genetlink: start to validate reserved header bytes

2022-08-29T11:47:15Z

We had historically not checked that genlmsghdr.reserved is 0 on input which prevents us from using those precious bytes in the future. One use case would be to extend the cmd field, which is currently just 8 bits wide and 256 is not a lot of commands for some core families. To make sure that new families do the right thing by default put the onus of opting out of validation on existing families.

batman-adv: Fix hang up with small MTU hard-interface

2022-08-20T12:17:45Z

The system hangs up when batman-adv soft-interface is created on hard-interface with small MTU. For example, the following commands create batman-adv soft-interface on dummy interface with zero MTU: # ip link add name dummy0 type dummy # ip link set mtu 0 dev dummy0 # ip link set up dev dummy0 # ip link add name bat0 type batadv # ip link set dev dummy0 master bat0 These commands cause the system hang up with the following messages: [ 90.578925][ T6689] batman_adv: bat0: Adding interface: dummy0 [ 90.580884][ T6689] batman_adv: bat0: The MTU of interface dummy0 is too small (0) to handle the transport of batman-adv packets. Packets going over this interface will be fragmented on layer2 which could impact the performance. Setting the MTU to 1560 would solve the problem.

batman-adv: Drop initialization of flexible ethtool_link_ksettings

2022-08-20T07:40:51Z

The commit 94dfc73e7cf4 ("treewide: uapi: Replace zero-length arrays with flexible-array members") changed various structures from using 0-length arrays to flexible arrays net/batman-adv/bat_v_elp.c: note: in included file: ./include/linux/ethtool.h:148:38: warning: nested flexible array net/batman-adv/bat_v_elp.c:128:9: warning: using sizeof on a flexible structure In theory, this could be worked around by using {} as initializer for the variable on the stack. But this variable doesn't has to be initialized at all by the caller of __ethtool_get_link_ksettings - everything will be initialized by the callee when no error occurs.

batman-adv: Drop unused headers in trace.h

2022-08-17T10:10:43Z

The commit 9abc291812d7 ("batman-adv: tracing: Use the new __vstring() helper") removed the usage of WARN_ON_ONCE and __dynamic_array in this file. But it was forgotten to adjust the headers accordingly (dropping the now no longer used ones). Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Start new development cycle

2022-08-17T10:09:21Z

This version will contain all the (major or even only minor) changes for Linux 6.1. The version number isn't a semantic version number with major and minor information. It is just encoding the year of the expected publishing as Linux -rc1 and the number of published versions this year (starting at 0). Signed-off-by: Simon Wunderlich

batman-adv: tracing: Use the new __vstring() helper

2022-07-30T17:52:47Z

Instead of open coding a __dynamic_array() with a fixed length (which defeats the purpose of the dynamic array in the first place). Use the new __vstring() helper that will use a va_list and only write enough of the string into the ring buffer that is needed.

net: wrap the wireless pointers in struct net_device in an ifdef

2022-05-22T20:51:54Z

Most protocol-specific pointers in struct net_device are under a respective ifdef. Wireless is the notable exception. Since there's a sizable number of custom-built kernels for datacenter workloads which don't build wireless it seems reasonable to ifdefy those pointers as well. While at it move IPv4 and IPv6 pointers up, those are special for obvious reasons.
