-+# When building a target filesystem, it is desirable to not have to
-+# become root and then run 'mknod' a thousand times. Using a device
-+# table you can create device nodes and directories "on the fly".
-+#
-+# This is a sample device table file for use with mkcramfs. You can
-+# do all sorts of interesting things with a device table file. For
-+# example, if you want to adjust the permissions on a particular file
-+# you can just add an entry like:
-+# /sbin/foobar f 2755 0 0 - - - - -
-+# and (assuming the file /sbin/foobar exists) it will be made setuid
-+# root (regardless of what its permissions are on the host filesystem.
-+# Furthermore, you can use a single table entry to create a many device
-+# minors. For example, if I wanted to create /dev/hda and /dev/hda[0-15]
-+# I could just use the following two table entries:
-+# /dev/hda b 640 0 0 3 0 0 0 -
-+# /dev/hda b 640 0 0 3 1 1 1 15
-+#
-+# Device table entries take the form of:
-+# <name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
-+# where name is the file name, type can be one of:
-+# f A regular file
-+# d Directory
-+# c Character special device file
-+# b Block special device file
-+# p Fifo (named pipe)
-+# uid is the user id for the target file, gid is the group id for the
-+# target file. The rest of the entries (major, minor, etc) apply only
-+# to device special files.

-# When building a target filesystem, it is desirable to not have to
-# become root and then run 'mknod' a thousand times. Using a device
-# table you can create device nodes and directories "on the fly".
-#
-# This is a sample device table file for use with genext2fs. You can
-# do all sorts of interesting things with a device table file. For
-# example, if you want to adjust the permissions on a particular file
-# you can just add an entry like:
-# /sbin/foobar f 2755 0 0 - - - - -
-# and (assuming the file /sbin/foobar exists) it will be made setuid
-# root (regardless of what its permissions are on the host filesystem.
-# Furthermore, you can use a single table entry to create a many device
-# minors. For example, if I wanted to create /dev/hda and /dev/hda[0-15]
-# I could just use the following two table entries:
-# /dev/hda b 640 0 0 3 0 0 0 -
-# /dev/hda b 640 0 0 3 1 1 1 15
-#
-# Device table entries take the form of:
-# <name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
-# where name is the file name, type can be one of:
-# f A regular file
-# d Directory
-# c Character special device file
-# b Block special device file
-# p Fifo (named pipe)
-# uid is the user id for the target file, gid is the group id for the
-# target file. The rest of the entries (major, minor, etc) apply only
-# to device special files.

-+/* This requires some explaining. If DNAT has taken place,
-+ * we will need to fix up the destination Ethernet address,
-+ * and this is a tricky process.
-+ *
-+ * There are two cases to consider:
-+ * 1. The packet was DNAT'ed to a device in the same bridge
-+ * port group as it was received on. We can still bridge
-+ * the packet.
-+ * 2. The packet was DNAT'ed to a different device, either
-+ * a non-bridged device or another bridge port group.
-+ * The packet will need to be routed.
-+ *
-+ * The correct way of distinguishing between these two cases is to
-+ * call ip_route_input() and to look at skb->dst->dev, which is
-+ * changed to the destination device if ip_route_input() succeeds.
-+ *
-+ * Let us first consider the case that ip_route_input() succeeds:
-+ *
-+ * If skb->dst->dev equals the logical bridge device the packet
-+ * came in on, we can consider this bridging. We then call
-+ * skb->dst->output() which will make the packet enter br_nf_local_out()
-+ * not much later. In that function it is assured that the iptables
-+ * FORWARD chain is traversed for the packet.
-+ *
-+ * Otherwise, the packet is considered to be routed and we just
-+ * change the destination MAC address so that the packet will
-+ * later be passed up to the IP stack to be routed.
-+ *
-+ * Let us now consider the case that ip_route_input() fails:
-+ *
-+ * After a "echo '0' > /proc/sys/net/ipv4/ip_forward" ip_route_input()
-+ * will fail, while __ip_route_output_key() will return success. The source
-+ * address for __ip_route_output_key() is set to zero, so __ip_route_output_key
-+ * thinks we're handling a locally generated packet and won't care
-+ * if IP forwarding is allowed. We send a warning message to the users's
-+ * log telling her to put IP forwarding on.
-+ *
-+ * ip_route_input() will also fail if there is no route available.
-+ * In that case we just drop the packet.

