Besides your hack doesn't find my ZIP drive, and makes it fail miserably. In that case, I'll fix it to do a strstr or something like that. What's your ZIP drive say? If its just that you are unsatisfied with only max 32K transfers, thats another matter, and stuff for later changes. No, it does not work at all with that maximum set. I'm using the disk to hold an FFS filesystem, and mounting it, BTW. See, in the old driver, it limited the transfer, but it ALSO queued the rest of the transfer. AFD doesn't, and I can tell this because I get random parts of kernel memory interspersed with my files (that's the corruption), so I know all of the buffer is not being filled. You need to queue the rest of the transfer too. -S?ren To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-current in the body of the message Brian Feldman_ __ ___ ___ ___ ___ gr...@unixhelp.org_ __ ___ | _ ) __| \ FreeBSD: The Power to Serve! _ __ | _ \ _ \ |) | http://www.freebsd.org _ |___)___/___/ To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-current in the body of the message

It means that nobody is probably willing to go bring up a MAME environment just to test this. You need to isolate it to a more minimal test case if you want people to jump on what could be a local problem (some serial hardware is better behaved than others) or a misbehaving X server (which is masking interrupts for too long; see mailing list archives on this topic). The more complex your reproduction case, in other words, the less likely it is that anyone will respond to it. Hmm, so now you're the second to cite the possibility of X masking interrupts too long, eh? ;) Actually, I use MAME all the time, and this problem does NOT occur (XF86_SVGA on an S3 ViRGE/DX). Oh, user-ppp too of course. If I could have reproduced this problem, I would have replied. If you can say here's a small stand-alone C program which hogs things to the extent that the serial driver seriously overruns its buffers then it's likely that someone will be at least motivated to compile, run and try it. If it involves running some esoteric application which requires downloading data of questionable legality on top of it, it's far less likely that anyone will even bother to look.

On Fri, 30 Apr 1999, Matthew Dillon wrote: Well, what it comes down to is the number of developers actively developing the codebase. We had some truely unfortunate timing with people leaving and new people coming on, and pieces of the system ( such as NFS ) that simply were left dangling for a long period of time with nobody actively locating or fixing bugs. There have been too many critics and not enough people getting into the guts of the code and fixing things. ( Of course, I'm *very* biased here in my opinion :-) ). What it comes down to is that a whole lot of changes were made between 2.2.x and 3.0 without enough debugging by the authors. This kinda resulted in a partially rotting code base even through the 3.1 release, until a number of us got sick and tired of it and started actively tracking down and fixing the bugs. I expect the 3.2 release to be a really good release. It is true that -current has been, more often then not, more stable then -stable in the last two months. This is because fixes were being made to -current more quickly then they could be backported to -stable. Most of these fixes *have* been backported at this point. There are still a few that have not that are on my hot list ( and still not addressed, even with prodding ). There are also a few bug fixes that simply cannot be backported to stable without some pain ( i.e. require the complete replacement of a number of subsystems ), and pain is not in the cards with the 3.2 release so close. It is hard enough dealing with two branches of the source tree. I will personally take my Super Soaker 5000 to anyone suggesting that we have *three* . Sqirt sqirt sqirt! 5000 is out? YES!!! I am hoping that we will be able to accomplish a major synchronization after the 3.2 release. I personally believe that -current is stable enough that we should do one big-assed commit to sync -stable up to the current -current and then continue as per normal. I only wish EGCS hadn't been incorporated quite yet. At the very least, I want to sync *my* stuff up ( NFS/VM/VFS/BIO/VN/SWAPPER ).

I think /etc/login.conf is properly parsed, because if i assign a user to a class that is not defined in login.conf i get complaints, but other than that i am unable to limit login time... Any hints ? That's also my impression. I glipmsed the whole source tree and I couldn't find any place where the limits are enforced. BTW. what entity should enforce login time limits? Kernel? Some user-space daemon? To report a login.conf success, i've used on a 2.2.8 system the cputime ressource limit. I set it to zero and that worked very well. So may be only some limits are implemented ? If you'd like to see where the ones which are implemented are implemented, look at the process context-switch routines in the kernel. Not having checked, but guessing, I bet login reads login.conf as a db and uses the values to set rlimits, which is where they would be set.

