Preliminary Call-For-Testing: Cross-DSO CFI

Over the past year, HardenedBSD has been hard at work in integrating the Cross-DSO CFI implementation in llvm. We have reached a point where we can release an early (pre-alpha) public Call For Testing (CFT) of this work.

For reasons which will be described below, we recommend this CFT be used by those using root-on-ZFS with boot environments. We recommend testing in a dedicated boot environment.

This initial round of testing is best suited for development server installations. Production servers and desktops/laptops are not advised for testing at this time. We're looking for feedback on what works and doesn't work.


Control Flow Integrity, or CFI, is an exploit mitigation that aims to make it harder for an attacker to hijack the control flow of an executable image. llvm's CFI implementation provides forward-edge protection, meaning it protects call sites and non-return code branches. llvm includes basic and incomplete backward-edge protection via SafeStack.

CFI in llvm consists of two flavors:

1. Non-Cross-DSO CFI
2. Cross-DSO CFI

For over a year now, HardenedBSD has adopted non-Cross-DSO CFI in 12-CURRENT/amd64. Support for non-Cross-DSO CFI was added for 12-CURRENT/arm64 on 01 July 2018. Non-Cross-DSO CFI applies CFI to the applications themselves, but not on the shared objects they depend on. Cross-DSO CFI applies CFI to both applications and shared objects, enforcing CFI across shared object boundaries.

When an application or shared object is compiled, its source files typically get compiled first to intermediate object files. Enabling Cross-DSO CFI requires compiling and linking both static and shared libraries with Link Time Optimization (LTO). When LTO is enabled, these object files are no longer ELF object files, but rather LLVM IR bitcode object files.

Linking applications that have been compiled with LTO generally only requires ld.lld as the linker. Linking libraries that have been compiled with LTO requires switching certain compiler toolchain components to ones that understand LLVM IR bitcode. To prepare for Cross-DSO CFI, we switched ar, ranlib, nm, and objdump to their respective llvm compiler toolchain components. This gives us the ability to use LTO across-the-board for the HardenedBSD userland, with a few exceptions.

Note that because Cross-DSO CFI requires storing metadata regarding the shared library boundaries at runtime, Cross-DSO CFI requires ASLR and PaX NOEXEC at a minimum to be effective. If an attacker knows the address of the metadata pages, the attacker can first perform data-only attacks for later code execution/code reuse attacks. Similarily, if an attacker is able to mark non-executable, yet writable, pages as executable while still obeying CFI, (example: JIT compiled code) the attacker can still gain perform execution/code reuse attacks.

Known Issues And Limitations

There are a few known issues. Before we dive into the testing procedure, I would like to talk a bit about known regressions. Note that this list of known issues essentially also constitutes a "work-in-progress" and every known issue will be fixed prior to the
official launch of Cross-DSO CFI.

It seems llvm does not like statically compiling applications with LTO that have a mixture of C and C++ code. /sbin/devd is one of these applications. As such, when Cross-DSO CFI is enabled, devd is compiled as a Position-Independent Executable (PIE). Doing this breaks UFS systems where /usr is on a separate partition. We are currently looking into solving this issue to allow devd to be statically compiled again.

NO_SHARED is now unset in the tools build stage (aka, bootstrap-tools, cross-tools). This is related to the static compilation issue above. Unsetting NO_SHARED for to tools build stage is only a band-aid until we can resolve static compliation with LTO.

One goal of our Cross-DSO CFI integration work is to be able to support the cfi-icall scheme when dlopen(3) and dlsym(3)/dlfunc(3) is used. This means the runtime linker (RTLD), must be enhanced to know and care about the CFI runtime. This enhancement is not currently implemented, but is planned.

When Cross-DSO CFI is enabled, SafeStack is disabled. This is because compiling with Cross-DSO CFI brings in a second copy of the sanitizer runtime, violating the One Definition Rule (ODR). Resolving this issue should be straightforward: Unify the sanitizer runtime into a single common library that both Cross-DSO CFI and SafeStack can link against.

As of 07 Jun 2018, libpmc and friends are receiving a lot of code churn in upstream FreeBSD. The jevents application in lib/libpmc/pmu-events is used as a build tool to generate code. Enabling Cross-DSO CFI disables building PMC-related tools (libpmc and friends) due to the jevents application segfaulting during the build process.

