to work (not a lot of testing yet though).
Now we just need to deal with people worried about having more than
two nmbd processes sometimes. (the async processes are created on
demand for browse sync, so you'll only see more than 2 occasionally)
(This used to be commit a350a54680e4170e2adf571b010ea508e7291780)
are now sorted by the number of common leading bits in the IP address
with the address of the querying host.
(This used to be commit 4460a1bc6aa7666d1c71d32ba73855d6ed32320a)
It now has a line like this:
VERSION 1 251152
the first number is a version #define in nmbd_winsserver.c and will be
used if we ever have to change the format again.
The second number is a hash of the current interfaces setting. It is
used to detect the case where nmbd is restarted on a machine after the
IP of the machine has changed (or the interfaces list has changed in
any way). When that happens we need to discard the old wins.dat cache
or you end up with chaos. This has bitten quite a few people, they
find that when they move a machine it continues using the old IP for
some things for the next week until the wins entries time out!
I've checked, and the old nmbd can handle the new format, although it
does spit out a spurious error message about the VERSION line. So
users can safely run 2.0alpha then switch back to 1.9.18 without
problems.
(This used to be commit c4a8cdc60a5b01894ab2456e77b6d89d4c16a088)
to account for padding/alignment issues. Eventually I'd like to find a
way to get rid of this construct altogether as it is a bit error
prone and hard to debug.
also added a new macro:
ZERO_STRUCTP() that takes a pointer to a structure and zeros the
structure. Used in nmbd to zero allocated structures before freeing
them to try to catch bugs a bit faster.
(This used to be commit d3dda65d5177154e2128f50ca3dd34e8e13b6b08)
correctly. Added new parameter "stat cache size" - set to 50 by default.
I now declare the statcache code officially "open" for business :-).
It gets a hit rate of 97% with a NetBench run and seems to make
using a case insensitive run as efficient as a case sensitive run.
Also tidied up our sys_select usage - added a maxfd parameter and
also added an implementation of select in terms of poll(), for systems
where poll() is much faster. This is disabled by default.
Jeremy.
(This used to be commit 779b924ec1f6c81ff578d22295b20fece698d1fc)
NetBench testing though.... :-). Attempts to efficiently reduce
the number of stat() calls Samba does.
Jeremy.
(This used to be commit d0e48a2d8072c3e77a57ac6a2fb5044c05f03b41)
the head of an SMB request (ie. are part of a chain) will not be queued -
this will be fixed when we move to the new chain code. In practice, this
doesn't seem to cause much of a problem (in my admittedly limited testing)
bug a debug level zero message will be placed in the log when this
happens to help determine how real the problem is.
smbd/locking.c: New debug messages.
smbd/blocking.c: New blocking code - handles SMBlock, SMBlockread and SMBlockingX
smbd/chgpasswd.c: Fix for master fd leak.
smbd/files.c: Tidyup comment.
smbd/nttrans.c: Added fnum to debug message.
smbd/process.c: Made chain_reply() use construct_reply_common(). Added blocking
lock queue processing into idle loop.
smbd/reply.c: Added queue pushes for SMBlock, SMBlockread and SMBlockingX.
Jeremy.
(This used to be commit e1dd03ecda0bc6d7eaa31070c83774bb5679fd1b)
include/includes.h: Added nterr.h.
locking/locking.c: Moved blocking lock code into smbd/blocking.c for link purposes.
smbd/close.c: Added blocking lock removal to file close.
smbd/filename.c: Tidied up unix_convert() so I could read it (:-) in preparation
for the stat_cache code.
smbd/nttrans.c: Added WRITE_ATTRIBUTES check.
smbd/reply.c: Fixed multibyte char problem in wildcard mask.
Jeremy.
(This used to be commit 148eaba3dadb1d0bd3ac3ef53da3d9811636e89a)
the splitup was done with an axe, not a scalpel, so there are some
rough edges. I mostly wanted to get the general form right with fine
tuning of what goes where to come later. Still, this is better than
what we had before where server.c was a general repository for
anything that didn't fit elsewhere.
(This used to be commit a6d194886a4a5f7507fa37289ff96c1be56f14a6)
server.c without breaking things.
this splits off netprot.c and fileio.c for negprot and read/write/seek
handling respectively.
(This used to be commit b3d7014643ec9f2eef6e6f598f5b9db1fe2f930d)
the chain pointer is now stored as a static and is set whenever a
handle is created or extracted. This also makes the code less error
prone.
(This used to be commit 068a862982bea726e8d7b1b4065d510b9840a272)
removed most cases where a pnum is used and substituted a pipes_struct*.
in files.c I added a offset of 0x1000 to all file handles on the
wire. This makes it much less likely that bad parsing will give us the
wrong field.
(This used to be commit 8bc2627ff28d340db65bfa017daca2dc291d5ef7)
private to files.c)
It now is a doubly linked list with a bitmap for allocated file
numbers. Similarly for the fd_ptr code. I also changed the default
maximum number of open files to 4096. The static cost is 1 bit per
file.
It all seems to work, and it passes the "does Sue scream" test, but if
you see weird behaviour then please investigate. With the volume of
new code that has gone in there are bound to be one or two bugs
lurking.
note that you must do a "make clean" before building this as many data
structures have changed in size.
(This used to be commit 79755ce97004b787d7e83a8d18fc4c7c003b7231)
bitmap.c: added bitmap hanlding code in preparation for increasing the
default max open files to several thousand
(This used to be commit f573a65b67e7a57586fec57845598e49b157ee0a)
in files.c
it should now be faily easy to expand the default MAX_OPEN_FILES to
many thousands.
(This used to be commit b088c804f98908eb02f05ab2f2e8a61691a0a582)
Connections[] is now a local array in server.c
I might have broken something with this change. In particular the
oplock code is suspect and some .dll files aren't being oplocked when
I expected them to be. I'll look at it after I've got some sleep.
(This used to be commit c7ee025ead4a85b6fa44a832047b878451845fb6)
locking/locking.c: Made #ifdef'ed out functions static for Make proto.
lib/util.c: Re-instated old mask_match code for UNIX filesystem checks
only. Client calls use the new mask_match code. Changed the
name of the old function to unix_mask_match.
Jeremy.
(This used to be commit b68e756ff57622c6c74f28031d4be964d7b1c9bc)
modified it not to need any smbd specific structures and instead pass
things from smbd.
(This used to be commit 162141d3b3fcf53fbc6a1f18702df85c2b7f1781)
illogical places. Once I get everything compiled these will need to be
revisited, but at least the new Makefile.in makes it really obvious
what is out of place.
(This used to be commit beef5341fc313249bf1117deccb9c21c510c4697)
for changes in the directory modify timestamps. A better version
will look at the requested client flags, and create a hash that
represents the current state of the directory, and check against
this instead.
debug.c: Added lp_timestamp_logs() function.
loadparm.c: Added "change notify timeout" in seconds (default 60)
- this is the scan rate for a directory.
Added ""timestamp logs" boolean - default True. Turns
off log timestamps (so I can read them :-).
nttrans.c: ChangeNotify implementation.
server.c: ChangeNotify implementation.
shmem_sysv.c: Added exits on shmem errors (without them smbd can
core dump if some calls fail).
smb.h: Added ChangeNotify flags for future use.
util.c: Tidied up typedef.
Jeremy.
(This used to be commit a0748c3f53974483680ebe2ea4f556ece8d7fa43)
Makefile.in: I've added debug.o.
proto.h : Rebuilt, as is standard for these sorts of things.
smb.h : New macros, etc.
util.c : Debug code removed.
I'll check in debug.c in the next step.
Chris -)-----

