Subject: [PATCH] ping: Fix unwanted bell on unreachable address
Upstream-status: commit effe9cd6c0a0269345cf0c092fe75aadf5f49102
Fixes: boo#1135118
Commit 4471ac629cf2603f4b8b45e042e072c992ce25a5 caused regression for IPv6
that ping -a IP6_ADDR beeps also on wrong address (i.e. when "Address
unreachable"):
$ ping -a -c1 fd00:1:1:1::15
PING fd00:1:1:1::15(fd00:1:1:1::15) 56 data bytes
From fd00:1:1:1::2 icmp_seq=1 Destination unreachable: Address unreachable
--- fd00:1:1:1::15 ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0m
It should only bell when ping returns correctly.
Another (fixed) regression was that ping after exit printed error "pipe N",
where N is number of counts. Error was result of code from ping_common.c:
printf("%spipe %d", comma, pipesize);
4471ac6 was wrong that code for sock->working_recverr == 1 should stay,
sock->working_recverr should be removed.
Thus changes:
* ping.c: put back "stronger filter" for raw socket but (unlike before
4471ac6) exit with 2 if setsockopt(ICMP_FILTER) fails
* ping6_common.c: put back setsockopt(IPV6_RECVERR), but (unlike before
4471ac6) exit with 2 if it fails
* ping6_common.c: remove ICMP6_FILTER_SETPASS calls. These caused error "pipe N".
* ping6_common.c: return 0 after acknowledge() in ping6_parse_reply
Fixes: 4471ac6 ("ping: Remove workaround for bug in IP_RECVERR on raw sockets")