-- *
-- * Connection tracking protocol helper module for GRE.
-- *
-- * GRE is a generic encapsulation protocol, which is generally not very
-- * suited for NAT, as it has no protocol-specific part as port numbers.
-- *
-- * It has an optional key field, which may help us distinguishing two
-- * connections between the same two hosts.
-- *
-- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
-- *
-- * PPTP is built on top of a modified version of GRE, and has a mandatory
-- * field called "CallID", which serves us for the same purpose as the key
-- * field in plain GRE.
-- *
-- * Documentation about PPTP can be found in RFC 2637
-- *
-- * (C) 2000-2002 by Harald Welte <laforge@gnumonks.org>

-- * ip_nat_pptp.c - Version 1.11
-- *
-- * NAT support for PPTP (Point to Point Tunneling Protocol).
-- * PPTP is a a protocol for creating virtual private networks.
-- * It is a specification defined by Microsoft and some vendors
-- * working with Microsoft. PPTP is built on top of a modified
-- * version of the Internet Generic Routing Encapsulation Protocol.
-- * GRE is defined in RFC 1701 and RFC 1702. Documentation of
-- * PPTP can be found in RFC 2637
-- *
-- * (C) 2000-2002 by Harald Welte <laforge@gnumonks.org>
-- *
-- * Development of this code funded by Astaro AG (http://www.astaro.com/)
-- *
-- * TODO: - Support for multiple calls within one session
-- * (needs netfilter newnat code)
-- * - NAT to a unique tuple, not to TCP source port
-- * (needs netfilter tuple reservation)
-- * - Support other NAT scenarios than SNAT of PNS

-- * ip_nat_proto_gre.c - Version 1.11
-- *
-- * NAT protocol helper module for GRE.
-- *
-- * GRE is a generic encapsulation protocol, which is generally not very
-- * suited for NAT, as it has no protocol-specific part as port numbers.
-- *
-- * It has an optional key field, which may help us distinguishing two
-- * connections between the same two hosts.
-- *
-- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
-- *
-- * PPTP is built on top of a modified version of GRE, and has a mandatory
-- * field called "CallID", which serves us for the same purpose as the key
-- * field in plain GRE.
-- *
-- * Documentation about PPTP can be found in RFC 2637
-- *
-- * (C) 2000-2002 by Harald Welte <laforge@gnumonks.org>

-+ Swapping over network
-+
-+Support for this is enabled via the CONFIG_NETSWAP option, which is
-+automatically enabled when enabling swap files located on NFS volumes
-+(CONFIG_SWAP_VIA_NFS).
-+
-+When swapping to files located on a network file system like NFS or
-+CODA or others or to nbd (network block device, see `nbd.txt')
-+partitions there is the problem that this requires additional memory,
-+besides the page which is currently swapped in or out, probably at
-+least two more pages for each page in question.
-+
-+This means that not only there needs to be free space left in the swap
-+file or the swap partition, but in addition there must be enough free
-+memory left in the system to perform the swap out of pages.
-+
-+This is particularly painful as receiving data over the network itself
-+consumes memory, and this memory is allocated from an interrupt
-+context (i.e. in the interrupt handler of the network card). That
-+means that on a congested network there are chances that the machine
-+runs out of memory, simply because the network device's interrupt
-+routines allocate memory faster that it is freed by swapping via
-+network.
-+
-+To cope with this problem, there is a new socket option `SO_SWAPPING'
-+which has to be set on the `SOL_SOCKET' level with setsockopt() (see
-+setsockopt(2)). When this option is set on any network socket, then
-+the system will start to drop network packets it receives on any other
-+socket when the number of free pages falls below a certain threshold.
-+
-+This threshold initially is 4 pages less than `freepages.min' (see
-+`Documentation/sysctl/vm.txt') but can be tuned using the sysctl
-+interface by writing to the file `/proc/sys/net/swapping/threshold'
-+
-+There are two other files:
-+
-+`/proc/sys/net/swapping/dropped':
-+ how many network packets have been dropped so far. This file is
-+ writable, writing to it simply sets the counter to the given value
-+ (useful for resetting the counter).
-+
-+`/proc/sys/net/swapping/sock_count':
-+ How many network sockets have the `SO_SWAPPING' option set (read
-+ only, of course).
-+
-+When using swap-files on NFS volumes, then the `SO_SWAPPING' option is
-+set or cleared by swapon/swapoff system calls, so the user need not
-+care about it.
-+
-+Swapping over the network is insecure unless the data would be
-+encrypted, which is not the case with NFS. It is also very slow.

