User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:58.0) Gecko/20100101 Firefox/58.0 Build ID: 20171130160223 Steps to reproduce: 0 - on macOS, have more than one "network location" each with different configuration (eg. web proxyes or different networks) 1 - Have Firefox open, browsing any websites 2 - On the apple menu, go to Location, then change location (see https://apple.stackexchange.com/questions/298961/unable-to-change-network-location-while-firefox-is-open - Unable to change network location while Firefox is open) Actual results: - a message pops up with te text "firefox quit unexpectedly" - the network location is not changed - firefox does not actually crash - I have to close firefox, change the network location, then re-open firefox Expected results: the network should be changed. In my case, it changes the router address so I can switch network connection on the fly
I have been facing this issue for quite some time. To help diagnose further, If I reset my profile it stops happening. After resetting, I installed all my extensions, then also it did not happen. But, after few days of usage, it started happening again. I am ready to help diagnose this issue. Please let me know if I need to share any logs etc.

Tracy, this seems to be a duplicate of bug 1362238. I see the crash rate of bug 1362238 has decreased quite significantly over the last two months. Is there maybe a correlation with particular OS versions that could explain this?

Gus and deepak, please provide the crash report ID link in about:crashes so we can get the signature correctly associated with this bug. Stephen, definitely looks similar. Let's see what the signature is and go from there.

One additional information - I get this error only when Firefox is in the foreground. It does not happen if any other application has the focus.

Can you get the report ID by typing about:crashes in the URL bar of Firefox?
Flags: needinfo?(deepak)
The Firefox's crash reporter does not catch the error. Firefox continues to run despite the dialogue indicating that it has crashed. Network location does not change.
about:crashes - does not include these crashes.

I have some details regarding the "crash only happens when having firefox in foreground and focused": I have a multi-screen setup, and each screen has its own menubar. Each menubar shows the title of the current app of the corresponding screen. The crash only happens when I switch locations from the menubar IF the menubar shows Firefox as the current application. If I am using firefox in one screen only and then switch locations using the menubar from another screen, I have no error.

I had the same problem running in Yosemite. Upgraded a few days ago to High Sierra 10.13.2, Firefox 56.0.2 and Firefox no longer crashes when trying to switch network locations. However, the network location does NOT change, you simply do not get a crash. 1. Launch Firefox 2. With Firefox in foreground, select another location from the Apple Menu > Location menu. 3. Re-check network location to confirm it has not changed.

I'm able to reproduce this crash all the way back to the oldest build in mozregression. When the network location changes, the system calls HIS_XPC_SetNetworkLocation in HIServices. HIS_XPC_SetNetworkLocation forks our process. It is the new process that crashes when calling nano_reinit_lock in _malloc_fork_child. This happens in fork before exec. Markus, would it be possible to swizzle HIS_XPC_SetNetworkLocation and make it a no-op to avoid these crashes? Or are there concerns with this?

Hopper decompiles HIS_XPC_SetNetworkLocation to this: > void _HIS_XPC_SetNetworkLocation(int arg0, int arg1, int arg2) { > rbx = arg0; > r15 = *___stack_chk_guard; > r15 = *r15; > var_20 = r15; > if (rbx != 0x0) { > if (__isAppSandboxed() != 0x0) { > // ... > } else { > CFStringGetCString(rbx, &var_130, 0x100, 0x600); > rax = fork(); > if (rax != 0x0) { > waitpid(rax, &var_134, 0x0); > } else { > execl("/usr/sbin/scselect", "/usr/sbin/scselect"); > } > } > } > if (r15 != var_20) { > __stack_chk_fail(); > } > return; > } So it wants to run scselect and make the current process block until that's complete. I don't know what the reason for that is, but presumably there is a reason. I think it would be preferable if our process could fork without crashing. Do you have a complete stack for the crash? It looks like there was a similar problem in bug 1359624 which has been worked around, and it had crash stacks like this: https://crash-stats.mozilla.com/report/index/f44b50dc-7136-4f58-bf5d-bc0410180116 I think the problem there was that the random number generator wanted to free its RNG state, but used different allocators for allocating and freeing the state. Maybe we have a similar problem here.

