net: stmmac: Add support for RZN1 GMAC devices
This is version seven of my series that adds support for a Gigabit Ethernet
controller featured in the Renesas r9a06g032 SoC, of the RZ/N1 family. This
GMAC device is based on a Synopsys IP and is compatible with the stmmac driver.
My former colleague Clément Léger originally sent a series for this driver,
but an issue in bringing up the PCS clock had blocked the upstreaming
process. This issue has since been resolved by the following series:
https://lore.kernel.org/all/[email protected]/
This series consists of a devicetree binding describing the RZN1 GMAC
controller IP, a node for the GMAC1 device in the r9a06g032 SoC device
tree, and the GMAC driver itself which is a glue layer in stmmac.
There are also two patches by Russell that improve pcs initialization handling
in stmmac.

Use the newly introduced pcs_init() and pcs_exit() operations to
create and destroy the PCS instance at a more appropriate moment during
the driver lifecycle, thereby avoiding publishing a network device to
userspace that has not yet finished its PCS initialisation.
There are other similar issues with this driver which remain
unaddressed, but these are out of scope for this patch.

Introduce a mechanism whereby platforms can create their PCS instances
prior to the network device being published to userspace, but after
some of the core stmmac initialisation has been completed. This means

A pcs_init() callback will be introduced to stmmac in a future patch. This
new function will be called during the hardware initialization phase.
Instead of separately initializing XPCS and PCS components, let's group all
PCS-related hardware initialization logic in the current
stmmac_xpcs_setup() function.
Rename stmmac_xpcs_setup() to stmmac_pcs_setup() and move the conditional
call to stmmac_xpcs_setup() inside the function itself.

Currently the XPCS handler destruction is performed in the
stmmac_mdio_unregister() method. It doesn't look good because the handler
isn't originally created in the corresponding protagonist
stmmac_mdio_unregister(), but in the stmmac_xpcs_setup() function. In
order to have more coherent MDIO and XPCS setup/cleanup procedures,
let's move the DW XPCS destruction to the dedicated stmmac_pcs_clean()
method.
This method will also be used to cleanup PCS hardware using the
pcs_exit() callback that will be introduced to stmmac in a subsequent
patch.

This driver currently doesn't support any control flags.
Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.

====================
virtio_net: rx enable premapped mode by default
Actually, for the virtio drivers, we can enable premapped mode whatever
the value of use_dma_api. Because we provide the virtio dma apis.
So the driver can enable premapped mode unconditionally.
This patch set makes the big mode of virtio-net to support premapped mode.
And enable premapped mode for rx by default.
Based on the following points, we do not use page pool to manage these
pages:
1. virtio-net uses the DMA APIs wrapped by virtio core. Therefore,
we can only prevent the page pool from performing DMA operations, and
let the driver perform DMA operations on the allocated pages.
2. But when the page pool releases the page, we have no chance to
execute dma unmap.
3. A solution to #2 is to execute dma unmap every time before putting
the page back to the page pool. (This is actually a waste, we don't
execute unmap so frequently.)
4. But there is another problem, we still need to use page.dma_addr to
save the dma address. Using page.dma_addr while using page pool is
unsafe behavior.
5. And we need space the chain the pages submitted once to virtio core.
More:
https://lore.kernel.org/all/CACGkMEu=Aok9z2imB_c5qVuujSh=vjj1kx12fy9N7hqyi+M5Ow@mail.gmail.com/
Why we do not use the page space to store the dma?

This patch adds to mlx5 drivers support for 8 ports HCAs.
Starting with ConnectX-8 HCAs with 8 ports are possible.
As most driver parts aren't affected by such configuration most driver
code is unchanged.
Specially the only affected areas are:
- Lag
- Multiport E-Switch
- Single FDB E-Switch
All of the above are already factored in generic way, and LAG and VF LAG
are tested, so all that left is to change a #define and remove checks
which are no longer needed.
However, Multiport E-Switch is not tested yet, so it is left untouched.
This patch will allow to create hardware LAG/VF LAG when all 8 ports are
added to the same bond device.
for example, In order to activate the hardware lag a user can execute
the following:
ip link add bond0 type bond
ip link set bond0 type bond miimon 100 mode 2
ip link set eth2 master bond0
ip link set eth3 master bond0
ip link set eth4 master bond0
ip link set eth5 master bond0
ip link set eth6 master bond0
ip link set eth7 master bond0
ip link set eth8 master bond0
ip link set eth9 master bond0
Where eth2, eth3, eth4, eth5, eth6, eth7, eth8 and eth9 are the PFs of
the same HCA.

There is a reference count leak issue of the object "net_device" in
ax25_dev_device_down(). When the ax25 device is shutting down, the
ax25_dev_device_down() drops the reference count of net_device one
or zero times depending on if we goto unlock_put or not, which will
cause memory leak.
In order to solve the above issue, decrease the reference count of
net_device after dev->ax25_ptr is set to null.

The ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference
count leak issue of the object "ax25_dev".
Memory leak issue in ax25_addr_ax25dev():
The reference count of the object "ax25_dev" can be increased multiple
times in ax25_addr_ax25dev(). This will cause a memory leak.
Memory leak issues in ax25_dev_device_down():
The reference count of ax25_dev is set to 1 in ax25_dev_device_up() and
then increase the reference count when ax25_dev is added to ax25_dev_list.
As a result, the reference count of ax25_dev is 2. But when the device is
shutting down. The ax25_dev_device_down() drops the reference count once
or twice depending on if we goto unlock_put or not, which will cause
memory leak.
As for the issue of ax25_addr_ax25dev(), it is impossible for one pointer
to be on a list twice. So add a break in ax25_addr_ax25dev(). As for the
issue of ax25_dev_device_down(), increase the reference count of ax25_dev
once in ax25_dev_device_up() and decrease the reference count of ax25_dev
after it is removed from the ax25_dev_list.

