__skb_recv_datagram - Receive a datagram skbuff
SYNOPSIS
struct sk_buff * __skb_recv_datagram(struct sock * sk, unsigned flags, int * peeked, int * err);
ARGUMENTS
sk
socket
flags
MSG_ flags
peeked
returns non-zero if this packet has been seen before
err
error code returned
DESCRIPTION
Get a datagram skbuff, understands the peeking, nonblocking wakeups and possible races. This replaces identical code in packet, raw and
udp, as well as the IPX AX.25 and Appletalk. It also finally fixes the long standing peek and read race for datagram sockets. If you alter
this routine remember it must be re-entrant.
This function will lock the socket if a skb is returned, so the caller needs to unlock the socket in that case (usually by calling
skb_free_datagram)
* It does not lock socket since today. This function is * free of race conditions. This measure should/can improve * significantly datagram
socket latencies at high loads, * when data copying to user space takes lots of time. * (BTW I've just killed the last cli in
IP/IPv6/core/netlink/packet * 8) Great win.) * --ANK (980729)
The order of the tests when we find no data waiting are specified quite explicitly by POSIX 1003.1g, don't change them without having the
standard around please.
