There are four functions, allowing compression and decompression in
the two formats we support so far. The functions will accept bytes or
unicode strings which are treated as utf-8.
The LZ77+Huffman decompression algorithm requires an exact target
length to decompress, so this is mandatory.
The plain decompression algorithm does not need an exact length, but
you can provide one to help it know how much space to allocate. As
currently written, you can provide a short length and it will often
succeed in decompressing to a different shorter string.
These bindings are intended to make ad-hoc investigation easier, not
for production use. This is reflected in the guesses about output size
that plain_decompress() makes if you don't supply one -- either they
are stupidly wasteful or ridiculously insufficient, depending on
whether or not you were trying to decompress a 20MB string.
>>> a = '12345678'
>>> import compression
>>> b = compression.huffman_compress(a)
>>> b
b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 #....
>>> len(b)
262
>>> c = compression.huffman_decompress(b, len(a))
>>> c
b'12345678' # note, c is bytes, a is str
>>> a
'12345678'
>>> d = compression.plain_compress(a)
>>> d
b'\xff\xff\xff\x0012345678'
>>> compression.plain_decompress(d) # no size specified, guesses
b'12345678'
>>> compression.plain_decompress(d,5)
b'12345'
>>> compression.plain_decompress(d,0) # 0 for auto
b'12345678'
>>> compression.plain_decompress(d,1)
b'1'
>>> compression.plain_decompress(a,444)
Traceback (most recent call last):
compression.CompressionError: unable to decompress data into a buffer of 444 bytes.
>>> compression.plain_decompress(b,444)
b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 #...
That last one decompresses the Huffman compressed file with the plain
compressor; pretty much any string is valid for plain decompression.

This uses the same hash table method as lzxpress_huffman, though the
code can't be directly reused as the sizes of the offsets is
different, and there is not a block processing step here.
This will worsen the compression ratio compared to the exhaustive
search we previously used, though we still perform better than
Windows. To put numbers on it, the test files used to compress to 0.91
of Windows' compression size, and now they compress to 0.96.
On the other hand this is many orders of magnitude faster. It is
difficult to say exactly how much faster -- while the testsuite time
has only improved 200-fold (from 7 minutes to 2 seconds), most of the
remaining 2 seconds is used in data generation and management, not
compression. OSSFuzz consistently finds new vectors that time out
after a minute; on these we'll see nearly an order of magnitude of
orders of magnitude inprovement.

This compresses files as described in MS-XCA 2.2, and as decompressed
by the decompressor in the previous commit.
As with the decompressor, there are two public functions -- one that
uses a talloc context, and one that uses pre-allocated memory. The
compressor requires a tightly bound amount of auxillary memory
(>220kB) in a few different buffers, which is all gathered together in
the public struct lzxhuff_compressor_mem. An instantiated but not
initialised copy of this struct is required by the non-talloc
function; it can be used over and over again.
Our compression speed is about the same as the decompression speed
(between 20 and 500 MB/s on this laptop, depending on the data), and
our compression ratio is very similar to that of Windows.

This format is described in [MS-XCA] 2.1 and 2.2, with exegesis in
many posts on the cifs-protocol list[1].
The two public functions are:
ssize_t lzxpress_huffman_decompress(const uint8_t *input,
size_t input_size,
uint8_t *output,
size_t output_size);
uint8_t *lzxpress_huffman_decompress_talloc(TALLOC_CTX *mem_ctx,
const uint8_t *input_bytes,
size_t input_size,
size_t output_size);
In both cases the caller needs to know the *exact* decompressed size,
which is essential for decompression. The _talloc version allocates
the buffer for you, and uses the talloc context to allocate a 128k
working buffer. THe non-talloc function will allocate the working
buffer on the stack.
This compression format gives better compression for messages of
several kilobytes than the "plain" LXZPRESS compression, but is
probably a bit slower to decompress and is certainly worse for very
short messages, having a fixed 256 byte overhead for the first Huffman
table.
Experiments show decompression rates between 20 and 500 MB per second,
depending on the compression ratio and data size, on an i5-1135G7 with
no compiler optimisations.
This compression format is used in AD claims and in SMB, but that
doesn't happen with this commit.
I will not try to describe LZ77 or Huffman encoding here. Don't expect
an answer in MS-XCA either; instead read the code and/or Wikipedia.

