I rework the debugfs entry for the stateful compression. Now each context entry for a 6LoWPAN contains has his own subdirectory (named as his CID value). In this subdirectories there exists the following files for manipulating the context entry: - active: If the context belongs to the table or not. - compression: the compression flag according rfc6775. - prefix: ipv6 prefix in xxxx:xxxx:....:xxxx form. - prefix_lenght: the length of the ipv6 prefix. This offers a setting per property instead doing remember the full context and doing echo "$FULL_CONTEXT_INFORMATION" > ctx_table. These file should be prepared to move into the sysfs directory when it seems to running fine. There exist one file "show" inside $LOWPAN_IFACE/contexts/. This file is for a "pretty-printout" for the current context table. I use the same format-string like RIOT-OS, example: cid|prefix |C ------------------------------------------------- 0| 2001::/64 |1 1| 2001::1/128|1 2| 2001::5/128|1 7| 2002::/64 |1 difference here is that RIOT shows the lifetime, but I currently see no sense to handle the lifetime in kernelspace. Also I added support to clean the context table when doing a "ifdown". The reason is that IPv6 interface will also drop all address information while doing a ifdown and a 6LoWPAN should not use previous context information after ifup again. - Alex Alexander Aring (2): 6lowpan: iphc: add support for stateful compression ieee802154: 6lowpan: fix return of netdev notifier include/net/6lowpan.h | 31 ++++ net/6lowpan/core.c | 39 +++- net/6lowpan/debugfs.c | 247 +++++++++++++++++++++++++ net/6lowpan/iphc.c | 420 ++++++++++++++++++++++++++++++++++++------ net/ieee802154/6lowpan/core.c | 7 +- 5 files changed, 682 insertions(+), 62 deletions(-) -- 2.6.1
