ext4: Fix warnings when freezing filesystem with journaled data
Test generic/390 in data=journal mode often triggers a warning that
ext4_do_writepages() tries to start a transaction on frozen filesystem.
This happens because although all dirty data is properly written, jbd2
checkpointing code writes data through submit_bh() and as a result only
buffer dirty bits are cleared but page dirty bits stay set. Later when
the filesystem is frozen, writeback code comes, tries to write
supposedly dirty pages and the warning triggers. Fix the problem by
calling sync_filesystem() once more after flushing the whole journal to
clear stray page dirty bits.

There is a problem with the behavior of hwlat in a container,
resulting in incorrect output. A warning message is generated:
"cpumask changed while in round-robin mode, switching to mode none",
and the tracing_cpumask is ignored. This issue arises because
the kernel thread, hwlatd, is not a part of the container, and
the function sched_setaffinity is unable to locate it using its PID.
Additionally, the task_struct of hwlatd is already known.
Ultimately, the function set_cpus_allowed_ptr achieves
the same outcome as sched_setaffinity, but employs task_struct
instead of PID.

# unshare --fork --pid bash -c 'echo 1 > tracing_on'

- Clear temporary storage in the resctrl code to prevent access to an
unexistent MSR
- Add a simple throttling mechanism to protect the hypervisor from
potentially malicious SEV guests issuing requests in rapid
succession.
In order to not jeopardize the sanity of everyone involved in
maintaining this code, the request issuing side has received a
cleanup, split in more or less trivial, small and digestible
pieces. Otherwise, the code was threatening to become an
unmaintainable mess.
Therefore, that cleanup is marked indirectly also for stable so
that there's no differences between the upstream code and the
stable variant when it comes down to backporting more there"

media: m5mols: fix off-by-one loop termination error
The __find_restype() function loops over the m5mols_default_ffmt[]
array, and the termination condition ends up being wrong: instead of
stopping when the iterator becomes the size of the array it traverses,
it stops after it has already overshot the array.
Now, in practice this doesn't likely matter, because the code will
always find the entry it looks for, and will thus return early and never
hit that last extra iteration.
But it turns out that clang will unroll the loop fully, because it has
only two iterations (well, three due to the off-by-one bug), and then
clang will end up just giving up in the middle of the loop unrolling
when it notices that the code walks past the end of the array.
And that made 'objtool' very unhappy indeed, because the generated code
just falls off the edge of the universe, and ends up falling through to
the next function, causing this warning:
drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc()
Fix the loop ending condition.

====================
bonding: properly restore flags when bond changes ether type
A bug was reported by syzbot[1] that causes a warning and a myriad of
other potential issues if a bond, that is also a slave, fails to enslave a
non-eth device. While fixing that bug I found that we have the same
issues when such enslave passes and after that the bond changes back to
ARPHRD_ETHER (again due to ether_setup). This set fixes all issues by
extracting the ether_setup() sequence in a helper which does the right
thing about bond flags when it needs to change back to ARPHRD_ETHER. It
also adds selftests for these cases.
Patch 01 adds the new bond_ether_setup helper and fixes the issues when a
bond device changes its ether type due to successful enslave. Patch 02
fixes the issues when it changes its ether type due to an unsuccessful
enslave. Note we need two patches because the bugs were introduced by
different commits. Patch 03 adds the new selftests.
Due to the comment adjustment and squash, could you please review
patch 01 again? I've kept the other acks since there were no code
changes.
v3: squash the helper patch and the first fix, adjust the comment above
it to be explicit about the bond device, no code changes
v2: new set, all patches are new due to new approach of fixing these bugs

selftests: bonding: add tests for ether type changes
Add new network selftests for the bonding device which exercise the ether
type changing call paths. They also test for the recent syzbot bug[1] which
causes a warning and results in wrong device flags (IFF_SLAVE missing).
The test adds three bond devices and a nlmon device, enslaves one of the
bond devices to the other and then uses the nlmon device for successful
and unsuccesful enslaves both of which change the bond ether type. Thus
we can test for both MASTER and SLAVE flags at the same time.
If the flags are properly restored we get:
TEST: Change ether type of an enslaved bond device with unsuccessful enslave [ OK ]
TEST: Change ether type of an enslaved bond device with successful enslave [ OK ]

bonding: restore bond's IFF_SLAVE flag if a non-eth dev enslave fails
syzbot reported a warning[1] where the bond device itself is a slave and
we try to enslave a non-ethernet device as the first slave which fails
but then in the error path when ether_setup() restores the bond device
it also clears all flags. In my previous fix[2] I restored the
IFF_MASTER flag, but I didn't consider the case that the bond device
itself might also be a slave with IFF_SLAVE set, so we need to restore
that flag as well. Use the bond_ether_setup helper which does the right
thing and restores the bond's flags properly.
Steps to reproduce using a nlmon dev:
$ ip l add nlmon0 type nlmon
$ ip l add bond1 type bond
$ ip l add bond2 type bond
$ ip l set bond1 master bond2
$ ip l set dev nlmon0 master bond1
$ ip -d l sh dev bond1
22: bond1: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noqueue master bond2 state DOWN mode DEFAULT group default qlen 1000
(now bond1's IFF_SLAVE flag is gone and we'll hit a warning[3] if we
try to delete it)

bonding: restore IFF_MASTER/SLAVE flags on bond enslave ether type change
Add bond_ether_setup helper which is used to fix ether_setup() calls in the
bonding driver. It takes care of both IFF_MASTER and IFF_SLAVE flags, the
former is always restored and the latter only if it was set.
If the bond enslaves non-ARPHRD_ETHER device (changes its type), then
releases it and enslaves ARPHRD_ETHER device (changes back) then we
use ether_setup() to restore the bond device type but it also resets its
flags and removes IFF_MASTER and IFF_SLAVE[1]. Use the bond_ether_setup
helper to restore both after such transition.
[1] reproduce (nlmon is non-ARPHRD_ETHER):
$ ip l add nlmon0 type nlmon
$ ip l add bond2 type bond mode active-backup
$ ip l set nlmon0 master bond2
$ ip l set nlmon0 nomaster
$ ip l add bond1 type bond
(we use bond1 as ARPHRD_ETHER device to restore bond2's mode)
$ ip l set bond1 master bond2
$ ip l sh dev bond2

