Bug ID: 27112
Summary: GL(dl_tls_generation) may overflow on 32bit targets
and abort during dlopen and dlclose
Product: glibc
Version: 2.32
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: nsz at gcc dot gnu.org
Target Milestone: ---
the generation count is incremented in dlopen and dlclose
and it is checked for overflow, but the overflow aborts the
process.
only 32bit targets can realistically run into such overflow
(where 4billion dlopen/dlclose calls can trigger it).