Is not this a natural semantics? Why can a program die because _another_ program ate up all the rest of the memory? [ML] This is a common problem for any OS that implements memory overcommit. This means that it is not possible to detect an out-of-swap condition sinchronously as the swap is reserved only when the pages are dirtied and not when brk is grown. This means that you can set brk a gigabyte higher (given that your user limits allow that), and you will not be using swap as long as you do not write to the pages you allocated to the process. Another strategy is to reserve the swap space as soon as it is allocated by the program. This strategy is much more conservative and inherently safer, but it needs much more space: for instance, if you have a program with WSS of a gigabyte and you want to system( date ), you will need at least 2 gigs of swap because system() does fork() first which means that you get 2 copies of your big program and the system cannot know that in one of the copies an exec() will be shortly forthcoming--thus, it has to reserve the full WSS for the copy because it will potentially write to all pages of its WSS. An interesting idea would be to mark this process as killable if COW causes an out of swap condition. Another interesting application would be a fork() call that checks this condition and fails if there is potential for overcommit. forkifavail() Basically anyone doing a system(date); should be using vfork (yes i can see when vfork is not sufficient) This would sort of be like a soft limit on memory allocation and hint to the kernel of which processes are the ones causeing overcommit. basically at a certain point, sbrk will fail and forked processes would be marked killable... does this make sense? has the idea of processes running with uid 10 or just root being excempt from this frantic kill ? This isn't really a great idea since it would be changing the Unix API.

But, if two users have processes running, just because one user has 50 processes doesn't mean it should get 50x the cpu as one user who has one process running. If a process is in sleep or blocked(select, IO, whatever), it's taken out of consideration for the cpu, and the full cpu is given to those processes that actually have work to do.

The thing with the processes getting killed twice or two different
processes being killed is due to the latency between sending the signal
to kill the process and the process actually going away. In order to be
killed, the process must be woken up and allowed to run.
Then let's make sure the kill waits before it does that.
malloc() still succeeds because it isn't actually touching the new memory,
and so the system doesn't actually reserve the memory as of the time of
the system call. That is done by the user program later on after malloc()
returns. malloc()'s limitations are based on the process resources, not
available memory.
I use the memory as soon as it's malloced. If it reserves a page, then
pagefaults it into existence, the VM system knows that that page is now
allocated. When I malloc the last available page for user use, the VM
system knows that it's the last page. I dirty it, and there are none
free. If I malloc(), I want to know that there is no more memory, not
have my process killed. This is POMA.
Previously, the POLA, a NULL getting returned, WORKED CORRECTLY. It did this
for a long time. My little test program always showed this, and shows
that now something was broken. I'll attach it to the end.
It would not be appropriate to make malloc() fail in this situation
because
this would result in N random programs getting malloc() failures rather
then one or two processes getting killed. Having N random processes get
malloc() failures can lead to serious instability with processes.
Only bad code doesn't check return values of malloc().
What might help in a situation like this would a way to flag certain
processes as being 'very important' ... that should only be killed as
a last resort, even if they have a relatively large RSS.
Yes, I was thinking of something like this for the X server.

Ok. This is something to watch, then. The corruption is worrysome. It
is odd to get this sort of corruption in a client's buffer cache when
all the file I/O is running over NFS. The real question is : where did
the corruption come from? The client's IDE drive or something originally
on the server?
Are there any dos partitions on the server at all? If not, then the
corruption is occuring on the client. But if the make procedure is not
accessing (much of) the client's hard drive, where on the client could
the corruption be coming from?
This has nothing to do with DOS. In case you didn't get my other hint:

You know, I think a much better idea for being in magic(5) would be
a check for lots of NULLs and calling the file NULL data, rather than

It would affect ports too, breaking a lot of things that know about -lcrypt and have never heard of -lmd. The way I see it, you've got several choices.. 1) add -lmd for the cases where things are compiled static and leave the rest 2) compile libcrypt.a differently to libcrypt.so, ie: add in the md*.o and sha*.o static binaries into libcrypt by using SRCS+= sha.c in the !PIC case YES! Make the mdXXX symbols all weak, so libmd can be added manually! 3) help move ld.so to / so we can link everything dynamic.. :-) ld.so, ld-elf.so.1 SHOULD be in /, and fschg. They're definitely up there in importance with the kernel. This would allow something nice: /stand being a storage location for shared libraries. /stand meaning standalone, hinting that only the root partition is necessary to run a shared program if necessary... let's move /usr/lib ELF libraries to /stand and keep all a.out and static libs (other than libgcc, foo) in /usr/lib. On the other hand, maybe that's a little radical!

