Go 1.13 flipped TLS 1.3 to opt-out instead of opt-in, and its TLS 1.3
support does not allow configuring cipher suites. Simply remove the
affected test; it's not relevant going forward and there's ample
evidence it works properly prior to Go 1.13.
* Handpick cluster cipher suites when they're not user-set
There is an undocumented way for users to choose cluster cipher suites
but for the most part this is to paper over the fact that there are
undesirable suites in TLS 1.2.
If not explicitly set, have the set of cipher suites for the cluster
port come from a hand-picked list; either the allowed TLS 1.3 set (for
forwards compatibility) or the three identical ones for TLS 1.2.
The 1.2 suites have been supported in Go until at least as far back as
Go 1.9 from two years ago. As a result in cases where no specific suites
have been chosen this _ought_ to have no compatibility issues.
Also includes a useful test script.
* Abstract generate-root authentication into the strategy interface
* Generate root strategy ncabatoff (#7700)
* Adapt to new shamir-as-kek reality.
* Don't try to verify the master key when we might still be sealed (in
recovery mode). Instead, verify it in the authenticate methods.
Shamir seals now come in two varieties: legacy and new-style. Legacy
Shamir is automatically converted to new-style when a rekey operation
is performed. All new Vault initializations using Shamir are new-style.
New-style Shamir writes an encrypted master key to storage, just like
AutoUnseal. The stored master key is encrypted using the shared key that
is split via Shamir's algorithm. Thus when unsealing, we take the key
fragments given, combine them into a Key-Encryption-Key, and use that
to decrypt the master key on disk. Then the master key is used to read
the keyring that decrypts the barrier.
* core: add postSealMigration method
The postSealMigration method is called at the end of the postUnseal
method if a seal migration has occurred. This starts a seal rewrap
process in the enterprise version of. It is a no-op in the OSS version.

Seal keys can be rotated. When this happens, the barrier and recovery
keys should be re-encrypted with the new seal key. This change
automatically re-encrypts the barrier and recovery keys with the latest
seal key on the active node during the 'postUnseal' phase.

* Fix a deadlock if a panic happens during request handling
During request handling, if a panic is created, deferred functions are
run but otherwise execution stops. #5889 changed some locks to
non-defers but had the side effect of causing the read lock to not be
released if the request panicked. This fixes that and addresses a few
other potential places where things could go wrong:
1) In sealInitCommon we always now defer a function that unlocks the
read lock if it hasn't been unlocked already
2) In StepDown we defer the RUnlock but we also had two error cases that
were calling it manually. These are unlikely to be hit but if they were
I believe would cause a panic.
* Add panic recovery test
Move audit.LogInput to sdk/logical. Allow the Data values in audited
logical.Request and Response to implement OptMarshaler, in which case
we delegate hashing/serializing responsibility to them. Add new
ClientCertificateSerialNumber audit request field.
SystemView can now be cast to ExtendedSystemView to expose the Auditor
interface, which allows submitting requests and responses to the audit
broker.
Increment a counter whenever a request is received.
The in-memory counter is persisted to counters/requests/YYYY/MM.
When the month wraps around, we reset the in-memory counter to
zero.
Add an endpoint for querying the request counters across all time.
* Add ability to migrate autoseal to autoseal
This adds the ability to migrate from shamir to autoseal, autoseal to
shamir, or autoseal to autoseal, by allowing multiple seal stanzas. A
disabled stanza will be used as the config being migrated from; this can
also be used to provide an unwrap seal on ent over multiple unseals.
A new test is added to ensure that autoseal to autoseal works as
expected.

* Address review feedback
* update memdb but not storage in secondaries
* Wire all the things directly do mergeEntity
* Fix persist behavior
* Address review feedback
* Two things:
* Change how we populate and clear leader UUID. This fixes a case where
if a standby disconnects from an active node and reconnects, without the
active node restarting, the UUID doesn't change so triggers on a new
active node don't get run.
* Add a bunch of test helpers and minor updates to things.
* Add helper for checking if an error is a fatal error
The double-double negative was really confusing, and this pattern is used a few places in Vault. This negates the double negative, making the devx a bit easier to follow.
* Check return value of UnsealWithStoredKeys in sys/init
* Return proper error types when attempting unseal with stored key
Prior to this commit, "nil" could have meant unsupported auto-unseal, a transient error, or success. This updates the function to return the correct error type, signaling to the caller whether they should retry or fail.
* Continuously attempt to unseal if sealed keys are supported
This fixes a bug that occurs on bootstrapping an initial cluster. Given a collection of Vault nodes and an initialized storage backend, they will all go into standby waiting for initialization. After one node is initialized, the other nodes had no mechanism by which they "re-check" to see if unseal keys are present. This adds a goroutine to the server command which continually waits for unseal keys to exist. It exits in the following conditions:
- the node is unsealed
- the node does not support stored keys
- a fatal error occurs (as defined by Vault)
- the server is shutting down
In all other situations, the routine wakes up at the specified interval and attempts to unseal with the stored keys.
The result will still pass gofmtcheck and won't trigger additional
changes if someone isn't using goimports, but it will avoid the
piecemeal imports changes we've been seeing.

* Add context cancel checking to inmem/file
* Fix tests
* Fix tests
* Set default max request duration to basically infinity for this release for BC
* 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
* 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.
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.

* Revert "Return invalid lease on negative TTL"
This reverts commit a39597ecdc23cf7fc69fe003eef9f10d533551d8.
* Extend sleep on tests
A few notes:
* We exert positive control over singletons and they usually need to
perform some (known, validated) writes, so this excludes singletons --
they are simply limited to the end of the mount function as before.
* I'm not sure how to test this _specifically_; I've done some testing
of e.g. sealing vault and unsealing and ensuring that I can write to a
KV mount. I think this is tested by every dev server though, since for a
dev server Vault is inited, the default mounts are mounted, then it's
sealed, then it's unsealed for the user, so it already goes through this
code path. The mere fact that you can write to secret/ on a dev server
means it was successfully set read-write.

If it happens after stopping timers any timers firing before all timers
are stopped will still run the revocation function. With plugin
auto-crash-recovery this could end up instantiating a plugin that could
then try to unwrap a token from a nil token store.
This also plumbs in core so that we can grab a read lock during the
operation and check standby/sealed status before running it (after
grabbing the lock).
