The "pending connections" feature was originally introduced with commit
4c67bc74f016 ("[Bluetooth] Support concurrent connect requests") and
6bd57416127e ("[Bluetooth] Handling pending connect attempts after
inquiry") to handle controllers supporting only a single connection request
at a time. Later things were extended to also cancel ongoing inquiries on
connect() with commit 89e65975fea5 ("Bluetooth: Cancel Inquiry before
Create Connection").
With commit a9de9248064b ("[Bluetooth] Switch from OGF+OCF to using only
opcodes"), hci_conn_check_pending() was introduced as a helper to
consolidate a few places where we check for pending connections (indicated
by the BT_CONNECT2 flag) and then try to connect.
This refactoring commit also snuck in two more calls to
hci_conn_check_pending():
- One is in the failure callback of hci_cs_inquiry(), this one probably
makes sense: If we send an "HCI Inquiry" command and then immediately
after a "Create Connection" command, the "Create Connection" command might
fail before the "HCI Inquiry" command, and then we want to retry the
"Create Connection" on failure of the "HCI Inquiry".
- The other added call to hci_conn_check_pending() is in the event handler
for the "Remote Name" event, this seems unrelated and is possibly a
copy-paste error, so remove that one.

On a lot of platforms (at least the MS Surface devices, M1 macbooks, and
a few ThinkPads) firmware doesn't do its job when rfkilling a device
and the bluetooth adapter is not actually shut down properly on rfkill.
This leads to connected devices remaining in connected state and the
bluetooth connection eventually timing out after rfkilling an adapter.
Use the rfkill hook in the HCI driver to go through the full power-off
sequence (including stopping scans and disconnecting devices) before
rfkilling it, just like MGMT_OP_SET_POWERED would do.
In case anything during the larger power-off sequence fails, make sure
the device is still closed and the rfkill ends up being effective in
the end.

Queuing of power_off work was introduced in these functions with commits
8b064a3ad377 ("Bluetooth: Clean up HCI state when doing power off") and
c9910d0fb4fc ("Bluetooth: Fix disconnecting connections in non-connected
states") in an effort to clean up state and do things like disconnecting
devices before actually powering off the device.
After that, commit a3172b7eb4a2 ("Bluetooth: Add timer to force power off")
introduced a timeout to ensure that the device actually got powered off,
even if some of the cleanup work would never complete.
This code later got refactored with commit cf75ad8b41d2 ("Bluetooth:
hci_sync: Convert MGMT_SET_POWERED"), which made powering off the device
synchronous and removed the need for initiating the power_off work from
other places. The timeout mentioned above got removed too, because we now
also made use of the command timeout during power on/off.
These days the power_off work still exists, but it only seems to only be
used for HCI_AUTO_OFF functionality, which is why we never noticed
those two leftover places where we queue power_off work. So let's remove
that code.

This fixes the tx timeout issue seen while running a stress test on
btnxpuart for couple of hours, such that the interval between two HCI
commands coincide with the power save timeout value of 2 seconds.
Test procedure using bash script:
<load btnxpuart.ko>
hciconfig hci0 up
//Enable Power Save feature
hcitool -i hci0 cmd 3f 23 02 00 00
while (true)
do
hciconfig hci0 leadv
sleep 2
hciconfig hci0 noleadv
sleep 2
done
Error log, after adding few more debug prints:
Bluetooth: btnxpuart_queue_skb(): 01 0A 20 01 00
Bluetooth: hci0: Set UART break: on, status=0
Bluetooth: hci0: btnxpuart_tx_wakeup() tx_work scheduled
Bluetooth: hci0: btnxpuart_tx_work() dequeue: 01 0A 20 01 00
Can't set advertise mode on hci0: Connection timed out (110)
Bluetooth: hci0: command 0x200a tx timeout
When the power save mechanism turns on UART break, and btnxpuart_tx_work()
is scheduled simultaneously, psdata->ps_state is read as PS_STATE_AWAKE,
which prevents the psdata->work from being scheduled, which is responsible
to turn OFF UART break.
This issue is fixed by adding a ps_lock mutex around UART break on/off as
well as around ps_state read/write.
btnxpuart_tx_wakeup() will now read updated ps_state value. If ps_state is
PS_STATE_SLEEP, it will first schedule psdata->work, and then it will
reschedule itself once UART break has been turned off and ps_state is
PS_STATE_AWAKE.
Tested above script for 50,000 iterations and TX timeout error was not
observed anymore.

Since commit 43a7206b0963 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the wpan_phy_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at boot time.

