[PATCH] via-rhine: zero pad short packets on Rhine I ethernet cards
Fixes Rhine I cards disclosing fragments of previously transmitted frames
in new transmissions.
Before transmission, any socket buffer (skb) shorter than the ethernet
minimum length of 60 bytes was zero-padded. On Rhine I cards the data can
later be copied into an aligned transmission buffer without copying this
padding. This resulted in the transmission of the frame with the extra
bytes beyond the provided content leaking the previous contents of this
buffer on to the network.
Now zero-padding is repeated in the local aligned buffer if one is used.
Following a suggestion from the via-rhine maintainer, no attempt is made
here to avoid the duplicated effort of padding the skb if it is known that
an aligned buffer will definitely be used. This is to make the change
"obviously correct" and allow it to be applied to a stable kernel if
necessary. There is no change to the flow of control and the changes are
only to the Rhine I code path.
The patch has run on an in-service Rhine-I host without incident. Frames
shorter than 60 bytes are now correctly zero-padded when captured on a
separate host. I see no unusual stats reported by ifconfig, and no unusual
log messages.

The SET_NETDEV_DEV has to be done before a call to register_netdev. With

struct xt_standard_target
{
struct xt_entry_target target;

};
xt_entry_target contains a pointer, so when compiled for 64 bit the
structure gets an extra 4 byte of padding at the end. On 32 bit
architectures where iptables aligns to 8 byte it will also have 4
byte padding at the end because it is only 36 bytes large.
The compat_ipt_standard_fn in the kernel adjusts the offsets by
which will always result in 4, even if the structure from userspace
was already padded to a multiple of 8. On x86 this works out by
accident because userspace only aligns to 4, on all other
architectures this is broken and causes incorrect adjustments to
the size and following offsets.

The PC Speaker driver's ->probe() routine doesn't even get called in the

to explictly add a "pcspkr" platform device in order for the driver core to
call the ->probe() routine. arch/i386/kernel/setup.c unconditionally adds
a "pcspkr" device, but the x86_64 kernel has no code at all related to the

[PATCH] page migration: Fix fallback behavior for dirty pages
Currently we check PageDirty() in order to make the decision to swap out

ptes pointing to the page. We need to first unmap the ptes before checking
for PageDirty(). If unmap is successful then the page count of the page
will also be decreased so that pageout() works properly.
This is a fix necessary for 2.6.17. Without this fix we may migrate dirty
pages for filesystems without migration functions. Filesystems may keep
pointers to dirty pages. Migration of dirty pages can result in the
filesystem keeping pointers to freed pages.
Unmapping is currently not be separated out from removing all the
references to a page and moving the mapping. Therefore try_to_unmap will
be called again in migrate_page() if the writeout is successful. However,
it wont do anything since the ptes are already removed.
The coming updates to the page migration code will restructure the code
so that this is no longer necessary.

USER_OBJS but are compiled as such.
I've also verified that unprofile didn't work in the current form, because we
set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong),
which is normally used by c_flags, but we also override c_flags for all
USER_OBJS, and there we don't call unprofile.
Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ.
We need to set c_flags (which is not a public Kbuild API) to clear a lot of
compilation flags like -nostdinc which Kbuild forces on everything.

building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses

[PATCH] Audit Filter Performance
While testing the watch performance, I noticed that selinux_task_ctxid()
was creeping into the results more than it should. Investigation showed
that the function call was being called whether it was needed or not. The
below patch fixes this.

[PATCH] Rework of IPC auditing
1) The audit_ipc_perms() function has been split into two different
functions:
- audit_ipc_obj()
- audit_ipc_set_perm()
There's a key shift here... The audit_ipc_obj() collects the uid, gid,
mode, and SElinux context label of the current ipc object. This
audit_ipc_obj() hook is now found in several places. Most notably, it
is hooked in ipcperms(), which is called in various places around the
ipc code permforming a MAC check. Additionally there are several places
where *checkid() is used to validate that an operation is being
performed on a valid object while not necessarily having a nearby
ipcperms() call. In these locations, audit_ipc_obj() is called to
ensure that the information is captured by the audit system.
The audit_set_new_perm() function is called any time the permissions on
the ipc object changes. In this case, the NEW permissions are recorded
(and note that an audit_ipc_obj() call exists just a few lines before
each instance).
2) Support for an AUDIT_IPC_SET_PERM audit message type. This allows
for separate auxiliary audit records for normal operations on an IPC
object and permissions changes. Note that the same struct
audit_aux_data_ipcctl is used and populated, however there are separate
audit_log_format statements based on the type of the message. Finally,
the AUDIT_IPC block of code in audit_free_aux() was extended to handle
aux messages of this new type. No more mem leaks I hope ;-)

[PATCH] support for context based audit filtering, part 2
This patch provides the ability to filter audit messages based on the
elements of the process' SELinux context (user, role, type, mls sensitivity,
and mls clearance). It uses the new interfaces from selinux to opaquely
store information related to the selinux context and to filter based on that
information. It also uses the callback mechanism provided by selinux to
refresh the information when a new policy is loaded.

[PATCH] support for context based audit filtering
The following patch provides selinux interfaces that will allow the audit
system to perform filtering based on the process context (user, role, type,
sensitivity, and clearance). These interfaces will allow the selinux
module to perform efficient matches based on lower level selinux constructs,
rather than relying on context retrievals and string comparisons within
the audit module. It also allows for dominance checks on the mls portion
of the contexts that are impossible with only string comparisons.

At that point dst is still the xfrm_dst for the current SA which
represents an internal flow as far as the IPsec tunnel is concerned.
Since the IP ID is going to sit on the outside of the encapsulated
