There are 3 ways BusyBox can handle buffer allocations:
|
||
|
|
- Use malloc. This costs code size for the call to xmalloc.
|
||
|
|
- Put them on stack. For some very small machines with limited stack
|
||
|
|
space, this can be deadly. For most folks, this works just fine.
|
||
|
|
- Put them in BSS. This works beautifully for computers with a real
|
||
|
|
MMU (and OS support), but wastes runtime RAM for uCLinux. This
|
||
|
|
behavior was the only one available for BusyBox versions 0.48 and
|
||
|
|
earlier.

dmalloc support:

----------------
|

|
|
This enables compiling with dmalloc ( http://dmalloc.com/ )
|

|
|
which is an excellent public domain mem leak and malloc problem
|
||
|
|
detector. To enable dmalloc, before running busybox you will
|
||
|
|
want to properly set your environment, for example:
|
||
|
|
export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
|
||
|
|
The 'debug=' value is generated using the following command
|
||
|
|
dmalloc -p log-stats -p log-non-free -p log-bad-space -p log-elapsed-time \
|
||
|
|
-p check-fence -p check-heap -p check-lists -p check-blank \

Electric-fence support:
|
||
|
|
-----------------------
|
||
|
|
This enables compiling with Electric-fence support. Electric
|
||
|
|
fence is another very useful malloc debugging library which uses
|
||
|
|
your computer's virtual memory hardware to detect illegal memory
|
||
|
|
accesses. This support will make BusyBox be considerable larger
|
||
|
|
and run slower, so you should leave this option disabled unless
|

|
|
you are hunting a hard to find memory problem.
