crypto/x509: 0xb01dfacedebac1e crash on Mac OS X 10.8 #16473

bradfitz · 2016-07-22T16:58:12Z

The Go download page says we support as low as Mac OS X 10.8 (Mountain Lion), so I worked on resurrecting a 10.8 builder and found it fails to run tests:

This appears to be a portability problem in the C code that was added in https://golang.org/cl/20351. This pure C program fails with a segmentation violation at the same point (when calling CFEqual).

I don't know what this code does and I don't plan to look at this further.

Thanks, @ianlancetaylor.

@adg, @broady, for Go 1.7 we need to do one of:

update our minimum supported Mac version for Go 1.7,
document this regression in the release notes, to be fixed later,
fix the new C code,
or maybe just skip this new code path when running on old OS X versions

I'll work on testing OS X 10.9 to see if it's also affected, or whether it's just 10.8. (10.10, 10.11, and 10.12 seem fine)

hinman · 2016-07-23T03:28:07Z

I'll see if I can get a 10.8 build env and replicate, I think I know what is going on.

bradfitz · 2016-07-23T03:28:57Z

@hinman, email me (bradfitz at golang) and I can get you ssh access to a 10.8 VM if that would help.

adg · 2016-07-24T22:38:00Z

I'd like to try and support 10.8 if we can. It's only 4 years old.

hinman · 2016-07-25T03:10:49Z

The following fix works for me on 10.8.5 and 10.11.5

10.9 looks fine.

bradfitz · 2016-07-26T14:58:03Z

@josharian suggested we do something like https://golang.org/cl/25233 instead, using the old implementation for OS X 10.8, rather than changing the implementation this late in the Go 1.7 cycle.

CL https://golang.org/cl/25233 mentions this issue.

bradfitz · 2016-07-26T21:29:49Z

Per @josharian's comment, the submitted CL isn't enough. We need runtime detection of OS X version, not compile-time. Patchset 1 of https://golang.org/cl/25233 was better in retrospect, even though there's probably a cheaper way to query it than os/exec to sw_vers. @quentinmit, you know Mac APIs?

Or @nickoneill?

gopherbot · 2016-07-26T23:00:16Z

CL https://golang.org/cl/25281 mentions this issue.

https://golang.org/cl/25233 was detecting the OS X release at compile time, not run time. Detect it at run time instead.

andlabs · 2016-07-26T23:55:16Z

Just out of curiosity, what exactly is going on? The only other reference I see to this particular issue is another github project; is this a regression in 10.8? (For what it's worth, I have 10.8-10.10 VMs to test potential issues with as well.)

hinman · 2016-07-27T01:27:03Z

@andlabs I didn't look too deeply but I think this is a regression is 10.8. For whatever reason the CFData structure that is returned looks like it hasn't been initialized correctly, but there is no error set. The functions worked fine on 10.11 and 10.10.

bradfitz · 2016-07-27T03:16:02Z

I've opened #16508 to track fixing this more properly in Go 1.8. Thanks again to @hinman for a working fix. It was just too risky for this late in Go 1.7, especially without appropriate reviewers.
