kml fc1ebff2b2 Large values of sb_max would cause an overflow in sbreserve(); cast to
u_quad_t to avoid this.  (from FreeBSD uipc_socket2.c v1.19)

itojun c47506aed1 more fix to ancillary data alignment. we need padding after
last cmsg_data item (see the figure on RFC2292 page 18).

itojun 83176f3b3c fix alignment problem in ancillary messages (alpha).
the change constitutes binary compatibility issue hen sizeof(long) !=4.
there's no way to be backward compatible, and only guys affected
are IPv6 userland tools.

mycroft f85ee5e22e The old compaction test had an off-by-one error that caused it to not compact
in some cases where it could have.  Fix this, and the new version as well.

matt 0dc0497a97 Don't compress mbuf clusters which are referenced by multiple
mbufs since you might overwriting valuable data.  (think of
m_copy'ed data from a TCP re-transmission queue.  Since those
might be in clusters and referenced in two sockets).
1999-08-04 21:40:39 +00:00
mycroft 545d8679c0 It's now possible for sbcompress() to compact mbuf clusters, so do it.
This helps prevent mbuf cluster exhaustion when receiving lots of small
packets.

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.

simonb 8ce41be7b0 Move inclusion of "opt_sb_max.h" from sys/socketvar.h to
conf/param.c, and move the initialisation of the sb_max
variable from kern/uipc_socket2.c to conf/param.c.  Now
everthing that includes sys/socketvar.h doesn't get
recompiled when SB_MAX's value changes.

lukem 8a931fcdd8 Ensure that you can only bind a more specific address when it is done by the
same uid or by root.

This code is from FreeBSD. (Whilst it was originally obtained from OpenBSD,
FreeBSD fixed it to work with multicast. To quote the commit message:
    - Don't bother checking for conflicting sockets if we're binding to a
      multicast address.
    - Don't return an error if we're binding to INADDR_ANY, the conflicting
      socket is bound to INADDR_ANY, and the conflicting socket has
      SO_REUSEPORT set.

thorpej f8ae3272b9 Back out previous soqinsque() and soqremque() changes. This will
stop the panics until the socket queues get converted to <sys/queue.h>.
1996-11-26 23:24:04 +00:00
thorpej 26a25a87b2 Optimization of soqinsque() and soqremque():
Keep queue of pending sockets in a double linked list.  Previously,
a singly linked list was used, giving O(N) insertion/deletion times,
and was a major time consumer for sockets with large pending queues.
The double linked list give O(C) insertion/deletion times with only
a small cost in complexity.

Since a socket can be on, at most, one queue at a time, both so_q and
so_q0 can safely be used as (forward and backward, respectively) queue
pointers.

Submitted my Matt Thomas <matt@3am-software.com>, a long time ago.
(Geez, I've been running with this patch for _months_, and had completely
forgotten about it!)
