16ae61dcd7 Use C23 [[__fallthrough__]] and [[__noreturn__]] attributes if supported. 
If the C23 attributes are not supported, use gcc-style attributes
where possible.

803998d2bd Only add trailing carriage return to messages if output is a raw tty. 
If output is being written to a terminal in "raw" mode, we need to
add a carriage return after the newline to avoid "stair-step" output.
However, we should not write the carriage return if the terminal
is in "cooked" mode, output to a pipe, or output redirected to a file.
Bug #1042.

88ac5e09b6 Use sudo_secure_open_file() instead of sudo_secure_file() where possible. 
Both sudo_secure_open_file() and sudo_secure_open_dir() are now passed
a struct stat pointer like sudo_secure_file() and sudo_secure_dir().

304726a215 Move gcc-style __attribute__ macros to config.h.in 
Renamed __malloc -> sudo_malloclike, __printflike -> sudo_printflike,
__printf0like -> sudo_printf0like.
Add sudo_noreturn instead of __attribute__((__noreturn__)).
We do not use stdnoreturn.h since it has been deprecated in C23
in favor of the [[noreturn]] attribute.

fccf3c9c56 Add sudo_mmap_{alloc,allocarrary,strdup,free} functions. 
These allocate memory via mmap anonymous regions and store the mapped
size immediately before the returned pointer as an unsigned long.
They are intended to be used in cases where malloc(3) and free(3)
are unsuitable due to concerns about corrupting global state in
multi-threaded programs or signal handlers.

3cd9c5f5e6 Stop sending an InterceptResponse to a PolicyCheckRequest for log_subcmds. 
There's no real reason for the command to wait for sudo send back a
response that will always be a PolicyAcceptMessage.

b77cbb2e67 Fix building with select (not poll) when fd_set is not defined in sys/types.h. 
We can use a void * for the fd_set arrays and just add a cast when
using the FD_SET macros.

9ac42292d1 Bump plugin minor version and document new intercept-related settings. 
There should have been a minor version bump for sudo 1.9.8 when
intercept was originally implemented.

bd25b85a66 Add an apparmor_profile sudo setting 
Define a new sudo setting, `apparmor_profile`, that can be used to pass
in an AppArmor profile that should be used to confine commands. If
apparmor_profile is specified, sudo will execute the command using the
new `apparmor_execve` function, which confines the command under the
provided profile before exec'ing it.

46edc4e198 Stop using the WCONTINUED flag with waitpid(2). 
We don't use it for anything other than a debug message and it will
cause problems when intercept mode starts using ptrace(2).

2e957cd43d Fix compilation on Debian kFreeBSD. 
The configure script correctly detects that utimensat() and futimens()
are missing but the headers define stub versions of the functions.
Including sys/stat.h pulls in the system definitions  so we can override
them safely.  Bug #1021.

replaced with '*' chars until a newline or another tty output
character is received.

bddf03fe45 No longer need to pass exit params to eventlog_exit(), use struct eventlog. 
Now that struct eventlog includes the exit parameters we can simplify
how eventlog_exit() is called.

a554629d84 Flush I/O logs before we send a commit point.

9a690a8984 Switch to a 128-bit token instead of a 64-bit secret. 
Protobuf doesn't have a 128-bit type so use two u64s.
We now support partial reads of the token.

9137909c7d sudo_intercept.so: send the secret immediately after connecting. 
Sending the secret out of band, before the message size is read,
should make it harder to mount a DoS attack.

Since sudoers does rejected commands itself the runcwd will still
not be correct for those.
