Issue #3306 has been updated by dillon.
The ioctl code in the kernel needs to ensure that the buffer is zero-terminated, or it needs to zero-terminate the buffer itself, that it stores in if_description. Otherwise the strlen() on the read side will overrun the buffer if userland intentionally sets a description that is not zero-terminated. -Matt ---------------------------------------- Bug #3306: Add description support for ifconfig(8) http://bugs.dragonflybsd.org/issues/3306#change-14192 * Author: tuxillo * Status: In Progress * Priority: Normal * Category: Userland * Target version: 6.2 * Start date: 2021-11-12 ---------------------------------------- Is there a chance the 'ifconfig NIC description XXX' functionality will sync with the FreeBSD ? This is a fairly popular option. <pre> # ifconfig vlan1 description vm1-vlan ifconfig: description: bad value </pre> OpenBSD also has a similar capability[1], as NetBSD as well[2] Thanks! __ fn1. https://man.openbsd.org/ifconfig.8 fn2. https://man.netbsd.org/ifconfig.8 ---Files-------------------------------- 01-if-descr.patch (11.7 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
