Release Notes

grpc/grpc-java (io.grpc:grpc-okhttp)

v1.68.3

Bug Fixes

• okhttp: Improve certificate handling by rejecting non-ASCII subject alternative names and hostnames as seen in CVE-2021-0341 (#​11749) (a0982ca). Hostnames are considered trusted and CAs are required to use punycode for non-ASCII hostnames, so this is expected to provide defense-in-depth. See also the related GoSecure blog post and the AOSP fix
• xds: Preserve nonce when unsubscribing last watcher of a particular type so that new discovery requests of that type are handled correctly (1cf1927). This (along with 6c12c2b) fixes a nonce-handling regression introduced in 1.66.0 that could cause resources to appear to not exist until re-creating the ADS stream. Triggering the behavior required specific config changes. It is easiest to trigger when clusters use EDS and routes are changed from one cluster to another. The error “found 0 leaf (logical DNS or EDS) clusters for root cluster” might then be seen
• xds: Remember nonces for unknown types (6c12c2b)
• xds: Unexpected types in the bootstrap’s server_features should be ignored (e8ff6da). They were previously required to be strings
• xds: Fixed unsupported unsigned 32 bits issue for circuit breaker (#​11735) (f8f6139). This fixes clients treating large max_requests as “no requests” and failing all requests

v1.68.2

Bug Fixes

• api: When forwarding from Listener onAddresses to Listener2 continue to use onResult (#​11688). This fixes a 1.68.1 "IllegalStateException: Not called from the SynchronizationContext" regression (#​11662) that could be seen in certain custom NameResolvers
• okhttp: If the frame handler thread is null do not schedule it on the executor (#​11716). This fixes a 1.68.1 NullPointerException regression when a custom transportExecutor was provided to the channel and it did not have enough threads to run new tasks

Improvements

• examples: Use xds-enabled server and xds credentials in example-gcp-csm-observability (#​11707)

v1.68.1

v1.68.0 was a mistake. This is the first release of version 1.68.x

Bug Fixes

• xds: Fix NullPointerException introduced in "Fix load reporting when pick first is used for locality-routing" (#​11553). This fix was in 1.67.1 but not 1.68.0

Behavior Changes

• core: JSON parsing rejects duplicate keys in objects (#​11575) (4be69e3). This is the existing behavior in C core. Duplicate keys in objects are dangerous as which value takes effect is undefined. Previously, the last value was used
• okhttp: Detect transport executors with no remaining threads (#​11503) (3a6be9c). The transport uses two threads, but one is on-demand. If the executor provided to builder.transportExecutor() runs out of threads (e.g., it is a fixed-size thread pool), all transports can be wedged, unable to run on-demand tasks, until keepalive kills one of them. Two threads are now used when handshaking a new transport, and the transport will time out after 1 second with “Timed out waiting for second handshake thread” if two threads are unavailable
• gcp-csm-o11y: Get mesh_id value from CSM_MESH_ID environment variable, instead of getting it from bootstrap file (84d30af)

Improvements

• New grpc-context-override-opentelemetry artifact (#​11523) (782a44a) (#​11599) (e59ae5f). This is a io.grpc.Context storage override to store its state in io.opentelemetry.context.Context. Libraries should not add a dependency on this artifact, as applications can only have one storage override in their classpath
• New grpc-s2a artifact. It is a transport that offloads the handshake similar to ALTS, but for TLS. It provides io.grpc.s2a.S2AChannelCredentials
• api: Enhance name resolver `ResolutionResult` to hold addresses or error so the single listener API onResult2 is used to convey both success and error cases for name resolution (#​11330) (1ded8af)
• core: Handle NameResolver/LoadBalancer exceptions when panicking (b692b9d). This expands the class of bugs that will fail RPCs with the panic error, versus some undefined behavior
• core: Use the default service config in case of initial name resolver address resolution error (#​11577) (fa26a8b)
• core: StreamTracer.inboundMessageRead() now reports uncompressed message size when the message does not need compression (#​11598) (2aae68e). Previously it always reported -1 (unknown)
• netty: Avoid TCP_USER_TIMEOUT warning when explicitly specifying a non-epoll channel type to use (#​11564) (62f4098)
• okhttp: Don't warn about missing Conscrypt (6f35422). This is especially helpful when using TLS but not running on Android
• android: For UdsChannelBuilder, use fake IP instead of localhost (a908b5e). This avoids an unnecessary DNS lookup
• xds: Add xDS node ID in select control plane errors to enable cross-referencing with control plane logs when debugging (f3cf7c3)
• xds: Enhanced how ADS stream terminations are handled, specifically addressing cases where a response has or hasn't been received (#​2e9c3e19f)
• binder: Update status code documentation for Android 11's package visibility rules. (#​11551) (99be6e9)
• binder: Update binderDied() error description to spell out the possibilities for those unfamiliar with Android internals. (#​11628) (46c1b38)
• example-gauth: Use application default creds instead of file argument (#​11595) (94a0a0d)
• opentelemetry: Experimental OpenTelemetry tracing is available. Set the GRPC_EXPERIMENTAL_ENABLE_OTEL_TRACING environment variable to true to enable tracing support in GrpcOpenTelemetry (#​11409, #​11477)(043ba55, 421e237)

Dependencies

• Updated protobuf-java to 3.25.5. This helps avoid CVE-2024-7254 (2ff837a)
