[nbdkit PATCH] iso: Shell-quote an alternative isoprog
Otherwise, a user can do things like "nbdkit iso . prog='date;prog'"
to run unintended commands in addition to their alternative isoprog.
This is not a CVE (since nbdkit isn't running with any more privileges
than the user running those commands themselves), but shows the
frailty of relying on the shell to parse subsidiary commands rather
than exec()ing them directly. This patch also doesn't resolve the
fact that we are als...

On the other hand, allowing: prog='isoprog --parameter' may be
intentional, and I just broke that. Maybe I need to revert this?

Needs some work still, see in particular the commit message
for patch 3.

[PATCH nbdkit] Add ssh plugin using libssh.
This adds a simple plugin using libssh (not libssh2). The intended
use for this is with virt-v2v when sourcing guests from VMware over
SSH.
We've had several years of problems getting our libssh-based driver
into qemu. By putting it into nbdkit instead we can bypass that.
However this also lets us combine ssh access with filters, in
particular the recently written ‘rate’ filter.

[PATCH nbdkit 0/5] server: Add .get_ready callback.
I like this change. I think we were overloading the config_complete
method before to do two different things (complete configuration; do
any allocation/housekeeping necessary before we can start serving).
The only questions in my mind are whether we want this before 1.18,
and whether the name ("get_ready") is a good one.
Rich.
