Subject: [PATCH 1/3] Neon-Optimized hash chain rebase
This should help with compression of data, using NEON instructions
(therefore useful for ARMv7/ARMv8).

Subject: [PATCH 2/3] Porting optimized longest_match
This patch was contributed to zlib-ng and features an improved longest_match
function using the most distant hash code to reduce number of checks
(see: http://www.gildor.org/en/projects/zlib).
Original patch by Jun He.

From 41ebac8b7d7485a5396ae25ce2412cafcd03f1a2 Mon Sep 17 00:00:00 2001
From: liqiang <liqiang64@huawei.com>
Date: Thu, 2 Sep 2021 17:31:48 +0800
Subject: [PATCH] Accelerate Adler32 using arm64 SVE instructions
This patch uses the SVE instruction set to rewrite the Adler32
algorithm (checksum algorithm in libz). By dividing the data into
blocks, a vector operation can complete a data block in parallel.
Measured on a Taishan 1951 machine that supports 256bit width SVE,
this algorithm is about 3~5 times faster than the algorithm implemented
in C language in libz. The wider the bit width, the better the
acceleration effect. Below are the results of my measured random
data of 1M and 10M:
[root@xxx adler32]# ./benchmark 1000000
Libz alg: Time used: 608 us, 1644.7 Mb/s.
SVE alg: Time used: 166 us, 6024.1 Mb/s.
[root@xxx adler32]# ./benchmark 10000000
Libz alg: Time used: 6484 us, 1542.3 Mb/s.
SVE alg: Time used: 2034 us, 4916.4 Mb/s.
On machines that support ARM64 sve instructions, this algorithm can
effectively accelerate adler32, thereby achieving the effect of improving
the performance of the basic compression algorithm libz.
In the implementation of this patch, blocks can be of any size, so the
algorithm can automatically adapt to SVE hardware with different bit
widths without modifying the code.

Subject: [PATCH] Fix a bug that can crash deflate on some input when using
Z_FIXED.
This bug was reported by Danilo Ramos of Eideticom, Inc. It has
lain in wait 13 years before being found! The bug was introduced
in zlib 1.2.2.2, with the addition of the Z_FIXED option. That
option forces the use of fixed Huffman codes. For rare inputs with
a large number of distant matches, the pending buffer into which
the compressed data is written can overwrite the distance symbol
table which it overlays. That results in corrupted output due to
invalid distances, and can result in out-of-bound accesses,
crashing the application.
The fix here combines the distance buffer and literal/length
buffers into a single symbol buffer. Now three bytes of pending
buffer space are opened up for each literal or length/distance
pair consumed, instead of the previous two bytes. This assures
that the pending buffer cannot overwrite the symbol table, since
the maximum fixed code compressed length/distance is 31 bits, and
since there are four bytes of pending space for every three bytes
of symbol space.

+ * Analysis: The longest fixed codes are a length code of 8 bits plus 5
+ * extra bits, for lengths 131 to 257. The longest fixed distance codes are
+ * 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest
+ * possible fixed-codes length/distance pair is then 31 bits total.
+ *
+ * sym_buf starts one-fourth of the way into pending_buf. So there are
+ * three bytes in sym_buf for every four bytes in pending_buf. Each symbol
+ * in sym_buf is three bytes -- two for the distance and one for the
+ * literal/length. As each symbol is consumed, the pointer to the next
+ * sym_buf value to read moves forward three bytes. From that symbol, up to
+ * 31 bits are written to pending_buf. The closest the written pending_buf
+ * bits gets to the next sym_buf symbol to read is just before the last
+ * code is written. At that time, 31*(n-2) bits have been written, just
+ * after 24*(n-2) bits have been consumed from sym_buf. sym_buf starts at
+ * 8*n bits into pending_buf. (Note that the symbol buffer fills when n-1
+ * symbols are written.) The closest the writing gets to what is unread is
+ * then n+14 bits. Here n is lit_bufsize, which is 16384 by default, and
+ * can range from 128 to 32768.
+ *
+ * Therefore, at a minimum, there are 142 bits of space between what is
+ * written and what is read in the overlain buffers, so the symbols cannot
+ * be overwritten by the compressed data. That space is actually 139 bits,
+ * due to the three-bit fixed-code block header.
+ *
+ * That covers the case where either Z_FIXED is specified, forcing fixed
+ * codes, or when the use of fixed codes is chosen, because that choice
+ * results in a smaller compressed block than dynamic codes. That latter
+ * condition then assures that the above analysis also covers all dynamic
+ * blocks. A dynamic-code block will only be chosen to be emitted if it has
+ * fewer bits than a fixed-code block would for the same set of symbols.
+ * Therefore its average symbol length is assured to be less than 31. So
+ * the compressed data for a dynamic block also cannot overwrite the
+ * symbols from which it is being constructed.

Subject: [PATCH] Fix a bug when getting a gzip header extra field with
inflate().
If the extra field was larger than the space the user provided with
inflateGetHeader(), and if multiple calls of inflate() delivered
the extra header data, then there could be a buffer overflow of the
provided space. This commit assures that provided space is not
exceeded.

Subject: [PATCH] zlib-1.2.11-SIMD.patch
In the sampling of the Hive test program, it is found that inflate occupies a high proportion.
The zlib is optimized through instruction set optimization, hash replacement, and compilation option optimization.
The inflate and deflate processes of the Zlib library provided by the JDK are optimized to shorten the invoking time.
