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>
2015-01-14lzma: fix buffer bound check error furtherSimon Glass
Commit 4d3b8a0d fixed a problem with lzma decompress where it would run out of bytes to decompress. The algorithm needs to know how many uncompressed bytes it is expected to produce. However, the fix introduced a potential buffer overrun, and causes the compression test to fail (test_compression command in sandbox). The correct fix seems to be to use the minimum of the expected number of uncompressed bytes and the amount of output space available. That way things work normally when there is enough space, and return an error (without overrunning available space) when there is not.

2014-06-11LzmaTools: don't self assign valuesJeroen Hofstee
It seems the code tries to trick the compiler the argument is actually used. However compilers became too smart to fool them so easily an now warn. Gcc and clang don't seem to emit a warning when the argument is unused. If so it should be decorated with unused / (void). Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

2014-01-14lzma: fix buffer bound check errorAntonios Vamporakis
Variable uncompressedSize references the space available, while outSizeFull is the actual expected uncompressed size. Using the wrong value causes LzmaDecode to return SZ_ERROR_INPUT_EOF. Problem was introduced in commit afca294. While at it add additional debug message.

2013-09-03lzma: correctly bounds-check output bufferKees Cook
The output buffer size must be correctly passed to the lzma decoder or there is a risk of overflowing memory during decompression. Switching to the LZMA_FINISH_END mode means nothing is left in an unknown state once the buffer becomes full. Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

Updated code taken from latest lzma sdk release 9.20 at http://downloads.sourceforge.net/sevenzip/lzma920.tar.bz2 This generates quite a lot of checkpatch warnings, but I guess we need to keep the code style as is to avoid a massive job each time we update this.

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
