HardenedBSD June 2023 Status Report

I'm a few days late to June's status report. But I have extremely good news. The development and build infrastructure is back online! All of our equipment made it safe and sound to Colorado. I'm currently being serenaded by the hum of the infrastructure in my home office.

If you cannot reach any bit of our public infrastructure, please let me know. There's a chance we may bring more servers online, depending on power availability and stability.

In addition to moving across the country, here's what happened in the src tree:

  1. Process tracing a process that has entered capabilities mode (aka, it successfully called `cap_enter(2)`) is now prohibited by default. A new per-jail sysctl tunable, `hardening.prohibit_ptrace_capsicum`, has been added. System administrators can also use `hbsdcontrol(8)` to toggle the restriction on a per-application basis.
  2. Some llvm work. FreeBSD imported llvm 16 into base. We needed to fix a few things regarding llvm16.

In ports:

  1. First-time patch submitter, vujo, disabled RELRO for editors/vscode.

HardenedBSD May 2023 Status Report

May 2023 has been a very busy month behind-the-scenes here at HardenedBSD. I want to start off, though, by talking about infrastructure downtime as it's the most important take-away from this status report.

On 03 June 2023, in preparation for our move to Colorado, I will take down the following servers (hosted out of my home):

  1. GitLab ( https://git.hardenedbsd.org/ )
  2. The main installers mirror ( https://installers.hardenedbsd.org/pub )
  3. The package build servers
  4. The OS and update build servers
  5. The Tor Onion Service nodes

The last pre-move builds will start tomorrow on 01 June 2023. They should complete by 02 June 2023. The builds will be accessible via our two mirrors. The link to the list of up-to-date HardenedBSD mirrors is: https://hardenedbsd.org/content/mirrors

We're grateful for those who provide mirrors. You ensure that HardenedBSD's installers (and hopefully one day: packages) are available regardless of our own infrastructure. The project, and I'm sure the entire community, thanks you.

At the time of writing this status report, we have a tentative temporary hosting solution with limited bandwidth capabilities. We're evaluating multiple hosting possibilities, with this tentative temporary hosting solution being only a backup in case those other options don't pan out. We do not have an ETA for bringing the infrastructure back online.

Now, let's get on with the fun stuff! The HardenedBSD Foundation is now fully registered in Colorado! We're moving the headquarters from Maryland to Colorado while still maintaining a presence my Maryland. Keeping a Maryland presence allows us to continue serving local communities. For those curious, our Colorado registration can be found at: https://www.coloradosos.gov/ccsa/ViewReports.do?ceId=325482

We will soon update the US federal side, the completion of which finishes the move to Colorado. The HardenedBSD Foundation Board of Directors has been a great help in supporting the move.

And now, in the src tree:

  1. Shawn fixed NULL pointer derefs in the following portions of the kernel:
    • mrsas(4)
    • powerpc code
    • NVIDIA Tegra CPU Frequency code <- integer overflow, too
    • iw_cxgbe
    • drm2 <- integer overflow, too
    • hdspe-pcm
    • linsysfs(5)
    • beri's virtio support <- integer overflow, too
    • firewire(4)
    • qnnxe(4)
    • axgbe pci code <- integer overflows, too
    • mmc(4)
  2. On 14-CURRENT (and soon in hbsdfw), SHM hardening places restricitons on what can be done with the shared memory subsystem (see `shm_open(2)`.) This feature is launching with one technique (with more planned):
    • Use of `shm_open(2)/__sys_shm_open2` system calls is prohibited when:
      1. The `hardening.harden_shm` sysctl tunable is enabled;
      2. The process has not opted out of the feature;
      3. The process has entered capability mode (aka, Capsicum mode)
  3. FreeBSD introduced an old vulnerability, the infamous (argc == 0) CVE, but this time in the linuxulator. Shawn ensured that HardenedBSD remains invulnerable.
  4. Shawn fixed the 14-CURRENT builds by fixing a FreeBSD commit for building ELF Toolchain's `strings(1)` utility. By default, we use llvm's.

