2022-07-10tools/testing/cxl: Move cxl_test resources to the top of memoryDan Williams
A recent QEMU upgrade resulted in collisions between QEMU's chosen location for PCI MMIO and cxl_test's fake address location for emulated CXL purposes. This was great for testing resource collisions, but not so great for continuing to test the nominal cases. Move cxl_test to the top-of-memory where it is less likely to collide with other resources.

2022-07-09cxl/mem: Convert partition-info to resourcesDan Williams
To date the per-device-partition DPA range information has only been used for enumeration purposes. In preparation for allocating regions from available DPA capacity, convert those ranges into DPA-type resource trees. With resources and the new add_dpa_res() helper some open coded end address calculations and debug prints can be cleaned. The 'cxlds->pmem_res' and 'cxlds->ram_res' resources are child resources of the total-device DPA space and they in turn will host DPA allocations from cxl_endpoint_decoder instances (tracked by cxled->dpa_res).

The mentioned test measures the transfer run-time to verify that the user-space program is able to use the full aggregate B/W. Even on (virtual) link-speed-bound tests, debug kernel can slow down the transfer enough to cause sporadic test failures. Instead of unconditionally raising the maximum allowed run-time, tweak when the running kernel is a debug one, and use some simple/ rough heuristic to guess such scenarios. Note: this intentionally avoids looking for /boot/config-<version> as the latter file is not always available in our reference CI environments.

2022-07-09x86/speculation: Disable RRSBA behaviorPawan Gupta
Some Intel processors may use alternate predictors for RETs on RSB-underflow. This condition may be vulnerable to Branch History Injection (BHI) and intramode-BTI. Kernel earlier added spectre_v2 mitigation modes (eIBRS+Retpolines, eIBRS+LFENCE, Retpolines) which protect indirect CALLs and JMPs against such attacks. However, on RSB-underflow, RET target prediction may fallback to alternate predictors. As a result, RET's predicted target may get influenced by branch history. A new MSR_IA32_SPEC_CTRL bit (RRSBA_DIS_S) controls this fallback behavior when in kernel mode. When set, RETs will not take predictions from alternate predictors, hence mitigating RETs as well. Support for this is enumerated by CPUID.7.2.EDX[RRSBA_CTRL] (bit2). For spectre v2 mitigation, when a user selects a mitigation that protects indirect CALLs and JMPs against BHI and intramode-BTI, set RRSBA_DIS_S also to protect RETs for RSB-underflow case.

This change addresses a comment made earlier [0] about a missing return of an error when __bpf_core_types_match is invoked from bpf_core_composites_match, which could have let to us erroneously ignoring errors. Regarding the typedef name check pointed out in the same context, it is not actually an issue, because callers of the function perform a name check for the root type anyway. To make that more obvious, let's add comments to the function (similar to what we have for bpf_core_types_are_compat, which is called in pretty much the same context).

2022-07-08kunit: tool: Enable virtio/PCI by default on UMLDavid Gow
There are several tests which depend on PCI, and hence need a bunch of extra options to run under UML. This makes it awkward to give configuration instructions (whether in documentation, or as part of a .kunitconfig file), as two separate, incompatible sets of config options are required for UML and "most other architectures". For non-UML architectures, it's possible to add default kconfig options via the qemu_config python files, but there's no equivalent for UML. Add a new tools/testing/kunit/configs/arch_uml.config file containing extra kconfig options to use on UML.

2022-07-08kunit: tool: make --kunitconfig repeatable, blindly concatDaniel Latypov
It's come up a few times that it would be useful to have --kunitconfig be repeatable [1][2]. This could be done before with a bit of shell-fu, e.g. $ find fs/ -name '.kunitconfig' -exec cat {} + | \ ./tools/testing/kunit/kunit.py run --kunitconfig=/dev/stdin or equivalently: $ cat fs/ext4/.kunitconfig fs/fat/.kunitconfig | \ ./tools/testing/kunit/kunit.py run --kunitconfig=/dev/stdin But this can be fairly clunky to use in practice. And having explicit support in kunit.py opens the door to having more config fragments of interest, e.g. options for PCI on UML [1], UML coverage [2], variants of tests [3]. There's another argument to be made that users can just use multiple --kconfig_add's, but this gets very clunky very fast (e.g. [2]). Note: there's a big caveat here that some kconfig options might be incompatible. We try to give a clearish error message in the simple case where the same option appears multiple times with conflicting values, but more subtle ones (e.g. mutually exclusive options) will be potentially very confusing for the user. I don't know we can do better. Note 2: if you want to combine a --kunitconfig with the default, you either have to do to specify the current build_dir > --kunitconfig=.kunit --kunitconfig=additional.config or > --kunitconfig=tools/testing/kunit/configs/default.config --kunitconifg=additional.config each of which have their downsides (former depends on --build_dir, doesn't work if you don't have a .kunitconfig yet), etc. Example with conflicting values: > $ ./tools/testing/kunit/kunit.py config --kunitconfig=lib/kunit --kunitconfig=/dev/stdin <<EOF > CONFIG_KUNIT_TEST=n > CONFIG_KUNIT=m > EOF > ... > kunit_kernel.ConfigError: Multiple values specified for 2 options in kunitconfig: > CONFIG_KUNIT=y > vs from /dev/stdin > CONFIG_KUNIT=m > > CONFIG_KUNIT_TEST=y > vs from /dev/stdin > # CONFIG_KUNIT_TEST is not set [1] https://lists.freedesktop.org/archives/dri-devel/2022-June/357616.html [2] https://lore.kernel.org/linux-kselftest/CAFd5g45f3X3xF2vz2BkTHRqOC4uW6GZxtUUMaP5mwwbK8uNVtA@mail.gmail.com/ [3] https://lore.kernel.org/linux-kselftest/CANpmjNOdSy6DuO6CYZ4UxhGxqhjzx4tn0sJMbRqo2xRFv9kX6Q@mail.gmail.com/ Signed-off-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

