| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch is based on work by tiggerswelt.net. They say: " We wanted udhcpc6 to release its IPv6-Addresses on quit (-R-commandline-option) which turned out to generate once again kind of garbage on the network-link. We tracked this down to two issues: - udhcpc6 uses a variable called "srv6_buf" to send packets to the dhcp6-server, but this variable is never initialized correctly and contained kind of a garbage-address - The address of the dhcp6-server is usually a link-local-address, that requires an interface-index when using connect() on an AF_INET6- socket We added an additional parameter for ifindex to d6_send_kernel_packet() and made d6_recv_raw_packet() to capture the address of the dhcp6-server and forward it to its callee.

* udhcp6: fix problems found running against dnsmasqDenys Vlasenko2017-03-272-3/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch is based on work by tiggerswelt.net. They say: " But when we tried to use dnsmasq on server-side, udhcpc6 was unable to forward the acquired address to its setup-script although the IPv6-Address had been assigned by the server as we could see via tcpdump. We traced this issue down to a problem on how udhcpc6 parses DHCPv6-Options: When moving to next option, a pointer-address is increased and a length buffer is decreased by the length of the option. The problem is that it is done in this order: option += 4 + option[3]; len_m4 -= 4 + option[3]; But this has to be switched as the length is decreased by the length of the *next* option, not the current one. This affected both - internal checks if a required option is present and the function to expose options to the environment of the setup-script. There was also a bug parsing D6_OPT_STATUS_CODE Options, that made dnsmasq not work as udhcpc6 thought it is receiving a non-positive status-code (because it did not parse the status-code as required in RFC 3315). In addition we introduced basic support for RFC 3646 (OPTION_DNS_SERVERS and OPTION_DOMAIN_LIST) and RFC 4704 (OPTION_CLIENT_FQDN). " Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* vi: avoid touching a new file with ZZ when no editing has been doneYousong Zhou2017-03-241-8/+8
| | | | | | | | | | | | | | This is the behaviour observed with standard vim and busybox vi of at least 1.22.1. It was changed with commit "32afd3a vi: some simplifications" which happened before 1.23.0. Mistyping filename on command line happens fairly often and it's better we restore the old behaviour to avoid a few unnecessary flash writes and sometimes efforts of debugging bugs caused by those unneeded stray files.

* switch_root: don't bail out when console doesn't existAndrei Gherzan2017-03-241-4/+6
| | | | | | | | | | | | | | | | | | | Busybox is very often used in initramfs at the end of which usually there is a switch_root to the actual rootfs. There are many cases where the console kernel argument is either just a placeholder (for example RaspberryPi uses serial0 and serial1) or configured as null to avoid any console messages - usually you would see such of a setup in production environments. Currently busybox bails out if can't open the console argument. If this happenes in initramfs and if the console=null for example, you get in a blind kernel panic. Avoid this by only warning instead of dying. function old new delta switch_root_main 371 368 -3 Signed-off-by: Andrei Gherzan <andrei@gherzan.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
