audit: optimize audit_compare_dname_path

2012-10-12T04:32:02Z

In the cases where we already know the length of the parent, pass it as a parm so we don't need to recompute it. In the cases where we don't know the length, pass in AUDIT_NAME_FULL (-1) to indicate that it should be determined. Signed-off-by: Jeff Layton Signed-off-by: Al Viro

audit: remove dirlen argument to audit_compare_dname_path

2012-10-12T04:32:01Z

All the callers set this to NULL now. Signed-off-by: Jeff Layton Signed-off-by: Al Viro

audit: set the name_len in audit_inode for parent lookups

2012-10-12T04:32:01Z

Currently, this gets set mostly by happenstance when we call into audit_inode_child. While that might be a little more efficient, it seems wrong. If the syscall ends up failing before audit_inode_child ever gets called, then you'll have an audit_names record that shows the full path but has the parent inode info attached. Fix this by passing in a parent flag when we call audit_inode that gets set to the value of LOOKUP_PARENT. We can then fix up the pathname for the audit entry correctly from the get-go. While we're at it, clean up the no-op macro for audit_inode in the !CONFIG_AUDITSYSCALL case. Signed-off-by: Jeff Layton Signed-off-by: Al Viro

userns: Convert audit to work with user namespaces enabled

2012-09-18T08:00:26Z

- Explicitly format uids gids in audit messges in the initial user namespace. This is safe because auditd is restrected to be in the initial user namespace. - Convert audit_sig_uid into a kuid_t. - Enable building the audit code and user namespaces at the same time. The net result is that the audit subsystem now uses kuid_t and kgid_t whenever possible making it almost impossible to confuse a raw uid_t with a kuid_t preventing bugs.

audit: Add typespecific uid and gid comparators

2012-09-18T01:08:09Z

The audit filter code guarantees that uid are always compared with uids and gids are always compared with gids, as the comparason operations are type specific. Take advantage of this proper to define audit_uid_comparator and audit_gid_comparator which use the type safe comparasons from uidgid.h. Build on audit_uid_comparator and audit_gid_comparator and replace audit_compare_id with audit_compare_uid and audit_compare_gid. This is one of those odd cases where being type safe and duplicating code leads to simpler shorter and more concise code. Don't allow bitmask operations in uid and gid comparisons in audit_data_to_entry. Bitmask operations are already denined in audit_rule_to_entry. Convert constants in audit_rule_to_entry and audit_data_to_entry into kuids and kgids when appropriate. Convert the uid and gid field in struct audit_names to be of type kuid_t and kgid_t respectively, so that the new uid and gid comparators can be applied in a type safe manner.

audit: remove AUDIT_SETUP_CONTEXT as it isn't used

2012-01-17T21:16:57Z

Audit contexts have 3 states. Disabled, which doesn't collect anything, build, which collects info but might not emit it, and record, which collects and emits. There is a 4th state, setup, which isn't used. Get rid of it. Signed-off-by: Eric Paris

audit: make functions static

2010-10-30T05:42:19Z

I was doing some namespace checks and found some simple stuff in audit that could be cleaned up. Make some functions static, and put const on make_reply payload arg. Signed-off-by: Stephen Hemminger Signed-off-by: Al Viro

Audit: split audit watch Kconfig

2010-07-28T13:58:19Z

Audit watch should depend on CONFIG_AUDIT_SYSCALL and should select FSNOTIFY. This splits the spagetti like mixing of audit_watch and audit_filter code so they can be configured seperately. Signed-off-by: Eric Paris

audit: do not get and put just to free a watch

2010-07-28T13:58:17Z

deleting audit watch rules is not currently done under audit_filter_mutex. It was done this way because we could not hold the mutex during inotify manipulation. Since we are using fsnotify we don't need to do the extra get/put pair nor do we need the private list on which to store the parents while they are about to be freed. Signed-off-by: Eric Paris

Audit: clean up the audit_watch split

2010-07-28T13:58:16Z

No real changes, just cleanup to the audit_watch split patch which we done with minimal code changes for easy review. Now fix interfaces to make things work better. Signed-off-by: Eric Paris