And in ports:

  1. MrUnix disabled the JIT and re-enabled MPROTECT for www/ungoogled-chromium

In last month's status report, I mentioned that I decided to punish myself by running HardenedBSD 14-CURRENT/amd64 with Cross-DSO CFI enabled for base userland on my primary laptop, even during this move to Colorado. Shawn is happy to report that two months in, and he's still rocking (and keeping up-to-date with) Cross-DSO CFI! :-)

As a reminder, we mirror our src and ports repos on GitHub. They will remain available (and updated as best as I can). Links below.

HardenedBSD April 2023 Status Report

April was busy from an administrative perspective, with me working to get the Foundation and the Project ready to move to Colorado. We have around 90% of what we need to file as a not-for-profit, tax-exempt charitable organization in Colorado. We're hoping to file by the end of 05 May 2023.

Once the Colorado organization is live, we'll switch the federal side to point the headquarters to the new, yet-to-be-determined Colorado address. I believe once that's done, we should be fully re-headquartered.

On 02 June 2023, I plan to do our last pre-move code sync. Remember, we provide read-only mirrors on GitHub (listed below) for our base and ports repositories.

On 03 June 2023, I plan to take the build infrastructure down for the move. We do not have an ETA for bringing it back up, but bringing up the infrastructure will be of highest priority. I'll be unpacking and powering on equipment before I unpack the kitchen. ;-)

Package repos will remain online even during the move. However, we will need to rely on our mirrors (link to the mirrors page below) to provide installation media. We are grateful for those who provide public mirrors.

Please reach out to us (core@hardenedbsd.org or netops@hardenedbsd.org) to get set up as a public mirror if you're interested. The sooner we can get new mirrors launched, the better poised we (the community) are for the move.

Let's get to the changes! In src:

  1. The installer will no longer ask to install the kernel debug distset. We do not support downloading the distsets at install time.
  2. FreeBSD kept trying various methods to enable Netlink support in the kernel. Given our concerns about Netlink's current code quality, we kept trying to follow in disabling Netlink by default.

In ports:

  1. MrUnix disabled the JIT in www/chromium and www/iridium, which switches the default javascript engine to one that's PaX MPROTECT-safe.
  2. MrUnix fixed multimedia/obs-studio
  3. MrUnix disabled PaX MPROTECT for www/node18
  4. MrUnix disabled PaX MPROTECT for www/node19
  5. MrUnix disabled PaX PAGEEXEC for devel/valgrind and devel/valgrind-devel

I have decided to punish myself by running HardenedBSD 14-CURRENT/amd64 with Cross-DSO CFI enabled for base on my primary laptop. My goal here is to see if I can effectuate the move to Colorado while running with Cross-DSO CFI. The first problem I experienced was i3wm, which would crash upon launching any command. Interestintly, xfce4 mostly works. The xfce4-panel application crashes, but the rest of xfce4 seems to work just fine and dandy.

We are grateful for the past, present, and future contributions from the community. There are many ways to contribute to the project. You don't have to be a security expert or even know how to program! We appreciate contributions in any form they come in, like advocacy, monetary donations, documentation, bug reports, etc. Thank you for making this project possible!

HardenedBSD March 2023 Status Report

I missed February's status report, so March's will contain both months. Let's start off with a bit of personal news, though. My wife, our two dogs, and I are officially moving to Colorado! Our move-out date is June 10th.

Additionally, my wife and I have set up a GoFundMe. Please note that donations to the GoFundMe are NOT eligible for tax deductions, but donations directly to The HardenedBSD Foundation are.

I plan to purchase a number of pieces of equipment to help with the move to make sure that the equipment arrives intact. HardenedBSD could still definitely use your continued support, for which I and the rest of the community are grateful.

This move obviously will impact the project. I've spent most of March working on getting the project and the HardenedBSD Foundation ready administratively for the move. There's only three things left to do, and the Foundation will have officially moved headquarters from Maryland to Colorado. We will be leaving a skeleton organziation in Maryland in case we want to do Maryland-specific things. For example, there could be some future Maryland-specific fundraiser or service opportunity.

I plan to keep the infrastructure online as long as I can. I suspect the infrastructure will be taken offline on around 09 June 2023, when we start loading the truck. However, there's a chance that the infrastructure will be taken down up to a week in advance. Since we don't know where we're going to land, I cannot provide an ETA as to when the infrastructure would be back online.

