2020-12-10Disable host reassembly for fragments.Bhasker Hariharan
fdbased endpoint was enabling fragment reassembly on the host AF_PACKET socket to ensure that fragments are delivered inorder to the right dispatcher. But this prevents fragments from being delivered to gvisor at all and makes testing of gvisor's fragment reassembly code impossible. The potential impact from this is minimal since IP Fragmentation is not really that prevelant and in cases where we do get fragments we may deliver the fragment out of order to the TCP layer as multiple network dispatchers may process the fragments and deliver a reassembled fragment after the next packet has been delivered to the TCP endpoint. While not desirable I believe the impact from this is minimal due to low prevalence of fragmentation. Also removed PktType and Hatype fields when binding the socket as these are not used when binding. Its just confusing to have them specified. See: https://man7.org/linux/man-pages/man7/packet.7.html "Fields used for binding are sll_family (should be AF_PACKET), sll_protocol, and sll_ifindex." Fixes #5055 PiperOrigin-RevId: 346919439

2020-12-10Use specified source address for IGMP/MLD packetsGhanan Gowripalan
This change also considers interfaces and network endpoints enabled up up to the point all work to disable them are complete. This was needed so that protocols can perform shutdown work while being disabled (e.g. sending a packet which requires the endpoint to be enabled to obtain a source address).

2020-12-09[netstack] Make tcpip.Error savable.Ayush Ranjan
Earlier we could not save tcpip.Error objects in structs because upon restore the constant's address changes in netstack's error translation map and translating the error would panic because the map is based on the address of the tcpip.Error instead of the error itself. Now I made that translations map use the error message as key instead of the address. Added relevant synchronization mechanisms to protect the structure and initialize it upon restore.

2020-12-09Refactor the Makefile to avoid recursive Make.Adin Scannell
Recursive make is difficult to follow and debug. Drop this by using internal functions, which, while difficult, are easier than trying to following recursive invokations.