The stack of the parent process (the Firefox process that is getting forked and does not crash) at the time of the crash is: (lldb) bt * thread #77, queue = 'com.apple.root.default-qos', stop reason = breakpoint 1.1 * frame #0: 0x00007fff92741a8b HIServices`HIS_XPC_SetNetworkLocation frame #1: 0x00007fff931071b0 HIToolbox`___ZL14SwitchLocationP13OpaqueMenuReft_block_invoke + 18 frame #2: 0x00007fffa918c524 libdispatch.dylib`_dispatch_call_block_and_release + 12 frame #3: 0x00007fffa91838fc libdispatch.dylib`_dispatch_client_callout + 8 frame #4: 0x00007fffa9192196 libdispatch.dylib`_dispatch_queue_override_invoke + 743 frame #5: 0x00007fffa91856b5 libdispatch.dylib`_dispatch_root_queue_drain + 476 frame #6: 0x00007fffa918548c libdispatch.dylib`_dispatch_worker_thread3 + 99 frame #7: 0x00007fffa93d25a2 libsystem_pthread.dylib`_pthread_wqthread + 1299 frame #8: 0x00007fffa93d207d libsystem_pthread.dylib`start_wqthread + 13 The stack of the child process (the Firefox process that crashes and was created by forking the parent process above) at the time of the crash is: Thread 0 Crashed:: Dispatch queue: com.apple.root.default-qos 0 libsystem_malloc.dylib 0x00007fff8f729f8a nano_forked_calloc + 11 1 libsystem_malloc.dylib 0x00007fff8f71bb90 malloc_zone_calloc + 78 2 libsystem_malloc.dylib 0x00007fff8f71c546 calloc + 49 3 libobjc.A.dylib 0x00007fff8cd67c12 class_createInstance + 133 4 libdispatch.dylib 0x00007fff8bb68ce1 _os_object_alloc_realized + 38 5 libxpc.dylib 0x00007fff8515dea9 _xpc_pipe_create + 61 6 libxpc.dylib 0x00007fff8517347d xpc_atfork_child + 117 7 libSystem.B.dylib 0x00007fff8c7dfb9f libSystem_atfork_child + 54 8 libsystem_c.dylib 0x00007fff8acbfee0 fork + 29 9 com.apple.HIServices 0x00007fff883720f7 HIS_XPC_SetNetworkLocation + 271 10 com.apple.HIToolbox 0x00007fff88ad4d99 ___ZL14SwitchLocationP13OpaqueMenuReft_block_invoke + 18 11 libdispatch.dylib 0x00007fff8bb6c700 _dispatch_call_block_and_release + 12 12 libdispatch.dylib 0x00007fff8bb68e73 _dispatch_client_callout + 8 13 libdispatch.dylib 0x00007fff8bb6bdc7 _dispatch_root_queue_drain + 935 14 libdispatch.dylib 0x00007fff8bb6ba1c _dispatch_worker_thread3 + 91 15 libsystem_pthread.dylib 0x00007fff8ab90a9d _pthread_wqthread + 729 16 libsystem_pthread.dylib 0x00007fff8ab8e3dd start_wqthread + 13 This does seem to indicate that we're crashing during memory allocation in fork in the child process. I'm not familiar with our allocator(s) and whether we use several different ones or not. Could it be that the OS uses libsystem_malloc.dylib as allocator during forking regardless of what allocators Firefox was using? And could it be that libsystem_malloc.dylib allocates memory regions in a way that results in memory regions stomping on each other that were fine with the allocators used by the parent Firefox process before? This is just a theory, but if this is the case I'm not sure we'll be able to fix this without swizzling HIS_XPC_SetNetworkLocation and skipping forking of our process. I'm also concerned that even if we fix this crash with the current state of Firefox, future changes to our allocator(s) may bring this crash back without warning and without clear correlation to the offending changes. It is true that there is probably a reason why the OS is trying to fork our process and call scselect. However, the child process is currently crashing before scselect is run and swizzling HIS_XPC_SetNetworkLocation would simply prevent the child process crash. I agree with you that avoiding swizzling would be preferable, if possible. Setting n-i in case you had any thoughts.