EGCS breaks what(1)
Okay, let me be a little clearer ;) What(1) on the kernel no longer works
because previously, the
char sccs[] = { '@', '(', '#', ')' };
char version[] = blahhhfoo;
Was contiguous. However, nowadays, nice EGCS pads 4 bytes (WHY?!?!) between
those. So it appears @(#)\0\0\0\0FreeBSD. in the binary. Of course,
strings are null-terminated... :P I don't know why EGCS does this!

Re: UPDATE4: ATA/ATAPI driver new version available.

DMA is ineffective with file-system use. I can read from the raw device rad0 at 4.5MB/s with a 1mb block size, but when I use iozone performance is around 2.5MB/s. Mounting wd shouldn't affect that, should it? I used the same device special files to mount as before, with ATA_STATIC being used, and noticed this.

On the other hand, the linux emulator needs it so there's a counter-argument for making it a proper syscall outright. Leaving the rfork(2) stuff unmolested and at least resembling it's plan9 origins probably has some merit - adding extra arguments would mess that up. I) clone syscall - The linux emulator needs (and has) a clone syscall: int linux_clone(int flags, void *stack) The value of an exit signal is passed in the lower 8 bits of the flags argument, the linux counterparts to the FreeBSD RF* flags are passed in the balance of the flags argument. I haven't seen or heard of a linux app that calls the clone syscall directly. I know of two apps, linuxthreads and the linux version of WINE, that call the linux glibc version of clone (see below), which is a wrapper for the syscall. The only thing that the linux syscall does, that can't be done easily in FreeBSD using rfork and an appropriate wrapper to rfork, is pass in the exit signal. rfork does have a flag to set an exit signal of SIGUSR1, but it does not conveniently take a parameter to set it more flexibly. OTOH, the only FreeBSD app I know of that actually sets an exit signal other that the default SIGCHLD, is the linuxthreads port noted above. I'm not sure there is really a need for a clone syscall at this point, but if you wanted it, you could just copy the linux_clone code in linux_misc.c . You would have to decide if you want the flags parameter to take the linux flags values, or FreeBSD flags (the emulator has to take the linux values, obviously). My vote: don't bother with a syscall until there's a demonstrated need. II) clone in libc - Linux glibc has a clone call wrapper for the clone syscall, defined as: int clone (int (*fn) (void *arg), void *stack, int flags, void *arg) The stack and flags are passed directly to the clone syscall, and the fn(arg) is the user function the cloned process should execute. Its easy enough to implement this in FreeBSD as a wrapper for rfork. If you want to facilitate porting linux code, you would want the flags argument to take linux flags, which would then be translated into their FreeBSD counterparts before rfork is call. This is what the code in the linuxthreads port does, and you are welcome to commit it. The only issue here is whether people need to port linux code that calls clone directly. As noted above, the only code I know of that calls clone directly is WINE and linuxthreads. All the rest of the code uses pthread_create, which only indirectly calls clone. My vote: I haven't seen the need, but if there is one, lets do it. III) libc rfork wrapper --- It probably would be nice to have a libc rfork wrapper that grafts a stack and a user function onto the rfork'd child process. But, it should probably take FreeBSD flags, and there's no reason to call it clone. John Dyson's thr_fork is one such implementation. Luoqi Chen posted another variation to either -hackers or -current maybe 6-9 months ago. Matt Dillon just posted yet another variation. Or, the linuxthreads port has a variation of the clone call that has the same API as the linux clone call, but takes FreeBSD flags (see clone.S). My vote: its worth doing, but not a top priority. The main issue is to decide what interface would be most convenient. Its not a top priority since the code already exists for those (rare) cases where someone really needs it. And, lets not call it clone. Let's call it rfork() with one extra argument instead then :) I don't see why this is a bad thing. Full backward compatibility is maintained, and it would be easy to implement. -- Richard Seaman, Jr. email: d...@tar.com 5182 N.