Following the addition of new GTP RSS hash options to ethtool.h, this patch
implements the corresponding RSS settings for GTP packets in the Intel ice
driver. It enables users to configure RSS for GTP-U and GTP-C traffic over IPv4
and IPv6, utilizing the newly defined hash options.
The implementation covers the handling of gtpu(4|6), gtpc(4|6), gtpc(4|6)t,
gtpu(4|6)e, gtpu(4|6)u, and gtpu(4|6)d traffic, providing enhanced load
distribution for GTP traffic across multiple processing units.

This is a patch that enables RSS functionality for GTP packets using ethtool.
A user can include TEID and make RSS work for GTP-U over IPv4 by doing the
following:`ethtool -N ens3 rx-flow-hash gtpu4 sde`
In addition to gtpu(4|6), we now support gtpc(4|6),gtpc(4|6)t,gtpu(4|6)e,
gtpu(4|6)u, and gtpu(4|6)d.
gtpc(4|6): Used for GTP-C in IPv4 and IPv6, where the GTP header format does
not include a TEID.
gtpc(4|6)t: Used for GTP-C in IPv4 and IPv6, with a GTP header format that
includes a TEID.
gtpu(4|6): Used for GTP-U in both IPv4 and IPv6 scenarios.
gtpu(4|6)e: Used for GTP-U with extended headers in both IPv4 and IPv6.
gtpu(4|6)u: Used when the PSC (PDU session container) in the GTP-U extended
header includes Uplink, applicable to both IPv4 and IPv6.
gtpu(4|6)d: Used when the PSC in the GTP-U extended header includes Downlink,
for both IPv4 and IPv6.
GTP generates a flow that includes an ID called TEID to identify the tunnel.
This tunnel is created for each UE (User Equipment).By performing RSS based on
this flow, it is possible to apply RSS for each communication unit from the UE.
Without this, RSS would only be effective within the range of IP addresses. For
instance, the PGW can only perform RSS within the IP range of the SGW.
Problematic from a load distribution perspective, especially if there's a bias
in the terminals connected to a particular base station.This case can be
solved by using this patch.

be wrong since the two drivers that actually make use of this set a

Jakub Kicinski says:
====================
tools: ynl: add --dbg-small-recv for easier kernel testing
When testing netlink dumps I usually hack some user space up
to constrain its user space buffer size (iproute2, ethtool or ynl).
Netlink will try to fill the messages up, so since these apps use
large buffers by default, the dumps are rarely fragmented.
I was hoping to figure out a way to create a selftest for dump
testing, but so far I have no idea how to do that in a useful
and generic way.
Until someone does that, make manual dump testing easier with YNL.
Create a special option for limiting the buffer size, so I don't
have to make the same edits each time, and maybe others will benefit,
too :)
Example:
$ ./cli.py [...] --dbg-small-recv >/dev/null
Recv: read 3712 bytes, 29 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
Recv: read 3968 bytes, 31 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
Recv: read 532 bytes, 5 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
nl_len = 20 (4) nl_flags = 0x2 nl_type = 3
Now let's make the DONE not fit in the last message:
$ ./cli.py [...] --dbg-small-recv 4499 >/dev/null
Recv: read 3712 bytes, 29 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
Recv: read 4480 bytes, 35 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
Recv: read 20 bytes, 1 messages
nl_len = 20 (4) nl_flags = 0x2 nl_type = 3
A real test would also have to check the messages are complete
and not duplicated. That part has to be done manually right now.
Note that the first message is always conservatively sized by the kernel.

Most "production" netlink clients use large buffers to
make dump efficient, which means that handling of dump
continuation in the kernel is not very well tested.
Add an option for debugging / testing handling of dumps.
It enables printing of extra netlink-level debug and
lowers the recv() buffer size in one go. When used
without any argument (--dbg-small-recv) it picks
a very small default (4000), explicit size can be set,
too (--dbg-small-recv 5000).
Example:
$ ./cli.py [...] --dbg-small-recv
Recv: read 3712 bytes, 29 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
Recv: read 3968 bytes, 31 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
Recv: read 532 bytes, 5 messages
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
[...]
nl_len = 128 (112) nl_flags = 0x0 nl_type = 19
nl_len = 20 (4) nl_flags = 0x2 nl_type = 3
(the [...] are edits to shorten the commit message).
Note that the first message of the dump is sized conservatively
by the kernel.

