efi-boot-shim.git/netboot.c, branch Release_3.0.0

Correctly reject bad tftp addresses earlier, rather than later.

2014-10-02T05:01:54+00:00

This check is for end == NULL but was meant to be *end == '\0'. Without this change, we'll pass a plausibly bad address (i.e. one with no ']' at the end) to Mtftp(... READ_FILE ...), which should fail correctly, but our error messaging will be inconsistent. Signed-off-by: Peter Jones

shim buffer overflow on ipv6 option parsing

Factor out x86-isms and add cross compile support

2014-08-12T14:54:05+00:00

This patch cleans up and refactors the Makefiles to better allow new architectures to be added: - remove unused Makefile definitions - import Makefile definitions from top level rather than redefining - move x86 specific CFLAGS to inside ifeq() blocks - remove x86 inline asm - allow $(FORMAT) to be overridden: this is necessary as there exists no EFI or PE/COFF aware objcopy for ARM Signed-off-by: Ard Biesheuvel

Fetch the netboot image from the same device

2014-06-25T13:53:23+00:00

The previous strategy is to locate the first available PXE_BASE_CODE protocol and to fetch the second stage image from it, and this may cause shim to fetch the wrong second stage image, i.e. grub.efi. Consider the machine with the following boot order: 1. PXE Boot 2. Hard Drive Assume that the EFI image, e.g. bootx64.efi, in the PXE server is broken, then "PXE Boot" will fail and fallback to "Hard Drive". While shim.efi in "Hard Drive" is loaded, it will find the PXE protocol is available and fetch grub.efi from the PXE server, not grub.efi in the disk. This commit checks the DeviceHandle from Loaded Image. If the device supports PXE, then shim fetches grub.efi with the PXE protocol. Otherwise, shim loads grub.efi from the disk.

Lengths that might be -1 can't be unsigned, Peter.

Fix path generation for Dhcpv4 bootloader.

2013-11-21T16:48:24+00:00

Right now we always look for e.g. "\grubx64.efi", which is completely wrong. This makes it look for the path shim was loaded from and modify that to end in a sanitized version of our default loader name. Resolves: rhbz#1032583 Signed-off-by: Peter Jones

Use CHAR8 not UINT8 for character work.

2013-10-02T14:46:26+00:00

This gets rid of a lot of type casting that we don't need, and helps reduce warnings when I switch a bunch of gnu-efi stuff to taking const arguments. Signed-off-by: Peter Jones

Since different distros name grub*.efi differently, make it compile-time.

2013-09-26T15:58:02+00:00

Basically, if you don't want grub.efi, you do: make 'DEFAULT_LOADER=\\\\grubx64.efi' Signed-off-by: Peter Jones
