Here it is:
(gdb) l *recv_func+0x8c
0x17094 is in recv_func (drivers/staging/rtl8712/rtl8712_recv.c:1004).
999 r8712_free_recvframe(orig_prframe, pfree_recv_queue);
1000 goto _exit_recv_func;
1001 }
1002 _exit_recv_func:
1003 return retval;
1004 }
1005
1006 static int recvbuf2recvframe(struct _adapter *padapter, struct
sk_buff *pskb)
1007 {
1008 u8 *pbuf, shift_sz = 0;
I don't think this means the relevant call is the one at line 999. I
think it is an earlier call, after r8712_validate_recv_frame. Here's
the disassembly:
/* check the frame crtl field and decache */
retval = r8712_validate_recv_frame(padapter, prframe);
17070: e1a00004 mov r0, r4
17074: e1a01005 mov r1, r5
17078: ebfffffe bl 17bc0 <r8712_validate_recv_frame>
if (retval != _SUCCESS) {
1707c: e3500001 cmp r0, #1
r8712_free_recvframe(orig_prframe, pfree_recv_queue);
goto _exit_recv_func;
}
}
/* check the frame crtl field and decache */
retval = r8712_validate_recv_frame(padapter, prframe);
17080: e1a06000 mov r6, r0
if (retval != _SUCCESS) {
17084: 0a000005 beq 170a0 <recv_func+0x98>
/* free this recv_frame */
r8712_free_recvframe(orig_prframe, pfree_recv_queue);
17088: e1a00005 mov r0, r5
1708c: e1a01007 mov r1, r7
17090: ebfffffe bl 166e8 <r8712_free_recvframe>
r8712_free_recvframe(orig_prframe, pfree_recv_queue);
goto _exit_recv_func;
}
_exit_recv_func:
return retval;
}
17094: e1a00006 mov r0, r6
