Apologies if this has been asked before: Yes, I’ve read all the disclaimers against accessing files in the kernel, but I want to set up a shared memory segment between a kernel module and one or more user processes, and /dev/shm seems like a good way to do that.
Given that, what’s the preferred way to access files within the kernel (specifically within a kernel module)? At the moment, I’m using filp_open() on module load to open the file (which seems to work), then: filp_close() to close the file * kern_path() to get the entry for the /dev/shm file vfs_unlink() to delete the /dev/shm file dput() to free the dentry path_put() to free the path …on module unload, and it hangs. Any suggestions what I’m doing wrong?
