* build: add a config option for enabling a testing version of the target kernelFelix Fietkau2019-05-111-0/+9
| | | | | | | If the target supports a newer kernel version that is not used by default yet, it can be enabled with this option Signed-off-by: Felix Fietkau <nbd@nbd.name>
* config: kernel: Add KPROBE_EVENTS config optionPetr Štetiar2019-05-051-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Upstream has renamed KPROBE_EVENT to KPROBE_EVENTS in the following commit: commit 6b0b7551428e4caae1e2c023a529465a9a9ae2d4 Author: Anton Blanchard <anton@samba.org> Date: Thu Feb 16 17:00:50 2017 +1100 perf/core: Rename CONFIG_[UK]PROBE_EVENT to CONFIG_[UK]PROBE_EVENTS We have uses of CONFIG_UPROBE_EVENT and CONFIG_KPROBE_EVENT as well as CONFIG_UPROBE_EVENTS and CONFIG_KPROBE_EVENTS. Consistently use the plurals. So I'm adding this plural option in order to make kconfig happy and stop asking about it if kernel is compiled with verbose logging: Enable kprobes-based dynamic events (KPROBE_EVENTS) [Y/n/?] (NEW) Signed-off-by: Petr Štetiar <ynezz@true.cz>

* config: kernel: Fix missing symbol on brcm2708 with CGROUPSDaniel F. Dickinson2019-02-171-0/+14
| | | | | | | | | | | | | | When CGROUP block io is enabled a new symbol is exposed and needs to be set or unset else kernel oldconfig hangs waiting for input during normal OpenWrt builds. Therefore add sane defaults for this symbol in that case. Also, the defaults brcm2708 are different than generic defaults because the platform's defconfig enables BLK_DEV_THROTTLING by default (in defconfig config from the patches used to match upstream's kernel, not in OpenWrt config-4.xx).

* brcm2708: boot-part feature integrationChristian Lamparter2019-01-241-0/+1
| | | | | | | | | | | | | | This patch adds the boot-part feature which enables the brcm2708 target move from the custom boot partition size config option to the generic CONFIG_TARGET_KERNEL_PARTSIZE. Note: For people using custom images: Just like with CONFIG_TARGET_ROOTFS_PARTSIZE changing the value can cause sysupgrade to repartition the device! Make sure to have a backup in this case.

* apm821xx: sata: boot-part feature integrationChristian Lamparter2019-01-011-0/+1
| | | | | | | | | | | | This patch adds the boot-part feature to the apm82181 sata target. This makes it possible to configure the boot partition size with the generic CONFIG_TARGET_KERNEL_PARTSIZE symbol. Please note: For people using custom images: Just like with CONFIG_TARGET_ROOTFS_PARTSIZE changing the value can cause sysupgrade to repartition the device!

* kernel: Fix KERNEL_STACKPROTECTOR on kernel 4.19Hauke Mehrtens2018-12-261-0/+8
| | | | | | | | | | | | The configuration option was renamed with kernel 4.19 from CONFIG_CC_STACKPROTECTOR to CONFIG_STACKPROTECTOR adapt the code to set both options. CONFIG_STACKPROTECTOR now sets the regular stack protector and CONFIG_STACKPROTECTOR_STRONG activates the additional protection of more functions. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* sunxi: fix build without ext4 rootfsAndre Heider2018-09-291-1/+1
| | | | | | | | | | | | The sdcard image generation uses CONFIG_TARGET_ROOTFS_PARTSIZE, which is currently bound to TARGET_ROOTFS_EXT4FS on this target. Since the rootfs is squashfs anyway, allow deselecting of the ext4fs one. Sort the target list alphabetically while here. Signed-off-by: Andre Heider <a.heider@gmail.com>

* config: extend small_flash featureAlex Maclean2018-07-122-3/+9
| | | | | | | | | | Extend the small_flash feature to disable swap, core dumps, and kernel debug info, and change the squashfs block size to 1024KiB. Also change squashfs fragment cache to 2 for small_flash to ease memory usage. Signed-off-by: Alex Maclean <monkeh@monkeh.net>
* kernel: only optimized for size if small_flashMathias Kresin2018-07-121-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin <dev@kresin.me>

