[ZLIB]: Fix external builds of zlib_inflate code.

2007-10-12T05:17:20Z

Move zlib_inflate_blob() out into it's own source file, infutil.c, so that things like the powerpc zImage builder in arch/powerpc/boot/Makefile don't end up trying to compile it. Signed-off-by: David S. Miller

Fix ppp_deflate issues with recent zlib_inflate changes

2007-05-07T19:13:04Z

The last zlib_inflate update broke certain corner cases for ppp_deflate decompression handling. This patch fixes some logic to make things work properly again. Users other than ppp_deflate (the only Z_PACKET_FLUSH user) should be unaffected.

[PATCH] Fix ppc32 zImage inflate

2006-07-31T20:28:37Z

The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302) broke ppc32 zImage decompression as it tries to decompress to address zero and the updated zlib_inflate checks that strm->next_out isn't a null pointer. This little patch fixes it.

Fix function definitions to be ANSI-compliant: lib/zlib_inflate/inffast.c:68:1: warning: non-ANSI definition of function 'inflate_fast' lib/zlib_inflate/inftrees.c:33:1: warning: non-ANSI definition of function 'zlib_inflate_table' Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

move acknowledgment for Mark Adler to CREDITS

The place in the documentation of the Linux kernel to acknowledge contributions is the CREDITS file. Give Mark Adler an entry there instead of including a string in the kernel image. Signed-off-by: Adrian Bunk

[PATCH] zlib_inflate: Upgrade library code to a recent version

2006-06-22T22:05:58Z

Upgrade the zlib_inflate implementation in the kernel from a patched version 1.1.3/4 to a patched 1.2.3. The code in the kernel is about seven years old and I noticed that the external zlib library's inflate performance was significantly faster (~50%) than the code in the kernel on ARM (and faster again on x86_32). For comparison the newer deflate code is 20% slower on ARM and 50% slower on x86_32 but gives an approx 1% compression ratio improvement. I don't consider this to be an improvement for kernel use so have no plans to change the zlib_deflate code. Various changes have been made to the zlib code in the kernel, the most significant being the extra functions/flush option used by ppp_deflate. This update reimplements the features PPP needs to ensure it continues to work. This code has been tested on ARM under both JFFS2 (with zlib compression enabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% real world file read speed improvement. This patch also removes ZLIB_VERSION as it no longer has a correct value. We don't need version checks anyway as the kernel's module handling will take care of that for us. This removal is also more in keeping with the zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've added something to the zlib.h header to note its a modified version.

Revert unnecessary zlib_inflate/inftrees.c fix

2005-08-17T20:07:28Z

It turns out that empty distance code tables are not an error, and that a compressed block with only literals can validly have an empty table and should not be flagged as a data error. Some old versions of gzip had problems with this case, but it does not affect the zlib code in the kernel. Analysis and explanations thanks to Sergey Vlasov Signed-off-by: Linus Torvalds
