check if a kernel page is read-only

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I'm writing a module to read/write kernel memory, and for this I'd like to check if a page is marked as read-only, so we don't have the right to write there (kernel code for instance).

I though about the flags field from "struct page {}", but from the name I can't see any useful flag to check this.

The only flag I saw is different between kernel code and module code is that kernel code has the flag "reserved" enabled, so it's not swapped.

Could someone provide me a hint about that?

Thank you very much
