具体错误在
W/dalvikvm( 825): in Landroid/net/wifi/WifiNative;.scanResultsCommand ()Ljava/lang/String; (NewStringUTF)
这句提交了一个illegal的UTF8字符
Google半天,大意为Google的UTF8是经过修改过的,对一些UTF8字符不兼容。
在dalvik/vm/checkjni.c中做判断
/*
* Verify that "bytes" points to valid "modified UTF-8" data.
*/
static void checkUtfString(JNIEnv* env, const char* bytes, bool nullOk,
const char* func)
{
const char* origBytes = bytes;
if (bytes == NULL) {
if (!nullOk) {
LOGW("JNI WARNING: unexpectedly null UTF string/n");
goto fail;
}
return;
}
while (*bytes != '/0') {
u1 utf8 = *(bytes++);
// Switch on the high four bits.
switch (utf8 >> 4) {
case 0x00:
case 0x01:
case 0x02:
case 0x03:
case 0x04:
case 0x05:
case 0x06:
case 0x07: {
// Bit pattern 0xxx. No need for any extra bytes.
break;
}
case 0x08:
case 0x09:
case 0x0a:
case 0x0b:
case 0x0f: {
/*
* Bit pattern 10xx or 1111, which are illegal start bytes.
* Note: 1111 is valid for normal UTF-8, but not the
* modified UTF-8 used here.
*/
LOGW("JNI WARNING: illegal start byte 0x%x/n", utf8);
goto fail;
}
case 0x0e: {
// Bit pattern 1110, so there are two additional bytes.
utf8 = *(bytes++);
if ((utf8 & 0xc0) != 0x80) {
LOGW("JNI WARNING: illegal continuation byte 0x%x/n", utf8);
goto fail;
}
// Fall through to take care of the final byte.
}
case 0x0c:
case 0x0d: {
// Bit pattern 110x, so there is one additional byte.
utf8 = *(bytes++);
if ((utf8 & 0xc0) != 0x80) {
LOGW("JNI WARNING: illegal continuation byte 0x%x/n", utf8);
goto fail;
}
break;
}
}
}
return;
fail:
LOGW(" string: '%s'/n", origBytes);
showLocation(dvmGetCurrentJNIMethod(), func);
abortMaybe();
}
如果出现非法的UTF8字符就挂掉,这个也太狠了吧。
继续追踪根源,非法UTF8字符提交来自/frameworks/base/core/jni/android_net_wifi_Wifi.cpp的函数
// Send a command to the supplicant, and return the reply as a String
static jstring doStringCommand(JNIEnv *env, const char *cmd)
{
char reply[4096];
if (doCommand(cmd, reply, sizeof(reply)) != 0) {
return env->NewStringUTF(NULL);
} else {
return env->NewStringUTF(reply);
}
}
网上提出的解决方案是将非法头字符修正为“?”,将其他非法字符修正为“0x80”,patch后的函数如下:
// Send a command to the supplicant, and return the reply as a String
static jstring doStringCommand(JNIEnv *env, const char *cmd)
{
char reply[4096];
char* bytes;
if (doCommand(cmd, reply, sizeof(reply)) != 0) {
return env->NewStringUTF(NULL);
} else {
// Make sure reply only contains valid UTF-8 Characters
// This is borrowed from CheckJni.c
bytes = reply;
while (*bytes != '/0')
{
char utf8 = *bytes;
switch (utf8 >> 4) {
case 0x00:
case 0x01:
case 0x02:
case 0x03:
case 0x04:
case 0x05:
case 0x06:
case 0x07:
{
// Bit pattern 0xxx. No need for any extra bytes.
break;
}
case 0x08:
case 0x09:
case 0x0a:
case 0x0b:
case 0x0f:
{
/*
* Bit pattern 10xx or 1111, which are illegal start bytes.
* Note: 1111 is valid for normal UTF-8, but not the
* modified UTF-8 used here. + */
LOGW("JNI WARNING: illegal start byte 0x%x, changing to '?'/n", utf8);
//return env->NewStringUTF("AP"); //modify by rockie
*bytes = '?';
}
case 0x0e: {
// Bit pattern 1110, so there are two additional bytes.
utf8 = *(++bytes);
if ((utf8 & 0xc0) != 0x80) {
LOGW("JNI WARNING: illegal continuation byte 0x%x, changing to 0x80./n", utf8);
*bytes = 0x80;
}
// Fall through to take care of the final byte.
}
case 0x0c:
case 0x0d: {
// Bit pattern 110x, so there is one additional byte.
utf8 = *(++bytes);
if ((utf8 & 0xc0) != 0x80) {
LOGW("JNI WARNING: illegal continuation byte 0x%x, changing to 0x80./n", utf8);
*bytes = 0x80;
}
break;
}
}
bytes++;
}
return env->NewStringUTF(reply);
}
}
非常不解的是,patch后还是会有漏网的错误字符被提交到checkjni.c,导致系统挂掉

最后,小改下checkjni.c,注释掉goto fail。
不过,会不会有后遗症?

adb remount
adb pull /system/build.prop .
delete line ro.kernel.android.checkjni=1
adb push build.prop /system/.
adb shell reboot
if you build with user mode, you can't find this issue.

非常不解的是,patch后还是会有漏网的错误字符被提交到checkjni.c,导致系统挂掉

最后,小改下checkjni.c,注释掉goto fail。
不过,会不会有后遗症?

adb remount
adb pull /system/build.prop .
delete line ro.kernel.android.checkjni=1
adb push build.prop /system/.
adb shell reboot
if you build with user mode, you can't find this issue.
