Subject: [RFC] Netlink and user-space buffer pointers
Date: Wed, 19 Apr 2006 08:57:25 -0400 [thread overview]
Message-ID: <444633B5.5030208@emulex.com> (raw)

Folks,
To take netlink to where we want to use it within the SCSI subsystem (as
the mechanism of choice to replace ioctls), we're going to need to pass
user-space buffer pointers.
What is the best, portable manner to pass a pointer between user and kernel
space within a netlink message ? The example I've seen is in the iscsi
target code - and it's passed between user-kernel space as a u64, then
typecast to a void *, and later within the bio_map_xxx functions, as an
unsigned long. I assume we are going to continue with this method ?
