spl's Introduction

This repo is archived. Alternate processes for contributing ZFS changes include following the illumos procedures, or opening a PR against ZFSonLinux.

The reasoning behind this are outlined in an email to the [email protected] mailing list, which is reproduced below:

The OpenZFS code repository on github (http://github.com/openzfs/openzfs) is a clone of the illumos repo, with basically identical code. The OpenZFS repo made it easier to contribute ZFS code to illumos, by leveraging the github pull request and code review processes, and by automatically building illumos and running the ZFS Test Suite.

Unfortunately, the automated systems have atrophied and we lack the effort and interest to maintain it. Meanwhile, the illumos code review and contribution process has been working well for a lot of ZFS changes (notably including ports from Linux).

Since the utility of this repo has decreased, and the volunteer workforce isn't available to maintain it, we will be archiving http://github.com/openzfs/openzfs in the coming week. Thank you to everyone who helped maintain this infrastructure, and to those who leveraged it to contribute over 500 commits to ZFS on illumos! Alternate processes for contributing ZFS changes (including those in open PR's) include following the illumos procedures, or opening a PR against ZFSonLinux.

spl's Issues

zfs mount command not working, not giving any output

Sorry, I am not too familiar with ZFS, but judging from the ZFS manual, this should work. I am trying to access the partition created with Solaris 10. I'd expect to at least see an error message.

Kernel oops with splat on userland SIGINT

I've found that I can consistently crash (oops) the module by SIG-INTing the splat userland process during the atomicity test. I presume it has to do with writing to a defunct fd (ioctl response) or with destructing the testcase state early (_fini function called early?)

This looks, however, different from the #22, which is why I attach the other (SIGINT triggered) kernel trace as well - it is quite lengthy

Alien creates wrong version debs

Currently a 'make deb' creates packages with the version '0.6.0-1'. Which is the same as I had previously :).

Alien needs the option '--keep-version' to create the correct '0.6.0-rc5'...

Apparently, the 2.6.26 kernel doesn't have functions which are required to compile and use the SPL.

I think this problem cannot be resolved by patching the spl, I think the "only" solution is to use the backport kernel, which is reported in the issue #10

What are your thoughts about it ?

SPL/head doesn't seem to build properly on Ubuntu 10.04 anymore

Just tried to get this working on a fresh install of Ubuntu 10.04/x64 inside a VirtualBox VM. "./configure && make && make install" went ok, but when I try to load the modules, I get this:

root@zfstest:# modprobe spl
FATAL: Error inserting spl (/lib/modules/2.6.32-22-server/addon/spl/spl/spl.ko): Cannot assign requested address
root@zfstest:# modprobe splat
FATAL: Error inserting splat (/lib/modules/2.6.32-22-server/addon/spl/splat/splat.ko): Cannot assign requested address

No useful output in dmesg, not sure how further to debug.

name conflict with the SPL programming language

The libspl.a file provided by the Solaris Porting Layer conflicts with the spl-dev package that is already in Debian and Ubuntu:

In pkg-spl, this causes a package conflict that requires a lint override.

Consider renaming libspl to libzspl so that it does not conflict with any other software that is already in regular distribution.

utsrelease.h

Hey,
Just a heads up, as of at least 2.6.33 utsrelease.h moved from $kernelbuild/include/linux/utsrelease.h TO $kernelbuild/include/generated/utsrelease.h

Just found that out the hard way when it wouldn't configure with the new kernel.

Hope it helps,

SPL can not build on 2.6.39 kernel

I try to compile zfs+spl on Jeremy's kernel 2.6.39-rc3 and receive error:

/tmp/spl-build-root-keyAkN9Q/BUILD/spl-0.6.0/module/spl/../../module/spl/spl-vnode.c:42: error: ‘SPIN_LOCK_UNLOCKED’ undeclared here (not in a function)

As I see in kernel header file linux/spinlock_types.h, SPIN_LOCK_UNLOCKED was deprecated already in 2.6.32 and now in 2.6.39 no such definition exist.

How to install on Ubuntu 10.04

Just a guide for others (newbies). Also if I'm doing something wrong please let me know. This is a guide for how to install SPL on Ubuntu or other Debian based systems.

Make sure you have Automake, alien, splat and rpm installed:
sudo apt-get install automake rpm alien splat
Download and extract the source code to /usr/src (could be anywhere)
Go to folder in terminal and run
./configure
If you see any errors, it will most likely be due to a package you are missing. Install it with the same command as above.
Make the rpm
make rpm
You should see 3 *x86_64.rpm files. Install them all one by one using alien (replace filename with the name of the file)
sudo alien -i filename

Note: When I try to convert the .rpm into a .deb I get errors, so I just went with this.

Run tests using splat, first you have to enable it
sudo modprobe splat
sudo splat -a

Every test must pass.

Hopes this helps someone.

ZFS causing segmentation faults and crashing the system.

I have been try to figure out what is going on with my system I have had ZFS running for a while with no issue but for some reason it will let me read ~700MB and then throws a segmentation fault and crashes the system.

