d786b94f15 Change `(foo *)0'' to `NULL'' where it's possible
(and it appears possible throughout ftpd(8) source.)

It is not a mere issue of style: Null pointers in C
seem to have been mistaken one way or another quite often.

9fb1cda8d0 Open a socket for a data transfer in active mode using euid
of the current user, not root.  This will allow neat things
like matching anonymous FTP data traffic with a single ipfw(8)
rule:
	ipfw add ... tcp from any to any uid ftp

Note that the control connection socket still belongs to the
user ftpd(8) was started from, usually root.

86ff38aa6a o Reduce path names in RRQ and WRQ packets by:
Reducing "/+./" strings to "/"
    Reducing "/[^/]+/../" to "/"

o Don't send an OACK when the result of the [RW]RQ is an error.

These changes allow tftpd to interact with pxelinux.bin from the syslinux
package.

Whilst the path reducing code doesn't properly handle situations where the
path component before the "/../" is a symlink to (say) ".", I would suggest
that it does the right thing in terms of the clients perception of what
their path string actually represents.  This seems better than using
realpath() and breaking environments where symlinks point outside of the
directory hierarchy that tftpd is configured to allow.

1dc333167a Fix the problem that surfaced with the new binutils import on sparc64
(and that is for now being worked around by a binutils patch).

The rtld code tested &_DYNAMIC against 0 to see whether rtld itself
was built as PIC or not. While the sparc64 MD code did not rely
on the preset value of the GOT slot for _DYNAMIC any more due
to previous binutils changes, it still used to not be 0, so
that this check did work. The new binutils do however initialize
this slot with 0. As a consequence, rtld would not properly initialize
itself and crash.
Fix that by introducing a new macro, RTLD_IS_DYNAMIC, to take the role
of this test. For sparc64, it is implemented using the rtld_dynamic()
code that was already there. If an architecture does not provide its
own implementation, we default to the old check.

While being there, mark _DYNAMIC as a weak symbol in the sparc64
rtld_start.S. This is needed in the LDSCRIPT case, which is however
not currently supported for want of an actual ldscript.

Sanity checked with md5 on alpha, amd64, i386 and ia64.

88a11443a2 More stack alignment fixes. Arrange so we call _rtld() in ld-elf.so.1
with the correct alignment.  This is important because this calls to
library static constructors are made from here.  The bug in the old crt*.s
files hid this because in this case, two wrongs do indeed make a right.
Also, call _rtld_bind() with the correct alignment, because it calls back
into the pthread library locking functions.  If things happen just
the wrong way, we get a SIG10 due to the broken stack alignment.

This adds the former ports registered groups: proxy and authpf as well as

installworld without errors.

This also provides the passive OS fingerprints from OpenBSD (pf.os) and an
example pf.conf.

For those who want to go without pf; it provides a NO_PF knob to make.conf.

__FreeBSD_version will be bumped soon to reflect this and to be able to

0b0ae8e16e Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

54bb06645b Add skeleton build dirs for pf userland:
libexec/ftp-proxy	- ftp proxy for pf
 sbin/pfctl		- equivalent to sbin/ipf
 sbin/pflogd		- deamon logging packets via if_pflog in pcap format
 usr.sbin/authpf	- authentification shell to modify pf rulesets

Bring along some altq headers used to satisfy pfctl/authpf compile. This
helps to keep the diff down and will make it easy to have a altq-patchset
use the full powers of pf.

Also make sure that the pf headers are installed.

This does not link anything to the build. There will be a NO_PF switch for
make.conf once pf userland is linked.

d6aec2b6d6 Very big makeover in the way telnet, telnetd and libtelnet are built.
Previously, there were two copies of telnet; a non-crypto version
that lived in the usual places, and a crypto version that lived in
crypto/telnet/. The latter was built in a broken manner somewhat akin
to other "contribified" sources. This meant that there were 4 telnets
competing with each other at build time - KerberosIV, Kerberos5,
plain-old-secure and base. KerberosIV is no longer in the running, but
the other three took it in turns to jump all over each other during a
"make buildworld".

As the crypto issue has been clarified, and crypto _calls_ are not
a problem, crypto/telnet has been repo-copied to contrib/telnet,
and with this commit, all telnets are now "contribified". The contrib
path was chosen to not destroy history in the repository, and differs
from other contrib/ entries in that it may be worked on as "normal"
BSD code. There is no dangerous crypto in these sources, only a
very weak system less strong than enigma(1).

Kerberos5 telnet and Secure telnet are now selected by using the usual
macros in /etc/make.conf, and the build process is unsurprising and
less treacherous.

beedaf29a1 Block SIGURG while reading from the control channel.
Rationale:

SIGURG is configured by ftpd to interrupt system calls, which is useful
during data transfers.  However, SIGURG could interrupt I/O on the
control channel as well, which was mistaken for the end of the session.

A practical example could be aborting the download of a tiny file,
when the abort sequence reached ftpd after ftpd had passed the file
data to the system and returned to its command loop.

151e14e2da Avoid using the global offset table to get the address of _DYNAMIC in
rtld.  When _DYNAMIC is referenced normally from C the global offset
table is used implicitly, but newer versions of binutils don't initialize
it statically in the binary, so this doesn't work until rtld is relocated,
which _DYNAMIC is needed for...  So, as on other systems with the same
problem, we disassemble a call instruction to _DYNAMIC in order to get
its address.

f432014308 Run a revision of the devstat interface:
Kernel:

Change statistics to use the *uptime() timescale (ie: relative to
boottime) rather than the UTC aligned timescale.  This makes the
device statistics code oblivious to clock steps.

Change timestamps to bintime format, they are cheaper.

Remove the "busy_count", and replace it with two counter fields:
"start_count" and "end_count", which are updated in the down and
up paths respectively.  This removes the locking constraint on
devstat.

Add a timestamp argument to devstat_start_transaction(), this will
normally be a timestamp set by the *_bio() function in bp->bio_t0.
Use this field to calculate duration of I/O operations.

Add two timestamp arguments to devstat_end_transaction(), one is
the current time, a NULL pointer means "take timestamp yourself",
the other is the timestamp of when this transaction started (see
above).

Change calculation of busy_time to operate on "the salami principle":
Only when we are idle, which we can determine by the start+end
counts being identical, do we update the "busy_from" field in the
down path.  In the up path we accumulate the timeslice in busy_time
and update busy_from.

Change the byte_* and num_* fields into two arrays: bytes[] and
operations[].

Userland:

Change the misleading "busy_time" name to be called "snap_time" and
make the time long double since that is what most users need anyway,
fill it using clock_gettime(CLOCK_MONOTONIC) to put it on the same
timescale as the kernel fields.

Change devstat_compute_etime() to operate on struct bintime.

Remove the version 2 legacy interface: the change to bintime makes
compatibility far too expensive.

Fix a bug in systat's "vm" page where boot relative busy times would
be bogus.

80e27851f2 Do not remove object from the lists at the unref_dag() stage.
Introduce a new unlink_object() function and call it in
unload_object() instead. Removing the object in unref_dag() is
too early, rtld calls _fini() function after that and shared
objects might fail resolve their own symbols.

76b4e9c51c When unloading dependencies make sure they are removed from all the
associated lists:
   remove RTLD_GLOBAL objects from global objects list;
   remove the parent object from dldags list of its children.

Previosly we were doing that only to the top-level object OF the DAG
being unloaded and all its dependencies were ignored, leading to
mysterious crashes later.
