to be a caddr_t, but since it's being passed constant user argument pointers
it needs to be const, and since it's being passed a variety of argument
pointer types it makes sense to change it to void *. That argument is
simply being handed to copyin().
'const char *', and 'void *', respectively. The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions. The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
__builtin_classify_type() into harmless values, so that lint doesn't
get confused, think they're real functions, and that they're being
invoked in the wrong ways.
shell's idea of the current working directory match reality when
symlinks (or anything else we can't stat) are traversed with the
cd command. However, this does not print out the cwd after cd
traverses symlinks, as it used to, though the capability is still
there should one want to use it.
* change in-kernel syscall prototypes to match user-land prototypes in
the following ways:
+ add 'const' where appropriate.
+ make the following "safe" type changes where appropriate:
caddr_t -> struct msghdr *
caddr_t -> struct sockaddr *
caddr_t -> void *
char * -> void *
int -> uid_t (safe because uid_t not used as index/count)
int -> gid_t (safe because gid_t not used as index/count)
u_int -> size_t
+ change "int" to "u_long" in flags arguments to chflags() and
fchflags(). This is safe because the arguments are used as
flag bits and there's nothing that would cause the top bit
of the int to be set yet, and because the user-land definitions
already specified u_long, so a u_long's worth of argument was
already being passed in.
wrong for a bunch of functions:
void: sys_exit, sys_sync
ssize_t: sys_read, sys_write, sys_recvmsg, sys_sendmsg,
sys_recvfrom, sys_readv, sys_writev, sys_sendto
long: sys_pathconf, sys_fpathconf
void *: sys_shmat
* Note that sys_open, sys_ioctl, and sys_fcntl are defined such that their
last argument is optional.
These changes should not have any real effect, because right now this
information is not actually used for anything.
* Don't output prototypes for INDIR syscalls (since they always show up as
sys_nosys() in the syscall table).
* Add "indir" to the comment for INDIR syscalls in the syscalls table, so
it's more obvious why they call sys_nosys().
* Deal with multi-word system call return types (i.e. foo *, or
struct foo *, or struct foo, etc.).
* Add a new class of system calls "INDIR" (for "indirect"), which
is to be used to represent indirect syscalls like syscall() and
__syscall() which are implemented in MD code and which don't want
args structures defined. (The old way of declaring this type of
syscalls still works.)
* Allow system calls to be marked as having a variable number of
arguments, by inserting "..." (no trailing comma) before the
first hf the optional arguments in the syscall definition. Because
of the way syscall arguments are handled by MI code, _ALL_ syscall
arguments must actually be included in the definition, i.e.
"optional" arguments are either "are there or aren't," i.e. these
aren't really varargs functions. Therefore, for normal syscalls,
there _must_ be arguments listed after the "...". For INDIR
syscalls, which really do have a variable number of arguments and
which aren't handled via the normal mechanism, that requirement is
not in force.
* output primitive (machine-parsable) syscall descriptions as comments
in <sys/syscall.h>. These can be used to easily build real function
prototypes, or to build stub functions for use by lint.
- Always allow RAW_PART to be opened, regardless of the partition table.
- Never do partition translation on RAW_PART; it's always offset 0.
- Always make sure the disklabel is read from RAW_PART.
- Make *strategy() return values consistent.
This fixes a condition where a bogus partition table could be written
to the disk from SYS_INST, and the user had no way to rewrite with
a correct partition table, since RAW_PART would be invalid.
bit from the extended setup inquiry and key off it to:
- Force synchronous negotiation on targs > 7.
- Read additional information returned by wide cards on inquire setup.
- Read sync period on targs > 7.
- Display sync period/offset on targs > 7.
- Set scsi_link.max_target to 15.
