Revert "revocable: Add Kunit test cases"This reverts commit cd7693419bb5abd91ad2f407dab69c480e417a61.The new revocable functionality is fundamentally broken and at a minimumneeds to be redesigned.Drop the revocable Kunit tests to allow the implementation to be reverted.Signed-off-by: Johan Hovold Link: https://patch.msgid.link/20260204142849.22055-3-johan@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/base/Makefile

Tue, 03 Feb 2026 13:30:37 +0100

driver core: disable revocable code from buildThe revocable code is still under active discussion, and there is noin-kernel users of it. So disable it from the build for now so that noone suffers from it being present in the tree, yet leave it in thesource tree so that others can easily test it by reverting this commitand building off of it for future releases.Acked-by: Danilo Krummrich Link: https://patch.msgid.link/2026020307-rimmed-dreamy-5a67@gregkhReviewed-by: Tzung-Bi Shih Signed-off-by: Greg Kroah-Hartman List of files: /linux/drivers/base/Makefile

Fri, 16 Jan 2026 09:02:34 +0100

revocable: Add Kunit test casesAdd Kunit test cases for the revocable API.The test cases cover the following scenarios:- Basic: Verifies that a consumer can successfully access the resource provided via the provider.- Revocation: Verifies that after the provider revokes the resource, the consumer correctly receives a NULL pointer on a subsequent access.- Try Access Macro: Same as "Revocation" but uses the REVOCABLE_TRY_ACCESS_WITH() and REVOCABLE_TRY_ACCESS_SCOPED().A way to run the test:$ ./tools/testing/kunit/kunit.py run \ --kconfig_add CONFIG_REVOCABLE_KUNIT_TEST=y \ revocable_testSigned-off-by: Tzung-Bi Shih Link: https://patch.msgid.link/20260116080235.350305-3-tzungbi@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/base/Makefile

62eb557580eb2177cf16c3fd2b6efadff297b29a - revocable: Revocable resource management

Fri, 16 Jan 2026 09:02:33 +0100

revocable: Revocable resource managementSome resources can be removed asynchronously, for example, resourcesprovided by a hot-pluggable device like USB. When holding a referenceto such a resource, it's possible for the resource to be removed andits memory freed, leading to use-after-free errors on subsequent access.The "revocable" mechanism addresses this by establishing a weak referenceto a resource that might be freed at any time. It allows a resourceconsumer to safely attempt to access the resource, guaranteeing that theaccess is valid for the duration of its use, or it fails safely if theresource has already been revoked.The implementation uses a provider/consumer model built on SleepableRCU (SRCU) to guarantee safe memory access:- A resource provider, such as a driver for a hot-pluggable device, allocates a struct revocable_provider and initializes it with a pointer to the resource.- A resource consumer that wants to access the resource allocates a struct revocable which acts as a handle containing a reference to the provider.- To access the resource, the consumer uses revocable_try_access(). This function enters an SRCU read-side critical section and returns the pointer to the resource. If the provider has already freed the resource, it returns NULL. After use, the consumer calls revocable_withdraw_access() to exit the SRCU critical section. The REVOCABLE_TRY_ACCESS_WITH() and REVOCABLE_TRY_ACCESS_SCOPED() are convenient helpers for doing that.- When the provider needs to remove the resource, it calls revocable_provider_revoke(). This function sets the internal resource pointer to NULL and then calls synchronize_srcu() to wait for all current readers to finish before the resource can be completely torn down.Acked-by: Danilo Krummrich Signed-off-by: Tzung-Bi Shih Link: https://patch.msgid.link/20260116080235.350305-2-tzungbi@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/base/Makefile
