Linux squake security hole (provides root if squake is installed mode 4755)
..., I just thought
you might like to know of this hole.
I''m not totally certain how to exploit this, and it may not be
exploitable. But I''d bet money that it is exploitable and I figured you''d
like to know before BUGTRAQ. Anyways, now for the explanation.
Zoid moved my vga_init() call, which was in the .c file with the
linux main(), into the svgalib .c file, apparently. While this is more
"clean," (esp. considering my stupd inclusion of vga_init() { } into the
X-specific .c files). The problem is that any program using svgalib
requires to be setuid root. vga_...

[PATCH 3/3] drm/nouveau: Skip vga_fini on non-PCI device
As with vga_init, this function doesn't make sense on non-PCI devices,
and the Thunderbolt check in it dereferences a NULL pointer in that
case. Add some code to skip this function when the device is not a PCI
device.

[PATCH 1/3] drm/nouveau/tegra: Skip manual unpowergating when not necessary
On Tegra186, powergating is handled by the BPMP power domain provider
and the "legacy" powergating API is not available. Therefore skip
these calls if we are attached to a power domain.

[PATCH] ioemu/qemu vga: save and restore vram buffer
The existing stdvga driver from xen-unstable tools/ioemu/hw/vga* does
not save the emulated VGA memory contents. The symptoms include video
malfunction after restore, including black screen (which can often be
fixed by asking the guest to redraw) but also missing font setup etc.
The attached patch fixes this by saving the entire VGA memory buffer,
just like the Xen ioemu Cirrus emulator does.
