Prior to commit 35e9a0a8ce4b ("target/arm/arm-semi: Make semihosting code hand out its own file descriptors"), the guest fd matched to the host fd. It returned a nonzero handle on success since the fd 0 is already used for stdin. Now that the guest fd is the index of guestfd_array, it starts from 0. I noticed this issue particularly because Trusted Firmware-A built with PLAT=qemu is no longer working. Its io_semihosting driver only handles a positive return value as a valid filehandle. Basically, there are two ways to fix this: - Use (guestfd - 1) as the index of guestfs_arrary. We need to insert increment/decrement to convert the guestfd and the array index back and forth. - Keep using guestfd as the index of guestfs_array. The first entry of guestfs_array is left unused. I thought the latter is simpler. We end up with wasting a small piece of memory for the unused first entry of guestfd_array, but this is probably not a big deal.