It has been a struggle to find a way to reproduce, but here's what finally worked for me:
1. Create two network locations in System Preferences. One for LAN, one for WiFi.
2. Create a new standard user account.
3. Log into standard user account.
4. Start Firefox and keep it in the foreground.
5. Click on the Apple icon in the top right corner (macOS menu bar).
6. Under "Location", switch from one location to the other.
7. If no macOS crash dialog opens, check /Applications/Utilities/Console.app for a crash report.
The macOS crash dialog failed to appear for me at first. I was able to make it appear by executing the following in Terminal:
> defaults write com.apple.CrashReporter DialogType crashreport
I'm able to reproduce this on 10.12.6 but there is no indication that this is OS version specific.

I haven't been successful in building libsystem to debug my own problem... Now, I do know that I've been able to build libsystem_malloc successfully in the past, so you should be able to do the same. The sources for 10.12.6 are in https://opensource.apple.com/tarballs/libmalloc/libmalloc-116.50.8.tar.gz. The source for the crashing function is in https://opensource.apple.com/source/libmalloc/libmalloc-116.50.8/src/nano_malloc.c.auto.html, and reads: static void * nano_forked_calloc(nanozone_t *nanozone, size_t num_items, size_t size) { malloc_zone_t *zone = (malloc_zone_t *)(nanozone->helper_zone); return zone->calloc(zone, num_items, size); } It would be good to know on which one of those two lines the crash happens. It's likely to be the second one, but just in case... That would suggest the nano zone is not initialized with a correct helper zone, so you'd probably want to check what's calling create_nano_zone and why that is happening.

Aha! I do get a crash with Nightly (I was trying release), in nano_reinit_lock, which reads: static void nano_reinit_lock(nanozone_t *nanozone) { int i; for (i = 0; i < nanozone->phys_ncpus; ++i) { _malloc_lock_init(&nanozone->band_resupply_lock[i]); } } The only way I can see this crashing itself (and not in _malloc_lock_init) is through a null deref, so nanozone being null. But this really shouldn't be happening. I can't figure out how to attach to that crashing process though...

Does attaching to the parent before the fork and setting "set follow-fork-mode child" work?

Will try to give this a shot tonight. This didn't work. The child process crashes before lldb can attach. I also went ahead and built gdb to see if I could use "set follow-fork-mode child" (comment 25) to debug the child process. Unfortunately, this doesn't work either. The child process still crashes. gdb ends in a hung state and needs to be killed via Terminal without providing any meaningful info. Setting n-i in case you had any other thoughts.

Ok, so this was fun. I wasn't able to build libmalloc successfully because I ran into simply too many errors to fix. I went ahead and patched libsystem_malloc.dylib instead (attached). Hopper Disassembler shows the original disassembly for nano_reinit_lock as: _nano_reinit_lock: 0000000000014d67 cmp dword [rdi+0x11288], 0x0 0000000000014d6e je loc_14d8b 0000000000014d70 xor eax, eax 0000000000014d72 mov dword [rdi+rax*4+0x11000], 0x0 0000000000014d7d inc rax 0000000000014d80 mov ecx, dword [rdi+0x11288] 0000000000014d86 cmp rax, rcx 0000000000014d89 jb loc_14d72 0000000000014d8b ret I changed the first nine bytes with a jmp back to itself at the start plus noop instructions, resulting in: _nano_reinit_lock: 0000000000014d67 jmp _nano_reinit_lock 0000000000014d6c align 16 0000000000014d70 xor eax, eax 0000000000014d72 mov dword [rdi+rax*4+0x11000], 0x0 0000000000014d7d inc rax 0000000000014d80 mov ecx, dword [rdi+0x11288] 0000000000014d86 cmp rax, rcx 0000000000014d89 jb loc_14d72 0000000000014d8b ret To run this, several steps need to be taken: 1. Restart the system and hold cmd-R during startup. 2. Once recovery mode starts, open a Terminal window from Utilities in the menu bar. 3. Enter "csrutil disable" to disable System Integrity Protection. This is required to replace the .dylib in /usr/lib/system. 4. Restart the system. 5. Save a backup copy of /usr/lib/system/libsystem_malloc.dylib. 6. Copy the attached .dylib to /usr/lib/system, replacing the existing one. IMPORTANT: do not move the original libsystem_malloc.dylib first without leaving a valid library in its place! This will leave your system in a broken state and you will have to recover by entering recovery mode by pressing cmd-R during startup. 7. Launch Firefox and reproduce the issue. The forked process will wait in nano_reinit_lock for a debugger to attach. 8. You can immediately restore the original libsystem_malloc.dylib file after launching Firefox to minimize possible issues from the modified library. The modified library will continue to be loaded in memory to debug Firefox. 9. IMPORTANT: restore the original libsystem_malloc.dylib as soon as possible, but imperatively before restarting your system or your system will not start (most likely because processes get forked during startup). 10. Don't forget to reenable System Integrity Protection by entering "csrutil enable" in Terminal in recovery mode (opposite of step 2 above).

