[NET] random : secure_tcp_sequence_number should not assume CONFIG_KTIME_SCALAR
[ Upstream commit: 6dd10a62353a50b30b30e0c18653650975b29c71 ]
All 32 bits machines but i386 dont have CONFIG_KTIME_SCALAR. On these
machines, ktime.tv64 is more than 4 times the (correct) result given
by ktime_to_ns()
Again on these machines, using ktime_get_real().tv64 >> 6 give a
32bits rollover every 64 seconds, which is not wanted (less than the
120 s MSL)
Using ktime_to_ns() is the portable way to get nsecs from a ktime, and
have correct code.

[NETFILTER]: Fix NULL pointer dereference in nf_nat_move_storage()
[ Upstream commit: 7799652557d966e49512479f4d3b9079bbc01fff ]
Reported by Chuck Ebbert as:
https://bugzilla.redhat.com/show_bug.cgi?id=259501#c14
This routine is called each time hash should be replaced, nf_conn has
extension list which contains pointers to connection tracking users
(like nat, which is right now the only such user), so when replace takes
place it should copy own extensions. Loop above checks for own
extension, but tries to move higer-layer one, which can lead to above
oops.

------------------
From: Christian Borntraeger <[email protected]>
commit 5d0360ee96a5ef953dbea45873c2a8c87e77d59b upstream.
We have seen ramdisk based install systems, where some pages of mapped
libraries and programs were suddendly zeroed under memory pressure. This
should not happen, as the ramdisk avoids freeing its pages by keeping
them dirty all the time.
It turns out that there is a case, where the VM makes a ramdisk page
clean, without telling the ramdisk driver. On memory pressure
shrink_zone runs and it starts to run shrink_active_list. There is a
check for buffer_heads_over_limit, and if true, pagevec_strip is called.
pagevec_strip calls try_to_release_page. If the mapping has no
releasepage callback, try_to_free_buffers is called. try_to_free_buffers
has now a special logic for some file systems to make a dirty page
clean, if all buffers are clean. Thats what happened in our test case.
The simplest solution is to provide a noop-releasepage callback for the
ramdisk driver. This avoids try_to_free_buffers for ramdisk pages.

[PKT_SCHED]: Check subqueue status before calling hard_start_xmit
[ Upstream commit: 5f1a485d5905aa641f33009019b3699076666a4c ]
The only qdiscs that check subqueue state before dequeue'ing are PRIO
and RR. The other qdiscs, including the default pfifo_fast qdisc,
will allow traffic bound for subqueue 0 through to hard_start_xmit.
The check for netif_queue_stopped() is done above in pkt_sched.h, so
it is unnecessary for qdisc_restart(). However, if the underlying
driver is multiqueue capable, and only sets queue states on subqueues,
this will allow packets to enter the driver when it's currently unable
to process packets, resulting in expensive requeues and driver
entries. This patch re-adds the check for the subqueue status before
calling hard_start_xmit, so we can try and avoid the driver entry when
the queues are stopped.

patch a98ce5c6feead6bfedefabd46cb3d7f5be148d9a in mainline.
Fix synchronize_irq races with IRQ handler
As it is some callers of synchronize_irq rely on memory barriers
to provide synchronisation against the IRQ handlers. For example,
the tg3 driver does
tp->irq_sync = 1;
smp_mb();
synchronize_irq();
and then in the IRQ handler:
if (!tp->irq_sync)
netif_rx_schedule(dev, &tp->napi);
Unfortunately memory barriers only work well when they come in
pairs. Because we don't actually have memory barriers on the
IRQ path, the memory barrier before the synchronize_irq() doesn't
actually protect us.
In particular, synchronize_irq() may return followed by the
result of netif_rx_schedule being made visible.
This patch (mostly written by Linus) fixes this by using spin
locks instead of memory barries on the synchronize_irq() path.

patch 9e555930bd873d238f5f7b9d76d3bf31e6e3ce93 in mainline.
Fix a long boot delay in the forcedeth driver. During initialization, the
timeout for the handshake between mgmt unit and driver can be very long.
The patch reduces the timeout by eliminating a extra loop around the
timeout logic.

