- Warning: all the Serial ATA Kconfig options have been renamed. If you
blindly run `make oldconfig' you won't have any disks.
Boilerplate:
- See the `hot-fixes' directory for any important updates to this patchset.
- To fetch an -mm tree using git, use (for example)
git fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git v2.6.16-rc2-mm1
- -mm kernel commit activity can be reviewed by subscribing to the
mm-commits mailing list.
echo "subscribe mm-commits" | mail [email protected]
- If you hit a bug in -mm and it is not obvious which patch caused it, it is
most valuable if you can perform a bisection search to identify which patch
introduced the bug. Instructions for this process are at
http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt
But beware that this process takes some time (around ten rebuilds and
reboots), so consider reporting the bug first and if we cannot immediately
identify the faulty patch, then perform the bisection search.
- When reporting bugs, please try to Cc: the relevant maintainer and mailing
list on any email.
- Semi-daily snapshots of the -mm lineup are uploaded to
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
the mm-commits list.

I have problem with my keyboard. I have no error in dmesg and syslog,
but it doesn't work. I read google and try "i8042.nomux", but it didn't
help.
I enclose dmesg with "i8042.debug=1" option and my config.
Maybe I forgot something in config?

Something like the appended patch is needed for the SATA/PATA options to show
up in the menu.

Hi,
posix-timers-fix-clock_nanosleep-doesnt-return-the-remaining-time-in-compatibility-mode.patch
declares two functions with the wrong return type.
Also, posix-timers-fix-the-flags-handling-in-posix_cpu_nsleep.patch uses
'=' instead of '=='.
The attached patch fix both issues.
Regards,
Frederik

Gentoo kernels are 42 times more popular than SUSE kernels among
KLive users (a service by SUSE contractor Andrea Arcangeli that
gathers data about kernels from many users worldwide).
There are three kinds of lies: Lies, Damn Lies, and Statistics.

I'll take a closer look at this. I have tested this with allyesconfig
on 2006-08-08-00-59 mm snapshot, but now it doesn't build when
CONFIG_FB_SIS=y (CONFIG_FB_SIS=m builds fine for me).
Thanks for pointing that out.

It's easy to see that you removed too much (or too few, since the
#ifdef MODULE can be removed - there's also a similar no longer
required #ifdef MODULE in sis_main.c).

Thanks for your help.
This patch should fix this problem. Tested with CONFIG_FB_SIS=y and CONFIG_FB_SIS=m.

This is the sort of thing which should have been caught in testing, but it
wasn't, which raises questions about how well-tested the rest of it is?
Plus it will have generated compiler warnings.

transform_axes() isn't a good name for a global function.
Thankfully, it can simply made static.

This patch contains the following possible cleanups:
- make the following needlessly global function static:
- ntp_update_frequency()
- make the following needlessly global variables static:
- time_state
- time_offset
- time_constant
- time_reftime
- remove the following read-only global variable:
- time_precision
Please review which of these changes do make sense and which do conflict
with pending patches.

This patch moves the CRYPTO option to the "Cryptographic options" menu
(it was the only option directly in the toplevel menu).

This patch contains the following cleanups:
- create a menu for ATA
- replace the dependencies on ATA with an "if ATA"
as a side effect, this fixes a menu breakage due to SATA_INTEL_COMBINED
- fix a typo in the PATA_OPTIDMA prompt
- let ATA selet SCSI instead of depending on SCSI
this should make it easier for users to enable ATA (similar to USB_STORAGE)
Signed-off-by: Adrian Bunk <[email protected]>

One issue I noticed while creating this patch is that for the following
options the dependency and the prompt don't agree whether the option
is EXPERIMENTAL:
- SATA_SX4
- PATA_AMD
- PATA_HPT3X3
- PATA_SC1200

HPT3x3, SC1200 are experimental
AMD is not intended to be any more.
Thanks for spotting these.

Actually I should mark this as non-experimental too but I'll do that and
push it the proper path.

My fault I suspect - shouldn't have been && PCI originally

Acking the same issue. Applied the revert patch and my keyboard now
works. Also, it turns out that my keyboard is now the only thing that
failed to resume from S3 on my HP Nc6400, but adding "irqpoll" has fixed
that for now.
Also, to two other things I spotted with cpufreq. Running
speedstep-centrino on a Core Duo T2400 (1.83GHz) I see the
"cpuinfo_max_freq" is 1833000, but "scaling_max_freq" is fixed at 1333000,
regardless of the governor, and I cannot change it.
Also, whenever I echo anything to "scaling_governor", I get the
following kernel message:

It seems that scaling still works, but this message is a bit unnerving.

Gentoo kernels are 42 times more popular than SUSE kernels among
KLive users (a service by SUSE contractor Andrea Arcangeli that
gathers data about kernels from many users worldwide).
There are three kinds of lies: Lies, Damn Lies, and Statistics.

This makes no sense at all, because in -mm __create_workqueue doesn't
call lock_cpu_hotplug().
Are you sure this was from a tree with -mm1 applied ?

You have keyboard configured as a module in your .config but I do not
see it trying to attach to the keyboard serio port. Make sure the module
is loaded.

Can I please have dmesg of booting unpatched -rc4-mm1 with i8042.debug=1?

s390 doesn't support CONFIG_HIGHMEM. Anything that depends on it would be
dead code.

What's your autofs setup? What gets mounted on /net/bix? Is it "bix:/"?

Thanks for help.
I try this patch, keyboard works, but I have other problem. When I try:
echo "standby" > /sys/power/state
system goes to standby, but keyboard stop working and CMOS clock was
corrupted (randomize date and time e.g. Fri Feb 18 2028 13:57:43). So I
must reset computer.
I enclose dmesg with i8042.debug=1 option, config, lsmod and fragment of
syslog, when I tried standby.

To fix the CMOS clock problem please try to unset CONFIG_PM_TRACE .

You never change things by fighting the existing reality.

Works fine for me also.
Andrew, can you do the following:
cat /proc/fs/nfsfs/*
And can you try mounting "bix:/" manually to see if that exhibits the same
problem? It'd be useful to know if autofs is actually having an effect.
Also, can you do a module list and check that it's autofs4 that's being used,
and not autofs. It would be handy if we could rule out an adverse interaction
between nfs and autofs4.

But what does it actually show? Do you know where the bug is then? (I don't
know exactly how bisection works).

Thanks for help, CMOS clock works correct now. But still is problem with
keyboard after standby.

Definitely 2.6.18-rc4-mm1, and I've done a clean rebuild + removal of
all modules under /lib/modules beforehand.

I've got masses of these messages - about 100-200 per second filling my
logs. It seems that they came through as such a rate that the dmesg
buffer emptied of everything else before syslogd started.

