2007-10-10r12877: Stop passing structs around in smb messages, insteadJeremy Allison1-55/+133
always linearize into little-endian. 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)
2007-10-10r12713: Remove use of uint8_t -> uint8.Jeremy Allison1-1/+1

2007-10-10r12203: Add the share path into the sharemode db. This involvesJeremy Allison1-3/+3
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. (This used to be commit 9d93af713f8520ca506730dd32aa2b994937eaba)

2007-10-10r9126: Fix valgrind bug Volker found in interaction with new aio bufferJeremy Allison1-5/+7
flipping and oplocks. Jeremy. (This used to be commit a18c5ff3eada93e46da3f7cbd326b8dceb72e147)
2007-10-10r8545: Fix oplock bug introduced by oplock code "simplification" :-).Jeremy Allison1-5/+5
We *always* reply to an exclusive oplock break message even if we have no record of the oplock (and we always did before 3.0.20pre2). Jeremy. (This used to be commit b1a94aadf25e94dcc168ea3a5ae008f4e84ff296)

2007-10-10r8219: Merge the new open code from HEAD to 3.0. Haven't yet run the tortureJeremy Allison1-29/+38
tests on this as it's very late NY time (just wanted to get this work into the tree). I'll test this over the weekend.... Jerry - in looking at the difference between the two trees there seem to be some printing/ntprinting.c and registry changes we might want to examine to try keep in sync. Jeremy. (This used to be commit c7fe18761e2c753afbffd3a78abff46472a9b8eb)
2007-10-10r7963: Add aio support to 3.0.Jeremy Allison1-6/+20

(This used to be commit efea76ac71412f8622cd233912309e91b9ea52da)
2007-10-10r6172: Tidy up error processing significantly. Remove unix_ERR_XXX global ↵Jeremy Allison1-0/+3
nastyness. Jeremy. (This used to be commit d3379fe61bb934082b51a37adac232a96bafcf46)
2007-10-10r5014: Split out the request to send an async level II oplock break into aJeremy Allison1-17/+58
new function to make it clear when it's called. Remove async parameter that had been overloaded into request_oplock_break. Inspired by work from Nadav Danieli <nadavd@exanet.com>. Jeremy. (This used to be commit 05697fb50236dfc28e81f8b3900eac17cace57c1)
2007-10-10r5002: Ensure we can't remove a level II oplock without having theJeremy Allison1-17/+19
shared memory area locked. This need to be in 3.0.11. Pointed out by Nadav Danieli <nadavd@exanet.com>. Jeremy. (This used to be commit 47ed16aefbdcb6257101c6b78c93eeb7cf048185)
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)
2007-10-10r1117: Doh ! Remember to turn off signing when sending a "break to level II" ↵Jeremy Allison1-1/+9
oplock message, or we mess up the signing sequence number.... Also improve sign error reporting. Also when deferring an open that had been deferred due to an oplock break, don't re-add the mid to the pending sign queue or we increment the sequence number twice and mess up signing again... I can now bounce between 2 WinXP/Win2003 boxes opening Excel spreadsheets with signing turned on and get correct "file in use" messages. Jeremy. (This used to be commit 1745ce4e2cf7fcb4c27c077973258d157cd241b1)
2007-10-10r1089: Removed spurious oplock message in deferred open processing.Jeremy Allison1-1/+1
Fix smb signing sequence counts. Jeremy. (This used to be commit 7e2a5c36614282b6bd50b60360f443549426dd4b)
2007-10-10r1085: Now it's had some proper user testing, merge in the deferred open ↵Jeremy Allison1-1/+69
fix. I'm still doing more testing, but it fixes a behaviour that we've been wrong on ever since the start of Samba. Jeremy. (This used to be commit 894cc6d16296b934c112786eec896846156aee5d)
2003-08-07An oplock break reply from the client causes the sequence number to beJeremy Allison1-4/+0
updated by 2 if there is no open reply outstanding, else by one.... Yes - this makes no sense.... Jeremy. (This used to be commit b43ce1ff6109f6422a621329ceb713b42df40040)
2003-08-07Turns out I had my packet sequences wrong for oplock break code.Jeremy Allison1-0/+4
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. (This used to be commit 85907f02cec566502d9e4adabbd414020a26064d)
2003-08-02More fixes for client and server side signing. Ensure sequence numbersJeremy Allison1-0/+3
are updated correctly on returning an error for server trans streams. Ensure we turn off client trans streams on error. Jeremy. (This used to be commit 3a789cb7f01115c37404e5a696de363287cb0e5f)
2003-07-17Correctly toggle the signing state to what it was previosly when sendingJeremy Allison1-3/+8
an oplock break. Jeremy. (This used to be commit 9515de83a864250c417cf490b7be714c8e1e127e)

