2016-04-01NetworkPkg: Check received packet size before use it.Fu Siyuan
Arbitrary length of packet may be received from network, including the packets with zero payload data or malformed protocol header. So the code much check the actually received data size before using it. For example, in current edk2 network stack, an zero payload UDP packet may cause the platform ASSERT in NetbufFromExt() because of the zero fragment number. This patch update the IpIoLib and UdpIoLib to check and discard the zero payload data packet to avoid above assert. Some other network drivers are also updated to check the packet size to guarantee the minimum length of protocol header is received from upper layer driver.

2016-01-28NetworkPkg:Fix Network memory leak when calling GetModeData interfaceZhang Lubo
Multiple network protocols have a GetModeData() interface, which may allocate memory resource in the return mode data structure. It's callers responsibility to free these buffers.

2016-01-06NetworkPkg: DnsDxe: fix return type of DnsFillinQNameForQueryIp()Laszlo Ersek
Change the return type of DnsFillinQNameForQueryIp() from (UINT8*) to (CHAR*). This brings the function in sync with both its internal variables and all of its call sites, fixing the following gcc build breakage: > NetworkPkg/DnsDxe/DnsImpl.c: In function 'DnsFillinQNameForQueryIp': > NetworkPkg/DnsDxe/DnsImpl.c:1068:3: error: pointer targets in return > differ in signedness > [-Werror=pointer-sign] > return QueryName; > ^ The code was added in git commit fcae1a99 (SVN r19579).
