As tested on Linux:

  • An SCM_RIGHTS ancillary message is "attached" to the range of data bytes sent in the same sendmsg() call.
  • However, as always, recvmsg() calls on the receiving end don't necessarily map 1:1 to sendmsg() calls. Messages can be coalesced or split.
  • The recvmsg() call that receives the first byte of the ancillary message's byte range also receives the ancillary message itself.
  • To prevent multiple ancillary messages being delivered

Cap'n Proto RPC protocol straw man
View rpc.capnp
# Recall that Cap'n Proto RPC allows messages to contain references to remote objects that
# implement interfaces. These references are called "capabilities", because they both designate
# the remote object to use and confer permission to use it.
# Cap'n Proto RPC takes place over a connection -- any bi-directional stream. The protocol does
# not distinguish between client and server as both ends can receive capabilities from the other
# and subsequently make calls to those capabilities.
# Capabilities are, at least initially, tied to connections. If the connection dies, all
# capabilities received through it are lost. The ability to persist capabilities across
