https-dns-proxy: high CPU/memory usage, crashes

Mrnofish commented 4 years ago

Maintainer: @stangri Environment: mips 24Kc, TP-Link WR1043ND v1.8, OpenWRT 18.06.7

Description:

To reproduce: start a browser that will restore a saved session, performing a number of look-ups.

CPU usage will skyrocket. On occasion, memory use will also surge triggering an OoM crash that results in a zombie slowing down the router to a crawl (load reads 2 to 3)

Initially, I thought it was just the router having too little memory, however, after switching to stubby, which appears to have a similar memory footprint, everything has been working flawlessly.

@aarond10.

Note - there was a recent patch in upstream to fix a memory leak (https://github.com/aarond10/https_dns_proxy/commit/40647ce94c62a47e9d53efae8018fb3142e277b9) ... perhaps this might be related

stangri commented 4 years ago

Thanks, PRs for the new version: https://github.com/openwrt/packages/pull/11819, https://github.com/openwrt/packages/pull/11820, https://github.com/openwrt/packages/pull/11821. Once they are merged, the new package should be available in repos withing a few days, please test if it fixes the memory leak.

dmascord commented 4 years ago

This seems potentially related to the ipv4 vs ipv6 configuration.

https://openwrt.org/docs/guide-user/services/dns/doh_dnsmasq_https-dns-proxy suggests to use ipv4_resolvers setting, but the init scripts use the opposite configuration use_ipv6_resolvers_only.

I have modified my configuration to use use_ipv6_resolvers_only 0, rather than ipv4_resolvers 1, and will monitor to see how it behaves.

EDIT - OK, no difference at all, this is just a red herring.

Running apt update on a client machine, with a number of repo's activated often triggers this issue, both dnsmasq and https-dns-proxy consume 50% of the CPU each, and it essentially hangs,

8750 1 nobody R 5052 4% 48% /usr/sbin/https-dns-proxy -a 127.0.0.1 -p 5053 -b 1.1.1.1,1.0.0.1 -r https://cloudflare-dns.com/dns-query -u nobody -g nogroup -v -4 8742 1 dnsmasq R 9564 8% 47% /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf.cfg01411c -k -x /var/run/dnsmasq/dnsmasq.cfg01411c.pid

I can reproduce pretty easily with https://github.com/jedisct1/dnsblast, and can confirm that stubby does not exhibit the same behaviour.

I was running strace on the router, and captured the strace output, and I can see some errors:

connect(8, {sa_family=AF_INET, sin_port=htons(443), sin_addr=inet_addr("104.16.248.249")}, 16) = -1 EINPROGRESS (Operation in progress) poll([{fd=8, events=POLLOUT}], 1, 0) = 0 (Timeout)

stangri commented 4 years ago

Did you modify the init script in any way?

ghost commented 4 years ago

Same issue here, https://github.com/aarond10/https_dns_proxy/commit/40647ce94c62a47e9d53efae8018fb3142e277b9 does not fix it for me.

I noticed memory usages usually increases when my ISP router reboots:

network -> openwrt (https-dns-proxy) -> ISP router -> internet

aarond10 commented 4 years ago

Thanks @willymilkytron, that's a useful data point. There is at least one bad thing going on with libcurl but I haven't figured out exactly what yet. Worked fine for months, so I suspect it's triggered by either IP changes (DNS round robin?) or some http/2 server behavior.

stangri commented 4 years ago

@aarond10 do you think it may be beneficial to test with -x on the systems with abnormal CPU/memory usage?

caliban511 commented 4 years ago

同样遇到 https_dns_proxy 占用CPU过高的问题。我的CPU是J4205，但这个进程一开，CPU平均占用就会上升到50%左右。这个问题不知道什么时候能解决一下？

aarond10 commented 4 years ago

I'll need more details. Ideally some gprof output with a debug build or at the least the output of the daemon running with -vvvv so I can try to infer what it's doing.

大佬你好，请问你用过passwall.ipk这个软件吗？我试过用最新版19.07.4的原版openwrt，安装passwall，会自动安装 https-dns-proxy ，然后只要它被装上就会立即引发这个问题，启用passwall就出现，百分之百重现，要不大佬你试试？这里是passwall的下载地址：https://t.me/passwallIPKnb

caliban511 commented 4 years ago

我自己尝试编译lienol大佬的代码生成固件后，发现并没有这个问题。所以这应该是软件和原生固件之间的兼容性问题了。问题终结。

aarond10 commented 4 years ago

It's an odd compatibility issue. 25% I assume is one of four cores so it might have been spinning trying to do something. I'll close for now, but feel free to reopen it if you think it's still a problem.

aarond10 commented 4 years ago

On second thought, I'll leave this open for a little longer given the multiple reports. I've not been able to reproduce myself since the commit about a month ago now that forces curl to abort active HTTP2 sessions if the IP address of the resolver changes. I'm wondering if that was part of the problem here.

Mrnofish commented 4 years ago

Isn't there a rule that all submissions should be in English?

