2017-04-11fallocate: new appletDenys Vlasenko
NAME fallocate - preallocate or deallocate space to a file SYNOPSIS fallocate [-c|-p|-z] [-o offset] -l length [-n] filename fallocate -d [-o offset] [-l length] filename DESCRIPTION fallocate is used to manipulate the allocated disk space for a file, either to deallocate or preallocate it. For filesystems which support the fallocate system call, preallocation is done quickly by allocating blocks and marking them as uninitialized, requiring no IO to the data blocks. This is much faster than creating a file by filling it with zeroes. function old new delta fallocate_main - 179 +179 applet_names 2597 2606 +9 applet_main 1504 1508 +4 applet_suid 94 95 +1 applet_install_loc 188 189 +1 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-03-27udhcp6: fix releasingDenys Vlasenko
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.

2017-03-27udhcp6: fix problems found running against dnsmasqDenys Vlasenko
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>

2017-03-24vi: avoid touching a new file with ZZ when no editing has been doneYousong Zhou
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.

2017-03-24switch_root: don't bail out when console doesn't existAndrei Gherzan
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>
