triggered by be91fb29d950 Luke Wagner — Bug 674597 - abort if attempting to create an xpcom proxy for wrapped JS (r=bsmedberg)

me too Mozilla/5.0 (Windows NT 5.1; rv:8.0a1) Gecko/20110812 Firefox/8.0a1 ID:20110812030744

Well, it looks like we have a binary component attempting to create an xpcom proxy for wrapped JS. This is an invalid/unsafe operation.

To be clear: that's all bug 674597 does; check and abort.

Can reproduce, the offending NS_GetProxyForObject is http://hg.mozilla.org/mozilla-central/file/cec797d85529/security/manager/ssl/src/nsNSSIOLayer.cpp#l394; Echofon must be implementing a nsIDocShellTreeItem.

This fixes the assert for me. I just did a simple conversion to runnable like bug 674571. Kai: before bug 674597 and with this patch, the "rootItem do_QI is null" assert fires (this is with Echofon installed); can I remove it?

Comment on attachment 552804 [details] [diff] [review] fix Wrong.

Kai, there was a peculiar thing (we think a bug) where NS_ProxyRelease was being called in secureUI right before secureUI was used again. I just wanted to call your attention to this so you could double check.

Luke, I found another problem similar to this in the same code path: we will sometimes try to create an XPCOM proxy for an nsIPrompt that is implemented by JS. I am working on a fix that this, that, and at least one other related bug with a single runnable. I would rather use that solution than this one.

Brian, thanks a lot for your help on this. I have two patches converting two more sites where proxies are used into runnables (bug 678440 and bug 678547), one of which is an nsIPrompt, so hopefully this helps. I'm now actively investigating this bug.

Oops, I have my bugs confused; this is bug 678440 and I am investigating bug 678706. But bug 678547 does have the nsIPrompt patch.

EnsureDocShellDependentStuffKnown is called (through GetPreviousCert) on the critical path of certificate chain validation in the SSL handshake. AFAICT, adding a sync dispatch to it will cause certificate path validation--and all network I/O--to wait for the main thread's event queue to drain. I do not know how much of a performance impact that would have but I think I have an alternative solution with better performance characteristics. Will post soon.

IIUC, this wouldn't be *adding* a sync dispatch, but replacing the (slower) one inherent in proxies. Actually, this patch replaces three proxy dispatches (each doing a round-trip sync). You know the code better so I'm happy to let you do the patch though.

bsmith has some patches to kill most proxies in ssl (bsmedberg also has a patch under review to remove *all* xpcom/proxies). However, neither of these will be landing in the next day or two, so bsmith and I agreed to just back out the offending patch and dependent asserts. This is just a backout, so no r=, just approval to land on just-branched aurora.

Build identifier: Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0 I tried to install the plugin from the link in bug description but plugin can not be installed because it is incompatible with Firefox 8.0. Is there another version of plugin that is compatible with Firefox 8? Thank you!

Mihaela, I notice that Echofon 2.2.4 beta 1 compatible with Firefox 8 http://www.echofon.com/twitter/firefox/Echofon_beta.xpi
