Bug 15336 – Tracking a crasher with proxy usage (ssh -D) socks

• Component: New Bugs
• Status: RESOLVED INVALID

[William Coldwell]

Certain websites are crashing Safari at the end of rendering a page, but only when used through a tunnel (haven't been able to test VPN, just ssh -D socks).

Currently searching for a smaller test case.

Please attach a recent crash report.

I'm 90% sure this will be due to a bug in CFNetwork that leads to a crash when visiting HTTPS sites over a SOCKS proxy.  Please post a crash log so that this can be verified.

Thread 3 Crashed:
0   <<00000000>> 	0xffff8c74 __memcpy + 1236 (cpu_capabilities.h:189)
1   com.apple.CFNetwork            	0x90fae204 _PerformSOCKSv5PostambleHandshake_NoLock + 1224

looks like bdash is on the money.  The sites that trigger are https.

It's been here for a while, since I was hitting it but assuming that it was webkit growing pains.

Is that when viewing an https:// site?  Can you attach the full crash log entry please?

crash report

This is created by going to https://www.juniper.com
However, I noticed that going to https://www.warped.com won't trigger it.
The Amazon S3 page would only make it crash after the page was rendered, or at least most of it.

I can duplicate this 100% on either PPC or x86 with 10.4.10 (haven't tried leopard yet).

My configuration is ssh -D 12345 somemachinewithsshd.warped.com and with Network configuration set to Proxy Socks 5 on 127.0.0.1 port 12345.

This does not happen with Camino or Firefox, but does happen on Safari, WebKit nightly, and OmniWeb (sneakypeek).

As mentioned, this is not a bug in WebKit but in the underlying CFNetwork framework.  It is tracked in radar as <rdar://problem/4323043>.  I'll close this bug as invalid as it has nothing to do with WebKit.
