| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the Kconfig fragments in kernel/configs and arch/*/configs that aren't used internally aren't discoverable through "make help", which consists of hard-coded lists of config fragments. Instead, list all the fragment targets that have a "# Help: " comment prefix so the targets can be generated dynamically. Add logic to the Makefile to search for and display the fragment and comment. Add comments to fragments that are intended to be direct targets.

|/ | | | | | | | | | | | | | | | | | | | Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs") promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS within a couple of releases, but five years later this still has not happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs. Get rid of it mechanically: git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' | xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/' Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't regenerated their config file in the last five years will need to just get the new name right when they do.

* random: use random.trust_{bootloader,cpu} command line option onlyJason A. Donenfeld2022-11-183-5/+0
| | | | | | | | | | | | It's very unusual to have both a command line option and a compile time option, and apparently that's confusing to people. Also, basically everybody enables the compile time option now, which means people who want to disable this wind up having to use the command line option to ensure that anyway. So just reduce the number of moving pieces and nix the compile time option in favor of the more versatile command line option. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* random: remove CONFIG_ARCH_RANDOMJason A. Donenfeld2022-07-181-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When RDRAND was introduced, there was much discussion on whether it should be trusted and how the kernel should handle that. Initially, two mechanisms cropped up, CONFIG_ARCH_RANDOM, a compile time switch, and "nordrand", a boot-time switch. Later the thinking evolved. With a properly designed RNG, using RDRAND values alone won't harm anything, even if the outputs are malicious. Rather, the issue is whether those values are being *trusted* to be good or not. And so a new set of options were introduced as the real ones that people use -- CONFIG_RANDOM_TRUST_CPU and "random.trust_cpu". With these options, RDRAND is used, but it's not always credited. So in the worst case, it does nothing, and in the best case, maybe it helps. Along the way, CONFIG_ARCH_RANDOM's meaning got sort of pulled into the center and became something certain platforms force-select. The old options don't really help with much, and it's a bit odd to have special handling for these instructions when the kernel can deal fine with the existence or untrusted existence or broken existence or non-existence of that CPU capability. Simplify the situation by removing CONFIG_ARCH_RANDOM and using the ordinary asm-generic fallback pattern instead, keeping the two options that are actually used. For now it leaves "nordrand" for now, as the removal of that will take a different route.

Since the removal of the Xen tmem driver in 2019, the cleancache hooks are entirely unused, as are large parts of frontswap. This series against linux-next (with the folio changes included) removes cleancaches, and cuts down frontswap to the bits actually used by zswap. This patch (of 13): The cleancache subsystem is unused since the removal of Xen tmem driver in commit 814bbf49dcd0 ("xen: remove tmem driver").

|/ | | | | | | | | | | | | | The HiperSockets Converged Interface (HSCI) introduced with commit 4e20e73e631a ("s390/qeth: Switchdev event handler") requires CONFIG_SWITCHDEV=y to be usable. Similarly when using Linux controlled SR-IOV capable PF devices with the mlx5_core driver CONFIG_SWITCHDEV=y as well as CONFIG_MLX5_ESWITCH=y are necessary to actually get link on the created VFs. So let's add these to the defconfig to make both types of devices usable. Note also that these options are already enabled in most current distribution kernels.

* s390/configs: change CONFIG_VIRTIO_CONSOLE to "m"Thomas Huth2021-04-302-2/+2
| | | | | | | | | | | | | | | | | | In former times, the virtio-console code had to be compiled into the kernel since the old guest virtio transport had some hard de- pendencies. But since the old virtio transport has been removed in commit 7fb2b2d51244 ("s390/virtio: remove the old KVM virtio transport"), we do not have this limitation anymore. Commit bb533ec8bacd ("s390/config: do not select VIRTIO_CONSOLE via Kconfig") then also lifted the hard setting in the Kconfig system, so we can finally switch the CONFIG_VIRTIO_CONSOLE knob to compile this driver as a module now, making it more flexible for the user to only load it if it is really required.

* s390/cio: add CRW inject functionalityVineeth Vijayan2021-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the mechanism to inject artificial events to the CIO layer. One of the main-event type which triggers the CommonIO operations are Channel Report events. When a malfunction or other condition affecting channel-subsystem operation is recognized, a Channel Report Word (consisting of one or more CRWs) describing the condition is made pending for retrieval and analysis by the program. The CRW contains information concerning the identity and state of a facility following the detection of the malfunction or other condition. The patch introduces two debugfs interfaces which can be used to inject 'artificial' events from the userspace. It is intended to provide an easy means to increase the test coverage for CIO code. And this functionality can be enabled via a new configuration option CONFIG_CIO_INJECT. The newly introduces debugfs interfaces can be used as mentioned below to generate different fake-events. To use the crw_inject, first we should enable it by using enable_inject interface. i.e echo 1 > /sys/kernel/debug/s390/cio/enable_inject After the first step, user can simulate CRW as follows: echo <solicited> <overflow> <chaining> <rsc> <ancillary> <erc> <rsid> \ > /sys/kernel/debug/s390/cio/crw_inject Example: A permanent error ERC on CHPID 0x60 would look like this: echo 0 0 0 4 0 6 0x60 > /sys/kernel/debug/s390/cio/crw_inject and an initialized ERC on the same CHPID: echo 0 0 0 4 0 2 0x60 > /sys/kernel/debug/s390/cio/crw_inject Signed-off-by: Vineeth Vijayan <vneethv@linux.ibm.com> Reviewed-by: Peter Oberparleiter <oberpar@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