I can try to get a full boot log later when I get home.
The interrupt counts don't actually seem to increase, I checked
/proc/interrupts several times in a row and there's no change to the
8042 interrupt counts:

I mean: bisection searching through the rc4-mm1 patch pile indicates that:
everything up to but not including git-nfs.patch: OK
add git-nfs.patch to the above: fails.
The server is running 2.6.17-rc1-mm3, if that matters. (It shouldn't:
git-nfs.patch has changed the client's behaviour).
And, as I said, this machine is running stock mostly-up-to-date FC5.

Yes it does.

It's the first time I see such a message. I can't speak for 2.6.18-rc3-mm2
because it could not suspend at all (did hang right after
"echo disk > /sys/power/state"), but it worked in earlier kernels.
I'll try with plain 2.6.18-rc4.

This patch:
simplify-update_times-avoid-jiffies-jiffies_64-aliasing-problem.patch
makes my x86_64 SMP box (dual-core Athlon 64 on an ULi-based AsRock mobo) run
_very_ slow (it would take tens of minutes to boot the box if I were as
patient as to wait for that).
Strangely enough, on a non-SMP box I have tested it on it works just fine.
Greetings,
Rafael

Do /mnt and /usr have other things mounted on them on bix? Can you dump fstab
on bix?
If so, it's possible that the server-mountpoint-crossing automounter internal
to NFS doesn't like working with autofs.

I don't mean fstab, I mean /proc/mounts.

This is worrisome. Is it reproducible? If so, reverting
futex_handle_fault-always-fails.patch and retesting would be useful.
(please kill the wordwrapping in your email client, btw).

I'd say it's something like that. Odd thing is, /mnt and /usr don't have
anything mounted on them. But they do have a local partition mounted on
subdirectories within them: /mnt/export and /usr/src.

There have been a bunch of more-important changes to this file. Please
wait until Andrew pulls from me, and resend.

Yea, I'd believe that. I'm newish to the futex code, and as I said w/
the patch I'm not 100% sure its the right fix, but it does resolve an
issue we found.
I'll take another look to see if I futzed something up or if the fix is
just incomplete, although some more familiar eyes with the code would
probably help here.

Same problem with 2.6.18-rc4. I'll try earlier -rc kernel tomorrow.

__list_add will still be dereferencing prev->next, so you should see exactly
the same gpf. Note that you're not triggering the BUG()'s here, you're hitting
some other fault just walking the list.

This seems to be specific to the ondemand governor - I just tried with
conservative, and alternating it with performance, with no problems, but
as soon as I loaded ondemand, the message appeared. It seems to fire off
the message as soon as I either set the governor to ondemand, or revert
it from ondemand to something else. But going from, eg performance to
conservative, wont give the message, even with ondemand loaded.
I wonder if this might also be related to my 1.83GHz cpu only being set
to a maximum of 1.33GHz via cpufreq? cpuinfo_max_freq is correct, but
scaling_max_freq is wrong. Though doing "cat cpuinfo_max_freq >
scaling_max_freq" has fixed it up, it should be correct already.

Not sure. I'm somewhat puzzled.
Disassembling the Code: of your oops shows that we were trying to dereference esi,
which was -1 for some bizarre reason. (my objdump really hated disassembling that
function, but I think thats my tools rather than breakage in the oops).
Question is how did that list member get to be -1 ?
One pie-in-the-sky possibility is that we've corrupted memory recently, and
this link-list manipulation just stumbled across it. Note that the last file
opened before we blew up was reading i2c. Can you try and reproduce this
(if you can reproduce it at all) without the sensors stuff loaded ?
It's a long-shot, but without further clues, I'm stabbing in the dark.

on-demand is unique in the sense that its the only governor that
creates a workqueue.

That's come up a lot lately. I'm still of the opinion that something
changed in acpi that's the explanation for this.

It was impossible to get. I set the 'init' kernel option to a dedicated
script to dump dmesg, but even that went way past the messages.
It seems however that I managed to get everything a-ok now, I just
booted with 'i8042.noaux=1' and that seemed to have resolved everything.
This lappy is proving a challenge to get perfect (but I'm getting
there!)

Fyi, that didn't increment further no matter how much i battered the

I'm suspecting it's just stack gunk. If Ben could send some more such
traces that'd clear things up. Also, turning on CONFIG_UNWIND_INFO,
CONFIG_STACK_UNWIND and perhaps CONFIG_FRAME_POINTER might give us a
cleaner backtrace.

Or cpufreq

I haven't seen this bug on previous (2006-08-08) mm snapshot. Here are new i2c patches
apple-motion-sensor-driver-kconfig-fix.patch
kill-include-linux-configh.patch - it's my patch, I'm testing it for tree days.

Aug 14 22:30:10 ltg01-fedora kernel: <6>note: thunderbird-bin[2288] exited with preempt_count 1
Is it possible that this is a problem with net stack?
Binary search will take ages - I don't know how to reproduce this bug.

KLive users (a service by SUSE contractor Andrea Arcangeli that
gathers data about kernels from many users worldwide).
There are three kinds of lies: Lies, Damn Lies, and Statistics.

This patch contains the following cleanups:
- replace the dependencies on ATA with an "if ATA"
as a side effect, this fixes a menu breakage due to SATA_INTEL_COMBINED
- fix a typo in the PATA_OPTIDMA prompt
- let ATA selet SCSI instead of depending on SCSI
this should make it easier for users to enable ATA (similar to USB_STORAGE)

Could you try pulling afresh from the NFS git tree? I've fixed up a
couple of issues in which rpc_pipefs was corrupting the dcache, as well
as a few dentry leaks that were introduced by David's
nfs_alloc_client().

Well, sort of: it sometimes works, which is better than not. I tried
about 10 times and it sometimes hangs after 'shrinking memory' or whilst
writing to the swap device. The message "eth0: trigger_send() called
with the transmitter busy" didn't appear anymore.
Note that I always have had a warning sowhere in acpi_pci_link_set during suspend:
BUG: sleeping function called from invalid context at include/asm/semaphore.h:99
I'm under the impression your patch is a workaround for my network problem.
Or must really netconsole be stopped during device_suspend ?

I tested just bare 2.6.18-rc4+git-nfs.patch to eliminate any -mm unknowns.
The problem remains.

