I believe that Julian was the first corporately employed person, who had at least part of his paid job as working on the 386BSD/FreeBSD code.

Some of the people who later split off NetBSD and released the NetBSD 0.8 release had reverse engineered the patchkit format, and built tools to do the same thing. Not understanding the fact that the patchkit was in fact a simple, single user revision control system that I had hacked together, they released patches of their own, starting at #1000. This resulted in problems with serialization, and, I believe, was one of the main factors in their going off on their own. Progress was made on the 386BSD 0.5 release under the auspices of the patchkit maintainers, who had their position of control because I did not distribute the patchkit patch making shell scripts very widely, in order to ensure serialization, so that the patches, when applied, would work, have proper dependency tracking, and not result in conflicts. There was an angry posting on Usenet by Lynne Jolitz; in it, she claimed that 1/3 of the patchkit was good, 1/3 was benign (but unnecessary), and 1/3 was crap. Then she would not say which 1/3 was which; this pissed off more people than the original claim that only 1/3 of the code was any good. After much sniping back and forth, Bill Jolitz posted, and revoked his previous permission to use the 386BSD name (a common law trademark belonging to him), and therefore he had effectively scuttled the interim release under the 386BSD name.

FWIW: This is all archived on Minnie, thanks to Warren Toomey. Sure, and I've got archives of it as well. I believe that Julian was the first corporately employed person, who had at least part of his paid job as working on the 386BSD/FreeBSD code. Yes, and the original SCSI system was Julian's, which was later replaced by CAM. Bill Jolitz approved a 0.5 interim release of 386BSD And then Lynn revoked this, and posted a public message to the world stating what obnoxious fiends we were. As the person who spoke with both Bill and Lynn getting their approval (Jordan did as well), I'm *very* familiar with the process. Some of the people who later split off NetBSD and released the NetBSD 0.8 release had reverse engineered the patchkit format, and built tools to do the same thing. Actually, no. It was the person who was going to take it from me (I could name him, but it wouldn't do much good). The new maintainer didn't do anything or respond to email for over 3 months, so Jordan took it over from where I left off. NetBSD was Chris Demetriou's child after he got fed up with Bill's promises never coming true. I was the third committer on what would later become the NetBSD development box, but I still naively assumed that Bill's promises would eventually come to fruition. NetBSD happened when Lynn's famous email was sent out claiming we were all evil incarnate, and that no-one understood them anymore. Soon afterward NetBSD 0.8 was released, but Adam Glass (the owner of the second account on the NetBSD development box) was a big 68K fan, so his influence (as well as Chris's) made NetBSD into a cross-platform OS. Progress was made on the 386BSD 0.5 release under the auspices of the patchkit maintainers, who had their position of control because I did not distribute the patchkit patch making shell scripts very widely, in order to ensure serialization, so that the patches, when applied, would work, have proper dependency tracking, and not result in conflicts. Actually, all of the patchkit maintainers (myself, Jordan, and Rod) had access to your shell software. However, it turned out that avoiding conflicts was hard, because serialization often required patches upon patches upon patches upon patches, and at some point, the creation/maintenance of the patchkit was greater than building a new release. (Plus the fact that you couldn't install the patches w/out a running system, and the running system couldn't be installed on certain hardware w/out patches, causing a catch-22). There was an angry posting on Usenet by Lynne Jolitz; in it, she claimed that 1/3 of the patchkit was good, 1/3 was benign (but unnecessary), and 1/3 was crap.

