Hans de Goede [Tue, 15 Aug 2006 10:09:27 +0000 (12:09 +0200)]
[PATCH] PATCH: 1 line 2.6.18 bugfix: modpost-64bit-fix.patch

There is a small but annoying bug in scripts/mod/file2alias.c which causes
it to generate invalid aliases for input devices on 64 bit archs. This causes
joydev.ko to not be automaticly loaded when inserting a joystick, resulting in
a non working joystick (for the average user).

In scripts/mod/file2alias.c is the following code for generating the input
aliases:
static void do_input(char *alias,
                     kernel_ulong_t *arr, unsigned int min, unsigned int max)
{
        unsigned int i;

        for (i = min; i < max; i++)
                if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG)))
                        sprintf(alias + strlen(alias), "%X,*", i);
}

On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*"
for the second etc.

However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20
+ first entry (hex) ! to the list of hex codes, which is 32 more then the first
entry, thus is because the bit test above wraps at 32 bits instead of 64.

scripts/mod/file2alias.c, line 379 reads:
                if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG)))
That should be:
                if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG)))

Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a
64 bit long, and when that int gets shifted >= 32 times, appearantly the number
by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits
too low.

The patch below makes the nescesarry 1 char change :)

18 years ago[PATCH] futex_handle_fault always fails
john stultz [Mon, 14 Aug 2006 06:24:24 +0000 (23:24 -0700)]
[PATCH] futex_handle_fault always fails

We found this issue last week w/ the -RT kernel, but it seems the same
issue is in mainline as well.

Basically it is possible for futex_unlock_pi to return without actually
freeing the lock.  This is due to buggy logic in the use of
futex_handle_fault() and its attempt argument in a failure case.

Looking at futex.c the logic is as follows:

1) In futex_unlock_pi() we start w/ ret=0 and we go down to the first
   futex_atomic_cmpxchg_inatomic(), where we find uval==-EFAULT.  We then
   jump to the pi_faulted label.

2) From pi_faulted: We increment attempt, unlock the sem and hit the
   retry label.

3) From the retry label, with ret still zero, we again hit EFAULT on the
   first futex_atomic_cmpxchg_inatomic(), and again goto the pi_faulted
   label.

4) Again from pi_faulted: we increment attempt and enter the
   conditional, where we call futex_handle_fault.

5) futex_handle_fault fails, and we goto the out_unlock_release_sem
   label.

6) From out_unlock_release_sem we return, and since ret is still zero,
   we return without error, while never actually unlocking the lock.

Issue #1: at the first futex_atomic_cmpxchg_inatomic() we should probably
be setting ret=-EFAULT before jumping to pi_faulted: However in our case
this doesn't really affect anything, as the glibc we're using ignores the
error value from futex_unlock_pi().

Issue #2: Look at futex_handle_fault(), its first conditional will return
-EFAULT if attempt is >= 2.  However, from the "if(attempt++)
futex_handle_fault(attempt)" logic above, we'll *never* call
futex_handle_fault when attempt is less then two.  So we never get a chance
to even try to fault the page in.

The following patch addresses these two issues by 1) Always setting ret to
-EFAULT if futex_handle_fault fails, and 2) Removing the = in
futex_handle_fault's (attempt >= 2) check.

I'm really not sure this is the right fix, but wanted to bring it up so
folks knew the issue is alive and well in the current -git tree.  From
looking at the git logs the logic was first introduced (then later copied
to other places) in the following commit almost a year ago:

[INET]: Use pskb_trim_unique when trimming paged unique skbs

(since the packet hasn't been given to anything else in the system).

This broke because skb_trim no longer allows paged packets to be

[NETFILTER]: ulog: fix panic on SMP kernels

Fix kernel panic on various SMP machines. The culprit is a null
ub->skb in ulog_send(). If ulog_timer() has already been scheduled on
one CPU and is spinning on the lock, and ipt_ulog_packet() flushes the
queue on another CPU by calling ulog_send() right before it exits,
there will be no skbuff when ulog_timer() acquires the lock and calls
ulog_send(). Cancelling the timer in ulog_send() doesn't help because
it has already been scheduled and is running on the first CPU.

Similar problem exists in ebt_ulog.c and nfnetlink_log.c.

[IPSEC]: Validate properly in xfrm_dst_check()

If dst->obsolete is -1, this is a signal from the
bundle creator that we want the XFRM dst and the
dsts that it references to be validated on every
use.

I misunderstood this intention when I changed
xfrm_dst_check() to always return NULL.

Now, when we purge a dst entry, by running dst_free()
on it.  This will set the dst->obsolete to a positive
integer, and we want to return NULL in that case so
that the socket does a relookup for the route.

Thus, if dst->obsolete<0, let stale_bundle() validate
the state, else always return NULL.

In general, we need to do things more intelligently
here because we flush too much state during rule
changes.  Herbert Xu has some ideas wherein the key
manager gives us some help in this area.  We can also

Found during OpenVZ internal testing.

At first we thought that it is OpenVZ specific as we
added dst_run_gc(0) call in dst_dev_event(),
but as Alexey pointed to me it is possible to trigger
this condition in mainstream kernel.

F.e. timer has fired on CPU2, but the handler was preeempted
by an irq before dst_lock is tried.
Meanwhile, someone on CPU1 adds an entry to gc list and
starts the timer.
If CPU2 was preempted long enough, this timer can expire
simultaneously with resuming timer handler on CPU1, arriving
exactly to the situation described.

Michael Chan [Tue, 8 Aug 2006 04:46:02 +0000 (21:46 -0700)]
[TG3]: Fix tx race condition

Fix a subtle race condition between tg3_start_xmit() and tg3_tx()
discovered by Herbert Xu <herbert@gondor.apana.org.au>:

CPU0 CPU1
tg3_start_xmit()
if (tx_ring_full) {
tx_lock
tg3_tx()
if (!netif_queue_stopped)
netif_stop_queue()
if (!tx_ring_full)
update_tx_ring
netif_wake_queue()
tx_unlock
}

Even though tx_ring is updated before the if statement in tg3_tx() in
program order, it can be re-ordered by the CPU as shown above.  This
scenario can cause the tx queue to be stopped forever if tg3_tx() has
just freed up the entire tx_ring.  The possibility of this happening
should be very rare though.

The following changes are made:

1. Add memory barrier to fix the above race condition.

2. Eliminate the private tx_lock altogether and rely solely on
netif_tx_lock.  This eliminates one spinlock in tg3_start_xmit()
when the ring is full.

3. Because of 2, use netif_tx_lock in tg3_tx() before calling
netif_wake_queue().

4. Change TX_BUFFS_AVAIL to an inline function with a memory barrier.
Herbert and David suggested using the memory barrier instead of
volatile.

5. Check for the full wake queue condition before getting
netif_tx_lock in tg3_tx().  This reduces the number of unnecessary
spinlocks when the tx ring is full in a steady-state condition.

6. Update version to 3.65.

During OpenVZ stress testing we found that UDP traffic with random src

It was found that for 4GB i686 system (having 1048576 total pages and

bytes) => ip_rt_max_size = 4194304 entries, i.e.  max rt size is
4194304 * 256b = 1Gb of RAM > normal_zone
