The audit entry filter has been long deprecated with userspace support
finally removed in audit-v2.6.7 and plans to remove kernel support have
existed since kernel-v2.6.31.
Remove it.
Since removing the audit entry filter, test for early return before
setting up any context state.
Passes audit-testsuite.

A bug was introduced in 8fae47705685fcaa75a1fe4c8c3e18300a702979
("audit: add support for session ID user filter")
See: https://github.com/linux-audit/audit-kernel/issues/4
When setting a session ID filter, the session ID filter field overwrote
the quick pointer reference to the arch field, potentially causing the
arch field to be misinterpreted.
Passes audit-testsuite.

Tracefs or debugfs were causing hundreds to thousands of PATH records to
be associated with the init_module and finit_module SYSCALL records on a
few modules when the following rule was in place for startup:
-a always,exit -F arch=x86_64 -S init_module -F key=mod-load
Provide a method to ignore these large number of PATH records from
overwhelming the logs if they are not of interest. Introduce a new
filter list "AUDIT_FILTER_FS", with a new field type AUDIT_FSTYPE,
which keys off the filesystem 4-octet hexadecimal magic identifier to
filter specific filesystem PATH records.
An example rule would look like:
-a never,filesystem -F fstype=0x74726163 -F key=ignore_tracefs
-a never,filesystem -F fstype=0x64626720 -F key=ignore_debugfs
Arguably the better way to address this issue is to disable tracefs and
debugfs on boot from production systems.

RFE: add additional fields for use in audit filter exclude rules
https://github.com/linux-audit/audit-kernel/issues/5
Re-factor and combine audit_filter_type() with audit_filter_user() to
use audit_filter_user_rules() to enable the exclude filter to
additionally filter on PID, UID, GID, AUID, LOGINUID_SET, SUBJ_*.
The process of combining the similar audit_filter_user() and
audit_filter_type() functions, required inverting the meaning and
including the ALWAYS action of the latter.
Include audit_filter_user_rules() into audit_filter(), removing
unneeded logic in the process.

This adds the ability audit the actions of a not-yet-running process.
This patch implements the ability to filter on the executable path. Instead of
just hard coding the ino and dev of the executable we care about at the moment
the rule is inserted into the kernel, use the new audit_fsnotify
infrastructure to manage this dynamically. This means that if the filename
does not yet exist but the containing directory does, or if the inode in
question is unlinked and creat'd (aka updated) the rule will just continue to
work. If the containing directory is moved or deleted or the filesystem is
unmounted, the rule is deleted automatically. A future enhancement would be to
have the rule survive across directory disruptions.
This is a heavily modified version of a patch originally submitted by Eric
Paris with some ideas from Peter Moody.

This is to be used to audit by executable path rules, but audit watches should
be able to share this code eventually.
At the moment the audit watch code is a lot more complex. That code only
creates one fsnotify watch per parent directory. That 'audit_parent' in
turn has a list of 'audit_watches' which contain the name, ino, dev of
the specific object we care about. This just creates one fsnotify watch
per object we care about. So if you watch 100 inodes in /etc this code
will create 100 fsnotify watches on /etc. The audit_watch code will
instead create 1 fsnotify watch on /etc (the audit_parent) and then 100
individual watches chained from that fsnotify mark.
We should be able to convert the audit_watch code to do one fsnotify
mark per watch and simplify things/remove a whole lot of code. After
that conversion we should be able to convert the audit_fsnotify code to
support that hierarchy if the optimization is necessary.
Move the access to the entry for audit_match_signal() to the beginning of
the audit_del_rule() function in case the entry found is the same one passed
in. This will enable it to be used by audit_autoremove_mark_rule(),
kill_rules() and audit_remove_parent_watches().

The patch simply removes an old, unused field from the audit_krule

a proper overhaul of the audit pathname code and removed the nasty
getname()/putname() hacks for audit, you should see those patches in

Pull audit fixes from Paul Moore:
"Four patches to fix various problems with the audit subsystem, all are
fairly small and straightforward.
One patch fixes a problem where we weren't using the correct gfp
allocation flags (GFP_KERNEL regardless of context, oops), one patch

while), one patch fixes a problem where we weren't recording pathnames
correctly, and one fixes a problem with PID based filters.
In general I don't think there is anything controversial with this
patchset, and it fixes some rather unfortunate bugs; the allocation
flag one can be particularly scary looking for users"

A regression was caused by commit 780a7654cee8:
audit: Make testing for a valid loginuid explicit.
(which in turn attempted to fix a regression caused by e1760bd)
When audit_krule_to_data() fills in the rules to get a listing, there was a
missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.
This broke userspace by not returning the same information that was sent and
expected.
The rule:
auditctl -a exit,never -F auid=-1
gives:
auditctl -l
LIST_RULES: exit,never f24=0 syscall=all
when it should give:
LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all
Tag it so that it is reported the same way it was set. Create a new
private flags audit_krule field (pflags) to store it that won't interact with
the public one from the API.

Commit f1dc4867 ("audit: anchor all pid references in the initial pid
namespace") introduced a find_vpid() call when adding/removing audit
rules with PID/PPID filters; unfortunately this is problematic as
find_vpid() only works if there is a task with the associated PID
alive on the system. The following commands demonstrate a simple
reproducer.
# auditctl -D
# auditctl -l
# autrace /bin/true
# auditctl -l
This patch resolves the problem by simply using the PID provided by
the user without any additional validation, e.g. no calls to check to
see if the task/PID exists.

Pull audit updates from Eric Paris:
"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...
For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.
The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"

In struct audit_netlink_list and audit_reply add a reference to the

removes a huge class of races and nasty failure modes that can occur
when attempting to relook up the callers network namespace from a pid_t
(including the caller's network namespace changing, pid wraparound, and
the pid simply not being present).

Normally, netlink ports use the PID of the userspace process as the port ID.
If the PID is already in use by a port, the kernel will allocate another port
ID to avoid conflict. Re-name all references to netlink ports from pid to

use the __u32 type, so re-type all portids accordingly.
