Christian Brauner reported that even after MSG_OOB data is consumed,
calling close() on the receiver socket causes the peer's recv() to
return -ECONNRESET:
1. send() and recv() an OOB data.
>>> from socket import *
>>> s1, s2 = socketpair(AF_UNIX, SOCK_STREAM)
>>> s1.send(b'x', MSG_OOB)
1
>>> s2.recv(1, MSG_OOB)
b'x'
2. close() for s2 sets ECONNRESET to s1->sk_err even though
s2 consumed the OOB data
>>> s2.close()
>>> s1.recv(10, MSG_DONTWAIT)
...
ConnectionResetError: [Errno 104] Connection reset by peer
Even after being consumed, the skb holding the OOB 1-byte data stays in
the recv queue to mark the OOB boundary and break recv() at that point.
This must be considered while close()ing a socket.
Let's skip the leading consumed OOB skb while checking the -ECONNRESET
condition in unix_release_sock().

Let's add a test case where consecutive concumed OOB skbs stay
at the head of the queue.
Without the previous patch, ioctl(SIOCATMARK) assertion fails.
Before:
# RUN msg_oob.no_peek.ex_oob_ex_oob_oob ...
# msg_oob.c:305:ex_oob_ex_oob_oob:Expected answ[0] (0) == oob_head (1)
# ex_oob_ex_oob_oob: Test terminated by assertion
# FAIL msg_oob.no_peek.ex_oob_ex_oob_oob
not ok 12 msg_oob.no_peek.ex_oob_ex_oob_oob
After:
# RUN msg_oob.no_peek.ex_oob_ex_oob_oob ...
# OK msg_oob.no_peek.ex_oob_ex_oob_oob
ok 12 msg_oob.no_peek.ex_oob_ex_oob_oob

Jann Horn reported a use-after-free in unix_stream_read_generic().
The following sequences reproduce the issue:
$ python3
from socket import *
s1, s2 = socketpair(AF_UNIX, SOCK_STREAM)
s1.send(b'x', MSG_OOB)
s2.recv(1, MSG_OOB) # leave a consumed OOB skb
s1.send(b'y', MSG_OOB)
s2.recv(1, MSG_OOB) # leave a consumed OOB skb
s1.send(b'z', MSG_OOB)
s2.recv(1) # recv 'z' illegally
s2.recv(1, MSG_OOB) # access 'z' skb (use-after-free)
Even though a user reads OOB data, the skb holding the data stays on
the recv queue to mark the OOB boundary and break the next recv().
After the last send() in the scenario above, the sk2's recv queue has
2 leading consumed OOB skbs and 1 real OOB skb.
Then, the following happens during the next recv() without MSG_OOB
1. unix_stream_read_generic() peeks the first consumed OOB skb
2. manage_oob() returns the next consumed OOB skb
3. unix_stream_read_generic() fetches the next not-yet-consumed OOB skb
4. unix_stream_read_generic() reads and frees the OOB skb
, and the last recv(MSG_OOB) triggers KASAN splat.
The 3. above occurs because of the SO_PEEK_OFF code, which does not
expect unix_skb_len(skb) to be 0, but this is true for such consumed
OOB skbs.
while (skip >= unix_skb_len(skb)) {
skip -= unix_skb_len(skb);
skb = skb_peek_next(skb, &sk->sk_receive_queue);
...
}
In addition to this use-after-free, there is another issue that
ioctl(SIOCATMARK) does not function properly with consecutive consumed
OOB skbs.
So, nothing good comes out of such a situation.
Instead of complicating manage_oob(), ioctl() handling, and the next
ECONNRESET fix by introducing a loop for consecutive consumed OOB skbs,
let's not leave such consecutive OOB unnecessarily.
Now, while receiving an OOB skb in unix_stream_recv_urg(), if its
previous skb is a consumed OOB skb, it is freed.

In some rare randconfig builds, I seem to trigger a bug in clang where
it unrolls a loop but then runs out of registers, which then get
spilled to the stack:
net/wireless/intel/iwlegacy/4965-rs.c:2262:1: error: stack frame size (1696) exceeds limit (1280) in 'il4965_rs_rate_init' [-Werror,-Wframe-larger-than]
This seems to be the same one I saw in the omapdrm driver, and there is
an easy workaround by not inlining the il4965_rs_rate_scale_clear_win
function.

Jerome Marchand says:
====================
bpf: Specify access type of bpf_sysctl_get_name args
The second argument of bpf_sysctl_get_name() helper is a pointer to a
buffer that is being written to. However that isn't specify in the
prototype. Until commit 37cce22dbd51a ("bpf: verifier: Refactor helper
access type tracking") that mistake was hidden by the way the verifier
treated helper accesses. Since then, the verifier, working on wrong
infromation from the prototype, can make faulty optimization that
would had been caught by the test_sysctl selftests if it was run by
the CI.
The first patch fixes bpf_sysctl_get_name prototype.
The second patch converts the test_sysctl to prog_tests so that it
will be run by the CI and catch similar issues in the future.
Changes in v3:
- Use ASSERT* macro instead of CHECK_FAIL.
- Remove useless code.
Changes in v2:
- Replace ARG_PTR_TO_UNINIT_MEM by ARG_PTR_TO_MEM | MEM_WRITE.
- Converts test_sysctl to prog_tests.

