2020-08-07include/u-boot, lib/zlib: add sources for zlib decompressionJoao Marcos Costa
Add zlib (v1.2.11) uncompr() function to U-Boot. SquashFS depends on this function to decompress data from a raw disk image. The actual support for zlib into SquashFS sources will be added in a follow-up commit. Signed-off-by: Joao Marcos Costa <joaomarcos.costa@bootlin.com>
2020-07-17lib: zlib: Remove offset pointer optimization in inftrees.cChin Liang See
This fixes the CVE-2016-9840. Commit imported from [1]. inftrees.c was subtracting an offset from a pointer to an array, in order to provide a pointer that allowed indexing starting at the offset. This is not compliant with the C standard, for which the behavior of a pointer decremented before its allocated memory is undefined. Per the recommendation of a security audit of the zlib code by Trail of Bits and TrustInSoft, in support of the Mozilla Foundation, this tiny optimization was removed, in order to avoid the possibility of undefined behavior.

2020-01-17common: Move hang() to the same header as panic()Simon Glass
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2015-09-11Move malloc_cache_aligned() to its own headerSimon Glass
At present malloc.h is included everywhere since it recently was added to common.h in this commit: 4519668 mtd/nand/ubi: assortment of alignment fixes This seems wasteful and unnecessary. We have been trying to trim down common.h and put separate functions into separate header files and that change goes in the opposite direction. Move malloc_cache_aligned() to a new header so that this can be avoided. The header would perhaps be better named as alignmem.h but it needs to be included after common.h and people might be confused by this. With the name memalign.h it fits nicely after malloc() in most cases. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

2012-09-29lib: zlib: remove the limitation for cannot using 0 as startLei Wen
We often need the requirement that compressing those memory range start from 0, but the default deflate code in zlib prevent us to do this. Considering the special case of uboot, that it could access all memory range, it is reasonable to be able to also take the address space from 0 into compression.

2011-10-17zlib: handle overflow while calculating available stream input sizeAnatolij Gustschin
If compressed data is located in sectors at the end of the flash and it's offset + input stream size > 0xFFFFFFFF, the uncompressing time is very long, since processing of the stream is done bytewise (and not blockwise) due to overflow in inflate_fast() while calculation and checking for enough input available. Check for this overflow condition and limit the available stream input size to the actually max. possible input size. This fixes the problem. The issue is easily reproduceable by placing a gziped bitmap in flash, e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000' or 'bmp display FFF80000'. The uncompressing can take up to 3 sec. whereas it should normaly take a fraction of a second. If the 'splashimage' environment variable points to this address, the booting time also increases significantly. Signed-off-by: Anatolij Gustschin <agust@denx.de>

2011-04-30zlib: split up to match original source treeMike Frysinger
While looking to upgrade to zlib-1.2.5, the current mondo merge of multiple files into a single was making things way more difficult than it should have been. Hard to pick out what has been changed to port it to U-Boot, been removed as useless, and bug fixes added after the fact. So split the single file up into the original file names, and merge non-essential changes back from the original tree (for some reason, style in code in a bunch of places was changed to U-Boot style even though this isn't "U-Boot" code). The original build style is retained -- we have a single zlib.c that includes all the other files, and that is the only file we compile. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
