Packet len computed as difference of length word extracted from
skb data and four may result in a negative value. In such case
processing of the buffer should be interrupted rather than
setting sr_skb->len to an unexpectedly large value (due to cast
from signed to unsigned integer) and passing sr_skb to
usbnet_skb_return.

The Microsoft Devkit 2023 is a an ARM64 based machine featuring a
Realtek 8153 USB3.0-to-GBit Ethernet adapter. As in their other
machines, Microsoft uses a custom USB device ID.
Add the respective ID values to the driver. This makes Ethernet work on
the MS Devkit device. The chip has been visually confirmed to be a
RTL8153.

This modem has 7 interfaces, 5 of them are serial interfaces and are
driven by cdc_acm, while 2 of them are wwan interfaces and are driven
by cdc_ether:
If 0: Abstract (modem)
If 1: Abstract (modem)
If 2: Abstract (modem)
If 3: Abstract (modem)
If 4: Abstract (modem)
If 5: Ethernet Networking
If 6: Ethernet Networking
Without this change, the 2 network interfaces will be named to usb0
and usb1, our QA think the names are confusing and filed a bug on it.
After applying this change, the name will be wwan0 and wwan1, and
they could work well with modem manager.

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
the implemented validation step. Consequently the response
pointer will be referring to a location past the expected
buffer boundaries allowing information leakage e.g. via
RNDIS_OID_802_3_PERMANENT_ADDRESS OID.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown". After a timer is set to this state, then it can no
longer be re-armed.
The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed. It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following
commands:
$ cat timer.cocci
@@
expression ptr, slab;
identifier timer, rfield;
@@
(
- del_timer(&ptr->timer);
+ timer_shutdown(&ptr->timer);
|
- del_timer_sync(&ptr->timer);
+ timer_shutdown_sync(&ptr->timer);
)
... when strict
when != ptr->timer
(
kfree_rcu(ptr, rfield);
|
kmem_cache_free(slab, ptr);
|
kfree(ptr);
)

ZLP for DisplayLink ethernet devices was enabled in 6.0:
266c0190aee3 ("net/cdc_ncm: Enable ZLP for DisplayLink ethernet devices").
The related driver_info should be the "same as cdc_ncm_info, but with
FLAG_SEND_ZLP". However, set_rx_mode that enables handling multicast
traffic was missing in the new cdc_ncm_zlp_info.
usbnet_cdc_update_filter rx mode was introduced in linux 5.9 with:
e10dcb1b6ba7 ("net: cdc_ncm: hook into set_rx_mode to admit multicast
traffic")
Without this hook, multicast, and then IPv6 SLAAC, is broken.

An external PHY needs settling time after power up or reset.
In the bind() function an mdio bus is registered. If at this point
the external PHY is still initialising, no valid PHY ID will be
read and on phy_find_first() the bind() function will fail.
If an external PHY is present, wait the maximum time specified
in 802.3 45.2.7.1.1.

Virtually all conventional network drivers are now converted to use
phylink_generic_validate() - only DSA drivers and fman_memac remain,
so lets remove the necessity for network drivers to explicitly set
this member, and default to phylink_generic_validate() when unset.
This is possible as .validate must currently be set.
Any remaining instances that have not been addressed by this patch can
be fixed up later.

Currently usbnet_disconnect() unanchors and frees all deferred URBs
using usb_scuttle_anchored_urbs(), which does not free urb->context,
causing a memory leak as reported by syzbot.
Use a usb_get_from_anchor() while loop instead, similar to what we did
in commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in
play_deferred"). Also free urb->sg.

The rtl8152 driver does not disable multicasting when userspace asks
it to. For example:
$ ifconfig eth0 -multicast -allmulti
$ tcpdump -p -i eth0 # will still capture multicast frames
Fix by clearing the device multicast filter table when multicast and
allmulti are both unset.
Tested as follows:
- Set multicast on eth0 network interface
- verify that multicast packets are coming in:
$ tcpdump -p -i eth0
- Clear multicast and allmulti on eth0 network interface
- verify that no more multicast packets are coming in:
$ tcpdump -p -i eth0

