In bcm_sf2_mdio_register(), the class_find_device() will call get_device()
to increment reference count for priv->master_mii_bus->dev if
of_mdio_find_bus() succeeds. If mdiobus_alloc() or mdiobus_register()
fails, it will call get_device() twice without decrement reference count
for the device. And it is the same if bcm_sf2_mdio_register() succeeds but
fails in bcm_sf2_sw_probe(), or if bcm_sf2_sw_probe() succeeds. If the
reference count has not decremented to zero, the dev related resource will
not be freed.
So remove the get_device() in bcm_sf2_mdio_register(), and call
put_device() if mdiobus_alloc() or mdiobus_register() fails and in
bcm_sf2_mdio_unregister() to solve the issue.
And as Simon suggested, unwind from errors for bcm_sf2_mdio_register() and
just return 0 if it succeeds to make it cleaner.

The tests rely on the IPv{4,6} FIB trace points being triggered once for
each forwarded packet. If receive processing is deferred to the
ksoftirqd task these invocations will not be counted and the tests will
fail. Fix by specifying the '-a' flag to avoid perf from filtering on
the mausezahn task.

The test relies on the fib:fib_table_lookup trace point being triggered
once for each forwarded packet. If RP filter is not disabled, the trace
point will be triggered twice for each packet (for source validation and
forwarding), potentially masking actual bugs. Fix by explicitly
disabling RP filter.

syzbot reported a warning [0] introduced by commit c48ef9c4aed3 ("tcp: Fix
bind() regression for v4-mapped-v6 non-wildcard address.").
After the cited commit, a v4 socket's address matches the corresponding
v4-mapped-v6 tb2 in inet_bind2_bucket_match_addr(), not vice versa.
During X.X.X.X -> ::ffff:X.X.X.X order bind()s, the second bind() uses
bhash and conflicts properly without checking bhash2 so that we need not
check if a v4-mapped-v6 sk matches the corresponding v4 address tb2 in
inet_bind2_bucket_match_addr(). However, the repro shows that we need
to check that in a no-conflict case.
The repro bind()s two sockets to the 2-tuples using SO_REUSEPORT and calls
listen() for the first socket:
from socket import *
s1 = socket()
s1.setsockopt(SOL_SOCKET, SO_REUSEPORT, 1)
s1.bind(('127.0.0.1', 0))
s2 = socket(AF_INET6)
s2.setsockopt(SOL_SOCKET, SO_REUSEPORT, 1)
s2.bind(('::ffff:127.0.0.1', s1.getsockname()[1]))
s1.listen()
The second socket should belong to the first socket's tb2, but the second
bind() creates another tb2 bucket because inet_bind2_bucket_find() returns
NULL in inet_csk_get_port() as the v4-mapped-v6 sk does not match the
corresponding v4 address tb2.
bhash2[] -> tb2(::ffff:X.X.X.X) -> tb2(X.X.X.X)
Then, listen() for the first socket calls inet_csk_get_port(), where the
v4 address matches the v4-mapped-v6 tb2 and WARN_ON() is triggered.
To avoid that, we need to check if v4-mapped-v6 sk address matches with
the corresponding v4 address tb2 in inet_bind2_bucket_match().
The same checks are needed in inet_bind2_bucket_addr_match() too, so we
can move all checks there and call it from inet_bind2_bucket_match().
Note that now tb->family is just an address family of tb->(v6_)?rcv_saddr
and not of sockets in the bucket. This could be refactored later by
defining tb->rcv_saddr as tb->v6_rcv_saddr.s6_addr32[3] and prepending
::ffff: when creating v4 tb2.

Since 429e3d123d9a ("bonding: Fix extraction of ports from the packet
headers"), header offsets used to compute a hash in bond_xmit_hash() are
relative to skb->data and not skb->head. If the tail of the header buffer
of an skb really needs to be advanced and the operation is successful, the
pointer to the data must be returned (and not a pointer to the head of the
buffer).

Sergei Trofimovich reported a regression [0] caused by commit a0ade8404c3b
("af_packet: Fix warning of fortified memcpy() in packet_getname().").
It introduced a flex array sll_addr_flex in struct sockaddr_ll as a
union-ed member with sll_addr to work around the fortified memcpy() check.
However, a userspace program uses a struct that has struct sockaddr_ll in
the middle, where a flex array is illegal to exist.
include/linux/if_packet.h:24:17: error: flexible array member 'sockaddr_ll::<unnamed union>::<unnamed struct>::sll_addr_flex' not at end of 'struct packet_info_t'

To fix the regression, let's go back to the first attempt [1] telling
memcpy() the actual size of the array.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and

