On sa8775p the MAC is connected to the external PHY over SGMII so add
support for it to the driver.

In preparation for supporting SGMII, let's make the code a bit more
generic. Add a new callback for MAC configuration so that we can assign
a different variant of it in the future.

On sa8775p, the EMAC revision is 4 and we use SGMII instead of RGMII.
There's no "rgmii" clock but there's a fourth clock under a different
name: "phyaux". Add a new field to the chip data struct that specifies
the link clock name. Default to "rgmii" for backward compatibility.

The text has been cut/paste from genphy_c45_ethtool_get_eee but not
changed to reflect it performs set.
Additionally, extend the comment. This function implements the logic
that eee_enabled has global control over EEE. When eee_enabled is
false, no link modes will be advertised, and as a result, the MAC
should not transmit LPI.

The reverted commit was also removing a comment about

Blamed commit added these helpers for sake of detecting RAW
sockets specific ioctl.
syzbot complained about it [1].
Issue here is that RAW sockets could pretend there was no need
to call ipmr_sk_ioctl()
Regardless of inet_sk(sk)->inet_num, we must be prepared
for ipmr_ioctl() being called later. This must happen
from ipmr_sk_ioctl() context only.
We could add a safety check in ipmr_ioctl() at the risk of breaking
applications.
Instead, remove sk_is_ipmr() and sk_is_icmpv6() because their
name would be misleading, once we change their implementation.

Have the user events automatically get removed when the last

prevent leaks of user events hanging around needing admins to
clean them up.
- Add persistent logic (but not let user space use it yet)
In some cases, having a persistent user event (one that does not
get cleaned up automatically) is useful. But there's still debates
about how to expose this to user space. The infrastructure is

"One more regression fix for an assertion failure that uncovered a
nasty problem with stripe calculations. This is caused by a u32
overflow when there are enough devices. The fstests require 6 so this
hasn't been caught, I was able to hit it with 8.
The fix is minimal and only adds u64 casts, we'll clean that up later.

When deleting a base chain, iptables-nft simply submits the whole chain
to the kernel, including the NFTA_CHAIN_HOOK attribute. The new code
added by fixed commit then turned this into a chain update, destroying
the hook but not the chain itself. Detect the situation by checking if
the chain type is either netdev or inet/ingress.

Add bound flag to rule and chain transactions as in 6a0a8d10a366
("netfilter: nf_tables: use-after-free in failing rule with bound set")
to skip them in case that the chain is already bound from the abort
path.
This patch fixes an imbalance in the chain use refcnt that triggers a
WARN_ON on the table and chain destroy path.
This patch also disallows nested chain bindings, which is not
supported from userspace.
The logic to deal with chain binding in nft_data_hold() and
nft_data_release() is not correct. The NFT_TRANS_PREPARE state needs a
special handling in case a chain is bound but next expressions in the
same rule fail to initialize as described by 1240eb93f061 ("netfilter:
nf_tables: incorrect error path handling with NFT_MSG_NEWRULE").
The chain is left bound if rule construction fails, so the objects
stored in this chain (and the chain itself) are released by the
transaction records from the abort path, follow up patch ("netfilter:
nf_tables: add NFT_TRANS_PREPARE_ERROR to deal with bound set/chain")
completes this error handling.
When deleting an existing rule, chain bound flag is set off so the
rule expression .destroy path releases the objects.

The max_raw_write member of the regmap_spi_avmm_bus structure is defined
as:
.max_raw_write = SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT
SPI_AVMM_VAL_SIZE == 4 and MAX_WRITE_CNT == 1 so this results in a
maximum write transfer size of 4 bytes which provides only enough space to
transfer the address of the target register. It provides no space for the
value to be transferred. This bug became an issue (divide-by-zero in
_regmap_raw_write()) after the following was accepted into mainline:
commit 3981514180c9 ("regmap: Account for register length when chunking")
Change max_raw_write to include space (4 additional bytes) for both the
register address and value:
.max_raw_write = SPI_AVMM_REG_SIZE + SPI_AVMM_VAL_SIZE * MAX_WRITE_CNT

