2011-04-28SELinux: skip filename trans rules if ttype does not match parent dirEric Paris3-0/+17
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.

2011-04-26SELINUX: Make selinux cache VFS RCU walks safeEric Paris3-25/+55
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.

But head->r.w[0] was updated only when the string data was partially printed (because head->r.w[0] will be updated by head->r.w[1] later if completely printed). However, regarding /sys/kernel/security/tomoyo/query , an additional '\0' is printed after the string data was completely printed. But if free space for read buffer became 0 before printing the additional '\0', tomoyo_flush() was returning without updating head->r.w[0].

2011-03-24userns: security: make capabilities relative to the user namespaceSerge E. Hallyn4-20/+52
- Introduce ns_capable to test for a capability in a non-default user namespace. - Teach cap_capable to handle capabilities in a non-default user namespace. The motivation is to get to the unprivileged creation of new namespaces. It looks like this gets us 90% of the way there, with only potential uid confusion issues left. I still need to handle getting all caps after creation but otherwise I think I have a good starter patch that achieves all of your goals. Changelog: 11/05/2010: [serge] add apparmor 12/14/2010: [serge] fix capabilities to created user namespaces Without this, if user serge creates a user_ns, he won't have capabilities to the user_ns he created. THis is because we were first checking whether his effective caps had the caps he needed and returning -EPERM if not, and THEN checking whether he was the creator. Reverse those checks. 12/16/2010: [serge] security_real_capable needs ns argument in !security case 01/11/2011: [serge] add task_ns_capable helper 01/11/2011: [serge] add nsown_capable() helper per Bastian Blank suggestion 02/16/2011: [serge] fix a logic bug: the root user is always creator of init_user_ns, but should not always have capabilities to it! Fix the check in cap_capable(). 02/21/2011: Add the required user_ns parameter to security_capable, fixing a compile failure. 02/23/2011: Convert some macros to functions as per akpm comments. Some couldn't be converted because we can't easily forward-declare them (they are inline if !SECURITY, extern if SECURITY). Add a current_user_ns function so we can use it in capability.h without #including cred.h. Move all forward declarations together to the top of the #ifdef __KERNEL__ section, and use kernel-doc format. 02/23/2011: Per dhowells, clean up comment in cap_capable(). 02/23/2011: Per akpm, remove unreachable 'return -EPERM' in cap_capable.

Improve /proc/keys by: (1) Don't attempt to summarise the payload of a negated key. It won't have one. To this end, a helper function - key_is_instantiated() has been added that allows the caller to find out whether the key is positively instantiated (as opposed to being uninstantiated or negatively instantiated). (2) Do show keys that are negative, expired or revoked rather than hiding them. This requires an override flag (no_state_check) to be passed to search_my_process_keyrings() and keyring_search_aux() to suppress this check. Without this, keys that are possessed by the caller, but only grant permissions to the caller if possessed are skipped as the possession check fails. Keys that are visible due to user, group or other checks are visible with or without this patch. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>

2011-03-08KEYS: Add a new keyctl op to reject a key with a specified error codeDavid Howells6-13/+56
Add a new keyctl op to reject a key with a specified error code. This works much the same as negating a key, and so keyctl_negate_key() is made a special case of keyctl_reject_key(). The difference is that keyctl_negate_key() selects ENOKEY as the error to be reported. Typically the key would be rejected with EKEYEXPIRED, EKEYREVOKED or EKEYREJECTED, but this is not mandatory.

2011-03-08KEYS: Add a key type op to permit the key description to be vettedDavid Howells1-0/+8
Add a key type operation to permit the key type to vet the description of a new key that key_alloc() is about to allocate. The operation may reject the description if it wishes with an error of its choosing. If it does this, the key will not be allocated.
