Struct FailureDumpFdArray 

#[non_exhaustive]
pub struct FailureDumpFdArray {
    pub populated: u32,
    pub scanned: u32,
    pub indices: Vec<u32>,
    pub truncated: bool,
    pub indices_truncated: bool,
    pub unreadable: u32,
}

Per-FD-array snapshot of populated indices.

FD-array families store void * slots in bpf_array.ptrs; each slot is either NULL (empty) or a kernel pointer (struct bpf_prog *, struct file *, etc.). The dump path reads up to MAX_FD_ARRAY_SLOTS slots, counts non-zero, and lists the populated indices.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

populated: u32

Number of populated (non-zero) slots seen.

scanned: u32

Total slots scanned. Capped at MAX_FD_ARRAY_SLOTS.

indices: Vec<u32>

Indices of populated slots. Truncated to MAX_FD_ARRAY_INDICES entries.

truncated: bool

True when iteration capped at MAX_FD_ARRAY_SLOTS and scanned < max_entries.

indices_truncated: bool

True when populated > indices.len() because MAX_FD_ARRAY_INDICES capped the index list.

unreadable: u32

Count of scanned slots whose KVA could not be translated to a guest physical address (an unmapped page in the ptrs flex array). These slots are neither confirmed empty nor counted as populated, so populated is a lower bound when this is non-zero. 0 when every scanned slot was readable.
