1.1 schwarze 25:
26: <ul>
1.78 deraadt 27: <li><a href="https://man.openbsd.org/ipsec.4">ipsec(4)</a>:
28: Started by John Ioannidis, Angelos D. Keromytis, Niels Provos, and
29: Niklas Hallqvist, imported February 20, 1997. OpenBSD was the first
30: free operating system to provide an IPSec stack.
31: <li><a href="https://man.openbsd.org/inet6.4">inet6(4)</a>:
32: First complete integration and adoption of IPv6 led by
33: "Itojun" (Dr. Junichiro Hagino) [WIDE/KAME], Craig Metz [NRL], and
34: Angelos D. Keromytis starting Jan 6, 1999.
35: Almost fully operational Jun 6, 1999 during the
36: <a href="hackathons.html">first OpenBSD hackathon</a>.
37: OpenBSD 2.7.
38: <li><strong>Privilege separation</strong>:
39: First implemented by
40: <a href="http://www.citi.umich.edu/u/provos/ssh/privsep.html">Niels Provos</a>
41: and Markus Friedl in OpenSSH in March 2002, released with OpenBSD 3.2.
42: The concept is now used in many OpenBSD programs, for example
43: <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>,
44: <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>,

72: etc.
73: <li><strong>Privilege revocation</strong>:
74: Related to the work on privilege separation, some programs were refactored
75: to drop privileges while holding onto a tricky resource such as a raw socket,
76: reserved port, or modification-locked bpf(4) descriptor,
77: for example
78: <a href="https://man.openbsd.org/ping.8">ping(8)</a>,
79: <a href="https://man.openbsd.org/traceroute.8">traceroute(8)</a>,
80: etc.
81: <li><strong>Stack protector</strong>:
82: Developed since 2001 as "propolice" by Hiroaki Etoh. Integrated, and
83: implemented for additional hardware platforms, by Miod Vallat and Theo
84: de Raadt. OpenBSD 3.3 was the first operating system to enable it
85: systemwide by default.
86: <li><strong>W^X</strong>:
87: First used for sparc, sparc64, alpha, and hppa in OpenBSD 3.3.
88: Strictly enforced by default since OpenBSD 6.0: a program can only
89: violate it if the executable is marked with <code>PT_OPENBSD_WXNEEDED</code>
90: and it is located on a filesystem mounted with the <code>wxallowed</code>
91: <a href="https://man.openbsd.org/mount.8">mount(8)</a> option.
92: <li><strong>GOT and PLT protection</strong> by ld.so:
93: first done as part of the W^X work in OpenBSD 3.3, by Dale Rahn and
94: Theo de Raadt. The GOT and PLT regions are read-only outside of ld.so
95: itself. Extended to the .init/.fini sections (constructors and
96: destructors) in OpenBSD 3.4.
97: <li><strong>ASLR</strong>:
98: OpenBSD 3.4 was the first widely used operating system to
99: provide it by default.
100: <li><a href="https://man.openbsd.org/gcc-local.1">gcc-local(1)</a>
101: __attribute__((__bounded__)) static analysis annotation
102: and checking mechanism:
103: Started by Anil Madhavapeddy on June 26, 2003
104: and ported to GCC 4 by Nicholas Marriott.
105: First released with OpenBSD 3.4.
106: <li><a href="https://man.openbsd.org/malloc.3">malloc(3)</a>
107: randomization implemented by Thierry Deval. Guard pages and randomized (delayed) free added by Ted Unangst.
108: Reimplemented by <a href="papers/eurobsdcon2009/otto-malloc.pdf">Otto Moerbeek</a>
109: for OpenBSD 4.4.
110: <li><strong>Position-independent executables (PIE)</strong>:
111: OpenBSD 5.3 was the first widely used operating system to enable it
112: globally by default, on seven hardware platforms.
113: Implemented in November 2008 by
114: <a href="https://www.openbsd.org/papers/nycbsdcon08-pie/">Kurt Miller</a>
115: and enabled by default by
116: <a href="https://www.openbsd.org/papers/asiabsdcon2015-pie-slides.pdf">Pascal Stumpf</a>
117: in August 2012.
118: <li><strong>Random-data memory</strong>:
119: the ability to specify that a variable should be initialized
1.68 deraadt 120: at load time with random byte values (placed into a new ELF
121: <b>.openbsd.randomdata</b> section) was implemented in
122: OpenBSD 5.3 by Matthew Dempsky.
1.78 deraadt 123: <li><strong>Stack protector per shared object</strong>:
124: using the random-data memory feature, each shared object was given its
125: own stack protector cookie in OpenBSD 5.3 by Matthew Dempsky.
126: <li><strong>Static-PIE</strong>:
127: Position-independent static binaries for /bin, /sbin and ramdisks.
128: Implemented for OpenBSD 5.7 by Kurt Miller and Mark Kettenis.
