I noticed that too, and my quick&dirty fix was to make quota_get_status() call quota_test_alloc() with size = 1, which fixes the problem as well. See patch below [1].
didn't work, so I traced down the problem:
quota_get_status (quota_storage.c:89) calls quota_test_alloc (quota.c:1352) with size = 0 bytes, which leads always to a FALSE result in quota_is_over (quota.c:1305).
I've fixed the function quota_is_over by considering ctx->bytes_over and ctx->count_over. See the included patch.
I keep wondering why quota_is_over() does not just check ctx->*_over in the first place instead of doing math with ctx->*_used and ctx->*_ceil. It would seem so much easier. So either ctx->*over was added after quota_is_over() had been written, or this is an oversight, or there’s a specific reason the author did not use/trust ctx->*_over and preferred doing it in a more complicated way. Grepping trough the file, I see much more places the the ctx->*_used and ctx->*_ceil get updated compared to ctx->*_over, so that might indicate that the latter is only updated in specific cases, and cannot be trusted under all circumstances. Then again, I just took a short look at the quota code, so this hunch might me completely wrong.
