* Revert "wic: Add --embed-rootfs argument"Richard Purdie2020-04-074-31/+1
| | | | | | | | | This reverts commit efdcf94801f6abe8e4099e324d9a3deccd8d4384. After discussion on the mailing list it was felt these changes were not ready yet. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* dev-manual: use "git", not "apmd", to explain checksum namesrpjday@crashcourse.ca2020-04-061-8/+9
| | | | | | | | | | | The apmd recipe is no longer appropriate to demonstrate the use of SRC_URI checksum names as it has only a single SRC_URI URL, so pick a more illuminating recipe.

* dev-manual: use "strace" for PV example, not cdrtoolsrpjday@crashcourse.ca2020-04-061-4/+4
| | | | | | | | | | | | | | | | | | | | | Section 3.3.5, "Fetching Code", uses the cdrtools recipe as an example for showing the use of PV, but that's a bad example since the current cdrtools recipe file contains: SRC_URI = " \ ${SOURCEFORGE_MIRROR}/project/cdrtools/cdrtools-${REALPV}.tar.bz2 \ ... PV = "3.01a31+really3.01" REALPV = "3.01" which is not exactly the point the dev manual is trying to make, so replace with simpler strace recipe.

* bitbake: tinfoil: Add back ability to parse on top of a datastoreRichard Purdie2020-04-062-4/+6
| | | | | | | | | | | This option was removed recently as we didn't realise the layerindex relies upon it. Add back the API which it turns out can be supported as long as we assume the datastore passed in is a remote datastore which it usually would be unless created locally.

* bitbake: data/siggen: Don't expand ignored variablesRichard Purdie2020-04-063-4/+4
| | | | | | | | | | | | | | | | | | If a variable is in the signature whitelist, we'd currently expand it, then later ignore the data. This is problemtic for code which has effects when expanded, recently source date epoch in OE-Core for example. We don't actually need to do this, if we pass the whitelist into the earlier function it can avoid the expansion. This also also give a small performance boost since we avoid running code in some cases.

* apt-native: don't let dpkg overwrite files by defaultJan Luebbe2020-04-061-1/+1
| | | | | | | | | | | | | | | | | With --force-overwrite (implied by --force-all), dpkg will not abort when a package overwrites files from different packages. As this can also lead to "The following package disappeared from your system as all files have been overwritten by other packages: <package>" and subsequently broken dependencies, this makes the simple case of conflicting files hard to debug. Instead of finding all possibly required force options, only disable overwrite for now.

| | | | | | | | | | | | | | | | Currently, this unit is packaged into udev-hwdb which then adds it as rdep instead of rrecommends to systemd itself, this meant that even if we added udev-hwdb to BAD_RECOMMENDATIONS, it would not be respected since its a rdep, therefore move the service unit file into udev package instead, this decouples the hard runtime dependency and restores the bad recommendations expectations (From OE-Core rev: bfaaefe8346e9f0eab153981fe6a3cc63590afb5) Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Alex Kiernan <alex.kiernan@gmail.com> Cc: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* wic: Add --embed-rootfs argumentRicardo Ribalda Delgado2020-04-064-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | This option adds the content of a rootfs on a specific location on the rootfs. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --embed-rootfs target-image /export --embed-rootfs target-image2 /export2 on the .wks file.

* wic: Fix permissions when using exclude or include pathRicardo Ribalda Delgado2020-04-061-3/+19
| | | | | | | | | | | | | | | | | | | | | When parameters include_path or exclude_path are passed to the rootfs plugin, it will copy the partition content into a folder and make all the modifications there. This is done using copyhardlinktree(), which does not take into consideration the content of the pseudo folder, which contains the information about the right permissions and ownership of the folders. This results in a rootfs owned by the user that is running the wic command (usually UID 1000), which makes some rootfs unbootable. To fix this we copy the content of the pseudo folders to the new folder and modify the pseudo database using the "pseudo -B" command.

