====================
netfilter patches for net
First patch resolves a regression with vlan header matching, this was
broken since 6.5 release. From myself.
Second patch fixes an ancient problem with sctp connection tracking in
case INIT_ACK packets are delayed. This comes with a selftest, both
patches from Xin Long.
Patch 4 extends the existing nftables audit selftest, from
Phil Sutter.
Patch 5, also from Phil, avoids a situation where nftables
would emit an audit record twice. This was broken since 5.13 days.
Patch 6, from myself, avoids spurious insertion failure if we encounter an
overlapping but expired range during element insertion with the
'nft_set_rbtree' backend. This problem exists since 6.2.

When adding/updating an object, the transaction handler emits suitable
audit log entries already, the one in nft_obj_notify() is redundant. To
fix that (and retain the audit logging from objects' 'update' callback),
Introduce an "audit log free" variant for internal use.

This patch adds a test case to reproduce the SCTP DATA chunk retransmission
timeout issue caused by the improper SCTP collision processing in netfilter
nf_conntrack_proto_sctp.
In this test, client sends a INIT chunk, but the INIT_ACK replied from
server is delayed until the server sends a INIT chunk to start a new
connection from its side. After the connection is complete from server
side, the delayed INIT_ACK arrives in nf_conntrack_proto_sctp.
The delayed INIT_ACK should be dropped in nf_conntrack_proto_sctp instead
of updating the vtag with the out-of-date init_tag, otherwise, the vtag
in DATA chunks later sent by client don't match the vtag in the conntrack
entry and the DATA chunks get dropped.

- Fix filtering of AIA registers in get-reg-list test
In order to use run_kselftest.sh the list of tests must be emitted to
populate kselftest-list.txt.
The powerpc Makefile is written to use EMIT_TESTS. But support for
EMIT_TESTS was dropped in commit d4e59a536f ("selftests: Use runner.sh
for emit targets"). Although prior to that commit a548de0fe8
("selftests: lib.mk: add test execute bit check to EMIT_TESTS") had
already broken run_kselftest.sh for powerpc due to the executable check
using the wrong path.
It can be fixed by replacing the EMIT_TESTS definitions with actual
emit_tests rules in the powerpc Makefiles. This makes run_kselftest.sh
able to run powerpc tests:
$ cd linux
$ export ARCH=powerpc
$ export CROSS_COMPILE=powerpc64le-linux-gnu-
$ make headers
$ make -j -C tools/testing/selftests install
$ grep -c "^powerpc" tools/testing/selftests/kselftest_install/kselftest-list.txt

Currently the AIA ONE_REG registers are reported by get-reg-list
as new registers for various vcpu_reg_list configs whenever Ssaia
is available on the host because Ssaia extension can only be
disabled by Smstateen extension which is not always available.
To tackle this, we should filter-out AIA ONE_REG registers only
when Ssaia can't be disabled for a VCPU.

Same set of ISA_EXT registers are not present on all host because
ISA_EXT registers are visible to the KVM user space based on the
ISA extensions available on the host. Also, disabling an ISA
extension using corresponding ISA_EXT register does not affect
the visibility of the ISA_EXT register itself.
Based on the above, we should filter-out all ISA_EXT registers.

When dynamically linking, Address Sanitizer requires its library to be the
first one to be loaded; this is apparently to ensure that every call to
malloc is intercepted. If using LD_PRELOAD, those listed libraries will
be loaded before the libraries listed in the program's ELF and will
therefore violate this requirement, leading to the below failure and
output from ASan.
commit 58e2847ad2 ("selftests: line buffer test program's stdout")
modified the kselftest runner to force line buffering by forcing the test
programs to run through `stdbuf`. It turns out that stdbuf implements
line buffering by injecting a library via LD_PRELOAD. Therefore selftests
that use ASan started failing.
Fix this by statically linking libasan in the affected test programs,
using the `-static-libasan` option. Note this is already the default for
Clang, but not got GCC.
Test output sample for failing case:
TAP version 13
1..3
# timeout set to 300
# selftests: openat2: openat2_test
# ==4052==ASan runtime does not come first in initial library list;
you should either link runtime to your application or manually preload
it with LD_PRELOAD.
not ok 1 selftests: openat2: openat2_test # exit=1
# timeout set to 300
# selftests: openat2: resolve_test
# ==4070==ASan runtime does not come first in initial library list;

