| | * [PATCH] ARM SMP: Fix vector entryRussell King2005-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current vector entry system does not allow for SMP. In order to work around this, we need to eliminate our reliance on the fixed save areas, which breaks the way we enable alignment traps. This patch changes the way we handle the save areas such that we can have one per CPU. Signed-off-by: Russell King <rmk@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current vector entry system does not allow for SMP. In order to work around this, we need to eliminate our reliance on the fixed save areas, which breaks the way we enable alignment traps.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I cunningly put the audit call immediately after the copy_from_user().... but used the _userspace_ copy of the args still. Let's not do that. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While they were all just simple blobs it made sense to just free them as we walked through and logged them. Now that there are pointers to other objects which need refcounting, we might as well revert to _only_ logging them in audit_log_exit(), and put the code to free them properly in only one place -- in audit_free_aux().

| * | | | AUDIT: Fix remaining cases of direct logging of untrusted strings by avc_auditStephen Smalley2005-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per Steve Grubb's observation that there are some remaining cases where avc_audit() directly logs untrusted strings without escaping them, here is a patch that changes avc_audit() to use audit_log_untrustedstring() or audit_log_hex() as appropriate. Note that d_name.name is nul- terminated by d_alloc(), and that sun_path is nul-terminated by unix_mkname(), so it is not necessary for the AVC to create nul- terminated copies or to alter audit_log_untrustedstring to take a length argument. In the case of an abstract name, we use audit_log_hex() with an explicit length. Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We turned this all off because the 'exe=' was causing deadlocks on dcache_lock.

This is fixed by not calling skb_put with bogus len values. * audit_log_hex was a loop that called audit_log_vformat with %02X for each character. This is very inefficient since conversion from unsigned character to Ascii representation is essentially masking, shifting, and byte lookups. Also, the length of the converted string is well known - it's twice the original. Fixed by rewriting the function. * audit_log_untrustedstring had no comments. This makes it hard for someone to understand what the string format will be. * audit_log_d_path was never fixed to use untrustedstring. This could mess up user space parsers. This was fixed to make a temp buffer, call d_path, and log temp buffer using untrustedstring. From: Steve Grubb <sgrubb@redhat.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

Convert audit_log to wrapper around audit_log_type. Could have converted all audit_log callers directly, but common case is default of type AUDIT_KERNEL and pid 0. Update audit_log_start to take type and pid values when creating a new audit_buffer. Move sequences that did audit_log_start, audit_log_format, audit_set_type, audit_log_end, to simply call audit_log_type directly. This obsoletes audit_set_type and audit_set_pid, so remove them.

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>
