[00:07:23] *** Kelzier <Kelzier!~duka@77.105.20.26> has quit IRC (Read error: Connection reset by peer)
[00:07:31] <danmcd> Well, look at that.
[00:07:47] *** Kelzier <Kelzier!~duka@77.105.20.26> has joined #illumos
[00:07:49] <danmcd> The other question is trickier... do you break any apps with this change?
[00:08:11] <nbjoerg> hopefully everything depending on this has been fixed 20 years ago
[00:08:12] <danmcd> Remember --> we're mild slaves to autoconf making assumptions that cover both us and Oracle Solaris.
[00:08:27] <danmcd> autoconf is ubitquitous poison.
[00:08:45] <danmcd> Many modernization changes have been held up because of this. It's a point of some contention here.
[00:08:53] <nbjoerg> I know
[00:09:03] <rmustacc> Aram: Well that change isn't in illumos yet, so I thought you were asking about it by calling it out.
[00:09:08] <nbjoerg> to be fair, it is still better than 80% of the replacements when used properly
[00:09:42] <jbk> that's a pretty big qualification though :)
[00:09:54] *** gila <gila!~textual@5ED4FE92.cm-7-5d.dynamic.ziggo.nl> has quit IRC (Ping timeout: 246 seconds)
[00:09:58] <rmustacc> nbjoerg: What exactly are you looking from from me?
[00:10:12] <Aram> rmustacc: not really, only the message text is the same, the problem has been different.
[00:10:23] <nbjoerg> rmustacc: a reviewer or whatever the process demands
[00:10:23] <Aram> but of course, when I saw the bug first, I didn't know that.
[00:10:28] <Aram> in the end, it was unrelated.
[00:10:43] <nbjoerg> this is my first try at getting something anywhere near a Solarisish kernel :)
[00:10:50] <rmustacc> nbjoerg: Ah, well, see this: https://www.illumos.org/books/dev/workflow.html#from-build-to-integration
[00:11:00] <rmustacc> Past me wrote up what to do in an attempt to help.
[00:11:00] <Aram> rmustacc: in any case, I wanted your help to debug it, but I fixed it. sort ot.
[00:11:03] <Aram> s/ot/of/
[00:11:07] <rmustacc> Aram: Gotcha.
[00:11:54] *** esproul <esproul!~Adium@static-108-48-124-82.washdc.fios.verizon.net> has quit IRC (Quit: Leaving.)
[00:12:45] <danmcd> nbjoerg: The code changes themselves look simple and clean enough. It's the *testing* that people are going to ask about.
[00:12:48] <rmustacc> nbjoerg: Not particularly familiar with that part of the stack.
[00:13:00] <danmcd> I am, fortunately.
[00:13:40] <danmcd> IPv6 already has a non-broadcast model. (BTW, which BSD threw out all-0s broadcast?)
[00:13:45] <nbjoerg> ok
[00:14:12] <nbjoerg> danmcd: 4.2BSD was the last version that used them, IIRC
[00:14:24] <nbjoerg> danmcd: after that, it was all-1s everywhere, IIRC
[00:14:52] <danmcd> Really? I swear 4.4 had them (even if they were not encouraged).
[00:15:03] <nbjoerg> oh, they continued to work for a long time
[00:15:29] <nbjoerg> I think all BSDs have an option for supporting it
[00:15:33] *** mmlb <mmlb!~mmlb@73.204.130.122> has quit IRC (Ping timeout: 240 seconds)
[00:15:39] <danmcd> That's my point... people have expected them both for a long time.
[00:15:41] <nbjoerg> for netbsd, we finally changed the default recently :)
[00:15:58] <nbjoerg> on the other hand, windows by default does *not* support them
[00:16:02] <danmcd> Exactly.. So NetBSD got rid of 0's broadcast. What about Free or Open?
[00:16:13] <nbjoerg> still optional, I think
[00:16:21] <danmcd> I never used windows, but I'll trust you.
