Hi all,
I have came across, this kind of structure initialization for the first
time.
static const struct icmp_control icmp_pointers[NR_ICMP_TYPES + 1] = {
[ICMP_ECHOREPLY] = {
.output_entry = ICMP_MIB_OUTECHOREPS,
.input_entry = ICMP_MIB_INECHOREPS,
.handler = icmp_discard,
},
[1] = {
.output_entry = ICMP_MIB_DUMMY,
.input_entry = ICMP_MIB_INERRORS,
.handler = icmp_discard,
.error = 1,
},
[2] = {
.output_entry = ICMP_MIB_DUMMY,
.input_entry = ICMP_MIB_INERRORS,
.handler = icmp_discard,
.error = 1,
},
[ICMP_DEST_UNREACH] = {
.output_entry = ICMP_MIB_OUTDESTUNREACHS,
.input_entry = ICMP_MIB_INDESTUNREACHS,
.handler = icmp_unreach,
.error = 1,
},
[ICMP_SOURCE_QUENCH] = {
.output_entry = ICMP_MIB_OUTSRCQUENCHS,
.input_entry = ICMP_MIB_INSRCQUENCHS,
.handler = icmp_unreach,
.error = 1,
},
[ICMP_REDIRECT] = {
.output_entry = ICMP_MIB_OUTREDIRECTS,
.input_entry = ICMP_MIB_INREDIRECTS,
.handler = icmp_redirect,
.error = 1,
},
[6] = {
.output_entry = ICMP_MIB_DUMMY,
.input_entry = ICMP_MIB_INERRORS,
.handler = icmp_discard,
},
[7] = {
.output_entry = ICMP_MIB_DUMMY,
.input_entry = ICMP_MIB_INERRORS,
.handler = icmp_discard,
.error = 1,
},
[ICMP_ECHO] = {
.output_entry = ICMP_MIB_OUTECHOS,
.input_entry = ICMP_MIB_INECHOS,
.handler = icmp_echo,
},
[9] = {
.output_entry = ICMP_MIB_DUMMY,
.input_entry = ICMP_MIB_INERRORS,
.handler = icmp_discard,
.error = 1,
},
[10] = {
.output_entry = ICMP_MIB_DUMMY,
.input_entry = ICMP_MIB_INERRORS,
.handler = icmp_discard,
.error = 1,
},
[ICMP_TIME_EXCEEDED] = {
.output_entry = ICMP_MIB_OUTTIMEEXCDS,
.input_entry = ICMP_MIB_INTIMEEXCDS,
.handler = icmp_unreach,
.error = 1,
},
[ICMP_PARAMETERPROB] = {
.output_entry = ICMP_MIB_OUTPARMPROBS,
.input_entry = ICMP_MIB_INPARMPROBS,
.handler = icmp_unreach,
.error = 1,
},
[ICMP_TIMESTAMP] = {
.output_entry = ICMP_MIB_OUTTIMESTAMPS,
.input_entry = ICMP_MIB_INTIMESTAMPS,
