[Gdb] gdb system call support

[Agarwal, Amit (Amit)]

Hi,

        I have created a gdb (4.16.1) binary by statically linking all the libraries on an OpenBSD 3.2 system. I was able to successfully debug processes using this gdb on this OpenBSD system. Then I tried to run it on another system by mounting the gdb file system using NMS on another OpenBSD system. Gdb starts up fine but when I try to run a process I get the error "Bad System Call" and gdb exits automatically. My other Open BSD system which is showing the problem is a VPN/Firewall security gateway actually and has limited OpenBSD kernel components. I believe this security gateway has either some missing system calls or different version of system calls as required by gdb.

               
        I am looking for possible ways of debugging this issue. Is there any way I can get all the system calls used by gdb on an OpenBSD system or all the OpenBSD kernel components required. Also I am not sure if I am going into right direction to debug this problem and the problem will indeed be fixed by adding some kernel components in my security gateway.

        I will greatly appreciate any help with this issue.
thanks,
Amit