[00:16:43] <danmcd> MacOSX still has all-0s broadcast support, BTW.
[00:16:50] <nbjoerg> easiest way to test is to see if a ping for all-zero results in an arp lookup
[00:17:11] <nbjoerg> yeah, but noone (sane) uses apple as server
[00:17:20] <nbjoerg> and that's where bean counting matters :)
[00:17:22] <danmcd> Fair enough.
[00:17:43] <nbjoerg> making it an option certainly is not a bad idea
[00:17:47] <danmcd> I can imagine Joyent benefitting from that, assuming their networking backbone HW works.
[00:17:55] <danmcd> Yes, an ipadm(1M) tunable would be ideal.
[00:18:26] <nbjoerg> ipadm is likely too late?
[00:21:41] <danmcd> No...
[00:23:19] *** mmlb <mmlb!~mmlb@73.204.130.122> has joined #illumos
[00:25:08] <nbjoerg> well, it would be somewhat messy to remove the broadcasts afterwards
[00:25:09] *** Kelzier <Kelzier!~duka@77.105.20.26> has quit IRC (Ping timeout: 258 seconds)
[00:28:28] <danmcd> Not if you just unplumb/replumb. ipadm is more than capable of doing this, IIRC.
[00:28:52] <nbjoerg> yeah, but that is painful when using smartos :)
[00:29:02] <danmcd> True...
[00:29:13] <danmcd> Dinnertime US/Eastern. I gotta run. I'll watch this bug, nbjoerg.

[01:03:06] *** adulteratedjedi <adulteratedjedi!~adulterat@host86-132-140-89.range86-132.btcentralplus.com> has quit IRC (Ping timeout: 246 seconds)
[01:03:16] <Aram> rmustacc: the code is mostly POC right now... but with it, mdb is as useful to Go as it is to C, more or less.
[01:03:55] <Aram> unfortunately typed function params in DTrace will not work.
[01:04:02] <rmustacc> Why's that?
[01:04:29] <Aram> because the Go calling convention is different and DTrace (or mdb) doesn't know where to look for arguments.
[01:04:49] <rmustacc> Ah, okay. Not that DTrace isn't finding the types, but that it can't find the arguments.
[01:04:57] <Aram> yes.
[01:05:13] <rmustacc> Yeah, that's a problem I've been thinking about.
[01:05:14] <Aram> for sparc I have a hack that more or less makes this work in mdb, albeit not dtrace.
[01:05:37] <Aram> since Go is caller save I can just copy the params from the stack to register, in function preamble.
[01:05:49] <Aram> then $C will display correct parameters.
[01:06:08] <Aram> but of course DTrace trap happens before the preamble.
[01:06:13] <Aram> so this is not useful.
[01:06:52] <rmustacc> Right, the thing I was thinking about was having go admit to its abi somehow in an elf header and somehow leveraging that in DTrace.
[01:07:51] <Aram> One can get params like (on sparc):
[01:07:51] <Aram> #define goarg0 *(long long*)copyin(uregs[R_O6]+0x7ff+176+0, 8)
[01:07:51] <Aram> #define goarg1 *(long long*)copyin(uregs[R_O6]+0x7ff+176+8, 8)
[01:07:51] <Aram> but then you don't get automatic types. and you have to write all that.
[01:08:32] <Aram> well DTraca can presumaby look into using the DWARF that describes where the parameters are.
[01:08:35] <Aram> DTrace.
[01:08:51] <rmustacc> Well, the DWARF VM in the kernel is probably going to be terrible.
[01:09:42] <Aram> well you don't have to execute the code, simply scanning it suffices since the code is trivial. and it can be in userspace.
[01:12:42] <Aram> I can do the register-copy hack in the caller instead of callee. it's much harder though, but then both dtrace and mdb will just work.
[01:12:48] <Aram> but that will never fly upstream.
