====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Missing sanitization of rateest userspace string, bug has been
triggered by syzbot, patch from Florian Westphal.
2) Report EOPNOTSUPP on missing set features in nft_dynset, otherwise
error reporting to userspace via EINVAL is misleading since this is
reserved for malformed netlink requests.
3) New binaries with old kernels might silently accept several set
element expressions. New binaries set on the NFT_SET_EXPR and
NFT_DYNSET_F_EXPR flags to request for several expressions per
element, hence old kernels which do not support for this bail out
with EOPNOTSUPP.

====================
net: dsa: lantiq_gswip: two fixes for -net/-stable
While testing the lantiq_gswip driver in OpenWrt at least one board had
a non-working Ethernet port connected to an internal 100Mbit/s PHY22F
GPHY. The problem which could be observed:
- the PHY would detect the link just fine
- ethtool stats would see the TX counter rise
- the RX counter in ethtool was stuck at zero
It turns out that two independent patches are needed to fix this:
- first we need to enable the MII data lines also for internal PHYs
- second we need to program the GSWIP_MII_CFG registers for all ports
except the CPU port
These two patches have also been tested by back-porting them on top of
Linux 5.4.86 in OpenWrt.
Special thanks to Hauke for debugging and brainstorming this on IRC
with me!

There is one GSWIP_MII_CFG register for each switch-port except the CPU
port. The register offset for the first port is 0x0, 0x02 for the
second, 0x04 for the third and so on.
Update the driver to not only restrict the GSWIP_MII_CFG registers to
ports 0, 1 and 5. Handle ports 0..5 instead but skip the CPU port. This
means we are not overwriting the configuration for the third port (port
two since we start counting from zero) with the settings for the sixth
port (with number five) anymore.
The GSWIP_MII_PCDU(p) registers are not updated because there's really
only three (one for each of the following ports: 0, 1, 5).

Enable GSWIP_MII_CFG_EN also for internal PHYs to make traffic flow.
Without this the PHY link is detected properly and ethtool statistics
for TX are increasing but there's no RX traffic coming in.

In lapb_device_event, lapb_devtostruct is called to get a reference to
an object of "struct lapb_cb". lapb_devtostruct increases the refcount
of the object and returns a pointer to it. However, we didn't decrease
the refcount after we finished using the pointer. This patch fixes this
problem.

The test was setting the headroom size of the wrong port. This was not
visible because of a firmware bug that canceled this bug.
Set the headroom size of the correct port, so that the test will pass
with both old and new firmware versions.

A new flag MACB_CAPS_CLK_HW_CHG was added and all callers of
macb_set_tx_clk were gated on the presence of this flag.
- if (!clk)
+ if (!bp->tx_clk || !(bp->caps & MACB_CAPS_CLK_HW_CHG))
However the flag was not added to anything other than the new
sama7g5_gem, turning that function call into a no op for all other
systems. This breaks the networking on Zynq.
The commit message adding this states: a new capability so that
macb_set_tx_clock() to not be called for IPs having this
capability
This strongly implies that present of the flag was intended to skip
the function not absence of the flag. Update the if statement to
this effect, which repairs the existing users.

Before commit 889b8f964f2f ("packet: Kill CONFIG_PACKET_MMAP.") there
used to be a CONFIG_PACKET_MMAP config symbol that depended on
CONFIG_PACKET. The text still implies that PACKET_MMAP can be disabled.
Remove that from the text, as well as reference to old kernel versions.
Also, drop reference to broken link to information for pre 2.6.5
kernels.
Make a slight working improvement (s/In/On/) while at it.

Currently the vhost_zerocopy_callback() maybe be called to decrease
the refcount when sendmsg fails in tun. The error handling in vhost
handle_tx_zerocopy() will try to decrease the same refcount again.
This is wrong. To fix this issue, we only call vhost_net_ubuf_put()
when vq->heads[nvq->desc].len == VHOST_DMA_IN_PROGRESS.

