04a17095be Always use our own strtonum and implement sudo_strtoid in terms of it. 2019-10-14 10:09:29 -06:00

396bc57fef Add sudo_strtoid() tests for -1 and range errors. 
Also adjust testsudoers/test5 which relied upon gid -1 parsing.

f752ae5cee Treat an ID of -1 as invalid since that means "no change". 
Fixes CVE-2019-14287.

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.

30a56af6ef FreeBSD's /dev/fd only contains fds 0-2 unless fdescfs is mounted.

731e796711 Fix the counting of supplementary groups on AIX. 
We should not assume that basegid will be present in the list of
gids returned by getgrset().

17ca31c381 Ignore EOVERFLOW from pstat_getproc(), it is not a fatal error. 
It just means that one of the fields in pstat lacks the precision to
store a value.  That's not an issue for pst_highestfd.

985600e7f0 Minor snprintf() usage tweaks: 
1) don't assume snprintf() returns -1 on error, check for <0
2) when comparing return value of sizeof(foo), cast the sizeof, not the len
3) cast return value to void in cases where snprintf cannot fail

f7d7a9a619 Fix the default nofiles and stack hard limits. 
The table of default hard limits in /etc/security/limits was out
of date with respect to the current documentation.  The default
hard limit for nofiles should be unlimited, not 8196.  The default
hard limit for stack should be 4194304 blocks (which fits in an
unsigned long on 32-bit platforms).

ffe2041a02 Skip sudo_getgrouplist2() check on systems with getgrouplist_2(). 
sudo_getgrouplist2() is just a wrapper on such systems and this
avoids a test failure on macOS where a user is automatically a
member of certain groups.

cb588f2337 Pass --sourcetree-root to pvs-studio and don't check sudo_noexec.c. 
Since we don't auto-generate dependencies for sudo_noexec.c we
can't easily check it from outside the source tree.  This
is not a problem as it just contains stub functions.
