2007-10-10r17293: After the results from the cluster tests in Germany,Jeremy Allison1-2/+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)

from the client requested access mask. Jeremy. (This used to be commit 12490fafc7f98952bf709c4c504f8f2b5646f197)
2007-10-10r17140: Get rid of the lock release/reacquire code ! Turns outJeremy Allison1-85/+73
that create dispositions that cause O_TRUNC break oplocks. This simplifies the code - although we have to keep separate the client requested access mask and the access mask we actually use to open the file. Jeremy. (This used to be commit 3bcd52a4752ec6c2a8f678afa3b7b3646103ad60)
2007-10-10r17131: Optimisation - when doing a stat open don't open theJeremy Allison1-1/+1

2007-10-10r17128: Missed a logic error in my last patch. Ensure we deal with anyJeremy Allison1-5/+42
oplocks that were granted when we had released the lock. Fix strange case where stat open grants a batch oplock on file create, but grants no oplock on file open. Jeremy. (This used to be commit b7374835e6ec0c98fc4020623f0a37c0c173b8aa)
2007-10-10r17125: Drastic problems require drastic solutions. There'sJeremy Allison1-76/+73
no way to get all the cases where kernel oplocks are on and we can't open the file and get the correct semantics (think about the open with truncate with an attribute only open - we'd need a vfs change to add the truncate(fname, len) call). So always drop the share mode lock before doing any real fd opens and then re-acquire it afterwards. We're already dealing with the race in the create case, and we deal with any other races in the same way. Volker, please examine *carefully* :-). This should fix the problems people reported with kernel oplocks being on. Jeremy. (This used to be commit 8171c4c404e9f382880c65daa0232f89e560f399)

2007-10-10r15958: Make us pass RAW-OPLOCK with kernel oplocks off.Jeremy Allison1-13/+20
This allows a requestor to set FORCE_OPLOCK_BREAK_TO_NONE to ensure we don't break to level 2. Fixed a couple of resource leaks in error paths in open_file_ntcreatex. Jeremy. (This used to be commit c7c9adcce7f13d01445f31b07fb28a76f0a1d6df)
2007-10-10r15949: Patch for bug #3308 to stop us returning duplicateJeremy Allison1-5/+8
mid replies on path based set-eof trans2 calls. Needs modification for HEAD (as in head open_file_ntcreateX properly returns NTSTATUS - I'll fix this tomorrow my time). Secondly it still fails the Samba4 RAW-OPLOCK smbtorture because of an interesting case. Our oplock code always returns "break to level 2" if it can. In this case (path-based set-eof or set-allocation size on an exclusive oplocked file) W2K3 always sends a break-to-none. We send the break to none (from level2) after we've done the write for eof or allocation size. I need to work out some way of telling our break code to always break to none (might need to extend the message field). Jeremy. (This used to be commit ad9895c654f400e242adcd4099f7cd004521ee92)

2007-10-10r15293: Don't ever set O_SYNC on open unless "strict sync = yes".Jeremy Allison1-1/+1
This could be the cause of the perf. problem reported between 3.0.14a and 3.0.2x. Lufthansa has *wireless* on their flights to the USA now... (I'm in heaven ! :-). Jeremy. (This used to be commit dbc03125f2643f8ecff8e901cb23fa6408cce011)
2007-10-10r15138: Teach Samba the difference between exclusive and batch oplocks.Jeremy Allison1-40/+60
Pass Samba4 oplock test (with kernel oplocks off). Jeremy. (This used to be commit 3c260bcce2de76d724279e07dca61eadddfb8782)
2007-10-10r14898: This change is an attempt to improve the quality of the information thatJames Peach1-2/+2
is produced when a process exits abnormally. First, we coalesce the core dumping code so that we greatly improve our odds of being able to produce a core file, even in the case of a memory fault. I've removed duplicates of dump_core() and split it in two to reduce the amount of work needed to actually do the dump. Second, we refactor the exit_server code path to always log an explanation and a stack trace. My goal is to always produce enough log information for us to be able to explain any server exit, though there is a risk that this could produce too much log information on a flaky network. Finally, smbcontrol has gained a smbd fault injection operation to test the changes above. This is only enabled for developer builds. (This used to be commit 56bc02d64498eb3faf89f0c5452b9299daea8e95)

