* [smbios] Expose board serial number as ${board-serial}Dale Hamel2014-06-121-0/+17
| | | | | | | | With blade servers, the chassis serial number (exposed via ${serial}) may not be unique. Expose ${board-serial} as a named setting to provide easy access to a more meaningful serial number. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [iscsi] Include IP address origin in iBFTMichael Brown2014-06-121-0/+8
| | | | | | | | | | | The iBFT includes an "origin" field to indicate the source of the IP address. We use the heuristic of assuming that the source should be "manual" if the IP address originates directly from the network device settings block, and "DHCP" otherwise. This is an imperfect guess, but is likely to be correct in most common situations. Originally-implemented-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Generalise X.509 cache to a full certificate storeMichael Brown2014-03-286-65/+63Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expand the concept of the X.509 cache to provide the functionality of a certificate store. Certificates in the store will be automatically used to complete certificate chains where applicable. The certificate store may be prepopulated at build time using the CERT=... build command line option. For example: make bin/ipxe.usb CERT=mycert1.crt,mycert2.crt Certificates within the certificate store are not implicitly trusted; the trust list is specified using TRUST=... as before. For example: make bin/ipxe.usb CERT=root.crt TRUST=root.crt This can be used to embed the full trusted root certificate within the iPXE binary, which is potentially useful in an HTTPS-only environment in which there is no HTTP server from which to automatically download cross-signed certificates or other certificate chain fragments. This usage of CERT= extends the existing use of CERT= to specify the client certificate. The client certificate is now identified automatically by checking for a match against the private key. For example: make bin/ipxe.usb CERT=root.crt,client.crt TRUST=root.crt KEY=client.key Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Remove dynamically-allocated storage for certificate nameMichael Brown2014-03-251-1/+4
| | | | | | | | | | | | | | iPXE currently allocates a copy the certificate's common name as a string. This string is used by the TLS and CMS code to check certificate names against an expected name, and also appears in debugging messages. Provide a function x509_check_name() to centralise certificate name checking (in preparation for adding subjectAlternativeName support), and a function x509_name() to provide a name to be used in debugging messages, and remove the dynamically allocated string.

* [efi] Disable SNP devices when running iPXE as the applicationMichael Brown2014-03-141-0/+4
| | | | | | | | | | | | | Some UEFI builds will set up a timer to continuously poll any SNP devices. This can drain packets from the network device's receive queue before iPXE gets a chance to process them. Use netdev_rx_[un]freeze() to explicitly indicate when we expect our network devices to be driven via the external SNP API (as we do with the UNDI API on the standard BIOS build), and disable the SNP API except when receive queue processing is frozen.

* [tcp] Calculate correct MSS from peer addressMichael Brown2014-03-041-10/+0Star
| | | | | | | | | | | | | | | | | | | iPXE currently advertises a fixed MSS of 1460, which is correct only for IPv4 over Ethernet. For IPv6 over Ethernet, the value should be 1440 (allowing for the larger IPv6 header). For non-Ethernet link layers, the value should reflect the MTU of the underlying network device. Use tcpip_mtu() to calculate the transport-layer MTU associated with the peer address, and calculate the MSS to allow for an optionless TCP header as per RFC 6691. As a side benefit, we can now fail a connection immediately with a meaningful error message if we have no route to the destination address. Reported-by: Anton D.

* [tcpip] Provide tcpip_mtu() to determine the maximum transmission unitMichael Brown2014-03-041-0/+3

* [uri] Refactor URI parsing and formattingMichael Brown2014-02-271-37/+41
| | | | | | | | | | | | | | | | | | | | | | | | Add support for parsing of URIs containing literal IPv6 addresses (e.g. "http://[fe80::69ff:fe50:5845%25net0]/boot.ipxe"). Duplicate URIs by directly copying the relevant fields, rather than by formatting and reparsing a URI string. This relaxes the requirements on the URI formatting code and allows it to focus on generating human-readable URIs (e.g. by not escaping ':' characters within literal IPv6 addresses). As a side-effect, this allows relative URIs containing parameter lists (e.g. "../boot.php##params") to function as expected. Add validity check for FTP paths to ensure that only printable characters are accepted (since FTP is a human-readable line-based protocol with no support for character escaping). Construct TFTP next-server+filename URIs directly, rather than parsing a constructed "tftp://..." string, Add self-tests for URI functions. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [dns] Support DNS search listsMichael Brown2014-02-053-61/+121
| | | | | | | | | | | Update the DNS resolver to support DNS search lists (as provided by DHCP option 119, DHCPv6 option 24, or NDP option 31). Add validation code to ensure that parsing of DNS packets does not overrun the input, get stuck in infinite loops, or (worse) write beyond the end of allocated buffers.

* [cmdline] Rename "console" command's --bpp option to --depthMichael Brown2014-01-221-1/+1
| | | | | | | | | | Rename the "--bpp" option to "--depth", to free up the single-letter option "-b" for "--bottom" in preparation for adding margin support. This does not break backwards compatibility with documented features, since the "console" command has not yet been documented. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [fbcon] Centre background picture on consoleMichael Brown2014-01-221-8/+0Star
| | | | | | | | | | | | | | | | | | | | | | | Centre the background picture on the console, to give a more consistent result when the aspect ratio does not match the requested width and height. Once drawn for the first time, nothing should ever overwrite the margins of the display. We can therefore eliminate the logic used to redraw only the margin areas, and use much simpler code to draw the complete initial background image. Simplify the redrawing logic further by making the background picture buffer equal in size to the frame buffer. In the common case of a background picture which is designed to fill the screen, this wastes no extra memory, and the combined code simplifications reduce the size of fbcon.o by approximately 15%. Redefine the concept of "margin" to match the intuitive definition (i.e. the size of the gap, rather than the position of the boundary line). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [console] Add concept of a "magic" colourMichael Brown2013-12-091-0/+11
| | | | | | | | The magic basic colour can be remapped at runtime from COLOR_NORMAL_BG (usually blue) to COLOR_DEFAULT (which will be transparent as a background colour on the framebuffer console). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Add centralised concept of colours and colour pairsMichael Brown2013-12-092-0/+75
| | | | | | | | | | | | | Add a centralised concept of colours and colour pairs (using the default colour pairs as configured via config/colour.h). A colour pair consists of a pair of colour indices. Add the ability to redefine both a colour pair and an individual colour index, with minimal overhead if this feature is not required (e.g. because the relevant shell commands are not present in the build). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Allow consoles to update the recorded console sizeMichael Brown2013-12-061-0/+20
| | | | | | | | | | | | | | | | | | | | Provide a mechanism for consoles to update the recorded console width and height, and use this width and height to provide the curses COLS and LINES variables. We choose not to use ANSI escape sequences to obtain the width and height, for two reasons: - iPXE's model is that all output is sent to all consoles; we could therefore end up with multiple consoles reporting conflicting widths and heights - when a serial console is in use, we probably don't want to resize the output shown on the BIOS console to match the size of the serial console, since it's likely that the serial console is in use only for debugging.
