*
* See ip_input.c for original log
*
* Fixes:
* Alan Cox : Missing nonblock feature in ip_build_xmit.
* Mike Kilburn : htons() missing in ip_build_xmit.
* Bradford Johnson: Fix faulty handling of some frames when
* no route is found.
* Alexander Demenshin: Missing sk/skb free in ip_queue_xmit
* (in case if packet not accepted by
* output firewall rules)
* Mike McLagan : Routing by source
* Alexey Kuznetsov: use new route cache
* Andi Kleen: Fix broken PMTU recovery and remove
* some redundant tests.
* Vitaly E. Lavrov : Transparent proxy revived after year coma.
* Andi Kleen : Replace ip_reply with ip_send_reply.
* Andi Kleen : Split fast and slow ip_build_xmit path
* for decreased register pressure on x86
* and more readibility.
* Marc Boucher : When call_out_firewall returns FW_QUEUE,
* silently drop skb instead of failing with -EPERM.
* Detlev Wengorz : Copy protocol for fragments.
* Hirokazu Takahashi: HW checksumming for outgoing UDP
* datagrams.
* Hirokazu Takahashi: sendfile() on UDP works now.

* NET An implementation of the SOCKET network access protocol.
*
* Version: @(#)socket.c 1.1.93 18/02/95
*
* Authors: Orest Zborowski, <obz@Kodak.COM>
* Ross Biro
* Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
*
* Fixes:
* Anonymous : NOTSOCK/BADF cleanup. Error fix in
* shutdown()
* Alan Cox : verify_area() fixes
* Alan Cox : Removed DDI
* Jonathan Kamens : SOCK_DGRAM reconnect bug
* Alan Cox : Moved a load of checks to the very
* top level.
* Alan Cox : Move address structures to/from user
* mode above the protocol layers.
* Rob Janssen : Allow 0 length sends.
* Alan Cox : Asynchronous I/O support (cribbed from the
* tty drivers).
* Niibe Yutaka : Asynchronous I/O for writes (4.4BSD style)
* Jeff Uphoff : Made max number of sockets command-line
* configurable.
* Matti Aarnio : Made the number of sockets dynamic,
* to be allocated when needed, and mr.
* Uphoff's max is used as max to be
* allowed to allocate.
* Linus : Argh. removed all the socket allocation
* altogether: it's in the inode now.
* Alan Cox : Made sock_alloc()/sock_release() public
* for NetROM and future kernel nfsd type
* stuff.
* Alan Cox : sendmsg/recvmsg basics.
* Tom Dyas : Export net symbols.
* Marcin Dalecki : Fixed problems with CONFIG_NET="n".
* Alan Cox : Added thread locking to sys_* calls
* for sockets. May have errors at the
* moment.
* Kevin Buhr : Fixed the dumb errors in the above.
* Andi Kleen : Some small cleanups, optimizations,
* and fixed a copy_from_user() bug.
* Tigran Aivazian : sys_send(args) calls sys_sendto(args, NULL, 0)
* Tigran Aivazian : Made listen(2) backlog sanity checks
* protocol-independent