Commit 13bbbfbea759 ("bpf: Add bpf_dynptr_read and bpf_dynptr_write") added the bpf_dynptr_write() and bpf_dynptr_read() APIs. However, it will be needed for some dynptr types to pass in flags as well (e.g. when writing to a skb, the user may like to invalidate the hash or recompute the checksum). This patch adds a "u64 flags" arg to the bpf_dynptr_read() and bpf_dynptr_write() APIs before their UAPI signature freezes where we then cannot change them anymore with a 5.19.x released kernel.

2022-07-07kunit: tool: refactor internal kconfig handling, allow overridingDaniel Latypov
Currently, you cannot ovewrwrite what's in your kunitconfig via --kconfig_add. Nor can you override something in a qemu_config via either means. This patch makes it so we have this level of priority * --kconfig_add * kunitconfig file (the default or the one from --kunitconfig) * qemu_config The rationale for this order is that the more "dynamic" sources of kconfig options should take priority. --kconfig_add is obviously the most dynamic. And for kunitconfig, users probably tweak the file manually or specify --kunitconfig more often than they delve into qemu_config python files. And internally, we convert the kconfigs from a python list into a set or dict fairly often. We should just use a dict internally. We exposed the set transform in the past since we didn't define __eq__, so also take the chance to shore up the kunit_kconfig.Kconfig interface. Example ======= Let's consider the unrealistic example where someone would want to disable CONFIG_KUNIT. I.e. they run $ ./tools/testing/kunit/kunit.py config --kconfig_add=CONFIG_KUNIT=n Before ------ We'd write the following > # CONFIG_KUNIT is not set > CONFIG_KUNIT_ALL_TESTS=y > CONFIG_KUNIT_TEST=y > CONFIG_KUNIT=y > CONFIG_KUNIT_EXAMPLE_TEST=y And we'd error out with > ERROR:root:Not all Kconfig options selected in kunitconfig were in the generated .config. > This is probably due to unsatisfied dependencies. > Missing: # CONFIG_KUNIT is not set After ----- We'd write the following > # CONFIG_KUNIT is not set > CONFIG_KUNIT_TEST=y > CONFIG_KUNIT_ALL_TESTS=y > CONFIG_KUNIT_EXAMPLE_TEST=y And we'd error out with > ERROR:root:Not all Kconfig options selected in kunitconfig were in the generated .config. > This is probably due to unsatisfied dependencies. > Missing: CONFIG_KUNIT_EXAMPLE_TEST=y, CONFIG_KUNIT_TEST=y, CONFIG_KUNIT_ALL_TESTS=y Signed-off-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: David Gow <davidgow@google.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

For consistency with --kernel_args, we allow users to repeat this argument, e.g. you can tack on a --qemu_args='-m 2048', or you could just append it to the first string ('-smp 8 -m 2048').

2022-07-07kunit: tool: cosmetic: don't specify duplicate kernel cmdline optionsDaniel Latypov
Context: When using a non-UML arch, kunit.py will boot the test kernel with options like these by default (this is x86_64): > mem=1G console=tty kunit_shutdown=halt console=ttyS0 kunit_shutdown=reboot The first three options are added unconditionally but are only intended for UML. 1. 'mem=1G' is redundant with the '-m 1024' that we hard-code into the qemu commandline. 2. We specify a 'console' for all tools/testing/kunit/qemu_configs/*.py already, so 'console=tty' gets overwritten. 3. For QEMU, we need to use 'reboot', and for UML we need to use 'halt'. If you switch them, kunit.py will hang until the --timeout expires. This patch: Having these duplicate options is a bit noisy. Switch so we only add UML-specific options for UML. I.e. we now get UML: 'mem=1G console=tty kunit_shutdown=halt' (unchanged) x86_64: 'console=ttyS0 kunit_shutdown=reboot' Side effect: you can't overwrite these options on UML w/ --kernel_arg. But you already couldn't for QEMU (console, kunit_shutdown), and why would you want to?

