to the controller. This is compatible with the linux and FreeBSD
implementations.
Add the needed conversion for mfi ioctls in COMPAT_LINUX
Allocate a character major number, and create /dev/mfi0 by default
on amd64 and i386.
This allows (along with a hand-created /emul/linux/proc/devices file)
to run the MegaCLI linux binary provided by LSI.
Contrary to the AMD implementation, it doesn't use xcalls to distribute
the update to all CPUs but relies on cpuctl(8) to bind itself to the
right CPU -- to keep it simple and avoid possible problems with
hyperthreading.
Also, it doesn't parse the vendor supplied file to pick the right
part for the present CPU model but relies on userland to prepare
files with specific filenames. I'll commit a pkg for this in a minute
(pkgsrc/sysutils/intel-microcode).
The ioctl interface changed; compatibility is provided (should be
limited to COMPAT_NETBSD6 as soon as this is available).
Add an MDL_COMPAT32 flag to the lwp's md_flags, set it for 32bit lwps
and use it to force 'return to user' with iret (as is done when
MDL_IRET is set).
Split the iret/sysret code paths much later.
Remove all the replicated code for 32bit system calls - which was only
needed so that iret was always used.
frameasm.h for XEN contains '#define swapgs', while XEN probable never
needs swapgs, this is likely to be confusing.
Add a SWAPGS which is a nop on XEN and swapgs otherwise.
(I've not yet checked all the swapgs in files that include frameasm.h)
Simple x86 programs still work.
Hijack 6.99.9 kernel bump (needed for compat32 modules)
assertion failure (and thus a crash in DIAGNOSTIC kernels). Independently
discovered by YAMAMOTO Takashi and Joel Sing.
To avoid this, introduce a cpu_mcontext_validate() function and move all
sanity checks from cpu_setmcontext() there. Also untangle the netbsd32
compat mess slightly and add a cpu_mcontext32_validate() cousin there.
Add an exhaustive atf test case, based partly on code from Joel Sing.
Should finally fix the remaining open part of PR kern/43903.
It is wishful thinking that:
1. declaring a 32 bit syscall with 64 bit pointers
2. passing a struct with 32 bit pointers to a 64 bit function
is going to work.
- Remove copy-pasting in error paths, use execve_free_{vmspace,data}().
- Move some code (both in the init and exit paths) out of the locks.
- Slightly simplify do_posix_spawn() callers.
- Add few asserts and comments.
- always provide a vmspace for the new proc, initially borrowing from proc0
(this part fixes PR 46286)
- increase parallelism between parent and child if arguments allow this,
avoiding a potential deadlock on exec_lock
- add a new flag for userland to request old (lockstepped) behaviour for
better error reporting
- adapt test cases to the previous two and add a new variant to test the
diagnostics flag
- fix a few memory (and lock) leaks
- provide netbsd32 compat
(exec_free_emul_arg) to call the hook and then clear the ep_emul_arg
and ep_emul_arg_free members in the exec_package.
Change users/accessors to use these routines.

