The idea to write this guide came up on - the #kernelnewbies IRC channel (see http://www.kernelnewbies.org/), - when Jeff Garzik explained the use of procfs and forwarded me a - message Alexander Viro wrote to the linux-kernel mailing list. I - agreed to write it up nicely, so here it is. - - - - I'd like to thank Jeff Garzik - jgarzik@pobox.com and Alexander Viro - viro@parcelfarce.linux.theplanet.co.uk for their input, - Tim Waugh twaugh@redhat.com for his Selfdocbook, - and Marc Joosen marcj@historia.et.tudelft.nl for - proofreading. - - - - Erik - - - - - - - - Introduction - - - The /proc file system - (procfs) is a special file system in the linux kernel. It's a - virtual file system: it is not associated with a block device - but exists only in memory. The files in the procfs are there to - allow userland programs access to certain information from the - kernel (like process information in /proc/[0-9]+/), but also for debug - purposes (like /proc/ksyms). - - - - This guide describes the use of the procfs file system from - within the Linux kernel. It starts by introducing all relevant - functions to manage the files within the file system. After that - it shows how to communicate with userland, and some tips and - tricks will be pointed out. Finally a complete example will be - shown. - - - - Note that the files in /proc/sys are sysctl files: they - don't belong to procfs and are governed by a completely - different API described in the Kernel API book. - - - - - - - - Managing procfs entries - - - This chapter describes the functions that various kernel - components use to populate the procfs with files, symlinks, - device nodes, and directories. - - - - A minor note before we start: if you want to use any of the - procfs functions, be sure to include the correct header file! - This should be one of the first lines in your code: - - - -#include <linux/proc_fs.h> - - - - - - - Creating a regular file - - - - struct proc_dir_entry* create_proc_entry - const char* name - mode_t mode - struct proc_dir_entry* parent - - - - - This function creates a regular file with the name - name, file mode - mode in the directory - parent. To create a file in the root of - the procfs, use NULL as - parent parameter. When successful, the - function will return a pointer to the freshly created - struct proc_dir_entry; otherwise it - will return NULL. describes how to do something useful with - regular files. - - - - Note that it is specifically supported that you can pass a - path that spans multiple directories. For example - create_proc_entry("drivers/via0/info") - will create the via0 - directory if necessary, with standard - 0755 permissions. - - - - If you only want to be able to read the file, the function - create_proc_read_entry described in may be used to create and initialise - the procfs entry in one single call. - - - - - - - - Creating a symlink - - - - struct proc_dir_entry* - proc_symlink const - char* name - struct proc_dir_entry* - parent const - char* dest - - - - - This creates a symlink in the procfs directory - parent that points from - name to - dest. This translates in userland to - ln -s dest - name. - - - - - Creating a directory - - - - struct proc_dir_entry* proc_mkdir - const char* name - struct proc_dir_entry* parent - - - - - Create a directory name in the procfs - directory parent. - - - - - - - - Removing an entry - - - - void remove_proc_entry - const char* name - struct proc_dir_entry* parent - - - - - Removes the entry name in the directory - parent from the procfs. Entries are - removed by their name, not by the - struct proc_dir_entry returned by the - various create functions. Note that this function doesn't - recursively remove entries. - - - - Be sure to free the data entry from - the struct proc_dir_entry before - remove_proc_entry is called (that is: if - there was some data allocated, of - course).

Such functions have - to be initialised after the procfs file is created by setting - the read_proc and/or - write_proc fields in the - struct proc_dir_entry* that the - function create_proc_entry returned: - - - -struct proc_dir_entry* entry; - -entry->read_proc = read_proc_foo; -entry->write_proc = write_proc_foo; - - - - If you only want to use a the - read_proc, the function - create_proc_read_entry described in may be used to create and initialise the - procfs entry in one single call. - - - - - - Reading data - - - The read function is a call back function that allows userland - processes to read data from the kernel. The read function - should have the following format: - - - - - int read_func - char* buffer - char** start - off_t off - int count - int* peof - void* data - - - - - The read function should write its information into the - buffer, which will be exactly - PAGE_SIZE bytes long. - - - - The parameter - peof should be used to signal that the - end of the file has been reached by writing - 1 to the memory location - peof points to. - - - - The data - parameter can be used to create a single call back function for - several files, see . - - - - The rest of the parameters and the return value are described - by a comment in fs/proc/generic.c as follows: - - -
- - You have three ways to return data: - - - - - Leave *start = NULL. (This is the default.) - Put the data of the requested offset at that - offset within the buffer. Return the number (n) - of bytes there are from the beginning of the - buffer up to the last byte of data. If the - number of supplied bytes (= n - offset) is - greater than zero and you didn't signal eof - and the reader is prepared to take more data - you will be called again with the requested - offset advanced by the number of bytes - absorbed. This interface is useful for files - no larger than the buffer. - - - - - Set *start to an unsigned long value less than - the buffer address but greater than zero. - Put the data of the requested offset at the - beginning of the buffer. Return the number of - bytes of data placed there. If this number is - greater than zero and you didn't signal eof - and the reader is prepared to take more data - you will be called again with the requested - offset advanced by *start. This interface is - useful when you have a large file consisting - of a series of blocks which you want to count - and return as wholes. - (Hack by Paul.Russell@rustcorp.com.au) - - - - - Set *start to an address within the buffer. - Put the data of the requested offset at *start. - Return the number of bytes of data placed there. - If this number is greater than zero and you - didn't signal eof and the reader is prepared to - take more data you will be called again with the - requested offset advanced by the number of bytes - absorbed. - - - -
- - - shows how to use a read call back - function. - - - - - - - - Writing data - - - The write call back function allows a userland process to write - data to the kernel, so it has some kind of control over the - kernel. The write function should have the following format: - - - - - int write_func - struct file* file - const char* buffer - unsigned long count - void* data - - - - - The write function should read count - bytes at maximum from the buffer. Note - that the buffer doesn't live in the - kernel's memory space, so it should first be copied to kernel - space with copy_from_user. The - file parameter is usually - ignored. shows how to use the - data parameter. - - - - Again, shows how to use this call back - function. - - - - - - - - A single call back for many files - - - When a large number of almost identical files is used, it's - quite inconvenient to use a separate call back function for - each file. A better approach is to have a single call back - function that distinguishes between the files by using the - data field in struct - proc_dir_entry. First of all, the - data field has to be initialised: - - - -struct proc_dir_entry* entry; -struct my_file_data *file_data; - -file_data = kmalloc(sizeof(struct my_file_data), GFP_KERNEL); -entry->data = file_data; - - - - The data field is a void - *, so it can be initialised with anything. - - - - Now that the data field is set, the - read_proc and - write_proc can use it to distinguish - between files because they get it passed into their - data parameter: - - - -int foo_read_func(char *page, char **start, off_t off, - int count, int *eof, void *data) -{ - int len; - - if(data == file_data) { - /* special case for this file */ - } else { - /* normal processing */ - } - - return len; -} - - - - Be sure to free the data data field - when removing the procfs entry. - - - - - - - - - Tips and tricks - - - - - - Convenience functions - - - - struct proc_dir_entry* create_proc_read_entry - const char* name - mode_t mode - struct proc_dir_entry* parent - read_proc_t* read_proc - void* data - - - - - This function creates a regular file in exactly the same way - as create_proc_entry from does, but also allows to set the read - function read_proc in one call.
