staging: rtl8192e: Annotate struct rtllib_txb with __counted_by

2023-08-22T13:48:05+00:00

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct rtllib_txb.

staging: rtl8192e: Remove unsupported mode IW_MODE_MESH

2023-08-22T13:44:31+00:00

Tasklet irq_rx_tasklet is scheduled when hw is receiving frames. Function _rtl92e_irq_rx_tasklet() is then called which calls then _rtl92e_rx_normal(). In _rtl92e_rx_normal() all frames are processed by rtllib_rx(). When ieee->iw_mode is IW_MODE_MESH the function returns 0. The calling function then calls: dev_kfree_skb_any() which clears the skb. So the driver clears all packets received in this mode. Remove dead code in mode IW_MODE_MESH.