Topic: rmuser contains a race condition exposing /etc/master.passwd Category: core Module: rmuser Announced: 2001-09-04 Credits: [EMAIL PROTECTED] Affects:FreeBSD 4.2-RELEASE, 4.3-RELEASE FreeBSD 4.3-STABLE prior to the correction date. Corrected: 2001-07-28 12:10:15 UTC (4.3-STABLE) 2001-09-04 07:46:57 UTC (RELENG_4_3) FreeBSD only: Yes I. Background rmuser is a perl script used to completely remove users from a system. II. Problem Description When removing a user from the system with the rmuser utility, the /etc/master.passwd file and it's corresponding database /etc/spwd.db must be updated. The rmuser script was incorrectly doing this by creating a new master.passwd file with an unsafe umask and then using chmod to set its permissions to 0600. Between the time that the file was created and the time that its permissions were changed the file is world-readable. This is only a minor security vulnerability since the rmuser command is only used infrequently on most systems, and the attack is highly timing-dependent. All versions of FreeBSD prior to the correction date including FreeBSD 4.3 contain this problem. The base system that will ship with FreeBSD 4.4 does not contain this problem since it was corrected prior to the release. III. Impact For a brief amount of time while running rmuser, a world-readable copy of /etc/master.passwd is available. A local attacker who reads this file can extract password hashes from the copy of /etc/master.passwd. This information could be used by attackers to escalate their privileges, possibly yielding root privileges on the local system, by mounting an offline dictionary attack in order to guess the plaintext passwords of the accounts on the local system. IV. Workaround Use the pw(8) utility to remove users instead of rmuser. - pw userdel username will only remove the user from /etc/passwd, /etc/master.passwd and /etc/group - pw -r userdel username will also remove the user's home dirrectory V. Solution 1) Upgrade your vulnerable system to 4.3-STABLE or the RELENG_4_3 security branch, dated after the respective correction dates. 2) To patch your present system: download the relevant patch from the below location, and execute the following commands as root: # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-01:59/rmuser.patch # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/patches/SA-01:59/rmuser.patch.asc Verify the detached PGP signature using your PGP utility. This patch has been verified to apply to FreeBSD 4.2-RELEASE and 4.3-RELEASE. It may or may not apply to older, unsupported releases of FreeBSD. # cd /usr/src/usr.sbin/adduser # patch -p /path/to/patch # make depend make all install 3) FreeBSD 4.3-RELEASE systems: An experimental upgrade package is available for users who wish to provide testing and feedback on the binary upgrade process. This package may be installed on FreeBSD 4.3-RELEASE systems only, and is intended for use on systems for which source patching is not practical or convenient. If you use the upgrade package, feedback (positive or negative) to [EMAIL PROTECTED] is requested so we can improve the process for future advisories. During the installation procedure, backup copies are made of the files which are replaced by the package. These backup copies will be reinstalled if the package is removed, reverting the system to a pre-patched state. # fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/packages/SA-01:59/security-patch-rmus er-01.59.tgz # fetch

It is also available on CDROM from Austin | Code Works ([EMAIL PROTECTED]) [Note -- this is unpatched 0.1 -- you should | get the patchkit in /unofficial on agate, and also the FAQ]. I was involved with the entire affair, and Warren's archive doesn't include much of what later became 'core' email.

