The patch uses hooks introduced in the\nprevious patch to handle the getting and setting of security information for\nthe sysfs inodes. As was suggested by Eric Biederman the struct iattr in the\nsysfs_dirent structure has been replaced by a structure which contains the\niattr, secdata and secdata length to allow the changes to persist in the event\nthat the inode representing the sysfs_dirent is evicted. Because sysfs only\nstores this information when a change is made all the optional data is moved\ninto one dynamically allocated field.\n\nThis patch addresses an issue where SELinux was denying virtd access to the PCI\nconfiguration entries in sysfs. The lack of setxattr handlers for sysfs\nrequired that a single label be assigned to all entries in sysfs. Granting virtd\naccess to every entry in sysfs is not an acceptable solution so fine grained\nlabeling of sysfs is required such that individual entries can be labeled\nappropriately.\n\n[sds: Fixed compile-time warnings, coding style, and setting of inode security init flags.]\n\nSigned-off-by: David P.

This patch implements active reference and\nmakes the association between kobject and sysfs immediately breakable.\n\nNow each sysfs_dirent has two reference counts - s_count and s_active.\ns_count is a regular reference count which guarantees that the\ncontaining sysfs_dirent is accessible. As long as s_count reference\nis held, all sysfs internal fields in sysfs_dirent are accessible\nincluding s_parent and s_name.\n\nThe newly added s_active is active reference count. This is acquired\nby invoking sysfs_get_active() and it\u0027s the caller\u0027s responsibility to\nensure sysfs_dirent itself is accessible (should be holding s_count\none way or the other). Dereferencing sysfs_dirent to access objects\nout of sysfs proper requires active reference. This includes access\nto the associated kobjects, attributes and ops.\n\nThe active references can be drained and denied by calling\nsysfs_deactivate(). All active sysfs_dirents must be deactivated\nafter deletion but before the default reference is dropped. This\nenables immediate disconnect of sysfs nodes. Once a sysfs_dirent is\ndeleted, it won\u0027t access any entity external to sysfs proper.\n\nBecause attr/bin_attr ops access both the node itself and its parent\nfor kobject, they need to hold active references to both.\nsysfs_get/put_active_two() helpers are provided to help grabbing both\nreferences. Parent\u0027s is acquired first and released last.\n\nUnlike other operations, mmapped area lingers on after mmap() is\nfinished and the module implement implementing it and kobj need to\nstay referenced till all the mapped pages are gone. This is\naccomplished by holding one set of active references to the bin_attr\nand its parent if there have been any mmap during lifetime of an\nopenfile. The references are dropped when the openfile is released.\n\nThis change makes sysfs lifetime rules independent from both kobject\u0027s\nand module\u0027s. It not only fixes several race conditions caused by\nsysfs not holding onto the proper module when referencing kobject, but\nalso helps fixing and simplifying lifetime management in driver model\nand drivers by taking sysfs out of the equation.\n\nPlease read the following message for more info.\n\n http://article.gmane.org/gmane.linux.kernel/510293\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "2b29ac252afff87b8465b064ca2d9740cf1f6e52", "tree": "9f4930db68ace50adc7c11feba12aafe34e2cdbe", "parents": [ "aecdcedaab49ca40620dc7dd70f67ee7269a66c9" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Jun 14 03:45:15 2007 +0900" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jul 11 16:09:04 2007 -0700" }, "message": "sysfs: reimplement symlink using sysfs_dirent tree\n\nsysfs symlink is implemented by referencing dentry and kobject from\nsysfs_dirent - symlink entry references kobject, dentry is used to\nwalk the tree.

With this patch, each sd points to and\nholds a reference to its parent. This allows walking sysfs tree\nwithout referencing sd-\u003es_dentry which can go away anytime if the user\ndoesn\u0027t control when it\u0027s deleted.\n\nsd-\u003es_parent is initialized and parent is referenced in\nsysfs_attach_dirent(). Reference to parent is released when the sd is\nreleased, so as long as reference to a sd is held, s_parent can be\nfollowed.\n\ndentry walk in sysfs_readdir() is convereted to s_parent walk.\n\nThis will be used to reimplement symlink such that it uses only\nsysfs_dirent tree.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "a26cd7226c24c3be5dd5f48a74832fe64beb8489", "tree": "0dfb4a15d800494a06a4ddf83c4d33812c404fac", "parents": [ "996b73764e9bb9d5e751fd15b130ba38637d66a8" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Jun 14 03:45:14 2007 +0900" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jul 11 16:09:04 2007 -0700" }, "message": "sysfs: consolidate sysfs_dirent creation functions\n\nCurrently there are four functions to create sysfs_dirent -\n__sysfs_new_dirent(), sysfs_new_dirent(), __sysfs_make_dirent() and\nsysfs_make_dirent().
