padavan-4.4

This project is based on original rt-n56u with latest mtk 4.4.198 kernel, which is fetch from D-LINK GPL code.

Extra functions / changes

• Tune kernel configs (for NEWIFI / K2P only)
• Decline the load average over multiple-cores for compatiable with more old apps running well.
• Revise the MTD storage partition for 16M flash, the firmware size must be less than 10MB as possible.
• Revise the MTD storage partition for 32M flash, the firmware size has no change as before, but the storage size can have more than 15MB.
• Adding user/chinadns-ng , and fix shadowsocks + chinadns-ng using local domain whitellist.
• FRP supported (dynamically loaded)
• AP relay auto-daemon

SS/SSR

• Transparent proxy (iptables) wasn't cleaned completely, this issue is fixed.
• Adding DNSProxy , Local DNS integrated with SS/SSR
• Dnsmasq optimization specially for SS/SSR
• Resolve DNS pollution - Adding DNS i/p in china-route mode
• Fast-open option is enabled according to linux version

Compile notes

• Be careful: if you run the same workflow twice again , it could directly reload the previous Makefile from cache. so if you made change of Makefile , you will have to run a new workfolow!!!

Enhancements in this repo

• commits has beed rewritten on top of hanwckf/rt-n56u repo for better history tracking
• Optimized Makefiles and build scripts, added a toplevel Makefile
• Added ccache support, may save up to 50%+ build time
• Upgraded the toolchain and libc:
  • gcc 10.3.0

Compilation steps

• Install dependencies

  # Debian/Ubuntu
  sudo apt install unzip libtool-bin ccache curl cmake gperf gawk flex bison nano xxd \
      fakeroot kmod cpio git python3-docutils gettext automake autopoint \
      texinfo build-essential help2man pkg-config zlib1g-dev libgmp3-dev \
      libmpc-dev libmpfr-dev libncurses5-dev libltdl-dev wget libc-dev-bin

  Optional: install golang (and add it to PATH), if you are going to build go programs

• Clone source code

  git clone https://github.com/tsl0922/padavan.git

• Modify template file and start compiling

  # (Optional) Modify template file
  # vi trunk/configs/templates/K2P.config
  
  # Start compiling with: make PRODUCT_NAME
  make K2P
  
  # To build firmware for other devices, clean the tree after previous build
  make clean

• Driver modulde compilation

  Copy / Paste the below codes then put it in the ending of the Makefile in the driver package folder (e.g, mt76x2_ap) Assume that /work is the root path with padavan-4.4

  CROSS=/work/padavan-4.4/toolchain-mipsel/toolchain-4.4.x/bin/mipsel-linux-uclibc-
  KERNEL=/work/padavan-4.4/trunk/linux-4.4.x/
  STRIP=/work/padavan-4.4/toolchain-mipsel/toolchain-4.4.x/bin/mipsel-linux-uclibc-strip
  
  all:
        #make ARCH=mips CROSS_COMPILE=$(CROSS) -C $(KERNEL) SUBDIRS=$(PWD) modules
        $(STRIP) $(PWD)/$(RT_DRV_NAME).ko
  clean:
        make -C $(KERNEL) SUBDIRS=$(PWD) clean