From: Thomas Gleixner <[email protected]>
patch 62f0f61e6673e67151a7c8c0f9a09c7ea43fe2b5 in mainline
Relative hrtimers with a large timeout value might end up as negative
timer values, when the current time is added in hrtimer_start().
This in turn is causing the clockevents_set_next() function to set an
huge timeout and sleep for quite a long time when we have a clock
source which is capable of long sleeps like HPET. With PIT this almost
goes unnoticed as the maximum delta is ~27ms. The non-hrt/nohz code
sorts this out in the next timer interrupt, so we never noticed that
problem which has been there since the first day of hrtimers.
This bug became more apparent in 2.6.24 which activates HPET on more
hardware.

completes we skip the emulated instruction, pointing rip somewhere completely

>From Steven Rostedt <[email protected]>
patch ce6bd420f43b28038a2c6e8fbb86ad24014727b6 in mainline.
David Holmes found a bug in the -rt tree with respect to
pthread_cond_timedwait. After trying his test program on the latest git
from mainline, I found the bug was there too. The bug he was seeing
that his test program showed, was that if one were to do a "Ctrl-Z" on a
process that was in the pthread_cond_timedwait, and then did a "bg" on
that process, it would return with a "-ETIMEDOUT" but early. That is,
the timer would go off early.
Looking into this, I found the source of the problem. And it is a rather
nasty bug at that.
Here's the relevant code from kernel/futex.c: (not in order in the file)
[...]
smlinkage long sys_futex(u32 __user *uaddr, int op, u32 val,
struct timespec __user *utime, u32 __user *uaddr2,
u32 val3)
{
struct timespec ts;
ktime_t t, *tp = NULL;
u32 val2 = 0;
int cmd = op & FUTEX_CMD_MASK;
if (utime && (cmd == FUTEX_WAIT || cmd == FUTEX_LOCK_PI)) {
if (copy_from_user(&ts, utime, sizeof(ts)) != 0)
return -EFAULT;
if (!timespec_valid(&ts))
return -EINVAL;
t = timespec_to_ktime(ts);
if (cmd == FUTEX_WAIT)
t = ktime_add(ktime_get(), t);
tp = &t;
}
[...]
return do_futex(uaddr, op, val, tp, uaddr2, val2, val3);
}
[...]
long do_futex(u32 __user *uaddr, int op, u32 val, ktime_t *timeout,
u32 __user *uaddr2, u32 val2, u32 val3)
{
int ret;
int cmd = op & FUTEX_CMD_MASK;
struct rw_semaphore *fshared = NULL;
if (!(op & FUTEX_PRIVATE_FLAG))
fshared = ¤t->mm->mmap_sem;
switch (cmd) {
case FUTEX_WAIT:
ret = futex_wait(uaddr, fshared, val, timeout);
[...]
static int futex_wait(u32 __user *uaddr, struct rw_semaphore *fshared,
u32 val, ktime_t *abs_time)
{
[...]
struct restart_block *restart;
restart = ¤t_thread_info()->restart_block;
restart->fn = futex_wait_restart;
restart->arg0 = (unsigned long)uaddr;
restart->arg1 = (unsigned long)val;
restart->arg2 = (unsigned long)abs_time;
restart->arg3 = 0;
if (fshared)
restart->arg3 |= ARG3_SHARED;
return -ERESTART_RESTARTBLOCK;
[...]
static long futex_wait_restart(struct restart_block *restart)
{
u32 __user *uaddr = (u32 __user *)restart->arg0;
u32 val = (u32)restart->arg1;
ktime_t *abs_time = (ktime_t *)restart->arg2;
struct rw_semaphore *fshared = NULL;
restart->fn = do_no_restart_syscall;
if (restart->arg3 & ARG3_SHARED)
fshared = ¤t->mm->mmap_sem;
return (long)futex_wait(uaddr, fshared, val, abs_time);
}
So when the futex_wait is interrupt by a signal we break out of the
hrtimer code and set up or return from signal. This code does not return
back to userspace, so we set up a RESTARTBLOCK. The bug here is that we
save the "abs_time" which is a pointer to the stack variable "ktime_t t"
from sys_futex.
This returns and unwinds the stack before we get to call our signal. On
return from the signal we go to futex_wait_restart, where we update all
the parameters for futex_wait and call it. But here we have a problem
where abs_time is no longer valid.
I verified this with print statements, and sure enough, what abs_time
was set to ends up being garbage when we get to futex_wait_restart.
The solution I did to solve this (with input from Linus Torvalds)
was to add unions to the restart_block to allow system calls to
use the restart with specific parameters. This way the futex code now
saves the time in a 64bit value in the restart block instead of storing
it on the stack.
Note: I'm a bit nervious to add "linux/types.h" and use u32 and u64
in thread_info.h, when there's a #ifdef __KERNEL__ just below that.
Not sure what that is there for. If this turns out to be a problem, I've
tested this with using "unsigned int" for u32 and "unsigned long long" for
u64 and it worked just the same. I'm using u32 and u64 just to be
consistent with what the futex code uses.

