kamil | Avoid -LONG_MIN msgtyp in msgrcv(2) and treat it as LONG_MAX
This logic (found in Linux) avoids undefined behavior.

pgoyette | Many years ago someone created a new __link_set_sysctl_funcs to hold
the list of routines that need to be called for setting up sysctl
variables. This worked great for all code included in the kernel
itself, but didn't deal with modules that want to create their own
sysctl data. So, we ended up with a lot of #ifdef _MODULE blocks
so modules could explicitly call their setup functions when loaded
as non-built-in modules.
So today, we complete the task that was started so many years ago.
When modules are loaded, after we've called xxx_modcmd(INIT...) we
check if the module contains its own __link_set_sysctl_funcs, and
if so we call the functions listed. We add a struct sysctllog member
to the struct module so we can call sysctl_teardown() when the module
gets unloaded. (The sequence of events ensures that the sysctl stuff
doesn't get created until the rest of the module's init code does any
required memory allocation.)
So, no more need to explicitly call the sysctl setup routines when
built as a loadable module.

pgoyette | branches: 1.74.4;
Replace some "panic()" calls with simple "printf() ; return error"
There's no good reason for these build-time parameters to be allowed to
panic the kernel when it is easy to simply disable the module code and
fail gracefully.
While we're at it, similarly replace panic() when malloc fails to also
fail gracefully.

mrg | for sysv ipc stat operations, explicitly copy the exported parts
instead of the whole ds structure.
besides triggering a recently added assert in netbsd32, this stops
exposing kernel addresses.
copy the mode clamping to 0777 from sem to shm and msg.
while here, make sure that the compat callers to sysv_ipc clear
the contents of the compat structure before setting the result
members to ensure padding bytes are cleared.
don't set/copy _sem_base, _msg_first, _msg_last or _shm_internal.
even if used, which seems very dodgy, they leak KVAs as well.
possibly this may affect linux binaries, in particular, the
comments around _shm_internal ("XXX Oh well.") may mean apps
rely upon these but hopefully not -- the comments date back to
rev 1.1 in 1995.
the _key, _seq and _msg_cbytes members are exported as before as
i found multiple consumers of these (no less than ipcs(1), and
they appear to be useful for debugging and more.
XXX: the naming of compat functions have too many styles. there
are at least 3 different ones changed here.

pgoyette | In sysv_sem.c, defer establishment of exithook so we can initialize the
module code from module_init() rather than waiting until after calling
exec_init(). Use a RUN_ONCE routine at entry to each sys_sem* syscall
to establish the exithook, and no longer KASSERT that the hook has
been set before removing it. (A manually loaded module can be unloaded
before any syscalls have been invoked.)
Remove the conditional calls to the various xxx_init() routines from
init_main.c - we now rely on module_init() to handle initialization.
Let each sub-component's xxx_init() routine handle its own sysctl
sub-tree initialization; this removes another set of #ifdef ugliness.
Tested both built-in and loadable versions and verified that atf
test kernel/t_sysv passes.
|
| 1.69 |
| 13-May-2015 |
pgoyette | More prep: add a xxxfini() routine to each subcomponent so we can
clean up after ourselves. Mostly, this checks to make sure that
there are no active itmes, and then deallocates wired kernel virtual
memory. For SYSVSEM, we also disestablish the exithook() so we
won't try to call it after destroying its memory pool!
|
| 1.68 |
| 13-May-2015 |
pgoyette | More preparation for modularizing the SYSVxxx options. Here we
change the kern.ipc.sysvxxx sysctls into dynamic values, so each
sub-component of SYSVxxx can declare its own availability.

Patch up sysctl locking:
- Lock processes, credentials, filehead etc correctly.
- Acquire a read hold on sysctl_treelock if only doing a query.
- Don't wire down the output buffer. It doesn't work correctly and the code
regularly does long term sleeps with it held - it's not worth it.
- Don't hold locks other than sysctl_lock while doing copyout().
- Drop sysctl_lock while doing copyout / allocating memory in a few places.
- Don't take kernel_lock for sysctl.
- Fix a number of bugs spotted along the way

dsl | Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

| 1.56.2.2 |
| 14-May-2008 |
wrstuden | Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.
Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)
Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.
This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.
I think this reduction is very good thing.

wrstuden | Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.
Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

for sysv ipc stat operations, explicitly copy the exported parts

besides triggering a recently added assert in netbsd32, this stops
exposing kernel addresses.
copy the mode clamping to 0777 from sem to shm and msg.
while here, make sure that the compat callers to sysv_ipc clear
the contents of the compat structure before setting the result
members to ensure padding bytes are cleared.
don't set/copy _sem_base, _msg_first, _msg_last or _shm_internal.
even if used, which seems very dodgy, they leak KVAs as well.
possibly this may affect linux binaries, in particular, the
comments around _shm_internal ("XXX Oh well.") may mean apps
rely upon these but hopefully not -- the comments date back to
rev 1.1 in 1995.
the _key, _seq and _msg_cbytes members are exported as before as
i found multiple consumers of these (no less than ipcs(1), and
they appear to be useful for debugging and more.
XXX: the naming of compat functions have too many styles. there
are at least 3 different ones changed here.
fix naming errors in previous. (this file is no longer compiled, but
this fix makes the pull up more obvious, before deleting this file.)
include libkern.h or strings.h. should fix i386 build issues.
