...14 Fixed: 2019-09-16 Published: 2019-09-16 There is no CVE number assigned for this issue yet, but the bug is being categorized and processed by Red Hat's security team which may result in a CVE being published later. Description ----------- Libnbd includes the method nbd_set_tls(h, LIBNBD_TLS_REQUIRE) which is documented to let a client refuse to connect to a server that is not using TLS encryption. However, if the server uses the oldstyle protocol, a flaw in libnbd meant that the client would proceed with an unencrypted connection without warning. An attacker, perhaps acting as a man-in-the-...

This series is to allow NVIDIA chips with shared memory to operate more efficiently (and to operate at all once we disable VRAM from the kernel driver) by allowing nouveau_screen to specify a domain to use for objects originally allocated into VRAM. If the domain is not overridden, the default NOUVEAU_BO_VRAM is used. A NV_VRAM_DOMAIN() macro is then introduced to be used in place of

New revision of this patchset that prevents VRAM objects from being allocated on VRAM-less systems like Tegra. This is required for Mesa to work on such systems. Changes since v2: - Use vram_size to detect systems without VRAM and set the correct domain instead of expecting each chip to set its domain explicitly. Alexandre Courbot (2): nouveau: support for custom VRAM domains nvc0: use

Well, the golang changes (patch 1 and 2/3 of v1) were already committed, all that was left was the OCaml changes. I'm a lot happier with how things turned out with an UNKNOWN constructor in the OCaml variants. Eric Blake (3): tests: Enhance coverage of enum/flag range checking ocaml: Support unknown values for Enum/Flags ocaml: Typesafe returns for REnum/RFlags generator/OCaml.ml

Patch 3 still needs tests added, but it is at least working from my simple command line tests. Eric Blake (3): server: Implement nbdkit_is_tls for use during .open server: Expose final thread_model to filter's .get_ready tlsdummy: New filter docs/nbdkit-filter.pod | 21 +- docs/nbdkit-plugin.pod | 34 ++- docs/nbdkit-tls.pod

This is a revision of my .default_export work, plus new work on .export_descriptions and a new exportname filter. I think it is now ready to check in. Things I'd still like in 1.22: - the file plugin should implement .list_exports (patch already posted, but it needs rebasing on this series) - the ext2 filter should override .list_exports when in exportname mode - the nbd plugin should be

It's been several weeks since I posted v2 (I got distracted by improving libnbd to better test things, which in turn surfaced some major memory leak problems in nbdsh that are now fixed). Many of the patches are minor rebases from v2, with the biggest changes being fallout from: - patch 2: rename nbdkit_add_default_export to nbdkit_use_default_export - overall: this missed 1.22, so update
