[PATCH v6] runtest: Add skip files for Morello

by Teo Couprie Diaz

Add a set of skip files for running the syscalls set of tests in compat or purecap: - syscalls_morello_musl_skip skips all Musl related failures, - syscalls_morello_skip is for tests skipped and not built for Morello, - syscalls_morello_purecap_skip is for tests skipped in purecap. Update the README to reflect those additions and explain how to use the skip files. This is preparation for CI testing in Morello release 1.6 and later. Signed-off-by: Teo Couprie Diaz <teo.coupriediaz(a)arm.com> --- v6: - Clarified wording on build setup and version compatibility - Added two missing tests to the relevant skip lists v5: - Clarified the wording around syscalls_morello_skip thanks to Kevin's comments. - Added command line example for purecap skip files. v4: - Some README rephrasing to address Beata's comments - Changed kernel version dependency comment in the musl skip file - Renamed all skip files to accomodate for a purecap one - Added purecap skip file - Updated README and commit message for purecap skip file v3: - Added *_16 tests to the skip list - Added tests from kernel/security as we don't build them yet - Mentioned Morello 1.6 release v2: - Removed mentions of COMPAT - Reworded comment around Alpine - Added bpf_prog02 to the musl skips after further testing README.rst | 30 +++++ runtest/syscalls_morello_musl_skip | 18 +++ runtest/syscalls_morello_purecap_skip | 12 ++ runtest/syscalls_morello_skip | 173 ++++++++++++++++++++++++++ 4 files changed, 233 insertions(+) create mode 100644 runtest/syscalls_morello_musl_skip create mode 100644 runtest/syscalls_morello_purecap_skip create mode 100644 runtest/syscalls_morello_skip diff --git a/README.rst b/README.rst index 8b6e3a7769d0..e8293e24401d 100644 --- a/README.rst +++ b/README.rst @@ -136,6 +136,36 @@ Running tests: runltp -f morello_transitional,morello_transitional_extended +Skipping tests: +--------------- + +In certain cases, you might want to skip tests that are known to be failing or are yet to be supported. + +This is done by passing a file containing the names of the tests to be skip with the option ``-S`` to +``runltp``. + +We currently provide the following skip files under ``runtest/``: + - ``syscalls_morello_musl_skip``: Skips all tests failing on a regular AArch64 Musl based system. + - ``syscalls_morello_skip``: Skips all tests not considered due to the Morello build setup, + or the run environment. + - ``syscalls_morello_purecap_skip``: Skips all tests not considered while testing with purecap binaries. + +``runltp`` does not support passing multiple skip files, however this can be circumvented by using +process substitution. + +.. code-block:: + + ./runltp -f syscalls -S <( cat runtest/syscalls_morello{,_musl}_skip ) + +To use all relevant skip files relevant for plain AArch64. + +.. code-block:: + + ./runltp -f syscalls -S <( cat runtest/syscalls_morello{,_musl,_purecap}_skip ) + +To use all relevant skip files relevant for pure-capability. + +These skip files are comprehensive only for morello release 1.6 and above.

[PATCH v2] syscalls/sockioctl: Align buffer to struct ifreq

by Teo Couprie Diaz

In setup3, the following line can lead to an undefined behavior: ifr = *(struct ifreq *)ifc.ifc_buf; Indeed, at this point it can be assumed that ifc.ifc_buf is suitably aligned for struct ifreq. However, ifc.ifc_buf is assigned to buf which has no alignment constraints. This means there exists cases where buf is not suitably aligned to load a struct ifreq, which can generate a SIGBUS. This is exacerbated in purecap because of the increased alignment constraint of struct ifreq. Force the alignment of buf to that of struct ifreq. Signed-off-by: Teo Couprie Diaz <teo.coupriediaz(a)arm.com> --- The line mentionning purecap will be dropped when upstreaming. v2: - Use struct ifreq directly for alignment - Reformulate comments and commit message as the undefined behavior is not spectific to purecap - Change the attribute definition to be closer to more similar to the rest of the codebase.

Update the Makefiles for _16 and _64 tests in order to add them automatically to the Morello skip file if they aren't built.

[PATCH v3] runtest: Add skip files for compat

Add two skip files for running the syscalls set of tests in compat. One skips the tests failing because of Musl, the second the tests that we skip or don't build at all.

[PATCH v2] runtest: Add skip files for compat

by Teo Couprie Diaz

Add two skip files for running the syscalls set of tests in compat. One skips the tests failing because of Musl, the second the tests that we skip or don't build at all. Update the README to reflect those additions and explain how to use the skip files.
