This commit fixes the logging tag for ptracer command-line tool, which would show as "zygisk-core64", the one from libzygisk, and an out-of-bounds access in "allowed_fds" array, which then the readdir returned the "." and "..", the "parse_int" would return -1, and would try to access it in "allowed_fds" without checking if it is negative, or bigger, first.
This commit creates a new behavior in ReZygisk umounting system where it now ignores "/system/..." mounts, as umounting them generally leads to unbootable system.
This commit adds numerous improvements to the state of hidden'ility of ReZygisk, and also for compatibility. Recommended to check #111 for more information.
This commit improves the code for multiple files by making "read_string" function already make the string NULL-terminated, avoiding code duplication. Also for "companion.c" fixes an "if" where it would read "client_fd" and check if "fd" is equal to "-1", instead of "client_fd", also does some overall code improvements there like detaching the thread, avoiding memory leaks in the exit, of the thread itself.
This commit fixes an issue where one of the "malloc", a libc function to allocate dynamic memory, "if"s were checking its return against non-NULL instead of NULL, making it seem to have failed when it didn't.
Two counters for module loading and unloading are introduced in the commit a2e83ab348. To remove linker traces of libzygisk.so and Zygisk modules, we should reset them properly.
Reading the file `/proc/self/maps` is detectable by the target process.
Hence, we should cache scanned virtual maps after `libart.so` is loaded for later plt hooks in the target process.
Note that it is impossible to hide injecting trace of virtual memory maps from the hooked target process.
ReZygisk will only focus on removing its trace for approcess that are not hooked by modules.
1. fix typo vsdo -> vdso and allow this symbol to be not found, which is the case for the 32bit linkers on some devices
2. use soinfo_free to fully remove the soinfo record of libzygisk.so
3. set `soinfo.size = 0` to avoid the library being unmapped while removing its soinfo record
4. add more debug logs for troubleshooting
Relying on dlclose to unload libzygisk.so will block us to clean its trace in the solist.
This commit allows us to unmap libzygisk.so without using dlclose.
To call munmap, we use the function pthread_attr_setstacksize instead of pthread_attr_destroy, so that tail-call can still be applied here since it has the same signature as munmap.
This commit merges the pull request by JingMatrix that includes improvements for clangd users, fixes for devices which have llvm suffix in SoList related symbols, and improved hiding related to the SoList.
In Bionic linker, the `soinfo` structure has a field `next`, which points to the next loaded library in a linked list consisting of all loaded libraries.
Hence, an injected process can easily find all loaded libraries.
Previously in ReZygisk, module library records are hidden by setting the `pathname` field to be empty, which is futile but easier to detect.
Current idea of dropping record can be found in the following commit:
5d635e8c66
On Android 15+ in some devices, the symbol names of some static variables such as `solist`, has a `llvm` suffix in its exported name.
Current commit handles this case and close#63 as fixed.
To make `clangd` work properly, one needs to make symbolic links

This commit fixes 2 issues:
- service.sh of files were not being executed in parallel, a behavior described in: https://github.com/topjohnwu/Magisk/blob/master/docs/guides.md#boot-scripts . This was fixed by using "&" in the end of the command to execute the module's service.sh, telling the shell to not block.
- Gradle wrapper used in ReZygisk was old, causing failing CIs.
It also updates the NDK version to ensure we'll be operating smoothly.
This commit fixes the issue where "free" would be executed in a pointer which has garbage data, leading to crashes. This was fixed by setting to NULL, so that it's clean.
It also fixes the issue where Zygiskd messages for "DAEMON_SET_INFO" would not count the NULL-terminator, causing crashes.
This commit removes information given in the response of info command of "zygisk-ptrace64" or "zygisk-ptrace32" that leads to failing builds, as it is not exported from monitor.cpp.
This commit fixes the issue where the commit that added "pid" (pid_t) and "running" (bool) members to the "zygote_info" structure, a structure that stores the response given by Zygiskd about its state, wasn't added, leading to failing buildings.