We plan to rent only for up to one year at most. We want to explore Colorado a bit to find out where we want to plant our roots. So there will be another infrastructure-disrupting move on the inside of a year from June. Hopefully that move will be to the home in which we retire in two-ish decades. I'm going to make having full self-hosting capabilities a priority in our "forever" home. So, now, let's get on to the src and ports updates since the end of January 2023.

In src:

  1. tarfs is marked as insecure.
  2. tarfs has been opted into -ftrivial-var-auto-init=zero.
  3. geli has been opted into -ftrivial-var-auto-init=zero.
  4. FreeBSD merged llvm 15 into base, so some fixups were needed on our side.
  5. pf has been opted into -ftrivial-var-auto-init=zero.
  6. pfsync has been opted into -ftrivial-var-auto-init=zero.
  7. pflog has been opted into -ftrivial-var-auto-init=zero.
  8. Default net.inet6.icmp6.nodeinfo to 0. This prevents host information disclosures via ICMP6.
  9. Added some safty nets in the new netlink code
  10. Dislabed netlink multiple times in multiple ways, chasing FreeBSD's continued attempt at enabling netlink by default.
  11. cfi-icall has been disabled for various NFS-related applications.
  12. The TTY pushback vulnerability has been mitigated by hardening the TIOCSTI ioctl. Attempts to use the TIOCSTI ioctl node will fail with EPERM. A new per-jail sysctl tunable (`hardening.harden_tty`) has been added, defaulted to 1.
  13. The default packet TTL is randomized at boot-time, with a minimum of 32 hops. This feature is controlled by the new `HBSD_RESIST_FINGERPRINTING` kernel option, which is enabled by default. This feature can help with resisting fingerprinting attacks and preventing information leaks.
  14. 0x1eef fixed a few typos in libhbsdcontrol.3.

SPECIAL NOTE ON ITEM 13: This has the potential for network disruption. I probably need to adjust the minimum hops as 32 might be too limiting. Please reach out to me directly if you are unable to get to resources that you used to get to. The sysctl node being set is `net.inet.ip.ttl`, and that can be adjusted anytime post-boot.

In ports:

  1. DTRACE is disabled for www/node18.
  2. CFI is disabled for security/sudo.
  3. java/openjdk11 was fixed.
  4. MrUNIX disabled PaX MPROTECT for bin/kdeconnect-app
  5. MrUNIX disabled PaX MPROTECT for multimedia/mpv
  6. MrUNIX disabled PaX MPROTECT for www/librewolf
  7. MrUNIX disabled PaX MPROTECT and PaX PAGEEXEC for www/otter-browser
  8. MrUNIX disabled PaX MPROTECT for www/tor-browser
  9. MrUNIX enabled CFI and SafeStack for x11-wm/i3-gaps

HardenedBSD Firewall (hbsdfw)

hbsdfw is a fork of OPNsense based on HardenedBSD 13-STABLE.

A new build of hbsdfw is out. We still don't provide official in-place updatesupport, so your update process should be as follows:

1. Backup your existing config
2. Reinstall with the new image
3. Restore the config

The default username and password is:

Username: root
Password: hbsdfw

HardenedBSD Infrastructure

We now regularly build 13-STABLE and 14-CURRENT, on the first and fourteenth day of each month. The 13-STABLE and 14-CURRENT package build jobs are still kicked off manually, but usually follow on the same day or the day after the installation media build.

We're looking for more mirrors for the installation media. We're grateful for those who currently run public mirrors.

HardenedBSD January 2023 Status Report

It has been a number of months since the last status report. I got really sick in November/December and am now recovering from COVID. Fun! Regardless, there have been a ton of enhancements and goings on in the project.