Debugging showed that the crash occurs at offset +0xB (+11) into the function, confirming the offsets given in the crash dumps such as in comment 9: (lldb) si Process 12557 stopped * thread #1, queue = 'com.apple.root.default-qos', stop reason = EXC_BAD_ACCESS (code=2, address=0x10541f840) frame #0: 0x0000000105467d72 libsystem_malloc.dylib`nano_reinit_lock + 11 libsystem_malloc.dylib`nano_reinit_lock: -> 0x105467d72 <+11>: movl $0x0, 0x11000(%rdi,%rax,4) 0x105467d7d <+22>: incq %rax 0x105467d80 <+25>: movl 0x11288(%rdi), %ecx 0x105467d86 <+31>: cmpq %rcx, %rax Target 0: (firefox) stopped. (lldb) p $rdi (unsigned long) $5 = 4383107136 Offset +0xB into the function is part of the body of the for loop. So this isn't crashing due to a null nanozone, or we would have crashed at offset +0 into the function. $rdi holds the address for nanozone. Looking at the crash log in comment 9 again, there is additional info about the memory region around the crashing address: VM Regions Near 0x1041cb470: __DATA 00000001041ba000-00000001041bb000 [ 4K] rw-/rwx SM=COW /Applications/FirefoxDeveloperEdition.app/Contents/MacOS/libmozglue.dylib --> __LINKEDIT 00000001041bb000-00000001041d1000 [ 88K] r--/rwx SM=COW /Applications/FirefoxDeveloperEdition.app/Contents/MacOS/libmozglue.dylib MALLOC guard page 00000001041d1000-00000001041d2000 [ 4K] ---/rwx SM=NUL So we seem to be trying to access a memory location inside the __DATA region pertaining to FirefoxDeveloperEdition.app/Contents/MacOS/libmozglue.dylib, which seems to be readable and writable. This is about as far as I got. Could libmozglue.dylib be the culprit for some reason? One more thing that may or may not be helpful: I've noticed that I'm unable to reproduce the crash if I launch the Firefox.app/Contents/MacOS/firefox binary directly from Terminal. The crash only occurs if I launch the Firefox.app bundle by either double-clicking on it or calling 'open Firefox.app' in Terminal.

Per nano_malloc.c, a nanozone_t is supposed to come from create_nano_zone, which allocates them. That can't end up in a __DATA segment. So for some reason, nano_reinit_lock is being called with a normal malloc zone (ours), and that'd be the cause of all trouble. But I don't see how that function is supposed to end up being called with our zone... I guess I should try booting my mac and see for myself.

So, I can confirm this doesn't crash when running directly from Terminal, which makes using DYLD_* harder. So I tried something sneaky, which is to launch Firefox with open or from the icon, use the browser console to set the environment variable (Cc["@mozilla.org/process/environment;1"].getService(Ci.nsIEnvironment).set("DYLD_LIBRARY_PATH", "...")) and restart the browser (Services.startup.quit(Ci.nsIAppStartup.eAttemptQuit | Ci.nsIAppStartup.eRestart)), and successfully got a Firefox with the environment variable set (and I double checked, your patched libsystem_malloc.dylib was loaded). Unfortunately, it seems this is not happening after Firefox restarts either (confirmed by trying again with just a restart).

