This would be a very nice +feature: being able to just restart the ethernet driver; we've just not taken +the time to fix it yet, but it shouldn't be very hard. The code begins at `hurd/pfinet/ethernet.c`, `ethernet_open()`, the `device_open` call, which produces `edev->ether_port`. Basically, one needs to catch errors like EIEIO when using it, and in that case re-open the device. +* Add a futex kernel trap to GNU Mach. This can be useful for nicer locking primitives, including inter-process primitives. `vm_allocate` can be used as an example in the `gnumach` source tree for how to add a kernel trap. +* Add a `task_set_name` RPC to GNU Mach. Currently the Mach debugger keeps `arg[0]` from the stack with ugly heuristics. It would be far better to let `exec` simply set the name. `thread_create` can be used as an example in the `gnumach` source tree for how to add an RPC. glibc needs to be recompiled against the updated mach.defs to get access to it from userland. +* Write a partfs translator, to which one gives a disk image, and which exposes the partitions of the disk image, using parted, and the parted-based storeio (`settrans -c foos1 /hurd/storeio -T typed part:1:file:/home/samy/tmp/foo`) +* Write virtio drivers for KVM. Ideally they would be userland. +* Port valgrind. There is a +[[GSoC proposal|community/gsoc/project_ideas/valgrind ]] about this. + <a name="porting"></a> ## Porting Packages |
