Patch from Lennert Buytenhek
Add a PLAT8250_DEV_PLATFORM2, and convert the two ixdp2x01 CPLD serial
ports to use platform serial devices with ids PLAT8250_DEV_PLATFORM[12].
(The on-chip xscale UART is PLAT8250_DEV_PLATFORM, id #0.)

Patch from Nicolas Pitre
Quoting RMK:
|pte_write() just says that the page _may_ be writable. It doesn't say
|that the MMU is programmed to allow writes. If pte_dirty() doesn't
|return true, that means that the page is _not_ writable from userspace.
|If you write to it from kernel mode (without using put_user) you'll
|bypass the MMU read-only protection and may end up writing to a page
|owned by two separate processes.

Read the processor ID at boot, and save it in "processor_id" as we
did before. Later, when we re-parse the CPU type in the setup.c code,
re-use the value stored in "processor_id".

Hi,
This is a trivial patch that enables the possibility of using some auditing
functions within loadable kernel modules (ie. inside a Linux Security Module).
_
Make the audit_log_start, audit_log_end, audit_format and audit_log
interfaces available to Loadable Kernel Modules, thus making possible
the usage of the audit framework inside LSMs, etc.

Darrel Goeddel initiated a discussion on IRC regarding the possibility
of audit_comparator() returning -EINVAL signaling an invalid operator.
It is possible when creating the rule to assure that the operator is one
of the 6 sane values. Here's a snip from include/linux/audit.h Note
that 0 (nonsense) and 7 (all operators) are not valid values for an
operator.
...
/* These are the supported operators.
* 4 2 1
* = > <
* -------
* 0 0 0 0 nonsense
* 0 0 1 1 <
* 0 1 0 2 >
* 0 1 1 3 !=
* 1 0 0 4 =
* 1 0 1 5 <=
* 1 1 0 6 >=
* 1 1 1 7 all operators
*/
...
Furthermore, prior to adding these extended operators, flagging the
AUDIT_NEGATE bit implied !=, and otherwise == was assumed.
The following code forces the operator to be != if the AUDIT_NEGATE bit
was flipped on. And if no operator was specified, == is assumed. The
only invalid condition is if the AUDIT_NEGATE bit is off and all of the
AUDIT_EQUAL, AUDIT_LESS_THAN, and AUDIT_GREATER_THAN bits are
on--clearly a nonsensical operator.
Now that this is handled at rule insertion time, the default -EINVAL
return of audit_comparator() is eliminated such that the function can
only return 1 or 0.
If this is acceptable, let's get this applied to the current tree.

Hi,
When a network interface goes into promiscuous mode, its an important security
issue. The attached patch is intended to capture that action and send an
event to the audit system.
The patch carves out a new block of numbers for kernel detected anomalies.
These are events that may indicate suspicious activity. Other examples of
potential kernel anomalies would be: exceeding disk quota, rlimit violations,
changes to syscall entry table.

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.

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()

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).