When the installed world has Cross-DSO CFI enabled, performing a buildworld with Cross-DSO CFI disabled fails. This is somewhat related to the static compilation issue described above.

Linking with Cross-DSO CFI can cause lld to use an extremely large amount of memory. For each parallel build job, budget around 15GB of memory for the linker.

Due to the issues discussed above, this CFT is applicable to users who either use ZFS or where /usr is contained within the root filesystem.

Procedure For Testing

Use git to clone locally the HardenedBSD Playground repo. The instructions below assume using /usr/src as the location for the source tree. It also blows away your existing source tree, if it exists. If you want to keep your existing source tree, feel free to
modify the steps below to your liking.

Due to the complexity of building Cross-DSO CFI, the buildworld step must be completed twice: once without Cross-DSO CFI and a second time with. The non-Cross-DSO CFI world must be installed prior to performing the second build. As noted above, we will work to ensure this doesn't need to happen later.

These instructions make the following assumptions:

1. The root filesystem is on ZFS, with the proper layout for ZFS Boot Environments.
2. The beadm package is installed.
3. The existing installation is running 12-CURRENT on amd64.

# cd /usr
# rm -rf src
# git clone \
# cd src
# git checkout -b hardened/current/cross-dso-cfi \
# make -sj$(sysctl -n hw.ncpu) buildworld buildkernel
# beadm create cfi-01
# beadm mount cfi-01 /tmp/newbe
# make -s installworld installkernel DESTDIR=/tmp/newbe
# mergemaster -iFUD /tmp/newbe
# beadm umount cfi-01
# beadm activate cfi-01
# shutdown -r now

Binary Updates

We will provide binary updates in base for the hardened/current/cross-dso-cfi feature branch on amd64 until this work gets merged into hardened/current/master. Take a look at Appendix A for a sample hbsd-update.conf configuration file for the Cross-DSO CFI work.

Future Work

We're not done, yet! There's still plenty of work to do. Of upmost importance is fixing static compilation with LTO enabled. Without it, statically-linked applications will crash. devd can go back to being a statically-linked application and users with /usr on a separate non-ZFS filesystem will be able to take advantage of Cross-DSO CFI.

Secondly, we need to re-integrate SafeStack, giving us backward-edge protections once again.

Third up is integration with the RTLD. Without it, we still need to disable the cfi-icall scheme for applications that make use of dlopen(3)+dlsym(3)/dlfunc(3).

Given that we're in uncharted territory, we will likely find other issues. We will keep the community updated and informed. Once all issues have been resolved, we will work on integration with ports.

We need to ensure buildworld works with the various CFI (MK_CFI and MK_CROSS_DSO_CFI) options toggled, regardless of installed world state.

Given the tremendous memory requirements, HardenedBSD may not be able to apply Cross-DSO CFI across the entire package repository. The current amd64 package building system is a dual Xeon system with eight cores per CPU (sixteen cores total), 192GB RAM, and 64GB swap. Without Cross-DSO CFI, building the package repo for amd64 takes around 82 hours to complete using all sixteen cores. With Cross-DSO CFI enabled, the package build server eventually runs out of swap using only eight of the sixteen cores.

Though we plan to support Cross-DSO CFI in arm64, amd64 will be the primary development platform until the major issues are worked out. The sanitizer framework needs to be updated to take FreeBSD/HardenedBSD into account on arm64. As of 14 July 2018, the llvm sanitizer framework does not support FreeBSD/arm64. With time, we plan to change that.

HardenedBSD may very well be the first UNIX-like operating system with full Cross-DSO CFI integration across its entire base operating system userland.

Mid-July HardenedBSD Foundation Status

On 09 July 2018, the HardenedBSD Foundation Board of Directors held the kick-off meeting to start organizing the Foundation. The following people attended the kick-off meeting:

1. Shawn Webb (in person)
2. George Saylor (in person)
3. Ben Welch (in person)
4. Virginia Suydan (in person)
5. Ben La Monica (phone)
6. Dean Freeman (phone)
7. Christian Severt (phone)

We discussed the very first steps that need to be taken to organize the HardenedBSD Foundation as a 501(c)(3) not-for-profit organization in the US. We determined we could file a 1023EZ instead of the full-blown 1023. This will help speed the process up drastically.

