OsmocomBB mobile (host)
Description
The recent LUA integration code introduced the following
memory chunks unfreed at exit of mobile:
full talloc report on 'layer2 context' (total 8121 bytes in 9 blocks)
msgb contains 8120 bytes in 8 blocks (ref 0) 0x259e4d0
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x2651510
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x2652400
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x2650720
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x264fc10
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x2651f10
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x2651a20
Mobile Primitive contains 1160 bytes in 1 blocks (ref 0) 0x264f690
Isn't this feature optional?
Do we really need to keep that chunks all time?
As it turns out, a 'Mobile Primitive' is being allocated by mobile_prim_alloc()
on each Location Update request, but not freed...
Argh... I didn't think this through when going from stack based allocation to msgb.
I am almost away for today... can you try this? Will push it to gerrit tomorrow.
