The config done bits of VP0, VP1, VP2 on RK3568 stands on
the first three bits on REG_CFG_DONE register without mask bit.
If two or three config done events happens one after
another in a very shot time, the flowing config done
write may override the previous config done bit before
it take effect:
1: config done 0x8001 for VP0
2: config done 0x8002 for VP1
0x8002 may override 0x8001 before it take effect.
So we do a read | write here.

commit f6351c3f1c upstream.
The old way of changing the conntrack hashsize runtime was through changing
the module param via file /sys/module/nf_conntrack/parameters/hashsize. This
was extended to sysctl change in commit 3183ab8997 ("netfilter: conntrack:
allow increasing bucket size via sysctl too").
The commit introduced second "user" variable nf_conntrack_htable_size_user
which shadow actual variable nf_conntrack_htable_size. When hashsize is
changed via module param this "user" variable isn't updated. This results in
sysctl net/netfilter/nf_conntrack_buckets shows the wrong value when users
update via the old way.
This patch fix the issue by always updating "user" variable when reading the
proc file. This will take care of changes to the actual variable without
sysctl need to be aware.

commit e7c22eeaff upstream.
As snd_ff.rx_bytes[] is unsigned int, and NSEC_PER_SEC is 1000000000L,
the second multiplication in
ff->rx_bytes[port] * 8 * NSEC_PER_SEC / 31250
always overflows on 32-bit platforms, truncating the result. Fix this
by precalculating "NSEC_PER_SEC / 31250", which is an integer constant.
Note that this assumes ff->rx_bytes[port] <= 16777.

There wasn't ever a real need to log an error in the kernel log for
ioctls issued with insufficient permissions. Simply return an error
and if an admin/user is sufficiently motivated they can enable DM's

disallowed.

commit 86b53fbf08 upstream.
A return value of 0 means success. This is documented in lib/kstrtox.c.
This was found by trying to mount an NFS share from a link-local IPv6
address with the interface specified by its index:
mount("[fe80::1%1]:/srv/nfs", "/mnt", "nfs", 0, "nolock,addr=fe80::1%1")
Before this commit this failed with EINVAL and also caused the following
message in dmesg:
[...] NFS: bad IP address specified: addr=fe80::1%1
The syscall using the same address based on the interface name instead
of its index succeeds.
Credits for this patch go to my colleague Christian Speich, who traced
the origin of this bug to this line of code.

commit 8ff60eb052 upstream.
acquire_slab() fails if there is contention on the freelist of the page
(probably because some other CPU is concurrently freeing an object from
the page). In that case, it might make sense to look for a different page
(since there might be more remote frees to the page from other CPUs, and
we don't want contention on struct page).
However, the current code accidentally stops looking at the partial list
completely in that case. Especially on kernels without CONFIG_NUMA set,
this means that get_partial() fails and new_slab_objects() falls back to
new_slab(), allocating new pages. This could lead to an unnecessary
increase in memory fragmentation.
