Bug ID: 60461
Summary: SIGSEGV in SSLSocket.getInfos
Product: Tomcat 8

Hardware: PC
OS: Linux
Status: NEW
Severity: regression

JVM crash log
I recently upgraded my development setup from Tomcat 8.5.6 to 8.5.8 and
experiences a lot of SIGSEGV in Tomcat Native since then.
It always happens when calling SSLSocket.getInfos, but not on every call.
My HTTPS connector is configured this way :
<Connector port="8443" SSLEnabled="true"
protocol="org.apache.coyote.http11.Http11AprProtocol"
maxThreads="150" scheme="https" secure="true"
sslProtocol="TLS"
sslImplementationName="org.apache.tomcat.util.net.openssl.OpenSSLImplementation"
SSLCertificateFile="${catalina.home}/conf/certificate.crt"
SSLCertificateKeyFile="${catalina.home}/conf/privateKey.key"
server="Apache-Coyote/1.1"
URIEncoding="UTF-8">
<UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
</Connector>
I use Google Chrome 55 as HTTP client.
Debugging the project with Netbeans and attaching GDB to the java process, I
get the following stacktrace when SEGV :
__GI_raise (sig=6, sig@entry=6)
__GI_abort ()
os::abort(bool) ()
VMError::report_and_die() ()
JVM_handle_linux_signal ()
signalHandler(int, siginfo*, void*) ()
<signal handler called> ()
Java_org_apache_tomcat_jni_SSLSocket_getInfoS (e=0x7fc41861b1f8,
o=0x7fc37a6f2b68, sock=140478657220768, what=2)
So, the violation occurs on the last line of :
TCN_IMPLEMENT_CALL(jstring, SSLSocket, getInfoS)(TCN_STDARGS, jlong sock,
jint what)
{
tcn_socket_t *a = J2P(sock, tcn_socket_t *);
tcn_ssl_conn_t *s;
jstring value = NULL;
apr_status_t rv = APR_SUCCESS;
UNREFERENCED(o);
TCN_ASSERT(sock != 0);
s = (tcn_ssl_conn_t *)(a->opaque);
Please find attached the JVM crash log.
To debug, I configure native with :
./configure CC=${IDE_CC} CXX=${IDE_CXX} CFLAGS="-g3 -gdwarf-2"
CXXFLAGS="-g3 -gdwarf-2" --with-java-home=/usr/lib/jvm/java-8-oracle
--with-ssl=/home/lpenet/devoss/openssl-1.0.2j
and configure openssl 1.0.2j with the following command line :
./config no-shared -fPIC
