allow disabling tcp/quic
In order to have more control of a server so that we can
simulate connection failures in `testplanet`, this PR changes
quic.Listener to accept an existing UDPConn instead of relying on the
quic-go library to create the UDPConn.
This PR also adds two flags on the `server.Config` struct to allow
enabling/disabling tcp/tls listener and quic listener. By default, they
are both set to true.
- `DisableTCPTLS`: internal flag, disables tcp/tls listener.
- `DisableQUIC`: hidden flag, disables quic listener
By making the `DisableQUIC` a hidden flag, it allows storagenode operators to
have the ability to disable quic traffic in case their set up can't work

It's impossible to time correctly this check. The segment may expire
just at the time we upload the repaired pieces to new storage nodes.
They will reject this as expired and the repair will fail.
Also, we penalize storage nodes with audit failure only if they fail
piece hash verification, i.e. return incorrect data, but only if they
have already deleted the piece.
So, it would be best if the repair service does not care about object
expiration at all. This is a responsibility of another service.
Removing this check will also simplify how we migrate this code
correctly to the metabase.

This is the first step in the removal of uptime columns on the

uptime_success_count
total_uptime_count
uptime_reputation_alpha
uptime_reputation_beta
In order to avoid breaking backwards compatibility, we need to
remove all references to these columns before removing the columns
themselves from the database. However, since uptime_success_count
and total_uptime_count are NOT NULLABLE, we can't remove them from
the insert statements in the overlay. So we can't remove the columns
because of the references, and we can't remove the references because
the columns can't be null. What a pickle. To remedy this, we will set a
default on the columns. Then we should be able to remove them from the
insert statements

We have to adapt the live accounting to allow the packages that use it
to differentiate about errors for being able to ignore them and make our
satellite resilient to Redis downtime.
For differentiating errors we should make changes in the live accounting
but also in the storage/redis.Client, however, we may need to do some
dirty workarounds or break other parts of the implementation that
depends on it.
On the other hand we want to get rid of the storage/redis.Client because
it has more functionality that the one that we are using and some
process has been started to remove it.
Hence, we have refactored the live accounting to directly use the Redis
client library for later on (in a future commit) adapt the satellite for
being resilient to Redis downtime.

The chief segment health models we've come up with are the "immediate
danger" model and the "survivability" model. The former calculates the
chance of losing a segment becoming lost in the next time period (using
the CDF of the binomial distribution to estimate the chance of x nodes
failing in that period), while the latter estimates the number of
iterations for which a segment can be expected to survive (using the
mean of the negative binomial distribution). The immediate danger model
was a promising one for comparing segment health across segments with
different RS parameters, as it is more precisely what we want to
prevent, but it turns out that practically all segments in production
have infinite health, as the chance of losing segments with any
reasonable estimate of node failure rate is smaller than DBL_EPSILON,
the smallest possible difference from 1.0 representable in a float64
(about 1e-16).
Leaving aside the wisdom of worrying about the repair of segments that
have less than a 1e-16 chance of being lost, we want to be extremely
conservative and proactive in our repair efforts, and the health of the
segments we have been repairing thus far also evaluates to infinity
under the immediate danger model. Thus, we find ourselves reaching for
an alternative.
Dr. Ben saves the day: the survivability model is a reasonably close
approximation of the immediate danger model, and even better, it is
far simpler to calculate and yields manageable values for real-world
segments. The downside to it is that it requires as input an estimate
of the total number of active nodes.
This change replaces the segment health calculation to use the
survivability model, and reinstates the call to SegmentHealth() where it
was reverted. It gets estimates for the total number of active nodes by
leveraging the reliability cache.

A few weeks ago it was discovered that the segment health function
was not working as expected with production values. As a bandaid,
we decided to insert the number of healthy pieces into the segment
health column. This should have effectively reverted our means of
prioritizing repair to the previous implementation.
However, it turns out that the bandaid was placed into the code which
removes items from the irreparable db and inserts them into the repair
queue.
This change: insert number of healthy pieces into the repair queue in the
method, RemoteSegment

There is a new checker field called statsCollector. This contains
a map of stats pointers where the key is a stringified redundancy
scheme. stats contains all tagged monkit metrics. These metrics exist
under the key name, "tagged_repair_stats", which is tagged with the
name of each metric and a corresponding rs scheme.
As the metainfo observer works on a segment, it checks statsCollector
for a stats corresponding to the segment's redundancy scheme. If one
doesn't exist, it is created and chained to the monkit scope. Now we can call
Observe, Inc, etc on the fields just like before, and they have tags!
durabilityStats has also been renamed to aggregateStats.
At the end of the metainfo loop, we insert the aggregateStats totals into the
corresponding stats fields for metric reporting.

