Summary Tracking a crasher with proxy usage (ssh -D) socks

Reported 2007-10-01 15:39:19 PDT
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.

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?

Created attachment 16554 [details] 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.
