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 Vivek Goyal (5): virtiofsd: Add notion of unprivileged mode virtiofsd: create lock/pid file in per user cache dir virtiofsd: open /proc/self/fd/ in sandbox=NONE mode virtiofsd: Open lo->source while setting up root in sandbox=NONE mode virtiofsd: Skip setup_capabilities() in sandbox=NONE mode tools/virtiofsd/fuse_virtio.c | 15 ++++++++++++++- tools/virtiofsd/passthrough_ll.c | 29 ++++++++++++++++++++++++++--- 2 files changed, 40 insertions(+), 4 deletions(-) -- 2.25.4
