Subject: [RFCv2 PATCH 00/18] refcount_t API + usage
Changes since v1:
- kref INIT fixes are moved to a proper separate commit
- Peter's commits are now properly integrated into series
- various small fixes are incorporated based on testing
results and feedback
This patch series is build on top of Peter's Zijlstra patches
that provide refcount_t type and API definition.
The rest of patches convert various places of kernel subsystems
where atomic_t was used for reference counting to new refcount_t type and API.
By doing this, we make sure that underflows and overflows
cannot occur in these places and therefore no use-after-free situation
can be created and misused by an attacker.
The patches still have a number of rough places, where we especially
would need a feedback. The patches also do not cover absolutely all
cases where atomic_t is used as refcounter. The more complex places
are left for the future patch series and their occurences are documented in
https://docs.google.com/document/d/1Gw-SQoxJ3RAofGrkEm7qEyTC48mst3svVjxnVKXyGPs/edit?usp=sharing
The automatic finding of atomic_t variables used as refcounters
was done using Coccinelle (http://coccinelle.lip6.fr/).
We thank Julia Lawall for helping us to get started on this!
Testing and compilation status:
- Compiles on x86, boots to GUI, no warns in the log
- Compiles for arm (defconfig, imx_v6_v7_defconfig), but cannot test
The patches are on top of linux-4.10-rc2. Patches
would greatly benefit from compile proof test and runtime tests
on all arches because of extensive changes.
