[libvirt] [PATCH] util: Don't try to fchown files opened as non-root
by Jiri Denemark
When virFileOpenAs is called with VIR_FILE_OPEN_AS_UID flag and uid/gid
different from root/root while libvirtd is running as root, we fork a
new child, change its effective UID/GID to uid/gid and run
virFileOpenAsNoFork. It doesn't make any sense to fchown() the opened
file in this case since we already know that uid/gid can access the file
when open succeeds and one of the following situations may happen:
- the file is already owned by uid/gid and we skip fchown even before
this patch
- the file is owned by uid but not gid because it was created in a
directory with SETGID set, in which case it is desirable not to change
the group
- the file may be owned by a completely different user and/or group
because it was created on a root-squashed or even all-squashed NFS
filesystem, in which case fchown would most likely fail anyway

[libvirt] [PATCH] build: use gnulib pthread_sigmask
by Eric Blake
Gnulib finally learned how to do pthread_sigmask on mingw.
We still have to worry about optional signals, like SIGWINCH,
but overall, this makes for less conditional code.
* .gnulib: Update to latest, for pthread_sigmask.
* bootstrap.conf (gnulib_modules): Add pthread_sigmask.
* configure.ac (AC_CHECK_FUNCS): Drop redundant check.
* src/rpc/virnetclient.c (virNetClientSetTLSSession)
(virNetClientIOEventLoop): Make code unconditional.
* src/util/command.c (virFork): Likewise.
* tools/virsh.c (doMigrate, cmdMigrate): Likewise.

[libvirt] [PATCHv3] build: fix virBufferVasprintf on mingw
by Eric Blake
Gnulib documents that mingw vsnprintf is broken (it returns -1
on out-of-space, instead of the count of what would have been
printed); but while we were using the snprintf wrapper, we had
not yet been using the vsnprintf wrapper.
Meanwhile, mingw (but not mingw64) has a replacement snprintf
that fixes return values, but still lacks %1$s support; so in
that case, gnulib didn't replace snprintf, but libintl then
went ahead and installed a version that supported %1$s but not
return values. Gnulib has since been fixed to guarantee that
the snprintf module will always guarantee the constraints needed
by libintl.
Also, we want to guarantee that strdup sets errno on failure.
* .gnulib: Update to latest, for vsnprintf fix.
* bootstrap.conf (gnulib_modules): Add vsnprintf, strdup-posix.
Reported by Matthias Bolte.

v3: more gnulib updates, also fix strdup
v2: see https://www.redhat.com/archives/libvir-list/2011-July/msg00042.html
* .gnulib 7269b35...8db4963 (23):
> sys_select: define sigset_t more portably
> * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Poison pselect.
> pselect: Use pthread_sigmask, not sigprocmask.
> modules/pselect: Add Bruno and Jim to maintainers.
> * modules/pselect: Add select, LIBSOCKET.
> * lib/pselect.c (pselect): Use plain name, without "rpl_".
> pselect: document better
> pthread_sigmask: new module
> test-pselect: new module
> * tests/test-sys_select.c (sigset_t): Test for it, too.
> snprintf: guarantee %1$d, for libintl
> maint: exempt stdio-read.c and stdio-write.c from the cppi check
> maint: indent with spaces, not TABs, and add a rule to check this
> maint.mk: correct omissions in prohibit_argmatch_without_use check
> Comments about EINTR.
> autoupdate
> xnanosleep: Rewrite to use new dtotimespec module.
> timespec-add, timespec-sub: new modules
> dtotimespec: new module
> * lib/timespec.h (timespectod): New inline function.
> * lib/timespec.h (timespec_sign): New inline function.
> pselect: new module
> sys_select: don't depend on sys_socket
I'm also investigating how easy it would be to use gnulib's new
pthread_sigmask.

[libvirt] [PATCH] Do not drop kernel cmdline for xen pv domains
by Jim Fehlig
Kernel cmdline args can be passed to xen pv domains even when a
bootloader is specified. The current config-to-sxpr mapping
ignores cmdline when bootloader is present.
Since the xend sub-driver is used with many xen toolstack versions,
this patch takes conservative approach of adding an else block to
existing !def->os.bootloader, and only appends sxpr if def->os.cmdline
is non-NULL.