[01:15:05] <Aram> I could also change the calling convention but that would take a lot of technical effort and lot of convincing.
[01:17:00] *** andy_js <andy_js!~andy@94.9.28.249> has quit IRC (Quit: andy_js)
[01:20:45] <rmustacc> Yeah, it's unfortuante it can't just honor the system's abi. Would simplify a lot. :/
[01:20:56] <rmustacc> But that ship has probably sailed.
[01:21:38] <Aram> well we have done various changes to the calling convention over the years.
[01:21:43] <Aram> so it's not set in stone.
[01:21:54] <Aram> but convincing others to do this would be difficult.
[01:22:38] <Aram> it would have to coincide with another unavoidable breaking change, since this would break all assembly.
[01:23:30] <Aram> unfortunately (?) the linux tracing tools are starting to use DWARF, so this does not help us really.
[01:25:34] <richlowe> you wouldn't need the DWARF VM
[01:25:37] <richlowe> you just need type information.
[01:25:50] <richlowe> (for what we use CTF for)
[01:26:07] <richlowe> support for the bytecode language would be to avoid save-args
[01:26:29] <richlowe> which isn't to say that that subset of dwarf in the kernel would be _easy_, but it's considerably more tractable/less a bad idea.
[01:26:30] <Aram> well in the most general case, to find function arguments, you need VM.
[01:26:41] <richlowe> right, CTF can't do that. :)
[01:26:52] <Aram> sure it can? :).
[01:27:32] <richlowe> we expect arguments on the stack in a way we know where to find and/or you to follow the SysV ABI
[01:27:45] <Aram> ah, yes, sure.
[01:28:14] <richlowe> but just describing types using DWARF rather than CTF would be "easy".
[01:28:44] <Aram> yeah, it would not be hard.
[01:28:57] <richlowe> though I think a downside is that in some respects, the CTF toolchain isolates us from compilers losing their damn minds.
[01:29:14] <richlowe> whereas if our tools spoke DWARF directly, we'd have to be considerably more carefully resilient of terrible compilers with crazy ideas.
[01:29:39] <richlowe> or whatever they call SUNWspro these days.
[01:29:56] *** nbjoerg <nbjoerg!~joerg@netbsd/developer/joerg> has quit IRC (Ping timeout: 258 seconds)
[01:31:33] <richlowe> that also limits the only real advantage (to us) of using DWARF, as compared to rmustacc's various CTF-everywhere efforts.
[01:32:48] <richlowe> (also, the fact rmustacc is willing to do such things, and I'm not helps) :)
[01:34:05] <rmustacc> It is problematic that most folks are unwilling to ship their dwarf still.
[01:34:14] <rmustacc> Or when you try, start complaining that it's too large.
[01:34:18] <rmustacc> And then missing from core dumps, etc.
[01:34:28] <rmustacc> Maybe dwarf4 will be amazing, but hard to say.
[01:35:17] <Aram> I think go will hit the 32k type limit of ctf.
[01:35:40] *** carlomagno <carlomagno!~cmagno@inet-hqmc08-o.oracle.com> has joined #illumos
[01:36:03] <rmustacc> Are you emitting multiple dies?
[01:36:12] <rmustacc> Or rather converting multiple dies?
[01:36:19] <Aram> I am not converting anything.
[01:36:28] <Aram> I am generating ctf nativelly, so to speak.
[01:36:52] <Aram> there is no dwarf involved in the process.
[01:37:10] <Aram> rather, the process sort of mirrors the process of dwarf generation in the go linker.
[01:37:33] <rmustacc> Right, so I presume the dwarf generation in the linker generates a die per input object.
[01:37:49] <rmustacc> Rather than pretending it's going to merge and uniquify?
[01:37:59] <richlowe> rmustacc: I keep meaning to implement the dwarf-in-separate-files stuff in ld.
