2022-07-24io_uring: split network related opcodes into its own fileJens Axboe

2022-07-24io_uring: move epoll handler to its own fileJens Axboe
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 <axboe@kernel.dk>
2022-07-24io_uring: add a dummy -EOPNOTSUPP prep handlerJens Axboe

2022-07-24io_uring: handle completions in the coreJens Axboe
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 Axboe
Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-07-24io_uring: add io_uring_types.hJens Axboe
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 Axboe
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 Axboe
They are really just a subset of each other, just use the one type. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-07-24io_uring: convert iouring_cmd to io_cmd_typeJens Axboe

2022-07-24io_uring: convert file system request types to use io_cmd_typeJens Axboe
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 madvise/fadvise to use io_cmd_typeJens Axboe

Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-07-24io_uring: convert the sync and fallocate paths to use io_cmd_typeJens Axboe
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 Axboe
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 Axboe
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 Axboe
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 Axboe
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 Axboe
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 Axboe
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 Axboe
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 Axboe
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 Axboe
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>
2022-07-24Documentation: fix sctp_wmem in ip-sysctl.rstXin Long
Since commit 1033990ac5b2 ("sctp: implement memory accounting on tx path"), SCTP has supported memory accounting on tx path where 'sctp_wmem' is used by sk_wmem_schedule(). So we should fix the description for this option in ip-sysctl.rst accordingly. v1->v2: - Improve the description as Marcelo suggested.

2022-07-24net/tls: Remove the context from the list in tls_device_downMaxim Mikityanskiy
tls_device_down takes a reference on all contexts it's going to move to the degraded state (software fallback). If sk_destruct runs afterwards, it can reduce the reference counter back to 1 and return early without destroying the context. Then tls_device_down will release the reference it took and call tls_device_free_ctx. However, the context will still stay in tls_device_down_list forever. The list will contain an item, memory for which is released, making a memory corruption possible. Fix the above bug by properly removing the context from all lists before any call to tls_device_free_ctx.