In the bareudp6_xmit_skb(), it calculates min_headroom.
At that point, it uses struct iphdr, but it's not correct.
So panic could occur.
The struct ipv6hdr should be used.

ip netns add A
ip netns add B
ip link add veth0 netns A type veth peer name veth1 netns B
ip netns exec A ip link set veth0 up
ip netns exec A ip a a 2001:db8:0::1/64 dev veth0
ip netns exec B ip link set veth1 up
ip netns exec B ip a a 2001:db8:0::2/64 dev veth1

Pull RCU fix from Paul McKenney:
"This is a fix for a regression in the v5.10 merge window, but it was
reported quite late in the v5.10 process, plus generating and testing
the fix took some time.
The regression is due to commit 36dadef23fcc ("kprobes: Init kprobes
in early_initcall") which on powerpc can use RCU Tasks before
initialization, resulting in boot failures.
The fix is straightforward, simply moving initialization of RCU Tasks
before the early_initcall()s. The fix has been exposed to -next and
kbuild test robot testing, and has been tested by the PowerPC guys"

kunit_tool relies on the UML console outputting printk() output to the
tty in order to get results. Since the default console driver could
change, pass 'console=tty' to the kernel.
This is triggered by a change[1] to use ttynull as a fallback console
driver which -- by chance or by design -- seems to have changed the
default console output on UML, breaking kunit_tool. While this may be
fixed, we should be less fragile to such changes in the default.

Clevo W35xSS_370SS with VIA codec has had the runtime PM problem that
looses the power state of some nodes after the runtime resume. This
was worked around by disabling the default runtime PM via a denylist
entry. Since 5.10.x made the runtime PM applied (casually) even
though it's disabled in the denylist, this problem was revisited. The
result was that disabling power_save_node feature suffices for the
runtime PM problem.
This patch implements the disablement of power_save_node feature in
VIA codec for the device. It also drops the former denylist entry,
too, as the runtime PM should work in the codec side properly now.

The number of dirent records used by an AFS directory entry should be
calculated using the assumption that there is a 16-byte name field in the
first block, rather than a 20-byte name field (which is actually the case).
This miscalculation is historic and effectively standard, so we have to use
it.
The calculation we need to use is:
1 + (((strlen(name) + 1) + 15) >> 5)
where we are adding one to the strlen() result to account for the NUL
termination.
Fix this by the following means:
(1) Create an inline function to do the calculation for a given name
length.
(2) Use the function to calculate the number of records used for a dirent
in afs_dir_iterate_block().
Use this to move the over-end check out of the loop since it only
needs to be done once.
Further use this to only go through the loop for the 2nd+ records
composing an entry. The only test there now is for if the record is
allocated - and we already checked the first block at the top of the
outer loop.
(3) Add a max name length check in afs_dir_iterate_block().
(4) Make afs_edit_dir_add() and afs_edit_dir_remove() use the function
from (1) to calculate the number of blocks rather than doing it
incorrectly themselves.

AFS has a structured layout in its directory contents (AFS dirs are
downloaded as files and parsed locally by the client for lookup/readdir).
The slots in the directory are defined by union afs_xdr_dirent. This,
however, only directly allows a name of a length that will fit into that
union. To support a longer name, the next 1-8 contiguous entries are
annexed to the first one and the name flows across these.
afs_dir_iterate_block() uses strnlen(), limited to the space to the end of
the page, to find out how long the name is. This worked fine until
6a39e62abbaf. With that commit, the compiler determines the size of the
array and asserts that the string fits inside that array. This is a
problem for AFS because we *expect* it to overflow one or more arrays.
A similar problem also occurs in afs_dir_scan_block() when a directory file
is being locally edited to avoid the need to redownload it. There strlen()
was being used safely because each page has the last byte set to 0 when the
file is downloaded and validated (in afs_dir_check_page()).
Fix this by changing the afs_xdr_dirent union name field to an
indeterminate-length array and dropping the overflow field.
(Note that whilst looking at this, I realised that the calculation of the
number of slots a dirent used is non-standard and not quite right, but I'll
address that in a separate patch.)
The issue can be triggered by something like:
touch /afs/example.com/thisisaveryveryverylongname
and it generates a report that looks like:
detected buffer overflow in strnlen

