Hi, I've managed to build Mozilla's nss/jss on Android 2.2/API8/ndk-r4b at ubuntu 10.04. When I try to generate the testing certificates on the Android emulator, I got W/dalvikvm( 284): ReferenceTable overflow (max=512) W/dalvikvm( 284): Last 10 entries in JNI local reference table: I can generate an empty db : $ adb shell # cd /data/local/msm/emptydb # ls -l -rw------- app_32 app_32 229376 2010-08-17 01:23 cert9.db -rw------- app_32 app_32 1106 2010-08-17 01:23 pkcs11.txt -rw------- app_32 app_32 294912 2010-08-17 01:23 key4.db # I copied the above db files to my linux box, use desktop version of nss/jss, I can generate the testing certificates and use certutil to see the certificates. I am not familiar with the jss code, I looked at the jss java/c code(jss 4.3.1), I can not find the obvious leaks of "reference".
1)Is it possible to increase the size of ReferenceTable, let's say (max=51200) ? 2) Can someone point me a direction where is the leaks of references ? I've built fennec first by following the instructions at https://wiki.mozilla.org/Mobile/Fennec/Android and got nss/nspr libraries for ARMv5, then I untar the jss-4.3.1 at the same location as nss, made some changes to the config files and got libjss4.so for ARMv5. Here is a piece of source code : String dbdir = "/data/local/msm/emptydb"; String strPasswordFile = "/data/local/msm/passwords"; SetupDBs.initDB(dbdir, strPasswordFile); String[] strArgs = { dbdir, strPasswordFile, "12345", "macubuntu", "SHA-256/RSA", "JSSCATestCert", "JSSTestServerCert", "JSSTestClientCert" }; try { GenerateTestCert gtc = new GenerateTestCert(); gtc.doIt(strArgs); } catch(Exception e) { e.printStackTrace(); System.exit(1); } Here is the full output of "adb logcat" in more details: D/dalvikvm( 277): Trying to load lib /data/data/com.example.softtoken/lib/libjss4.so 0x43e37a78 D/dalvikvm( 277): Added shared lib /data/data/com.example.softtoken/lib/libjss4.so 0x43e37a78 D/dalvikvm( 277): No JNI_OnLoad found in /data/data/com.example.softtoken/lib/libjss4.so 0x43e37a78, skipping init D/dalvikvm( 277): Trying to load lib /data/data/com.example.softtoken/lib/libjss4.so 0x43e37a78 D/dalvikvm( 277): Shared lib '/data/data/com.example.softtoken/lib/libjss4.so' already loaded in same CL 0x43e37a78 I/System.out( 277): main: jss library loaded I/System.out( 277): ***FilePasswordCallback returns m1oZilla I/ActivityManager( 58): Displayed activity com.android.launcher/com.android.launcher2.Launcher: 47222 ms (total 47222 ms) W/dalvikvm( 277): ReferenceTable overflow (max=512) W/dalvikvm( 277): Last 10 entries in JNI local reference table: W/dalvikvm( 277): 502: 0x43e77c50 cls=[B (20 bytes) W/dalvikvm( 277): 503: 0x43e77c68 cls=[B (20 bytes) W/dalvikvm( 277): 504: 0x43e77c80 cls=Ljava/lang/String; (28 bytes) W/dalvikvm( 277): 505: 0x43e6c1b0 cls=Ljava/lang/Class; 'Lorg/mozilla/jss/pkcs11/PK11InternalTokenCert;' (164 bytes) W/dalvikvm( 277): 506: 0x43e77d40 cls=Lorg/mozilla/jss/pkcs11/PK11InternalTokenCert; (20 bytes) W/dalvikvm( 277): 507: 0x43e77e08 cls=[B (20 bytes) W/dalvikvm( 277): 508: 0x43e77e20 cls=[B (20 bytes) W/dalvikvm( 277): 509: 0x43e77e38 cls=Ljava/lang/String; (28 bytes) W/dalvikvm( 277): 510: 0x43e6c1b0 cls=Ljava/lang/Class; 'Lorg/mozilla/jss/pkcs11/PK11InternalTokenCert;' (164 bytes) W/dalvikvm( 277): 511: 0x43e77ef8 cls=Lorg/mozilla/jss/pkcs11/PK11InternalTokenCert; (20 bytes) W/dalvikvm( 277): JNI local reference table summary (512 entries): W/dalvikvm( 277): 104 of Ljava/lang/Class; 164B (4 unique) W/dalvikvm( 277): 103 of Ljava/lang/String; 28B (103 unique) W/dalvikvm( 277): 1 of [Ljava/lang/String; 28B W/dalvikvm( 277): 202 of [B 20B (202 unique) W/dalvikvm( 277): 1 of [Lorg/mozilla/jss/crypto/X509Certificate; 620B W/dalvikvm( 277): 101 of Lorg/mozilla/jss/pkcs11/PK11InternalTokenCert; 20B (101 unique) W/dalvikvm( 277): Memory held directly by tracked refs is 10248 bytes E/dalvikvm( 277): Failed adding to JNI local ref table (has 512 entries) I/dalvikvm( 277): "main" prio=5 tid=1 RUNNABLE I/dalvikvm( 277): | group="main" sCount=0 dsCount=0 s=N obj=0x4001d8e0 self=0xccb0 I/dalvikvm( 277): | sysTid=277 nice=0 sched=0/0 cgrp=default handle=-1345026008 I/dalvikvm( 277): | schedstat=( 3452339153 891172842 121 ) I/dalvikvm( 277): at org.mozilla.jss.CryptoManager.getPermCerts(Native Method) I/dalvikvm( 277): at com.example.softtoken.GenerateTestCert.doIt(GenerateTestCert.java:174) I/dalvikvm( 277): at com.example.softtoken.Softtoken.onCreate(Softtoken.java:53) I/dalvikvm( 277): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) I/dalvikvm( 277): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2627) I/dalvikvm( 277): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) I/dalvikvm( 277): at android.app.ActivityThread.access$2300(ActivityThread.java:125) I/dalvikvm( 277): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) I/dalvikvm( 277): at android.os.Handler.dispatchMessage(Handler.java:99) I/dalvikvm( 277): at android.os.Looper.loop(Looper.java:123) I/dalvikvm( 277): at android.app.ActivityThread.main(ActivityThread.java:4627) I/dalvikvm( 277): at java.lang.reflect.Method.invokeNative(Native Method) I/dalvikvm( 277): at java.lang.reflect.Method.invoke(Method.java:521) I/dalvikvm( 277): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) I/dalvikvm( 277): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) I/dalvikvm( 277): at dalvik.system.NativeStart.main(Native Method) I/dalvikvm( 277): E/dalvikvm( 277): VM aborting I/DEBUG ( 30): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** Thanks and regards. mli
