Re: dropcopyright script
Same here. While it's a nice script and all, I personally want the copyright and associated contact information in a clear and easy-to-find place. In other words, if you get Linus to patch the kernel to do this, then I'm just going to try to get him to patch it back.

2.4.2-pre2 -- Hard hang on warm reboot when the yenta driver attempts to detect the cardbus bridges.
Any debugging tips would be greatly appreciated. When I cold boot my machine with a 3c575 and a Belkin BusPort Mobile inserted in the Cardbus slots, I get the following in my kernel log: NET4: Unix domain sockets 1.0/SMP for Linux NET4.0. Yenta IRQ list 0698, PCI irq11 Socket status: 3020 Yenta IRQ list 0698, PCI irq11 Socket status: 3020 But, if I remove and then reinsert the cards, call_usermodehelper and /sbin/hotplug recognizes and configure both cards, including bringing up eth0. I am able to use both cards with no trouble. Now, if I warm boot the machine, the boot process completely locks up after the line: NET4: Unix domain sockets 1.0/SMP for Linux NET4.0. SysRq commands fail to respond. When I cold boot the machine, lspci -vvxxx gives: 00:04.0 CardBus bridge: Texas Instruments PCI1131 (rev 01) Subsystem: Dell Computer Corporation: Unknown device 007e Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- Reset- 16bInt- PostWrite+ 16-bit legacy interface ports at 0001 00: 4c 10 15 ac 07 00 00 02 01 00 07 06 08 a8 82 00 10: 00 00 00 10 00 00 00 a2 00 01 01 b0 00 00 40 10 20: 00 f0 7f 10 00 00 80 10 00 f0 bf 10 00 10 00 00 30: fc 10 00 00 00 14 00 00 fc 14 00 00 ff 01 00 05 40: 28 10 7e 00 01 00 00 00 00 00 00 00 00 00 00 00 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80: 20 30 24 00 00 00 00 00 00 00 00 00 00 00 00 00 90: 00 3a 74 00 00 00 00 00 00 00 00 00 00 00 00 00 a0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 b0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 e0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00:04.1 CardBus bridge: Texas Instruments PCI1131 (rev 01) Subsystem: Dell Computer Corporation: Unknown device 007e Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- Reset- 16bInt- PostWrite+ 16-bit legacy interface ports at 0001 00: 4c 10 15 ac 07 00 00 02 01 00 07 06 08 a8 82 00 10: 00 10 00 10 00 00 00 02 00 05 05 b0 00 00 c0 10 20: 00 f0 ff 10 00 00 00 11 00 f0 3f 11 00 18 00 00 30: fc 18 00 00 00 1c 00 00 fc 1c 00 00 ff 02 00 05 40: 28 10 7e 00 01 00 00 00 00 00 00 00 00 00 00 00 50: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 60: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80: 20 30 24 00 00 00 00 00 00 00 00 00 00 00 00 00 90: 00 3a 74 00 00 00 00 00 00 00 00 00 00 00 00 00 a0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 b0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 e0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01:00.0 USB Controller: OPTi Inc. 82C861 (rev 10) (prog-if 10 [OHCI]) Subsystem: OPTi Inc.: Unknown device c861 Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- # # Automatically generated make config: don't edit # CONFIG_X86=y CONFIG_ISA=y # CONFIG_SBUS is not set CONFIG_UID16=y # # Code maturity level options # CONFIG_EXPERIMENTAL=y # # Processor type and features # # CONFIG_M386 is not set # CONFIG_M486 is not set # CONFIG_M586 is not set # CONFIG_M586TSC is not set # CONFIG_M686 is not set # CONFIG_MK6 is not set CONFIG_MK7=y CONFIG_X86_WP_WORKS_OK=y CONFIG_X86_INVLPG=y CONFIG_X86_CMPXCHG=y CONFIG_X86_BSWAP=y CONFIG_X86_POPAD_OK=y CONFIG_X86_L1_CACHE_BYTES=32 CONFIG_X86_TSC=y CONFIG_X86_GOOD_APIC=y CONFIG_X86_USE_3DNOW=y CONFIG_X86_PGE=y CONFIG_X86_USE_PPRO_CHECKSUM=y # CONFIG_MICROCODE is not set CONFIG_NOHIGHMEM=y # CONFIG_HIGHMEM4G is not set # CONFIG_HIGHMEM64G is not set # CONFIG_MATH_EMULATION is not set CONFIG_MTRR=y # CONFIG_SMP is not set CONFIG_X86_UP_IOAPIC=y CONFIG_X86_IO_APIC=y CONFIG_X86_LOCAL_APIC=y # # Loadable module support # CONFIG_MODULES=y # CONFIG_MODVERSIONS is not set CONFIG_KMOD=y # # General setup # CONFIG_NET=y # CONFIG_VISWS is not set CONFIG_PCI=y # CONFIG_PCI_GOBIOS is not set # CONFIG_PCI_GODIRECT is not set CONFIG_PCI_GOANY=y CONFIG_PCI_BIOS=y CONFIG_PCI_DIRECT=y CONFIG_PCI_NAMES=y # CONFIG_MCA is not set CONFIG_HOTPLUG=y # # PCMCIA/CardBus support # # CONFIG_PCMCIA is not set CONFIG_SYSVIPC=y # CONFIG_BSD_PROCESS_ACCT is not set CONFIG_SYSCTL=y CONFIG_KCORE_ELF=y # CONFIG_KCORE_AOUT is not set CONFIG_

