diffing kj4 - kj6 kernels

as kj6 is supposed to bring some bug fixes, I thought I'd check the kernel source.
there's not a huge amount of difference, but some looks interesting, hopefully of use to anyone wanting to building it.

Is there a new kernel source?
Sent from my GT-I9100

yes, kj6 is up,
the diffs are between kj4 and that kj6
to show the file differences (there's also some docs changes but they aren't really needed)

Where did you get the kernel source?

https://opensource.samsung.com/index.jsp
search for N7000
I presume the kkx build will be there under the other device code.

Maybe that diff solves my screen issue.
Just to explain, sometimes my screen does not wake up even if the phone is still running (long pressing the on/off button makes the phone vibrate which means that it is still working) and when I hard reboot it (8 seconds long on/off button press), it restarts and in the battery usage I can see that the phone has been awake for a long time instead of having been idle (when it happens, it is generally during the night).
As I am facing it globally (with both European stock and Hong Kong ROMs), I hope this kernel change corrects it.

I've seen the same thing a couple of times. Still haven't tested the KJ6 kernel to see the effect of those patches yet.

Actually thats spurred me onto testing the KJ6.. Initialtesting suggests Screen powers back up Much quicker from standby

KJ6, where did you get it?
Edit: I have Baseband version N7000XXKJ6 but Kernel N7000ZSKK1. Is is this version you are talking about?

no there's threads with the kj6 kernel, including the CF root thread.
I've just built kernel with the patches, working well so far.

Basically, what you did is you installed KJ6 kernel, rooted it and install the kernel you built?
If yes, do you mind, allowing me to download the kernel you built in order to use it?

Maybe any devs can adapt this for Magisk module?

Not possible,Xposed alters code while magisk alters files,you can't convert an Xposed module into a magisk module

[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 {
.flags = ANDROID_DLEXT_FORCE_LOAD | ANDROID_DLEXT_USE_LIBRARY_FD,
.library_fd = fd,
};
// 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????
android_dlopen_ext(path, RTLD_LAZY, &info);
}
Code:
// // native/jni/zygisk/entry.cpp
static void second_stage_entry() {
zygisk_logging();
ZLOGD("inject 2nd stage\n");
char path[PATH_MAX];
MAGISKTMP = getenv(MAGISKTMP_ENV);
int fd = parse_int(getenv(MAGISKFD_ENV));
snprintf(path, sizeof(path), "/proc/self/fd/%d", fd);
xreadlink(path, path, PATH_MAX);
android_dlextinfo info {
.flags = ANDROID_DLEXT_USE_LIBRARY_FD,
.library_fd = fd,
};
// 这里的dlopen并不会重新调用 zygisk_init, 这里是假的dlopen? 只是为了下一行的 dlclose?
// 为什么要这样做?
// Why do this?
self_handle = android_dlopen_ext(path, RTLD_LAZY, &info);
dlclose(self_handle);
close(fd);
unsetenv(MAGISKTMP_ENV);
unsetenv(MAGISKFD_ENV);
sanitize_environ();
hook_functions();