We migrated satelliteDB off of Postgres and over to CockroachDB (crdb), but there was way too high contention for the injuredsegments table so we had to rollback to Postgres for the repair queue. A couple things contributed to this problem:
1) crdb doesn't support `FOR UPDATE SKIP LOCKED`
2) the original crdb Select query was doing 2 full table scans and not using any indexes
3) the SLC Satellite (where we were doing the migration) was running 48 repair worker processes, each of which run up to 5 goroutines which all are trying to select out of the repair queue and this was causing a ton of contention.
The changes in this PR should help to reduce that contention and improve performance on CRDB.
The changes include:
1) Use an update/set query instead of select/update to capitalize on the new `UPDATE` implicit row locking ability in CRDB.
- Details: As of CRDB v20.2.2, there is implicit row locking with update/set queries (contention reduction and performance gains are described in this blog post: https://www.cockroachlabs.com/blog/when-and-why-to-use-select-for-update-in-cockroachdb/).
2) Remove the `ORDER BY` clause since this was causing a full table scan and also prevented the use of the row locking capability.
- While long term it is very important to `ORDER BY segment_health`, the change here is only suppose to be a temporary bandaid to get us migrated over to CRDB quickly. Since segment_health has been set to infinity for some time now (re: https://review.dev.storj.io/c/storj/storj/+/3224), it seems like it might be ok to continue not making use of this for the short term. However, long term this needs to be fixed with a redesign of the repair workers, possible in the trusted delegated repair design (https://review.dev.storj.io/c/storj/storj/+/2602) or something similar to what is recommended here on how to implement a queue on CRDB https://dev.to/ajwerner/quick-and-easy-exactly-once-distributed-work-queues-using-serializable-transactions-jdp, or migrate to rabbit MQ priority queue or something similar..
This PRs improved query uses the index to avoid full scans and also locks the row its going to update and CRDB retries for us if there are any lock errors.

We want to stop using the serial_numbers table in satelliteDB. One of the last places using the serial_numbers table is when storagenodes settle orders, we look up the bucket name and project ID from the serial number from the serial_numbers table.
Now that we have support to add encrypted metadata into the OrderLimit, this PR makes use of that and now attempts to read the project ID and bucket name from the encrypted orderLimit metadata instead of from the serial_numbers table. For backwards compatibility and to ensure no errors, we will still fallback to the old way of getting that info from the serial_numbers table, but this will be removed in the next release as long as there are no errors.
All processes that create orderLimits must have an orders.encryption-keys set. The services that create orderLimits (and thus need to encrypt the order metadata) are the satellite apiProcess, the repair process, audit service (core process), and graceful exit (core process). Only the satellite api process decrypts the order metadata when storagenodes settle orders. This means that the same encryption key needs to be provided in the config for the satellite api process, repair process, and the core process like so:
orders.include-encrypted-metadata=true
orders.encryption-keys="<"encryptionKeyID>=<encryptionKey>"

We did not test the SegmentHealth function with actual production

result in +Inf segment health - so pretty much all segments put into the

the segments are ordered as they were before. We need to refine the

Firstly, this changes the repair functionality to return Canceled errors
when a repair is canceled during the Get phase. Previously, because we
do not track individual errors per piece, this would just show up as a
failure to download enough pieces to repair the segment, which would
cause the segment to be added to the IrreparableDB, which is entirely
unhelpful.
Then, ignore Canceled errors in the return value of the repair worker.
Apparently, when the worker returns an error, that makes Cobra exit the
program with a nonzero exit code, which causes some piece of our
deployment automation to freak out and page people. And when we ask the
repair worker to shut down, "canceled" errors are what we _expect_, not
an error case.

