zlib: Port fix for CVE-2018-25032 to U-Boot

2022-06-06T21:47:17Z

While our copy of zlib is missing upstream commit 263b1a05b04e ("Allow deflatePrime() to insert bits in the middle of a stream.") we do have Z_FIXED support, and so the majority of the code changes in 5c44459c3b28 ("Fix a bug that can crash deflate on some input when using Z_FIXED.") apply here directly and cleanly. As this has been assigned a CVE, lets go and apply these changes.

lib: zlib: our putc() takes only one argument

In contrast to the C99 standard [1] our putc() takes only one argument. [1] ISO/IEC 9899:1999 Signed-off-by: Heinrich Schuchardt

crc32: Use the crc.h header for crc functions

2019-12-02T23:23:08Z

Drop inclusion of crc.h in common.h and use the correct header directly instead. With this we can drop the conflicting definition in fw_env.h and rely on the crc.h header, which is already included. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

lib: zlib: remove the limitation for cannot using 0 as start

2012-09-29T14:26:08Z

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. Signed-off-by: Lei Wen