Bad patch. It should be
if (r >= 0) {
registered_parport = 1;
if (r > 0)
count += r;
}
If pci_register_driver returns < 0, the driver is not registered with
the system.

Re: piix.c and tuning question
hmmm this is my chipset:
Which motherboard do you have?
00:00.0 Host bridge: Intel Corporation 430HX - 82439HX TXC [Triton II] (rev 03)
00:07.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II] (rev 01)
00:07.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II]
i've had irq timeouts but they were due to a slow CD-ROM causing the two DMA drives to
timeout (don't
know why).
ive never seen ide_dmaproc though.
This is my following hdparm config
hdparm -d 1 -X34 -u1 -k 1 /dev/hdb
hdparm -d 1 -X34 -u1 -k 1 /dev/hda
for both drives, one of them us a UDMA66 but this Pentium 200Mhz cant do UDMA even ;/
I have a AP53/AX AcerOpen Motherboard.

According to Documentation/Configure.help:
Intel PIIXn chipsets support
CONFIG_BLK_DEV_PIIX
This driver adds PIO mode setting and tuning for all PIIX IDE
controllers by Intel. Since the BIOS can sometimes improperly tune
PIO 0-4 mode settings, this allows dynamic tuning of the chipset
via the standard end-user tool 'hdparm'.
Please read the comments at the top of drivers/ide/piix.c.
If you say Y here, you should also say Y to "PIIXn Tuning support",
below.
If unsure, say N.
PIIXn Tuning support
CONFIG_PIIX_TUNING
This driver extension adds DMA mode setting and tuning for all PIIX
IDE controllers by Intel. Since the BIOS can sometimes improperly
set up the device/adapter combination and speed limits, it has
become a necessity to back/forward speed devices as needed.
Case 430HX/440FX PIIX3 need speed limits to reduce UDMA to DMA mode
2 if the BIOS can not perform this task at initialization.
If unsure, say N.
Obviously, the BIOS is not performing the DMA mode reduction, and must
be done maually. However, that's about all the information I can gather
about this problem. Has anyone looked at the top of piix.c (other than
the IDE maintainer, that is)? It's quite cryptic:

FWIW, people can also download Alan's patches and Linus' pre-patches from my 'gkernel' CVS at sourceforge. Instructions for anoncvs are on the SourceForge home page, near the bottom: http://sourceforge.net/projects/gkernel/ Check out module 'linux_2_2' or 'linux_2_4'. You --MUST-- use a branch tag when checking out. Branch tags are named based on kernel version, ie.: REL_2_4_1_ac11 REL_2_2_19_pre10 REL_2_4_2_pre3 Using CVS allows easy diff'ing of the full kernel > cvs -z9 rdiff -u -r REL_2_4_1_ac10 -r REL_2_4_1_ac11 linux_2_4 or just a part of the tree > cvs -z9 rdiff -u -r REL_2_4_1_ac10 -r REL_2_4_1_ac11 linux_2_4/drivers/net (as a side note, if you s/REL/hack/ in the above tag names, you get my public CVS tree...)

incremental patches for 2.4*-ac* kernels
Hi all, I think that most of us using modems begin to experience a little pain in downloading latest Alan's patches since they're becoming to be really big (and interesting). Since I have an occasionnal access to a system equipped with a good line, I began to make incremental patches for these kernels. These patches are about 60 kb instead of nearly 2 Mb. Those who are interested can download them from this url : http://www-miaif.lip6.fr/willy/pub/linux-patches/ac/ Of course, they are not signed nor official, and people who want to use them for production would better get them from the official sites. At the moment, only ac9-to-ac10 and ac10-to-ac12 are provided. To use them : - extract official linux-2.4.1 - apply one of Alan's patches (acXX) - apply one of these incremental patches (acXX-acYY) -> you'll get a 2.4.1-acYY Hope this will help people to test and report bugs.