2007-10-10r14602: Fix another logic bug in new oplock handling. JustJeremy Allison1-12/+17
because lck->num_share_modes != 0 doesn't mean that there *are* other valid share modes. They may be all marked "UNUSED" or be deferred open entries. In that case don't downgrade the granted oplock to level2 needlessly - a client can have an exclusive oplock in this case. The original code handled this correctly in the lck->num_share_modes == 0 case but not in the case where there were no valid share modes but lck->num_share_modes != 0. I'll clean up my Samba4 torture tester for this and commit it tomorrow. Jeremy. (This used to be commit 306061c93d9181262298516fefd83444f5a65ce5)
2007-10-10r14596: Fix a logic bug with multiple oplock contention.Jeremy Allison1-18/+33
The sad thing is the core of this bug fix is just removing a paranoia "exit_server" call, as the rest of the logic was already correct :-). Lots of comments to explain the logic added. I will look at adding tests to exercise this, might be possible. Jeremy. (This used to be commit c2488db727e1a00f112be7b169de9e6208e311f3)

2007-10-10r13314: This code has been causing problems since 1.9.x I think.Jeremy Allison1-19/+0
Remove check_for_pipe() - Volker was completely correct. If it gets re-added it will be in a old open call path, not in the generic code path. Jeremy. (This used to be commit 50c894a6e949d4d3579926650674f381a821a671)

honored (ie. the file gets deleted) for derectories when set at open time - even though it doesn't show in the qfileinfo call. This is not true of files.... (if anyone from the EU is listening, it's stuff like this that makes CIFS non-documentable :-). Jeremy. (This used to be commit e2fc8a196a06f76aa47fabc30872c701a2f7ccec)
2007-10-10r13293: Rather a big patch I'm afraid, but this should fix bug #3347Jeremy Allison1-0/+2
by saving the UNIX token used to set a delete on close flag, and using it when doing the delete. libsmbsharemodes.so still needs updating to cope with this change. Samba4 torture tests to follow. Jeremy. (This used to be commit 23f16cbc2e8cde97c486831e26bcafd4ab4a9654)
2007-10-10r13274: Fix for bug #3467. Not a show stopper.Jeremy Allison1-24/+22

Should fix all Solaris issues with this, plus provide a cleaner base moving forward for cluster-aware Samba where smbd's can communicate across different compilers/architectures (eventually these message will have to go cross-machine). Jeremy. (This used to be commit d01824b78576a034428e1cef73868d1169057991)

2007-10-10r12721: GPFS 2.4 on Linux will contain some windows semantics, ie share ↵Volker Lendecke1-0/+14
modes and oplocks across the cluster. Adapt Samba to it. The gpfs API is called via libgpfs.so. This code is written with dlopen(), so that you can compile on a system with gpfs installed and later on run on systems without gpfs available. So to actually make Samba call gpfs share mode calls you need to compile with gpfs.h and libgpfs.so around and set 'gpfs share = yes' on the shares you export from GPFS.

2007-10-10r12203: Add the share path into the sharemode db. This involvesJeremy Allison1-5/+10
revving the minor version number for libsmbsharemodes (we now have a new _ex interface that takes the share path as well as the filename). Needed for #3303. Some code written by SATOH Fumiyasu <fumiya@samba.gr.jp> included in the changes to locking/locking.c. The smbstatus output is a bit of a mess and needs overhauling... Jeremy.

<alex@infobit.ru>. A fcbopen specific part of the code was erroneously being called as part of the mainline open. Note, that this patch superceeds and replaces the fix that Volker added for this bug (which he added a Samba4 torture test for ) : "Fix a race condition in Samba 3. If two files are opened simultaneously with NTCREATEX_DISP_CREATE (create if not exists, else fail) they might end up with two or more times NT_STATUS_OK as EEXIST is not correctly handled." Jeremy.
