# Overview
|
|
|
|
This page contains the list of deprecations and important or breaking changes
|
|
for Vault 1.2.0 compared to 1.1.0. Please read it carefully.
|
|
|
|
## Known Issues
|
|
|
|
### AppRole Upgrade Issue
|
|
|
|
Due to a bug, on upgrade AppRole roles cannot be read properly. If using AppRole, do not upgrade until this issue is fixed in 1.2.1.
|
|
|
|
## Changes/Deprecations
|
|
|
|
### Path Character Handling
|
|
|
|
Due to underlying changes in Go's runtime past version 1.11.5, Vault is now
|
|
stricter about what characters it will accept in path names. Whereas before it
|
|
would filter out unprintable characters (and this could be turned off), control
|
|
characters and other invalid characters are now rejected within Go's HTTP
|
|
library before the request is passed to Vault, and this cannot be disabled. To
|
|
continue using these (e.g. for already-written paths), they must be properly
|
|
percent-encoded (e.g. `\r` becomes `%0D`, `\x00` becomes `%00`, and so on).
|
|
|
|
### AWSKMS Seal Region
|
|
|
|
The user-configured regions on the AWSKMS seal stanza will now be preferred
|
|
over regions set in the enclosing environment.
|
|
|
|
### Audit Logging of Empty Values
|
|
|
|
All values in audit logs now are omitted if they are empty. This helps reduce
|
|
the size of audit log entries by not reproducing keys in each entry that
|
|
commonly don't contain any value, which can help in cases where audit log
|
|
entries are above the maximum UDP packet size and others.
|
|
|
|
### Rollback Logging
|
|
|
|
Rollback will no longer display log messages when it runs; it will only display
|
|
messages if an error occurs.
|
|
|
|
### Database Plugins
|
|
|
|
Database plugins now default to 4 max open connections rather than 2. This
|
|
should be safe in nearly all cases and fixes some issues where a single
|
|
operation could fail with the default configuration because it needed three
|
|
connections just for that operation. However, this could result in an increase
|
|
in held open file descriptors for each database configuration, so ensure that
|
|
there is sufficient overhead.
|
|
|
|
### AppRole Various Changes
|
|
|
|
- AppRole uses new, common token fields for values that overlap with other auth
|
|
methods. `period` and `policies` will continue to work, with priority being
|
|
given to the `token_` prefixed versions of these fields, but the values for
|
|
those will only be returned on read if they were set initially.
|
|
- `default` is no longer automatically added to policies after submission. It
|
|
was a no-op anyways since Vault's core would always add it, and changing this
|
|
behavior allows AppRole to support the new `token_no_default_policy`
|
|
parameter
|
|
- The long-deprecated `bound_cidr_list` is no longer returned when reading a
|
|
role.
|
|
|
|
### Token Store Roles Changes
|
|
|
|
Token store roles use new, common token fields for the values that overlap with
|
|
other auth backends. `period`, `explicit_max_ttl`, and `bound_cidrs` will
|
|
continue to work, with priority being given to the `token_` prefixed versions
|
|
of those parameters. They will also be returned when doing a read on the role
|
|
if they were used to provide values initially; however, in Vault 1.4 if
|
|
`period` or `explicit_max_ttl` is zero they will no longer be returned.
|
|
(`explicit_max_ttl` was already not returned if empty.)
|
|
|
|
### Go API/SDK Changes
|
|
|
|
Vault now uses Go's official dependency management system, Go Modules, to
|
|
manage dependencies. As a result to both reduce transitive dependencies for API
|
|
library users and plugin authors, and to work around various conflicts, we have
|
|
moved various helpers around, mostly under an `sdk/` submodule. A couple of
|
|
functions have also moved from plugin helper code to the `api/` submodule. If
|
|
you are a plugin author, take a look at some of our official plugins and the
|
|
paths they are importing for guidance.
|
|
|
|
### Change in LDAP Group CN handling
|
|
|
|
A bug fix put in place in Vault 1.1.1 to allow group CNs to be found from an
|
|
LDAP server in lowercase `cn` as well as uppercase `CN` had an unintended
|
|
consequence. If prior to that a group used `cn`, as in `cn=foo,ou=bar` then the
|
|
group that would need to be put into place in the LDAP plugin to match against
|
|
policies is `cn=foo,ou=bar` since the CN would not be correctly found. After
|
|
the change, the CN was correctly found, but this would result in the group name
|
|
being parsed as `foo` and would not match groups using the full DN. In 1.1.5+,
|
|
there is a boolean config setting `use_pre111_group_cn_behavior` to allow
|
|
reverting to the old matching behavior; we also attempt to upgrade exiting
|
|
configs to have that defaulted to true.
|
|
|
|
### JWT/OIDC Plugin
|
|
|
|
Logins of role_type "oidc" via the /login path are no longer allowed.
|
|
|
|
### ACL Wildcards
|
|
|
|
New ordering put into place in Vault 1.1.1 defines which policy wins when there
|
|
are multiple inexact matches and at least one path contains `+`. `+*` is now
|
|
illegal in policy paths. The previous behavior simply selected any matching
|
|
segment-wildcard path that matched.
|
|
|
|
### Replication
|
|
|
|
Due to technical limitations, mounting and unmounting was not previously
|
|
possible from a performance secondary. These have been resolved, and these
|
|
operations may now be run from a performance secondary.
