pci_unmap_sg(struct pci_dev *hwdev, struct scatterlist *sg,

With scatterlists, you use the resulting mapping like this:
int i, count = dma_map_sg(dev, sglist, nents, direction);
struct scatterlist *sg;
for (i = 0, sg = sglist; i < count; i++, sg++) {
hw_address[i] = sg_dma_address(sg);
hw_len[i] = sg_dma_len(sg);
}
where nents is the number of entries in the sglist.
The implementation is free to merge several consecutive sglist entries
into one (e.g. with an IOMMU, or if several pages just happen to be
physically contiguous) and returns the actual number of sg entries it
mapped them to. On failure 0, is returned.
Then you should loop count times (note: this can be less than nents times)
and use sg_dma_address() and sg_dma_len() macros where you previously
accessed sg->address and sg->length as shown above.

This rule also means that you may use neither kernel image addresses

stack addresses for DMA. These could all be mapped somewhere entirely
different than the rest of physical memory. Even if those classes of
memory could physically work with DMA, you'd need to ensure the I/O
buffers were cacheline-aligned. Without that, you'd see cacheline
sharing problems (data corruption) on CPUs with DMA-incoherent caches.
(The CPU could write to one word, DMA would write to a different one
in the same cache line, and one of them could be overwritten.)
Also, this means that you cannot take the return of a kmap()
call and DMA to/from that. This is similar to vmalloc().

These devices use different pinout configurations, so you have to tell
the driver what you have, using the type module parameter. There is no
way to autodetect the devices. Support for different pinout configurations
can be easily added when needed.
Earlier kernels defaulted to type=0 (Philips). But now, if the type
parameter is missing, the driver will simply fail to initialize.

The sync patches work is based on initial patches from
Krisztian <hidden@balabit.hu> and others and additional patches
from Jamal <hadi@cyberus.ca>.
The end goal for syncing is to be able to insert attributes + generate
events so that the an SA can be safely moved from one machine to another
for HA purposes.
The idea is to synchronize the SA so that the takeover machine can do
the processing of the SA as accurate as possible if it has access to it.
We already have the ability to generate SA add/del/upd events.
These patches add ability to sync and have accurate lifetime byte (to
ensure proper decay of SAs) and replay counters to avoid replay attacks
with as minimal loss at failover time.
This way a backup stays as closely uptodate as an active member.
Because the above items change for every packet the SA receives,
it is possible for a lot of the events to be generated.
For this reason, we also add a nagle-like algorithm to restrict
the events. i.e we are going to set thresholds to say "let me
know if the replay sequence threshold is reached or 10 secs have passed"
These thresholds are set system-wide via sysctls or can be updated
per SA.
The identified items that need to be synchronized are:
- the lifetime byte counter
note that: lifetime time limit is not important if you assume the failover
machine is known ahead of time since the decay of the time countdown
is not driven by packet arrival.
- the replay sequence for both inbound and outbound
1) Message Structure
----------------------
nlmsghdr:aevent_id:optional-TLVs.
The netlink message types are:
XFRM_MSG_NEWAE and XFRM_MSG_GETAE.
A XFRM_MSG_GETAE does not have TLVs.
A XFRM_MSG_NEWAE will have at least two TLVs (as is
discussed further below).
aevent_id structure looks like:
struct xfrm_aevent_id {
struct xfrm_usersa_id sa_id;
__u32 flags;
};
xfrm_usersa_id in this message layout identifies the SA.
flags are used to indicate different things. The possible
flags are:
XFRM_AE_RTHR=1, /* replay threshold*/
XFRM_AE_RVAL=2, /* replay value */
XFRM_AE_LVAL=4, /* lifetime value */
XFRM_AE_ETHR=8, /* expiry timer threshold */
XFRM_AE_CR=16, /* Event cause is replay update */
XFRM_AE_CE=32, /* Event cause is timer expiry */
XFRM_AE_CU=64, /* Event cause is policy update */
How these flags are used is dependent on the direction of the
message (kernel<->user) as well the cause (config, query or event).
This is described below in the different messages.
The pid will be set appropriately in netlink to recognize direction
(0 to the kernel and pid = processid that created the event
when going from kernel to user space)
A program needs to subscribe to multicast group XFRMNLGRP_AEVENTS
to get notified of these events.
2) TLVS reflect the different parameters:
-----------------------------------------
a) byte value (XFRMA_LTIME_VAL)
This TLV carries the running/current counter for byte lifetime since
last event.
b)replay value (XFRMA_REPLAY_VAL)
This TLV carries the running/current counter for replay sequence since
last event.
c)replay threshold (XFRMA_REPLAY_THRESH)
This TLV carries the threshold being used by the kernel to trigger events
when the replay sequence is exceeded.
d) expiry timer (XFRMA_ETIMER_THRESH)
This is a timer value in milliseconds which is used as the nagle
value to rate limit the events.
3) Default configurations for the parameters:
----------------------------------------------
By default these events should be turned off unless there is
at least one listener registered to listen to the multicast
group XFRMNLGRP_AEVENTS.
Programs installing SAs will need to specify the two thresholds, however,
in order to not change existing applications such as racoon
we also provide default threshold values for these different parameters
in case they are not specified.
the two sysctls/proc entries are:
a) /proc/sys/net/core/sysctl_xfrm_aevent_etime
used to provide default values for the XFRMA_ETIMER_THRESH in incremental
units of time of 100ms. The default is 10 (1 second)
b) /proc/sys/net/core/sysctl_xfrm_aevent_rseqth
used to provide default values for XFRMA_REPLAY_THRESH parameter
in incremental packet count. The default is two packets.
4) Message types
----------------
a) XFRM_MSG_GETAE issued by user-->kernel.
XFRM_MSG_GETAE does not carry any TLVs.
The response is a XFRM_MSG_NEWAE which is formatted based on what
XFRM_MSG_GETAE queried for.
The response will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
*if XFRM_AE_RTHR flag is set, then XFRMA_REPLAY_THRESH is also retrieved
*if XFRM_AE_ETHR flag is set, then XFRMA_ETIMER_THRESH is also retrieved
b) XFRM_MSG_NEWAE is issued by either user space to configure
or kernel to announce events or respond to a XFRM_MSG_GETAE.
i) user --> kernel to configure a specific SA.
any of the values or threshold parameters can be updated by passing the
appropriate TLV.
A response is issued back to the sender in user space to indicate success
or failure.
In the case of success, additionally an event with
XFRM_MSG_NEWAE is also issued to any listeners as described in iii).
ii) kernel->user direction as a response to XFRM_MSG_GETAE
The response will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
The threshold TLVs will be included if explicitly requested in
the XFRM_MSG_GETAE message.
iii) kernel->user to report as event if someone sets any values or
thresholds for an SA using XFRM_MSG_NEWAE (as described in #i above).
In such a case XFRM_AE_CU flag is set to inform the user that
the change happened as a result of an update.
The message will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
iv) kernel->user to report event when replay threshold or a timeout
is exceeded.
In such a case either XFRM_AE_CR (replay exceeded) or XFRM_AE_CE (timeout
happened) is set to inform the user what happened.
Note the two flags are mutually exclusive.
The message will always have XFRMA_LTIME_VAL and XFRMA_REPLAY_VAL TLVs.
Exceptions to threshold settings
--------------------------------
If you have an SA that is getting hit by traffic in bursts such that
there is a period where the timer threshold expires with no packets
seen, then an odd behavior is seen as follows:
The first packet arrival after a timer expiry will trigger a timeout
aevent; i.e we dont wait for a timeout period or a packet threshold
to be reached. This is done for simplicity and efficiency reasons.

