2021-07-06sandbox: Support signal handling only when requestedSimon Glass
At present if sandbox crashes it prints a message and tries to exit. But with the recently introduced signal handler, it often seems to get stuck in a loop until the stack overflows: Segmentation violation Segmentation violation Segmentation violation Segmentation violation Segmentation violation Segmentation violation Segmentation violation ... The signal handler is only useful for a few tests, as I understand it. Make it optional. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-07-05Azure: Add loop devices and CAP_SYS_ADMIN for sandbox test.py testsAlper Nebi Yasak
The filesystem test setup needs to prepare disk images for its tests, with either guestmount or loop mounts. The former requires access to the host fuse device (added in a previous patch), the latter requires access to host loop devices. Both mounts also need additional privileges since docker's default configuration prevents the containers from mounting filesystems (for host security). Add any available loop devices to the container and try to add as few privileges as possible to run these tests, which narrow down to adding SYS_ADMIN capability and disabling apparmor confinement. However, this much still seems to be insecure enough to let malicious container processes escape as root on the host system [1]. [1] https://blog.trailofbits.com/2019/07/19/understanding-docker-container-escapes/ Since the mentioned tests are marked to run only on the sandbox board, add these additional devices and privileges only when testing with that. An alternative to using mounts is modifying the filesystem tests to use virt-make-fs (like some EFI tests do), but it fails to generate a partitionless FAT filesystem image on Debian systems. Other more feasible alternatives are using guestfish or directly using libguestfs Python bindings to create and populate the images, but switching the test setups to these is nontrivial and is left as future work.

2021-07-05tools: docker: Install a readable kernel for libguestfs-toolsAlper Nebi Yasak
The filesystem and EFI (capsule and secure boot) test setups try to use guestmount and virt-make-fs respectively to prepare disk images to run tests on. However, these libguestfs tools need a kernel image and fail with the following message (revealed in debug/trace mode) if it can't find one: supermin: failed to find a suitable kernel (host_cpu=x86_64). I looked for kernels in /boot and modules in /lib/modules. If this is a Xen guest, and you only have Xen domU kernels installed, try installing a fullvirt kernel (only for supermin use, you shouldn't boot the Xen guest with it). This failure then causes these tests to be skipped in CIs. Install a kernel package in the Docker containers so the CIs can run these tests with libguestfs tools again (assuming the container is run with necessary host devices and privileges). As this kernel would be only used for virtualization, we can use the kernel package specialized for that. On Ubuntu systems kernel images are not readable by non-root users, so explicitly add read permissions with chmod as well.

2021-07-05test/py: Wait for guestmount worker to exit after running guestunmountAlper Nebi Yasak
Some filesystem tests are failing when their image is prepared with guestmount, but succeeding if loop mounts are used instead. The reason seems to be a race condition the guestmount(1) manual page explains: When guestunmount(1)/fusermount(1) exits, guestmount may still be running and cleaning up the mountpoint. The disk image will not be fully finalized. This means that scripts like the following have a nasty race condition: guestmount -a disk.img -i /mnt # copy things into /mnt guestunmount /mnt # immediately try to use 'disk.img' ** UNSAFE ** The solution is to use the --pid-file option to write the guestmount PID to a file, then after guestunmount spin waiting for this PID to exit. The Python standard library has an os.waitpid() function for waiting a child to terminate, but it cannot wait on non-child processes. Implement a utility function that can do this by polling the process repeatedly for a given duration, optionally killing the process if it won't terminate on its own. Apply the suggested solution with this utility function, which makes the failing tests succeed again.

2021-07-05test/py: Use loop mounts if guestmount fails in filesystem testsAlper Nebi Yasak
If guestmount isn't available on the system, filesystem test setup falls back to using loop mounts to prepare its disk images. If guestmount is available but fails to work, the tests are immediately skipped. Instead of giving up on a guestmount failure, try using loop mounts as an attempt to keep tests running. Also stop checking if guestmount is in PATH, as trying to run a missing guestmount can now follow the same failure codepath and fall back to loop mounts anyway.