The second argument of bpf_sysctl_get_name() helper is a pointer to a
buffer that is being written to. However that isn't specify in the
prototype.
Until commit 37cce22dbd51a ("bpf: verifier: Refactor helper access
type tracking"), all helper accesses were considered as a possible
write access by the verifier, so no big harm was done. However, since
then, the verifier might make wrong asssumption about the content of
that address which might lead it to make faulty optimizations (such as
removing code that was wrongly labeled dead). This is what happens in
test_sysctl selftest to the tests related to sysctl_get_name.
Add MEM_WRITE flag the second argument of bpf_sysctl_get_name().

The bridge maintains a global list of ports behind which a multicast
router resides. The list is consulted during forwarding to ensure
multicast packets are forwarded to these ports even if the ports are not
member in the matching MDB entry.
When per-VLAN multicast snooping is enabled, the per-port multicast
context is disabled on each port and the port is removed from the global
router port list:
# ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1
# ip link add name dummy1 up master br1 type dummy
# ip link set dev dummy1 type bridge_slave mcast_router 2
$ bridge -d mdb show | grep router
router ports on br1: dummy1
# ip link set dev br1 type bridge mcast_vlan_snooping 1
$ bridge -d mdb show | grep router
However, the port can be re-added to the global list even when per-VLAN
multicast snooping is enabled:
# ip link set dev dummy1 type bridge_slave mcast_router 0
# ip link set dev dummy1 type bridge_slave mcast_router 2
$ bridge -d mdb show | grep router
router ports on br1: dummy1
Since commit 4b30ae9adb04 ("net: bridge: mcast: re-implement
br_multicast_{enable, disable}_port functions"), when per-VLAN multicast
snooping is enabled, multicast disablement on a port will disable the
per-{port, VLAN} multicast contexts and not the per-port one. As a
result, a port will remain in the global router port list even after it
is deleted. This will lead to a use-after-free [1] when the list is
traversed (when adding a new port to the list, for example):
# ip link del dev dummy1
# ip link add name dummy2 up master br1 type dummy
# ip link set dev dummy2 type bridge_slave mcast_router 2
Similarly, stale entries can also be found in the per-VLAN router port
list. When per-VLAN multicast snooping is disabled, the per-{port, VLAN}
contexts are disabled on each port and the port is removed from the
per-VLAN router port list:
# ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1 mcast_vlan_snooping 1
# ip link add name dummy1 up master br1 type dummy
# bridge vlan add vid 2 dev dummy1
# bridge vlan global set vid 2 dev br1 mcast_snooping 1
# bridge vlan set vid 2 dev dummy1 mcast_router 2
$ bridge vlan global show dev br1 vid 2 | grep router
router ports: dummy1
# ip link set dev br1 type bridge mcast_vlan_snooping 0
$ bridge vlan global show dev br1 vid 2 | grep router
However, the port can be re-added to the per-VLAN list even when
per-VLAN multicast snooping is disabled:
# bridge vlan set vid 2 dev dummy1 mcast_router 0
# bridge vlan set vid 2 dev dummy1 mcast_router 2
$ bridge vlan global show dev br1 vid 2 | grep router
router ports: dummy1
When the VLAN is deleted from the port, the per-{port, VLAN} multicast
context will not be disabled since multicast snooping is not enabled
on the VLAN. As a result, the port will remain in the per-VLAN router
port list even after it is no longer member in the VLAN. This will lead
to a use-after-free [2] when the list is traversed (when adding a new
port to the list, for example):
# ip link add name dummy2 up master br1 type dummy
# bridge vlan add vid 2 dev dummy2
# bridge vlan del vid 2 dev dummy1
# bridge vlan set vid 2 dev dummy2 mcast_router 2
Fix these issues by removing the port from the relevant (global or
per-VLAN) router port list in br_multicast_port_ctx_deinit(). The
function is invoked during port deletion with the per-port multicast
context and during VLAN deletion with the per-{port, VLAN} multicast
context.
Note that deleting the multicast router timer is not enough as it only
takes care of the temporary multicast router states (1 or 3) and not the
permanent one (2).

Change error values of `ionic_tx_map_single()` and `ionic_tx_map_frag()`
from 0 to `DMA_MAPPING_ERROR` to prevent collision with 0 as a valid
address.
This also fixes the use of `dma_mapping_error()` to test against 0 in
`ionic_xdp_post_frame()`

The mailbox controller driver for the Microchip Inter-processor
Communication can be built as a module. It uses cpuid_to_hartid_map and
commit 4783ce32b080 ("riscv: export __cpuid_to_hartid_map") enables that
to work for SMP. However, cpuid_to_hartid_map uses boot_cpu_hartid on
non-SMP kernels and this driver can be useful in such configurations[1].
Export boot_cpu_hartid so the driver can be built as a module on non-SMP
kernels as well.
