2022-07-24io_uring: move remaining file table manipulation to filetable.cJens Axboe4-88/+90
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move rsrc related data, core, and commandsJens Axboe6-1418/+1480
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: split provided buffers handling into its own fileJens Axboe7-636/+672
Move both the opcodes related to it, and the internals code dealing with it. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move cancelation into its own fileJens Axboe6-178/+204
This also helps cleanup the io_uring.h cancel parts, as we can make things static in the cancel.c file, mostly. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move poll handling into its own fileJens Axboe6-827/+879
Add a io_poll_issue() rather than export the general task_work locking and io_issue_sqe(), and put the io_op_defs definition and structure into a separate header file so that poll can use it. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: add opcode name to io_op_defsJens Axboe1-98/+52
This kills the last per-op switch. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: include and forward-declaration sanitationJens Axboe1-12/+5
Remove some dead headers we no longer need, and get rid of the io_ring_ctx and io_uring_fops forward declarations. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move io_uring_task (tctx) helpers into its own fileJens Axboe5-365/+396
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move fdinfo helpers to its own fileJens Axboe6-208/+230
This also means moving a bit more of the fixed file handling to the filetable side, which makes sense separately too. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: use io_is_uring_fops() consistentlyJens Axboe1-8/+8
Convert the last spots that check for io_uring_fops to use the provided helper instead. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move SQPOLL related handling into its own fileJens Axboe5-462/+497
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move timeout opcodes and handling into its own fileJens Axboe6-660/+701
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move our reference counting into a headerJens Axboe2-42/+49
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move msg_ring into its own fileJens Axboe4-55/+71
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: split network related opcodes into its own fileJens Axboe5-835/+884
While at it, convert the handlers to just use io_eopnotsupp_prep() if CONFIG_NET isn't set. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move statx handling to its own fileJens Axboe4-62/+82
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move epoll handler to its own fileJens Axboe4-50/+70
Would be nice to sort out Kconfig for this and don't even compile epoll.c if we don't have epoll configured. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: add a dummy -EOPNOTSUPP prep handlerJens Axboe1-9/+14
Add it and use it for the epoll handling, if epoll isn't configured. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move uring_cmd handling to its own fileJens Axboe5-124/+142
Signed-off-by: Jens Axboe <[email protected]>

Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: split out fs related sync/fallocate functionsJens Axboe4-97/+124

2022-07-24io_uring: split out splice related operationsJens Axboe5-130/+154
This splits out splice and tee support. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: split out filesystem related operationsJens Axboe4-283/+316
This splits out renameat, unlinkat, mkdirat, symlinkat, and linkat. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move nop into its own fileJens Axboe4-15/+32
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: move xattr related opcodes to its own fileJens Axboe4-247/+277
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: handle completions in the coreJens Axboe2-134/+142
Normally request handlers complete requests themselves, if they don't return an error. For the latter case, the core will complete it for them. This is unhandy for pushing opcode handlers further out, as we don't want a bunch of inline completion code and we don't want to make the completion path slower than it is now. Let the core handle any completion, unless the handler explicitly asks us not to. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: set completion results upfrontJens Axboe2-12/+22
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: add io_uring_types.hJens Axboe2-488/+499
This adds definitions of structs that both the core and the various opcode handlers need to know about. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: define a request type cleanup handlerJens Axboe1-69/+86
This can move request type specific cleanup into a private handler, removing the need for the core io_uring parts to know what types they are dealing with. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: unify struct io_symlink and io_hardlinkJens Axboe1-20/+7
They are really just a subset of each other, just use the one type. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert iouring_cmd to io_cmd_typeJens Axboe1-8/+10
Signed-off-by: Jens Axboe <[email protected]>

Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert rsrc_update to io_cmd_typeJens Axboe1-16/+19
Signed-off-by: Jens Axboe <[email protected]>

Signed-off-by: Jens Axboe <[email protected]>

Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert epoll to io_cmd_typeJens Axboe1-7/+8
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert file system request types to use io_cmd_typeJens Axboe1-45/+57
This converts statx, rename, unlink, mkdir, symlink, and hardlink to use io_cmd_type. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert madvise/fadvise to use io_cmd_typeJens Axboe1-10/+12
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert open/close path to use io_cmd_typeJens Axboe1-32/+40
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert timeout path to use io_cmd_typeJens Axboe1-49/+68
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert cancel path to use io_cmd_typeJens Axboe1-11/+13
Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert the sync and fallocate paths to use io_cmd_typeJens Axboe1-19/+24
They all share the same struct io_sync, convert them to use the io_cmd_type approach instead. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert net related opcodes to use io_cmd_typeJens Axboe1-26/+27
This converts accept, connect, send/recv, sendmsg/recvmsg, shutdown, and socket to use io_cmd_type. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: remove recvmsg knowledge from io_arm_poll_handler()Jens Axboe1-2/+6
There's a special case for recvmsg with MSG_ERRQUEUE set. This is problematic as it means the core needs to know about this special request type. For now, just add a generic flag for it. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert poll_update path to use io_cmd_typeJens Axboe1-8/+8
Remove struct io_poll_update from io_kiocb, and convert the poll path to use the io_cmd_type approach instead. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert poll path to use io_cmd_typeJens Axboe1-25/+28
Remove struct io_poll_iocb from io_kiocb, and convert the poll path to use the io_cmd_type approach instead. While at it, rename io_poll_iocb to io_poll which is consistent with the other request type private structures. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: convert read/write path to use io_cmd_typeJens Axboe1-88/+106
Remove struct io_rw from io_kiocb, and convert the read/write path to use the io_cmd_type approach instead. Signed-off-by: Jens Axboe <[email protected]>
2022-07-24io_uring: add generic command payload type to struct io_kiocbJens Axboe1-4/+17
Each opcode generally has a command structure in io_kiocb which it can use to store data associated with that request. In preparation for having the core layer not know about what's inside these fields, add a generic io_cmd_data type and put in the union as well. Signed-off-by: Jens Axboe <[email protected]>
