But\nstill, a bug is a bug.\n\nThe race happens when put_namespace() is called by another task, while\nmark_mounts_for_expiry() is between atomic_read() and get_namespace(). In\nthat case get_namespace() will be called on an already dead namespace with\nunforeseeable results.\n\nThe solution was suggested by Al Viro, with his own words:\n\n Instead of screwing with atomic_read() in there, why don\u0027t we\n simply do the following:\n \ta) atomic_dec_and_lock() in put_namespace()\n \tb) __put_namespace() called without dropping lock\n \tc) the first thing done by __put_namespace would be\n struct vfsmount *root \u003d namespace-\u003eroot;\n namespace-\u003eroot \u003d NULL;\n spin_unlock(...);\n ....\n umount_tree(root);\n ...\n \td) check in mark_... would be simply namespace \u0026\u0026 namespace-\u003eroot.\n\n And we are all set; no screwing around with atomic_read(), no magic\n at all. Dying namespace gets NULL -\u003eroot.\n All changes of -\u003eroot happen under spinlock.\n If under a spinlock we see non-NULL -\u003emnt_namespace, it won\u0027t be\n freed until we drop the lock (we will set -\u003emnt_namespace to NULL\n under that lock before we get to freeing namespace).\n If under a spinlock we see non-NULL -\u003emnt_namespace and\n -\u003emnt_namespace-\u003eroot, we can grab a reference to namespace and be\n sure that it won\u0027t go away.\n\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nAcked-by: Al Viro \u003cviro@parcelfarce.linux.theplanet.co.uk\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "202322e6f7cd12e82b5ff0fa92bbdf517fcf0947", "tree": "82c1f7b4b97d5b31654157a8f427a5c8d546504f", "parents": [ "6f50142e4b092a469920a0008fc23121c3d99f2f" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Thu Jul 07 17:57:22 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jul 07 18:23:51 2005 -0700" }, "message": "[PATCH] namespace.c: fix mnt_namespace clearing\n\nThis patch clears mnt_namespace on unmount.\n\nNot clearing mnt_namespace has two effects:\n\n 1) It is possible to attach a new mount to a detached mount,\n because check_mnt() returns true.\n\n This means, that when no other references to the detached mount\n remain, it still can\u0027t be freed.
