[PATCH] libelf: decompress: ensure zlib resource cleanup

__libelf_decompress would only cleanup zlib resources via inflateEnd() in case inflating was successful, but would leak memory if not. Fix this by calling inflateEnd() in the error case as well. Fixes: 272018bba1f2 ("libelf: Add elf_compress and elf_compress_gnu.") Signed-off-by: Matthias Maennich

[PATCH] dwfl: fix potential overflow when reporting on kernel modules

dwfl_linux_kernel_report_modules_ has an outstanding ancient bug when reading kernel module information from a modules list file. The target buffer for the module name was sized too small to hold potential values. Fix that by increasing the value to account for the null termination. In practice, t
