Hi im sorry, this is decompiled

hi,what is this?
file extension c

Click to expand...

Isn't that a file for VS2008 or higher with C-code? I'll check that for you

Checked that for you, and indeed it is decompiled C++. This is what it contains, but I don't know what we should do with this code? Maybe someone who knows C++ can make HSPL with this as a basis?

for hard spl you must to decompile spl first and than to reverse enginer it to make hard spl. I was try that but im not c++ or c programer

[Q] Wi-Fi Ad-Hoc mode & wpa_supplicant

I have tried all this wpa_supplicant files to fix ad-hoc connection on my gsi9001, but every time it is hanging on the obtaining ip. Please someone help me with trying on other roms to manage ad-hoc mod. correctly i have used I9001XXKP4 with cranium mod...

these are modules?

2-of them are zip installation and one is just wpa_supplicant module... the all meaning is to change wpa_supplicant module to see ad-hoc connections...

works this without hangign at obtaining ip ?

Actually it's hanging... but after restarting wifi i'ts getting connected...

I´m having some issues too with connection.
I use Crybernation, before always worked with other ROMs, but now it hangs on getting IP...
I changed scan_interval to 0 too, but nothing happens.
Those files are for? Just change them from mine?
Thanks!

ok now it's working simplest way to get ad hoc running is the ad hoc enabler app from the market

http://www.youtube.com/watch?v=MtqiHcC0x5E
First u need to have superuser and busybox installed
Then download "WiFi Ad Hoc enabler" from market and instal it
Open it and goto settings,tick for disable comparibility check
and then click on 1)Verify Prerequisites
it will ask for superuser permission click Allow
Then click on 2)enable adhoc wifi
it will ask u to restart wifi

Good morning.
I have also SGS Plus (I9001) with Gingerbread. XXKPS (Android 2.3.6) and Kernel 2.6.35.7-perf [email protected]#1.
I have also "WiFi Ad Hoc enabler" Ver. 1.8.3.
My problem is this:
I have an internet connection on my Netbook HP mini (internet key USB H3G Italian provider) and an DHCP method for IP adress my LAN (192.168.0.40 to 192.168.0.50, gateway 192.168.0.1 and subnet mask 255.255.255.0)
I share with an adhoc connection to another Laptop HP with Win 7 64 bits, and it work very well
I share my internet connection from my laptop with Windows XP by WIFI to my laptop Win7.
When i tried to connect my android on this lan, i see the connection, after try to connect and the windows XP PC crashed any time.
I didn' understand the reason of this crash.
If i connect first the Android phone and after the win7 laptop, all is good and i have a very fast connection (adhoc by DHCP)
If i connect first the Win7 laptop and after the android phone, the windows XP netbook crashed.
Can you please give me some indication ?
Important. i didn't have on my "WiFi Ad Hoc enabler" the settigs page, only the "about" page with information on the program.
Thanks in advance for your answers

Ask Microsoft why it happens...?
Sent from my GT-I9001 using XDA App

Hey, how to connect my phone to ad hoc? Im currently used BroodROM RC5 btw. Before this, i've tried wifi ad hoc enabler 1.8.4 but i got an error about ownership of supplicant.conf. I appreciate any help in thi9s regard.

[HELP] why Zygisk need to force dlopen /system/bin/app_process

1. Why use android_dlopen_ext in the first_stage_entry function to force open /system/bin/app_process?
2. Why dlclose immediately after dlopen in second_stage_entry? Why do it?
// native/jni/zygisk/entry.cpp
static void first_stage_entry() {
android_logging();
ZLOGD("inject 1st stage\n");
char path[PATH_MAX];
char buf[256];
char *ld = getenv("LD_PRELOAD");
if (char *c = strrchr(ld, ':')) {
*c = '\0';
strlcpy(path, c + 1, sizeof(path));
setenv("LD_PRELOAD", ld, 1); // Restore original LD_PRELOAD
} else {
unsetenv("LD_PRELOAD");
strlcpy(path, ld, sizeof(path));
}
// Force the linker to load the library on top of ourselves, so we do not
// need to unmap the 1st stage library that was loaded with LD_PRELOAD.
int fd = xopen(path, O_RDONLY | O_CLOEXEC);
// Use fd here instead of path to make sure inode is the same as 2nd stage
snprintf(buf, sizeof(buf), "%d", fd);
setenv(MAGISKFD_ENV, buf, 1);
struct stat s{};
xfstat(fd, &s);
android_dlextinfo info {

};
// 通过 inode 在 maps 中搜索 /sbin/magisk(app_process) 对应的内存区域
auto [addr, size] = find_map_range(path, s.st_ino);
if (addr && size) {
// 下面使用 android_dlopen_ext 重复加载 /sbin/magisk,
// 通过 reserved_addr 强制覆盖内存.
info.flags |= ANDROID_DLEXT_RESERVED_ADDRESS;
info.reserved_addr = addr;
// The existing address is guaranteed to fit, as 1st stage and 2nd stage
// are exactly the same ELF (same inode). However, the linker could over
// estimate the required size and refuse to dlopen. The estimated size
// is not accurate so size the size to unlimited.
info.reserved_size = -1;
}
setenv(INJECT_ENV_2, "1", 1);
// Force dlopen ourselves to make ourselves dlclose-able.
// After this call, all global variables will be reset.
// 重复加载 /sbin/magisk 到内存, 覆盖之后全局变量将被重置
// 这里为什么要强制 dlopen? 只是为了以后可以使用 dlclose 释放 zygisk 吗????
