chs | When SS_RESTARTSYS was added, it was accidentally given the same value as
the existing SS_ASYNC. SS_ASYNC was already vestigial at that point,
having been superceded by SB_ASYNC, however the SS_ASYNC flag is still
set and cleared, unlessly because it is never checked.
Fix this conflict by removing SS_ASYNC and its vestigial uses.

dsl | If a multithreaded app closes an fd while another thread is blocked in
read/write/accept, then the expectation is that the blocked thread will
exit and the close complete.
Since only one fd is affected, but many fd can refer to the same file,
the close code can only request the fs code unblock with ERESTART.
Fixed for pipes and sockets, ERESTART will only be generated after such
a close - so there should be no change for other programs.
Also rename fo_abort() to fo_restart() (this used to be fo_drain()).
Fixes PR/26567

dsl | Rename fo_drain() to fo_abort(), 'drain' is used to mean 'wait for output
do drain' in many places, whereas fo_drain() was called in order to force

call from a different thread can complete.

it was being called from compat code.

wrstuden | Add support for FIONWRITE and FIONSPACE ioctls. FIONWRITE reports
the number of bytes in the send queue, and FIONSPACE reports the
number of free bytes in the send queue. These ioctls permit applications
to monitor file descriptor transmission dynamics.
In examining prior art, FIONWRITE exists with the semantics given
here. FIONSPACE is provided so that programs may easily determine how
much space is left in the send queue; they do not need to know the
send queue size.
The fact that a write may block even if there is enough space in the
send queue for it is noted in the documentation.
FIONWRITE functionality may be used to implement TIOCOUTQ for Linux
emulation - Linux extended this ioctl to sockets, even though they are
not ttys.

jonathan | Eliminate several uses of `curproc' from the socket-layer code and from NFS.
Add a new explicit `struct proc *p' argument to socreate(), sosend().
Use that argument instead of curproc. Follow-on changes to pass that
argument to socreate(), sosend(), and (*so->so_send)() calls.
These changes reviewed and independently recoded by Matt Thomas.
Changes to soreceive() and (*dom->dom_exernalize() from Matt Thomas:
pass soreceive()'s struct uio* uio->uio_procp to unp_externalize().
Eliminate curproc from unp_externalize. Also, now soreceive() uses
its uio->uio_procp value, pass that same value downward to
((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.
Similar changes in sys/nfs to eliminate (most) uses of curproc,
either via the req-> r_procp field of a struct nfsreq *req argument,
or by passing down new explicit struct proc * arguments.
Reviewed by: Matt Thomas, posted to tech-kern.
NB: The (*pr->pru_usrreq)() change should be tested on more (all!) protocols.

Use SB_ASYNC in struct sockbuf sb_flags field instead of SS_ASYNC in
struct socket so_state field to decide if we need to send asynchronous
notifications. This makes possible to request notification on write but
not on read, and vice versa.
This is used in Linux emulation code, because when async I/O is requested,
Linux does not send SIGIO to write end of sockets, and it never send any
SIGIO to any end of pipes. Il Linux emulation code, we then set SB_ASYNC
only on the read end of sockets, and on no end for pipes.

EMUL_BSD_ASYNCIO_PIPE notes that the emulated binaries expect the original
BSD pipe behavior for asynchronous I/O, which is to fire SIGIO on read() and
write(). OSes without this flag do not expect any SIGIO to be fired on
read() and write() for pipes, even when async I/O was requested. As far as
we know, the OSes that need EMUL_BSD_ASYNCIO_PIPE are NetBSD, OSF/1 and
Darwin.

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for
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.

Add fileops::fo_drain(), to be called from fd_close() when there is more
than one active reference to a file descriptor. It should dislodge threads
sleeping while holding a reference to the descriptor. Implemented only for
sockets but should be extended to pipes, fifos, etc.
Fixes the case of a multithreaded process doing something like the
following, which would have hung until the process got a signal.
thr0 accept(fd, ...)
thr1 close(fd)

methods: pr_attach, pr_detach and pr_generic for old the pr_usrreq.
- Adjust socreate(9) and sonewconn(9) to call pr_attach without the
socket lock held (as a preparation for the locking scheme adjustment).
- Adjust all pr_attach routines to assert that PCB is not set.
- Sprinkle various comments, document some routines and their locking.
- Remove M_PCB, replace with kmem(9).
- Fix few bugs spotted on the way.