Jeremy. (This used to be commit 61fc9a7b2eafdf8cbed1f8d9aae016b828c91a08)
2003-04-22Tidyups of some dubious logic discovered whilst trying to track down aJeremy Allison1-6/+5
strange oplock related issue on the PSA. Jeremy. (This used to be commit 1dd274bf61aaaad3c475de93f53aac176678bc7c)
2003-01-30Fix for interesting resource constraint condition. When all opens areJeremy Allison1-15/+18
level 2 and a request for open with no oplock is received then the smbd should send *synchronous* break messages, not asynchronous, otherwise it spins very rapidly, releasing the lock, sending the 'break to none' messages and then re-acquiring the lock before any other process has a chance to get the lock and remove it's own oplock (at least on linux). Jeremy (This used to be commit 33e3e863eb7f35b852384e689f3272784261fc39)

mangling implementation, selectable using "mangling method = " in smb.conf It also tidies the interface a little, although it is still nasty. (This used to be commit be23d87a178e7d0691e7d942adf89bb3d2d533c2)

2002-01-31Fix from Michael Steffens <michael_steffens@hp.com> to make signalJeremy Allison1-1/+1
processing work correctly in winbindd. This is a really good patch that gives full select semantics to the Samba modified select. Jeremy. (This used to be commit 3af16ade173cac24c1ac5eff4a36b439f16ac036)
2002-01-30Removed version number from file header.Tim Potter1-2/+1

2001-09-05Fix I think for the fcntl spinning problem. Re-prioritize soJeremy Allison1-0/+14
that oplock break messages get priority over incoming client messages. Jeremy. (This used to be commit 1779f6a223dad87c3b8451d09b9808b46495a8b6)
2001-09-04Fixes to ensure invalid vuids cannot stop oplock breaks.Jeremy Allison1-5/+7
This may have bearing on the Solaris fcntl spin bug. Jeremy. (This used to be commit 0f676202529cbfead629d2c228b7d5abc2dff7d6)
2001-08-22Fixed the (incorrect) paranioa fix I put in for the fcntl lock spin.Jeremy Allison1-2/+12
Don't delete a share mode that failed to remove the oplock (doh!), just set the oplock entry to zero.... Jeremy. (This used to be commit fe4aa720181a43f7a636ca029680fab0c836b968)
2001-08-21This is Jeremy pretending to be Volker, 'cos theVolker Lendecke1-0/+13
link from Seattle is having problems. I've added 3 things here to work on the fcntl spin problem. 1). Check *all* tdb return codes... :-). 2). If we're asking ourselves to break an oplock, and we can't find a fsp pointer that matches the entry, this is a *logic bug* and we should abort and panic so someone with gdb can pick up the pieces. 3). After we've broken an oplock, ensure that the entry itself has been removed, and if not remove it ourselves. This should not be neccessary in a correctly working environmen,t, but will provide an added layer of robustness in error situations. 4). I hate german keyboards :-) :-). Jeremy. (This used to be commit 1c94fa80646f9e31377fbb41332fe4780f550cab)

2001-06-09*Wonderful* patch from Andrew Bartlett that will help ensure tdb's areJeremy Allison1-2/+4
cleaned on clients abending connections. Thanks Andrew ! Jeremy. (This used to be commit 1b3977c5367a0b713b194f369abd9872ae01ac2a)
2001-05-24Fixup the large_writex problem (a large_writex can send a full 64k of data,Jeremy Allison1-2/+2
we already have space for this we just need to understand the length correctly). Jeremy. (This used to be commit 19145bae720bbcc32dcab380c62a33d1f0e3eef0)
2001-03-11Merge of new 2.2 code into HEAD (Gerald I hate you :-) :-). Allows new SAMRJeremy Allison1-6/+0
RPC code to merge with new passdb code. Currently rpcclient doesn't compile. I'm working on it... Jeremy. (This used to be commit 0be41d5158ea4e645e93e8cd30617c038416e549)
2001-01-30Fix inspited by Alan Romeril. 50% speedup in domain logins with thisJeremy Allison1-0/+3
change to default break response time of 10ms -> 0ms. Jeremy. (This used to be commit 541c7df16fff03f98c253a46b501574cafb4469f)
2000-11-16Ok - fixed a bug in our levelII oplock code. We need to break a level II onJeremy Allison1-4/+95
a byte range lock (write lock only, but Win2k breaks on read lock also so I do the same) - if you think about why, this is obvious. Also fixed our client code to do level II oplocks, if requested, and fixed the code where we would assume the client wanted level II if it advertised itself as being level II capable - it may not want that. Jeremy. (This used to be commit 213cd0b5192307cd4b0026cae94b2f52fb1b0c02)
2000-09-27Restructuring of the code to remove dos_ChDir/dos_GetWd and re-vector themJeremy Allison1-2/+2
through the VFS. All file access/directory access code in smbd should now go via the vfs. Added vfs_chown/vfs_chmod calls. Still looking at vfs_get_nt_acl() vfs_set_nt_acl() call API design. Jeremy. (This used to be commit f96625ec124adb6e110dc54632e006b3620a962b)
