[PATCH] launch: libvirt: Implement drive secrets (RHBZ#1159016).
by Richard W.M. Jones
Implement the GUESTFS_ADD_DRIVE_OPTS_SECRET argument of
guestfs_add_drive_opts. For libvirt we have to save the secret in
libvirtd first, get a UUID, and then pass the UUID back through the
domain XML.

[libhivex] Undefined behavior when accessing invalid (too small) registry hives
by Mahmoud Al-Qudsi
Hello all,
I know that one of the original design goals of libhivex was to be
resilient to corrupt, invalid, or malicious registry hives. I've
encountered some undefined behavior in libhivex when attempting to open
registry files that are too small. I'm not sure if this is a known issue
per-se or not, so I figured I'd ask here on the mailing list before I
jumped in and started adding out-of-bounds checks everywhere.
The simplest test case is when attempting to open a zero-byte registry
file, handle.c will mmap a zero-byte file and then go out of bounds while
comparing against the registry header ("regf"). I imagine even if you pass
in a 4-byte file, the header checksum calculation will loop over 0x7F
bytes, so you'd probably encounter another error there. I guess I'm just
not sure where the ideal location(s) to place range-checking would be; is
there anything smarter than plastering checks at every read/write to the
registry file?
Or is it expected that certain sanity checks would be performed prior to
passing along any files to libhivex? What would those checks be?
Thank you,
Mahmoud Al-Qudsi

It's simply not possible to make it work without the NFS server.
That's just how it works. I suggest you need to ask whoever runs your
NFS server to fix it so it has more capacity.
BTW 1.27.64, uploading later today, will fix some Windows conversion bugs.

[... and many more ...]
The command should work.
However what version of libguestfs? What distro? Did you compile it
yourself or get it from some package? GCC 4.1.2 dates from 2007, so
I'm guessing that you are trying this on something very old.
Rich.

[PATCH v2] daemon: Remove custom Augeas lenses.
by Richard W.M. Jones
v2 of previous patch, which fixes some missing bits.
For now I'm going to go with Pino's RHEL 7.1 patch, since it
is at least smaller than this. So I'm sending this to the list
just to have it archived for later.

[PATCH] daemon: Remove custom Augeas lenses.
by Richard W.M. Jones
Don't carry around Augeas lenses. It is fragile, since if the lens is
added to upstream Augeas but the version number has not changed, then
Augeas won't parse the target file at all. This specifically causes
password adjustments to fail in RHEL 7.1.
In future, if we need an Augeas lens, it must be added to Augeas,
either upstream or as a downstream patch carried around by distros.
