2012-02-03s3-nmbd: don't discard DGRAM frames from local addresses when we are a DCMatthieu Patou1-15/+17
Winbind use netbios to locate the DC, if samba is also a DC then nmbd receive request from Winbind that are from a local address, those requests must not be discarded otherwise winbind can't find the DC and won't try another method.

2010-11-14Fix the unexpected.tdb database problem. Change nmbd to store theJeremy Allison1-2/+5
transaction id of packets it was requested to send via a client, and only store replies that match these ids. On the client side change clients to always attempt to ask nmbd first for name_query and node_status calls, and then fall back to doing socket calls if we can't talk to nmbd (either nmbd is not running, or we're not root and cannot open the messaging tdb's). Fix readers of unexpected.tdb to delete packets they've successfully read. This should fix a long standing problem of unexpected.tdb growing out of control in noisy NetBIOS envioronments with lots of bradcasts, yet still allow unprivileged client apps to work mostly as well as they already did (nmblookup for example) in an environment when nmbd isn't running.

2010-10-01s3:events: Call all ready fd event handlers on each iteration of the main loopSteven Danneman1-3/+3
Previously, only one fd handler was being called per main message loop in all smbd child processes. In the case where multiple fds are available for reading the fd corresponding to the event closest to the beginning of the event list would be run. Obviously this is arbitrary and could cause unfairness. Usually, the first event fd is the network socket, meaning heavy load of client requests can starve out other fd events such as oplock or notify upcalls from the kernel. In this patch, I have changed the behavior of run_events() to unset any fd that it has already called a handler function, as well as decrement the number of fds that were returned from select(). This allows the caller of run_events() to iterate it, until all available fds have been handled. I then changed the main loop in smbd child processes to iterate run_events(). This way, all available fds are handled on each wake of select, while still checking for timed or signalled events between each handler function call. I also added an explicit check for EINTR from select(), which previously was masked by the fact that run_events() would handle any signal event before the return code was checked. This required a signature change to run_events() but all other callers should have no change in their behavior. I also fixed a bug in run_events() where it could be called with a selrtn value of -1, doing unecessary looping through the fd_event list when no fds were available. Also, remove the temporary echo handler hack, as all fds should be treated fairly now.

2010-02-10More of the fix for bug #7118 - nmbd problems with socket address.Jeremy Allison1-0/+89
Add a simple "processed packet queue" cache to stop nmbd responding to packets received on the broadcast and non-broadcast socket (which it has opened when "nmbd bind explicit broadcast = yes"). This is a very simple packet queue - it only keeps the packets processed during a single call to listen_for_packets() (i.e. one select call). This means that if the delivery notification for a packet received on both broadcast and non-broadcast addresses is done in two different select calls, the packet will still be processed twice. This is a very rare occurrance and we can just live with it when it does as the protocol is stateless. If this is ever flagged as a repeatable problem then we can add a longer lived cache, using timeout processing to clear etc. etc. But without storing all packets processed we can never be *sure* we've eliminated the race condition so I'm going to go with this simple solution until someone proves a more complex one is needed :-). Jeremy.

== Subject: Remote code execution in Samba's WINS == server daemon (nmbd) when processing name == registration followed name query requests. == == CVE ID#: CVE-2007-5398 == == Versions: Samba 3.0.0 - 3.0.26a (inclusive) ... Secunia Research reported a vulnerability that allows for the execution of arbitrary code in nmbd. This defect may only be exploited when the "wins support" parameter has been enabled in smb.conf.

2007-10-24This is a large patch (sorry). Migrate from struct in_addrJeremy Allison1-2/+2
to struct sockaddr_storage in most places that matter (ie. not the nmbd and NetBIOS lookups). This passes make test on an IPv4 box, but I'll have to do more work/testing on IPv6 enabled boxes. This should now give us a framework for testing and finishing the IPv6 migration. It's at the state where someone with a working IPv6 setup should (theorecically) be able to type : smbclient //ipv6-address/share and have it work. Jeremy.

IPv6 in winbindd, but moves most of the socket functions that were wrongly in lib/util.c into lib/util_sock.c and provides generic IPv4/6 independent versions of most things.
