Nicolas Dichtel says: ==================== netlink: align attributes when needed (patchset #3) This is the continuation (series #3) of the work done to align netlink attributes when these attributes contain some 64-bit fields. It's the last patchset from what I've seen. The last user of nla_put_u64() is block/drbd. This module does not use standard netlink API (see all the stuff in include/linux/genl_magic_struct.h and include/linux/genl_magic_func.h). I didn't modify it because it's seems hard to do it whithout testing and fully understanding the context (for example, why include/linux/drbd_genl.h is not part of uapi?). Any thoughts? ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

I also fix the value of INET_DIAG_MAX. It's wrong since commit 8f840e47 which is only in net-next right now, thus I didn't make a separate patch. Fixes: 8f840e47 ("sctp: add the sctp_diag.c file") Signed-off-by:

Tom Herbert says: ==================== ila: Support for checksum neutral translations This patch set updates ILA to support draft-herbert-nvo3-ila-02. The primary addition is support checksum neutral ILA translation. This allows address to be performed and still keep any transport layer checksums that include the addresses in their pseudo header to still be correct without the translator needing to parse L4. Other items are: - Structures for ILA addresses, identifiers, locators - Disallow translation on non-ILA addresses (check by type in identifier). - Change xlat (nf_input) to translates solely based on matching locators not identifiers (since identifiers are not obfuscated by checksum neutral). - Side effect if above is that multiple ILA domains are supported. Each local locator can map to a different SIR address (ILA domain), and each domain defines its own identifier space. Tested: Ran TCP_RR with 200 cnxs. ILA performance is slightly better than previously since we are not longer parsing L4 for checksum handling. I amd seeing about 1% performance overhead. Also ran TCP_STREAM and tested non-ILA address (type=0) are not translated. v2: Fix compilation errors ==================== Signed-off-by: -

Support checksum neutral ILA as described in the ILA draft. The low order 16 bits of the identifier are used to contain the checksum adjustment value. The csum-mode parameter is added to described checksum processing. There are three values: - adjust transport checksum (previous behavior) - do checksum neutral mapping - do nothing On output the csum-mode in the ila_params is checked and acted on. If mode is checksum neutral mapping then to mapping and set C-bit. On input, C-bit is checked. If it is set checksum-netural mapping is done (regardless of csum-mode in ila params) and C-bit will be cleared. If it is not set then action in csum-mode is taken. Signed-off-by:

Change model of xlat to be used only for input where lookup is done on the locator part of an address (comparing to locator_match as key in rhashtable). This is needed for checksum neutral translation which obfuscates the low order 16 bits of the identifier. It also permits hosts to be in muliple ILA domains (each locator can map to a different SIR address). A check is also added to disallow translating non-ILA addresses (check of type in identifier).

Add structures for identifiers, locators, and an ila address which is composed of a locator and identifier and in6_addr can be cast to it. This includes a three bit type field and enums for the types defined in ILA I-D. In ILA lwt don't allow user to set a translation for a non-ILA address (type of identifier is zero meaning it is an IID). This also requires that the destination prefix is at least 65 bytes (64 bit locator and first byte of identifier). Signed-off-by:

This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6 PHYs of service DSAF are taken as ethernet ports to the CPU. The port-idx-in-ae can be 0 to 5. Here is the diagram: +-----+---------------+ | CPU | +-+-+-+---+-+-+-+-+-+-+ | | | | | | | | debug debug service port port port (0) (0) (0-5) In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical ports connect to a LAN Switch while the CPU side assume itself have one single NIC connect to this switch. In this case, the port-idx-in-ae will be 0 only. +-----+-----+------+------+ | CPU | +-+-+-+-+-+-+-+-+-+-+-+-+-+ | | service| port(0) debug debug +------------+ port port | switch | (0) (0) +-+-+-+-+-+-++ | | | | | | external port when port-idx-in-ae is not exists, old attribute port-id will be used (only for compatible purpose, not recommended to use port-id in new code).