SMC_STAT_PAYLOAD_SUB(_smc_stats, _tech, key, _len, _rc) will calculate
wrong bucket positions for payloads of exactly 4096 bytes and
(1 << (m + 12)) bytes, with m == SMC_BUF_MAX - 1.
Intended bucket distribution:
Assume l == size of payload, m == SMC_BUF_MAX - 1.
Bucket 0 : 0 < l <= 2^13
Bucket n, 1 <= n <= m-1 : 2^(n+12) < l <= 2^(n+13)
Bucket m : l > 2^(m+12)
Current solution:
_pos = fls64((l) >> 13)
[...]
_pos = (_pos < m) ? ((l == 1 << (_pos + 12)) ? _pos - 1 : _pos) : m
For l == 4096, _pos == -1, but should be _pos == 0.
For l == (1 << (m + 12)), _pos == m, but should be _pos == m - 1.
In order to avoid special treatment of these corner cases, the
calculation is adjusted. The new solution first subtracts the length by
one, and then calculates the correct bucket by shifting accordingly,
i.e. _pos = fls64((l - 1) >> 13), l > 0.
This not only fixes the issues named above, but also makes the whole
bucket assignment easier to follow.
Same is done for SMC_STAT_RMB_SIZE_SUB(_smc_stats, _tech, k, _len),
where the calculation of the bucket position is similar to the one
named above.

A bitset without mask in a _SET request means we want exactly the bits in
the bitset to be set. This works correctly for compact format but when
verbose format is parsed, ethnl_update_bitset32_verbose() only sets the
bits present in the request bitset but does not clear the rest. The commit
6699170376ab fixes this issue by clearing the whole target bitmap before we
start iterating. The solution proposed brought an issue with the behavior
of the mod variable. As the bitset is always cleared the old val will
always differ to the new val.
Fix it by adding a new temporary variable which save the state of the old
bitmap.

Our current route lookups (mctp_route_lookup and mctp_route_lookup_null)
traverse the net's route list without the RCU read lock held. This means
the route lookup is subject to preemption, resulting in an potential
grace period expiry, and so an eventual kfree() while we still have the
route pointer.
Add the proper read-side critical section locks around the route
lookups, preventing premption and a possible parallel kfree.
The remaining net->mctp.routes accesses are already under a
rcu_read_lock, or protected by the RTNL for updates.
Based on an analysis from Sili Luo <rootlab@huawei.com>, where
introducing a delay in the route lookup could cause a UAF on

When functions called by the trampoline panic, the backtrace that is

One of the first things that s390x kernel functions do is storing the
the caller's frame address (backchain) on stack. This makes unwinding
possible. The backchain is always stored at frame offset 152, which is
inside the 160-byte stack area, that the functions allocate for their
callees. The callees must preserve the backchain; the remaining 152
bytes they may use as they please.
Currently the trampoline uses all 160 bytes, clobbering the backchain.
This causes kernel panics when using __builtin_return_address() in
functions called by the trampoline.
Fix by reducing the usage of the caller-reserved stack area by 8 bytes
in the trampoline.

security perspective. Hence switch to use indirect function calls instead.
Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

Also note that commit 5873d380f4c0 ("irqchip/qcom-pdc: Add support for
v3.2 HW") has a incorrect SOB chain.
The real author is Neil. His patch was posted by Dmitry once and Neil
picked it up from the list and reposted it with the bogus SOB chain.
Not a big deal, but worth to mention. I wanted to fix that up, but
then got distracted and Marc piled more changes on top. So I decided
to leave it as is instead of rebasing world"

This reverts commit 5f521494cc73520ffac18ede0758883b9aedd018.
The patch breaks mounts with security mount options like
$ mount -o context=system_u:object_r:root_t:s0 /dev/sdX /mn
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdX, missing codepage or helper program, ...
We cannot reject all unknown options in btrfs_parse_subvol_options() as
intended, the security options can be present at this point and it's not
possible to enumerate them in a future proof way. This means unknown
mount options are silently accepted like before when the filesystem is
mounted with either -o subvol=/path or as followup mounts of the same
device.

Commit 1e66220948df8 ("net/mlx5e: Update rx ring hw mtu upon each rx-fcs
flag change") seems to have accidentally inverted the logic added in
commit 0bc73ad46a76 ("net/mlx5e: Mutually exclude RX-FCS and
RX-port-timestamp").
The impact of this is a little unclear since it seems the FCS scattered
with RX-FCS is (usually?) correct regardless.

When the SMC protocol is built into the kernel proper while ISM is
configured to be built as module, linking the kernel fails due to
unresolved dependencies out of net/smc/smc_ism.o to
ism_get_smcd_ops, ism_register_client, and ism_unregister_client
as reported via the linux-next test automation (see link).
This however is a bug introduced a while ago.
Correct the dependency list in ISM's and SMC's Kconfig to reflect the
dependencies that are actually inverted. With this you cannot build a
kernel with CONFIG_SMC=y and CONFIG_ISM=m. Either ISM needs to be 'y',
too - or a 'n'. That way, SMC can still be configured on non-s390
architectures that do not have (nor need) an ISM driver.

When updating the SA, use the new update_pn flags instead of comparing the
new PN with the initial one.
Comparing the initial PN value with the new value will allow the user
to update the SA using the initial PN value as a parameter like this:
