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.

2008-01-05Fix %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)

2007-10-10r24163: 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)

2007-10-10r23997: 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)

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)

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.

2007-10-10r20237: Replace exit_server with exit_server_cleanly where appropriate. AllJames Peach1-3/+3
send_smb failures should be clean exits. All times when we exit as a matter of policy should also be clean exits. (This used to be commit d6382092e72120a3c89ffe81975e8898d454bf06)

2007-10-10r17541: When returning a trans2 request, if the "max dataJeremy Allison1-1/+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.

2007-10-10r17314: Optimisation for POSIX locking. If we're downgradingJeremy Allison1-1/+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. (This used to be commit a7a0b6ba50f4cf7c5a0a29809fdff9e1266a29e7)
2007-10-10r17293: After the results from the cluster tests in Germany,Jeremy Allison1-3/+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. (This used to be commit 4ace291278d9a44f5c577bdd3b282c1231e543df)
2007-10-10r17105: Fix the race Volker found - we had a non-lockedJeremy Allison1-197/+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. (This used to be commit b81d6d1ae95a3d3e449dde629884b565eac289d9)
2007-10-10r17098: Samba3 now cleanly passes Samba4 RAW-LOCK tortureJeremy Allison1-38/+166
test. Phew - that was painful :-). But what it means is that we now implement lock cancels and I can add lock cancels into POSIX lock handling which will fix the fast/slow system call issue with cifsfs ! Jeremy. (This used to be commit f1a9cf075b87c76c032d19da0168424c90f6cb3c)
