From e1d1c3189093ebe384953519083f815a420c4a4e Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Wed, 14 Sep 2016 20:50:35 +0200 Subject: [PATCH] opkg: vfork external gzip command to uncompress data Opkg's builtin decompression code is unsuitable to process nested archives as it uses a single shared state and relies on undefined seek behaviour for pipes. Rework the extraction logic to use the external gzip command as I/O filter for decompressing data and remove the builtin inflate code entirely. This shrinks the final opkg binary by about 4KB and results in less runtime memory consumption due to efficient use of vfork() and less copy-on-write operations in the forked child. Rework by Felix: create a thread that relays data to the gzip process instead of using a fragile poll loop Signed-off-by: Jo-Philipp Wich Signed-off-by: Felix Fietkau --- package/system/opkg/Makefile | 2 +- .../opkg/patches/070-use_external_gzip.patch | 719 ++++++++++++++++++ ...t.patch => 071-use_gzipped_pkg_list.patch} | 46 +- .../patches/220-drop-release-support.patch | 2 +- 4 files changed, 746 insertions(+), 23 deletions(-) create mode 100644 package/system/opkg/patches/070-use_external_gzip.patch rename package/system/opkg/patches/{070-use_gzipped_pkg_list.patch => 071-use_gzipped_pkg_list.patch} (85%) diff --git a/package/system/opkg/Makefile b/package/system/opkg/Makefile index 8b8904a39a..cbd731f54c 100644 --- a/package/system/opkg/Makefile +++ b/package/system/opkg/Makefile @@ -11,7 +11,7 @@ include $(INCLUDE_DIR)/version.mk include $(INCLUDE_DIR)/feeds.mk PKG_NAME:=opkg -PKG_RELEASE:=15 +PKG_RELEASE:=16 PKG_SOURCE_PROTO:=git PKG_SOURCE_URL:=http://git.yoctoproject.org/git/opkg diff --git a/package/system/opkg/patches/070-use_external_gzip.patch b/package/system/opkg/patches/070-use_external_gzip.patch new file mode 100644 index 0000000000..95873591de --- /dev/null +++ b/package/system/opkg/patches/070-use_external_gzip.patch @@ -0,0 +1,719 @@ +--- a/libbb/unarchive.c ++++ b/libbb/unarchive.c +@@ -28,6 +28,7 @@ + #include + + #include "libbb.h" ++#include "gzip.h" + + #define CONFIG_FEATURE_TAR_OLDGNU_COMPATABILITY 1 + #define CONFIG_FEATURE_TAR_GNU_EXTENSIONS +@@ -39,38 +40,15 @@ static char *linkname = NULL; + + off_t archive_offset; + +-#define SEEK_BUF 4096 + static ssize_t +-seek_by_read(FILE* fd, size_t len) +-{ +- ssize_t cc, total = 0; +- char buf[SEEK_BUF]; +- +- while (len) { +- cc = fread(buf, sizeof(buf[0]), +- len > SEEK_BUF ?
