The Samba Team has tried to come up with a model which is +the best possible compromise between elegance, portability, security +and the constraints imposed by the very messy SMB and CIFS +protocol. </P +><P +>It also tries to answer some of the frequently asked questions such as:</P +><P +></P +><OL +TYPE="1" +><LI +><P +> Is Samba secure when running on Unix? The xyz platform? + What about the root priveliges issue?</P +></LI +><LI +><P +>Pros and cons of multithreading in various parts of Samba</P +></LI +><LI +><P +>Why not have a separate process for name resolution, WINS, and browsing?</P +></LI +></OL +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN65">Multithreading and Samba</H2 +><P +>People sometimes tout threads as a uniformly good thing. They are very +nice in their place but are quite inappropriate for smbd. nmbd is +another matter, and multi-threading it would be very nice. </P +><P +>The short version is that smbd is not multithreaded, and alternative +servers that take this approach under Unix (such as Syntax, at the +time of writing) suffer tremendous performance penalties and are less +robust. nmbd is not threaded either, but this is because it is not +possible to do it while keeping code consistent and portable across 35 +or more platforms. (This drawback also applies to threading smbd.)</P +><P +>The longer versions is that there are very good reasons for not making +smbd multi-threaded. Multi-threading would actually make Samba much +slower, less scalable, less portable and much less robust. The fact +that we use a separate process for each connection is one of Samba's +biggest advantages.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN70">Threading smbd</H2 +><P +>A few problems that would arise from a threaded smbd are:</P +><P +></P +><OL +TYPE="1" +><LI +><P +> It's not only to create threads instead of processes, but you + must care about all variables if they have to be thread specific + (currently they would be global).</P +></LI +><LI +><P +> if one thread dies (eg. a seg fault) then all threads die. We can + immediately throw robustness out the window.</P +></LI +><LI +><P +> many of the system calls we make are blocking. Non-blocking + equivalents of many calls are either not available or are awkward (and + slow) to use. So while we block in one thread all clients are + waiting. Imagine if one share is a slow NFS filesystem and the others + are fast, we will end up slowing all clients to the speed of NFS.</P +></LI +><LI +><P +> you can't run as a different uid in different threads. This means + we would have to switch uid/gid on _every_ SMB packet. It would be + horrendously slow.</P +></LI +><LI +><P +> the per process file descriptor limit would mean that we could only + support a limited number of clients.</P +></LI +><LI +><P +> we couldn't use the system locking calls as the locking context of + fcntl() is a process, not a thread.</P +></LI +></OL +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN86">Threading nmbd</H2 +><P +>This would be ideal, but gets sunk by portability requirements.</P +><P +>Andrew tried to write a test threads library for nmbd that used only +ansi-C constructs (using setjmp and longjmp). Unfortunately some OSes +defeat this by restricting longjmp to calling addresses that are +shallower than the current address on the stack (apparently AIX does +this). This makes a truly portable threads library impossible. So to +support all our current platforms we would have to code nmbd both with +and without threads, and as the real aim of threads is to make the +code clearer we would not have gained anything. (it is a myth that +threads make things faster. threading is like recursion, it can make +things clear but the same thing can always be done faster by some +other method)</P +><P +>Chris tried to spec out a general design that would abstract threading +vs separate processes (vs other methods?) and make them accessible +through some general API. This doesn't work because of the data +sharing requirements of the protocol (packets in the future depending +on packets now, etc.) At least, the code would work but would be very +clumsy, and besides the fork() type model would never work on Unix. (Is there an OS that it would work on, for nmbd?)</P +><P +>A fork() is cheap, but not nearly cheap enough to do on every UDP +packet that arrives. Having a pool of processes is possible but is +nasty to program cleanly due to the enormous amount of shared data (in +complex structures) between the processes. We can't rely on each +platform having a shared memory system.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN92">nbmd Design</H2 +><P +>Originally Andrew used recursion to simulate a multi-threaded +environment, which use the stack enormously and made for really +confusing debugging sessions. Luke Leighton rewrote it to use a +queuing system that keeps state information on each packet. The +first version used a single structure which was used by all the +pending states. As the initialisation of this structure was +done by adding arguments, as the functionality developed, it got +pretty messy. So, it was replaced with a higher-order function +and a pointer to a user-defined memory block. This suddenly +made things much simpler: large numbers of functions could be +made static, and modularised. This is the same principle as used +in NT's kernel, and achieves the same effect as threads, but in +a single process.