patch cb43c54ca05c01533c45e4d3abfe8f99b7acf624 in mainline.
The APM emulation is currently broken as a result of commit
831441862956fffa17b9801db37e6ea1650b0f69
"Freezer: make kernel threads nonfreezable by default"
that removed the PF_NOFREEZE annotations from apm_ioctl() without adding
the appropriate freezer hooks. Fix it and remove the unnecessary variable flags
from apm_ioctl().
Special thanks to Franck Bui-Huu <[email protected]> for pointing out the
problem.

From: Zhao Yakui <[email protected]>
patch a7839e960675b549f06209d18283d5cee2ce9261 in mainline.
On some systems the number of resources(IO,MEM) returnedy by PNP device is
greater than the PNP constant, for example motherboard devices. It brings
that some resources can't be reserved and resource confilicts. This will
cause PCI resources are assigned wrongly in some systems, and cause hang.
This is a regression since we deleted ACPI motherboard driver and use PNP
system driver.

From: Scott James Remnant <[email protected]>
patch e6ceb32aa25fc33f21af84cc7a32fe289b3e860c in mainline.
In wait_task_stopped() exit_code already contains the right value for the
si_status member of siginfo, and this is simply set in the non WNOWAIT
case.
If you call waitid() with a stopped or traced process, you'll get the signal
in siginfo.si_status as expected -- however if you call waitid(WNOWAIT) at the
same time, you'll get the signal << 8 | 0x7f
Pass it unchanged to wait_noreap_copyout(); we would only need to shift it
and add 0x7f if we were returning it in the user status field and that
isn't used for any function that permits WNOWAIT.

------------------
From: Jean Delvare <[email protected]>
patch b64d70825abbf706bbe80be1b11b09514b71f45e in mainline.
The code in fb_ddc_read() is said to be based on the implementation of the
radeon driver:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc5891c8a3ba284f13994d7bc1f1bfa8283982de
However, comparing the old radeon driver code with the new fb_ddc code
reveals some differences. Most notably, the I2C bus lines are held at the
end of the function, while the original code was releasing them (as the
comment above correctly says.)
There are a few other differences, which appear to be responsible for read
failures on my system. While tracing low-level I2C code in i2c-algo-bit, I
noticed that the initial attempt to read the EDID always failed. It takes
one retry for the read to succeed. As we are about to remove this
automatic retry property from i2c-algo-bit, reading the EDID would really
fail.
As a summary, the I2C lines quirk which is supposedly needed to read EDID
on some older monitors is currently breaking the (first) read on all other
monitors (and might not even work with older ones - did anyone try since
October 2006?)
After applying the patch below, which makes the code in fb_ddc_read()
really similar to what the radeon driver used to have, the first EDID read
succeeds again.
On top of that, as it appears that this code has been broken for one year
now and nobody seems to have complained, I'm curious if it makes sense to
keep this quirk in place. It makes the code more complex and slower just
for the sake of monitors which I guess nobody uses anymore. Can't we just
get rid of it?