ravb: Align Rx descriptor setup and maintenance
When RZ/G2L support was added the Rx code path was split in two, one to
support R-Car and one to support RZ/G2L. One reason for this is that
R-Car uses the extended Rx descriptor format, while RZ/G2L uses the
normal descriptor format.
In many aspects this is not needed as the extended descriptor format is
just a normal descriptor with extra metadata (timestamsp) appended. And
the R-Car SoCs can also use normal descriptors if hardware timestamps
were not desired. This split has led to RZ/G2L gaining support for
split descriptors in the Rx path while R-Car still lacks this.
This series is the first step in trying to merge the R-Car and RZ/G2L Rx
paths so features and bugs corrected in one will benefit the other.
The first patch in the series clarifies that the driver now supports
either normal or extended descriptors, not both at the same time by
grouping them in a union. This is the foundation that later patches will
build on the aligning the two Rx paths.
Patches 2-5 deals with correcting small issues in the Rx frame and
descriptor sizes that either were incorrect at the time they were added
in 2017 (my bad) or concepts built on-top of this initial incorrect
design.
While finally patch 6 merges the R-Car and RZ/G2L for Rx descriptor
setup and maintenance.
When this work has landed I plan to follow up with more work aligning
the rest of the Rx code paths and hopefully bring split descriptor
support to the R-Car SoCs.

The R-Car and RZ/G2L Rx code paths were split in two separate
implementations when support for RZ/G2L was added due to the fact that
R-Car uses the extended descriptor format while RZ/G2L uses normal
descriptors. This has led to a duplication of Rx logic with the only
difference being the different Rx descriptors types used. The
implementation however neglects to take into account that extended
descriptors are normal descriptors with additional metadata at the end
to carry hardware timestamp information.
The hardware timestamp information is only consumed in the R-Car Rx
loop and all the maintenance code around the Rx ring can be shared
between the two implementations if the difference in descriptor length
is carefully considered.
This change merges the two implementations for Rx ring maintenance by
adding a method to access both types of descriptors as normal
descriptors, as this part covers all the fields needed for Rx ring
maintenance the only difference between using normal or extended
descriptor is the size of the memory region to allocate/free and the
step size between each descriptor in the ring.

The EtherAVB device requires the SKB data to be aligned to 128 bytes.
The alignment is done by allocating an skb 128 bytes larger than the
maximum frame size supported by the device and adjusting the headroom to
fit the requirement.
This code has been refactored a few times and small issues have been
added along the way. The issues are not harmful but prevent merging
parts of the Rx code which have been split in two implementations with
the addition of RZ/G2L support, a device that supports larger frame
sizes.
This change removes the need for duplicated and somewhat inaccurate
hardware alignment constrains stored in the hardware information struct
by creating a helper to handle the allocation of an skb and alignment of
an skb data.
For the R-Car class of devices the maximum frame size is 4K and each
descriptor is limited to 2K of data. The current implementation does not
support split descriptors, this limits the frame size to 2K. The
current hardware information however records the descriptor size just
under 2K due to bad understanding of the device when larger MTUs where
added.
For the RZ/G2L device the maximum frame size is 8K and each descriptor
is limited to 4K of data. The current hardware information records this
correctly, but it gets the alignment constrains wrong as just aligns it
by 128, it does not extend it by 128 bytes to allow the full frame to be
stored. This works because the RZ/G2L device supports split descriptors
and allocates each skb to 8K and aligns each 4K descriptor in this
space.

The Rx ring can either be made up of normal or extended descriptors, not
a mix of the two at the same time. Make this explicit by grouping the
two variables in a rx_ring union.
The extension of the storage for more than one queue of normal
descriptors from a single to NUM_RX_QUEUE queues have no practical
effect. But aids in making the code readable as the code that uses it
already piggyback on other members of struct ravb_private that are
arrays of max length NUM_RX_QUEUE, e.g. rx_desc_dma. This will also make
further refactoring easier.
While at it, rename the normal descriptor Rx ring to make it clear it's
not strictly related to the GbEthernet E-MAC IP found in RZ/G2L, normal
descriptors could be used on R-Car SoCs too.