If an AF_ALG socket bound to a hashing algorithm is sent a zero-length
message with MSG_MORE set and then recvmsg() is called without first
sending another message without MSG_MORE set to end the operation, an oops
will occur because the crypto context and result doesn't now get set up in
advance because hash_sendmsg() now defers that as long as possible in the
hope that it can use crypto_ahash_digest() - and then because the message
is zero-length, it the data wrangling loop is skipped.
Fix this by handling zero-length sends at the top of the hash_sendmsg()
function. If we're not continuing the previous sendmsg(), then just ignore
the send (hash_recvmsg() will invent something when called); if we are
continuing, then we finalise the request at this point if MSG_MORE is not
set to get any error here, otherwise the send is of no effect and can be
ignored.
Whilst we're at it, remove the code to create a kvmalloc'd scatterlist if
we get more than ALG_MAX_PAGES - this shouldn't happen.

The new phy driver attempts to select a driver from another subsystem,

I could not see an actual compile time dependency, so presumably this
is only needed for for working correctly but not technically a dependency
on that particular nvmem driver implementation, so it would likely
be safe to remove the select for compile testing.
To keep the spirit of the original 'select', just replace this with a
'depends on' that ensures that the driver will work but does not get in
the way of build testing.

[CAUSE]
Commit a97699d1d610 ("btrfs: replace map_lookup->stripe_len by
BTRFS_STRIPE_LEN") changes how we calculate the map length, to reduce
u64 division.
Function btrfs_max_io_len() is to get the length to the stripe boundary.
It calculates the full stripe start offset (inside the chunk) by the
following code:
*full_stripe_start =
rounddown(*stripe_nr, nr_data_stripes(map)) <<
BTRFS_STRIPE_LEN_SHIFT;
The calculation itself is fine, but the value returned by rounddown() is
dependent on both @stripe_nr (which is u32) and nr_data_stripes() (which
returned int).
Thus the result is also u32, then we do the left shift, which can
overflow u32.
If such overflow happens, @full_stripe_start will be a value way smaller
than @offset, causing later "full_stripe_len - (offset -
*full_stripe_start)" to underflow, thus make later length calculation to
have no stripe boundary limit, resulting a write bio to exceed stripe
boundary.
There are some other locations like this, with a u32 @stripe_nr got left
shift, which can lead to a similar overflow.
[FIX]
Fix all @stripe_nr with left shift with a type cast to u64 before the
left shift.
Those involved @stripe_nr or similar variables are recording the stripe
number inside the chunk, which is small enough to be contained by u32,
but their offset inside the chunk can not fit into u32.
Thus for those specific left shifts, a type cast to u64 is necessary so
this patch does not touch them and the code will be cleaned up in the
future to keep the fix minimal.

v6:
- Change a small portion of the comment in the diff on "net: dsa: mt7530:
set all CPU ports in MT7531_CPU_PMAP" with Russell's suggestion.
- Change the patch log of "net: dsa: mt7530: fix trapping frames on
non-MT7621 SoC MT7530 switch" with Vladimir's suggestion.
- Group the code for trapping frames into a common function and call that.
- Add Vladimir and Russell's reviewed-by tags to where they're given.
v5:
- Change the comment in the diff on the first patch with Russell's words.
- Change the patch log of the first patch to state that the patch is just
preparatory work for change "net: dsa: introduce
preferred_default_local_cpu_port and use on MT7530" and not a fix to an
existing problem on the code base.
- Remove the "net: dsa: mt7530: fix trapping frames with multiple CPU ports
on MT7530" patch. It fixes a theoretical issue, therefore it is net-next
material.
- Remove unnecessary information from the patch logs. Remove the enum
renaming change.
- Strengthen the point of the "net: dsa: introduce
preferred_default_local_cpu_port and use on MT7530" patch.
v4: Make the patch logs and my comments in the code easier to understand.
v3: Fix the from header on the patches. Write a cover letter.
v2: Add patches to fix the handling of LLDP frames and BPDUs.