Sowmini Varadhan says: ==================== pskb_extract() helper function. This patchset follows up on the discussion in https://www.mail-archive.com/netdev@vger.kernel.org/msg105090.html For RDS-TCP, we have to deal with the full gamut of nonlinear sk_buffs, including all the frag_list variants. Also, the parent skb has to remain unchanged, while the clone is queued for Rx on the PF_RDS socket. Patch 1 of this patchset adds a pskb_extract() function that does all this without the redundant memcpy's in pskb_expand_head() and __pskb_pull_tail(). v2: Marcelo Leitner review comments ==================== Signed-off-by:

rds-stress experiments with request size 256 bytes, 8K acks, using 16 threads show a 40% improvment when pskb_extract() replaces the {skb_clone(..); pskb_pull(..); pskb_trim(..);} pattern in the Rx path, so we leverage the perf gain with this commit.

Sowmini Varadhan authored
A pattern of skb usage seen in modules such as RDS-TCP is to extract `to_copy' bytes from the received TCP segment, starting at some offset `off' into a new skb `clone'. This is done in the ->data_ready callback, where the clone skb is queued up for rx on the PF_RDS socket, while the parent TCP segment is returned unchanged back to the TCP engine. The existing code uses the sequence clone = skb_clone(..); pskb_pull(clone, off, ..); pskb_trim(clone, to_copy, ..); with the intention of discarding the first `off' bytes. However, skb_clone() + pskb_pull() implies pksb_expand_head(), which ends up doing a redundant memcpy of bytes that will then get discarded in __pskb_pull_tail(). To avoid this inefficiency, this commit adds pskb_extract() that creates the clone, and memcpy's only the relevant header/frag/frag_list to the start of `clone'. pskb_trim() is then invoked to trim clone down to the requested to_copy bytes.

This works on the same implementation principle as codel*.h, i.e. there's a generic header with structures and macros and a implementation header carrying function definitions to include in given, e.g. driver or module. The fairness logic comes from net/sched/sch_fq_codel.c but is generalized so it is more flexible and easier to re-use. Signed-off-by:

Michal Kazior says: ==================== codel: make it reuseable beyond qdiscs There's an ongoing effort in fixing wireless bufferbloat. As part of that fq_codel is being ported into mac80211. To prevent code duplication codel.h needs to be slightly modified before it can be used in mac80211 (or other drivers FWIW).

It was impossible to include codel.h for the purpose of having access to codel_params or codel_vars structure definitions and using them for embedding in other more complex structures. This splits allows codel.h itself to be treated like any other header file while codel_qdisc.h and codel_impl.h contain function definitions with logic that was previously in codel.h. This copies over copyrights and doesn't involve code changes other than adding a few additional include directives to net/sched/sch*codel.c. Signed-off-by:

This strips out qdisc specific bits from the code and makes it slightly more reusable. Codel will be used by wireless/mac80211 in the future. Signed-off-by:

Commit 751a587a ("route: fix breakage after moving lwtunnel state") moved lwtstate to the end of dst_entry for 32bit archs. This makes it share the cacheline with __refcnt which had an unkown effect on performance. For this reason, the pointer was kept in place for 64bit archs. However, later performance measurements showed this is of no concern. It turns out that every performance sensitive path that accesses lwtstate accesses also struct rtable or struct rt6_info which share the same cache line. Thus, to get rid of a few #ifdefs, move the field to the end of the struct also for 64bit. Signed-off-by:

There's some inconsistency in current logic determining whether the link settings of a given interface can be changed; I.e., in all modes other than the so-called `deault' mode the interfaces are forbidden from changing the configuration - but even this rule is not applied to all user APIs that may change the configuration. Instead, let the core-module [qed] decide whether an interface can change the configuration by supporting a new API function. We also revise the current rule, allowing all interfaces to change their configurations while laying the infrastructure for future modes where an interface would be blocked from making such a configuration.
