Summary: *_dri.so unloaded prematurely by nested open/close
display calls
Product: Mesa
Version: CVS
Platform: All
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: GLX
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
When dri_glx.c:OpenDisplay is called for a driver that is already loaded the
function returns a pointer to the library without incrementing its reference
count. This can come from nested calls in one thread or from multiple threads
within a process. Unfortunately the first close works its way down to the
dlclose in driDestroyDisplay and the library is unloaded which invalidates
other references to its contents.
The attached patch amends the function to bump the reference count for driver
libraries before returning a pointer to them.
