===================================
Using flexible arrays in the kernel
===================================
Large contiguous memory allocations can be unreliable in the Linux kernel.
Kernel programmers will sometimes respond to this problem by allocating
pages with :c:func:`vmalloc()`. This solution not ideal, though. On 32-bit
systems, memory from vmalloc() must be mapped into a relatively small address
space; it's easy to run out. On SMP systems, the page table changes required
by vmalloc() allocations can require expensive cross-processor interrupts on
all CPUs. And, on all systems, use of space in the vmalloc() range increases
pressure on the translation lookaside buffer (TLB), reducing the performance
of the system.
In many cases, the need for memory from vmalloc() can be eliminated by piecing
together an array from smaller parts; the flexible array library exists to make
this task easier.
A flexible array holds an arbitrary (within limits) number of fixed-sized
objects, accessed via an integer index. Sparse arrays are handled
reasonably well. Only single-page allocations are made, so memory
allocation failures should be relatively rare. The down sides are that the
arrays cannot be indexed directly, individual object size cannot exceed the
system page size, and putting data into a flexible array requires a copy
operation. It's also worth noting that flexible arrays do no internal
locking at all; if concurrent access to an array is possible, then the
caller must arrange for appropriate mutual exclusion.
The creation of a flexible array is done with :c:func:`flex_array_alloc()`::
#include <linux/flex_array.h>
struct flex_array *flex_array_alloc(int element_size,
unsigned int total,
gfp_t flags);
The individual object size is provided by ``element_size``, while total is the
maximum number of objects which can be stored in the array. The flags
argument is passed directly to the internal memory allocation calls. With
the current code, using flags to ask for high memory is likely to lead to
notably unpleasant side effects.
It is also possible to define flexible arrays at compile time with::
DEFINE_FLEX_ARRAY(name, element_size, total);
This macro will result in a definition of an array with the given name; the
element size and total will be checked for validity at compile time.
Storing data into a flexible array is accomplished with a call to
:c:func:`flex_array_put()`::
int flex_array_put(struct flex_array *array, unsigned int element_nr,
void *src, gfp_t flags);
This call will copy the data from src into the array, in the position
indicated by ``element_nr`` (which must be less than the maximum specified when
the array was created). If any memory allocations must be performed, flags
will be used. The return value is zero on success, a negative error code
otherwise.
There might possibly be a need to store data into a flexible array while
running in some sort of atomic context; in this situation, sleeping in the
memory allocator would be a bad thing. That can be avoided by using
``GFP_ATOMIC`` for the flags value, but, often, there is a better way. The
trick is to ensure that any needed memory allocations are done before
entering atomic context, using :c:func:`flex_array_prealloc()`::
int flex_array_prealloc(struct flex_array *array, unsigned int start,
unsigned int nr_elements, gfp_t flags);
This function will ensure that memory for the elements indexed in the range
defined by ``start`` and ``nr_elements`` has been allocated. Thereafter, a
``flex_array_put()`` call on an element in that range is guaranteed not to
block.
Getting data back out of the array is done with :c:func:`flex_array_get()`::
void *flex_array_get(struct flex_array *fa, unsigned int element_nr);
The return value is a pointer to the data element, or NULL if that
particular element has never been allocated.
Note that it is possible to get back a valid pointer for an element which
has never been stored in the array. Memory for array elements is allocated
one page at a time; a single allocation could provide memory for several
adjacent elements. Flexible array elements are normally initialized to the
value ``FLEX_ARRAY_FREE`` (defined as 0x6c in <linux/poison.h>), so errors
involving that number probably result from use of unstored array entries.
Note that, if array elements are allocated with ``__GFP_ZERO``, they will be
initialized to zero and this poisoning will not happen.
Individual elements in the array can be cleared with
:c:func:`flex_array_clear()`::
int flex_array_clear(struct flex_array *array, unsigned int element_nr);
This function will set the given element to ``FLEX_ARRAY_FREE`` and return
zero. If storage for the indicated element is not allocated for the array,
``flex_array_clear()`` will return ``-EINVAL`` instead. Note that clearing an
element does not release the storage associated with it; to reduce the
allocated size of an array, call :c:func:`flex_array_shrink()`::
int flex_array_shrink(struct flex_array *array);
The return value will be the number of pages of memory actually freed.
This function works by scanning the array for pages containing nothing but
``FLEX_ARRAY_FREE`` bytes, so (1) it can be expensive, and (2) it will not work
if the array's pages are allocated with ``__GFP_ZERO``.
It is possible to remove all elements of an array with a call to
:c:func:`flex_array_free_parts()`::
void flex_array_free_parts(struct flex_array *array);
This call frees all elements, but leaves the array itself in place.
Freeing the entire array is done with :c:func:`flex_array_free()`::
void flex_array_free(struct flex_array *array);
As of this writing, there are no users of flexible arrays in the mainline
kernel. The functions described here are also not exported to modules;
that will probably be fixed when somebody comes up with a need for it.
