ryo | - Add compat_linux statx(2) syscall.
- The AT_EMPTY_PATH processing from the modification of
sys/compat/linux/common/linux_file64.c r1.63 has been separated, and made
common to linux_statat(), so that it can be used not only by
linux32_sys_fstatat64() but also by other *statat() variants.

| 25-Nov-2021 |
ryo | rename bsd_to_linux_stat() to bsd_to_linux_stat64() to avoid confusion.
There is a static function with the same name in linux/common/linux_file.c.

rin | linux_sys_fstatat64: Add support for AT_EMPTY_PATH flag.
This is required for rtld shipped with glibc 2.33.
Now, userland of Fedora 34 is working fine on NetBSD/amd64.

riastradh | branches: 1.60.4;
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macppc/if_gm.c (superseded by gem(4))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!)

he | branches: 1.50.2;
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.
Thanks to pooka@ for the hints for traversing the VOP* layer.

Extract the fcntl64() suppoort from linux_file64.c into linux_fcntl64.c

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).

be used.

Split the fcntl locking code out from its copyin/out.
Use to avoid all the stackgap stuff in compat code.
|
| 1.38 |
| 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.

| 1.37 |
| 10-Mar-2007 |
dsl | branches: 1.37.2;
Update all the compat stuff to not use the 'stackgap' for processing
sys_stat() and friends, instead use do_sys_stat() and do_sys_fstat()
that write the answer into a kernel buffer (on stack) that can be
converted to the correct form and written the userspace.
I've test compiled a few kernels, and tested i386 netbsd1.6 ls.
Given I think I've fixed some bugs, it might be 50-50 with new ones.

others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

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.
Thanks to pooka@ for the hints for traversing the VOP* layer.

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

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.
|
| 1.47.2.1 |
| 10-May-2008 |
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.

Fix info leaks.
Fix stupid bugs in linux_sys_shmctl(): the index could be out of bound
(page fault) and there was no proper locking.
Maybe we should just remove LINUX_SHM_STAT, like compat_linux32.
Remove printf.
When dealing with an unknown value, set -1, to prevent (harmless)
uninitialized accesses later.
Add a default case, don't call sys_ioctl() with an uninitialized 'com'
argument.
Fix error handling, returns an errno, not -1.
Put the printf under DEBUG_LINUX.
Hum, don't forget the 'pid' argument, otherwise we're not gonna go very
far.
Don't read data from userland directly. This simply does not work on any
recent x86 CPU (thanks to SMAP) and all architectures that forbid direct
access to userland from the kernel. But I guess no one noticed because no
one ever uses compat_linux, right?
Hum, don't pass an mbuf to realloc(). Inspired from copyin32_msg_control().
Fix memory leak.
I don't see the point in having this useless printf, but add a '\n' to it,
so that it at least displays useless stuff correctly.
Hum, remove incorrect assignment. Userland could have passed a smaller
namelen, and the uninitialized bytes from sb_data were being used later in
the network stack.
