			<content:encoded>Hey I notice the forums are a little dead but ill try anyway. This is going to be my first time attending defcon and im still a begginer. I am currently transitioning from accounting work to security. Ive started with my Google cs cert and am doing try hack me now and will go for my comptia + after. My questions are first any suggestions on what villages I should focus on as someone in my position and begginer skill level .  Im aiming to get Soc level 1 job to start when I can get my foot in the door. Second is there potential for job networking ? Also I noticed there are classes the week after is that just a more in depth teaching conference or ? Any advice I would appreciate it as a first timer . Any recommendations of things I should bring with me . </content:encoded>

			<content:encoded><![CDATA[Sorry for the ignorance.  Some newbie questions that I'm not seeing outright.  First year attending DEFCON.  Bringing my 16yo w/ me because I think it'll be great.<br />
<br />
Not staying at a hotel nearby, but instead about 10 minutes away.  Hotel prices are considerably cheaper.  How bad is parking at the convention center?  Will it be an issue finding a place to park?  If I need to park way out in the boondocks, I'll live.  I just have no idea on LVCC parking conditions.<br />
<br />
I'm buying my tickets ahead of time online.  Will I need to worry about badge availability?  Will I need to worry about linecon if I already have my ticket/badge?]]></content:encoded>

			<link>https://forum.defcon.org/node/255479</link>
			<pubDate>Wed, 04 Mar 2026 21:39:21 GMT</pubDate>

			<content:encoded><![CDATA[February saw a few changes in HardenedBSD. The majority of my time was spent chasing down the kernel crash in HardenedBSD 15-STABLE that has been plaguing our users. I worked on narrowing down to a three-day window during which a commit was made that causes the crash.<br />
<br />
As I write this, I'm narrowing that down further to the specific commit. I'm hoping to have this resolved this month. If I find and fix the problem this week, I will create new builds for folks to use. Otherwise, the next scheduled regular quarterly build is for 01 Apr 2026.<br />
<br />
I appreciate everyone's patience on this. This has been a tricky bug (at times, it fit the description of a &quot;heisenbug&quot;). My spare time is limited (I have a rather large amount of tasks/obligations in everyday ${LIFE} right now), so it has naturally taken a long while to get to this point.<br />
<br />
While inbetween clients at my dayjob, I have been granted the opportunity to research meshtastic and other mesh networking projects. I'm getting a lot closer in my censorship- and surveillance-resistant mesh network proof-of-concept. I'm now at the point where I need to port Linux-specific code to HardenedBSD. I'm hoping to get normal tcp/ip packets flowing through Reticulum nodes on the inside of six months. This project, <a href="https://hardenedbsd.org/article/shawn-webb/2024-09-23/hardenedbsd-and-protectli-collaborates-censorship-and-surveillance" target="_blank" rel="nofollow">announced</a> in partnership with Protectli one-and-a-half years ago[1], is starting to move along at a nice pace. I will have more to share on that by the next status report.<br />
<br />
On Saturday, 28 Feb 2026, I had given my local Hackers N' Hops chapter a little show &amp; tell of Meshtastic, Reticulum, and HardenedBSD. I met with a bunch of really cool hacckers there, and demoed two Reticulum RNodes backed by Reticulum instances on two HardenedBSD laptops. I demoed an exec-over-meshtastic Python script I wrote the day prior. The script is available on Radicle as rad:z44pvAJS7SiQf2CGtpn8hY44GDMyu.<br />
<br />
Speaking of Radicle, I plan to migrate some of my personal repos away from our self-hosted GitLab and onto the Radicle network. With time, I'm hoping to migrate us completely towards Radicle. Now would be a good time for those who want to contribute to HardenedBSD to start playing around and experimenting with Radicle.<br />
<br />
<b>In src:</b><ol class="decimal"><li>Contributor &quot;gmg&quot; hardened the kernel crashdump interface.</li>
<li>Opt zlib kernel module into -ftrivial-var-auto-init=zero.</li>
<li>bsdinstall(8): Align us more closely with FreeBSD.</li>
</ol><b>In ports:</b><ol class="decimal"><li>net-p2p/reticulum was updated to 1.1.3_2</li>
<li>Disable PaX PAGEEXEC and PaX NOEXEC for science/zotero</li>
<li>Bring in candidate patch to fix dns/unbound</li>
<li>Hook hardenedbsd/ctrl into the build</li>
<li>0x1eef added a new port: hardenedbsd/ctrl</li>
<li>Bump ports-mgmt/pkg to 3.5.1_1</li>
<li>0x1eef updated a port: portzap v2.1.1</li>
<li>0x1eef updated a port: sourcezap v2.1.1</li>
</ol><br />
Once I have figured out what's going on with the 15-STABLE panic and have a proper fix in place, I plan to quickly switch gears towards hbsdfw. I haven't produced a working hbsdfw build in a long time, and it's far past due. After that, I plan to switch right back to the Reticulum research and development.<br />
<br />
I'll make sure to keep the community informed of the 15-STABLE findings and fixes.<br />

