* Fix various read only storage errors
A mistake we've seen multiple times in our own plugins and that we've
seen in the GCP plugin now is that control flow (how the code is
structured, helper functions, etc.) can obfuscate whether an error came
from storage or some other Vault-core location (in which case likely it
needs to be a 5XX message) or because of user input (thus 4XX). Error
handling for functions therefore often ends up always treating errors as
either user related or internal.
When the error is logical.ErrReadOnly this means that treating errors as
user errors skips the check that triggers forwarding, instead returning
a read only view error to the user.
While it's obviously more correct to fix that code, it's not always
immediately apparent to reviewers or fixers what the issue is and fixing
it when it's found both requires someone to hit the problem and report
it (thus exposing bugs to users) and selective targeted refactoring that
only helps that one specific case.
If instead we check whether the logical.Response is an error and, if so,
whether it contains the error value, we work around this in all of these
cases automatically. It feels hacky since it's a coding mistake, but
it's one we've made too multiple times, and avoiding bugs altogether is
better for our users.
* Fix a locking issue in the Rollback manager
* Update rollback.go
* Update rollback.go
* move state creation
* Update vault/rollback.go
Co-Authored-By: briankassouf <briankassouf@users.noreply.github.com>
* Simplify logic by canceling the lock grab
* Use context instead of a chan
* Update vault/rollback.go
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 request timeouts in normal request path and to expirations
* Add ability to adjust default max request duration
* Some test fixes
* Ensure tests have defaults set for max request duration
* 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
* logbridge with hclog and identical output
* Initial search & replace
This compiles, but there is a fair amount of TODO
and commented out code, especially around the
plugin logclient/logserver code.

The rollback manager was using a saved MountTable rather than the
current table, causing it to attempt to rollback unmounted mounts, and
never rollback new mounts.
In fixing this, it became clear that bad things could happen to the
mount table...the table itself could be locked, but the table pointer
(which is what the rollback manager needs) could be modified at any time
without locking. This commit therefore also returns locking to a mutex
outside the table instead of inside, and plumbs RLock/RUnlock through to
the various places that are reading the table but not holding a write
lock.
Both unit tests and race detection pass.
Fixes#771