Found how things are going wrong: This all starts in _malloc_fork_child from https://opensource.apple.com/source/libmalloc/libmalloc-116.50.8/src/malloc.c.auto.html : // Called in the child process after fork() to resume normal operation. void _malloc_fork_child(void) { #if CONFIG_NANOZONE if (_malloc_initialize_pred && _malloc_engaged_nano) { nano_forked_zone((nanozone_t *)inline_malloc_default_zone()); } #endif return _malloc_reinit_lock_all(&__stack_logging_fork_child); } Both _malloc_initialize_pref and _malloc_engaged_nano are true (I /think/ the reason it doesn't happen when launching from the terminal or after a restart is that in that case _malloc_engaged_nano might be false). So nano_forked_zone is called with the result of inline_malloc_default_zone. The latter returns our zone, which we subtly set as the default zone. What does the former do ? The answer is in https://opensource.apple.com/source/libmalloc/libmalloc-116.50.8/src/nano_malloc.c.auto.html : void nano_forked_zone(nanozone_t *nanozone) { /* * Hobble the nano zone in the child of a fork prior to an exec since * the state of the zone can be made inconsistent by a parent thread while the * fork is underway. * All new allocations will be referred to the helper zone (which is more stable.) * All free()'s of existing nano objects will be leaked. */ mprotect(nanozone, sizeof(nanozone->basic_zone), PROT_READ | PROT_WRITE); nanozone->basic_zone.size = (void *)nano_size; /* Unchanged. */ nanozone->basic_zone.malloc = (void *)nano_forked_malloc; nanozone->basic_zone.calloc = (void *)nano_forked_calloc; nanozone->basic_zone.valloc = (void *)nano_valloc; /* Unchanged, already always obtained from helper zone. */ nanozone->basic_zone.free = (void *)nano_forked_free; nanozone->basic_zone.realloc = (void *)nano_forked_realloc; nanozone->basic_zone.destroy = (void *)nano_destroy; /* Unchanged. */ nanozone->basic_zone.batch_malloc = (void *)nano_forked_batch_malloc; nanozone->basic_zone.batch_free = (void *)nano_forked_batch_free; nanozone->basic_zone.introspect = (struct malloc_introspection_t *)&nano_introspect; /* Unchanged. */ nanozone->basic_zone.memalign = (void *)nano_memalign; /* Unchanged. */ nanozone->basic_zone.free_definite_size = (void *)nano_forked_free_definite_size; mprotect(nanozone, sizeof(nanozone->basic_zone), PROT_READ); } The definition of nanozone_t starts with a malloc_zone_t field named basic_zone (see https://opensource.apple.com/source/libmalloc/libmalloc-116.50.8/src/nano_zone.h.auto.html ). Practically speaking, since the function gets a pointer to our zone, it means this function is forcefully overwriting pointers in our zone. One of them now points to nano_introspect, which contains the pointer to nano_reinit_lock. We get back to _malloc_fork_child, which then calls _malloc_reinit_lock_all, which iterates over all zones, and calls the introspect.reinit_lock function, which, per the above, now points to nano_reinit_lock, with a pointer to the zone. nano_reinit_lock then expects that to be a nanozone, which it is not. Thus the crash. I'm surprised we haven't hit problems with this earlier...

> I /think/ the reason it doesn't happen when launching from the terminal or after a restart is that in that case _malloc_engaged_nano might be false.
I've now confirmed this hypothesis with "expr (int)malloc_engaged_nano()" in lldb attached to firefox launched from the terminal or after a restart. Which is interesting, because it means when we restart firefox after e.g. an upgrade, it doesn't run the same as when it's launched "normally".

Incidentally, this means we can make it happen when running from the Terminal by setting MallocNanoZone to 1 in the environment.

FWIW, when running "normally", MallocNanoZone is enabled through the "apple" argument to __malloc_init, from libSystem_initializer: https://opensource.apple.com/source/Libsystem/Libsystem-1238.60.2/init.c.auto.html That function is a constructor, so that all comes from the dynamic linker. No idea why restarting Firefox (which we do with NSTask) doesn't preserve that.

The dynamic linker gets that from the kernel, in data that follows envp: see the start function in https://opensource.apple.com/source/dyld/dyld-433.5/src/dyldInitialization.cpp.auto.html .

And the kernel engages it when the posix_spawn flags contain _POSIX_SPAWN_NANO_ALLOCATOR: see function exec_add_apple_strings in https://opensource.apple.com/source/xnu/xnu-3789.70.16/bsd/kern/kern_exec.c.auto.html . Unfortunately, there doesn't seem to be any public reference to that flag outside the xnu source. It must be set by some of the closed source stuff in OSX. At least launchctl seems to have a flag to disable the nano allocator for services. I don't know if we can do better than reexecuting ourselves with MallocNanoZone set to 0 in the environment when we detect that the nano allocator is engaged.

