Date: Sat, 21 Jun 2014 09:30:30 -0400 From: Josh Boyer <jwboyer@...oraproject.org> To: Andy Lutomirski <luto@...capital.net>, "H. Peter Anvin" <hpa@...or.com> Cc: "Linux-Kernel@...r. Kernel. Org" <linux-kernel@...r.kernel.org> Subject: More 3.16 vdso fallout We've had a report[1] of d-bus getting a SEGV only on i686 machines with the 3.16 kernel. It's a bit light on specifics, but the relevant detail seems to be: "I'm pretty sure kernel is to blame here. The crash occurs when signal handler for RT signal 33 (used internaly by NPTL/pthreads) returns to address zero (not sure why). This only happens with 3.16 kernel, works fine with 3.15." and "Seems to be related to v3.16's arch/x86 VDSO changes. Works fine when booting with vdso=0." There isn't an actual backtrace for the SEGV in the bug, but we can ask for one. The kernels in question should be very recent, but lack the 5 patch series Andy recently sent as those aren't in Linus' tree yet. Not sure if those would impact anything or not. josh [1] https://bugzilla.redhat.com/show_bug.cgi?id=1110968 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
