Bug #: 15514
Summary: pathconf(_PC_NAME_MAX) fails against large filesystems
for 32bit processes
Product: glibc
Version: 2.17
Status: NEW
Severity: critical
Priority: P2
Component: libc
AssignedTo: unassigned@sourceware.org
ReportedBy: guenther@gmail.com
CC: drepper.fsp@gmail.com
Classification: Unclassified
pathconf(_PC_NAME_MAX) is implemented on top of statfs(). 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
statfs().
Calls to statfs() that are completely internal to libc, such as this one,
should use the LFS version, statfs64().
According to a quick scan of the glibc source, other calls that might be
affected include posix_openpt() and (maybe) shm_open().

Most of the pathconf queries use statvfs64(), so it didn't seem unreasonable to make _PC_NAME_MAX do the same. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
