ila: ipv6/ila: fix nlsize calculation for lwtunnel

2016-05-10T20:00:25+00:00

The handler 'ila_fill_encap_info' adds two attributes: ILA_ATTR_LOCATOR
and ILA_ATTR_CSUM_MODE.

nla_total_size_64bit() must be use for ILA_ATTR_LOCATOR.

Also, do nla_put_u8 instead of nla_put_u64 for ILA_ATTR_CSUM_MODE.

Fixes: f13a82d87b21 ("ipv6: use nla_put_u64_64bit()")
Fixes: 90bfe662db13 ("ila: add checksum neutral ILA translations")

ila: add checksum neutral ILA translations

2016-04-26T05:27:07+00:00

Support checksum neutral ILA as described in the ILA draft. The low
order 16 bits of the identifier are used to contain the checksum
adjustment value.

The csum-mode parameter is added to described checksum processing. There
are three values:
 - adjust transport checksum (previous behavior)
 - do checksum neutral mapping
 - do nothing

On output the csum-mode in the ila_params is checked and acted on. If
mode is checksum neutral mapping then to mapping and set C-bit.

On input, C-bit is checked. If it is set checksum-netural mapping is
done (regardless of csum-mode in ila params) and C-bit will be cleared.
If it is not set then action in csum-mode is taken.

ila: xlat changes

2016-04-26T05:26:04+00:00

Change model of xlat to be used only for input where lookup is done on
the locator part of an address (comparing to locator_match as key
in rhashtable). This is needed for checksum neutral translation
which obfuscates the low order 16 bits of the identifier. It also
permits hosts to be in muliple ILA domains (each locator can map
to a different SIR address). A check is also added to disallow
translating non-ILA addresses (check of type in identifier).

ila: Add struct definitions and helpers

2016-04-26T05:25:22+00:00

Add structures for identifiers, locators, and an ila address which
is composed of a locator and identifier and in6_addr can be cast to
it. This includes a three bit type field and enums for the types defined
in ILA I-D.

In ILA lwt don't allow user to set a translation for a non-ILA
address (type of identifier is zero meaning it is an IID). This also
requires that the destination prefix is at least 65 bytes (64
bit locator and first byte of identifier).

rhashtable: accept GFP flags in rhashtable_walk_init

2016-04-05T08:56:32+00:00

In certain cases, the 802.11 mesh pathtable code wants to
iterate over all of the entries in the forwarding table from
the receive path, which is inside an RCU read-side critical
section.  Enable walks inside atomic sections by allowing
GFP_ATOMIC allocations for the walker state.

Change all existing callsites to pass in GFP_KERNEL.

ila: autoload module

Avoid users having to manually load the module by adding a module
alias allowing it to be autoloaded by the lwt infra.

ila: Add generic ILA translation facility

2015-12-16T04:25:20+00:00

This patch implements an ILA tanslation table. This table can be
configured with identifier to locator mappings, and can be be queried
to resolve a mapping. Queries can be parameterized based on interface,
direction (incoming or outoing), and matching locator.  The table is
implemented using rhashtable and is configured via netlink (through
"ip ila .." in iproute).

The table may be used as alternative means to do do ILA tanslations
other than the lw tunnels
