We do though need an I-cache flush on spitfire chips when
doing a module load.

Happily this allows us to kill off flush_cache_all() from
sparc64.

Balazs Scheidler pointed out that we can fail to call ip_nat_setup_info
for local NAT, which causes the connection to be added twice. Boom.
Also move the hash table insertion into ip_nat_setup_info.

This patch introduces the /proc/sys/net/ipv4/netfilter/ directory for=20
the tuneable parameters of the conntrack engine of netfilter.

The parameters which can currently be fine-tuned (if required at all)=20
are the ip_conntrack_max, and the conntrack timeout parameters in seconds.

The default timeout value for the TCP CLOSE_WAIT state is raised to 3
days, which should cause less problems with long-lived half-closed TCP
sessions.

For the sake of compatibility with 2.4,=20
/proc/sys/net/ipv4/netfilter/ip_conntrack_max is duplicated as=20
/proc/sys/net/ipv4/ip_conntrack_max as well.

the 25_natcore-nohelper.patch (incorporated in 2.4.22) did actually make
things not better.  If a NAT rule was matched, num_manips can still be 0.
However, some helpers (like PPTP) need to _always mangle the packets,
even if there is no NAT mapping for a particular connection.
On the other hand, as soon as CONFIG_IP_NF_LOCAL_NAT was disabled,
we did end up half-mangling local (non-NAT'ed) connections.  This patch
removes the LOCAL_OUT hook from the NAT core unless CONFIG_IP_NF_NAT_LOCAL
is enabled.

This removes the remains of some debugging stuff which was never really
enabled properly - it never reported memory leaks.  Its not useful for
anyone but me. 

A proper solution involves counting all requests in flight and all
threads but we'll probably put that just into mm.

sget() is pessimistic and assumes it won't find a superblock - and as a
result it always pre-allocates a new one before even searching for an
existing entry.  If it finds an existing one, it free's the extra one it
just allocated.

Especially with /proc usage it usually _does_ find an existing
superblock, so this is all extra work.  It should allocate a new one
only if it couldn't find an old one (and re-search).

The same way as iget() does it.

This one won't cause hangs, but can trip some WARNs.

Rather than not kfree'ing the UDF data in the case of a bad inode (which
still _may_ have had the UDF data already allocated to it), make sure to
initialize the pointer to NULL properly when we're done with it.

gdb really needs some way to know the AT_SYSINFO_EHDR value for a process
being debugged or for the dead process described by a core file.  Without
this value, it can't find the information necessary to show backtraces of
threads waiting in system calls.  There are any number of ways this
information could be made available.  Here is one solution that provides
more debugging information in a clean and general fashion.

I've added access to the AT_* values passed to a process for third parties
to examine for debugging purposes.  The same data passed on the stack at
startup is made available in /proc/PID/auxv and is written in an NT_AUXV
note in core dumps.  (Both of these are consistent with what Solaris does
using the same names.)

Here are two different patches that implement the same thing differently.
The first patch uses a ref-counted data structure to copy the aux vector
and shares among forked mm's until they exec and get a new one.  The second
patch avoids the complexity of that data structure by simply expanding the
mm_struct with space to hold a copy of the data.  Both patches work
correctly; I have examined the new /proc/PID/auxv file and core dumps.

I hope you will consider including one of these patches, or at least some
way of getting at this information from the debugger.  I am certainly open
to other suggestions on implementing this feature, and to suggestions on
alternative interfaces for getting the AT_SYSINFO_EHDR value cleanly.

Remember to free the inode cache if register_filesystem() fails.

From: Rolf Eike Beer <eike-kernel@sf-tec.de>

this patch makes some ints to unsigned ints.  They are only used as loop
counters and compared to unsigned ints.  GCC 3.3 doesn't like this.  They
will never be negative anyway, so we could easily shut him up.

From: Stephen Smalley <sds@epoch.ncsc.mil>

This patch changes the security_inode_permission hook to also take a
nameidata parameter in addition to the existing inode and mask parameters. 

A nameidata is already passed (although sometimes NULL) to
fs/namei.c:permission(), and the patch changes exec_permission_lite() to
also take a nameidata parameter so that it can pass it along to the
security hook.

The patch includes corresponding changes to the SELinux module to use the
nameidata information when it is available; this allows SELinux to include
pathname information in audit messages when a nameidata structure was
supplied.

From: Stephen Smalley <sds@epoch.ncsc.mil>

This patch fixes a bug introduced by earlier code cleanups in the SELinux
convert_context code that manifests upon a policy reload that removes
previously valid security attributes.  Thanks to Magosanyi Arpad for
reporting the bug.

If other kmallocs failed after successfully allocating a "struct mtd_info",
it should be freed before returning NULL.

From: Christoph Hellwig <hch@lst.de>

It's the only abuse of proc_iops left (except the totally b0rked comx
driver).  The patch is from Al, I just forward-ported it from 2.4.

Background: struct proc_dir_entry has a struct inode_operations *proc_iops
member, it's from Linux's stoneage and used internally by procfs to assign
either the link or directory inode ops.

Unfortunately some drivers started to abuse it do do bad things like create
on lookup (that's the comx thingy which relies on unexported symbols and thus
is broken for modular builds since mid-2.3) or various ->permission tricks
(all gone by now).

After this patch is gone I have another one that kills proc_iops and just
uses a normal conditional inside procfs to assign the right one directly.
