openwrt补丁

http://wiki.openwrt.org/doc/devel/patches

中文文档：http://andelf.diandian.com/post/2013-05-22/40050677370

首先，如果我们的补丁是一个文件的话，可以将它们放置在openwrt/target/下面，这儿的文件一般情况下就是直接拷贝到build_dir中适当地地方去了，如下图。

而使用quilt制作的补丁文件，则是在需要修改一些Makefile或者Kconfig或者不是自己独有的文件情况下才需要的。

Working with patches

OpenWrt Buildroot integrates quilt for easy patch management. This document outlines some common patching tasks like adding a new patch or editing existing ones.

Prepare quilt configuration

In order to let quilt create patches in OpenWrts preferred format, a configuration file .quiltrc containing common diff and patch options must be created in the local home directory.

cat > ~/.quiltrc <<EOF
QUILT_DIFF_ARGS="--no-timestamps --no-index -pab --color=auto"
QUILT_REFRESH_ARGS="--no-timestamps --no-index -pab"
QUILT_PATCH_OPTS="--unified"
QUILT_DIFF_OPTS="-p"
EDITOR="nano"
EOF

EDITOR specifies the preferred editor for interactive patch editing
The other variables control the patch format property like a/, b/ directory names and no timestamps
FreeBSD does not support the --color=auto option and -pab must be written as -p ab

Adding a new patch

To add a completely new patch to an existing package example start with preparing the source directory:

make package/example/{clean,prepare} V=s QUILT=1

For host-side packages, you may want to detail the make target:

make package/example/host/{clean,prepare} V=s QUILT=1

This unpacks the source tarball and prepares existing patches as quilt patch series (if any). The verbose output will show where the source got extracted.

Change to the prepared source directory.

cd build_dir/target-*/example-*

Note : It can happen that you need to go one level lower as the source is extracted in build_dir/target-*/BUILD_VARIANT/example-* . This happens when multiple build variants of a package are defined in the Makefile.

Apply all existing patches using quilt push.

quilt push -a

Create a new, empty patch file with the quilt new command:

quilt new 010-main_code_fix.patch

The name should start with a number, followed by a hyphen and a very short description of what is changed
The choosen number should be higher than any existing patch - use quilt series to see the list of patches
The patch file name should be short but descriptive

After creating the empty patch, files to edit must be associated with it. The quilt add command can be used for that - once the file got added it can be edited as usual.
A shortcut for both adding a file and open it in an editor is the quilt edit command:

quilt edit src/main.c

src/main.c gets added to 010-main_code_fix.patch
The file is opened in the editor specified with EDITOR in .quiltrc

Repeat that for any file that needs to be edited.

After the changes are finished, they can be reviewed with the quilt diff command.

quilt diff

If the diff looks okay, proceed with quilt refresh to update the 010-main_code_fix.patch file with the changes made.

quilt refresh

Change back to the toplevel directory of the buildroot.

cd ../../../

To move the new patch file over to the buildroot, run update on the package:

make package/example/update V=s

Finally rebuild the package to test the changes:

make package/example/{clean,compile} package/index V=s

If problems occur, the patch needs to be edited again to solve the issues. Refer to the section below to learn how to edit existing patches.

Edit an existing patch

Start with preparing the source directory:

make package/example/{clean,prepare} V=s QUILT=1

Change to the prepared source directory.

cd build_dir/target-*/example-*

List the patches available:

quilt series

Advance to the patch that needs to be edited:

quilt push 010-main_code_fix.patch

When passing a valid patch filename to push, quilt will only apply the series until it reaches the specified patch
If unsure, use quilt series to see existing patches and quilt top to see the current position
If the current position is beyound the desired patch, use quilt pop to remove patches in the reverse order

Edit the patched files using the quilt edit command, repeat for every file that needs changes.

quilt edit src/main.c

Check which files are to be included in the patch:

quilt files

Review the changes with quilt diff.

quilt diff

If the diff looks okay, proceed with quilt refresh to update the current patch with the changes made.

quilt refresh

Change back to the toplevel diretory of the buildroot.

cd ../../../

To move the updated patch file over to the buildroot, run update on the package:

make package/example/update V=s

Finally rebuild the package to test the changes:

make package/example/{clean,compile} package/index V=s

Adding or editing kernel patches

The process for modifying kernel patches is the same as for packages, only the make targets and directories differ.
:!: For the kernel, an additional subdirectory for patches is used, generic/ contains patches common to all architectures and platform/ contains patches specific to the current target.