I hope someone, somewhere has saved it for posterity... Also, it doesn't include the phone conversations with Bill and Lynn, which (obviously) aren't in the public domain. Nor mine. Actually, in California, Utah, and Montanna, and now many more states, so long as one party to the conversation is the one doing the recording, you don't even have to have the periodic beep to indicate a recording... even back then. But I never even considered recording my calls, and I rather doubt that anyone else had the foresight to do it, either. It's annoying in retrospect, because I had the equipment for doing passive monitoring without violating the phone company rules on connecting equipment to their wires. 20/20 hindsight... 8-(. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Re: Should URL's be pervasive.
Kevin Way [EMAIL PROTECTED] types: You can even do this in userland with an nfs server API if you want it to be portable. Novel idea. I'll file it into the maybe pile. Old idea. I first saw an ftp version of this in '91 or '92. Last time I went looking for source code, I couldn't find it, so I have no idea who to credit. I don't know of any application that handles local files that responds to any open error by prompting for a password. If open can now return an HTTP 401 error, every application is going to need to be able to deal with that in some sane way. Either that, or users are going to have to know the proper syntax for usernames and passwords in every URL scheme they deal with - and start putting passwords on command lines, and other things that give security officers nightmares. I would imagine that an http filesystem layer would return EACCES for a 401, as that would probably cause any program to return a sane error to the user. Hopefuly, an http file system will have options to let you specify a username and password, so you can mount password-protected volumes that way. Or possibly a place to specify an authentication realm file, giving username/password pairs for the various different realms that might be in the mounted tree. Yes, unfortunately all ideas are just a Simple Matter of Programming... One miscommunication I should apologize for, I'm not suggesting the URLification of FreeBSD. I'm suggesting that it would be a Good Thing if files available via any common networked file transfer protocol were able to be accessed via standard system calls. I can't argue that having that capability on a workstation would be nice. I don't think it's something I'd make a lot of use of, and I'm not really interested in adding it. Anyway, in conclusion it would seem to me that we agree, but there was a misunderstanding because I did a poor job of clipping relevant text to show what it was I was agreeing with. I think it's more a case of topic drift. This thread started with the observation that URLs were ubiquitous, and asked whether or not they should be pervasive as well. Your - and presumably Mike's - proposed solution doesn't deal with that at all. In summary, each command needs to decide - possibly on a case-by-case basis whether or not the string it's got is a URL or a file name. It needs to decide how the operation it's been asked to be performed can be performed on the object that URL represents, and if so how it should be mapped. If it's a URL, the application may well have to deal with events that don't happen with local files. I really don't want all that in every command. I want it in a filesystem layer, where appropriate, as described above. I agree about that. On the other hand, there are commands that take arguments with information that can be put into a url. Because URLs are ubiquitous, it would be nice if those commands would extrat that information for you. I.e. - ncftp grew the ability to deal with FTP urls. fetch carries that even further. I can see wanting a mail composition program that would recognize a mailto URL on the argument line, and pull out the address and subject for you. One of the suggestions that fell out of this was that there be a shell command for doing these kinds of things. While I like that idea, I think the shell command should be a wrapper around some library calls, so that this kind of thing can easily be added to commands where appropriate. Especially since we already have half the functionality - if in a crippled form - in libfetch. This is something I'm willing to work on, and have even started on. I submitted PR 30318, which adds the missing half the functionality to libfetch - but doesn't do any healing of the first half - and a small program that tries to act like the url command described earlier on the thread. I apologize for the miscommunication. I don't think one is necessary, or if one is, I need to apologize as well for missing the change in direction. mike -- Mike Meyer [EMAIL PROTECTED] http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.

Re: SLOW ftp transfers one way
you should check the settings of your switch ports and look into the output of 'ifconfig -a'. try nailing the switch to 100baseTX.full duplex and set up the network card with 'ifconfig fxp0 media 100baseTX mediaopt full-duplex' this solves carrier transition problems with stupid switch hardware which cause throughtput degradation. in the environments i administer, nway autonegotiation is always turned off, both sides are set to 100base/fdup. /k Hans Christensen([EMAIL PROTECTED])@2001.08.30 20:43:38 +: I have recently redefined a problem which has been plaguing me for close to a year now. I have several FBSD boxes at a site fed by a Sprint T1 (Site A). Each of these boxes is capable of ftp'ing to each other on the same subnet at speeds approaching the limits of the disk subsystem. In short, transfers on the LAN between FBSD boxen appear to be fine. In addition, I have enlisted the help of the folks at sprint to ftp in and out of these boxes with speeds approaching the limits of the T1 line - no problem there. It should be noted that the sprint guys have done their transfers from within sprint's network and are therefore NOT crossing their own network access points. Here is where it gets weird. If I ftp into one of my boxes at Site A across the WAN (in this case from a colocation facility) and put a large file onto my server in Site A, I get speeds of about 10KB/s. This may fluctuate from 4KB/s to 16KB/s, but it far below what one would normally see across a T1 line. Interestingly enough, sending ftp traffic out of Site A seems to move five to ten time faster - not perfect, but workable. Below are example of the same file transferred first out of Site A to the colocation facility, and then the same file just transferred, back into Site A. You will note the difference in speeds... This colocation facility is NOT on the same network as sprint and therefore DOES have to cross one of Sprint's network access points. Furthermore, to rule out the possibility that the colo facility is to blame, I ftp'ed from a linux box on yet another ISP's network. This linux box had the same type of performance problems. Slow puts to Site A and reasonable gets from Site A. I have seen this before as well, between boxes at the colocation facility and again across different class c subnets. Sprint claims that the problem lies with the MTU settings of the boxes at the linux side and the colo side. This smells wrong to me, but I confess that I don't really know that it is wrong. I have looked in the FBSD bug reports for any indication of a similar problem and do not see any so far, but I have seen several questions on the mailing list archives. Most of these are dismissed as improper configuration of ethernet cards. I have tried these suggestions but found no relief. I ftp close to a GB of info every night into Site A and I need it to go faster than it has been going, but I'm stumped. Anybody got any clues for the clueless?

