Description

I am trying to run an AOT compiled Hello World on aarch64 on Nvidia Shield TV android device. It always returns exit code 255. I ran the app with strace and got the following output:

It looks like the failure is caused by mmap failing with ENOMEM. Setting DOTNET_GCHeapHardLimit to lower values solves the issue.

I tried to find the root cause of the mmap failure but was not able to. Empirically I found that on this hardware, running the elf in an infinite bash loop that checks the exit code, setting DOTNET_GCHeapHardLimit to:

I tried to make a minimal C program that does a single mmap to reproduce the issue, but interestingly enough, it never fails, even with max long long int value.

That leads to the conclusion that the issue is caused not by just a single mmap, but by a combination of syscalls.

C program: ```c #include #include #include #include #include int main(int argc, char *argv[]) { size_t size = 0; if (sscanf(argv[1], "%zu", &size) != 1) { printf("invalid arg\n"); return 1; } printf("mapping %zu\n", size); void *ptr = mmap(NULL, size, PROT_NONE , MAP_PRIVATE | MAP_ANONYMOUS, -1, 0); if (ptr <= 0) { perror("mmap failed\n"); return 1; } else { printf("mmap succeeded\n"); return 0; } } ```

Reproduction Steps

With Android NDK r26b in PATH:

dotnet new console -o HelloWorld --aot
cd HelloWorld
dotnet publish -r linux-bionic-arm64 -p:DisableUnsupportedError=true -p:PublishAotUsingRuntimePack=true -p:StripSymbols=false
adb push ./bin/Release/net8.0/linux-bionic-arm64/publish/HelloWorld.dll /data/local/tmp/
adb shell /data/local/tmp/HelloWorld

Expected behavior

Should output Hello, World!

Actual behavior

Exit code 255 and strace shows mmap failed with ENOMEM

Regression?

No response

Known Workarounds

Setting DOTNET_GCHeapHardLimit to some small value. Since I'm running the code on an Android device, and the intended use is to run it via JNI from Java code, I can set env before doing a JNI call from Java.

Issue Details
### Description I am trying to run an AOT compiled Hello World on aarch64 on Nvidia Shield TV android device. It always returns exit code 255. I ran the app with `strace` and got the following output:

It looks like the failure is caused by `mmap` failing with `ENOMEM`. Setting `DOTNET_GCHeapHardLimit` to lower values solves the issue. I tried to find the root cause of the `mmap` failure but was not able to. Empirically I found that on this hardware, running the elf in an infinite bash loop that checks the exit code, setting `DOTNET_GCHeapHardLimit` to: - 64+GB is guaranteed to fail - above 40GB fails every second run of the binary - 32+GB fails every 20th run or so - Setting it below 32GB doesn't fail I tried to make a minimal C program that does a single `mmap` to reproduce the issue, but interestingly enough, it never fails, even with max long long int value. That leads to the conclusion that the issue is caused not by just a single `mmap`, but by a combination of syscalls.
C program: ```c #include #include #include #include #include int main(int argc, char *argv[]) { size_t size = 0; if (sscanf(argv[1], "%zu", &size) != 1) { printf("invalid arg\n"); return 1; } printf("mapping %zu\n", size); void *ptr = mmap(NULL, size, PROT_NONE , MAP_PRIVATE | MAP_ANONYMOUS, -1, 0); if (ptr <= 0) { perror("mmap failed\n"); return 1; } else { printf("mmap succeeded\n"); return 0; } } ```
### Reproduction Steps With Android NDK r26b in PATH: ```sh dotnet new console -o HelloWorld --aot cd HelloWorld dotnet publish -r linux-bionic-arm64 -p:DisableUnsupportedError=true -p:PublishAotUsingRuntimePack=true -p:StripSymbols=false adb push ./bin/Release/net8.0/linux-bionic-arm64/publish/HelloWorld.dll /data/local/tmp/ adb shell /data/local/tmp/HelloWorld ``` ### Expected behavior Should output `Hello, World!` ### Actual behavior Exit code 255 and `strace` shows `mmap` failed with `ENOMEM` ### Regression? _No response_ ### Known Workarounds Setting `DOTNET_GCHeapHardLimit` to some small value. Since I'm running the code on an Android device, and the intended use is to run it via JNI from Java code, I can set env before doing a JNI call from Java. ### Configuration - dotnet 8.0.100 - Android TV, Android 11, 4.9.141-tegra-gfad87a91fd8 - Nvidia Shield TV 2015, `NVIDIA/foster_e/foster:11/RQ1A.210105.003/7825230_3167.5736:user/release-keys` - aarch64 - No such issue on other Android devices I have ``` [ro.build.characteristics]: [tv] [ro.build.date]: [Sun Oct 16 20:55:18 PDT 2022] [ro.build.date.utc]: [1665978918] [ro.build.description]: [foster_e-user 11 RQ1A.210105.003 7825230_3167.5736 release-keys] [ro.build.display.id]: [RQ1A.210105.003.7825230_3167.5736] [ro.build.fingerprint]: [NVIDIA/foster_e/foster:11/RQ1A.210105.003/7825230_3167.5736:user/release-keys] [ro.build.flavor]: [foster_e-user] [ro.build.host]: [mobile-u64-5308-d7000] [ro.build.id]: [RQ1A.210105.003] [ro.build.product]: [foster] [ro.build.system_root_image]: [true] [ro.build.tags]: [release-keys] [ro.build.type]: [user] [ro.build.user]: [NVIDIA] [ro.build.version.all_codenames]: [REL] [ro.build.version.base_os]: [] [ro.build.version.codename]: [REL] [ro.build.version.incremental]: [7825230_3167.5736] [ro.build.version.min_supported_target_sdk]: [23] [ro.build.version.ota]: [9.1.1(33.2.0.157)] [ro.build.version.preview_sdk]: [0] [ro.build.version.preview_sdk_fingerprint]: [REL] [ro.build.version.release]: [11] [ro.build.version.release_or_codename]: [11] [ro.build.version.sdk]: [30] [ro.build.version.security_patch]: [2022-04-05] ``` ### Other information Related to #85650

