Currently the user can't list only the keys in a prefix search. In
order to support such operations the filtering will be done on the
server side to reduce the encoding and network transfer costs.
This commit expands RPCs for getting user and role and support list up
all users and roles. etcdctl v3 is now support getting all users and
roles with the newly added option --all e.g. etcdctl user get --all
Currently auth tokens are generated in the replicated state machine
layer randomly. It means one auth token generated in node A cannot be
used for node B. It is problematic for load balancing and fail
over. This commit moves the token generation logic from the state
machine to API layer (before raft) and let all nodes share a single
token.
Log index of Raft is also added to a token for ensuring uniqueness of
the token and detecting activation of the token in the cluster (some
nodes can receive the token before generating and installing the token
in its state machine).
This commit also lets authStore have simple token related things. It
is required because of unit test. The test requires cleaning of the
state of the simple token things after one test (succeeding test can
create duplicated token and it causes panic).
This commit adds a feature for granting and revoking range of keys,
not a single key.
Example:
$ ETCDCTL_API=3 bin/etcdctl role grant r1 readwrite k1 k3
Role r1 updated
$ ETCDCTL_API=3 bin/etcdctl role get r1
Role r1
KV Read:
[a, b)
[k1, k3)
[k2, k4)
KV Write:
[a, b)
[k1, k3)
[k2, k4)
$ ETCDCTL_API=3 bin/etcdctl --user u1:p get k1 k4
k1
v1
$ ETCDCTL_API=3 bin/etcdctl --user u1:p get k1 k5
Error: etcdserver: permission denied
This commit implements RoleGet() RPC of etcdserver and adds a new
subcommand "role get" to etcdctl v3. It will list up permissions that
are granted to a given role.
$ ETCDCTL_API=3 bin/etcdctl role get r1
Role r1
KV Read:
b
d
KV Write:
a
c
d
This commit adds a new subcommand "user get" to etcdctl v3. It will
list up roles that are granted to a given user.
Example:
$ ETCDCTL_API=3 bin/etcdctl user get u1
User: u1
Roles: r1 r2 r3
This commit also modifies the layout of InternalRaftRequest for
frequent update of auth related members.
This commit lets etcdserver check permission during its log applying
phase. With this change, permission checking of operations is
supported.
Currently, put and range are supported. In addition, multi key
permission check of range isn't supported yet.
There was a bug in protodoc.
This changes git SHA to use the latest protodoc.
And make the letter casing consistent with original
Protocol Buffer. Go capitalizes the member variables,
but the protocol buffer documentation should be same as
original proto files.
This commit implements Authenticate() API of the auth package. It does
authentication based on its authUsers bucket and generate a token for
succeeding RPCs.
This commit adds a functionality of user deletion. It can be invoked
with the new user delete command.
Example usage:
$ ETCDCTL_API=3 etcdctl user delete usr1
