* Rely on /dev/urandomVolker Lendecke2015-10-131-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | This removes quite a bit of code. All reasonable systems have /dev/urandom these days. Linux, Solaris and the BSDs do. In case we find a system without /dev/urandom, we will have to go hunting in other libraries. The main reason for this is speed: On Ubuntu 14.04 doing direct reads from /dev/urandom is 2-3 times faster than our md4 based code. On virtualized FreeBSD 10 the difference is even larger. My first approach was to use fopen/fread. It was even faster, but less than twice as fast. So I thought we could save the additional complexity when having to deal with throwing away buffers when forking and the additional memory footprint per process. With this simple generate_random_buffer it will be easier to adapt new syscalls to get randomness.

* s4-process_model: Do not close random fds while forking.Andreas Schneider2015-03-271-3/+9
| | | | | | | | | | | | | | | | | | | | BUG: https://bugzilla.samba.org/show_bug.cgi?id=11180 The issue has been found with nss_wrapper debug output running: samba4.ntvfs.cifs.krb5.base.lock In the case here, we fork a child and close the fd without resetting the pipe fd variable. Then the fd was used to open the nss_wrapper hosts file which got the same fd. We forked again in the process model called close() on the re-used fd (of the pipe variable) again without nss_wrapper noticing. Now Samba opened the secrets tdb and got the same fd as nss_wrapper was using for the hosts file and next nss_wrapper tried to parse a TDB ...

* s4-process_standard: Remove signal(SIGCHLD, SIG_IGN)Andrew Bartlett2015-03-171-2/+174
| | | | | | | | | | | | | We replace this with a pipe between parent and child, and then watch for a read event in the parent to indicate that the child has gone away. The removal of signal(SIGCHLD, SIG_IGN) requires us to then call waitpid(). We can't do that in a main loop as we want to get the exit status to the legitimate waitpid calls in routines like samba_runcmd_*().

* ensure that child tasks die when the parent diesAndrew Tridgell2009-08-071-0/+24
| | | | | | | | | | | | | Previously we relied on process groups and SIGTERM to ensure that child tasks died in the standard process model when the parent task died. This doesn't work when the server is run in interactive mode, as in that case we don't call become_daemon() and don't get a separate process group. The fix is to have a pipe held open by the parent server process, and inherited by child tasks. If the parent exits then the write side of the pipe is implicitly closed, which causes an event in the child tasks that causes them to exit

* Remaining changes to implement the prefork process modelAndrew Bartlett2008-02-041-5/+6
| | | | | | | | | | | | | | | | | | | To use, run 'smbd -M prefork' By default, only the smb service is preforked. 4 children are created, and all listen for new connections. The Linux Kernel 'wake one' behaviour should ensure that only one is given the oportunity to accept. We need to look into the ideal number of worker children, as well as load balancing behaviours. To change, set: prefork children : smb = 6 valid service names (smb in this example) match those in 'server services'.

| | | | | | | | | | | | | | | | | | | This merges Samba4 with lorikeet-heimdal, which itself has been tracking Heimdal CVS for the past couple of weeks. This is such a big change because Heimdal reorganised it's internal structures, with the mechglue merge, and because many of our 'wishes' have been granted: we now have DCE_STYLE GSSAPI, send_to_kdc hooks and many other features merged into the mainline code. We have adapted to upstream's choice of API in these cases. In gensec_gssapi and gensec_krb5, we either expect a valid PAC, or NO PAC. This matches windows behavour. We also have an option to require the PAC to be present (which allows us to automate the testing of this code). This also includes a restructure of how the kerberos dependencies are handled, due to the fallout of the merge. Andrew Bartlett (This used to be commit 4826f1735197c2a471d771495e6d4c1051b4c471)
