1) Introduce a new socket option, (SOL_SOCKET, SO_NOHEADER), that
tells a socket that it should both add a protocol header to tx'd
datagrams and remove the header from rx'd datagrams:
int onoff = 1, s = socket(...);
setsockopt(s, SOL_SOCKET, SO_NOHEADER, &onoff);
2) Add an implementation of (SOL_SOCKET, SO_NOHEADER) for raw IPv4
sockets.
3) Reorganize the protocols' pr_ctloutput implementations a bit.
Consistently return ENOPROTOOPT when an option is unsupported,
and EINVAL if a supported option's arguments are incorrect.
Reorganize the flow of code so that it's more clear how/when
options are passed down the stack until they are handled.
Shorten some pr_ctloutput staircases for readability.
4) Extract common mbuf code into subroutines, add new sockaddr
methods, and introduce a new subroutine, fsocreate(), for reuse
later; use it first in sys_socket():
struct mbuf *m_getsombuf(struct socket *so)
Create an mbuf and make its owner the socket `so'.
struct mbuf *m_intopt(struct socket *so, int val)
Create an mbuf, make its owner the socket `so', put the
int `val' into it, and set its length to sizeof(int).
int fsocreate(..., int *fd)
Create a socket, a la socreate(9), put the socket into the
given LWP's descriptor table, return the descriptor at `fd'
on success.
void *sockaddr_addr(struct sockaddr *sa, socklen_t *slenp)
const void *sockaddr_const_addr(const struct sockaddr *sa, socklen_t *slenp)
Extract a pointer to the address part of a sockaddr. Write
the length of the address part at `slenp', if `slenp' is
not NULL.
socklen_t sockaddr_getlen(const struct sockaddr *sa)
Return the length of a sockaddr. This just evaluates to
sa->sa_len. I only add this for consistency with code that
appears in a portable userland library that I am going to
import.
const struct sockaddr *sockaddr_any(const struct sockaddr *sa)
Return the "don't care" sockaddr in the same family as
`sa'. This is the address a client should sobind(9) if it
does not care the source address and, if applicable, the
port et cetera that it uses.
const void *sockaddr_anyaddr(const struct sockaddr *sa, socklen_t *slenp)
Return the "don't care" sockaddr in the same family as
`sa'. This is the address a client should sobind(9) if it
does not care the source address and, if applicable, the
port et cetera that it uses.
