The memcpy() in the warning is targeting bch_val, so I think the best fix is to correctly handle the different types. So just to have everything in front of me, here's a summary of what I'm seeing in the code: struct bkey { /* Size of combined key and value, in u64s */ __u8 u64s; ... }; /* Empty placeholder struct, for container_of() */ struct bch_val { __u64 __nothing[0]; }; struct bkey_i { __u64 _data[0]; struct bkey k; struct bch_val v; }; static inline void bch2_bkey_append_ptr(struct bkey_i *k, struct bch_extent_ptr ptr) { EBUG_ON(bch2_bkey_has_device(bkey_i_to_s(k), ptr.dev)); switch (k->k.type) { case KEY_TYPE_btree_ptr: case KEY_TYPE_btree_ptr_v2: case KEY_TYPE_extent: EBUG_ON(bkey_val_u64s(&k->k) >= BKEY_EXTENT_VAL_U64s_MAX); ptr.type = 1 << BCH_EXTENT_ENTRY_ptr; memcpy((void *) &k->v + bkey_val_bytes(&k->k), &ptr, sizeof(ptr)); k->k.u64s++; break; default: BUG(); } } So this is appending u64s into the region that start with bkey_i. Could this gain a u64 flexible array? struct bkey_i { __u64 _data[0]; struct bkey k; struct bch_val v; __u64 ptrs[]; }; Then the memcpy() could be just a direct assignment: k->ptrs[bkey_val_u64s(&k->k)] = (u64)ptr; k->k.u64s++; Alternatively, perhaps struct bkey could be the one to grow this flexible array, and then it could eventually be tracked with __counted_by (but not today since it expects to count the array element count, not a whole struct size): struct bkey { /* Size of combined key and value, in u64s */ __u8 u64s; ... __u64 data[] __counted_by(.u64s - BKEY_U64s); }; And bch_val could be dropped... Then the memcpy becomes: k->k.u64s++; k->k.data[bkey_val_u64s(&k->k)] = (u64)ptr; It just seems like there is a lot of work happening that could really just type casting or unions...

You're adding a field that's specific to bch_extent (and not even correct for that) to bkey_i, the generic key; there are many other different types of values. > Alternatively, perhaps struct bkey could be the one to grow this flexible > array, and then it could eventually be tracked with __counted_by (but > not today since it expects to count the array element count, not a whole > struct size): > > struct bkey { > /* Size of combined key and value, in u64s */ > __u8 u64s; > ... > __u64 data[] __counted_by(.u64s - BKEY_U64s); > }; > > And bch_val could be dropped... bch_val can't be dropped. bkey_i is different from bkey; bkey_i is a bkey with an inline value, we also have bkey_s and bkey_s_c for a bkey with a split value (and const variation); bch_val is in bkey_i and not bkey because container_of to get to the value is correct for bkey_i, but not bkey. > Then the memcpy becomes: > > k->k.u64s++; > k->k.data[bkey_val_u64s(&k->k)] = (u64)ptr; > > It just seems like there is a lot of work happening that could really > just type casting or unions... Honestly, I think we really just need an escape hatch. Casting to a void pointer clearly isn't it - and this isn't the only issue I'm still seeing with all the recent FORTIFY_SOURCE stuff, and honestly it's been making me tear my hair out. I'm not leaping at the chance to reorganize my fundamental data structures for this. Can we get such an escape hatch? ^ permalink raw reply [flat|nested] 5+ messages in thread
