* kernel: enable SRv6 support by enabling lwtunnelNick Hainke2021-01-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Enable the ability to use segment routing based on IPv6. It allows the packet to specify a path that the packet should take through the network. Lwtunnel allow an easy encapsulation of a package. You can just install ip-full package and use it: ip -6 route add 2003::/64 dev eth0 encap seg6 mode encap \ segs 2001::1,2002::2 An IPv6 package looks like this: [IPv6 HDR][IPv6 RH][IPv6 HDR][Data...] Netifd support: https://git.openwrt.org/?p=project/netifd.git; a=commit;h=458b1a7e9473c150a40cae5d8be174f4bb03bd39 Increases imagesize by 24.125 KiB.

* kernel: only strip proc for small flash devicesNick Hainke2020-12-221-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, you are not able to get statistics about IPv4 and IPv6 usage. This information can be collected via the snmp and snmp6. However, in the current state this interface is disabled as you can read in the "902-debloat_proc.patch": "Strip non-essential /proc functionality to reduce code size" Tools like netstat use the snmp/6 interface to collect interface statistics.

The kernel only zImage grows by about 5-9KB ? I would like to enable this by default for all 5.4 kernels, so i can use the new io_uring samba-4.12.x vfs module by default. The associated liburing was already submitted and merged. The kernel + liburing was tested on ARM/mvebu via samba4 vfs_io_uring module and i have no issues so far. Some extra reads on it and why we should enable it by default, since i expect more packages to use this in the future. https://wiki.samba.org/index.php/Samba_4.12_Features_added/changed#.27io_uring.27_vfs_module https://lwn.net/Articles/810414/ https://kernel.dk/io_uring.pdf https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.6-IO-uring-Tests Signed-off-by: Andy Walsh <andy.walsh44+github@gmail.com>
* build: Add IRQSOFF and PREEMPT TRACER kernel config optionHauke Mehrtens2020-12-161-0/+34
| | | | | | | | | | | | | This adds the CONFIG_IRQSOFF_TRACER and the CONFIG_PREEMPT_TRACER kernel configuration option to the OpenWrt menu. This can be used to debug latencies in the system. The CONFIG_PREEMPT_TRACER option needs the CONFIG_PREEMPT option which is supposed to be used for Low-Latency Desktop and not used by many targets in OpenWrt.

| | | | | | | | | | | | | Enable CONFIG_KEYS by default on systems which are not marked as flash-space constraint by the 'small_flash' feature. CONFIG_KEYS is required by Docker, enabling it in our kernel allows users to run Docker on stock OpenWrt.

* libcxx[abi]: removeRosen Penev2020-12-071-4/+0
| | | | | | | | | | | | This is a neat project, but offers no benefit to OpenWrt. The initial reason for it was to be a replacement for libstdcpp as it is smaller and lacks compatibility for C++98. Unfortunately, compiling several packages with it results in larger ipk sizes. While not a member of the packages feed, this will be moved to packages-abandoned to keep it somewhere.

Patch the original makefile in order to avoid building elftoc, since it fails with musl's elf.h. This is fine, since we only need sstrip anyway.

* config: add KERNEL_LSM symbolPaul Spooren2020-09-031-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LSM (Linux security mechanism) list is the successor of the now legacy *major LSM*. Instead of defining a single security mechanism the LSM symbol is a comma separated list of mechanisms to load. Until recently OpenWrt would only support DAC (Unix discretionary access controls) which don't require an additional entry in the LSM list. With the newly introduced SELinux support the LSM needs to be extended else only a manual modified Kernel cmdline (`security=selinux`) would activate SELinux. As the default OpenWrt Kernel config sets DAC as default security mechanism, SELinux is stripped from the LSM list, even if `KERNEL_DEFAULT_SECURITY_SELINUX` is activated. To allow SELinux without a modified cmdline this commit sets a specific LSM list if `KERNEL_SECURITY_SELINUX` is enabled. The upstream Kconfig adds even more mechanisms (smack,selinux,tomoyo,apparmor), but until they're ported to OpenWrt, these can be ignored. To compile SELinux Kernel support but disable it from loading, the already present options `KERNEL_SECURITY_SELINUX_DISABLE` or `KERNEL_SECURITY_SELINUX_BOOTPARAM` (with custom cmdline `selinux=0`) can be used. Further it's possible to edit `/etc/selinux/config`. Signed-off-by: Paul Spooren <mail@aparcar.org>

* rb532: drop targetAdrian Schmutzler2020-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This target is still on kernel 4.14, and recent attempts to move it to kernel 5.4 have not led to success. The device tester reported that it wouldn't boot with the following messages: From sysupgrade: Press any key within 4 seconds to enter setup.... loading kernel from nand... OK setting up elf image... OK jumping to kernel code At this point the system hangs. From CompactFlash: Press any key within 4 seconds to enter setup.... Booting CF Loading kernel... done setting up elf image... kernel out of range kernel loading failed The tester reported that the same was observed with current master (kernel 4.14) as well. This looks like some kernel size restriction. Since this target is quite old and only supports one device, and since nobody else seemed interested in working on this for quite some time, I decided to not put further work into analyzing the problem and drop this together with the other 4.14-only targets.

* build: make prefix mapping of debug information optionalFelix Fietkau2020-08-061-0/+9
| | | | | | | | | | | | | | Remapping the local build path in debug information makes debugging using ./scripts/remote-gdb harder, because files no longer refer to the full path on the build host. For local builds, debug information does not need to be reproducible, since it will be stripped out of packages anyway.

* build: refactor JSON info files to `profiles.json`Paul Spooren2020-04-031-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JSON info files contain machine readable information of built profiles and resulting images. These files were added in commit 881ed09ee6e2 ("build: create JSON files containing image info"). They are useful for firmware wizards and script checking for reproducibility. Currently all JSON files are stored next to the built images, resulting in up to 168 individual files for the ath79/generic target. This patch refactors the JSON creation to store individual per image (not per profile) files in $(BUILD_DIR)/json_info_files and create an single overview file called `profiles.json` in the target directory. Storing per image files and not per profile solves the problem of parallel file writes. If a profiles sysupgrade and factory image are finished at the same time both processes would write to the same JSON file, resulting in randomly broken outputs. Some target like x86/64 do not use the image code yet, resulting in missing JSON files. If no JSON info files were created, no `profiles.json` files is created as it would be empty anyway. As before, this creation is enabled by default only if `BUILDBOT` is set. Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.
