From cd96421b19a4c9dd058cee724cc5b4fe5f0d74db Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 13 Feb 2015 07:42:13 +0000 Subject: [PATCH] kexec-tools: bump version from v2.0.4 to v2.0.9. - kexec-tools is now distributed with tarballs of .tar.gz and .tar.xz format; .tar.bz2 are not provided anymore. - Add CONFIG_KEXEC_LZMA for selecting lzma support. Patches are updated along to: - Remove the now unnecessary patch 0004-mips_regdefs.patch. - Drop 100-reduce_size.patch because the size reduction is marginal. - Allow zlib and lzma support coexist together. This patch has been merged into upstream project. - Fix kexec-tools' configure.ac. - Fix a few compilation warnings. Size comparison of stripped binaries of kexec malta target with both zlib and lzma support enabled. - Before: 41447 - After: 42583 Signed-off-by: Yousong Zhou SVN-Revision: 44437 --- package/boot/kexec-tools/Config.in | 5 + package/boot/kexec-tools/Makefile | 12 +- .../0001-Fix-zlib-lzma-decompression.patch | 171 ++++++++++++++++++ ...ly-necessary-quotes-to-result-of-mac.patch | 52 ++++++ ...r-warning-on-printing-64-bit-integer.patch | 35 ++++ .../0004-mips-remove-unused-variable.patch | 30 +++ .../patches/0004-mips_regdefs.patch | 103 ----------- ...rning-about-implicit-type-conversion.patch | 30 +++ .../kexec-tools/patches/100-reduce_size.patch | 36 ---- 9 files changed, 329 insertions(+), 145 deletions(-) create mode 100644 package/boot/kexec-tools/patches/0001-Fix-zlib-lzma-decompression.patch create mode 100644 package/boot/kexec-tools/patches/0002-configure.ac-apply-necessary-quotes-to-result-of-mac.patch create mode 100644 package/boot/kexec-tools/patches/0003-mips-fix-compiler-warning-on-printing-64-bit-integer.patch create mode 100644 package/boot/kexec-tools/patches/0004-mips-remove-unused-variable.patch delete mode 100644 package/boot/kexec-tools/patches/0004-mips_regdefs.patch create mode 100644 package/boot/kexec-tools/patches/0005-mips-fix-warning-about-implicit-type-conversion.patch delete mode 100644 package/boot/kexec-tools/patches/100-reduce_size.patch diff --git a/package/boot/kexec-tools/Config.in b/package/boot/kexec-tools/Config.in index 2642171bb0..6c7558f30a 100644 --- a/package/boot/kexec-tools/Config.in +++ b/package/boot/kexec-tools/Config.in @@ -23,4 +23,9 @@ config KEXEC_ZLIB prompt "zlib support" default y +config KEXEC_LZMA + bool + prompt "lzma support" + default n + endmenu diff --git a/package/boot/kexec-tools/Makefile b/package/boot/kexec-tools/Makefile index e884661c38..e5d4b4b2f4 100644 --- a/package/boot/kexec-tools/Makefile +++ b/package/boot/kexec-tools/Makefile @@ -8,23 +8,23 @@ include $(TOPDIR)/rules.mk PKG_NAME:=kexec-tools -PKG_VERSION:=2.0.4 +PKG_VERSION:=2.0.9 PKG_RELEASE:=1 -PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.bz2 +PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.xz PKG_SOURCE_URL:=@KERNEL/linux/utils/kernel/kexec -PKG_MD5SUM:=05992bc8c0673fc55be7b6d27e48a8db +PKG_MD5SUM:=6681319934e22e74c532bd392ccb1bbb PKG_FIXUP:=autoreconf -PKG_CONFIG_DEPENDS := CONFIG_KEXEC_ZLIB +PKG_CONFIG_DEPENDS := CONFIG_KEXEC_ZLIB CONFIG_KEXEC_LZMA include $(INCLUDE_DIR)/package.mk define Package/kexec-tools SECTION:=utils CATEGORY:=Utilities - DEPENDS:=@KERNEL_KEXEC @armeb||@arm||@i386||@powerpc64||@mipsel||@mips +KEXEC_ZLIB:zlib + DEPENDS:=@KERNEL_KEXEC @armeb||@arm||@i386||@powerpc64||@mipsel||@mips +KEXEC_ZLIB:zlib +KEXEC_LZMA:liblzma TITLE:=Kernel boots kernel URL:=http://kernel.org/pub/linux/kernel/people/horms/kexec-tools/ MAINTAINER:=Florian Fainelli @@ -55,7 +55,7 @@ CONFIGURE_ARGS = \ --libexecdir=/usr/lib \ --sysconfdir=/etc \ $(if $(CONFIG_KEXEC_ZLIB),--with,--without)-zlib \ - --without-lzma + $(if $(CONFIG_KEXEC_LZMA),--with,--without)-lzma TARGET_CFLAGS += -ffunction-sections -fdata-sections TARGET_LDFLAGS += -Wl,--gc-sections diff --git a/package/boot/kexec-tools/patches/0001-Fix-zlib-lzma-decompression.patch b/package/boot/kexec-tools/patches/0001-Fix-zlib-lzma-decompression.patch new file mode 100644 index 0000000000..06c11ec350 --- /dev/null +++ b/package/boot/kexec-tools/patches/0001-Fix-zlib-lzma-decompression.patch @@ -0,0 +1,171 @@ +From d606837b56d46eb7f815b5d85f07fcc3f1555d00 Mon Sep 17 00:00:00 2001 +From: Yousong Zhou +Date: Sun, 1 Feb 2015 00:10:07 +0800 +Subject: [PATCH 1/5] Fix zlib/lzma decompression. + +Let {zlib,lzma}_decompress_file() return NULL if anything wrong happened +to allow the other method to have a chance to run. + +Signed-off-by: Yousong Zhou +Signed-off-by: Simon Horman +--- + kexec/lzma.c | 33 ++++++++++++++++++++++----------- + kexec/zlib.c | 57 +++++++++++++++++++++++++++++++++++---------------------- + 2 files changed, 57 insertions(+), 33 deletions(-) + +diff --git a/kexec/lzma.c b/kexec/lzma.c +index 939aeb3..5bfccb7 100644 +--- a/kexec/lzma.c ++++ b/kexec/lzma.c +@@ -162,13 +162,16 @@ char *lzma_decompress_file(const char *filename, off_t *r_size) + off_t size, allocated;