[01:38:13] <richlowe> rmustacc: and seriously considering a strip-y option that removes the bytecode but not the type descriptions.
[01:38:19] <richlowe> since that's where most of the potentially horrible sizes are
[01:38:33] <richlowe> not that that'll convince people to use -g, and never use strip
[01:38:45] <richlowe> honestly, the binutils strip has done far more for us convincing people not to use it :)
[01:40:12] <Aram> the architecture is very different, hard to speak of input objects. for all practical purposes, this works as if there was a single input objects.
[01:40:29] <Aram> a.i. everythign is packaged as a single compilation unit.
[01:41:30] *** rmesta <rmesta!~rmesta@cpe-70-114-131-66.austin.res.rr.com> has quit IRC (Quit: Leaving.)
[01:41:37] <Aram> (if you use external linking, there indeed is a single object passed to the external linker).
[01:43:42] <Aram> and there are many types even in simple go programs.

[14:51:45] <Aram> ugh, so if I set .SUNW_ctf's sh_link to point to .symtab in my object file, Solaris ld will respect this association and preserve it in the final executable.
[14:51:48] <Aram> but.
[14:51:50] <Aram> GNU ld won't.
[14:52:14] <Aram> which is bad since now I am forced to cross-compile for the moment.
[14:52:25] <Aram> any workarounds (including linker script or whatever).
[14:53:16] <Aram> or anyone know what is wrong with GNU ld? I mean, it should do this, no?

[19:05:25] <igork> hi all, can someone try to check on latest illumos - https://www.illumos.org/issues/7026
[19:06:21] <igork> i have tested in on kvm vm with custom smartos build on smartos host
[19:06:34] <Woodstock> igork: what happens if you use a different name than testpool for the 1st pool?
[19:06:34] <igork> i have 4 virtio drives on kvm vm
[19:06:56] <igork> i didn't test another pool name - i try to look zfs tests
[19:07:26] <Woodstock> try it again
[19:07:35] <Woodstock> create foopool and barpool, with the same devices
[19:07:36] <igork> Woodstock: https://paste.ec/paste/Mq4Ef-GO#aeHKLCY6FWrb6KOruUUrolRetRU7D-7LFBDV7jTMeFL
[19:07:49] <igork> it is another test
[19:07:49] <Woodstock> the error message doesn't really look like it has anything to do with the pool name
[19:08:05] <Woodstock> more like there is some confusion what c3t0d0 and c4t0d0 are
[19:08:07] <igork> where tespool.123 and testpool1.123 was tries
[19:08:21] <igork> no confusion
[19:08:36] <igork> they are different drives
[19:08:45] <Woodstock> please try "zpool create foopool c4t0d0 && zpool create barpool c3t0d0" and tell me what happens
[19:08:47] <igork> and i can create mirror on it

[19:13:14] <igork> :)
[19:13:25] <igork> ok - what will be correct synopsis ?
[19:13:26] <Woodstock> i would start with ls -l /dev/*dsk/c[34]t0d0*

[19:15:54] <Woodstock> next i would suggest you look at prtconf -Dv output to find the devids of your blkdev devices
[19:15:57] <igork> huh - i see
[19:16:05] <Woodstock> maybe there is a simpler way than prtconf, but i don't know it
[19:16:15] <Woodstock> but i could imagine that they are all the same
[19:16:36] <igork> i have no found c3t0d0
[19:16:43] <Woodstock> thats definitely not the problem
[19:16:44] <igork> interest
[19:17:06] <Woodstock> can you please check the devids?
[19:17:37] <igork> how?
