I fixed up this patch so that it actually hooks into the build (as
below). (BTW, when sending patches in the future, please make them
apply with "-p1" -- your patches had paths like
/usr/src/linux-2.6.17-rc3/drivers/infiniband/ulp/iser-x/Kconfig
so I had to manually strip off the /usr/src/)
Anyway, with a config like
CONFIG_SCSI_ISCSI_ATTRS=y
# CONFIG_ISCSI_TCP is not set
CONFIG_INFINIBAND_ISER=y
My build fails with a bunch of errors like:
drivers/built-in.o: In function `iser_comp_error_worker':iser_verbs.c:(.text+0x7d7cd): undefined reference to `iscsi_conn_failure'
and so on. Is the correct fix for this to add
obj-$(CONFIG_INFINIBAND_ISER) += libiscsi.o
to drivers/scsi/Makefile?
Also, I get the following sparse warning:
drivers/infiniband/ulp/iser/iser_initiator.c:610:25: error: incompatible types for operation (&)
and the code there does look fishy:
itt = hdr->itt & ISCSI_ITT_MASK; /* mask out cid and age bits */
hdr->itt is __be32 but ISCSI_ITT_MASK is just (0xfff), so it seems
that there is something wrong, either with the iSCSI endianness
annotation or with the code itself.
Thanks,
Roland
