For example, kexec_file_load() system call loads initramfs. In some netboot cases initramfs can be rather large. Allow to use up-to ssize_t bytes. The callers still can limit the maximum file size via buf_size. Link: https://lkml.kernel.org/r/20220527025535.3953665-1-pasha.tatashin@...

The following code example illustrates how to refer to a file by its object name. UNICODE_STRING uniName; OBJECT_ATTRIBUTES objAttr; RtlInitUnicodeString(&uniName, L"\\DosDevices\\C:\\WINDOWS\\example.txt"); // or L"\\SystemRoot\\example.txt" InitializeObjectAttributes(&obj...
Kernel-mode device drivers refer to a file by its object name. This name is \DosDevices together with the full path of the file. For example, the object name of the C:\Windows\Example.txt file is \DosDevices\C:\Windows\Example.txt. Then the object name is encapsulated into an OBJECT...
If you enabled the link-in-+t restriction, you can also try to create a symlink in /tmp (as a non-root user) pointing to a file that user has no read access to, then switch to some other user that has the read access (for example, root) and try to read the file via the link...
The following uses Hi3516D V300 as an example. Place the patches for the chip component in the corresponding path based on the path and naming rules for the patches of the chip component in kernel.mk in the kernel/linux/build repository. DEVICE_PATCH_DIR := $(OHOS_BUILD_HOME)/kernel/lin...

aFigure 7.2 summarizes the activities of the driver as it translates the example program from an ASCII source file into an executable object file. (If you want to see these steps for yourself, run GCC with the-voption.) The driver first runs the C preprocessor (cpp), which translates the...
