Improve retransmission backoff by only backing off when we retransmit data
packets rather than when we set the lost ack timer.
To this end:
(1) In rxrpc_resend(), use rxrpc_get_rto_backoff() when setting the
retransmission timer and only tell it that we are retransmitting if we
actually have things to retransmit.
Note that it's possible for the retransmission algorithm to race with
the processing of a received ACK, so we may see no packets needing
retransmission.
(2) In rxrpc_send_data_packet(), don't bump the backoff when setting the
ack_lost_at timer, as it may then get bumped twice.
With this, when looking at one particular packet, the retransmission
intervals were seen to be 1.5ms, 2ms, 3ms, 5ms, 9ms, 17ms, 33ms, 71ms,
136ms, 264ms, 544ms, 1.088s, 2.1s, 4.2s and 8.3s.

Add a comment into fscache_note_page_release() to explain how the
page-release optimisation logic works[1]. It's not entirely obvious as it
has nothing to do with whether or not the netfs file contains data.
FSCACHE_COOKIE_NO_DATA_TO_READ is set if we have no data in the cache yet
(ie. the backing file lookup was negative, the file is 0 length or the
cookie got invalidated). It means that we have no data in the cache, not
that the file is necessarily empty on the server.
FSCACHE_COOKIE_HAVE_DATA is set once we've stored data in the backing file.
From that point on, we have data we *could* read - however, it's covered by
pages in the netfs pagecache until at such time one of those covering pages
is released.
So if we've written data to the cache (HAVE_DATA) and there wasn't any data
in the cache when we started (NO_DATA_TO_READ), it may no longer be true
that we can skip reading from the cache.
Read skipping is done by cachefiles_prepare_read().
Note that tracking is not done on a per-page basis, but only on a per-file
basis.

Cachefiles keeps track of how much space is available on the backing
filesystem and refuses new writes permission to start if there isn't enough
(we especially don't want ENOSPC happening). It also tracks the amount of
data pending in DIO writes (cache->b_writing) and reduces the amount of
free space available by this amount before deciding if it can set up a new
write.
However, the old fscache I/O API was very much page-granularity dependent
and, as such, cachefiles's cache->bshift was meant to be a multiplier to
get from PAGE_SIZE to block size (ie. a blocksize of 512 would give a shift
of 3 for a 4KiB page) - and this was incorrectly being used to turn the
number of bytes in a DIO write into a number of blocks, leading to a
massive over estimation of the amount of data in flight.
Fix this by changing cache->bshift to be a multiplier from bytes to
blocksize and deal with quantities of blocks, not quantities of pages.
Fix also the rounding in the calculation in cachefiles_write() which needs
a "- 1" inserting.

octeontx-af2: Fixes for CN10K and CN9xxx platforms
This patchset has consolidated fixes in Octeontx2 driver
handling CN10K and CN9xxx platforms. When testing the
new CN10K hardware some issues resurfaced like accessing
wrong register for CN10K and enabling loopback on not supported
interfaces. Some fixes are needed for CN9xxx platforms as well.
Below is the description of patches
Patch 1: AF sets RX RSS action for all the VFs when a VF is
brought up. But when a PF sets RX action for its VF like Drop/Direct
to a queue in ntuple filter it is not retained because of AF fixup.
This patch skips modifying VF RX RSS action if PF has already
set its action.
Patch 2: When configuring backpressure wrong register is being read for
LBKs hence fixed it.
Patch 3: Some RVU blocks may take longer time to reset but are guaranteed
to complete the reset. Hence wait till reset is complete.
Patch 4: For enabling LMAC CN10K needs another register compared
to CN9xxx platforms. Hence changed it.
Patch 5: Adds missing barrier before submitting memory pointer
to the aura hardware.
Patch 6: Increase polling time while link credit restore and also
return proper error code when timeout occurs.
Patch 7: Internal loopback not supported on LPCS interfaces like
SGMII/QSGMII so do not enable it.
Patch 8: When there is a error in message processing, AF sets the error
response and replies back to requestor. PF forwards a invalid message to
VF back if AF reply has error in it. This way VF lacks the actual error set
by AF for its message. This is changed such that PF simply forwards the
actual reply and let VF handle the error.
Patch 9: ntuple filter with "flow-type ether proto 0x8842 vlan 0x92e"
was not working since ethertype 0x8842 is NGIO protocol. Hardware
parser explicitly parses such NGIO packets and sets the packet as
NGIO and do not set it as tagged packet. Fix this by changing parser
such that it sets the packet as both NGIO and tagged by using
separate layer types.
====================

