* 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
* Add `kv rollback`
Like `kv patch` this is more of a helper than anything else; it provides
a single command to fetch the current version (for CAS), read the
version you want to roll back to, and set it as the new version (using
CAS for safety).
This can be used when errors are happening early on to avoid them being
swallowed by logGate.
This also does a bit of cleanup of format env var checking --
helper/logging internally looks for this so it was totally unnecessary
since moving to hclog.
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.
* Allow vault ssh to accept ssh commands in any ssh compatible format
Previously vault ssh required ssh commands to be in the format
`username@hostname <flags> command`. While this works just fine for human
users this breaks a lot of automation workflows and is not compatible
with the options that the ssh client supports.
Motivation
We currently run ansible which uses vault ssh to connect to hosts.
Ansible generates ssh commands with the format `ssh <flags> -o User=username hostname
command`. While this is a valid ssh command it currently breaks with
vault because vault expects the format to be `username@hostname`. To work
around this we currently use a wrapper script to parse the correct username being set
by ansible and translate this into a vault ssh compatible `username@hostname` format
Changes
* You can now specify arguments in any order that ssh client allows. All
arguments are passed directly to the ssh command and the format isn't
modified in any way.
* The username and port are parsed from the specified ssh command. It
will accept all of the options supported by the ssh command and also
will properly prefer `-p` and `user@` if both options are specified.
* The ssh port is only added from the vault credentials if it hasn't
been specified on the command line
* 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
* remove dev-leased-kv flag, handle non-secret responses in the console
* skip lease tests for now
* use the newer collection api for ember-page-object
* include generic in types that can have a v2
* add tests for generic v2
* isolate kv v2 logic in the secret-engine model and add unit tests
* use lazyCapabilities macro in models
* use expandAttributeMeta and fieldToAttrs everywhere
* add angle bracket component polyfill
* use PageHeader component throughout
This massively simplifies transit locking behavior by pushing some
locking down to the Policy level, and embedding either a local or global
lock in the Policy depending on whether caching is enabled or not.
* 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
* Fix panic due to metadata being nil
* added a nil check
* Added a test
* ensure metadata is never nil
* Remove unnecessary allocation
* revert back to early initialization
