MAC Randomization causing compile issue #41

Closed gteca closed 3 years ago

gteca commented 3 years ago

Hi, I am running in Linux 20.04 I am trying to use MAC randomization by defining the macro #CONFIG_RTW_CFGVENDOR_RANDOM_MAC_OUI in drv.types.h, but during compilation I get: ERROR: modpost: "rtw_hal_set_pno_random_get_mac_addr" [full_path] undefined! ERROR: modpost: "rtw_hal_set_hw_mac_addr" [full_path] undefined!

Since #42 was solved and closed, does that mean this report should also be closed?

This issue is still opened, the #42 was my workaround to the problem, like reinvent the wheel

Go to the Makefile and change this setting

CONFIG_RTW_WIFI_HAL = n

Good luck.

Checking to see if you got the above message.

Hi @morrownr , In Makefile I changed CONFIG_RTW_WIFI_HAL = y, because above there is EXTRA_CFLAGS += -DCONFIG_RTW_CFGVENDOR_RANDOM_MAC_OUI, loaded new module, no compilation error everything finished well, but when scanning the probe requests from the adapter but the MAC is still from the manufacturer, I will keep trying and let you know if something changes.

I will close the issue because I found I way to do it, I hope it helps others: rtw_random32() generates a 32-bit integer which is fine and I can build my own random mac also, and the kernel uses the same function, to make sure, I recommend using RTW_INFO logger to make sure what numbers are being generated.