With current KPU profile NGIO is being parsed along with CTAG as
a single layer. Because of this MCAM/ntuple rules installed with

replies after processing message requests. Currently PF

changes that such that PF simply forwards AF replies
so that VF can handle error codes.

AF modifies all the rules destined for VF to use
the action same as default RSS action. This fixup
was needed because AF only installs default rules with
RSS action. But the action in rules installed by a PF
for its VFs should not be changed by this fixup.
This is because action can be drop or direct to
queue as specified by user(ntuple filters).

If we ever see a touch report with contact count data we initialize
several variables used to read the contact count in the pre-report
phase. These variables are never reset if we process a report which
doesn't contain a contact count, however. This can cause the pre-
report function to trigger a read of arbitrary memory (e.g. NULL
if we're lucky) and potentially crash the driver.
This commit restores resetting of the variables back to default
"none" values that were used prior to the commit mentioned
below.

AES hardware may internally re-classify a contact that it thought was
intentional as a palm. Intentional contacts are reported as "down" with
the confidence bit set. When this re-classification occurs, however, the
state transitions to "up" with the confidence bit cleared. This kind of
transition appears to be legal according to Microsoft docs, but we do
not handle it correctly. Because the confidence bit is clear, we don't
call `wacom_wac_finger_slot` and update userspace. This causes hung
touches that confuse userspace and interfere with pen arbitration.
This commit adds a special case to ignore the confidence flag if a contact
is reported as removed. This ensures we do not leave a hung touch if one
of these re-classification events occured. Ideally we'd have some way to
also let userspace know that the touch has been re-classified as a palm
and needs to be canceled, but that's not possible right now :)

These two values go hand-in-hand and must be valid for the driver to
behave correctly. We are currently lazy about updating the values and
rely on the "expected" code flow to take care of making sure they're
valid at the point they're needed. The "expected" flow changed somewhat
with commit f8b6a74719 ("HID: wacom: generic: Support multiple tools
per report"), however. This led to problems with the DTH-2452 due (in
part) to *all* contacts being fully processed -- even those past the
expected contact count. Specifically, the received count gets reset to
0 once all expected fingers are processed, but not the expected count.
The rest of the contacts in the report are then *also* processed since
now the driver thinks we've only processed 0 of N expected contacts.
Later commits such as 7fb0413baa (HID: wacom: Use "Confidence" flag to
prevent reporting invalid contacts) worked around the DTH-2452 issue by
skipping the invalid contacts at the end of the report, but this is not
a complete fix. The confidence flag cannot be relied on when a contact
is removed (see the following patch), and dealing with that condition
re-introduces the DTH-2452 issue unless we also address this contact
count laziness. By resetting expected and received counts at the same
time we ensure the driver understands that there are 0 more contacts
expected in the report. Similarly, we also make sure to reset the
received count if for some reason we're out of sync in the pre-report
phase.

Intel Wired LAN Driver Updates 2022-01-20
This series contains updates to i40e driver only.
Jedrzej increases delay for EMP reset and adds checks to ensure a VF
request to change queues can be met.
Sylwester moves the placement of the Flow Director queue as to not
fragment the queue pile which would cause later re-allocation issues.
Karen prevents VF reset being invoked while another is still occurring
to avoid reading invalid data.
Joe Damato fixes some statistics fields to match the values of the
fields they are based on.

