- fail SEF initialization if any of the subtests failed, so that the
party invoking the "service up" can tell whether the test succeeded;
- add "nocontig" option, because VM isn't particularly good at
allocating contiguous memory;
- add "silent" option, because it floods the console otherwise;
- allow the device size to be smaller than the maximum transfer size;
- install files to installed test directory.

- check each file descriptor's open access mode (filp_mode);
- treat an error returned by a character driver as a select error;
- check all filps in each set before finishing select;
- do not copy back file descriptor sets if an error occurred;
- remove the hardcoded list of supported character major devices,
since all drivers should now be capable of responding properly;
- add tests to test40 and fix its error count aggregation.

* Removed startup code patches in lib/csu regarding kernel to userland
ABI.
* Aligned stack layout on NetBSD stack layout.
* Generate valid stack pointers instead of offsets by taking into account
_minix_kerninfo->kinfo->user_sp.
* Refactored stack generation, by moving part of execve in two
functions {minix_stack_params(), minix_stack_fill()} and using them
in execve(), rs and vm.
* Changed load offset of rtld (ld.so) to:
execi.args.stack_high - execi.args.stack_size - 0xa00000
which is 10MB below the main executable stack.

testmfs: catch MFS format changes
This test tests mkfs.mfs will generate the same FS image given the same
input files. mkproto creates a proto file (normalizing directory entry
order). The assumption is that a change in the output flags a tacit
change in FS format, and that a FS format change will cause the image
to change.
. Changes to mkfs.mfs that innocently change the format can
change the sha1 output in the script along with it.
. The assumption is that corresponding versions of mkfs.mfs and
MFS will always work together; otherwise a lot breaks (ramdisk etc.)
. Therefore, as long as a generated FS image stays the same with the
same input now, incompatible MFS changes will still be flagged,
even if they work together with the current mkfs.mfs.
testisofs: test ISO filesystem
. to test isofs: prepare an ISO FS image using writeisofs, copy it
to a RAM device, mount it using the iso9660fs server, compare the
SHA1 contents of the files on the ISO with the inputs.
. use su to run certain commands in the script as root
run script: run shell script tests
. they are installed without .sh so should be
searched for as such
. add diagnostic when tests are skipped

-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.
Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.
-Reduce difference with NetBSD share/mk
Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.
-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)
-Correct minix.h header sequence, cleanup spec headers.
-Fix cross-compilation from a 32bit host targeting MINIX/arm

. test74 for mmap functionality
. vm: add a mem_file memory type that specifies an mmap()ped
memory range, backed by a file
. add fdref, an object that keeps track of FD references within
VM per process and so knows how to de-duplicate the use of FD's
by various mmap()ped ranges; there can be many more than there can
be FD's
. turned off for now, enable with 'filemap=1' as boot option
Change-Id: I640b1126cdaa522a0560301cf6732b7661555672
Primary purpose of change: to support the mmap implementation, VM must
know both (a) about some block metadata for FS cache blocks, i.e.
inode numbers and inode offsets where applicable; and (b) know about
*all* cache blocks, i.e. also of the FS primary caches and not just
the blocks that spill into the secondary one. This changes the
interface and VM data structures.
This change is only for the interface (libminixfs) and VM data
structures; the filesystem code is unmodified, so although the
secondary cache will be used as normal, blocks will not be annotated
with inode information until the FS is modified to provide this
information. Until it is modified, mmap of files will fail gracefully
on such filesystems.
This is indicated to VFS/VM by returning ENOSYS for REQ_PEEK.

This commit removes the secondary cache code implementation from
VM and its usage from libminixfs. It is to be replaced by a new
implementation.

. test70: regression test for m_out vfs race condition
The following tests use testcache.c to generate test i/o
patterns, generate random write data and verify the reads.
. test71: blackbox full-stack test of FS operation, testing
using the regular VFS interface crazy i/o patterns
with various working set sizes, triggering only
primary cache, also secondary cache, and finally
disk i/o and verifying contents all the time
. test72: unit test of libminixfs, implementing
functions it needs from -lsys and -lblockdriver
and the client in order to simulate a working
cache client and backend environment.
. test73: blackbox test of secondary vm cache in isolation

upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
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
. so that functionality is tested
. add test63 that actually tests dlopen(), dlsym(),
etc. functionality; only built if clang supports it
. also test10 test to copy more of the executable
Previously, user processes could cause a kernel panic upon FPU state
restore, by passing bogus FPU state to the kernel (through e.g.
sigreturn). With this patch, the process is now sent a SIGFPE signal
instead.
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.
Changes in this commit:
. drop boot monitor -> allowing dropping ack support
. facility to copy ELF boot files to /boot so that old boot monitor
can still boot fairly easily, see UPDATING
. no more ack-format libraries -> single-case libraries
. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
. drop several ack toolchain commands, but not all support
commands (e.g. aal is gone but acksize is not yet).
. a few libc files moved to netbsd libc dir
. new /bin/date as minix date used code in libc/
. test compile fix
. harmonize includes
. /usr/lib is no longer special: without ack, /usr/lib plays no
kind of special bootstrapping role any more and bootstrapping
is done exclusively through packages, so releases depend even
less on the state of the machine making them now.
. rename nbsd_lib* to lib*
. reduce mtree
This patch fixes most of current reasons to generate compiler warnings.
The changes consist of:
- adding missing casts
- hiding or unhiding function declarations
- including headers where missing
- add __UNCONST when assigning a const char * to a char *
- adding missing return statements
- changing some types from unsigned to signed, as the code seems to want
signed ints
- converting old-style function definitions to current style (i.e.,
void func(param1, param2) short param1, param2; {...} to
void func (short param1, short param2) {...})
- making the compiler silent about signed vs unsigned comparisons. We
have too many of those in the new libc to fix.
A number of bugs in the test set were fixed. These bugs were never
triggered with our old libc. Consequently, these tests are now forced to
link with the new libc or they will generate errors (in particular tests 43
and 55).
Most changes in NetBSD libc are limited to moving aroudn "#ifndef __minix"
or stuff related to Minix-specific things (code in sys-minix or gen/minix).