From: "Maciej W. Rozycki" <[email protected]>
patch 522939d45c293388e6a360210905f9230298df16 in mainline.
The esp_reset_cleanup() function is called with the host lock held and
invokes starget_for_each_device() which wants to take it too. Here is a
fix along the lines of shost_for_each_device()/__shost_for_each_device()
adding a __starget_for_each_device() counterpart which assumes the lock
has already been taken.
Eventually, I think the driver should get modified so that more work is
done as a softirq rather than in the interrupt context, but for now it
fixes a bug that causes the spinlock debugger to fire.
While at it, it fixes a small number of cosmetic problems with
starget_for_each_device() too.

commit 55d9fcf57ba5ec427544fca7abc335cf3da78160
Author: Matthew Wilcox <[email protected]>
Date: Mon Jul 30 15:19:18 2007 -0600
[SCSI] dpt_i2o: convert to SCSI hotplug model
- Delete refereces to HOSTS_C
- Switch to module_init/module_exit instead of detect/release
- Don't pass around the host template and rename it to adpt_template
- Switch from scsi_register/scsi_unregister to scsi_host_alloc,
scsi_add_host, scsi_scan_host and scsi_host_put.
Because it caused (for unknown reasons) Andres' all-data-reads-as-zeroes
problem, reported at

2.6.23-stable review patch. If anyone has any objections, please let us
know.
------------------
From: Li Zefan <[email protected]>
This patch fixes an incorrect memset in the NAT code, causing
misbehaviour when unloading and reloading the NAT module.
Applies to stable-2.6.22 and stable-2.6.23.
Please apply, thanks.
[NETFILTER]: nf_nat: fix memset error
Upstream commit e0bf9cf15fc30d300b7fbd821c6bc975531fab44
The size passing to memset is the size of a pointer. Fixes
misbehaviour when unloading and reloading the NAT module.

From: Evgeniy Polyakov <[email protected]>
This patch fixes a NAT regression in 2.6.23, resulting in a
crash when a connection is NATed and matches a conntrack
helper after NAT.
Please apply, thanks.
[NETFILTER]: Fix kernel panic with REDIRECT target.
Upstream commit 1f305323ff5b9ddc1a4346d36072bcdb58f3f68a
When connection tracking entry (nf_conn) is about to copy itself it can
have some of its extension users (like nat) as being already freed and
thus not required to be copied.
Actually looking at this function I suspect it was copied from
nf_nat_setup_info() and thus bug was introduced.
Report and testing from David <[email protected]>.
[ Patrick McHardy states:
I now understand whats happening:
- new connection is allocated without helper
- connection is REDIRECTed to localhost
- nf_nat_setup_info adds NAT extension, but doesn't initialize it yet
- nf_conntrack_alter_reply performs a helper lookup based on the
new tuple, finds the SIP helper and allocates a helper extension,
causing reallocation because of too little space
- nf_nat_move_storage is called with the uninitialized nat extension
So your fix is entirely correct, thanks a lot :) ]

2.6.23-stable review patch. If anyone has any objections, please let us

------------------
From: Daniel Drake <[email protected]>
patch dec13c15445fec29ca9087890895718450e80b95 in mainline.
The CONFIG_SUSPEND changes in 2.6.23 caused a regression under certain
configuration conditions (SUSPEND=n, USB_AUTOSUSPEND=y) where all USB
device attributes in sysfs (idVendor, idProduct, ...) silently disappeared,
causing udev breakage and more.
The cause of this is that the /sys/.../power subdirectory is now only
created when CONFIG_PM_SLEEP is set, however, it should be created whenever
CONFIG_PM is set to handle the above situation. The following patch fixes
the regression.

