Roman Mashak says: ==================== net sched actions: code style cleanup and fixes The patchset fixes a few code stylistic issues and typos, as well as one detected by sparse semantic checker tool. No functional changes introduced. Patch 1 & 2 fix coding style bits caught by the checkpatch.pl script Patch 3 fixes an issue with a shadowed variable Patch 4 adds sizeof() operator instead of magic number for buffer length Patch 5 fixes typos in diagnostics messages Patch 6 explicitly sets unsigned char for bitwise operation v2: - submit for net-next - added Reviewed-by tags - use u8* instead of char* as per Davide Caratti suggestion ==================== Signed-off-by: NDavid S.

Extend slotting with support for non-uniform distributions. This is similar to netem's non-uniform distribution delay feature. Commit f043efeae2f1 ("netem: support delivering packets in delayed time slots") added the slotting feature to approximate the behaviors of media with packet aggregation but only supported a uniform distribution for delays between transmission attempts. Tests with TCP BBR with emulated wifi links with non-uniform distributions produced more useful results. Syntax: slot dist DISTRIBUTION DELAY JITTER [packets MAX_PACKETS] \ [bytes MAX_BYTES] The syntax and use of the distribution table is the same as in the non-uniform distribution delay feature. A file DISTRIBUTION must be present in TC_LIB_DIR (e.g. /usr/lib/tc) containing numbers scaled by NETEM_DIST_SCALE. A random value x is selected from the table and it takes DELAY + ( x * JITTER ) as delay. Correlation between values is not supported. Examples: Normal distribution delay with mean = 800us and stdev = 100us. > tc qdisc add dev eth0 root netem slot dist normal 800us 100us Optionally set the max slot size in bytes and/or packets. > tc qdisc add dev eth0 root netem slot dist normal 800us 100us \ bytes 64k packets 42 Signed-off-by: NYousuk Seung <ysseung@google.com> Acked-by: NEric Dumazet <edumazet@google.com> Acked-by: NNeal Cardwell <ncardwell@google.com> Signed-off-by: NDavid S.

'sockaddr_len' is checked against various values when entering pppol2tp_connect(), to verify its validity. It is used again later, to find out which sockaddr structure was passed from user space. This patch combines these two operations into one new function in order to simplify pppol2tp_connect(). A new structure, l2tp_connect_info, is used to pass sockaddr data back to pppol2tp_connect(), to avoid passing too many parameters to l2tp_sockaddr_get_info(). Also, the first parameter is void* in order to avoid casting between all sockaddr_* structures manually. Signed-off-by: NGuillaume Nault <g.nault@alphalink.fr> Signed-off-by: NDavid S.

In patch #3, the function tc_rule_stats_get() is parameterized to be useful for egress rules as well. In patch #4, a new function __simple_if_init() is extracted from simple_if_init(). This covers the logic that needs to be done for the usual interface: VRF migration, upping and installation of IP addresses. Patch #5 then adds the test itself.

The latter comes in handy when adding more interfaces into a VRF later on. The situation is similar for simple_if_fini().

Jakub Kicinski says: ==================== net: sched: support replay of filter offload when binding to block This series from John adds the ability to replay filter offload requests when new offload callback is being registered on a TC block. This is most likely to take place for shared blocks today, when a block which already has rules is bound to another interface. Prior to this patch set if any of the rules were offloaded the block bind would fail. A new tcf_proto_op is added to generate a filter-specific offload request. The new 'offload' op is supporting extack from day 0, hence we need to propagate extack to .ndo_setup_tc TC_BLOCK_BIND/TC_BLOCK_UNBIND and through tcf_block_cb_register() to tcf_block_playback_offloads(). The immediate use of this patch set is to simplify life of drivers which require duplicating rules when sharing blocks. Switch drivers (mlxsw) can bind ports to rule lists dynamically, NIC drivers generally don't have that ability and need the rules to be duplicated for each ingress they match on. In code terms this means that switch drivers don't register multiple callbacks for each port. NIC drivers do, and get a separate request and hance rule per-port, as if the block was not shared. The registration fails today, however, if some rules were already present. As John notes in description of patch 7, drivers which register multiple callbacks to shared blocks will likely need to flush the rules on block unbind. This set makes the core not only replay the the offload add requests but also offload remove requests when callback is unregistered. v2: - name parameters in patch 2; - use unsigned int instead of u32 for in_hw_coun; - improve extack message in patch 7. ==================== Signed-off-by: NDavid S.

Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a block when a callback tries to register to a block that already has offloaded rules. If all existing rules cannot be offloaded then the registration is rejected. This replaces the previous policy of rejecting such callback registration outright. On unregistration of a callback, the rules are flushed for that given cb. The implementation of block sharing in the NFP driver, for example, duplicates shared rules to all devs bound to a block. This meant that rules could still exist in hw even after a device is unbound from a block (assuming the block still remains active).

Add the offload tcf_proto_op in cls_bpf to generate an offload message for each bpf prog in the given tcf_proto. Call the specified callback with this new offload message. The function only returns an error if the callback rejects adding a 'hardware only' prog. A prog contains a flag to indicate if it is in hardware or not. To ensure the offload function properly maintains this flag, keep a reference counter for the number of instances of the prog that are in hardware. Only update the flag when this counter changes from or to 0.
