The bug can be reproduced by running i386's dd binary on a 64-b= it kernel: $ /bin/dd if=3D/dev/zero of=3D1.file bs=3D1 count=3D1 oseek=3D1 conv=3Dspar= se 1+0 records in 1+0 records out 1 bytes transferred in 0.000235 secs (4263 bytes/sec) $ /root32/bin/dd if=3D/dev/zero of=3D1.file bs=3D1 count=3D1 oseek=3D1 conv= =3Dsparse dd: truncating 1.file: Not permitted in capability mode 1+0 records in 1+0 records out 1 bytes transferred in 0.000111 secs (9035 bytes/sec) There doesn't appear to be anything obviously wrong with the code in either= dd or kern_ftruncate, so I think it's a deeper capsicum bug. --=20 You are receiving this mail because: You are the assignee for the bug.=
