https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211924 --- Comment #6 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Jilles Tjoelker from comment #5) I believe we are compliant with the behavior for the partial page. We always zero-fill invalid parts of the partially-valid pages that are mapped into userspace. Was there a history behind the SIGBUS requirement ? I believe that the change for SIGBUS->SIGSEGV came with r151316, and I cannot remember such explicit language at that time. Anyway, I am certain that we do not want to change the signal definitions back, because there are programs that depend on it and which already did the switch to accommodate to the change. -- You are receiving this mail because: You are the assignee for the bug.