This is a fundamental reason for the > BIOS's existence. It's common knowledge that Linux is often better for hardware testing than Microsoft's pitiful ACT software. Intel and other companies have discovered hardware flaws that Linux exposes which all the Windows (and ACT) testing does not. (see early P4's...) Similarly, most BIOS out there work wonderfully with Windows but often have quirks with Linux. An overall policy of BIOS independence minimizes if not eliminates the chances of such quirks affecting Linux users. Getting a vendor to fix a broken BIOS is like trying to get a reluctant cow out of the barn: oftimes is just doesn't happen, especially if it is a Linux-only problem. Toshiba laptops have had broken ACPI tables for ages, but I have yet to see any BIOS updates regardless of the number of reports sent to Toshiba. Now, that said, in x86 land, we actually -do- allow the BIOS to setup the PCI bus for us, and for the most part, we leave that setup completely alone. grep for 'pcibios_assign_all_busses'... and note it is defined to zero for x86, and 1 for alpha. Finally, minimizing BIOS dependencies is also important for applications like linuxbios -- an embedded firmware that initializes the CPU and DRAM, and then passes control to a Linux kernel to do the rest.

I would think if video drivers were part of the > kernel and had a nice API for X or any other windowing system, would not > only improve performance but would allow competing windowing systems > without having to develop drivers for each. Has anyone thought or > rejected this idea. Yes. Problem is, X is a big old wad of code. It wasn't designed to run in a kernel environment. It isn't easy to rewrite, and getting rid of it isn't currently reasonable for normal desktop Linux systems. So then what, split X, with only the hardware access in the kernel? This can actually reduce performance, by a small or great amount depending on how it is done. Stability would improve a bit, assuming the new drivers have Linux quality rather than XFree86 quality. The gain is tiny, while the difficulty is large. At least we'd get a safe and reliable way to print an oops though. Both options could eat some memory. (but NOT anything like the VM size of an X server, much of which is the video memory itself) Putting the whole thing in the kernel does allow for memory pressure hooks though. Both options cause political troubles. Currently the X server is shared with OS/2 and other crummy systems. If the Linux kernel had serious video drivers for PC hardware, then driver support for the other operating systems would mostly go away. Linux would become a better desktop OS, at the expense of various crummy systems. Both options would tend to hurt people who like to leave X running on a low-memory web or NFS server. For a kernel X server, swapping must be done more-or-less explicitly. Both options cause more work for Linus. This totally kills the idea. See his past postings flaming the GGI/KGI developers. If you ever write this, go ahead and throw in the rest. I mean the window manager, xterm, and a GDK system call even. My hardware can spare the memory, but CPU cycles are way too scarce. Clean design can go screw itself when it eats CPU time. Don't worry about being accepted into the main kernel, because that won't happen no matter what you do. Have fun hacking, and whip XFree86's ass. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Destination Loose UDP in 2.4 (net/ipv4/netfilter)
What is the status of "dloose udp" in 2.4.x? From my reading in a few list archives it seems to have been some sort of a hack, yet it is needed for games such as Asheron's Call to be played behind a firewall. In 2.2.18 the code implementing this seems to be in net/ipv4/ip_masq.c and was controlled by a sysctl "ip_masq_udp_dloose". Is there anything in 2.4.x to replace this functionallity? Is there a way to replace it with an iptables rule?

If you disable cramfs, it will likely work. There seems to be a (init order?) problem when cramfs is enabled. For instance, if I enable cramfs here, my minix gzipped initrd can not mount root.. kernel tries to use reiserfs instead for some unknown reason. I disable cramfs and all is well.