Could you please try increasing the buffer size (using log_buf_len=xxx

I'm so sorry that my initial verification was not good enough. I'd tested only
the error cases, which I found. So I didn't catch the mistakes. It's my fault.
Therefore, I did some additional tests with the patches and the mistakes fixed.
I'll re-post the revised patch set later for confirmation.
The test cases are as follows;
- The timer tests of Open POSIX test suite ver. 1.5.1
- My initial test cases (Interrupted sleep)
and some additional test cases (Non-interrupted sleep)
My testcases is inlined at the bottom of this email.
The tested environments are as follows;
- Hardware: EM64T box
- Archtechture: x86_64(64bit)
- Base kernel: vanilla kernel 2.6.18-rc4
- Distro: FC5
- Test cases are compiled in both 32bit and 64bit
The test results;
- Posix test suite
No regression found. There are still FAILED cases but those are not
in clock_nanosleep() and not changed with or without the patches.
- My test cases
No regression found. And improved in the following cases.
o 64bit testcase && Interrupted sleep && CLOCK_PROCESS_CPUTIME_ID && !TIMER_ABSTIME
o 32bit testcase && Interrupted sleep && all clock types && !TIMER_ABSTIME
o 32bit testcase && Interruptes sleep && CLOCK_PROCESS_CPUTIME_ID && TIMER_ABSTIME
I can provide the test results if you require them.
To use the inlined, compile like this;
# gcc -lrt -lpthread -DCOMPILE_64 test.c
or
# gcc -lrt -lpthread -m32 -DCOMPILE_32 test.c
and then execute like this;
# ./a.out 2>/dev/null

Why do this? Are we going to be doing this for all subsystems?

The following two are exactly equivalent:
<-- snip -->
tristate BAR1 "bar1"
depends on FOO
tristate BAR2 "bar2"
depends on FOO
<-- snip -->
if FOO
tristate BAR1 "bar1"
tristate BAR2 "bar2"
endif
<-- snip -->
I'd say the latter is a bit better, but there's no reason to convert all
subsystems since the two forms are equivalent.
In this case, I was looking for a way to fix the breakage of the ATA
menu indentation due to SATA_INTEL_COMBINED, and this is the solution I
did choose.

Hmmm... I still can't reproduce it.
What happens if you change your /etc/exports file to:
/ *(rw,async,fsid=0)
/usr/src *(rw,async,nohide)
/mnt/export *(rw,async,nohide)
Also, does removing the "/mnt/export" line from /etc/exports mean that the
/mnt reappears in the directory listing?

Hm, suspicious ...
The swap partition is not on an LVM, is it?

This is the one the patch was meant to get rid of.

Bad. If that's 100% reproducible, could you please try to nail it down?
Please revert the "suspend_console" patch before doing this, because it turns
down all consoles altogether during the suspend. You can also use the patch
and instructions at
http://marc.theaimsgroup.com/?l=linux-acpi&m=115506915023030&q=raw
to debug device drivers' suspend/resume without really suspending.

Yes, it must. For now, the consoles are suspend-unfriendly, so to speak. ;-)

Thanks. I think I'll prepare a bigger patch to add turning off the consoles
with a config switch to disable this.

Hi,
There are two BUGs with 2.6.18-rc4-mm1 that seem related to (I did the
bisection[1]):
git-drm.patch
drm-build-fix.patch
drm-build-fixes-2.patch
allow-drm-detection-of-new-via-chipsets.patch
git-drm-build-fix.patch
Here's one of the BUGs (the second one is on the web site below).

There's only one BUG at each boot, and both alternate for no particular
reason.
The lspci, dmesg and .config can be found at:
http://fdeweerdt.free.fr/drm_bug/
Any ideas for further investigation?
Thanks,
Frederik
[1] Andrew, could it be possible to put the 'mm.patch' at the very end
or at the very beginning of the patches? It is misleading to have the
kernel change it's name in the middle of a bisection :).

Oh, my fault.
Could you retry with this patch?

I guess the above is a non-fatal DRM warning.

Is this pure 2.6.18-rc4-mm1? This configuration has unsatisfied config
options. I was wondering if you had some other patches too.

I wasn't clear: I always had this "BUG: sleeping function called ...." since one year
or more. It never prevents from suspending. Do you want me to track down what cause
this message? Here is a more complete trace:

I think I found something related to netconsole and your patch
"suspend_console/resume_console". I was booting to runlevel 1 and I was using
this script to suspend:
<=== script begin ===>
#!/bin/sh
# don't want to {fsck *and* reboot} if something goes wrong
mount -oremount,ro /
# enable write caching on HD
hdparm -W1 /dev/hd[ab]
echo 6 > /proc/sys/kernel/printk
sleep 2
echo disk > /sys/power/state
<=== script end ===>
The important point is the "sleep 2" line. If it is present, I can suspend the box.
Remove the "sleep command" and it will hang after displaying:
Stopping tasks: =====================|
Shrinking memory... done (0 pages freed)
If netconsole is disabled (ie not called from command line), I do not need this
"sleep", suspend always works.

Hmm, that's what I thought at first, but consider the second BUG (as I
said, both BUGs, the ALSA one and that one appear alternatively):

I rarely update my skeleton configs ($certain_people broke my
support-symlinked-.config patch and no two kernel builds have the same
Kconfig set anyway).
So a
yes '' | make oldconfig
is step 1.

Coincidence, I'd say.
This one looks like something horrid happened in the module dependency
chain. Heaven knows. Using ascii `tle9' as a pointer?
CONFIG_DEBUG_PAGEALLOC might tell us more.

It behaves like that with the "suspend_console/resume_console" patch or
without it?

Next thing to try: Can you do the following:
echo $((0x0200)) >/proc/sys/sunrpc/nfs_debug
ls -l /net/bix
umount /net/bix
That should print some information about the client and server setup procedure
into the kernel dmesg log which can then be captured.
If you follow that up with:
echo $((0x0201)) >/proc/sys/sunrpc/nfs_debug
ls -l /net/bix
umount /net/bix
That'll dump information from the VFS interaction also. It'll be a lot more
information, and it might overrun your dmesg buffer, hence why I'm asking you

Then do:

That's the dummy root dentry (attached to s_root) which we don't actually use
for anything.

That's the actual root of the subtree for this mount (inode 2).
> SELinux: initialized (dev 0:15, type nfs), uses genfs_contexts
I wonder if this is something to do with it. I run my testbox with SELinux
disabled since it won't boot if it's turned on (udev takes so long to run that
it gets backgrounded and then fsck tries to run, but can't find any blockdev
files). Can you try turning SELinux off (booting with selinux=0 on the kernel
command line might do it).
> NFS: nfs_update_inode(0:15/2 ct=1 info=0x6)
Update the root inode from attributes with NFS_ATTR_FATTR_V3|NFS_ATTR_FATTR.

