[PATCH] audit: restore order of tty and ses fields in log output
by Richard Guy Briggs
When being refactored from audit_log_start() to audit_log_task_info(), in
commit e23eb920 the tty and ses fields in the log output got transposed.
Restore to original order to avoid breaking search tools.

Re: [PATCH RFC 7/8] audit: report namespace information along with USER events
by Eric W. Biederman
Aristeu Rozanski <arozansk(a)redhat.com> writes:

I am not comfortable with using the inode numbers this way. It does not
pass the test of can I migrate a container and still have this work
test. Any kind of kernel assigned name for namespaces fails that test.
I also don't like that you don't include the procfs device number. An
inode number means nothing without knowing which filesystem you are
referring to.
It may never happen but I reserve the right to have the inode numbers
for namespaces to show up differently in different instances of procfs.
Beyond that I think this usage is possibly buggy by using two audit
records for one event.

[PATCH] audit: printk USER_AVC messages when audit isn't enabled
by Tyler Hicks
When the audit=1 kernel parameter is absent and auditd is not running,
AUDIT_USER_AVC messages are being silently discarded.
AUDIT_USER_AVC messages should be sent to userspace using printk(), as
mentioned in the commit message of
4a4cd633b575609b741a1de7837223a2d9e1c34c ("AUDIT: Optimise the
audit-disabled case for discarding user messages").
When audit_enabled is 0, audit_receive_msg() discards all user messages
except for AUDIT_USER_AVC messages. However, audit_log_common_recv_msg()
refuses to allocate an audit_buffer if audit_enabled is 0. The fix is to
special case AUDIT_USER_AVC messages in both functions.

It looks like commit 50397bd1e471391d27f64efad9271459c913de87 ("[AUDIT] clean
up audit_receive_msg()") introduced this bug, so I think that this patch should
also get the tag:

Al and Eric, I'll leave that up to you two.
Here's my test matrix showing where messages end up as a result of a call to
libaudit's audit_log_user_avc_message():

[GIT PULL] audit subsystem for 3.14
by Eric Paris
Linus,
Please consider pulling the following audit changes. Again we stayed
pretty well contained inside the audit system. Venturing out was fixing
a couple of function prototypes which were inconsistent (didn't hurt
anything, but we used the same value as an int, uint, u32, and I think
even a long in a couple of places). We also made a couple of minor
changes to when a couple of LSMs called the audit system. We hoped to
add aarch64 audit support this go round, but it wasn't ready.
There is one merge issue. Take your code, then convert the prototype
for the first 4 functions changing the "u32 ses" to "unsigned int ses".
(Do not change the u32 secid)
I'm disappearing on vacation on Thursday. I should have internet
access, but it'll be spotty. If anything goes wrong please be sure to
cc rgb(a)redhat.com. He'll make fixing things his top priority.
-Eric

Suppressing logs with kernel.printk
by Aaron Lewis
Hi,
I'm trying to suppress logs from auditd with sysctl options,
So I set kernel.printk to 4 4 4 4
And modified KLOGD_OPTIONS to "-x -c 4"
Then I restarted syslogd and klogd
But I still see auditd logs piling up, anything wrong? auditd is using
kenrel.notice for sure

[PATCH] audit/userspace: add support for the parisc architecture
by Helge Deller
The patch below adds support for the parisc architecture to the audit
userspace tool.
It would be great if you could apply this patch to trunk.
I posted the corresponding Linux kernel patch to the parisc mailing list
(https://patchwork.kernel.org/patch/3046731/) and plan to push it upstream when
the merge window for Linux kernel v3.13 opens.

What is the bug
by Burn Alting
All,
Consider the following raw audit event ...
node=fedora20.swtf.dyndns.org type=CONFIG_CHANGE
msg=audit(1390028319.573:20803): auid=4294967295 ses=4294967295
subj=system_u:system_r:auditctl_t:s0 op="remove rule"
key="time-change" list=4 res=1
When the auparse library parses this event event, it does not correctly
parse the 'op' value and so both auparse_get_field_str() and
auparse_interpret_field() both return '"remove' rather than 'remove
rule'.
Now, I seem to recollect an earlier e-mail that would suggest the bug is
in kernel/auditfilter.c:audit_receive_filter() as it calls
audit_log_rule_change() with the string "add rule" or "remove rule". One
assumes we need to perhaps either
a. replace the space with a hyphen in these arguments, or
b. in kernel/auditfilter.c:audit_log_rule_change() replace the call
audit_log_string(ab, action);
with
audit_log_untrustedstring(ab, action);
If this is the case, then is there any appetite to have these bugs fixed
on the next update to the kernel audit code?
Thanks in advance
Burn
