This patch adds an end of event record type. It will be sent by the kernel as the last record when a multi-record event is triggered. This will aid realtime analysis programs since they will now reliably know they have the last record to complete an event. The audit daemon filters this and will not write it to disk.

New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.

This patch modifies the current ipsec audit layer by breaking it up into purpose driven audit calls. So far, the only audit calls made are when add/delete an SA/policy. It had been discussed to give each key manager it's own calls to do this, but I found there to be much redundnacy since they did the exact same things, except for how they got auid and sid, so I combined them. The below audit calls can be made by any key manager. Hopefully, this is ok. Signed-off-by: NJoy Latten <latten@austin.ibm.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Selinux folks had been complaining about the lack of AVC_PATH records when audit is disabled. I must admit my stupidity - I assumed that avc_audit() really couldn't use audit_log_d_path() because of deadlocks (== could be called with dcache_lock or vfsmount_lock held). Shouldn't have made that assumption - it never gets called that way. It _is_ called under spinlocks, but not those. Since audit_log_d_path() uses ab->gfp_mask for allocations, kmalloc() in there is not a problem. IOW, the simple fix is sufficient: let's rip AUDIT_AVC_PATH out and simply generate pathname as part of main record. It's trivial to do.

Add TTY input auditing, used to audit system administrator's actions. This is required by various security standards such as DCID 6/3 and PCI to provide non-repudiation of administrator's actions and to allow a review of past actions if the administrator seems to overstep their duties or if the system becomes misconfigured for unknown reasons. These requirements do not make it necessary to audit TTY output as well. Compared to an user-space keylogger, this approach records TTY input using the audit subsystem, correlated with other audit events, and it is completely transparent to the user-space application (e.g. the console ioctls still work). TTY input auditing works on a higher level than auditing all system calls within the session, which would produce an overwhelming amount of mostly useless audit events. Add an "audit_tty" attribute, inherited across fork (). Data read from TTYs by process with the attribute is sent to the audit subsystem by the kernel. The audit netlink interface is extended to allow modifying the audit_tty attribute, and to allow sending explanatory audit events from user-space (for example, a shell might send an event containing the final command, after the interactive command-line editing and history expansion is performed, which might be difficult to decipher from the TTY input alone). Because the "audit_tty" attribute is inherited across fork (), it would be set e.g. for sshd restarted within an audited session. To prevent this, the audit_tty attribute is cleared when a process with no open TTY file descriptors (e.g. after daemon startup) opens a TTY. See https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a more detailed rationale document for an older version of this patch.

Hi, I have been working on some code that detects abnormal events based on audit system events. One kind of event that we currently have no visibility for is when a program terminates due to segfault - which should never happen on a production machine. And if it did, you'd want to investigate it. Attached is a patch that collects these events and sends them into the audit system.

Add support for a rule key, which can be used to tie audit records to audit rules. This is useful when a watched file is accessed through a link or symlink, as well as for general audit log analysis. Because this patch uses a string key instead of an integer key, there is a bit of extra overhead to do the kstrdup() when a rule fires. However, we're also allocating memory for the audit record buffer, so it's probably not that significant. I went ahead with a string key because it seems more user-friendly. Note that the user must ensure that filterkeys are unique. The kernel only checks for duplicate rules. Signed-off-by: NAmy Griffis <amy.griffis@hpd.com>

In this implementation, audit registers inotify watches on the parent directories of paths specified in audit rules. When audit's inotify event handler is called, it updates any affected rules based on the filesystem event. If the parent directory is renamed, removed, or its filesystem is unmounted, audit removes all rules referencing that inotify watch. To keep things simple, this implementation limits location-based auditing to the directory entries in an existing directory. Given a path-based rule for /foo/bar/passwd, the following table applies: passwd modified -- audit event logged passwd replaced -- audit event logged, rules list updated bar renamed -- rule removed foo renamed -- untracked, meaning that the rule now applies to the new location Audit users typically want to have many rules referencing filesystem objects, which can significantly impact filtering performance. This patch also adds an inode-number-based rule hash to mitigate this situation. The patch is relative to the audit git tree: http://kernel.org/git/?p=linux/kernel/git/viro/audit-current.git;a=summary and uses the inotify kernel API: http://lkml.org/lkml/2006/6/1/145Signed-off-by: NAmy Griffis <amy.griffis@hp.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

This patch adds audit support to POSIX message queues. It applies cleanly to the lspp.b15 branch of Al Viro's git tree. There are new auxiliary data structures, and collection and emission routines in kernel/auditsc.c. New hooks in ipc/mqueue.c collect arguments from the syscalls. I tested the patch by building the examples from the POSIX MQ library tarball. Build them -lrt, not against the old MQ library in the tarball. Here's the URL: http://www.geocities.com/wronski12/posix_ipc/libmqueue-4.41.tar.gz Do auditctl -a exit,always -S for mq_open, mq_timedsend, mq_timedreceive, mq_notify, mq_getsetattr. mq_unlink has no new hooks.
