2015-04-22gunzip: add gzwrite routine for extracting compresed images to block deviceEric Nelson
Initial filesystem images are generally highly compressible. Add a routine gzwrite that allows gzip-compressed images to be written to block devices. Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com> Reviewed-by: Tom Rini <trini@ti.com>
2015-01-14gunzip: Update lenp even on errorSimon Glass
This allows the caller to easily detect how much of the destination buffer has been used. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-09-03gzip: correctly bounds-check output bufferKees Cook
The output buffer size must not be reset by the gzip decoder or there is a risk of overflowing memory during decompression. Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

2012-04-30gunzip: rename z{alloc, free} to gz{alloc, free}Mike Frysinger
This allows us to add a proper zalloc() func (one that does a zeroing alloc), and removes duplicate prototypes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-12zlib/gunzip: Use WATCHDOG_RESET macroStefan Roese
As usually done in U-Boot, the watchdog_reset code is called via a macro (WATCHDOG_RESET). In zlib.c this was done differently, by using a function pointer which is initialized with WATCHDOG_RESET upon watchdog usage or with NULL otherwise. This patch now uses the plain WATCHDOG_RESET macros to call the function resulting in slightly smaller U-Boot images and simpler code. U-Boot code size reduction: PowerPC board with watchdog support (lwmon5): -> 80 bytes smaller image size PowerPC board without watchdog support (sequoia): -> 112 bytes smaller image size Signed-off-by: Stefan Roese <sr@denx.de> Cc: Detlev Zundel <dzu@denx.de> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
2010-04-13Rename lib_generic/ to lib/Peter Tyser
Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