I think Richard Seaman has it right: the stack needs to be passed.
Why don't we simply implement the linux clone()? It sounds to me that
it would be trivial.
Let's add another parameter to fork1/rfork():
pid_trfork __P((int, ...)); for userland
struct rfork_args { int flags; caddr_t extra; };
and in the kernel would be:
fork1(p1, flags)
register struct proc *p1;
int flags;
caddr_t extra;
{ foo
}
We, of course, have backward binary and code compatibility outside of the
kernel with the ellipses, and inside the kernel we control it anyway so we
can modify whatever needs to be changed.
:the assembly wouldn't be needed. Hmm... actually... if one were to mmap() a
:stack and as soon as the rfork() returned movl newstack,%esp and whatnot,
:wouldn't this be a pretty simple solution?
No, because one of the processes may overrun the stack before the other
one managed to return from rfork(). The child process cannot use the
old stack at all.
Why would a simple movl be using the stack?

CPUT_WT_ALLOC_DISABLE
Does anyone want a CPU_WT_ALLOC_DISABLE and CPU_WT_ALLOC_ENABLE as separate options? I see a couple changes that should be made to the kernel now: CPU: AMD-K6(tm) 3D processor (300.69-MHz 586-class CPU) Origin = AuthenticAMD Id = 0x58c Stepping=12 Features=0x8021bfFPU,VME,DE,PSE,TSC,MSR,MCE,CX8,PGE,MMX There should be another line, formatted the same, that ALWAYS reports CPU_WT_ALLOC info. This will help in debugging problems with certain hardware, because on K6-2's I get unreliability with write allocation on. For instance, I updated my BIOS lately and observed a crash. On boot -v, I noted that the BIOS was kind enough to turn on write allocation, but on a CPU that it doesn't seem to work well on. I propose an option to turn OFF write allocation instead of just one to turn it on. I also propose the change in CPU info printouts to (more correct spacing and extra line): CPU: AMD-K6(tm) 3D processor (300.69-MHz 586-like CPU) Origin = AuthenticAMD Id = 0x58c Stepping = 12 Features = 0x8021bf FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,PGE,MMX Write Allocation: Disabled 15-16M Caching Enable: No The changes would be better spacing, a write allocation line (for whatever CPUs are supported, notably the K5, K6, K6-[23]), and changing class to the more sensible like (i.e. a K6 really is 686-class, but being socket 7 is 586-like).

I kindof tried this by having my driver put itself in both the wd ad majors in the table, but that doesn't work, because the mount stuff gets confused on the root name somehow, and fails to mount root because the names dont match...

the trap in swtch_com() (frame #15) is here:
/* switch address space */- line 622
movl%cr3,%ebx
cmplPCB_CR3(%edx),%ebx- trap
je 4f
I don't think this line is supposed to cause a trap...
When it says switch address space What exactly do you think it's going to
do? What I mean is, I'm pretty certain this is a good trap =)
The real problem did seem to be the NULL p dereference, as it was obvious
that it could happen in the code.

Re: UPDATE3: ATA/ATAPI driver new version available.

It doesn't lock up like before, but on my LS-120 wdc1: unit 0 (atapi): LS-120 COSM 02 UHD Floppy/0271C09T, removable, iordy it seems to have corrupt reads. In addition, much of the time the ATA code now will not boot my system, failing at atapi_transfer: bad command phase. Fixed problems: Hang on probe on fantom devices. The probe now use a timeout to avoid hangs if no interrupt is received. There has also been more general code clenaups, and some reorgs. As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code. But please tell me how it works for you!

callout changes nit
I make a habit of checking out any interesting kernel changes in full, and one
thing I found in the recent diff by Mr. Wollman for kern_timeout.c is:
+void
+callout_init(c)
+ struct callout *c;
+{
+ bzero(c, sizeof c);
}
That doesn't look correct, does it?
