* Address feedback
* Tackle #4929 a different way
This turns c.sealed into an atomic, which allows us to call sealInternal
without a lock. By doing so we can better control lock grabbing when a
condition causing the standby loop to get out of active happens. This
encapsulates that logic into two distinct pieces (although they could
be combined into one), and makes lock guarding more understandable.
* Re-add context canceling to the non-HA version of sealInternal
* Return explicitly after stopCh triggered
1) In backends, ensure they are now using TokenPolicies
2) Don't reassign auth.Policies until after expmgr registration as we
don't need them at that point
Fixes#4829
It's not obvious why this should be secret, and if it were considered
secret, when and what anything would ever be allowed to access it.
Likely the right way to tie secret values to particular
entities/aliases/groups would be to use the upcoming templated ACL
feature.
1) Disable MaxRetries in test cluster clients. We generally want to fail
as fast as possible in tests so adding unpredictable timing in doesn't
help things, especially if we're timing sensitive in the test.
2) EquivalentPolicies is supposed to return true if only one set
contains `default` and the other is empty, but if one set was nil
instead of simply a zero length slice it would always return false. This
means that renewing against, say, `userpass` when not actually
specifying any user policies would always fail.
* Add description flag to secrets and auth tune subcommands
* Allow empty description to be provided in secret and auth mount tune
* Use flagNameDescription
This change makes it so that if a lease is revoked through user action,
we set the expiration time to now and update pending, just as we do with
tokens. This allows the normal retry logic to apply in these cases as
well, instead of just erroring out immediately. The idea being that once
you tell Vault to revoke something it should keep doing its darndest to
actually make that happen.
* Allow max request size to be user-specified
This turned out to be way more impactful than I'd expected because I
felt like the right granularity was per-listener, since an org may want
to treat external clients differently from internal clients. It's pretty
straightforward though.
This also introduces actually using request contexts for values, which
so far we have not done (using our own logical.Request struct instead),
but this allows non-logical methods to still get this benefit.
* Switch to ioutil.ReadAll()
* Add an idle timeout for the server
Because tidy operations can be long-running, this also changes all tidy
operations to behave the same operationally (kick off the process, get a
warning back, log errors to server log) and makes them all run in a
goroutine.
This could mean a sort of hard stop if Vault gets sealed because the
function won't have the read lock. This should generally be okay
(running tidy again should pick back up where it left off), but future
work could use cleanup funcs to trigger the functions to stop.
* Fix up tidy test
* Add deadline to cluster connections and an idle timeout to the cluster server, plus add readheader/read timeout to api server
If we have a panic defer functions are run but unlocks aren't. Since we
can't really trust plugins and storage, this backs out the changes for
those parts of the request path.
* This changes the way policies are reported in audit logs.
Previously, only policies tied to tokens would be reported. This could
make it difficult to perform after-the-fact analysis based on both the
initial response entry and further requests. Now, the full set of
applicable policies from both the token and any derived policies from
Identity are reported.
To keep things consistent, token authentications now also return the
full set of policies in api.Secret.Auth responses, so this both makes it
easier for users to understand their actual full set, and it matches
what the audit logs now report.
* Remove a lot of deferred functions in the request path.
There is an interesting benchmark at https://www.reddit.com/r/golang/comments/3h21nk/simple_micro_benchmark_to_measure_the_overhead_of/
It shows that defer actually adds quite a lot of overhead -- maybe 100ns
per call but we defer a *lot* of functions in the request path. So this
removes some of the ones in request handling, ha, barrier, router, and
physical cache.
One meta-note: nearly every metrics function is in a defer which means
every metrics call we add could add a non-trivial amount of time, e.g.
for every 10 extra metrics statements we add 1ms to a request. I don't
know how to solve this right now without doing what I did in some of
these cases and putting that call into a simple function call that then
goes before each return.
* Simplify barrier defer cleanup
* Store lease times suitable for export in pending
This essentially caches lease information for token lookups, preventing
going to disk over and over.
* Simplify logic
Taking inspiration from
https://github.com/golang/go/issues/17604#issuecomment-256384471
suggests that taking the address of a stack variable for use in atomics
works (at least, the race detector doesn't complain) but is doing it
wrong.
The only other change is a change in Leader() detecting if HA is enabled
to fast-path out. This value never changes after NewCore, so we don't
need to grab the read lock to check it.
