* [block] Allow use of a non-default EFI SAN boot filenameMichael Brown2017-04-121-3/+8
| | | | | | | | | | | | | | | | | | | | | | | Some older operating systems (e.g. RHEL6) use a non-default filename on the root disk and rely on setting an EFI variable to point to the bootloader. This does not work when performing a SAN boot on a machine where the EFI variable is not present. Fix by allowing a non-default filename to be specified via the "sanboot --filename" option or the "san-filename" setting. For example: sanboot --filename \efi\redhat\grub.efi \ iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6 or option ipxe.san-filename code 188 = string; option ipxe.san-filename "\\efi\\redhat\\grub.efi"; option root-path "iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6"; Originally-implemented-by: Vishvananda Ishaya Abrams <vish.ishaya@oracle.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [block] Add basic multipath supportMichael Brown2017-03-261-15/+15
| | | | | | | | | | | Add basic support for multipath block devices. The "sanboot" and "sanhook" commands now accept a list of SAN URIs. We open all URIs concurrently. The first connection to become available for issuing block device commands is marked as the active path and used for all subsequent commands; all other connections are then closed. Whenever the active path fails, we reopen all URIs and repeat the process. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [time] Allow timer to be selected at runtimeMichael Brown2017-01-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | Allow the active timer (providing udelay() and currticks()) to be selected at runtime based on probing during the INIT_EARLY stage of initialisation. TICKS_PER_SEC is now a fixed compile-time constant for all builds, and is independent of the underlying clock tick rate. We choose the value 1024 to allow multiplications and divisions on seconds to be converted to bit shifts. TICKS_PER_MS is defined as 1, allowing multiplications and divisions on milliseconds to be omitted entirely. The 2% inaccuracy in this definition is negligible when using the standard BIOS timer (running at around 18.2Hz). TIMER_RDTSC now checks for a constant TSC before claiming to be a usable timer. (This timer can be tested in KVM via the command-line option "-cpu host,+invtsc".) Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [build] Fix the REQUIRE_SYMBOL mechanismMichael Brown2015-03-051-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | At some point in the past few years, binutils became more aggressive at removing unused symbols. To function as a symbol requirement, a relocation record must now be in a section marked with @progbits and must not be in a section which gets discarded during the link (either via --gc-sections or via /DISCARD/). Update REQUIRE_SYMBOL() to generate relocation records meeting these criteria. To minimise the impact upon the final binary size, we use existing symbols (specified via the REQUIRING_SYMBOL() macro) as the relocation targets where possible. We use R_386_NONE or R_X86_64_NONE relocation types to prevent any actual unwanted relocation taking place. Where no suitable symbol exists for REQUIRING_SYMBOL() (such as in config.c), the macro PROVIDE_REQUIRING_SYMBOL() can be used to generate a one-byte-long symbol to act as the relocation target. If there are versions of binutils for which this approach fails, then the fallback will probably involve killing off REQUEST_SYMBOL(), redefining REQUIRE_SYMBOL() to use the current definition of REQUEST_SYMBOL(), and postprocessing the linked ELF file with something along the lines of "nm -u | wc -l" to check that there are no undefined symbols remaining.

* [libc] Rewrite string functionsMichael Brown2015-02-171-1/+1
| | | | | | | | | | | | Some of the C library string functions have an unknown provenance. Reimplement all such functions to avoid potential licensing uncertainty. Remove the inline-assembler versions of strlen(), memswap(), and strncmp(); these save a minimal amount of space (around 40 bytes in total) and are not performance-critical.

Note that this only allows for customisation of the user interface. Where the "iPXE" string serves a technical purpose (such as in the HTTP User-Agent), the string cannot be customised.

| | | | | | | | | | | | | | | | | | | | | | | | | Add the "-c <count>" option to the "ping" command, allowing for automatic termination after a specified number of packets. When a number of packets is specified: - if a serious error (i.e. length mismatch or content mismatch) occurs, then the ping will be immediately terminated with the relevant status code; - if at least one response is received successfully, and all errors are non-serious (i.e. timeouts or out-of-sequence responses), then the ping will be terminated after the final response (or timeout) with a success status; - if no responses are received successfully, then the ping will be terminated after the final timeout with ETIMEDOUT. If no number of packets is specified, then the ping will continue until manually interrupted.

* [image] Add "--timeout" parameter to image downloading commandsMichael Brown2014-03-104-9/+22
| | | | | | | | | | | | | | | | | | iPXE will detect timeout failures in several situations: network link-up, DHCP, TCP connection attempts, unacknowledged TCP data, etc. This does not cover all possible circumstances. For example, if a connection to a web server is successfully established and the web server acknowledges the HTTP request but never sends any data in response, then no timeout will be triggered. There is no timeout defined within the HTTP specifications, and the underlying TCP connection will not generate a timeout since it has no way to know that the HTTP layer is expecting to receive data from the server. Add a "--timeout" parameter to "imgfetch", "chain", etc. If no progress is made (i.e. no data is downloaded) within the timeout period, then the download will be aborted.

| | | | | | | | | | | | | | | | | | | | 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.
