2006-12-02[DCCP]: Combine allocating & zeroing header space on skbGerrit Renker
This is a code simplification: it combines three often recurring operations into one inline function, * allocate `len' bytes header space in skb * fill these `len' bytes with zeroes * cast the start of this header space as dccp_hdr Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

2006-12-02[TCP]: Don't set SKB owner in tcp_transmit_skb().David S. Miller
The data itself is already charged to the SKB, doing the skb_set_owner_w() just generates a lot of noise and extra atomics we don't really need. Lmbench improvements on lat_tcp are minimal: before: TCP latency using localhost: 23.2701 microseconds TCP latency using localhost: 23.1994 microseconds TCP latency using localhost: 23.2257 microseconds after: TCP latency using localhost: 22.8380 microseconds TCP latency using localhost: 22.9465 microseconds TCP latency using localhost: 22.8462 microseconds Signed-off-by: David S.

2006-12-02[TCP]: Restrict congestion control choices.Stephen Hemminger
Allow normal users to only choose among a restricted set of congestion control choices. The default is reno and what ever has been configured as default. But the policy can be changed by administrator at any time. For example, to allow any choice: cp /proc/sys/net/ipv4/tcp_available_congestion_control \ /proc/sys/net/ipv4/tcp_allowed_congestion_control Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.

2006-12-02[SCTP]: Fix warningVlad Yasevich
An alternate solution would be to make the digest a pointer, allocate it in sctp_endpoint_init() and free it in sctp_endpoint_destroy(). I guess I should have originally done it this way... CC [M] net/sctp/sm_make_chunk.o net/sctp/sm_make_chunk.c: In function 'sctp_unpack_cookie': net/sctp/sm_make_chunk.c:1358: warning: initialization discards qualifiers from pointer target type The reason is that sctp_unpack_cookie() takes a const struct sctp_endpoint and modifies the digest in it (digest being embedded in the struct, not a pointer). Make digest a pointer to fix this warning. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Acked-by: Sridhar Samudrala <sri@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-12-02[NET]: Size listen hash tables using backlog hintEric Dumazet
We currently allocate a fixed size (TCP_SYNQ_HSIZE=512) slots hash table for each LISTEN socket, regardless of various parameters (listen backlog for example) On x86_64, this means order-1 allocations (might fail), even for 'small' sockets, expecting few connections. On the contrary, a huge server wanting a backlog of 50000 is slowed down a bit because of this fixed limit. This patch makes the sizing of listen hash table a dynamic parameter, depending of : - net.core.somaxconn tunable (default is 128) - net.ipv4.tcp_max_syn_backlog tunable (default : 256, 1024 or 128) - backlog value given by user application (2nd parameter of listen()) For large allocations (bigger than PAGE_SIZE), we use vmalloc() instead of kmalloc(). We still limit memory allocation with the two existing tunables (somaxconn & tcp_max_syn_backlog). So for standard setups, this patch actually reduce RAM usage.

2006-12-02[PKT_SCHED]: Make sch_fifo.o available when CONFIG_NET_SCHED is not set.David Kimdon
Based on patch by Patrick McHardy. Add a new option, NET_SCH_FIFO, which provides a simple fifo qdisc without requiring CONFIG_NET_SCHED. The d80211 stack needs a generic fifo qdisc for WME. At present it uses net/d80211/fifo_qdisc.c which is functionally equivalent to sch_fifo.c. This patch will allow the d80211 stack to remove net/d80211/fifo_qdisc.c and use sch_fifo.c instead.

2006-12-02[NET]: Rethink mark field in struct flowiThomas Graf
Now that all protocols have been made aware of the mark field it can be moved out of the union thus simplyfing its usage. The config options in the IPv4/IPv6/DECnet subsystems to enable respectively disable mark based routing only obfuscate the code with ifdefs, the cost for the additional comparison in the flow key is insignificant, and most distributions have all these options enabled by default anyway. Therefore it makes sense to remove the config options and enable mark based routing by default. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-02[NET]: Turn nfmark into generic markThomas Graf

2006-12-02SELinux: Fix SA selection semanticsVenkat Yekkirala
Fix the selection of an SA for an outgoing packet to be at the same context as the originating socket/flow. This eliminates the SELinux policy's ability to use/sendto SAs with contexts other than the socket's. With this patch applied, the SELinux policy will require one or more of the following for a socket to be able to communicate with/without SAs: 1. To enable a socket to communicate without using labeled-IPSec SAs: allow socket_t unlabeled_t:association { sendto recvfrom } 2. To enable a socket to communicate with labeled-IPSec SAs: allow socket_t self:association { sendto }; allow socket_t peer_sa_t:association { recvfrom }; Signed-off-by: Venkat Yekkirala <vyekkirala@TrustedCS.com> Signed-off-by: James Morris <jmorris@namei.org>

2006-12-02[PATCH] ieee80211: Drop and count duplicate data frames to remove 'replay ↵Larry Finger
detected' log messages In the SoftMAC version of the IEEE 802.11 stack, not all duplicate messages are detected. For the most part, there is no difficulty; however for TKIP and CCMP encryption, the duplicates result in a "replay detected" log message where the received and previous values of the TSC are identical. This change adds a new variable to the ieee80211_device structure that holds the 'seq_ctl' value for the previous frame. When a new frame repeats the value, the frame is dropped and the appropriate counter is incremented. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.
