      [PATCH] Fix IA64 success/failure indication in syscall auditing. · ee436dc4
      David Woodhouse authored 
      Original 2.6.9 patch and explanation from somewhere within HP via
bugzilla...

ia64 stores a success/failure code in r10, and the return value (normal
return, or *positive* errno) in r8. The patch also sets the exit code to
negative errno if it's a failure result for consistency with other
architectures.

      [PATCH] Miscellaneous bug and warning fixes · 7306a0b9
      Dustin Kirkland authored 
      This patch fixes a couple of bugs revealed in new features recently
added to -mm1:
* fixes warnings due to inconsistent use of const struct inode *inode
* fixes bug that prevent a kernel from booting with audit on, and SELinux off
  due to a missing function in security/dummy.c
* fixes a bug that throws spurious audit_panic() messages due to a missing
  return just before an error_path label
* some reasonable house cleaning in audit_ipc_context(),
  audit_inode_context(), and audit_log_task_context()

      [PATCH] Capture selinux subject/object context information. · 8c8570fb
      Dustin Kirkland authored 
      This patch extends existing audit records with subject/object context
information. Audit records associated with filesystem inodes, ipc, and
tasks now contain SELinux label information in the field "subj" if the
item is performing the action, or in "obj" if the item is the receiver
of an action.

These labels are collected via hooks in SELinux and appended to the
appropriate record in the audit code.

This additional information is required for Common Criteria Labeled
Security Protection Profile (LSPP).

      [PATCH] Exclude messages by message type · c8edc80c
      Dustin Kirkland authored 
          - Add a new, 5th filter called "exclude".
    - And add a new field AUDIT_MSGTYPE.
    - Define a new function audit_filter_exclude() that takes a message type
      as input and examines all rules in the filter.  It returns '1' if the
      message is to be excluded, and '0' otherwise.
    - Call the audit_filter_exclude() function near the top of
      audit_log_start() just after asserting audit_initialized.  If the
      message type is not to be audited, return NULL very early, before
      doing a lot of work.

      [PATCH] Collect more inode information during syscall processing. · 73241ccc
      Amy Griffis authored 
      This patch augments the collection of inode info during syscall
processing. It represents part of the functionality that was provided
by the auditfs patch included in RHEL4.

Specifically, it:

- Collects information for target inodes created or removed during
  syscalls.  Previous code only collects information for the target
  inode's parent.

- Adds the audit_inode() hook to syscalls that operate on a file
  descriptor (e.g. fchown), enabling audit to do inode filtering for
  these calls.

- Modifies filtering code to check audit context for either an inode #
  or a parent inode # matching a given rule.

- Modifies logging to provide inode # for both parent and child.

- Protect debug info from NULL audit_names.name.

      [PATCH] Filter rule comparators · b63862f4
      Dustin Kirkland authored 
      Currently, audit only supports the "=" and "!=" operators in the -F
filter rules.

This patch reworks the support for "=" and "!=", and adds support
for ">", ">=", "<", and "<=".

This turned out to be a pretty clean, and simply process.  I ended up
using the high order bits of the "field", as suggested by Steve and Amy.
This allowed for no changes whatsoever to the netlink communications.
See the documentation within the patch in the include/linux/audit.h
area, where there is a table that explains the reasoning of the bitmask
assignments clearly.

The patch adds a new function, audit_comparator(left, op, right).
This function will perform the specified comparison (op, which defaults
to "==" for backward compatibility) between two values (left and right).
If the negate bit is on, it will negate whatever that result was.  This
value is returned.

      [PATCH] make vm86 call audit_syscall_exit · 7e7f8a03
      Jason Baron authored 
      hi,

The motivation behind the patch below was to address messages in
/var/log/messages such as:

Jan 31 10:54:15 mets kernel: audit(:0): major=252 name_count=0: freeing
multiple contexts (1)
Jan 31 10:54:15 mets kernel: audit(:0): major=113 name_count=0: freeing
multiple contexts (2)

I can reproduce by running 'get-edid' from:
http://john.fremlin.de/programs/linux/read-edid/.

These messages come about in the log b/c the vm86 calls do not exit via
the normal system call exit paths and thus do not call
'audit_syscall_exit'. The next system call will then free the context for
itself and for the vm86 context, thus generating the above messages. This
patch addresses the issue by simply adding a call to 'audit_syscall_exit'
from the vm86 code.

Besides fixing the above error messages the patch also now allows vm86
system calls to become auditable. This is useful since strace does not
appear to properly record the return values from sys_vm86.

I think this patch is also a step in the right direction in terms of
cleaning up some core auditing code. If we can correct any other paths
that do not properly call the audit exit and entries points, then we can
also eliminate the notion of context chaining.

I've tested this patch by verifying that the log messages no longer
appear, and that the audit records for sys_vm86 appear to be correct.
Also, 'read_edid' produces itentical output.

thanks,

-Jason

      [TG3]: 40-bit DMA workaround part 2 · 4a29cc2e
      Michael Chan authored 
      The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.

For example, some 4-port card or mother board designs have 5704 behind
the 5714.

All devices behind the EPB require the 40-bit DMA workaround.

Thanks to Chris Elmquist again for reporting the problem and testing
the patch.

      [AX.25]: Fix potencial memory hole. · c7c694d1
      Ralf Baechle DL5RB authored 
      If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
(or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
through the switch statement without calling ax25_send_iframe() or any
other function that would eventually free skbn thus leaking the packet.

Fix by restricting the sysctl inferface to allow only actually supported
AX.25 dialects.

The system administration mistake needed for this to happen is rather
unlikely, so this is an uncritical hole.

Coverity #651.
