This can be seen by running `readelf -S file.o | grep GNU-stack | grep X`, for instance that happens in libdiskfs/file-exec.c, libdiskfs/io-revoke.c. We can't really use -fno-trampoline, we should instead add `void *data` parameters to iterators such as `ports_class_iterate` or `fshelp_exec_reauth`, so that the nested functions can be made mere static functions that get their information from the `void *data` parameter. * Implement `pthread_setschedparam` and `sched_setscheduler` in glibc by calling mach's `thread_policy` and `thread_priority`. * Strengthen httpfs: it should append '/' to URL automatically, it should not fallback index.html itself, etc. probably a lot more small easy issues. @@ -101,7 +100,6 @@ with".

It means adding an RPC to proc to implement it, and then making glibc detect when setting `SIG_IGN` on `SIGCLD`, or setting the `SA_NOCLDWAIT` flag, and in that case call into `proc`, similarly to the `S_proc_mod_stopchild` RPC. proc's `S_proc_wait` shall then wait for all children and return `ECHILD`. * Implement `lsof`.

The structure would contain the `fp_save_kind`. That'll actually be needed both on `i386` and `x86_64` actually, to fix SSE use against signals in general. -* Compare testsuite results of python on hurd-i386 and hurd-amd64, to fix regressions between the former and the latter. * Check the [packages build failures differences](https://people.debian.org/~sthibault/hurd-amd64/failed_diff.txt) between hurd-i386 and hurd-amd64: they are failing on hurd-amd64 but are successful on hurd-i386. Possibly it's just a mere missing `s/hurd-i386/hurd-any/` in the debian/ directory, or a new bug that actually also affects hurd-i386 if you rebuild the package there now, but possibly it's a more profound issue in the amd64 port. * On amd64, fix memcpy (> 16 bytes) from `/dev/mem` (makes hurd-console crash) * On amd64, fix crash-core * On amd64, fix running posixtestsuite (not necessarily fixing the tests themselves, but at least make sure it doesn't crash the box ; it could still be useful to compare the output on 32bit and 64bit are the same with the same gnumach/hurd/glibc). * Settle CI for mig+gnumach+hurd+glibc. * Port `dhcpcd`, see [call for help](https://lists.debian.org/debian-hurd/2023/11/msg00030.html) +* Make sure that lwip supports configuration by DHCP. * Extensively test (e.g. running testsuites of glibc, perl, curl, rust-mio) and fix the lwip-based TCP/IP stack, to be sure we don't get regressions by switching to it. -* Fix swapping with `rumpdisk`. +* Fix swapping with `rumpdisk` + * Apparently some wiring cases is not effective, we are seeing pageout of rumpdisk memory. * Fix the [GPLv2 vs GPLv3 licence incompatibility between ext2fs and libparted](https://bugs.debian.org/838244): - * For /hurd/ext2fs, use a different libstoreio that does not include the parted module. + * For /hurd/ext2fs, use a different libstore that does not include the parted module. * For /hurd/ext2fs.static in the bootstrap chain (e.g. to access wd0s1), add a storeio translator before it, and have ext2fs open it, use `file_get_storage_info` and access the underlying device.