"Withdraw the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl definitions.
This is the third and final of a series of small pull requests that
perform some long overdue housecleaning of XFS ioctls. This time,
we're withdrawing all variants of the ALLOCSP and FREESP ioctls from
XFS' userspace API. This might be a little premature since we've only
just removed the functionality, but as I pointed out in the last pull
request, nobody (including fstests) noticed that it was broken for 20
years.
In response to the patch, we received a single comment from someone
who stated that they 'augment' the ioctl for their own purposes, but
otherwise acquiesced to the withdrawal. I still want to try to clobber
these old ioctl definitions in 5.17.
So remove the header definitions for these ioctls. The just-removed
implementation has allowed callers to read stale disk contents for
more than **21 years** and nobody noticed or complained, which implies
a lack of users aside from exploit programs"

Pull xfs irix ioctl housecleaning from Darrick Wong:
"Remove the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl families.
This is the second of a series of small pull requests that perform
some long overdue housecleaning of XFS ioctls. This time, we're
vacating the implementation of all variants of the ALLOCSP and FREESP
ioctls, which are holdovers from EFS in Irix, circa 1993. Roughly
equivalent functionality have been available for both ioctls since
2.6.25 (April 2008):
- XFS_IOC_FREESP ftruncates a file.
- XFS_IOC_ALLOCSP is the equivalent of fallocate.
As noted in the fix patch for CVE 2021-4155, the ALLOCSP ioctl has
been serving up stale disk blocks since 2000, and in 21 years
**nobody** noticed. On those grounds I think it's safe to vacate the
implementation.
Note that we lose the ability to preallocate and truncate relative to
the current file position, but as nobody's ever implemented that for
the VFS, I conclude that it's not in high demand.
Linux has always used fallocate as the space management system call,
whereas these Irix legacy ioctls only ever worked on XFS, and have

long overdue housecleaning of XFS ioctls. This first pull request
removes the FSSETDM ioctl, which was used to set DMAPI event
attributes on XFS files. The DMAPI support has never been merged
upstream and the implementation of FSSETDM itself was removed two
years ago, so let's withdraw it completely.
- Withdraw the ioctl definition for the FSSETDM ioctl"

mptcp: A few fixes
Patch 1 fixes a RCU locking issue when processing a netlink command that
updates endpoint flags in the in-kernel MPTCP path manager.
Patch 2 fixes a typo affecting available endpoint id tracking.
Patch 3 fixes IPv6 routing in the MPTCP self tests.

MPJ ipv6 selftests currently lack per link route to the server
net. Additionally, ipv6 subflows endpoints are created without any
interface specified. The end-result is that in ipv6 self-tests
subflows are created all on the same link, leading to expected delays
and sporadic self-tests failures.
Fix the issue by adding the missing setup bits.

In mptcp_pm_nl_rm_addr_or_subflow(), the bit of rm_list->ids[i] in the
id_avail_bitmap should be set, not rm_list->ids[1]. This patch fixed it.

The MPTCP endpoint list is under RCU protection, guarded by the
pernet spinlock. mptcp_nl_cmd_set_flags() traverses the list
without acquiring the spin-lock nor under the RCU critical section.
This change addresses the issue performing the lookup and the endpoint
update under the pernet spinlock.

When compiling the kernel with CONFIG_INET disabled, the
sk_defer_free_flush() should be defined as a nop.
This resolves the following compilation error:
ld: net/core/sock.o: in function `sk_defer_free_flush':
./include/net/tcp.h:1378: undefined reference to `__sk_defer_free_flush'

Commit bafbdd527d ("phylib: Add device reset GPIO support") added call
to phy_device_reset(phydev) after the put_device() call in phy_detach().
The comment before the put_device() call says that the phydev might go
away with put_device().
Fix potential use-after-free by calling phy_device_reset() before
put_device().
