Protos in this dir are generated using buildprotos.py and manually checked into the tree. The source of the protos is src/config/proto/chromiumos/config/api/test/tls/commontls.proto, and src/config/proto/chromiumos/config/api/test/tls/dependencies/longrunning/operations.proto relative to a standard repo. (https://chromium.git.corp.google.com/chromiumos/config/+/HEAD/proto/chromiumos/config/api/test/tls/commontls.proto) If there are updates to src proto, the protos here must be re-generated. Run the script "buildprotos.py" to automatically rebuild them from the source. You must manually repo sync prior to this. If there are changes to the file structure in the source, buildprotos.py will need to be updated for this.
