2023-03-17net: lan78xx: fix accessing the LAN7800's internal phy specific registers ↵Yuiko Oshino1-26/+1
from the MAC driver [ Upstream commit e57cf3639c323eeed05d3725fd82f91b349adca8 ] Move the LAN7800 internal phy (phy ID 0x0007c132) specific register accesses to the phy driver (microchip.c). Fix the error reported by Enguerrand de Ribaucourt in December 2022, "Some operations during the cable switch workaround modify the register LAN88XX_INT_MASK of the PHY. However, this register is specific to the LAN8835 PHY. For instance, if a DP8322I PHY is connected to the LAN7801, that register (0x19), corresponds to the LED and MAC address configuration, resulting in unapropriate behavior." I did not test with the DP8322I PHY, but I tested with an EVB-LAN7800 with the internal PHY.

2023-02-22net/usb: kalmia: Don't pass act_len in usb_bulk_msg error pathMiko Larsson1-4/+4
commit c68f345b7c425b38656e1791a0486769a8797016 upstream. syzbot reported that act_len in kalmia_send_init_packet() is uninitialized when passing it to the first usb_bulk_msg error path. Jiri Pirko noted that it's pointless to pass it in the error path, and that the value that would be printed in the second error path would be the value of act_len from the first call to usb_bulk_msg.[1] With this in mind, let's just not pass act_len to the usb_bulk_msg error paths. 1: https://lore.kernel.org/lkml/Y9pY61y1nwTuzMOa@nanopsycho/ Fixes: d40261236e8e ("net/usb: Add Samsung Kalmia driver for Samsung GT-B3730") Reported-and-tested-by: syzbot+cd80c5ef5121bfe85b55@syzkaller.appspotmail.com Signed-off-by: Miko Larsson <mikoxyzzz@gmail.com> Reviewed-by: Alexander Duyck <alexanderduyck@fb.com> Signed-off-by: David S.

Setting off to a unexpectetly large value will cause the sum with len and 8 to overflow and pass the implemented validation step.

2022-08-27r8152: add PID for the Lenovo OneLink+ DockJean-Francois Le Fillatre2-0/+10
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 Signed-off-by: Jean-Francois Le Fillatre <jflf_kernel@gmx.com> Signed-off-by: David S.

2022-08-02net: usb: ax88179_178a: Bind only to vendor-specific interfaceHector Martin1-13/+13
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. v3: Added VID/PID info to commit message Signed-off-by: Hector Martin <marcan@marcan.st> Link: https://lore.kernel.org/r/20220731072209.45504-1-marcan@marcan.st Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2022-08-02net: usb: make USB_RTL8153_ECM non user configurableMaciej Żenczykowski1-1/+2
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. See also email thread at: https://www.spinics.net/lists/netdev/msg767649.html In: https://www.spinics.net/lists/netdev/msg768284.html Jakub wrote: And when we say "removed" we can just hide it from what's prompted to the user (whatever such internal options are called)? I believe 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).
