| | | | | | | 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.
* Refactor the crypto code after a very helpful conversationJeremy Allison2008-01-041-13/+21
| | | | | | with Volker. Mostly making sure we have data on the incoming packet type, not stored in the smb header. Jeremy.
* Add new parameter, "min receivefile size" (by default setJeremy Allison2007-10-301-2/+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.
* RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison2007-10-181-15/+15

* r24809: Consolidate the use of temporary talloc contexts.Volker Lendecke2007-10-101-2/+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
* r24791: Fix logic error in timeout of blocking lock processing found byJeremy Allison2007-10-101-22/+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.

| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | patch. This changes "struct process_id" to "struct server_id", keeping both is just too much hassle. No functional change (I hope ;-)) Volker

* r21879: Move process_blocking_lock_queue to a timed event.Volker Lendecke2007-10-101-45/+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
* r21064: The core of this patch isVolker Lendecke2007-10-101-6/+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

* r17541: When returning a trans2 request, if the "max dataJeremy Allison2007-10-101-1/+2
| | | | | | | | | | | | | | | | | bytes returned" is less than the amount we want to send, return what we can and set STATUS_BUFFER_OVERFLOW (doserror ERRDOS,ERRbufferoverflow). Required by OS/2 to handle EA's that are too large. It's hard to test this in Samba4 smbtorture as the max data bytes returned is hard coded at 0xffff (as it is in the Samba3 client libraries also). I used a custom version of Samba4 smbtorture to test this out. Might add a "max data bytes" param to make this testable in the build farm. Confirmed by "Guenter Kukkukk (sambaos2)" <sambaos2@kukkukk.com> and Andreas Taegener <atsamba11@eideltown.de> that this fixes the issue. Jeremy.
* r17314: Optimisation for POSIX locking. If we're downgradingJeremy Allison2007-10-101-1/+1
| | | | | | | a POSIX lock (applying a read-lock) and we overlap pending read locks then send them an unlock message, we may have allowed them to proceed. Jeremy.
* r17293: After the results from the cluster tests in Germany,Jeremy Allison2007-10-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* r17105: Fix the race Volker found - we had a non-lockedJeremy Allison2007-10-101-197/+64
| | | | | | | | | | | | | | | | | | | | | region between detecting a pending lock was needed and when we added the blocking lock record. Make sure that we hold the lock over all this period. Removed the old code for doing blocking locks on SMB requests that never block (the old SMBlock and friends). Discovered something interesting about the strange NT_STATUS_FILE_LOCK_CONFLICT return. If we asked for a lock with zero timeout, and we got an error of NT_STATUS_FILE_LOCK_CONFLICT, treat it as though it was a blocking lock with a timeout of 150 - 300ms. This only happens when timeout is sent as zero and can be seen quite clearly in ethereal. This is the real replacement for old do_lock_spin() code. Re-worked the blocking lock select timeout to correctly use milliseconds instead of the old second level resolution (far too coarse for this work). Jeremy.

* r1154: Change default setting for case sensitivity to "auto". If set to autoJeremy Allison2007-10-101-1/+1
| | | | | | | | | | | | then is the client supports it (current clients supported are Samba and CIFSVFS - detected by the negprot strings "Samba", "POSIX 2" and a bare "NT LM 0.12" string) then the setting of the per packet flag smb_flag FLAG_CASELESS_PATHNAMES is taken into account per packet. This allows the linux CIFS client to use Samba in a case sensitive manner. Additional command in smbclient "case_sensitive", toggles the flag in subsequent packets. Docs to follow. Jeremy.

* Turns out I had my packet sequences wrong for oplock break code.Jeremy Allison2003-08-071-1/+1
| | | | | | | | | | I was storing the mid of the oplock break - I should have been storing the mid from the open. There are thus 2 types of deferred packet sequence returns - ones that increment the sequence number (returns from oplock causing opens) and ones that don't (change notify returns etc). Running with signing forced on does lead to some interesting tests :-). Jeremy.
* Ensure everywhere we defer an incoming SMB request (blocking lock queue,Jeremy Allison2003-07-241-248/+250
| | | | | | | in oplock break state, change notify queue) we also push the MID onto the deferred signing queue. Tomorrow I will test this with valgrind and oplock tests. Jeremy.