the underlying pools are the same but api-wise those should match
Unify IFEF_*_MPSAFE into IFEF_MPSAFE
There are already two flags for if_output and if_start, however, it seems such
MPSAFE flags are eventually needed for all if_XXX operations. Having discrete
flags for each operation is wasteful of if_extflags bits. So let's unify
the flags into one: IFEF_MPSAFE.
Fortunately IFEF_*_MPSAFE flags have never been included in any releases, so
we can change them without breaking backward compatibility of the releases
(though the kernel version of -current should be bumped).
Note that if an interface have both MP-safe and non-MP-safe operations at a
time, we have to set the IFEF_MPSAFE flag and let callees of non-MP-safe
opeartions take the kernel lock.
Proposed on tech-kern@ and tech-net@
Provide macros for softnet_lock and KERNEL_LOCK hiding NET_MPSAFE switch
It reduces C&P codes such as "#ifndef NET_MPSAFE KERNEL_LOCK(1, NULL); ..."
scattered all over the source code and makes it easy to identify remaining
KERNEL_LOCK and/or softnet_lock that are held even if NET_MPSAFE.
No functional change
Hold KERNEL_LOCK on if_ioctl selectively based on IFEF_MPSAFE
If IFEF_MPSAFE is set, hold the lock and otherwise don't hold.
This change requires additions of KERNEL_LOCK to subsequence functions from
if_ioctl such as ifmedia_ioctl and ifioctl_common to protect non-MP-safe
components.
Proposed on tech-kern@ and tech-net@
Ensure to hold if_ioctl_lock when calling if_flags_set
Fix locking against myself on ifpromisc
vlan_unconfig_locked could be called with holding if_ioctl_lock.
Ensure to not turn on IFF_RUNNING of an interface until its initialization completes
And ensure to turn off it before destruction as per IFF_RUNNING's description
"resource allocated". (The description is a bit doubtful though, I believe the
change is still proper.)
Ensure to hold if_ioctl_lock on if_up and if_down
One exception for if_down is if_detach; in the case the lock isn't needed
because it's guaranteed that no other one can access ifp at that point.
Make if_link_queue MP-safe if IFEF_MPSAFE
if_link_queue is a queue to store events of link state changes, which is
used to pass events from (typically) an interrupt handler to
if_link_state_change softint. The queue was protected by KERNEL_LOCK so far,
but if IFEF_MPSAFE is enabled, it becomes unsafe because (perhaps) an interrupt
handler of an interface with IFEF_MPSAFE doesn't take KERNEL_LOCK. Protect it
by a spin mutex.
Additionally with this change KERNEL_LOCK of if_link_state_change softint is
omitted if NET_MPSAFE is enabled.
Note that the spin mutex is now ifp->if_snd.ifq_lock as well as the case of
if_timer (see the comment).
Use IFADDR_WRITER_FOREACH instead of IFADDR_READER_FOREACH
At that point no other one modifies the list so IFADDR_READER_FOREACH
is unnecessary. Use of IFADDR_READER_FOREACH is harmless in general though,
if we try to detect contract violations of pserialize, using it violates
the contract. So avoid using it makes life easy.
Ensure to call if_addr_init with holding if_ioctl_lock
Get rid of outdated comments
Fix build of kernels without ether
By throwing out if_enable_vlan_mtu and if_disable_vlan_mtu that
created a unnecessary dependency from if.c to if_ethersubr.c.
PR kern/52790
Rename IFNET_LOCK to IFNET_GLOBAL_LOCK
IFNET_LOCK will be used in another lock, if_ioctl_lock (might be renamed then).
Wrap if_ioctl_lock with IFNET_* macros (NFC)
Also if_ioctl_lock perhaps needs to be renamed to something because it's now
not just for ioctl...
Reorder some destruction routines in if_detach
- Destroy if_ioctl_lock at the end of the if_detach because it's used in various
destruction routines
- Move psref_target_destroy after pr_purgeif because we want to use psref in
pr_purgeif (otherwise destruction procedures can be tricky)
Ensure to call if_mcast_op with holding IFNET_LOCK
Note that CARP doesn't deal with IFNET_LOCK yet.
Remove IFNET_GLOBAL_LOCK where it's unnecessary because IFNET_LOCK is held
Describe which lock is used to protect each member variable of struct ifnet
Requested by skrll@
Write a guideline for converting an interface to IFEF_MPSAFE
Requested by skrll@
Note that IFNET_LOCK must not be held in softint
Don't set IFEF_MPSAFE unless NET_MPSAFE at this point
Because recent investigations show that interfaces with IFEF_MPSAFE need to
follow additional restrictions to work with the flag safely. We should enable it
on an interface by default only if the interface surely satisfies the
restrictions, which are described in if.h.
Note that enabling IFEF_MPSAFE solely gains a few benefit on performance because
the network stack is still serialized by the big kernel locks by default.
