The rest of the log seems to be the remainder of the (otherwise successful) client run. I think the SSL error message unexpected eof while reading:ssl/record/rec_layer_s3.c:321 in the logs was emitted by the client after the SSL connection failed.

Seen in, e.g., the internal tests:

I ran a 50x grinder here and got one iteration with 10/10 failed tests. The other 4 iterations passed.

The text was updated successfully, but these errors were encountered:

@cjjdespres is looking into this failure.

cjjdespres · 2024-04-17T14:00:54Z

I haven't been able to reproduce this locally yet, unfortunately, but from what I've seen it only seems to fail on rhel8 and cent8. Could this be related to https://github.ibm.com/runtimes/infrastructure/issues/9147#issuecomment-76212158? It seems as though the server is crashing in this call:

openj9/runtime/compiler/runtime/Listener.cpp

Line 106 in b1c3564

ret = (*OSSL_accept)(ssl);

judging from the logs, anyway - the client fails to complete the SSL handshake here:

openj9/runtime/compiler/net/ClientStream.cpp

Line 259 in b1c3564

if ((*OSSL_connect)(ssl) != 1)

probably because of the server crash.

cjjdespres · 2024-04-17T15:14:30Z

~~Building openssl 3.0.7 from source did not appear to work.~~ I installed openssl 3.0.7 from EPEL on a RHEL 8.8 fyre VM and managed to reproduce the crash. It's crashing with an illegal instruction exception. Backtrace from gdb:

To reproduce, generate a cert/key pair with

openssl genrsa -out key.pem 2048

openssl req -new -x509 -sha256 -key key.pem -out cert.pem -days 365 -subj "/CN=localhost"

Then run jitserver -XX:JITServerSSLKey=key.pem -XX:JITServerSSLCert=cert.pem -Xjit:verbose={JITServer} to start the JITServer, and separately run java -XX:+UseJITServer -XX:JITServerSSLRootCerts=cert.pem -Xjit:verbose={JITServer} -version.

The -Xjit:verbose={JITServer} shows that the particular JDK I was using was built with OpenSSL 3.0.13 and was running with 3.0.7, as expected. I just grabbed one of the JDKs from a failing internal nightly build - I imagine this will fail with master as well.

cjjdespres · 2024-04-17T15:24:29Z

Actually, I don't think I tested building OpenSSL 3.0.7 from source on RHEL 8.8, so maybe that would work as well.

mpirvu · 2024-04-17T15:25:16Z

@ymanton Is that instruction lxvb16x 32, 0, 8 valid on older P machines?

cjjdespres · 2024-04-17T15:36:56Z

I grepped through the openssl repo and that instruction does not appear in the code in the openssl-3.0.7 tag. Maybe it's from an EPEL patch? (It does appear in master, in the file named by gdb).

ymanton · 2024-04-17T15:53:20Z

@ymanton Is that instruction lxvb16x 32, 0, 8 valid on older P machines?

It's only supported on POWER 9 and later. The machine getting SIGILL is P8.

I don't think you'd see this if you built OpenSSL from source on the target machine or installed a package available from the repos the machine has access to.

Did you get your EPEL package from epel-8 or epel-9? RHEL 9 dropped support for P8 so all packages for RHEL 9 are going to be built for P9 as the baseline.

cjjdespres · 2024-04-17T15:56:02Z

I got it from epel-8.

cjjdespres · 2024-04-17T15:58:08Z

I'm fairly sure it's epel-8, anyway. This is on RHEL 8.8. The exact package is openssl3-3.0.7-5.el8.1.src.rpm.

ymanton · 2024-04-17T16:52:14Z

Do you see the exact same crash outside of a debugger?

From what I can tell of the openssl code, it expects SIGILL in some places because that's how it dynamically discovers which instructions are supported by the host: https://github.com/openssl/openssl/blob/openssl-3.0.7/crypto/ppccap.c

That code will check the auxvector¹ if it was built with that support, otherwise fall back to testing with SIGILL. You can check the contents of the auxvector by running something with LD_SHOW_AUXV=1 in your env, e.g.:

$ LD_SHOW_AUXV=1 openssl3 version | grep AT_HWCAP
AT_HWCAP:        true_le archpmu vsx arch_2_06 dfp ic_snoop smt mmu fpu altivec ppc64 ppc32
AT_HWCAP2:       vcrypto tar isel ebb dscr arch_2_07

The only discrepancy is that I don't see any of the functions in that code in your backtrace, and since you appear to have debug symbols available they wouldn't be hidden by inlining for example. Your backtrace looks like an operation is actually in progress. It could a bug, but I would think this stuff would have been thoroughly tested.

If you run it in gdb it will catch SIGILL so you should try outside of the debugger or get gdb to pass the signal on² to the program and see what happens.

ymanton · 2024-04-17T17:02:43Z

Actually don't bother with all that work, your problem looks like exactly this bug: openssl/openssl#19163

mpirvu · 2024-04-17T17:21:55Z

If I understand correctly, openssl 3.0.7 on Power has a bug which prevents us from running JITServer with encryption on Power 8 machines.

cjjdespres · 2024-04-17T17:57:20Z

If I understand correctly, openssl 3.0.7 on Power has a bug which prevents us from running JITServer with encryption on Power 8 machines.

The openssl 3.0.7 package that was recently installed on the rhel8/cent8 power test machines, at least.

Yes, it looks like it was fixed upstream in 3.3 and backported to 3.1, but I'm not sure why 3.0 didn't get it.

cjjdespres · 2024-04-22T16:14:05Z

Just to record it here - the problem seems to be that the epel-8 OpenSSL package (version 3.0.7) was patched to include some performance improvements for power 9 and up introduced into OpenSSL 3.1 and later versions, but was not patched to include a later bug fix that prevents this issue from occurring. @ymanton mentioned that he would raise an issue with Red Hat to try to resolve the problem.

ymanton · 2024-04-22T19:05:26Z

https://bugzilla.redhat.com/show_bug.cgi?id=2276143

ymanton · 2024-04-22T23:55:18Z

It looks like there is a openssl3-3.2.1-1.1.el8 package in the pipeline that should have a fix for this.

@cjjdespres you can download it here and test it on a VM if you're inclined.

You can see that it's crashing in libcrypto, and that particular test ran on rtj-rhel8le-svl-test-d8dvh-1.fyre.ibm.com.

openssl3-3.2.1-1.1.el8 is available on EPEL and is supposed to fix this.

These failures seem to have disappeared from the nightly builds, so it looks like @mpirvu was right about this being fixed. (I can't quite remember what the resolution was in the end, though). I think this can be closed for now.