Check MAY_EXEC on root. It all looks reasonable to this point.
> NFS: lookup(/usr)
But _why_? This is very strange. We shouldn't be looking at bix:/usr yet
because we haven't read the directory and we can't know it exists yet.
Also, why isn't there a call to nfs_fhget() for bix:/usr?
> NFS: permission(0:15/2), mask=0x3, res=0
Though it appears we do have permission to write and exec the directory (I
assume that mask=0x3 -> MAY_WRITE|MAY_EXEC), though *why* we'd be trying to do
that, I don't know.
> NFS: dentry_delete(/usr, 0)
> NFS: permission(0:15/2), mask=0x1, res=0
> NFS: permission(0:15/2), mask=0x1, res=0
Again, check MAY_EXEC on the root dir.
> NFS: lookup(/mnt)
And again: _why_? We shouldn't know about bix:/mnt either.
> NFS: permission(0:15/2), mask=0x3, res=0
Again we're asking for MAY_WRITE permission as well as MAY_EXEC.
> NFS: dentry_delete(/mnt, 0)
> NFS: nfs_update_inode(0:15/2 ct=1 info=0x6)

Check we have MAY_READ on the root dir.

And open it for reading.

Okay... read some entries from the directory.

Go through the first two, which looks fine.
> NFS: dentry_delete(/usr, 8)
And then we read bix:/usr, but don't call nfs_fhget() - which is should be
reasonable since we fetched it earlier. Note that the dentry specifies
DCACHE_REFERENCED in d_flags.
> NFS: nfs_fhget(0:15/196609 ct=1)

And this looks fine.

Then we come to stat bix:/usr, and this looks fine.
On the basis of nfs_lookup() apparently not calling nfs_fhget() for the first
lookup of /usr, can you stick a printk() at the end of nfs_lookup() (in
fs/nfs/dir.c), just before the return-statement so that it prints out the
return value. And can you make nfs_lookup() print nd->flags on entry?
I'm wondering if autofs4 is trying to create a couple of directories in the
NFS share, though I can't think why it would. Uncommenting:
/* #define DEBUG */
in fs/autofs4/autofs_i.h might also be informative.

Interesting.........................
Looks like a need to find myself a new testbox - one that can cope with both
SELinux *and* udev.
I wonder what SELinux is doing...

Yes. It appears that we've decided to release 2.6.18 with this feature.

Well it's not like it'd be a regression. That thing has been there
for over a year now at least in one form or other.

What is going on here?????????????????????????????????????????????????????
stracing the automount daemon, I see:
[pid 3803] mkdir("/net", 0555) = -1 EEXIST (File exists)
[pid 3803] stat64("/net", {st_mode=S_IFDIR|0755, st_size=0, ...}) = 0
[pid 3803] mkdir("/net/trash", 0555) = -1 EEXIST (File exists)
[pid 3803] stat64("/net/trash", {st_mode=S_IFDIR|0755, st_size=1024, ...}) = 0
[pid 3803] mkdir("/net/trash/usr", 0555) = -1 EACCES (Permission denied)
I think that would be the problem. Ian?

This tree seems to change the Makefile dependancies in the kconfig
subdirectory such that a plain compile of the kernel leads to an attempt
to build the menuconfig targets. This in turn adds a new dependancy on
the curses development libraries.

Hi Ian,
I think this is probably a problem with the automounter daemon.
What I think happens is this:
(1) I've got an NFS server (trash) with the following configuration:
[root@trash dhowells]# cat /etc/exports
/ *(rw,async)
/usr/src *(rw,async)
/mnt/export *(rw,async)
(2) I do "ls -l" on the client to use the automounter to view the root NFS
share on the machine.
(3) The automounter makes /net/trash and mounts trash:/ on it.
(4) The automount daemon asks the server what other shares it has available.
(5) For each share, the automounter attempts to create the directories on
which to mount it:
SHARE DIRECTORIES TO BE CREATED
======================= =============================================
trash:/usr/src /net/trash/usr, /net/trash/usr/src
trash:/mnt/exports /net/trash/mnt, /net/trash/mnt/exports
(6) The automount daemon issued mkdir() syscalls to create these directories,
_despite_ the fact that it is doing so in a mounted filesystem.
(7) SELinux prohibits the mkdir() syscall by refusing write permission on the
directory.
(8) An unconstructed dentry is left, which causes the "?---------" lines to
appear in the ls -l listing.
With the new internal automounting code in NFS, the automounter shouldn't
attempt to do step (4) onwards for submounts as the NFS filesystem itself will
take care of that.
And, in my opinion, it shouldn't be attempting to create directories on the
server.
However, (8) might well represent a bug in NFS.

reserved port perhaps and was denied.

sys_mkdirat() calls do_path_lookup(), which checks MAY_EXEC on the dir.

lookup_create() is called. This calls __lookup_hash(), which checks MAY_EXEC

__lookup_hash() then looks up the new dentry with intent to create:
VARIABLE VALUE
=============================== ===============================
nd->flags LOOKUP_CREATE
nd->intent.open.flags O_EXCL
nd->intent.open.create_mode weird value, even in octal
This means that nfs_lookup() considers this to be "an exclusive create" of
this node, and dispenses with the LOOKUP RPC call to the server.
| NFS: lookup(/usr)
| exlusive_create
Just to confirm that the lookup is skipped.
| <--nfs_lookup() = 00000000
We return the dentry we were given, but don't return an error. The dentry we
were given is left negative (on the assumption it's about to be created), but
does get attached to the directory.
| NFS: permission(0:18/2), mask=0x3, res=0
vfs_mkdir() calls may_create() which checks that the directory has MAY_WRITE
and MAY_EXEC permissions. This firstly calls nfs_permission, which grants
permission.

And secondly calls security_inode_permission() though which SELinux which
_denies_ permission.
| NFS: dentry_delete(/usr, 0)
vfs_mkdir() returns -ENOACCES to sys_mkdirat() which releases its hold on the
dentry, but leaves the negative dentry attached to the directory.
The negative dentry wouldn't normally be a problem, even though it's attached
to its parent directory... except for the small matter that it's subsequently
listed in a directory read operation.
However, the dcache still retains the negative dentry. I'm not sure how to
deal with this. I think nfs_lookup() _must_ contact the server and prefill
the dentry if it can. Trond?

I guess, but it's also possible that multi-entry mounts similar to those
generated by the auto.net script need mount point directories created.
The same code is used for all.
I guess that I could check if the fs is autofs4 and only mount the
mounts for directories that exist, as I do in v5. However, people may
have come to rely on this so it would be a regression, for v4 at least.
Thoughts?

Possibly an RPC ping.
That's about the only thing I do that does net connects.

I'm fairly sure there's a race in autofs for the create case. I've tried
to work a solution in the past but haven't been successful yet. In any
case autofs should not allow anyone else besides the daemon to do
anything in the autofs fs. It's been a while but I think this case leads
to a deadlock.

