  "message": "proc: proc_pid_ns takes super_block as an argument\n\nsyzbot found that\n\n  touch /proc/testfile\n\ncauses NULL pointer dereference at tomoyo_get_local_path()\nbecause inode of the dentry is NULL.\n\nBefore c59f415a7cb6, Tomoyo received pid_ns from proc\u0027s s_fs_info\ndirectly. Since proc_pid_ns() can only work with inode, using it in\nthe tomoyo_get_local_path() was wrong.\n\nTo avoid creating more functions for getting proc_ns, change the\nargument type of the proc_pid_ns() function. Then, Tomoyo can use\nthe existing super_block to get pid_ns.\n\nLink: https://lkml.kernel.org/r/0000000000002f0c7505a5b0e04c@google.com\nLink: https://lkml.kernel.org/r/20200518180738.2939611-1-gladkov.alexey@gmail.com\nReported-by: syzbot+c1af344512918c61362c@syzkaller.appspotmail.com\nFixes: c59f415a7cb6 (\"Use proc_pid_ns() to get pid_namespace from the proc superblock\")\nSigned-off-by: Alexey Gladkov \u003cgladkov.alexey@gmail.com\u003e\nSigned-off-by: Eric W.
