Since the last revision, PlayStation 4 developer BigBoss has updated the PS4Link library which allows PS4 to communicate and utilize a host file system with the PS4Client host tool.

According to the developer, PS4Link is now updated with ldr creation and information to do it yourself :)

Download: ps4link-master.zip / PS4Link GIT

From the ReadMe file: PS4LINK FOR PS4

What does this do?

PS4Link is a group of tools (libps4link, libdebugnet, ps4sh) for PS4 and host. It is the same method that we used in ps2dev days, so basically it is the same protocol than ps2link and ps2client have been using since 2003.

Functions available are defined like native sce functions so it is easy for homebrew developer to use these new functions:

FILEIO functions
Code:
  int ps4LinkOpen(const char *file, int flags, int mode);
  int ps4LinkClose(int fd);
  int ps4LinkRead(int fd, void *data, size_t size);
  int ps4LinkWrite(int fd, const void *data, size_t size);
  int ps4LinkLseek(int fd, int offset, int whence);
  int ps4LinkRemove(const char *file);
  int ps4LinkMkdir(const char *dirname, int mode);
  int ps4LinkRmdir(const char *dirname);
  int ps4LinkDopen(const char *dirname);
  int ps4LinkDread(int fd, struct dirent *dir);
  int ps4LinkDclose(int fd);
Remote Commands functions

1) execelf

This command let you load and exec elf files compiled with libps4. Check samples directory.

2) execsprx

Right now do nothing

3) execwhoami

Show you uid and gid

4) execshowdir

Let you list filenames in directory. With ftp server you will not need it

5) exitps4

Try to close ps4link resources. If you try to run ps4sh again when all is released you will get a messager saying that it can't connect. Now you can leave ps4 browser.

check ps4link_internal.h and commands.c to see how can you implements new commands

How do I use it?

1) Configure your environment:

You will need:
  • [clang] 3.7 or upper i tested it on freebsd and osx. For osx :

    For osx only (you will not need this for freebsd):

    Downloading clang
    Code:
    cd /usr/local/ps4dev/git
    mkdir crossllvm
    cd crossllvm
    git clone http://llvm.org/git/llvm.git
    cd llvm/tools
    git clone http://llvm.org/git/clang.git
    git clone http://llvm.org/git/lld.git
    cd ../projects
    git clone http://llvm.org/git/compiler-rt.git
    cd ../..
    You must create build directory outside of llvm
    Code:
    mkdir build
    cd build
    Now prepare configuration cmake and python needed
    Code:
    cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/ps4dev/toolchain -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_DEFAULT_TARGET_TRIPLE=x86_64-scei-ps4 -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCOMPILER_RT_BUILD_BUILTINS:BOOL=OFF -DCOMPILER_RT_BUILD_SANITIZERS:BOOL=OFF -DCOMPILER_RT_CAN_EXECUTE_TESTS:BOOL=OFF -DCOMPILER_RT_INCLUDE_TESTS:BOOL=OFF -DLLVM_TOOL_COMPILER_RT_BUILD:BOOL=OFF  -DCLANG_BUILD_EXAMPLES:BOOL=ON -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_C_FLAGS="-Wdocumentation -Wno-documentation-deprecated-sync" -DCMAKE_CXX_FLAGS="-std=c++11 -Wdocumentation -Wno-documentation-deprecated-sync" -DLLVM_LIT_ARGS="-v" ../llvm
    Compiling and install
    Code:
    cmake --build .
    cmake --build . --target install
    Fine a fresh clang 3.8 with the same compiling option from Sony. However Sony is using propietary linker so we need a valid linker for osx(freebsd has not this problem already has one).

    i downloaded binutils 2.25 and compile it with:
    Code:
    ./configure --prefix="$PS4DEV/host-osx" --target="x86_64-pc-freebsd9" \
      --disable-nls \
      --disable-dependency-tracking \
      --disable-werror \
      --enable-ld \
      --enable-lto \
      --enable-plugins \
      --enable-poison-system-directories
    make
    make install
    to avoid use osx native tools add this to your ps4dev.sh environment script only for osx using my configuration: PATH=$PS4DEV/host-osx/x86_64-pc-freebsd9/bin:$PS4DEV/toolchain/bin:$PATH

    Also if clang is searching for ps4-ld:
    Code:
    cd /usr/local/ps4dev/host-osx/x86_64-pc-freebsd9/bin
    cp ld ps4-ld
    now we can compile valid elf for ps4 from osx :)
  • libps4 library It is the base *** for ps4dev
  • elfldr basic loader It is the basic loader for ps4dev