* INET An implementation of the TCP/IP protocol suite for the LINUX
* operating system. INET is implemented using the BSD Socket
* interface as the means of communication with the user level.
*
* Generic socket support routines. Memory allocators, socket lock/release
* handler for protocols to use and generic option handler.
*
*
* Authors: Ross Biro
* Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
* Florian La Roche, <flla@stud.uni-sb.de>
* Alan Cox, <A.Cox@swansea.ac.uk>
*
* Fixes:
* Alan Cox : Numerous verify_area() problems
* Alan Cox : Connecting on a connecting socket
* now returns an error for tcp.
* Alan Cox : sock->protocol is set correctly.
* and is not sometimes left as 0.
* Alan Cox : connect handles icmp errors on a
* connect properly. Unfortunately there
* is a restart syscall nasty there. I
* can't match BSD without hacking the C
* library. Ideas urgently sought!
* Alan Cox : Disallow bind() to addresses that are
* not ours - especially broadcast ones!!
* Alan Cox : Socket 1024 _IS_ ok for users. (fencepost)
* Alan Cox : sock_wfree/sock_rfree don't destroy sockets,
* instead they leave that for the DESTROY timer.
* Alan Cox : Clean up error flag in accept
* Alan Cox : TCP ack handling is buggy, the DESTROY timer
* was buggy. Put a remove_sock() in the handler
* for memory when we hit 0. Also altered the timer
* code. The ACK stuff can wait and needs major
* TCP layer surgery.
* Alan Cox : Fixed TCP ack bug, removed remove sock
* and fixed timer/inet_bh race.
* Alan Cox : Added zapped flag for TCP
* Alan Cox : Move kfree_skb into skbuff.c and tidied up surplus code
* Alan Cox : for new sk_buff allocations wmalloc/rmalloc now call alloc_skb
* Alan Cox : kfree_s calls now are kfree_skbmem so we can track skb resources
* Alan Cox : Supports socket option broadcast now as does udp. Packet and raw need fixing.
* Alan Cox : Added RCVBUF,SNDBUF size setting. It suddenly occurred to me how easy it was so...
* Rick Sladkey : Relaxed UDP rules for matching packets.
* C.E.Hawkins : IFF_PROMISC/SIOCGHWADDR support
* Pauline Middelink : identd support
* Alan Cox : Fixed connect() taking signals I think.
* Alan Cox : SO_LINGER supported
* Alan Cox : Error reporting fixes
* Anonymous : inet_create tidied up (sk->reuse setting)
* Alan Cox : inet sockets don't set sk->type!
* Alan Cox : Split socket option code
* Alan Cox : Callbacks
* Alan Cox : Nagle flag for Charles & Johannes stuff
* Alex : Removed restriction on inet fioctl
* Alan Cox : Splitting INET from NET core
* Alan Cox : Fixed bogus SO_TYPE handling in getsockopt()
* Adam Caldwell : Missing return in SO_DONTROUTE/SO_DEBUG code
* Alan Cox : Split IP from generic code
* Alan Cox : New kfree_skbmem()
* Alan Cox : Make SO_DEBUG superuser only.
* Alan Cox : Allow anyone to clear SO_DEBUG
* (compatibility fix)
* Alan Cox : Added optimistic memory grabbing for AF_UNIX throughput.
* Alan Cox : Allocator for a socket is settable.
* Alan Cox : SO_ERROR includes soft errors.
* Alan Cox : Allow NULL arguments on some SO_ opts
* Alan Cox : Generic socket allocation to make hooks
* easier (suggested by Craig Metz).
* Michael Pall : SO_ERROR returns positive errno again
* Steve Whitehouse: Added default destructor to free
* protocol private data.
* Steve Whitehouse: Added various other default routines
* common to several socket families.
* Chris Evans : Call suser() check last on F_SETOWN
* Jay Schulist : Added SO_ATTACH_FILTER and SO_DETACH_FILTER.
* Andi Kleen : Add sock_kmalloc()/sock_kfree_s()
* Andi Kleen : Fix write_space callback
* Chris Evans : Security fixes - signedness again
* Arnaldo C. Melo : cleanups, use skb_queue_purge

*
* Fixes:
* Alan Cox : Merged and made usable non modular (its so tiny its silly as
* a module taking up 2 pages).
* Alan Cox : Fixed bug with 1.3.18 and IPIP not working (now needs to set skb->h.iph)
* to keep ip_forward happy.
* Alan Cox : More fixes for 1.3.21, and firewall fix. Maybe this will work soon 8).
* Kai Schulte : Fixed #defines for IP_FIREWALL->FIREWALL
* David Woodhouse : Perform some basic ICMP handling.
* IPIP Routing without decapsulation.
* Carlos Picoto : GRE over IP support
* Alexey Kuznetsov: Reworked. Really, now it is truncated version of ipv4/ip_gre.c.

