Currently this call is (ab)used similar to devinet one - it
registers sysctls for devices and for the "default" confs, while
the "all" sysctls are registered separately. But unlike its
devinet brother, the passed inet6_device is needed.

The fix is to make a __addrconf_sysctl_register(), which registers
sysctls for all "devices" we need, including "default" and "all" :)

The original addrconf_sysctl_register() calls the introduced
function, passing the inet6_device, device name and ifindex (to
be used as procname and ctl_name) into it.

Thanks to Herbert again for pointing out, that we can shrink the
argument list to 1 :)

The path is also located on the stack and is prepared
inside the function. This time, the call to the registering
function is guarded with the RTNL lock, but I decided
to keep it on the stack not to litter the devinet.c file
with unneeded names and to make it look similar to the
neighbors code.

This is also intended to help us with the net namespaces
and saves the vmlinux size as well - this time by more

Besides, the inet_device is passed to this function, but it is
not needed there at all - just the device name and ifindex are

Thanks to Herbert, who noticed, that this call doesn't even

we can take from the in_device itself.

The scan code in mac80211 makes the software scan assumption in various
places. For example, we stop the Tx queue during a software scan so that
all the Tx packets will be queued by the stack. We also drop frames not
related to scan in the software scan process. But these are not true for
hardware scan.

Some wireless hardwares (for example iwl3945/4965) has the ability to
perform the whole scan process by hardware and/or firmware. The hardware
scan is relative powerful in that it tries to maintain normal network
traffic while doing a scan in the background. Some drivers (i.e iwlwifi)
do provide a way to tune the hardware scan parameters (for example if the
STA is associated, what's the max time could the STA leave from the
associated channel, how long the scans get suspended after returning to
the service channel, etc). But basically this is transparent to the
stack. mac80211 should not stop Tx queues or drop Rx packets during a
hardware scan.

This patch resolves the above problem by spliting the current scan
indicator local->sta_scanning into local->sta_sw_scanning and
local->sta_hw_scanning. It then changes the scan related code to be aware
of hardware scan or software scan in various places. With this patch,
iwlwifi performs much better in the scan-while-associated condition and
disable_hw_scan=1 should never be required.

The appropriate path is prepared right inside this function. It
is prepared similar to how the ctl tables were.

Since the path is modified, it is put on the stack, to avoid
possible races with multiple calls to neigh_sysctl_register() : it
is called by protocols and I didn't find any protection in this
case. Did I overlooked the rtnl lock?.

The stack growth of the neigh_sysctl_register() is 40 bytes. I
believe this is OK, since this is not that much and this function
is not called with the deep stack (device/protocols register).

The device's name is stored on the template to free it later.

This will help with the net namespaces, as each namespace should
have its own set of these ctls.

Besides, this saves ~350 bytes from the neigh template :)

Currently the netmask/prefix-length of an IPsec SPD entry is not included in
any of the SPD related audit messages.  This can cause a problem when the
audit log is examined as the netmask/prefix-length is vital in determining
what network traffic is affected by a particular SPD entry.  This patch fixes
this problem by adding two additional fields, "src_prefixlen" and
"dst_prefixlen", to the SPD audit messages to indicate the source and
destination netmasks.  These new fields are only included in the audit message
when the netmask/prefix-length is less than the address length, i.e. the SPD
entry applies to a network address and not a host address.

Example audit message:

 type=UNKNOWN[1415] msg=audit(1196105849.752:25): auid=0 \
   subj=root:system_r:unconfined_t:s0-s0:c0.c1023 op=SPD-add res=1 \
   src=192.168.0.0 src_prefixlen=24 dst=192.168.1.0 dst_prefixlen=24

In addition, this patch also fixes a few other things in the
xfrm_audit_common_policyinfo() function.  The IPv4 string formatting was
converted to use the standard NIPQUAD_FMT constant, the memcpy() was removed
from the IPv6 code path and replaced with a typecast (the memcpy() was acting
as a slow, implicit typecast anyway), and two local variables were created to
make referencing the XFRM security context and selector information cleaner.

