[PATCH v3 0/4] xfstests: random fixes

[Andrey Albershteyn]

Hi folks,

This series contain a few random fixes I apply for xfstests in my
immutable test machines. These make it easier to work with read-only
xfstests package.

Changes from v2:
- Remove .out.good before running the test
- Fix "diff ..." message for tests with .out.good
Changes from v1:
- Add RvB
- Add comment in generic/452

Andrey Albershteyn (4):
  xfs/071: use _link_out_link instead of opencoding file picking
  common: link .out file to the output directory
  generic/452: make coping work with multi-call binary
  xfstests: fix permissions on system file installed by libtoolize

[PATCH v3 1/4] xfs/071: use _link_out_link instead of opencoding file picking

[Andrey Albershteyn]

There's function which handles picking the right output file based on
the .cfg.

[PATCH v3 2/4] common: link .out file to the output directory

[Andrey Albershteyn]

On immutable systems with read-only system packages, 'ln' will fail to
link .out files into system xfstests root directory. Fix this by linking
golden output file to the results output directory as a .out.good.

[PATCH v3 3/4] generic/452: make coping work with multi-call binary

[Andrey Albershteyn]

On some system coreutils binaries are all symlink to the single
coreutils binary. Just copying 'ls' will not work in this setup,
especially, with the different binary name.

Add 'realpath' to find out the real binary is make it behave like an
'ls' by renaming it to 'ls'.

Seems fine to me, though I wonder if we should change this to copy
/bin/echo instead of ls so that the output is more stable...

[PATCH v3 4/4] xfstests: fix permissions on system file installed by libtoolize

[Andrey Albershteyn]

Libtoolize installs set of auxiliary files from its system package.
Not all distributions have the same permissions set on these files.
For example, read-only libtoolize system package will copy those
files without write permissions. This causes build to fail as next
line copies ./include/install-sh over ./install-sh which will fail.

Fix this by setting permission explicitly on files copied by libtoolize.

See similar commit in xfsprogs:
6b32423addd2 ("xfsprogs: fix permissions on files installed by libtoolize")
