2011-08-05slirp: Only start packet expiration for delayed onesJan Kiszka
The expiration timeout must only affect packets that are queued due to pending ARP resolutions. The old version broke ping e.g. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2011-08-05slirp: Read current time only once per if_start callJan Kiszka
No need to update the current time for each packet we send from the queue. Processing time is comparably short. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2011-08-03Delayed IP packetsFabien Chouteau
In the current implementation, if Slirp tries to send an IP packet to a client with an unknown hardware address, the packet is simply dropped and an ARP request is sent (if_encap in slirp/slirp.c). With this patch, Slirp will send the ARP request, re-queue the packet and try to send it later. The packet is dropped after one second if the ARP reply is not received.

2009-06-29slirp: Use internal state in interfaceJan Kiszka
This now also exports the internal state to the slirp users in qemu, returning it from slirp_init and expecting it along with service invocations. Additionally provide an opaque value interface for the callbacks from slirp into the qemu core. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Factor out internal state structureJan Kiszka
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.

2009-06-29slirp: Drop link_up checks from if_output and slirp_socket_can_recvJan Kiszka
link_up is true once slirp is initialized, so these check are really not required. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Drop dead codeJan Kiszka
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>
