Pull random number generator updates from Jason Donenfeld:
"These a bit more numerous than usual for the RNG, due to folks
resubmitting patches that had been pending prior and generally renewed
interest.
There are a few categories of patches in here:
1) Dominik Brodowski and I traded a series back and forth for a some
weeks that fixed numerous issues related to seeds being provided
at extremely early boot by the firmware, before other parts of the
kernel or of the RNG have been initialized, both fixing some
crashes and addressing correctness around early boot randomness.
One of these is marked for stable.
2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
extractor, and made the construction a bit safer and more
standard. This was sort of a long overdue low hanging fruit, as we
were supposed to have phased out SHA-1 usage quite some time ago
(even if all we needed here was non-invertibility). Along the way
it also made extraction 131% faster. This required a bit of
Kconfig and symbol plumbing to make things work well with the
crypto libraries, which is one of the reasons why I'm sending you
this pull early in the cycle.
3) I got rid of a truly superfluous call to RDRAND in the hot path,
which resulted in a whopping 370% increase in performance.
4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
the full series of which wasn't ready yet, but the first two
preparatory cleanups were good on their own. One of them touches
files in kernel/irq/, which is the other reason why I'm sending
you this pull early in the cycle.
5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
Mark Brown, Dominik Brodowski, and myself"

Implement support for FS_IOC_GETFSLABEL and FS_IOC_SETFSLABEL ioctls for
online reading and setting of file system label.
ext4_ioctl_getlabel() is simple, just get the label from the primary
superblock. This might not be the first sb on the file system if
'sb=' mount option is used.
In ext4_ioctl_setlabel() we update what ext4 currently views as a
primary superblock and then proceed to update backup superblocks. There
are two caveats:
- the primary superblock might not be the first superblock and so it
might not be the one used by userspace tools if read directly
off the disk.
- because the primary superblock might not be the first superblock we
potentialy have to update it as part of backup superblock update.
However the first sb location is a bit more complicated than the rest
so we have to account for that.
The superblock modification is created generic enough so the
infrastructure can be used for other potential superblock modification
operations, such as chaning UUID.
Tested with generic/492 with various configurations. I also checked the
behavior with 'sb=' mount options, including very large file systems
with and without sparse_super/sparse_super2.

Pull ARM SoC devicetree updates from Arnd Bergmann:
"As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms. All the
newly supported SoCs belong into existing families this time:
- Qualcomm gets support for two newly announced platforms, both of
which can now work in production environments: the SDX65 5G modem
that can run a minimal Linux on its Cortex-A7 core, and the
Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3 family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two new
SoCs, plus a number of Chromebook variants and phones based on the
Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit chips
out of the box, including a number of ASUS Transformer tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top box
based on the H6 SoC.

Jan 08 13:50:27 oracle-102.nfsv4.dev kernel: BUG: KASAN: stack-out-of-bounds in trace_event_raw_event_svc_xprt_create_err+0x190/0x210 [sunrpc]
Jan 08 13:50:27 oracle-102.nfsv4.dev kernel: Read of size 28 at addr ffffc9000008f728 by task mount.nfs/4628
The memcpy() in the TP_fast_assign section of this trace point
copies the size of the destination buffer in order that the buffer
won't be overrun.
In other similar trace points, the source buffer for this memcpy is
a "struct sockaddr_storage" so the actual length of the source
buffer is always long enough to prevent the memcpy from reading
uninitialized or unallocated memory.
However, for this trace point, the source buffer can be as small as
a "struct sockaddr_in". For AF_INET sockaddrs, the memcpy() reads
memory that follows the source buffer, which is not always valid
memory.
To avoid copying past the end of the passed-in sockaddr, make the
source address's length available to the memcpy(). It would be a
little nicer if the tracing infrastructure was more friendly about
storing socket addresses that are not AF_INET, but I could not find
a way to make printk("%pIS") work with a dynamic array.

Move NFS to using fscache DIO API instead of the old upstream I/O API as
that has been removed. This is a stopgap solution as the intention is that
at sometime in the future, the cache will move to using larger blocks and
won't be able to store individual pages in order to deal with the potential
for data corruption due to the backing filesystem being able insert/remove
bridging blocks of zeros into its extent list[1].
NFS then reads and writes cache pages synchronously and one page at a time.
The preferred change would be to use the netfs lib, but the new I/O API can
be used directly. It's just that as the cache now needs to track data for
itself, caching blocks may exceed page size...
This code is somewhat borrowed from my "fallback I/O" patchset[2].

