2015-05-12LSM: Switch to lists of hooksCasey Schaufler1-11/+3
Instead of using a vector of security operations with explicit, special case stacking of the capability and yama hooks use lists of hooks with capability and yama hooks included as appropriate. The security_operations structure is no longer required. Instead, there is a union of the function pointers that allows all the hooks lists to use a common mechanism for list management while retaining typing. Each module supplies an array describing the hooks it provides instead of a sparsely populated security_operations structure. The description includes the element that gets put on the hook list, avoiding the issues surrounding individual element allocation. The method for registering security modules is changed to reflect the information available. The method for removing a module, currently only used by SELinux, has also changed. It should be generic now, however if there are potential race conditions based on ordering of hook removal that needs to be addressed by the calling module. The security hooks are called from the lists and the first failure is returned.

2015-05-12LSM: Add security module hook list headsCasey Schaufler1-29/+29
Add a list header for each security hook. They aren't used until later in the patch series. They are grouped together in a structure so that there doesn't need to be an external address for each.

2015-04-17tomoyo: reduce mmap_sem hold for mm->exe_fileDavidlohr Bueso1-5/+8
The mm->exe_file is currently serialized with mmap_sem (shared) in order to both safely (1) read the file and (2) compute the realpath by calling tomoyo_realpath_from_path, making it an absolute overkill.

2015-01-06rcu: Make SRCU optional by using CONFIG_SRCUPranith Kumar1-0/+1
SRCU is not necessary to be compiled by default in all cases. For tinification efforts not compiling SRCU unless necessary is desirable. The current patch tries to make compiling SRCU optional by introducing a new Kconfig option CONFIG_SRCU which is selected when any of the components making use of SRCU are selected. If we do not select CONFIG_SRCU, srcu.o will not be compiled at all. text data bss dec hex filename 2007 0 0 2007 7d7 kernel/rcu/srcu.o Size of arch/powerpc/boot/zImage changes from text data bss dec hex filename 831552 64180 23944 919676 e087c arch/powerpc/boot/zImage : before 829504 64180 23952 917636 e0084 arch/powerpc/boot/zImage : after so the savings are about ~2000 bytes.

2012-03-01TOMOYO: Fix mount flags checking order.Tetsuo Handa1-18/+20
Userspace can pass in arbitrary combinations of MS_* flags to mount(). If both MS_BIND and one of MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE are passed, device name which should be checked for MS_BIND was not checked because MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE had higher priority than MS_BIND. If both one of MS_BIND/MS_MOVE and MS_REMOUNT are passed, device name which should not be checked for MS_REMOUNT was checked because MS_BIND/MS_MOVE had higher priority than MS_REMOUNT. Fix these bugs by changing priority to MS_REMOUNT -> MS_BIND -> MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE -> MS_MOVE as with do_mount() does. Also, unconditionally return -EINVAL if more than one of MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE is passed so that TOMOYO will not generate inaccurate audit logs, for commit 7a2e8a8f "VFS: Sanity check mount flags passed to change_mnt_propagation()" clarified that these flags must be exclusively passed.

2011-12-08TOMOYO: Fix pathname handling of disconnected paths.Tetsuo Handa1-1/+9
Current tomoyo_realpath_from_path() implementation returns strange pathname when calculating pathname of a file which belongs to lazy unmounted tree. Use local pathname rather than strange absolute pathname in that case. Also, this patch fixes a regression by commit 02125a82 "fix apparmor dereferencing potentially freed dentry, sanitize __d_path() API".
