[PATCH] add securityfs for all LSMs to use Here's a small patch against 2.6.13-rc2 that adds securityfs, a virtual fs that all LSMs can use instead of creating their own. The fs should be mounted at /sys/kernel/security, and the fs creates that mount point. This will make the LSB people happy that we aren't creating a new /my_lsm_fs directory in the root for every different LSM. It has changed a bit since the last version, thanks to comments from Mike Waychison. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Chris Wright <chrisw@osdl.org>

security: fs: make inode explicitly non-modular The Makefile/Kconfig entry controlling compilation of this code is: security/Makefile:obj-$(CONFIG_SECURITYFS) += inode.o security/Kconfig:config SECURITYFS security/Kconfig: bool "Enable the securityfs filesystem" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. The removal of module.h uncovered a couple previously hidden implicit header requirements which are now included explicitly. Cc: James Morris <jmorris@namei.org> Cc: "Serge E.

LSM: Add /sys/kernel/security/lsm I am still tired of having to find indirect ways to determine what security modules are active on a system. I have added /sys/kernel/security/lsm, which contains a comma separated list of the active security modules. No more groping around in /proc/filesystems or other clever hacks.

fs: constify tree_descr arrays passed to simple_fill_super() simple_fill_super() is passed an array of tree_descr structures which describe the files to create in the filesystem's root directory. Since these arrays are never modified intentionally, they should be 'const' so that they are placed in .rodata and benefit from memory protection.

[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

[PATCH] add securityfs for all LSMs to use Here's a small patch against 2.6.13-rc2 that adds securityfs, a virtual fs that all LSMs can use instead of creating their own. The fs should be mounted at /sys/kernel/security, and the fs creates that mount point. This will make the LSB people happy that we aren't creating a new /my_lsm_fs directory in the root for every different LSM. It has changed a bit since the last version, thanks to comments from Mike Waychison. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Chris Wright <chrisw@osdl.org>

securityfs: fix object creation races inode needs to be fully set up before we feed it to d_instantiate(). securityfs_create_file() does *not* do so; it sets ->i_fop and ->i_private only after we'd exposed the inode. Unfortunately, that's done fairly deep in call chain, so the amount of churn is considerable. Helper functions killed by substituting into their solitary call sites, dead code removed. We finally can bury default_file_ops, now that the final value of ->i_fop is available (and assigned) at the point where inode is allocated.

[PATCH] add securityfs for all LSMs to use Here's a small patch against 2.6.13-rc2 that adds securityfs, a virtual fs that all LSMs can use instead of creating their own. The fs should be mounted at /sys/kernel/security, and the fs creates that mount point. This will make the LSB people happy that we aren't creating a new /my_lsm_fs directory in the root for every different LSM. It has changed a bit since the last version, thanks to comments from Mike Waychison. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Chris Wright <chrisw@osdl.org>

lsm: add new securityfs delete function When deleting a directory in the security file system, the existing securityfs_remove requires the directory to be empty, otherwise it will do nothing. This leads to a potential risk that the security file system might be in an unclean state when the intended deletion did not happen. This commit introduces a new function securityfs_recursive_remove to recursively delete a directory without leaving an unclean state.

LSM: Add /sys/kernel/security/lsm I am still tired of having to find indirect ways to determine what security modules are active on a system. I have added /sys/kernel/security/lsm, which contains a comma separated list of the active security modules. No more groping around in /proc/filesystems or other clever hacks. Unchanged from previous versions except for being updated to the latest security next branch.
