2011-09-03Use new macro QEMU_PACKED for packed structuresStefan Weil1-1/+1
Most changes were made using these commands: git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/' git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/' git grep -la '__attribute__((__packed__))'|xargs perl -pi -e 's/__attribute__\(\(__packed__\)\)/QEMU_PACKED/' git grep -la '__attribute__ ((__packed__))'|xargs perl -pi -e 's/__attribute__ \(\(__packed__\)\)/QEMU_PACKED/' git grep -la '__attribute((packed))'|xargs perl -pi -e 's/__attribute\(\(packed\)\)/QEMU_PACKED/' Whitespace in linux-user/syscall_defs.h was fixed manually to avoid warnings from scripts/checkpatch.pl. Manual changes were also applied to hw/pc.c. I did not fix indentation with tabs in block/vvfat.c. The patch will show 4 errors with scripts/checkpatch.pl.

2011-08-05slirp: Fix types of IP address parametersJan Kiszka1-2/+2
Should be uint32_t for IPv4, not int. Also avoid in_addr_t without proper includes. Fixes build regression on mingw32. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2011-07-23slirp: Forward ICMP echo requests via unprivileged socketsJan Kiszka1-0/+5
Linux 3.0 gained support for unprivileged ICMP ping sockets. Use this feature to forward guest pings to the outer world. The host admin has to set the ping_group_range in order to grant access to those sockets. To allow ping for the users group (GID 100): echo 100 100 > /proc/sys/net/ipv4/ping_group_range Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-11-21slirp: Remove unused code for bad sprintfStefan Weil1-14/+0
Neither DECLARE_SPRINTF nor BAD_SPRINTF are needed for QEMU. QEMU won't support systems with missing or bad declarations for sprintf. The unused code was detected while looking for functions with missing format checking. Instead of adding GCC_FMT_ATTR, the unused code was removed.

2010-07-25slirp: Remove declarations which are no longer neededStefan Weil1-33/+0
The previous patches replaced u_int8_t, u_int16_t, u_int32_t, u_int64_t by standard int types from stdint.h, so we can now remove their declarations which are no longer needed. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl1-2/+2
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>
2009-07-27slirp: Use monotonic clock if available (v2)Ed Swierk1-4/+0
Calling gettimeofday() to compute a time interval can cause problems if the system clock jumps forwards or backwards; replace updtime() with qemu_get_clock(rt_clock), which calls clock_gettime(CLOCK_MONOTONIC) if it is available. Also remove some useless macros. Signed-off-by: Ed Swierk <eswierk@aristanetworks.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-06-29slirp: Enable multiple instancesJan Kiszka1-0/+4
Once again this was a long journey to reach the destination: Allow to instantiate slirp multiple times. But as in the past, the journey was worthwhile, cleaning up, fixing and enhancing various parts of the user space network stack along the way. What is this particular change good for? Multiple slirps instances allow separated user space networks for guests with multiple NICs. This is already possible, but without any slirp support for the second network, ie. without a chance to talk to that network from the host via IP. We have a legacy guest system here that benefits from this slirp enhancement, allowing us to run both of its NICs purely over unprivileged user space IP stacks. Another benefit of this patch is that it simply removes an artificial restriction of the configuration space qemu is providing, avoiding another source of surprises that users may face when playing with possible setups.

2009-06-29slirp: Allocate/free stack instance dynamicallyJan Kiszka1-1/+1
Allocate the internal slirp state dynamically and provide and call slirp_cleanup to properly release it after use. This patch finally unbreaks slirp release and re-instantiation via host_net_* monitor commands. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Use internal state in interfaceJan Kiszka1-0/+1
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 Kiszka1-6/+60
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 statistic codeJan Kiszka1-9/+0
As agreed on the mailing list, there is no interest in keeping the usually disabled slirp statistics in the tree. So this patch removes them. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Drop dead codeJan Kiszka1-7/+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>
2009-06-29slirp: Rework internal configurationJan Kiszka1-1/+0
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.
