malloc: Enable assertions if UNIT_TEST is enabled

2023-10-11T17:22:29+00:00

dlmalloc has some sanity checks it performs on free() which can help detect
memory corruption. However, they are only enabled if DEBUG is defined before
including common.h. Define DEBUG earlier if UNIT_TEST is enabled so that
assertions are enabled in sandbox.

spl: Use SYS_MALLOC_F instead of SYS_MALLOC_F_LEN

2023-10-06T18:38:12+00:00

Use the new SPL/TPL/VPL_SYS_MALLOC_F symbols to determine whether the
malloc pool exists.

dlmalloc: Add support for SPL_SYS_MALLOC_CLEAR_ON_INIT

2023-09-05T02:53:46+00:00

To support SPL_SYS_MALLOC_CLEAR_ON_INIT, we have to modify
#ifdef CONFIG_SYS_MALLOC_CLEAR_ON_INIT
to #if CONFIG_IS_ENABLED(SYS_MALLOC_CLEAR_ON_INIT)

dlmalloc: Fix a warning with clang-15

2023-03-22T19:22:48+00:00

With clang-15 we now will get warnings such as:

warning: a function declaration without a prototype is deprecated in all
versions of C [-Wstrict-prototypes]

And it is easy enough to address this warning here, as we aren't
concerned with re-syncing with an upstream.

test: Support testing malloc() failures

2022-09-29T20:07:58+00:00

It is helpful to test that out-of-memory checks work correctly in code
that calls malloc().

Add a simple way to force failure after a given number of malloc() calls.

Fix a header guard to avoid a build error on sandbox_vpl.

malloc: Annotate allocator for valgrind

2022-04-11T14:00:30+00:00

This annotates malloc and friends so that valgrind can track the heap. To
do this, we need to follow a few rules:

* Call VALGRIND_MALLOCLIKE_BLOCK whenever we malloc something
* Call VALGRIND_FREELIKE_BLOCK whenever we free something (generally after
  we have done our bookkeeping)
* Call VALGRIND_RESIZEINPLACE_BLOCK whenever we change the size of an
  allocation. We don't record the original request size of a block, and
  neither does valgrind. For this reason, we pretend that the old size of
  the allocation was for 0 bytes. This marks the whole allocaton as
  undefined, so in order to mark all bits correctly, we must make the whole
  new allocation defined with VALGRIND_MAKE_MEM_DEFINED. This may cause us
  to miss some invalid reads, but there is no way to detect these without
  recording the original size of the allocation.

In addition to the above, dlmalloc itself tends to make a lot of accesses
which we know are safe, but which would be unsafe outside of dlmalloc. For
this reason, we provide a suppression file which ignores errors ocurring in
dlmalloc.c

malloc: add SPDX license identifiers

2021-06-23T12:45:03+00:00

The original code is in the public domain. Licenses/README states that the
general license for U-Boot is GPL 2.0+. So we can mark the malloc code as
GPL 2.0+ too.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.
