1.59 job 29: <li>
30: <a href="https://man.openbsd.org/ipsec.4">ipsec(4)</a>:
31: Started by John Ioannidis, Angelos D. Keromytis, Niels Provos, and
32: Niklas Hallqvist, imported February 20, 1997. OpenBSD was the first
33: free operating system to provide an IPSec stack.
34: </li>
35: <li>
36: <a href="https://man.openbsd.org/inet6.4">inet6(4)</a>:
37: First complete integration and adoption of IPv6 led by
38: "Itojun" (Dr. Junichiro Hagino) [WIDE/KAME], Craig Metz [NRL], and
39: Angelos D. Keromytis starting Jan 6, 1999.
40: Almost fully operational Jun 6, 1999 during the
41: <a href="hackathons.html">first OpenBSD hackathon</a>.
42: OpenBSD 2.7.
43: </li>
44: <li>
45: <strong>Privilege separation</strong>:
46: First implemented by
47: <a href="http://www.citi.umich.edu/u/provos/ssh/privsep.html">Niels Provos</a>
48: and Markus Friedl in OpenSSH in March 2002, released with OpenBSD 3.2.

79: etc.
80: </li>
81: <li>
82: <strong>Privilege revocation</strong>:
83: Related to the work on privilege separation, some programs were refactored
84: to drop privileges while holding onto a tricky resource such as a raw socket,
85: reserved port, or modification-locked bpf(4) descriptor,
86: for example
87: <a href="https://man.openbsd.org/ping.8">ping(8)</a>,
88: <a href="https://man.openbsd.org/traceroute.8">traceroute(8)</a>,
89: etc.
90: </li>
91: <li>
92: <strong>Stack protector</strong>:
93: Developed since 2001 as "propolice" by Hiroaki Etoh. Integrated, and
94: implemented for additional hardware platforms, by Miod Vallat and Theo
95: de Raadt. OpenBSD 3.3 was the first operating system to enable it
96: systemwide by default.
97: </li>
98: <li>
99: <strong>W^X</strong>:
100: First used for sparc, sparc64, alpha, and hppa in OpenBSD 3.3.
101: Strictly enforced by default since OpenBSD 6.0: a program can only
102: violate it if the executable is marked with <code>PT_OPENBSD_WXNEEDED</code>
103: and it is located on a filesystem mounted with the <code>wxallowed</code>
104: <a href="https://man.openbsd.org/mount.8">mount(8)</a> option.
105: </li>
106: <li>
107: <strong>GOT and PLT protection</strong> by ld.so:
108: first done as part of the W^X work in OpenBSD 3.3, by Dale Rahn and
109: Theo de Raadt. The GOT and PLT regions are read-only outside of ld.so
110: itself. Extended to the .init/.fini sections (constructors and
111: destructors) in OpenBSD 3.4.
112: </li>
113: <li>
114: <strong>ASLR</strong>:
115: OpenBSD 3.4 was the first widely used operating system to
116: provide it by default.
117: </li>
118: <li>
119: <a href="https://man.openbsd.org/gcc-local.1">gcc-local(1)</a>
120: __attribute__((__bounded__)) static analysis annotation
121: and checking mechanism:
122: Started by Anil Madhavapeddy on June 26, 2003
123: and ported to GCC 4 by Nicholas Marriott.
124: First released with OpenBSD 3.4.
125: </li>
126: <li>
127: <a href="https://man.openbsd.org/malloc.3">malloc(3)</a>
128: randomization implemented by Thierry Deval. Guard pages and randomized (delayed) free added by Ted Unangst.
129: Reimplemented by <a href="papers/eurobsdcon2009/otto-malloc.pdf">Otto Moerbeek</a>
130: for OpenBSD 4.4.
131: </li>
132: <li>
1.65 kurt 133: <strong>Position-independent executables (PIE)</strong>:
1.59 job 134: OpenBSD 5.3 was the first widely used operating system to enable it
135: globally by default, on seven hardware platforms.
1.65 kurt 136: Implemented in November 2008 by
137: <a href="https://www.openbsd.org/papers/nycbsdcon08-pie/">Kurt Miller</a>
138: and enabled by default by
139: <a href="https://www.openbsd.org/papers/asiabsdcon2015-pie-slides.pdf">Pascal Stumpf</a>
140: in August 2012.
1.59 job 141: </li>
142: <li>
143: <strong>Random-data memory</strong>:
1.68 deraadt 144: the ability to specify that a variable should be initialized
145: at load time with random byte values (placed into a new ELF
146: <b>.openbsd.randomdata</b> section) was implemented in
147: OpenBSD 5.3 by Matthew Dempsky.
1.59 job 148: </li>
149: <li>
150: <strong>Stack protector per shared object</strong>:
151: using the random-data memory feature, each shared object was given its
152: own stack protector cookie in OpenBSD 5.3 by Matthew Dempsky.
153: </li>
154: <li>
155: <strong>Static-PIE</strong>:
