Subject: bug fix patch
Date: Sun, 17 Apr 2005 19:37:02 -0700 [thread overview]
Message-ID: <b1fa2917050417193744e46d81@mail.gmail.com> (raw)
The following patch fixes 3 recent regressions and works around a 4th.
- when debugger trap entry was re-factored the new code neglected to
clear the trace bit in eflags on a trace trap, xc_ptrace now does that
in user-land before continuing
- a merge somewhere along the line removed a validation of the info
pointer in xc_domain_getfullinfo thus causing a seg fault when called
without info (xc_ptrace only wants the cpu context)
- the page not validated case in get_page_type needs to be last, in
the shadow mode code merge it was moved before the general type
checking case - when one tried to do an L2 pin on a page with a
self-reference xen would spin forever in cpu_relax. This patch returns
it to the last case.
- xen has started to use anonymous unions - this is not c99
compliant. As a workaround freebsd is no longer compiled with -std=c99
