| |
I wished someone to confirm the following: Is it a requirement for the user space buffer that is provided to the recvfrom() socket call, be 4 byte aligned?. Note that sockets are raw sockets (PF_PACKET type). I am running linux 2.4.18-10 on a dual xeon P4 (x86) box. At the lowest level, i think this translates to how strong the requirements are for copy_to_user(). does it fault to byte-by-byte mode gracefully when given a non-4byte aligned buffer?.
Please include me in all replies, since i'm not subscribed to the list
Thanks -Arvind
