osmo_io_uring: Cancel pending request, free msghdr on completion There is always a completion after cancelling a uring request. Because uring requests use msghdr pointer as user data, we cannot just free the msghdr after cancelling. Upon completion (received after cancelling), the user data still points to the msghdr. To prevent a use-after-free bug, msghdr is not freed, but detached from iofd instance. Then upon completion, the msghdr (if it was detached from iofd) is freed. Additionally it is not required to keep IOFD_FLAG_IN_CALLBACK set anymore, if there is a msghdr attached to iofd. As described above, all msghdr get detached, if iofd is freed (uring request get cancelled) during callback. Related: OS#5751 Change-Id: Ic253f085dd6362db85f029f46350951472210a02
This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.
Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.
There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.
The libosmocore.git repository build multiple libraries:
The official homepage of the project is https://osmocom.org/projects/libosmocore/wiki/Libosmocore
You can clone from the official libosmocore.git repository using
git clone https://gitea.osmocom.org/osmocom/libosmocore
There is a web interface at https://gitea.osmocom.org/osmocom/libosmocore
Doxygen-generated API documentation is generated during the build process, but also available online for each of the sub-libraries at https://ftp.osmocom.org/api/latest/libosmocore/
