https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207497 --- Comment #1 from Andriy Voskoboinyk <avos@freebsd.org> --- (Probably, an inelegant) way to fix this issue: 1) lock the mutex; 2) count needed size by iterating over ic_head list; 3) allocate required memory; 4) copy all names to it (yet another iteration); 5) unlock the mutex; 6) pass the data to SYSCTL_OUT() 7) free the memory. --=20 You are receiving this mail because: You are the assignee for the bug.=
