first, avoiding the cast to uio_resid (int in stdio)
from degrading the value.

dteske [Tue, 22 Jul 2014 23:10:12 +0000 (23:10 +0000)]
Add example script `add_some_packages.sh', demonstrating how to install
a list of packages using the bsdconfig(8) API, providing dialog(8) based
user experience (versus plain console output were you to use pkg(8)
directly to install the same list of packages).

Remove example script `browse_packages_ftp.sh', made obsolete because
the digests.txz and packagesite.txz databases for pkg(8) are not
available via FTP (HTTP only to pkg.freebsd.org SRV hosts).

Update example script `browse_packages_http.sh', made to work with new
pkg(8) demonstrating how to generate a local package repository.

Fix a bug in `bsdconfig packages' where packages were listed twice. This
fix requires pkg(8) version 1.2.7_4 or higher.

NB: It is the introduction of pkg(8) 1.2.7_4 wherein I am also able to
drastically reduce the generation time of package dependencies prior to
the dialog display (by utilizing the new `-I' flag to pkg-rquery(8)).

While here, fix a positional argument nit for f_index_initialize() of
`packages/index.subr' include (the one and only argument is positional
argument 1 to state the by-ref handle, indicating the variable to set
in the caller's namespace; the nit I'm fixing here is that we were
querying positional argument 2 for this information incorrectly; caused
by a missing hunk back around SVN r257795).

Fix a bug in sysrc(8) described by PR bin/187458 "sysrc(8) silently and
unexpectedly bootstraps pkg". This was caused by an explicit entry in
`/usr/share/bsdconfig/common.subr' (used by sysrc(8)) that called pkg(8)
to populate the $PKG_ABI global (called in a way that allows implicit
bootstrap of pkg(8)). The solution to which was to find every place in
bsdconfig(8) that requires the $PKG_ABI global and add a layer of
protection by way of introducing the new API call f_musthavepkg_init()
(provided by new include, `/usr/share/bsdconfig/packages/musthavepkg.subr'
intented to mirror `/usr/share/bsdconfig/mustberoot.subr'). When the
$PKG_ABI global is required, you can use `f_musthavepkg_init' to cause
graceful premature termination in the event that pkg(8) has not yet been
bootstrapped, and thus cannot be used to populate $PKG_ABI.

NB: If running interactively ($nonInteractive is NULL or unset), the
f_musthavepkg_init() API call will attempt to bootstrap pkg(8), but only
if the user chooses "Yes" to a Yes/No dialog confirming it is ok to
bootstrap.

While here, simplify an if-conditional in `media/http.subr' include to
use sh(1) inline assignment-with-break.

Also, fix a bug in `media/http.subr' and `media/httpproxy.subr' wherein
the error messages for various HTTP failures were not finding their way
to the console (needed to pass stdout to pass-thru descriptor).

While here, remove the executable bit from `packages/categories.subr',
`packages/index.subr', and `packages/packages.subr' includes.

Fix issues where pkg(8) complains about PACKAGESITE being defined.
Previously, we would set $PACKAGESITE and export it. Now we only set
$PACKAGESITE for invocations of "pkg update" -- getting rid of all the
spurious warnings about PACKAGESITE being deprecated (it's still used
in the case of "pkg update" for simplicity versus having to configure
a config-file).

Remove the leading argument from invocations of f_index_initialize() in
`packages/packages.subr' include. The leading argument no longer means
what it used to, pre SVN r257995).

for either IPv4 and IPv6.

The specifics:

* The UDP init path udp_init() and udplite_init() specify the hash as
  2-tuple, so the PCBGROUPS code only tries a 2-tuple check;
* The PCBGROUPS and RSS code doesn't know about the UDP hash types
  just yet, so they're never treated as valid hashes.
* For correctness, 4-tuple can't be enabled in the general case because
  UDP datagrams can be more fragmented than IP datagrams may be.

Strictly speaking, TCP datagrams may also be fragmented and this could
cause issues with PCBGROUPS/RSS until the IP defragment path grows some
code to re-calculate the RSS hash.

Handle nested exceptions in bhyve.

A nested exception condition arises when a second exception is triggered while

being delivered through the IDT. If an exception is triggered while handling
the VM-exit it will be treated like a nested exception.
