95b97fe010 arm64: dts: qcom: monaco-evk-camera: Add DT overlay
Monaco EVK board does not include a camera sensor in its default hardware
configuration. Introducing a device tree overlay to support optional
integration of the IMX577 sensor via CSIPHY1.

Camera reset is handled through an I2C expander, and power is enabled
via TLMM GPIO74.

An example media-ctl pipeline for the imx577 is:

media-ctl --reset
media-ctl -V '"imx577 3-001a":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy1":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy1":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'

Traditionally, firmware loading for Serial Engines (SE) in the QUP hardware
of Qualcomm SoCs has been managed by TrustZone (TZ). While this approach
ensures secure SE assignment and access control, it limits flexibility for
developers who need to enable various protocols on different SEs.

Add the firmware-name property to QUPv3 nodes in the device tree to enable
firmware loading from the Linux environment. Handle SE assignments and
access control permissions directly within Linux, removing the dependency
on TrustZone.

Merge tag 'nf-26-03-26' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf

Pablo Neira Ayuso says:

====================
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.

nsproxy: Add FOR_EACH_NS_TYPE() X-macro and CLONE_NS_ALL
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
namespace types.

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.

netfs: Fix the handling of stream->front by removing it
The netfs_io_stream::front member is meant to point to the subrequest
currently being collected on a stream, but it isn't actually used this way
by direct write (which mostly ignores it).  However, there's a tracepoint
which looks at it.  Further, stream->front is actually redundant with
stream->subrequests.next.

Fix the potential problem in the direct code by just removing the member
and using stream->subrequests.next instead, thereby also simplifying the
code.

deec4f7b41 Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue
Tony Nguyen says:

====================
For ice:
Michal corrects call to alloc_etherdev_mqs() to provide maximum number
of queues supported rather than currently allocated number of queues.

Petr Oros fixes issues related to some ethtool operations in switchdev
mode.

For iavf:
Kohei Enju corrects number of reported queues for ethtool statistics to
absolute max as using current number could race and cause out-of-bounds
issues.

For idpf:
Josh NULLs cdev_info pointer after freeing to prevent possible subsequent
improper access. He also defers setting of refillqs value until after
allocation to prevent possible NULL pointer dereference.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  idpf: only assign num refillqs if allocation was successful
  idpf: clear stale cdev_info ptr
  iavf: fix out-of-bounds writes in iavf_get_ethtool_stats()
  ice: use ice_update_eth_stats() for representor stats
  ice: fix inverted ready check for VF representors

Merge patch series "fs: Move metadata bh tracking from address_space"
Jan Kara <jack@suse.cz> says:

This patch series cleans up the mess that has accumulated over the years in
metadata buffer_head tracking for inodes, moves the tracking into dedicated
structure in filesystem-private part of the inode (so that we don't use
private_list, private_data, and private_lock in struct address_space), and also
moves couple other users of private_data and private_list so these are removed
from struct address_space saving 3 longs in struct inode for 99% of inodes.  I
would like to get rid of private_lock in struct address_space as well however
the locking changes for buffer_heads are non-trivial there and the patch series
is long enough as is. So let's leave that for another time.

fs: Move metadata bhs tracking to a separate struct
Instead of tracking metadata bhs for a mapping using i_private_list and
i_private_lock create a dedicated mapping_metadata_bhs struct for it.
So far this struct is embedded in address_space but that will be
switched for per-fs private inode parts later in the series. This also
changes the locking from bdev mapping's i_private_lock to a new lock
embedded in mapping_metadata_bhs to untangle the i_private_lock locking
for maintaining lists of metadata bhs and the locking for looking up /
reclaiming bdev's buffer heads. The locking in remove_assoc_map() gets
more complex due to this but overall this looks like a reasonable
tradeoff.

The function only waits for already locked buffers in the list of

IO on buffers so this isn't adding anything useful. Comment in front of
fsync_buffers_list() mentions concerns about buffers being moved out
from tmp list back to mappings i_private_list but these days
mark_buffer_dirty_inode() doesn't touch inodes with b_assoc_map set so
that cannot happen. Just delete the stale code.
