2007-10-10r21723: Make use of the per-hashchain "freelists"Volker Lendecke1-0/+3
(This used to be commit f3421ae4cfa263c0e7a8e934b40342ee9885d239)
2007-10-10r21115: notify_internal.c needs to remove the table entry if a process has ↵Volker Lendecke1-38/+62
crashed. So it needs the specific error message. Make messages.c return NTSTATUS and specificially NT_STATUS_INVALID_HANDLE if sending to a non-existent process. Volker (This used to be commit 3f620d181da0c356c8ffbdb5b380ccab3645a972)
2007-10-10r21081: Add forgotten functionVolker Lendecke1-0/+11

2007-10-10r21076: Two pieces of infrastructure from Samba4: An API-compatible ↵Volker Lendecke1-0/+121
messaging wrapper and tdb_wrap_open. Volker (This used to be commit c01f164dcaf88fb7f3bed8f69b210ba8fab326d1)
2007-10-10r21064: The core of this patch isVolker Lendecke1-5/+12
void message_register(int msg_type, void (*fn)(int msg_type, struct process_id pid, - void *buf, size_t len)) + void *buf, size_t len, + void *private_data), + void *private_data) { struct dispatch_fns *dfn; So this adds a (so far unused) private pointer that is passed from message_register to the message handler. A prerequisite to implement a tiny samba4-API compatible wrapper around our messaging system. That itself is necessary for the Samba4 notify system. Yes, I know, I could import the whole Samba4 messaging system, but I want to do it step by step and I think getting notify in is more important in this step. Volker (This used to be commit c8ae60ed65dcce9660ee39c75488f2838cf9a28b)
2007-10-10r20174: If we're only going to call one handler per messageJeremy Allison1-4/+4
then terminate the traversal once we've done that. Jeremy. (This used to be commit da3d0b62340b545950ea2081f30c252fd4609981)
2007-10-10r20165: Change messaging subsystem to only allow one messageJeremy Allison1-3/+11
per type - this is all we use right now and makes re-entrancy problems with deleting handlers with a message dispatch loop go away. Jeremy. (This used to be commit 2e9b6faeae1474d65a5c12f5a19b0ae045d47c2e)
2007-10-10r20160: Fix long-standing (ie. from initial code I think) bugJeremy Allison1-2/+5
in tdb message processing. If we're inside a dispatch function and we delete our own handler we'd walk onto the next pointer from a deleted memory block. Fixes crash bug in winbindd (and goodness knows where else). Jeremy. (This used to be commit 27a4c1121404e346432d90b97b518861e038e9f2)
2007-10-10r17316: More C++ warnings -- 456 leftVolker Lendecke1-2/+2
(This used to be commit 1e4ee728df7eeafc1b4d533240acb032f73b4f5c)
2007-10-10r17294: Make the code a little cleaner. Instead of using the twoJeremy Allison1-7/+4
calls make it : become_root_uid_only() operation unbecome_root_uid_only() saving errno across the second call. Most of our internal change calls can be replaced with these simple calls. Jeremy (This used to be commit 4143aa83c029848d8ec741d9218b3fa6e3fd28dd)
2007-10-10r17293: After the results from the cluster tests in Germany,Jeremy Allison1-4/+24
fix the messaging code to call the efficient calls : save_re_uid() set_effective_uid(0); messaging_op restore_re_uid(); instead of using heavyweight become_root()/unbecome_root() pairs around all messaging code. Fixup the messaging code to ensure sec_init() is called (only once) so that non-root processes still work when sending messages. This is a lighter weight solution to become_root()/unbecome_root() (which swaps all the supplemental groups) and should be more efficient. I will migrate all server code over to using this (a similar technique should be used in the passdb backend where needed). Jeremy. (This used to be commit 4ace291278d9a44f5c577bdd3b282c1231e543df)
2007-10-10r17231: Some patch cosmeticsVolker Lendecke1-1/+1

2007-10-10r16390: Klocwork #604 - ensure if NULL pointer we assertJeremy Allison1-2/+8
if len != 0. Jeremy. (This used to be commit e99cedfb0cabe3863797c8bd4594ee0826022d2e)
2007-10-10r15003: patch based on code from Arkady Glabek <aglabek@centeris.com> to ↵Gerald Carter1-0/+18
ensure that global memory is freed when unloading pam_winbind.so (needs more testing on non-linux platforms) (This used to be commit 1e0b79e591d70352a96e0a0487d8f394dc7b36ba)

