Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Fix bogus test reports in rpath.sh selftest by adding permanent
neighbor entries, from Phil Sutter.
2) Lockdep reports possible ABBA deadlock in xt_IDLETIMER, fix it by
removing sysfs out of the mutex section, also from Phil Sutter.
3) It is illegal to release basechain via RCU callback, for several
reasons. Keep it simple and safe by calling synchronize_rcu() instead.
This is a partially reverting a botched recent attempt of me to fix
this basechain release path on netdevice removal.

Historically, DSA drivers have seen problems with the model in which
bridge VLANs work, particularly with them being offloaded to switchdev
asynchronously relative to when they become active (vlan_filtering=1).
This switchdev API peculiarity was papered over by commit 2ea7a679ca
("net: dsa: Don't add vlans when vlan filtering is disabled"), which
introduced other problems, fixed by commit 54a0ed0df4 ("net: dsa:
provide an option for drivers to always receive bridge VLANs") through
an opt-in ds->configure_vlan_while_not_filtering bool (which later
became an opt-out).
The point is that some DSA drivers still skip VLAN configuration while
VLAN-unaware, and there is a desire to get rid of that behavior.
It's hard to deduce from the wording "at least one corner case" what
Andrew saw, but my best guess is that there is a discrepancy of meaning
between bridge pvid and hardware port pvid which caused breakage.
On one side, the Linux bridge with vlan_filtering=0 is completely
VLAN-unaware, and will accept and process a packet the same way
irrespective of the VLAN groups on the ports or the bridge itself
(there may not even be a pvid, and this makes no difference).
On the other hand, DSA switches still do VLAN processing internally,
even with vlan_filtering disabled, but they are expected to classify all
packets to the port pvid. That pvid shouldn't be confused with the
bridge pvid, and there lies the problem.
When a switch port is under a VLAN-unaware bridge, the hardware pvid
must be explicitly managed by the driver to classify all received
packets to it, regardless of bridge VLAN groups. When under a VLAN-aware
bridge, the hardware pvid must be synchronized to the bridge port pvid.
To do this correctly, the pattern is unfortunately a bit complicated,
and involves hooking the pvid change logic into quite a few places
(the ones that change the input variables which determine the value to
use as hardware pvid for a port). See mv88e6xxx_port_commit_pvid(),
sja1105_commit_pvid(), ocelot_port_set_pvid() etc.
The point is that not all drivers used to do that, especially in older
kernels. If a driver is to blindly program a bridge pvid VLAN received
from switchdev while it's VLAN-unaware, this might in turn change the
hardware pvid used by a VLAN-unaware bridge port, which might result in
packet loss depending which other ports have that pvid too (in that same
note, it might also go unnoticed).
To capture that condition, it is sufficient to take a VLAN-unaware
bridge and change the [VLAN-aware] bridge pvid on a single port, to a
VID that isn't present on any other port. This shouldn't have absolutely
any effect on packet classification or forwarding. However, broken
drivers will take the bait, and change their PVID to 3, causing packet
loss.

On some systems, neighbor discoveries from ns1 for fec0:42::1 (i.e., the
martian trap address) would happen at the wrong time and cause
false-negative test result.
Problem analysis also discovered that IPv6 martian ping test was broken
in that sent neighbor discoveries, not echo requests were inadvertently
trapped
Avoid the race condition by introducing the neighbors to each other
upfront. Also pin down the firewall rules to matching on echo requests
only.

- fix the offset for kprobe syntax error test case when checking the

* tag 'linux_kselftest-fixes-6.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest:
selftests/ftrace: adjust offset for kprobe syntax error test
In 'NOFENTRY_ARGS' test case for syntax check, any offset X of
`vfs_read+X` except function entry offset (0) fits the criterion,
even if that offset is not at instruction boundary, as the parser
comes before probing. But with "ENDBR64" instruction on x86, offset
4 is treated as function entry. So, X can't be 4 as well. Thus, 8
was used as offset for the test case. On 64-bit powerpc though, any
offset <= 16 can be considered function entry depending on build
configuration (see arch_kprobe_on_func_entry() for implementation
details). So, use `vfs_read+20` to accommodate that scenario too.

Isolated CPUs are not allowed to be used in a non-isolated partition.
The only exception is the top cpuset which is allowed to contain boot
time isolated CPUs.
Commit ccac8e8de9 ("cgroup/cpuset: Fix remote root partition creation
problem") introduces a simplified scheme of including only partition
roots in sched domain generation. However, it does not properly account
for this exception case. This can result in leakage of isolated CPUs
into a sched domain.
Fix it by making sure that isolated CPUs are excluded from the top
cpuset before generating sched domains.
Also update the way the boot time isolated CPUs are handled in
test_cpuset_prs.sh to make sure that those isolated CPUs are really
isolated instead of just skipping them in the tests.

