Hey Linus,
I am not sure how to debug this but with v3.3 with just that git commit I can't
start an user space application called 'xenstored'. A bit of strace showed me:
[edit, also with todays linus/master I get the same issue, and if I revert
your patch it works again]
(right is 3.3, left is with your patch)
write(3, "Checking store complete.\n", 25) = 25 write(3, "Checking store complete.\n", 25) = 25

and if I ls /proc/xen (v3.3):

-????????? ? ? ? ? ? xsd_port
Looking at the code that sets up 'xsd_port' it looks pretty innocent
and similar to other drivers (ibmasm for example).
Also attached is the .config
Note: to actually bootup the latest with Xen there are some fixes required
to fix the regressions introduced:

No idea if it is related and haven't bisected, but we are seeing
similar ENOENT issues with things in selinuxfs. And not a single bit
of SELinux code has changed since v3.3. So it's certainly a VFS
problem. This sounds likely.

Reverting this patch also fixed the spurious ENOENT problems (and
related boot failures) from SELinux.
Easy reproducer with SELinux enabled (although might I suggest
permissive/enforcing=0 since the box can't boot otherwise):
compute_create system_u:system_r:kernel_t:s0
system_u:object_r:init_exec_t:s0 process
If you get back system_u:object_r:init_exec_t:s0 it failed and you'll
see under strace the ENOENT stat() failure.
If you get back system_u:object_r:init_t:s0 it means it worked...

Interesting... that's exactly 8 characters. Oh, I see - hash_name() gets
an extra multiplication by 9 in this case. Look: full_name_hash() will
handle the first word, decrement len by 8, set hash to <first word> and
bugger off on !len. hash_name(), OTOH, will go through the loops once,
with hash and a both 0. hash stays 0, a becomes <first word>. No NUL or
/ in it, so in we go again; hash becomes a * 9, i.e. <first word> * 9.
a becomes the second word, with mask != 0. And we are out of the loop,
and proceed to add nothing to hash (the name is over at that point). As
the result, we get hash mismatch for names that are 8 bytes long or
multiple thereof.

Unless I'm misreading that code, the problem should hit on names with
length being a multiple of 8...

OK, full_name_hash()/hash_name() definitely have a mismatch and it's on the
names of length 8*n: trivial experiment shows that we have
name hash_name full_name_hash
a 61 61
ab 6261 6261
abc 636261 636261
abcd 64636261 64636261
abcdabc 64c6c4c2 64c6c4c2
abcdabcd efcead5 c8c6c4c2
abcdabcd9 efceb0e efceb0e
Linus, which way do you prefer to shift it? Should hash_name() change to
match full_name_hash() or should it be the other way round?
What happens is that you get multiplication by 9 and adding 0 in the former,
after having added the last full word. In the latter we add the last full
word, see that there's nothing left and bugger off.

Good catch, guys.
Ugh. And I never noticed despite having run this code on my machines
for several weeks, because I don't think I have anything that uses the
"full_name_hash()" function. And it looked so obviously the same.

Yes. I think we should make things match "hash_name()", because that's
the one that is critical and we want to really generate good code for.
I think you can just move the "*=9" down in full_name_hash(), so that
we always "pre-multiply" the hash for the next round. But I'll have
to double-check my logic.

Yup, that's the patch I was thinking of too.
But I didn't test it. And considering that apparently I don't have
anything that ever triggers this, I guess I should write some
user-space harness thing for this.
I actually wrote some *other* user-space testing functions (checking
that the hash values we generated were good), but I never tested the
"unimportant and totally obvious" full_name_hash() function.
Btw, about test harnesses: I do have a patch to the kernel that
exposes the dentry hash chains through /proc. Interesting to anybody
else? I decided that I didn't want to try to simulate the dentry
hashing in user space, since part of the final hash function is the
'parent' dentry pointer itself (the name hash part is user-spaceable,
but I wanted to see the distribution of those parent bits too).

See upthread for diff doing just that ;-) Let's see if that fixes the
crap guys are seeing... BTW, you have used full_name_hash(), just not
on something 8 char long - devpts uses d_alloc_name(), but pty numbers
tend to be less than ten millions...

Moving the "*=9" down to the "next" iteration does fix it for me in my
user-space test I just whipped up. Not exhaustive, but at least the
test confirms the thinking.
But yeah, let's verify that it also fixes the actual problem being reported.
And you're right, I don't have ten million pty's ;)

Hmm... How about
Fix full_name_hash() behaviour when length is a multiple of 8
We want it to match what hash_name() is doing, which means extra
multiply by 9 in this case...
