2010-07-19Move the addition of the 16 byte guid out of spnego_gen_negTokenInit() andJeremy Allison1-23/+32
into negprot_spnego() where it belongs (it's not an SPNEGO operation). Add a TALLOC_CTX for callers of negprot_spnego(). Closer to unifying all the gen_negTokenXXX calls. Jeremy.
2010-07-19s3-auth: Simplify how we free the auth_contextSimo Sorce1-2/+1
Turn the freeing function into a destructor and attach it to the auth_context. Make all callers TALLOC_FREE() the auth_context instead of calling the free function. Signed-off-by: Andrew Bartlett <abartlet@samba.org>

2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke1-2/+2
When a samba server process dies hard, it has no chance to clean up its entries in locking.tdb, brlock.tdb, connections.tdb and sessionid.tdb. For locking.tdb and brlock.tdb Samba is robust by checking every time we read an entry from the database if the corresponding process still exists. If it does not exist anymore, the entry is deleted. This is not 100% failsafe though: On systems with a limited PID space there is a non-zero chance that between the smbd's death and the fresh access, the PID is recycled by another long-running process. This renders all files that had been locked by the killed smbd potentially unusable until the new process also dies. This patch is supposed to fix the problem the following way: Every process ID in every database is augmented by a random 64-bit number that is stored in a serverid.tdb. Whenever we need to check if a process still exists we know its PID and the 64-bit number. We look up the PID in serverid.tdb and compare the 64-bit number. If it's the same, the process still is a valid smbd holding the lock. If it is different, a new smbd has taken over. I believe this is safe against an smbd that has died hard and the PID has been taken over by a non-samba process. This process would not have registered itself with a fresh 64-bit number in serverid.tdb, so the old one still exists in serverid.tdb. We protect against this case by the parent smbd taking care of deregistering PIDs from serverid.tdb and the fact that serverid.tdb is CLEAR_IF_FIRST. CLEAR_IF_FIRST does not work in a cluster, so the automatic cleanup does not work when all smbds are restarted. For this, "net serverid wipe" has to be run before smbd starts up. As a convenience, "net serverid wipedbs" also cleans up sessionid.tdb and connections.tdb. While there, this also cleans up overloading connections.tdb with all the process entries just for messaging_send_all(). Volker

2009-02-21Remove the static "chal" from ntlmssp.c:get_challenge()Volker Lendecke1-3/+2
2009-02-01Add two new parameters to control how we verify kerberos tickets. Removes ↵Dan Sledz1-1/+1
lp_use_kerberos_keytab parameter. The first is "kerberos method" and replaces the "use kerberos keytab" with an enum. Valid options are: secrets only - use only the secrets for ticket verification (default) system keytab - use only the system keytab for ticket verification dedicated keytab - use a dedicated keytab for ticket verification. secrets and keytab - use the secrets.tdb first, then the system keytab For existing installs: "use kerberos keytab = yes" corresponds to secrets and keytab "use kerberos keytab = no" corresponds to secrets only The major difference between "system keytab" and "dedicated keytab" is that the latter method relies on kerberos to find the correct keytab entry instead of filtering based on expected principals. The second parameter is "dedicated keytab file", which is the keytab to use when in "dedicated keytab" mode. This keytab is only used in ads_verify_ticket.

2008-05-20Cleanup size_t return values in callers of convert_string_allocateTim Prouty1-2/+3
This patch is the second iteration of an inside-out conversion to cleanup functions in charcnv.c returning size_t == -1 to indicate failure. (This used to be commit 6b189dabc562d86dcaa685419d0cb6ea276f100d)

2007-10-10r24809: Consolidate the use of temporary talloc contexts.Volker Lendecke1-1/+1
This adds the two functions talloc_stackframe() and talloc_tos(). * When a new talloc stackframe is allocated with talloc_stackframe(), then * the TALLOC_CTX returned with talloc_tos() is reset to that new * frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse * happens: The previous talloc_tos() is restored. * * This API is designed to be robust in the sense that if someone forgets to * TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and * resets the talloc_tos(). The original motivation for this patch was to get rid of the sid_string_static & friends buffers. Explicitly passing talloc context everywhere clutters code too much for my taste, so an implicit talloc_tos() is introduced here. Many of these static buffers are replaced by a single static pointer. The intended use would thus be that low-level functions can rather freely push stuff to talloc_tos, the upper layers clean up by freeing the stackframe. The more of these stackframes are used and correctly freed the more exact the memory cleanup happens. This patch removes the main_loop_talloc_ctx, tmp_talloc_ctx and lp_talloc_ctx (did I forget any?) So, never do a tmp_ctx = talloc_init("foo"); anymore, instead, use tmp_ctx = talloc_stackframe() :-) Volker (This used to be commit 6585ea2cb7f417e14540495b9c7380fe9c8c717b)

2007-10-10r24135: Convert call_trans2open to the new APIVolker Lendecke1-0/+1
This itself won't help much, because send_trans2_replies_new still allocates the big buffers, but stay tuned :-) Also add/update my copyright on stuff I recently touched. Volker (This used to be commit 248f15ff143474db2493cef89ba446892342a361)

2007-10-10r24006: Some more paranoia in reply_negprotVolker Lendecke1-2/+12
Some hosts see the smb_bufrem(req->inbuf, p) as an unsigned int. And as the p += strlen(p) + 2 went one beyond the buffer, this was a very large positive. Also take the chance to add one more consistency check. (This used to be commit 3673707f9f1a3ba29966ac7cf744e2b6462c8dde)

2007-10-10r21250: Partial fix for BUG 4093: Make %a expand to "Vista"Gerald Carter1-8/+37
based on the flags2 values in the negprot request. This also includes some code for testing the dialect strings for "SMB 2.001" but this is unreliable as Vista only sends that in the 1st negprot and caches the fact that we don't support it. Restartnig the WOrkstation service on the client clears the cache. (This used to be commit d781eeb0e4362b7af1497634d26315498a5257d4)
