James Tucker 146f51ce76 net/packet: fix filtering of short IPv4 fragments ... The fragment offset is an 8 byte offset rather than a byte offset, so the short packet limit is now in fragment block size in order to compare with the offset value. The packet flags are in the first 3 bits of the flags/frags byte, and so after conversion to a uint16 little endian value they are at the start, not the end of the value - the mask for extracting "more fragments" is adjusted to match this byte. Extremely short fragments less than 80 bytes are dropped, but fragments over 80 bytes are now accepted. Fixes #5727 Signed-off-by: James Tucker <james@tailscale.com>		2022-09-23 10:43:28 -07:00
