test_sysclt: Test for registering a mount point

2023-06-18T09:32:54+00:00

Test that target gets created by register_sysctl_mount_point and that no additional target can be created "on top" of a permanently empty sysctl table. Create a mount point target (mnt) in the sysctl test driver; try to create another on top of that (mnt_error). Output an error if "mnt_error" is present when we run the sysctl selftests.

testing: use the copyleft-next-0.3.1 SPDX tag

2022-11-08T14:44:02+00:00

Two selftests drivers exist under the copyleft-next license. These drivers were added prior to SPDX practice taking full swing in the kernel. Now that we have an SPDX tag for copyleft-next-0.3.1 documented, embrace it and remove the boiler plate.

test_sysctl: simplify subdirectory registration with register_sysctl()

2022-01-22T06:33:35+00:00

There is no need to user boiler plate code to specify a set of base directories we're going to stuff sysctls under.

lib/test_sysctl: support testing of sysctl. boot parameter

2020-06-08T18:05:56+00:00

Testing is done by a new parameter debug.test_sysctl.boot_int which defaults to 0 and it's expected that the tester passes a boot parameter that sets it to 1. The test checks if it's set to 1. To distinguish true failure from parameter not being set, the test checks /proc/cmdline for the expected parameter, and whether test_sysctl is built-in and not a module.

lib: Make test_sysctl initialized as module

2020-06-02T16:26:14+00:00

test_sysctl.c is expected to be used as a module, but since it does not use module_init(), it never be registered as a module and not appeared under /sys/module/. In the result, the selftests/sysctl/sysctl.sh always fails to find the test module and is skipped. This makes test_sysctl.c initialized as a module by module_init() and allow sysctl.sh to find the test module is loaded.
