Fix a segmentation fault that is caused by accessing an invalid "subedata" pointer on the last iteration of the init_eraseblock loop. Instead, short circuit the loop condition to check the sub block index first, and do not access the invalid pointer if it is the last sub block. Issue was encountered in: - OS: OpenBSD 7.5 amd64 - Compiler: clang 16.0.6 - Chip: Macronix MX25U6435E/F BUG=https://ticket.coreboot.org/issues/555 Change-Id: I61bf0d93aa9f0b2b420b146be16fcd5124f0dc5d Signed-off-by: Grant Pannell <grant@digitaldj.net> Reviewed-on: https://review.coreboot.org/c/flashrom/+/84234 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: DigitalDJ Reviewed-by: Anastasia Klimchuk <aklm@chromium.org>
flashrom README
===============
flashrom is a utility for detecting, reading, writing, verifying and erasing
flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images
in-system using a supported mainboard, but it also supports flashing of network
cards (NICs), SATA controller cards, and other external devices which can
program flash chips.
It supports a wide range of flash chips (most commonly found in SOIC8, DIP8,
SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various
protocols such as LPC, FWH, parallel flash, or SPI.
Do not use flashrom on laptops (yet)! The embedded controller (EC) present in
many laptops might interact badly with any attempts to communicate with the
flash chip and may brick your laptop.
Please make a backup of your flash chip before writing to it.
Please see the flashrom(8) manpage :doc:`classic_cli_manpage`.
Building / installing / packaging
---------------------------------
flashrom is built with **meson**. TLDR:
::
meson setup builddir
meson compile -C builddir
meson test -C builddir
meson install -C builddir