The origin ax25_dev_list implements its own single linked list,
which is complicated and error-prone. For example, when deleting
the node of ax25_dev_list in ax25_dev_device_down(), we have to
operate on the head node and other nodes separately.
This patch uses kernel universal linked list to replace original
ax25_dev_list, which make the operation of ax25_dev_list easier.
We should do "dev->ax25_ptr = ax25_dev;" and "dev->ax25_ptr = NULL;"
while holding the spinlock, otherwise the ax25_dev_device_up() and
ax25_dev_device_down() could race.

IPV is added and used term in 802.1Qci PSFP and merged into 802.1Q (from
802.1Q-2018) for another functions.
Even it does similar operation holding temporal priority value
internally (as it is named), because KSZ datasheet doesn't use the term
of IPV (Internal Priority Value) and avoiding any confusion later when
PSFP is in the Linux world, it is better to rename IPV to IPM (Internal
Priority Mapping).
In addition, LAN937x documentation already use IPV for 802.1Qci PSFP
related functionality.

The idea was to keep only one reset at initialization stage in order to
reduce the total delay, or the reset from usbnet_probe or the reset from
usbnet_open.
I have seen that restarting from usbnet_probe is necessary to avoid doing
too complex things. But when the link is set to down/up (for example to
configure a different mac address) the link is not correctly recovered
unless a reset is commanded from usbnet_open.
So, detect the initialization stage (first call) to not reset from
usbnet_open after the reset from usbnet_probe and after this stage, always
reset from usbnet_open too (when the link needs to be rechecked).
Apply to all the possible devices, the behavior now is going to be the same.

Pull Rust updates from Miguel Ojeda:
"The most notable change is the drop of the 'alloc' in-tree fork. This
is nicely reflected in the diffstat as a ~10k lines drop. In turn,
this makes the version upgrades way simpler and smaller in the future,
e.g. the latest one in commit 56f64b370612 ("rust: upgrade to Rust
1.78.0").
More importantly, this increases the chances that a newer compiler
version just works, which in turn means supporting several compiler
versions is easier now. Thus we will look into finally setting a
minimum version in the near future.
Toolchain and infrastructure:
- Upgrade to Rust 1.78.0
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. These allow us to remove
one more unstable feature ('offset_of') from the list, among other
improvements
- Drop 'alloc' in-tree fork of the standard library crate, which
means all the unstable features used by 'alloc' (~30 language ones,
~60 library ones) are not a concern anymore
- Support DWARFv5 via the '-Zdwarf-version' flag
- Support zlib and zstd debuginfo compression via the
'-Zdebuginfo-compression' flag
'kernel' crate:
- Support allocation flags ('GFP_*'), particularly in 'Box' (via
'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as
in the 'init' module APIs
- Remove usage of the 'allocator_api' unstable feature
- Remove 'try_' prefix in allocation APIs' names
- Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
fork
- Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'
- Add the 'as_ptr' method to 'ThisModule'
- Add the 'from_raw' method to 'ArcBorrow'
- Add the 'into_unique_or_drop' method to 'Arc'
- Display column number in the 'dbg!' macro output by applying the
equivalent change done to the standard library one
- Migrate 'Work' to '#[pin_data]' thanks to the changes in the
'macros' crate, which allows to remove an unsafe call in its 'new'
associated function
- Prevent namespacing issues when using the '[try_][pin_]init!'
macros by changing the generated name of guard variables
- Make the 'get' method in 'Opaque' const
- Implement the 'Default' trait for 'LockClassKey'
- Remove unneeded 'kernel::prelude' imports from doctests
- Remove redundant imports
'macros' crate:
- Add 'decl_generics' to 'parse_generics()' to support default
values, and use that to allow them in '#[pin_data]'
Helpers:
- Trivial English grammar fix
Documentation:
- Add section on Rust Kselftests to the 'Testing' document

For type String and Binary we are currently usinig the exact-len
limit value as is without attempting any name resolution.
However, the spec may specify the name of a constant rather than an
actual value, which would result in using the constant name as is
and thus break the policy.
Ensure the limit value is passed to get_limit(), which will always
attempt resolving the name before printing the policy rule.

A way for an application to know if an MPTCP connection fell back to TCP
is to use getsockopt(MPTCP_INFO) and look for errors. The issue with
this technique is that the same errors -- EOPNOTSUPP (IPv4) and
ENOPROTOOPT (IPv6) -- are returned if there was a fallback, *or* if the
kernel doesn't support this socket option. The userspace then has to
look at the kernel version to understand what the errors mean.
It is not clean, and it doesn't take into account older kernels where
the socket option has been backported. A cleaner way would be to expose
this info to the TCP socket level. In case of MPTCP socket where no
fallback happened, the socket options for the TCP level will be handled
in MPTCP code, in mptcp_getsockopt_sol_tcp(). If not, that will be in
TCP code, in do_tcp_getsockopt(). So MPTCP simply has to set the value
1, while TCP has to set 0.
If the socket option is not supported, one of these two errors will be
reported:
- EOPNOTSUPP (95 - Operation not supported) for MPTCP sockets
- ENOPROTOOPT (92 - Protocol not available) for TCP sockets, e.g. on the
socket received after an 'accept()', when the client didn't request to
use MPTCP: this socket will be a TCP one, even if the listen socket
was an MPTCP one.
With this new option, the kernel can return a clear answer to both "Is
this kernel new enough to tell me the fallback status?" and "If it is
new enough, is it currently a TCP or MPTCP socket?" questions, while not
breaking the previous method.
