Allocate 128 bytes linear buffer for rx skb. The first 64 bytes is reserved for mac80211 usage (for radiotap header expansion, etc). The frame header starts from the second 64 bytes. Cc: Johannes Berg <johannes@sipsolutions.net> Signed-off-by:

Do not mess with the original skb, but allocate an independent bouncebuffer. This protects against bad interference with mac80211's assumptions about the skb (which already caused bugs). Signed-off-by:

This is similar to other cases where for_each_netdev_rcu can be used when gathering information. By inspection, don't have platform or cross-build environment to validate. Signed-off-by:

Do not need to use read_lock(&dev_base_lock), use RCU instead. Signed-off-by:

This adds an RCU macro for continuing search, useful for some network devices like vlan. Signed-off-by:

This patch rearranges the SIT DF bit handling using the new IPIP DF code. The only externally visible effect should be the case where PMTU is enabled and the MTU is exactly 1280 bytes. In this case the previous code would send packets out with DF off while the new code would set the DF bit. This is inline with RFC 4213. Signed-off-by:

Apparently, inet6_dump_addr() is not able to handle more than 64 ipv6 addresses per device. We must break from inner loops in case skb is full, or else cursor is put at the end of list. Signed-off-by:
-
Eric Dumazet authored
When handling large number of netdevice, inet6_dump_ifinfo() is very slow because it has O(N^2) complexity. Instead of scanning one single list, we can use the 256 sub lists of the dev_index hash table, and RCU lookups. Signed-off-by:

Some usbnet drivers update link state while others do not due to hardware limitations. Add a flag to distinguish those that do, and set the link down initially for their devices. This is intended to fix this bug: http://bugs.debian.org/444043Signed-off-by:

When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field in the HT Information Element to determine whether or not to use protection. The Operating Mode field has 4 possible settings: 0-3: Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT stations in a 20 MHz BSS Mode 1: used if there are non-HT stations or APs using the primary or secondary channels Mode 2: if only HT stations are associated in the BSS and at least one 20 MHz HT station is associated. Mode 3: used if one or more non-HT stations are associated in the BSS. When in operating modes 1 or 3, and the Use_Protection field is 1 in the Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or CTS-to-Self. By default, CTS-to-self is the preferred protection mechanism for less overhead and higher throughput; but using the full RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment. For 6000 series WIFI NIC, RTS/CTS protection mechanism is the recommended choice for HT traffic based on the HW design. Signed-off-by:
