6lowpan: debugfs: add missing static

2016-03-10T18:51:29+00:00

This patch solves the sparse warning: net/6lowpan/debugfs.c:164:30: warning: symbol 'lowpan_ctx_pfx_fops' was not declared. Should it be static? net/6lowpan/debugfs.c:241:30: warning: symbol 'lowpan_context_fops' was not declared. Should it be static? Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: iphc: fix invalid case handling

2016-02-26T08:08:15+00:00

This patch fixes the return value in a case which should never occur. Instead returning "-EINVAL" we return LOWPAN_IPHC_DAM_00 which is invalid on context based addresses. Also change the WARN_ON_ONCE to WARN_ONCE which was suggested by Dan Carpenter. Reported-by: Dan Carpenter Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: fix error checking code

2016-02-24T15:16:04+00:00

Bool variable 'fail' is always non-negative, it indicates an error if it is true. The problem has been detected using coccinelle script scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci Signed-off-by: Andrzej Hajda Acked-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: iphc: fix stateful multicast compression

2016-02-24T15:14:30+00:00

In case of multicast address we need to set always the LOWPAN_IPHC_M bit and if a destination context identifier was found for a multicast address then we need to set the LOWPAN_IPHC_DAC as well. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: iphc: add support for stateful compression

2016-02-23T19:29:40+00:00

This patch introduce support for IPHC stateful address compression. It will offer the context table via one debugfs entry. This debugfs has and directory for each cid entry for the context table. Inside each cid directory there exists the following files: - "active": If the entry is added or deleted. The context table is original a list implementation, this flag will indicate if the context is part of list or not. - "prefix": The ipv6 prefix. - "prefix_length": The prefix length for the prefix. - "compression": The compression flag according RFC6775. This part should be moved into sysfs after some testing time. Also the debugfs entry contains a "show" file which is a pretty-printout for the current context table information.

6lowpan: fix debugfs interface entry name

2015-12-20T07:21:00+00:00

This patches moves the debugfs interface related register after netdevice register. The function lowpan_dev_debugfs_init will use "dev->name" which can be before register_netdevice a format string. The function register_netdevice will evaluate the format string if necessary and replace "dev->name" to the real interface name.

6lowpan: add debugfs support

2015-12-10T00:25:25+00:00

This patch will introduce a 6lowpan entry into the debugfs if enabled. Inside this 6lowpan directory we create a subdirectories of all 6lowpan interfaces to offer a per interface debugfs support. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

6lowpan: add lowpan dev register helpers

2015-12-10T00:25:25+00:00

This patch introduces register and unregister functionality for lowpan interfaces. While register a lowpan interface there are several things which need to be initialize by the 6lowpan subsystem. Upcoming functionality need to register/unregister per interface components e.g. debugfs entry. Reviewed-by: Stefan Schmidt Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann
