hi.
we have corrected a bug in ss7 stack when slc is not equal to 0.
File : mtp3.c
Function : set_routinglabel
Old code :
case SS7_ITU:
buf[0] = rl->dpc & 0xff;
buf[1] = ((rl->dpc >> 8) & 0x3f) | ((rl->opc << 6) &
0xc0);
buf[2] = (rl->opc >> 2) & 0xff;
buf[3] = ((rl->opc >> 10) & 0x0f) | (rl->sls &
0xf0);
return 4;
Modified code:
case SS7_ITU:
buf[0] = rl->dpc & 0xff;
buf[1] = ((rl->dpc >> 8) & 0x3f) | ((rl->opc << 6) &
0xc0);
buf[2] = (rl->opc >> 2) & 0xff;
buf[3] = ((rl->opc >> 10) & 0x0f) | ((rl->sls <<4) &
0xf0);
return 4;
Slc/sls should occupy upper nibble position as specified by ITU.
