+Node types
+----------
+leaf
+ An end node with data. This has a copy of the relevant key, along
+ with 'hlist' with routing table entries sorted by prefix length.
+ See struct leaf and struct leaf_info.
+
+trie node or tnode
+ An internal node, holding an array of child (leaf or tnode) pointers,
+ indexed through a subset of the key. See Level Compression.
+
+A few concepts explained
+------------------------
+Bits (tnode)
+ The number of bits in the key segment used for indexing into the
+ child array - the "child index". See Level Compression.
+
+Pos (tnode)
+ The position (in the key) of the key segment used for indexing into
+ the child array. See Path Compression.
+
+Path Compression / skipped bits
+ Any given tnode is linked to from the child array of its parent, using
+ a segment of the key specified by the parent's "pos" and "bits"
+ In certain cases, this tnode's own "pos" will not be immediately
+ adjacent to the parent (pos+bits), but there will be some bits
+ in the key skipped over because they represent a single path with no
+ deviations. These "skipped bits" constitute Path Compression.
+ Note that the search algorithm will simply skip over these bits when
+ searching, making it necessary to save the keys in the leaves to
+ verify that they actually do match the key we are searching for.
+
+Level Compression / child arrays
+ the trie is kept level balanced moving, under certain conditions, the
+ children of a full child (see "full_children") up one level, so that
+ instead of a pure binary tree, each internal node ("tnode") may
+ contain an arbitrarily large array of links to several children.
+ Conversely, a tnode with a mostly empty child array (see empty_children)
+ may be "halved", having some of its children moved downwards one level,
+ in order to avoid ever-increasing child arrays.
+
+empty_children
+ the number of positions in the child array of a given tnode that are
+ NULL.
+
+full_children
+ the number of children of a given tnode that aren't path compressed.
+ (in other words, they aren't NULL or leaves and their "pos" is equal
+ to this tnode's "pos"+"bits").
+
+ (The word "full" here is used more in the sense of "complete" than
+ as the opposite of "empty", which might be a tad confusing.)
+
+Comments
+---------
+
+We have tried to keep the structure of the code as close to fib_hash as
+possible to allow verification and help up reviewing.
+
+fib_find_node()
+ A good start for understanding this code. This function implements a
+ straightforward trie lookup.
+
+fib_insert_node()
+ Inserts a new leaf node in the trie. This is bit more complicated than
+ fib_find_node(). Inserting a new node means we might have to run the
+ level compression algorithm on part of the trie.
+
+trie_leaf_remove()
+ Looks up a key, deletes it and runs the level compression algorithm.
+
+trie_rebalance()
+ The key function for the dynamic trie after any change in the trie
+ it is run to optimize and reorganize. Tt will walk the trie upwards
+ towards the root from a given tnode, doing a resize() at each step
+ to implement level compression.
+
+resize()
+ Analyzes a tnode and optimizes the child array size by either inflating
+ or shrinking it repeatedly until it fullfills the criteria for optimal
+ level compression. This part follows the original paper pretty closely
+ and there may be some room for experimentation here.
+
+inflate()
+ Doubles the size of the child array within a tnode. Used by resize().
+
+halve()
+ Halves the size of the child array within a tnode - the inverse of
+ inflate(). Used by resize();
+
+fn_trie_insert(), fn_trie_delete(), fn_trie_select_default()
+ The route manipulation functions. Should conform pretty closely to the
+ corresponding functions in fib_hash.
+
+fn_trie_flush()
+ This walks the full trie (using nextleaf()) and searches for empty
+ leaves which have to be removed.
+
+fn_trie_dump()
+ Dumps the routing table ordered by prefix length. This is somewhat
+ slower than the corresponding fib_hash function, as we have to walk the
+ entire trie for each prefix length. In comparison, fib_hash is organized
+ as one "zone"/hash per prefix length.
+
+Locking
+-------
+
+fib_lock is used for an RW-lock in the same way that this is done in fib_hash.
+However, the functions are somewhat separated for other possible locking
+scenarios. It might conceivably be possible to run trie_rebalance via RCU
+to avoid read_lock in the fn_trie_lookup() function.
+
+Main lookup mechanism
+---------------------
+fn_trie_lookup() is the main lookup function.
+
+The lookup is in its simplest form just like fib_find_node(). We descend the
+trie, key segment by key segment, until we find a leaf. check_leaf() does
+the fib_semantic_match in the leaf's sorted prefix hlist.
+
+If we find a match, we are done.
+
+If we don't find a match, we enter prefix matching mode. The prefix length,
+starting out at the same as the key length, is reduced one step at a time,
+and we backtrack upwards through the trie trying to find a longest matching
+prefix. The goal is always to reach a leaf and get a positive result from the
+fib_semantic_match mechanism.
+
+Inside each tnode, the search for longest matching prefix consists of searching
+through the child array, chopping off (zeroing) the least significant "1" of
+the child index until we find a match or the child index consists of nothing but
+zeros.
+
+At this point we backtrack (t->stats.backtrack++) up the trie, continuing to
+chop off part of the key in order to find the longest matching prefix.
+
+At this point we will repeatedly descend subtries to look for a match, and there
+are some optimizations available that can provide us with "shortcuts" to avoid
+descending into dead ends. Look for "HL_OPTIMIZE" sections in the code.
+
+To alleviate any doubts about the correctness of the route selection process,
+a new netlink operation has been added. Look for NETLINK_FIB_LOOKUP, which
+gives userland access to fib_lookup().

