 40 2018-10-16T02:57:08  <kallewoof> How does bitcoin core track bip9 activation states? I have odd cases where a copied chain state will result in all bip9 soft forks turning up as "failed" rather than "activated". If I disable the timeout, they show up as 'started', but with 'possible: false'.

122 2018-10-16T05:43:00  <wumpus> hehe
123 2018-10-16T05:43:25  <wumpus> well I remember because windows .ini format has no way to insert #'s, that's also why I know they have no quoting...
124 2018-10-16T05:44:07  <wumpus> all this is kind of terrible edge-case stuff
125 2018-10-16T05:45:18  <meshcollider> I agree
126 2018-10-16T05:46:17  <meshcollider> we should just disallow same-line comments and only exclude lines from the conf if they *start* with a #
127 2018-10-16T05:47:27  <wumpus> yes, I think that's a fair option, I remember seeing that in other software (but don't remember which one, right now); though,also a breaking change
128 2018-10-16T05:47:54  <wumpus> people might already be using # to comment their .ini files lines... so would create the *opposite* issue :(
129 2018-10-16T05:48:28  <meshcollider> yeah I think its too hard to change now
130 2018-10-16T05:48:29  <wumpus> anyhow I think 14494 is good, just don't have "illegal hash character" in the error message that's terrible :-)
131 2018-10-16T05:48:45  <meshcollider> haha ok what should I change it to
132 2018-10-16T05:49:22  <wumpus> well what I said in the PR, it's at most ambigious, it's rejected because it's probably a mistake
133 2018-10-16T05:49:35  <meshcollider> " do not use hash characters in rpcpassword" ?
134 2018-10-16T05:50:14  <wumpus> if it's an actual comment it is actually okay, in principle
135 2018-10-16T05:50:35  <wumpus> well a friendlier message, not something about 'do not use' but just explain to the user why this is a problem
136 2018-10-16T05:50:38  <meshcollider> ok
137 2018-10-16T05:50:54  <wumpus> illegal hash characer sounds like the cops will show up any time :)
138 2018-10-16T05:51:16  <kallewoof> wumpus: I think iptables will happily try to parse # chars unless they are the first on the line

242 2018-10-16T09:28:44  <luke-jr> the downgrading warning in 0.17 relnotes is confusing; why is it talking about 0.15?
243 2018-10-16T09:29:15  <meshcollider> luke-jr: because that's the version at which it changed isn't it
244 2018-10-16T09:29:57  <meshcollider> but yeah its not worded well
245 2018-10-16T09:30:04  <luke-jr> dunno, 0.16 didn't mention it
246 2018-10-16T09:30:13  <luke-jr> I thought we had a change in 0.17 too?
247 2018-10-16T09:30:14  <wumpus> I *guess* it's when you want to downgrade from 0.17 to 0.15?
248 2018-10-16T09:30:30  <meshcollider> "Wallets created in 0.16 and later are not compatible with versions prior to 0.16 and will not work if you try to use newly created wallets in older versions. Existing wallets that were created with older versions are not affected by this."
249 2018-10-16T09:30:53  <wumpus> it's a bit late to discuss 0.17 release notes, now
250 2018-10-16T09:31:10  <meshcollider> it looks like its just been copy+pasted from 0.15, oh well
251 2018-10-16T09:31:45  <luke-jr> wumpus: that's not what it says though :/
252 2018-10-16T09:31:46  <luke-jr> yes, just noticed
253 2018-10-16T09:31:51  <wumpus> it probably has
254 2018-10-16T09:32:13  <wumpus> the upgrading/downgrading part tends to be copy-pasted between releases because it tends to stay relevant
255 2018-10-16T09:32:46  <wumpus> at some point it can be removed because no one is going to downgrade to 3 major versions back, but still
256 2018-10-16T09:33:18  <wumpus> would be good to have close scrutiny of the release notes before a release

292 2018-10-16T11:24:26  <promag> wumpus: does my response clarifies your concern https://github.com/bitcoin/bitcoin/pull/14291/files#r225491304 ?
293 2018-10-16T11:26:00  <wumpus> promag: i'm personally scared of that behavior, but if others think it's ok, i'll just go along...
294 2018-10-16T11:26:44  <wumpus> promag: you're right it only scans the files at recursion depth=0 for the btree signature, though it still *nests* into all the directories nevertheless
295 2018-10-16T11:26:51  <promag> wumpus: do you think it should do that only if walletdir != datadir?
296 2018-10-16T11:28:00  <wumpus> that would, to me, seem like the most straightforward way to prevent this; then give the user a clear explanation *why* it won't work and what they can do to make it work
297 2018-10-16T11:29:15  <wumpus> one specific concern: opening and closing the .lock file will nix the datadir lock, at least on some OSes
298 2018-10-16T11:30:17  <promag> hmm, skip that filename then?
299 2018-10-16T11:30:21  <promag> ryanofsky: ^
300 2018-10-16T11:30:31  <wumpus> that seems *extremely* fragile
301 2018-10-16T11:31:54  <wumpus> maybe this brings a valid problem to light: there's just too many ways to organize the data directory with regard to wallets, all need to be handled, and tested
302 2018-10-16T11:32:06  <wumpus> in any case, I'd prefer if the RPC simply failed in that case
303 2018-10-16T11:33:07  <promag> but do you agree on the concept?
304 2018-10-16T11:37:59  <wumpus> in the case where there is a separate wallet directory, certainly!

