| * Support translating ICMP errors.Lorenzo Colitti2013-04-127-46/+331
| | | | | | | | | | | | | | | | | | When receiving ICMPv6 messages from IPv6-only nodes, use 255.0.0.<ttl> as a fake IPv4 source address. It's better than nothing. Bug: 8276725 Change-Id: Iae93f75764cb9cd875af9bb5f1862a0dce2c2fa7
| * Improve checksum calculation and address checkingLorenzo Colitti2013-04-125-80/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Add a function that calculates the checksum of all the packet components starting from the specified position. This simplifies the code a bit and makes it easier to translate nested packets like ICMP error messages. 2. Don't hardcode IP source and destination addresses. This is required to translate ICMP error messages. Bug: 8276725 Change-Id: I2cae45683ae3943e508608fd0a140180dbc60823
| * Pass around packet data instead of fdsLorenzo Colitti2013-04-129-467/+383
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code calls all the translation functions one after another, accumulating the translated packet into local variables on the stack and calling writev() at the end. This does not allow calling the translation functions re-entrantly, which is needed, for example, to translate ICMP errors (which contain the packet that caused them). Define a clat_packet type to wrap the array of iovecs and an enum of packet positions. Also clean up the code a bit: get rid of a fair bit of duplicated code (though there is still some left), get rid of some redundant memcpy statements, fix style issues, etc. Bug: 8276725 Change-Id: Ib58d2348894e82275234fc67dbdb1f82753f204f

| | * Treat the options as part of the TCP header.Lorenzo Colitti2013-04-124-82/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the code and makes UDP and TCP look the same. It will also make it easier to implement nested translation in the future because there will only be one iovec array entry for the transport layer header, regardless of whether we are translating UDP or TCP and regardless of the presence of options. Also get rid of a couple of memcpy statements by pointing to the original data instead. Bug: 8276725 Change-Id: I6a702aefdf3a070eedfc6f7d3ebec21880ecc22b

| | * Pass in the length to pseudo checksum functionsLorenzo Colitti2013-04-094-33/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the pseudo-header checksum calculation functions get the transport layer length from the IP header. This requires that the length be known at IP header construction time, which does not allow transport layer translation functions to change the length of the packet later. Have the transport functions pass in the size directly. Bug: 8276725 Change-Id: I76a93f5e66181bec21d68f779c68c54090a77c33

| * | Configure the interface before bringing it upLorenzo Colitti2013-03-271-8/+9
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, clatd brings the clat4 interface up before assigning its IPv4 address. This can cause a race condition, because as soon as the interface comes up, the framework notices and reads the interface configuration into the LinkProperties. If this happens before the IPv4 address is configured, then the framework ends up thinking clat4's IPv4 address is 0.0.0.0/0. Fix this by configuring the address before the interface is brought up. Currently the framework does not use this address for anything, so this is purely cosmetic, but it could make debugging more confusing.

| | * Make clatd a bit more robust when started by netd.Lorenzo Colitti2013-03-022-12/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. When started from netd, DNS lookups (used to detect the NAT64 prefix) fail because ANDROID_DNS_MODE=local. Unset it. 2. Only add the SIGTERM handler just before starting the event loop. Otherwise, if clatd hangs before the event loop is started (e.g., when #1 happens), it can't be stopped. While I'm at it, add a couple of logging statements. Change-Id: Ie24b37e34b729ce6cd3769b5d64348f2c1b9627d

| | | | | | | | | | | | | | | | | | - Change the IPv4 address to 192.0.0.4. This is one of the IPv4 addresses reserved by IANA for DS-Lite, so it's close enough. - Change the IPv6 IID to ::464. The current code uses an IID in the IANA reserved range. Change-Id: I6039f13efc7d20c433b03cd322fc82a3a45b84cf

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently clatd accepts all netlink messages without validating that they come from the kernel. This could allow another app to spoof these messages. Fix this by connecting the socket to the kernel so that no other process can send it messages.

|/ | | | | | | | | | | | | | This software provides the nat 4->6 translation needed for the "clat" part of the 464xlat standard. It is needed for better IPv4 application support while on an IPv6-only mobile network connection using 464xlat's nat64 (such as T-Mobile's IPv6 trial).
