Hello, I'm looking at some Clang Static Analyzer reports in the kernel, and a lot of them point back to a null pointer dereference in __pcpu_type (sys/amd64/include/pcpu.h:102) which is defined as:
102 /* 103 * Evaluates to the type of the per-cpu variable name. 104 */ 105 #define __pcpu_type(name) \ 106 __typeof(((struct pcpu *)0)->name) Which indeed looks like a NULL pointer dereference. Looking at the latest commit message there, I'm sure the code is correct, but I'm unsure why the null pointer is OK. I'd appreciate an explanation :-) Thanks, Erik _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
