b300c1d8f9 The pseudocode in the synopsis didn't come close to actually
compiling, since <stdio.h> correctly doesn't declare off_t although
the pseudo-prototypes for the new fseeko() and ftello() functions
use it.  Handle this like the corresponding problem for va_list
versus the vprintf() family.

Fixed some English errors.

07799a2af1 Backed out most of rev.1.4. I didn't submit it; I only submitted a
request for it something like it.  It was poorly worded and too
far from both POSIX wording and normal (mal)practice by referring to
sysconf(_SC_NGROUPS_MAX) instead of {NGROUPS_MAX} or NGROUPS.  POSIX.1
uses curly braces to mark up "symbolic constants or limits [that may
be] defined in certain headers".  Since we don't document this markup,
don't use it.  Just use NGROUPS_MAX.

abd022381d Changed the type of quotactl()'s 4th arg from char *' to void *'
so that non-sloppy applications can call it without using disgusting
casts to avoid warnings.  The 4th arg is sort of varargs -- it must
sometimes represent a filename, sometimes a struct pointer, and is
sometimes unused.  The arg type is still caddr_t in the kernel.

2907af2a96 Mostly remove the VM_STACK OPTION.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.

As the author says:

|I ran into a problem pulling out the VM_STACK option.  I was aware of this
|when I first did the work, but then forgot about it.  The VM_STACK stuff
|has some code changes in the i386 branch.  There need to be corresponding
|changes in the alpha branch before it can come out completely.

what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in.  This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches.  The vm_map_entry will then always have one
|extra element (avail_ssize).  It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c.  This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch.  I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

2e4513990b Ignore the fs_spec entry for "/" in /etc/fstab if the device which
is actually mounted on "/" can be determined using statfs() and is
in /dev.  This fixes fsck operating on the wrong device when the
fs_spec entry is only an alias.  The aliased case became more
dangerous when the ROOTSLICE_HUNT hack was committed in mount(8).
ROOTSLICE_HUNT may be unnecessary now.

86854f0360 A feeble attempt at kld compatability. The mount_* programs assume that
they cannot mount a filesystem that they cannot see in getvfsbyname().
Part 1 of this is a hack, make vfsisloadable() always return true - the
ultimate decider of whether it's loadable or not is kldload() or mount().
Part 2 of this is to have vfsload() call kldload(2) and return success if
it works.  This means that we will use a viable kld module in preference
to an LKM!
Ultimately, the thing to do is remove the hacks to do a vfsload in all the
mount_* commands and let the kernel do it by itself in mount(2).

Bruce Evans
0890dc6f44 vfork -> fork. The child calls execl() which calls malloc(), so
vfork() can't be used.  We could use alloca() in execl() so that
it can be called between vfork() and execve(), but a "portable"
popen() shouldn't depend on this.  Calling execle() instead of
execl() should be fairly safe, since execle() is supposed to be
callable from signal handlers and signal handlers can't call
malloc().  However, execle() is broken.

d988805a1f Back out part of previous commit (even though it's technically correct).
Our spinlock implementation allows a particular thread to obtain a lock
multiple times, but release the lock with a single unlock call.  Since
we're detecting recursion, we know the lock is already owned by the
current thread in a previous call and must not be released in the
current call.  This is really far too dependent on this particular
spinlock implementation, so I've added commented out calls to
THREAD_UNLOCK in the appropriate places.  We can activate this code when
spinlock is taught to count each lock operation.

94ad719cf4 Add reallocf to the library. This function is simliar to realloc, but
when it returns NULL to indicate failure, it will also free the memory
that was passed to it, if that was non-null.

This does not change the semantics of realloc.

A second commit will be done to commit the conversion of those places in
the code that can safely use this to avoid memory leaks when confronted
with low memory situations.

1ce4aec2b4 Change the sanity test here. It's not correct to assume that the record
size we receive here should fit into the receive buffer. Unfortunately,
there's no 100% foolproof way to distinguish a ridiculously large record
size that a client actually meant to send us from a ridiculously large
record size that was sent as a spoof attempt.

The one value that we can positively identify as bogus is zero. A
zero-sized record makes absolutely no sense, and sending an endless
supply of zeroes will cause the server to loop forever trying to
fill its receive buffer.

