0.6.0

Changed

• PR#16 changed RxRing and TxRing to use the new slab::Slab trait.
• PR#16 moved HeapSlab to the new slab module, and made it implement slab::Slab, changing it so that items are always pushed to the front and popped from the back, unlike the previous implementation which allowed both.
• PR#17 changed CsumOffload::Request(xdp::libc::xdp::xsk_tx_request) -> CsumOffload::Request { start: u16, offset: u16 }

Added

• PR#16 added a new slab::StackSlab<N> fixed size ring buffer that implements slab::Slab.
• PR#17 added various doc examples.

Fixed

• PR#16 fixed some undefined behavior in the netlink code used to query NIC capabilities.
• PR#16 fixed a bug where TX metadata would not be added and would return an error if the packet headroom was not large enough for the metadata, this is irrelevant.
• PR#17 fixed the exceptional case where a UDP checksum is calculated to be 0, in which case it is set to 0xffff instead.

0.5.0

Changed

• PR#15 renamed UdpPacket -> UdpHeaders, and changed the contents to be the actual headers that can be de/serialized from/to the packet buffer.
• PR#15 moved to edition 2024.

Added

• PR#15 added various utility methods to the types in net_types.
• PR#15 added Debug impls for various types gated behind the __debug feature since they are mainly only for internal testing.
• PR#15 added miri checking to CI, resolving #13.

Fixed

• PR#15 fixed an issue where UDP checksum calculation could be incorrect depending on the input data.

Removed

• PR#15 removed the Packet::item_at_offset and Packet::item_at_offset_mut methods as they had undefined behavior, replaced by the read and write methods.
• PR#15 removed Packet::slice_at_offset and Packet::slice_at_offset_mut in favor of just letting the user use Deref/DerefMut.

0.4.0

Changed

• PR#11 fixed documentation, but also moved some types and constants around in the libc module.
• PR#14 changed Packet::array_at_offset to take a &mut [u8; N] rather than return it.

Fixed

• PR#14 fixed a bug where inserting past the end of the tail would not return an Err.

Added

• PR#14 ungated the Debug impls for XdpFeatures, XdpRxMetadata, XdpTxMetadata, XdpZeroCopy, and NetdevCapabilities.

0.3.0

Changed

• PR#7 removed libc in favor of inline bindings.
• PR#9 removed neli in favor of a simpler inline implementation, resolving #1.
• PR#10 removed memmap2 in favor of a simpler inline implementation, resolving #8.

0.2.0

Fixed

• PR#4 fixed support for TX checksum offload.

Added

• PR#6 fleshed out documentation
• PR#6 added crate::nic::InterfaceIter to enumerate available interfaces

Changed

• PR#6 crate::nic::NicIndex::queue_count now returns a crate::nic::Queues struct rather than a tuple

0.1.0

Added

• PR#3 added the first pass implementation of the crate with a (mostly) working implementation focused on UDP packets. See the PR for a more detailed description of what is and is not supported.