[NET]: Corrects a bug in ip_rt_acct_read()
[ Upstream commit: 483b23ffa3a5f44767038b0a676d757e0668437e ]
It seems that stats of cpu 0 are counted twice, since
for_each_possible_cpu() is looping on all possible cpus, including 0
Before percpu conversion of ip_rt_acct, we should also remove the
assumption that CPU 0 is online (or even possible)

[ Upstream commit: 3660019e5f96fd9a8b7d4214a96523c0bf7b676d ]
The #ifdef's in arp_process() were not only a mess, they were also wrong
in the CONFIG_NET_ETHERNET=n and (CONFIG_NETDEV_1000=y or
CONFIG_NETDEV_10000=y) cases.
Since they are not required this patch removes them.
Also removed are some #ifdef's around #include's that caused compile
errors after this change.

[TCP]: Problem bug with sysctl_tcp_congestion_control function
[ Upstream commit: 5487796f0c9475586277a0a7a91211ce5746fa6a ]
sysctl_tcp_congestion_control seems to have a bug that prevents it
from actually calling the tcp_set_default_congestion_control
function. This is not so apparent because it does not return an error
and generally the /proc interface is used to configure the default TCP
congestion control algorithm. This is present in 2.6.18 onwards and
probably earlier, though I have not inspected 2.6.15--2.6.17.
sysctl_tcp_congestion_control calls sysctl_string and expects a successful
return code of 0. In such a case it actually sets the congestion control
algorithm with tcp_set_default_congestion_control. Otherwise, it returns the
value returned by sysctl_string. This was correct in 2.6.14, as sysctl_string
returned 0 on success. However, sysctl_string was updated to return 1 on
success around about 2.6.15 and sysctl_tcp_congestion_control was not updated.
Even though sysctl_tcp_congestion_control returns 1, do_sysctl_strategy
converts this return code to '0', so the caller never notices the error.

[CRYPTO] api: Fix potential race in crypto_remove_spawn

As it is crypto_remove_spawn may try to unregister an instance which is
yet to be registered. This patch fixes this by checking whether the
instance has been registered before attempting to remove it.
It also removes a bogus cra_destroy check in crypto_register_instance as
1) it's outside the mutex;
2) we have a check in __crypto_register_alg already.

[TCP]: Fix TCP header misalignment
[ Upstream commit: 21df56c6e2372e09c916111efb6c14c372a5ab2e ]
Indeed my previous change to alloc_pskb has made it possible
for the TCP header to be misaligned iff the MTU is not a multiple
of 4 (and less than a page). So I suspect the optimised IPsec
MTU calculation is giving you just such an MTU :)
This patch fixes it by changing alloc_pskb to make sure that
the size is at least 32-bit aligned. This does not cause the
problem fixed by the previous patch because max_header is always
32-bit aligned which means that in the SG/NOTSO case this will
be a no-op.
I thought about putting this in the callers but all the current
callers are from TCP. If and when we get a non-TCP caller we
can always create a TCP wrapper for this function and move the
alignment over there.

When the abstraction functions got added, conversion here was

to skb which got included to the probe skb and then was freed.
For it to trigger, however, skb_transmit must fail sending as

[ Upstream commit: d31c7b8fa303eb81311f27b80595b8d2cbeef950 ]
Avaid provided test application, so bug got fixed.
IPv6 addrconf removes ipv6 inner device from netdev each time cmu
changes and new value is less than IPV6_MIN_MTU (1280 bytes).
When mtu is changed and new value is greater than IPV6_MIN_MTU,
it does not add ipv6 addresses and inner device bac.
This patch fixes that.

[TCP] illinois: Incorrect beta usage

Lachlan Andrew observed that my TCP-Illinois implementation uses the
beta value incorrectly:
The parameter beta in the paper specifies the amount to decrease
*by*: that is, on loss,
W <- W - beta*W
but in tcp_illinois_ssthresh() uses beta as the amount
to decrease *to*: W <- beta*W
This bug makes the Linux TCP-Illinois get less-aggressive on uncongested network,
hurting performance. Note: since the base beta value is .5, it has no
impact on a congested network.