usr.sbin/ac change - request for comments
The code of usr.sbin/ac/ includes support for handling :0.0 as
console logins, when CONSOLE_TTY is defined during compilation.
Looking at the code, and revisions from 1.2 and up, this doesn't seem
to be used. Is there any reason why this should not be removed from
the sources. It's not used anyway :/
I'm talking about pieces of code like the following:
#ifdef CONSOLE_TTY
static char *Console = CONSOLE_TTY;
#endif
or parts like the even more exotic:
while ((c = getopt(argc, argv, Dc:dpt:w:)) != -1) {
switch (c) {
...
case 'c':
#ifdef CONSOLE_TTY
Console = optarg;
#else
usage();/* XXX */
#endif
break;
The code is cluttered all over with #ifdef'ed pieces of code that are
not used. Is it really necessary that we keep these parts?

kernel ddb help

Now I have only one machine and the system panic: db trace bqrelse(cxxx, cxxx, cxxx, c, cxxx) at bqrelse+0x25 is there a way to use these addresses to figure out which line or lines of source are suspect to cause the panic?

Re: kernel ddb help
you can gdb -k mykernel /dev/mem and do list bqrelse+0x25 (I think) alternatively, in ddb you can do: x/iii bqrelse and work out what is wrong by reading the machine instructions WHen I have one machine I usually debug by running the new kernel within a VMWARE virtual machine. Using the nmdm driver you can run gdb in the main machine to debug it, all within one machine.

For instance, a company might have a product that's based on RELENG_4, but with some local mods. So FreeBSD-4.x is in effect that company's vendor. I can see how that would work for RELENG_4, but for the HEAD, many of the files on the HEAD in /usr/src/contrib are on vendor branches, which means it would be a *nightmare* to get that right (IMO). It would still work just the same. You're just checking out -current and importing it onto your own vendor branch. You don't know or care about FreeBSD's vendor branch. Of course (and this is one of the big complications), CVSup would have to map the version numbers somehow. Another big complication would be that at some point in the future a user would want to switch from being based on RELENG_4 to being based on RELENG_5. I have a feeling that could get tricky for CVSup to deal with. Although, it may not be as useful to developers, who often have to track development in multiple branches (for MFC's).