Tail-called programs could execute any of the helpers that invalidate
packet pointers. Hence, conservatively assume that each tail call
invalidates packet pointers.
Making the change in bpf_helper_changes_pkt_data() automatically makes
use of check_cfg() logic that computes 'changes_pkt_data' effect for
global sub-programs, such that the following program could be
rejected:
int tail_call(struct __sk_buff *sk)
{
bpf_tail_call_static(sk, &jmp_table, 0);
return 0;
}
SEC("tc")
int not_safe(struct __sk_buff *sk)
{
int *p = (void *)(long)sk->data;
... make p valid ...
tail_call(sk);
*p = 42; /* this is unsafe */
...
}
The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function that
can invalidate packet pointers. Otherwise, it can't be freplaced with
tailcall_freplace.c:entry_freplace() that does a tail call.

With CONFIG_KPROBES_ON_FTRACE enabled on powerpc, ftrace_location_range
returns ftrace location for bpf_fentry_test1 at offset of 4 bytes from
function entry. This is because branch to _mcount function is at offset
of 4 bytes in function profile sequence.
To fix this, add entry_offset of 4 bytes while verifying the address for
kprobe entry address of bpf_fentry_test1 in verify_perf_link_info in
selftest, when CONFIG_KPROBES_ON_FTRACE is enabled.
Disassemble of bpf_fentry_test1:
c000000000e4b080 <bpf_fentry_test1>:
c000000000e4b080: a6 02 08 7c mflr r0

c000000000e4b090: 20 00 80 4e blr
When CONFIG_PPC_FTRACE_OUT_OF_LINE [1] is enabled, these function profile
sequence is moved out of line with an unconditional branch at offset 0.
So, the test works without altering the offset for
'CONFIG_KPROBES_ON_FTRACE && CONFIG_PPC_FTRACE_OUT_OF_LINE' case.

The selftests build four kernel modules which use copy-pasted Makefile
targets. This is a bit messy, and doesn't scale so well when we add more
modules, so let's consolidate these rules into a single rule generated
for each module name, and move the module sources into a single
directory.
To avoid parallel builds of the different modules stepping on each
other's toes during the 'modpost' phase of the Kbuild 'make modules',
the module files should really be a grouped target. However, make only
added explicit support for grouped targets in version 4.3, which is
newer than the minimum version supported by the kernel. However, make
implicitly treats pattern matching rules with multiple targets as a
grouped target, so we can work around this by turning the rule into a
pattern matching target. We do this by replacing '.ko' with '%ko' in the
targets with subst().

Add more test cases for LPM trie in test_maps:
1) test_lpm_trie_update_flags
It constructs various use cases for BPF_EXIST and BPF_NOEXIST and check
whether the return value of update operation is expected.
2) test_lpm_trie_update_full_maps
It tests the update operations on a full LPM trie map. Adding new node
will fail and overwriting the value of existed node will succeed.
3) test_lpm_trie_iterate_strs and test_lpm_trie_iterate_ints
There two test cases test whether the iteration through get_next_key is
sorted and expected. These two test cases delete the minimal key after
each iteration and check whether next iteration returns the second
minimal key. The only difference between these two test cases is the
former one saves strings in the LPM trie and the latter saves integers.
Without the fix of get_next_key, these two cases will fail as shown
below:
test_lpm_trie_iterate_strs(1091):FAIL:iterate #2 got abc exp abS
test_lpm_trie_iterate_ints(1142):FAIL:iterate #1 got 0x2 exp 0x1

Replace setsockopt() calls with calls to functions that follow
setsockopt() with getsockopt() and check that the returned value and its
size are the same as have been set. (Except in vsock_perf.)

Change parameters of SO_VM_SOCKETS_* to unsigned long long as documented
in the vm_sockets.h, because the corresponding kernel code requires them
to be at least 64-bit, no matter what architecture. Otherwise they are
too small on 32-bit machines.

This happens on 64-bit big-endian machines.
SO_RCVLOWAT requires an int parameter. However, instead of int, the test
uses unsigned long in one place and size_t in another. Both are 8 bytes
long on 64-bit machines. The kernel, having received the 8 bytes, doesn't
test for the exact size of the parameter, it only cares that it's >=
sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on
a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT
returns with success and the socket stays with the default SO_RCVLOWAT = 1,
which results in vsock_test failures, while vsock_perf doesn't even notice
that it's failed to change it.

Ensure that when CAP_PERFMON is dropped, and the verifier sees
allow_ptr_leaks as false, we are not permitted to read from a
STACK_INVALID slot. Without the fix, the test will report unexpected
success in loading.
