CFNetwork crash in CFURLRequestSetMainDocumentURL

I have received two strange crash reports from an iPad11,7 running iPadOS 15.1 and an iPad11,2 running iPadOS 15.2.

On both occasions, the crashed thread calls CFURLRequestSetMainDocumentURL, which in turn calls _dispatch_source_set_runloop_timer_4CF in libdispatch, after which the application crashes with SIGSEGV and SEGV_MAPERR.

The crashed thread's call stack is displayed below. Full crash logs are attached as well. What could this be?

I have received two strange crash reports …

Can you repost these crash reports but this time do the redaction as described in Posting a Crash Report? Your current redaction approach is causing difficulties at my end.

Share and Enjoy

Attached to this post are crash logs with better redaction / alignment.

This is probably worthy of a separate topic, but I do briefly want to mention that the iPadOS 15.2 crash log failed to symbolicate automatically, and is still not fully symbolicated. I had to manually download iOS 15.2 arm64 and arm64e symbols and run symbolication with the symbolicatecrash command line utility. Xcode 13.2 freezes when I try to symbolicate the crash log through the Devices and Simulators window, and apparently Xcode 13.2 did not include the 15.2 symbols. Perhaps this is a result of downloading Xcode 13.2 manually from the Apple Developer downloads website, which was required due to the App Store Xcode issue described here.

Attached to this post are crash logs with better redaction / alignment.

Thanks.

My best guess is this is a bug at our end. The crash was triggered by a memory access exception. The crashing thread looks like this:

Thread 20 Crashed:
0 … libdispatch.dylib … dispatch_source_set_timer + 36 …
1 … CFNetwork         … URLConnectionLoader::loadWithWhatToDo(NSURLRequest*, _CFCachedURLResponse const*, long, URLConnectionLoader::WhatToDo) + 1128 …
…
5 … libdispatch.dylib … _dispatch_call_block_and_release + 32 …

Frame 1 is CFNetwork code being called by Dispatch. I took a look at this code and it’s scheduling a timeout timer. Frame 0 shows Dispatch crashing while it tries to work with this timer. This strongly suggests that the timer that CFNetwork passed in is bogus, and so it’s some sort of object lifetime issue within CFNetwork.

Now, it’s always possible that there’s a bug in your app that’s triggering this. For example, you might have a memory management issue that just happens to trigger this problem. However, that seems unlikely. We’ve seen crashes very similar to this being reported in a wide variety of different apps.

Still, if you’re not already doing this routinely, I recommend that you run your app’s test suite with the standard memory debugging tools to see if that flushes out anything actionable.

Normally at this point I’d point you to a bug that Apple is using to track this. However, the bug situation here is kinda muddied, so I’m going to recommend that you file your own bug about this.

Please post your bug number, just for the record.

Gathered another crash log where the main thread state is also captured. It seems to have to do with multithreading + cookie management in CFNetwork. Does this help finding the cause?

Perhaps the issue is in PLCrashReporter, or in the interplay between PLCrashReporter and CFNetwork?

Perhaps.

Frankly, I don’t trust any crash reports other than Apple crash reports. See Implementing Your Own Crash Reporter for an explanation as to why.

Bug number is [FB10663350]

Thanks for that.

Digging into the crash report a little more, I can confirm that the specific crash is caused by CFNetwork calling dispatch_source_set_timer [1] with NULL in the first parameter. Indeed, if you write a tiny test project with this code:

dispatch_source_set_timer(NULL, 0, 0, 0);

frame 0 of the crash will exactly match the crash report [2]:

(lldb) disas -s 0x10274ac3c -c 9
libdispatch.dylib`_dispatch_source_set_runloop_timer_4CF:
    0x10274ac3c <+0>:  pacibsp 
    0x10274ac40 <+4>:  stp    x26, x25, [sp, #-0x50]!
    0x10274ac44 <+8>:  stp    x24, x23, [sp, #0x10]
    0x10274ac48 <+12>: stp    x22, x21, [sp, #0x20]

(lldb) p/a $x0
(unsigned long) $0 = 0x0000000000000000

This suggests that this isn’t memory corruption, which is more evidence to support my earlier guess is that is a bug in CFNetwork itself.

Debugging this without a reproducible case is going to be hard.

[1] Not _dispatch_source_set_runloop_timer_4CF! That is a bogus symbolication.

[2] Yeah, and it’s weird that LLDB is also mis-symbolicating this.

This came up in another context so I took a look at the state of the bug. The bug referenced above, FB10663350, was marked as a dup of another bug, (r. 26038149). That, in turn, was marked as fixed in an early iOS 16 release (16.1 I think). If you’re still seeing it on later iOS 16 builds or iOS 17, you should definitely file a new bug about it.

Please post your bug number, just for the record.

Just noticed the in another context was referring to my own post. I've reported a bug and the bug number is FB13447648.

This appears to be an issue on macOS 12.2.1 (21D62) too. Just received some crash logs from a customer that seems like it is the same crash signature (this is one of four different crashes that occured over the course of a week or so. Every crash has the same this basic signature):

It seems to somewhat be related to multiple threads initiating HTTP requests at once, as the crash seems to correlate to a log from our process which prints out some info about a HTTP request getting squashed (ie Mar 25 11:37:15 --- last message repeated 1 time ---)

Unfortunately I haven't found a reliable way to reproduce this yet.


However, after looking into this a bit further (and not knowing which version of libdispatch is included in macOS 12.2.1 (21D62)), from looking at the source for a version of libdispatch, it does seem to point to a null ptr deref is causing the crash (assuming x0: 0x0000000000000000 is getting passed in as first argument):

void
_dispatch_source_set_runloop_timer_4CF(dispatch_source_t ds,
		dispatch_time_t start, uint64_t interval, uint64_t leeway)
{
	// Don't serialize through the source queue for CF timers <rdar://13833190>
	_dispatch_source_set_timer(ds, start, interval, leeway, false);
}

DISPATCH_ALWAYS_INLINE
static inline void
_dispatch_source_set_timer(dispatch_source_t ds, dispatch_time_t start,
		uint64_t interval, uint64_t leeway, bool source_sync)
{
	if (slowpath(!ds->ds_is_timer) ||
			slowpath(ds_timer(ds->ds_refs).flags & DISPATCH_TIMER_INTERVAL)) {
		DISPATCH_CLIENT_CRASH(ds, "Attempt to set timer on a non-timer source");
	}
    ...
}

Id guess the offset of ds_is_timer in the dispatch_source_t struct happens to be 0x58, which is causing the KERN_INVALID_ADDRESS at 0x0000000000000058.

The crash in _dispatch_source_set_runloop_timer_4CF seems back in iOS 18.0 but with a different stack trace:
