vhost: correctly set bits of dirty pages

2010-11-29T08:26:55+00:00

Fix two bugs in dirty page logging:
When counting pages we should increase address by 1 instead of
VHOST_PAGE_SIZE. Make log_write() correctly process requests
that cross pages with write_address not starting at page boundary.

vhost: max s/g to match qemu

2010-10-05T11:33:43+00:00

Qemu supports up to UIO_MAXIOV s/g so we have to match that because guest
drivers may rely on this.

Allocate indirect and log arrays dynamically to avoid using too much contigious
memory and make the length of hdr array to match the header length since each
iovec entry has a least one byte.

Test with copying large files w/ and w/o migration in both linux and windows
guests.

vhost: fix log ctx signalling

2010-09-22T14:21:33+00:00

The log eventfd signalling got put in dead code.
We didn't notice because qemu currently does polling
instead of eventfd select.

vhost: error handling fix

vhost should set worker to NULL on cgroups attach failure,
so that we won't try to destroy the worker again on close.

vhost: fix attach to cgroups regression

2010-09-06T06:49:31+00:00

Since 2.6.36-rc1, non-root users of vhost-net fail to attach
if they are in any cgroups.

The reason is that when qemu uses vhost, vhost wants to attach
its thread to all cgroups that qemu has.  But we got the API backwards,
so a non-priveledged process (Qemu) tried to control
the priveledged one (vhost), which fails.

Fix this by switching to the new cgroup_attach_task_all,
and running it from the vhost thread.
