1f4b63f824 Add various utrace's for use with ktrace to the ELF runtime linker. To
activate the traces, set the LD_UTRACE (or LD_32_UTRACE) environment
variable.  This also includes code in kdump(8) to parse the traces.

5fd885b07b Fix the buggy rev. 1.117. dagmembers are only initialized for dlopen'ed
dso that are actually loading. If dso a.so depends on b.so, then dlsym
with handle from dlopen("b.so") will fail unconditionally.

Correct implementation shall use the Obj_Entry.needed list to walk
dependencies DAG.

d0cb0064fe When looking up the symbol by dlsym, look it not only in the object

Also, const-ify the read-only parameter objlist of symlook_list.

e8ea7f0260 1. Attempt to take one bullet out of the foot-shooting gun by silently
ignoring errors when sourcing rc.conf* files. The most common error
occurs when users put a command of some sort into those files.
(ifconfig is a popular choice)

2. Make the file rotation logic simpler by starting one down from
the "top" of the list, rather than at the top.

3. Try to make file rotation more secure by calling unlink(1) on all
new file names before rotating an old file to the new name, rather than
merely calling 'rm -f' on any files that exceed the number of files
to save.

we included the length of the path in the returned size but not the length

attempting to allocate a structure to hold the search path information
would allocate too small of a buffer and rtld would overrun the buffer

0fcbbd7bea When PAM support was added to rexecd in revision 1.29 (just prior to
5.0-RELEASE), a visually elusive bug was introduced.  A comparison
operator was changed to assignment.  As a result, rexecd behaved
always as if the `-i' option had been specified.  It would allow root
logins.  This commit corrects the situation in the obvious way.

A separate bug was introduced at the same time.  The PAM library
functions are called between the invocation of getpwnam(3) and the use
of the returned static object.  Since many PAM library functions
result in additional getpwnam(3) calls, the contents of the returned
static object could be changed from under rexecd.  With this commit,
getpwnam_r(3) is used instead.

Other PAM-using applications should be reviewed for similar errors in
getpw* usage.

Security:	rexecd's documented default policy of disallowing root
		logins was not enforced.

4cd51076c5 Improve handling SIGURG and OOB commands on the control channel.
The major change is to process STAT sent as an OOB command w/o
breaking the current data transfer.  As a side effect, this gives
better error checking in the code performing data transfers.

A lesser, but in no way cosmetic, change is using the flag `recvurg'
in the only signal-safe way that has been blessed by SUSv3.  The
other flag, `transflag,' becomes private to the SIGURG machinery,
serves debugging purposes only, and may be dropped in the future.

The `byte_count' global variable is now accounting bytes actually
transferred over the network.  This can give status messages looking
strange, like "X of Y bytes transferred," where X > Y, but that has
more sense than trying to compensate for combinations of data formats
on the server and client when transferring ASCII type data.  BTW,
getting the size of a file in advance is unreliable for a number of
reasons in the first place.  See question 18.8 of the Infrequently
Asked Questions in comp.lang.c for details.

 _target_ (and the target is /usr/libexec/ld-elf.so.1) doesn't have

7bc7e0c85e 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.

d05bb9a2a6 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.

c707fea10b 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.

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".

 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

4afa371832 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.

e25d3184d0 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.

table is used implicitly, but newer versions of binutils don't initialize

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.

7194d335cf 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.

6cfbc84115 Let tilde expansion be done even if a file/directory doesn't exist yet.
This makes such natural commands as "MKD ~user/newdir" or "STOR ~/newfile"
do what they are supposed to instead of failing miserably with the
"File not found" error.

This involves a bit of code reorganization.  Namely, the code doing
glob(3) expansion has been separated to a function; a new function
has been introduced to do tilde expansion; the latter function is
invoked on a pathname before the former one.  Thus behaviour mimicing
that of the Bourne shell has been achieved.

ce9287fc02 Give the code around chroot(2)/chdir(2) a major overhaul by
separating its part around chroot(2) from that around initial
chdir(2).  This makes the below changes really easy.

Move seteuid(to user's uid) to before calling chdir(2).  There are
two goals to achieve by that.  First, NFS mounted home directories
with restrictive permissions become accessible (local superuser
can't access them if not mapped to uid 0 on the remote side
explicitly.)  Second, all the permissions to the home directory
pathname components become effective; previously a user could be
carried to any local directory despite its permissions since the
chdir(2) was done with euid 0.  This reduces possible impact from
FTP server misconfiguration, e.g., assigning a wrong home directory
to a user.

Implement the "/./" feature.  Now a guest or user subject to chrooting
may have "/./" in his login directory, which separates his chroot
directory from his home directory inside the chrooted environment.
This works for ftpchroot(5) as well.

fa7dd9c5bc Change the way ELF coredumps are handled. Instead of unconditionally
skipping read-only pages, which can result in valuable non-text-related
data not getting dumped, the ELF loader and the dynamic loader now mark
read-only text pages NOCORE and the coredump code only checks (primarily) for
complete inaccessibility of the page or NOCORE being set.

Certain applications which map large amounts of read-only data will
produce much larger cores.  A new sysctl has been added,
debug.elf_legacy_coredump, which will revert to the old behavior.