In src:

  1. devd(8) is now compiled as a PIE default
  2. FreeBSD commit 140ceb5d956bb8795a77c23d3fd5ef047b0f3c68 introduced the ability to easily force a remote process to perform a syscal (`ptrace(PT_SC_REMOTE)`). This is restricted by the `hardening.prohibit_ptrace_syscall` sysctl node by default. While an attacker can force the remote process to execute syscalls regardless, I think exposing an API to make this easier is not attractive.
  3. The netlink(4) module is marked as insecure. FreeBSD recently landed support for basic netlink socket support. However, the implementation quality seems to be sub-par and has me worried about security implications. FreeBSD has enabled netlink by default in the GENERIC kernel config (from which we inherit). I've disabled it default in the HardenedBSD kernel configs.
  4. I fixed a number of potential NULL deref vulnerabilities in netlink(4).
  5. I fixed a bug in the insecure kmod loading enforcement code.
  6. I fixed a number of code consitency issues in netlink(4).
  7. I introduced a new feature: malloc(9) hardening. A new kernel option, PAX_HARDEN_KMALLOC, enables all malloc(9) hardening features by default. The only feature implemented currently is zeroing allocations on creation and free. To enable allocation zeroing without having to compile a custom kernel, set the `hardening.kmalloc_zero` sysctl tunable node to 1. It is disabled by default due to obvious performance impacts.
  8. Kernel modules can now opt-in to -ftrivial-var-auto-init=zero. Kernel modules currently opted in:
    • virtio-net
    • netlink
    • zfs
    • linuxkpi
    • tmpfs
  9. uuidgen(1) now defaults to generating UUIDv4 identifiers. A new option, -R, provides backwards compatibility for generating UUIDv1 identifiers.

Ports hasn't seen much change, just regular maintenance. So not much to report there.

The infrastructure is slowly coming back online. I'm now hosting GitLab and one build server at home. I'm rewriting the build scripts from scratch, tying together the `hbsd-update` artifacts and the installation media together. I'm about 99% done with that. Once that reaches 100% (hopefully by the end of this week), I will reach out to those who showed desire to host public mirrors of our builds.

I suspect my electricity bills are going to go up by around $250USD/month. Once I'm done with the infrastructure work, I will sit down and switch to the administrative side of the house.

Here are my goals for February 2023:

  1. Write a 2023 project roadmap with firm donation goals, coordinating this with the HardenedBSD Foundation Board of Directors.
  2. Send out donation receipts for 2022 US-based donors who donated $250USD or more for tax deduction purposes.
  3. Determine if/how to provide better cooling to our unfinished basement to prepare for summer. In the summer, our basement can get up to 90F without any servers or computer equipment. Obviously, that presents issues for continued hosting out of our basement.
  4. Documentation! Keep making more progress on updating our wiki with relevant documentation.

Upcoming HardenedBSD Infrastructure Changes

On Sunday, 27 Nov 2022, we will be temporarily taking down the HardenedBSD development and build infrastructure. We are working to find a new home for it and will be working those details out over the next few months.

We provide a read-only mirror of src and ports at GitHub:

src: https://github.com/HardenedBSD/hardenedBSD
ports: https://github.com/HardenedBSD/ports

Here are the short-term physical infrastructure changes:

1. GitLab will (hopefully) be brought back up within one week.
2. The Tor Onion Service endpoints will be brought back up at around the same time.
3. The nightly build server will be taken offline for an extended period of time until we find a new home for it.
4. The binary update server will be taken offline and brought back up at around the same time as the nightly build server.
5. The package building servers will be taken offline for an even more extended period of time. We encourage our community to learn how to use Poudriere to build their own packages.

Here are the short-term infrastructure policy changes:

1. Once the nightly build server is back online, we will no longer produce nightly builds. We will likely build twice per month on a bi-weekly schedule.
2. We will do the same for the binary update server. We will do our best to pair the hbsd-update builds with the bi-weekly builds to keep our users more in-sync with what is installed versus the latest update artifact.

If you know of a hosting provider within a two to four hour drive of Baltimore, Maryland, USA that would host our infrastructure for free with at least one public IPv4 address, please reach out. As a reminder, all donations--whether that's funding, equipment, services, or otherwise--are eligible for tax deductions in the US.

In full, our infrastructure takes around 24U, but we can get around with 16U. The physical infrastructure changes outlined above would be around 5U worth of equipment.

We appreciate the continued help and support from the community. HardenedBSD's continued success is enabled by the many generous ways in which the community contributes to the project.

