====================
Netfilter updates for net-next
1) Move struct nft_payload_set definition to .c file where it is
only used.
2) Shrink transport and inner header offset fields in the nft_pktinfo
structure to 16-bits, from Florian Westphal.
3) Get rid of nft_objref Kbuild toggle, make it built-in into
nf_tables. This expression is used to instantiate conntrack helpers
in nftables. After removing the conntrack helper auto-assignment
toggle it this feature became more important so move it to the nf_tables
core module. Also from Florian.
4) Extend the existing function to calculate payload inner header offset
to deal with the GRE and IPIP transport protocols.
6) Add inner expression support for nf_tables. This new expression
provides a packet parser for tunneled packets which uses a userspace
description of the expected inner headers. The inner expression
invokes the payload expression (via direct call) to match on the
inner header protocol fields using the inner link, network and
transport header offsets.
An example of the bytecode generated from userspace to match on
IP source encapsulated in a VxLAN packet:
# nft --debug=netlink add rule netdev x y udp dport 4789 vxlan ip saddr 1.2.3.4
netdev x y
[ meta load l4proto => reg 1 ]
[ cmp eq reg 1 0x00000011 ]
[ payload load 2b @ transport header + 2 => reg 1 ]
[ cmp eq reg 1 0x0000b512 ]
[ inner type vxlan hdrsize 8 flags f [ meta load protocol => reg 1 ] ]
[ cmp eq reg 1 0x00000008 ]
[ inner type vxlan hdrsize 8 flags f [ payload load 4b @ network header + 12 => reg 1 ] ]
[ cmp eq reg 1 0x04030201 ]
7) Store inner link, network and transport header offsets in percpu
area to parse inner packet header once only. Matching on a different
tunnel type invalidates existing offsets in the percpu area and it
invokes the inner tunnel parser again.
8) Add support for inner meta matching. This support for
NFTA_META_PROTOCOL, which specifies the inner ethertype, and
NFT_META_L4PROTO, which specifies the inner transport protocol.
9) Extend nft_inner to parse GENEVE optional fields to calculate the
link layer offset.
10) Update inner expression so tunnel offset points to GRE header
to normalize tunnel header handling. This also allows to perform
different interpretations of the GRE header from userspace.

When expanding a file system using online resize, various fields in
the superblock (e.g., s_blocks_count, s_inodes_count, etc.) change.
To update the backup superblocks, the online resize uses the function
update_backups() in fs/ext4/resize.c. This function was not updating
the checksum field in the backup superblocks. This wasn't a big deal
previously, because e2fsck didn't care about the checksum field in the
backup superblock. (And indeed, update_backups() goes all the way
back to the ext3 days, well before we had support for metadata
checksums.)
However, there is an alternate, more general way of updating
superblock fields, ext4_update_primary_sb() in fs/ext4/ioctl.c. This
function does check the checksum of the backup superblock, and if it
doesn't match will mark the file system as corrupted. That was
clearly not the intent, so avoid to aborting the resize when a bad
superblock is found.
In addition, teach update_backups() to properly update the checksum in
the backup superblocks. We will eventually want to unify
updapte_backups() with the infrasture in ext4_update_primary_sb(), but
that's for another day.
Note: The problem has been around for a while; it just didn't really
matter until ext4_update_primary_sb() was added by commit bbc605cdb1
("ext4: implement support for get/set fs label"). And it became
trivially easy to reproduce after commit 827891a38a ("ext4: update

However, the core->parent pointer might be NULL because the clock is

then call a determine_rate variant with that unitialized structure.

If a clock has CLK_SET_RATE_PARENT, but core->parent is NULL (most
likely because it's orphan), callers of clk_core_init_rate_req() will
blindly call this function leading to a very verbose warning.
Since it's a fairly common situation, let's just remove the WARN_ON but
keep the check that prevents us from dereferencing the pointer.
Interestingly, it fixes a regression on the Mediatek MT8195 where the
GPU would stall during a clk_set_rate for its main clock. We couldn't
come up with a proper explanation since the condition is essentially the
same.
It was then assumed that it could be timing related since printing the
warning stacktrace takes a while, but we couldn't replicate the failure
by using fairly large (10ms) mdelays.

This came up due to a report from Kevin @ kernel-ci, who had been
running a mixed configuration of GNU binutils and clang. Their compiler
was relatively recent & supports Zicbom but binutils @ 2.35.2 did not.
Our current checks for extension support only cover the compiler, but it
appears to me that we need to check both the compiler & linker support
in case of "pot-luck" configurations that mix different versions of
LD,AS,CC etc.
Linker support does not seem possible to actually check, since the ISA
string is emitted into the object files - so I put in version checks for
that. The checks have gotten a bit ugly since 32 & 64 bit support need
to be checked independently but ahh well.
As I was going, I fell into the trap of there being duplicated checks
for CC support in both the Makefile and Kconfig, so as part of renaming
the Kconfig symbol to TOOLCHAIN_HAS_FOO, I dropped the extra checks in
the Makefile. This has the added advantage of the TOOLCHAIN_HAS_FOO
symbol for Zihintpause appearing in .config.
I pushed out a version of this that specificly checked for assember
support for LKP to test & it looked /okay/ - but I did some more testing
today and realised that this is redudant & have since dropped the as
check.
I tested locally with a fair few different combinations, to try and
cover each of AS, LD, CC missing support for the extension.

The PMU on T-Head C9xx cores is quite similar to the SSCOFPMF extension

drivers/perf: riscv_pmu_sbi: add support for PMU variant on T-Head C9xx cores
RISC-V: Cache SBI vendor values
With the T-HEAD C9XX cores being designed before or during the ratification
to the SSCOFPMF extension, it implements functionality very similar but
not equal to it.
It implements overflow handling and also some privilege-mode filtering.
While SSCOFPMF supports this for all modes, the C9XX only implements the
filtering for M-mode and S-mode but not user-mode.
So add some adaptions to allow the C9XX to still handle
its PMU through the regular SBI PMU interface instead of defining new
interfaces or drivers.
To work properly, this requires a matching change in SBI, though the actual
interface between kernel and SBI does not change.
The main differences are a the overflow CSR and irq number.
As the reading of the overflow-csr is in the hot-path during irq handling,
use an errata and alternatives to not introduce new conditionals there.

sbi_get_mvendorid(), sbi_get_marchid() and sbi_get_mimpid() might get
called multiple times, though the values of these CSRs should not change
during the runtime of a specific machine.
Though the values can be different depending on which hart of the system
they get called. So hook into the newly introduced cpuinfo struct to allow
retrieving these cached values via new functions.
Also use arch_initcall for the cpuinfo setup instead, as that now clearly
is "architecture specific initialization" and also makes these information
available slightly earlier.

When holding a delegation, the NFS client optimizes away setting the
attributes of a file from the GETATTR in the compound after CLONE, and for
a zero-length CLONE we will end up setting the inode's size to zero in
nfs42_copy_dest_done(). Handle this case by computing the resulting count
from the server's reported size after CLONE's GETATTR.

There's a small window where a LOCK sent during a delegation return can
race with another OPEN on client, but the open stateid has not yet been
updated. In this case, the client doesn't handle the OLD_STATEID error
from the server and will lose this lock, emitting:
"NFS: nfs4_handle_delegation_recall_error: unhandled error -10024".
Fix this by sending the task through the nfs4 error handling in
nfs4_lock_done() when we may have to reconcile our stateid with what the
server believes it to be. For this case, the result is a retry of the
LOCK operation with the updated stateid.