This patch implements the basic infrastructure for per namespace sysctls.

A list of lists of sysctl headers is added, allowing each namespace to have
it's own list of sysctl headers.

Each list of sysctl headers has a lookup function to find the first
sysctl header in the list, allowing the lists to have a per namespace
instance.

register_sysct_root is added to tell sysctl.c about additional
lists of sysctl_headers.  As all of the users are expected to be in
kernel no unregister function is provided.

sysctl_head_next is updated to walk through the list of lists.

__register_sysctl_paths is added to add a new sysctl table on
a non-default sysctl list.

The only intrusive part of this patch is propagating the information
to decided which list of sysctls to use for sysctl_check_table.

There are a number of modules that register a sysctl table
somewhere deeply nested in the sysctl hierarchy, such as
fs/nfs, fs/xfs, dev/cdrom, etc.

They all specify several dummy ctl_tables for the path name.
This patch implements register_sysctl_path that takes
an additional path name, and makes up dummy sysctl nodes
for each component.

This patch was originally written by Olaf Kirch and
brought to my attention and reworked some by Olaf Hering.
I have changed a few additional things so the bugs are mine.

After converting all of the easy callers Olaf Hering observed
allyesconfig ARCH=i386, the patch reduces the final binary size by 9369 bytes.

.text +897
.data -7008

   text    data     bss     dec     hex filename

So this change is both a space savings and a code simplification.

This adds the necessary state transitions for the two forms of passive-close

 * PASSIVE_CLOSE    - which is entered when a host   receives a Close;
 * PASSIVE_CLOSEREQ - which is entered when a client receives a CloseReq.

Here is a detailed account of what the patch does in each state.

1) Receiving CloseReq

  The pseudo-code in 8.5 says:

     Step 13: Process CloseReq
          If P.type == CloseReq and S.state < CLOSEREQ,
              Generate Close
              S.state := CLOSING
              Set CLOSING timer.

  This means we need to address what to do in CLOSED, LISTEN, REQUEST, RESPOND, PARTOPEN, and OPEN.

   * CLOSED:         silently ignore - it may be a late or duplicate CloseReq;
   * LISTEN/RESPOND: will not appear, since Step 7 is performed first (we know we are the client);
   * REQUEST:        perform Step 13 directly (no need to enqueue packet);
   * OPEN/PARTOPEN:  enter PASSIVE_CLOSEREQ so that the application has a chance to process unread data.

  When already in PASSIVE_CLOSEREQ, no second CloseReq is enqueued. In any other state, the CloseReq is ignored.
  I think that this offers some robustness against rare and pathological cases: e.g. a simultaneous close where
  the client sends a Close and the server a CloseReq. The client will then be retransmitting its Close until it
  gets the Reset, so ignoring the CloseReq while in state CLOSING is sane.

2) Receiving Close

  The code below from 8.5 is unconditional.

     Step 14: Process Close
          If P.type == Close,
              Generate Reset(Closed)
              Tear down connection
              Drop packet and return

  Thus we need to consider all states:
   * CLOSED:           silently ignore, since this can happen when a retransmitted or late Close arrives;
   * LISTEN:           dccp_rcv_state_process() will generate a Reset ("No Connection");
   * REQUEST:          perform Step 14 directly (no need to enqueue packet);
   * RESPOND:          dccp_check_req() will generate a Reset ("Packet Error") -- left it at that;
   * OPEN/PARTOPEN:    enter PASSIVE_CLOSE so that application has a chance to process unread data;
   * CLOSEREQ:         server performed active-close -- perform Step 14;
   * CLOSING:          simultaneous-close: use a tie-breaker to avoid message ping-pong (see comment);
   * PASSIVE_CLOSEREQ: ignore - the peer has a bug (sending first a CloseReq and now a Close);
   * TIMEWAIT:         packet is ignored.

   Note that the condition of receiving a packet in state CLOSED here is different from the condition "there
   is no socket for such a connection": the socket still exists, but its state indicates it is unusable.

   Last, dccp_finish_passive_close sets either DCCP_CLOSED or DCCP_CLOSING = TCP_CLOSING, so that
