chore(deps): bump google.golang.org/grpc from 1.81.0 to 1.82.1

[dependabot]

Bumps google.golang.org/grpc from 1.81.0 to 1.82.1.

Release notes

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

Release 1.82.1

Security

• server: Stop reading from the connection when flooded by HTTP/2 frames. 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.

Release 1.82.0

Behavior Changes

• server: Remove support for GRPC_GO_EXPERIMENTAL_DISABLE_STRICT_PATH_CHECKING environment varibale. Strict incoming RPC path validation (which has been the default since v1.79.3) can no longer be disabled. (#9112)
• transport: Add environment variable to change the default max header list size from 16MB to 8KB. This may be enabled by setting GRPC_GO_EXPERIMENTAL_ENABLE_8KB_DEFAULT_HEADER_LIST_SIZE=true. This will be enabled by default in a subsequent release. (#9019)
• balancer: Load Balancing policy registry is now case-sensitive. Set GRPC_GO_EXPERIMENTAL_CASE_SENSITIVE_BALANCER_REGISTRIES=false (and file an issue) to revert to case-insensitive behavior. (#9017)

New Features

• experimental/stats: Expose a new API, NewContextWithLabelCallback, to register a callback that is invoked when telemetry labels are added. (#8877)
  • Special Thanks: @​seth-epps
• client: Return a portion of the response body in the error message, when the client receives an unexpected non-gRPC HTTP response, to make debugging easier. (#8929)
  • Special Thanks: @​chengxilo
• server: Add environment variable GRPC_GO_SERVER_GOROUTINE_LABELS that controls setting runtime/pprof.Labels on goroutines spawned by the server. Set GRPC_GO_SERVER_GOROUTINE_LABELS=grpc.method=true to add the grpc.method label on goroutines spawned to handle incoming requests. (#9082)
  • Special Thanks: @​dfinkel

Bug Fixes

• xds/server: Fix a memory leak of HTTP filter instances occurring when route configurations are updated in-place during a Route Discovery Service (RDS) update. (#9138)
• grpc: In the deprecated gzip Compressor (used via the deprecated WithCompressor dial option), enforce the MaxRecvMsgSize limit on the decompressed message buffer, preventing excessive memory allocation from highly compressed payloads. (#9114)
  • Special Thanks: @​evilgensec
• stats/opentelemetry: Record retry attempts, grpc.previous-rpc-attempts, at the call level and not the attempt level. (#8923)
• encoding: Ensure Close() is always called on readers returned from Compressor.Decompress if possible. (#9135)
• channelz: Fix the LastMessageSentTimestamp and LastMessageReceivedTimestamp fields in SocketMetrics to ensure they contain correct timestamp values. (#9109)

Release 1.81.1

Security

• xds/rbac: Fix a potential authorization bypass caused by incorrectly falling through URI/DNS SANs to Subject Distinguished Name (DN) when matching the authenticated principal name. With this fix, only the first non-empty identity source will be used, as per gRFC A41. (#9111)
  • Special Thanks: @​al4an444

Bug Fixes

• otel: Segregate client and server RPC information used for metrics and traces, to avoid one overwriting the other. (#9081)

Pull Request Overview

This PR updates google.golang.org/grpc from 1.79.3 to 1.82.1, along with several transitive dependencies. The analysis shows that the project remains up to standards following the update. However, there is a potential risk regarding gRPC-specific behavioral changes introduced in this release range. Specifically, the removal of options to disable strict path checking and the transition to a case-sensitive balancer registry may impact existing service logic. There is currently no evidence in the PR that the test suite has been executed specifically to validate these new constraints.

About this PR

• The upgrade introduces significant behavioral changes, including the removal of the option to disable strict path checking and making the balancer policy registry case-sensitive. Please ensure the existing gRPC implementation is compatible with these new constraints, as the current PR does not provide verification that these changes were validated.

Test suggestions

• Verify that the go.mod file accurately reflects the upgrade to google.golang.org/grpc v1.82.1.
• Execute the full test suite to ensure compatibility with new gRPC behavior changes, such as mandatory strict path checking and case-sensitive balancer registries.