			<content:encoded><![CDATA[January was a busy month with regards to infrastructure. With both OpenSSL and FreeBSD announcing security fixes, we published new builds just weeks after our new quarterlies dropped. :-)<br />
<br />
Now that we have the new quarterlies, I plan to &quot;MFC&quot; (old FreeBSD CVS/SVN term for &quot;Merge From Current&quot;.) Kids these days call it `git cherry-pick`. MFC is shorter to type, so that's what I'll use. I plan to MFC a number of commits made in hardened/current/master to the hardened/15-stable/main branch this week.<br />
<br />
I've also received multiple reports of crashes with the 15-STABLE installer. I haven't been able to work on this just yet, but am hoping to in the next two weeks. It is almost my current first priority (the MFCs being first.) I figure that if testing the cherry-picked code proves successful, I could cherry-pick those commits into the relevant quarterly branch. Kind of a &quot;thank you&quot; gesture for being patient with me. :-)<br />
<br />
I applied relevant updates across the entire infrastructure. I migrated the package repos from being served by a leased server with limited storage to out of my home with plenty of storage. My next goal is to fully automate the build, including syncing. This will mark a good next step to eventually supporting mirroring our package repos. It's much easier to transfer a 140GB package repo over a local 2.5Gbps LAN than a 150Mbps link upstream.<br />
<br />
I spent some time experimenting with Meshtastic and Reticulum. I'm getting a better picture from a user's perspective on the current state of mesh networking. My next goal is to teach Reticulum's BackboneInterface implementation how to work on FreeBSD/HardenedBSD.<br />
<br />
Two of the four donated Protectli devices are providing the testing lab for this Meshtastic and Reticulum research. Even though the timeframe has shifted pretty dramatically, I'm grateful for their donations and their support.<br />
<br />
<b>In src:</b><ol class="decimal"><li>Opt ipfw into -ftrivial-var-auto-init=zero</li>
<li>Remove our old MAC hook for jail/prison destruction (this commit breaks building secadm. I'm waiting on upstream to implement a specific MAC hook, and a patch for (for src, not for secadm) is being worked on by FreeBSD's Kyle Evans.)</li>
<li>Disable WITNESS' checking of vnode locks by default. FreeBSD changed some vnode locking semantics and not all filesystem code paths have been updated. As such, we are seeing vnode locking-related panics. I need to get a consequtive block of time to dive in. I'm not a filesytems developer, so this one might take a while to figure out unless someone beats me to it.</li>
<li>rc.subr: Ignore required_modules failures in jails (patch submission by leper4{ _AT_ }protnmail.com.)</li>
</ol><b>In ports:</b><ol class="decimal"><li>Bump ftp/curl to 8.18.0</li>
<li>Update Reticulum to latest git HEAD</li>
<li>Disable HARDCFLAGS for devel/avr-gcc</li>
<li>Enable ZEROREG for security/openssl3*. This could induce a noticeable performance hit. Please let me know if you have any serious performance issues after this next package build.</li>