547 2018-10-16T23:32:36  <echeveria> from the description I doubt it uses it as a data source.
548 2018-10-16T23:33:03  <echeveria> this is the company that lied in their original software release and claimed to be decentralized, while using blockchain.info in their closed source release.
549 2018-10-16T23:33:12  <gmaxwell> I know previously it used bc.i as its data source. I don't see how it would use your local node as a data source.

551 2018-10-16T23:33:59  <gmaxwell> "We build the software that Bitcoin deserves"  ... just so.
552 2018-10-16T23:38:45  <echeveria> all of their "privacy" tools are snake oil, to boot. it's unfortunate that they're impacting bitcoin node users as well as people fooled into using their incompetent software.
553 2018-10-16T23:39:04  <achow101> echeveria: removing rpcuser and rpcpassword wouldn't change that though
554 2018-10-16T23:39:12  <achow101> you can still set rpcauth
555 2018-10-16T23:39:27  <achow101> (albeit harder to do)
556 2018-10-16T23:39:50  <echeveria> achow101: it ends up being an automatically generated token, doesn't it?
557 2018-10-16T23:40:09  <gmaxwell> echeveria: no thats cookie auth.
558 2018-10-16T23:40:11  <achow101> echeveria: no, that's only the cookie auth stuff. that token goes into the .cookie file
559 2018-10-16T23:40:26  <achow101> rpcauth is like rpcuser and rpcpassword except as one config option and the password is hashed
560 2018-10-16T23:40:38  <echeveria> oh, I thought they were the same thing.
561 2018-10-16T23:41:04  <echeveria> guess that doesn't implicitly solve any issue like I thought.
562 2018-10-16T23:41:36  <achow101> i mean it's harder for people to figure out how to hash their password to use rpcauth
563 2018-10-16T23:41:50  <gmaxwell> cookie auth is a replacement for things that read passwords out of the conf file, rpcauth is the replacement for things that have a persistant key left in another app.
564 2018-10-16T23:42:46  <echeveria> yep, understood, I just bundled them together in my head. it sort of surprised my awfully to realise that so many RPC ports were open in public IPv4 scans. I'm not sure there's a resolution to that, it's already something that's non-trivial to do.
565 2018-10-16T23:43:15  <gmaxwell> I hope that many of them are honeypots, etc.
566 2018-10-16T23:43:15  <echeveria> unless the RPC bind option is changed to IM_AN_IDIOT=0.0.0. or something, which I can understand why nobody would want to do that.
567 2018-10-16T23:43:43  <echeveria> hopefully.
568 2018-10-16T23:44:14  <meshcollider> sipa: how about checking the flatsigningprovider only added a single pubkey for each descriptor, and import it if it did
569 2018-10-16T23:44:14  <gmaxwell> just change the string to a new random 256 bit hex value in each release. :P
570 2018-10-16T23:44:18  <meshcollider> Would that work?
571 2018-10-16T23:45:21  <echeveria> gmaxwell: see I'd say remove the ability to bind anything but localhost, but I know that would mean people would refuse to upgrade for compatibility reasons.
572 2018-10-16T23:45:36  <sipa> meshcollider: i have a bit of another strategy in mind
573 2018-10-16T23:45:36  <achow101> or remove rpcbind and make people figure out iptables/firewall crap to get it accessible from the outside world
574 2018-10-16T23:45:56  <sipa> meshcollider: let's focus on making importmulti work first for all supported things, and ignore descriptors
575 2018-10-16T23:46:09  <sipa> meshcollider: i think the code can be massively simplified (but let's do that after merging your PR)
576 2018-10-16T23:46:13  <gmaxwell> echeveria: it's not unreasonable to bind to a private lan, for example. just security wise fragile.
577 2018-10-16T23:46:16  <meshcollider> sipa: Alright, sounds good
578 2018-10-16T23:46:25  <sipa> and after simplification, it can share a lot of logic with the descriptor approach
579 2018-10-16T23:46:45  <gmaxwell> echeveria: maybe {stop} should work without authentication. :P
580 2018-10-16T23:47:02  <meshcollider> sipa: does this include change to the wallet or just the RPC code
581 2018-10-16T23:47:14  <sipa> meshcollider: just the scope of your current PRs
582 2018-10-16T23:47:16  <gmaxwell> echeveria: oh there you go, auto stop after 1000 invalid auth attempts. :P
583 2018-10-16T23:47:29  <echeveria> yuck.
584 2018-10-16T23:47:39  <sipa> echeveria: wumpus had some unix socket binding RPC stuff earlier, not sure what the state is
585 2018-10-16T23:48:03  <sipa> perhaps that can be made default the only open thing, and you need a separate tool to proxy it to TCP/IP
586 2018-10-16T23:48:08  <sipa> ... at some point
587 2018-10-16T23:48:12  <gmaxwell> sipa: it was held up because the client side support needed upstream improvements in libevent. :(
588 2018-10-16T23:48:17  <sipa> gmaxwell: right
589 2018-10-16T23:48:29  <echeveria> sipa: I think that results in people using obsolete versions sadly.
590 2018-10-16T23:48:43  <sipa> echeveria: quite possibly
591 2018-10-16T23:48:58  <echeveria> that's what happened with BitPay's Insight. they stopped maintaining it so everybody who built around it is still running 0.12, as far as I can tell not behind guard nodes.
592 2018-10-16T23:48:59  <gmaxwell> I do think that making it harder to make rpc remotely accessible might be a reasonable move, esp post domain socket support. (not that they're really related)
593 2018-10-16T23:49:03  <jarthur> sipa gmaxwell do you remember why we needed to re-use a socket object in libevent? Is it because we wanted the unix socket file managed by Core instead of libevent?

