SECURITYFS_CREATE_FI(9) Security Framework SECURITYFS_CREATE_FI(9)NAMEsecurityfs_create_file - create a file in the securityfs filesystem
SYNOPSIS
struct dentry * securityfs_create_file(const char * name, mode_t mode,
struct dentry * parent,
void * data,
const struct file_operations * fops);
ARGUMENTS
name
a pointer to a string containing the name of the file to create.
mode
the permission that the file should have
parent
a pointer to the parent dentry for this file. This should be a
directory dentry if set. If this parameter is NULL, then the file
will be created in the root of the securityfs filesystem.
data
a pointer to something that the caller will want to get to later
on. The inode.i_private pointer will point to this value on the
open call.
fops
a pointer to a struct file_operations that should be used for this
file.
DESCRIPTION
This is the basic “create a file” function for securityfs. It allows
for a wide range of flexibility in creating a file, or a directory (if
you want to create a directory, the securityfs_create_dir function is
recommended to be used instead).
This function returns a pointer to a dentry if it succeeds. This
pointer must be passed to the securityfs_remove function when the file
is to be removed (no automatic cleanup happens if your module is
unloaded, you are responsible here). If an error occurs, the function
will return the erorr value (via ERR_PTR).
If securityfs is not enabled in the kernel, the value -ENODEV is
returned.