* sg_scsi_ioctl -- handle deprecated SCSI_IOCTL_SEND_COMMAND ioctl
* @file: file this ioctl operates on (optional)
* @q: request queue to send scsi commands down
* @disk: gendisk to operate on (option)
* @sic: userspace structure describing the command to perform
*
* Send down the scsi command described by @sic to the device below
* the request queue @q. If @file is non-NULL it's used to perform
* fine-grained permission checks that allow users to send down
* non-destructive SCSI commands. If the caller has a struct gendisk
* available it should be passed in as @disk to allow the low level
* driver to use the information contained in it. A non-NULL @disk
* is only allowed if the caller knows that the low level driver doesn't
* need it (e.g. in the scsi subsystem).
*
* Notes:
* - This interface is deprecated - users should use the SG_IO
* interface instead, as this is a more flexible approach to
* performing SCSI commands on a device.
* - The SCSI command length is determined by examining the 1st byte
* of the given command. There is no way to override this.
* - Data transfers are limited to PAGE_SIZE
* - The length (x + y) must be at least OMAX_SB_LEN bytes long to
* accommodate the sense buffer when an error occurs.
* The sense buffer is truncated to OMAX_SB_LEN (16) bytes so that
* old code will not be surprised.
* - If a Unix error occurs (e.g. ENOMEM) then the user will receive
* a negative return and the Unix error code in 'errno'.
* If the SCSI command succeeds then 0 is returned.
* Positive numbers returned are the compacted SCSI error codes (4
* bytes in one int) where the lowest byte is the SCSI status.

This driver is a replacement for (and was inspired by) an older
driver named i2c-philips-par. The new driver supports more devices,
and makes it easier to add support for new devices.
An adapter type parameter is now mandatory. Please read the file
Documentation/i2c/busses/i2c-parport for details.
Another driver exists, named i2c-parport-light, which doesn't depend
on the parport driver. This is meant for embedded systems. Don't say

---help---
Driver for S514-PCI/ISA Synchronous Data Link Adapters (SDLA).
WANPIPE from Sangoma Technologies Inc. <http://www.sangoma.com/>
is a family of intelligent multiprotocol WAN adapters with data
transfer rates up to 4Mbps. Cards support:
- X.25, Frame Relay, PPP, Cisco HDLC protocols.
- API for protocols like HDLC (LAPB), HDLC Streaming, X.25,
Frame Relay and BiSync.
- Ethernet Bridging over Frame Relay protocol.
- MULTILINK PPP
- Async PPP (Modem Dialup)
The next questions will ask you about the protocols you want
the driver to support.
If you have one or more of these cards, say M to this option;
and read <file:Documentation/networking/wan-router.txt>.
To compile this driver as a module, choose M here: the
module will be called wanpipe.

which allows user to build applications using the HDLC streaming API.
- CHDLC Streaming MULTILINK PPP that can bind multiple WANPIPE T1
cards into a single logical channel.
Say Y and the Cisco HDLC support, HDLC streaming API and
MULTILINK PPP will be included in the driver.
config WANPIPE_FR
