a small number of windows xp users (sp2 & sp3 as well) are reporting that they cannot launch firefox after the update to version 36 as it only produces an error message on startup: firefox.exe - entry point not found The Procedure entry point GetLogicalProcessorInformation could not be located in the dynamic link library Kernel32.dll in conversation on irc it was asked that the users produce a crash report from their affected system - this is one from a user who followed up on it: https://crash-stats.mozilla.com/report/index/6384bb2a-2428-4332-9e33-6f9ee2150227 for reference, those are the threads in sumo about this issue: http://mzl.la/1DxMxT8
[Tracking Requested - why for this release]: [Tracking Requested - why for this release]: this might be a regression from Bug 1023941 with major impact for affected users since they cannot start firefox anymore.

So, for that particular person on that particular crash: - The system version is claimed to be SP3 - Most libraries are version 5.1.2600.2180, which is SP2. IOW, their system is a mixbag of SP2 and SP3. The code added in bug 1023941 applies the patch for GetLogicalProcessorInformation if the detected system is SP2, not SP3... So I guess we should check the kernel32.dll version instead...
Ironically, the VerifyVersionInfo function that is being used for the version check, comes from kernel32.dll... but it must be asking the actual kernel, not relying on its own version.
Note that this means we can tell at least some of these people that they should re-apply the service pack.
It would be good to get a crash report from one of the persons saying they are using SP2, because this surely should be working on SP2. Maybe Firefox sees those as SP3 too.
Important issue, tracking. FYI, there is also bug 1136775 about Windows XP SP2.

It's *not* the same issue.

Yes, sorry, that was a typo (initially, I though it was the same bug but noticed it was different but didn't remove the duplicate operation). Sorry.
Apparently bug 1023941 fails to patch the CRT somehow.

Robert, could you help on this?

only could obtain one crash report from another affected user on xp sp3 which shows the same picture: https://crash-stats.mozilla.com/report/index/5032294c-3b1e-4a50-a805-afb552150228

The easy way forward here would be to apply the crt patch for all XP versions. A more involved way forward is to check the kernel32.dll version instead of the XP version. Either way, if for the people claiming to be on SP2, Firefox sees SP2, there is another problem, but we'd need a crash report to know for sure.

I don't think we'll get the right answers from the kernel32 version. Looking through random crash reports I see some "SP2" kernel32.dll's at 5.1.2600.6293 and some "SP3" kernel32.dll's at 5.1.2600.5781. Looks like a fully-patched SP2 might actually be higher version than an old SP3 (but from a different code branch), and I don't trust that they'd both have GetLogicalProcessorInformation. I am leaning towards installing the hook on all XP's. (In reply to Masatoshi Kimura [:emk] from comment #14) > It might bring some other bugs (such as bug 1136775 or bug 1138070) into > genuine XP SP3 environments. I really doubt it was the hook code that caused those issues.

Presumably, we can get the symbols for all these kernel32.dll versions and check. Probably not worth the effort, though.

And backed out because I have a better idea. Let's test GetProcAddress. https://hg.mozilla.org/integration/mozilla-inbound/rev/b7cdf1cf0939
(I would not normally check the result of that GetModuleHandle, but if this may go to m-r, let's be paranoid)

https://hg.mozilla.org/integration/mozilla-inbound/rev/b429cedbba79 I stepped through the code on machines with and without the export.
David, if that is ok with you, could you fill the uplift request so that we are ready? Thanks

Comment on attachment 8571773 [details] [diff] [review] Test for the missing export because we can't trust the version Please note, we'll also need to take bug 1138070 to make this fix complete. Approval Request Comment [Feature/regressing bug #]: bug 1023941 [User impact if declined]: Can't load FF on franken-installs of Windows XP that claim to be SP3 but have SP2 binaries [Describe test coverage new/current, TreeHerder]: [Risks and why]: This change itself should be low risk as it is scoped to just the installs that need it. However, for IME users, this change will take them from "can't load FF" to "can load, but can't use IME". To get those users all the way to "fixed" we will need bug 1138070. [String/UUID change made/needed]: none
