CVS commit: src/sys/dev
Module Name:src Committed By: isaki Date: Sat Sep 2 13:28:11 UTC 2017 Modified Files: src/sys/dev: audio.c Log Message: Remove duplicated code. For hwvc, audio_calc_blksize() appears soon again. For user vc, the userland format and HW format are separeted, so audio_calc_blksize() here is no longer necessary. In addition, vc->sc_mpr.blksize is already initialized in audio_open().

CVS commit: src/sys
Module Name:src Committed By: maxv Date: Sat Sep 2 12:57:03 UTC 2017 Modified Files: src/sys/arch/amd64/amd64: gdt.c src/sys/arch/i386/i386: gdt.c src/sys/compat/linux32/arch/amd64: linux32_machdep.c Log Message: Fix a subtle ring0 escalation vulnerability in amd64, and implement a mitigation against similar bugs. The operations on segment registers can generate a page fault if there is an issue when touching the in-memory gdt. Theoretically, it is never supposed to happen, since the gdt is mapped correctly. However, in the kernel we allow the gdt to be resized, and to do that, we allocate the maximum amount of va needed by it, but only kenter a few pages until we need more. Moreover, to avoid reloading the gdt each time we grow it, the 'size' field of gdtr is set to the maximum value. All of this means that if a mov or iretq is done with a segment register whose index hits a page that has not been kentered, a page fault is sent. Such a page fault, if received in kernel mode, does not trigger a swapgs on amd64; in other words, the kernel would be re-entered with the userland tls. And there just happens to be a place in compat_linux32 where the index of %cs is controlled by userland, making it easy to trigger the page fault and get kernel privileges. The mitigation simply consists in abandoning the gdt_grow mechanism and allocating/kentering the maximum size right away, in such a way that no page fault can be triggered because of segment registers.