If you try it, make sure /tmp/foobar_testsock doesn't exist.
The marked recv() returns -1 (EAGAIN) on 2.6.23.9. Below you find a
patch that fixes that.

[NETFILTER]: fix forgotten module release in xt_CONNMARK and xt_CONNSECMARK
[ Upstream commit: 67b4af297033f5f65999885542f95ba7b562848a ]
Fix forgotten module release in xt_CONNMARK and xt_CONNSECMARK
When xt_CONNMARK is used outside the mangle table and the user specified
"--restore-mark", the connmark_tg_check() function will (correctly)
error out, but (incorrectly) forgets to release the L3 conntrack module.
Same for xt_CONNSECMARK.
Fix is to move the call to acquire the L3 module after the basic
constraint checks.

2.6.23-stable review patch. If anyone has any objections, please let us

------------------
From: Tejun Heo <[email protected]>
patch 459ad68893a84fb0881e57919340b97edbbc3dc7 in mainline.
Spurious NCQ completion detection implemented in ahci was incorrect.
On AHCI receving and processing FISes and raising interrupts are not
interlocked and spurious interrupts are expected.
For example, if an interrupt occurs while interrupt handler is running
and the running interrupt handler handles the event the new IRQ
indicated, after IRQ handler finishes, it will be executed again
because IRQ pending bit is set by the new interrupt but there won't be
anything to process.
Please read the following message for more information.
http://article.gmane.org/gmane.linux.ide/26012
This patch...
* Removes all spurious IRQ whining from ahci. Spurious NCQ completion
detection was completely wrong. Spurious D2H Register FIS taught us
that some early drives send spurious D2H Register FIS with I bit set
while NCQ commands are in progress but none of recent drives does
that and even the ones which show such behavior can do NCQ fine.
* Kills all NCQ blacklist entries which were added because of spurious
NCQ completions. I tracked down each commit and verified all
removed ones are actually added because of spurious completions.
WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive
not only had spurious NCQ completions but also is slow on sequential
data transfers if NCQ is enabled.
Maxtor 7V300F0 was added by 0e3dbc01d53940fe10e5a5cfec15ede3e929c918
from Alan Cox. I can only find evidences that the drive only had
troubles with spuruious completions by searching the mailing list.
This entry needs to be verified and removed if it doesn't have other
NCQ related problems.

[XFRM]: Fix leak of expired xfrm_states
[ Upstream commit: 5dba4797115c8fa05c1a4d12927a6ae0b33ffc41 ]
The xfrm_timer calls __xfrm_state_delete, which drops the final reference
manually without triggering destruction of the state. Change it to use
xfrm_state_put to add the state to the gc list when we're dropping the
last reference. The timer function may still continue to use the state
safely since the final destruction does a del_timer_sync().

Please drop this one... I think I have seen a report where it
interferes with a regular logitech mouse. I will see if I fix it for
.24 or revert if from mainline. Definitely not for stable.

Hi Greg,
Do you think it might be possible to add the subjects of the patches
next time in the announcement? This would give people an easy way
(besides the diffstat) to check what is getting fixed.

The subject of the individual patches are in the email thread that is
attached to this announcement, so it should be quite simple to get this
information by just looking in your mail reader :)
Also, it would be hard to do this, unless someone has a patch to quilt
to provide this kind of information?
thanks,

Greg,
I think nowadays most people that read lkml use lkml.org or comparable
services. And lkml.org does not show the subject in the thread list.
But, well, I guess that's more of an issue for lkml.org to do something
about because it really is about navigating mail threads.
and... -ENOPATCH for quilt.
So no more comments from me and I go in search of a different webservice
that allows to read lkml with mail subjects in the navigation.

Right, but it shows them on the per-day overview.
