I’ve just pulled the latest iPXE code (after more than a couple of
years) and started getting a http://ipxe.org/3c00e183 error when trying
to boot over HTTPS.
Investigating a bit revealed that in my iPXE binary the asn1_algorithms
link table entries are offset by 48 bytes while the size of the asn1
_algorithm struct is 40 bytes so the ‘for_each_table_entry ( algorithm,
ASN1_ALGORITHMS )’ doesn’t cycle over the asn1_algorithms in the link
table correctly.
I tried adding a dummy field of 8 bytes to the asn1_algortihm struct
which resolved the above error but then I started receiving
http://ipxe.org/420c6095 so I suspect I’m not building iPXE correctly.
Could you please let me know if somebody else had observed a similar
problem lately and what may be causing it (I suspect this may be related
to some alignment/padding misconfiguration but don’t know how this is
controlled).
Interesting. Which compiler are you using?
We've had previous issues with icc adding unexpected packing, but I have
not seen this problem with gcc.
Thanks,
Michael