Bug in 2.4.x??
Hi
Well, it may not be a bug, but it sure is bugging me - i have been on this
for more than a week. Well, here goes;
Why is it that my DMA performance under the kernel 2.4.x is worse than the
one under 2.2? I have attached the stats below the mail- information and test
results under both kernels.
I use the following option under rc.local to set dma ;
/sbin/hdparm -c1 -d1 -m16 -X66 /dev/hda
I use resierfs, Iam disappointed that 2.4 results are about 1/3rd and need to
know what to do.
I use a i810 mobo and seagate 8.4 gb hdd
I have tried recompiling the kernel - iam informed a broken .config could
have caused this, but no change.
I have tried random settings with hdparm to tune /dev/hda.
Thanks for your time.
Ashwin

Has anyone thought or > rejected this idea. You should drop this subject as it will only result in flame wars. They have in the past and the result is always the same... 1) XFree86 is about the X window system. We don't give a damn about competing window systems. 2) There isn't a single API that can encompass all hardware. 3) Kernel drivers are OS specific things and XFree86 runs on too many platforms so we won't be able to abandon user-space drivers. At least not any time soon. That said, there are fbdev drivers for XFree86 and there are some hardware-specific solutions like NVIDIA's binary drivers. If you want to do something else, that's your perrogative. But don't waste your time trying to get everybody to agree with you. I won't happen. Sorry to be a bit abrupt, but there have been a few other discussions of this nature in the past and it's best that it doesn't go much further. At least not on XFree86 lists.

Video drivers and the kernel
I was wondering why video drivers are not part of the kernel like every other piece of hardware. I would think if video drivers were part of the kernel and had a nice API for X or any other windowing system, would not only improve performance but would allow competing windowing systems without having to develop drivers for each. Has anyone thought or rejected this idea. Anyway, This was running though my head for a long time and just thought I ask.

Driver for Casio Cassiopia Fiva touchscreen, help with conversionto 2.4
Available at http://people.redhat.com/~sopwith/fidmour-linux.c is a driver for the touch screen used on the Cassiopia Fiva MPC-501 pen computer. It is a rather Bad Hack (seeing as it was built rather blindly to mimic the behaviour of the Windows driver, and has IRQ/port hardcoded in), but it works for me with the 2.2.16 kernel. The device outputs 5 byte packets - 1 status byte, 2 bytes each for X & Y coordinates. The devel branch of GTK+ has support for /dev/fidmour in the Linux framebuffer backend (gtk+/gdk/linux-fb/gdkmouse-fb.c), should you wish to see a code sample. I'm wondering if anyone has a resource that would provide information on porting this driver to the 2.4 kernel. I would welcome comments on this driver, or on the MPC-501 and Linux in general. Bonus points to anyone who actually understands why the driver works and how the hardware works. :) Hope this helps, -- Elliot Who me?

I'm not sure, but when I asked about this in January, I suggested having an
IOCTL that get/set blksize_size[MAJOR(dev)][MINOR(dev)], which didn't seem
to work for me.

If this analysis is correct (and I think it is), changing the block size
doesn't actually solve the problem.
I've got no problems requiring any IOCTL (either block-size-changing or just
a read/write last sector) to check that a device isn't in use somehow prior
to making these calls. Changing a disk's partition table while partitions
are actively in use on it isn't generally a good idea. But, fdisk and other
partition table-changing apps don't do this kind of check now IIRC.
Thanks,
Matt

Crash in request_region while handling kernel parameters
Hello kernel-hackers, I found a problem with kernel 2.4, that makes the kernel crash at bootup, for example when using the UMC8672 VLB IDE controller driver. The problem is in kernel/resource.c. In line 229 some memory for handling new io-regions is kmalloc()ed. This crashes the computer before mem_init(), as it seems. But some drivers, for example the above mentioned one in drivers/ide/umc8672.c, do already claim i/o ports in their kernel parameter driven initialization procedures, so they crash the system. The point to discuss is whether one needs to fix the drivers, to not request i/o space while handling kernel parameters or to fix the kernel to allow this behaviour. As I do not read this mailing list, a currently don't have web access ready, I don't know whether this topic has already been discussed. Currently I helped myself by just commenting out the calls for check_region and request_region in the umc8672.c file, but I know it smells. Please send me a cc if you think you have a decision how to fix the crash.

Yes. The addpart utility just uses the block-layer ioctls to dynamically add and/or remove partitions. What this is doing is just adjusting the kernel's idea of what the current partition scheme is. This has _nothing_ to do with actually reading or writing data from the disk. But it changes the idea of odd and even. A partition can start on an odd sector.

