2020-02-10staging: rtl8188eu: Remove some unneeded goto statementsLarry Finger
In routines rtw_hostapd_ioctl() and wpa_supplicant_ioctl(), several error conditions involve setting a variable indicating the error, followed by a goto. The code following the target of that goto merely returns the value. It is simpler, therefore to return the error value immediately, and eliminate the got target.

2020-02-10staging: rtl8188eu: Fix potential overuse of kernel memoryLarry Finger
In routine wpa_supplicant_ioctl(), the user-controlled p->length is checked to be at least the size of struct ieee_param size, but the code does not detect the case where p->length is greater than the size of the struct, thus a malicious user could be wasting kernel memory. Fixes commit a2c60d42d97c ("Add files for new driver - part 16").

2020-02-10staging: rtl8188eu: Fix potential security holeLarry Finger
In routine rtw_hostapd_ioctl(), the user-controlled p->length is assumed to be at least the size of struct ieee_param size, but this assumption is never checked. This could result in out-of-bounds read/write on kernel heap in case a p->length less than the size of struct ieee_param is specified by the user. If p->length is allowed to be greater than the size of the struct, then a malicious user could be wasting kernel memory. Fixes commit a2c60d42d97c ("Add files for new driver - part 16").

2019-11-16staging: rtl*: Remove tasklet callback castsKees Cook
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.

Internally, we use this driver as builtin [vs kmod], and we've identified the `efuse_power_switch()` symbol to be conflicting at link-time with the one from the `rtlwifi` driver. An alternative solution would have been to rename the function, but it doesn't look like it's being used outside of this driver, so just make it static.