Surely this dentry should also be unhashed at some point.
Wouldn't that be a sensible result of the failed operation?
It wouldn't then show up in a listing and the fs should normally be able
to deal with these.

Why? The lookup op succeeded, so obviously there wasn't anything there,
right?
Note that nfs_lookup_revalidate() doesn't cause the dentry to be revalidated
because the mtime on the parent directory hasn't changed.
I'm considering having nfs_readdir_lookup() mark a negative dentry it
encounters as named in a directory listing for explicit revalidation, but I
can't call nfs_mark_for_revalidate() since I don't have an inode.
I think I'll need to add a dentry flag for this purpose.

NFS: Revalidate on readdir referring to null dentry
From: David Howells <[email protected]>
Have nfs_readdir_lookup() force dentry revalidation when it comes across a
name specified by a READDIR RPC call that corresponds to a negative dentry in
the dcache.
This can be caused by an optimisation in nfs_lookup() that causes a dentry to
be incorrectly left as negative when mkdir() or similar is aborted by SELinux
mid-procedure.
This can be triggered by mounting through autofs4 a server:/ NFS share for
which there are other exports available on that server. SELinux also has to
be turned on in enforcing mode to abort mid-flow the mkdir operation performed
by autofs4.
The problematic sequence of events is this:
(1) nfs_lookup() is called by sys_mkdirat() -> lookup_create() ->
__lookup_hash() with intent to create exclusively set in the nameidata:
nd->flags == LOOKUP_CREATE
nd->intent.open.flags == O_EXCL
(2) nfs_lookup() has an optimisation to avoid going to the server in this
case, presumably since the nfs_mkdir() op or whatever will deal with the
conflict.
(3) nfs_lookup() returns successfully, leaving the dentry in a negative state,
but attached to the parent directory.
(4) sys_mkdirat() calls vfs_mkdir() which calls may_create(). may_create()
checks that the directory has MAY_WRITE and MAY_EXEC permissions.
(5) may_create() calls nfs_permission(), which grants permission.
(6) may_create() calls security_inode_permission(), which calls SELinux, which
then _DENIES_ permission.
(7) may_create() fails, and vfs_mkdir() then fails and sys_mkdirat() then
fails (as does sys_mkdir).
_However_, the new dentry is left in the negative state, with no
consultation of the server.
(8) The parent directory is listed, and the name of the new dentry is
returned.
(9) stat on the new dentry fails (because it's negative), and "ls -l" returns
"?---------" as the file type and mode.
This fix makes step (8) cause a revalidation to occur on the dentry at the
start of step (9).

This flag is redundant. There already exist methods for determining if a
dentry needs revalidation by means of the nfs_*_verifier() functions. If
you want to force a dentry lookup upon next revalidation, then add
something like
void nfs_dentry_force_revalidate(struct inode *dir, struct dentry *dentry)
{
nfs_set_verifier(dentry, nfs_save_change_attribute(dir) - 1);
}
Better still, in the case of a negative dentry: just call d_drop().

NFS: Replace null dentries that appear in readdir's list
From: David Howells <[email protected]>
Have nfs_readdir_lookup() drop and replace any null dentry when it
that gets listed by a READDIR RPC call.
This can be caused by an optimisation in nfs_lookup() that causes a dentry to
be incorrectly left as negative when mkdir() or similar is aborted by SELinux
mid-procedure.
This can be triggered by mounting through autofs4 a server:/ NFS share for
which there are other exports available on that server. SELinux also has to
be turned on in enforcing mode to abort mid-flow the mkdir operation performed
by autofs4.
The problematic sequence of events is this:
(1) nfs_lookup() is called by sys_mkdirat() -> lookup_create() ->
__lookup_hash() with intent to create exclusively set in the nameidata:
nd->flags == LOOKUP_CREATE
nd->intent.open.flags == O_EXCL
(2) nfs_lookup() has an optimisation to avoid going to the server in this
case, presumably since the nfs_mkdir() op or whatever will deal with the
conflict.
(3) nfs_lookup() returns successfully, leaving the dentry in a negative state,
but attached to the parent directory.
(4) sys_mkdirat() calls vfs_mkdir() which calls may_create(). may_create()
checks that the directory has MAY_WRITE and MAY_EXEC permissions.

(6) may_create() calls security_inode_permission(), which calls SELinux, which
then _DENIES_ permission.
(7) may_create() fails, and vfs_mkdir() then fails and sys_mkdirat() then
fails (as does sys_mkdir).
_However_, the new dentry is left in the negative state, with no
consultation of the server.
(8) The parent directory is listed, and the name of the new dentry is
returned.
(9) stat on the new dentry fails (because it's negative), and "ls -l" returns
"?---------" as the file type and mode.
This fix makes step (8) replace the dentry looked up in steps (1) - (3).

What I see is that "make defconfig" builds _all_ *config targets -
strange...
Hmmm, why does git pick up my hostname (mars)? Have I configured
somethign wrong (not in git but my gentoo system)?

Well it could be trying to build them all for me too, but as I don't
have curses development libraries it would fail at that point. I don't
think we want it to build the ones its not using. Thats daft :).

I had to configure my local git repo:

Yes, unhashing the dentry will make it invisible but I thought your
point was that the server hadn't actually been contacted when I
suggested it before. Is that a concern?

Sigh.
Guess what? I don't see that...
After you've done the "ls -l", can you run:
cat /proc/mounts
cat /proc/fs/nfsfs/*
Before unmounting, and then can you run:
cat /proc/fs/nfsfs/*
Again afterwards?

Thou shalt Not enable no dangerous CMOS corrupting suspend debugging configs ;)
No idea whether "corrupting" the CMOS content with suspend debugging data
has any influence on the keyboard resume, though, but it could easily have.

Also, what patches do you have applied? Just the NFS patches or all the -mm

Does the same happen with the first patch I sent you (see attached)? I know
Trond doesn't like it, but it would be a useful data point if you could try
it.

