patch

Fix sudo sending a 2nd SIGINFO on ^T to processes, which is already handled by the kernel sending it to the entire controlling terminal's process group.

This patch has been written by Bryan Drewery <bdrewery@FreeBSD.org> and added on FreeBSD's ports tree since sudo 1.8.20 and is working as expected. Here is a link to patch's history on FreeBSD ports svn repo

Thanks, I've committed a variant of this diff as https://www.sudo.ws/repos/sudo/rev/29603b0a4315

It will be included in sudo 1.8.22

Comment 2 Todd C. Miller 2017-09-01 16:59:08 MDT

Fixed in sudo 1.8.21p1
