listen & accept sycalls not present in b32 ?

[hsultan at thefroid.net]

On Ubuntu 14.04 LTS I get :

sudo auditctl -a exit,always -F arch=b32 -S listen -S connect
Syscall name unknown: listen

however with b64 it works

Same with the accept syscall.

Is that expected ? How can I grab the 32bit calls then ?

Thanks,

Hassan
