook error unwind path, also from Pablo. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_conntrack_irc: Fix forged IP logic netfilter: nf_tables: clean up hook list when offload flags check fails netfilter: br_netfilter: Drop dst references before setting. netfilter: remove nf_conntrack_helper sysctl and modparam toggles ==================== Link: https://lore.kernel.org/r/20220901071238.3044-1-fw@strlen.de Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

perf stat: Fix L2 Topdown metrics disappear for raw events
In perf/Documentation/perf-stat.txt, for "--td-level" the default "0" means
the max level that the current hardware support.
So we need initialize the stat_config.topdown_level to TOPDOWN_MAX_LEVEL
when “--td-level=0” or no “--td-level” option. Otherwise, for the
hardware with a max level is 2, the 2nd level metrics disappear for raw
events in this case.
The issue cannot be observed for the perf stat default or "--topdown"
options. This commit fixes the raw events issue and removes the
duplicated code for the perf stat default.

landlock: Fix file reparenting without explicit LANDLOCK_ACCESS_FS_REFER
This change fixes a mis-handling of the LANDLOCK_ACCESS_FS_REFER right when multiple rulesets/domains are stacked. The expected behaviour was that an additional ruleset can only restrict the set of permitted operations, but in this particular case, it was potentially possible to re-gain the LANDLOCK_ACCESS_FS_REFER right. With the introduction of LANDLOCK_ACCESS_FS_REFER, we added the first globally denied-by-default access right. Indeed, this lifted an initial Landlock limitation to rename and link files, which was initially always denied when the source or the destination were different directories. This led to an inconsistent backward compatibility behavior which was only taken into account if no domain layer were using the new LANDLOCK_ACCESS_FS_REFER right. However, when restricting a thread with a new ruleset handling LANDLOCK_ACCESS_FS_REFER, all inherited parent rulesets/layers not explicitly handling LANDLOCK_ACCESS_FS_REFER would behave as if they were handling this access right and with all their rules allowing it. This means that renaming and linking files could became allowed by these parent layers, but all the other required accesses must also be granted: all layers must allow file removal or creation, and renaming and linking operations cannot lead to privilege escalation according to the Landlock policy. See detailed explanation in commit |

perf record: Fix manpage formatting of description of support to hybrid systems
The Intel hybrid description is written in a different style than the rest of the perf record man page. There were some new command line options added after it which resulted in very strange section ordering. Move the hybrid include last. Also the sub sections in the hybrid document don't fit the record manpage well (especially since it talks about all kinds of unrelated commands). I left this for now, but would be better to separate this properly in the different man pages. It would be better to use sub sections for the other sections, but these don't seem to be supported in AsciiDoc? Some of the examples are still misrendered in the manpage with an indented troff command, but I don't know how to fix that. In any case it's now better than before.

perf stat: Clear evsel->reset_group for each stat run
If a weak group is broken then the reset_group flag remains set for
the next run. Having reset_group set means the counter isn't created
and ultimately a segfault.
A simple reproduction of this is:
# perf stat -r2 -e '{cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles}:W

perf python: Fix build when PYTHON_CONFIG is user supplied
The previous change to Python autodetection had a small mistake where the auto value was used to determine the Python binary, rather than the user supplied value. The Python binary is only used for one part of the build process, rather than the final linking, so it was producing correct builds in most scenarios, especially when the auto detected value matched what the user wanted, or the system only had a valid set of Pythons. Change it so that the Python binary path is derived from either the PYTHON_CONFIG value or PYTHON value, depending on what is specified by the user. This was the original intention. This error was spotted in a build failure an odd cross compilation environment after commit |

asm goto: eradicate CC_HAS_ASM_GOTO
GCC has supported asm goto since 4.5, and Clang has since version 9.0.0. The minimum supported versions of these tools for the build according to Documentation/process/changes.rst are 5.1 and 11.0.0 respectively. Remove the feature detection script, Kconfig option, and clean up some fallback code that is no longer supported. The removed script was also testing for a GCC specific bug that was fixed in the 4.7 release. Also remove workarounds for bpftrace using clang older than 9.0.0, since other BPF backend fixes are required at this point.

selftests/vm: fix inability to build any vm tests
When we stopped using KSFT_KHDR_INSTALL, a side effect is we also changed the value of `top_srcdir`. This can be seen by looking at the code removed by commit |

perf tools: Support reading PERF_FORMAT_LOST
The recent kernel added lost count can be read from either read(2) or ring buffer data with PERF_SAMPLE_READ. As it's a variable length data we need to access it according to the format info. But for perf tools use cases, PERF_FORMAT_ID is always set. So we can only check PERF_FORMAT_LOST bit to determine the data format. Add sample_read_value_size() and next_sample_read_value() helpers to make it a bit easier to access. Use them in all places where it reads the struct sample_read_value.