To prepare the kernel tree, use:

make target/linux/{clean,prepare} V=s QUILT=1

For Attitude Adjustment, the source tree is in the linux-architecture subdirectory:

cd build_dir/linux-*/linux-3.*

For Barrier Breaker (trunk), the source tree is in the target-architecture subdirectory (potentially with a subarch):

cd build_dir/target-*/linux-*/linux-3.*

Moving the changes back over to the buildroot tree from the build tree is done with:

make target/linux/update package/index V=s

( :!: Patches should be named with the correct prefix, platform/000-abc.patch or generic/000-abc.patch. If not the update may not work correctly.)

Afterwards, if we want to verify whether our patch is applied or not, we can go to the top level directory with

cd ../../../../

and preparing again the linux folder for some modification with

make target/linux/{clean,prepare} V=s QUILT=1

During this process all the applied patched will be shown, ours being among them, preceeded by generic/ or platform/ depending on what directory we placed the patch. Another way of retrieving the applied patches is through

quilt series

as explained on the previous sections, after having made make target/linux/{clean,prepare} …

Adding or editing toolchain patches

For example, gcc:

To prepare the tool tree, use:

make toolchain/gcc/{clean,prepare} V=99 QUILT=1

The source tree depends on chosen lib and gcc :

cd build_dir/toolchain-mips_r2_gcc-4.3.3+cs_uClibc-0.9.30.1/gcc-4.3.3

Refreshing the patches is done with:

make toolchain/gcc/update V=99

Refreshing patches

When a patched package (or kernel) is updated to a newer version, existing patches might not apply cleanly anymore and patch will report fuzz when applying them. To rebase the whole patch series the refresh make target can be used:

make package/example/refresh V=s

For kernels, use:

make target/linux/refresh V=s

Iteratively modify patches without cleaning the source tree

When implementing new changes, it is often required to edit patches multiple times. To speed up the process, it is possible to retain the prepared source tree between edit operations.

Initially prepare the source tree as documented above
Change to the prepared source directory
Advance to the patch needing changes
Edit the files and refresh the patch
Fully apply the remaining patches using quilt push -a (if any)
From the toplevel directory, run make package/example/{compile,install} or make target/linux/{compile,install} for kernels
Test the binary
If further changes are needed, repeat from step 2.
Finally run make package/example/update or make target/linux/update for kernels to copy the changes back to buildroot

为 OpenWrt 加入新设备支持 // Add New Profile To OpenWrt

最近折腾 TL-MR10U, 可直接刷 WR703N 固件, 不过 USB 不能供电, 网络, LED 正常. 所以需要修复下. 记录+教程.

假定已经有了完整 OpenWrt 开发环境. 包括编辑器, 配置好的 quilt 工具.

经过本人实践, 当前(20130522)在互联网上能找到的大部分教程都不靠谱, 或多或少有错误或者坑, 有的干脆就是错的.

配置开发环境

请参考其他文献设置开发环境. 前几篇恰好写过.

简单介绍下 quilt 工具, quilt 是用来管理代码树中的 patch 的, 嵌入式内核开发利器!

请通过软件包管理器安装 quilt. 然后写入以下配置文件到 ~/.quiltrc , 另外需要 export EDITOR="你编辑利器" .

QUILT_DIFF_ARGS="--no-timestamps --no-index -pab --color=auto"
QUILT_REFRESH_ARGS="--no-timestamps --no-index -pab"
QUILT_PATCH_OPTS="--unified"
QUILT_DIFF_OPTS="-p"
EDITOR="emacs --no-init --quick"

准备工作

假定 ~/openwrt 是你的开发目录, 建议直接在 git branch 下开发.

假设之前已经编译过 bin, 有完整的 .config 和 toolchain.

建立开发 branch: (git 教程自行脑补)

~/openwrt$ git checkout -b add-tl-mr10u-support

清理 tmp 目录!!!!!! 这个是大坑. 直接删除.

