[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.

[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:

If dst->obsolete is -1, this is a signal from the

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

[XFS] Fix xfs_free_extent related NULL pointer dereference.
We recently fixed an out-of-space deadlock in XFS, and part of that fix
involved the addition of the XFS_ALLOC_FLAG_FREEING flag to some of the
space allocator calls to indicate they're freeing space, not allocating
it. There was a missed xfs_alloc_fix_freelist condition test that did not
correctly test "flags". The same test would also test an uninitialised
structure field (args->userdata) and depending on its value either would
or would not return early with a critical buffer pointer set to NULL.
This fixes that up, adds asserts to several places to catch future botches
of this nature, and skips sections of xfs_alloc_fix_freelist that are
irrelevent for the space-freeing case.

Patch from Dmitry Mishin <dim@openvz.org>:
Replace add_timer() by mod_timer() in dst_run_gc

CPU1 CPU2
dst_run_gc() entered dst_run_gc() entered
spin_lock(&dst_lock) .....
del_timer(&dst_gc_timer) fail to get lock
.... mod_timer() <--- puts

to the list
add_timer(&dst_gc_timer) <--- BUG because timer is in list already.
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.

[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.

If a process requests a lock cancel but the lock has been remotely granted
already then there is no need to send the cancel message.

ocfs2: do not modify lksb->status in the unlock ast
This can race with other ast notification, which can cause bad status values
to propagate into the unlock ast.

[S390] xpram system device class.
Remove system device class for xpram. It creates the directory hierarchy
under /sys/devices/system/xpram/xpram0. The xpram0 directory is empty and
it is always created while xpram1 and following devices are always missing,
independent if the devices exist or not. Since the xpram devices are
listed in /proc/partitions and /sys/block/ as slram<x> the system device
class for xpram is meaningless.

[S390] lost interrupt after chpid vary off/on cycle.
I/O on a CCW device may stall if a channel path to that device is
logicaly varied off/on. A user I/O interrupt can get misinterpreted
as interrupt for an internal path verification operation due to a
missing check and is therefore never reported to the device driver.
Correct check for pending interruptions before starting path
verification.
