See my note from yesterday about quota size displays for reference
I have just been looking at the source code. (long time since I did
C, so forgive me if I stuff something up royally)
in source/smbd/ntquotas.c there is code that corrects for block sizes
other than 1024, which would work correctly IFF the *bsize is set
correctly (should be 512 on my FreeBSD system but i don't know how to
debug stuff on FreeBSD to see the value actually used).
ie
if ((*bsize) < 1024) {
dfree_retval = (*dfree)/(1024/(*bsize));
} else {
dfree_retval = ((*bsize)/1024)*(*dfree);
would do the job to report the correct number of 1024 byte blocks to
Windows.
however, I'm seeing a report of twice the size, which indicates that
*bsize is set to 1024.
in /source/smbd/quotas.c I find this
#if defined(__FreeBSD__) || defined(__OpenBSD__)
*bsize = DEV_BSIZE;
great. so the blocksize is set, however I am failing miserably to
find the actual definition of DEV_BSIZE, except to see it seems to
come from STAT_ST_BLOCKSIZE, which may or may not be set to 512, the
'configure' file is out of my league, and that is where it seems to
be defined.
I see things like
configure.in: AC_DEFINE(STAT_ST_BLOCKSIZE,512,[The size of a block])
configure.in: AC_DEFINE(STAT_ST_BLOCKSIZE,DEV_BSIZE,[The size of a
block])
but I find nowhere where DEV_BSIZE is set to anything other just a
#define DEV_BSIZE
which as far as I can recall sets it to '1'
So, I conclude there is definitely something buggy in this code that
is causing smbd to return the raw count of blocks to Windows clients
when a quota is set on FreeBSD 5.2.1. Yet, the size is correct when
no quota is set on a share.
Please can the people who know how to fix this, fix it.
