* [console] Fix unreachable characters in "il" keymapMichael Brown2022-02-151-0/+1

* [console] Treat dead keys as producing their ASCII equivalentsMichael Brown2022-02-1514-5/+41
| | | | | | | | Treat dead keys in target keymaps as producing the closest equivalent ASCII character, since many of these characters are otherwise unrepresented on the keyboard. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Support AltGr to access ASCII characters via remappingMichael Brown2022-02-1530-0/+266
| | | | | | | | | | | | | Several keyboard layouts define ASCII characters as accessible only via the AltGr modifier. Add support for this modifier to ensure that all ASCII characters are accessible. Experiments suggest that the BIOS console is likely to fail to generate ASCII characters when the AltGr key is pressed. Work around this limitation by accepting LShift+RShift (which will definitely produce an ASCII character) as a synonym for AltGr. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Allow for named keyboard mappingsMichael Brown2022-02-1530-60/+270
| | | | | | | | Separate the concept of a keyboard mapping from a list of remapped keys, to allow for the possibility of supporting multiple keyboard mappings at runtime. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Handle remapping of scancode 86Michael Brown2022-02-1022-0/+44
| | | | | | | | | | | | | | | | | The key with scancode 86 appears in the position between left shift and Z on a US keyboard, where it typically fails to exist entirely. Most US keyboard maps define this nonexistent key as generating "\|", with the notable exception of "loadkeys" which instead reports it as generating "<>". Both of these mapping choices duplicate keys that exist elsewhere in the map, which causes problems for our ASCII-based remapping mechanism. Work around these quirks by treating the key as generating "\|" with the high bit set, and making it subject to remapping. Where the BIOS generates "\|" as expected, this allows us to remap to the correct ASCII value. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [console] Update genkeymap to work with current databasesMichael Brown2022-02-1022-246/+87

* [linux] Use host glibc system call wrappersMichael Brown2021-02-281-17/+3
| | | | | | | | | | | | | | | | | | | | | | When building as a Linux userspace application, iPXE currently implements its own system calls to the host kernel rather than relying on the host's C library. The output binary is statically linked and has no external dependencies. This matches the general philosophy of other platforms on which iPXE runs, since there are no external libraries available on either BIOS or UEFI bare metal. However, it would be useful for the Linux userspace application to be able to link against host libraries such as libslirp. Modify the build process to perform a two-stage link: first picking out the requested objects in the usual way from blib.a but with relocations left present, then linking again with a helper object to create a standard hosted application. The helper object provides the standard main() entry point and wrappers for the Linux system calls required by the iPXE Linux drivers and interface code. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [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.

| | | | | | | | | | | | Some of the C library string functions have an unknown provenance. Reimplement all such functions to avoid potential licensing uncertainty.

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