The original OOPS is described in the\ncommit 2d3a4e3666325a9709cc8ea2e88151394e8f20fc:\n\n    Typical PDE creation code looks like:\n\n    \tpde \u003d create_proc_entry(\"foo\", 0, NULL);\n    \tif (pde)\n    \t\tpde-\u003eproc_fops \u003d \u0026foo_proc_fops;\n\n    Notice that PDE is first created, only then -\u003eproc_fops is set up to\n    final value. This is a problem because right after creation\n    a) PDE is fully visible in /proc , and\n    b) -\u003eproc_fops are proc_file_operations which do not have -\u003eopen callback. So, it\u0027s\n       possible to -\u003eread without -\u003eopen (see one class of oopses below).\n\n    The fix is new API called proc_create() which makes sure -\u003eproc_fops are\n    set up before gluing PDE to main tree. Typical new code looks like:\n\n    \tpde \u003d proc_create(\"foo\", 0, NULL, \u0026foo_proc_fops);\n    \tif (!pde)\n    \t\treturn -ENOMEM;\n\n    Fix most networking users for a start.\n\n    In the long run, create_proc_entry() for regular files will go.\n\nIn addition to this, proc_create_data is introduced to fix reading from\nproc without PDE-\u003edata. The race is basically the same as above.\n\ncreate_proc_entries is replaced in the entire kernel code as new method\nis also simply better.\n\nThis patch:\n\nThe problem is the same as for de-\u003eproc_fops.  Right now PDE becomes visible\nwithout data set.  So, the entry could be looked up without data.  This, in\nmost cases, will simply OOPS.\n\nproc_create_data call is created to address this issue.  proc_create now\nbecomes a wrapper around it.\n\nSigned-off-by: Denis V.

This is a problem because right after creation\na) PDE is fully visible in /proc , and\nb) -\u003eproc_fops are proc_file_operations which do not have -\u003eopen callback. So, it\u0027s\n   possible to -\u003eread without -\u003eopen (see one class of oopses below).\n\nThe fix is new API called proc_create() which makes sure -\u003eproc_fops are\nset up before gluing PDE to main tree.

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"
