Attached patch bug1233237.patch (deleted) — Splinter Review
presumptive blocklisting patch for the involved .dlls researching the issue, it appears that nvidia has released this type of software a great while ago already (and that's why predominantly older windows versions are affected) and may no longer maintain it. the overall correlation data also suggests, that those dlls are not used very widely, so the damage of blocklisting them might be minimal compared to the benefits...

I remember this old application filter from Nvidia, it was in nForce boards, and causing P2P clients like µT crash and internet connection issues. https://www.google.com/search?q=utorrent+nvidia+application+filter
In bug 1233934, there is a French user affected by this startup crash on Win XP, as previous versions work, I guess it could be a regression in FF too.
signatures related to this crash are currently taking #1,#2 & #4 on the top crash score board for 43.0.1 due to being a recurring startup crash: https://crash-analysis.mozilla.com/rkaiser/crash-report-tools/score/?version=43.0.1&limit=30
I think we should take this on release for 43.0.2 (contingent on review).

feedback from affected users tells that the blocklist entry does indeed solve the crashes, but firefox is unable to load any pages afterwards. not sure if this is a desired outcome - for diagnosing the issue for the purposes of support it may be easier if the browser just crashes (as the crash id will give clues about this problem). any thoughts on this - should the blocklist entry be reverted?
Status: RESOLVED → REOPENED
Resolution: FIXED → ---
Aaron, what do you think about that?
Flags: needinfo?(aklotz)
*sigh* For the short term, I think we'll have to revert the blocklist. The problem is probably that some of these DLLs are Winsock LSPs. Preventing their loading is insufficient -- we also need to prevent winsock2 from seeing the DLL as an integral part of the protocol stack. I have a few ideas for this, but in the meantime, let's revert.
Flags: needinfo?(aklotz)
philipp, what percentage of these crashes belong to Windows XP users?
Flags: needinfo?(madperson)
from the query in comment #1, 45% of the crashes were from xp users. (i'm also unassigned from the bug since anything different from a simple blocklisting patch is beyond my capabilities)

Thanks philipp! I'm sorry that your patch wasn't able to fix this 100%!
Jason, do you or your team have any idea why we might be suddenly seeing this crash spike in 43? For some reason this nvidia LSP doesn't like us.

Please go ahead asap, please land the backout asap as I will start the build soon. Next time, please request the backout in a different bug. It makes the life of everybody easier.

https://hg.mozilla.org/releases/mozilla-release/rev/362cb79ce600 Unsure if this needs backed out of anything else, but those are less pressing than release.
Added to the 43.0.3 release notes with "Fix network issue when using Nvidia's Network Access Manager (1233237)" as wording. By the way, I hope this bug doesn't prevent the updater to work...

guijoselito, could you please help me understand why was this bug reopened? I was under the impression that we took a fix for this a few days back in all the relevant branches (Beta/Aurora/Release).
Flags: needinfo?(guijoselito)
This bug is about the crash spike. A fix for this landed on comments 12, 13 and 14. On comment 17 it's said that the fix is causing connections problems. Comments 29, 30, 31 and 33 are the backouts from the patches landed earlier. So, now, there is no connections problems, but the crashes are still happening.
Flags: needinfo?(guijoselito)
I'm on one of those NVidia nForce PC. the crash mentioned are fatal for my system. if Firefox crashes, it crashes the whole system by freezing it. I have to power cycle or reset my system and firefox will show that it's unable to restore previous sessions. my home page is set to restore tabs in previous session. 43.0.2 was unable to load any page until I did the following to reset network in elevated prompt on Win 7. firefox's tech support page mentioning DNS, IPv6 and a bunch other things didn't help. Ironically, I had to use Chrome for 2 days to look for help. I thought I could use Firefox 42 32-bit while test/try things on Firefox 43.0.2 64-bit, but that didn't work netsh winsock reset catalog ipconfig /flushdns ipconfig /registerdns

