Bottleneck with Winbind and NT ACLs in 2.2.7a
Hi,
we are running a big Samba 2.2.7a server with Winbind (100 concurrent
users, 600 id mappings created since then) since last weekend.
It's running quite well! :)
However, users are complaining about Samba being very slow when
NT ACL support is enabled. I'm suspecting that winbindd is the
bottleneck.
In winbindd's log I can see that it has to serve [ug]id to sid
requests at a very high frequency. Most of them seem to be triggered
by smbd daemons working on POSIX ACLs, and the UIDs and GIDs
requested are almost always those of the user running a session.
Requests are keeping winbindd busy all the time. And when winbindd
is busy talking to DCs, user sessions have to wait for ACL settings
to complete.
As the ID mappings are static - as soon as they exist - wouldn't it
be a good idea to have smbd cache those it has come across in the
current session?
In the attached patch I have tried to implement such a local
mapping cache for smbd. What do you think about it?
Cheers!
Michael

RE: A Union of two directories
Nice description Simo. It caused me to think. I can see two cases for the use of such a union. The first is where the user wants to make a foreground overlay which they can edit, where files are made read-write by copying from the background to the foreground. This appears the same as a normal file system until the background share is unmounted. Then, the skeleton of the tree and the user's edited files are all that remains. Unless such a system is used under the control of a tool such as ClearCase, I don't see what utility it would have in the general market. (Consider the merges, or the fact that the changes would always be separate. Neither case is both common and simple.) Perhaps there are software engineering applications. It would take a software engineer to operate it. ;) The second case is where Simo's option background write_over is turned off. This effectively puts the background in the foreground, and prevents writing. The user's read-write underlay then occupies any file namespace not covered by the read-only overlay. This would be useful for system directories such as network storage areas that contain organization-wide applications. It would be mounted on the user's Program Files folder, for example. Mounting their personal applications folder in the same place would cause their own applications to appear to be installed side-by-side with the shared ones. Any conflict would cause the read-only system version of the file to show through. Writing a file into the combined folders would only be allowed if the file doesn't already exist, or if it only exists in the personal folder. This configuration would appeal to system administrators, who want to make sure the users have access to centrally maintained applications, without giving the users the ability to alter the applications. Opposite to the above, the user may want to be able to overlay their personal folder on the shared one. Going back to the Program Files example, this would allow one user to install an updated version of an application over an older version of the same application in the shared folder. This configuration would be useful in supporting a super-user who takes responsibility for maintaining their own applications, who wants to take advantage of the default installations. Given my assumption that dir1 and dir2 (dir3? dir4?) are keywords which can be used to determine the background-to-foreground order of the overlay, and the inclusion of the read-only read-write controls which are already available, the latter two configurations can be accomplished. Perhaps a better way would be to introduce a meta-share, which names a number of other shares, the order in which they should be overlaid, and their write status. Other normal share keywords controlling user access could also be applied. Here is an example of the second configuration described above: [accounting_apps] path=/storage/shared public = yes writable = no guest ok = yes [john_doe_personal_apps] path=/storage/home/john_doe/apps public = no writable = yes guest ok = no valid users = @CENTRAL+John Doe write list = @CENTRAL+John Doe [john_doe_apps] meta share = accounting_apps, john_doe_personal_apps write control = no, yes public = no valid users = @CENTRAL+John Doe write list = @CENTRAL+John Doe Note that shares named to the left in the meta share keyword are in the foreground. The write control keyword arguments refer by order to the shares named in the meta share keyword. By changing the order of the meta share and the write control arguments, this configuration becomes the super-user example. In my opinion, this would be useful. As was said earlier, this all belongs in a VFS layer. -Original Message- From: Simo Sorce [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 04, 2003 4:38 AM To: David Lee Cc: Stefan (metze) Metzmacher; '[EMAIL PROTECTED]' Subject: Re: A Union of two directories On Tue, 2003-02-04 at 11:03, David Lee wrote: On Tue, 4 Feb 2003, Stefan (metze) Metzmacher wrote: It would be fine to have config options for match witch files should be taken from with directory. something like this: dir1 path = /home/samba dir1 mode = readonly dir1 files = *.c,*.h,configure,Makefile dir1 exclude files = *.o dir2 path = /home/%m/samba dir2 mode = write dir2 files = *.o dir2 exclude files = *.c,*.h and something simular for directories I think the easiest thing is to have a background common read-only directory only few parameter needed: background path = /home/common background write_over = yes|no all the files present here will be seen as read-only by everyone. if you open the file read-write you may choose to either fail the open or copy over the file to the user directory and use that file instead.

