staging: rtl*: Remove tasklet callback casts 2019-11-16T13:41:02+00:00 Kees Cook keescook@chromium.org 2019-11-15T17:28:28+00:00 6cfed598480493d814414ce7e53027bd6fc45c49 In order to make the entire kernel usable under Clang's Control Flow Integrity protections, function prototype casts need to be avoided because this will trip CFI checks at runtime (i.e. a mismatch between the caller's expected function prototype and the destination function's prototype). Many of these cases can be found with -Wcast-function-type, which found that the rtl wifi drivers had a bunch of needless function casts. Remove function casts for tasklet callbacks in the various drivers.

However, after that, skb is accessed again to read its length, which may result in a use after free bug. This patch fixes the bug by moving the release operation to where skb is never used later.
