Adds HUP support for audit log files to close and reopen. This makes it
much easier to deal with normal log rotation methods.
As part of testing this I noticed that HUP and other items that come out
of command/server.go are going to stderr, which is where our normal log
lines go. This isn't so much problematic with our normal output but as
we officially move to supporting other formats this can cause
interleaving issues, so I moved those to stdout instead.
This fixes#1911 but not directly; it doesn't address the cause of the
panic. However, it turns out that this is the correct fix anyways,
because it ensures that the value being logged is RFC3339 format, which
is what the time turns into in JSON but not the normal time string
value, so what we audit log (and HMAC) matches what we are returning.
This makes it easier to understand the expected lifetime without a
lookup call that uses the single use left on the token.
This also adds a couple of safety checks and for JSON uses int, rather
than int64, for the TTL for the wrapped token.
This commit splits ACL policies into more fine-grained capabilities.
This both drastically simplifies the checking code and makes it possible
to support needed workflows that are not possible with the previous
method. It is backwards compatible; policies containing a "policy"
string are simply converted to a set of capabilities matching previous
behavior.
Fixes#724 (and others).
with a new endpoint '/sys/audit-hash', which returns the given input
string hashed with the given audit backend's hash function and salt
(currently, always HMAC-SHA256 and a backend-specific salt).
In the process of adding the HTTP handler, this also removes the custom
HTTP handlers for the other audit endpoints, which were simply
forwarding to the logical system backend. This means that the various
audit functions will now redirect correctly from a standby to master.
(Tests all pass.)
Fixes#784