Change the nfs filesystem to support fscache's indexing rewrite and
reenable caching in nfs.
The following changes have been made:
(1) The fscache_netfs struct is no more, and there's no need to register
the filesystem as a whole.
(2) The session cookie is now an fscache_volume cookie, allocated with
fscache_acquire_volume(). That takes three parameters: a string
representing the "volume" in the index, a string naming the cache to
use (or NULL) and a u64 that conveys coherency metadata for the
volume.
For nfs, I've made it render the volume name string as:
"nfs,<ver>,<family>,<address>,<port>,<fsidH>,<fsidL>*<,param>[,<uniq>]"
(3) The fscache_cookie_def is no more and needed information is passed
directly to fscache_acquire_cookie(). The cache no longer calls back
into the filesystem, but rather metadata changes are indicated at
other times.
fscache_acquire_cookie() is passed the same keying and coherency
information as before.
(4) fscache_enable/disable_cookie() have been removed.
Call fscache_use_cookie() and fscache_unuse_cookie() when a file is
opened or closed to prevent a cache file from being culled and to keep
resources to hand that are needed to do I/O.
If a file is opened for writing, we invalidate it with
FSCACHE_INVAL_DIO_WRITE in lieu of doing writeback to the cache,
thereby making it cease caching until all currently open files are
closed. This should give the same behaviour as the uptream code.
Making the cache store local modifications isn't straightforward for
NFS, so that's left for future patches.
(5) fscache_invalidate() now needs to be given uptodate auxiliary data and
a file size. It also takes a flag to indicate if this was due to a
DIO write.
(6) Call nfs_fscache_invalidate() with FSCACHE_INVAL_DIO_WRITE on a file
to which a DIO write is made.
(7) Call fscache_note_page_release() from nfs_release_page().
(8) Use a killable wait in nfs_vm_page_mkwrite() when waiting for
PG_fscache to be cleared.
(9) The functions to read and write data to/from the cache are stubbed out
pending a conversion to use netfslib.
Changes
=======
ver #3:
- Added missing =n fallback for nfs_fscache_release_file()[1][2].
ver #2:
- Use gfpflags_allow_blocking() rather than using flag directly.
- fscache_acquire_volume() now returns errors.
- Remove NFS_INO_FSCACHE as it's no longer used.
- Need to unuse a cookie on file-release, not inode-clear.

Netfilter conntrack maintains NAT flags per connection indicating
whether NAT was configured for the connection. Openvswitch maintains
NAT flags on the per packet flow key ct_state field, indicating
whether NAT was actually executed on the packet.
When a packet misses from tc to ovs the conntrack NAT flags are set.
However, NAT was not necessarily executed on the packet because the
connection's state might still be in NEW state. As such, openvswitch
wrongly assumes that NAT was executed and sets an incorrect flow key
NAT flags.
Fix this, by flagging to openvswitch which NAT was actually done in
act_ct via tc_skb_ext and tc_skb_cb to the openvswitch module, so
the packet flow key NAT flags will be correctly set.

Check if the destination register already contains the data that this
bitwise expression performs. This allows to skip this redundant
operation.
If the destination contains a different bitwise operation, cancel the
register tracking information. If the destination contains no bitwise
operation, update the register tracking information.
Update the payload and meta expression to check if this bitwise
operation has been already performed on the register. Hence, both the
payload/meta and the bitwise expressions are reduced.
There is also a special case: If source register != destination register
and source register is not updated by a previous bitwise operation, then
transfer selector from the source register to the destination register.

This patch adds new infrastructure to skip redundant selector store
operations on the same register to achieve a performance boost from
the packet path.
This is particularly noticeable in pure linear rulesets but it also
helps in rulesets which are already heaving relying in maps to avoid
ruleset linear inspection.
The idea is to keep data of the most recurrent store operations on
register to reuse them with cmp and lookup expressions.
This infrastructure allows for dynamic ruleset updates since the ruleset
blob reduction happens from the kernel.
Userspace still needs to be updated to maximize register utilization to
cooperate to improve register data reuse / reduce number of store on
register operations.

This patch adds a blob layout per chain to represent the ruleset in the
packet datapath.
size (unsigned long)
struct nft_rule_dp
struct nft_expr
...
struct nft_rule_dp
struct nft_expr
...
struct nft_rule_dp (is_last=1)
The new structure nft_rule_dp represents the rule in a more compact way
(smaller memory footprint) compared to the control-plane nft_rule
structure.
The ruleset blob is a read-only data structure. The first field contains
the blob size, then the rules containing expressions. There is a trailing
rule which is used by the tracing infrastructure which is equivalent to
the NULL rule marker in the previous representation. The blob size field
does not include the size of this trailing rule marker.
The ruleset blob is generated from the commit path.
This patch reuses the infrastructure available since 0cbc06b3faba
("netfilter: nf_tables: remove synchronize_rcu in commit phase") to
build the array of rules per chain.

nf_ct_put() results in a usesless indirection:
nf_ct_put -> nf_conntrack_put -> nf_conntrack_destroy -> rcu readlock +
indirect call of ct_hooks->destroy().
There are two _put helpers:
nf_ct_put and nf_conntrack_put. The latter is what should be used in
code that MUST NOT cause a linker dependency on the conntrack module
(e.g. calls from core network stack).
Everyone else should call nf_ct_put() instead.
A followup patch will convert a few nf_conntrack_put() calls to
nf_ct_put(), in particular from modules that already have a conntrack
dependency such as act_ct or even nf_conntrack itself.

Convert nf_conn reference counting from atomic_t to refcount_t based api.
refcount_t api provides more runtime sanity checks and will warn on
certain constructs, e.g. refcount_inc() on a zero reference count, which
usually indicates use-after-free.
For this reason template allocation is changed to init the refcount to
1, the subsequenct add operations are removed.
Likewise, init_conntrack() is changed to set the initial refcount to 1
instead refcount_inc().
This is safe because the new entry is not (yet) visible to other cpus.