-<H3>Reading Images</H3>
-Each call to the <b>read</b> syscall returns the next available image
-from the device. It is up to the caller to set format and size (using
-the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
-size buffer and length to the function. Not all devices will support
-read operations.
-<P>
-A second way to handle image capture is via the mmap interface if supported.
-To use the mmap interface a user first sets the desired image size and depth
-properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
-of buffer to mmap and the offset within the buffer for each frame. The
-number of frames supported is device dependent and may only be one.
-<P>
-The video_mbuf structure contains the following fields
-<P>
-<TABLE>
-<TR><TD><b>size</b><TD>The number of bytes to map</TD>
-<TR><TD><b>frames</b><TD>The number of frames</TD>
-<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
-</TABLE>
-<P>
-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture. The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished. VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests. A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
- VIDIOCMCAPTURE(1)
- VIDIOCSYNC(0)
- /* process frame 0 while the hardware captures frame 1 */
- VIDIOCMCAPTURE(0)
- VIDIOCSYNC(1)
- /* process frame 1 while the hardware captures frame 0 */
-}
-</pre>
-Note that you are <em>not</em> limited to only two frames. The API
-allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
-frames the driver granted. Thus it is possible to build deeper queues
-to avoid loosing frames on load peaks.
-<p>
-While capturing to memory the driver will make a "best effort" attempt
-to capture to screen as well if requested. This normally means all
-frames that "miss" memory mapped capture will go to the display.
-<P>
-A final ioctl exists to allow a device to obtain related devices if a
-driver has multiple components (for example video0 may not be associated
-with vbi0 which would cause an intercast display program to make a bad
-mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
-devices if any exist. The video_unit structure has the following fields.
-<P>
-<TABLE>
-<TR><TD><b>video</b><TD>Video capture device</TD>
-<TR><TD><b>vbi</b><TD>VBI capture device</TD>
-<TR><TD><b>radio</b><TD>Radio device</TD>

-<TR><TD><b>teletext</b><TD>Teletext device</TD>
-</TABLE>
-<P>
-<H3>RDS Datastreams</H3>
-For radio devices that support it, it is possible to receive Radio Data
-System (RDS) data by means of a read() on the device. The data is packed in
-groups of three, as follows:
-<TABLE>
-<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR>
-<TR><TD>Second Octet</TD><TD>Most Significant Byte of RDS Block

- 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
- multiplies two u32 integers MULTIPLER and MULTIPLICAND,
- and generates a two-part u32 product in HIGH_PROD and
- LOW_PROD.
-
- 2) __umulsidi3(a,b) multiplies two u32 integers A and B,
- and returns a u64 product. This is just a variant of umul_ppmm.
-
- 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator) divides a two-word unsigned integer, composed by the
- integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
- places the quotient in QUOTIENT and the remainder in REMAINDER.
- HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
- If, in addition, the most significant bit of DENOMINATOR must be 1,
- then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
- 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator). Like udiv_qrnnd but the numbers are signed. The
- quotient is rounded towards 0.
-
- 5) count_leading_zeros(count, x) counts the number of zero-bits from
- the msb to the first non-zero bit. This is the number of steps X
- needs to be shifted left to set the msb. Undefined for X == 0.
-
- 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
- high_addend_2, low_addend_2) adds two two-word unsigned integers,
- composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
- LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
- LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
- lost.
-
- 7) sub_ddmmss(high_difference, low_difference, high_minuend,
- low_minuend, high_subtrahend, low_subtrahend) subtracts two
- two-word unsigned integers, composed by HIGH_MINUEND_1 and
- LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
- respectively. The result is placed in HIGH_DIFFERENCE and
- LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
- and is lost.
-
- If any of these macros are left undefined for a particular CPU,
- C macros are used. */

- * We get here for syscalls that don't have a lightweight handler. For those, we

- * pt_regs structure, and initializing the CPU state more or less as if an
- * interruption had occurred. To make syscall-restarts work, we setup pt_regs
- * such that cr_iip points to the second instruction in syscall_via_break.
- * Decrementing the IP hence will restart the syscall via break and not
- * decrementing IP will return us to the caller, as usual. Note that we preserve
- * the value of psr.pp rather than initializing it from dcr.pp. This makes it
- * possible to distinguish fsyscall execution from other privileged execution.

