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 As was suggested by Eric Biederman the struct iattr in the\nsysfs_dirent structure has been replaced by a structure which contains the\niattr, secdata and secdata length to allow the changes to persist in the event\nthat the inode representing the sysfs_dirent is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.

as long as sysfs attributes cannot commit suicide directly and we\nare stuck with this callback mechanism, put the sysfs callbacks on\ntheir own workqueue instead of the global one.\n\nThis has the side benefit that if a suicidal sysfs attribute kicks\noff a long chain of -\u003eremove callbacks, we no longer induce a long\ndelay on the global queue.\n\nThis also fixes a missing module_put in the error path introduced\nby sysfs-only-allow-one-scheduled-removal-callback-per-kobj.patch.\n\nWe never destroy the workqueue, but I\u0027m not sure that\u0027s a\nproblem.\n\nReported-by: Kenji
