2 @brief Externally maintained code
4 The "ext" directory holds code that was written elsewhere, and is not
5 reliably packaged as a library where we want to build, so we ship
8 In general, you should not edit this code: we are not the maintainers.
9 Instead, you should submit patches upstream.
11 OpenBSD_malloc_Linux.c:
13 > The OpenBSD malloc implementation, ported to Linux. Used only when
14 > --enable-openbsd-malloc is passed to the configure script.
19 > Implementations of strlcat and strlcpy, the more sane replacements
20 > for strcat and strcpy. These are nonstandard, and some libc
21 > implementations refuse to add them for religious reasons.
25 > An implementation of a hash table in the style of Niels Provos's
26 > tree.h. Shared with Libevent.
32 > A unit testing framework. https://github.com/nmathewson/tinytest
36 > A copy of sys/queue.h from OpenBSD. We keep our own copy rather
37 > than using sys/queue.h, since some platforms don't have a
38 > sys/queue.h, and the ones that do have diverged in incompatible
39 > ways. (CIRCLEQ or no CIRCLEQ? SIMPLQ or STAILQ?) We also rename
40 > the identifiers with a TOR_ prefix to avoid conflicts with
45 > A copy of Adam Langley's curve25519-donna mostly-portable
46 > implementations of curve25519.
51 > Marek Majkowski's implementation of siphash 2-4, a secure keyed
52 > hash algorithm to avoid collision-based DoS attacks against hash
57 > Headers and runtime code for Trunnel, a system for generating
58 > code to encode and decode binary formats.
62 > Daniel Bernsten's portable ref10 implementation of ed25519.
67 > Andrew Moon's semi-portable ed25519-donna implementation of
68 > ed25519. Public domain.
72 > David Leon Gil's portable Keccak implementation. CC0.
76 > Portable readpassphrase implementation from OpenSSH portable, version
81 > William Ahern's hierarchical timer-wheel implementation. MIT license.
85 > Contains an overflow-checking 64-bit signed integer multiply
86 > from LLVM's compiler_rt. For some reason, this is missing from
87 > 32-bit libclang in many places. Dual licensed MIT-license and
88 > BSD-like license; see mulodi/LICENSE.TXT.
