test69 requires superuser powers to adjust the time. This caused
the test to fail when run as a normal user. The patch adds test69
to the setuid list which will allow regular users to execute it.
Patch contributed by Antoine Leca.
This also adds the sys_settime() kernel call which allows for the adjusting
of the clock named realtime in the kernel. The existing sys_stime()
function is still needed for a separate job (setting the boottime). The
boottime is set in the readclock driver. The sys_settime() interface is
meant to be flexible and will support both clock_settime() and adjtime()
when adjtime() is implemented later.
settimeofday() was adjusted to use the clock_settime() interface.
One side note discovered during testing: uptime(1) (part of the last(1)),
uses wtmp to determine boottime (not Minix's times(2)). This leads `uptime`
to report odd results when you set the time to a time prior to boottime.
This isn't a new bug introduced by my changes. It's been there for a while.
In order to make it more clear that ticks should be used for timers
and realtime should be used for timestamps / displaying the date/time,
getuptime() was renamed to getticks() and getuptime2() was renamed to
getuptime().
Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2()
have been updated. In instances where a realtime was calculated, the
calculation was changed to use realtime.
System calls clock_getres() and clock_gettime() were added to PM/libc.
When you provided a string with junk after the terminating nul to a
UNIX domain socket and used bind(2), the canonical path function would
not properly terminate the new string. This caused VFS to return
ENAMETOOLONG on an otherwise valid path name.
Test case is added to test56.

Select(2)ing on UNIX domain sockets was not working properly because
connection state wasn't properly checked/propagated. So selecting for
a read descriptor and closing the write descriptor on the other end
didn't cause select to return. Similarly, read(2) kept blocking while
it should return an error when the other end closed the socket.

if an exec() fails partway through reading in the sections, the target
process is already gone and a defunct process remains. sanity checking
the binary beforehand helps that.
test10 mutilates binaries and exec()s them on purpose; making an exec()
fail cleanly in such cases seems like acceptable behaviour.
fixes test10 on ARM.

So we don't have to figure out which line generated this error by
searching for the subtest/error code combination.

Adding the bomb function which takes as a parameter a string
to be printed, print it, cleans up and exits with an error
code. It also means they will exit after the first error, unlike
previous behaviour.

test3 performs tests for null pointers but after that still continues
and uses them. This results in segfault's. Fixing this issue by failing
on the first error.

Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
. also make other out-of-memory conditions less fatal
. add a test case for a user program using all the memory
it can
. remove some diagnostic prints for situations that are normal
when running out of memory so running the test isn't noisy
rm -rf works just fine no matter what mode bits are set (modulo
file ownership and current user id). Test 43 creates a symlink
to / and the chmod operation would change file permissions outside
of the test directory.
- use one single library instead of loose library files
- we don't have ftime() anymore
- shmat(non-NULL) is currently broken, fix shmt test set to bypass this
- some other small issues
. if the layout of virtual address regions as returned
by mmap() without a location hint changes, ld.so could
trip itself up (under minix). this change allocates
the full size it needs for every object that's loaded
so that if that succeeds, it's sure there's virtual address
space for the whole thing no matter what other bits happen
to be there already.
. this fix exposed a bug in the test; at atexit() execution
time the loaded object is unmapped, so that part of the
test is removed.
. all invocations were S or D, so can safely be dropped
to prepare for the segmentless world
. still assign D to the SCP_SEG field in the message
to make previous kernels usable
POSIX mandates that a file's modification and change time be left
untouched upon truncate/ftruncate iff the file size does not change.
However, an open(O_TRUNC) call must always update the modification and
change time of the file, even if it was already zero-sized. VFS uses
the file systems' truncate call to implement O_TRUNC. This patch
replaces git-255ae85, which did not take into account the open case.
The size check is now moved into VFS, so that individual file systems
need not check for this case anymore.
