Suppress file open failures for some netboot cases

2025-02-18T15:21:19+00:00

Reading files during a netboot comes with the caveat that fetching files from a network does not support anything like listing a directory. In the past this has meant that we do not try to open optional files during a netboot. However at least the revocation.efi file is now tested during a netboot, which will print an error when it is not found. Since that error is spurious we should allow for those errors to be suppressed. This is also desirable since we will likely go looking for additional files in the near future.

netboot: Convert TFTP error codes to EFI status codes

2025-01-15T21:03:55+00:00

This allows the caller to make a more informed decision about how to handle the error. The error code is available in the TftpError field of the Mode interface. In particular, by mapping the TFTP errors to EFI_INVALID_PARAMTER and EFI_NOT_FOUND, shim will try to fetch the default second stage image like it does when loading images from disk. Unfortunately, some firmware doesn't fill in the error fields, so a generic EFI_TFTP_ERROR to EFI_NOT_FOUND conversion is included. Signed-off-by: Dan Nicholson

netboot read_image() should not hardcode DEFAULT_LOADER

2024-01-22T19:17:20+00:00

The netboot path up until now hardcodes DEFAULT_LOADER as the only possible filename to load. This is pretty limiting and needs to be fixed. Signed-off-by: Jan Setje-Eilers

Work around malformed path delimiters in file paths from DHCP

2023-06-21T17:44:20+00:00

shim uses path delimiters to determine the file path for the second stage. Currently only / (slash) is detected, but some DHCP implementations supply \ (backslash) as the path specifier. This patch changes it to accept either delimiter. Fixes issue #524. Signed-off-by: Alberto Perez

cleanup: always use BS and RT, not gBS and gRT

This just makes one less thing we have to make sure is the same between the test harnesses and the runtime code. Signed-off-by: Peter Jones

Consolidate most of our standard lib functions to lib

Restructure our includes.

2021-03-10T20:54:20+00:00

This re-structures our includes so we can be sure everything is always including all the system headers in a uniform, predictable way. Temporarily it also adds a bunch of junk at all the places we use variadic functions to specifically pick either the MS (cdecl) or ELF ABIs. I'm not 100% sure that's all correct (see later patch) but it's enough to allow this to build. Signed-off-by: Peter Jones

Fix up a bunch of our license statements and add SPDX most places

2021-02-16T08:12:48+00:00

The license statements in our source files were getting to be a giant mess, and mostly they all just say the same thing. I've switched most of it to SPDX labels, but left copyright statements in place (where they were not obviously incorrect copy-paste jobs that I did...). If there's some change here you don't think is valid, let me know and we can fix it up together. Signed-off-by: Peter Jones