/* tunnel.c: an IP tunnel driver
The purpose of this driver is to provide an IP tunnel through
which you can tunnel network traffic transparently across subnets.
This was written by looking at Nick Holloway's dummy driver
Thanks for the great code!
-Sam Lantinga (slouken@cs.ucdavis.edu) 02/01/95
Minor tweaks:
Cleaned up the code a little and added some pre-1.3.0 tweaks.
dev->hard_header/hard_header_len changed to use no headers.
Comments/bracketing tweaked.
Made the tunnels use dev->name not tunnel: when error reporting.
Added tx_dropped stat
-Alan Cox (alan@lxorguk.ukuu.org.uk) 21 March 95
Reworked:
Changed to tunnel to destination gateway in addition to the
tunnel's pointopoint address
Almost completely rewritten
Note: There is currently no firewall or ICMP handling done.
-Sam Lantinga (slouken@cs.ucdavis.edu) 02/13/96

/* Things I wish I had known when writing the tunnel driver:
When the tunnel_xmit() function is called, the skb contains the
packet to be sent (plus a great deal of extra info), and dev
contains the tunnel device that _we_ are.
When we are passed a packet, we are expected to fill in the
source address with our source IP address.
What is the proper way to allocate, copy and free a buffer?
After you allocate it, it is a "0 length" chunk of memory
starting at zero. If you want to add headers to the buffer
later, you'll have to call "skb_reserve(skb, amount)" with
the amount of memory you want reserved. Then, you call
"skb_put(skb, amount)" with the amount of space you want in
the buffer. skb_put() returns a pointer to the top (#0) of
that buffer. skb->len is set to the amount of space you have
"allocated" with skb_put(). You can then write up to skb->len
bytes to that buffer. If you need more, you can call skb_put()
again with the additional amount of space you need. You can
find out how much more space you can allocate by calling
"skb_tailroom(skb)".
Now, to add header space, call "skb_push(skb, header_len)".
This creates space at the beginning of the buffer and returns
a pointer to this new space. If later you need to strip a
header from a buffer, call "skb_pull(skb, header_len)".
skb_headroom() will return how much space is left at the top
of the buffer (before the main data). Remember, this headroom
space must be reserved before the skb_put() function is called.

*
* Edited 11/10/96 (DD/MM/YY ;-) by Nicolai Langfeldt (janl@math.uio.no)
* to read /etc/passwd directly so that passwd, chsh and chfn can work on
* machines that run NIS (previously YP). Changes will not be made to
* usernames starting with +.
*
* This file is distributed with no warranty.
*
* Usage:
* 1) get a struct passwd * from getpwnam().
* You should assume a struct passwd has an infinite number of fields, so
* you should not try to create one from scratch.
* 2) edit the fields you want to edit.
* 3) call setpwnam() with the edited struct passwd.
*
* A _normal user_ program should never directly manipulate etc/passwd but
* /use getpwnam() and (family, as well as) setpwnam().
*
* But, setpwnam was made to _edit_ the password file. For use by chfn,
* chsh and passwd. _I_ _HAVE_ to read and write /etc/passwd directly. Let
* those who say nay be forever silent and think about how getpwnam (and
* family) works on a machine running YP.
*
* Added checks for failure of malloc() and removed error reporting to
* stderr, this is a library function and should not print on the screen,
* but return appropriate error codes.

*
* Authors: Ben Greear <greearb@candelatech.com>
* Please send support related email to: netdev@vger.kernel.org
* VLAN Home Page: http://www.candelatech.com/~greear/vlan.html
*
* Fixes: Mar 22 2001: Martin Bokaemper <mbokaemper@unispherenetworks.com>
* - reset skb->pkt_type on incoming packets when MAC was changed
* - see that changed MAC is saddr for outgoing packets
* Oct 20, 2001: Ard van Breeman:
* - Fix MC-list, finally.
* - Flush MC-list on VLAN destroy.

* pivot_root Semantics:
* Moves the root file system of the current process to the directory put_old,
* makes new_root as the new root file system of the current process, and sets
* root/cwd of all processes which had them on the current root to new_root.
*
* Restrictions:
* The new_root and put_old must be directories, and must not be on the
* same file system as the current process root. The put_old must be
* underneath new_root, i.e. adding a non-zero number of /.. to the string
* pointed to by put_old must yield the same directory as new_root. No other
* file system may be mounted on put_old. After all, new_root is a mountpoint.
*
* Also, the current root cannot be on the 'rootfs' (initial ramfs) filesystem.
* See Documentation/filesystems/ramfs-rootfs-initramfs.txt for alternatives
* in this situation.
*
* Notes:
* - we don't move root/cwd if they are not at the root (reason: if something
* cared enough to change them, it's probably wrong to force them elsewhere)
* - it's okay to pick a root that isn't the root of a file system, e.g.
* /nfs/my_root where /nfs is the mount point. It must be a mountpoint,
* though, so you may need to say mount --bind /nfs/my_root /nfs/my_root
* first.