Got it. Reversting the status flags in that case.
It seems this was backed out before the 43.0.3 release, but not removed from the release notes: https://www.mozilla.org/en-US/firefox/43.0.3/releasenotes/
Flags: needinfo?(sledru)
The release notes are correct. Just that we should have create a new bug. 1) we had a crash 2) we decided to blacklist the ddl 3) we released 43.0 with these dll blacklisted 4) it caused some unexpected changes in behavior (no network). Comment #17 5) we reverted the blacklist and published 43.0.3 with this change

I'm on one of those NVidia nForce PC. The crash is not fatal for my system (windows XP 32bits). On Firefox 43.0.3.5835 connection work but Firefox crash a few seconds after starting. On 43.0.2 (or 43.0.1, I'm not sure) connection not work but Firefox not crash. I'm using an other lan card (without nforce chipset) and it is the same. For info, I don't have nvlsp.dll { "nvappfilter.dll", MAKE_VERSION(2, 2, 0, 6531) } mean just the version 2.2.0 of nvappfilter.dll is concerne by the patch ? Thanks a lot
hey davidfr, this blocklisting entry meant that version 2.2.0.6531 of nvappfilter.dll and below were blocked (which has been reverted in 43.0.3 again due to causing different issues). if you can reproduce the crashes reliably on startup, it would be very helpful if you could run the mozregression tool, which could narrow down the timeframe in which firefox builds this crash first occurred (that might give developers a clearer picture and maybe an possibility to fix it as well): https://mozilla.github.io/mozregression/ in case you just want to quickly fix the issue, uninstalling nvidia's firewall was generally reported to solve the crashes: https://support.mozilla.org/en-US/kb/connectivity-crashing-firefox-43-update
Flags: needinfo?(davidfr)
Hey philipp, thanks for you message. (I have a version < 2.2.0.6531 of nvappfilter.dll) I will see for the mozregression tool I don't want to unistall Nvidia's firewall, I like the concept of hardware firewall, and honestly I'm using it for 10 years. I have use it this a lot of software including µT and other P2P software without any issus. (I have put in in advanced mod) My solution for the moment is to keep Firefox 42 : https://ftp.mozilla.org/pub/firefox/releases/42.0/win32/

so the most interesting thing in that range (from comment 47) is Bug 1152046 - Make separate thread only for PRClose I have a untested theory.. the LSP isn't threadsafe and it hooks both socket() (or perhaps connect()) and then later close() and something bad happens inside the LSP because now close is being handled on a different thread. Dragana, Honza - thoughts on that idea? Dragana, do you think we can give DavidFR a test build that just does synchronous closes (backing out that patch would be hard I know)?

Thanks DavidFR!

Target Milestone: mozilla46 → ---
If we can give out a try build with reserialized close calls and get back results, then let's do it. I think it should be fairly easy to disable it.
Flags: needinfo?(honzab.moz)
I will disable doing close on different thread. The build is coming soon.
Hi Dragana, I have try it, it works (don't crash and Internet work) :-) good job !!!! But it have other problems (I'm think it's not caused by nvidia) : - The recovery tabs don't work (it open the gool number of tab, but blank and without url), with a profil use on firefox 42. - When I'm using the proposition on the adresse bar, website don't load. But I enter a new url it work well. Whith a profil made by this nithly it is the same : - For the existing url (like https://www.mozilla.org/en-US/contribute/). I begin to enter mozilla in te adress bar, adress bar propose https://www.mozilla.org/en-US/contribute/ and if i clic on it, the website is never open ! And the url go off, the tab title is " Connecting..." with the circle. - The recovery only recovery new tabs It's just for information, I don't think it is caused by nvidia. Thanks for you work and reactivity :-)

Should we backed out this change for all users or only for with certain dlls (if it is possible)? I could leave ClosingService for UDP sockets similar as it used to be before bug 1152046?

I'm also working on a special LSP blocklist but that's not something that we'd want to uplift.
as discussed in the necko meeting today - we're concerned in general about the threadsafeness of lsp's and we're going to revert back all of the close behavior to be synchronous on the socket thread. That does bring back some intermittent error reports where close() blocked for a bizarrely long time, especially during shutdown that will need to be further battled - but this data on nvidia indicates something pretty fundamental that might not be limited to just that LSP. dragana and bagder are going to do the change work to make this synchronous again. I think its a candidate for 45 and 44 myself.