* pseudo: Force seccomp to return success when in fact doing nothingRichard Purdie2020-04-062-0/+125
| | | | | | | | | | | | | | Pseudo changes the syscall access patterns which makes it incompatible with seccomp. Therefore intercept the seccomp syscall and alter it, pretending that seccomp was setup when in fact we do nothing. If we error as unsupported, utilities like file will exit with errors so we can't just disable it. This works around issues on platforms where seccomp is enabled in file (e.g. archlinux).

WSLv2 is available on Windows 10 build number > 18917 The current build number may be checked by opening a cmd prompt on Windows and running: C:\Users\myuser>ver Microsoft Windows [Version 10.0.19041.113] If a distro has already been installed via the Microsoft Store, then we can check which WSL version its using by opening a Windows Powershell (notice this is a powershell and not a cmd prompt): C:\WINDOWS\system32> wsl -l -v NAME STATE VERSION * Ubuntu Running 2 Debian Stopped 1 In this case it shows two distros installed, Ubuntu running WSLv2 and Debian running WSLv1 To change the version of WSL being used by a certain distro run: C:\WINDOWS\system32> wsl --set-version <Distro> 2 e.g C:\WINDOWS\system32> wsl --set-version Debian 2 For more information on installing WSLv2 please look at: https://docs.microsoft.com/en-us/windows/wsl/wsl2-install There are some caveats related to the way storage is handled by WSLv2 though, and at this point these have to be managed by the user manually, the storage space used by WSL is not reflected immediately and since bitbake heavily uses storage, after several builds this can prove to be a bit of an issue. WSLv2 uses a VHDX file for storage, this issue can be easily avoided by optimizing this file every now and then, this can be done via the following: 1.- Find the location of your VHDX file: - Get the distro app package directory. - Open Windows Powershell as Administrator and run: Get-AppxPackage -Name "*<DISTRO>*" | Select PackageFamilyName e.g.: PS C:\WINDOWS\system32> Get-AppxPackage -Name "*Ubuntu*" | Select PackageFamilyName PackageFamilyName ----------------- CanonicalGroupLimited.UbuntuonWindows_79abcdefgh Replace the PackageFamilyName (and your user) on the following path: C:\Users\<user>\AppData\Local\Packages\<PackageFamilyName>\LocalState\ e.g. ls C:\Users\<user>\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79abcdefgh\LocalState\ Mode LastWriteTime Length Name -a---- 3/14/2020 9:52 PM 57418973184 ext4.vhdx The VHDX file path is: C:\Users\<user>\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79abcdefgh\LocalState\ext4.vhdx 2.- Optimize your VHDX file (Also on Powershell): - Make sure WSL is shutdown wsl --shutdown - Optimize it optimize-vhd -Path C:\Users\<user>\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79abcdefgh\LocalState\ext4.vhdx -Mode full A progress bar should be shown while optimizing the VHDX file. As an example, after building core-image-sato, removing the TMPDIR did not reflect any changes on Windows Explorer for storage space being used, after optimizing the VHDX file, 14 extra GB were shown as free. So, as long as the the user optimizes its storage, the builds should run smoothly. This patch warns the user that is running bitbake under WSLv2, that they should optimize the VHDX file eventually to avoid storage issues. The same check previoulsy used for WSLv1 works for WSLv2, checking for the kernel version: WSLv1: Linux version 4.4.0-19041-Microsoft (Microsoft@Microsoft.com) WSLv2: Linux version 4.19.84-microsoft-standard (oe-user@oe-host) Builds have been tested under Ubuntu and Debian distros offered and installed through the Microsoft Store, and other distros should be able to run builds just as fine. Performance wise, using the same hardware, and same configuration a comparison between builds using native Linux vs WSLv2 for the following targets has been performed: - core-image-minimal - core-image-sato - core-image-sato-sdk - meta-toolchain No real evidence of any performance changes could be found, with WSLv2 builds running even faster in some cases. Running a recently built image can be done just as smoothly, if using "nographic" as argument for runqemu, or if its a graphical image, installing an X server and running runqemu runs just as fine. Happy bitbaking.
