Unfortunatelly I've not followed the last two or three weeks commits (new semester started and so now I rarely have time to fix my personal bridge) but tonight I synched my tree and immediately noticed a rather nasty bug! [Using libbb/interface.c:1.24] # grep eth0 /proc/net/dev | xargs eth0:311708397 237346 1670 0 1789 1670 0 0 22580308 120297 0 0 0 102 0 0 # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:20:AF:7C:EA:B7 inet addr:10.0.0.1 Bcast:10.0.0.127 Mask:255.255.255.128 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:5 Base address:0x320 All values `ifconfig' is showing are `zeroed' -- I quickly looked at the last commits I missed and noticed that there were a commit relating to ifconfig, libbb/interface.c:1.23->1.24 (PatchSet 4338). I've reversed the patch and now everything is working again. I compared the get_name's return values from the 1.23 and 1.24 and quickly noticed that the new revision is leaving `p' right on the sep while the rev 1.23 was leaving it right on the starting of the values... 1-line, 1/3-minute patch attached :-)

I've found a possible bug in libbb/interface.c, in function if_readlist_proc(). This function calls get_name(), and passes as an argument 'name', a buffer of 16 bytes (IFNAMSIZ). The function get_name(), however, may use more than 16 bytes, when it is searching for aliases. Even if you don't have an alias interface, you can run into trouble if the interface has received more than 99999999 bytes, in which case the space between the interface name and the rx stats disappears, as in the /proc/net/dev example below: wan0.200:264573315 462080 ... In this case get_name() correctly identifies the interface name as "wan0.200", but to do that it uses 18 bytes of the 'name' buffer, which could lead to an unpredictable error. A simple solution would be to increase the size of the buffer:

IPV6 support to busybox. This patch does the following: * Add IPv6 support to libbb * Enable IPv6 interface address display * Add IPv6 config option * Adds ping6, an adaptation of the ping applet for IPv6 * Adds support routines for ping6: - xgethostbyname2 - create_icmp6_socket * Adds ifconfig support for IPv6 * Add support IPv6 to netstat * Add IPv6 support to route Thanks Bart!

2001-04-19This has two patches. First it moves interface.c to libbb (it isEric Andersen
support code after all). It also contains a patch from Larry Doolittle that removes two instances of "strlen([^)]*) *- *1", un-shadows two variables, relaxes requirement for a sprintf(3) that returns number of bytes written, and eliminates a duplicate subroutine.
