2009-02-13Remove typedef struct blocking_lock_record and move references to struct ↵Zack Kirsch1-19/+19
blocking_lock_record.
2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-2/+4
This changelist allows for the addition of custom performance monitoring modules through smb.conf. Entrypoints in the main message processing code have been added to capture the command, subop, ioctl, identity and message size statistics.
2009-01-31Remove the global variable "chain_size"Volker Lendecke1-6/+1
2009-01-16Add a new implementation of chain_replyVolker Lendecke1-6/+0
This the global variable "orig_inbuf" in the old chain_reply code. This global variable was one of the reasons why we had the silly restriction to not allow async requests within a request chain.
2009-01-08s3:smbd: move all globals and static variables in globals.[ch]Stefan Metzmacher1-15/+6
The goal is to move all this variables into a big context structure. metze
2009-01-05s3:events: change event_add_timed() prototype to match samba4Stefan Metzmacher1-2/+2

2008-11-08Do not write into inbuf for the transs requestVolker Lendecke1-1/+0
Instead, fix up the outbuf in send_xx_reply. In those routines, we know what we are returning.
2008-11-08Remove the change to the user context in process_blocking_lock_queue()Volker Lendecke1-76/+8
2008-11-04Convert blocking.c to store a smb_request instead of just inbufVolker Lendecke1-88/+54
2008-11-04Simplify logic of cancel_pending_lock_requests_by_fid()Volker Lendecke1-20/+18
The only caller of this function is locking_close_file(). This checks itself if brl_lock != NULL. The additional check is not necessary here.
2008-11-04Slightly simplify logic in process_lockingX()Volker Lendecke1-7/+8
The "else" is pointless here, we did a "return True" in the if branch.
2008-11-04Slightly simplify logic in remove_pending_lock_requests_by_mid()Volker Lendecke1-13/+21
Use "continue" for (SVAL(blr->inbuf,smb_mid) != mid)
2008-11-04Slightly simplify logic in cancel_pending_lock_requests_by_fid()Volker Lendecke1-20/+24
Use a "continue" for (blr->fsp->fnum != fsp->fnum)
2008-11-04Convert blocking.c to use tallocVolker Lendecke1-23/+15
2008-11-04Make "inbuf" a talloc child of "smb_request" for normal smb requestsVolker Lendecke1-0/+2
This is necessary if we want to keep the whole smb_request for deferred ops. The explicit settings of req->inbuf will be removed once all those deferring operations are converted to store the whole request and not just the inbuf.
2008-11-03Fix nonempty blank linesVolker Lendecke1-14/+14
2008-11-02Remove some inbuf references by adding "cmd" to smb_requestVolker Lendecke1-1/+1
2008-11-01Apply some const to get_lock_*()Volker Lendecke1-4/+6
2008-10-14Use {u,}int64_t instead of SMB_BIG_{U,}INT.Jelmer Vernooij1-12/+12
2008-10-13Remove the chain_fsp globalVolker Lendecke1-1/+0
2008-01-10Some more talloc_tos()Volker Lendecke1-5/+5
(This used to be commit 444e35e7df1f13fc285183da8fb41b30ad99a3fa)
2008-01-05Fix %d / size_t printf arg missmatch.Jeremy Allison1-2/+2
Jeremy. (This used to be commit 3e3205309b75edf7d29633525adfdceb5f8856eb)
2008-01-04Fix interesting bug found with make valgrindtest. When cancellingJeremy Allison1-10/+14
a lock due to file closure make sure we null out the fsp pointer so it isn't dangling. This is an old bug (not related to the new changes). Jeremy. (This used to be commit b5ee972b0c04b4d119573d95ac458a3b6be30c5c)
2008-01-04Refactor the crypto code after a very helpful conversationJeremy Allison1-13/+21
with Volker. Mostly making sure we have data on the incoming packet type, not stored in the smb header. Jeremy. (This used to be commit c4e5a505043965eec77b5bb9bc60957e8f3b97c8)
2007-10-30Add new parameter, "min receivefile size" (by default setJeremy Allison1-2/+2
to zero). If non-zero, writeX calls greater than this value will be left in the socket buffer for later handling with recvfile (or userspace equivalent). Definition of recvfile for your system is left as an exercise for the reader (I'm working on getting splice working :-). Jeremy. (This used to be commit 11c03b75ddbcb6e36b231bb40a1773d1c550621c)
2007-10-18RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison1-15/+15
bugs in various places whilst doing this (places that assumed BOOL == int). I also need to fix the Samba4 pidl generation (next checkin). Jeremy. (This used to be commit f35a266b3cbb3e5fa6a86be60f34fe340a3ca71f)
2007-10-10r24809: Consolidate the use of temporary talloc contexts.Volker Lendecke1-2/+2
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)
2007-10-10r24791: Fix logic error in timeout of blocking lock processing found byJeremy Allison1-22/+29
Ronnie. If a lock timeout expires, we must check we can get the lock before responding with failure. Volker is writing a torture test. Jeremy. (This used to be commit 45380f356b99d575645873b05af17c504b091dc8)
2007-10-10r24702: Remove the old API pointersVolker Lendecke1-3/+1

