2010-05-18qemu-sockets: avoid strlen of NULL pointerJens Osterkamp1-1/+2
If the user wants to create a chardev of type socket but forgets to give a host= option, qemu_opt_get returns NULL. This NULL pointer is then fed into strlen a few lines below without a check which results in a segfault. This fixes it.

2009-12-03Don't leak file descriptorsKevin Wolf1-5/+5
We're leaking file descriptors to child processes. Set FD_CLOEXEC on file descriptors that don't need to be passed to children to stop this misbehaviour. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl1-1/+1
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

While being at it: create a new inet_dgram_opts() function for udp setup, so udp can handle IPv6 now. new cmd line syntax: -chardev udp,id=name,host=remotehost,port=remoteport,\ localaddr=bindaddr,localport=bindport Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2008-11-11sockets: helper functions for qemu (Gerd Hoffman)aliguori1-0/+400
This patch creates a new source file qemu-sockets.c with a bunch of helper functions to create listening and connected sockets. New features of this code are (a) support for searching for a free port in a given range and (b) support for IPv6. The following patches put that code into use.