2021-07-02efi_loader: Allow capsule update on-disk without checking OsIndicationsIlias Apalodimas
Although U-Boot supports capsule update on-disk, it's lack of support for SetVariable at runtime prevents applications like fwupd from using it. In order to perform the capsule update on-disk the spec says that the OS must copy the capsule to the \EFI\UpdateCapsule directory and set a bit in the OsIndications variable. The firmware then checks for the EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED bit in OsIndications variable, which is set by the submitter to trigger processing of the capsule on the next reboot. Let's add a config option which ignores the bit and just relies on the capsule being present. Since U-Boot deletes the capsule while processing it, we won't end up applying it multiple times. Note that this is allowed for all capsules. In the future, once authenticated capsules are fully supported, we can limit the functionality to those only.

Chapter 23 of the EFI spec (rev 2.9) says: "A specific updatable hardware firmware store must be represented by exactly one FMP instance". This is not the case for us, since both of our FMP protocols can be installed at the same time because they are controlled by a single 'dfu_alt_info' env variable. So make the config options depend on each other and allow the user to install one of them at any given time. If we fix the meta-data provided by the 'dfu_alt_info' in the future, to hint about the capsule type (fit or raw) we can revise this and enable both FMPs to be installed, as long as they target different firmware hardware stores Note that we are not using a Kconfig 'choice' on purpose, since we want to allow both of those to be installed and tested in sandbox Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2021-07-01Merge branch '2021-07-01-buildtime-gd-sanity-check' into nextTom Rini
- Merge build-time sanity checks to ensure the size of gd doesn't change. This can happen during cleanups due to not all symbols being implemented in Kconfig.
2021-07-01global-data.h: add build-time sanity check of sizeof(struct global_data)Rasmus Villemoes
The layout and contents of struct global_data depends on a lot of CONFIG_* preprocessor macros, not all of which are entirely converted to Kconfig - not to mention weird games played here and there. This can result in one translation unit using one definition of struct global_data while the actual layout is another. That can be very hard to debug. But we already have a mechanism that can help catch such bugs at build time, namely the asm-offsets machinery which is necessary anyway to provide assembly code with the necessary constants. So make sure that every C translation unit that include global_data.h actually sees the same size of struct global_data as that which was seen by the asm-offsets.c TU. It is likely that this patch will break the build of some boards. For example, without the patch from Matt Merhar (https://lists.denx.de/pipermail/u-boot/2021-May/450135.html) or some other fix, this breaks P2041RDB_defconfig: CC arch/powerpc/lib/traps.o AS arch/powerpc/cpu/mpc85xx/start.o In file included from include/asm-generic/global_data.h:26, from ./arch/powerpc/include/asm/global_data.h:109, from include/init.h:21, from arch/powerpc/lib/traps.c:7: include/linux/build_bug.h:99:41: error: static assertion failed: "sizeof(struct global_data) == GD_SIZE" 99 | #define __static_assert(expr, msg, ...) _Static_assert(expr, msg) | ^~~~~~~~~~~~~~ include/linux/build_bug.h:98:34: note: in expansion of macro ‘__static_assert’ 98 | #define static_assert(expr, ...) __static_assert(expr, ##__VA_ARGS__, #expr) | ^~~~~~~~~~~~~~~ include/asm-generic/global_data.h:470:1: note: in expansion of macro ‘static_assert’ 470 | static_assert(sizeof(struct global_data) == GD_SIZE); | ^~~~~~~~~~~~~ make[1]: *** [scripts/Makefile.build:266: arch/powerpc/lib/traps.o] Error 1 make: *** [Makefile:1753: arch/powerpc/lib] Error 2 make: *** Waiting for unfinished jobs....

2021-07-01build_bug.h: add wrapper for _Static_assertRasmus Villemoes
[Linux commit 6bab69c65013bed5fce9f101a64a84d0385b3946] BUILD_BUG_ON() is a little annoying, since it cannot be used outside function scope. So one cannot put assertions about the sizeof() a struct next to the struct definition, but has to hide that in some more or less arbitrary function. Since gcc 4.6 (which is now also the required minimum), there is support for the C11 _Static_assert in all C modes, including gnu89. So add a simple wrapper for that. _Static_assert() requires a message argument, which is usually quite redundant (and I believe that bug got fixed at least in newer C++ standards), but we can easily work around that with a little macro magic, making it optional. For example, adding static_assert(sizeof(struct printf_spec) == 8); in vsprintf.c and modifying that struct to violate it, one gets ./include/linux/build_bug.h:78:41: error: static assertion failed: "sizeof(struct printf_spec) == 8" #define __static_assert(expr, msg, ...) _Static_assert(expr, "" msg "") godbolt.org suggests that _Static_assert() has been support by clang since at least 3.0.0.
