2014-05-23net: filter: improve test case frameworkDaniel Borkmann1-155/+233
This patch simplifies and refactors the test case code a bit and also adds a summary of all test that passed or failed in the kernel log, so that it's easier to spot if something has failed. Future work could further extend the test framework to also support different input 'stimuli' i.e. related structures to seccomp.

2014-05-23net: filter: let unattached filters use sock_fprog_kernDaniel Borkmann9-17/+18
The sk_unattached_filter_create() API is used by BPF filters that are not directly attached or related to sockets, and are used in team, ptp, xt_bpf, cls_bpf, etc. As such all users do their own internal managment of obtaining filter blocks and thus already have them in kernel memory and set up before calling into sk_unattached_filter_create(). As a result, due to __user annotation in sock_fprog, sparse triggers false positives (incorrect type in assignment [different address space]) when filters are set up before passing them to sk_unattached_filter_create(). Therefore, let sk_unattached_filter_create() API use sock_fprog_kern to overcome this issue.

2014-05-23net: filter: remove DL macroDaniel Borkmann2-97/+99
Lets get rid of this macro. After commit 5bcfedf06f7f ("net: filter: simplify label names from jump-table"), labels have become more readable due to omission of BPF_ prefix but at the same time more generic, so that things like `git grep -n` would not find them. As a middle path, lets get rid of the DL macro as it's not strictly needed and would otherwise just hide the full name.

2014-05-23net: Make enabling of zero UDP6 csums more restrictiveTom Herbert4-6/+48
RFC 6935 permits zero checksums to be used in IPv6 however this is recommended only for certain tunnel protocols, it does not make checksums completely optional like they are in IPv4. This patch restricts the use of IPv6 zero checksums that was previously intoduced. no_check6_tx and no_check6_rx have been added to control the use of checksums in UDP6 RX and TX path. The normal sk_no_check_{rx,tx} settings are not used (this avoids ambiguity when dealing with a dual stack socket). A helper function has been added (udp_set_no_check6) which can be called by tunnel impelmentations to all zero checksums (send on the socket, and accept them as valid).

2014-05-23net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate through ip tool.Sucheta Chakraborty20-67/+156
o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: David S.

2014-05-22openvswitch: Reduce locking requirements.Jarno Rajahalme1-25/+29
Reduce and clarify locking requirements for ovs_flow_cmd_alloc_info(), ovs_flow_cmd_fill_info() and ovs_flow_cmd_build_info(). A datapath pointer is available only when holding a lock. Change ovs_flow_cmd_fill_info() and ovs_flow_cmd_build_info() to take a dp_ifindex directly, rather than a datapath pointer that is then (only) used to get the dp_ifindex. This is useful, since the dp_ifindex is available even when the datapath pointer is not, both before and after taking a lock, which makes further critical section reduction possible. Make ovs_flow_cmd_alloc_info() take an 'acts' argument instead a 'flow' pointer. This allows some future patches to do the allocation before acquiring the flow pointer. The locking requirements after this patch are: ovs_flow_cmd_alloc_info(): May be called without locking, must not be called while holding the RCU read lock (due to memory allocation). If 'acts' belong to a flow in the flow table, however, then the caller must hold ovs_mutex. ovs_flow_cmd_fill_info(): Either ovs_mutex or RCU read lock must be held. ovs_flow_cmd_build_info(): This calls both of the above, so the caller must hold ovs_mutex.

2014-05-22openvswitch: Avoid assigning a NULL pointer to flow actions.Jarno Rajahalme2-7/+11
Flow SET can accept an empty set of actions, with the intended semantics of leaving existing actions unmodified. This seems to have been brokin after OVS 1.7, as we have assigned the flow's actions pointer to NULL in this case, but we never check for the NULL pointer later on.

2014-05-22openvswitch: Compact sw_flow_key.Jarno Rajahalme3-123/+62
Minimize padding in sw_flow_key and move 'tp' top the main struct. These changes simplify code when accessing the transport port numbers and the tcp flags, and makes the sw_flow_key 8 bytes smaller on 64-bit systems (128->120 bytes). These changes also make the keys for IPv4 packets to fit in one cache line. There is a valid concern for safety of packing the struct ovs_key_ipv4_tunnel, as it would be possible to take the address of the tun_id member as a __be64 * which could result in unaligned access in some systems. However: - sw_flow_key itself is 64-bit aligned, so the tun_id within is always 64-bit aligned. - We never make arrays of ovs_key_ipv4_tunnel (which would force every second tun_key to be misaligned). - We never take the address of the tun_id in to a __be64 *. - Whereever we use struct ovs_key_ipv4_tunnel outside the sw_flow_key, it is in stack (on tunnel input functions), where compiler has full control of the alignment.

2014-05-22ieee802154: missing put_dev() on errorDan Carpenter1-2/+4
We should call put_dev() on the error path here. Fixes: 3e9c156e2c21 ('ieee802154: add netlink interfaces for llsec') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-22net: cdc_ncm: fix typo in test for supported formatsDan Carpenter1-1/+2
There is a typo here where we test for USB_CDC_NCM_NTH32_SIGN instead of USB_CDC_NCM_NTB32_SUPPORTED. The test probably still works as written because 0x686D636E has (1 << 1) set and doesn't have (1 << 0) set.
