[PATCH 0/3] rhashtable: Handle table allocation failure during insertion

[PATCH 0/3] rhashtable: Handle table allocation failure during insertion

[Herbert Xu]

Hi:

This series tackles the problem of table allocation failures during
insertion.  The issue is that we cannot vmalloc during insertion.
This series deals with this by introducing nested tables.

The first two patches removes manual hash table walks which cannot
work on a nested table.

The final patch introduces nested tables.

I've tested this with test_rhashtable and it appears to work.

Cheers,

[PATCH 1/3] gfs2: Use rhashtable walk interface in glock_hash_walk

[Herbert Xu]

The function glock_hash_walk walks the rhashtable by hand.  This
is broken because if it catches the hash table in the middle of
a rehash, then it will miss entries.

This patch replaces the manual walk by using the rhashtable walk
interface.

[PATCH 2/3] tipc: Fix tipc_sk_reinit race conditions

[Herbert Xu]

There are two problems with the function tipc_sk_reinit.  Firstly
it's doing a manual walk over an rhashtable.  This is broken as
an rhashtable can be resized and if you manually walk over it
during a resize then you may miss entries.

Secondly it's missing memory barriers as previously the code used
spinlocks which provide the barriers implicitly.

This patch fixes both problems.

[PATCH 3/3] rhashtable: Add nested tables

[Herbert Xu]

This patch adds code that handles GFP_ATOMIC kmalloc failure on
insertion.  As we cannot use vmalloc, we solve it by making our
hash table nested.  That is, we allocate single pages at each level
and reach our desired table size by nesting them.

When a nested table is created, only a single page is allocated
at the top-level.  Lower levels are allocated on demand during
insertion.  Therefore for each insertion to succeed, only two
(non-consecutive) pages are needed.

After a nested table is created, a rehash will be scheduled in
order to switch to a vmalloced table as soon as possible.  Also,
the rehash code will never rehash into a nested table.  If we
detect a nested table during a rehash, the rehash will be aborted
and a new rehash will be scheduled.

Ok, but why?

It seems to add a whole lot of complexity...

What users can't handle the insert failure case until resize
has completed?

Would relaxing the max chain length (until rehash is done) be an
alternative?

Because people expect the hash table insertion to succeed, even
on softirq paths where you cannot vmalloc.

Users that need to insert on softirq that cannot throttle the
rate.

Considering that this is intended for users that cannot throttle
the rate of insertion, I think we'd be much better off just failing
them than sticking them on what will essentially be a linked list.

As people don't like insertion failure, I think this level of
complexity is justified.

I can't really say anything here because *I* don't expect
it to succeed.

Even with this proposed patch things will eventually fail
on OOM conditions.

Also, such period should be very short until rht has reached
peak size for the workload.

I think that would depend on the user and the requirement, but
I don't know of any such users.

I get impression thatan (r)hashtable might be the wrong data
structure for this in first place.

Also, given that we could easily oversubscribe a table by a factor
of 10 or more while still keeping sane chain lengths I don't
see why thats a problem (also, a 'rht_insert_force' or similar
interface that doesn't do chain length checks makes it
easy to spot places that need/want this behaviour).

> As people don't like insertion failure, I think this level of

I am not sure.

I think rhastable is already bloated; I can't say I can understand
all of the checks and knobs it has without looking at git history.

(insecure_elasticity and/or insecure_max_entries come to mind, seems
 some of that might not even be needed anymore but I don't have time
 right now to investigate).

Think about incoming TCP connections, you can't rate-limit that
without defeating yourself.

Exactly.  That's the only case where it should fail.  Previously
it would fail if we cannot allocate a large number of consecutive
pages, which can happen even if you have lots of memory left.  With
my patch it will only fail if it cannot allocate at most two non-
consecutive pages, i.e., a real OOM.

> Also, such period should be very short until rht has reached

How would you know? The rate of insertions could be extremely
high.

But you would still have to impose a limit, whether it's 1 or
10.  IOW you will still fail insertions at some point even though
you have sufficient memory to perform the insertion.

Yes insecure_elasticity is now obsolete and anyone using it should
switch over to rhlist.  Once nobody uses it then it can be removed.

Re: [PATCH 0/3] rhashtable: Handle table allocation failure during insertion

rhashtable is indeed getting quite complex, but I understand your
motivation for doing this work.

I also agree that only true OOM situations should cause insertion
failures.

Given the delicate nature of change rhashtable this way, I'm going
to let these changes sit for a couple days before applying them.

Thanks Herbert.

No problems.  Good thing too as the lkp found a bug in my RCU
annotation.  So I will send a v2 with that fixed.

Thanks,

[v2 PATCH 0/3] rhashtable: Handle table allocation failure during insertion

[Herbert Xu]

Hi:

v2 -

Added Ack to patch 2.
Fixed RCU annotation in code path executed by rehasher by using
rht_dereference_bucket.

v1 -

This series tackles the problem of table allocation failures during
insertion.  The issue is that we cannot vmalloc during insertion.
This series deals with this by introducing nested tables.

The first two patches removes manual hash table walks which cannot
work on a nested table.

The final patch introduces nested tables.

I've tested this with test_rhashtable and it appears to work.

Cheers,

[v2 PATCH 1/3] gfs2: Use rhashtable walk interface in glock_hash_walk

[Herbert Xu]

The function glock_hash_walk walks the rhashtable by hand.  This
is broken because if it catches the hash table in the middle of
a rehash, then it will miss entries.

This patch replaces the manual walk by using the rhashtable walk
interface.

[v2 PATCH 2/3] tipc: Fix tipc_sk_reinit race conditions

[Herbert Xu]

There are two problems with the function tipc_sk_reinit.  Firstly
it's doing a manual walk over an rhashtable.  This is broken as
an rhashtable can be resized and if you manually walk over it
during a resize then you may miss entries.

Secondly it's missing memory barriers as previously the code used
spinlocks which provide the barriers implicitly.

This patch fixes both problems.

[v2 PATCH 3/3] rhashtable: Add nested tables

[Herbert Xu]

This patch adds code that handles GFP_ATOMIC kmalloc failure on
insertion.  As we cannot use vmalloc, we solve it by making our
hash table nested.  That is, we allocate single pages at each level
and reach our desired table size by nesting them.

When a nested table is created, only a single page is allocated
at the top-level.  Lower levels are allocated on demand during
insertion.  Therefore for each insertion to succeed, only two
(non-consecutive) pages are needed.

After a nested table is created, a rehash will be scheduled in
order to switch to a vmalloced table as soon as possible.  Also,
the rehash code will never rehash into a nested table.  If we
detect a nested table during a rehash, the rehash will be aborted
and a new rehash will be scheduled.
