2006-06-20[PATCH] log more info for directory entry change eventsAmy Griffis
When an audit event involves changes to a directory entry, include a PATH record for the directory itself. A few other notable changes: - fixed audit_inode_child() hooks in fsnotify_move() - removed unused flags arg from audit_inode() - added audit log routines for logging a portion of a string Here's some sample output. before patch: type=SYSCALL msg=audit(1149821605.320:26): arch=40000003 syscall=39 success=yes exit=0 a0=bf8d3c7c a1=1ff a2=804e1b8 a3=bf8d3c7c items=1 ppid=739 pid=800 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=ttyS0 comm="mkdir" exe="/bin/mkdir" subj=root:system_r:unconfined_t:s0-s0:c0.c255 type=CWD msg=audit(1149821605.320:26): cwd="/root" type=PATH msg=audit(1149821605.320:26): item=0 name="foo" parent=164068 inode=164010 dev=03:00 mode=040755 ouid=0 ogid=0 rdev=00:00 obj=root:object_r:user_home_t:s0 after patch: type=SYSCALL msg=audit(1149822032.332:24): arch=40000003 syscall=39 success=yes exit=0 a0=bfdd9c7c a1=1ff a2=804e1b8 a3=bfdd9c7c items=2 ppid=714 pid=777 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=ttyS0 comm="mkdir" exe="/bin/mkdir" subj=root:system_r:unconfined_t:s0-s0:c0.c255 type=CWD msg=audit(1149822032.332:24): cwd="/root" type=PATH msg=audit(1149822032.332:24): item=0 name="/root" inode=164068 dev=03:00 mode=040750 ouid=0 ogid=0 rdev=00:00 obj=root:object_r:user_home_dir_t:s0 type=PATH msg=audit(1149822032.332:24): item=1 name="foo" inode=164010 dev=03:00 mode=040755 ouid=0 ogid=0 rdev=00:00 obj=root:object_r:user_home_t:s0 Signed-off-by: Amy Griffis <amy.griffis@hp.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2006-06-20[PATCH] audit: path-based rulesAmy Griffis
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/2006/6/1/145 Signed-off-by: Amy Griffis <amy.griffis@hp.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2006-06-20[PATCH] Audit of POSIX Message Queue Syscalls v.2George C. Wilson
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. Please see the corresponding userspace patch to get correct output from auditd for the new record types.

2006-06-20[PATCH] update of IPC audit record cleanupLinda Knippers
The following patch addresses most of the issues with the IPC_SET_PERM records as described in: https://www.redhat.com/archives/linux-audit/2006-May/msg00010.html and addresses the comments I received on the record field names. To summarize, I made the following changes: 1. Changed sys_msgctl() and semctl_down() so that an IPC_SET_PERM record is emitted in the failure case as well as the success case. This matches the behavior in sys_shmctl(). I could simplify the code in sys_msgctl() and semctl_down() slightly but it would mean that in some error cases we could get an IPC_SET_PERM record without an IPC record and that seemed odd. 2. No change to the IPC record type, given no feedback on the backward compatibility question. 3. Removed the qbytes field from the IPC record. It wasn't being set and when audit_ipc_obj() is called from ipcperms(), the information isn't available. If we want the information in the IPC record, more extensive changes will be necessary. Since it only applies to message queues and it isn't really permission related, it doesn't seem worth it. 4. Removed the obj field from the IPC_SET_PERM record. This means that the kern_ipc_perm argument is no longer needed. 5. Removed the spaces and renamed the IPC_SET_PERM field names. Replaced iuid and igid fields with ouid and ogid in the IPC record. I tested this with the lspp.22 kernel on an x86_64 box. I believe it applies cleanly on the latest kernel. -- ljk Signed-off-by: Linda Knippers <linda.knippers@hp.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2006-05-01[PATCH] Rework of IPC auditingSteve Grubb
1) The audit_ipc_perms() function has been split into two different functions: - audit_ipc_obj() - audit_ipc_set_perm() There's a key shift here... The audit_ipc_obj() collects the uid, gid, mode, and SElinux context label of the current ipc object. This audit_ipc_obj() hook is now found in several places. Most notably, it is hooked in ipcperms(), which is called in various places around the ipc code permforming a MAC check. Additionally there are several places where *checkid() is used to validate that an operation is being performed on a valid object while not necessarily having a nearby ipcperms() call. In these locations, audit_ipc_obj() is called to ensure that the information is captured by the audit system. The audit_set_new_perm() function is called any time the permissions on the ipc object changes. In this case, the NEW permissions are recorded (and note that an audit_ipc_obj() call exists just a few lines before each instance). 2) Support for an AUDIT_IPC_SET_PERM audit message type. This allows for separate auxiliary audit records for normal operations on an IPC object and permissions changes. Note that the same struct audit_aux_data_ipcctl is used and populated, however there are separate audit_log_format statements based on the type of the message. Finally, the AUDIT_IPC block of code in audit_free_aux() was extended to handle aux messages of this new type. No more mem leaks I hope ;-) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2006-05-01[PATCH] support for context based audit filteringDarrel Goeddel
The following patch provides selinux interfaces that will allow the audit system to perform filtering based on the process context (user, role, type, sensitivity, and clearance). These interfaces will allow the selinux module to perform efficient matches based on lower level selinux constructs, rather than relying on context retrievals and string comparisons within the audit module. It also allows for dominance checks on the mls portion of the contexts that are impossible with only string comparisons.

