Aucbvax.5455 net.bugs.2bsd utzoo!decvax!ucbvax!dist2 Sat Dec 12 04:40:22 1981 IMPORTANT FIX: a bug in nami which may damage file systems The qcopy routine of nami.c sets i_count to 250 if it exceeds 255. This ultimately causes the quota node to be deallocated at a time when there are still valid pointers to it. A later attempt to change the node will cause the first block pointer of some other inode to be incremented or decremented. The fixes are:

diff kernel/sys/sys/nami.c.old kernel/sys/sys/nami.c 358,359d357 i_count) == 0) i_count = 250;

diff kernel/include/sys/inode.h.old kernel/include/sys/inode.h 37c37 int i_count; /* reference count */

These changes should be made to all tapes written before 12/12/81.
