Primary LanguageC

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!!!

Below is all changes from tsl0922/padavan

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 13.2.0
    • musl 1.2.4
  • OpenWrt style package Makefile
  • Enabled kernel cgroups support
  • Fixed K2P led label names
  • Replaced udpxy with msd_lite
  • Replaced Web Console with ttyd
  • Upgraded libs and user packages
  • And a lot of package related fixes
  • ...

Compilation steps

  • Install dependencies

    # Debian/Ubuntu
sudo apt install unzip libtool-bin ccache curl cmake gperf gawk flex bison nano xxd \
    fakeroot kmod cpio bc zip 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 for building go programs 
      sudo rm -rf /usr/local/go
curl -fsSL https://go.dev/dl/go1.20.10.linux-amd64.tar.gz | sudo tar -C /usr/local -xz
echo "export PATH=\$PATH:/usr/local/go/bin" | sudo tee /etc/profile.d/go.sh
source /etc/profile.d/go.sh
go version
    • install nodejs for building AdGuardHome 
      sudo apt update
sudo apt install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_18.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list
sudo apt update
sudo apt install -y nodejs
node -v

  • 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
