inet: frag: change *_frag_mem_limit functions to take netns_frags as argument

2015-07-27T04:00:14+00:00

Followup patch will call it after inet_frag_queue was freed, so q->net doesn't work anymore (but netf = q->net; free(q); mem_limit(netf) would). Tested-by: Frank Schreuder Signed-off-by: Florian Westphal Signed-off-by: David S. Miller

nl802154: export supported commands

2015-06-04T10:27:15+00:00

This patch will export the supported commands by the devices to the userspace. This will be useful to check if HardMAC drivers can support a specific command or not. Signed-off-by: Varka Bhadram Acked-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: Fix sockaddr_ieee802154 implicit padding information leak.

2015-06-04T10:26:58+00:00

The AF_IEEE802154 sockaddr looks like this: struct sockaddr_ieee802154 { sa_family_t family; /* AF_IEEE802154 */ struct ieee802154_addr_sa addr; }; struct ieee802154_addr_sa { int addr_type; u16 pan_id; union { u8 hwaddr[IEEE802154_ADDR_LEN]; u16 short_addr; }; }; On most architectures there will be implicit structure padding here, in two different places: * In struct sockaddr_ieee802154, two bytes of padding between 'family' (unsigned short) and 'addr', so that 'addr' starts on a four byte boundary. * In struct ieee802154_addr_sa, two bytes at the end of the structure, to make the structure 16 bytes. When calling recvmsg(2) on a PF_IEEE802154 SOCK_DGRAM socket, the ieee802154 stack constructs a struct sockaddr_ieee802154 on the kernel stack without clearing these padding fields, and, depending on the addr_type, between four and ten bytes of uncleared kernel stack will be copied to userspace. We can't just insert two 'u16 __pad's in the right places and zero those before copying an address to userspace, as not all architectures insert this implicit padding -- from a quick test it seems that avr32, cris and m68k don't insert this padding, while every other architecture that I have cross compilers for does insert this padding. The easiest way to plug the leak is to just memset the whole struct sockaddr_ieee802154 before filling in the fields we want to fill in, and that's what this patch does.

ieee802154: 6lowpan: set ackreq when needed

2015-06-02T15:09:35+00:00

This patch sets the acknowledge request bit inside the 802.15.4 mac header when frame retries is 0 or above. The other frame retries value which is -1 indicates that the transmitter doesn't care about an acknowledge frame which will be ignored after transmitting if the node sends anyway an ack frame after receiving. This is currently unnecessary traffic if the max frame retries parameter is -1. Signed-off-by: Alexander Aring Reviewed-by: Stefan Schmidt Signed-off-by: Marcel Holtmann
