Linux network stats (#44)
* Add libnl-3 and libnl-route-3 dependency if Linux (libnl-3-dev on ubuntu)
* Add libnl-3 flags, refactor stats/dune

Use dune-configurtator to get C flags. In the dune-configurator script,
we detect whether we're running on Linux or FreeBSD.

Ergonomics (#41)
The info subcommands for {unikernel,block,policy} never error

Before, running the commands block, info or policy when no block
devices, unikernels or policies respectively were set up the command
would report an error and give the user a dangerous-looking WARNING
saying the command failed:

    $ albatross-client-local block
    albatross-client-local: [WARNING] host [vm: ]: command failed block: not found

Now instead the commands will report success with a message stating
there are no objects.

Hannes Mehnert 125711ac6d further rng cleanups (remove deps from dune); albatross-client-inspect-dump which reads a state file (for cautious upgrades) 2020-07-05 20:39:29 +02:00
Hannes Mehnert d93a683d94 tls: no need to initialize rng (tls.lwt does this for us) 2020-06-23 20:03:59 +02:00
Hannes Mehnert c98ac0494d retry-connections now defaults to 0
this makes it much easier to reason about the initialization.

for production, init scripts should enforce the dependency order
for testing, provide your own if desired

Hannes Mehnert 18728a7601 packaging/linux: cleanups of systemd scripts
- console creates the run directories (albatross albatross/fifo albatross/util)
-> log depends on console
- albatross/fifo needs special permission (albatross_daemon creates fifo there, albatross_console needs to read them)
- use /var/lib/albatross/albatross.log for the log file
- only require root in albatross_daemon, use user albatross in albatross_console and albatross_log
- defer albatross_stat for now

Hannes Mehnert 14f861b945 stats: instead of executing the sysctl kinfo_proc twice (for retrieving kinfo_mem and rusage), only execute it once 2020-03-31 11:53:07 +02:00
Hannes Mehnert 65693ea188 revise the "--net=yyy" argument to (optionally) contain a service:bridge
it used to only contain service, and used the same string for the bridge. This
is not flexible enough to run off-the-shelf unikernels (configured for bridge
"service" and "management" on multi-homed servers). The old behaviour is the
new default (i.e. "--net=service" creates and attaches a tap device to bridge
"service", and passes "--net:service=tapYY" to the solo5 tender). But it is more
flexible now: "--net=service:other-bridge" will create a tap device attached to
"other-bridge" and pass "--net:service=tapYY" to the tender. This way, there's
no need to match bridge names on the actual server with network device names of
the unikernels.

NB: this is (mostly) backwards-compatible: the on-disk data structures are
versioned (and the version is bumped with this PR), an old albatross client can
send "create" commands to a new server. But a new client will get a parse error
from an old server - which is fine taking into consideration the deployment
base.
