1544765 - Crash in [@ mozilla::ipc::FatalError | mozilla::ipc::IProtocol::HandleFatalError | mozilla::dom::PContentChild::OnMessageReceived] | Error deserializing 'BrowsingContext'

Status: RESOLVED WORKSFORME

(Core :: DOM: Content Processes, defect, P3)

Description

[Marcia Knous [:marcia]]

This bug is for crash report bp-ff31c60c-550d-4f90-9b5d-fea440190415.

Small cross platform spike on nightly 68 which started in 20190415213626: https://bit.ly/2De0zko

All crashes have Moz Crash reason: IPDL error: "Error deserializing 'RefPtr'". abort()ing as a result.

Possible regression range based on Build ID: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=adc32d869e58d0c052094f718bc9e4cff8390be4&tochange=b8f49a14c458f56a6a08e4c177671108e386be3a

The only IPC related bug in that range is Bug 1494469, unless the crash is being caused by something else.

[Marcia Knous [:marcia]]

ni on Jed Davis to see if he can clarify what might have caused this small spike.

Comment 2

[Calixte Denizet (:calixte)]

It could be related to changes about BrowsingContext too.
:nika, could you have look please ?

Comment 3

[Calixte Denizet (:calixte)]

Forgot to set the needinfo.

Comment 4

[Nika Layzell [:nika] (ni? for response)]

I'm inclined to wait for :jld's work on bug 1544825, as it can greatly improve diagnostics and help figure out what might be going on here.

Until bug 1544421, we didn't actually check validity of BrowsingContext within the deserializer correctly, so I doubt it's caused by that in particular.

(In reply to :Nika Layzell (ni? for response) from comment #4)

I'm inclined to wait for :jld's work on bug 1544825, as it can greatly improve diagnostics and help figure out what might be going on here.

The patch I have will tell us what type is causing the problem, but if it's something complex like nsIInputStream there's still a lot of information about what went wrong that won't be captured.

Comment 6

[Julien Cristau [:jcristau] (back April 22)]

In the last week it looks like we've had:

• IPDL error: "Error deserializing 'BrowsingContext'". abort()ing as a result. e.g. bp-4ff7f756-4a2d-4a59-92af-d067f0190427
• incorrect sentinel when reading Error deserializing 'uint64_t' e.g. bp-4425d869-12ef-43cb-90b0-ee1e60190429
• incorrect sentinel when reading Error deserializing 'name' (nsCString) member of 'PluginTag' e.g. bp-4a289046-c79f-414b-bdeb-93fed0190425

Comment 8

[Jed Davis [:jld] ⟨⏰|UTC-7⟩ ⟦he/him⟧]

Breaking down the recent failures under this bug's crash signatures by Ipc fatal error msg, there are a lot of Error deserializing 'PBrowserParent' but they're only on ESR. Limiting to Nightly, it's only Error deserializing 'BrowsingContext' (the other ones mentioned in comment #6 have different signatures), so I'm handing this over to DOM.

WFM. No crash reports since December. This crash signature is extremely generic and not useful.
