fuse: move request timeout code to a new source file This marks the first step in cleanly separating the transport layer from the filesystem layer. Add "dev.h", which will contain the interface definition for the transport layer. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2026-03-10 16:45:20 +01:00
fuse: add struct fuse_chan The goal is to separate transport layer stuff out from struct fuse_conn, leaving just the filesystem related members. Add a new object referenced from fuse_conn. This patch just implements the allocation and freeing of this object. Following patches will move transport related members from fuse_conn to fuse_chan. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

fuse: move background queuing related members to fuse_chan Move: - max_background - num_background - active_background - bg_queue - bg_lock Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

fuse: split out filesystem part of request sending Create a new source file: req.c and add the request sending entry functions: __fuse_simple_request() fuse_simple_background() fuse_simple_notify_reply() Introduce transport layer sending functions that are called by the respective fs layer function: fuse_chan_send() fuse_chan_send_bg() fuse_chan_send_notify_reply() Move calculation of request header fields uid, gid and pid from fuse_get_req() and fuse_force_creads() to a new helper: fuse_fill_creds(). These fileds are now passed to the transport layer via struct fuse_args. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

fuse: remove #include "fuse_i.h" from dev.c and dev_uring.c Move a couple of function declarations from fuse_i.h to dev.h and fuse_dev_i.h. Add fuse_conn_get_id() helper that retrieves the connection ID (s_dev) from fuse_conn. With the exception of cuse.c, virtio_fs.c and trace.c source files now either include fuse_i.h or fuse_dev_i/dev_uring_i.h but not both. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

fuse: set params in fuse_chan_set_initialized() Set minor, max_write and max_pages in the fuse_chan. These match the same fields in fuse_conn but are needed in both layers. [Dongyang Jin: Pointers should use NULL instead of explicit '0'] Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

fuse: decouple fuse_ring creation from ent registration Currently, the connection's fuse_ring is created lazily on the first FUSE_IO_URING_CMD_REGISTER command. A server registers entries from one thread per queue (one per CPU) and those threads issue their first REGISTER command concurrently. They then race to create the single per-connection fuse_ring, which required open-coded handling in fuse_uring_create() to detect and protect against concurrent creations. Decouple fuse_ring creation from ent registration and move it to FUSE_INIT reply processing after a server has negotiated and set FUSE_OVER_IO_URING. The ring is published before the connection is marked initialized. fuse_uring_register() no longer creates the ring and it instead uses the ring set up at init time.
