* [netdevice] Add vlan_tag() to get the VLAN tag of a network deviceStefan Hajnoczi2013-03-011-0/+1
| | | | | | | | | | | | The iBFT has a VLAN field that should be filled in. Add the vlan_tag() function to extract the VLAN tag of a network device. Since VLAN support is optional, define a weak function that returns 0 when iPXE is built without VLAN support.

* [serial] Don't enable serial console without serial supportShao Miller2012-10-051-0/+1
| | | | | | | | | | | serial_console_init() would enable serial console support without knowing if the serial driver succeeded or not. As a result, the serial console would interfere with a normal keyboard on a system lacking serial support.

* [tls] Split received records over multiple I/O buffersMichael Brown2012-09-271-4/+26
| | | | | | | | | | | | | | | TLS servers are not obliged to implement the RFC3546 maximum fragment length extension, and many common servers (including OpenSSL, as used in Apache's mod_ssl) do not do so. iPXE may therefore have to cope with TLS records of up to 16kB. Allocations for 16kB have a non-negligible chance of failing, causing the TLS connection to abort. Fix by maintaining the received record as a linked list of I/O buffers, rather than a single contiguous buffer. To reduce memory pressure, we also decrypt in situ, and deliver the decrypted data via xfer_deliver_iob() rather than xfer_deliver_raw(). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [settings] Use a generic setting's own type as its default typeMichael Brown2012-09-101-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When fetching a named setting using a name that does not explicitly specify a type, default to using the type stored when the setting was created, rather than always defaulting to "string". This allows the behaviour of user-defined settings to match the behaviour of predefined settings (which have a sensible default type). For example: set server:ipv4 192.168.0.1 echo ${server} will now print "192.168.0.1", rather than trying to print out the raw IPv4 address bytes as a string. The downside of this change is that existing tricks for printing special characters within scripts may require (backwards-compatible) modification. For example, the "clear screen" sequence: set esc:hex 1b set cls ${esc}[2J echo ${cls} will now have to become set esc:hex 1b set cls ${esc:string}[2J # Must now explicitly specify ":string" echo ${cls} Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [ipoib] Expose Ethernet-compatible eIPoIB link-layer addresses and headersMichael Brown2012-08-313-19/+34
| | | | | | | | | | | | | Almost all clients of the raw-packet interfaces (UNDI and SNP) can handle only Ethernet link layers. Expose an Ethernet-compatible link layer to local clients, while remaining compatible with IPoIB on the wire. This requires manipulation of ARP (but not DHCP) packets within the IPoIB driver. This is ugly, but it's the only viable way to allow IPoIB devices to be driven via the raw-packet interfaces. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [tcp] Increase maximum window size to 256kBMichael Brown2012-07-091-22/+24

* [arp] Try to avoid discarding ARP cache entriesMichael Brown2012-07-091-1/+12
| | | | | | | | | Discarding the active ARP cache entry in the middle of a download will substantially disrupt the TCP stream.

* [iobuf] Relax alignment requirement for small I/O buffersMichael Brown2012-06-291-11/+0Star
| | | | | | | | | | | | | iPXE currently aligns all I/O buffers on a 2kB boundary. This is overkill for transmitted packets, which are typically much smaller than 2kB. Align I/O buffers on their own size. This reduces the alignment requirement for small buffers, while preserving the guarantee that I/O buffers will never cross boundaries that might cause problems for some DMA engines.

* [tls] Request a maximum fragment length of 2048 bytesMichael Brown2012-06-291-1/+8
| | | | | | | | | | | The default maximum plaintext fragment length for TLS is 16kB, which is a substantial amount of memory for iPXE to have to allocate for a temporary decryption buffer. Reduce the memory footprint of TLS connections by requesting a maximum fragment length of 2kB. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [tcp] Add support for TCP window scalingMichael Brown2012-06-291-1/+29
| | | | | | | | The maximum unscaled TCP window (64kB) implies a maximum bandwidth of around 300kB/s on a WAN link with an RTT of 200ms. Add support for the TCP window scaling option to remove this upper limit. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Allow an error margin on X.509 certificate validity periodsMichael Brown2012-06-202-8/+8
| | | | | | | | | | | | | iPXE has no concept of the local time zone, mainly because there is no viable way to obtain time zone information in the absence of local state. This causes potential problems with newly-issued certificates and certificates that are about to expire. Avoid such problems by allowing an error margin of around 12 hours on certificate validity periods, similar to the error margin already allowed for OCSP response timestamps.
