When an ULP-enabled socket enters the LISTEN status, the listener ULP data
pointer is copied inside the child/accepted sockets by sk_clone_lock().

The relevant ULP can take care of de-duplicating the context pointer via
the clone() operation, but only MPTCP and SMC implement such op.

Other ULPs may end-up with a double-free at socket disposal time.

We can't simply clear the ULP data at clone time, as TLS replaces the
socket ops with custom ones assuming a valid TLS ULP context is
available.

Instead completely prevent clone-less ULP sockets from entering the
LISTEN status.

By default, qed_mcp_cmd_and_union() delays 10us at a time in a loop
that can run 500K times, so calls to qed_mcp_nvm_rd_cmd()
may block the current thread for over 5s.
We observed thread scheduling delays over 700ms in production,
with stacktraces pointing to this code as the culprit.

qed_mcp_trace_dump() is called from ethtool, so sleeping is permitted.
It already can sleep in qed_mcp_halt(), which calls qed_mcp_cmd().
Add a "can sleep" parameter to qed_find_nvram_image() and
qed_nvram_read() so they can sleep during qed_mcp_trace_dump().
qed_mcp_trace_get_meta_info() and qed_mcp_trace_read_meta(),
called only by qed_mcp_trace_dump(), allow these functions to sleep.
I can't tell if the other caller (qed_grc_dump_mcp_hw_dump()) can sleep,
so keep b_can_sleep set to false when it calls these functions.

showing a thread that has not scheduled despite long needing resched:

With below two cases, it will cause NULL pointer dereference when
accessing SM_I(sbi)->fcc_info in f2fs_issue_flush().

a) If kthread_run() fails in f2fs_create_flush_cmd_control(), it will
release SM_I(sbi)->fcc_info,

- mount -o noflush_merge /dev/vda /mnt/f2fs
- mount -o remount,flush_merge /dev/vda /mnt/f2fs  -- kthread_run() fails
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync

b) we will never allocate memory for SM_I(sbi)->fcc_info w/ below
testcase,

- mount -o ro /dev/vda /mnt/f2fs
- mount -o rw,remount /dev/vda /mnt/f2fs
- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync

In order to fix this issue, let change as below:
- fix error path handling in f2fs_create_flush_cmd_control().
- allocate SM_I(sbi)->fcc_info even if readonly is on.

Variables off and len typed as uint32 in rndis_query function
are controlled by incoming RNDIS response message thus their
value may be manipulated. Setting off to a unexpectetly large
value will cause the sum with len and 8 to overflow and pass

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Use signed integer in ipv6_skip_exthdr() called from nf_confirm().
   Reported by static analysis tooling, patch from Florian Westphal.

2) Missing set type checks in nf_tables: Validate that set declaration
   matches the an existing set type, otherwise bail out with EEXIST.
   Currently, nf_tables silently accepts the re-declaration with a
   different type but it bails out later with EINVAL when the user adds
   entries to the set. This fix is relatively large because it requires
   two preparation patches that are included in this batch.

3) Do not ignore updates of timeout and gc_interval parameters in
   existing sets.

4) Fix a hang when 0/0 subnets is added to a hash:net,port,net type of
   ipset. Except hash:net,port,net and hash:net,iface, the set types don't
   support 0/0 and the auxiliary functions rely on this fact. So 0/0 needs
   a special handling in hash:net,port,net which was missing (hash:net,iface
   was not affected by this bug), from Jozsef Kadlecsik.

5) When adding/deleting large number of elements in one step in ipset,
   it can take a reasonable amount of time and can result in soft lockup
   errors. This patch is a complete rework of the previous version in order
   to use a smaller internal batch limit and at the same time removing
   the external hard limit to add arbitrary number of elements in one step.
   Also from Jozsef Kadlecsik.

Except for patch #1, which fixes a bug introduced in the previous net-next
development cycle, anything else has been broken for several releases.

syzbot is reporting hung task at do_user_addr_fault() [1], for there is
a silent deadlock between PG_locked bit and ni_lock lock.

Since filemap_update_page() calls filemap_read_folio() after calling
folio_trylock() which will set PG_locked bit, ntfs_truncate() must not
call truncate_setsize() which will wait for PG_locked bit to be cleared
when holding ni_lock lock.

If v4 READDIR operation hits a mountpoint and gets back an error,
then it will include that entry in the reply and set RDATTR_ERROR for it
to the error.

That's fine for "normal" exported filesystems, but on the v4root, we
need to be more careful to only expose the existence of dentries that
lead to exports.

If the mountd upcall times out while checking to see whether a
mountpoint on the v4root is exported, then we have no recourse other
than to fail the whole operation.

Commit 62d89a7d ("video: fbdev: matroxfb: set maxvram of vbG200eW to
the same as vbG200 to avoid black screen") accidently decreases the
maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB
by missing one zero. This caused the driver initialization to fail with
the messages below, as the minimum required VRAM size is 2 MB:

     [    9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected
     [    9.444502] matroxfb: cannot determine memory size
     [    9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1

So, add the missing 0 to make it the intended 16 MB. Successfully tested on
the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is
gone.

While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned
properly. The value could probably also be increased from 8 MB to 16 MB, as
the G200 uses the same values, but I have not checked any datasheet.

Note, matroxfb is obsolete and superseded by the maintained DRM driver
mga200, which is used by default on most systems where both drivers are
available. Therefore, on most systems it was only a cosmetic issue.

When adding/deleting large number of elements in one step in ipset, it can
take a reasonable amount of time and can result in soft lockup errors. The
patch 5f7b51bf ("netfilter: ipset: Limit the maximal range of
consecutive elements to add/delete") tried to fix it by limiting the max
elements to process at all. However it was not enough, it is still possible
that we get hung tasks. Lowering the limit is not reasonable, so the
approach in this patch is as follows: rely on the method used at resizing
sets and save the state when we reach a smaller internal batch limit,
unlock/lock and proceed from the saved state. Thus we can avoid long
continuous tasks and at the same time removed the limit to add/delete large
number of elements in one step.

The nfnl mutex is held during the whole operation which prevents one to
issue other ipset commands in parallel.
