885448d74c Unbreak the old behavior of using UNKNOWN as a hostname if any of the 
addr->name->addr translations fail, because people might count on this
in "hosts deny" lines.

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.

If a reverse name lookup fails, show the name that we were trying to
look up.

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.

b8771f9615 Try to be better about handling the results of getaddrinfo(): when 
opening an inbound socket, we might get several address results,
e.g. for the machine's ipv4 and ipv6 name.

If binding a wildcard, then any one of them should do.  If an address
was specified but it's insufficiently specific then that's not our
fault.

However, some of the advertized addresses may not work because e.g. we
don't have IPv6 support in the kernel.  In that case go on and try all
addresses until one succeeds.

d5d4b28220 Put the new address family option into an options struct. We have too 
many globals already.

Better error messages for network-related failures.

1f0fa9318a Remove highly suspicious redefinition of sockaddr structure -- there 
seems no point using anything but the platform's native definition,
and if we can't get that from the system headers we're hosed anyhow.

06963d0fca Merge KAME.net IPv6 patch: you can now (in theory) pass IPv6 hostnames 
or literal IP addresses to rsync, and if your platform supports them
they will be used.  Also there are -4 and -6 command-line options to
choose the default address type.  Thankyou!

eecd22ff7b Merge in the LIBSMB_PROG idea from samba, so that you can do 
RSYNC_CONNECT_PROG='./rsync --daemon' ./rsync -vvvvvv  localhost::

to test as a daemon without actually having to listen on a port.

7d91d5a619 Check that gethostbyname does actually return AF_INET addresses, since 
that's all we can handle.

Also, try a new method of handling in_addr and hostent that will
hopefully work on Cray machines without 32-bit types.

ac2a1a449d Use socklen_t if defined, or otherwise int. This tries to fix

int.

4d66e00afa If binding to a low-numbered port fails with EACCES, then the error 
message should explain that you probably need to be root.

(Why leave off the final S?  Kernighan must have been a *really* slow
typist.)

45a8354004 When running as --daemon in the background and using a "log file" rsyncd.conf 
directive, close the log file every time it is open when going to sleep on
the socket.  This allows the log file to get cleaned out by another process.

d41c7d025c Use MAXHOSTNAMELEN (256) for the array holding the host_name in socket.c 
instead of 200.  Move the defines of True and False to rsync.h.  Eliminate
the defines of BOOL in loadparm.c and params.c because it is already
defined in rsync.h.  Changes suggested by Roman Gollent roman.gollent@wdr.com

11a5a3c704 and I thought I wasn't going to do any rsync coding for a while ...