~/openwrt$ rm -rvf tmp/

修改 OpenWrt 代码

进入设备硬件目录:

~/openwrt$ cd target/linux/ar71xx

修改以下文件, 里面涉及到 TL-MR10U 固件中设备ID的部分, 是 0x00100101, 这个值从 tp-link 官方网站下载的固件中可以获得.

base-files/etc/diag.sh
base-files/etc/uci-defaults/02_network
base-files/lib/ar71xx.sh
base-files/lib/upgrade/platform.sh
config-3.8
generic/profiles/tp-link.mk
image/Makefile

新建文件: files/arch/mips/ath79/mach-tl-mr10u.c , 内容参考 TL-WR703N 设备的文件 mach-tl-wr703n.c, 修改所有出现 wr703n, WR703N 等等大小写混合的部分, emacs 无痛苦完成.

添加 Linux patch

这里就完成了 OpenWrt 的设备支持代码. 为了支持我们的设备, Linux 代码树的部分文件也需要做改动, OpenWrt 采用了 patch 的方式实现.

回退到根目录 ~/openwrt .

清理并准备 patch 树:

~/openwrt$ make target/linux/{clean,prepare} # 后面可加 V=s QUILT=1 参数, 表示静默无输出

进入内核代码目录(其中版本号可能与你的不一致):

~/openwrt$ cd build_dir/target-mips_r2_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.8.12/

这里就是内核代码树了, 里面的代码是已经打过所有 patch 的, 可以用 quilt push 检查看是不是这样:

$ quilt push
File series fully applied, ends at patch platform/902-unaligned_access_hacks.patch

这条输入也告诉我们, 当前最顶的 patch 是 platform/902 (这个是坑啊, 官方文档不带 platform 前缀, 是错的).

为我们的 TL-MR10U 新建个 patch:

$ quilt new platform/920-add-tl-mr10u-support.patch

选择的数字需要大于刚才的那个 902, 然后 quilt 会自动把这个 patch 设置为当前 patch, 所有的改动都针对这个 patch.

然后就是增加代码了

$ quilt edit arch/mips/ath79/Kconfig
$ quilt edit arch/mips/ath79/Makefile
$ quilt edit arch/mips/ath79/machtypes.h

至于怎么改, 参考这些文件里其他硬件的配置, 基本上说 copy TL-WR703N 的就可以了. 保证不重不漏.

然后验证下修改的内容:

$ quilt diff # 查看 diff
$ quilt refresh # 保存所有 diff 到 patch 文件

这个时候我们的 patch 文件还在 build_dir 里, 大概位置是 patches/platform/ 下. 需要同步到 OpenWrt 代码树.

# 退回到顶层工作目录, 执行:
~/openwrt$ make target/linux/update V=s

同步完成后, patch 文件会出现在 target/linux/ar71xx/patches-3.8/ 下.

固件工具代码修改

OpenWrt 包含一个 TP-LINK 固件小工具, tools/firmware-utils/src/mktplinkfw.c , 里面包含 TP-LINK 固件 bin 文件的结构和 md5 hash 验证算法.

修改内容参考 WR703N 就好.

查看效果

这里应该已经完成了所有操作. 可以编译了

# 再次记得, 删除 tmp 目录
~/openwrt$ rm -rvf tmp/
~/openwrt$ make menuconfig
.....
自己编译

如何修改刚刚的903补丁？

tf@ubuntu:~/projects/openwrt/build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.10.49$ quilt files platform/903-modify_spi_gpio_merlin.patch

arch/mips/ath79/Makefile

tf@ubuntu:~/projects/openwrt/build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.10.49$ quilt refresh
Patch platform/903-modify_spi_gpio_merlin.patch is unchanged

//由于Kconfig和Makefile已经在903补丁中的记录了，所以直接使用其它编辑器去修改也可以了。如果files命令时没有文件需要更新到补丁中去，那么需要先quilt edit之。

//这儿使用外部编辑器Geany编辑了Kconfig文件的select ATH79_DEV_SPI_GPIO，最末加上了标记 //merlin

对应用程序进行制作补丁patch

make package/utils/xxx/clean V=s

make package/utils/xxx/prepare V=s

这样还没有修改的代码就已经解压到build_dir中了，使用cd build_dir/target.../xxx/到达应用程序目录

使用quiltnew命令新建一个补丁

quilt new 101-test_add_comment.patch

使用quilt edit命令修改某个文件如src/main.c

quilt edit src/main.c

修改完成后保存退出

运行quilt diff看变化前后，

最后运行quilt refresh命令会生成101-test_add_comment.patch

将这个patch文件拷贝到package/utils/xxx/patch下面去，这样在下一次