This commit represents collaborative work by all parties involved.
The PR contains a program demonstrating the problem.

it necessary to actually reserve the space for the BOR (Bind On
Reference) entries as pointed to by the DTE. As a result, relocatable
data in the PLT was overwritten, causing some unexpected control flow
with annoyingly predictable outcome: coredump.
To reproduce:
	% echo 'int main() { return 0; }' > foo.c
	% cc -o foo foo.c -lxpg4

o Ignore REST marker on APPE.  No RFC specifies this case,

o By default, deny upload resumes and appends by anonymous users.
  Previously these commands were translated to STOU silently,

e6f0183bff Remove the nanosleep calls from the spin loops in the locking code.
They provided little benefit (if any) and they caused some problems
in OpenOffice, at least in post-KSE -current and perhaps in other
environments too.  The nanosleep calls prevented the profiling timer
from advancing during the spinloops, thereby preventing the thread
scheduler from ever pre-empting the spinning thread.  Alexander
Kabaev diagnosed this problem, Martin Blapp helped with testing,
and Matt Dillon provided some helpful suggestions.

This is a short-term fix for a larger problem.  The use of spinlocking
isn't guaranteed to work in all cases.  For example, if the spinning
thread has higher priority than all other threads, it may never be
pre-empted, and the thread holding the lock may never progress far
enough to release the lock.  On the other hand, spinlocking is the
only locking that can work with an arbitrary unknown threads package.

I have some ideas for a much better fix in the longer term.  It
would eliminate all locking inside the dynamic linker by making it
safe for symbol lookups and lazy binding to proceed in parallel
with a call to dlopen or dlclose.  This means that the only mutual
exclusion needed would be to prevent multiple simultaneous calls
to dlopen and/or dlclose.  That mutual exclusion could be put into
the native pthreads library.  Applications using foreign threads
packages would have to make their own arrangements to ensure that
they did not have multiple threads in dlopen and/or dlclose -- a
reasonable requirement in my opinion.

origin on the request.  We use this to implement rudimentary visibility
control on our user information.

Make sure that the child process's standard error goes through the same
NVT-ASCII filter as is applied to the standard output.

Don't attempt to call logerr() from the child since stdio is not safe in
a vforked process.  Just write a message to fd 2 instead.  (Ideally, the
parent would open two pipes, and siphon off our stderr to some place less
public, but I have not attempted to do so in this implementation.)

b603db3019 In tracking down an installation seg fault with then openoffice port
Martin Blapp determined that the elf dynamic loader was at fault.  In
particular, the loader uses alloca() to allocate a symbol cache on the
stack.  Normally this would work just fine, but if the loader is called
from a threaded program and the object being loaded is fairly large the
alloca() can blow away the thread stack and effect other nearby thread
stacks as well.  My testing showed that the symbol cache can be as large
as 250KBytes during the openoffice port build and install sequence.  Martin
was able to work around the problem by disabling the symbol cache
(cache = NULL;).  However, this solution is not adequate for commit because
it can cause an enormous cpu burden for applications which do a lot of
dynamic loading (e.g. like konqueror).

The solution is to use anonymous mmap() to temporarily allocate space to
hold the symbol cache.  In testing I found that replacing the alloca()
with mmap() has no observable degredation in performance.

It should be noted that this bug does not necessarily cause an immediate
crash but can instead result in long term corruption and instability in
applications that load modules from threads.  The bug is almost certainly
responsible for some of the instabilities found in konqueror, for example,
and possibly netscape too.

859be0911a Add an IPv6 support.
I dunno if there is an IPv6 supported rexec client.  So, it was
tested that this change doesn't break an IPv4.

ff93f08c06 Better handle the case with a network that drops packets by retrying
with a back off.  This was discovered when Luigi sent me code to
handle this for Etherboot.  The Etherboot patch worked okay but
FreeBSD's tftpd had trouble handling it and would fail to transfer
the file since it would abort on send and not retry.

968253905e Fix a relocation bug in the ia64 ld.so. Weak function pointers in shared
objects were not being correctly set to zero.  Instead, the function
descriptor pointer was set to the load address of the .so object.  This
caused gcc generated binaries to segfault on exit when crtbegin.asm's
_fini code tested the __cxa_finalize() function pointer for zero.

This is a bit of a hack because of a problem nearby workaround for
find_symdef and its quirks (failures) for local symbols.  This still
needs to be fixed.

79723020c0 o MAXPATHLEN is the correct constant to use for path names, it includes
the NULL.
o use snprintf in preference to unchecked strcat in a couple of places that
  likely can't overflow.  Makes it easier to grep for strcpy :-)

7d0babda6d Teach REST how to restart a file transfer after 2^31 bytes: now yylex()
returns off_t in yylval.u.o. REST is the only user of yylval.u.o at the
moment.

NB: seems lukemftpd has the same bug.

6a0f754781 CPP v3.1 has different rules for processing #lines directives. This
sometimes causes fewer directories to be searched for includes.  Thus
we have to be more explicit in our search list.

it was inelegant and neglected to check the return value from malloc(3).
