* [PATCH] audit config lockdownSteve Grubb2007-02-17
| | | | | | | | | | | | | | | | | | The following patch adds a new mode to the audit system. It uses the audit_enabled config option to introduce the idea of audit enabled, but configuration is immutable. Any attempt to change the configuration while in this mode is audited. To change the audit rules, you'd need to reboot the machine. To use this option, you'd need a modified version of auditctl and use "-e 2". This is intended to go at the end of the audit.rules file for people that want an immutable configuration. This patch also adds "res=" to a number of configuration commands that did not have it before. Signed-off-by: Steve Grubb <sgrubb@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* [NETLINK]: Encapsulate eff_cap usage within security framework.Darrel Goeddel2006-06-29
| | | | | | | | | | | | | | | | This patch encapsulates the usage of eff_cap (in netlink_skb_params) within the security framework by extending security_netlink_recv to include a required capability parameter and converting all direct usage of eff_caps outside of the lsm modules to use the interface. It also updates the SELinux implementation of the security_netlink_send and security_netlink_recv hooks to take advantage of the sid in the netlink_skb_params struct. This also enables SELinux to perform auditing of netlink capability checks. Please apply, for 2.6.18 if possible.

| | | | | | | | | | | | | | | | | | | | | | | | | When an audit event involves changes to a directory entry, include a PATH record for the directory itself.

* [PATCH] audit: path-based rulesAmy Griffis2006-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* [PATCH] minor audit updatesSerge E. Hallyn2006-06-20
| | | | | | | | | | | | | | | | | | | | | Just a few minor proposed updates. Only the last one will actually affect behavior. The rest are just misleading code. Several AUDIT_SET functions return 'old' value, but only return value <0 is checked for. So just return 0. propagate audit_set_rate_limit and audit_set_backlog_limit error values In audit_buffer_free, the audit_freelist_count was being incremented even when we discard the return buffer, so audit_freelist_count can end up wrong. This could cause the actual freelist to shrink over time, eventually threatening to degrate audit performance. Signed-off-by: Serge E.

* [PATCH] fix deadlocks in AUDIT_LIST/AUDIT_LIST_RULESAl Viro2006-06-20
| | | | | | | | | | | | | | | | 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. The latter is done asynchronously and without messing with audit_netlink_mutex. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* [PATCH] support for context based audit filtering, part 2Darrel Goeddel2006-05-01
| | | | | | | | | | | This patch provides the ability to filter audit messages based on the elements of the process' SELinux context (user, role, type, mls sensitivity, and mls clearance). It uses the new interfaces from selinux to opaquely store information related to the selinux context and to filter based on that information. It also uses the callback mechanism provided by selinux to refresh the information when a new policy is loaded. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [PATCH] Don't pass boot parameters to argv_init[]OGAWA Hirofumi2006-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The boot cmdline is parsed in parse_early_param() and parse_args(,unknown_bootoption). And __setup() is used in obsolete_checksetup(). start_kernel() -> parse_args() -> unknown_bootoption() -> obsolete_checksetup() If __setup()'s callback (->setup_func()) returns 1 in obsolete_checksetup(), obsolete_checksetup() thinks a parameter was handled. If ->setup_func() returns 0, obsolete_checksetup() tries other ->setup_func(). If all ->setup_func() that matched a parameter returns 0, a parameter is seted to argv_init[]. Then, when runing /sbin/init or init=app, argv_init[] is passed to the app. If the app doesn't ignore those arguments, it will warning and exit.

If the message type is not to be audited, return NULL very early, before doing a lot of work.

* [PATCH] EDAC: atomic scrub operationsAlan Cox2006-01-18
| | | | | | | | | | | | | | | | | EDAC requires a way to scrub memory if an ECC error is found and the chipset does not do the work automatically. That means rewriting memory locations atomically with respect to all CPUs _and_ bus masters. That means we can't use atomic_add(foo, 0) as it gets optimised for non-SMP This adds a function to include/asm-foo/atomic.h for the platforms currently supported which implements a scrub of a mapped block. It also adjusts a few other files include order where atomic.h is included before types.h as this now causes an error as atomic_scrub uses u32.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We force a rate-limit on auditable events by making them wait for space on the backlog queue. However, if auditd really is AWOL then this could potentially bring the entire system to a halt, depending on the audit rules in effect. Firstly, make sure the wait time is honoured correctly -- it's the maximum time the process should wait, rather than the time to wait _each_ time round the loop. We were getting re-woken _each_ time a packet was dequeued, and the timeout was being restarted each time. Secondly, reset the wait time after audit_panic() is called. In general this will be reset to zero, to allow progress to be made. If the system is configured to _actually_ panic on audit_panic() then that will already have happened; otherwise we know that audit records are being lost anyway. These two tunables can't be exposed via AUDIT_GET and AUDIT_SET because those aren't particularly well-designed. It probably should have been done by sysctls or sysfs anyway -- one for a later patch.

* AUDIT: Assign serial number to non-syscall messagesDavid Woodhouse2005-05-21
| | | | | | | | | | | | Move audit_serial() into audit.c and use it to generate serial numbers on messages even when there is no audit context from syscall auditing. This allows us to disambiguate audit records when more than one is generated in the same millisecond. Based on a patch by Steve Grubb after he observed the problem.
