ac36cf2d4b In closefrom_fallback() use the interval [OPEN_MAX, INT_MAX]. 
We want to try closing at least OPEN_MAX fds but no more than INT_MAX.
On 64-bit systems it is possible for sysconf(_SC_OPEN_MAX) to return
a value larger than INT_MAX when the number of open files is unlimited.

396bc57fef Add sudo_strtoid() tests for -1 and range errors.

29534ad96a Fix handling of real-time signals. 2019-08-19 08:36:30 -06:00
Todd C. Miller
3e56be3564 Store signal name, not number in I/O log timing file. 
The "SIG" prefix is not used so, e.g. SIGTERM -> "TERM".
This makes the I/O log files portable from one system to another.
Older I/O log files with signal numbers can still be replayed.

e91865fb22 Link util functions being tested directly with the test harness. 
Otherwise we may get the version from the installed libsudo_util.so.

9d8f374397 Add ssizeof macro that returns ssize_t. 
We can use this instead of casting the result of size_t to int.
Also change checks for snprintf() returning <=0 to <0.

cd2cfeb8cb It is safe to assume _POSIX_VDISABLE is defined. 
The old compat defines were to support pre-termios systems.
