- Fix locking bug when unable to send DEV_SELECT request. Upon failure
VFS tried to cancel the select operation, but this failed due to trying
to lock a filp that was already locked to send the request in the first
place. Do_select_request now handles locking of filps itself instead of
relying on the caller to do it. This fixes a crash when killing INET.
- Fix failure to revive a process after a non-blocking select operation
yielded no ready select operations when replying DEV_SEL_REPL1.
- Improve readability by using OK, SUSPEND, and standard error values as
results instead of having separate macros in select.
- Don't print not having a driver for a major device; after killing a driver
select will trigger this printf.
. harmonize bsd.lib.mk and bsd.man.mk with netbsd files
. throw out minix section 3 (library calls) manpages,
replaced by netbsd ones that are now installed
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
. we cannot use the boot monitor to print the system diag buffer
. for serial, we do nothing, just reset, everything is already printed
. for not-serial, we print the current diag buffer using direct video
memory access from the kernel
Add guard pages to the top of the stack to catch overflow errors.
Moreover, fix a bug where libmthread would keep using a stack that was
just deallocated; a detached thread would deallocate its own stack after
it was finished running).
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