-+ Swapping to files on NFS volumes
-+
-+To do this you have to say `Y' or `M' to the CONFIG_SWAP_VIA_NFS
-+configuration option. When compling support for this as a module you
-+should read `Documentation/modules.txt'. For auto-loading of the
-+module during the `swapon' system call you have to place a line like
-+
-+alias swapfile-mod nfsswap
-+
-+in `/etc/modules.conf' (or `/etc/conf.modules', depending on your
-+setup). NFS volumes holding swapfile should be mounted with `rsize'
-+and `wsize' set to something less than the size of a page, otherwise
-+deadlocks caused by memory fragmentation can happen, i.e. mount the
-+volume which is to hold the swapfiles with
-+
-+mount -t nfs -o rsize=2048,wsize=2048 NFS_SERVER_IP:/server_volume /mount_point
-+
-+or set the option in `/etc/fstab'. Read `Documentation/nfsroot.txt' to
-+learn how to set mount options for the root file system, if your swap
-+files are to be located on the root file system.
-+
-+Setting the `rsize' and `wsize' to anything less than PAGE_SIZE is a
-+performance hit, so you probably want to have at least two volumes
-+mounted, one for the swapfiles, one for the rest.
-+
-+You may want to read `Documentation/netswap.txt' as well.
-+
-+Swapfiles on NFS volumes can be treated like any other swapfile,
-+i.e.
-+
-+dd if=/dev/zero of=/swapfiles/SWAPFILE bs=1k count=20480
-+mkswap /swapfiles/SWAPFILE
-+swapon /swapfiles/SWAPFILE
-+
-+will create a 20M swapfile and tell the system to use it. Actually,
-+one could use lseek(2) to create an empty swapfile. This is different
-+from swapfiles located on local harddisk.
-+
-+Swapping over the network is insecure unless the data would be
-+encrypted, which is not the case with NFS. It is also very slow.

+- * Connection tracking protocol helper module for GRE.
+- *
+- * GRE is a generic encapsulation protocol, which is generally not very
+- * suited for NAT, as it has no protocol-specific part as port numbers.
+- *
+- * It has an optional key field, which may help us distinguishing two
+- * connections between the same two hosts.
+- *
+- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+- *
+- * PPTP is built on top of a modified version of GRE, and has a mandatory
+- * field called "CallID", which serves us for the same purpose as the key
+- * field in plain GRE.
+- *
+- * Documentation about PPTP can be found in RFC 2637

+- * TODO: - Support for multiple calls within one session
+- * (needs netfilter newnat code)
+- * - NAT to a unique tuple, not to TCP source port
+- * (needs netfilter tuple reservation)
+- * - Support other NAT scenarios than SNAT of PNS

+- * ip_nat_proto_gre.c - Version 1.11
+- *
+- * NAT protocol helper module for GRE.
+- *
+- * GRE is a generic encapsulation protocol, which is generally not very
+- * suited for NAT, as it has no protocol-specific part as port numbers.
+- *
+- * It has an optional key field, which may help us distinguishing two
+- * connections between the same two hosts.
+- *
+- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+- *
+- * PPTP is built on top of a modified version of GRE, and has a mandatory
+- * field called "CallID", which serves us for the same purpose as the key
+- * field in plain GRE.
+- *
+- * Documentation about PPTP can be found in RFC 2637
+- *
+- * (C) 2000-2002 by Harald Welte <laforge@gnumonks.org>

