riastradh | compat_30: Fix thinko in previous.
Let's not go into an infinite loop of stack smashing!

riastradh | compat_30: Avoid what might be technically undefined behaviour.
Not sure advancing a user pointer by one for the purpose of making an
equality test fail later on is actually likely to be a problem, but
let's just pacify the sanitizer.

riastradh | sys/compat: Memset zero before copyout.
Just in case of uninitialized padding which would lead to kernel
stack disclosure. If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

christos | - memset struct stat to avoid kernel memory disclosure of padded fields
(thanks Trend Micro for the report)

riastradh | Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.
To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

dholland | branches: 1.33.18; 1.33.34;
Introduce struct pathbuf. This is an abstraction to hold a pathname
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.
Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).
The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

he | branches: 1.31.2;
When implementing "read directory", when there are too many empty entries
in a row, and we need to try to read the next block, and have passed a
non-NULL cookie pointer to VOP_READDIR, ensure that we free the cookie
buffer before re-doing VOP_READDIR, so that we don't leak memory.
This fix is similar to nfs_serv.c revisions 1.115 + 1.124.
This should fix the long-standing problem observed by e.g. using Linux-
emulated programs to take backup of servers, which is one of the problems
which were reported in PR#42661.

Convert all the system call entry points from:

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).
98% done by automated scripts.

Remove cn_lwp from struct componentname. curlwp should be used

dsl | branches: 1.23.6; 1.23.8; 1.23.16;
Split the statvfs functions so that the 'work' is done to a kernel buffer
which can either be copied directly to userspace, or converted then copied.
Saves replicating a lot of code in the compat functions (esp. for
getvfsstat) at a cast of an extra function call in the non-emulated case -
which is unlikely to be measurable given the other costs of the actions
involved (even on vax).
Remove dofhstat() and dofhstatvfs() (and the last caller).
Remove some redundant stackgap_init() calls.
|
| 1.22 |
| 22-Apr-2007 |
dsl | Change the way that emulations locate files within the emulation root to
avoid having to allocate space in the 'stackgap'
- which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
search for absolute pathnames in the emulation root, if that fails it will
retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
the real root is returned instead (matching the behaviour of emul_lookup,
but being a cheap comparison here) so that programs that scan "../.."
looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.

yamt | some filehandle syscall related changes.
- remove the support of variable-sized filehandle from compat version of
syscalls. (strictly speaking, it breaks abi. i don't think it's a problem
because this feature is short-lived and there are no affected in-tree
filesystems.)
- unify vfs_copyinfh_alloc and vfs_copyinfh_alloc_size.
- vfs_copyinfh_alloc_size: check fhsize strictly.
- reduce code duplication between compat and current syscalls.

| 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.
