* VFS : mount lock scalability for internal mountsTim Chen2011-07-241-0/+1
| | | | | | | | | | | | | | | | | | | For a number of file systems that don't have a mount point (e.g. sockfs and pipefs), they are not marked as long term. Therefore in mntput_no_expire, all locks in vfs_mount lock are taken instead of just local cpu's lock to aggregate reference counts when we release reference to file objects. In fact, only local lock need to have been taken to update ref counts as these file systems are in no danger of going away until we are ready to unregister them. The attached patch marks file systems using kern_mount without mount point as long term. The contentions of vfs_mount lock is now eliminated. Before un-registering such file system, kern_unmount should be called to remove the long term flag and make the mount point ready to be freed.

This patch enables to accept percent-encoded object names as forth argument of /selinux/create interface to avoid possible bugs when we give an object name including whitespace or multibutes. E.g) if and when a userspace object manager tries to create a new object named as "resolve.conf but fake", it shall give this name as the forth argument of the /selinux/create. But sscanf() logic in kernel space fetches only the part earlier than the first whitespace. In this case, selinux may unexpectedly answer a default security context configured to "resolve.conf", but it is bug. Although I could not test this patch on named TYPE_TRANSITION rules actually, But debug printk() message seems to me the logic works correctly. I assume the libselinux provides an interface to apply this logic transparently, so nothing shall not be changed from the viewpoint of application.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a rather hot function that is called with a potentially NULL "struct common_audit_data" pointer argument. And in that case it has to provide and initialize its own dummy common_audit_data structure. However, all the _common_ cases already pass it a real audit-data structure, so that uncommon NULL case not only creates a silly run-time test, more importantly it causes that function to have a big stack frame for the dummy variable that isn't even used in the common case! So get rid of that stupid run-time behavior, and make the (few) functions that currently call with a NULL pointer just call a new helper function instead (naturally called inode_has_perm_noapd(), since it has no adp argument). This makes the run-time test be a static code generation issue instead, and allows for a much denser stack since none of the common callers need the dummy structure. And a denser stack not only means less stack space usage, it means better cache behavior. So we have a win-win-win from this simplification: less code executed, smaller stack footprint, and better cache behavior. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | selinux: don't pass in NULL avd to avc_has_perm_noauditLinus Torvalds2011-05-262-11/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now security_get_user_sids() will pass in a NULL avd pointer to avc_has_perm_noaudit(), which then forces that function to have a dummy entry for that case and just generally test it. Don't do it. The normal callers all pass a real avd pointer, and this helper function is incredibly hot. So don't make avc_has_perm_noaudit() do conditional stuff that isn't needed for the common case. This also avoids some duplicated stack space.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New inodes are created in a two stage process. We first will compute the label on a new inode in security_inode_create() and check if the operation is allowed. We will then actually re-compute that same label and apply it in security_inode_init_security(). The change to do new label calculations based in part on the last component of the path name only passed the path component information all the way down the security_inode_init_security hook. Down the security_inode_create hook the path information did not make it past may_create. Thus the two calculations came up differently and the permissions check might not actually be against the label that is created. Pass and use the same information in both places to harmonize the calculations and checks. Reported-by: Dominick Grift <domg472@gmail.com> Signed-off-by: Eric Paris <eparis@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now we walk to filename trans rule list for every inode that is created. First passes at policy using this facility creates around 5000 filename trans rules. Running a list of 5000 entries every time is a bad idea. This patch adds a new ebitmap to policy which has a bit set for each ttype that has at least 1 filename trans rule. Thus when an inode is created we can quickly determine if any rules exist for this parent directory type and can skip the list if we know there is definitely no relevant entry.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the security modules can decide whether they support the dcache RCU walk or not it's possible to make selinux a bit more RCU friendly. The SELinux AVC and security server access decision code is RCU safe. A specific piece of the LSM audit code may not be RCU safe. This patch makes the VFS RCU walk retry if it would hit the non RCU safe chunk of code. It will normally just work under RCU. This is done simply by passing the VFS RCU state as a flag down into the avc_audit() code and returning ECHILD there if it would have an issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6f5317e730505d5cbc851c435a2dfe3d5a21d343 introduced a bug in the handling of userspace object classes that is causing breakage for Xorg when XSELinux is enabled. Fix the bug by changing map_class() to return SECCLASS_NULL when the class cannot be mapped to a kernel object class. Reported-by: "Justin P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch allows /selinux/create takes optional 4th argument to support TYPE_TRANSITION with name extension for userspace object managers. If 4th argument is not supplied, it shall perform as existing kernel. In fact, the regression test of SE-PostgreSQL works well on the patched kernel.
