2013-03-04s4-lib/socket: Return the original EMSGSIZE when sendto() and setsockopt() ↵Andrew Bartlett1-1/+1
both fail This ensures that should we be unable to increase the socket size, we return an error that the application layer above might expect and be able to make as reasonable response to (such as switching to a stream-based transport). This fixes up c692bb02b039ae8fef6ba968fd13b36ad7d62a72. As suggested by metze in https://bugzilla.samba.org/show_bug.cgi?id=9697#c4 Andrew Bartlett Reviewed-by: Stefan Metzmacher <metze@samba.org>

2013-03-04samba_upgradeprovision: Do not reset every DN when changing an SDAndrew Bartlett1-22/+8
SD propogation is handled by an LDB module, we do not need to touch each and every DN to make it happen. Now that we do not need to put this via a hash, the dnToRecalculate list is changed to be a list of Dn objects, not strings so that: if dn in listWellknown is handled using a schema comparison (avoiding different case forms tripping it up).

2013-03-02Handle EMSGSIZE on UNIX domain sockets.Landon Fuller1-9/+26
On some systems (eg, FreeBSD) the default SO_SNDBUF for UNIX domain sockets is to small, and EMSGSIZE is returned. Other systems provide a larger default send buffer, but there is still no guarantee that the buffer will be sized appropriately. This patch modifies the sendto() path to attempt to resize the SO_SNDBUF dynamically upon an EMSGSIZE failure, and then retry the send.

2013-03-02tevent: change version to 0.9.18Stefan Metzmacher2-1/+84
This release contains a lot of fixes: - Adding new timer events is now faster, if there's a large number of timer events. - sigprocmask does not work on FreeBSD to stop further signals in a signal handler. - TEVENT_NUM_SIGNALS is calculated by configure in order to support realtime signals on freebsd. - ./configure --disable-python was fixed for the standalone build. - Several crash bugs in the poll backend are fixed. - The poll backend removes deleted events from the cached pollfd array now. - The poll doesn't pass pollfd.events == 0 to poll() and maintains a list of disabled events, instead of consuming 100% cpu and/or triggering the callers handler. - The poll backend detects POLLNVAL and reports EBADF instead of consuming 100% cpu. - The select backend supports separate handlers for TEVENT_FD_READ and TEVENT_FD_WRITE. - The poll and select backends are now doing fair queuing of fd events. - The epoll has better error checking and supports separate handlers for TEVENT_FD_READ and TEVENT_FD_WRITE. - The standard backend was rewritten to be a tiny wrapper on top of epoll with a fallback to poll, which means that it doesn't use select directly anymore. - TEVENT_TRACE_BEFORE_LOOP_ONCE and TEVENT_TRACE_AFTER_LOOP_ONCE are added in order to allow the application to hook in before and after the loop_once() backend function is called. The TEVENT_HAS_LOOP_ONCE_TRACE_POINTS define can be used to detect the new feature.

2013-03-01tevent: optimize adding new zero timer eventsStefan Metzmacher6-31/+113
Such events were used before we had immediate events. It's likely that there're a lot of this events and we need to add new ones in fifo order. The tricky part is that tevent_common_add_timer() should not use the optimization as it's used by broken Samba versions, which don't use tevent_common_loop_timer_delay() in source3/lib/events.c.

2013-03-01tevent: optimize adding new timer eventsStefan Metzmacher1-8/+24
As new timestamps typically get higher:-) it's better to traverse the existing list from the tail. This is not completely optimal, but it should be better than before. A second optimization could be done for zero timestamps, we would just remember the last_zero_timer, but that would change the internal ABI. Normally thatshould not be a poblem, but the Samba's source3/lib/events.c abuses tevent_internal.h from the current source tree, even if an external tevent.h is used. The other problem is that it makes use of tevent_common_add_timer() without using tevent_common_loop_timer_delay().