[19:17:42] <Woodstock> prtconf -Dv
[19:17:51] <Woodstock> then look for a devid property on the blkdevs
[19:18:14] <igork> prtconf -dD - https://paste.ec/paste/s+TBP7s8#44o8SneGulEyEyOy8qrMt2oHWdtiiakT6Ny571lmj++
[19:18:18] <igork> will see -Dv
[19:18:37] <igork> but i see it by -dD
[19:18:50] <igork> we can see 4 vioblk
[19:19:20] <igork> with correct addresses
[19:19:46] <Woodstock> there is a reason why i asked for -Dv
[19:19:52] <igork> ok
[19:19:57] <Woodstock> so please, look at the prtconf -Dv output
[19:20:06] <Woodstock> and find the devid properties of the virtio blkdevs

[19:24:53] <Woodstock> id1,kdev@A~~~~~~~~~~~~~~~~~~~~
[19:25:04] <igork> Woodstock: you think we have issue in blkdev ?
[19:25:08] <Woodstock> so thats your problem. as such your bug synopsis should be "virtio should create unique devids"
[19:25:23] <Woodstock> that is, s/virtio/vioblk/
[19:25:40] <igork> huh
[19:26:12] <igork> cool - we have found issue in blkdev by zfs tests on kvm vm with virtio drives!
[19:26:28] <Woodstock> it's actually an issue in vioblk, not blkdev
[19:26:46] <igork> vioblk, sorry
[19:27:02] <Woodstock> will you try to fix it yourself?
[19:27:07] <igork> can you update bug?
[19:27:20] <igork> nope - i'd like if you can fix it
[19:27:27] <igork> and i can check/test it
[19:27:32] <igork> on my env with zfs tests
[19:28:23] <igork> i'm working on some zfs changes upstream from delphix tree and try to fix current one - not in my list
[19:29:34] <Woodstock> actually i'm not sure it's so trivial to fix
[19:29:42] <igork> ok
[19:29:47] <Woodstock> but what you can do is to pass unique serial numbers to qemu for each of your block devices
[19:30:17] <igork> o cam try to switch to use ide or scsi instead of virtio at this moment
[19:30:23] <Woodstock> for my kvm instances i use zvols and generate the serial numbers from the "creation" property
[19:30:34] <Woodstock> just adding the serial numbers should fix it
[19:30:39] <igork> could you paste your example?
[19:30:50] <igork> i can try fix it
[19:31:21] <igork> are you using smartos with kvm?
[19:31:42] <igork> vmadm get <id> will be fine
[19:32:28] <Woodstock> i don't use smartos, so no vmadm

[19:57:59] <LeftWing> I don't imagine it's a completely simple change.
[19:58:32] <LeftWing> I imagine some operating systems (like ours) could become confused if the devid for a device changes.
[19:58:47] <LeftWing> (Or whatever their notion of unique drive identification is)
[19:59:14] <LeftWing> There's also the challenge of what to do about image management -- i.e. making new VMs from clones of existing ones.
[19:59:18] *** merzo <merzo!~merzo@user-94-45-58-141.skif.com.ua> has quit IRC (Ping timeout: 258 seconds)
[19:59:54] <LeftWing> If a VM had a ZFS root, and we cloned it but gave it a new "serial", would that prevent it from booting in the clone?
[20:00:04] <Woodstock> i have no idea :)
[20:00:53] <Woodstock> i would expect the serial should stay the same in a clone, which likely means you cannot use the creation property as i do in my kvm script
[20:02:15] <Woodstock> and i don't think you want to add the serial to existing VMs, so setting it would probably be optional or for new VMs only
[20:02:32] <LeftWing> Right.
[20:02:41] <Woodstock> but then i have used smartos only briefly and don't know a lot about it :)
[20:04:27] <Woodstock> fixing 7026 properly could be an issue for anyone already running illumos in kvm with vioblk, as the devids would certainly change

[20:09:14] <danmcd> NP. Shit keeps popping up. Whether it's a latent bug that a bugfix fixed (yes say that three times fast), or finding out I'm still mildly blocked on an external dependency.
[20:09:42] <igork> another issue - if you have virtio disk on VM and change it to use IDE - you can't boot
[20:09:46] <danmcd> And the latent bug that a bugfix fixed is an omnios-build one. The mild blocking is on upstream -gate.
