socket: report receive buffer overflows

Add soroverflow() which increments the overflow counter, sets so_error
to ENOBUFS and wakes the receive socket up.
Replace all code that manually increments this counter with soroverflow().
Add soroverflow() to raw_input().

This allows userland to detect route(4) overflows so it can re-sync
with the current state.

* change pr_bind to accept struct sockaddr * instead of struct mbuf *
* update protocol bind implementations to use/expect sockaddr *
  instead of mbuf *
* introduce sockaddr_big struct for storage of addr data passed via
  sys_bind; sockaddr_big is of sufficient size and alignment to
  accommodate all addr data sizes received.
* modify sys_bind to allocate sockaddr_big instead of using an mbuf.
* bump kernel version to 7.99.9 for change to pr_bind() parameter type.

Patch posted to tech-net@
  http://mail-index.netbsd.org/tech-net/2015/03/15/msg005004.html

The choice to use a new structure sockaddr_big has been retained since
changing sockaddr_storage size would lead to unnecessary ABI change. The
use of the new structure does not preclude future work that increases
the size of sockaddr_storage and at that time sockaddr_big may be
trivially replaced.

Tested by mrg@ and myself, discussed with rmind@, posted to tech-net@

Handle LOCAL_PEERID for socketpair() connected sockets which connect through
connect2().
1. move the code that sets the peerid structure into connect1(). This
   handles so2.  The datagram code calls connect2 twice with flipped
   so arguments so both sockets get set.
2. in connect2 copy the peerid structure from so2 to so, so that that
   both stream sockets get set.

* replace calls using pr_generic with req == PRU_SENSE with pr_stat().

further change will follow that cleans up the pattern used to extract the

param4 changed to struct ifnet * and uses parameter name 'ifp'
param5 has been removed (formerly struct lwp *) and uses of 'l' have been
       replaced with curlwp from curproc(9).

callers have had (now unnecessary) casts to struct mbuf * removed, called
code has had (now unnecessary) casts to u_long, void * and struct ifnet *

Avoid crash dereferencing a NULL fp in fd_affix() in unp_externalize
caused by the sequence of passing two fd's with two sendmsg()'s,
then doing a read() and a recvmsg(). The read() calls dom_dispose()
which discards both messages in the mbuf, and sets the fp's in the
array to NULL. Linux dequeues only one message per read() so the
second recvmsg() gets the fd from the second message.  This fix
just avoids the NULL pointer de-reference, making the second
recvmsg() to fail. It is dubious to pass fd's with stream sockets
and expect mixing read() and recvmsg() to work. Plus processing
one control message per read() changes the current semantics and
should be examined before applied. In addition there is a race between
dom_externalize() and dom_dispose(): what happens in a multi-threaded
network stack when one thread disposes where the other externalizes
the same array?

NB: Pullup to 6.

    - 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.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

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.

More changes to improve kern_descrip.c.

- Avoid atomics in more places.
- Remove the per-descriptor mutex, and just use filedesc_t::fd_lock.
  It was only being used to synchronize close, and in any case we needed
  to take fd_lock to free the descriptor slot.
- Optimize certain paths for the <NDFDFILE case.
- Sprinkle more comments and assertions.
- Cache more stuff in filedesc_t.
- Fix numerous minor bugs spotted along the way.
- Restructure how the open files array is maintained, for clarity and so
  that we can eliminate the membar_consumer() call in fd_getfile().  This is
  mostly syntactic sugar; the main functional change is that fd_nfiles now
  lives alongside the open file array.

Some measurements with libmicro:

- simple file syscalls are like close() are between 1 to 10% faster.
- some nice improvements, e.g. poll(1000) which is ~50% faster.

completely rework the way that orphaned sockets that are being fdpassed
via SCM_RIGHTS messages are dealt with:

1. unp_gc: make this a kthread.

2. unp_detach: go not call unp_gc directly. instead, wake up unp_gc kthread.

3. unp_scan: do not close files here. instead, put them on a global list
   for unp_gc to close, along with a per-file "deferred close count". if
   file is already enqueued for close, just increment deferred close count.
   this eliminates the recursive calls.

3. unp_gc: scan files on global deferred close list. close each file N
   times, as specified by deferred close count in file. continue processing
   list until it becomes empty (closing may cause additional files to be
   queued for close).

4. unp_gc: add additional bit to mark files we are scanning. set during
   initial scan of global file list that currently clears FMARK/FDEFER.
   during later scans, never examine / garbage collect descriptors that
   we have not marked during the earlier scan. do not proceed with this
   initial scan until all deferred closes have been processed. be careful
   with locking to ensure no races are introduced between deferred close
   and file scan.