@dotnet/gc this looks the same as https://github.com/dotnet/runtime/issues/95257#issuecomment-1833251006. If it is, this is the second customer report.

hez2010 commented 8 months ago

It seems to be caused by W^X, try setting the environment variable DOTNET_EnableWriteXorExecute=0 and see if it resolves your issue.

This won't help. W^X is not applicable to AOT. DOTNET_EnableWriteXorExecute has no effect for AOT compiled binaries.

nikarh commented 8 months ago

As mentioned above, DOTNET_EnableWriteXorExecute=0 ./HelloWorld did not work. For now, I have only this workaround - DOTNET_GCHeapHardLimit=400000000 ./HelloWorld

+ @mangod9 For investigation. I think it would be good to ensure our device support is as wide as possible now that Native AOT makes it more appropriate to target niche devices.

mangod9 commented 8 months ago

@dotnet/gc this looks the same as #95257 (comment). If it is, this is the second customer report.

Is this a scenario where multiple GCs are being loaded within the process?

MichalStrehovsky commented 8 months ago

No, just one. The mmap fails earlier

mangod9 commented 8 months ago

Adding @janvorli since some fixes were done in this space in 9 around retrieving available virtual memory. Looks like the large reservation is failing.

janvorli commented 8 months ago

@nikarh is it possible that the maximum usable virtual memory size is limited on this device? What does ulimit -v show?

janvorli commented 8 months ago

Ah, I am sorry I've missed that you've tested creating a large mapping using a C test program. Then the virtual memory size is not limited and the problem would be caused by used physical memory amount.

janvorli commented 8 months ago

Actually, the reservation that causes the failure is also just virtual memory, so it is strange that your testing C program and dotnet app behaves differently.

nikarh commented 8 months ago

Unfortunately not the case:

$ ulimit -v
unlimited
janvorli commented 8 months ago

@nikarh one more idea - can you please share the output of cat /proc/sys/vm/overcommit_memory? If that was 2, it would explain the failure. That setting would indicate that the OS would deny any requesting more virtual memory space than there is the size of swap + certain percentage of total physical memory (cat /proc/sys/vm/overcommit_ratio would dump that percentage). Although if that was the culprit, I would expect the allocation to fail even when you've set the DOTNET_GCHeapHardLimit slightly below the 32GB, unless you have a really large swap.

Unfortunately, the device is not rooted, and the shell user lacks read permissions to /proc/sys/vm on this device.

mangod9 commented 2 months ago

Hey @nikarh, are you still hitting this issue for your scenario?

MichalStrehovsky commented 2 months ago

Hey @nikarh, are you still hitting this issue for your scenario?

We have several user reports related to the GC reserving huge amounts of memory on various devices with likely customized linux kernels. https://github.com/dotnet/runtime/issues/95257#issuecomment-1833251006 was the other one. Both are mmap failures. It would be nice if the GC could scale the reservation down to a more reasonable amount given the device - e.g. the other issue I linked seems to imply that if one attempts to reserve 256 GB twice, the second reservation is going to fail - i.e. the GC is doing something within the process that does not coexist very well with someone else also wanting to allocate memory (it's not clear to me how big is the total limit, but there apparently is a limit and the GC is pushing the process close to it).