The first changes the files included by "drivers/net/ipa/reg.h" to
ensure everything it requires is included with the file. It also
stops unnecessarily including another file. The prerequisites are
apparently satisfied other ways, currently.
The second adds two struct declarations to "gsi_reg.h", to ensure
they're declared before they're used later in the file. Again, it
seems these declarations are currently resolved wherever this file
is included.
The third removes register definitions that were added for IPA v5.0
that are not needed. And the last updates some validity checks for
IPA v5.0 registers. No IPA v5.0 platforms are yet supported, so the
issues resolved here were never harmful.
Versions 2 and 3 of this series change the "Fixes" tags in patches

net: dsa: microchip: fix RGMII delay configuration on KSZ8765/KSZ8794/KSZ8795
The blamed commit has replaced a ksz_write8() call to address
REG_PORT_5_CTRL_6 (0x56) with a ksz_set_xmii() -> ksz_pwrite8() call to
regs[P_XMII_CTRL_1], which is also defined as 0x56 for ksz8795_regs[].
The trouble is that, when compared to ksz_write8(), ksz_pwrite8() also
adjusts the register offset with the port base address. So in reality,
ksz_pwrite8(offset=0x56) accesses register 0x56 + 0x50 = 0xa6, which in
this switch appears to be unmapped, and the RGMII delay configuration on
the CPU port does nothing.
So if the switch wasn't fine with the RGMII delay configuration done
through pin strapping and relied on Linux to apply a different one in
order to pass traffic, this is now broken.
Using the offset translation logic imposed by ksz_pwrite8(), the correct
value for regs[P_XMII_CTRL_1] should have been 0x6 on ksz8795_regs[], in
order to really end up accessing register 0x56.
Static code analysis shows that, despite there being multiple other
accesses to regs[P_XMII_CTRL_1] in this driver, the only code path that
is applicable to ksz8795_regs[] and ksz8_dev_ops is ksz_set_xmii().
Therefore, the problem is isolated to RGMII delays.
In its current form, ksz8795_regs[] contains the same value for
P_XMII_CTRL_0 and for P_XMII_CTRL_1, and this raises valid suspicions
that writes made by the driver to regs[P_XMII_CTRL_0] might overwrite
writes made to regs[P_XMII_CTRL_1] or vice versa.
Again, static analysis shows that the only accesses to P_XMII_CTRL_0
from the driver are made from code paths which are not reachable with
ksz8_dev_ops. So the accesses made by ksz_set_xmii() are safe for this
switch family.

hsr: ratelimit only when errors are printed
Recently, when automatically merging -net and net-next in MPTCP devel
tree, our CI reported [1] a conflict in hsr, the same as the one
reported by Stephen in netdev [2].
When looking at the conflict, I noticed it is in fact the v1 [3] that
has been applied in -net and the v2 [4] in net-next. Maybe the v1 was
applied by accident.
As mentioned by Jakub Kicinski [5], the new condition makes more sense
before the net_ratelimit(), not to update net_ratelimit's state which is
unnecessary if we're not going to print either way.
Here, this modification applies the v2 but in -net.

selftests: net: devlink_port_split.py: skip test if no suitable device available
The `devlink -j port show` command output may not contain the "flavour"
key, an example from Ubuntu 22.10 s390x LPAR(5.19.0-37-generic), with
mlx4 driver and iproute2-5.15.0:
{"port":{"pci/0001:00:00.0/1":{"type":"eth","netdev":"ens301"},
"pci/0001:00:00.0/2":{"type":"eth","netdev":"ens301d1"},

"pci/0002:00:00.0/2":{"type":"eth","netdev":"ens317d1"}}}
This will cause a KeyError exception.
Create a validate_devlink_output() to check for this "flavour" from
devlink command output to avoid this KeyError exception. Also let
it handle the check for `devlink -j dev show` output in main().
Apart from this, if the test was not started because the max lanes of
the designated device is 0. The script will still return 0 and thus
causing a false-negative test result.
Use a found_max_lanes flag to determine if these tests were skipped
due to this reason and return KSFT_SKIP to make it more clear.

net: atlantic: Fix crash when XDP is enabled but no program is loaded
The aq_xdp_run_prog() function falls back to the XDP_ABORTED action
handler (using a goto) if the operations for any of the other actions fail.
The XDP_ABORTED handler in turn calls the bpf_warn_invalid_xdp_action()
tracepoint. However, the function also jumps into the XDP_PASS helper if no
XDP program is loaded on the device, which means the XDP_ABORTED handler
can be run with a NULL program pointer. This results in a NULL pointer
deref because the tracepoint dereferences the 'prog' pointer passed to it.
This situation can happen in multiple ways:
- If a packet arrives between the removal of the program from the interface
and the static_branch_dec() in aq_xdp_setup()
- If there are multiple devices using the same driver in the system and
one of them has an XDP program loaded and the other does not.
Fix this by refactoring the aq_xdp_run_prog() function to remove the 'goto
pass' handling if there is no XDP program loaded. Instead, factor out the
skb building in a separate small helper function.
