CSP 1.1 updates

<bhill2> http://lists.w3.org/Archives/Public/public-webappsec/2014Jan/0001.html

mkwst: 1. removed most of script interface, needs to be reworked
... suggested push out to 1.2 (policy violation event still exists)
... 2. meta element changes converting todos
... 3: Workers no longer inherit policy automatically, rather when generated from origins w/ unique urls.
... 4: new child-src directive, default context source list, used for frame/worker/popup-src directives
... and child-src inherits from default-src
... nothing governs window.open

<freddyb> in general, if you're not talking: please mute. the feedback is indeed annoying

<terri> I'm having trouble hearing much of anything because of it.

<freddyb> on a sidenote, when it comes to directives: was it discussed in this WG whether it makes sense to put html imports into script-src?

<bhill2> freddy: yes, that was the conclusion we came to

dveditz: potential issues around workers [noise]

<freddyb> bhill2: thanks. I'll read up first then

dveditz: no need for child-src && worker-src, or just have separate frame/worker-src


???: complexity is a leading blocker for adoption

<dveditz> who is speaking? apf?

<bhill2> was that terri oda speaking?

<terri> yes, I'm the former academic on the call

<mkwst> bah. dialing back in.

bhill2: Ian's ideas around CSSOM appear to have no objections and decent support
... frame-ancestors in 1.1 (not frame-options)

github ftw

Back compat in CSP

<bhill2> http://lists.w3.org/Archives/Public/public-webappsec/2014Jan/0002.html

bhill2: requiring eval for cssom might break things

mkwst: if we feel it's an issue, we need to base decisions on data
... adding eval to style-src

bhill2: does this impact chrome extensions and the like?

mkwst: no

Sub-Resource Integrity Strawman and Use-Cases

<bhill2> http://w3c.github.io/webappsec/specs/subresourceintegrity/

<dveditz> FIrefox OS privileged apps have a default CSP of "default-src *; script-src 'self'; object-src 'none'; style-src 'self' 'unsafe-inline'"

<dveditz> but we could easily add "unsafe-eval' to the style-src if we make this change

<freddyb> certified apps (internal things like dialer, sms, ..) don't have 'unsafe-inline' for styles yet

<freddyb> privileged do

1) pros: ensure unauth'd code alerts, cons: might slow things down, might break things

terri: intro needs to be clarified to distinguish from what CSP does

2) "cdn integrity" pros: no brainer, cons:

3) "integrity for downloads" cons: result of navigation before direct download might cause issues in a new context

bhill2: is this meaningful? copy/pasting urls is a workaround as well

4) "Ensure UI elements aren't manipulated before being displayed"

interaction with about:// could be controlled

mkwst: chrome new tab page is another example

freddyb: some of these pages are privileged as well

mkwst: 1, 2, 4, 5 can probably be consolidated

<bhill2> next call will probably be Friday, Jan 31
