I've been testing on the Krita downloads page (it's my normal way of testing running AppImages). No more portal save dialog, just nothing. 636a47c9243a8cf0387b6e2e4fbb7d8972e501f4 is the first bad commit commit 636a47c9243a8cf0387b6e2e4fbb7d8972e501f4 Author: Alyssa Ross <hi(a)alyssa.is> Date: Wed Sep 10 22:06:34 2025 +0200 lib/nixpkgs.default.nix: update to nixos-unstable-small Signed-off-by: Alyssa Ross <hi(a)alyssa.is> host/initramfs/default.nix | 3 ++- host/rootfs/default.nix | 2 +- img/app/default.nix | 2 +- lib/nixpkgs.default.nix | 4 ++-- vm/sys/net/default.nix | 2 +- 5 files changed, 7 insertions(+), 6 deletions(-) So needs a Nixpkgs bisection.

[PATCH v3 1/3] tools/mount-flatpak: init
by Alyssa Ross 30 Nov '25

30 Nov '25

I tried to build this with Meson, but pathrs depends on thiserror, which tries to read OUT_DIR, and support for setting that isn't currently in a Meson release, and requires nightly Rust, so build with Cargo for now and we can revisit that later.

Limitations on Grant Scope + +The licenses granted in this Section 2 are the only rights granted under +this License.

Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6. Disclaimer of Warranty * +* ------------------------- * +* * +* Covered Software is provided under this License on an "as is" * +* basis, without warranty of any kind, either expressed, implied, or * +* statutory, including, without limitation, warranties that the * +* Covered Software is free of defects, merchantable, fit for a * +* particular purpose or non-infringing. The entire risk as to the * +* quality and performance of the Covered Software is with You. * +* Should any Covered Software prove defective in any respect, You * +* (not any Contributor) assume the cost of any necessary servicing, * +* repair, or correction. This disclaimer of warranty constitutes an * +* essential part of this License. No use of any Covered Software is * +* authorized under this License except under this disclaimer. * +* * +************************************************************************ + +************************************************************************ +* * +* 7. Limitation of Liability * +* -------------------------- * +* * +* Under no circumstances and under no legal theory, whether tort * +* (including negligence), contract, or otherwise, shall any * +* Contributor, or anyone who distributes Covered Software as * +* permitted above, be liable to You for any direct, indirect, * +* special, incidental, or consequential damages of any character * +* including, without limitation, damages for lost profits, loss of * +* goodwill, work stoppage, computer failure or malfunction, or any * +* and all other commercial damages or losses, even if such party * +* shall have been informed of the possibility of such damages. This * +* limitation of liability shall not apply to liability for death or * +* personal injury resulting from such party's negligence to the * +* extent applicable law prohibits such limitation. Some * +* jurisdictions do not allow the exclusion or limitation of * +* incidental or consequential damages, so this exclusion and * +* limitation may not apply to You. * +* * +************************************************************************ + +8. Litigation +------------- + +Any litigation relating to this License may be brought only in the +courts of a jurisdiction where the defendant maintains its principal +place of business and such litigation shall be governed by laws of that +jurisdiction, without reference to its conflict-of-law provisions. +Nothing in this Section shall prevent a party's ability to bring +cross-claims or counter-claims. + +9. Miscellaneous +---------------- + +This License represents the complete agreement concerning the subject +matter hereof. If any provision of this License is held to be +unenforceable, such provision shall be reformed only to the extent +necessary to make it enforceable. Any law or regulation which provides +that the language of a contract shall be construed against the drafter +shall not be used to construe this License against a Contributor. + +10. Versions of the License +--------------------------- + +10.1. New Versions + +Mozilla Foundation is the license steward. Except as provided in Section +10.3, no one other than the license steward has the right to modify or +publish new versions of this License. Each version will be given a +distinguishing version number. + +10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version +of the License under which You originally received the Covered Software, +or under the terms of any subsequent version published by the license +steward. + +10.3. Modified Versions + +If you create software not governed by this License, and you want to +create a new license for such software, you may create and use a +modified version of this License if you rename the license and remove +any references to the name of the license steward (except to note that +such modified license differs from this License). + +10.4. Distributing Source Code Form that is Incompatible With Secondary +Licenses + +If You choose to distribute Source Code Form that is Incompatible With +Secondary Licenses under the terms of this version of the License, the +notice described in Exhibit B of this License must be attached. + +Exhibit A - Source Code Form License Notice +------------------------------------------- + + This Source Code Form is subject to the terms of the Mozilla Public + License, v. 2.0.