We plan to add support for a new Reed-Solomon scheme soon, but our
repair queue orders segments by least number of healthy pieces first.
With a second RS scheme, fewer healthy pieces will not necessarily
correlate to lower health.
This change just adds the new column in a migration. A separate change
will add the new health function.
Right now, since we only support one RS scheme, behavior will not
change. Number of healthy pieces is being inserted as "segment health"
until the new health function is merged.
Segment health is calculated with a new priority function created in
commit 3e5640359. In order to use the function, a new config value is
added, called NodeFailureRate, representing the approximate probability
of any individual node going down in the duration of one checker run.

Storage nodes undergoing Graceful Exit have up to now been receiving

transferring pieces. This adds up to a lot of DNS lookups, which
apparently overwhelm some home routers. There does not seem to be any

The nodes fell into a few categories:
1. Always fail to list orders from the db; never get to try sending orders from the filestore
2. Successfully list/send orders from the db; never get to calling satellite endpoint for submitting filestore orders
3. Successfully list/send orders from the db; successfully list filestore orders, but satellite endpoint fails (with "unauthenticated" drpc error)
The code change here add the following to address these issues:
- modify the query for ordersDB.listUnsentBySatellite so that we no longer select expired orders from the unsent_orders table
- always process any orders that are in the ordersDB and also any orders stored in the filestore
- add monkit monitoring to filestore.ListUnsentBySatellite so that we can see the failures/successes

This preserves the last_ip_and_port field from node lookups through
CreateAuditOrderLimits() and CreateAuditOrderLimit(), so that later
calls to (*Verifier).GetShare() can try to use that IP and port. If a
connection to the given IP and port cannot be made, or the connection
cannot be verified and secured with the target node identity, an
attempt is made to connect to the original node address instead.
A similar change is not necessary to the other Create*OrderLimits
functions, because they already replace node addresses with the cached
IP and port as appropriate. We might want to consider making a similar
change to CreateGetRepairOrderLimits(), though.
The audit situation is unique because the ramifications are especially
powerful when we get the address wrong. Failing a single audit can have
a heavy cost to a storage node. We need to make extra effort in order
to avoid imposing that cost unfairly.
Situation 1: If an audit fails because the repair worker failed to make
a DNS query (which might well be the fault on the satellite side), and
we have last_ip_and_port information available for the target node, it
would be unfair not to try connecting to that last_ip_and_port address.
Situation 2: If a node has changed addresses recently and the operator
correctly changed its DNS entry, but we don't bother querying DNS, it
would be unfair to penalize the node for our failure to connect to it.
So the audit worker must try both last_ip_and_port _and_ the node
address as supplied by the SNO.
We elect here to try last_ip_and_port first, on the grounds that (a) it
is expected to work in the large majority of cases, and (b) there
should not be any security concerns with connecting to an out-or-date
address, and (c) avoiding DNS queries on the satellite side helps
alleviate satellite operational load.

This change allows the creation and deletion of api keys via the admin API.
It adds two methods for deletion, one via the name and projectID and the
second one via the serialized apikey directly.

We are moving an error into rejectErr since its preventing storage nodes from being able to settle other orders.

Use tagsql.DB pointer as step database, to propagate changes
back and forth between actual database and migration.
Adds CreateDB operation to the migration step to be able to
create new dbs before executing migration action.
Adjusts storagenode database migration to use inner tagsql.DB
pointer of each database as step.DB.
Adjusts satellite dabase migration, adds proxy migrationDB field
to satellite db that wraps itself as tagsql.DB, pointer of which
is used as step.DB.

This change completes the column migration of
5f6fccc6e8 and
2f648fd981.
It resets every users project limits who are below or equal to our
current production defaults.

WHAT:
Now project amount limit is taken from users db instead of config. But if db value is 0 then default config value will be used instead.
WHY:
this will allow us to change user's project limit by changing db value.

This makes it possible to remove of this obsolete flag from the
multi-tenant gateway.
As a consequence, displaying the GATEWAY_0_ACCESS env var will always
require a running storj-sim. Until now, it was required only the first
time. Then the value was stored in the 'access' config. But this is now
not possible anymore.
The changes in StripeMock are required to fix failures in integration
tests. StripeMock is in-memory and its data does not survive restarts of
storj-sim. The second and following starts of storj-sim had invalid
state of StripeMock, which failed requests that were required to
populate the GATEWAY_0_ACCESS env var. The changes in StripeMock makes
it repopulate the Stripe customers from the database.