2022-07-07selftests/sgx: Test reclaiming of untouched pageReinette Chatre
Removing a page from an initialized enclave involves three steps: (1) the user requests changing the page type to PT_TRIM via the SGX_IOC_ENCLAVE_MODIFY_TYPES ioctl() (2) on success the ENCLU[EACCEPT] instruction is run from within the enclave to accept the page removal (3) the user initiates the actual removal of the page via the SGX_IOC_ENCLAVE_REMOVE_PAGES ioctl(). Remove a page that has never been accessed. This means that when the first ioctl() requesting page removal arrives, there will be no page table entry, yet a valid page table entry needs to exist for the ENCLU[EACCEPT] function to succeed. In this test it is verified that a page table entry can still be installed for a page that is in the process of being removed.

The expected behavior is a page fault with the SGX flag set in the error code. * Test the behavior when the page type is changed successfully and ENCLU[EACCEPT] was run from within the enclave. The final ioctl(), SGX_IOC_ENCLAVE_REMOVE_PAGES, is omitted and replaced with an attempt to access the page.

2022-07-07selftests/sgx: Test complete changing of page type flowReinette Chatre
Support for changing an enclave page's type enables an initialized enclave to be expanded with support for more threads by changing the type of a regular enclave page to that of a Thread Control Structure (TCS). Additionally, being able to change a TCS or regular enclave page's type to be trimmed (SGX_PAGE_TYPE_TRIM) initiates the removal of the page from the enclave. Test changing page type to TCS as well as page removal flows in two phases: In the first phase support for a new thread is dynamically added to an initialized enclave and in the second phase the pages associated with the new thread are removed from the enclave. As an additional sanity check after the second phase the page used as a TCS page during the first phase is added back as a regular page and ensured that it can be written to (which is not possible if it was a TCS page).

2022-07-07selftests/sgx: Introduce dynamic entry pointReinette Chatre
The test enclave (test_encl.elf) is built with two initialized Thread Control Structures (TCS) included in the binary. Both TCS are initialized with the same entry point, encl_entry, that correctly computes the absolute address of the stack based on the stack of each TCS that is also built into the binary. A new TCS can be added dynamically to the enclave and requires to be initialized with an entry point used to enter the enclave. Since the existing entry point, encl_entry, assumes that the TCS and its stack exists at particular offsets within the binary it is not able to handle a dynamically added TCS and its stack. Introduce a new entry point, encl_dyn_entry, that initializes the absolute address of that thread's stack to the address immediately preceding the TCS itself. It is now possible to dynamically add a contiguous memory region to the enclave with the new stack preceding the new TCS. With the new TCS initialized with encl_dyn_entry as entry point the absolute address of the stack is computed correctly on entry.

2022-07-07selftests/sgx: Test two different SGX2 EAUG flowsReinette Chatre
Enclave pages can be added to an initialized enclave when an address belonging to the enclave but without a backing page is accessed from within the enclave. Accessing memory without a backing enclave page from within an enclave can be in different ways: 1) Pre-emptively run ENCLU[EACCEPT]. Since the addition of a page always needs to be accepted by the enclave via ENCLU[EACCEPT] this flow is efficient since the first execution of ENCLU[EACCEPT] triggers the addition of the page and when execution returns to the same instruction the second execution would be successful as an acceptance of the page. 2) A direct read or write. The flow where a direct read or write triggers the page addition execution cannot resume from the instruction (read/write) that triggered the fault but instead the enclave needs to be entered at a different entry point to run needed ENCLU[EACCEPT] before execution can return to the original entry point and the read/write instruction that faulted.

EPCM permission changes could be made from within (to relax permissions) or out (to restrict permissions) the enclave. Kernel support is needed when permissions are restricted to be able to call the privileged ENCLS[EMODPR] instruction. EPCM permissions can be relaxed via ENCLU[EMODPE] from within the enclave but the enclave still depends on the kernel to install PTEs with the needed permissions. Add a test that exercises a few of the enclave page permission flows: 1) Test starts with a RW (from enclave and kernel perspective) enclave page that is mapped via a RW VMA. 2) Use the SGX_IOC_ENCLAVE_RESTRICT_PERMISSIONS ioctl() to restrict the enclave (EPCM) page permissions to read-only. 3) Run ENCLU[EACCEPT] from within the enclave to accept the new page permissions. 4) Attempt to write to the enclave page from within the enclave - this should fail with a page fault on the EPCM permissions since the page table entry continues to allow RW access. 5) Restore EPCM permissions to RW by running ENCLU[EMODPE] from within the enclave. 6) Attempt to write to the enclave page from within the enclave - this should succeed since both EPCM and PTE permissions allow this access.
