After a binary update from 8.2-RC2 to 8.2-RC3 I can no longer create directories on my external USB HDD. The filesystem is fat32 and the drive is manually mounted using "mount_msdosfs -o large". Writing, editing and deleting files is still possible. But even when I write files to the HDD, dmesg reports errors "g_vfs_done():da0s1[WRITE(offset=- ... , length=16384)]error = 5", although, the files are correctly written. It is even possible to delete directories but creating directories is impossible. The error does not occur on any fat16/fat32 USB flash disk, nor did it occur before updating to 8.2-RC3. Once the systems starts reporting these errors, it is impossible to unmount the HDD, and if I force it to unmount the HDD using "unmount -f" the systems freezes. Furthermore, these errors are reported continuously, after writing once to the HDD, and do never stop. The drive is working fine with other OSs and "fsck_msdosfs" reported a clean filesystem. ################################################# dmesg ################################################# Copyright (c) 1992-2011 The FreeBSD Project.

Hi, There has not been any significant changes in the USB area. I suspect that the failure is due to changes in other layers like CAM/SCSI/GEOM. --HPS
Responsible Changed From-To: freebsd-usb->freebsd-fs hselasky thinks this is unrelated to usb.
For bugs matching the following criteria: Status: In Progress Changed: (is less than) 2014-06-01 Reset to default assignee and clear in-progress tags. Mail being skipped
Created attachment 248592 [details] Proposed fix
This is caused by integer overflow in msdosfs_mkdir where the block number for the new directory is stored as int which overflows at 1 TiB.