[patch] 2.4.2-pre3: parport_pc init_module bug
Linus,
Here's a patch that fixes a bug that can cause PCI driver list
corruption. If parport_pc's init_module fails after it calls
pci_register_driver, cleanup_module isn't called and so it's still
registered when it gets unloaded.

So a solution would be to
rm -f output.o
g++ -o output.o
touch output.o
I do the touch in the first place because a subsequent link job on
another remote node used to fail if I didn't. NFS caching magic I guess...

It runs faster indeed, and it makes the work more fun and makes the
internet go faster ! (uhhh... or maybe the internet speedup is because
of the Intel CPUs - I forgot...)
Usually how a compile goes is:
a make -j10 spawns concurrent compile jobs. Each job consists of
"spawn on remote node" g++ ... -o somefile.o
"on local node" touch somefile.o
After a truckload of .o files have been generated, it will start
up link jobs, on other remote nodes. I haven't tried this without
the touch trick for a long time.
Each g++ job takes from a few seconds to several minutes depending
on the file and optimization options etc. I think I mainly see this
with the fast jobs... Most .o files are ~1-4 MB and I have about 200
of them.
~200 compilers and ~12 linkers take about 4-5 minutes to complete on
the cluster of three dual machines and two-three single cpus. Producing
about 1.5G of object code in total (yes C++ symbols are HUGE).
So, the touch is _immediately_ after a compile completion. But the
.o file has not been in use on any other machine than the one running
the compiler for hours or at least many minutes (a different compile).
I'll try this without the touch trick and see how things fare...

Yes. The addpart utility just uses the block-layer ioctls to dynamically add and/or remove partitions. What this is doing is just adjusting the kernel's idea of what the current partition scheme is. This has _nothing_ to do with actually reading or writing data from the disk. The ia64 gpt partitioning code defines a partition header at the front of the disk and at the end of the disk. I definetly have a need to read and write to these headers. What this proposed patch does has _nothing_ to do with partitioning :-) It is _only_ to read and write the last sector of the disk. It just so happens that the reason that I have to read that last sector is to read a partition header. > > Anyway, an ioctl just to read the last sector is too silly. > An ioctl to change the blocksize is more reasonable. That may be better, I don't know. That's why this is an RFC. Are there any possible races with that method? It seems to me that you might adversely affect io in progress by changing the blocksize. The method demonstrated in this patch shouldn't do that. > And I expect that this fixed blocksize will go soon. That may be, I don't know that much about the block layer.

Stale NFS handles on 2.4.1
Hi !
I'm running a compilation cluster with various machines now
on 2.4.1 all mounting the same home filesystem over NFS from
the central NFS server.
All machines are 2.4.1 using NFSv3, some SMP some UP.
NFS server is a dual running an SMP kernel
The NFS clients are getting
"Stale NFS handle"
messages every once in a while which will make a "touch somefile.o"
fail.
It's quite annoying and I didn't see it on 2.2 even after the NFS
patches were integrated.
What happens is that one machine will finish compiling, and another
machine will immediately thereafter do a "touch some_output.o". This
"touch" sometimes fails with a stale handle message.
Is this a known problem or should I submit more info ? If so,
what info ?
(no nothing is overclocked, yes I'm using RedHat 7 kgcc)

Re: [patch] 2.4.1, 2.4.2-pre3: APIC lockups

I guess you mean the MIS: counter in /proc/interrupts? This is what it says on
my box after running some 33 interrupts (at a rate of app. 900/second)
through the network/usb IRQ:
cat /proc/interrupts
CPU0 CPU1
0: 31693 32749IO-APIC-edge timer
1: 1208 1174IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade

4: 4689 4567IO-APIC-edge serial
14: 4440 4545IO-APIC-edge ide0
15: 1911 2132IO-APIC-edge ide1
16: 85021 84227 IO-APIC-level es1371, mga@PCI:1:0:0
17: 26 26 IO-APIC-level sym53c8xx
18: 0 0 IO-APIC-level btaudio, bttv
19: 165467 166254 IO-APIC-level eth0, eth1, usb-uhci
NMI: 64376 64376
LOC: 64364 64362
ERR: 0
MIS:647
So, that's about 650 misdelivered interrupts for 33 deliveries (the other
interrupts never gave me any trouble, so I guess the misdelivered ones are all
from IRQ 19), or about .2%
When I load the network and stream some audio over it, the sound becomes a bit
choppy. The MIS: counter only increases when the network (read: IRQ1() is
loaded, a single audio stream (app. 220 int/sec) causes no MISses to occur.
In general, I'd say the stability WITH the patch is good, and timeouts are
withing tolerable levels. If I need something better, I'll probably get myself
a better set of network cards...
So, quick conclusion, this seems a reasonable fix...