This has been happening for about a week. I rebooted it today and now ZFS will simply not load.

Not sure how much of these call traces are useful but here is the one which does not allow ZFS to load at all. If you need the others just let me know and I will post them.

I'm using Ubuntu 11.04 Server. 8GB of RAM and AMD Phenom 8450e

Add taskq TQ_FRONT flag

The taskq API need to be extended to support the TQ_FRONT flag. This is going to be slightly more complicated than simply adding the work item to the head of the list. The current implementation relies on the fact that all work items are added to the end of the list thus maintaining an ordered list of taskq_ids for lowest to highest. Simply placing new items at the list head will break this ordering resulting in incorrect semantics for taskq_wait{_id}().

The right way to handle this I think will be to add another high priority list of just these items which is always consumed first. This preserves the previous ordering which is important because we never want to traverse the entire pending list which may contain 1000's of entries. The taskq_wait{_id}() functions and logic for getting the next work item will need to be updated to handle this.

Finally, a splat regression test must be carefully crafted to test this flag and ensure it is behaving properly. This will ensure we got it right and we will notice a regression.

support for recent stable kernels needed.

Spl rely on ctl_name in the ctl_table structure in include/linux/sysctl.h which is eliminated starting from 2.6.33 stable (commit 86926d0096279b9739ceeff40f68d3c33b9119a9).
It does not check if linux kernel has fix for O_DSYNC flag, which was introduced by commit 6b2f3d1f769be5779b479c37800229d9a4809fc3.
On Fedora 13, with kernel 2.6.33.3-85.fc13 after fixing these 2 problems I run into next one:
{{{

I don't know how to fix it.

System hang

I have been experiencing frequent total system hangs whilst using 0.6.0 RCs. Below is all I can find related to it in the kernel logs:
Is there somewhere else I should be looking too?

It's a Debian 5.0 "Lenny", with all the tools needed for compilation.

Thank you.

XDR Regression Tests

The XDR implementation currently does not have any regression tests as part of the SPLAT test framework. While I'm not aware of any issues with the XDR code we do need to add some regression tests to make sure nothing gets accidentally broken.

Taskq locking optimization

Recent oprofile results suggest that the tq->tq_lock can be highly contended on 16-core when your attempting perform a large number of small work items. This results in a significant impact to taskq throughput at lots of wasted cpu cycles, 19% according to oprofile. Additionally, this lock has to disable interrupts so there may be wide spread performance implications. This appears to be much less of an issue on smaller SMP systems.

To address this issue we need to look in to refactoring the taskq code to minimize the length of time this lock is held. Currently this single lock protects everything is the taskq structure all the values, flags, list heads, and wait queues. This was done to keep the implementation simple but we could benefit from finer grained locking and clever use of atomic types.

Fundamentally, the only the pending and priority lists need to be protected by a spin_lock_irqsave which disables interrupts. This is done to ensure that while one of the taskq threads is dequeuing a request with the lock held, we never service an interrupt which dispatched a new item to the same taskq. This would lead to a deadlock. If we can minimize what need to be locked in taskq_dispatch() say by making it atomic, or using per-cpu data structures, we can then minimize the need to use spin_lock_irqsave().

In fact as of 2.6.36 we can take advantage of some new kernel infrastructure. It's in this release that concurrency managed work queues (cmwq) first appear and they perform a very similar function to taskq. So much so that it appears we should be able to layer the taskq API on top of cmwqs. This has a lot of advantages including keeping the kernel thread count to a minimum. The previous workqueues were not used for the taskq's because the API was for to limited, incidentally the kernel developers decided the same thing which is why we now have cmwq's.

Anyway, that's great for folks running bleeding edge kernels but we may still want to look in to optimizing the existing taskq implementation. This support is so new it likely won't be appearing in things like RHEL6 which is what we'll likely be using.

Disabled rw_tryupgrade() for newer kernels

VERIFY(rc = rw_tryenter_locked(SEM(&dn->dn_struct_rwlock))) failed
SPLError: 24204:0:(dnode.c:923:dnode_new_blkid()) SBUG

For kernels using the CONFIG_RWSEM_GENERIC_SPINLOCK implementation everything is fine. But if your kernel is building with the arch specific rwsems then rw_tryupgrade() has been disabled until it can be implemented correctly. In particular, the x86 implementation now leverages atomic primitives for serialization rather than spinlocks. So to get this working again it will need to be implemented as a cmpxchg for x86 and likely something similar for other arches we are interested in. For now it's safest to simply disable it.

SPL module does not build on rt patchset

There is a great patchset around for the kernel, called the "real-time" patchset.

Unfortunately, the SPL module does not seem compatible with this patchset.

I'm getting the following error when doing a "make deb" on 3.0.0-1-rt-amd64:

utsrelease.h

Hey,
Just a heads up, as of at least 2.6.33 utsrelease.h moved from $kernelbuild/include/linux/utsrelease.h TO $kernelbuild/include/generated/utsrelease.h

Just found that out the hard way when it wouldn't configure with the new kernel.