</P +><P +>Then Jeremy rewrote nmbd. The packet data in nmbd isn't what's on the +wire. It's a nice format that is very amenable to processing but still +keeps the idea of a distinct packet. See "struct packet_struct" in +nameserv.h. It has all the detail but none of the on-the-wire +mess. This makes it ideal for using in disk or memory-based databases +for browsing and WINS support. </P +></DIV +></DIV +><DIV +CLASS="CHAPTER" +><HR><H1 +><A +NAME="DEBUG">The samba DEBUG system</H1 +><DIV +CLASS="SECT1" +><H2 +CLASS="SECT1" +><A +NAME="AEN103">New Output Syntax</H2 +><P +> The syntax of a debugging log file is represented as:</P +><P +><TABLE +BORDER="0" +BGCOLOR="#E0E0E0" +WIDTH="100%" +><TR +><TD +><PRE +CLASS="PROGRAMLISTING" +> >debugfile< :== { >debugmsg< } + + >debugmsg< :== >debughdr< '\n' >debugtext< + + >debughdr< :== '[' TIME ',' LEVEL ']' FILE ':' [FUNCTION] '(' LINE ')' + + >debugtext< :== { >debugline< } + + >debugline< :== TEXT '\n'</PRE +></TD +></TR +></TABLE +></P +><P +>TEXT is a string of characters excluding the newline character.</P +><P +>LEVEL is the DEBUG level of the message (an integer in the range + 0..10).</P +><P +>TIME is a timestamp.</P +><P +>FILE is the name of the file from which the debug message was +generated.</P +><P +>FUNCTION is the function from which the debug message was generated.</P +><P +>LINE is the line number of the debug statement that generated the +message.</P +><P +>Basically, what that all means is:</P +><P +></P +><OL +TYPE="1" +><LI +><P +>A debugging log file is made up of debug messages.</P +></LI +><LI +><P +>Each debug message is made up of a header and text.

They may help people who are looking at unix<->PC +interoperability.</P +><P +>It was written to help out a person who was writing a paper on unix to +PC connectivity.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN544">Usernames</H2 +><P +>The SMB protocol has only a loose username concept. Early SMB +protocols (such as CORE and COREPLUS) have no username concept at +all. Even in later protocols clients often attempt operations +(particularly printer operations) without first validating a username +on the server.</P +><P +>Unix security is based around username/password pairs. A unix box +should not allow clients to do any substantive operation without some +sort of validation. </P +><P +>The problem mostly manifests itself when the unix server is in "share +level" security mode. This is the default mode as the alternative +"user level" security mode usually forces a client to connect to the +server as the same user for each connected share, which is +inconvenient in many sites.</P +><P +>In "share level" security the client normally gives a username in the +"session setup" protocol, but does not supply an accompanying +password. The client then connects to resources using the "tree +connect" protocol, and supplies a password. The problem is that the +user on the PC types the username and the password in different +contexts, unaware that they need to go together to give access to the +server. The username is normally the one the user typed in when they +"logged onto" the PC (this assumes Windows for Workgroups). The +password is the one they chose when connecting to the disk or printer.</P +><P +>The user often chooses a totally different username for their login as +for the drive connection. Often they also want to access different +drives as different usernames. The unix server needs some way of +divining the correct username to combine with each password.</P +><P +>Samba tries to avoid this problem using several methods. These succeed +in the vast majority of cases. The methods include username maps, the +service%user syntax, the saving of session setup usernames for later +validation and the derivation of the username from the service name +(either directly or via the user= option).</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN552">File Ownership</H2 +><P +>The commonly used SMB protocols have no way of saying "you can't do +that because you don't own the file". They have, in fact, no concept +of file ownership at all.</P +><P +>This brings up all sorts of interesting problems. For example, when +you copy a file to a unix drive, and the file is world writeable but +owned by another user the file will transfer correctly but will +receive the wrong date. This is because the utime() call under unix +only succeeds for the owner of the file, or root, even if the file is +world writeable. For security reasons Samba does all file operations +as the validated user, not root, so the utime() fails. This can stuff +up shared development diectories as programs like "make" will not get +file time comparisons right.</P +><P +>There are several possible solutions to this problem, including +username mapping, and forcing a specific username for particular +shares.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN557">Passwords</H2 +><P +>Many SMB clients uppercase passwords before sending them. I have no +idea why they do this. Interestingly WfWg uppercases the password only +if the server is running a protocol greater than COREPLUS, so +obviously it isn't just the data entry routines that are to blame.</P +><P +>Unix passwords are case sensitive. So if users use mixed case +passwords they are in trouble.</P +><P +>Samba can try to cope with this by either using the "password level" +option which causes Samba to try the offered password with up to the +specified number of case changes, or by using the "password server" +option which allows Samba to do its validation via another machine +(typically a WinNT server).