With -n -b file, a.out boot images can be used for CD booting;
with the new -n -B file option, plain binary (like bootxx_cd9660)
can be used instead.
Restore working the -h and -f options while there.
And add a new -F option for 2.8MB floppy image.
Register file timestamps
Remember the path tables in the primary descriptor
Put the size of the parent directory in the \1 entry, not own size
Allow the use of -b option without -a
Notes:
* Still missing the man page
* Filenames are still trimmed to 12 characters, because of
8.3 MS-DOS inherited compatibility (ISO9660 level 1);
also note that 7.4 or 9.2 filenames are accepted though
* Final . at end of filenames without extension is still missing
* VMS-compatible ;1 version suffix is still omitted
* Limit of 65,535 directories in path tables is not checked
Instead of using rootdev= or ramimagedev= in the boot monitor
which are changed to numbers and cannot be used with other
loaders, rootdevname= or ramimagename= are (MINIX-style)
device names always stored as strings.
Patch by Antoine Leca.
Kernels and system services are stored in a single directory in the
/boot/minix/ and rotated like /boot/images. /boot/minix_latest slink
is created automatically.
System serives are prefixed by "modNN_" to allow to easily load them
using "mod*" pattern.
Boot stuff dependencies from NetBSD.
Patch by Antoine Leca. Relocated to src/sys.
The port is using the same libminc.a as usual MINIX services (and does
not use NetBSD libkern); the headers imported from NetBSD sys/ tree
have been kept to a minimum (still numbers higher than 30 though.)
Note the peculiar way to use libraries (libsa, libi386, etc.): the
source code is shared, but each component builds its own copy of the
library, with its own set of preprocessor defines.
Also following functionality was added:
- Add install_master to the installboot from NetBSD.
- Check if enough space for bootxx.
Old installboot was renamed to installboot_minix.
- When cancelling ioctls, VFS did not remember which file descriptor
to cancel and sent bogus to the driver.
- Select state was not cleaned up when select()ing process was
interrupted.
- Process trying to do a system call at the exact same time as a user
trying to interrupt the process, could cause the system call worker
thread to overwrite state belonging to the worker thread trying to
exit the process. This led to hanging threads and eventual system hang
when this happens often enough.
When a mount operation fails and the FS exits, free_proc could try and
clean up resources associated with the mount point before the mount
thread itself can do that. However, the clean up procedure should only
clean up resources that were actually in use.
Currently, all servers and drivers run as root as they are forks of
RS. srv_fork now tells PM with which credentials to run the resulting
fork. Subsequently, PM lets VFS now as well.
This patch also fixes the following bugs:
- RS doesn't initialize the setugid variable during exec, causing the
servers and drivers to run setuid rendering the srv_fork extension
useless.
- PM erroneously tells VFS to run processes setuid. This doesn't
actually lead to setuid processes as VFS sets {r,e}uid and {r,e}gid
properly before checking PM's approval.
- this patch fixes a deadlock which may occur if we get a
spurious interrupt while calibrating clocks during the boot
time. Since we never handle interrupts while in the kernel
(BKL locked) the interrupt code locks the lock. This is a
different situation, a corner case, boot time only. We do not
return to userspace but to the kernel, so the BKL is not
unlocked. So we need irq handler which leaves the BKL
unlocked. The clock handler does it already, this patch adds
a dummy spurious irq handler for the same reason. It is better
to handle the situation this way to keep the normal runtime
code simple.
- this is a temporary change which makes images compiled for SMP
boot in SMP mode by default.
- this change is needed until we can configure the multiboot
images from the boot loader again.
