Change Details

Since c67f3b8b78e the sockbuf mutexes belong to the containing socket, and socket buffers just point to it. In 74a68313b50 macros that access this mutex directly were added. Prefer them over old macros, so that we can use so*wakeup() on sockets that have protocol specific socket buffers.

Since c67f3b8b78e the sockbuf mutexes belong to the containing socket, and socket buffers just point to it. In 74a68313b50 macros that access this mutex directly were added. Go over the core socket code and eliminate code that reaches the mutex by dereferencing the sockbuf compatibility pointer. This change requires a KPI change, as some functions were given the sockbuf pointer only without any hint if it is a receive or send buffer. This change doesn't cover the whole kernel, many protocols still use compatibility pointers internally. However, it allows operation of a protocol that doesn't use them.