2006-03-20[PATCH] promiscuous modeSteve Grubb
Hi, When a network interface goes into promiscuous mode, its an important security issue. The attached patch is intended to capture that action and send an event to the audit system.

Other examples of potential kernel anomalies would be: exceeding disk quota, rlimit violations, changes to syscall entry table.

This patch extends existing audit records with subject/object context information.

These labels are collected via hooks in SELinux and appended to the appropriate record in the audit code. This additional information is required for Common Criteria Labeled Security Protection Profile (LSPP).

2006-03-20[PATCH] Collect more inode information during syscall processing.Amy Griffis
This patch augments the collection of inode info during syscall processing. It represents part of the functionality that was provided by the auditfs patch included in RHEL4. Specifically, it: - Collects information for target inodes created or removed during syscalls. Previous code only collects information for the target inode's parent. - Adds the audit_inode() hook to syscalls that operate on a file descriptor (e.g. fchown), enabling audit to do inode filtering for these calls. - Modifies filtering code to check audit context for either an inode # or a parent inode # matching a given rule. - Modifies logging to provide inode # for both parent and child. - Protect debug info from NULL audit_names.name.

2006-03-20[PATCH] Filter rule comparatorsDustin Kirkland
Currently, audit only supports the "=" and "!=" operators in the -F filter rules. This patch reworks the support for "=" and "!=", and adds support for ">", ">=", "<", and "<=". This turned out to be a pretty clean, and simply process. I ended up using the high order bits of the "field", as suggested by Steve and Amy. This allowed for no changes whatsoever to the netlink communications. See the documentation within the patch in the include/linux/audit.h area, where there is a table that explains the reasoning of the bitmask assignments clearly. The patch adds a new function, audit_comparator(left, op, right). This function will perform the specified comparison (op, which defaults to "==" for backward compatibility) between two values (left and right). If the negate bit is on, it will negate whatever that result was. This value is returned.

2005-05-06The attached patch addresses the problem with getting the audit daemon Steve Grubb
shutdown credential information. It creates a new message type AUDIT_TERM_INFO, which is used by the audit daemon to query who issued the shutdown. It requires the placement of a hook function that gathers the information. The hook is after the DAC & MAC checks and before the function returns. Racing threads could overwrite the uid & pid - but they would have to be root and have policy that allows signalling the audit daemon. That should be a manageable risk. The userspace component will be released later in audit 0.7.2. When it receives the TERM signal, it queries the kernel for shutdown information. When it receives it, it writes the message and exits. The message looks like this: type=DAEMON msg=auditd(1114551182.000) auditd normal halt, sending pid=2650 uid=525, auditd pid=1685 Signed-off-by: Steve Grubb <sgrubb@redhat.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
