* kernel: add KERNEL_DEVMEM and KERNEL_DEVKMEMHauke Mehrtens2016-12-241-0/+14
| | | | | | | | | 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>
* kernel: add KERNEL_DEBUG_PINCTRL and KERNEL_DEBUG_GPIOHauke Mehrtens2016-12-101-0/+8

* x86: bump default kernel partition size to 16MFelix Fietkau2016-11-091-1/+1

* 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. Drop the option to make resulting ext4 filesystems more flexible by default. Signed-off-by: Jo-Philipp Wich <jo@mein.io> Acked-by: Michael Heimpold <mhei@heimpold.de>
* 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.

* mvebu: add sdcard image creation scriptJosua Mayer2016-09-021-1/+1
| | | | | | | | | | | | | | | | Added gen_mvebu_sdcard_img.sh to facilitate creating an fixed-size sdcard image, adding the bootloader and populating it with actual data. Added the required rules for creating a 4GB sdcard image according to this layout: p0: boot (fat32) p1: rootfs (squashfs) p2: rootfs_data (ext4) This should be generic to any mvebu boards that can boot from block storage. Added the new sdcard image to the Clearfog image profile. Signed-off-by: Josua Mayer <josua.mayer97@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> [cleanup]

* apm821xx: use lzma compression for the initramfs imagesChristian Lamparter2016-07-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | The MR24's u-boot takes it sweet time decompressing the LZMA-packed initramfs image. A user reported that compared to the old gzip method in v2: it "takes a ton longer to decompress like 4\x the old boot time for decompression". This patch also fixes a issue with the WNDR4700's initramfs image getting to big and causing the following u-boot crash during the decompression: "Uncompressing Multi-File Image ... Error: inflate() returned -5 out-of-mem or overwrite error - must RESET board to recover" This patch fixes both issues by reverting the MR24's initramfs compression method back to gzip. And choosing to compress the initramfs within the initramfs image as LZMA by default. Cc: chrisrblake93@gmail.com Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

If the variables aren't configured, the current build system username and hostname are used as normal. The motivation for this option is to achive reproducible (bit-for-bit identical) kernel builds of official openwrt releases.

* Configure IPv6 kernel options in config/Config-kernel.inFelix Fietkau2016-01-041-0/+23
| | | | | | | | | | | | | | | | | | | Revision 46834 changed IPv6 support from a module to builtin. But since the configuration of the IPv6 kernel options was left in package/kernel/linux/modules/netsupport.mk, this means that an empty kmod-ipv6 module was still being generated (not packaged). This patch moves the configuration of the IPv6 kernel options to config/Config-kernel.in to remove this last bit of the module. Note that CONFIG_IPV6_PRIVACY was dropped (enabled by default since Linux v3.13), so this option is no longer needed.

* build: disable kernel stack protector support for i386/x86_64Felix Fietkau2015-08-021-0/+1
| | | | | | | | | | | | When stack protector support is disabled in libc (always the case for !musl), gcc assumes that it needs to use __stack_chk_guard for the stack canary. This causes kernel build errors, because the kernel is only set up to handle TLS stack canaries. Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 46543

| | | | | | | | | | | Make musl provide libssp_nonshared.a and make GCC link it unconditionally if musl is used. This should be a no-op if SSP is disabled and seems to be the only reliable way of dealing with SSP over all packages due to the mess that is linkerflags handling in packages.