Please reach out to me (shawn.webb@hardenedbsd.org and/or foundation@hardenedbsd.org) if you have any questions, comments, or concerns.

HardenedBSD October 2022 Status Report

It has been an exciting month for HardenedBSD. First up is an important announcement. I am officially looking for new job opportunities. This is important for the HardenedBSD project since the development and build infrastructure is housed at my (now former) employer's office.

I'm grateful for the two-and-a-half years in which BlackhawkNest has provided the project with free hosting. They have agreed to continue hosting the development/build infrastructure for free until the end of November. BlackhawkNest has been incredibly supportive of the project in many ways and I wish them well in their future endeavors.

HardenedBSD's development and build infrastructure will need to find a new home. Looking at the long term, I would eventually like HardenedBSD to stand independent of my employment. However, we currently lack the funding and will need to continue to rely on my employer until we gain enough sustained funding.

It is my hope that HardenedBSD's development and build infrastructure is transitioned in a timely manner to its new home, where ever that may be, before the end of November 2022. If you would like to help out in the effort to make HardenedBSD's infrastructure stand independent, please donate. We appreciate the community's contributions to the project, regardless of the form those contributions come in (code, advocacy, funding, etc.)

Please note that OS binary updates, package repos, and installer images are hosted elsewhere and will not be interrupted. GitLab and the build systems will be the only systems impacted.

Now, let's get into progress in the project itself!

In src:

  1. Shawn added a new sysctl tunable (hardening.pax.kmod_laod_disable) that, when set, disables loading all kernel modules from that point forward. The kld rc script has been updated such that users can specify hbsd_late_kld_prohibit in rc.conf, which will set the sysctl node after loading modules specified in kld_list. This work was sponsored by BlackhawkNest, Inc.
  2. Significant progress has been made on Cross-DSO CFI support. An installable version of HardenedBSD 14-CURRENT with Cross-DSO CFI enable can now build itself (meaning, `make buildworld buildkernel` works in a fully Cross-DSO CFI'd system.)
    • There's still more work to be done here. On a normal install of HardenedBSD 14-CURRENT, the following command fails when building the compiler toolchain:
      make buildworld WITHOUT_SYSTEM_COMPILER=yes WITHOUT_SYSTEM_LINKER=yes
    • The `ctfmerge` application segfaults when building the kernel. ctfmerge is needed for DTrace support. I plan to disable ctfmerge (thus disabling DTrace) in the Cross-DSO CFI feature branch and circle back around to fixing whatever bugs lie in ctfmerge. I'd rather keep the momentum around Cross-DSO CFI support going.

In ports:

  1. Shawn forked FreeBSD's Poudriere project to support the needs of building packages in HardenedBSD. By default, Poudriere creates a 1GB tmpfs mount for data. HardenedBSD has (slightly) outgrown that, so the size has increased to 2GB to account for future growth.
  2. Shawn disabled CFI for x11-servers/xorg-server
  3. Loic fixed x11-wm/enlightenment
  4. Loic fixed mail/bogofilter
  5. Loic fixed sysutils/pefs-kmod
  6. Loic fixed net-mgmt/netdisco-mibs
  7. Loic fixed x11-toolkits/gtkd
  8. Loic fixed x11-wm/piewm
  9. Loic removed lib32 in emulators/libc6-shim
  10. Shawn bumped the version for hardenedbsd/liblattutil

HardenedBSD September 2022 Status Report

I apologize for the delay in getting the September 2022 status report out. But alas, it has arrived!

My time was spent mostly on infrastructure. We're slowly aging out some incredibly old servers in our infrastructure, occasionally not by choice. The Dell R410 server that ran our auto-sync cron jobs decided to die. So I rebuilt the auto-sync jail on another Dell R410 server of the same age, but the PERC controller decided to die. So now, the auto-sync jail is hosted on another server--but this time on a performant, stable system.

In src and ports land, I spent most of my time just resolving the occasional merge conflict.

