Bug #: 13793
Summary: IPv6 nfs_proc.stp tapset changes needed
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tapsets
AssignedTo: systemtap@sourceware.org
ReportedBy: dsmith@redhat.com
Depends on: 13646
Classification: Unclassified
The nfs_proc.stp tapset is full of probes that return 'server_ip', a binary IP
address of the server. A typical line to generate that value looks like this:
server_ip = __i2n_ip_proto($dir,0)
That works fine for IPv4. That binary value can be used in comparisons, as an
array index, etc. However, the above doesn't work for IPv6. That function (if
it supported IPv6) would return the address of a structure that holds the IPv6
address.
Those probes should be changed to return a string representation of the IP
address, which can be compared properly for both IPv4 and IPv6.
(Bug #13646 provided the base tapset IPv6 support.)
