[PATCH] xen-netfront: handle NULL returned by xdp_convert_buff_to_frame()

by Alexey Nepomnyashih

The function xdp_convert_buff_to_frame() may return NULL if it fails to correctly convert the XDP buffer into an XDP frame due to memory constraints, internal errors, or invalid data. Failing to check for NULL may lead to a NULL pointer dereference if the result is used later in processing, potentially causing crashes, data corruption, or undefined behavior.

[PATCH v2] drm/amd/pm/powerplay/smumgr/fiji_smumgr: Add error check in fiji_populate_smc_boot_level()

by Wentao Liang

The return value of fiji_populate_smc_boot_level() is needs to be checked. An error handling is also needed to phm_find_boot_level() to reset the boot level when the function fails.

[PATCH net 1/2] amd-xgbe: Fix data loss when RX checksum offloading is disabled

by Vishal Badole

To properly disable checksum offloading, the split header mode must also be disabled. When split header mode is disabled, the network device stores received packets (with size <= 1536 bytes) entirely in buffer1, leaving buffer2 empty. However, with the current DMA configuration, only 256 bytes from buffer1 are copied from the network device to system memory, resulting in the loss of the remaining packet data. Address the issue by programming the ARBS field to 256 bytes, which aligns with the socket buffer size, and setting the SPH bit in the control register to disable split header mode. With this configuration, the network device stores the first 256 bytes of the received packet in buffer1 and the remaining data in buffer2. The DMA is then able to transfer the full packet from the network device to system memory without any data loss.