NFS: Revalidate on readdir referring to null dentry
From: David Howells <[email protected]>
Have nfs_readdir_lookup() force dentry revalidation when it comes across a
name specified by a READDIR RPC call that corresponds to a negative dentry in
the dcache.
This can be caused by an optimisation in nfs_lookup() that causes a dentry to
be incorrectly left as negative when mkdir() or similar is aborted by SELinux
mid-procedure.
This can be triggered by mounting through autofs4 a server:/ NFS share for
which there are other exports available on that server. SELinux also has to
be turned on in enforcing mode to abort mid-flow the mkdir operation performed
by autofs4.
The problematic sequence of events is this:
(1) nfs_lookup() is called by sys_mkdirat() -> lookup_create() ->
__lookup_hash() with intent to create exclusively set in the nameidata:
nd->flags == LOOKUP_CREATE
nd->intent.open.flags == O_EXCL
(2) nfs_lookup() has an optimisation to avoid going to the server in this
case, presumably since the nfs_mkdir() op or whatever will deal with the
conflict.
(3) nfs_lookup() returns successfully, leaving the dentry in a negative state,
but attached to the parent directory.
(4) sys_mkdirat() calls vfs_mkdir() which calls may_create(). may_create()
checks that the directory has MAY_WRITE and MAY_EXEC permissions.
(5) may_create() calls nfs_permission(), which grants permission.
(6) may_create() calls security_inode_permission(), which calls SELinux, which
then _DENIES_ permission.
(7) may_create() fails, and vfs_mkdir() then fails and sys_mkdirat() then
fails (as does sys_mkdir).
_However_, the new dentry is left in the negative state, with no
consultation of the server.
(8) The parent directory is listed, and the name of the new dentry is
returned.
(9) stat on the new dentry fails (because it's negative), and "ls -l" returns
"?---------" as the file type and mode.
This fix makes step (8) cause a revalidation to occur on the dentry at the
start of step (9).

So I tried 2.6.18-rc4-mm1 on my opteron. (Running 64-bit)
The kernel did not boot, but went into an infinite loop of
Spurious ACK on isa0060/serio0
over and over. I have two keyboards, one attached the usual
way and another attached where a mouse usually goes.
This works fine with 2.6.18-rc2, but no longer now.
One keyboard is dead, and on the other, two of the
leds blink on and off.
Unplugging a keyboard changes the repeating message to
Spurious NAK ... instead.
Unplugging both keyboards stops the nonsense, but then - no keyboard.
This kernel also fails to mount root, a fact that is hard to see as
the stupid messages quickly scroll everything else away.
That might be something simple like the changed ATA config
or multithreaded pci probe.
There just cannot be any program "trying to access hw directly",
I don't get the root fs so I don't even have init running.

I got rid of the multithreaded PCI probe - and the root fs was
recognised again (I have both SATA and SCSI, perhaps they
were probed in wrong order)
Curiously enough, the keyboard trouble went away too. Odd.
Now posting from a working 2.6.18-rc4-mm1 (With the jiffies hotfix)
Helge Hafting
I got 2.6.18-rc4-mm1 going, and it appears that system
moves at about 3x normal speed. A software clock need 3
seconds to advance 10 seconds, for example.
Everything else seems faster too, the keyboard autorepeat,
delay loops in games, and so on.
Guess I could live with this, if it'd also compile
3x faster. :-/
This is a x86-64 kernel, with the jiffies hotfix applied.

Sounds like the same issue Gregorie Favre is dealing with.
Please send full dmesg output.
Does 2.6.18-rc4, or 2.6.18-rc3-mm2 have this issue?

Yes, this is on cifs. I should have mentioned that. Is this patch going
in anyway, or should I test it? I don't know a way of reproducing
the problem.

FWIW i looked through the x86-64 patch changes between
rc3-mm2 and rc4-mm1 and I can't find anything that would be remotely
related to the timer.
If it's confirmed to have regressed in this time it would require a binary
search to track down I think.

I wonder... I think I forgot to turn SELinux enforcing back on when testing
it. Now that I do that, I see:
BUG: Dentry c5294c08{i=0,n=mnt} still in use (1) [unmount of nfs 0:14]
------------[ cut here ]------------
kernel BUG at fs/dcache.c:611!
I think Ian's right, I think I've forgotten a dput(), though why you see the
busy inodes message and not the above bug, I'm not sure.

Ok, I think I've been blinded by the coincidence :) This may be a
combination of driver changes and a ALSA bug.

Maybe both BUGs have the same cause, but there must be some kind of race
that makes one appear before the other?

It looks like %eax is in fact a sort of "seq" string, but I couldn't
figure out why we ended with this pointer :(
There are two facts that might be of interest and that I didn't notice at first:
- modprobe segfaults while loading snd-seq-oss
- if, after getting the oops, I issue a 'find /sys', the process gets
stuck at /sys/class/sound. SysRq+t shows the following stack trace:

Shouldn't do. It should be reasonable to just continue into the rest of the
function - after all, after calling d_drop() we don't have a dentry any
more[*]...
[*] Lack of a dput() not withstanding.
I'm wondering if I actually need to discard the negative dentry I already have
since I then proceed to allocate a new one.

I have narrowed it down. 2.6.18-rc4 does not have the 3x time
problem, while mm1 have it. mm1 without the hotfix jiffies
patch is just as bad.

Or, rather, this. Have to remember to discard the old dentry if we don't need
it any more, but since we now have a suitable negative dentry, we can always
instantiate it, and save on an allocation.
I don't think this can race because the parent directory's i_mutex is held by
vfs_readdir() for the duration.

NFS: Replace null dentries that appear in readdir's list [try #2]
From: David Howells <[email protected]>
Have nfs_readdir_lookup() drop and replace any null dentry when it
that gets listed by a READDIR RPC call.
This can be caused by an optimisation in nfs_lookup() that causes a dentry to
be incorrectly left as negative when mkdir() or similar is aborted by SELinux
mid-procedure.
This can be triggered by mounting through autofs4 a server:/ NFS share for
which there are other exports available on that server. SELinux also has to
be turned on in enforcing mode to abort mid-flow the mkdir operation performed
by autofs4.
The problematic sequence of events is this:
(1) nfs_lookup() is called by sys_mkdirat() -> lookup_create() ->
__lookup_hash() with intent to create exclusively set in the nameidata:
nd->flags == LOOKUP_CREATE
nd->intent.open.flags == O_EXCL
(2) nfs_lookup() has an optimisation to avoid going to the server in this
case, presumably since the nfs_mkdir() op or whatever will deal with the
conflict.
(3) nfs_lookup() returns successfully, leaving the dentry in a negative state,
but attached to the parent directory.
(4) sys_mkdirat() calls vfs_mkdir() which calls may_create(). may_create()
checks that the directory has MAY_WRITE and MAY_EXEC permissions.
(5) may_create() calls nfs_permission(), which grants permission.
(6) may_create() calls security_inode_permission(), which calls SELinux, which
then _DENIES_ permission.
(7) may_create() fails, and vfs_mkdir() then fails and sys_mkdirat() then
fails (as does sys_mkdir).
_However_, the new dentry is left in the negative state, with no
consultation of the server.
(8) The parent directory is listed, and the name of the new dentry is
returned.
(9) stat on the new dentry fails (because it's negative), and "ls -l" returns
"?---------" as the file type and mode.
This fix makes step (8) replace the dentry looked up in steps (1) - (3).