Note that the changes made to readtcp() make it okay to revert this
sanity test since the deadlock case where a client can keep the server
occupied forever in the readtcp() select() loop can't happen anymore.
This solution is not ideal, but is relatively easy to implement. The
ideal solution would be to re-arrange the way dispatching is handled
so that the select() loop in readtcp() can be eliminated, but this is
difficult to implement. I do plan to implement the complete solution
eventually but in the meantime I don't want to leave the RPC library
totally vulnerable.

That you very much Sun, may I have another.

a6e95b4420 Improve DoS avoidance in RPC stream oriented transports. The TCP transport
uses readtcp() to gather data from the network; readtcp() uses select(),
with a timeout of 35 seconds. The problem with this is that if you
connect to a TCP server, send two bytes of data, then just pause, the
server will remain blocked in readtcp() for up to 35 seconds, which is
sort of a long time. If you keep doing this every 35 seconds, you can
keep the server occupied indefinitely.

To fix this, I modified readtcp() (and its cousin, readunix() in svc_unix.c)
to monitor all service transport handles instead of just the current socket.
This allows the server to keep handling new connections that arrive while
readtcp() is running. This prevents one client from potentially monopolizing
a server.

Also, while I was here, I fixed a bug in the timeout calculations. Someone
attempted to adjust the timeout so that if select() returned EINTR and the
loop was restarted, the timeout would be reduced so that rather than waiting
for another 35 seconds, you could never wait for more than 35 seconds total.
Unfortunately, the calculation was wrong, and the timeout could expire much
sooner than 35 seconds.

a9352e90f0 Patch RPC library to avoid possible denial of service attacks as described
recently in BUGTRAQ. The set_input_fragment() routine in the XDR record
marking code blindly trusts that the first two bytes it sees will in fact
be an actual record header and that the specified size will be sane. In
fact, if you just telnet to a listening port of an RPC service and send a
few carriage returns, set_input_fragment() will obtain a ridiculously large
record size and sit there for a long time trying to read from the network.

A sanity test is required: if the record size is larger than the receive
buffer, punt.

think it is appropriate to change 'long' to 'int'. I don't see why the
code couldn't be fixed so that using natural long variables does the
right thing. It's spaggetti code so it'll take some effort. Obviously
NetBSD thought so too because they change 'long' to 'int32_t' etc
and left it at that. As a temporary measure FreeBSD/Alpha can use the
NetBSD code and put this on the list of things to fix.

file works with libpthread, but when built into libc_r which has a non-weak

links the wrong symbol. The linker behaviour is a byproduct of what
the program calls from object to object so it is like winning a lottery
if the program actually works. The odds are quite good - 95:1, I think.
We need a sure thing, though, so weak symbols can't be used instead
of renaming things.

abd529ceba Yikes, this is the worst of the lot. Bruce suggested doing this (!).
Include the architecture specific sys makefile like previously, but
what this contains differs. It defines MDASM which list architecture
specific asm code that *replaces* syscalls of the same name defined
in MIASM (which gets defined by the syscall.mk or netbsd_syscall.mk
dependent of NETBSD_SYSCALLS being defined). If a syscall has a
C source implementation or something funny done to it, or just doesn't
need default asm source generated for it, then it is listed in NOASM.

syscall.mk is generated by makesyscalls.sh with other syscall files.
netbsd_syscall.mk is a hand-generated equivalent. So if a new syscall
is added and no other makefiles are edited, it will automatically have
the default asm source generated for it (whether you want it or not).

Anything listed in MDASM gets added to SRCS and gets built. For
each syscall name in MIASM, if it doesn't exist in MDASM or NOASM,
it gets added to the ASM or ASMR lists to have code generated for it.
If the syscall name was listed in HIDDEN_SYSCALLS (intended for use
by libc_r, not libc which has it defined, but empty), then the name
is added to the ASMR list and gets renamed before being built;
otherwise it is added to the ASM list and gets built with the same
name.

I wonder if this is too complicated. But it works on both i386 and alpha.

8258119519 Function to return a pointer to the non-threaded errno. This is declared
with a weak symbol so that it won't be linked when linking against
libc_r or libpthread.

98617a2c12 Define empty variables in case no names are added to them. This avoids
substitution errors for variables that don't exist.

If a machine architecture dependent makefile exists, include it
to discover if libc or libc_r is being built with NetBSD syscalls
instead of FreeBSD ones.

Put a NO_QUAD thingy around the quad makefile so that 64-bit
architectures can ignore that sh*t.

In the test for MDSRCS being empty, add all MISRCS to SRCS, rather
than just ignoring them.
