Benar juga dugaan saya kemarin ..., kutunya ada di fungsi ...
LUKS_open_key() di keymanage.c
kalau return nya diganti == (return 1)
jadi langsung bisa ...., hehe ...
ketika googling ada yang bilang memcmp di uclibnya ada bugsnya, tapi
tertanggal 2004, seharus nya skrg tidak masalah lagi ...
berarti sekarang konsentrasi mencari kenapa variabel checkHashBuf dan
hdr->mkDigest, di
r = (memcmp(checkHashBuf,hdr->mkDigest, LUKS_DIGESTSIZE) == 0)?0:-EPERM;
berbeda ...
Output junk Code nya kalau return nya di ubah jadi 1, menjadi seperti ini :
