From d0a59e67fedf760a02109f5c18281241c6caa654 Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Fri, 25 Feb 2022 19:36:10 +0100 Subject: Fix store_read calls store_read takes a look at the size to determine whether to fill the provided buffer or not. Even if providing a null buffer we should set the size to 0. * defpager/defpager.c (pager_read_page): Initialize nread to 0. * storeio/dev.c (buffered_rw): Initialize amount to 0. * fatfs/fat.c (fat_read_sblock): Initialize read to the size of the boot sector. Reuse it as such. --- storeio/dev.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'storeio/dev.c') diff --git a/storeio/dev.c b/storeio/dev.c index 8726c94c..4f48d081 100644 --- a/storeio/dev.c +++ b/storeio/dev.c @@ -269,7 +269,7 @@ buffered_rw (struct dev *dev, off_t offs, size_t len, size_t *amount, { if (len >= block_size) { - size_t amount; + size_t amount = 0; err = dev_buf_discard (dev); if (! err) err = -- cgit v1.2.3