OTOH, I haven't used 2.4.20 yet for this environment. As I wrote earlier I also can't believe it's a filesystem issue. When you say you compiled with large file support, does that mean you made changes to the build scripts? Samba should already build with LFS support on Linux 2.4. Yup, I had to change the build scripts. If I remember correctly the Debian package comes with shrink-wrapped configure.cache files so that they would always overwrite certain changes I made to the configure statement inside debian/rules. I think that there was a already a bug filed against the non-support of large files. The poster of this bug report also mentioned that you had to recompile it in order to get LFS. OTOH everything I just wrote could be wrong. I'm currently working on a multitude of building areas so I could confuse something with something totally different. :-) -- L I N U X .~.

Debian configure problems
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi! Probably this is more of a debian than a Samba problem. To compile Samba 2_2 CVS of today with acl support und Debian 3.0, I not only had to apt-get acl-dev but also attr-dev. For me it was not possible to compile acl-aware programs with -lacl due to link errors: vlendec@delphin:~$ gcc -lacl aclt.c /usr/lib/libacl.so: undefined reference to `fgetxattr' /usr/lib/libacl.so: undefined reference to `removexattr' /usr/lib/libacl.so: undefined reference to `setxattr' /usr/lib/libacl.so: undefined reference to `fsetxattr' /usr/lib/libacl.so: undefined reference to `getxattr' collect2: ld returned 1 exit status Installing attr-dev and adding -lattr fixed this. So, to me it seems that acl-dev should have a dependency on attr-dev. The Samba configure program only adds -lacl to the configure test. I explicitly had to say LIBS=-lattr ./configure ... to make it detect posix acl support properly. My problem now is: Where do I report this correctly???

Re: Bottleneck with Winbind and NT ACLs in 2.2.7a
On Tue, Feb 04, 2003 at 02:12:29PM +0100, Michael Steffens wrote: Hi, we are running a big Samba 2.2.7a server with Winbind (100 concurrent users, 600 id mappings created since then) since last weekend. It's running quite well! :) However, users are complaining about Samba being very slow when NT ACL support is enabled. I'm suspecting that winbindd is the bottleneck. In winbindd's log I can see that it has to serve [ug]id to sid requests at a very high frequency. Most of them seem to be triggered by smbd daemons working on POSIX ACLs, and the UIDs and GIDs requested are almost always those of the user running a session. Requests are keeping winbindd busy all the time. And when winbindd is busy talking to DCs, user sessions have to wait for ACL settings to complete. As the ID mappings are static - as soon as they exist - wouldn't it be a good idea to have smbd cache those it has come across in the current session? In the attached patch I have tried to implement such a local mapping cache for smbd. What do you think about it? Damn good idea ! I think I'll look into applying some version of this - thanks !

Re: [Samba] deleting symlinks only
The problem is not in teaching samba anything. When you delete a directory in windows explorer it doesn't just send a command to delete the directory. It recurses down the directory and first sends commands to delete each individual file and then sends a command to delete the directory. Samba has no way of knowing when it starts getting these delete commands that the user is trying to delete the upper directory until all the files have already been deleted. Antonio Nikolic wrote: So: Is there not a way, to teach samba (maybe in a future-release) to first check on recieving a deletion request whether or not a directory possibly is a link and delete the link only?

Wella fter removing the cmd file all was well - until lately when now we get an empty directory - only trouble is that I know I have 922 files in it. is there a magic number that stops samba from displaying files?

Re: Solaris fcntl CPU/Lock update
Hello all,
Andrew, true GDB is thread aware but I think last time I used

aware!
I found the following if it can help us debug this thing

There exists under Solaris a usleep in libthread.so !!!
Of course, as well in libc.so.
From libc.so :

This here :

Re: Solaris fcntl CPU/Lock update
Jeff, Ok, you're using nss_ldap from PDAL to use /etc/nsswitch.conf like passwd: ldap files (or reverse) group: ldap files etc Right? (From what I recall that's what nss_ldap is used for). If you did not compile with Samba, it means that if you do ldd on smbd it should not print libthread or libpthread. Is this the result you get? If this is the result you get -- than I REALLY don't understand how smbd process opens libthread and libpthread! I get this @ home from 2.2.pre-8 (I CVS sync everyday every once and a while). libsec.so.1 = /usr/lib/libsec.so.1 libgen.so.1 = /usr/lib/libgen.so.1 libsocket.so.1 =/usr/lib/libsocket.so.1 libnsl.so.1 = /usr/lib/libnsl.so.1 libdl.so.1 =/usr/lib/libdl.so.1 libpam.so.1 = /usr/lib/libpam.so.1 libsendfile.so.1 = /usr/lib/libsendfile.so.1 libc.so.1 = /usr/lib/libc.so.1 libmp.so.2 =/usr/lib/libmp.so.2 /usr/platform/SUNW,Ultra-2/lib/libc_psr.so.1 If you don't have this problem on the other box, it can be a Solaris bug introduced lately. The binaries you run on both boxes don't differ, right? They are the same exact copy? Pierre B.
