We have recently discovered that Tavor mode requires each WQE in a
posted list of receive WQEs to have a valid NDA field at all times.
This requirement holds true for regular QPs as well as for SRQs. This
patch prelinks the receive queue in a regular QP and keeps the free
list in SRQ always properly linked.

When a host just goes away (crash, power loss, etc.) without tearing
down its IB connections, it can get stale connection errors when it
tries to reconnect to targets upon rebooting. Retrying the connection
a few times will prevent sysadmins from playing the "which disk(s)
went missing?" game.
This would have made things slightly quicker when tracking down some
of the recent bugs, but it also helps quite a bit when you've got a
large number of targets hanging off a wedged server.

In mthca_reg_phys_mr(), we calculate the page size for the HCA
hardware to use to map the buffer list passed in by the consumer.
For example, if the consumer passes in
[0] addr 0x1000, size 0x1000
[1] addr 0x2000, size 0x1000
then the algorithm would come up with a page size of 0x2000 and a list
of two pages, at 0x0000 and 0x2000. Usually, this would work fine
since the memory region would start at an offset of 0x1000 and have a
length of 0x2000.
However, the old code did not take into account the alignment of the
IO virtual address passed in. For example, if the consumer passed in
a virtual address of 0x6000 for the above, then the offset of 0x1000
would not be used correctly because the page mask of 0x1fff would
result in an offset of 0.
We can fix this quite neatly by making sure that the page shift we use
is no bigger than the first bit where the start of the first buffer
and the IO virtual address differ. Also, we can further simplify the
code by removing the special case for a single buffer by noticing that
it doesn't matter if we use a page size that is too big. This allows
the loop to compute the page shift to be replaced with __ffs().

Currently early kernel messages, i.e., those from uncompression, go to the

status change. Besides, having those messages on another UART - typically
the console UART - may be preferrable. This patch allows selecting the

After discussions with Anthony Liguori, it seems that the virtio
balloon can be made even simpler. Here's my attempt.
The device configuration tells the driver how much memory it should
take from the guest (ie. balloon size). The guest feeds the page
numbers it has taken via one virtqueue.
A second virtqueue feeds the page numbers the driver wants back: if
the device has the VIRTIO_BALLOON_F_MUST_TELL_HOST bit, then this
queue is compulsory, otherwise it's advisory (and the guest can simply
fault the pages back in).
This driver can be enhanced later to deflate the balloon via a
shrinker, oom callback or we could even go for a complete set of
in-guest regulators.

Currently virtio_blk creates the disk name combinging "vd" with 'a'++.

There is one driver in the kernel (driver/s390/block/dasd_genhd.c) that

currently virtio_blk uses one major number per device. While this works

Anthony Liguori found double interrupt suppression in the virtio_net
driver, triggered by two skb_recv_done's in a row. This is because
virtio_ring's interrupt suppression is a best-effort optimization: it
contains no synchronization so the host can miss it and still send
interrupts.
But it's certainly nicer for virtio users if calling disable_cb
actually disables callbacks, so we check for the race in the interrupt
routine.
Note: SMP guests might require syncronization here, but since
disable_cb is actually called from interrupt context, there has to be
some form of synchronization before the next same interrupt handler is
called (Linux guarantees that the same device's irq handler will never
run simultanously on multiple CPUs).

A reset function solves three problems:
1) It allows us to renegotiate features, eg. if we want to upgrade a
guest driver without rebooting the guest.
2) It gives us a clean way of shutting down virtqueues: after a reset,
we know that the buffers won't be used by the host, and
3) It helps the guest recover from messed-up drivers.
So we remove the ->shutdown hook, and the only way we now remove
feature bits is via reset.
We leave it to the driver to do the reset before it deletes queues:
the balloon driver, for example, needs to chat to the host in its
remove function.

Building the aic7xxx driver includes the copy
of an .h file from a _shipped file.
In a highly parallel build Ingo saw that the
build sometimes failed (included distcc usage).
It was tracked down to a missing dependency from the .c
source file to the generated .h file.
We started to build the .c file before the
copy (cat) operation of the .h file completed
and we then only got half of the definitions
from the copied .h file.
Add an explicit dependency from the .c files to the
generated .h files so make knows all dependencies and
finsih the build of the .h files before it starts
building the .o files.
Ingo tested this fix and reported:
good news: hundreds of successful kernel builds and no failures
overnight.

