You somehow managed to do the wrong rebase :) |
Tested IPC types include pipes, local domain sockets, and loopback TCP. Plenty of TODOs for future additions, such as further IPC variations.

Not fully tested/debugged as .. it crashes the kernel in the test_ipc_pipe_8k_tagstripped test.

…ting stuck if the 8k send leads to the child blocking before all bytes have been sent.

A small set of tests attempting to validate that tagged capabilities have their tags stripped when transiting pipe IPC, local domain sockets, and loopback TCP sockets. Two message sizes are used: pointer-sized, and 8KiB, in attempts to exercise quite different paths in the pipe code. There are plenty of TODOs for potential future test additions.
