perf_event_write_value_at_address function

[ali-zohrevand]

hi a gain ... :)) in line 164 in perf_event.c we have a while ... why you choose minimum of (value, PERF_SWEVENT_MAX_FILE)? and then you value -= PERF_SWEVENT_MAX_FILE every time? value is the address of commit_creds(prepare_kernel_cred(0)) .right? so why you Subtract it from PERF_SWEVENT_MAX_FILE? thanks a lot for helping

Hello,

As I said before, your question is about https://github.com/android-rooting-tools/libperf_event_exploit

Please ask there.

so why you Subtract it from PERF_SWEVENT_MAX_FILE?

This is wrong. You need to learn C language first anyway.

Please upgrade your knowledge about C language before opening issue there. Your question is not related to the exploit.
