ADD-IP spec requires AUTH. It is, in fact, dangerous without AUTH.
So, disable ADD-IP functionality if the peer claims to support
ADD-IP, but not AUTH.Signed-off-by: Vlad Yasevich

Add SCTP-AUTH API. The API implemented here was

SCTP-AUTH, Section 6.2:
Endpoints MUST send all requested chunks authenticated where this has
been requested by the peer. The other chunks MAY be sent
authenticated or not. If endpoint pair shared keys are used, one of
them MUST be selected for authentication.To send chunks in an authenticated way, the sender MUST include these
chunks after an AUTH chunk. This means that a sender MUST bundle
chunks in order to authenticate them.If the endpoint has no endpoint pair shared key for the peer, it MUST
use Shared Key Identifier 0 with an empty endpoint pair shared key.
If there are multiple endpoint shared keys the sender selects one and
uses the corresponding Shared Key IdentifierSigned-off-by: Vlad Yasevich

Implement processing for the CHUNKS, RANDOM, and HMAC parameters and
deal with how this parameters are effected by association restarts.
In particular, during unexpeted INIT processing, we need to reply with
parameters from the original INIT chunk. Also, after restart, we need
to update the old association with new peer parameters and change the
association shared keys.Signed-off-by: Vlad Yasevich

Background: RFC 4293 deprecates existing individual, named ICMP
type counters to be replaced with the ICMPMsgStatsTable. This table
includes entries for both IPv4 and IPv6, and requires counting of all
ICMP types, whether or not the machine implements the type.These patches "remove" (but not really) the existing counters, and
replace them with the ICMPMsgStats tables for v4 and v6.
It includes the named counters in the /proc places they were, but gets the
values for them from the new tables. It also counts packets generated
from raw socket output (e.g., OutEchoes, MLD queries, RA's from
radvd, etc).Changes:
1) create icmpmsg_statistics mib
2) create icmpv6msg_statistics mib
3) modify existing counters to use these
4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types
listed by number for easy SNMP parsing
5) modify /proc/net/snmp printing for "Icmp" to get the named data
from new counters.Signed-off-by: David L Stevens

Thanks for noticing the bug where csum_start is not updated
when the head room changes.This patch fixes that. It also moves the csum/ip_summed
copying into copy_skb_header so that skb_copy_expand gets
it too. I've checked its callers and no one should be upset
by this.Signed-off-by: Herbert Xu

I was looking at Patrick's fix to inet_diag and it occured
to me that we're using a pointer argument to return values
unnecessarily in netlink_run_queue. Changing it to return
the value will allow the compiler to generate better code

The call_netdev_notifiers routine can successfully be used in

The bulk of the CIPSO option parsing/processing in the cipso_v4_sock_getattr()
and cipso_v4_skb_getattr() functions are identical, the only real difference
being where the functions obtain the CIPSO option itself. This patch creates
a new function, cipso_v4_getattr(), which contains the common CIPSO option
parsing/processing code and modifies the existing functions to call this new
helper function.Signed-off-by: Paul Moore

For the operations
get-tx-csum
get-sg
get-tso
get-ufo
the default ethtool_op_xxx behavior is fine for all drivers, so we
permit op==NULL to imply the default behavior.This provides a more uniform behavior across all drivers, eliminating
ethtool(8) "ioctl not supported" errors on older drivers that had
not been updated for the latest sub-ioctls.The ethtool_op_xxx() functions are left exported, in case anyone
wishes to call them directly from a driver-private implementation --
a not-uncommon case. Should an ethtool_op_xxx() helper remain unused
for a while, except by net/core/ethtool.c, we can un-export it at a
later date.[ Resolved conflicts with set/get value ethtool patch... -DaveM ]

We now have struct net_device_stats embedded in struct net_device,
and the default ->get_stats() hook does the obvious thing for us.Run through drivers/net/* and remove the driver-local storage of
statistics, and driver-local ->get_stats() hook where applicable.This was just the low-hanging fruit in drivers/net; plenty more drivers

- Code Optimization of s2io_isr function.
- Isr check using per device napi variable instead of driver global.
- Reduced from 3 to 1 if condition before check for processing packet receive
packets.
- Implemented Jeff's comment to use synchronize_irq. Removed the isr_cnt
variable as it became redundant.
- One time de assert the interrupts by writing all F's to the general_int_mask
register instead of de asserting by clearing the source of interrupts with
multiple writes which causes loss of interrupts (race conditions). It is
entirely possible that before the driver has a chance to mask the asserted
alarm bit, another alarm/traffic interrupt bit gets asserted as well. In
this case Herc will keep the INTA line asserted and the bridge will not
send a new Assert_INTA message upstream.[ Resolved conflicts due to napi_struct changes... -DaveM ]

- Added support to poll entire set of device errors and alarams.
- A note on how device errors and alarms are handled:
- The adapter will automatically recover from uncorrectable ECC errors.
Packets containing corrupted data will be dropped (not transmitted) or tagged
as invalid before being passed to the host.
- The adapter cannot recover from any internal state machine errors. A state
machine error requires a device reset.
- Any internal error that could potentially result in .store trampling.
(undesirable PCI behaviour)is tagged as a "serious error". In such cases
the adapter will give up its ability to be a bus master. In this situation
the host will still be able to read internal device registers in order to
generate an error report. A device reset is necessary to return to normal
operation.
- In the event of a pcix data parity error, the adapter will automatically
disable itself. Adapter_En will automatically transition from '1' to '0' and
the adapter will enter its clean-up routine. Once the device has achieved
quiescence, an adapter reset should be performed.
- Replaced alarm_intr_handler() with s2io_handle_errors().
- Added statistic counters to monitor the alarms.[ Fix warnings wrt. do_s2io_chk_alarm_bit(), Callers pass in an
"unsigned long long *" but the function takes a "u64 *" which is
different on many 64-bit platforms. -DaveM ]Signed-off-by: Sivakumar Subramani

- Added support to unmask entire set of device errors and alarams.
Alarm interrupts are generated for a myriad of purposes, ranging from
illegal operations or requests to internal state machine errors and
uncorrectable data corruption errors. In several cases the adapter can
recover gracefully from unexpected events; however, in some cases, a device
reset may be necessary. This patch handles alarms generated by all the
blocks within the device.The adapter generates the following types of alarms:
1. Link state transitions (local/remote fault) or other link-related
problems.
2. Problems with any device peripherals, including the EEPROM, FLASH,
etc.
3. Correctable ECC errors (single-bit errors) on internal data
structures or frame data.
4. Uncorrectable ECC errors (multi-bit errors) on internal data
structures or frame data.
5. State machine errors, which indicate that internal control
structures have become corrupted.
6. PCI related errors, including parity errors or illegal transactions.
7. Other unexpected events.- Implemented Jeff's review comments to use do_s2io_write_bits function to avoid
duplicate codes.Signed-off-by: Sivakumar Subramani
