When both ports are receiving simultaneously, the receive logic gets confused
and may pass up a packet before it is full. This causes hangs, and IP will see
lots of garbage packets. There is even the potential for data corruption if
a later arriving packet DMA's into freed memory.
It looks like a hardware bug because status arrives for a packet but no
data is there. Until this bug is worked out, block the user from bringing
up both ports at once.

three gigabit ports, but some enp2611 models only have two ports
(and only one onboard PM3386.) The current driver assumes there
are always three ports and so it doesn't work on the two-port
version of the board at all.
This patch adds a bit of logic to the enp2611 driver to limit the
number of ports to 2 if the second PM3386 isn't detected.

When we fail to mount from a valid root device list out the filesystems we
have tried to mount it with. This gives the user vital diagnostics as to
what is missing from their kernel.
For example in the fragment below the kernel does not have CRAMFS compiled
into the kernel and yet appears to recognise it at the RAMDISK detect
stage. Later the mount fails as we don't have the filesystem.
RAMDISK: cramfs filesystem found at block 0
RAMDISK: Loading 1604KiB [1 disk] into ram disk... done.
XFS: bad magic number

can_share_swap_page() is used to check if the page has the last reference.
This avoids allocating a new page for COW if it's the last page.
However, if CONFIG_SWAP is not set, can_share_swap_page() is defined as 0,
thus always causes a copy for the last COW page. The below simple patch
fixes it.

Yesterday, I got the following error with 2.6.16.13 during a file copy from
a smb filesystem over a wireless link. I guess there was some error on the
wireless link, which in turn caused an error condition for the smb
filesystem.
In the log, smb_file_read reports error=4294966784 (0xfffffe00), which also
shows up in the slab dumps, and also is -ERESTARTSYS. Error code 27499
corresponds to 0x6b6b, so the rq_errno field seems to be the only one being
set after freeing the slab.
In smb_add_request (which is the only place in smbfs where I found
ERESTARTSYS), I found the following:
if (!timeleft || signal_pending(current)) {
/*
* On timeout or on interrupt we want to try and remove the
* request from the recvq/xmitq.
*/
smb_lock_server(server);
if (!(req->rq_flags & SMB_REQ_RECEIVED)) {
list_del_init(&req->rq_queue);
smb_rput(req);
}
smb_unlock_server(server);
}
[...]
if (signal_pending(current))
req->rq_errno = -ERESTARTSYS;
I guess that some codepath like smbiod_flush() caused the request to be
removed from the queue, and smb_rput(req) be called, without
SMB_REQ_RECEIVED being set. This violates an asumption made by the quoted
code.
Then, the above code calls smb_rput(req) again, the req gets freed, and
req->rq_errno = -ERESTARTSYS writes into the already freed slab. As
list_del_init doesn't cause an error if called multiple times, that does
cause the observed behaviour (freed slab with rq_errno=-ERESTARTSYS).
If this observation is correct, the following patch should fix it.
I wonder why the smb code uses list_del_init everywhere - using list_del
instead would catch such situations by poisoning the next and prev
pointers.

Even since a previous patch:
Fix race between CONFIG_DEBUG_SLABALLOC and modules
Sun, 27 Jun 2004 17:55:19 +0000 (17:55 +0000)
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=92b3db26d31cf21b70e3c1eadc56c179506d8fbe
The function symbol_put_addr() will deadlock the kernel.
symbol_put_addr() would acquire modlist_lock, then while holding the lock call
two functions kernel_text_address() and module_text_address() which also try
to acquire the same lock. This deadlocks the kernel of course.
This patch changes symbol_put_addr() to not acquire the modlist_lock, it
doesn't need it since it never looks at the module list directly. Also, it
now uses core_kernel_text() instead of kernel_text_address(). The latter has
an additional check for addr inside a module, but we don't need to do that
since we call module_text_address() (the same function kernel_text_address
uses) ourselves.

While debugging why our LCS emulator is having some problems I noticed the
following weirdness in drivers/s390/net/lcs.c routine lcs_irq. The `if'
statement is always true since SCHN_STAT_PCI is defined as 0x80.

As pointed out in http://bugzilla.kernel.org/show_bug.cgi?id=6490, this
function can experience overflows on 32-bit machines, causing our response to
changed values of min_free_kbytes to go whacky.
Fixing it efficiently is all too hard, so fix it with 64-bit math instead.

With "Paul E. McKenney" <paulmck@us.ibm.com>
Introduce rcu_needs_cpu() interface. This can be used to tell if there
will be a new rcu batch on a cpu soon by looking at the curlist pointer.
This can be used to avoid to enter a tickless idle state where the cpu
would miss that a new batch is ready when rcu_start_batch would be called
on a different cpu.

Mark Moseley reported that a chroot environment on a SMB share can be left

smbfs.

An earlier commit (75cf7456dd) changed an
overly-zealous PCI quirk to only poke those VIA devices that need it.
However, some PCI devices were not included in what I hope is now the full
list. Consequently we're failing to run the quirk on all machines which need
it, causing IRQ routing failures.
This should I hope correct this.
Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out
and testing the fix.

I am having the bug FATAL: Error inserting capi ([..]/capi.ko): Device or
resource busy when I try to reload capi after loading it. in dmesg:
capi20: unable to get major 68
Fix the issue which is caused by setting the major to zero when registering
the chrdev succeeded.
(akpm: this means that we can again not use `major=0' (dynamic major
allocation) for this driver).

This patch fixes two problems.
First, the comparison of entries in the waitq.c was incorrect.
Second, the NFY_NONE check was incorrect. The test of whether the dentry
is mounted if ineffective, for example, if an expire fails then we could
wait forever on a non existant expire. The bug was identified by Jeff
Moyer.
The patch changes autofs4 to wait on expires only as this is all that's
needed. If there is no existing wait when autofs4_wait is call with a type
of NFY_NONE it delays until either a wait appears or the the expire flag is
cleared.

This reverts commit 10dbe196a8.
The resource struct is still 32-bit, so trying to save a 64-bit memory
size there obviously won't work.
When we merge the 64-bit resource series, we can re-enable this.

Make sure to clear the driverfs_dev pointer when we do del_gendisk() (on
disk removal), so that other users that may still have a ref to the disk
won't try to use the stale pointer.
Also move the KOBJ_REMOVE uevent handler up, so that the uevent still
has access to the driverfs_dev data.
This all should hopefully fix the problems with MMC umounts after device
removals that caused commit 56cf6504fc and
its reversal (1a2acc9e92).
Original problem reported by Todd Blumer and others.