Multicast on loopback?
In developing multicast applications, I would like to be able to test locally over the loopback interface. This does not work without adding a bogus route statement to get the kernel to hand up the packets from loopback to my waiting application. This route statement is not necessary with other network drivers, so I assume that adding some logic to the loopback driver would fix this problem. Is it possible to get this added? -Erik G.

A number of kernel hackers are very successfully using UML for doing filesystem and mm development and debugging. With some help from the host, it's also possible to do driver development under UML.

There may be no easy, convenient way right now, but (without having checked anything) it seems to me that you can, also today. Look at the addpart utility in the util-linux package. It will allow you to add a partition disjoint from previously existing partitions. And since a partition can start on an odd sector, this should allow you to also read the last sector. Do I overlook something? Anyway, an ioctl just to read the last sector is too silly. An ioctl to change the blocksize is more reasonable. And I expect that this fixed blocksize will go soon.

No, improving printing support is something that the distribution vendors are supposed to provide. I think you're under the assumption that this support were to be placed in the kernel, it would then become ubiquitous. That may be true, but it's irrelevant. Instead, what is needed is a sort of "standard" that indicates what every Linux distribution should have in addition to the kernel.

[Announce] Version 1.9 of x86 performance counters driver
Version 1.9 of my x86 performance-monitoring counters driver is now available at http://www.csd.uu.se/~mikpe/linux/perfctr/. Summary: Version 1.9, 2001-02-13 - Fixed compilation problems for 2.2 and SMP kernels. [Caused by the kernel not passing "-nostdinc" to gcc, and RedHat 7.0 including 2.4.0 kernel headers in /usr/include/.] - Corrected VIA Cyrix III support. The "VIA Cyrix III" product has apparently used two distinct CPUs. Initial CPUs were a Cyrix design (Joshua) while current CPUs apparently are a Centaur design (Samuel). Added support for "Samuel" CPUs. [NOTE: This could use some testing on real HW. Any volunteers?] - Two corrections in the K7 perfctr event list. - Small tweaks to vperfctr interrupt handling. - Added preliminary interrupt-mode support for AMD K7. Future changes on the perfctr-1.x branch will be limited to bug fixes and updated glue patches for new 2.2 kernels. New features and hardware support will be implemented in the perfctr-2.x branch, but it will only support 2.4/2.5 kernels.

Re: Will the IBM OMNI printer driver be making its way into thekernel tree?
Whoops. The reason I asked about inclusion is that printing is one of the areas that Linux seems to struggle in terms of usability and I thought perhaps it would make sense to modular print drivers in the kernel tree. Since the OMNI driver is ghostscript-based, including it in the kernel is obviously a bogus idea. Sorry for missing the obvious. I do wonder if there are no print drivers that would make sense in the kernel tree. After all, we have USB device drivers in the tree, including scanners, which aren't all that different from printers, are they? I apologize in advance if I am just being incredibly stupid about this.

I'm thinking that it could be a great teaching tool to break and examine structures, variables, process states, as well as an aid to people who may not have a grasp of the entire kernel but need to write device drivers. It's easy for someone who's "grown up" with Linux to know it all so thoroughly that such a tool seems fluff. But even the best mechanics on new cars use complex diagnostic tools to do car repair. Sure there may be experts that designed the engine that wouldn't need it, but large numbers of people need to repair cars or modify them for their purposes. Having tools to aid in that isn't so much a crutch as it is a learning tool. It's like being able to look at the characters of the alphabet individually before one learns to comprehend the entirety of the writings of Buddha. Certainly Buddha doesn't need to know how to read to know his own writings -- and certainly, if everyone meditates and 'evolves' to their Buddha nature, they wouldn't need to read the texts or recognize the letters either. But not everyone is at the same place on the mountain (or even the same mountain, for that matter). In wisdom, one would, I posit, understand others are in different places and may find it useful to have tools to learn to read before they comprehend. Just my 2-4 cents on the matter... -- L A Walsh| Trust Technology, Core Linux, SGI [EMAIL PROTECTED] | Voice: (650) 933-5338 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Re: Will the IBM OMNI printer driver be making its way into the kernel tree?
Maybe I'm missing your point, but why would it go into the kernel tree ? This is all stuff that gets done in userland under Linux. The Omni drivers plugin with Ghostscript and generate output appropriate to the printer. There's no kernel relevance here.