The steps are laid out as follows:

  1. Register a Post Office Box (PO Box) (completed on 10 Jul 2018).
  2. Register The HardenedBSD Foundation as a tax-exempt nonstock corporation in the state of Maryland (started on 10 Jul 2018, submitted on 18 Jul 2018, granted 20 Jul 2018).
  3. Obtain a federal tax ID (obtained 20 Jul 2018).
  4. Close the current bank account and create a new one using the federal tax ID (completed on 20 Jul 2018).
  5. File the 1023EZ paperwork with the federal government (started on 20 Jul 2018, submitted 28 Aug 2018).
  6. Hire an attorney to help draft the organization bylaws.

Each of the steps must be done serially and in order.

We added Christian Severt, who is on Emerald Onion's Board of Directors, to the HardenedBSD Foundation Board of Directors as an advisor. He was foundational in getting Emerald Onion their 501(c)(3) tax-exempt, not-for-profit status and has really good insight. Additionally, he's going to help HardenedBSD coordinate hosting services, figuring out the best deals for us.

We promoted George Saylor to Vice President and changed Shawn Webb's title to President and Director. This is to help resolve potential concerns both the state and federal agencies might have with an organization having only a single President role.

We hope to be granted our 501(c)(3) status before the end of the year, though that may be subject to change. We are excited for the formation of the HardenedBSD Foundation, which will open up new opportunities not otherwise available to HardenedBSD.

June HardenedBSD Foundation Update

We at HardenedBSD are working towards starting up a 501(c)(3) not-for-profit organization in the USA. Setting up this organization will allow future donations to be tax deductible. We've made progress and would like to share with you the current state of affairs.

We have identified, sent invitations out, and received acceptance letters from seven people who will serve on the HardenedBSD Foundation Board of Directors. You can find their bios below. In the latter half of June 2018 or the beginning half of July 2018, we will meet for the first time as a board and formally begin the process of creating the documentation needed to submit to the local, state, and federal tax services.

Here's a brief introduction to those who will serve on the board:

  1. W. Dean Freeman (Advisor): Dean has ten years of professional experience with deploying and securing Unix and networking systems, including assessing systems security for government certification and assessing the efficacy of security products. He was introduced to Unix via FreeBSD 2.2.8 on an ISP shell account as a teenager. Formerly, he was the Snort port maintainer for FreeBSD while working in the Sourcefire VRT, and has contributed entropy-related patches to the FreeBSD and HardenedBSD projects -- a topic on which he presented at vBSDCon 2017.
  2. Ben La Monica (Advisor): Ben is a Senior Technology Manager of Software Engineering at Morningstar, Inc and has been developing software for over 15 years in a variety of languages. He advocates open source software and enjoys tinkering with electronics and home automation.
  3. George Saylor (Vice President): George is a Technical Directory at G2, Inc. Mr. Saylor has over 28 years of information systems and security experience in a broad range of disciplines. His core focus areas are automation and standards in the event correlation space as well as penetration and exploitoation of computer systems. Mr Saylor was also a co-founder of the OpenSCAP project.
  4. Christian Severt (Advisor): Christian is an information security engineer. He served in the U.S. Navy administering classified Command, Control, Communication, Computers & Intelligence (C4I) systems. Christian also volunteers with the Seattle Privacy Coalition.
  5. Virginia Suydan (Treasury, secretary, and general administrator): Accountant and general administrator for the HardenedBSD Foundation. She has worked with Shawn Webb for tax and accounting purposes for over six years.
  6. Shawn Webb (President and Director): Co-founder of HardenedBSD and all-around infosec wonk. He has worked and played in the infosec industry, doing both offensive and defensive research, for around fifteen years. He loves open source technologies and likes to frustrate the bad guys.
  7. Ben Welch (Advisor): Ben is currently a Security Engineer at G2, Inc. He graduated from Pennsylvania College of Technology with a Bachelors in Information Assurance and Security. Ben likes long walks, beaches, candlelight dinners, and attending various conferences like BSides and ShmooCon.
