[ Hopefully people on openssl-dev don't mind this discussion? It
seems slightly relevant. ]
I have made modification to e_os.h as follows,
#if defined(WINDOWS) && !defined(__CYGWIN32__)
[...]
#else
#ifdef VXWORKS
# include <ioLib.h>
# include <sockLib.h>
# include <hostLib.h>
# include <sysLib.h>
# undef m_len
# undef BUFSIZE
# undef DEVRANDOM
# define gethostbyname gethostname
#endif
#define get_last_socket_error() errno
#define clear_socket_error() errno=0
#define ioctlsocket(a,b,c) ioctl(a,b,c)
#define closesocket(s) close(s)
#define readsocket(s,b,n) read((s),(b),(n))
#define writesocket(s,b,n) write((s),(b),(n))
#endif
I don't know if they are really great or not. All the compiler flag,
-DNO_XXX, must be used with your OpenSSL application as well. Ie,
whatever it is that is using the OpenSSL library.
I had several problems with the BIO portion. I examined peices of it
and removed some functions that didn't seem to make sense for my box.
For instance, I don't trust DNS, I don't have DNS, and I don't like
DNS (well, ok, maybe I do, but it is another port to attack). So all
of the gethostbyname() calls were removed and we are using IP numbers
for all accesses.
My one patch to bss_bio.c is to add `#undef SSIZE_MAX' after the
e_os.h include. vxWorks has a habit of polluting the namespace. This
define in a vxWorks system header, but it means something completely
different.
If I am suppose to send this to some American government facility, I
will stop posting any more information.
hth,
Bill Pringlemeir.
