The "-unix <path>" argument allows s_server and s_client to use a unix
domain socket in the filesystem instead of IPv4 ("-connect", "-port",
"-accept", etc). If s_server exits gracefully, such as when "-naccept"
is used and the requested number of SSL/TLS connections have occurred,
then the domain socket file is removed. On ctrl-C, it is likely that
the stale socket file will be left over, such that s_server would
normally fail to restart with the same arguments. For this reason,
s_server also supports an "-unlink" option, which will clean up any
stale socket file before starting.
If you have any reason to want encrypted IPC within an O/S instance,
this concept might come in handy. Otherwise it just demonstrates that
there is nothing about SSL/TLS that limits it to TCP/IP in any way.
(There might also be benchmarking and profiling use in this path, as
unix domain sockets are much lower overhead than connecting over local
IP addresses).

There are certainly many more constifiable strings in the various
interfaces, which I hope to get to eventually.

Add correct flags for DTLS 1.2, update s_server and s_client to handle
DTLS 1.2 methods.
Currently no support for version negotiation: i.e. if client/server selects
DTLS 1.2 it is that or nothing.
knock-on work than expected - they've been extracted into a patch
series that can be completed elsewhere, or in a different branch,
before merging back to HEAD.
1107. He says:
This is a followup to the NetWare patch that was applied to beta3. It
does the following:
- Fixes a problem in the CLib build with undefined symbols.
- Adds the ability to use BSD sockets as the default for the OpenSSL
socket BIO. NetWare supports 2 flavors of sockets and our Apache
developers need BSD sockets as a configurable option when building
OpenSSL. This adds that for them.
- Updates to the INSTALL.NW file to explain new options.
I have tried very hard to make sure all the changes are in NetWare
specific files or guarded carefully to make sure they only impact
NetWare builds. I have tested the Windows build to make sure it does
not break that since we have made changes to mk1mf.pl.
We are still working the gcc cross compile for NetWare issue and hope
to have a patch for that before beta 6 is released.
Use BUF_strlcat() instead of strcat().
Use BIO_snprintf() instead of sprintf().
In some cases, keep better track of buffer lengths.

Here's the description, submitted by Gisle Vanem <giva@bgnett.no>:
1. sock_init() renamed to ssl_sock_init() in ./apps/s_socket.c due
to name-clash with Watt-32.
2. rand() renamed to Rand() in ./crypto/bn/divtest.c due to name-clash
with <stdlib.h>
3. Added calls to dbug_init()/sock_init() in some demo programs.
4. Changed cflags/lflags in configure. Watt-32 install root now taken
from $WATT_ROOT.
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
This change includes all the name changes needed throughout all C files.
