The semantics of using splice() are:\n\n 1) buffer the message header and data in a temporary pipe\n 2) with a *single* splice() call move the message from the temporary pipe\n to the fuse device\n\nThe READ reply message has the most interesting use for this, since\nnow the data from an arbitrary file descriptor (which could be a\nregular file, a block device or a socket) can be tranferred into the\nfuse device without having to go through a userspace buffer. It will\nalso allow zero copy moving of pages.\n\nOne caveat is that the protocol on the fuse device requires the length\nof the whole message to be written into the header. But the length of\nthe data transferred into the temporary pipe may not be known in\nadvance. The current library implementation works around this by\nusing vmplice to write the header and modifying the header after\nsplicing the data into the pipe (error handling omitted):\n\n\tstruct fuse_out_header out;\n\n\tiov.iov_base \u003d \u0026out;\n\tiov.iov_len \u003d sizeof(struct fuse_out_header);\n\tvmsplice(pip[1], \u0026iov, 1, 0);\n\tlen \u003d splice(input_fd, input_offset, pip[1], NULL, len, 0);\n\t/* retrospectively modify the header: */\n\tout.len \u003d len + sizeof(struct fuse_out_header);\n\tsplice(pip[0], NULL, fuse_chan_fd(req-\u003ech), NULL, out.len, flags);\n\nThis works since vmsplice only saves a pointer to the data, it does\nnot copy the data itself.\n\nSince pipes are currently limited to 16 pages and messages need to be\nspliced atomically, the length of the data is limited to 15 pages (or\n60kB for 4k pages).\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n" }, { "commit": "37d217f029a56a6d385f99773fb27dfcb51f9a46", "tree": "90b8cf1f1b77d8ff732dc2ee8ab032aaabfbdcd1", "parents": [ "7a6d3c8b3049d07123628f2bf57127bba2cc878f" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Jul 08 18:17:58 2009 +0200" }, "committer": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Jul 08 18:17:58 2009 +0200" }, "message": "fuse: document protocol version negotiation\n\nClarify how the protocol version should be negotiated between kernel\nand userspace.

core\n\nThis patch adds FUSE core.\n\nThis contains the following files:\n\n o inode.c\n - superblock operations (alloc_inode, destroy_inode, read_inode,\n clear_inode, put_super, show_options)\n - registers FUSE filesystem\n\n o fuse_i.h\n - private header file\n\nRequirements\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\n The most important difference between orinary filesystems and FUSE is\n the fact, that the filesystem data/metadata is provided by a userspace\n process run with the privileges of the mount \"owner\" instead of the\n kernel, or some remote entity usually running with elevated\n privileges.\n\n The security implication of this is that a non-privileged user must\n not be able to use this capability to compromise the system. Obvious\n requirements arising from this are:\n\n - mount owner should not be able to get elevated privileges with the\n help of the mounted filesystem\n\n - mount owner should not be able to induce undesired behavior in\n other users\u0027 or the super user\u0027s processes\n\n - mount owner should not get illegitimate access to information from\n other users\u0027 and the super user\u0027s processes\n\n These are currently ensured with the following constraints:\n\n 1) mount is only allowed to directory or file which the mount owner\n can modify without limitation (write access + no sticky bit for\n directories)\n\n 2) nosuid,nodev mount options are forced\n\n 3) any process running with fsuid different from the owner is denied\n all access to the filesystem\n\n 1) and 2) are ensured by the \"fusermount\" mount utility which is a\n setuid root application doing the actual mount operation.\n\n 3) is ensured by a check in the permission() method in kernel\n\n I started thinking about doing 3) in a different way because Christoph\n H. made a big deal out of it, saying that FUSE is unacceptable into\n mainline in this form.\n\n The suggested use of private namespaces would be OK, but in their\n current form have many limitations that make their use impractical (as\n discussed in this thread).\n\n Suggested improvements that would address these limitations:\n\n - implement shared subtrees\n\n - allow a process to join an existing namespace (make namespaces\n first-class objects)\n\n - implement the namespace creation/joining in a PAM module\n\n With all that in place the check of owner against current-\u003efsuid may\n be removed from the FUSE kernel module, without compromising the\n security requirements.\n\n Suid programs still interesting questions, since they get access even\n to the private namespace causing some information leak (exact\n order/timing of filesystem operations performed), giving some\n ptrace-like capabilities to unprivileged users. BTW this problem is\n not strictly limited to the namespace approach, since suid programs\n setting fsuid and accessing users\u0027 files will succeed with the current\n approach too.\n\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ] }
