a88c3163 | 1 | The following issues exist with the EFI Socket Library:\r |
2 | \r | |
3 | * Don't run socket applications or the socket driver for a long time - The IPv4Config\r | |
4 | and DHCP protocols are not properly running the renew and lease expiration timers.\r | |
5 | When the DHCP lease expires it is possible for a duplicate IP address to exist on\r | |
6 | the network. HSD 206136\r | |
7 | \r | |
8 | * Network adapters must be initialized prior to running the socket application - Static\r | |
9 | and dynamic IP address need to be properly assigned to the network adapters on the\r | |
10 | system. Note that sockets does not assign the IP addresses since it does not\r | |
11 | understand how the system is connected to the network!\r | |
12 | \r | |
13 | * The default device must contain the Efi\etc directory populated with files containing\r | |
14 | the proper network configuration - A template set of files is in StdLib\Efi\etc. Note\r | |
15 | that the resolv.conf file contains the set of DNS servers.\r | |
16 | \r | |
17 | * Since DHCP is not running when the sockets application is running, the last negotiated\r | |
18 | packet is no longer available. As a result, any of the options that DHCP did negotiate\r | |
19 | are no longer available for sockets such as the list of DNS servers.\r | |
20 | \r | |
21 | * DHCP does not request the domain name and domain name server (DNS) addresses. This\r | |
22 | requires that sockets use configuration files in Efi\etc!\r | |
23 | \r | |
24 | * TCPv4 transfer rate is slow (< 10 Mbits/sec) - This is an unidentified issue.\r | |
25 | \r | |
58081f2c | 26 | * Tcp4Dxe transmits more urgent data than is sent through sockets when normal data is\r |
27 | queued for transmission before the urgent data. HSD 206365\r | |
28 | \r | |
a88c3163 | 29 | * Raw socket applications are not able to pass the IP header as part of their\r |
30 | payload by using the IP option IP_HDRINCL. This is because the UEFI IPv4 driver\r | |
31 | (Ip4Dxe) does not support RawData. HSD 206136\r | |
32 | \r | |
33 | * Only version 4 of the UEFI network stack is supported\r | |
