Summary: warning: comparison between signed and unsigned
Product: Portable OpenSSH
Version: 4.3p2
Platform: amd64
URL: http://www.openbsd.org/cgi-
bin/cvsweb/src/usr.bin/ssh/scp.c.diff?r1=1.121&r2=1.122&
f=h
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: scp
AssignedTo: bitbucket@mindrot.org
ReportedBy: carenas@sajinet.com.pe
introduced as part of scp version 1.122 (OpenBSD 3.8/OpenSSH 4.2), and
which results in the following warning when compiled with
-Wsign-compare :
scp.c: In function `source':
scp.c:632: warning: comparison between signed and unsigned
scp.c:639: warning: comparison between signed and unsigned
the problem is that off_t is defined signed (long long for OpenBSD and
long int for linux/amd64), while size_t is unsigned (unsigned long for
OpenBSD and long unsigned int for Linux).
for LPI32 architectures (like i386), the expansion from unsigned long
(4 bytes) to long long (8 bytes) is safe, but no so for LP64
architectures (like amd64) where "long long" and "unsigned long" are 8
bytes wide.
