Bug ID: 18675
Summary: fpathconf(_PC_NAME_MAX) fails against large
filesystems for 32bit processes
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jmaggard at netgear dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 8439
--> https://sourceware.org/bugzilla/attachment.cgi?id=8439&action=edit
Proposed fix
Basically identical to bug #15514.
fpathconf(_PC_NAME_MAX) is implemented on top of fstatfs(). The 32bit version
therefore fails with the error EOVERFLOW if the filesystem that the path is on
is so large that its block count cannot be returned by the non-LFS version of
fstatfs().
Calls to fstatfs() that are completely internal to libc, such as this one,
should use the LFS version, __fstatvfs64().

The patch looks good to me.
Can you mail to libc-alpha@sourceware.org for approval?