Systems configured with CONFIG_ZONE_DMA32, CONFIG_ZONE_NORMAL and
!CONFIG_ZONE_DMA will fail to properly setup ARCH_LOW_ADDRESS_LIMIT. The
limit will default to ~0ULL, effectively spanning the whole memory,
which is too high for a configuration that expects low memory to be
capped at 4GB.
Fix ARCH_LOW_ADDRESS_LIMIT by falling back to arm64_dma32_phys_limit
when arm64_dma_phys_limit isn't set. arm64_dma32_phys_limit will honour
CONFIG_ZONE_DMA32, or span the entire memory when not enabled.

Summary: 0/0 PASSED, 0 SKIPPED, 2 FAILED
When doing merge conflict resolution, Commit 4bfc4714849d missed to
save curr_task to seq_file private data. The task pointer in seq_file
private data is passed to bpf program. This caused NULL-pointer task
passed to bpf program which will immediately return upon checking
whether task pointer is NULL.
This patch added back the assignment of curr_task to seq_file private
data and fixed the issue.

Pavel reports that commit 17858b140bf4 ("crypto: ecdh - avoid unaligned
accesses in ecdh_set_secret()") fixes one problem but introduces another:
the unconditional memcpy() introduced by that commit may overflow the
target buffer if the source data is invalid, which could be the result of
intentional tampering.
So check params.key_size explicitly against the size of the target buffer
before validating the key further.

Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block
size multiples") refactored the chacha block handling in the glue code in
a way that may result in the counter increment to be omitted when calling
chacha_block_xor_neon() to process a full block. This violates the skcipher
API, which requires that the output IV is suitable for handling more input
as long as the preceding input has been presented in round multiples of the
block size. Also, the same code is exposed via the chacha library interface
whose callers may actually rely on this increment to occur even for final
blocks that are smaller than the chacha block size.
So increment the counter after calling chacha_block_xor_neon().

Pull power management fixes from Rafael Wysocki:
"These fix a crash in intel_pstate during resume from suspend-to-RAM
that may occur after recent changes and two resource leaks in error
paths in the operating performance points (OPP) framework, add a new
C-states table to intel_idle and update the cpuidle MAINTAINERS entry
to cover the governors too.
Specifics:
- Fix recently introduced crash in the intel_pstate driver that
occurs if scale-invariance is disabled during resume from
suspend-to-RAM due to inconsistent changes of APERF or MPERF MSR
values made by the platform firmware (Rafael Wysocki).
- Fix a memory leak and add a missing clk_put() in error paths in the
OPP framework (Quanyang Wang, Viresh Kumar).
- Add new C-states table for SnowRidge processors to the intel_idle
driver (Artem Bityutskiy).
- Update the MAINTAINERS entry for cpuidle to make it clear that the
governors are covered by it too (Lukas Bulwahn)"

Pull SCSI fixes from James Bottomley:
"This is a load of driver fixes (12 ufs, 1 mpt3sas, 1 cxgbi).
The big core two fixes are for power management ("block: Do not accept
any requests while suspended" and "block: Fix a race in the runtime
power management code") which finally sorts out the resume problems
we've occasionally been having.
To make the resume fix, there are seven necessary precursors which
effectively renames REQ_PREEMPT to REQ_PM, so every "special" request
in block is automatically a power management exempt one.
All of the non-PM preempt cases are removed except for the one in the
SCSI Parallel Interface (spi) domain validation which is a genuine
case where we have to run requests at high priority to validate the
bus so this becomes an autopm get/put protected request"
