Hello, there is an integer truncation in fs/xfs/libxfs/xfs_da_btree.c +2081 /* account for newly allocated blocks in reserved blocks total */ args->total -= dp->i_d.di_nblocks - nblks; with the types: uint32 -= uint64 - uint64 On a hardened kernel with grsecurity enabled, this leads to a fault. https://forums.grsecurity.net/viewtopic.php?f=3&t=4346&sid=3200600c0faaab4bf8779a95c549a737 Is this intentional and safe?