In src:

  1. Shawn ensured that the HardenedBSD copyright is always applied
  2. Loic did some house cleaning with a few files in src
  3. Loic removed leftover cruft from our LibreSSL-in-base experiment
  4. MrUnix0 changed the HardenedBSD pkg repo configuration in 14-CURRENT to use HTTPS rather than HTTP. We're still exploring whether this change can be safely MFC'd to 13-STABLE, but we're being very conservative here.
  5. FreeBSD updated `less(1)` to v608, which introduced a number of CFI violations. Shawn fixed two that were readily apparent.
  6. Loic set `-fstack-protector-strong` for the kernel.
  7. Loic fixed a few compiler warnings/errors when using a modified kernel config.

In ports:

  1. Shawn enabled PulseAudio support for net/freerdp. Having audio over RDP seems pretty useful.
  2. Loic enabled the sort plugin for editors/pluma.
  3. Loic added games/scratch
  4. Loic fixed the uname output in sysutils/mate-system-monitor
  5. Loic disabled Java support by default for editors/libreoffice
  6. Loic Fixed textproc/docbook2mdoc
  7. Shawn fixed the llvm compiler toolchain component tests, fixing CFI applicability detection
  8. Loic forced lld for graphics/cimg, science/cdo, and math/octave
  9. Loic disabled PaX MPROTECT for emulators/qemu70
  10. Loic fixed java/openjdk11
  11. MrUnix disabled PaX MPROTECT and PaX PAGEEXEC for games/assaultcube
  12. MrUnix disabled PaX MPROTECT and PaX PAGEEXEC for x11/lumina-core
  13. MrUnix disabled PaX MPROTECT and PaX PAGEEXEC for games/xonotic

I did a new build of hbsdfw in late September, but I didn't get around to deploying it at home as a good first test. I'm following some of the work the OPNsense folks are doing and it seems best to hold off on a new build until some things settle down in their core repo. I plan to kick off a new build once I'm confident the dust has settled.

Upcoming plans:

Many of those in the HardenedBSD community know that I've worked (incredibly slowly) off-and-on throughout the years on Cross-DSO CFI support in HardenedBSD. In October, I plan to resume that work starting mid-October. Here's where we stand on Cross-DSO CFI today:

I can compile (nearly) the entire dynamic world with Cross-DSO CFI. However, there is an interesting recursion issue at early application startup with some applications. The Cross-DSO CFI runtime intercepts calls to dlopen and dlclose. In certain cases, libc itself may call dlopen and/or dlclose. Some applications, even some in base (like `id(1)`) call libc functions that call into dlopen/dlclose. This presents problems with llvm's Cross-DSO CFI runtime.

libc is an incredibly attractive target given its large surface area. It's incredibly complex. At this time, I feel applying Cross-DSO CFI to libc itself may be too large of an undertaking, preventing tangible progress. Thus, my initial goal will be to apply CFI to as many shared libraries in base as I can, but likely not libc at this time. As Rome was not built in a single day, neither
will a Cross-DSO CFI HardenedBSD be. It is my hope that we will indeed apply CFI in the future to libc (in whole or in part), but that day is not today.

Building ports/packages will be another huge aspect of this. Back in 2018, the last time I made tangible progress on Cross-DSO CFI, the memory footprint ballooned when building packages due to CFI'd libraries in base. Eventually, the experimental package build failed due to memory pressure.

My main objective: end 2023 (yes: 2023) with Cross-DSO CFI enabled in HardenedBSD by default. Whether libc is a part of that is unknown, but we can hope.

To fit that main objective, I plan to take a back seat to most other development aspects of the project, with the exception of hbsdfw. I will definitely be involved in all other aspects of the project (the infrastructure, the Foundation, etc.) The only thing that is changing: I am formally delegating the implementation of new security and hardening techniques to the wider HardenedBSD community so that I can focus on Cross-DSO CFI.

I appreciate all the help the community has given the project to date. I'm especially grateful for the continued contributions, the advocacy, the support. This little project would not exist in its current state without the recurring love and support you, the community, provide. As I focus my attention on a more difficult and involved goal (that of Cross-DSO CFI), I'm hopeful for a renewed sense of excitement and support from the community.