129: <li><strong>SROP</strong>
130: (<a href="https://man.openbsd.org/sigreturn.2">sigreturn(2)</a>
131: oriented programming) mitigation: attacks researched by
132: <a href="http://www.cs.vu.nl/~herbertb/papers/srop_sp14.pdf">Eric Bosman</a>
133: and Herbert Bos in 2014, solution implemented by Theo de Raadt in May 2016,
134: enabled by default since OpenBSD 6.0.
135: <li><strong>Library order randomization</strong>:
136: In <a href="https://man.openbsd.org/rc.8">rc(8)</a>, re-link
137: <code>libc.so</code>, <code>libcrypto</code>, and <code>ld.so</code>
138: on startup, placing the objects in a random order.
139: Theo de Raadt and Robert Peichaer, May 2016,
140: enabled by default since OpenBSD 6.0 and 6.2.
141: <li>Kernel-assisted lazy-binding for W^X safety in multi-threaded programs.
142: A new syscall <a href="https://man.openbsd.org/kbind.2">kbind(2)</a>
143: permits lazy-binding to be W^X safe in multi-threaded programs.
144: Implemented for OpenBSD 5.9 by Philip Guenther in July 2015.
145: <li>Process layouts in memory tightened to remove execute permission from
146: all segmented, non-instruction data and to remove write permission from
147: data that is only modified during loading and relocation.
148: By combining the RELRO (Read-Only after Relocation) design from the
149: GNU project with the original ASLR work from OpenBSD 3.3 and
150: strict lazy-binding work from OpenBSD 5.9, this is applied to not
151: just a subset of programs and libraries but rather to all programs
152: and libraries.
153: Implemented for OpenBSD 6.1 by Philip Guenther in August 2016.
154: <li>Use of <strong>fork+exec in privilege separated programs</strong>. The
155: strategy is to give each process a fresh & unique address space for
156: ASLR, stack protector -- as protection against address space discovery attacks.
157: Implemented first by
158: Damien Miller (<a href="https://man.openbsd.org/sshd.8">sshd(8)</a> 2004),
159: Claudio Jeker (<a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>, 2015),
160: Eric Faurot (<a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>, 2016),
161: Rafael Zalamena (various, 2016), and others.
162: <li><strong>trapsleds</strong>:
163: Reduction of incidental NOP instructions/sequences in the instruction
164: stream which could be useful potentially for ROP attack methods to
165: innaccurately target gadgets. These NOP sequences are converted into
166: trap sequences where possible. Todd Mortimer and Theo de Raadt, June
167: 2017.
168: <li><strong>Kernel relinking at boot</strong>:
169: the .o files of the kernel are relinked in random order from a
170: link-kit, before every reboot. This provides substantial interior
171: randomization in the kernel's text and data segments for layout and
172: relative branches/calls. Basically a unique address space for each
173: kernel boot, similar to the userland fork+exec model described above
174: but for the kernel. Theo de Raadt, June 2017.
1.61 deraadt 175: <li>
176: Rearranged i386/amd64 register allocator order in
177: <a href="https://man.openbsd.org/clang.1">clang(1)</a>
178: to reduce polymorphic RET instructions:
179: Todd Mortimer, November 20, 2017.
1.64 deraadt 180: <li>
1.72 mortimer 181: Reencoding of i386/amd64 instruction sequences to avoid
182: embedded polymorphic RET instructions. Enhancements to
183: <a href="https://man.openbsd.org/clang.1">clang(1)</a>
184: Todd Mortimer, April 28, 2018 and onwards.
1.78 deraadt 185: <li><b>MAP_STACK</b> addition to
1.64 deraadt 186: <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>
187: allows opportunistic verification that the stack-register
188: points at stack memory, therefore catching pivots to non-stack
189: memory (sometimes used in ROP attacks).
190: Theo de Raadt, April 12, 2018.
1.78 deraadt 191: <li><b>RETGUARD</b> is a replacement for the <b>stack-protector</b>
192: which uses a per-function random cookie (located in the read-only ELF
193: <b>.openbsd.randomdata</b> section) to consistency-check the
194: return address on the stack. Implemented for AMD64 and ARM64
195: by Todd Mortimer in OpenBSD 6.4.
196: <li><b>MAP_CONCEAL</b> addition to
1.76 otto 197: <a href="https://man.openbsd.org/mmap.2">mmap(2)</a>
198: disallows memory pages to be written to core dumps, preventing
199: accidental exposure of private information.
200: Theo de Raadt, Mark Kettenis and Scott Soule Cheloha,
201: February 2, 2019.
1.79 ! deraadt 202: <li>Similar to the opportunistic verification in <b>MAP_STACK</b>,
! 203: system-calls can no longer be performed from PROT_WRITE memory.
! 204: Theo de Raadt, June 2, 2019.
