mycroft 895de56d08 Fix recent bug in sys_accept(): we must remove the file descriptor from the
file descriptor table before freeing the file description.

enami 781f26d383 back out unnecessary stylistic changes in recent changes, to keep coding
style closer to NKF.

jdolecek 37c00e7548 minor cleanup of previous - avoid goto and code duplication 1999-10-27 13:17:46 +00:00
darrenr d2c8da2c36 patch from Greg A. Woods to fix panic problems with code that attempts to
recover from failures to accept a socket successfully.  Problem suggested
by this:
> It would appear (from two "panic: closef: count < 0" failures in less
> than 12 hours) that Darren's fix to accept(2) for lost file descriptors
> isn't quite correct.  His fix inserts a call to closef() to handle one
> of several possible error conditions.  However everywhere else in the
> socket code in the same file where falloc() cleanup is necessary the
> function used is ffree().

itojun 118d2b1d4f IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.

darrenr cd92b615fa fix sys_accept() to return EOPNOTSUPP for protocols which don't support
listen/accept (PR_LISTEN flag in protosw) and detect obvious faults in
parameters passed.  It is still possible for the address used for copying
the socket information to become invalid between that check and the copyout
so close the connection's allocated fd if the copyout fails so that we can
return EFAULT without allocating an fd and the application not knowing about
it.  Ideally we'd be able to queue the connection back up so a later accept
could retrieve it but unfortunately that's not possible.

thorpej e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.

cgd ee94a4dacb add checks for COMPAT_OSF1 in the appropriate places 1999-04-30 05:29:20 +00:00
kleink dfffb2f357 * Due to addition and use of socklen_t, make the socket option and address
arguments passed to accept(), bind(), connect(), getpeername(), getsockname(),
getsockopt(), recvfrom(), sendto() and sendmsg() unsigned, which also elimiates
a few casts.
* Reflect the (now) signedness of msg_iovlen, which necessiates the addition
of a few casts.
1999-02-10 18:02:28 +00:00
drochner c22ef79250 solve the COMPAT_OLDSOCK/MSG_COMPAT problem differently:
The source files which need MSG_COMPAT define COMPAT_OLDSOCK.
1998-12-18 13:18:42 +00:00
mycroft 74ad07cef5 Revert the functional change in rev 1.38; permit a msg_iovlen of 0.
There are two reasons for this:
* We should be able to pass file descriptors without sending any data.
* We could send zero-length iovecs anyway (but we shouldn't have to do this).
Also, msg_iovlen is already a u_int, so delete a bunch of casts.
1998-11-26 02:25:20 +00:00
kleink 7b07ad780a Per XNS Issue 5, calling recvmsg(2) or sendmsg(2) with an msg.msg_iovlen less
than or equal to 0 shall fail with EMSGSIZE; the latter condition was not being
checked for.  Also, document the msg.msg_iovlen > {IOV_MAX} case.

perry 275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)
1998-08-04 04:03:10 +00:00
kleink 3d9b4a4320 Fix two off-by-one bugs, both present in each recvmsg(2) and sendmsg(2):
* the first one would cause an unnecessary malloc() of iovec storage for
  a msg_iovlen of UIO_SMALLIOV although the required amount of memory has
  been allocated on the stack.
* the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of
  UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.

perry 730baa7431 fix sizeofs so they comply with the KNF style guide. yes, it is pedantic. 1998-07-31 22:50:48 +00:00
thorpej 4b039671de When checking for overflow in the residual count, test against SSIZE_MAX.
The read/write system calls return ssize_t because -1 is used to indicate
error, therefore the transfer size MUST be limited to SSIZE_MAX, otherwise
garbage can be returned to the user.

There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where
the full SSIZE_MAX transfer size can now be realized (ssize_t is 64-bit
on the Alpha).

thorpej 8dd0293cd3 Use UCHAR_MAX rather than "255" when sanity-checking the length of a
sockaddr in sockargs().
1997-06-26 06:13:36 +00:00
thorpej e1fb68eb29 In sockargs():
- Add a comment describing my feelings about this interface, in general.
- Remove the COMPAT_OLDSOCK length hack.  Instead, if the socket argument
  is too long to fit in an mbuf, allocate enough external storage to
  hold it.
- If the socket argument is a sockaddr, don't allow the length to be
  greater than 255, as that would overflow sa_len.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for his sanity checking.

cgd c60b7587ab * catch up with system call argument type fixups/const poisoning.
* Fix arguments to various copyin()/copyout() invocations, to avoid

* Some KNF formatting fixes
