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.
