Hi ,
When i use below library call of OpenIPMI (1.4.19 or even 1.4.21) from
an application (linux 2.4.22), i notice a memory leak. The call is
made in an application loop. Mem leak tools
point to the allocs in stand_ipmi_sensor_get_reading etc and the
absense of corresponding free.
The library call i make for my callback handler is:
ipmi_sensor_id_get_reading(ipmi_sensor_id_t sensor_id,
ipmi_sensor_reading_cb done,
void *cb_data)
In the libray this function, after some levels of nesting, calls:
stand_ipmi_sensor_get_reading() where info ptr is malloc'd.
In error cases ipmi_mem_free(info) is called immediately in these chain of
function calls.
In success cases it seems to be called when the operation
is done via: reading_get_done_handler.
Eg:
reading_get
`-sensor_done_check_rsp
`- reading_get_done_handler <-- ipmi_free_mem() here
However in cases like below, i dont see the done handler (free).
reading_get_start
`-sensor_done_check_rsp
Could this be a source of leak.
Any pointer on how to debug further, especially to check if the
asynchronous de-queued operations are completed and info ptr is freed?
do we need to throttle the rate of above get_reading handler
operation from application?
Thanks
Noor
