Signed-off-by: Jens Axboe <axboe@kernel.dk>
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 <axboe@kernel.dk>
2022-07-24io_uring: set completion results upfrontJens Axboe2-12/+22
Signed-off-by: Jens Axboe <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>

Signed-off-by: Jens Axboe <axboe@kernel.dk>
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 <axboe@kernel.dk>

2022-07-24io_uring: convert cancel path to use io_cmd_typeJens Axboe1-11/+13
Signed-off-by: Jens Axboe <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
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 <axboe@kernel.dk>
2022-07-24io_uring: move req async preparation into opcode handlerJens Axboe1-28/+10
Define an io_op_def->prep_async() handler and push the async preparation to there. Since we now have that, we can drop ->needs_async_setup, as they mean the same thing. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-07-24io_uring: move to separate directoryJens Axboe8-10/+10
In preparation for splitting io_uring up a bit, move it into its own top level directory. It didn't really belong in fs/ anyway, as it's not a file system only API. This adds io_uring/ and moves the core files in there, and updates the MAINTAINERS file for the new location. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-07-24io_uring: define a 'prep' and 'issue' handler for each opcodeJens Axboe1-458/+350
Rather than have two giant switches for doing request preparation and then for doing request issue, add a prep and issue handler for each of them in the io_op_defs[] request definition. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2022-07-23x86/speculation: Make all RETbleed mitigations 64-bit onlyBen Hutchings1-4/+4
The mitigations for RETBleed are currently ineffective on x86_32 since entry_32.S does not use the required macros. However, for an x86_32 target, the kconfig symbols for them are still enabled by default and /sys/devices/system/cpu/vulnerabilities/retbleed will wrongly report that mitigations are in place. Make all of these symbols depend on X86_64, and only enable RETHUNK by default on X86_64.