This kselftest fixes update for Linux 6.6-rc2 consists of important
fixes to user_events test and ftrace test.
user_events test has been enabled for default run in Linux 6.6-rc1. The
following fixes are for bugs found since then:
- adds checks for dependencies and skips the test. user_events test
requires root access, and tracefs and user_events enabled. It leaves
tracefs mounted and a fix is in progress for that missing piece.
- creates user_events test-specific Kconfig fragments.
ftrace test fixes:
- unmounts tracefs for recovering environment. Fix identified during the
above mentioned user_events dependencies fix.
- adds softlink to latest log directory improving usage.

netfilter pull request 23-09-13
====================
The following patchset contains Netfilter fixes for net:
1) Do not permit to remove rules from chain binding, otherwise
double rule release is possible, triggering UaF. This rule
deletion support does not make sense and userspace does not use
this. Problem exists since the introduction of chain binding support.
2) rbtree GC worker only collects the elements that have expired.
This operation is not destructive, therefore, turn write into
read spinlock to avoid datapath contention due to GC worker run.
This was not fixed in the recent GC fix batch in the 6.5 cycle.
3) pipapo set backend performs sync GC, therefore, catchall elements
must use sync GC queue variant. This bug was introduced in the
6.5 cycle with the recent GC fixes.
4) Stop GC run if memory allocation fails in pipapo set backend,
otherwise access to NULL pointer to GC transaction object might
occur. This bug was introduced in the 6.5 cycle with the recent
GC fixes.
5) rhash GC run uses an iterator that might hit EAGAIN to rewind,
triggering double-collection of the same element. This bug was
introduced in the 6.5 cycle with the recent GC fixes.
6) Do not permit to remove elements in anonymous sets, this type of
sets are populated once and then bound to rules. This fix is
similar to the chain binding patch coming first in this batch.
API permits since the very beginning but it has no use case from
userspace.

- Add missing LOCKDOWN checks for eventfs callers
When LOCKDOWN is active for tracing, it causes inconsistent state
when some functions succeed and others fail.
- Use dput() to free the top level eventfs descriptor
There was a race between accesses and freeing it.
- Fix a long standing bug that eventfs exposed due to changing timings
by dynamically creating files. That is, If a event file is opened
for an instance, there's nothing preventing the instance from being
removed which will make accessing the files cause use-after-free bugs.
- Fix a ring buffer race that happens when iterating over the ring
buffer while writers are active. Check to make sure not to read
the event meta data if it's beyond the end of the ring buffer sub buffer.
- Fix the print trigger that disappeared because the test to create it
was looking for the event dir field being filled, but now it has the
"ef" field filled for the eventfs structure.
- Remove the unused "dir" field from the event structure.
- Fix the order of the trace_dynamic_info as it had it backwards for the
offset and len fields for which one was for which endianess.
- Fix NULL pointer dereference with eventfs_remove_rec()
If an allocation fails in one of the eventfs_add_*() functions,
the caller of it in event_subsystem_dir() or event_create_dir()
assigns the result to the structure. But it's assigning the ERR_PTR
and not NULL. This was passed to eventfs_remove_rec() which expects
either a good pointer or a NULL, not ERR_PTR. The fix is to not
assign the ERR_PTR to the structure, but to keep it NULL on error.
- Fix list_for_each_rcu() to use list_for_each_srcu() in
dcache_dir_open_wrapper(). One iteration of the code used RCU
but because it had to call sleepable code, it had to be changed
to use SRCU, but one of the iterations was missed.
- Fix synthetic event print function to use "as_u64" instead of
passing in a pointer to the union. To fix big/little endian issues,
the u64 that represented several types was turned into a union to
define the types properly.

Commit 1d56ade032 changed the function get_unpriv_disabled() to
return its results as a bool instead of updating a global variable, but
test_verifier was not updated to keep in line with these changes. Thus
unpriv_disabled is always false in test_verifier and unprivileged tests
are not properly skipped on systems with unprivileged bpf disabled.

Fix to unmount the tracefs if the ftracetest mounted it for recovering
system environment. If the tracefs is already mounted, this does nothing.

Create the config file in user_events directory of testcase which
need more kernel configuration than the default defconfig. User
could use these configs with merge_config.sh script:
The Kconfig CONFIG_USER_EVENTS=y is needed for the test to read
data from the following files,
- "/sys/kernel/tracing/user_events_data"
- "/sys/kernel/tracing/user_events_status"
- "/sys/kernel/tracing/events/user_events/*"
Enable config for specific testcase:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
tools/testing/selftests/user_events/config
Enable configs for all testcases:
(export ARCH=xxx #for cross compiling)
./scripts/kconfig/merge_config.sh .config \