Can you narrow it down to a specific patch in -mm?

How do I do that? Is -mm available through git somehow,
or is there some other clever way?

Get the patches directory from the ftp server and put it into the
source tree as "patches". Install quilt.
Then select a middle patch from the series file. I would start it
on the boundaries of the various groups Andrew comments first.
Then
quilt push middle-patch
compile/test
if works select new middle in partition below, otherwise above.
repeat until you narrow it down to a single patch.
If the partition is below you have to use quilt pop ... instead of quilt push
Sometimes patches don't compile on their own, but in this case
treating them as groups is ok.
Also when you hit the last patch double check it really changes
the problem by retesting with it applied again.

You can download the broken-out version of the -mm and use quilt.
Quick start:
- unpack the tarball in a directory containing vanilla 2.6.18-rc4 sources,
- rename 'broken-out' to 'patches'
- use 'quilt push n' to apply the next n patches,
- use 'quilt pop n' to revert the last n patches applied,
- 'quilt applied | wc' gives you the number of patches currently applied,
- 'quilt top' returns the name of the last patch applied.
Greetings,
Rafael

If my memory is working correctly, the CMOS and keyboard etc are all out
there on that primative (XC?) bus, off a sort of ISA spur, off the first
PCI bus? So they may be 'near' in address terms.
Anyone got one of those old diagrams?

This git tree is automatically pulled into the -mm build, so it will be
in the next -mm build. The patch causing the problem isn't in mainline
yet, so there is no rush to fix it there.

These sorts of crashes down in sysfs often are hard to diagnose. What did
the driver do to cause this? Dunno. But it continues to look like an ALSA
thing.
If you had CONFIG_PCI_MULTITHREAD_PROBE enabled, please try disabling it.

Yep, but it's hard to figure out without a crystal ball...

If the oops occurs at the manual loading of snd-seq-oss module, this
options would be hardly related. But, it's worth to try.
Frederik, what hardware are you using? Is it emu10k1?
I'm wondering how is the order of module/driver initialization.
Does this bug happens if you load snd-seq manually before snd-seq-oss?
Last but not least, is the oops avoided when you disable alsa-git
patch?

You'll find the lspci output, dmesg, .config at
http://fdeweerdt.free.fr/drm_bug/, I mentioned it previously on the
thread, but at that time I thought it was related with drm (I must have
messed up with my bisection) so you weren't CC'd, sorry.
Anyway, the relevant line in the lspci is:
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
Which uses the snd_intel8x0 module.

Err, turns up I maybe was right with the bisection. I think that the
drm patches mess my box in some way that it makes ALSA fail: I was
trying to load the modules by hand as you suggested, but the machine
rebooted instantaneously.
As I was about to retry, it occured to me that maybe this drm had
something to do after all and I tried shutting down the X server _before_
loading the ALSA modules: box freeze.
Now, the box is behaving OK (no oopses) with the DRI line commented in
the xorg.conf file. I'll try to narrow down which part of the DRM update
is causing such a strange behaviour. Sorry for the noise Takashi.

Frederik

Are you using the ata_piix driver by chance for your root partition? If
so, the multi-thread stuff will not work unless you use the hack below.

The keyboard stuff is very odd, your keyboard should not be on the PCI
bus :(

The guilty patch is:
ntp-add-ntp_update_frequency.patch
Up to and including the previous patch,
wich is ntp-move-all-the-ntp-related-code-to-ntpc-fix.patch,
everything is fine. But apply this one, and
time moves at 3x speed. This makes games interesting,
and the keyboard autorepeat awesome. :-)
The patch found seems reasonable, it is
definitely time-related.
Thanks to all who sent a tutorial on quilt bisection!

No, the root is on via sata.

No, it is almost ordinary. Almost, for I have another keyboard
still connected to the ps2 mouse port, I used to have a two-user setup.
I don't have any pci cards with keyboards connected.

The funny-looking dentries in /net/bix have gone away.
But `ls -l /net/bix/usr/src' doesn't mount bix:/usr/src.

Hi Andrew,
I think that this definitely qualifies as a drm bug. Here are the tests
that I did and that make me think so:
- Removing the line 'Load "dri"' from xorg.conf makes the oops
disappear.
- The bisection I performed indicates that the problem comes from the
following set of patches:
git-drm.patch
drm-build-fix.patch
drm-build-fixes-2.patch
allow-drm-detection-of-new-via-chipsets.patch
git-drm-build-fix.patch
- Appliying the attached patch makes the oops disapear too.
Now, I don't know the drm code, and I'm not able to explain why the fix
works... Any ideas?
Regards,
Frederik

Hi Andrew,
The following patch adds minor fixes to the drm code:
- fix return values that are wrong (return E* instead of return -E*)
- replaces an argument to a sizeof in drm_setversion to match the actual
variable name
- handle drm_set_busid() return value in drm_setversion

are you sure the callers of these don't wrap it inside a DRM_ERR()
macro ?

I changed the values when:
- I've checked what seemed right, getting back to the system call.
drm_ioctl(), through a call to func().
That's the case for:
- the EFAULT value in i915_emit_box
- two EINVAL values in drm_setversion
- the return value wasn't used. That was the case for
drm_set_busid return values, I felt having returned values negative
from the start was more consistent.
Is there a particular change that looked suspicious to you?
Thanks,
Frederik

Yes, that I believe is due to the automounter program combined with that
optimisation in the NFS client code. *readdir* fixes the falsely negative
dentry, but only if you _do_ a readdir of the parent directory, and only then
if you read enough of the directory to locate the dodgy dentry.
This is normally only a problem if SELinux aborts the mkdir operation between
calling the filesystem's lookup() op and the filesystem's mkdir() op, if the
filesystem is written - as NFS is - to assume the the lookup() op _will_ be
followed by a call to the mkdir() op whatever happens. Unfortunately, with
SELinux sticking its foot in the way, this no longer holds true, and the
initial lookup _must_ properly instantiate the dentry it is given - and that
means it must query the server in such a case.
That said, that will likely prevent autofs from being able to create arbitrary
directories if the underlying security constraints don't let it.
There is another problem with autofs arbitrarily creating directory dentries
in this manner: the automount program doesn't know whether the directory it is
creating corresponds to a directory on the server - or whether it corresponds
to a symbolic link... The server _must_ be queried.
So, I think:
(1) I have to change my patch again, and that I have to make nfs_lookup()
unconditionally query the server (comments Trond?), and
(2) Ian has to patch the automounter to not attempt to mount undermounts
automatically - with the new in-NFS-client automounting code, this should
be unnecessary, except for when the an intervening directory is
inaccessible, and I'm not sure what you can do about that (Ian? Trond?)

