buffer overflows at various snprintf()

[Enrico Scholz]

Hello,

compiling 2.1.13 gives some serious compiler warnings:

| cfagent.c:1100: warning: call to __builtin___snprintf_chk will always 
overflow destination buffer
| do.c:637: warning: call to __builtin___snprintf_chk will always overflow 
destination buffer
| do.c:3285: warning: call to __builtin___snprintf_chk will always overflow 
destination buffer
| crypto.c:297: warning: call to __builtin___snprintf_chk will always overflow 
destination buffer
| crypto.c:52: warning: call to __builtin___snprintf_chk will always overflow 
destination buffer
| cfenvd.c:283: warning: call to __builtin___snprintf_chk will always overflow 
destination buffer
| cfenvgraph.c:1021: warning: call to __builtin___snprintf_chk will always 
overflow destination buffer


This is caused by statements like

| char   buf[A];
| snprintf(buf, B, ...);

where A<B  (probably just typos).



CVS snapshot + SVN tree are unavailable currently so I can not check if
this was fixed already.
