Bug 1765132 - Make it possible to retry different IP family address when restarting a transaction, r=#necko
48 bytes, text/x-phabricator-request
Details | Review

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:99.0) Gecko/20100101 Firefox/99.0

Steps to reproduce:

Open this exact sites:

  1. https://www.avito.ru/profile
  2. https://www.banki.ru/
  3. https://volgograd.dom.ru/user/login

Actual results:

  1. (Registration required.) No page displayed at all. Convulsing TLS-handshake attempts show at statusbar. Other than that this site is working fine.
  2. Dropdown menus on top of the page do not dropdown. Comments on the news do not open up.
  3. Can't select login type (no reaction). Password window is not masked. Login button doesn't react at all.

Expected results:

Things already done: adblock disabled and then uninstalled, cookies/cache wiped, user profile wiped, entire Firefox reinstalled: no effect at all. But wait, ther's more. Two completely different pcs with the same Firefox version show exactly the same symptoms.
No other sites are affected. Not even monstrously complicated like youtube.

The Bugbug bot thinks this bug should belong to the 'Toolkit::Password Manager' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Update. This bug has nothing to do with Password Manager. I don't use it anyway.
The problem vanishes once I disable ipv6. Everything start working as it should.
Reenabling ipv6 brings the problem back.

Thanks for this! I'll move this to networking so the networking folks can take a look - they'll probably have more questions...

Hi Reporter,

Are you still able to reproduce this?
If yes, could you try to capture a http log?

Thanks.

Thanks.

Yep, still perfectly reproducible. Could it be becouse my isp doesn't have a dns6 server? I doubt it's the reason though. Ironicaly the third link is theirs account login page.

Anyway I made these logs for avito and banki. Surprisingly huge. Hope it helps.

Summary: A number of sites are partialy corrupt and unusable → IPV6 issue: a number of sites become partialy corrupt and unusable

Interesting detail. Brave browser on an android smarphone shows exactly the same issue.
But Firefox on the Astra Linux (Debian based) machine works fine (I doublechecked that ipv6 is enabled). This all is very confusing.

Thanks for the log. I can confirm this is related to IPV6.
From the log, I can see Firefox tried to connect to this address 2a03:90c0:9999::9999.

2022-05-10 04:28:54.021000 UTC - [Parent 72: Socket Thread]: D/nsSocketTransport nsSocketTransportService::AttachSocket [handler=1a9fba13c00]

We successfully connected to the server.

However, when we tried to send HTTP request, the socket was reset by server.

Then, we tried to connect again with the same IPV6 address.

The new socket was reset by server again.

In the end, we reached the retry limit.

2022-05-10 04:28:59.467000 UTC - [Parent 72: Socket Thread]: V/nsHttp reached max request attempts, failing transaction @1a9fdc22c00

Maybe this is a server side issue, since the socket is rest by server and this also happened on the other browser.
However, there might be one thing we can do: when restarting a transaction, don't use the same IP address to connect.

So... correct me if I'm wrong... There's an attempt to connect to 2a03:90c0:9999::9999 that is a DNS6 server and it fails.
As I said my ISP doesn't have it's own DNS6 server so this one that refuses connection is located elsewhere. Doesn't surprise me that it refuses.
But why not just fallback to DNS4 server after a failed attempt with DNS6?

We do have a fallback mechanism to IPv4, but that mechanism only works when the socket is in CONNECTING state.
In this case, the socket is already in TRANSFERING state.

I'll try to fix this.

This seems to fix a serious problem for the users affected but I don't know if many users are affected and if this could be a safe uplift to beta, kershaw what do you think about it?

I don't think many users are affected by this, since this issue is only happened with a specific networking environment.
I am also not sure if my patch really works, since I can't write a test for this case.
So, let me ask the reporter to verify first and we can decide whether to uplift.

Hi David,
Could you download the latest Firefox nightly and see if this issue is fixed?
Thanks.

Thanks.
Hello. I certainly can. But the problem vanished on its own ~ a month ago. I'm using IPV6 flawlessly ever since.
If you still need something tested I'm willing to help, just provide me a step by step guide on the procedure.

Thanks. I think it's no need to do further tests.
