Bug ID: 235096
Summary: [patch] usr.bin/write broken capabilities checking
Product: Base System
Version: 12.0-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: fulle...@over-yonder.net

patch
In r306761 when write(1) was capsicumized, a call to setutxent() was added to
load up the utx db before entering capabilities mode. However, the other
setutxent() calls in later functions were left in place, so the actual
getutx*() calls would still fail, making write unable to find any users.
-CURRENT presumably needs a similar patch. Attach patch applies cleanly to
-CURRENT, but I've only tested on stable/12.
