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": "52c1da39534fb382c061de58b65f678ad74b59f5", "tree": "92b18695f23afbc99374f844445f555a198978f2", "parents": [ "d763b7a4736e219528f77bf6bc75dd78b1d75c03" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Thu Jun 23 22:05:33 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Fri Jun 24 00:06:43 2005 -0700" }, "message": "[PATCH] make various thing static\n\nAnother rollup of patches which give various symbols static scope\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
