tests: introduce prctl_marker

2021-08-17T08:00:00+00:00

This helper invokes a prctl syscall with very specific arguments for use
as a marker.

* tests/prctl_marker.c: New file.
* tests/Makefile.am (libtests_a_SOURCES): Add prctl_marker.c.
* tests/tests.h (prctl_marker): New prototype.

tests/prctl-success.sh: match strace output with -a value more than 79

2021-08-17T02:00:53+00:00

For some tests it is instructive to set -a to value more than 79; the
issue is that this alignment width is more than the marker output, which
leads to a match failure.  To avoid that, allow for arbitrary number
of spaces before the syscall return value.

* tests/prctl-success.sh: Relax the regular expression to allow
for arbitrary (non-zero) number of spaces.

Complements: v5.13-49-g6f0be228b "tests/prctl.sh: match strace output with -a value more than 79"

tests/prctl.sh: match strace output with -a value more than 79

2021-08-14T18:44:45+00:00

For some tests it is instructive to set -a to value more than 79; the
issue is that this alignment width is more than the marker output, which
leads to a match failure.  To avoid that, allow for arbitrary number
of spaces before the syscall return value.

(non-zero) number of spaces.

tests: move scno tampering check to init.sh

2021-08-14T12:27:28+00:00

And convert it to a function.

* tests/init.sh (check_scno_tampering): New funtion, move the body
from...
* tests/scno_tampering.sh: ...here; call check_scno_tampering.

prctl: print PR_SET_PTRACER_ANY numerical value as int

2021-08-14T12:24:37+00:00

While it is declared as (unsigned long)-1, there's little sense to print
it as it is, since the comparison is ultimately done against arg2 casted
to int.

* src/prctl.c (SYS_FUNC(prctl)) : Cast arg2 to int
when passing to print_xlat_ex; use XLAT_STYLE_FMT_D style.

tests: convert prctl-fp-mode and prctl-spec-inject into generated tests

2021-08-14T01:27:44+00:00

And also avoid injecting values into prctl() calls issued by libc during
process startup.

* tests/Makefile.am (DECODER_TESTS): Remove prctl-fp-mode.test
and prctl-spec-inject.test.
* tests/gen_tests.in (prctl-fp-mode, prctl-spec-inject): New tests.
* tests/prctl-fp-mode.test: Remove.
* tests/prctl-spec-inject.test: Likewise.
* tests/prctl-fp-mode.c: Implement injected return value locking sequence.
* tests/prctl-spec-inject.c: Likewise.