+ *
+ * We used to clear some PSR bits here but that requires slow

+ * The rationale is as follows: we used to clear bits
+ * ~PSR_PRESERVED_BITS in PSR.L. Since
+ * PSR_PRESERVED_BITS==PSR.{UP,MFL,MFH,PK,DT,PP,SP,RT,IC}, we
+ * ended up clearing PSR.{BE,AC,I,DFL,DFH,DI,DB,SI,TB}.
+ * However,
+ *
+ * PSR.BE : already is turned off in __kernel_syscall_via_epc()
+ * PSR.AC : don't care (kernel normally turns PSR.AC on)
+ * PSR.I : already turned off by the time fsys_bubble_down gets
+ * invoked
+ * PSR.DFL: always 0 (kernel never turns it on)
+ * PSR.DFH: don't care --- kernel never touches f32-f127 on its own
+ * initiative
+ * PSR.DI : always 0 (kernel never turns it on)
+ * PSR.SI : always 0 (kernel never turns it on)
+ * PSR.DB : don't care --- kernel never enables kernel-level
+ * breakpoints
+ * PSR.TB : must be 0 already; if it wasn't zero on entry to
+ * __kernel_syscall_via_epc, the branch to fsys_bubble_down
+ * will trigger a taken branch; the taken-trap-handler then
+ * converts the syscall into a break-based system-call.

- If you intend to attach a printer to the parallel port of your Linux
- box (as opposed to using a serial printer; if the connector at the
- printer has 9 or 25 holes ["female"], then it's serial), say Y.
- Also read the Printing-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- It is possible to share one parallel port among several devices
- (e.g. printer and ZIP drive) and it is safe to compile the
- corresponding drivers into the kernel. If you want to compile this
- driver as a module however, choose M here and read
- <file:Documentation/parport.txt>. The module will be called lp.
-
- If you have several parallel ports, you can specify which ports to
- use with the "lp" kernel command line option. (Try "man bootparam"
- or see the documentation of your boot loader (silo) about how to pass
- options to the kernel at boot time.) The syntax of the "lp" command
- line option can be found in <file:drivers/char/lp.c>.
-
- If you have more than 8 printers, you need to increase the LP_NO
- macro in lp.c and the PARPORT_MAX macro in parport.h.

- Performs one or both of the following actions:
-
- - Decompress more input starting at next_in and update next_in and avail_in
- accordingly. If not all input can be processed (because there is not
- enough room in the output buffer), next_in is updated and processing
- will resume at this point for the next call of inflate().
-
- - Provide more output starting at next_out and update next_out and avail_out
- accordingly. inflate() always provides as much output as possible
- (until there is no more input data or no more space in the output buffer).
-
- Before the call of inflate(), the application should ensure that at least
- one of the actions is possible, by providing more input and/or consuming
- more output, and updating the next_* and avail_* values accordingly.
- The application can consume the uncompressed output when it wants, for
- example when the output buffer is full (avail_out == 0), or after each
- call of inflate().
-
- If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,
- inflate flushes as much output as possible to the output buffer. The
- flushing behavior of inflate is not specified for values of the flush
- parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
- current implementation actually flushes as much output as possible
- anyway. For Z_PACKET_FLUSH, inflate checks that once all the input data
- has been consumed, it is expecting to see the length field of a stored
- block; if not, it returns Z_DATA_ERROR.
-
- inflate() should normally be called until it returns Z_STREAM_END or an
- error. However if all decompression is to be performed in a single step
- (a single call of inflate), the parameter flush should be set to
- Z_FINISH. In this case all pending input is processed and all pending
- output is flushed; avail_out must be large enough to hold all the
- uncompressed data. (The size of the uncompressed data may have been saved
- by the compressor for this purpose.) The next operation on this stream must
- be inflateEnd to deallocate the decompression state. The use of Z_FINISH
- is never required, but can be used to inform inflate that a faster routine
- may be used for the single inflate() call.
-
- inflate() returns Z_OK if some progress has been made (more input
- processed or more output produced), Z_STREAM_END if the end of the
- compressed data has been reached and all uncompressed output has been
- produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
- the stream structure was inconsistent (for example if next_in or next_out
- was NULL), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no
- progress is possible or if there was not enough room in the output buffer
- when Z_FINISH is used. In the Z_DATA_ERROR case, the application may then