Hope it helps,

Can not build SPL on Debian (alpha platform) with 2.6.36.1 kernel

I am trying to build SPL on my Debian (squeeze/sid) running on alpha (COMPAQ AlphaServer DS20E) platform with kernel 2.6.36.1
I have downloaded the following source:

$ git branch -v
* master b6bd75f Some of the files were not getting compiled after merge. Added them in the module/spl/Makefile.in  and exported a symbol.

I started to compile it, however the compilation is failing with the following error:

In file included from include/linux/sched.h:87,

Honor KM_PUSHPAGE

The current kmem_cache implementation does not fully honor KM_PUSHPAGE. At the moment using KM_PUSHPAGE in you kmem_cache_alloc() call only has the effect of setting __GFP_HIGH which allows the use of reserved memory. Really this doesn't go far enough, we need the SPL to maintain it's own reserved objects on the slab which can be used when KM_PUSHPAGE is requested and all other slab objects have been exhausted. This will allow us to service the request without having to vmalloc() a new slab. The caller is then responsible for quickly returning the object to the slab to ensure forward progress can always be made.

The ZFS code makes careful use of the KM_PUSHPAGE flag to avoid deadlocks in zio pipeline. It's possible that a KM_SLEEP allocation in the zio pipeline with trigger memory reclaim, which may trigger IO to be flushed to disk, this IO will then cause a deadlock which prevents the current txg from syncing.

Add kmem cache defragmentation API

There are now consumers of the kmem cache defragmentation API, as such we should fully implement it. Basically, this will involve implementing the kmem_cache_set_move() API function to register the move callback for the slab. Then there going to need to be a few new data structure to track this. Finally, we will need to safely add all the hooks to the existing slab code to ensure it is called appropriately and the returns code are honors. Now this is going to be a little trickier than it sounds since the slab implementation is fair complicated any racy, but it does need to be done at some point. We absolutely will need to add several regression tests to make sure we got it right.

See commit 2b35430.

atomic 64bit test failing on Ubuntu 10.04 LTS i686

No problem installing spl/splat :)

The (regression) test suite fails the following testcase:

./splat -v -t 0x0b00:0x0b01

The output is nondeterministic (with the values initially veering of to the positive or the negative side of the initial value 10000000). I'm not sure what is supposed to happen, but I reckoned I'd report it first.

This is on

Hey, i hope this is not a duplicate of #27. Unfortunately i have no clue about debugging c-problems ;-)
The system is debian testing with 2.6.38-2-amd64. Furthermore i'm running 0.6.0-RC4.

strange mouse/keyboard issue in Ubuntu10.04-X86 in VirtualBox.

when i finished these:

./configure
./make rpm
alien *.rpm

although the tests of "scripts/check.sh" show all "pass".

but when i login into the ubuntu again, the mouse/keyboard does not work anymore.
(ps, i installed the advanced tool of virtualbox for ubuntu)

thanks very much.

SPL on Gentoo

Hi!

I was able to compile SPL on two different Gentoo machines using different versions of gcc and the kernel.

Machine A: GCC-4.4.3 and 2.6.33
Machine B: GCC-4.5.0 and 2.6.34 (yeah i know but i like to live a bit dangerous and i know how to help myself i shoot myself in the foot ;) )

First of all I was waiting for someone to step up and think of a way to get ZFS into my beloved linux. Nothing against (Open-)Solaris but i still prefer linux and to be honest i'm not a big fan of fuse so i really hope that you are able to introduce at least a partial working NATIVE zfs into the linux world.

So now let's get back to business: I was able to compile seriv's fork and patched version of spl (commit d7d332c6fbefa2369ea2) without touching the code with Machine A; on Machine B on the other hand i had to touch the code myself to make it compile the same version with gcc-4.5.0. The kernel itself is not the problem the problem is the stricter error-checking of gcc-4.5.0. This is the unified diff of my changes to the source-code

                rw_exit(&rwp->rw_rwlock);
        } else {

Without these changes compilation failed with this error message:

cc1: warnings being treated as errors
/root/zfs/spl/module/splat/splat-rwlock.c: In function 'splat_rwlock_test4_func':
/root/zfs/spl/module/splat/splat-rwlock.c:432:6: error: case value '1' not in enumerated type 'krw_type_t'

After compiling the kernel-modules i tried to load them but i got the following error message on both machines:

Error: Unknown symbol get_zone_counts
SPL: Failed to Load Solaris Porting Layer v0.4.9, rc = -14

I tried to find out how/if i can force spl to export this symbol but i wasn't able to find the correct option to enable it.

Anyway keep up the good work!

splat -a "BUG: scheduling while atomic"

Errors when trying to compile against 2.6.36

Could please provide patches/updates inorder to be able to compile against 2.6.36 kernels as well (maybe there're similar issues in the zfs tree too).

Building spl

I am unable to insert the kernel module. I get this in dmesg:

spl: version magic '2.6.18-194.17.1.el5 SMP mod_unload gcc-4.4' should be '2.6.18-194.17.1.el5 SMP mod_unload gcc-4.1'