*
* When sampling multiple threads for RUSAGE_SELF, under SMP we might have
* races with threads incrementing their own counters. But since word
* reads are atomic, we either get new values or old values and we don't
* care which for the sums. We always take the siglock to protect reading
* the c* fields from p->signal from races with exit.c updating those
* fields when reaping, so a sample either gets all the additions of a
* given child after it's reaped, or none so this sample is before reaping.
*
* Locking:
* We need to take the siglock for CHILDEREN, SELF and BOTH
* for the cases current multithreaded, non-current single threaded
* non-current multithreaded. Thread traversal is now safe with
* the siglock held.
* Strictly speaking, we donot need to take the siglock if we are current and
* single threaded, as no one else can take our signal_struct away, no one
* else can reap the children to update signal->c* counters, and no one else
* can race with the signal-> fields. If we do not take any lock, the
* signal-> fields could be read out of order while another thread was just
* exiting. So we should place a read memory barrier when we avoid the lock.
* On the writer side, write memory barrier is implied in __exit_signal
* as __exit_signal releases the siglock spinlock after updating the signal->
* fields. But we don't do this yet to keep things simple.

* a lot simpler! (Which we're not doing right now because we're not
* measuring them yet).
*
* When sampling multiple threads for RUSAGE_SELF, under SMP we might have
* races with threads incrementing their own counters. But since word
* reads are atomic, we either get new values or old values and we don't
* care which for the sums. We always take the siglock to protect reading
* the c* fields from p->signal from races with exit.c updating those
* fields when reaping, so a sample either gets all the additions of a
* given child after it's reaped, or none so this sample is before reaping.
*
* Locking:
* We need to take the siglock for CHILDEREN, SELF and BOTH
* for the cases current multithreaded, non-current single threaded
* non-current multithreaded. Thread traversal is now safe with
* the siglock held.
* Strictly speaking, we donot need to take the siglock if we are current and
* single threaded, as no one else can take our signal_struct away, no one
* else can reap the children to update signal->c* counters, and no one else
* can race with the signal-> fields. If we do not take any lock, the
* signal-> fields could be read out of order while another thread was just
* exiting. So we should place a read memory barrier when we avoid the lock.
* On the writer side, write memory barrier is implied in __exit_signal
* as __exit_signal releases the siglock spinlock after updating the signal->
* fields. But we don't do this yet to keep things simple.

* port if it gets back a successful binding response.
* It also interops with JSTUN, a Java implementation of STUN.
* However, the JSTUN server refuses to respond to any binding request that
* doesn't have a CHANGE-REQUEST attribute in it.
* ... workaround is for the client to make a request with an empty CHANGE-REQUEST
* attribute (neither the ip or port bit are set)."

* port if it gets back a successful binding response.
* It also interops with JSTUN, a Java implementation of STUN.
* However, the JSTUN server refuses to respond to any binding request that
* doesn't have a CHANGE-REQUEST attribute in it.
* ... workaround is for the client to make a request with an empty CHANGE-REQUEST
* attribute (neither the ip or port bit are set)."

* is laid out as:
*
* bytes 0-3 chunk fourcc: 'VQHD'
* bytes 4-7 chunk size in big-endian format, should be 0x0000002A
* bytes 8-49 VQHD chunk data

* Bytes 8-49 are what this decoder expects to see.
*
* Briefly, VQA is a vector quantized animation format that operates in a
* VGA palettized colorspace. It operates on pixel vectors (blocks)
* of either 4x2 or 4x4 in size. Compressed VQA chunks can contain vector
* codebooks, palette information, and code maps for rendering vectors onto
* frames. Any of these components can also be compressed with a run-length
* encoding (RLE) algorithm commonly referred to as "format80".
*
* VQA takes a novel approach to rate control. Each group of n frames
* (usually, n = 8) relies on a different vector codebook. Rather than
* transporting an entire codebook every 8th frame, the new codebook is
* broken up into 8 pieces and sent along with the compressed video chunks
* for each of the 8 frames preceding the 8 frames which require the
* codebook. A full codebook is also sent on the very first frame of a
* file. This is an interesting technique, although it makes random file
* seeking difficult despite the fact that the frames are all intracoded.
*
* V1,2 VQA uses 12-bit codebook indexes. If the 12-bit indexes were
* packed into bytes and then RLE compressed, bytewise, the results would
* be poor. That is why the coding method divides each index into 2 parts,
* the top 4 bits and the bottom 8 bits, then RL encodes the 4-bit pieces
* together and the 8-bit pieces together. If most of the vectors are
* clustered into one group of 256 vectors, most of the 4-bit index pieces
* should be the same.

