Follow upstream kernel patch that restores always splitting gso packets by default whilst making the option configurable from (tc) userspace. No ABI/API change Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
Bump to the latest cake recipe. This backports tc class support to kernel 4.9 and other than conditional kernel compilation pre-processor macros represents the cake that has gone upstream into kernel 4.19. Loud cheer! Fun may be had by changing cake tin classification for packets on ingress. e.g. tc filter add dev ifb4eth0 parent 800b: protocol ip u32 match \ ip dport 6981 0xffff action skbedit priority 800b:1 Where 800b: represents the filter handle for the ifb obtained by 'tc qdisc' and the 1 from 800b:1 represents the cake tin number. So the above example puts all incoming packets destined for port 6981 into the BULK (lowest priority) tin. f39ab9a Obey tin_order for tc filter classifiers 1e2473f Clean up after latest backport. 82531d0 Reorder includes to fix out of tree compilation 52cbc00 Code style cleanup 6cdb496 Fix argument order for NL_SET_ERR_MSG_ATTR() cab17b6 Remove duplicate call to qdisc_watchdog_init() 71c7991 Merge branch 'backport-classful' 32aa7fb Fix compilation on Linux 4.9 9f8fe7a Fix compilation on Linux 4.14 ceab7a3 Rework filter classification aad5436 Fixed version of class stats be1c549 Add cake-specific class stats 483399d Use tin_order for class dumps 80dc129 Add class dumping 0c8e6c1 Fix dropping when using filters c220493 Add the minimum class ops 5ed54d2 Start implementing tc filter/class support Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

This bumps to the latest & possibly greatest cake, sadly it's still inedible but from an SQM point of view quite tasty :-) Main tweaks since previous bump, improved ack_filter, some extra stats, support for 64bit netlink parameters (higher rates/byte counters) 0520a6c Fix NAT option handling 8da93e1 Make sure we always call qdisc_watchdog_init() in cake_init() f65daf6 Fix mismatched parenthesis 51d4ab3 Change flag handling to be safe even when mixing with non-eligible ACKs f2ea091 ack_filter: protect DCTCP with stricter filtering of ECE marks 28b4560 ACK filter: Handle wrapping sequence numbers and DSACKs 73f62d9 Use the right PAD attribute for options 5969c14 Use 32 for tin backlog e289f31 Move all the u64 netlink attributes together 36180a0 Check ACK seqno before parsing SACKs 91bbc01 Merge branch 'mine' into cobalt 58c55ec Rework SACK check to compare the ranges of two SACKs 9a5d593 ack_filter: Add proper handling of SACKs eca95d4 ack_filter: short-circuit TCP flag check d50a246 compat: backport some ktime functions 7b7ad11 compat: define tcpopt_fastopen for pre-4.1 kernels ca54cdb Fix ktime compare 9d7dcc0 ack filter: Parse TCP options and only drop safe ones b119882 Return EOPNOTSUPP on NAT option if conntrack is not available 842d7f0 Don't try to pad stats with tin_stats padding bd46dc2 Use 64-bit divide helper 8e41bf0 Make sure we never drop SACKs when filtering ACKs 66e5d60 Avoid comparing ktime_t to scalar values 7fab017 Actually commit the ktime_t changes fca6d13 Switch to ktime_t and get rid of cobalt.h 6f7e5af Can't use do_div with 64-bit divisors Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
Following changes as part of the kernel upstreaming attempts. And fix a slight fsck up when calculating overheads for GSO packets. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
No functional change. Code tidy ups. 735eaf2 Make sure we don't reallocate q->tins (we didn't anyway but his really makes sure) 6c5ad6e Get rid of __GFP_NOWARN flag for memory allocation 2a37333 Don't need the wrapper for kvfree, and no need to check before calling it 2b1c631 Whitespace fix 7fe6e28 compat tidyup (for older kernel versions <4.4) 93b805c pedant tidy up superfluous semicolons on switch statements Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software. Cake is bearing fruits of kernel upstreaming efforts. diffserv-llt dropped. DSCP mapping paper died and no one using it. ack-filter re-written & simplified tc userspace & cake kmod netlink interface usage changed in non backwards compatible way, thus this once requires tc & cake to be in-step. Change due to upstream requirements. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
