PS4Link Library Updated by BigBoss with LDR Creation and More!

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

  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
  

  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
  

  mkdir build
  cd build

  Now prepare configuration cmake and python needed
  

  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
  

  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:
  

  ./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:
  

  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:
  

  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
  

  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:
  

  cd libdebugnet
  make
  make install
  cd ../..

  compile and install libps4link it will let fio host requests and commands support
  

  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
  

  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:
  

  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.
  

  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 at the same time if you load after payload.elf
  
  let's go to compile our elf samples
  

  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
  

  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:
  

  http://ipofyourserver:5350

  at stage 5 you will have ps4link waiting for commands and you will see output in yout mac/pc

  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
  

  socat udp-recv:18194 stdout

  after load ps4link on ps4 we will see logs from debugnet library and information about threads created by ps4link

well if you can be honest about what you want thats fair but do take into consideration more can be done that leverages the webkit exploit to make things for the end user a bit more fun but at the same time give them a chance to tinker should they need to do so

 

[Space Monkey]

....is backups the only thing ppl want ?...
Smh...
It's open source for a reason..

One can compare PS4 with an high end sports car; researchers wants to race with it, developers want to show off with, and some want to use only for commute (play games).

I am too old/busy with work to learn tinker with my PS4. I, two, want to use the jailbreak for backups ad for custom apps made from developers like u and be grateful for all the work.

grateful is the only thing any dev has asked for.
give yourself a pat on the back for being honest and knowing that its hard work
that accomplishes anything. few are this thankful and/or honest.
First off,I would like to say i dont hate end users
but i always loved doing what i do
and its all i really i live for
all things achieved are possible
but some times some of us who work hard for sucess dont necessarily
release, communicate, or at times
even want a social life
when you dedicate yourself to something you love
you make sacrifices for a better life

Grateful is the only thing the end users can do; and, a bit of donation here and there.

Ungrateful pricks should be shot twice in the head in my opinion.

These days pirates are blamed for leeching and not contributing anything. I say people are wrong about pirates. Once a developer releases an app, it is us, the pirates, who come up with bug reports for the developer to polish their app. Since the developer has no time to cater 1000's of question that pop up on the net regarding problems one is facing, It is us, the pirates, who take up on our shoulders and help the community to resolve them. Few of those times developers take from our solutions and integrate it in their apps. Yet pirates are blamed to the core.

I not saying that pirates are great but hey we are not as bad as the people perceive us and we have our own ways and methods of contributing to community.

You're not alone, I wish I had more freetime to tinker these days but alas life gets in the way more often than not

The possibilities are endless with a little LLVM now

Honestly answer:Yes
I think most of the people(not developers)(include me) in the scene want backups so they can play games.

Uggg I was going to stay out of this but I respectfully disagree. I believe a majority of folks are like me and simply want to be able to play backups so the original disc is safe. I had no intention of buying a ps4 until it was hacked but one fell in my lap a year ago. I was quite content playing my flashed 360 and chipped ps2(that was a PIA). I like the idea of going all digital but that has it's problems also.

If you look at the past game & console sales went up after they were hacked

I know first post so chew me up if you wish

I'm all about backing up my investments. I'm also for preserving HARD COPIES. Going all digital will not go well. They will have too many GOD-MODE powers to ban you or keep you from accessing your content.

The bold above is what I disagree with 100%. Most don't even have the original discs for games. There's not many gamers on CFW that involve playing true backups from it!
