This\nbug actually manifested itself with \u0027krusader\u0027 trying to open a file for\nwriting under sshfs.  Thanks to Eduard Czimbalmos for the report.\n\nThe problem can be solved just by making open() uninterruptible, because in\nthis case it was the truncate operation that slowed down the progress.

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"
