Subject: lib-storage: raw-mail - Cast st_size to uoff_t
X-Git-Tag: 2.3.13~64
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=edb32ea0e8cfcf3c76f30f7a59ab84b8ec349fc2;p=thirdparty%2Fdovecot%2Fcore.git

lib-storage: raw-mail - Cast st_size to uoff_t

mbox->size is unsigned field, and st_size will be -1
is the stat target is not regular file or symbolic link.
This can happen if it's stream like stdin.
