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. https://savannah.gnu.org/task/index.php?6231 +* Add a `task_set_name` RPC to GNU Mach. Currently the Mach +debugger keeps `arg[0]` from the stack with ugly heuristics (see +`gnumach/i386/i386/db_interface.c`, `looks_like_command`...). It would be +far better to let `exec` simply set the name and record it in `task_t`. +`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. exec would probably call it from `hurd/exec/exec.c`, +`do_exec()`. +* 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`). This would be libnetfs-based. +* Write virtio drivers for KVM. Ideally they would be userland. +* Port valgrind. There is a whole +[[GSoC proposal|community/gsoc/project_ideas/valgrind ]] about this, but the +basic port could be small. +* Add a `-E` option to `rpctrace` to specify environment variables: https://savannah.gnu.org/task/index.php?9331 +* Use libz and libbz2 in exec. See `hurd/exec/unzip.c` etc., they should be replaced by mere calls to libraries, https://savannah.gnu.org/task/index.php?6990 +* Add `/proc/$pid/maps`. `vminfo` already has this kind of information, it's a matter of making procfs do the same. https://savannah.gnu.org/bugs/?32770 + + <a name="porting"></a> ## Porting Packages diff --git a/open_issues/glibc.mdwn b/open_issues/glibc.mdwn index ac4d7d12..a92b8642 100644 --- a/open_issues/glibc.mdwn +++ b/open_issues/glibc.mdwn @@ -683,6 +683,8 @@ Last reviewed up to the [[Git mirror's d3bd58cf0a027016544949ffd27300ac5fb01bb8 the fact that EXEC_PAGESIZE is not defined on hurd, libio/libioP.h switches the allocation modes from mmap to malloc + [[!message-id "87mxd9hl2n.fsf@kepler.schwinge.homeip.net"]]. + * `LD_DEBUG` IRC, freenode, #hurd, 2012-11-22 |