156: Position-independent static binaries for /bin, /sbin and ramdisks.
1.65 kurt 157: Implemented for OpenBSD 5.7 by Kurt Miller and Mark Kettenis.
1.59 job 158: </li>
159: <li>
160: <strong>SROP</strong>
161: (<a href="https://man.openbsd.org/sigreturn.2">sigreturn(2)</a>
1.71 deraadt 162: oriented programming) mitigation: attacks researched by
1.59 job 163: <a href="http://www.cs.vu.nl/~herbertb/papers/srop_sp14.pdf">Eric Bosman</a>
1.71 deraadt 164: and Herbert Bos in 2014, solution implemented by Theo de Raadt in May 2016,
1.59 job 165: enabled by default since OpenBSD 6.0.
166: </li>
167: <li>
168: <strong>Library order randomization</strong>:
169: In <a href="https://man.openbsd.org/rc.8">rc(8)</a>, re-link
170: <code>libc.so</code>, <code>libcrypto</code>, and <code>ld.so</code>
171: on startup, placing the objects in a random order.
172: Theo de Raadt and Robert Peichaer, May 2016,
173: enabled by default since OpenBSD 6.0 and 6.2.
174: </li>
175: <li>
176: Kernel-assisted lazy-binding for W^X safety in multi-threaded programs.
177: A new syscall <a href="https://man.openbsd.org/kbind.2">kbind(2)</a>
178: permits lazy-binding to be W^X safe in multi-threaded programs.
179: Implemented for OpenBSD 5.9 by Philip Guenther in July 2015.
180: </li>
181: <li>
182: Process layouts in memory tightened to remove execute permission from
183: all segmented, non-instruction data and to remove write permission from
184: data that is only modified during loading and relocation.
185: By combining the RELRO (Read-Only after Relocation) design from the
186: GNU project with the original ASLR work from OpenBSD 3.3 and
187: strict lazy-binding work from OpenBSD 5.9, this is applied to not
188: just a subset of programs and libraries but rather to all programs
189: and libraries.
190: Implemented for OpenBSD 6.1 by Philip Guenther in August 2016.
191: </li>
192: <li>
193: Use of <strong>fork+exec in privilege separated programs</strong>. The
194: strategy is to give each process a fresh & unique address space for
195: ASLR, stack protector -- as protection against address space discovery attacks.
196: Implemented first by
197: Damien Miller (<a href="https://man.openbsd.org/sshd.8">sshd(8)</a> 2004),
198: Claudio Jeker (<a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, 2015),
199: Eric Faurot (<a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>, 2016),
200: Rafael Zalamena (various, 2016), and others.
201: </li>
202: <li>
203: <strong>trapsleds</strong>:
204: Reduction of incidental NOP instructions/sequences in the instruction
205: stream which could be useful potentially for ROP attack methods to
206: innaccurately target gadgets. These NOP sequences are converted into
207: trap sequences where possible. Todd Mortimer and Theo de Raadt, June
208: 2017.
209: </li>
210: <li>
211: <strong>Kernel relinking at boot</strong>:
212: the .o files of the kernel are relinked in random order from a
213: link-kit, before every reboot. This provides substantial interior
214: randomization in the kernel's text and data segments for layout and
215: relative branches/calls. Basically a unique address space for each
216: kernel boot, similar to the userland fork+exec model described above
217: but for the kernel. Theo de Raadt, June 2017.
218: </li>
1.61 deraadt 219: <li>
220: Rearranged i386/amd64 register allocator order in
221: <a href="https://man.openbsd.org/clang.1">clang(1)</a>
222: to reduce polymorphic RET instructions:
223: Todd Mortimer, November 20, 2017.

! 229: Todd Mortimer, April 28, 2018 and onwards.

1.66 schwarze 232: <b>MAP_STACK</b> addition to
1.64 deraadt 233: <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>
234: allows opportunistic verification that the stack-register
235: points at stack memory, therefore catching pivots to non-stack
236: memory (sometimes used in ROP attacks).
237: Theo de Raadt, April 12, 2018.
238: </li>
1.68 deraadt 239: <li>
240: <b>RETGUARD</b> is a replacement for the <b>stack-protector</b>
1.70 deraadt 241: which uses a per-function random cookie (located in the read-only ELF
242: <b>.openbsd.randomdata</b> section) to consistency-check the
1.68 deraadt 243: return address on the stack. Implemented for AMD64 and ARM64
244: by Todd Mortimer in OpenBSD 6.4.
