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:

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:

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. Signed-off-by:

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.

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:

nfmark is being used in various subsystems and has become the defacto mark field for all kinds of packets. Therefore it makes sense to rename it to `mark' and remove the dependency on CONFIG_NETFILTER. Signed-off-by:

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:

Since the upstreaming of the mlsxfrm modification a few months back, testing has resulted in the identification of the following issues/bugs that are resolved in this patch set. 1. Fix the security context used in the IKE negotiation to be the context of the socket as opposed to the context of the SPD rule. 2. Fix SO_PEERSEC for tcp sockets to return the security context of the peer as opposed to the source. 3. Fix the selection of an SA for an outgoing packet to be at the same context as the originating socket/flow. The following would be the result of applying this patchset: - SO_PEERSEC will now correctly return the peer's context. - IKE deamons will receive the context of the source socket/flow as opposed to the SPD rule's context so that the negotiated SA will be at the same context as the source socket/flow. - 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 }; This Patch: Pass correct security context to IKE for use in negotiation Fix the security context passed to IKE for use in negotiation to be the context of the socket as opposed to the context of the SPD rule so that the SA carries the label of the originating socket/flow.
