2014-11-19bonding: change AD_LINK_SPEED_BITMASK to enum to suport more speedJianhua Xie1-32/+34
Port Key was determined as 16 bits according to the link speed, duplex and user key (which is yet not supported). In the old speed field, 5 bits are for speed [1|10|100|1000|10000]Mbps as below: -------------------------------------------------------------- Port key :| User key | Speed | Duplex| -------------------------------------------------------------- 16 6 1 0 This patch keeps the old layout, but changes AD_LINK_SPEED_BITMASK from bit type to an enum type. In this way, the speed field can expand speed type from 5 to 32. CC: Jay Vosburgh <j.vosburgh@gmail.com> CC: Veaceslav Falico <vfalico@gmail.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: David S.

2014-11-19separate kernel- and userland-side msghdrAl Viro5-23/+36
Kernel-side struct msghdr is (currently) using the same layout as userland one, but it's not a one-to-one copy - even without considering 32bit compat issues, we have msg_iov, msg_name and msg_control copied to kernel[1]. It's fairly localized, so we get away with a few functions where that knowledge is needed (and we could shrink that set even more). Pretty much everything deals with the kernel-side variant and the few places that want userland one just use a bunch of force-casts to paper over the differences. The thing is, kernel-side definition of struct msghdr is *not* exposed in include/uapi - libc doesn't see it, etc. So we can add struct user_msghdr, with proper annotations and let the few places that ever deal with those beasts use it for userland pointers. Saner typechecking aside, that will allow to change the layout of kernel-side msghdr - e.g. replace msg_iov/msg_iovlen there with struct iov_iter, getting rid of the need to modify the iovec as we copy data to/from it, etc. We could introduce kernel_msghdr instead, but that would create much more noise - the absolute majority of the instances would need to have the type switched to kernel_msghdr and definition of struct msghdr in include/linux/socket.h is not going to be seen by userland anyway. This commit just introduces user_msghdr and switches the few places that are dealing with userland-side msghdr to it. [1] actually, it's even trickier than that - we copy msg_control for sendmsg, but keep the userland address on recvmsg. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2014-11-19tcp: make connect() mem charging friendlyEric Dumazet1-40/+28
While working on sk_forward_alloc problems reported by Denys Fedoryshchenko, we found that tcp connect() (and fastopen) do not call sk_wmem_schedule() for SYN packet (and/or SYN/DATA packet), so sk_forward_alloc is negative while connect is in progress. We can fix this by calling regular sk_stream_alloc_skb() both for the SYN packet (in tcp_connect()) and the syn_data packet in tcp_send_syn_data() Then, tcp_send_syn_data() can avoid copying syn_data as we simply can manipulate syn_data->cb[] to remove SYN flag (and increment seq) Instead of open coding memcpy_fromiovecend(), simply use this helper. This leaves in socket write queue clean fast clone skbs. This was tested against our fastopen packetdrill tests.

If element is found it returns zero and stores element's value into value. If element is not found it returns -1 and sets errno to ENOENT. and further down in manpage: ENOENT For BPF_MAP_LOOKUP_ELEM or BPF_MAP_DELETE_ELEM, indicates that element with given key was not found. ----- In general all BPF commands return ENOENT when map element is not found (including BPF_MAP_GET_NEXT_KEY and BPF_MAP_UPDATE_ELEM with flags == BPF_MAP_UPDATE_ONLY) Subsequent patch adds a testsuite to check return values for all of these combinations.

2014-11-18bpf: add array type of eBPF mapsAlexei Starovoitov3-1/+153
add new map type BPF_MAP_TYPE_ARRAY and its implementation - optimized for fastest possible lookup() . in the future verifier/JIT may recognize lookup() with constant key and optimize it into constant pointer. Can optimize non-constant key into direct pointer arithmetic as well, since pointers and value_size are constant for the life of the eBPF program. In other words array_map_lookup_elem() may be 'inlined' by verifier/JIT while preserving concurrent access to this map from user space - two main use cases for array type: . 'global' eBPF variables: array of 1 element with key=0 and value is a collection of 'global' variables which programs can use to keep the state between events . aggregation of tracing events into fixed set of buckets - all array elements pre-allocated and zero initialized at init time - key as an index in array and can only be 4 byte - map_delete_elem() returns EINVAL, since elements cannot be deleted - map_update_elem() replaces elements in an non-atomic way (for atomic updates hashtable type should be used instead) Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

