| |
| - Add io_uring_{major,minor,check}_version() functions. |
| - Add IO_URING_{MAJOR,MINOR,CHECK}_VERSION() macros. |
| - FFI support (for non-C/C++ languages integration). |
| - Add io_uring_prep_msg_ring_cqe_flags() function. |
| - Deprecate --nolibc configure option. |
| - CONFIG_NOLIBC is always enabled on x86-64, x86, and aarch64. |
| - Add support for IORING_REGISTER_USE_REGISTERED_RING and use if available. |
| - Add io_uring_close_ring_fd() function. |
| - Add io_uring_prep_msg_ring_fd_alloc function. |
| - Add io_uring_free_buf_ring() and io_uring_setup_buf_ring() functions. |
| - Ensure that io_uring_prep_accept_direct(), io_uring_prep_openat_direct(), |
| io_uring_prep_openat2_direct(), io_uring_prep_msg_ring_fd(), and |
| io_uring_prep_socket_direct() factor in being called with |
| IORING_FILE_INDEX_ALLOC for allocating a direct descriptor. |
| - Add io_uring_prep_sendto() function. |
| - Add io_uring_prep_cmd_sock() function. |
| |
| liburing-2.3 release |
| |
| - Support non-libc build for aarch64. |
| - Add io_uring_{enter,enter2,register,setup} syscall functions. |
| - Add sync cancel interface, io_uring_register_sync_cancel(). |
| - Fix return value of io_uring_submit_and_wait_timeout() to match the |
| man page. |
| - Improvements to the regression tests |
| - Add support and test case for passthrough IO |
| - Add recv and recvmsg multishot helpers and support |
| - Add documentation and support for IORING_SETUP_DEFER_TASKRUN |
| - Fix potential missing kernel entry with IORING_SETUP_IOPOLL |
| - Add support and documentation for zero-copy network transmit |
| - Various optimizations |
| - Many cleanups |
| - Many man page additions and updates |
| |
| liburing-2.2 release |
| |
| - Support non-libc builds. |
| - Optimized syscall handling for x86-64/x86/aarch64. |
| - Enable non-lib function calls for fast path functions. |
| - Add support for multishot accept. |
| - io_uring_register_files() will set RLIMIT_NOFILE if necessary. |
| - Add support for registered ring fds, io_uring_register_ring_fd(), |
| reducing the overhead of an io_uring_enter() system call. |
| - Add support for the message ring opcode. |
| - Add support for newer request cancelation features. |
| - Add support for IORING_SETUP_COOP_TASKRUN, which can help reduce the |
| overhead of io_uring in general. Most applications should set this flag, |
| see the io_uring_setup.2 man page for details. |
| - Add support for registering a sparse buffer and file set. |
| - Add support for a new buffer provide scheme, see |
| io_uring_register_buf_ring.3 for details. |
| - Add io_uring_submit_and_wait_timeout() for submitting IO and waiting |
| for completions with a timeout. |
| - Add io_uring_prep_{read,write}v2 prep helpers. |
| - Add io_uring_prep_close_direct() helper. |
| - Add support for SQE128 and CQE32, which are doubly sized SQE and CQE |
| rings. This is needed for some cases of the new IORING_OP_URING_CMD, |
| notably for NVMe passthrough. |
| - ~5500 lines of man page additions, including adding ~90 new man pages. |
| - Synced with the 5.19 kernel release, supporting all the features of |
| 5.19 and earlier. |
| - 24 new regression test cases, and ~7000 lines of new tests in general. |
| - General optimizations and fixes. |
