This still causes crashes in mountd on 32bit systems without
https://marc.info/?l=linux-nfs&m=157250894818731&w=2
mountd: Version 2.4.2 starting
mountd: auth_unix_ip: inbuf 'nfsd fde2:2b6c:2d24:0021:0000:0000:0000:0050'
mountd: auth_unix_ip: client 0x13cd900 '*'
mountd: nfsd_fh: inbuf '* 6 \xd1fb45ab77b345d99b09b3217dcdf2ec'
*** stack smashing detected ***: <unknown> terminated
Aborted
Call chain looks like:
get_rootfh utils/mountd/mountd.c
check_is_mountpoint support/misc/mountpoint.c
nfsd_path_lstat support/misc/nfsd_path.c *
xlstat support/misc/xstat.c *
where two struct stats are declared on the stack in mountpoint.c without
including config.h and getting the __USE_FILE_OFFSET64 define, however
the following two files in the call chain include config.h and get a
different size struct stat.
Also attached are a few printf formating fixes for 32 bit.
