2008-09-24Fix nasty bug that would come up only if a client connection to a remoteSimo Sorce1-6/+7
ldap server suddenly dies. We were creating a wrong talloc hierarchy, so the event.fde was not freed automatically as expected. This in turn made the event system call the ldap io handlers with a null packet structure, causing a segfault. Fix also the ordering in ldap_connection_dead() Thanks to Metze for the huge help in tracking down this one.

2007-10-10r23792: convert Samba4 to GPLv3Andrew Tridgell1-3/+2
There are still a few tidyups of old FSF addresses to come (in both s3 and s4). More commits soon. (This used to be commit fcf38a38ac691abd0fa51b89dc951a08e89fdafa)

2007-10-10r18301: I discovered how to load the warnings from a build farm build intoAndrew Tridgell1-1/+1
emacs compile mode (hint, paste to a file, and compile as "cat filename"). This allowed me to fix nearly all the warnings for a IA_64 SuSE build very quickly. (This used to be commit eba6c84efff735bb0ca941ac4b755ce2b0591667)

2007-10-10r18068: This splits the handling of multiple SASL packets between the GENSECAndrew Bartlett1-44/+126
backend (if it chooses to implement it), or the GENSEC socket code. This is to allow us to handle DIGEST-MD5 across to cyrus-sasl. Andrew Bartlett (This used to be commit 0a098006b431f4aa48632a27ca08e9adca8d9609)
2007-10-10r17222: Change the function prototypes for the GENSEc and TLS socket creationAndrew Bartlett1-33/+60
routines to return an NTSTATUS. This should help track down errors. Use a bit of talloc_steal and talloc_unlink to get the real socket to be a child of the GENSEC or TLS socket. Always return a new socket, even for the 'pass-though' case. Andrew Bartlett (This used to be commit 003e2ab93c87267ba28cd67bd85975bad62a8ea2)
2007-10-10r17197: This patch moves the encryption of bulk data on SASL negotiated securityAndrew Bartlett1-0/+421
contexts from the application layer into the socket layer. This improves a number of correctness aspects, as we now allow LDAP packets to cross multiple SASL packets. It should also make it much easier to write async LDAP tests from windows clients, as they use SASL by default. It is also vital to allowing OpenLDAP clients to use GSSAPI against Samba4, as it negotiates a rather small SASL buffer size. This patch mirrors the earlier work done to move TLS into the socket layer. Unusual in this pstch is the extra read callback argument I take. As SASL is a layer on top of a socket, it is entirely possible for the SASL layer to drain a socket dry, but for the caller not to have read all the decrypted data. This would leave the system without an event to restart the read (as the socket is dry). As such, I re-invoke the read handler from a timed callback, which should trigger on the next running of the event loop. I believe that the TLS code does require a similar callback. In trying to understand why this is required, imagine a SASL-encrypted LDAP packet in the following formation: +-----------------+---------------------+ | SASL Packet #1 | SASL Packet #2 | ----------------------------------------+ | LDAP Packet #1 | LDAP Packet #2 | ----------------------------------------+ In the old code, this was illegal, but it is perfectly standard SASL-encrypted LDAP. Without the callback, we would read and process the first LDAP packet, and the SASL code would have read the second SASL packet (to decrypt enough data for the LDAP packet), and no data would remain on the socket. Without data on the socket, read events stop. That is why I add timed events, until the SASL buffer is drained. Another approach would be to add a hack to the event system, to have it pretend there remained data to read off the network (but that is ugly). In improving the code, to handle more real-world cases, I've been able to remove almost all the special-cases in the testnonblock code. The only special case is that we must use a deterministic partial packet when calling send, rather than a random length. (1 + n/2). This is needed because of the way the SASL and TLS code works, and the 'resend on failure' requirements. Andrew Bartlett (This used to be commit 5d7c9c12cb2b39673172a357092b80cd814850b0)
