hi holger,
i would like to test it. but before i can do that, i need to know what
ressource are actually counted.
The first step is to only count gsm_subscriber instances. E.g. start with a
fresh BSC.
- Do Location Updating Request procedure and see if "show subscriber cache" on
the telnet console is empty.
- Use "sms send EXTENSION TEXT" and see if subscriber cache is empty
afterwards
- Call one phone from another, hang up, see the subscriber cache. Currently
the called party (Mobile Terminated) will leak the gsm_subscriber due
the mncc_send implementation and the paging down there.
for example: a transaction holds one ressource, paging holds one
ressource, as well as a channel that is associated to that subscriber's
transaction.
what about sms? shold an object of "struct gsm_sms" be counted as one
ressource, or each sender/receiver within this structure, or all
together (one for the sms, one for the sender and one for the receiver)?
Currently it is just about getting subscr_get and subscr_put balanced, finding
out more "live leaks" later is the next thing.
Currently the branch is doing:
- Stops borrowing the gsm_subscriber to the lchan
- Fixes leaks in the vty_interface_layer3.c code for subscriber action
- Fixes a subscriber leak (actually two) in mncc_send.
if wanted I can attach the patches to this mail to ease reviewing.