[20:09:51] <richlowe> that doesn't sound unexpected.
[20:10:48] <daleg> stupid question out of curiosity
[20:10:59] <richlowe> stupid answer, sarcastically.
[20:11:28] <daleg> given modern hardware, what are the use cases for non-MSI-X interrupt processing in a driver? (eg, legacy or MSI)
[20:12:20] <richlowe> with modern hardware as a given, I'm not sure.
[20:12:27] <richlowe> I think assuming it is pushing things, though.
[20:13:17] *** nikolam <nikolam!~nikolam@unaffiliated/nikolam> has quit IRC (Excess Flood)
[20:13:51] <LeftWing> You should at least support MSI.
[20:13:56] <daleg> yeah, the context is in the general sense
[20:14:16] <LeftWing> But running under some virtualised environments, for instance, we might not currently get anything but fixed interrupts.
[20:14:26] <daleg> true
[20:14:36] *** nikolam <nikolam!~nikolam@unaffiliated/nikolam> has joined #illumos
[20:14:39] <LeftWing> (Some of that is our fault, but still.)
[20:15:11] <LeftWing> I think ultimately you need to be able to work when only given a single firing that might not be for you.
[20:15:37] <LeftWing> Because even if you get an MSI-X interrupt, you might only get one.
[20:15:53] <LeftWing> At which point the structure for supporting fixed interrupts is really not much of a stretch.
[20:16:22] <LeftWing> I would say that you _can_, at this point, punt on dealing with "high level" interrupts -- i.e. fail to attach if you are given something above LOCK_LEVEL.
[20:16:43] <daleg> this was just an idle question in my mind as I try to figure out how x550 is different from the other ixgbe devices when it comes to legacy and MSI
[20:17:04] *** matejz <matejz!~matejz@element.planetq.org> has joined #illumos
[20:17:07] <richlowe> LeftWing: doesn't pretty much everyone do that anyway?
[20:17:29] <LeftWing> richlowe: Yes, but if you read some of the older materials it still talks about the two-level approach.
[20:17:31] <richlowe> I seem to think that WDD as said to do that for approximately ever.
[20:17:57] <LeftWing> I feel like WDD pushes you toward doing the two-level hard/soft pair.
[20:18:04] <LeftWing> But I might have read an old copy.
[20:18:13] <richlowe> my memory says you read a _really_ old copy, if that's the case
[20:18:22] <richlowe> or I read something other than WDD and am conflating.
[20:18:38] <LeftWing> Regardless: no longer really needed on any platform we have.
[20:18:49] *** evanl <evanl!~Adium@108.161.22.132> has left #illumos
[20:18:56] <richlowe> LeftWing: a brave statement!
[20:19:09] <richlowe> given everything else it applies to people find ways to argue with :)
[20:19:36] <LeftWing> I think that being able to legitimately disagree on this point is probably tantamount to adopting maintenance of the less interesting platforms. :P
[20:19:41] <richlowe> charitably, I'd say about 30% of usr/src/uts isn't needed on any real platform we have :)
[20:22:42] <rmustacc> daleg: You need it because you can run out of interrupts.
[20:23:01] <rmustacc> Put enough devices into the system and they can't all get MSI-X interrupts.
[20:23:04] <rmustacc> Or even MSIs.
[20:23:13] <rmustacc> So yes, you should make sure that the devices always support fixed interrupts.

[20:39:19] <richlowe> is that generally the case, or because of devices/drivers that will use multiple (and sometimes many) MSI interrupts?
[20:39:26] <richlowe> whatever it was the IRM was meant to fix, then sort of didn't.
[20:45:57] <rmustacc> It's a platform thing.
[20:46:03] <rmustacc> You can run out of interrupts regardless of IRM.
[20:46:11] <rmustacc> There's only so many interrupts available at a given IPL.
