Bug ID: 29097
Summary: fchmodat does not handle 64 bit time_t for
AT_SYMLINK_NOFOLLOW
Product: glibc
Version: 2.34
Status: NEW
Severity: normal
Priority: P2
Component: time
Assignee: unassigned at sourceware dot org
Reporter: adhemerval.zanella at linaro dot org
Target Milestone: ---
Since Linux fchmodat syscall does not provide a 'flag' argument (to
handle AT_SYMLINK_NOFOLLOW), glibc emulates it through opening a procfs file
descriptor, issuing fstatat to check if it is link (since some kernels and
filesystem it returns in inconsistent results), and then issue chmod.
However, the glibc internal fstat does not use the 64-bit version, which
then results in EOVERFLOW.