I grepped my OSX install for MallocNanoZone, and found this snippet in Xcode's Info.plist: <key>LSEnvironment</key> <dict> <key>MallocNanoZone</key> <string>0</string> </dict> which is practically speaking the equivalent of setting MallocNanoZone to 0 in the environment. I've validated that's what happens for Xcode when I launch it. I tried editing the Info.plist from my nightly directly, but that unfortunately didn't seem to work. I'll try see what happens with a try build.

Ok, this works if I edit Info.plist before I use the application the first time. OSX must cache it.

Note that instead of crashes, depending on how libmozglue.dylib is laid out, this could lead to memory corruption.

I added a comment in zone.c to point to the Info.plist, because it's not obvious there's some memory allocator related work around in there.

Comment on attachment 8947007 [details] Bug 1424709 - Force disable the OSX system "nano allocator". Approval Request Comment [Feature/Bug causing the regression]: Integration of the memory allocator on OSX [User impact if declined]: Crashes or memory corruptions on fork(). Fork() can be triggered by system libraries (like in the case of network location change like this bug) or by our code. At least in the case of this bug, the crash was not caught by our crash reporter, so we're also blind about those crashes. [Is this code covered by automated tests?]: No [Has the fix been verified in Nightly?]: Verified with local builds and try. [Needs manual test from QE? If yes, steps to reproduce]: See comment 21. [List of other uplifts needed for the feature/fix]: N/A [Is the change risky?]: No [Why is the change risky/not risky?]: The change effectively sets an environment variable that disables a system feature that we actually don't use, but that only causes problems when fork() is called. [String changes made/needed]: N/A Note that for esr52 the change in zone.c might not apply because I think the file moved between then and now, but it doesn't matter, it's only a comment.

I've tried to reproduce this issue using an affected Nightly build from 2017-12-11 on macOS 10.12 and Mac OS X 10.11, but unfortunately, I was not able to reproduce it. I followed the steps from comment 0 and comment 21. Hi taebox, I've seen that you already verified this bug on latest Nightly, could you please help us verifying this in latest Beta 59 (https://archive.mozilla.org/pub/firefox/candidates/) too, so we can close this bug, if there are no other concerns? Thanks in advance!

Comment on attachment 8947007 [details] Bug 1424709 - Force disable the OSX system "nano allocator". From IRC discussion with spohl, it's difficult to measure how many people are affected by this, but it's potentially large and a reasonably easy to hit situation. Since the patch is basically a one-liner, let's take this for ESR 52.7.0 as well.

It appears that the disabling of the Nano Allocator has broken WebVR on macOS (Bug 1454204). WebVR for macOS is going to release in FF60 but is now broken in FF60. I can confirm that reversing the changes in the info.plist file corrects it.

Hello Mike, Was there any other way to fix this without disabling the Nano Allocator? Otherwise, perhaps you may have some hints as to why this might break IPC with SteamVR on macOS? (see gfx/vr/openvr)

As mentioned in comment 35, the nano allocator was already disabled when running Firefox from the terminal, or after a restart (like, after an upgrade, or through about:support). So even reverting the change from this bug would still leave broken cases. Also, it's weird that this would break SteamVR... how is it initialized? do we spawn it from our process?

Very interesting... This may explain why WebVR for macOS never worked when I started Firefox from the command line, only when running from the app bundle. The code here interfaces with the Steam VR services: https://dxr.mozilla.org/mozilla-central/source/gfx/vr/openvr/src Essentially, some environment variables and configuration files are used to identify the location of a library which is dynamically loaded into our GPU process. The library then launches and communicates with some services running in other processes.

We are planning to move much of our code to a separate process, which would include the affected SteamVR / OpenVR code. Perhaps this separate process could be spawned with the nano allocator enabled..

Comment 69•6 years ago

It would be best to figure out why SteamVR/OpenVR fails when the nano allocator is disabled, because that doesn't make much sense. I guess, however, that this is not reproducing without have a Vive, so I won't be able to help there... at least not before the all hands, at which point we could find some time there to sit down and (try to) figure it out. In the meanwhile, what /might/ work is to set the MallocNanoZone environment variable in the GPU process, assuming it's a separate process.
