[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.

[NETFILTER] x_tables: fix compat related crash on non-x86

When iptables userspace adds an ipt_standard_target, it calculates the size
of the entire entry as:

sizeof(struct ipt_entry) + XT_ALIGN(sizeof(struct ipt_standard_target))

ipt_standard_target looks like this:

  struct xt_standard_target
  {
        struct xt_entry_target target;
        int verdict;
  };

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

  sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target),

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.

[PATCH] uml: cleanup unprofile expression and build infrastructure

*) Rather than duplicate in various buggy ways the application of
   CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files),
   centralize it in Makefile.rules.  UNPROFILE_OBJS mustn't be listed in
   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.

*) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when
   building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses
   CFLAGS_anObj.o, like done by Kbuild.

*) Make c_flags apply to all targets having the same basename, rather than
   listing .s, .i, .lst and .o, with the use (which I tested) of

$(USER_OBJS:.o=.%): c_flags = ...

and of

 -      $(obj)/unmap.c: _c_flags = ...
 +      $(obj)/unmap.%: _c_flags = ...

[PATCH] pipe: introduce ->pin() buffer operation

The ->map() function is really expensive on highmem machines right now,
since it has to use the slower kmap() instead of kmap_atomic(). Splice
rarely needs to access the virtual address of a page, so it's a waste
of time doing it.

Introduce ->pin() to take over the responsibility of making sure the

Steve Grubb [Sun, 2 Apr 2006 21:07:33 +0000 (17:07 -0400)]
[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 ;-)

[IPV6]: Fix race in route selection.

We eliminated rt6_dflt_lock (to protect default router pointer)
at 2.6.17-rc1, and introduced rt6_select() for general router selection.
The function is called in the context of rt6_lock read-lock held,
but this means, we have some race conditions when we do round-robin.

[IPSEC]: Fix IP ID selection

I was looking through the xfrm input/output code in order to abstract
out the address family specific encapsulation/decapsulation code.  During
that process I found this bug in the IP ID selection code in xfrm4_output.c.

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
packet, we obviously want the external flow which is just dst->child.
