linux: Fix fchmodat with AT_SYMLINK_NOFOLLOW for 64 bit time_t (BZ#29097)
|
|
|
|
The AT_SYMLINK_NOFOLLOW emulation ues the default 32 bit stat internal
|
|
calls, which fails with EOVERFLOW if the file constains timestamps
|
|
beyond 2038.
|
|
|
|
Checked on i686-linux-gnu.
|
|
|
|
(cherry picked from commit 118a2aee07f64d605b6668cbe195c1f44eac6be6)
