Message-ID: <20120823130617.GF14639@Latty> (raw)
Hi all,
When tracking mmaps from LSM with the following hook:
static int file_mmap(struct file *file, unsigned long reqprot,
unsigned long prot, unsigned long flags,
unsigned long addr, unsigned long addr_only);
I often get:
file = NULL
flags = 0x0 (MAP_FILE)
prot = 0x0 (PROT_NONE)
I am wondering what is the use for mmap with MAP_FILE and PROT_NONE together ?
Not sure how to interpret that ?
