[Freeipmi-devel] RE: Old libfreeipmi bug fix

[Cress, Andrew R]

Al,

Ah, you were right about the sequence number thing.
I did have the resolution in the ipmiutil/ipmignu.c, and I retested it
with a long SEL session, to make sure.  So, that change is not needed.

Hey Andrew,

I remember the patch.  I wasn't quite sure why it didn't make it into
0.1.3.  Then I looked at the tag and ChangeLog dates.  The fix was
applied post 0.1.3 :-(

By the way, I believe you want "from = sizeof(struct sockaddr_in)" in
your patch if you were applying it locally.  Also didn't we fix the
sequence numbering problem in ipmiutil userspace??  I dug up and e-mail
showing I gave you this:

  rv = ipmi_lan_cmd(sockfd, hostaddr, hostaddr_len,
                    auth_type, session_seqnum, session_id,
                    authcode, authcode_len,
                    netfn, IPMI_BMC_IPMB_LUN_BMC, (rq_seq %
 (IPMI_LAN_SEQ_NUM_MAX + 1)),
                    cmd_rq, tmpl_rq, cmd_rs, tmpl_rs);
