Revision 1d567e19cc9810a9bd67b1ccab54b68d86dadb76 authored by Linus Torvalds on 16 November 2012, 22:10:15 UTC, committed by Linus Torvalds on 16 November 2012, 22:10:15 UTC
Pull networking updates from David Miller: 1) tx_filtered/ps_tx_buf queues need to be accessed with the SKB queue lock, from Arik Nemtsov. 2) Don't call 802.11 driver's filter configure method until it's actually open, from Felix Fietkau. 3) Use ieee80211_free_txskb otherwise we leak control information. From Johannes Berg. 4) Fix memory leak in bluetooth UUID removal,f rom Johan Hedberg. 5) The shift mask trick doesn't work properly when 'optname' is out of range in do_ip_setsockopt(). Use a straightforward switch statement instead, the compiler emits essentially the same code but without the missing range check. From Xi Wang. 6) Fix when we call tcp_replace_ts_recent() otherwise we can erroneously accept a too-high tsval. From Eric Dumazet. 7) VXLAN bug fixes, mostly to do with VLAN header length handling, from Alexander Duyck. 8) Missing return value initialization for IPV6_MINHOPCOUNT socket option handling. From Hannes Frederic. 9) Fix regression in tasklet handling in jme/ksz884x/xilinx drivers, from Xiaotian Feng. 10) At smsc911x driver init time, we don't know if the chip is in word swap mode or not. However we do need to wait for the control register's ready bit to be set before we program any other part of the chip. Adjust the wait loop to account for this. From Kamlakant Patel. 11) Revert erroneous MDIO bus unregister change to mdio-bitbang.c 12) Fix memory leak in /proc/net/sctp/, from Tommi Rantala. 13) tilegx driver registers IRQ with NULL name, oops, from Simon Marchi. 14) TCP metrics hash table kzalloc() based allocation can fail, back down to using vmalloc() if it does. From Eric Dumazet. 15) Fix packet steering out-of-order delivery regression, from Tom Herbert. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (40 commits) net-rps: Fix brokeness causing OOO packets tcp: handle tcp_net_metrics_init() order-5 memory allocation failures batman-adv: process broadcast packets in BLA earlier batman-adv: don't add TEMP clients belonging to other backbone nodes batman-adv: correctly pass the client flag on tt_response batman-adv: fix tt_global_entries flags update tilegx: request_irq with a non-null device name net: correct check in dev_addr_del() tcp: fix retransmission in repair mode sctp: fix /proc/net/sctp/ memory leak Revert "drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister before mdiobus_free" net/smsc911x: Fix ready check in cases where WORD_SWAP is needed drivers/net: fix tasklet misuse issue ipv4/ip_vti.c: VTI fix post-decryption forwarding brcmfmac: fix typo in CONFIG_BRCMISCAN vxlan: Update hard_header_len based on lowerdev when instantiating VXLAN vxlan: fix a typo. ipv6: setsockopt(IPIPPROTO_IPV6, IPV6_MINHOPCOUNT) forgot to set return value doc/net: Fix typo in netdev-features.txt vxlan: Fix error that was resulting in VXLAN MTU size being 10 bytes too large ...

# headers_check.pl execute a number of trivial consistency checks
#
# Usage: headers_check.pl dir arch [files...]
# dir: dir to look for included files
# arch: architecture
# files: list of files to check
#
# The script reads the supplied files line by line and:
#
# 1) for each include statement it checks if the
# included file actually exists.
# Only include files located in asm* and linux* are checked.
# The rest are assumed to be system include files.
#
# 2) It is checked that prototypes does not use "extern"
#
# 3) Check for leaked CONFIG_ symbols