</P +><P +>Samba supports the password encryption method used by SMB +clients. Note that the use of password encryption in Microsoft +networking leads to password hashes that are "plain text equivalent". +This means that it is *VERY* important to ensure that the Samba +smbpasswd file containing these password hashes is only readable +by the root user. See the documentation ENCRYPTION.txt for more +details.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN563">Locking</H2 +><P +>The locking calls available under a DOS/Windows environment are much +richer than those available in unix. This means a unix server (like +Samba) choosing to use the standard fcntl() based unix locking calls +to implement SMB locking has to improvise a bit.</P +><P +>One major problem is that dos locks can be in a 32 bit (unsigned) +range. Unix locking calls are 32 bits, but are signed, giving only a 31 +bit range. Unfortunately OLE2 clients use the top bit to select a +locking range used for OLE semaphores.</P +><P +>To work around this problem Samba compresses the 32 bit range into 31 +bits by appropriate bit shifting. This seems to work but is not +ideal. In a future version a separate SMB lockd may be added to cope +with the problem.</P +><P +>It also doesn't help that many unix lockd daemons are very buggy and +crash at the slightest provocation. They normally go mostly unused in +a unix environment because few unix programs use byte range +locking. The stress of huge numbers of lock requests from dos/windows +clients can kill the daemon on some systems.</P +><P +>The second major problem is the "opportunistic locking" requested by +some clients. If a client requests opportunistic locking then it is +asking the server to notify it if anyone else tries to do something on +the same file, at which time the client will say if it is willing to +give up its lock. Unix has no simple way of implementing +opportunistic locking, and currently Samba has no support for it.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN570">Deny Modes</H2 +><P +>When a SMB client opens a file it asks for a particular "deny mode" to +be placed on the file. These modes (DENY_NONE, DENY_READ, DENY_WRITE, +DENY_ALL, DENY_FCB and DENY_DOS) specify what actions should be +allowed by anyone else who tries to use the file at the same time. If +DENY_READ is placed on the file, for example, then any attempt to open +the file for reading should fail.</P +><P +>Unix has no equivalent notion. To implement this Samba uses either lock +files based on the files inode and placed in a separate lock +directory or a shared memory implementation. The lock file method +is clumsy and consumes processing and file resources, +the shared memory implementation is vastly prefered and is turned on +by default for those systems that support it.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN574">Trapdoor UIDs</H2 +><P +>A SMB session can run with several uids on the one socket. This +happens when a user connects to two shares with different +usernames. To cope with this the unix server needs to switch uids +within the one process. On some unixes (such as SCO) this is not +possible. This means that on those unixes the client is restricted to +a single uid.</P +><P +>Note that you can also get the "trapdoor uid" message for other +reasons. Please see the FAQ for details.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN578">Port numbers</H2 +><P +>There is a convention that clients on sockets use high "unprivilaged" +port numbers (>1000) and connect to servers on low "privilaged" port +numbers. This is enforced in Unix as non-root users can't open a +socket for listening on port numbers less than 1000.</P +><P +>Most PC based SMB clients (such as WfWg and WinNT) don't follow this +convention completely. The main culprit is the netbios nameserving on +udp port 137. Name query requests come from a source port of 137. This +is a problem when you combine it with the common firewalling technique +of not allowing incoming packets on low port numbers. This means that +these clients can't query a netbios nameserver on the other side of a +low port based firewall.</P +><P +>The problem is more severe with netbios node status queries. I've +found that WfWg, Win95 and WinNT3.5 all respond to netbios node status +queries on port 137 no matter what the source port was in the +request. This works between machines that are both using port 137, but +it means it's not possible for a unix user to do a node status request +to any of these OSes unless they are running as root. The answer comes +back, but it goes to port 137 which the unix user can't listen +on. Interestingly WinNT3.1 got this right - it sends node status +responses back to the source port in the request.</P +></DIV +><DIV +CLASS="SECT1" +><HR><H2 +CLASS="SECT1" +><A +NAME="AEN583">Protocol Complexity</H2 +><P +>There are many "protocol levels" in the SMB protocol. It seems that +each time new functionality was added to a Microsoft operating system, +they added the equivalent functions in a new protocol level of the SMB +protocol to "externalise" the new capabilities.