The change was made by the following commit of libcap: commit 177cd418031b1acfcf73fe3b1af9f3279828681c Author: Andrew G. Morgan Date: Tue Jul 21 22:58:05 2020 -0700 A more compact form for the text representation of capabilities. While this does not change anything about the supported range of equivalent text specifications for capabilities, as accepted by cap_from_text(), this does alter the preferred output format of cap_to_text() to be two characters shorter in most cases. That is, what used to be summarized as: "= cap_foo+..." is now converted to the equivalent text: "cap_foo=..." which is also more intuitive. So add a filter to change the old format to the new one, an helper that calls getcap with that filter, make existing tests use the new helper and update their golden output to match the new output format of getcap. Signed-off-by: Filipe Manana --- V2: Added _getcap() helper that makes use of the filter, make tests use it. common/filter | 28 ++++++++++++++++++++++++++++ common/rc | 6 ++++++ tests/btrfs/214 | 16 ++++++++-------- tests/generic/093 | 4 ++-- tests/generic/093.out | 2 +- tests/generic/513 | 4 ++-- tests/overlay/064 | 4 ++-- tests/overlay/064.out | 4 ++-- tests/xfs/296 | 4 ++-- tests/xfs/296.out | 4 ++-- 10 files changed, 55 insertions(+), 21 deletions(-) diff --git a/common/filter b/common/filter index 2477f386..a8b3882f 100644 --- a/common/filter +++ b/common/filter @@ -603,5 +603,33 @@ _filter_assert_dmesg() -e "s#$warn2#Intentional warnings in assfail#" } +# With version 2.41 of libcap, the output format of getcap changed. +# More specifically such change was added by the following commit: +# +# commit 177cd418031b1acfcf73fe3b1af9f3279828681c +# Author: Andrew G.