Both userspace and eBPF programs can lookup/update/delete elements from the map - eBPF programs can be called in_irq(), so use spin_lock_irqsave() mechanism for concurrent updates - key/value are opaque range of bytes (aligned to 8 bytes) - user space provides 3 configuration attributes via BPF syscall: key_size, value_size, max_entries - map takes care of allocating/freeing key/value pairs - map_update_elem() must fail to insert new element when max_entries limit is reached to make sure that eBPF programs cannot exhaust memory - map_update_elem() replaces elements in an atomic way - optimized for speed of lookup() which can be called multiple times from eBPF program which itself is triggered by high volume of events . in the future JIT compiler may recognize lookup() call and optimize it further, since key_size is constant for life of eBPF program Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.

2014-11-18bpf: add 'flags' attribute to BPF_MAP_UPDATE_ELEM commandAlexei Starovoitov3-4/+10
the current meaning of BPF_MAP_UPDATE_ELEM syscall command is: either update existing map element or create a new one. Initially the plan was to add a new command to handle the case of 'create new element if it didn't exist', but 'flags' style looks cleaner and overall diff is much smaller (more code reused), so add 'flags' attribute to BPF_MAP_UPDATE_ELEM command with the following meaning: #define BPF_ANY 0 /* create new element or update existing */ #define BPF_NOEXIST 1 /* create new element if it didn't exist */ #define BPF_EXIST 2 /* update existing element */ bpf_update_elem(fd, key, value, BPF_NOEXIST) call can fail with EEXIST if element already exists. bpf_update_elem(fd, key, value, BPF_EXIST) can fail with ENOENT if element doesn't exist. Userspace will call it as: int bpf_update_elem(int fd, void *key, void *value, __u64 flags) { union bpf_attr attr = { .map_fd = fd, .key = ptr_to_u64(key), .value = ptr_to_u64(value), .flags = flags; }; return bpf(BPF_MAP_UPDATE_ELEM, &attr, sizeof(attr)); } First two bits of 'flags' are used to encode style of bpf_update_elem() command.

2014-11-18i40e: Set XPS bit mask to zero in DCB modeNeerav Parikh1-7/+31
Due to DCBX configuration change if the VSI needs to use more than 1 TC; it needs to disable the XPS maps that were set when operating in 1 TC mode. Without disabling XPS the netdev layer will select queues based on those settings and not use the TC queue mapping to make the queue selection. This patch allows the driver to enable/disable the XPS based on the number of TCs being enabled for the given VSI.

2014-11-18i40e: Modify Tx disable wait flow in case of DCB reconfigurationNeerav Parikh2-0/+61
When DCB TC configuration changes the firmware suspends the port's Tx. Now, as DCB TCs may have changed the PF driver tries to reconfigure the TC configuration of the VSIs it manages. As part of this process it disables the VSI queues but the Tx queue disable will not complete as the port's Tx has been suspended. So, waiting for Tx queues to go to disable state in this flow may lead to detection of Tx queue disable timeout errors. Hence, this patch adds a new PF state so that if a port's Tx is in suspended state the Tx queue disable flow would just put the request for the queue to be disabled and return without waiting for the queue to be actually disabled. Once the VSI(s) TC reconfiguration has been done and driver has called firmware AQC "Resume PF Traffic" the driver checks the Tx queues requested to be disabled are actually disabled before re-enabling them again.

2014-11-18i40e: Update VEB's enabled_tc after reconfigurationNeerav Parikh1-0/+1
When the port TC configuration changes as a result of DCBx the driver modifies the enabled TCs for the VEBs it manages. But, in the process it did not update the enabled_tc value that it caches on a per VEB basis. So, when the next reconfiguration event occurs where the number of TC value is same as the value cached in enabled_tc for a given VEB; driver does not modify it's TC configuration by calling appropriate AQ command believing it is running with the same configuration as requested. Now, as the VEB is not actually enabled for the TCs that are there any TC configuration command for VSI attached to that VEB with TCs that are not enabled for the VEB fails. This patch fixes this issue.
