2013-11-09[BB#81] allow listening on multiple families when no Listen is provided in ↵Michael Adam1-2/+9
config This is achieved by not stopping at the first result of getaddrinfo that we managed to listen on: Without "Listen" in the config, we call getraddrinfo with NULL address. With AI_PASSIVE, this gives results for both IPv4 and IPv6 wildcard addresses (if both are supported). This lets tinyproxy listen on both IPv4 and IPv6 wildcard if the system supports them.

2013-11-09sock: set IPV6_V6ONLY on the socket before binding an IPv6 addressMichael Adam1-0/+12
so that we can bind wildcard for both IPv4 and IPv6. Signed-off-by: Michael Adam <obnox@samba.org>
2013-11-09sock: factor listening on one socket out of the gai-result-loop in listen_sock()Michael Adam1-48/+62

2013-11-09sock: move listen() into the getaddrinfo result loop in listen_sock()Michael Adam1-22/+22
This also reverses the exit logic of the loop. It prepares listening on multiple addresses. Signed-off-by: Michael Adam <obnox@samba.org>
2013-11-09child: use a list of listen_fds instead of one single listenfd.Michael Adam1-2/+5
This prepares listenting on multiple sockets, which will be ussed to fix listening on the wildcard (listen on both ipv6 and ipv4) and help add the support for multiple Listen statements in the config Signed-off-by: Michael Adam <obnox@samba.org>
2013-11-09sock: add addr argument to listen_sock()Michael Adam1-2/+2
instead of using config.ipAddr internally. This is in preparation to make it possible to call it for multiple addresses. Signed-off-by: Michael Adam <obnox@samba.org>
2013-11-09sock/child: remove global variable addrlen.Michael Adam1-8/+3
This changes listen_sock() to not return the addrlen of the used address from getaddrinfo call to the caller, stored in global addrlen in child.c. This was only used to be able to allocate enough space for the arguments to the later accept call depending on whether IPv4 or IPv6 is used. This removes the need to pass this info by always allocating sizeof(struct sockaddr_storage) instead, which is enough to carry both sockaddr_in and sockaddr_in6.

2010-03-09Revert "Revert "Pass address family when binding to outgoing socket""Mukund Sivaraman1-4/+7
This reverts commit 70885bf029a6f857684f99618f867b5c47767ae0. It looks like bug #69 needs this fix after all.

2010-01-21Revert "Pass address family when binding to outgoing socket"Mukund Sivaraman1-7/+4
This reverts commit 65ef313cc4601b5ad84d1da1800ff38bf8f046a9. This patch could've been the reason for BB#69.

bind Somehow this got moved too far down in the ipv6 changes. Thanks to Mathew Mrosko for helping me debugging this. Michael

2009-09-15Indent code to Tinyproxy coding styleMukund Sivaraman1-170/+150
The modified files were indented with GNU indent using the following command: indent -npro -kr -i8 -ts8 -sob -l80 -ss -cs -cp1 -bs -nlps -nprs -pcs \ -saf -sai -saw -sc -cdw -ce -nut -il0 No other changes of any sort were made.

2008-12-08Convert tabs to spacesMukund Sivaraman1-25/+25
2008-12-01Reformat code to GNU coding styleMukund Sivaraman1-153/+167
This is a commit which simply ran all C source code files through GNU indent. No other modifications were made.
2008-05-24Updated copyright, license notices in source codeMukund Sivaraman1-16/+20
The notices have been changed to a more GNU look. Documentation comments have been separated from the copyright header. I've tried to keep all copyright notices intact. Some author contact details have been updated.

2005-08-15* [Indent] Ran Source Through indentRobert James Kaes1-150/+152
I re-indented the source code using indent with the following options: indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs There are now _no_ tabs in the source files, and all indentation is eight spaces. Lines are 80 characters long, and the procedure type is on it's own line. Read the indent manual for more information about what each option means.
2005-07-12* Specified Correct typedef in getsock_ip()Robert James Kaes1-2/+2
Changed the variable type for the namelen variable to the correct socklen_t type. The configure script already checked for it, but for some reason I never got around to actually using it in this function.
2004-04-27Added the "BindSame" configure directive from Oswald Buddenhagen.Robert James Kaes1-10/+38
This allows tinyproxy to respond to a request bound to the same interface that the request came in on. As Oswald explains: "attached is a patch that adds the BindSame option. it causes binding an outgoing connection to the ip address of the respective incoming connection. that way one can simulate an entire proxy farm with a single instance of tinyproxy on a multi-homed machine." Cool.
2004-02-18Converted the various socket functions to work with both IPv4 and IPv6Robert James Kaes1-86/+84
addresses.
2002-10-03#Style formatting change.Robert James Kaes1-2/+2
2002-05-31(getpeer_information): Fixed a problem retrieving the FQDN of a host because ↵Robert James Kaes1-3/+4
I was passing in an incorrect parameter to gethostbyaddr(). D'oh.
2002-05-27(opensock): Changed a comment around to better state what the code is ↵Robert James Kaes1-2/+2
actually doing.
2002-05-26Removed the DNS API calls and replaced them with the standardRobert James Kaes1-24/+15
gethostbyname() and gethostbyaddr() functions. This is possible because tinyproxy now uses a standard pre-forked() method.
2002-05-24Fixed some spelling mistakes, and removed the getpeer_ip() andRobert James Kaes1-67/+1
getpeer_string() functions as they've been replaced by the getpeer_information() function.
2002-05-23Changed the lookup_domain() function to use the new "dnsserver" API.Robert James Kaes1-255/+67
Also moved safe_write(), safe_read(), readline(), and write_message() functions into their own file.
2002-04-24bind_address has been moved inside the config structure. Fixed up aRobert James Kaes1-5/+6
problem where "data" was being freed even if it had not been allocated (because of an error condition.)
2002-04-22The "Bind" directive sets a binding address which the outgoing connectionsRobert James Kaes1-4/+4
will use.
2002-04-18Whoops. The previous include only had the code conditionally removed.Robert James Kaes1-9/+1
Remove for real this time.
2002-04-18Removed the call to inet_aton() since the gethostbyname() function handlesRobert James Kaes1-1/+3
the dotted-decimal case itself.
2002-04-18Removed the call to hstrerror() in the getpeer_string() function. It'sRobert James Kaes1-3/+2
not available on all machines.
2002-04-17Removed the LOOKUP_LOCK() and LOOKUP_UNLOCK() macros since I believe IRobert James Kaes1-12/+4
need locking around both gethostbyname() and gethostbyaddr() at the same time.
2002-04-16Tightened the lookup_domain() function.Robert James Kaes1-3/+2
2002-04-15Added a test to make sure the "whole_buffer" could be allocated.Robert James Kaes1-3/+5
2002-04-13Added additional error handling for the bind() and listen() system callsRobert James Kaes1-3/+11
when setting up the listening socket.
2002-04-13Modified the opensock() function to respect the Listen directive. If it'sRobert James Kaes1-1/+17
set, bind all outgoing addresses to this local address.
