dholland | Add containment for the cloning devices hack in vn_open.
Cloning devices (and also things like /dev/stderr) work by allocating
a struct file, stuffing it in the file table (which is a layer
violation), stuffing the file descriptor number for it in a magic
field of struct lwp (which is gross), and then "failing" with one of
two magic errnos, EDUPFD or EMOVEFD.
Before this commit, all callers of vn_open in the kernel (there are
quite a few) were expected to check for these errors and handle the
situation. Needless to say, none of them except for open() itself did,
resulting in internal negative errnos being returned to userspace.
This hack is fairly deeply rooted and cannot be eliminated all at
once. This commit adds logic to handle the magic errnos inside
vn_open; now on success vn_open returns either a vnode or an integer
file descriptor, along with a flag that says whether the underlying
code requested EDUPFD or EMOVEFD. Callers not prepared to cope with
file descriptors can pass NULL for the extra return values, in which
case if a file descriptor would be produced vn_open fails with
EOPNOTSUPP.
Since I'm rearranging vn_open's signature anyway, stop exposing struct
nameidata. Instead, take three arguments: an optional vnode to use as
the starting point (like openat()), the path, and additional namei
flags to use, restricted to NOCHROOT and TRYEMULROOT. (Other namei
behavior, e.g. NOFOLLOW, can be requested via the open flags.)
This change requires a kernel bump. Ride the one an hour ago.
(That was supposed to be coordinated; did not intend to let an hour
slip by. My fault.)

specfs changes for PR kern/37717 (raidclose() is no longer called on
shutdown). There are still problems with device access and a PR will be
filed.
- Kill checkalias(). Allow multiple vnodes to reference a single device.
- Don't play dangerous tricks with block vnodes to ensure that only one
vnode can describe a block device. Instead, prohibit concurrent opens of
block devices. As a bonus remove the unreliable code that prevents
multiple file system mounts on the same device. It's no longer needed.
- Track opens by vnode and by device. Issue cdev_close() when the last open
goes away, instead of abusing vnode::v_usecount to tell if the device is
open.

christos | PR/32682: Hauke Fath: netbsd-3 ptyfs intermittent failure with Matlab
For the benefit of linux emulation create a new minor device '2'
which is a ptmx with linux semantics. Linux changes the permissions
of the slave pty upon creation, not when grantpt(3) is called. The
glibc linux grantpt(3) checks that the pty is on ptyfs, and if it is,
it does nothing. To make use of this fix:
mknod /emul/linux/dev/ptmx c 165 2
chmod 666 /emul/linux/dev/ptmx
This is a lot simpler than copying a bunch of code and creating a
ptmx device just for the benefit of linux emulation.

pgoyette | Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line
rather than defining an intermediate hook##call function. Almost
all of the hooks are called only once, and although we lose the
ability of doing things like
if (MODULE_HOOK_CALL(...) == 0) ...
we simplify things quite a bit. With this change, we no longer need
to have both declaration and definition macros, and the definition
no longer needs to have both prototype argument list and a "real"
argument list.
FWIW, the above if now needs to written as
int ret;
MODULE_HOOK_CALL(..., ret);
if (ret == 0) ...
with appropriate use of braces {}.
|
| 1.37.16.5 |
| 18-Jan-2019 |
pgoyette | Don't restrict hooks to having only int or void types. Pass the hook's
type to the various macros, as needed.
Allows us to reduce diffs to original in at least one or two places (we
no longer have to provide an additional parameter to the hook routine
for returning a non-int return value).
|
| 1.37.16.4 |
| 14-Jan-2019 |
pgoyette | Create a variant of the HOOK macros that handles hook routines of
type void, and use them where appropriate.
|
| 1.37.16.3 |
| 13-Jan-2019 |
pgoyette | Remove the HOOK2 versions of the MODULE_HOOK macros. There were
only a few uses, and using them led to some lack of clarity in the
code. Instead, we now use two separate hooks, with names that
make it clear(er) what we're doing.
This also positions us to start unraveling some of the rtsock_50
mess, which will need (at least) five hooks.
|

will get resolved soon.
|

pgoyette | Rename LOCALCOUNT_INITIALIZER to DEVSW_MODULE_INIT. This better describes
what we're doing, and why.
|
| 1.37.2.2 |
| 19-Jul-2016 |
pgoyette | Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it. This also removes the need for defining new symbols
for each 'struct localcount'.
As suggested by riastradh@
|
| 1.37.2.1 |
| 18-Jul-2016 |
pgoyette | Rump drivers are always installed via devsw_attach() so we need to
always allocate a 'struct localcount' for these drivers whenever they
