Bumps google.golang.org/grpc from 1.79.1 to 1.83.2.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.83.2

Security

  • server: Reject requests missing both :authority and Host headers with HTTP 400 and status Internal. (grpc/grpc-go#9365)

Release 1.83.1

Security

  • xds/rbac: Fix a bug where nested Principal or Permission rules with :scheme or grpc- prefixed header matchers were not rejected, which could cause DENY rules to fail open. (#9258)
  • xds/rbac: Fix a bug where the host header matcher was not being replaced with :authority in nested Principal or Permission rules. (#9258)
  • xds/rbac: Fix a bug where a header matcher whose name was not lowercase, such as X-Role, matched no header, which could cause DENY rules to fail open. (#9332)
  • xds/rbac: Fix a bug where a :scheme or grpc- prefixed header matcher was accepted when its name was not lowercase. (#9332)
  • xds/rbac: Fix a bug where a Host header matcher was not replaced with :authority. (#9332)

Performance

  • transport: Restrict memory overhead of buffering small data frames. (#9331)

Release 1.83.0

Security

  • server: Stop reading from connections when flooded by HTTP/2 frames to mitigate resource exhaustion. The default value for this limit is 100 frames, excluding DATA and HEADERS, and may be changed by setting environment variable GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT.
  • xds/rbac: Support Metadata and RequestedServerName permissions matcher fields. If present in a DENY rule, previously these would be ignored and fail-open.
  • xds/rbac: Fix panic when parsing unsupported fields in NotRule/NotId permissions.
  • xds/rbac: Support the deprecated source_ip principal identifier by treating it as equivalent to direct_remote_ip.
  • xds: Fix panic when parsing route header matchers configured with empty exact_match, prefix_match, or suffix_match strings. (#9223)

New Features

  • xds/googlec2p: Enable DirectPath over Interconnect support for on-premises clients via the force-xds target URI query parameter. (#9133)
  • xds: Enable xDS configuration to control which fields get propagated from ORCA backend metric reports to LRS load reports. (#9145)
  • authz: Add OnPolicyUpdate callback to FileWatcherOptions to notify when an authz policy is loaded or updated. (#9142)
  • xds: Add support for the GCP Authentication HTTP Filter, which automatically fetches and attaches GCP Service Account Identity JWT tokens to outgoing RPCs.
    • This feature can be enabled by setting environment variable GRPC_EXPERIMENTAL_XDS_GCP_AUTHENTICATION_FILTER=true. (#9119)
  • xds: Add support for xDS-based HTTP CONNECT proxies.
    • This feature can be enabled by setting environment variable GRPC_EXPERIMENTAL_XDS_HTTP_CONNECT=true. (#9151)
  • xds: Add support for contains_match in route header matchers. (#9223)

Bug Fixes

  • credentials/alts: Fix panic when processing malformed frames by validating that the message frame length exceeds the message type field size. (#9197)
  • grpc: Fix compilation on Plan 9 targets (GOOS=plan9), broken since v1.81.0. (#9255)
