stub out security
further wip
Last stub before CRUD for roles
Complete role merging
start tests
add Godep for golang.org/x/crypto/bcrypt
first round of comments
add tests, remove root addition (will be added back as part of creation)
Add security checks for /v2/machines and /v2/keys
Allow non-root to determine if security is enabled, get machine list.
Responding to comments, remove multiple verbs (like /v2/security/user/foo/password)
add some prefixes to the logging
etcd does not provide enough flexibility to configure server SSL and
client authentication separately. When configuring server SSL the
`--ca-file` flag is required to trust self-signed SSL certificates
used to service client requests.
The `--ca-file` has the side effect of enabling client cert
authentication. This can be surprising for those looking to simply
secure communication between an etcd server and client.
Resolve this issue by introducing four new flags:
--client-cert-auth
--peer-client-cert-auth
--trusted-ca-file
--peer-trusted-ca-file
These new flags will allow etcd to support a more explicit SSL
configuration for both etcd clients and peers.
Example usage:
Start etcd with server SSL and no client cert authentication:
etcd -name etcd0 \
--advertise-client-urls https://etcd0.example.com:2379 \
--cert-file etcd0.example.com.crt \
--key-file etcd0.example.com.key \
--trusted-ca-file ca.crt
Start etcd with server SSL and enable client cert authentication:
etcd -name etcd0 \
--advertise-client-urls https://etcd0.example.com:2379 \
--cert-file etcd0.example.com.crt \
--key-file etcd0.example.com.key \
--trusted-ca-file ca.crt \
--client-cert-auth
Start etcd with server SSL and client cert authentication for both
peer and client endpoints:
etcd -name etcd0 \
--advertise-client-urls https://etcd0.example.com:2379 \
--cert-file etcd0.example.com.crt \
--key-file etcd0.example.com.key \
--trusted-ca-file ca.crt \
--client-cert-auth \
--peer-cert-file etcd0.example.com.crt \
--peer-key-file etcd0.example.com.key \
--peer-trusted-ca-file ca.crt \
--peer-client-cert-auth
This change is backwards compatible with etcd versions 2.0.0+. The
current behavior of the `--ca-file` flag is preserved.
Fixes#2499.
Support IPv6 address for ETCD_ADDR and ETCD_PEER_ADDR
pkg/flags: Support IPv6 address for ETCD_ADDR and ETCD_PEER_ADDR
pkg/flags: tests for IPv6 addr and bind-addr flags
pkg/flags: IPAddressPort.Host: do not enclose IPv6 address in square brackets
pkg/flags: set default bind address to [::] instead of 0.0.0.0
pkg/flags: we don't need fmt any more
also, one minor fix: net.JoinHostPort takes string as a port value
pkg/flags: fix ipv6 tests
pkg/flags: test both IPv4 and IPv6 addresses in TestIPAddressPortString
etcdmain: test: use [::] instead of 0.0.0.0
The messages in channel are outdated, and there is no need to send
them in the future. It also reports unreachable if there are messages
in the channel.
Follower should not reject the append message with a smaller index than its commit
index. Or it will trigger the leader's resending logic, which might have a high cost.
ReleaseLockTo should not release the lock on the WAL
segment that is right before the given index. When
restarting etcd, etcd needs to read from the WAL segment
that has a smaller index than the snapshot index.
The correct behavior is that ReleaseLockTo releases
the locks w is holding so that w only holds one lock
that has an index smaller than the given index.
If the TLS config is empty, etcd downgrades https to http without a warning.
This commit avoid the downgrade and stoping etcd from bootstrap if it cannot
listen on TLS.
