2010-07-25slirp: Replace u_int8_t, u_int16_t, u_int32_t, u_int64_t by standard int typesStefan Weil
There is no need to have a second set of integral types. Replace them by the standard types from stdint.h. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-20slirp: fix structure initialization in tcp_listen()Juha Riihimäki
A data structure of type sockaddr_in is allocated from stack but not properly initialized. This may lead to a failure in the bind() call later on. Fixed by filling the contents of the structure with zeroes before using it. Signed-off-by: Juha Riihimäki <juha.riihimaki@nokia.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-12-03Don't leak file descriptorsKevin Wolf
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>
2009-08-27slirp: Read host DNS config on demandEd Swierk
Currently the qemu user-mode networking stack reads the host DNS configuration (/etc/resolv.conf or the Windows equivalent) only once when qemu starts. This causes name lookups in the guest to fail if the host is moved to a different network from which the original DNS servers are unreachable, a common occurrence when the host is a laptop. This patch changes the slirp code to read the host DNS configuration on demand, caching the results for at most 1 second to avoid unnecessary overhead if name lookups occur in rapid succession. On non-Windows hosts, /etc/resolv.conf is re-read only if the file has been replaced or if its size or mtime has changed.

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 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>
2009-06-29slirp: Prepare for persistent socket state flagsJan Kiszka
This prepares for adding flags to socket.so_state that must not be removed during the lifetime of a socket. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Bind support for host forwarding rulesJan Kiszka
Extend the hostfwd rule format so that the user can specify on which host interface qemu should listen for incoming connections. If omitted, binding will takes place against all interfaces. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Rework internal configurationJan Kiszka
The user mode IP stack is currently only minimally configurable /wrt to its virtual IP addresses. This is unfortunate if some guest has a fixed idea of which IP addresses to use. Therefore this patch prepares the stack for fully configurable IP addresses and masks. The user interface and default addresses remain untouched in this step, they will be enhanced in the following patch.
