Pull seccomp fixes from Kees Cook:
"Fixes for seccomp_notify_ioctl uapi sanity from Sargun Dhillon.
The bulk of this is fixing the surrounding samples and selftests so
that seccomp can correctly validate the seccomp_notify_ioctl buffer as
being initially zeroed.
Summary:
- Fix samples and selftests to zero passed-in buffer
- Enforce zeroed buffer checking
- Verify buffer sanity check in selftest"
* tag 'seccomp-v5.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
selftests/seccomp: Catch garbage on SECCOMP_IOCTL_NOTIF_RECV
seccomp: Check that seccomp_notif is zeroed out by the user
selftests/seccomp: Zero out seccomp_notif
samples/seccomp: Zero out members based on seccomp_notif_sizes
|
|
This adds logic to the user_notification_basic test to set a member
of struct seccomp_notif to an invalid value to ensure that the kernel
returns EINVAL if any of the struct seccomp_notif members are set to
invalid values.

The seccomp_notif structure should be zeroed out prior to calling the
SECCOMP_IOCTL_NOTIF_RECV ioctl. Previously, the kernel did not check
whether these structures were zeroed out or not, so these worked.
This patch zeroes out the seccomp_notif data structure prior to calling
the ioctl.

The rseq.h UAPI now documents that the rseq_cs field must be cleared
before reclaiming memory that contains the targeted struct rseq_cs, but
also that the rseq_cs field must be cleared before reclaiming memory of
the code pointed to by the rseq_cs start_ip and post_commit_offset
fields.
While we can expect that use of dlclose(3) will typically unmap
both struct rseq_cs and its associated code at once, nothing would
theoretically prevent a JIT from reclaiming the code without
reclaiming the struct rseq_cs, which would erroneously allow the
kernel to consider new code which is not a rseq critical section
as a rseq critical section following a code reclaim.

When I use prefix=/usr and try to install libtraceevent in my laptop it
tries to install in /usr/lib64. I am not having any folder as /usr/lib64
and also the debian policy doesnot allow installing in /usr/lib64. It
should be in /usr/lib/x86_64-linux-gnu/.
Quote: No package for a 64 bit architecture may install files in
/usr/lib64/ or in a subdirectory of it.
ref: https://www.debian.org/doc/debian-policy/ch-opersys.html
Make it more flexible by allowing to mention libdir_relative while
installing so that distros can mention the path according to their
policy or use the default one.

This test only works when [1] is applied, which was rejected.
Basically, the errors are reported and cleared. In this particular case of
tls sockets, following reads will block.
The test case was originally submitted with the rejected patch, but, then,
was included as part of a different patchset, possibly by mistake.

Before this patch, perf expected that there might be NPROC*4 unique
cache entries at max, however, it also expected that some of them would
be shared and/or of the same size, thus the final number of entries
would be reduced to be lower than NPROC*4. In case the number of entries
hadn't been reduced (was NPROC*4), the warning was printed.
However, some systems might have unusual cache topology, such as the
following two-processor KVM guest:
cpu level shared_cpu_list size
0 1 0 32K
0 1 0 64K
0 2 0 512K
0 3 0 8192K
1 1 1 32K
1 1 1 64K
1 2 1 512K
1 3 1 8192K
This KVM guest has 8 (NPROC*4) unique cache entries, which used to make
perf printing the message, although there actually aren't "way too many
cpu caches".
v2: Removing unused argument.
v3: Unifying the way we obtain number of cpus.
v4: Removed '& UINT_MAX' construct which is redundant.

Commit f01642e4912b ("perf metricgroup: Support multiple events for
metricgroup") introduced support for multiple events in a metric group.
But with the current upstream, metric events names are not printed
properly
In power9 platform:
command:# ./perf stat --metric-only -M translation -C 0 -I 1000 sleep 2
1.000208486
2.000368863
2.001400558
Similarly in skylake platform:
command:./perf stat --metric-only -M Power -I 1000
1.000579994
2.002189493
With current upstream version, issue is with event name comparison logic
in find_evsel_group(). Current logic is to compare events belonging to a
metric group to the events in perf_evlist. Since the break statement is
missing in the loop used for comparison between metric group and
perf_evlist events, the loop continues to execute even after getting a
pattern match, and end up in discarding the matches.
Incase of single metric event belongs to metric group, its working fine,
because in case of single event once it compare all events it reaches to
end of perf_evlist.
Example for single metric event in power9 platform:
command:# ./perf stat --metric-only -M branches_per_inst -I 1000 sleep 1
1.000094653 0.2
1.001337059 0.0
This patch fixes the issue by making sure once we found all events
belongs to that metric event matched in find_evsel_group(), we
successfully break from that loop by adding corresponding condition.
With this patch:
In power9 platform:
command:# ./perf stat --metric-only -M translation -C 0 -I 1000 sleep 2

'perf top' stopped working on hw architectures that do not provide a
get_cpuid() implementation and thus fallback to the weak get_cpuid()
default function.
This is done because at annotation time we may need it in the arch
specific annotation init routine, but that is only being used by arches
that do provide a get_cpuid() implementation:
$ find tools/ -name "*.[ch]" | xargs grep 'evlist->env'
tools/perf/builtin-top.c: top.evlist->env = &perf_env;
tools/perf/util/evsel.c: return evsel->evlist->env;
tools/perf/util/s390-cpumsf.c: sf->machine_type = s390_cpumsf_get_type(session->evlist->env->cpuid);
tools/perf/util/header.c: session->evlist->env = &header->env;
tools/perf/util/sample-raw.c: const char *arch_pf = perf_env__arch(evlist->env);
$
$ find tools/perf/arch -name "*.[ch]" | xargs grep -w get_cpuid
tools/perf/arch/x86/util/auxtrace.c: ret = get_cpuid(buffer, sizeof(buffer));
tools/perf/arch/x86/util/header.c:get_cpuid(char *buffer, size_t sz)
tools/perf/arch/powerpc/util/header.c:get_cpuid(char *buffer, size_t sz)
tools/perf/arch/s390/util/header.c: * Implementation of get_cpuid().

tools/perf/arch/s390/util/header.c: if (buf && get_cpuid(buf, 128))
$
For 'report' or 'script', i.e. tools working on perf.data files, that is
setup while reading the header, its just top that needs to explicitely
read it at tool start.

Some of the functions calling get_cpuid() propagate back the error it
returns, and all are using errno (positive) values, make the weak
default get_cpuid() function return ENOSYS to be consistent and to allow
checking if this is an arch not providing this function or if a provided
one is having trouble getting the cpuid, to decide if the warning should
be provided to the user or just a debug message should be emitted.

When the kptr_restrict sysctl is set, the kernel can fail to return
jited_ksyms or jited_prog_insns, but still have positive values in
nr_jited_ksyms and jited_prog_len. This causes bpftool to crash when

the actual pointers to the instructions and ksyms.
