Xemul moved page Compel TODO before release to Compel TODO: Released already
[[Category: Compel]]
[[Category: Compel]]
{{Note|[[Compel]] is already released}}
==== Check and fix non-x86 arches ====
CRIU works with compel just fine, but standalone mode is verified by tests on x86 only.
==== Fix "root-only" obstacle ====
CRIU is root-only tool, so we've only checked compel to work when used by root-capable tasks. However, making it work from non-root user is possible, not that hard and makes perfect sense.
==== Tune the API ====
Right now we have some stuff that just got into compel/include/uapi/ when we moved the code around and should be hidden. Naming could probably be better too. Configuring the infection context is also FIXME-able.
==== Fix the compel_main environment ====
Currently compel parasite code is RPC-only, but there are signs of compel_main (e.g. __export_std_compel_start). Need to clean this out.
==== Rectify parasite loading ====
For now the prepared parasite ELF should be converted into a C header file, then compiled with infection code, then libcompel can inject it into victim. Reorganizing the code so that it loads the ELF itself is tempting.
: {{Done}} Made C-header loading MUCH nicer with pre-generated macros.
==== Make .so version of the library ====
For now the libcompel.a is built, so only static linkage is possible. Making it .so should not be a big deal, it mostly depends on the API rectification task (API should be extendable and backward compatible).
: {{Done}} <code>make compel/libcompel.so</code> works
==== Save/Restore SAS in standalone mode ====
It's currently only handled by CRIU
==== Sanitize logging ====
Nowadays we just set FD to put logs into.
==== Untie task state numbers ====
The TASK_ALIVE and others are literally and numerically coincide between compel and criu.
: {{Done}} <code>COMPEL_TASK_FOO</code>s are in compel and <code>TASK_BAR</code>s are in criu and correspond to each other
