059b55ce72 Refactor code in sudoers that creates I/O log files to share with logsrvd. 2019-10-24 20:04:31 -06:00

c3ce3a84fb Refer to user-ID and group-ID instead of "user ID" and "group ID" 2019-10-19 14:26:41 -06:00

40bf4081be Rename sudo_strtoid() to sudo_strtoidx() and add simplified sudo_strtoid() 2019-10-20 10:21:29 -06:00

2512f6efbf Use sudo_strtonum() explicitly instead of via a macro. 2019-10-14 10:09:30 -06:00

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.

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.

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

cf07dc0757 Add a suspend event type to the I/O log to log suspend/resume of 
the command so we can skip that delay during replay.

0d36ea9325 We cannot reuse last_time for the I/O log info file now that it is 
a monotonic timer.  Just call time(3) in write_info_log() directly.

3f1470ebed Use a monotonic timer that only runs while not suspended for the 
iolog timing values and write nsec-precision entries.

afad4eb94d Fix I/O log timing file on systems without a C99-compatible snprintf(). 
On those systems we use our own snprintf() that doesn't support
floating point.  We don't actually need floating point in this case
since the we can print seconds and microseconds without using it.

418bf793f7 Fix the return value of sudoers_io_change_winsize() on success. 
Otherwise, we only log a single window size change.

a885b952fb Remove use of AC_HEADER_TIME, only obsolete platforms actually 
need this.  Also stop removing sys/time.h unless the source file
uses struct timeval.

(currently ignored).

1d1ebb6111 Add io_open() wrapper for open(2) that retries with PERM_IOLOG if 
open(2) fails with EACCES.  Use io_open() instead of duplicate
copies of the same fallback code.

4df6b62b56 Only retry mkdir or create with PERM_IOLOG if errno is EACCES. 
Also always use PERM_IOLOG for mkdtemp() since we cannot retry
if it fails.  Since we are guaranteed to create a new directory
there's no real need to try w/o PERM_IOLOG in this case.

7668b4b42b Set umask temporarily when creating files instead of changing the 
mode after the fact.  This is slightly less error prone.

affected by the invoking user's umask.

8d57491dc1 Add PERM_IOLOG so we can create I/O log files on an NFS-mounted 
filesystem where root is remapped to an unprivileged user.

8c8d078f66 Don't allow the user to specify an I/O log file mode that sudo can't 
read or write to.  I/O logs must always be readable and writable
by the owner.

6c5936296f Add SUDO_DEBUG_INSTANCE_ERROR return value for sudo_debug_register()

sudo_debug_register().

3f022419ae Be consistent with the naming of the variable used to store the 
function return value.  Previously, some code used "rval", some
used "ret".  This standardizes on "ret" and uses "rc" for temporary
return codes.

3e4c7eed31 Move the ignoring of I/O log plugin errors into the I/O log plugin 
itself.

ed18d0d5f8 Make the behavior when we cannot write to a log or audit file 
configurable.  File log failures are ignored by default for consistency
with syslog.  Audit errors are ignored by default to allow the admin
to fix the issue.  I/O log file errors are still fatal by default
since if I/O logging is activated it is usually to have an audit trail.

05db5aa3b8 Remove sudo_mkpwcache() and sudo_mkgrcache(). We now create the 
caches as needed on demand.  Also remove calls to sudo_freepwcache()
and sudo_freegrcache() that are immediately followed by execve(),
they are not needed.

23d288563e Eliminate use of setpwent()/endpwent() and setgrent()/endgrent(). 
Sudo never iterates over the passwd or group file.
Rename sudo_set{pw,gr}ent() -> sudo_mk{pw,gr}cache() and
use sudo_free{pw,gr}cache() instead of sudo_end{pw,gr}ent().

c56a812ea2 In io_mkdirs(), change the order from stat then mkdir, to mkdir then stat. 
This more closely matches what "mkdir -p" does.
