On the kernel side, git blame says: [/usr/src/linux-next] git blame include/linux/errno.h | grep -C 5 524 ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 22) ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 23) /* Defined for the NFSv3 protocol */ ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 24) #define EBADHANDLE 521 /* Illegal NFS file handle */ ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 25) #define ENOTSYNC 522 /* Update synchronization mismatch */ ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 26) #define EBADCOOKIE 523 /* Cookie is stale */ ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 27) #define ENOTSUPP 524 /* Operation is not supported */ ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 28) #define ETOOSMALL 525 /* Buffer or request is too small */ ^1da177e4c3f4 (Linus Torvalds 2005-04-16 15:20:36 -0700 29) #define ESERVERFAULT 526 /* An untranslatable error occurred */ So I'm mystified why glibc's strerror() doesn't handle it. Though I think Alexander is correct on why the kernel returns ENOTSUPP. I've updated the bugzilla entry.