++ Swapping over network
++
++Support for this is enabled via the CONFIG_NETSWAP option, which is
++automatically enabled when enabling swap files located on NFS volumes
++(CONFIG_SWAP_VIA_NFS).
++
++When swapping to files located on a network file system like NFS or
++CODA or others or to nbd (network block device, see `nbd.txt')
++partitions there is the problem that this requires additional memory,
++besides the page which is currently swapped in or out, probably at
++least two more pages for each page in question.
++
++This means that not only there needs to be free space left in the swap
++file or the swap partition, but in addition there must be enough free
++memory left in the system to perform the swap out of pages.
++
++This is particularly painful as receiving data over the network itself
++consumes memory, and this memory is allocated from an interrupt
++context (i.e. in the interrupt handler of the network card). That
++means that on a congested network there are chances that the machine
++runs out of memory, simply because the network device's interrupt
++routines allocate memory faster that it is freed by swapping via
++network.
++
++To cope with this problem, there is a new socket option `SO_SWAPPING'
++which has to be set on the `SOL_SOCKET' level with setsockopt() (see
++setsockopt(2)). When this option is set on any network socket, then
++the system will start to drop network packets it receives on any other
++socket when the number of free pages falls below a certain threshold.
++
++This threshold initially is 4 pages less than `freepages.min' (see
++`Documentation/sysctl/vm.txt') but can be tuned using the sysctl
++interface by writing to the file `/proc/sys/net/swapping/threshold'
++
++There are two other files:
++
++`/proc/sys/net/swapping/dropped':
++ how many network packets have been dropped so far. This file is
++ writable, writing to it simply sets the counter to the given value
++ (useful for resetting the counter).
++
++`/proc/sys/net/swapping/sock_count':
++ How many network sockets have the `SO_SWAPPING' option set (read
++ only, of course).
++
++When using swap-files on NFS volumes, then the `SO_SWAPPING' option is
++set or cleared by swapon/swapoff system calls, so the user need not
++care about it.
++
++Swapping over the network is insecure unless the data would be
++encrypted, which is not the case with NFS. It is also very slow.

++ Swapping to files on NFS volumes
++
++To do this you have to say `Y' or `M' to the CONFIG_SWAP_VIA_NFS
++configuration option. When compling support for this as a module you
++should read `Documentation/modules.txt'. For auto-loading of the
++module during the `swapon' system call you have to place a line like
++
++alias swapfile-mod nfsswap
++
++in `/etc/modules.conf' (or `/etc/conf.modules', depending on your
++setup). NFS volumes holding swapfile should be mounted with `rsize'
++and `wsize' set to something less than the size of a page, otherwise
++deadlocks caused by memory fragmentation can happen, i.e. mount the
++volume which is to hold the swapfiles with
++
++mount -t nfs -o rsize=2048,wsize=2048 NFS_SERVER_IP:/server_volume /mount_point
++
++or set the option in `/etc/fstab'. Read `Documentation/nfsroot.txt' to
++learn how to set mount options for the root file system, if your swap
++files are to be located on the root file system.
++
++Setting the `rsize' and `wsize' to anything less than PAGE_SIZE is a
++performance hit, so you probably want to have at least two volumes
++mounted, one for the swapfiles, one for the rest.
++
++You may want to read `Documentation/netswap.txt' as well.
++
++Swapfiles on NFS volumes can be treated like any other swapfile,
++i.e.
++
++dd if=/dev/zero of=/swapfiles/SWAPFILE bs=1k count=20480
++mkswap /swapfiles/SWAPFILE
++swapon /swapfiles/SWAPFILE
++
++will create a 20M swapfile and tell the system to use it. Actually,
++one could use lseek(2) to create an empty swapfile. This is different
++from swapfiles located on local harddisk.
++
++Swapping over the network is insecure unless the data would be
++encrypted, which is not the case with NFS. It is also very slow.

