             Bug #: 14005
           Summary: don't freak on overlong kernel module relocs
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sourceware.org
        ReportedBy: fche@redhat.com
    Classification: Unclassified


OK, so a user loads fglrx or some other c++ kernel module.  Now they have
relocation sections with long names, including such beauties as 

115
.gnu.linkonce.r._ZZN6AsicSII20ucode_class_pitcairnE24programApertureRegistersEjP14APERTURE_STATEE15UPPER_BOUND_GAP
116
.gnu.linkonce.t._ZN6AsicSII20ucode_class_pitcairnE23initializeApertureStateEP14APERTURE_STATEP18SURFACE_PROPERTIESm
136
.gnu.linkonce.t._ZNK25CMMHeap_FRAME_BUFFER_COREI18CMMHeap_ASIC_LOCALE20get_addr_restrictionER16MSF_SURF_ATTRIBSP21MEMHEAP_ADDR_RESTRICT
138
.gnu.linkonce.t._ZN18VMDomainManager_NI17CreateVmDomainsNII14VMDomainNI_PIO14VMDomainNI_PM417VMDomainNI_DRMDMAEEb22_VM_PROGRAMMING_METHOD
138
.gnu.linkonce.t._ZN18VMDomainManager_NI17CreateVmDomainsNII14VMDomainNI_PIO14VMDomainNI_PM417VMDomainSI_DRMDMAEEb22_VM_PROGRAMMING_METHOD

for a glorious maximum "section name" length of 138.

With bug #12612, we've once bumped up the symbol length limits, but not enough.
 Nothing is ever enough, when you have enough C++ templates!  So we need some
combination of relaxing limits more and/or keeping staprun from giving up so
pessimistically in case of an overlong reloc name.