unsigned. They are signed. (While unsigned might have been a better
choice, it doesn't really matter and the majority of preexisting uses
were signed. And consistency is good.)
- struct vfs_quotactl_args -> struct quotactl_args
- add sys/stdint.h to sys/quotactl.h for clean userland build
- install sys/quotactl.h in /usr/include
- update set lists for same
- add new marshalling code in libquota
- add new unmarshalling code in vfs_syscalls.c
- discard proplib interpreter code in vfs_quotactl.c
- add dispatching code for the 14 quotactl ops in vfs_quotactl.c
- mark the proplib quotactl syscall obsolete
- add a new syscall number for the new quotactl syscall
- change the name of the syscall to __quotactl()
- remove the decl of the old quotactl from quota/quotaprop.h
- add a decl of the new quotactl to sys/quotactl.h
- update the libc build
- update ktruss
- remove proplib marshalling code from libquota
- update copy of syscall table in gdb ppc sources
- hack rumphijack to accomodate new quotactl name (as I recall,
pooka wanted such a name change to simplify something, but I
don't really see what/how)
This change appears to require a kernel version bump for rumpish
reasons.
ufsclass2qtype -> quota_idtype_to_ufs
qtype2ufsclass -> quota_idtype_from_ufs
The reason for the direction of "ufs" changing is that the old names
were among the symbols using "ufs" to mean "fs-independent". So the
old names were for translating "ufsclass" (fs-independent quota id
type) to "qtype" (ufs-specific quota id type) and vice versa.
These functions are used in only two places, both of which are
inappropriate, so at some point they should probably be removed.
They're also identity transformations so not particularly helpful,
unless one were to make a careful and concerted effort to distinguish
the ufs quota code numbers from the fs-independent ones. This has not
been done and is probably impossible without support from a program
verifier, and maybe not even then.
They are static inline, so no compat concerns arise.
Also adjust the symbols they use to avoid <quota/quotaprop.h>.
and pass in two single quotaval structs (for blocks and inodes)
instead of an array of (implicitly) QUOTA_NLIMITS quotaval structs
indexed by constants from quotaprop.h.
Note: because this code is used by COMPAT_50 as well as ufs, this
change requires a kernel version bump. (The code is also used by
edquota, but via .PATH so it's not ABI-sensitive there.)
again. This was changed in sys/socket.h r1.51 to work around fallout
from the IPv6 aux data migration. It broke the historic ABI on some
platforms. This commit restores compatibility for netbsd32 code on such
platforms and provides a template for future changes to the CMSG_*
alignment. Revert PCC/Clang workarounds in postfix and tmux.
call its d_ioctl function. This should fix an undefined reference to
`clockctlioctl' when you build a kernel that has COMPAT_50 but does not
have pseudo-device clockctl.
When time_t was changed from 32 to 64 bits, this ioctl's number
was changed from _IOWR('C', 0x4, struct clockctl_ntp_adjtime)
to _IOWR('C', 0x8, struct clockctl_ntp_adjtime), but the data
structure did not change, so all the compat code has to do is
change the number and try again.
- Introduce MSG_NBIO so that we can turn non blocking i/o on a per call basis
- Use MSG_NBIO to fix the XXX: multi-threaded issues on the fifo sockets.
- Don't set SO_CANTRCVMORE, if we were interrupted (perhaps do it for all
errors?).
ioctl commands.
Tested with "rndctl -ls" using an old 32-bit version of rndctl(8)
(built for NetBSD-5.99.56/i386) and a new 64-bit kernel
(NetBSD-5.99.59/amd64).
it should be:
- stuff for the proplib interface goes in <quota/quotaprop.h>
- stuff for userlevel only goes in <quota/quota.h>
- stuff shared between user and kernel goes in <sys/quota.h>
Note that <quota/quota.h> and <quota/quotaprop.h> are expected to be
moved or removed later on... one thing at a time.
Update include directives in other files as needed.
no longer get it via sys/ucred.h and don't already include it
explicitly. These should in turn be removed when it can be confirmed
that it's safe to do so. (Because sys/param.h is full of things that
are often tested with #if, it's not in general safe to remove it
without checking, as such tests fail silently if the symbol goes
missing.)
returned to userland by read(2) also needs to be converted.
For this, the bpf descriptor is flagged as compat32 (or not) in the
open and ioctl functions (where the user process's pid is also updated
in the descriptor). When the bpf buffer is filled in, the 32bits or native
header is used depending on the information stored in the descriptor.
This won't work if a 64bit binary does the open and ioctls, and then
exec a 32bit program which will do the read. But this is very
unlikely to happen in real life ...
Tested on i386 and loongson; with these changes my loongson can run
dhclient and tcpdump with a n32 userland.

the effect of this is that termio linux apps won't have VEOF support.