* \PIPE\unixinfo * winbindd's {group,alias}membership new functions * winbindd's lookupsids() functionality * swat (trunk changes to be reverted as per discussion with Deryck) (This used to be commit 939c3cb5d78e3a2236209b296aa8aba8bdce32d3)
2007-10-10r9619: Fix messages_pending_for_pid actually do what it's meant to do. This ↵Volker Lendecke1-1/+1
might be a big relief on messages.tdb contention as ignoring processes with >1000 messages in printing/notify.c should work correctly now. Jeremy, Jerry told me to ask you about printer scalability torture tests, this might be a reason why you implemented the message_send_pid_with_timeout using the signal (shudder) in the first place. :-) While looking at that... Wouldn't it be better to not use the signal but have an overall timeout for print_notify_send_messages using GetTimeOfDay & friends and not use the alarm signal deep inside tdb.c? Volker (This used to be commit b5e82bb512d3425839e061e78f4d6fe0bd05b708)
2007-10-10r7440: * merge registry server changes from trunk (so far) for moreGerald Carter1-1/+1

2007-10-10r4088: Get medieval on our ass about malloc.... :-). Take control of all our ↵Jeremy Allison1-2/+2
allocation functions so we can funnel through some well known functions. Should help greatly with malloc checking. HEAD patch to follow. Jeremy. (This used to be commit 620f2e608f70ba92f032720c031283d295c5c06a)
2007-10-10r1885: tighten the cache consistency with the ntprinters.tdb entry an the in ↵Gerald Carter1-2/+4
memory cache associated with open printer handles; also make sure that register_messages_flags() doesn't overwrite the originally registers flags (This used to be commit 540daf71d8ad189af5dd6d45aa1ce2b3d67da752)

2003-01-30Add 3 second timeout when terminating server and sending print notifyJeremy Allison1-5/+45
messages. Stops build-up of large numbers of smbd's waiting to terminate on large print throughput. Jeremy. (This used to be commit 07efebb98473cb3d4adc6b2e0afef3f06dcc99b8)
2003-01-30Merge of REQ_DEBUGLEVEL messaging and debug_count fixes from HEAD.Tim Potter1-11/+0
(This used to be commit abb112ba2ad362036c7b3f340d5f64d6fcc0cd3c)
2003-01-11Added new message_send_pid() code that uses tdb append to reduce lockingJeremy Allison1-54/+55
contention on the messaging tdb. Jeremy. (This used to be commit ee0ceeff99f32146bebd4b49d346abdaa20aa10c)
2003-01-10First part of efficiency fixes for message sending to pid's (cutting downJeremy Allison1-48/+95
the amount of time we hold tdb locks). Gulp down all messages at once rather than reading/re-writing one at a time. NOTE: All dispatch routines *must* be able to cope with incoming message on *odd* byte boundaries (all current handlers do). Jeremy. (This used to be commit b752c0340f96669b2b2573cf7d3d10f99580b070)
2003-01-03Merge from HEAD - make Samba compile with -Wwrite-strings without additionalAndrew Bartlett1-1/+1

2002-03-20Add assertions that kill() is never accidentally passed a non-positiveMartin Pool1-0/+7
pid. This follows a bug in rsync where it would accidentally kill(-1), removing all the user's processes. I can't see any way this would directly happen in Samba, but having the assertions seems beneficial. http://cvs.samba.org/cgi-bin/cvsweb/rsync/util.c.diff?r1=1.108&r2=1.109&f=h (This used to be commit 098905bea29c7d5b886809d431294ddf2fc1e152)

2002-02-18serialise all domain auth requestsAndrew Tridgell1-0/+30
this is needed because W2K will send a TCP reset to any open connections that have not done a negprot when a second connection is made. This meant that under heavy netlogon load a Samba domain member would fail authentications. Jeremy, you may wish to port this to 2.2.x (This used to be commit eb196070e62b45b113e5712f27198c50c5c95657)
