net: introduce helper macro for_each_cmsghdr

2014-12-11T03:41:55Z

Introduce helper macro for_each_cmsghdr as a wrapper of the enumerating cmsghdr from msghdr, just cleanup. Signed-off-by: Gu Zheng Signed-off-by: David S. Miller

put iov_iter into msghdr

2014-12-09T21:29:03Z

Note that the code _using_ ->msg_iter at that point will be very unhappy with anything other than unshifted iovec-backed iov_iter. We still need to convert users to proper primitives. Signed-off-by: Al Viro

separate kernel- and userland-side msghdr

2014-11-19T21:22:59Z

Kernel-side struct msghdr is (currently) using the same layout as userland one, but it's not a one-to-one copy - even without considering 32bit compat issues, we have msg_iov, msg_name and msg_control copied to kernel[1]. It's fairly localized, so we get away with a few functions where that knowledge is needed (and we could shrink that set even more). Pretty much everything deals with the kernel-side variant and the few places that want userland one just use a bunch of force-casts to paper over the differences. The thing is, kernel-side definition of struct msghdr is *not* exposed in include/uapi - libc doesn't see it, etc. So we can add struct user_msghdr, with proper annotations and let the few places that ever deal with those beasts use it for userland pointers. Saner typechecking aside, that will allow to change the layout of kernel-side msghdr - e.g. replace msg_iov/msg_iovlen there with struct iov_iter, getting rid of the need to modify the iovec as we copy data to/from it, etc. We could introduce kernel_msghdr instead, but that would create much more noise - the absolute majority of the instances would need to have the type switched to kernel_msghdr and definition of struct msghdr in include/linux/socket.h is not going to be seen by userland anyway. This commit just introduces user_msghdr and switches the few places that are dealing with userland-side msghdr to it. [1] actually, it's even trickier than that - we copy msg_control for sendmsg, but keep the userland address on recvmsg. Signed-off-by: Al Viro

iovec: move memcpy_from/toiovecend to lib/iovec.c

2014-06-27T18:47:58Z

ERROR: "memcpy_fromiovecend" [drivers/vhost/vhost_scsi.ko] undefined! commit 9f977ef7b671f6169eca78bf40f230fe84b7c7e5 vhost-scsi: Include prot_bytes into expected data transfer length in target-pending makes drivers/vhost/scsi.c call memcpy_fromiovecend(). This function is not available when CONFIG_NET is not enabled. socket.h already includes uio.h, so no callers need updating. Reported-by: Randy Dunlap Cc: Stephen Rothwell Cc: "David S.
