Red Hat Bugzilla – Bug 259681
need to enhance getaddrinfo to support optimistic addresses
Last modified: 2008-05-21 12:52:18 EDT
Description of problem:
RFC 4429 requires that addresses flagged as optimistic be treated as depricated
addresses. Since getaddrinfo attempts to organize addresses according to the
priority laid out in RFC 3484, and IFA_F_OPTIMISTIC is a separate kernel flag,
we need to update getaddrinfo to recognize this flag and handle it accordingly.
Created attachment 175961 [details]
patch to add optimistic support to getaddrinfo
The patch is upstream.
Change is so far in rawhide glibc-2.6.90-14.
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
Jakub, can you tell me if this is inglibc for 5.2 yet? Thanks!
Need this for IPv6. QE Ack.
We need this fix in rhel 5.2 to meet IPV6DoD testing requirements. Jakub, can
you please answer the question above?
yes, to both question, in RHEL5.2
BTW, the linux-2.6-net-ipv6-backport-optimistic-dad.patch patch changes userland
API, which is very undesirable for RHEL5. linux/rtnetlink.h just should for RHEL5
the newly added linux/if_addr.h header, or instead of creating a new header the
new stuff should be just added directly into linux/rtnetlink.h.
