If we are using C++, we might as well use scope-based memory management
for these things, cleaner and less error prone. Also removed
unnecessary gotos.
The lines:
if (instance == PRIMARY_GPT)
hdr_offset = block_size;
else {
hdr_offset = lseek64(fd, 0, SEEK_END) - block_size;
}
if (hdr_offset < 0) {
fprintf(stderr, "%s: Failed to get gpt header offset\n",
__func__);
goto error;
}
are error checked. But previously hdr_offset could never be less than
zero because it was unsigned.
getting attributes work, setting them (e.g. with mark_boot_successful)
doesn't seem to work properly.
The IOCTL required to set the boot LUN doesn't work, some kernel driver
is missing for it.
This is a port of the Android bootctrl HAL and Qualcomms GPT based
implementation for musl/glibc based systems running mainline linux
Currently it doesn't work because the gpt hdr which is read doesn't
seem to have valid data.
