* treewide: remove files for building 5.10 kernelNick Hainke2023-05-121-7205/+0
| | | | | | | | | | | All targets are bumped to 5.15. Remove the old 5.10 patches, configs and files using: find target/linux -iname '*-5.10' -exec rm -r {} \; Further, remove the 5.10 include. 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>

| | | | | | | | | | | | | | | 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.

* 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>

* kernel: mtdsplit: add support for H3C VFS filesystemJan Hoffmann2022-07-281-0/+1
| | | | | | | | | | | | | | | | The bootloader on some H3C devices (for example HPE 1920 switches) only supports booting from flash by reading an image from an "VFS" filesystem which spans most of the available flash. The filesystem size is hard- coded in the bootloader. However, as long as no write operations are performed in the bootloader menu, it is sufficient if the start of the partition contains a valid filesystem with the kernel image. This mtdsplit parser reads the size and location of the kernel image and finds the location of the rootfs stored after it. It assumes that the filesystem image matches the layout of one generated by mkh3cvfs, with a filename of "openwrt-kernel.bin" for the kernel image. Signed-off-by: Jan Hoffmann <jan@3e8.eu>

* kernel: cut broken SPI_NOR 4K eraseblock LIMIT patchJohn Thomson2022-06-291-1/+0
| | | | | | | | | | | | | | | | | | Since 4e0c54bc5bc8 ("kernel: add support for kernel 5.4"), the spi-nor limit 4k erasesize to spi-nor chips below a configured size patch has not functioned as intended. For uniform erasesize SPI-NOR devices, both nor->erase_opcode & mtd->erasesize are used in erase operations. These are set before, and not modified by, this CONFIG_MTD_SPI_NOR_USE_4K_SECTORS_LIMIT patch. Thus, an SPI-NOR device with CONFIG_MTD_SPI_NOR_USE_4K_SECTORS will always use 4k erasesize (where the device supports it). If this patch was fixed to function as intended, there would be cases where devices change from a 4K to a 64K erasesize. Signed-off-by: John Thomson <git@johnthomson.fastmail.com.au>

* kernel: enable SERIAL_8250_16550A_VARIANTSStijn Tintel2022-03-181-1/+1
| | | | | | | | | | | | | | | | | | | Kernel 5.6 introduced a new config symbol SERIAL_8250_16550A_VARIANTS. In kernel 5.8, this symbol was changed to default to on on !x86, as some embedded devices still use 16650A variants. Let's play safe here and enable this symbol in the generic config, to avoid others from running into this problem and having to spend several hours trying to bisect this problem. While we could disable the symbol in the x86 target configs, a 20ms boot time reduction really isn't worth the time wasted on bisecting this issue. Matt discovered this problem while working on adding support for the WatchGuard Firebox M200 to the qoriq target, where it caused some characters to be missing on the console output.
