2020-03-15nft_set_pipapo: Prepare for single ranged field usageStefano Brivio
A few adjustments in nft_pipapo_init() are needed to allow usage of this set back-end for a single, ranged field. Provide a convenient NFT_PIPAPO_MIN_FIELDS definition that currently makes sure that the rbtree back-end is selected instead, for sets with a single field. This finally allows a fair comparison with rbtree sets, by defining NFT_PIPAPO_MIN_FIELDS as 0 and skipping rbtree back-end initialisation: ---------------.--------------------------.-------------------------.

2020-03-15nft_set_pipapo: Introduce AVX2-based lookup implementationStefano Brivio
If the AVX2 set is available, we can exploit the repetitive characteristic of this algorithm to provide a fast, vectorised version by using 256-bit wide AVX2 operations for bucket loads and bitwise intersections. In most cases, this implementation consistently outperforms rbtree set instances despite the fact they are configured to use a given, single, ranged data type out of the ones used for performance measurements by the nft_concat_range.sh kselftest. That script, injecting packets directly on the ingoing device path with pktgen, reports, averaged over five runs on a single AMD Epyc 7402 thread (3.35GHz, 768 KiB L1D$, 12 MiB L2$), the figures below. CONFIG_RETPOLINE was not set here. Note that this is not a fair comparison over hash and rbtree set types: non-ranged entries (used to have a reference for hash types) would be matched faster than this, and matching on a single field only (which is the case for rbtree) is also significantly faster. However, it's not possible at the moment to choose this set type for non-ranged entries, and the current implementation also needs a few minor adjustments in order to match on less than two fields. ---------------.-----------------------------------.------------.

2020-03-15nft_set_pipapo: Prepare for vectorised implementation: alignmentStefano Brivio
SIMD vector extension sets require stricter alignment than native instruction sets to operate efficiently (AVX, NEON) or for some instructions to work at all (AltiVec). Provide facilities to define arbitrary alignment for lookup tables and scratch maps. By defining byte alignment with NFT_PIPAPO_ALIGN, lt_aligned and scratch_aligned pointers become available. Additional headroom is allocated, and pointers to the possibly unaligned, originally allocated areas are kept so that they can be freed.

2020-03-15nft_set_pipapo: Add support for 8-bit lookup groups and dynamic switchStefano Brivio
While grouping matching bits in groups of four saves memory compared to the more natural choice of 8-bit words (lookup table size is one eighth), it comes at a performance cost, as the number of lookup comparisons is doubled, and those also needs bitshifts and masking. Introduce support for 8-bit lookup groups, together with a mapping mechanism to dynamically switch, based on defined per-table size thresholds and hysteresis, between 8-bit and 4-bit groups, as tables grow and shrink. Empty sets start with 8-bit groups, and per-field tables are converted to 4-bit groups if they get too big. An alternative approach would have been to swap per-set lookup operation functions as needed, but this doesn't allow for different group sizes in the same set, which looks desirable if some fields need significantly more matching data compared to others due to heavier impact of ranges (e.g. a big number of subnets with relatively simple port specifications). Allowing different group sizes for the same lookup functions implies the need for further conditional clauses, whose cost, however, appears to be negligible in tests. The matching rate figures below were obtained for x86_64 running the nft_concat_range.sh "performance" cases, averaged over five runs, on a single thread of an AMD Epyc 7402 CPU, and for aarch64 on a single thread of a BCM2711 (Raspberry Pi 4 Model B 4GB), clocked at a stable 2147MHz frequency: ---------------.-----------------------------------.------------.

2020-03-15nft_set_pipapo: Generalise group size for bucketsStefano Brivio
Get rid of all hardcoded assumptions that buckets in lookup tables correspond to four-bit groups, and replace them with appropriate calculations based on a variable group size, now stored in struct field. The group size could now be in principle any divisor of eight. Note, though, that lookup and get functions need an implementation intimately depending on the group size, and the only supported size there, currently, is four bits, which is also the initial and only used size at the moment.

2020-03-15netfilter: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] Lastly, fix checkpatch.pl warning WARNING: __aligned(size) is preferred over __attribute__((aligned(size))) in net/bridge/netfilter/ebtables.c This issue was found with the help of Coccinelle.

2020-03-15netfilter: xtables: Add snapshot of hardidletimer targetManoj Basapathi
This is a snapshot of hardidletimer netfilter target. This patch implements a hardidletimer Xtables target that can be used to identify when interfaces have been idle for a certain period of time. Timers are identified by labels and are created when a rule is set with a new label. The rules also take a timeout value (in seconds) as an option. If more than one rule uses the same timer label, the timer will be restarted whenever any of the rules get a hit. One entry for each timer is created in sysfs. This attribute contains the timer remaining for the timer to expire. The attributes are located under the xt_idletimer class: /sys/class/xt_idletimer/timers/<label> When the timer expires, the target module sends a sysfs notification to the userspace, which can then decide what to do (eg. disconnect to save power) Compared to IDLETIMER, HARDIDLETIMER can send notifications when CPU is in suspend too, to notify the timer expiry. v1->v2: Moved all functionality into IDLETIMER module to avoid code duplication per comment from Florian.

Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver already correctly rejected almost all unsupported parameters (missing sample_rate_interval). As a side effect of these changes the error code for unsupported params changes from EINVAL to EOPNOTSUPP. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

Antoine Tenart says: ==================== net: phy: split the mscc driver This is a proposal to split the MSCC PHY driver, as its code base grew a lot lately (it's already 3800+ lines). It also supports features requiring a lot of code (MACsec), which would gain in being split from the driver core, for readability and maintenance. This is also done as other features should be coming later, which will also need lots of code addition. This series shouldn't change the way the driver works. I checked, and there were no patch pending on this driver. This change was done on top of all the modifications done on this driver in net-next. Since v2: - Defined inline functions as static inline. - Fixed a locking issue reported by Kbuild. Since v1: - Moved more definitions into the mscc_macsec.h header. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
