* net: vmxnet: use g_new for pkt initialisationLi Qiang2016-08-181-3/+2
| | | | | | | | | | | | When network transport abstraction layer initialises pkt, the maximum fragmentation count is not checked. This could lead to an integer overflow causing a NULL pointer dereference. Replace g_malloc() with g_new() to catch the multiplication overflow.

* net: check fragment length during fragmentationPrasad J Pandit2016-08-091-1/+1
| | | | | | | | | | | | | | Network transport abstraction layer supports packet fragmentation. While fragmenting a packet, it checks for more fragments from packet length and current fragment length. It is susceptible to an infinite loop, if the current fragment length is zero. Add check to avoid it.

* net_pkt: Extend packet abstraction as required by e1000e functionalityDmitry Fleytman2016-06-021-77/+127
| | | | | | | | | | | | | | | | | | This patch extends the TX/RX packet abstractions with features that will be used by the e1000e device implementation. Changes are: 1. Support iovec lists for RX buffers 2. Deeper RX packets parsing 3. Loopback option for TX packets 4. Extended VLAN headers handling 5.

* net_pkt: Name vmxnet3 packet abstractions more genericDmitry Fleytman2016-06-021-0/+581
This patch drops "vmx" prefix from packet abstractions names to emphasize the fact they are generic and not tied to any specific network device. These abstractions will be reused by e1000e emulation implementation introduced by following patches so their names need generalization.