I guess I knew this would with the nfs v4 mounting.
I don't have a server with v4 nested type mounts handy. How can I tell,
from the output of the exports list, what I should leave alone?

Thanks for testing, it's a silly sign problem. gcc turned the divide into
an unsigned one.

This fixes my problems. Might I suggest this for the hot-fixes/

I can confirm that 2.6.18-rc4-mm2 with this fix keeps time correctly.
2.6.18-rc4-mm2 without it has the 3x time problem, and
produce the following debug output:

And NFS2 and NFS3. You just need a server that has two levels of export, one
under the other, for example:
[/etc/exports]
/ *(rw,async,fsid=0)
/usr/src *(rw,async,nohide)

These are all actual bugs , however I doubt any of the codepaths are
causing a major problem, a lot of those code paths are for older X
systems or not very likely hit, I'll pull the fixes into the DRM tree
now... the i915 one is a worry I must give out the TG/Intel folks :-)
Thanks,
Dave.

I've been busy lately so having trouble following this stuff in a timely
manner, I think this is an error path which the userpsace code doesn't
clean up properly, your patch is most definitely not correct..
if I had to guess I'd say you have an AGP machine + card but no AGP

That makes it a bit hard as the /net functionality that Andrew is using is
meant to mount all exports from the given server. In v4 that are mounted
and umounted as a unit to deal with the nesting.

The lspci output is available at http://fdeweerdt.free.fr/drm_bug,

I see. So this is most likely X's having trouble with the EFAULT on
unlock? I've gone through the 2.6.18-rc4-mm1 patches, and I couldn't
relate the updates and that new drm_unlock() error message. Any idea?

I've got CONFIG_AGP=y and CONFIG_AGP_INTEL=y, do I need some more
options? What's strange is that this worked perfectly with
2.6.18-rc3-mm2...

I agree, I just corrected those because I happen to stumble upon them.
I've tried a kernel with those corrections alone, and it didn't changed
anything on the oopses.

Why does the automounter daemon have to do the mounting of submounts? What's
wrong with having the kernel do it? The one problem with having the kernel do
it that I can see, is that the kernel doesn't update /etc/mtab.
Note that rather than manually mounting the submounts, you could just open and
close those directories as that should cause them to automount - though the
xdev mountpoints will expire and become automatically unmounted after a
certain period.

Yes with autofs version 4, because of the nesting of mounts which also
introduces issues with expiration. Its basically due to the dependencies
and the relatively simple minded way they are handled.
In version 5 they are mounted and umounted on demand.

v2 and v3 won't do the expire, will they?
Not updating the mtab will be a problem for me also and possibly for
users that expect to see mounts in it.
The "/net" functionality is a standard, expected automounter function.

The xdev (assume you mean NFSv4 submounts) mounts will be the area I need
to work on, for sure.
I don't quite understand the "open will cause the automount" for NFS
version < 4. The automounter calls mount(8) when it gets a packet from the
autofs[4] kernel module due to an access.
I expect that I won't have to do much at all for xdev mounts except to be
able to recoginize them and their owners so I can leave them alone. The
expire function might be a bit interesting.

The NFS client's automounting facilities handle automatic expiration and
implicit recursive unmounting of xdev submounts.
For example, on my test machine:
[root@andromeda ~]# /root/mount warthog:/ /warthog -o fsc
[root@andromeda ~]# ls /warthog/warthog
[root@andromeda ~]# cat /proc/mounts
...
warthog:/ /warthog nfs rw,vers=3,rsize=32768,wsize=32768,hard,fsc,proto=tcp,timeo=600,retrans=2,sec=sys,addr=warthog 0 0
warthog:/warthog /warthog/warthog nfs rw,vers=3,rsize=32768,wsize=32768,hard,fsc,proto=tcp,timeo=600,retrans=2,sec=sys,addr=warthog 0 0
[root@andromeda ~]# umount /warthog/
[root@andromeda ~]#
The "ls" command caused the client to mount warthog:/warthog off of the server
onto /warthog/warthog automatically. I was then able to just unmount
/warthog, which took away /warthog/warthog also without me having to do
anything special.

This should now be left to the NFS client.
The NFS client now views each set of files with the same FSID as a separate
collection of files, and accords each set its own superblock. The superblocks
thus created are automounted by the follow_link() op on the directory that's
at the point of FSID-change.
Note! This works for NFS2, NFS3 and NFS4. NFS4 has an extra facility by
which mounts can cross servers, but that uses more or less the same mechanism.

Yes. Automounting and auto-expiration both.

ln -sf /proc/mounts /etc/mtab

Whilst that may be true, it doesn't prohibit working with the NFS clients
automounting capabilities.

I mean NFSv2, NFSv3 and NFSv4 submounts that cross FSID, but remain on the
same server.

Opening the directory will cause its follow_link() op to be invoked, which
will cause an automount if one hasn't already happened. Obviously, if the
automount has taken place, the lower directory won't be seen for the follow to
take place.

The automounter must mount the root of any tree, yes; but xdev subtrees should
now be left to the NFS client to mount, which can be triggered by stat'ing the
mountpoint - admittedly, if you can reach it without a security error.
If you do get a security error, and attempt to build the directories anyway,
you run the risk of constructing a false image of the remote share as you
can't tell symlinks from directories, and run the risk of creating invalid
dentries locally because you can't determine the attributes of the remote
object.

They're self-expiring. And, as I mentioned above, you only need to unmount
the root to dispose of the entire tree.

Can you startup without X, do
echo 1 > /sys/modules/drm/parameters/debug
start X, and send me the dmesg output up to the oops?
Don't cc the list as I suspect it will be quite large..

Very cool.
I guess I'm not concerned about what the expire timeout is for such trees
either as it's not my problem.
I'll have to play around with these a bit to work out how I can recognize
them in the export list. Hopefully it will be straight forward.

Yep.
Again, not my problem if I treat fsid filesets as the automount unit.

Yep. But also not my problem as user activity will make this happen
automagically.

Yep. No use in stepping on NFSs toes when he just wants to make my life
easier for me.

This is going to be fun after all.
There isn't any way to tell a nohide from a non-nohide mount from the
expots list.
There are inconsistencies with the contents of /proc/mounts between OS
versions (perhaps kernel version).
There is no way to tell a nohide mounted filesystem from the output of
/proc/mounts if it does happen to appear in it.
*sigh*

Why do you care? NFS shouldn't be barfing if you try to mount the
filesystem yourself. If it does, then it is broken.

Huh? The NFS output for /proc/mounts hasn't changed.

Why do you care?

I believe that we had it fixed at one point...?