HardenedBSD August 2022 Status Report

It's that time of the month for the HardenedBSD status report! My own status is pretty darn simple: Little time, no hacks. I hope to be back in the swing of things by the beginning of November. Life is keeping me busy. So I'm ever more grateful for the continued contributions by the HardenedBSD community.

However, Loic and MrUnix fixed a number of issues in both the source and ports repos.

In src:

  1. Loic fixed an issue MrUnix reported about a missing PaX ASLR macro when building a kernel with COMPAT_FREEBSD32 enabled.
  2. Loic updated bsdinstall with a few changes, updating which sysctl nodes to set.
  3. I pulled in a change from OpenBSD that randomizes how often the chacha20-based arc4random(3) reseeds itself.
  4. HardenedBSD user "apache2" enabled multi-console booting by default, enabling use of the serial console by default.

In ports:

  1. Loic disabled PIE for java/eclipse
  2. I disabled SafeStack for x11-servers/xorg-server
  3. Loic added a new port: hardenedbsd/kernel-nodebug
  4. Loic disabled PIE for sysutils/grub2-efi
  5. Loic disabled PIE for net-im/profanity
  6. Loic disabled PIE for astr/xephem
  7. Loic disabled PIE for lang/zig-devel
  8. Loic fixed sysutils/pefs-kmod
  9. Loic fixed textproc/sxml
  10. Loic disabled PIE for sysutils/fluent-bit
  11. Loic disabled PIE for mat/4ti2
  12. Loic disabled PIE for mat/mprime
  13. Loic disabled DTRACE for lang/erlang-runtime25
  14. Loic disabled the PDF option in comms/fl_moxgen
  15. Loic fixed mail/bogofilter
  16. Loic fixed lang/gcc13-devel
  17. Shawn disable variable auto-init for security/tor
  18. MrUNIX disabled the JIT for net-im/signal-desktop
  19. MrUNIX disabled MPROTECT and PAGEEXEC for games/veloren
  20. MrUNIX fixed the build of lang/mono5.10, lang/mono5.20, and lang/mono6.8

For hbsdfw:

hbsdfw, aka the HardenedBSD Firewall, has a new build for this month. As usual, the process for updating is:

  1. Backup your config
  2. Reinstall with the new build
  3. Restore your config

The default username and password have been changed:

Username: root
Password: hbsdfw

HardenedBSD July 2022 Status Report

This month was a crazy month for me (Shawn Webb). My wife and I adopted a new puppy, so life has been a bit on the exciting side. I'm hoping to get back into the swing of things in the next month or two.

With that said, let's get right into it.

In src:

  1. TPE and RTLD hardening were merged into 13-STABLE. I had posted a HEADS UP email on the users@ mailing list[0]. If you build your own ports/packages, please take note. RTLD hardening can cause issues when building ports/packages.

In ports:

  1. Loic fixed misc/rump
  2. Loic fixed sysutils/bareos18-server
  3. Loic disabled PaX MPROTECT and PAGEEXEC for lang/python39
  4. Loic fixed math/libpgmath
  5. Loic fixed building openjdk8 and openjdk11 for 14-CURRENT
  6. Loic fixed graphics/scrot
  7. Loic fixed devel/objecthash
  8. Loic fixed lang/perl5.36
  9. Loic fixed GCC 12 and 13-devel

  19. Ibrahim Kaikaa fixed lang/gcc11

For hbsdfw (the HardenedBSD 13-STABLE fork of OPNsense):

Today (30 Jul 2022), I published a new build[1]. It migrates us to PHP 8.0 and Python 3.9. It appears that the PHP 8.0 Radius extension (php80-pecl-radius) has issues, so I removed the package from the build. So if you're testing hbsdfw out and rely on Radius authentication, you'll want to skip this build.

I haven't had the time to fully bring up the infrastructure needed for in-place updates for hbsdfw, so the normal process of backing up the running config, reinstalling with the new build, and restoring the config is needed for this build and at least the following next few builds.

Please test the build out and let me know how it goes for you. Any message, whether it's "works fine for me" or "hey, we got a problem" helps me determine follow-up tasks for this fork.

The default username is "root" and the password is "dynfi". (The reason for the password being "dynfi" is because we use a forked version of the dynfi build scripts, which pull in the default dynfi opnsense config.)
