2016-06-23ping: populate icmp_id field for "simple" ping tooJonas Danielsson
The ICMP RFC says that identifier and sequence number may be zero. Having them zero for a Echo message, along with a data of zero's as well will result in a Echo reply message with only zero's. Some NAT implementations seem to get the checksum wrong on these packages. Setting a checksum of 0x0 instead of 0xffff. Through NAT: Internet Control Message Protocol Type: 0 (Echo (ping) reply) Code: 0 Checksum: 0x0000 [incorrect, should be 0xffff] Identifier (BE): 0 (0x0000) Identifier (LE): 0 (0x0000) Sequence number (BE): 0 (0x0000) Sequence number (LE): 0 (0x0000) Data (56 bytes) Data: 000000000000000000000000000000000000000000000000... [Length: 56] Without NAT: Internet Control Message Protocol Type: 0 (Echo (ping) reply) Code: 0 Checksum: 0xffff [correct] Identifier (BE): 0 (0x0000) Identifier (LE): 0 (0x0000) Sequence number (BE): 0 (0x0000) Sequence number (LE): 0 (0x0000) [Request frame: 189] [Response time: 0.024 ms] Data (56 bytes) Data: 000000000000000000000000000000000000000000000000... [Length: 56] And this in turn will make some hardware MAC checksum offloading engines drop the packet. (This was seen with a Synopsis MAC, the same one used in for instance the stmmac Ethernet driver in the linux kernel.) This change can be seen as a workaround for bugs in other layers. But just setting an identifier for the Echo message packet will avoid prodding the hornets nest. function old new delta common_ping_main 424 500 +76 Signed-off-by: Jonas Danielsson <jonasdn@axis.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2016-06-06ntpd: retry initial DNS resolution (forever, no timeout for now).Denys Vlasenko
Some users start ntpd on boot, and don't babysit it. If it dies because DNS is not yet up and therefore NTP servers can't be found, users are not happy. Example behavior with a peer name which can't be resolved: ntpd: bad address 'qwe.rty.ghj.kl' ...5 sec... ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ntpd: bad address 'qwe.rty.ghj.kl' ...

2016-03-03dhcpc: Use client IP address as source address for DHCP renew/rebind messagesHans Dedecker
RFC2131 paragraph 4.1 states DHCP messages broadcast by a client prior to that client obtaining its IP address must have the source IP address field in the header set to 0. Request messages transmitted in renewing and rebinding state need to use the obtained IP address as source IP address in the header; this behavior lines up with other implementations like ISC dhcp client.

2016-03-01udhcpd: keep expired leases at startupChristian Lindeberg
Let udhcpd retain the information about expired leases when restarting so that the leases are reserved until they possibly become the oldest expired lease. This reduces the frequency of IP address changes for example when the DHCP server and a group of clients, who do not store and request their previously offered IP address across restarts, are collectively restarted and the startup order of the clients are not guaranteed.

2016-03-01ifupdown: allow duplicate interface definitionsNicolas Cavallari
This patch allow to have multiple interface definitions, much like Debian's ifupdown. More specifically, it removes the check for a duplicate definition, so the impact on binary size should be fairly minimal. This configuration: iface eth0 inet static address 192.168.0.15 netmask 255.255.0.0 gateway 192.168.0.1 iface eth0 inet static address 10.0.0.1 netmask 255.255.255.0 Will add two addresses to eth0 if ip is used. If ifconfig is used, the standards methods will likely not stack, but the administrator may still use the manual method. The DHCP method may work depending on the DHCP client in use. This is a fairly advanced feature for power users who knows what they are doing. There are not many other network configuration systems that allows multiple addresses on an interface.
