Change in coreboot[master]: src: Remove variable length arrays
by Jacob Garber (Code Review) 03 Jul '19

03 Jul '19

Hello Aaron Durbin, Julius Werner, Angel Pons, David Hendricks, build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/33821 to look at the new patch set (#9). Change subject: src: Remove variable length arrays ...................................................................... src: Remove variable length arrays Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].