Sometimes (e.g. in lzxpress Huffman encoding, and in some of our
tests: c.f. https://lists.samba.org/archive/samba-technical/2018-March/126010.html)
we want a stable sort algorithm (meaning one that retains the previous
order of items that compare equal).
The GNU libc qsort() is *usually* stable, in that it first tries to
use a mergesort but reverts to quicksort if the necessary allocations
fail. That has led Samba developers to unthinkingly assume qsort() is
stable which is not the case on many platforms, and might not always
be on GNU/Linuxes either.
This adds four functions. stable_sort() sorts an array, and requires
an auxiliary working array of the same size. stable_sort_talloc()
takes a talloc context so it ca create a working array and call
stable_sort(). stable_sort_r() takes an opaque context blob that gets
passed to the compare function, like qsort_r() and ldb_qsort(). And
stable_sort_talloc_r() rounds out the quadrant.
These are LGPL so that the can be used in ldb, which has problems with
unstable sort.
The tests are borrowed and extended from test_ldb_qsort.c.
When sorting non-trivial structs this is roughly as fast as GNU qsort,
but GNU qsort has optimisations for small items, using direct
assignments of rather than memcpy where the size allows the item to be
cast as some kind of int.

There were some reports that strace output an LDAP server socket is in
CLOSE_WAIT state, returning EAGAIN for writev over and over (after a call to
epoll() each time).
In the tstream_bsd code the problem happens when we have a pending
writev_send, while there's no readv_send pending. In that case
we still ask for TEVENT_FD_READ in order to notice connection errors
early, so we try to call writev even if the socket doesn't report TEVENT_FD_WRITE.
And there are situations where we do that over and over again.
It happens like this with a Linux kernel:
tcp_fin() has this:
struct tcp_sock *tp = tcp_sk(sk);
inet_csk_schedule_ack(sk);
sk->sk_shutdown |= RCV_SHUTDOWN;
sock_set_flag(sk, SOCK_DONE);
switch (sk->sk_state) {
case TCP_SYN_RECV:
case TCP_ESTABLISHED:
/* Move to CLOSE_WAIT */
tcp_set_state(sk, TCP_CLOSE_WAIT);
inet_csk_enter_pingpong_mode(sk);
break;
It means RCV_SHUTDOWN gets set as well as TCP_CLOSE_WAIT, but
sk->sk_err is not changed to indicate an error.
tcp_sendmsg_locked has this:
...
err = -EPIPE;
if (sk->sk_err || (sk->sk_shutdown & SEND_SHUTDOWN))
goto do_error;
while (msg_data_left(msg)) {
int copy = 0;
skb = tcp_write_queue_tail(sk);
if (skb)
copy = size_goal - skb->len;
if (copy <= 0 || !tcp_skb_can_collapse_to(skb)) {
bool first_skb;
new_segment:
if (!sk_stream_memory_free(sk))
goto wait_for_space;
...
wait_for_space:
set_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
if (copied)
tcp_push(sk, flags & ~MSG_MORE, mss_now,
TCP_NAGLE_PUSH, size_goal);
err = sk_stream_wait_memory(sk, &timeo);
if (err != 0)
goto do_error;
It means if (sk->sk_err || (sk->sk_shutdown & SEND_SHUTDOWN)) doesn't
hit as we only have RCV_SHUTDOWN and sk_stream_wait_memory returns
-EAGAIN.
tcp_poll has this:
if (sk->sk_shutdown & RCV_SHUTDOWN)
mask |= EPOLLIN | EPOLLRDNORM | EPOLLRDHUP;
So we'll get EPOLLIN | EPOLLRDNORM | EPOLLRDHUP triggering
TEVENT_FD_READ and writev/sendmsg keeps getting EAGAIN.
So we need to always clear TEVENT_FD_READ if we don't
have readable handler in order to avoid burning cpu.
But we turn it on again after a timeout of 1 second
in order to monitor the error state of the connection.
And now that our tsocket_bsd_error() helper checks for POLLRDHUP,
we can check if the socket is in an error state before calling the
writable handler when TEVENT_FD_READ was reported.
Only on error we'll call the writable handler, which will pick
the error without calling writev().