* nf_nat_snmp_basic.c
*
* Basic SNMP Application Layer Gateway
*
* This IP NAT module is intended for use with SNMP network
* discovery and monitoring applications where target networks use
* conflicting private address realms.
*
* Static NAT is used to remap the networks from the view of the network
* management system at the IP layer, and this module remaps some application
* layer addresses to match.
*
* The simplest form of ALG is performed, where only tagged IP addresses
* are modified. The module does not need to be MIB aware and only scans
* messages at the ASN.1/BER level.
*
* Currently, only SNMPv1 and SNMPv2 are supported.
*
* More information on ALG and associated issues can be found in
* RFC 2962
*
* The ASB.1/BER parsing code is derived from the gxsnmp package by Gregory
* McLean & Jochen Friedrich, stripped down for use in the kernel.

* nf_nat_snmp_basic.c
*
* Basic SNMP Application Layer Gateway
*
* This IP NAT module is intended for use with SNMP network
* discovery and monitoring applications where target networks use
* conflicting private address realms.
*
* Static NAT is used to remap the networks from the view of the network
* management system at the IP layer, and this module remaps some application
* layer addresses to match.
*
* The simplest form of ALG is performed, where only tagged IP addresses
* are modified. The module does not need to be MIB aware and only scans
* messages at the ASN.1/BER level.
*
* Currently, only SNMPv1 and SNMPv2 are supported.
*
* More information on ALG and associated issues can be found in
* RFC 2962
*
* The ASB.1/BER parsing code is derived from the gxsnmp package by Gregory
* McLean & Jochen Friedrich, stripped down for use in the kernel.

* VQA Video Decoder
* @author Mike Melanson (melanson@pcisys.net)
* @see http://wiki.multimedia.cx/index.php?title=VQA
*
* The VQA video decoder outputs PAL8 or RGB555 colorspace data, depending
* on the type of data in the file.
*
* This decoder needs the 42-byte VQHD header from the beginning
* of the VQA file passed through the extradata field. The VQHD header
* is laid out as:
*
* bytes 0-3 chunk fourcc: 'VQHD'
* bytes 4-7 chunk size in big-endian format, should be 0x0000002A
* bytes 8-49 VQHD chunk data
*
* Bytes 8-49 are what this decoder expects to see.
*
* Briefly, VQA is a vector quantized animation format that operates in a
* VGA palettized colorspace. It operates on pixel vectors (blocks)
* of either 4x2 or 4x4 in size. Compressed VQA chunks can contain vector
* codebooks, palette information, and code maps for rendering vectors onto
* frames. Any of these components can also be compressed with a run-length
* encoding (RLE) algorithm commonly referred to as "format80".
*
* VQA takes a novel approach to rate control. Each group of n frames
* (usually, n = 8) relies on a different vector codebook. Rather than
* transporting an entire codebook every 8th frame, the new codebook is
* broken up into 8 pieces and sent along with the compressed video chunks
* for each of the 8 frames preceding the 8 frames which require the
* codebook. A full codebook is also sent on the very first frame of a
* file. This is an interesting technique, although it makes random file
* seeking difficult despite the fact that the frames are all intracoded.
*
* V1,2 VQA uses 12-bit codebook indexes. If the 12-bit indexes were
* packed into bytes and then RLE compressed, bytewise, the results would
* be poor. That is why the coding method divides each index into 2 parts,
* the top 4 bits and the bottom 8 bits, then RL encodes the 4-bit pieces
* together and the 8-bit pieces together. If most of the vectors are
* clustered into one group of 256 vectors, most of the 4-bit index pieces
* should be the same.