2007-10-10r24404: Remove get_OutBuffer usage from blocking.cVolker Lendecke1-27/+14
(This used to be commit cb8fab5663db2cb408e1b85a7287d3670b09d503)
2007-10-10r24163: Remove the send_trans2_replies_new wrapperVolker Lendecke1-1/+1
This changes send_trans2_replies to not depend on large buffers anymore and finishes the trans2 conversion. (This used to be commit b1d133e4ffa8c9b8219ba6e7b83e23ca4bdd1616)
2007-10-10r24160: process_trans2 in smbd/blocking.c used send_trans2_replies.Volker Lendecke1-6/+11
Fake a struct smb_request here. Volker (This used to be commit f712d1c92bee024a165b5facabdac1e2c866d9b1)

2007-10-10r23997: Check in the infrastructure for getting rid of the global ↵Volker Lendecke1-1/+1
InBuffer/OutBuffer The complete history of this patch can be found under http://www.samba.org/~vlendec/inbuf-checkin/. Jeremy, Jerry: If possible I would like to see this in 3.2.0. I'm only checking into 3_2 at the moment, as it currently will slow down operations for all non-converted (i.e. all at this moment) operations, as it will copy the talloc'ed inbuf over the global InBuffer. It will need quite a bit of effort to convert everything necessary for the normal operations an XP box does. I have patches for negprot, session setup, tcon_and_X, open_and_X, close. More to come, but I would appreciate some help here. Volker (This used to be commit 5594af2b208c860d3f4b453af6a649d9e4295d1c)

Jeremy. (This used to be commit 407e6e695b8366369b7c76af1ff76869b45347b3)
2007-10-10r23510: Tidy calls to smb_panic by removing trailing newlines. Print theJames Peach1-2/+2

2007-10-10r23014: For all branches, ensure that if we're blocked on a POSIXJeremy Allison1-4/+21
lock we know nothing about that we retry the lock every 10 seconds instead of waiting for the standard select timeout. This is how we used to (and are supposed to) work. Jeremy. (This used to be commit fa18fc25a50cf13c687ae88e7e5e2dda1120e017)

2007-10-10r22846: Chunk one to replace message_send_pid with messaging_send: Deep insideVolker Lendecke1-4/+7
locking/locking.c we have to send retry messages to timed lock holders. The majority of this patch passes a "struct messaging_context" down there. No functional change, survives make test. (This used to be commit bbb508414683eeddd2ee0d2d36fe620118180bbb)
2007-10-10r22736: Start to merge the low-hanging fruit from the now 7000-line cluster ↵Volker Lendecke1-3/+3
patch. This changes "struct process_id" to "struct server_id", keeping both is just too much hassle. No functional change (I hope ;-)) Volker (This used to be commit 0ad4b1226c9d91b72136310d3bbb640d2c5d67b8)
2007-10-10r22391: Looks bigger than it is. Make "inbuf" availableJeremy Allison1-3/+3
to all callers of smb_setlen (via set_message() calls). This will allow the server to reflect back the correct encryption context. Jeremy. (This used to be commit 2d80a96120a5fe2fe726f00746d36d85044c4bdb)
2007-10-10r22389: Start preparing for multiple encryption contexts in theJeremy Allison1-5/+7
server. Allow server to reflect back to calling client the encryption context that was sent. Jeremy. (This used to be commit b49e90335d1e589916b5ab4992e3c4a2d221ca7e)
2007-10-10r21879: Move process_blocking_lock_queue to a timed event.Volker Lendecke1-45/+71
The idea is that we have blocking.c:brl_timeout as a timed event that is present whenever we do have a blocking lock pending. It fires brl_timeout_fn() which calls process_blocking_lock_queue(). Whenever we make changes to blocking_lock_queue, we trigger a recalc_brl_timeout() which sets a new brl_timout event if necessary. This makes the call to blocking_locks_timeout_ms() in setup_select_timeout() unnecessary, this is implicitly done in event_add_to_select_args() from the timed events. Volker (This used to be commit 7e31b8ce21de803ac1f8967967393341a3f44ac3)
2007-10-10r21064: The core of this patch isVolker Lendecke1-6/+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)
