Hi,
This is V2 of patches. Only change since last version is handling of
lock/pid file creation as per the comments from Daniel Berrange.
I can't think of any more changes needed. As a unpriviliged user
inside VM I can do simple operations like create/remove/read/write
files.
For more testing, I probably need a testsuite which runs as unpriviliged
user. pjdfstests needs to run as root and this does not work in this
setup as creation of files as root fails. (On host, daemon tries to
switch to root uid and that fails).
So as of now, I think these are the minimum changes needed to support
unprivileged passthrough mode of virtiofsd.
Thanks
Vivek