Sometimes we see a test failure that looks like this: unexpected connection data: qemu-system-aarch64: terminating on signal 15 from pid 184 () I think this is because, now that the nc command in the networking integration test has a timeout, it's possible for it to time out after having opened the connection, but before having written all its input to it. Therefore, ignore connections that send a prefix of the expected data (including nothing), and just wait for the next connection rather than failing if that happens.

[PATCH v2 0/7] spectrum-router
by Yureka Lilian 29 Nov '25

29 Nov '25

Changes since v1 (non-exhaustive): - Use spectrum-router from pkgsMusl - Refactor router into smaller modules - Parse router advertisements from upstream interfaces - Select active upstream interface based on router advertisements - Assign guest mac addresses based hash of vm id - Fix race condition when assigning driver-router interface - Temporarily disable re-write of mac addresses which would be needed for wifi. It will be added back inside the xdp-forwarder in a future patch. and completely new patches: - Change nameserver & default route in app-vm template - Fix integration tests - Leave dbus in net-vm and add iwd for testing Yureka Lilian (7): vm/sys/net: remove connman vm/sys/net: integrate xdp-forwarder vm/sys/net: add iwd tools: add spectrum-router host: integrate router img/app: change to ipv6 nameserver checks/integration: Adapt networking test for ipv6 host/rootfs/default.nix | 4 +- host/rootfs/file-list.mk | 3 + .../data/service/spectrum-router/down | 0 .../template/data/service/spectrum-router/run | 13 + .../image/usr/bin/assign-driver-router-iface | 11 + host/rootfs/image/usr/bin/run-vmm | 12 +- host/rootfs/image/usr/bin/vm-import | 13 - img/app/image/etc/mdev/iface | 17 - img/app/image/etc/resolv.conf | 2 +- pkgs/default.nix | 2 + pkgs/overlay.nix | 1 + release/checks/integration/default.nix | 2 +- release/checks/integration/networking.c | 32 +- tools/router/Cargo.lock | 807 ++++++++++++++++++ tools/router/Cargo.lock.license | 2 + tools/router/Cargo.toml | 21 + tools/router/default.nix | 18 + tools/router/src/main.rs | 73 ++ tools/router/src/packet.rs | 187 ++++ tools/router/src/protocol.rs | 65 ++ tools/router/src/router.rs | 133 +++ tools/router/src/upstream.rs | 170 ++++ tools/start-vmm/ch.rs | 38 +- tools/start-vmm/lib.rs | 76 +- tools/start-vmm/meson.build | 2 +- tools/start-vmm/net-util.c | 39 - tools/start-vmm/net-util.h | 6 - tools/start-vmm/net.c | 55 -- tools/start-vmm/net.rs | 11 - tools/start-vmm/tests/meson.build | 5 - .../start-vmm/tests/tap_open-name-too-long.c | 20 - tools/start-vmm/tests/tap_open.c | 28 - vm/sys/net/Makefile | 2 +- vm/sys/net/default.nix | 15 +- vm/sys/net/file-list.mk | 3 - vm/sys/net/image/etc/fstab | 2 + vm/sys/net/image/etc/mdev/iface | 28 +- vm/sys/net/image/etc/nftables.conf | 16 +- vm/sys/net/image/etc/s6-rc/connman/run | 19 - vm/sys/net/image/etc/s6-rc/connman/type | 1 - .../net/image/etc/s6-rc/connman/type.license | 2 - 41 files changed, 1627 insertions(+), 329 deletions(-) rename vm/sys/net/image/etc/s6-rc/connman/dependencies.d/dbus => host/rootfs/image/etc/s6-linux-init/run-image/service/vm-services/template/data/service/spectrum-router/down (100%) create mode 100755 host/rootfs/image/etc/s6-linux-init/run-image/service/vm-services/template/data/service/spectrum-router/run create mode 100755 host/rootfs/image/usr/bin/assign-driver-router-iface create mode 100644 tools/router/Cargo.lock create mode 100644 tools/router/Cargo.lock.license create mode 100644 tools/router/Cargo.toml create mode 100644 tools/router/default.nix create mode 100644 tools/router/src/main.rs create mode 100644 tools/router/src/packet.rs create mode 100644 tools/router/src/protocol.rs create mode 100644 tools/router/src/router.rs create mode 100644 tools/router/src/upstream.rs delete mode 100644 tools/start-vmm/net-util.c delete mode 100644 tools/start-vmm/net-util.h delete mode 100644 tools/start-vmm/net.c delete mode 100644 tools/start-vmm/tests/tap_open-name-too-long.c delete mode 100644 tools/start-vmm/tests/tap_open.c delete mode 100644 vm/sys/net/image/etc/s6-rc/connman/run delete mode 100644 vm/sys/net/image/etc/s6-rc/connman/type delete mode 100644 vm/sys/net/image/etc/s6-rc/connman/type.license -- 2.51.2
