Going through all this badly documented filesystem code is aweful. Could someone check the reallocblks code? Specifically this: /* * If the block range spans two block maps, get the second map. */ if (end_lvl == 0 || (idp = &end_ap[end_lvl - 1])->in_off + 1 >= len) { ssize = len; } else { #ifdef DIAGNOSTIC if (start_ap[start_lvl-1].in_lbn == idp->in_lbn) panic("ffs_reallocblk: start == end"); #endif ssize = len - (idp->in_off + 1); ^^^^^^^^^^^^^^^^^^^^^ This doesn't look right. It kinda seems to me that it should be (len - idp->in_off). if (bread(vp, idp->in_lbn, (int)fs->fs_bsize, &ebp)) goto fail; ebap = (ufs_daddr_t *)ebp->b_data; } I went through about 3 or 4 false alarms earlier today, and this could be another one. But if it is wrong it would fit the symptoms.... the first indirect block in the inode getting blown to bits. -Matt Matthew Dillon <dillon_at_backplane.com>Received on Sun Oct 16 2005 - 20:11:48 UTC