- Add F_DUPFD_CLOEXEC to fcntl(2).
- Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing.
- Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
- Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
- Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter
for socket(2) and socketpair(2).
- Add new paccept(2) syscall that takes an additional sigset_t to alter
the sigmask temporarily and a flags argument to set SOCK_CLOEXEC,
SOCK_NONBLOCK.
- Add new mode character 'e' to fopen(3) and popen(3) to open pipes
and file descriptors for close on exec.
- Add new kqueue1(2) syscall with a new flags argument to open the
kqueue file descriptor with O_CLOEXEC, O_NONBLOCK.
* Fix the system calls that take socklen_t arguments to actually do so.
* Don't include userland header files (signal.h) from system header files
(rump_syscallargs.h).
* Bump libc version for the new syscalls.
parse quota plists; as well as a getfsquota() function to retrieve quotas
for a single id from a single filesystem (whatever filesystem this is:
a local quota-enabled fs or NFS). This is build on functions getufsquota()
(for local filesystems with UFS-like quotas) and getnfsquota();
which are also available to userland programs.
move functions from quota2_subr.c to libquota or libprop as appropriate,
and ajust in-tree quota tools.
move some declarations from kernel headers to either sys/quota.h or
quota/quota.h as appropriate. ufs/ufs/quota.h still installed because
it's needed by other installed ufs headers.
ufs/ufs/quota1.h still installed as a quick&dirty way to get a code
using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of
ufs/ufs/quota.h - old code won't compile without this change and this is
on purpose).
Discussed on tech-kern@ and tech-net@ (long thread, but not much about

same for both IPL32 and LP64 platforms.
pathbuf object passed to namei as work space instead. (For now a pnbuf

This removes the need for the SAVENAME and HASBUF namei flags.
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.

- update the linux syscall table for each platform.
- support new-style (NPTL) linux pthreads on all platforms.
clone() with CLONE_THREAD uses 1 process with many LWPs
instead of separate processes.
- move the contents of sys__lwp_setprivate() into a new
lwp_setprivate() and use that everywhere.
- update linux_release[] and linux32_release[] to "2.6.18".
- adjust placement of emul fork/exec/exit hooks as needed
and adjust other emul code to match.
- convert all struct emul definitions to use named initializers.
- change the pid allocator to allow multiple pids to refer to the same proc.
- remove a few fields from struct proc that are no longer needed.
- disable the non-functional "vdso" code in linux32/amd64,
glibc works fine without it.
- fix a race in the futex code where we could miss a wakeup after
a requeue operation.
- redo futex locking to be a little more efficient.
Rename real routines to proc_find() and pgrp_find(), remove PFIND_* flags
and have consistent behaviour. Provide proc_find_raw() for special cases.
Fix memory leak in sysctl_proc_corename().
COMPAT_LINUX: rework ptrace() locking, minimise differences between

things: passing an argument to check_exec, which is better done explicitly,
and handing back the resolved pathname generated by namei, which we can
make an explicit slot for in struct exec_package instead. While here,
perform some related tidyup, and store the kernel-side copy of the path
to the executable as well as the pointer into userspace. (But the latter
should probably be removed in the future.)
bus_space_tag. For now, bus_space_tag's only member is
bst_type, the type of space, which is either X86_BUS_SPACE_IO
or X86_BUS_SPACE_MEM. In the future, new bus_space_tag members
will refer to override-functions installed by a new function,
bus_space_tag_create(9).
Add pointers to constant struct bus_space_tag, x86_bus_space_io and
x86_bus_space_mem. Use them to replace most uses of X86_BUS_SPACE_IO
and X86_BUS_SPACE_MEM.
Add an x86-specific bus_space_is_equal(9) implementation that compares
the two tags' bst_type.

Also, same fix in osf1_sys_sendmsg_xopen().

- Plug a memory leak in compat_43_netbsd32_orecvmsg().
per-page execution right was disabled (therefore leading to the inability
of the kernel to detect fraudulent use of memory mappings marked as not
being executable).
- replace cpu_feature and ci_feature_flags variables by cpu_feature and
ci_feat_val arrays. This makes it cleaner and brings kernel code closer
to the design of cpuctl(8). A warning will be raised for each CPU that
does not expose the same features as the Boot Processor (BP).
- the blacklist of CPU features is now a macro defined in the
specialreg.h header, instead of hardcoding it inside MD initialization
code; fix comments.
- replace checks against CPUID_TSC with the cpu_hascounter() function.
- clean up the code in init_x86_64(), as cpu_feature variables are set
inside cpu_probe().
- use cpu_init_msrs() for i386. It will be eventually used later for NX
feature under i386 PAE kernels.
- remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already
performed by cpu_hatch() through cpu_init_msrs().
- remove cpu_signature and feature_flags members from struct mpbios_proc
(they were never used).
This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under
a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines.
XXX Should kernel rev be bumped?
XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.
