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)

2007-10-10r21076: 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)

ensure that global memory is freed when unloading pam_winbind.so (needs more testing on non-linux platforms) (This used to be commit 1e0b79e591d70352a96e0a0487d8f394dc7b36ba)

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)

2007-10-10r4088: 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)

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)