++/* This requires some explaining. If DNAT has taken place,
++ * we will need to fix up the destination Ethernet address,
++ * and this is a tricky process.
++ *
++ * There are two cases to consider:
++ * 1. The packet was DNAT'ed to a device in the same bridge
++ * port group as it was received on. We can still bridge
++ * the packet.
++ * 2. The packet was DNAT'ed to a different device, either
++ * a non-bridged device or another bridge port group.
++ * The packet will need to be routed.
++ *
++ * The correct way of distinguishing between these two cases is to
++ * call ip_route_input() and to look at skb->dst->dev, which is
++ * changed to the destination device if ip_route_input() succeeds.
++ *
++ * Let us first consider the case that ip_route_input() succeeds:
++ *
++ * If skb->dst->dev equals the logical bridge device the packet
++ * came in on, we can consider this bridging. We then call
++ * skb->dst->output() which will make the packet enter br_nf_local_out()
++ * not much later. In that function it is assured that the iptables
++ * FORWARD chain is traversed for the packet.
++ *
++ * Otherwise, the packet is considered to be routed and we just
++ * change the destination MAC address so that the packet will
++ * later be passed up to the IP stack to be routed.
++ *
++ * Let us now consider the case that ip_route_input() fails:
++ *
++ * After a "echo '0' > /proc/sys/net/ipv4/ip_forward" ip_route_input()
++ * will fail, while __ip_route_output_key() will return success. The source
++ * address for __ip_route_output_key() is set to zero, so __ip_route_output_key
++ * thinks we're handling a locally generated packet and won't care
++ * if IP forwarding is allowed. We send a warning message to the users's
++ * log telling her to put IP forwarding on.
++ *
++ * ip_route_input() will also fail if there is no route available.
++ * In that case we just drop the packet.

+
+/* First, the polynomial itself and its table of feedback terms. The */
+/* polynomial is */
+/* X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0 */
+/* Note that we take it "backwards" and put the highest-order term in */
+/* the lowest-order bit. The X^32 term is "implied"; the LSB is the */
+/* X^31 term, etc. The X^0 term (usually shown as "+1") results in */
+/* the MSB being 1. */
+
+/* Note that the usual hardware shift register implementation, which */
+/* is what we're using (we're merely optimizing it by doing eight-bit */
+/* chunks at a time) shifts bits into the lowest-order term. In our */
+/* implementation, that means shifting towards the right. Why do we */
+/* do it this way? Because the calculated CRC must be transmitted in */
+/* order from highest-order term to lowest-order term. UARTs transmit */
+/* characters in order from LSB to MSB. By storing the CRC this way, */
+/* we hand it to the UART in the order low-byte to high-byte; the UART */
+/* sends each low-bit to hight-bit; and the result is transmission bit */
+/* by bit from highest- to lowest-order term without requiring any bit */
+/* shuffling on our part. Reception works similarly. */
+
+/* The feedback terms table consists of 256, 32-bit entries. Notes: */
+/* */
+/* 1. The table can be generated at runtime if desired; code to do so */
+/* is shown later. It might not be obvious, but the feedback */
+/* terms simply represent the results of eight shift/xor opera- */
+/* tions for all combinations of data and CRC register values. */
+/* */
+/* 2. The CRC accumulation logic is the same for all CRC polynomials, */
+/* be they sixteen or thirty-two bits wide. You simply choose the */
+/* appropriate table. Alternatively, because the table can be */
+/* generated at runtime, you can start by generating the table for */
+/* the polynomial in question and use exactly the same "updcrc", */
+/* if your application needn't simultaneously handle two CRC */
+/* polynomials. (Note, however, that XMODEM is strange.) */
+/* */
+/* 3. For 16-bit CRCs, the table entries need be only 16 bits wide; */
+/* of course, 32-bit entries work OK if the high 16 bits are zero. */
+/* */
+/* 4. The values must be right-shifted by eight bits by the "updcrc" */
+/* logic; the shift must be unsigned (bring in zeroes). On some */
+/* hardware you could probably optimize the shift in assembler by */
+/* using byte-swap instructions. */