- The windowBits parameter is the base two logarithm of the maximum window
- size (the size of the history buffer). It should be in the range 8..15 for
- this version of the library (the value 16 will be allowed soon). The
- default value is 15 if inflateInit is used instead. If a compressed stream
- with a larger window size is given as input, inflate() will return with
- the error code Z_DATA_ERROR instead of trying to allocate a larger window.
-
- If next_out is not null, the library will use this buffer for the history
- buffer; the buffer must either be large enough to hold the entire output
- data, or have at least 1<<windowBits bytes. If next_out is null, the
- library will allocate its own buffer (and leave next_out null). next_in
- need not be provided here but must be provided by the application for the

- Notes beyond the 1.93a appnote.txt:
-
- 1. Distance pointers never point before the beginning of the output
- stream.
- 2. Distance pointers can point back across blocks, up to 32k away.
- 3. There is an implied maximum of 7 bits for the bit length table and
- 15 bits for the actual data.
- 4. If only one code exists, then it is encoded using one bit. (Zero
- would be more efficient, but perhaps a little confusing.) If two
- codes exist, they are coded using one bit each (0 and 1).
- 5. There is no way of sending zero distance codes--a dummy must be
- sent if there are none. (History: a pre 2.0 version of PKZIP would
- store blocks with no distance codes, but this was discovered to be
- too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
- zero distance codes, which is sent as one code of zero bits in
- length.
- 6. There are up to 286 literal/length codes. Code 256 represents the
- end-of-block. Note however that the static length tree defines
- 288 codes just to fill out the Huffman codes. Codes 286 and 287
- cannot be used though, since there is no length base or extra bits
- defined for them. Similarily, there are up to 30 distance codes.
- However, static trees define 32 codes (all 5 bits) to fill out the
- Huffman codes, but the last two had better not show up in the data.
- 7. Unzip can check dynamic Huffman blocks for complete code sets.
- The exception is that a single code would not be complete (see #4).
- 8. The five bits following the block type is really the number of
- literal codes sent minus 257.
- 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
- (1+6+6). Therefore, to output three times the length, you output
- three codes (1+1+1), whereas to output four times the same length,
- you only need two codes (1+3). Hmm.
- 10. In the tree reconstruction algorithm, Code = Code + Increment
- only if BitLength(i) is not zero. (Pretty obvious.)
- 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
- 12. Note: length code 284 can represent 227-258, but length code 285
- really is 258. The last length deserves its own, short code
- since it gets used a lot in very redundant files. The length
- 258 is special since 258 - 3 (the min match length) is 255.
- 13. The literal/length and distance code bit lengths are read as a
- single stream of lengths. It is possible (and advantageous) for
- a repeat code (16, 17, or 18) to go across the boundary between
- the two sets of lengths.

- Huffman code decoding is performed using a multi-level table lookup.
- The fastest way to decode is to simply build a lookup table whose
- size is determined by the longest code. However, the time it takes
- to build this table can also be a factor if the data being decoded
- is not very long. The most common codes are necessarily the
- shortest codes, so those codes dominate the decoding time, and hence
- the speed. The idea is you can have a shorter table that decodes the
- shorter, more probable codes, and then point to subsidiary tables for
- the longer codes. The time it costs to decode the longer codes is
- then traded against the time it takes to make longer tables.
-
- This results of this trade are in the variables lbits and dbits
- below. lbits is the number of bits the first level table for literal/
- length codes can decode in one step, and dbits is the same thing for
- the distance codes. Subsequent tables are also less than or equal to
- those sizes. These values may be adjusted either when all of the
- codes are shorter than that, in which case the longest code length in
- bits is used, or when the shortest code is *longer* than the requested
- table size, in which case the length of the shortest code in bits is
- used.
-
- There are two different values for the two tables, since they code a
- different number of possibilities each. The literal/length table
- codes 286 possible values, or in a flat code, a little over eight
- bits. The distance table codes 30 possible values, or a little less
- than five bits, flat. The optimum values for speed end up being
- about one bit more than those, so lbits is 8+1 and dbits is 5+1.
- The optimum values may differ though from machine to machine, and
- possibly even between compilers. Your mileage may vary.

+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ algorithm.
+
+ Rijndael appears to be consistently a very good performer in
+ both hardware and software across a wide range of computing
+ environments regardless of its use in feedback or non-feedback
+ modes. Its key setup time is excellent, and its key agility is
+ good. Rijndael's very low memory requirements make it very well
+ suited for restricted-space environments, in which it also
+ demonstrates excellent performance. Rijndael's operations are
+ among the easiest to defend against power and timing attacks.
+
+ The AES specifies three key sizes: 128, 192 and 256 bits
