Merge tag 'for-6.7/io_uring-sockopt-2023-10-30' of git://git.kernel.dk/linux
Pull io_uring {get,set}sockopt support from Jens Axboe: "This adds support for using getsockopt and setsockopt via io_uring. The main use cases for this is to enable use of direct descriptors, rather than first instantiating a normal file descriptor, doing the option tweaking needed, then turning it into a direct descriptor. With this support, we can avoid needing a regular file descriptor completely. The net and bpf bits have been signed off on their side" * tag 'for-6.7/io_uring-sockopt-2023-10-30' of git://git.kernel.dk/linux: selftests/bpf/sockopt: Add io_uring support io_uring/cmd: Introduce SOCKET_URING_OP_SETSOCKOPT io_uring/cmd: Introduce SOCKET_URING_OP_GETSOCKOPT io_uring/cmd: return -EOPNOTSUPP if net is disabled selftests/net: Extract uring helpers to be reusable tools headers: Grab copy of io_uring.h io_uring/cmd: Pass compat mode in issue_flags net/socket: Break down __sys_getsockopt net/socket: Break down __sys_setsockopt bpf: Add sockptr support for setsockopt bpf: Add sockptr support for getsockopt