* Change spin locks to mutex locks
* Add a BUG_ON() to phy_read() phy_write() to warn against
calling them from an interrupt context.
* Use work queue for PHY state machine handling since
it can potentially sleep

The driver should inform the stack when checksum has been performed by
the HW when both IP and TCP (or UDP) checksum flags are indicated by HW.
Previously, it would also inform the stack when only IP checksum flag
was indicated by HW. This can cause data corruption when IP fragments
are used. The IP Identification field can wrap around and cause data
from new fragments to fill into older fragment slots with same IP Id.
The stack would then not perform TCP/UDP checksum (after re-assembly of
all fragments) since driver falsely stated it was already calculated.

The ARP monitor functions currently acquire RTNL when performing

failing over in the ARP monitor.

I've seen reports of invalid stats in /proc/net/dev for bonding
interfaces, and found it's a pretty easy problem to reproduce. Since
the current code zeros the bonding stats when a read is requested and a
pointer to that data is returned to the caller we cannot guarantee that
the caller has completely accessed the data before a successive call to
request the stats zeroes the stats again.
This patch creates a new stack variable to keep track of the updated
stats and copies the data from that variable into the bonding stats
structure. This ensures that the value for any of the bonding stats
should not incorrectly return zero for any of the bonding statistics.
This does use more stack space and require an extra memcpy, but it seems
like a fair trade-off for consistently correct bonding statistics.

Subject: [PATCH, REPOST] Fix/Rewrite of the mipsnet driver
Content-Type: text/plain; charset=us-ascii
Hello All,
currently the mipsnet driver fails after transmitting a number of
packages because SKBs are allocated but never freed. I fixed that
and coudn't refrain from removing the most egregious warts.
- mipsnet.h folded into mipsnet.c, as it doesn't provide any
useful external interface.
- Free SKB after transmission.
- Call free_irq in mipsnet_close, to balance the request_irq in
mipsnet_open.
- Removed duplicate read of rxDataCount.
- Some identifiers are now less verbose.
- Removed dead and/or unnecessarily complex code.
- Code formatting fixes.
Tested on Qemu's mipssim emulation, with this patch it can boot a
Debian NFSroot.

[PATCH] s2io LRO bugs.
a) initiate_new_session() sets ->tcp_ack to ntohl(...); everything
else stores and expects to find there the net-endian value.
b) check for monotonic timestamps in verify_l3_l4_lro_capable()
compares the value sitting in TCP option (right there in the skb->data,
net-endian 32bit) with the value picked from earlier packet.
Doing that without ntohl() is an interesting idea and it might even
work occasionally; unfortunately, it's quite broken.

So to avoid wasting too much memory in the non-hotplug

use code/data from the __devinit sections.
This was done in all four case by adding the __ref
annotation.

Fix following warnings:
WARNING: o-x86_64/drivers/pci/built-in.o(.text+0xb054): Section mismatch in reference from the function cpci_configure_slot() to the function .devinit.text:pci_do_scan_bus()
WARNING: o-x86_64/drivers/pci/built-in.o(.text+0x153ab): Section mismatch in reference from the function shpchp_configure_device() to the function .devinit.text:pci_do_scan_bus()
WARNING: o-x86_64/drivers/pci/built-in.o(__ksymtab+0xc0): Section mismatch in reference from the variable __ksymtab_pci_do_scan_bus to the function .devinit.text:pci_do_scan_bus()
PCI hotplug were the only user of pci_do_scan_bus()
so moving this function to a separate file that is build
only when we enable CONFIG_HOTPLUG_PCI.

This reverts commit 6c723d5bd8.
It caused build errors on non-x86 platforms, config file confusion, and
even some boot errors on some x86-64 boxes. All around, not quite ready
for prime-time :(

Since this is used only in idetape_blkdev_ioctl(), remove the typedef and make
the struct function-local.

All those 2-byte values denoting the different capabilities are being written to
the local copy of the caps buffer without being converted to big endian for
simplicity of usage and shorter code later. Also, we add some comments stating
which are the fields of the caps page in question in order to alleviate the
cryptic pointer casting exercises as in e.g. idetape_get_mode_sense_results().