trans2.c: Changes to implement union in files_struct.
smb.h: Changes to implement union in files_struct.
util.c: Changed linked list code to UNIQX linked list. This will make
the other lists I need to implement for ChangeNotify and blocking
locks easier.
Jeremy.
(This used to be commit 3a5eea850bb256b39cff8ace1e4fb4e0c1f5472b)
time test instead. This also allows us to get rid of the igroups
element of a couple of structures.
(This used to be commit 8b25fe734166b76ceebf8d9543c706ebe0fddc96)
reply.c: Do the same mask expansion we do in trans2.c - needed for Win98.
trans2.c: Make the mask expansion into a function call now we have to
do it twice.
Jeremy.
(This used to be commit 7b3a9d6285cc0d1967155a68845e28c6296ecc67)
locking.c: Added code to deal with real open mode of file.
reply.c: Added strict sync parameter.
server.c: Added strict sync parameter. Fixed open modes.
Jeremy.
(This used to be commit ed57b603b5c9333d588e62d774ad2be67e43ffd9)
local.h: Kept FSTYPE_STRING as Samba for now.
nmbd_browsesync.c: Added bugfix from Matt Chapman mattyc@cyberdude.com
- lmb_browserlist is now a struct ubi_dlList not a
struct browse_cache_record *.
server.c:
smb.h:
uid.c:
password.c: Removed attrs code - it is not used anywhere.
Jeremy
(This used to be commit ef1af7fe6d5c58ae57b8e4efff0729e1a315da43)
as the code in reply_lockingX wasn't taking account of
the difference between read and write locks ! How did this
ever work :-) !
reply.c:
server.c: Add lock type to is_locked() and do_lock().
util.c: Also added code from klausr@ITAP.Physik.Uni-Stuttgart.De
to fix problem with log files growing too large if an
smbd writes less than 100 debug messages.
Jeremy.
(This used to be commit 80080abf772a470d5f0f4dcd4a75fb2a09a9fb2a)
local.h: Changed MAXDIR to MAX_OPEN_DIRECTORIES - shmem size also tuned by this.
dir.c: Use MAX_OPEN_DIRECTORIES.
nttrans.c: Allow opening of a directory to succeed. Doesn't actually open
a file descriptor but takes a files_struct slot marked as an
fd.
reply.c: Changed to close any outstanding is_directory files.
reply_close changed to understand directory files.
server.c: Added open_directory(), close_directory() calls.
smb.h: Added is_directory to files_struct.
Changed OPEN_FNUM to check that target is !is_directory (this
prevents the normal file calls from processing a directory
files_struct.
Jeremy.
(This used to be commit e01ce693f47e75e277f3440d46e32b0bd866b550)

smb.h: Updated NT SMB #defines.
Jeremy.
(This used to be commit 3e5cada9885059e9926eb6a56d350c4b1b53d245)
ipc.c:
loadparm.c:
printing.c:
Added code from <Dirk.DeWachter@rug.ac.be> to implement print
queue pausing. New parameters are "queuepause command" and
"queueresume command".
util.c: Added fix for mount options in autmount map.
lib/rpc/include/rpc_misc.h: Removed duplicate pipe names for Jean-Francois.
Jeremy.
(This used to be commit 559a9bf2bbdeae3e76ba9178779cd3a9537c4e91)
mem_dup() allocates the required memory before copying the
source data. It returns NULL if memory could not be allcoated,
else a pointer to the newly allocated memory.
proto.h: Rebuilt to add the prototype for mem_dup().
(This used to be commit 7f7e265ab457d046441d502d4b8447bc2c966675)

externally from the NT transact rename.
server.c: Changed stat calls to sys_stat - found in code review
of bugfix.
Jeremy.