Probably switching to FreeBSD and the kqueue interface would better match your problem. Let's do some setup, and then guess at what you wanted to do, and give you several approaches to our satisfying our guesses... Short answer: You can't. The suspended state is an attribute of the thread that is controlled by the threads scheduler, and is not directly controllable by you. A thread is guaranteed to be suspended only when it is waiting on a mutex, condition variable, or blocking call (such as I/O). I suggest you rethink your design. If the intent is to get an immediate context switch back to yourself, you will need to create a mutex that can not be acquired by the newly created thread, and attempt to acquire it as the first thing you do. You can then immediately release it so as not to block other threads trying the same dirty trick. Note that there is not an explicit yield, so you will have to do something like this to get a yield equivalent. Alternately, if the intent is to create threads so that they will be around when you need them, you would be better off delaying their creation until you need them. The expensive part of threads creation is _supposed_ to be the allocation of the stack; so if you keep a pool of preallocated stacks lying around for your use, you will get only a small startup latency. If the intent is to have a pool of idle threads, ready to go when you get request traffic, and get around the latency, well, you'd do a lot better in the latency department if you went to a finite state automaton, instead of messing with threads. But if you insist, the best you are going to be able to get is use of a mutex, since a condition variable will result in a thundering herd problem. You will still have to eat the latency for the mutex trigger to the thread you give the work to, however (this is how I designed the work-to-do dispatcher in the Pathworks for VMS (NetWare) product for DEC and Novell). If the intent is a horse race, where you create a bunch of threads, and then open the starting gate and have them all start going ``at once'', then you want a condition variable. I intentionally quoted ``at once'', since the concurrency will not be real without multiple CPUs and cooperation from the OS, it will be virtual -- just as if you were running multiple processes, instead of trying to use threads. This is an artifact of the scheduler, and varies from implementation to implementation. Note: I don't know what level of standards compliance the HP-UX 11 version of pthreads has achieved; some of the things described above are probably not going to be easy to achieve in downrev versions of the library. Last time I looked, the HP-UX version of pthreads was a Draft-4 version, not a Draft-10 or standard version, so you may be in more trouble than you originally thought; specifically, you will have a problem with creating a preinitialized mutex in a Draft-4 version of pthreads, so you will have to create the mutex (if you use one) first. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

It worked, but I got a cramp: the local copy was so expensive compared to an integrated approach, that it was not worth maintaining.

The new option (PCI_ALLOW_UNSUPPORTED_IO_RANGE) allows me to boot my old HP Omnibook 4150 while docked. Since I've seen a couple other people need this fix, I figure it would be more useful if they just had to add a line to their kernel config instead of editing the source files.

post 2.95.3 patches to test
Hi all, This patch has the official GCC 2.95 fixes for sjlj exceptions. As you may know, the ones we have in our tree are the sjlj changes that were in 2.95.3.test3, but removed for 2.95.3.test4. I would like to apply this patch to -current and then -stable afterwards. I have one good report, from a very good FreeBSD GCC tester. But before I commit it, I would not mind hearing any one else's experiences with it. Replying to the list so all can see is preferred. -- -- David ([EMAIL PROTECTED]) Index: ChangeLog === RCS file: /home/ncvs/src/contrib/gcc.295/ChangeLog,v retrieving revision 1.1.1.12 diff -u -r1.1.1.12 ChangeLog --- ChangeLog 2001/03/19 19:46:16 1.1.1.12 +++ ChangeLog 2001/08/30 21:05:19 @@ -1,3 +1,160 @@ +2001-08-29 David O'Brien [EMAIL PROTECTED] + + * config/alpha/crtbegin.asm: The normal calling convention for alpha is + to re-initialize gp using 'ldgp gp,0(ra)' after a jsr instruction. + +2001-06-19 Bernd Schmidt [EMAIL PROTECTED] + + * regmove.c (optimize_reg_copy_3): Do nothing if previous insn + carries a REG_EQUIV note.

Re[2]: auto relaying for subdomains -- why?
poige I noticed that some mailers (sendmail, postfix) in case they allow
poige relayingforsomedomain.zonealsoallowrelayingfor
poige subdomain-of.somedomain.zone.
poige I can accept this as reasonable behavior but would like to know how to
poige deny it! :) Also I wish to know what was the actual idea behind this?
From /usr/share/sendmail/cf/README:
+--+
| FEATURES |
+--+
Available features are:
relay_hosts_only
By default, names that are listed as RELAY in the access
db and class {R} are domain names, not host names.
For example, if you specify ``foo.com'', then mail to or
from foo.com, abc.foo.com, or a.very.deep.domain.foo.com
will all be accepted for relaying. This feature changes
the behaviour to lookup individual host names only.
Yes, I saw this info here:
http://www.sendmail.org/m4/features.html#relay_mail_frombut most
valuable part of my question was about the purpose or the idea behind
this, cause it's not too clear to me why allowing relaying for domain
FOO.BAR should allow relaying for SUB.FOO.BAR? I mentioned RFCs
because I had a hope to find out the answer from it but still haven't
yet...

