Hello,
I'm having trouble reading from /dev/kmem in Linux 2.4.22 and 2.4.25. I have written some code available at http://vv.carleton.ca/~cat/misc/readidt.c. The behavior on both kernel versions is the following:
# ./readidt idt: 0xffffe000 + 0x07ff pointer at 0x00000000ffffe400 read: 0
As read returns 0, it seems as if it's reading past the end of file. However, the IDT must be present in the kernel's virtual memory. Also, looking at 2.4.20's read_kmem() (drivers/char/mem.c:215), I don't see how the function could return 0 unless count was 0.
It would be great if follow-ups could be CC'ed to my e-mail address.
Thank you very much for your time, Catalin