</P +><P +>This means the protocol is very "rich", offering many ways of doing +each file operation. This means SMB servers need to be complex and +large. It also means it is very difficult to make them bug free. It is +not just Samba that suffers from this problem, other servers such as +WinNT don't support every variation of every call and it has almost +certainly been a headache for MS developers to support the myriad of +SMB calls that are available.</P +><P +>There are about 65 "top level" operations in the SMB protocol (things +like SMBread and SMBwrite). Some of these include hundreds of +sub-functions (SMBtrans has at least 120 sub-functions, like +DosPrintQAdd and NetSessionEnum). All of them take several options +that can change the way they work. Many take dozens of possible +"information levels" that change the structures that need to be +returned. Samba supports all but 2 of the "top level" functions. It +supports only 8 (so far) of the SMBtrans sub-functions. Even NT +doesn't support them all.</P +><P +>Samba currently supports up to the "NT LM 0.12" protocol, which is the +one preferred by Win95 and WinNT3.5. Luckily this protocol level has a +"capabilities" field which specifies which super-duper new-fangled +options the server suports. This helps to make the implementation of +this protocol level much easier.</P +><P +>There is also a problem with the SMB specications. SMB is a X/Open +spec, but the X/Open book is far from ideal, and fails to cover many +important issues, leaving much to the imagination. Microsoft recently +renamed the SMB protocol CIFS (Common Internet File System) and have +published new specifications. These are far superior to the old +X/Open documents but there are still undocumented calls and features. +This specification is actively being worked on by a CIFS developers +mailing list hosted by Microsft.</P +></DIV +></DIV +><DIV +CLASS="CHAPTER" +><HR><H1 +><A +NAME="TRACING">Tracing samba system calls</H1 +><P +>This file describes how to do a system call trace on Samba to work out +what its doing wrong. This is not for the faint of heart, but if you +are reading this then you are probably desperate.</P +><P +>Actually its not as bad as the the above makes it sound, just don't +expect the output to be very pretty :-)</P +><P +>Ok, down to business. One of the big advantages of unix systems is +that they nearly all come with a system trace utility that allows you +to monitor all system calls that a program is making. This is +extremely using for debugging and also helps when trying to work out +why something is slower than you expect. You can use system tracing +without any special compilation options. </P +><P +>The system trace utility is called different things on different +systems. On Linux systems its called strace. Under SunOS 4 its called +trace. Under SVR4 style systems (including solaris) its called +truss. Under many BSD systems its called ktrace. </P +><P +>The first thing you should do is read the man page for your native +system call tracer. In the discussion below I'll assume its called +strace as strace is the only portable system tracer (its available for +free for many unix types) and its also got some of the nicest +features.</P +><P +>Next, try using strace on some simple commands. For example, <B +CLASS="COMMAND" +>strace +ls</B +> or <B +CLASS="COMMAND" +>strace echo hello</B +>.</P +><P +> +You'll notice that it produces a LOT of output. It is showing you the +arguments to every system call that the program makes and the +result. Very little happens in a program without a system call so you +get lots of output. You'll also find that it produces a lot of +"preamble" stuff showing the loading of shared libraries etc. Ignore +this (unless its going wrong!)</P +><P +>For example, the only line that really matters in the <B +CLASS="COMMAND" +>strace echo +hello</B +> output is:</P +><P +><TABLE +BORDER="0" +BGCOLOR="#E0E0E0" +WIDTH="100%" +><TR +><TD +><PRE +CLASS="PROGRAMLISTING" +>write(1, "hello\n", 6) = 6</PRE +></TD +></TR +></TABLE +></P +><P +>all the rest is just setting up to run the program.</P +><P +>Ok, now you're familiar with strace. To use it on Samba you need to +strace the running smbd daemon. The way I tend ot use it is to first +login from my Windows PC to the Samba server, then use smbstatus to +find which process ID that client is attached to, then as root I do +<B +CLASS="COMMAND" +>strace -p PID</B +> to attach to that process. I normally redirect the +stderr output from this command to a file for later perusal. For +example, if I'm using a csh style shell:</P +><P +><B +CLASS="COMMAND" +>strace -f -p 3872 >& strace.out</B +></P +><P +>or with a sh style shell:</P +><P +><B +CLASS="COMMAND" +>strace -f -p 3872 > strace.out 2>&1</B +></P +><P +>Note the "-f" option. This is only available on some systems, and +allows you to trace not just the current process, but any children it +forks. This is great for finding printing problems caused by the +"print command" being wrong.</P +><P +>Once you are attached you then can do whatever it is on the client +that is causing problems and you will capture all the system calls +that smbd makes. </P +><P +>So how do you interpret the results? Generally I search through the +output for strings that I know will appear when the problem +happens. For example, if I am having touble with permissions on a file +I would search for that files name in the strace output and look at +the surrounding lines. Another trick is to match up file descriptor +numbers and "follow" what happens to an open file until it is closed.</P +><P +>Beyond this you will have to use your initiative.
