For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "8b512d9a88875affe584bb3d2a7a235f84343b9e", "tree": "80c46a675aeffaedd8d18e2bb6361768f4f4845a", "parents": [ "5528f911b4c43a5de5da34bcbd7e3f2a62503617" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:18 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:18 2006 -0400" }, "message": "VFS: Remove dependency of -\u003eumount_begin() call on MNT_FORCE\n\nAllow filesystems to decide to perform pre-umount processing whether or not\nMNT_FORCE is set.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "8aa09a50b5d9dbdf627f79e19d72d82994348089", "tree": "5b50a1b62c8b95223023053595c452b0641f5767", "parents": [ "6dbbcb120570d747b00783820ee02d1e1bcf63de" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Wed Apr 26 10:49:16 2006 +0200" }, "committer": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Wed Apr 26 10:49:16 2006 +0200" }, "message": "[fuse] fix race between checking and setting file-\u003eprivate_data\n\nBKL does not protect against races if the task may sleep between\nchecking and setting a value.

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" } ] }
