Hello,
I need to access the address space of Process say P2 from
Process P1 while trying to take a complete dump of P2 (I have to
migrate P2 to a remote machine) . I have the process descriptor of P2
available in P1. Using this proc_desc I got the addresses of the
vm_areas associated with P2 but I realized that I will not be able to
use these directly to access the memory regions. Since the local page
descriptor table for P1 will not be having the corresponding entries. I
just require the read permissions for memory regions of P2. Could
somebody please give me hints on the following :
1. Where exactly should I look for the Hardware pages of P2?
2. Will it be sufficient to get the handle of the hardware pages and
then read from the same ?
3. Can I map the memory regions of P2 in P1 and if so then how ?
Any suggestions would be welcome.
Thanks in Advance,
Anant
