[PATCH net] llc: fix data loss when reading from a socket in llc_ui_recvmsg()

For SOCK_STREAM sockets, if user buffer size (len) is less than skb size (skb->len), the remaining data from skb will be lost after calling kfree_skb().

[PATCH 0/5] net: ch9200: fix various bugs and improve qinheng ch9200 driver

by Qasim Ijaz

This patch series aims to fix various issues throughout the QinHeng CH9200 driver. This driver fails to handle various failures, which in one case has lead to a uninit access bug found via syzbot. Upon reviewing the driver I fixed a few more issues which I have included in this patch series. Parts of this series are the product of discussions and suggestions I had from others like Andrew Lunn, Simon Horman and Jakub Kicinski you can view those discussions below: Link: <https://lore.kernel.org/all/20250319112156.48312-1-qasdev00@gmail.com> Link: <https://lore.kernel.org/all/20250218002443.11731-1-qasdev00@gmail.com/> Link: <https://lore.kernel.org/all/20250311161157.49065-1-qasdev00@gmail.com/> Qasim Ijaz (5): fix uninitialised access bug during mii_nway_restart remove extraneous return that prevents error propagation fail fast on control_read() failures during get_mac_address() add missing error handling in ch9200_bind() avoid triggering NWay restart on non-zero PHY ID drivers/net/usb/ch9200.c | 61 ++++++++++++++++++++++++++-------------- 1 file changed, 40 insertions(+), 21 deletions(-) -- 2.39.5

[PATCH] dummycon: Trigger redraw when switching consoles with deferred takeover

by Thomas Zimmermann

Signal vt subsystem to redraw console when switching to dummycon with deferred takeover enabled. Makes the console switch to fbcon and displays the available output. With deferred takeover enabled, dummycon acts as the placeholder until the first output to the console happens. At that point, fbcon takes over. If the output happens while dummycon is not active, it cannot inform fbcon. This is the case if the vt subsystem runs in graphics mode. A typical graphical boot starts plymouth, a display manager and a compositor; all while leaving out dummycon. Switching to a text-mode console leaves the console with dummycon even if a getty terminal has been started. Returning true from dummycon's con_switch helper signals the vt subsystem to redraw the screen. If there's output available dummycon's con_putc{s} helpers trigger deferred takeover of fbcon, which sets a display mode and displays the output. If no output is available, dummycon remains active.

[PATCH V2 1/2] phy: tegra: xusb: Decouple CYA_TRK_CODE_UPDATE_ON_IDLE from trk_hw_mode

by Wayne Chang

The logic that drives the pad calibration values resides in the controller reset domain and so the calibration values are only being captured when the controller is out of reset. However, by clearing the CYA_TRK_CODE_UPDATE_ON_IDLE bit, the calibration values can be set while the controller is in reset. The CYA_TRK_CODE_UPDATE_ON_IDLE bit was previously cleared based on the trk_hw_mode flag, but this dependency is not necessary. Instead, introduce a new flag, trk_update_on_idle, to independently control this bit.

[PATCH v3] wifi: wilc1000: Add error handling for wilc_sdio_cmd52()

The wilc_sdio_read_size() calls wilc_sdio_cmd52() but does not check the return value. This could lead to execution with potentially invalid data if wilc_sdio_cmd52() fails.

The function mlx5_query_nic_vport_node_guid() calls the functuion mlx5_query_nic_vport_context() but does not check its return value. A proper implementation can be found in mlx5_nic_vport_query_local_lb(). Add error handling for mlx5_query_nic_vport_context(). If it fails, free the out buffer via kvfree() and return error code.