5. unp_gc: use dummy file_t to mark position in list when scanning. allow
   us to drop filelist_lock. in turn allows us to eliminate kmem_alloc()
   and safely close files, etc.

6. prohibit transfer of descriptors within SCM_RIGHTS messages if
   (num_files_in_transit > maxfiles / unp_rights_ratio)

7. fd_allocfile: ensure recycled filse don't get scanned.


this is 97% work done by andrew doran, with a couple of minor bug fixes
and a lot of testing by yours truly.

There can be existing waiters on a socket's condition variables when we
change socket::so_lock, and they rely on the old lock to synchronize.
Wake them up whenever we change so_lock so they can restart their waits.

Merge the socket locking patch:

- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

When unp_internalize fails (due to the sanity check or an out-of-memory
condition), it leaves the control message with file descriptors. Calling
unp_dispose() will interpret the message as containing file pointers
and crash the system.
This change removes unp_dispose() from this failure path and avoids
using goto to jump into switch statements...
The previous workaround to ignore such messages in unp_scan() is removed.

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.

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

((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.

Similar changes in sys/nfs to eliminate (most) uses of curproc,

or by passing down new explicit struct proc * arguments.

Reviewed by: Matt Thomas, posted to tech-kern.

Avoid using m_clget() on a mbuf already in use, especially when we
need the data in the mbuf later and m_clget() changes some fields
overlaid to regular mbuf data. Instead, rearange code a bit, create
data into a new allocated buffer and and use MEXTADD to attach it to
the mbuf, if the mbuf internal space is not sufficient.

This fixes a crash on sparc64 (and probably all other archs where
sizeof(int) != sizeof(struct file *)) when running
regress/sys/kern/unfdpass.

Fix a partial construction problem that can cause race conditions
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

Rework fdalloc() even further: split fdalloc() into fdalloc() and
fdexpand().  The former will return ENOSPC if there is not space
in the current filedesc table.  The latter performs the expansion
of the filedesc table.  This means that fdalloc() won't ever block,
and it gives callers an opportunity to clean up before the
potentially-blocking fdexpand() call.

Update all fdalloc() callers to deal with the need-to-fdexpand() case.

Rewrite unp_externalize() to use fdalloc() and fdexpand() in a
safe way, using an algorithm suggested by Bill Sommerfeld:
- Use a temporary array of integers to hold the new filedesc table
  indexes.  This allows us to repeat the loop if necessary.
- Loop through the array of file *'s, assigning them to filedesc table
  slots.  If fdalloc() indicates expansion is necessary, undo the
  assignments we've done so far, expand, and retry the whole process.
- Once all file *'s have been assigned to slots, update the f_msgcount
  and unp_rights counters.
- Right before we return, copy the temporary integer array to the message
  buffer, and trim the length as before.
Note that once locking is added to the filedesc array, this entire
operation will be `atomic', in that the lock will be held while
file *'s are assigned to embryonic table slots, thus preventing anything
else from using them.

Change fdalloc() to return ERESTART if we had to reallocate the
descriptor array, which may have blocked.  Change callers of

happens.  (XXX unp_externalize() needs some work, but that will
be tackled later.)

Change finishdup() to close the descriptor in the `new\' slot if
one exists, and change sys_dup2() accordingly.

Closes a race condition when using kernel-assisted user threads.

While here, garbage-collect UF_MAPPED -- it is not used anywhere.

Disallow descriptor-passing of descriptors which are open on
directories which aren't under the recipient's root.

Clean up of many error conditions involving descriptor passing, to
eliminate infinite loops, panics, premature garbage collection of
sockets, and descriptor leaks:
 - Avoid letting unp_gc() see descriptors with a refcount of zero by
removing them from the socket's queue before releasing them.
 - Avoid socket leak in PRU_ABORT (this will also gc descriptors queued
on a not-yet accepted socket when the accepting socket goes away).
 - Put in block comment explaining how unp_gc() should work.
 - Correctly manage unp_defer count so we don't get stuck in an infinite
loop with nothing to do.
 - Don't tie MARK and DEFER bits so closely together.
 - Mark descriptors queued on not-yet-accepted sockets as well.
 - Don't call sorflush on non-socket, it doesn't work very well.
 - Deal with discard of NULL file pointer.
 - Hopefully cause GC to converge faster by only deferring sockets in
unp_mark().

Implement passing credentials as ancillary data on Unix domain sockets,
enabled with the LOCAL_CREDS socket option on the listener.  Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
  on SOCK_DGRAM.
- It is not possible to forge credentials.

Different in that:
- Different credential data structure (ours does not rely on the format
  of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
  work in BSD/OS).

Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this.  :-)
