2013-07-15tools/lguest: offer VIRTIO_F_ANY_LAYOUT for net device.Rusty Russell
We don't care about layout, so advertise that fact. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2013-07-04lguest: fix example launcher compilation for broken glibc headers.Rusty Russell
Somehow a naked u16 slipped into the glibc headers on my Ubuntu machine (i386 2.17-0ubuntu5), breaking compile: In file included from lguest.c:46:0: /usr/include/linux/virtio_net.h:188:2: error: unknown type name ‘u16’ We use the kernel-style types anyway, just define them before the includes. Also remove the advice on adding missing headers: that no longer works. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2013-07-02tools/lguest: real barriers.Rusty Russell
Lguest guests are UP, but the host is probably SMP, so real barriers are required in case the device thread and the guest are on different CPUs. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2013-07-02tools/lguest: fix missing rmb().Rusty Russell
The virtio spec was missing a barrier in example code, so I went back to look at the lguest code. Indeed, we need one. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2013-03-07lguest: fix paths in commentsWanlong Gao
After commit 07fe997, lguest tool has already moved from Documentation/virtual/lguest/ to tools/lguest/. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2013-01-11tools/lguest: remove depends on CONFIG_EXPERIMENTALKees Cook
The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

2012-10-22lguest: fix block request handling in example launcher.Rusty Russell
virtio requests are scatter-gather-style descriptors, but no assumptions should be made about the layout. lguest was lazy here, but saved by the fact that the network device hands all requests to tun (which does it correctly) and console and random devices simply use readv and writev. Block devices, however, are broken: we convert to iovecs internally, just make sure we handle the correctly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-10-04lguest: fix occasional crash in example launcher.Rusty Russell
We usually got away with ->next on the final entry being NULL, but it finally bit me. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: stable@kernel.org
2012-01-12lguest: move the lguest tool to the tools directoryDavidlohr Bueso
This is a better location instead of having it in Documentation. Signed-off-by: Davidlohr Bueso <dave@gnu.org> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (fixed compile)
