====================
Netfilter for net
This is v3, I kept back an ipset fix and another to tigthen the xtables
interface to reject invalid combinations with the NFPROTO_ARP family.
They need a bit more discussion. I fixed the issues reported by AI on
patch 9 (add #ifdef to access ct zone, update nf_conntrack_broadcast
and patch 10 (use better Fixes: tag). Thanks!
The following patchset contains Netfilter fixes for *net*.
Note that most bugs fixed here stem from 2.6 days, the large PR is not
due to an increase in regressions.
1) Fix incorrect reject of set updates with nf_tables pipapo set
avx2 backend. This comes with a regression test in patch 2.
From Florian Westphal.
2) nfnetlink_log needs to zero padding to prevent infoleak to userspace,
from Weiming Shi.
3) xtables ip6t_rt module never validated that addrnr length is within the
allowed array boundary. Reject bogus values. From Ren Wei.
4) Fix high memory usage in rbtree set backend that was unwanted side-effect
of the recently added binary search blob. From Pablo Neira Ayuso.
5) Patches 5 to 10, also from Pablo, address long-standing RCU safety bugs
in conntracks handling of expectations: We can never safely defer
a conntrack extension area without holding a reference. Yet expectation
handling does so in multiple places. Fix this by avoiding the need to
look into the master conntrack to begin with and by extending locked
sections in a few places.
11) Fix use of uninitialized rtp_addr in the sip conntrack helper,
also from Weiming Shi.
12) Add stricter netlink policy checks in ctnetlink, from David Carlier.
This avoids undefined behaviour when userspace provides huge wscale
value.

Introduce the FOR_EACH_NS_TYPE(X) macro as the single source of truth
for the set of (struct type, CLONE_NEW* flag) pairs that define Linux

Currently, the list of CLONE_NEW* flags is duplicated inline in
multiple call sites and would need another copy in each new consumer.
This makes it easy to miss one when a new namespace type is added.
Derive two things from the X-macro:
- CLONE_NS_ALL: Bitmask of all known CLONE_NEW* flags, usable as a
validity mask or iteration bound.
- ns_common_type(): Rewritten to use the X-macro via a leading-comma
_Generic pattern, so the struct-to-flag mapping stays in sync with the
flag set automatically.
Replace the inline flag enumerations in copy_namespaces(),
unshare_nsproxy_namespaces(), check_setns_flags(), and
ksys_unshare() with CLONE_NS_ALL.
When a new namespace type is added, only FOR_EACH_NS_TYPE needs to
be updated; CLONE_NS_ALL, ns_common_type(), and all the call sites
pick up the change automatically.

fs: Remove inode lock from __generic_file_fsync()
Inode lock in __generic_file_fsync() protects sync_mapping_buffers() and
sync_inode_metadata() calls. Neither sync_mapping_buffers() nor
sync_inode_metadata() themselves need the protection by inode_lock and
both metadata buffer head writeback and inode writeback can happen
without inode lock (either in case of background writeback or sync(2)
calls). The only protection inode_lock can possibly provide is that
write(2) or other inode modifying calls cannot happen in the middle of
bh+inode writeout and thus result in writeout of inconsistent metadata.
However if writes and fsyncs race, background writeback can submit
inconsistent metadata just after fsync completed even with inode_lock
protecting fsync so this seems moot as well. So let's remove the
apparently pointless inode_lock protection.

ASoC: fsl: mpc5200_dma: Convert to devm_ioremap()

iounmap() calls from the error path in mpc5200_audio_dma_create() and

Since devm_ioremap() failure already returns directly and no other

return -ENOMEM directly instead of jumping to the now-removed out_unmap
label.
The kernel test robot reported that on hexagon with clang, several test
functions in fat_test.c exceed the 1280-byte stack frame limit.
The root cause is the compound literal assignment in
fat_test_set_time_offset():
*sbi = (struct msdos_sb_info){};
struct msdos_sb_info contains two hash tables of 256 hlist_head entries
(FAT_HASH_SIZE), making it several kilobytes. The compound literal
creates a temporary on the stack, and when clang inlines
fat_test_set_time_offset() into each test function, the large temporary
inflates every caller's stack frame beyond the limit.
Replace the compound literal with memset() which zeroes the struct
in-place without a stack temporary.

The current settings for the "image vertical start" register appear to be
incorrect. While this only results in an incorrect start line for native
modes, this faulty setting causes actual problems in binning mode. At least
on an i.MX8MP test system, only corrupted frames could be received.
To correct this, the recommended settings from the reference register sets
are used for all modes. Since this shifts the start by one line, the Bayer
pattern also changes, which has also been corrected.

source of failure.
However this makes encoding the description in the tracepoints sort of a
waste of memory. David Laight also points out that file_path doesn't
zero the whole buffer which causes exposure of stale trace bytes, and
Steven Rostedt wonders why we're not using a dynamic array for the file
path.
I don't think this is worth fixing, so let's just rip it out.
