Bumps google.golang.org/grpc from 1.79.3 to 1.80.0.

Release notes

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

Release 1.80.0

Behavior Changes

  • balancer: log a warning if a balancer is registered with uppercase letters, as balancer names should be lowercase. In a future release, balancer names will be treated as case-insensitive; see #5288 for details. (#8837)
  • xds: update resource error handling and re-resolution logic (#8907)
    • Re-resolve all LOGICAL_DNS clusters simultaneously when re-resolution is requested.
    • Fail all in-flight RPCs immediately upon receipt of listener or route resource errors, instead of allowing them to complete.

Bug Fixes

  • xds: support the LB policy configured in LOGICAL_DNS cluster resources instead of defaulting to pick_first. (#8733)
  • credentials/tls: perform per-RPC authority validation against the leaf certificate instead of the entire peer certificate chain. (#8831)
  • xds: enabling A76 ring hash endpoint keys no longer causes EDS resources with invalid proxy metadata to be NACKed when HTTP CONNECT (gRFC A86) is disabled. (#8875)
  • xds: validate that the sum of endpoint weights in a locality does not exceed the maximum uint32 value. (#8899)
  • xds: fix incorrect proto field access in the weighted round robin (WRR) configuration where blackout_period was used instead of weight_expiration_period. (#8915)
  • xds/rbac: handle addresses with ports in IP matchers. (#8990)

New Features

  • ringhash: enable gRFC A76 (endpoint hash keys and request hash headers) by default. (#8922)

Performance Improvements

  • credentials/alts: pool write buffers to reduce memory allocations and usage. (#8919)
  • grpc: enable the use of pooled write buffers for buffering HTTP/2 frame writes by default. This reduces memory usage when connections are idle. Use the WithSharedWriteBuffer dial option or the SharedWriteBuffer server option to disable this feature. (#8957)
  • xds/priority: stop caching child LB policies removed from the configuration. This will help reduce memory and cpu usage when localities are constantly switching between priorities. (#8997)
  • mem: add a faster tiered buffer pool; use the experimental mem.NewBinaryTieredBufferPool function to create such pools. (#8775)
