From 6ae3a3a5ac74100e2eaa13be67050780ea0004fb Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sun, 18 Jul 2021 10:17:46 -0500 Subject: [PATCH] generic/423: test stx_size of symlink Update generic/423 to test that the reported size of a symlink is equal to the length of the symlink target, as required by POSIX and as documented in various man pages. When the test_dummy_encryption mount option is enabled, this serves as a regression test for the bug that will be fixed by the patch series "fscrypt: report correct st_size for encrypted symlinks" (https://lkml.kernel.org/r/20210702065350.209646-1-ebiggers@kernel.org). However, this test is applicable to all filesystems and mount options.
