[PATCH] more raw driver minor numbers
From: Badari Pulavarty <pbadari@us.ibm.com>
Since we have larger dev_t now, here is the patch to support large
number of RAW devices. The userlevel command "raw" also needs changes to
use this support - which in turn needs new glibc.
Witht he EXPORT_SYMBOL cleanups, net/netsyms.c has been removed. The
kernel-api DocBook docs still refer to this file, and because this file
is gone, "make htmldocs" and similar fails.
This just removes the reference and so fixes this docbook problem.
drivers/char/misc.c was changed to use the common list macros instead of
its own list code. The first open does load the module and increment
its use count, but a bug causes a failure to be reported anyway. This
causes an error return to user-space where there is none, and makes the
module non-unloadable.

[PATCH] USB: fix drivers/usb/host/uhci-debug.c warning when !CONFIG_PROC_FS.
I'm getting this when compiling USB with all options enabled:
drivers/usb/host/uhci-debug.c:417: warning: `uhci_sprint_schedule' defined but not used
my suggestion is to put under the #ifdef/#endif the functions which are
only used by the proc ones too. If one of them become necessary when
CONFIG_PROC_FS=n, the #ifdef/#endif for that function can be removed:
ide_pci_setup_ports() from setup-pci.c checks if port is disabled, if so
d->init_setup_dma() and d->init_hwif() won't be called. There is no need
to check it once again inside init_hwif_amd74xx(), init_dma_amd74xx()
and amd74xx_tune_drive() (hwif->tuneproc will be NULL for disabled port).
Therefore remove amd_enabled variable and now unnecessary init_dma_amd74xx().
Also do not set .init_{iops, dma} to NULL in amd74xx.h (amd74xx_chipsets[]
is declared static). Bump driver's version number to reflect changes.

[PATCH] fix vsyscall page in core dumps
My change to core dumps that was included with the vsyscall DSO
implementation had a bug (braino on my part). Core dumps don't include the
full page of the vsyscall DSO, and so don't accurately represent the whole
memory image of the process. This patch fixes it. I have tested it on
x86, but not tested the same change to 32-bit core dumps on AMD64 (haven't
even compiled on AMD64).
I've also included the corresponding change for the IA64 code that was
copied blindly from the x86 vsyscall implementation, which looks like more
change than it is since I preserved the formatting of the copied code
instead of arbitrarily diddling it along with the trivial symbol name
changes. I haven't compiled or tested on ia64.

[NETFILTER]: LOCAL_OUT NAT fix, part 2.
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.
[NETFILTER]: Make conntrack timeouts become sysctls.
This patch introduces the /proc/sys/net/ipv4/netfilter/ directory for=20

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.

[NETFILTER]: LOCAL_OUT NAT fix.
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.

[PATCH] Improve sget() performance
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).

[PATCH] /proc/PID/auxv file and NT_AUXV core note
From: Roland McGrath <roland@redhat.com>
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.

A nameidata is already passed (although sometimes NULL) to

pathname information in audit messages when a nameidata structure was
supplied.
