* cmake: Disable use of package registriesJeffery To2020-08-241-0/+12
| | | | | | | | | | | | | | | | | CMake provides a user package registry (stored in ~/.cmake/packages) and a system package registry (not available on non-Windows platforms). The "export(PACKAGE)" command may store information in the user package registry, and the "find_package()" command may search both user and system package registries for information. This sets various variables to disable the use of these package registries (both saving and retrieval of package information). This also sets deprecated variables that perform similar functions, in case external toolchains include older versions of CMake. Signed-off-by: Jeffery To <jeffery.to@gmail.com>

* build: improve message for incompatible image on "legacy" devicesAdrian Schmutzler2020-08-081-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported that the current message displayed during upgrade with compat_version change is misleading for "legacy" devices, i.e. those without the "new" fwtool. This is partially caused by the fact that we need to exploit the supported_devices string to get some message text displayed for these devices. This patch modifies the message to make it more helpful and include additional information, e.g. Device linksys,wrt3200acm not supported by this image Supported devices: linksys,wrt3200acm linksys-whateverelse - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA Note that the line breaks (except the one before Supported devices) are added manually here, I hesitate to hack \n into the supported_devices as well. The "Reason:" will only be displayed if DEVICE_COMPAT_MESSAGE is set for the device, otherwise "Please check documentation ..." will be shown instead. While at it, also rearrange the code in image-commands.mk to make lines shorter and remove the double filter-out command. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* build: image: drop unused check-kernel-size recipeAdrian Schmutzler2020-08-021-7/+0
| | | | | | | | | | The recipe check-kernel-size is not used in the entire tree.

* base-files: fwtool: make compat_version backward compatibleAdrian Schmutzler2020-07-311-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, the compatibility mechanism only works if both device and image are already updated to the new routines. This patch extends the sysupgrade metadata and fwtool_check_image() to account for "older" images as well: The basic mechanism for older devices to check for image compatibility is the supported_devices entry. This can be exploited by putting a custom message into this variable of the metadata, so older FW will produce a mismatch and print the message as it thinks it's the list of supported devices. So, we have two cases: device 1.0, image 1.0: The metadata will just contain supported_devices as before. device 1.0, image 1.1: The metadata will contain: "new_supported_devices":["device_string1", "device_string2", ...], "supported_devices":["Image version 1.1 incompatible to device: ..."] If the device is "legacy", i.e. does not have the updated fwtool.sh, it will just fail with image check and print the content of supported_devices. If DEVICE_COMPAT_MESSAGE is set, this will be printed on old devices as well through the same mechanism. Otherwise a generic "Please check documentation ..." is appended. Upgrade can still be performed with -F like when SUPPORTED_DEVICES has been removed to prevent bricking. If the device has updated fwtool.sh (but is 1.0), it will just use the new_supported_devices instead, and work as intended (flashing with -n will work, flashing without will print the appropriate warning). This mechanism should provide a fair tradeoff between simplicity and functionality. Since we touched a lot of fields in metadata, this also bumps metadata_version to 1.1.

* build: add DEVICE_COMPAT_VERSION and DEVICE_COMPAT_MESSAGEAdrian Schmutzler2020-07-312-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We regularly encounter the situation that devices are subject to changes that will make them incompatible to previous versions. Removing SUPPORTED_DEVICES will not really be helpful in most of these cases, as this only helps after a rename. To solve this situation, this patchset introduces a compatibility version for devices. It will be implemented via a per-device Make variable DEVICE_COMPAT_VERSION, which will be set to 1.0 globally by default and then can be overwritten as needed. Furthermore, a variable DEVICE_COMPAT_MESSAGE is added, where a message to be displayed during sysupgrade may be specified optionally. This patch only implements the build variables and adds them to the sysupgrade metadata, the evaluation will be addressed in a subsequent patch. To set it, one would just need to add the following to a device node: define Device/somedevice ... DEVICE_COMPAT_VERSION := 1.1 DEVICE_COMPAT_MESSAGE := Config cannot be migrated from swconfig to DSA endef Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* build: add option to mark devices as BROKENAdrian Schmutzler2020-07-301-0/+2
| | | | | | | | | | | By specifying "BROKEN := 1" or "BROKEN := y" for a device, it will be hidden (and deselected) by default. By that, it provides a stronger option to "disable" a device beyond just using DEFAULT := n. To make these devices visible, just enable the BROKEN option in developer settings as already implemented for targets and packages. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* build: reduce number of files passed to ipk-removeEneas U de Queiroz2020-07-111-11/+8
| | | | | | | | | | | | | | | | | | | | Instead of using xargs to pass a huge number of files to script/ipkg-remove, which will usually pick only one, use a more restrictive wildcard so that, currently, at the most 325 files are examined, instead of up to over 2,300. The 325-file package is python, which is picking up python3* ipks. It is about to be removed. Runner-up is ddns-scripts with 7 files. This makes a second run of make package/luci/compile go from real 16.40s; user 17.42s; sys 2.73s to real 10.71s; user 9.51s; sys 1.27s There is a caveat though: if one were to remove the ABI_VERSION of a package that ends in a digit [0-9], then the old package ipk will not be removed from the bin directory by make package/abc2/clean.

* build: call ipkg-remove using xargs if #args>=512Eneas U de Queiroz2020-07-111-1/+11
| | | | | | | | | | | | | The wildcard call to clean up luci package (luci*) can pick up over 2,300 files when the full tree is built. Running make package/luci/clean or a second run of make package/luci/compile would fail with an 'Argument list too long' error. To avoid that, a maybe_use_xargs function was created that runs the command straight as usual if the number of arguments is < 512, or saves the list in a temporary file and feeds it to xargs otherwise.

* treewide: provide consistent basic DEVICE_TYPEAdrian Schmutzler2020-06-031-1/+2
| | | | | | | | | | | | | | | | | | | | | While the effective "default" based on frequent use is "router", the DEVICE_TYPE variable actually provides a "basic" configuration without selecting any additional packages. This is currently set up with the identifier "bootloader", which seems to be not used at all. However, the only targets not using "router" or "nas" are actually archs38 and arc770, which use their own value "developerboard" for DEVICE_TYPE which seems to have been invented when these targets where added. The latter is not implemented in target.mk, though, and will fall back to the "basic" set of packages then. So, to clean this up and make it more readable, let's just define a DEVICE_TYPE "basic" and use it for the aforementioned cases.

I made the following measurements for the most common compression tools (all standard Debian Buster versions, default flags unless noted otherwise), using the debug information of a large x86-64 kernel with ALL_KMODS: * kernel-debug.tar: 376M * kernel-debug.tar.gz: 101M, compressed in ~12s * kernel-debug.tar.bz2: 91M, compressed in ~15s * kernel-debug.tar.xz: 57M, compressed in ~101s * kernel-debug.tar.zst: 86M, compressed in ~1s With zstd, there is still some room for improvement by increasing the compression, but the slight increase in compression ratio (22.83% -> 19.46%) does not justify the significant increase in compression time (about 5 times on my machine) in my opinion. Note that multithreaded compression (-T argument) does not affect reproducibility with zstd. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>

* build: add option to treat recursive deps as errorEneas U de Queiroz2020-05-201-5/+8
| | | | | | | | Running make with RECURSIVE_DEP_IS_ERROR=1 will cause a hard failure when a recursive dependency is detected. This is useful to apply stricter Ci tests, for example. Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