* build: cleanup SSP_SUPPORT configure optionJulien Dusser2018-01-271-2/+2
| | | | | | | | | | | | | | | | | | Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh, avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain and depends it means 'build gcc with libssp'. Musl no longer uses libssp (1877bc9d8f), it has internal support, so SSP_SUPPORT was disabled leading some package to not use SSP. No information why Glibc and uClibc use libssp, but they may also provide their own SSP support. uClibc used it own with commit 933b588e25 but it was reverted in f3cacb9e84 without details. Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT if either USE_MUSL or GCC_LIBSSP. Signed-off-by: Julien Dusser <julien.dusser@free.fr>
* build: add hardened builds with PIE (ASLR) supportJulien Dusser2018-01-271-0/+16
| | | | | | | | | | | | | | | | | | Introduce a configuration option to build a "hardened" OpenWrt with ASLR PIE support. Add new option PKG_ASLR_PIE to enable Address Space Layout Randomization (ASLR) by building Position Independent Executables (PIE). This new option protects against "return-to-text" attacks. Busybox need a special care, link is done with ld, not gcc, leading to unknown flags. Set BUSYBOX_DEFAULT_PIE instead and disable PKG_ASLR_PIE. If other failing packages were found, PKG_ASLR_PIE:=0 should be added to their Makefiles. Original Work by: Yongkui Han <yonhan@cisco.com> Signed-off-by: Julien Dusser <julien.dusser@free.fr>

* config: support new symbol intro'd in kernel 4.12Koen Vandeputte2018-01-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Symbol CONFIG_INITRAMFS_FORCE allows to ignore the value passed by the bootloader. By default, all symbols containing INITRAMFS are wiped from the final config and then re-added conditionally. Add support for this symbol, as the build will stop otherwise questioning the user about this option: * Restart config... * * * General setup * Cross-compiler tool prefix (CROSS_COMPILE) [] Compile also drivers which will not load (COMPILE_TEST) [N/y/?] n ...

Currently CONFIG_ALL_KMODS is not selected when the build bot selects CONFIG_ALL_NONSHARED for example. Now the rtc kmods should get build when CONFIG_ALL_KMODS, CONFIG_ALL_NONSHARED or CONFIG_ALL and CONFIG_RTC_SUPPORT are selected like it is done by the build bots for targets with rtc support.

* x86: Set default baud rate on Geode images to 115200David Woodhouse2017-02-171-1/+0
| | | | | | | | | | | Prior to commit 1496b95a0 ("x86: clean up default grub baudrate settings") we had three different baud rates for the Geode targets: 19200 for net5501, 38400 for alix2, and 115200 for Geos. It doesn't seem that there's a very good reason for varying from our default 115200 baud, so let's make the Geode target do that instead. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* build: add buildbot specific config option for setting defaultsFelix Fietkau2017-02-141-2/+12
| | | | | | | | | | This can be used to tweak the buildbot behavior without having to change buildbot's configuration. It will also allow us to add more aggressive clean steps (e.g. on toolchain changes), which would break developers' workflows if enable by default. Signed-off-by: Felix Fietkau <nbd@nbd.name>

* build: add support for automatically removing build dir contents during buildFelix Fietkau2017-01-181-0/+8

| | | | | | | | | These options are needed to create /dev/mem or /dev/kmem . /dev/mem is needed by the io tool to access raw hardware memory, which is helpful when debugging and developing drivers. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: John Crispin <john@phrozen.org>
* x86: revert default root size back to 256 MBFelix Fietkau2016-12-151-2/+1
| | | | | | | | | | | 2 GB is overkill and was only added to allow unlimited ext4 resizing, which is a pretty rare use case. 256 MB allows resizing up to 256 GB, which should be good enough for almost all users. A lot of this is mostly irrelevant anyway, since you can just use squashfs + ext4 overlay. Signed-off-by: Felix Fietkau <nbd@nbd.name>

* config: ext4: increase x86 rootfs size to 2GB to support online resize2fsJo-Philipp Wich2016-10-271-1/+2
| | | | | | | | | | | | | | | | | | | The current default rootfs size of 256MB in conjunction with 4K blocks produces an ext4 filesystem which lacks the appropriate amount of backup GDT entries to support online-resizing. For x86 targets, increase the default rootfs size to 2048MB which allows online resizing the filesystem to up to 2TB which is the current theoretical maximum for LEDE, due to missing GPT support on the root block device. Note that the filesystem artefact will not occupy 2GB on the build system as the make_ext4fs utility uses sparse files to generate the filesystem images, so the actual disk usage is much lower. Furthermore the filesystem images are gzip compressed, shrinking them to only a few megabytes on the download server.

* config: ext4: drop option to set maximum number of inodesJo-Philipp Wich2016-10-271-7/+0
| | | | | | | | | | | There is very little practical use to limit the number of available inodes on an ext4 filesystem and the make_ext4fs utility is able to calculate useful defaults by itself.

* config: enable shadow passwords unconditionallyMatthias Schiffer2016-09-261-3/+0
| | | | | | | | | | | | | Configurations without shadow passwords have been broken since the removal of telnet: as the default entry in /etc/passwd is not empty (but rather unset), there will be no way to log onto such a system by default. As disabling shadow passwords is not useful anyways, remove this configuration option. The config symbol is kept (for a while), as packages from feeds depend on it.