596 2018-10-16T23:49:13  *** bitcoin-git has left #bitcoin-core-dev
597 2018-10-16T23:49:16  <sipa> jarthur: no clue about the details
598 2018-10-16T23:49:35  <gmaxwell> echeveria: disabling it would do that, but requiring an insecure_nonlocal_binding=1
599 2018-10-16T23:49:46  <echeveria> yep.
600 2018-10-16T23:50:08  <gmaxwell> jarthur: should be in wumpus' issue in the libevent repo.
601 2018-10-16T23:50:27  <jarthur> sipa: alright. I think that's what wumpus' upstream PR was all about. I think we can do it in libevent today if we have libevent opening the socket in the first place.
602 2018-10-16T23:51:37  <jarthur> Why is this remote RPC stuff coming up? IMO, it's already hard to expose an RPC port on anything but the loopback.
603 2018-10-16T23:51:59  <echeveria> jarthur: I noticed that there's a large number of RPC sockets open.
604 2018-10-16T23:52:38  *** Murch has quit IRC
605 2018-10-16T23:52:48  <jarthur> echeveria: ah, when using Samurai? Or just listening sockets on a clean Core run?
606 2018-10-16T23:52:52  <gmaxwell> jarthur: wumpus' major motiviation behind working on domain sockets was getting bitcoind to run in a very restrictive sandbox.
607 2018-10-16T23:53:30  <gmaxwell> samurai is just one of many potential causes for the large number of rpc exposes hosts.
608 2018-10-16T23:54:02  <echeveria> jarthur: just in general, many IPv4 that have 8333 open also have 8332 open. there's various tools like shodan that present this information in an easy to consume way. samourai was just one theory of mine as to why people might be doing it, as they do suggest exposing your RPC port in some way, for a very stupid reason.
609 2018-10-16T23:54:04  <gmaxwell> (and a kind of absurd one, since it looks like they have the user open up the RPC to remote hosts just to sendrawtransaction)
610 2018-10-16T23:54:55  <achow101> even with rpcbind=0.0.0.0, you still need to be whitelisted in rpcallowip to connect though
611 2018-10-16T23:55:12  <achow101> unless people also did rpcallowip=0.0.0.0
612 2018-10-16T23:56:08  <jarthur> echeveria: alright. There's also electrumx, electrum-server, electrum-personal-server, electrs, getwork proxy, stratum mining proxies, stratum mining pools. A whole lot of RPC uses out there.
613 2018-10-16T23:56:29  <gmaxwell> none of those things should be exposing the bitcoind rpc to the wide internet.
614 2018-10-16T23:56:31  <echeveria> jarthur: none of what you've described need a world listening RPC port.
615 2018-10-16T23:56:54  <jarthur> Yea, not justifying the open port, just why people end up opening those ports in the first place.
616 2018-10-16T23:57:39  <gmaxwell> achow101: perhaps we should require  "massively_increased_security_vulnerablity_exposure=1" for any rpcallowip statement wider than /8. :P
617 2018-10-16T23:57:41  *** Murch has joined #bitcoin-core-dev
618 2018-10-16T23:57:56  <jarthur> I sometimes load up an EC2 Core server, open up RPC to the net and use Amazon Security group to only let myself have access. I got no shame in it :)
619 2018-10-16T23:58:02  <echeveria> jarthur: huh? it needs extra effort to make it bind to 0.0.0.0, which you don't need for nay of the services you talk about.
620 2018-10-16T23:58:23  <echeveria> jarthur: you're a bad sysadmin. you have SSH, forward the port locally.
621 2018-10-16T23:59:19  <gmaxwell> jarthur: the fact that its possible to 0/0 safely (although fragile) is why its possible at all.
622 2018-10-16T23:59:41  <jarthur> echeveria: yea, that's certainly better. Have done that too when less lazy.
