* generic: 5.15: enable Werror by default for kernel compileChristian Marangi2023-05-121-1/+1
| | | | | | | | From 5.15 and up linux kernel introduced CONFIG_WERROR to flag any warning as error. To improve code quality, enable this by default to catch any warning and fix it. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
* generic: 5.15: remove outdated symbolsNick Hainke2023-05-051-8/+0
| | | | | | | | | | | | | Remove symbols that are no longer present in 5.15: - CONFIG_CRYPTO_RMD128 - CONFIG_CRYPTO_RMD256 - CONFIG_CRYPTO_RMD320 - CONFIG_CRYPTO_SALSA20 - CONFIG_CRYPTO_TGR192 - CONFIG_RAW_DRIVER - CONFIG_ENABLE_MUST_CHECK Signed-off-by: Nick Hainke <vincent@systemli.org>
* kernel: fix handling of CONFIG_DYNAMIC_DEBUGTony Ambardar2023-05-031-1/+1
| | | | | | | | | | Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG setting in Config-kernel.in (default N), remove or disable it in target configs which unconditionally enable it, along with the related setting CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
* kernel: Activate CONFIG_SLAB_FREELIST_RANDOMHauke Mehrtens2023-05-031-1/+1
| | | | | | | | | | | | | This activates CONFIG_SLAB_FREELIST_RANDOM. This option make the free list less predictable. This makes it harder to exploit heap based security vulnerabilities. This adds a little bit more code to the kernel and a small additional compute overhead. This option is activated in Debian by default. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Activate CONFIG_SCHED_STACK_END_CHECKHauke Mehrtens2023-04-291-1/+1
| | | | | | | | | | | This activates the CONFIG_SCHED_STACK_END_CHECK option. The kernel will check if the kernel stack overflowed in the schedule() function. This just adds a very small computational overhead. This option is activated in Debian by default. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Activate CONFIG_SLAB_FREELIST_HARDENEDHauke Mehrtens2023-04-291-1/+1
| | | | | | | | | | This activates some extra checks in SLAB or SLUB to make it harder to execute kernel heap exploits. This adds a minor performance degradation which I haven't measured-. Many mainstream Linux distributions also activate this option. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Initialize RNG using CPU RNG and bootloaderHauke Mehrtens2023-04-291-2/+2
| | | | | | | | | | | | | | | | | | | This activates the following kernel options by default: * CONFIG_RANDOM_TRUST_CPU * CONFIG_RANDOM_TRUST_BOOTLOADER With these option Linux will also use data from the CPU RNG e.g. RDRAND and the bootloader to initialize the Linux RNG if such sources are available. These random bits are used in addition to the other sources, no other sources are getting deactivated. I read that the Chacha mixer isn't vulnerable to injected entropy, so this should not be a problem even if these sources might inject bad random data. The Linux kernel suggests to activate both options, Debian also activates them. This does not increase kernel code size. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: disable CONFIG_HW_RANDOM_BCM2835Álvaro Fernández Rojas2023-04-101-0/+1
| | | | | | This HW RNG is present on some Broadcom 63XX SoCs, but not all of them. Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
* kernel: backport NVMEM patches queued for the v6.4Rafał Miłecki2023-04-061-0/+2
| | | | | | | | | They add NVMEM layouts support. It allows handling NVMEM content independently of NVMEM device access. Skip U-Boot env data patch for now as it break our downstream MAC hacks. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* kernel: Deactivate options shown with CONFIG_KERNEL_KCOV=yHauke Mehrtens2023-03-191-0/+1

| | | | | | | | | | The CONFIG_PPC_QUEUED_SPINLOCKS configuration option is not defined for kernel 5.15, it is defined for kernel 5.10. This fixes the compilation of mpc85xx/p2020 with kernel 5.15. Reviewed-by: Robert Marko <robimarko@gmail.com> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: add kmod-lib-842Tony Butler2023-01-281-0/+1
| | | | | | | | | | "842" is a compression scheme and this is the software implementation which is too slow to really use beyond a proof of concept. It can be selected in ZRAM, ZSWAP, or `fs/pstore`, and is here for completeness. In general you need a Power8 or better with 842-in-hardware for it to be fast, but other 842-accelerators are emerging. Signed-off-by: Tony Butler <spudz76@gmail.com>

| | | | | | | | | | Kernel 5.15.82 added a prompt for the FUNCTION_ERROR_INJECTION symbol. This is exposed in builds with CONFIG_KERNEL_KPROBES enabled, causing those builds to fail due to a missing symbol. Add the symbol to fix this.

| | | | | | | | | | | | | | | For kernel versions before 5.2, the required IPsec modes have to be enabled explicitly (they are built-in for newer kernels). Commit 1556ed155a9a ("kernel: mode_beet mode_transport mode_tunnel xfram modules") tried to handle this, but it does not really work. Since we don't support these kernel versions anymore and the code is also broken, let's remove it.

* kernel: disable CONFIG_CPU_LITTLE_ENDIAN in generic configAleksander Jan Bajkowski2022-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Endianness depends on CPU architecture. CONFIG_CPU_(BIG/LITTLE)_ENDIAN should be enabled on target or subtarget based on SoC architecture. Fixes warning: $ make kernel_oldconfig CONFIG_TARGET=subtarget ... .config:1008:warning: override: CPU_LITTLE_ENDIAN changes choice state .... Summary: - ARC - only the CONFIG_CPU_BIG_ENDIAN symbol is defined for this architeture. If it is disabled then the processor operates in LITTLE_ENDIAN mode (default), - ARM32 - CONFIG_CPU_LITTLE_ENDIAN symbol available since kernel 5.19. This option should be enabled after OpenWRT moves to kernel 6.x. After refreshing the kernel, the symbol disappears, - ARM64 - enabled CONFIG_CPU_LITTLE_ENDIAN, - MIPS - enabled relevant symbols, - POWERPC - enabled CONFIG_CPU_BIG_ENDIAN, - UML - Symbols are not defined for this architecture, - X86 - always little endian. Symbols are not defined for this architecture. Signed-off-by: Aleksander Jan Bajkowski <olek2@wp.pl>