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as
a broken CDC device by default. Add the custom Lenovo PID to the r8152
driver to support it properly.
Also, systems compatible with this dock provide a BIOS option to enable
MAC address passthrough (as per Lenovo document "ThinkPad Docking
Solutions 2017"). Add the custom PID to the MAC passthrough list too.
Tested on a ThinkPad 13 1st gen with the expected results:
passthrough disabled: Invalid header when reading pass-thru MAC addr
passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX

There are some exotic ax88772 based devices which may require
functionality provide by the phylink framework. For example:
- US100A20SFP, USB 2.0 auf LWL Converter with SFP Cage
- AX88772B USB to 100Base-TX Ethernet (with RMII) demo board, where it
is possible to switch between internal PHY and external RMII based
connection.
So, convert this driver to phylink as soon as possible.
Tested with:
- AX88772A + internal PHY
- AX88772B + external DP83TD510E T1L PHY

This reverts commit 36a15e1cb134c0395261ba1940762703f778438c.
The usage of FLAG_SEND_ZLP causes problems to other firmware/hardware
versions that have no issues.
The FLAG_SEND_ZLP is not safe to use in this context.
See:
https://patchwork.ozlabs.org/project/netdev/patch/1270599787.8900.8.camel@Linuxdev4-laptop/#118378
The original problem needs another way to solve.

The Anker PowerExpand USB-C to Gigabit Ethernet adapter uses this
chipset, but exposes CDC Ethernet configurations as well as the
vendor specific one. This driver tries to bind by PID:VID
unconditionally and ends up picking up the CDC configuration, which
is supposed to be handled by the class driver. To make things even
more confusing, it sees both of the CDC class interfaces and tries
to bind twice, resulting in two broken Ethernet devices.
Change all the ID matches to specifically match the vendor-specific
interface. By default the device comes up in CDC mode and is bound by
that driver (which works fine); users may switch it to the vendor
interface using sysfs to set bConfigurationValue, at which point the
device actually goes through a reconnect cycle and comes back as a
vendor specific only device, and then this driver binds and works too.
The affected device uses VID/PID 0b95:1790, but we might as well change
all of them for good measure, since there is no good reason for this
driver to bind to standard CDC Ethernet interfaces.

This refixes:
commit 7da17624e7948d5d9660b910f8079d26d26ce453
nt: usb: USB_RTL8153_ECM should not default to y
In general, device drivers should not be enabled by default.
which basically broke the commit it claimed to fix, ie:
commit 657bc1d10bfc23ac06d5d687ce45826c760744f9
r8153_ecm: avoid to be prior to r8152 driver
Avoid r8153_ecm is compiled as built-in, if r8152 driver is compiled
as modules. Otherwise, the r8153_ecm would be used, even though the
device is supported by r8152 driver.
this commit amounted to:
drivers/net/usb/Kconfig:
+config USB_RTL8153_ECM
+ tristate "RTL8153 ECM support"
+ depends on USB_NET_CDCETHER && (USB_RTL8152 || USB_RTL8152=n)
+ default y
+ help
+ This option supports ECM mode for RTL8153 ethernet adapter, when
+ CONFIG_USB_RTL8152 is not set, or the RTL8153 device is not
+ supported by r8152 driver.
drivers/net/usb/Makefile:
-obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o r8153_ecm.o
+obj-$(CONFIG_USB_NET_CDCETHER) += cdc_ether.o
+obj-$(CONFIG_USB_RTL8153_ECM) += r8153_ecm.o
And as can be seen it pulls a piece of the cdc_ether driver out into
a separate config option to be able to make this piece modular in case
cdc_ether is builtin, while r8152 is modular.
While in general, device drivers should indeed not be enabled by default:
this isn't a device driver per say, but rather this is support code for
the CDCETHER (ECM) driver, and should thus be enabled if it is enabled.

And when we say "removed" we can just hide it from what's prompted

this way we don't bring back Marek's complaint.
Side note: these incorrect defaults will result in Android 13
on 5.15 GKI kernels lacking USB_RTL8153_ECM support while having
USB_NET_CDCETHER (luckily we also have USB_RTL8150 and USB_RTL8152,
so it's probably only an issue for very new RTL815x hardware with
no native 5.15 driver).

We need more space to save WoL context. So lets allocate memory
for ax88179_data instead of using struct usbnet data field which
only supports 5 words. We continue to use the struct usbnet data
field for multicast filters. However since we no longer have the
private data stored there, we can shift it to the beginning.
