Commit 01239d77b9dd ("xfs: fix a null pointer dereference in
xfs_bmap_extents_to_btree") attempted to fix a null pointer
dreference when a fuzzing corruption of some kind was found.
This fix was flawed, resulting in assert failures like:
XFS: Assertion failed: ifp->if_broot == NULL, file: fs/xfs/libxfs/xfs_bmap.c, line: 715
.....
Call Trace:
xfs_bmap_extents_to_btree+0x6b9/0x7b0
__xfs_bunmapi+0xae7/0xf00
? xfs_log_reserve+0x1c8/0x290

vfs_dedupe_file_range_one+0xd7/0xe0
vfs_dedupe_file_range+0x15b/0x1a0
do_vfs_ioctl+0x267/0x6c0
The problem is that the error handling code now asserts that the
inode fork is not in btree format before the error handling code
undoes the modifications that put the fork back in extent format.
Fix this by moving the assert back to after the xfs_iroot_realloc()
call that returns the fork to extent format, and clean up the jump
labels to be meaningful.
Also, returning ENOSPC when xfs_btree_get_bufl() fails to
instantiate the buffer that was allocated (the actual fix in the
commit mentioned above) is incorrect. This is a fatal error - only
an invalid block address or a filesystem shutdown can result in
failing to get a buffer here.
Hence change this to EFSCORRUPTED so that the higher layer knows
this was a corruption related failure and should not treat it as an
ENOSPC error. This should result in a shutdown (via cancelling a
dirty transaction) which is necessary as we do not attempt to clean
up the (invalid) block that we have already allocated.

As reported by nixiaoming, with some minor clarifications:
1) memory leak in ramoops_register_dummy():
dummy_data = kzalloc(sizeof(*dummy_data), GFP_KERNEL);
but no kfree() if platform_device_register_data() fails.
2) memory leak in ramoops_init():
Missing platform_device_unregister(dummy) and kfree(dummy_data)
if platform_driver_register(&ramoops_driver) fails.
I've clarified the purpose of ramoops_register_dummy(), and added a
common cleanup routine for all three failure paths to call.

In regular NIC transmission flow, driver always configures MAC using
Tx queue zero descriptor as a part of MAC learning flow.
But with multi Tx queue supported NIC, regular transmission can occur on
any non-zero Tx queue and from that context it uses
Tx queue zero descriptor to configure MAC, at the same time TX queue
zero could be used by another CPU for regular transmission
which could lead to Tx queue zero descriptor corruption and cause FW
abort.
This patch fixes this in such a way that driver always configures
learned MAC address from the same Tx queue which is used for
regular transmission.

We see the following scenario:
1) Link endpoint B on node 1 discovers that its peer endpoint is gone.
Since there is a second working link, failover procedure is started.
2) Link endpoint A on node 1 sends a FAILOVER message to peer endpoint
A on node 2. The node item 1->2 goes to state FAILINGOVER.
3) Linke endpoint A/2 receives the failover, and is supposed to take
down its parallell link endpoint B/2, while producing a FAILOVER
message to send back to A/1.
4) However, B/2 has already been deleted, so no FAILOVER message can
created.
5) Node 1->2 remains in state FAILINGOVER forever, refusing to receive
any messages that can bring B/1 up again. We are left with a non-
redundant link between node 1 and 2.
We fix this with letting endpoint A/2 build a dummy FAILOVER message
to send to back to A/1, so that the situation can be resolved.

Structure 'tls_rec' contains sg_aead_in and sg_aead_out which point
to a aad_space and then chain scatterlists sg_plaintext_data,
sg_encrypted_data respectively. Rather than using chained scatterlists
for plaintext and encrypted data in aead_req, it is efficient to store
aad_space in sg_encrypted_data and sg_plaintext_data itself in the
first index and get rid of sg_aead_in, sg_aead_in and further chaining.
This requires increasing size of sg_encrypted_data & sg_plaintext_data
arrarys by 1 to accommodate entry for aad_space. The code which uses
sg_encrypted_data and sg_plaintext_data has been modified to skip first
index as it points to aad_space.

====================
rxrpc: Fixes
Here are some miscellaneous fixes for AF_RXRPC:
(1) Remove a duplicate variable initialisation.
(2) Fix one of the checks made when we decide to set up a new incoming
service call in which a flag is being checked in the wrong field of
the packet header. This check is abstracted out into helper
functions.
(3) Fix RTT gathering. The code has been trying to make use of socket
timestamps, but wasn't actually enabling them. The code has also been
recording a transmit time for the outgoing packet for which we're
going to measure the RTT after sending the message - but we can get
the incoming packet before we get to that and record a negative RTT.
(4) Fix the emission of BUSY packets (we are emitting ABORTs instead).
(5) Improve error checking on incoming packets.
(6) Try to fix a bug in new service call handling whereby a BUG we should
never be able to reach somehow got triggered. Do this by moving much
of the checking as early as possible and not repeating it later
(depends on (5) above).
(7) Fix the sockopts set on a UDP6 socket to include the ones set on a
UDP4 socket so that we receive UDP4 errors and packet-too-large
notifications too.

thereby cutting short any transmissions that would otherwise occur in
the window.

tipc: make connection setup more robust
In this series we make a few improvements to the connection setup and
probing mechanism, culminating in the last commit where we make it

it encounters receive buffer overflow at the listener socket.
