b0fd253afc Applied a slightly-tweaked version of Oliver Braun's patch that 
implements listening on multiple addresses and a fix for IPv6-only
systems.

9f639210ca Prevent the "Connection reset by peer" messages often seen from Cygwin. 
Result of a lot of discussion over the last year and a half.  Based on
a patch from Randy O'Meara, cleaned up a bit by Max Bowsher.

39993af514 The function passed to start_accept_loop() now takes 2 fd ints (for 
the daemon via remote-shell support).

32f761755e Try to fix ctype issues by always calling these functions as 
if (!isdigit(* (unsigned char *) p)) {

so that the argument is always in the range of unsigned char when
coerced to an int.

(See digit 1.)

a7dc44d27d Doc. 
Correction from Nelson Beebe: argument to functions such as isspace()
must be an int, not a char.  This could cause sign-extension problems.

145794936f Patch from Jos Backus <josb@cncdsl.com> to use HAVE_SOCKADDR_LEN rather 
than HAVE_SOCK_SIN_LEN around use of sin_len.  Correct usage was already
in place in clientname.c.

bbc09ffba9 When doing a name->addr translation to check for spoofing, give the 
resolver the address family of the original address as a hint, so that
we're more likely to find the correct A or AAAA record.,

9a5a86734f Refactor client_name() into smaller functions. 
Better messages for DNS failure.

If we can get a reverse name for an IP address, but not confirm that
it is correct using a forward lookup then we still proceed to use the
name, but also emit a warning.

13e29995f5 Get rid of global_opts struct as suggested by Dave -- too many 
problems with initialization.

Change the algorithm from trying to open an inbound socket with
getaddrinfo: keep trying suggested addresses until we find one on
which we can both get a socket and bind.  Not convinced this is the
best, but it's probably better.

cb1bcc7ebb open_socket_in was attempting to try all the protocols returned from 
getaddrinfo(), but only if a corresponding call to socket() returned one of
three *NOSUPPORT errno codes.  A Redhat 6.2 system was observed returning
EINVAL instead so it never went on to try IPv4.  This update adds EINVAL to
the list.  Question: why not always continue through the list regardless of
what errno is?

51f289d1e6 Some platforms don't have sa_family_t. 2001-12-05 13:44:37 +00:00
Martin Pool
d91c8c50d2 RFC2553 just says that sockaddr_storage has to have initial fields 
isomorphic to sa_family etc from a struct sockaddr, not what they're
called.  On some platforms they seem not to be called ss_family.
Rather than guess, we will try casting to a sockaddr and looking
through that -- I think this is what the RFC intends.

e20a4f84d6 Some platforms may have getaddrinfo() but not sockaddr_storage. 2001-12-05 13:19:16 +00:00
Martin Pool
2d6dbe290c Change back to using sockaddr_storage rather than sockaddr_in. If 
sockaddr_storage is not defined, then supply our own definition that
will hopefully satisfy RFC2553 but also compile on all supported
platforms.
