* slirp: switch to GPollFDStefan Hajnoczi2013-02-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Slirp uses rfds/wfds/xfds more extensively than other QEMU components. The rarely-used out-of-band TCP data feature is used. That means we need the full table of select(2) to g_poll(3) events: rfds -> G_IO_IN | G_IO_HUP | G_IO_ERR wfds -> G_IO_OUT | G_IO_ERR xfds -> G_IO_PRI I came up with this table by looking at Linux fs/select.c which maps select(2) to poll(2) internally. Another detail to watch out for are the global variables that reference rfds/wfds/xfds during slirp_select_poll(). sofcantrcvmore() and sofcantsendmore() use these globals to clear fd_set bits. When sofcantrcvmore() is called, the wfds bit is cleared so that the write handler will no longer be run for this iteration of the event loop. This actually seems buggy to me since TCP connections can be half-closed and we'd still want to handle data in half-duplex fashion. I think the real intention is to avoid running the read/write handler when the socket has been fully closed. This is indicated with the SS_NOFDREF state bit so we now check for it before invoking the TCP write handler. Note that UDP/ICMP code paths don't care because they are connectionless. Note that slirp/ has a lot of tabs and sometimes mixed tabs with spaces. I followed the style of the surrounding code.

* slirp: Factor out internal state structureJan Kiszka2009-06-291-4/+5
| | | | | | | | | | | The essence of this patch is to stuff (almost) all global variables of the slirp stack into the structure Slirp. In this step, we still keep the structure as global variable, directly accessible by the whole stack. Changes to the external interface of slirp will be applied in the following patches.

* slirp: Drop dead codeJan Kiszka2009-06-291-4/+0
| | | | | | | | | | After all its years inside the qemu tree, there is no point in keeping the dead code paths of slirp. This patch is a first round of removing usually commented out code parts. More cleanups need to follow (and maybe finally a proper reindention). Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
