+ Use _PATH_GROUP and _PATH_MASTERPASSWD (from OpenBSD)
+ Use -G group1,group2,group3 for multiple groups in useradd and usermod
(pointed out by Matt Green, and also changed in OpenBSD, but done more
efficiently here)
+ is_number should not be inside #ifdef EXTENSIONS (from OpenBSD)
+ clear up yet another usage message (for user(8) and group(8)) - noticed
in passing, unknown if fixed anywhere else
queueing up buffers and awakening the MFS server process to do the I/O,
we do the I/O to the server process's address space directly using
facilities provided by UVM.
This makes it possible for buffers attempting to flush out while the
MFS is being unmounted to actually do the I/O, where before it would
fail if the server process wasn't in the MFS idle loop (i.e. had been
signaled and was attempting to exit).
Should fix kern/10122 (I can no longer reproduce the problem described
in the PR when running with these changes), and any number of other
MFS-related complaints made by people over time.
with procfs's cmdline - from the PR:
The cmdline implementation in procfs is bogus. It's possible that
part of the fix is a workaround of a UVM problem - that is, when
(internally) accessing the top of the process VM (the end of the
args) a request for I/0 of a PAGE_SIZE'd block starting at less
than a PAGE_SIZE from the end of the mem space returns EINVAL
rather than the data that is available. Whether this is a bug
in UVM or not depends upon how it is defined to work, and I was
unable to determine that. (Simon Burge found that problem, and
provided the basis of the workaround/fix).
Then, the cmdline function is unable to read more than one
page of args, and a good thing too, as the way it is written
attempting to get more than that would reference into lala land.
And, on an attempt to read a lot of data when the above is
fixed, most of the data won't be returned, only the final block
of any read.
Tested on alpha, pmax, i386 and sparc.
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those
platforms should be changed to use device_register(). In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.
(though still not all) errors in a damaged lfs. Segment byte accounting
is corrected in pass 5. "fsck_lfs -p" will do a partial roll-forward,
verifying the checkpoint from the newer superblock. fscknames[] is
updated so that fsck knows about fsck_lfs.