strange bug, alloca suspected
Hi,
I found a strange bug with modprobe/glibc
I supposed this is a bad interaction between gcc alloca(), glibc and modprobe.
Modprobe don't use alloca() correctly, then glibc failed. (stack corruption ?)
This need more investigation.
This mail is sent to glibc, gcc and modutils maintainers.

It's Linux, after all, so 2 minutes after creating this email
2.2.19pre11's announcement was here. I just tested it, and it has the
same problem.
from my config:
ISDN subsystem
#
CONFIG_ISDN=m
CONFIG_ISDN_PPP=y
CONFIG_ISDN_PPP_VJ=y
CONFIG_ISDN_DRV_HISAX=m
CONFIG_HISAX_EURO=y
CONFIG_HISAX_W6692=y
Now, it's just one more crash and back to 2.2.19pre9 for me!
Good luck,
Jurriaan

Is this the ultimate stack-smash fix?
Greetings. This is my first post on linux-kernel, I hope this is appropriate. The recent CERT IN-2001-01 's massive repercussions and CA-2001-02's re-releasing old material in an attempt to coerce admins to update their OS, has led me to think about buffer overrun exploits. I have gained a new appreciation after being rooted twice this month. I believe there is a solution that can be implemented in the kernel (Linux and probably most Unix) that can prevent this type of exploit, has no effect on userspace code, and is minimally obtrusive for the kernel. Making a few assumptions here - I'm writing to confirm or deny this idea. Background: The virtual address space of a Linux process starts at a low address (0?) with a block containing -the executable's code & constant data mmaped read-only from the executable. -the executable's static initialized data mmapped copy-on-write from same file. -more of each of the above, but for shared libraries. each continuous address range from the above is described in a kernel vm_area_struct, and is mapped on demand and placed into hardware page-protection perms (rwx) by the CPU's PMMU hardware and the kernel's fault-handler's. Next, there is a variable ammount of un mapped memory, Followed by the Stack. The stack's vm_area grows downward, unlike the others ( brk() call) and begins at the high address at the top of user space, which varies but is 3GB for a 1GB max mem kernel. beyond this there is no vm_area's, and the page tables contain mappings which are marked supervisor-only (is this right?), and definitely don't contain user code. Next, gcc doesn't generate any code which would be placed in the stack, nor does it generate any calls/jumps to the stack area. Next, buffer overruns are the only source of code whch would execute from the stack, and from what I understand, remote (if not all) buffer overruns depend on this to "work". Solution: if the kernel sets up the CPU's memory management unit (PMMU) so that it won't execute code in the stack address space, the exploits are foiled. Problem: on intel, the page tables page permissions are not flexible enough, so when a page is marked (for userspace) read-write permissions, execute permission is implied. But, intel also has segment descriptors held in the GDT/LDTs, which configure a base address and range, and a different one can be selected for each segment register of a process. Under the current Linux the code segment (CS) has a descriptor from the GDT which allows code to be executed read-only from base address 0 with a range of 4G (i.e. the entire linear address space), and the data segment allows read-write but not execute (can't be loaded into CS register). SO, if the CS descriptor were changed by the kernel to track the bottom of the stack (lower in memory), then any attempt to execute code on the stack would segfault (or another signal to help track exploit attempts) It could get the bottom page address from the vm_area_struct for the stack (are there more than one GROWS_DOWN vm areas in a process?) Currently the CS for all linux programs gets it's descriptor from GDT, so it would have to be manually changed at each task-swap, and perhaps there are segment descriptor and other cache flushing issues, (maybe just store CS limit in the per-task data structure, and update GDT then reload CS at each context change) I realize that the GDT/LDT must be accessible, and that they are in kernel space (above 3GB), but I don't think these go through CS register access controls. The DS segment can be left alone. For other arch's, maybe they have separate read/write/execute perms per page, or something similar to segment descriptors. I would appreciate thoughful comments; anybody who knows why it won't work, tell me, I haven't got my hopes up for the Nobel prize yet :) Cheers, Jeremy - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