    2) Declare variables and install libps4

    You can use a script with your environment variables. I like to use /usr/local/ps4dev/ps4dev.sh its content is:
    Code:
    PS4DEV=/usr/local/ps4dev;export PS4DEV
    libps4=$PS4DEV/libps4;export libps4
    COMPILER=clang37;export COMPILER
    
    cd /usr/local/ps4dev
    mkdir git
    mkdir libps4
    cd git
    git clone http://github.com/ps4dev/libps4
    cd libps4
    make
    cp -frv include $PS4DEV/libps4
    cp -frv make $PS4DEV/libps4
    cp -frv lib $PS4DEV/libps4
    cp crt0.s $PS4DEV/libps4
    3) PS4link
    Code:
    cd /usr/local/ps4dev/git
    git clone http://github.com/psxdev/ps4link
    cd ps4link
    compile and instal libdebugnet it will let to use udp logging to your own elf files and libraries:
    Code:
    cd libdebugnet
    make
    make install
    cd ../..
    compile and install libps4link it will let fio host requests and commands support
    Code:
    cd libps4link
    make
    make install
    Customize your pc/mac ip configuration if you need in /usr/local/ps4dev/git/ps4link/ps4link/source/main.c in ps4LinkInit call. You must use your pc/mac ip configuration in first parameter.

    create ps4link loader based on elfldr
    Code:
    cd ../
    ls
    LICENSE       elfldr      libps4link  ps4sh
    README.md libdebugnet ps4link     samples
    cd elfldr
    ./copy_ps4link_sources.sh
    make
    Now you have a ldr.js file in /usr/local/ps4dev/git/ps4link/elfldr/local/ldr with ps4link embed in it.

    To run webkit exploit you will need load index.html from directory local. Publish content from directory local in your web server or:
    Code:
    cd /usr/local/ps4dev/git/ps4link/eldldr/local
    node server.js
    Serving directory /usr/local/ps4dev/git/ps4link/elfldr/local on port 5350
    Now you have ready to run ps4link from your PlayStation 4

    4) Compile ps4sh

    ps4sh will let you speak with ps4link. It is based on pksh tools that we used in ps2dev days and credit goes to all people involved in its developments, greets to all of them.
    Code:
    change dst_ip for your PlayStation 4 ip at /usr/local/ps4dev/git/ps4link/ps4sh/src/ps4sh.c
    
    cd /usr/local/ps4dev/git/ps4link/ps4sh
    make
    5) Compile samples :) 3 samples are included sample, payload and ps4ftp

    sample is a very basic example it will receive debugnet conf from our ps4link, display some messages and exit.

    payload is a dlclose poc, it will give you root privileges, prison break and full file access and exit. After load it ps4link will have uid and gid 0 , WARNING use it under your own risk

    ps4ftp is based on xerpi ftp code and it will be give you a ftp server in your PlayStation 4, it can run with your game running :p at the same time if you load after payload.elf

    let's go to compile our elf samples
    Code:
    cd /usr/local/ps4dev/git/ps4link/samples
    cd sample
    make
    cp bin/sample.elf /usr/local/ps4dev/git/ps4link/ps4sh/bin
    cd ..
    cd payload
    make
    cp bin/payload.elf /usr/local/ps4dev/git/ps4link/ps4sh/bin
    cd ..
    cd ps4ftp
    make
    cp bin/ps4ftp.elf /usr/local/ps4dev/git/ps4link/ps4sh/bin
    Ok our samples elf files are ready to use in your PlayStation 4, switch on your console :)

    6) Webkit ps4link loader

    First to see initial logs execute in your pc/mac
    Code:
    socat udp-recv:18194 stdout
    Open your PlayStation 4 browser. Open you local directory content, for example if you use node server.js option use the following url:
    Code:
    http://ipofyourserver:5350
    at stage 5 you will have ps4link waiting for commands and you will see output in yout mac/pc
    Code:
    [PS4][INFO]: debugnet initialized

    [PS4][DEBUG]: [PS4LINK] Command listener waiting for commands...
    ^C
    You are ready to load your elf files...

    Next step show you a full session executing commands and loading samples.

    7) Session example using ps4link

    First to see initial logs before open url in PlayStation 4 browser
    Code:
    socat udp-recv:18194 stdout
    after load ps4link on ps4 we will see logs from debugnet library and information about threads created by ps4link
    Code:
    [PS4][INFO]: debugnet initialized
    [PS4][INFO]: Copyright (C) 2010,2016 Antonio Jose Ramos Marquez aka bigboss @psxdev

    [PS4][DEBUG]: [PS4LINK] Created ps4link_commands_sock: 87
    [PS4][DEBUG]: [PS4LINK] Command listener waiting for commands...
    ^C
    Now it's time to use ps4sh tool from mac/pc. Close socat with control-c
    Code:
    cd /usr/local/ps4dev/git/ps4link/ps4sh/bin
    ./ps4sh
    ps4sh version 1.0
    /Users/bigboss/.ps4shrc: No such file or directory