			<content:encoded><![CDATA[This status report is going to be a lengthy one. Due to scheduling conflicts, I was unable to get out the November status report, this one will cover the two months November - December 2025.<br />
<br />
A large portion of my focus has been on the infrastructure, getting a build environment for the recently-created hardened/15-stable/main branch. As discussed in a previous mailing list thread[1], the 14-STABLE build infrastructure has now been migrated to 15-STABLE. We have archived the last 14-STABLE package build, which last completed on 24 Dec 2025.<br />
<br />
We self-host nearly the entirety of our infrastructure out of my home. We have only one leased server, from the fine folks at NetActuate (previously RootBSD). This leased server hosts our main website, the hbsd-update build artifacts, and the package repos. Our package repos, naturally, grow over time. Back when we started this, each package repo was at most 75GB in size. Now we're encroaching 135GB.<br />
<br />
We now have a 30TB NAS in the home-based infrastructure. In order to support the growth, we will be migrating the package repo to the home infra. The package repos themselves have already been migrated. The only thing left to do is adjust the various DNS entries. I plan to do that once we have a usable 15-STABLE package repo. We will update this[2] mailing list thread when the migration has completed, DNS records and all. There will likely be a little blip in HTTPS/TLS connections as we regenerate LetsEncrypt certs. There's a delicate dance here. I plan to keep everyone informed as to when I begin and complete the process.<br />
<br />
The 14-STABLE build server (which is now being migrated to 15-STABLE) housed two VMs:<ol class="decimal"><li>The OS installer/update build VM. This builds the artifacts published at <a href="https://installers.hardenedbsd.org/" target="_blank" rel="nofollow">https://installers.hardenedbsd.org/</a> and mirrors.</li>
<li>The package build VM.</li>
</ol>When we deployed that (stupendously) slow server to test its capabilities as a build server for 15-STABLE, we followed the same pattern: two separate VMs. We are going to keep the 15-STABLE OS installer/update build VM on that slow server. We're going to power off the 14-STABLE OS build VM and increase the resources to the package build VM. This means we should be able to decrease the time it takes for that server to produce a usable package repo. Naturally, this comes at a cost of a slow build time for the OS installer/updates, but that process can tolerate **a lot** of slowness. So long as it can produce its build artifacts in less than 48 hours, I'm satisfied. It's the package building (36,000+ packages) that takes the most resources.<br />
<br />
I spent a lot of time in the ports tree over the past couple months. The focus was on fixing ports broken by the various hardening techniques we employ. The introduction of -Werror=format-security caused a large amount of fallout, which I have been addressing. While addressing those, I figured I might as well fix ports broken by the other techniques.<br />
<br />
I'm working on enhancing libhbsdcontrol with better error handling. I'm hoping to have that work committed in early January 2026.<br />
<br />
I'm hoping in January to spend some time on hbsdfw. The VM I've been using to build hbsdfw has been panicking when the Poudriere build finishes when building the hbsdfw packages. In Q1 2026, I plan to migrate hbsdfw from HardenedBSD 14-STABLE to 16-CURRENT. Following the hardened/current/master src branch will lighten my load in maintaining this little hobby subproject.<br />
<br />
I need to file a bug report upstream in FreeBSD/OpenZFS to track this kernel panic. The panic happens when something during the build checks whether PaX PAGEEXEC is enabled through looking up a filesystem extended attribute. OpenZFS recently changed how filesystem extended attributes work, so it's possible we're hitting a unique edge case.<br />
<br />
In January, I'm going to get two lab environments set up:<ol class="decimal"><li>Internal Reticulum nodes to test the Reticulum protocol and its potential for use with our censorship- and surveillance-resistant mesh network R&amp;D.</li>
<li>Internal Radicle nodes to start concerted testing to eventually replace GitLab with Radicle.</li>
</ol>I feel somewhat down for not making more progress this year on the censorship- and surveillance-resistant networks. I'm hoping to place more emphasis on this in 2026.<br />
<br />
<b>In src:</b><ol class="decimal"><li>Always build elftc-nm and elft-ar</li>
<li>TPE: Ensure user-owned vnodes are unwritable</li>
<li>ASLR: Use VMFS_NO_SPACE to map the stack</li>
<li>Add various C/C++ hardening flags:<ol class="decimal"><li>-fno-delete-null-pointer-checks</li>
<li>-Werror=format-security</li>
</ol></li>
<li>Unlock the sound mutex on error</li>
<li>Fix branch detection in release</li>