Sendmail does _not_ do this by default; you have to specifically allow it by adding entries to your M4 file from which you build your sendmail.cf. If I had to guess, I'd guess that you enabled the domain via a sendmail.cw file, Ieh :) But what is wrong with that? it just says to sendmail that he is the end point for mail destined to @foo.bar. Now it's named /etc/mail/local-host-names rather than a virtusertable, or by setting yourself up as a promiscuous relay. no... no for these gueses :) -- Terry -- Igormailto:[EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

But that time I wasn't sure whether it is a SENDMAIL's feature (local configuration as you said after) or it's required/described in RFC. This was the start :) Now it's all clear :) and I understand that it was just a way SENDMAIL's is configured.

I'm not quite sure should I start new thread or can remain within it with another question which is: What MTA software supports highly configurable relaying... One of the needed features is a support for using alternative mail routers (relays) in case when this MTA can't send a message by itself because of networks problem. For example situation could be: MTA is on a network A which is temporarily cut off from it's uplink so it can't transfer mail by itself, but it has a connection (permanent or dial-up) to another mailer. Are there such MTAs which can be said if you can't send it by yourself (would be cool if additional parameters were some_time_period and failure_reason) then use that MTA (ip-addr) or that (another-ip)?.

Re: SO_REUSEPORT on unicast UDP sockets
Mike Silbersack wrote: Similarly, there are a number of bugs in the TCP sockets as well; specifically, there's a problem with all sockets being treated as being in the same collision domain, when doing automatic port assignment. This limits you to 65535 oubound TCP connections, even though you have multiple IP aliases on an interface (theoretically, you should get 64k connections per IP address, if you bind _not_ to IN_ADDR_ANY, but instead use a specific port, but the hash is broken). I like this problem's evil sibling: client side TIME_WAITs. If you build them up, you just sit there unable to allocate outgoing ports until they time out. If you fix or workaround the source IP address problem, and patch/tune the kernel for enough outbound sockets, you can go to 250,000 outbound connections very easily. I used a couple of 1GB memory systems in this configuration to get my 1M (actually, closer to 2M) inbound server connections... obviously, a server doesn't have the port limitation, when it comes to accepting connections. The client TIME_WAIT problem is more an issue for port reuse; for a 2MSL timer in the standard 60 second range, this will basically limit you to 65535/60, or ~1000 outbound connections a second per IP address, as a sustained rate, with a total outstanding count of 65535 * IP_address_count. Unless you set SO_REUSEPORT/SO_REUSEADDR. So for the client side, you are pretty much limited by the bug (or your fix), and whatever you set the 2MSL timer down to, as a sustained rate top end. For most real world uses, apart from test equipment, which will usually just use raw sockets directly, and fake the AYN/ACK for the SYN, and then accept the ACK without an RST, you never really get up into this number of client connections on a single box. Maybe net or openbsd handle these situations better, I'll have to check later. I doubt it. Until I did testing on 4.3, no one had really run over 32,766 open sockets in a production server, since at that point, the ucred reference count overflowed, which would result in some strange and very hard to identify crashes, when closing those connections. Alfred fixed this in -current, but it wasn't done consciously to address a known problem, it was done just in case (Alfred finds problems like that, and fixes them without necessarily being aware of it... 8-)). It hadn't been MFC'ed back to 4.3 until I identified an actual problem, and the root cause. NetBSD and OpenBSD have some hacks on the server side of the scaling problem (e.g. they have each implemented a SYN cache, which is OK as far as it goes, but is really inferior to the SYN cache and rate halving algorithm code (also against FreeBSD) out of the Pittsburgh Supercomputing Center. I've done a preliminary port of the PSC code to 4.x, actually, though I would need to strip out a number of local changes. One interesting thing about the SYN cache code is that it could use the tcptmpl allocation until it saw the ACK (or even the first data, as was suggested by some of the researchers at that startup in India, a while back, though that's very aggressive). Mostly, you aren't going to see the hashing on both source and detination IP's and ports -- what you'd see in an L2/L3 switch, if you were building one -- which would let you reuse the local pair, so long as it was associated with a different remote pair. That's probably the real long term fix, if there is one. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message
