2013-11-05audit: call audit_bprm() only once to add AUDIT_EXECVE informationRichard Guy Briggs
Move the audit_bprm() call from search_binary_handler() to exec_binprm(). This allows us to get rid of the mm member of struct audit_aux_data_execve since bprm->mm will equal current->mm. This also mitigates the issue that ->argc could be modified by the load_binary() call in search_binary_handler(). audit_bprm() was being called to add an AUDIT_EXECVE record to the audit context every time search_binary_handler() was recursively called. Only one reference is necessary.

2013-07-09audit: fix mq_open and mq_unlink to add the MQ root as a hidden parent ↵Jeff Layton
audit_names record The old audit PATH records for mq_open looked like this: type=PATH msg=audit(1366282323.982:869): item=1 name=(null) inode=6777 dev=00:0c mode=041777 ouid=0 ogid=0 rdev=00:00 obj=system_u:object_r:tmpfs_t:s15:c0.c1023 type=PATH msg=audit(1366282323.982:869): item=0 name="test_mq" inode=26732 dev=00:0c mode=0100700 ouid=0 ogid=0 rdev=00:00 obj=staff_u:object_r:user_tmpfs_t:s15:c0.c1023 ...with the audit related changes that went into 3.7, they now look like this: type=PATH msg=audit(1366282236.776:3606): item=2 name=(null) inode=66655 dev=00:0c mode=0100700 ouid=0 ogid=0 rdev=00:00 obj=staff_u:object_r:user_tmpfs_t:s15:c0.c1023 type=PATH msg=audit(1366282236.776:3606): item=1 name=(null) inode=6926 dev=00:0c mode=041777 ouid=0 ogid=0 rdev=00:00 obj=system_u:object_r:tmpfs_t:s15:c0.c1023 type=PATH msg=audit(1366282236.776:3606): item=0 name="test_mq" Both of these look wrong to me. As Steve Grubb pointed out: "What we need is 1 PATH record that identifies the MQ. The other PATH records probably should not be there." Fix it to record the mq root as a parent, and flag it such that it should be hidden from view when the names are logged, since the root of the mq filesystem isn't terribly interesting. With this change, we get a single PATH record that looks more like this: type=PATH msg=audit(1368021604.836:484): item=0 name="test_mq" inode=16914 dev=00:0c mode=0100644 ouid=0 ogid=0 rdev=00:00 obj=unconfined_u:object_r:user_tmpfs_t:s0 In order to do this, a new audit_inode_parent_hidden() function is added. If we do it this way, then we avoid having the existing callers of audit_inode needing to do any sort of flag conversion if auditing is inactive.

2013-04-30audit: fix event coverage of AUDIT_ANOM_LINKEric Paris
The userspace audit tools didn't like the existing formatting of the AUDIT_ANOM_LINK event. It needed to be expanded to emit an AUDIT_PATH event as well, so this implements the change. The bulk of the patch is moving code out of auditsc.c into audit.c and audit.h for general use. It expands audit_log_name to include an optional "struct path" argument for the simple case of just needing to report a pathname. This also makes audit_log_task_info available when syscall auditing is not enabled, since it is needed in either case for process details.

2012-10-12audit: set the name_len in audit_inode for parent lookupsJeff Layton
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 <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-09-18userns: Convert audit to work with user namespaces enabledEric W. Biederman
- 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.

2012-09-18audit: Add typespecific uid and gid comparatorsEric W. Biederman
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.

2007-10-21[PATCH] audit: watching subtreesAl Viro
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.

2007-07-16Audit: add TTY input auditingMiloslav Trmac
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.

2006-07-01[PATCH] add rule filterkeyAmy Griffis
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: Amy Griffis <amy.griffis@hpd.com>

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] fix deadlocks in AUDIT_LIST/AUDIT_LIST_RULESAl Viro
We should not send a pile of replies while holding audit_netlink_mutex since we hold the same mutex when we receive commands. As the result, we can get blocked while sending and sit there holding the mutex while auditctl is unable to send the next command and get around to receiving what we'd sent. Solution: create skb and put them into a queue instead of sending; once we are done, send what we've got on the list. The former can be done synchronously while we are handling AUDIT_LIST or AUDIT_LIST_RULES; we are holding audit_netlink_mutex at that point.