If there is, it should be enforced. If not, there should be one.

caliban511 commented 4 years ago

Sorry, I don’t understand English. This is using Google Translate to reply. There are some unsatisfactory words. Please forgive me. This problem of abnormal CPU usage occurred when I installed a software called passwall with the original openwrt firmware. The source code of this software is here: https://github.com/xiaorouji/openwrt-package/tree/master/lienol/luci-app-passwall When I try to use the source code modified by the same person, compile it into openwrt firmware and use this software, the above problem does not appear. The revised firmware source code is here: https://github.com/Lienol/openwrt Because I don't understand these codes and only use them, I can't make any constructive comments. It can only be simply considered that this may be a compatibility issue between the original firmware and the software. I can't solve it, I can only avoid it. If this troubles you, I'm really sorry. Thank you for your continued work and dedication.

obhasqr commented 4 years ago

I found that setting up an unreachable doh server will cause high CPU usage. I can‘t access Google doh server. If I set up Google doh server in https-dns-proxy, it will cause my router's CPU to be occupied by more than 50%.

Add Google doh: Delete Google doh:

stangri commented 4 years ago

@aarond10 does the comment above shed any light on possible fix for high CPU utilization?

stangri commented 3 years ago

@caliban511 @obhasqr -- can you please test the 2020-08-21-1 version and see if you can still reproduce the problem.

obhasqr commented 3 years ago

Hi @stangri , 2020-08-21-1 can still reproduce this issue.

aarond10 commented 3 years ago

Sorry for the slowness. I just removed the libcurl workaround code. It shouldn't be needed and looks like it was actually the cause of this.

2021-01-17-1 works fine for me.

Safe to close this then? Can anyone still reproduce the high cpu usage with the 2021 builds?

Both Extended test and DNS Spoofability Test don't let https-dns-proxy crash or stay at 100% CPU time.

To be fair, before OOM in https-dns-proxy the attached dmesg shows OOM messages for haproxy and node/netdata. Am I reading it wrong or it doesn't look like it's a https-dns-proxy issue?

Yes, but https-dns-proxy used the most memory. If I don't enable https-dns-proxy, system won't kill other applications.

You may want to share the package settings, to help reproduce the issue (and just to double-check the version, output of opkg list-installed https-dns-proxy).

ghost commented 3 years ago

The memory leak is still happening on my router running 19.07.5 with

https-dns-proxy - 2021-01-17-3
luci-app-https-dns-proxy - 2021-01-17-2

I'm trying to reproduce the issue on a different device since i can't install/use gdb and valgrind on the production router.

nirui commented 3 years ago

Yep. I'm still encountering the unrecoverable 100% CPU usage problem, randomly. In fact, it happened so random, I can't reproduce it this time.

A weird thing is, the https-dns-proxy does go to 100% CPU during "normal" situations on my router too, then it just back down after about a half minute. While during the "not-normal" situation, it does not go back down. My knowledge tells me, HTTPS requests should not take that amount of CPU time since it's mainly an I/O work of the network not CPU, unless something goes really wrong.

I'm currently running it in debug, hope something show up in the log.

So far, however, in addition to the CPU usage problem, I've also observed that the process https-dns-proxy has established a huge amount of connections to the HTTPS DNS server:

stangri commented 3 years ago

Have you tried using it with Cloudflare/Google servers and see if you can reproduce the error? Maybe it's something in the https-dns-proxy config or your resolver.

nirui commented 3 years ago

Well, I have to use some "weird" configuration (a socks5h proxy on 127.0.0.1:1080) for Google and Cloudflare server as they are not directly accessible in my network, so I expect their result to be even weirder.

Anyway, here is the result of netstat -utpWn | grep "https-dns-" > /tmp/netstat.txt (without filtering): netstat.txt. Notice there are many connections to 127.0.0.1:1080 too.

And here's the configuration of https-dns-proxy generated via luci-app-https-dns-proxy:

# cat /etc/config/https-dns-proxy 

config main 'config'
    option update_dnsmasq_config '*'
    list force_dns_port '53'

I've already tested the socks5 proxy. It works fine and no looping DNS query issues there.

Could you try removing the IPv6 bootstrap_dns, or set them to a consistent and contactable server? The DNS error you posted suggests that the bootstrap DNS resolution is failing (dns_poller.cc, line 66). That shouldn't happen intermittently unless you have a very very flaky network. More likely some of the DNS server entries aren't working.

You can use dig www.google.com @119.29.29.29 or similar to test. FWIW, you only need those DNS servers to work to look up the main resolver address so there isn't a real advantage to them all being different either.

During the same time, the socks5h proxy (127.0.0.1:1080) was also generating multiple getpeername: Socket not connected errors, indicating it cannot connect to the remote. I guess there is a bug in https-dns-proxy that only randomly triggers during connection failures.

That's all the information I've gotten so far. Hope it helps :)

EDIT: Better format.

This occurs for me when I add a firewall rules to block port 53 instead of hijacking port 53. Hopefully, this helps reproduce for people. I disabled the port 53 blocks, and the issue went away. Here's the firewall rules used.

Why the rules? I noticed port 53 was still opening when running namebench. Namebench won't run while hijacking. The rules below are disabled.

config rule
    option target 'REJECT'
    option dest 'wan'
    option dest_port '53'
    option name 'Block port 53 leaks'
    option enabled '0'

config rule
    option dest_port '53'
    option src 'lan'
    option name 'Block port 53 leaks'
    option dest 'wan'
    option target 'REJECT'
    option enabled '0'

Here is a screen grab. I disabled the rules then re-enabled. I then navigated to one web page. As you can see, once I do dns queries for the web page. The CPU get stuck in a loop with firewall rules in place. Whoever suggested it was DNS lookup error related seems to be on the right track to me. Loop seems to be caused by failed connections on port 53 at a minimum.