RFC974 is a clarification of how to interpret Domain Name System contents in a mail context. RFC821 makes a clear statement about Domains in section 3.7: [...] Whenever domain names are used in SMTP only the official names are used, the use of nicknames or aliases is not allowed. [...] and in RFC974 it is stated: [...] In addition to mail information, the servers store certain other types of RR's which mailers may encounter or choose to use. These are: the canonical name (CNAME) RR, which simply states that the domain name queried for is actually an alias for another domain name, which is the proper, or canonical, name; [...] [...] In my understanding (and I assume that you're familiar with both as you've chosen to insult me by suggesting that I've not read this stuff), this means clearly: "YOU MUST NOT USE AN ALIAS WHENEVER DOMAINS ARE USED IN SMTP". (RFC821) and "THIS NAME IS AN ALIAS FOR ANOTHER DOMAIN NAME, WHICH IS THE PROPER, CANONICAL NAME". This boils down for me to "YOU MUST NOT USE A CNAME ANYWHERE IN SMTP". and "ANYWHERE" also states for me "in the 220 greeting". Any further questions? Regards Henning -- Dipl.-Inf. (Univ.) Henning P.

2.2.19pre10 locks up hard on unloading the isdn module 'hisax.o'
SMP machine, 2x P3/700 on an Abit VP6.
Never any trouble with the earlier 2.2.19pre's.
a strace shows the hang to be in the delete_module("hisax") call.
I'm having trouble with the sysrq-key, but I hope this is enough since
there were some changes w.r.t. modules/locking etc. in pre10.
Good luck,

You can see documentation on Ramdisk in Documentation/ramdisk.txt if you have some time ;) Best Regards, Jaswinder. -- These are my opinions not 3Di. > -Mike > > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to [EMAIL PROTECTED] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

So why >try to force it on everyone? The other lists to which I subscribe (SAG-L and HP3000-L) don't force it on everyone. Each subscriber can turn the extra subject tags on or off whenever they please. I have them turned on, so the listserver tacks them on each message that is mailed to me. People who have this option turned off (the default) never see them. >If the above procmail filter doesn't work (untested) let me know >and I will MAKE it work. Windows users - tough luck - procmail >is open source - hire someone to port it... My employer chose Lotus Notes for our email system. All incoming messages go to a Notes server. In order to read them, I have to run a Notes client to connect to the server. As far as I know, there is no way to use another mail reader to access the Notes email database on the server. So, although I run Linux on my laptop, I have to run Notes (under wine) to access my mail. There is no way to filter on headers; in fact, the ONLY headers I can see are To, cc, and Subject. (OK, I can, after opening a message, select "Delivery Information" from a menu, and then scroll through the other headers in a four line by 50 character window; but I have to do this for each message, one at a time, after they reach my inbox. There's no way to search for text in any of these headers, either.) Even if I save the messages to disk (by "exporting" them), I still get only those three headers. I can sort the list of messages in my inbox by sender or by date, but not by subject. So I usually just read everything in FIFO order, without even looking at the subject, hitting the delete key within a couple of seconds for any message that doesn't interest me. After finishing with all the messages, I use the extra tags in the Subject line to (visually) separate the messages I want to keep and move them into separate folders for each mailing list. I always leave the lkml messages till last, because without the extra tags I have to pay special attention to keep them separate from my regular (non-mailing-list) email. As far as I'm concerned, Notes is a lousy mail client. Very little can be configured by the user. The only option for quoted replies simply appends the entire message to the bottom of the reply. (I had to cut and paste your text and add the ">" characters and the "Mike Harris wrote:" line manually.) I can't even set it to automatically forward my mail to my personal email account if I'm out of town. That requires a request to a Notes administrator to do it for me, and I have to ask him to change it back when I return. Plus, when the mail is auto-forwarded it is deleted from my Notes inbox, so if the administrator is slow about turning off auto-forwarding then I don't see any of my business email at work and have to wait until I can access my personal account from home. I haven't complained about any of this on the list until now, because I know I'm in the minority and I don't expect most people to care about my problems. But it bothered me seeing the criticism Mike Harrold has gotten for his request. Not everyone has problems because they're lazy. Some of us are boxed in by decisions that are beyond our control. For my part, if anyone can tell me a method (that doesn't require Notes administrator assistance) to get my mail, with headers intact, out of Notes and into elm or pine, I'd be ecstatic.
