Eigler Date: Mon Nov 7 14:20:26 2011 -0500 PR13386: avoid _stp_printf() crash for null context / %M or %m If _stp_printf() were invoked with %M or %m directive that resulted in an error, it likes to write into the current stap probe handler context about it. However, _stp_printf is sometimes used outside probe handler context, in which case no context is actually available, such as during module_exit(). So we tolerate a null context pointer (it just having been deallocated). Note that there don't exist any current %M/%m outputs in the runtime that could trigger this NULL-deref, so this is only a prophylactic measure. * runtime/vsprintf.c (_stp_vsprint_memory): Tolerate null context. commit c114ce7ffcb39e37f6468be80ffa3fa1f18bcf0e Author: Frank Ch. Eigler Date: Mon Nov 7 14:19:05 2011 -0500 PR13386: disable preemption around printing-happy parts of *module_exit(). * translate.cxx (c_unparser::emit_module_exit): Since we use stp_printf (that internally is preempt-sensitive), we need to disable preemption (or at least cpu switching) during this stage. commit fcf41197e6e1500b60aba1c838e2d9fe53e2c98a Author: Frank Ch.