====================
idpf: refactor virtchnl messages
Alan Brady says:
The motivation for this series has two primary goals. We want to enable
support of multiple simultaneous messages and make the channel more
robust. The way it works right now, the driver can only send and receive
a single message at a time and if something goes really wrong, it can
lead to data corruption and strange bugs.
To start the series, we introduce an idpf_virtchnl.h file. This reduces
the burden on idpf.h which is overloaded with struct and function
declarations.
The conversion works by conceptualizing a send and receive as a
"virtchnl transaction" (idpf_vc_xn) and introducing a "transaction
manager" (idpf_vc_xn_manager). The vcxn_mngr will init a ring of
transactions from which the driver will pop from a bitmap of free
transactions to track in-flight messages. Instead of needing to handle a
complicated send/recv for every a message, the driver now just needs to
fill out a xn_params struct and hand it over to idpf_vc_xn_exec which
will take care of all the messy bits. Once a message is sent and
receives a reply, we leverage the completion API to signal the received
buffer is ready to be used (assuming success, or an error code
otherwise).
At a low-level, this implements the "sw cookie" field of the virtchnl
message descriptor to enable this. We have 16 bits we can put whatever
we want and the recipient is required to apply the same cookie to the
reply for that message. We use the first 8 bits as an index into the
array of transactions to enable fast lookups and we use the second 8
bits as a salt to make sure each cookie is unique for that message. As
transactions are received in arbitrary order, it's possible to reuse a
transaction index and the salt guards against index conflicts to make
certain the lookup is correct. As a primitive example, say index 1 is
used with salt 1. The message times out without receiving a reply so
index 1 is renewed to be ready for a new transaction, we report the
timeout, and send the message again. Since index 1 is free to be used
again now, index 1 is again sent but now salt is 2. This time we do get
a reply, however it could be that the reply is _actually_ for the
previous send index 1 with salt 1. Without the salt we would have no
way of knowing for sure if it's the correct reply, but with we will know
for certain.
Through this conversion we also get several other benefits. We can now
more appropriately handle asynchronously sent messages by providing
space for a callback to be defined. This notably allows us to handle MAC
filter failures better; previously we could potentially have stale,
failed filters in our list, which shouldn't really have a major impact
but is obviously not correct. I also managed to remove fairly
significant more lines than I added which is a win in my book.
Additionally, this converts some variables to use auto-variables where
appropriate. This makes the alloc paths much cleaner and less prone to
memory leaks. We also fix a few virtchnl related bugs while we're here.

This flag is only set by one single user: the magical core dumping code
that looks up user pages one by one, and then writes them out using
their kernel addresses (by using a BVEC_ITER).
That actually ends up being a huge problem, because while we do use
copy_mc_to_kernel() for this case and it is able to handle the possible
machine checks involved, nothing else is really ready to handle the
failures caused by the machine check.
In particular, as reported by Tong Tiangen, we don't actually support
fault_in_iov_iter_readable() on a machine check area.
As a result, the usual logic for writing things to a file under a
filesystem lock, which involves doing a copy with page faults disabled
and then if that fails trying to fault pages in without holding the
locks with fault_in_iov_iter_readable() does not work at all.
We could decide to always just make the MC copy "succeed" (and filling
the destination with zeroes), and that would then create a core dump
file that just ignores any machine checks.
But honestly, this single special case has been problematic before, and
means that all the normal iov_iter code ends up slightly more complex
and slower.
See for example commit c9eec08bac96 ("iov_iter: Don't deal with
iter->copy_mc in memcpy_from_iter_mc()") where David Howells
re-organized the code just to avoid having to check the 'copy_mc' flags
inside the inner iov_iter loops.
So considering that we have exactly one user, and that one user is a
non-critical special case that doesn't actually ever trigger in real
life (Tong found this with manual error injection), the sane solution is
to just decide that the onus on handling the machine check lines on that
user instead.
Ergo, do the copy_mc_to_kernel() in the core dump logic itself, copying
the user data to a stable kernel page before writing it out.

Eric points out that our current suggested way of handling
EMSGSIZE errors ((err == -EMSGSIZE) ? skb->len : err) will
break if we didn't fit even a single object into the buffer
provided by the user. This should not happen for well behaved
applications, but we can fix that, and free netlink families
from dealing with that completely by moving error handling
into the core.
Let's assume from now on that all EMSGSIZE errors in dumps are
because we run out of skb space. Families can now propagate
the error nla_put_*() etc generated and not worry about any
return value magic. If some family really wants to send EMSGSIZE
to user space, assuming it generates the same error on the next
dump iteration the skb->len should be 0, and user space should
still see the EMSGSIZE.
This should simplify families and prevent mistakes in return
values which lead to DONE being forced into a separate recv()
call as discovered by Ido some time ago.

selftest harness uses various exit codes to signal test
results. Avoid calling exit() directly, otherwise tests
may get broken by harness refactoring (like the commit
under Fixes). SKIP() will instruct the harness that the
test shouldn't run, it used to not be the case, but that
has been fixed. So just return, no need to exit.
Note that for hmm-tests this actually changes the result
from pass to skip. Which seems fair, the test is skipped,
after all.
