Comment 9

[Nicolas B. Pierron [:nbp]]

Looking briefly at the most recent android failures the following test case seems to show up frequently (among the low likelyhood of intermittent failures): dom/xhr/tests/test_xhr_progressevents.html

I do not know if there is any mean to have rr / pernosco support on android x86_64, but this might be one way to investigate.

Comment 32

[Jon Coppeard (:jonco)]

Setting security sensitive because this could result in use after free if we sweep something that should have been marked.

Comment 33

[Andrew McCreight [:mccr8]]

I'll mark this high, then, though I'm not sure if it is actionable, so it may end up stalled.

Attachment: Bug 1871303 - Ensure there is no more marking at the start of sweeping r?sfink

There are two issues here. The first is that there unexpected marking work at
the start of sweeping after entering from the mark phase without yielding. We
previously called assertNoMarkingWork() after markUntilBudgetExhausted() in the
marking phase so something since then must have added it.

As far as I can tell this must be the conditional call to
collectNurseryFromMajorGC(), where a post barrier for a pointer cleared during
finalization (e.g. for Maps in mapObject::sweepAfterMinorGC) ends up marking
something. I'm not sure such barriers are necessary, but for now the safest
thing to do is to move this nursery collection to the start of the slice so
that it happens before we drain the mark stack.

The second issue is that we check the budget and conditionally yield if we
enter from the marking state. The comment above this code states that this is
not safe since we have not yet started sweeping a sweep group. This check was
added in bug 1865383 but was not the main part of the fix. I think we should
remove this.

I wasn't able to come up with a test case to reproduce this.

Bug 1871303 - Ensure there is no more marking at the start of sweeping r?sfink

Security Approval Request

• How easily could an exploit be constructed based on the patch?: Very difficult.
• Do comments in the patch, the check-in comment, or tests included in the patch paint a bulls-eye on the security problem?: No
• Which branches (beta, release, and/or ESR) are affected by this flaw, and do the release status flags reflect this affected/unaffected state correctly?: All (back to FF86)
• If not all supported branches, which bug introduced the flaw?: 1681533, 1865383
• Do you have backports for the affected branches?: No
• If not, how different, hard to create, and risky will they be?: They should be trivial.
• How likely is this patch to cause regressions; how much testing does it need?: This is a fairly simple patch that removes a possible yield point from GC and moves nursery collection earlier in the process. It's unlikely to cause regressions.
• Is the patch ready to land after security approval is given?: Yes
• Is Android affected?: Yes

The patch landed in nightly and beta is affected.
:jonco, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
• If no, please set status-firefox129 to wontfix.

A patch has been attached on this bug, which was already closed. Filing a separate bug will ensure better tracking. If this was not by mistake and further action is needed, please alert the appropriate party. (Or: if the patch doesn't change behavior -- e.g. landing a test case, or fixing a typo -- then feel free to disregard this message)
