2015-07-31bonding: add tlb_dynamic_lb netlink supportNikolay Aleksandrov1-2/+15
tlb_dynamic_lb could be set only via sysfs, this patch allows it to be set via netlink. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-06-23bonding: Display LACP info only to CAP_NET_ADMIN capable userMahesh Bandewar1-11/+12
Actor and Partner details can be accessed via proc-fs, sys-fs entries or netlink interface. These interfaces are world readable at this moment. The earlier patch-series made the LACP communication secure to avoid nuisance attack from within the same L2 domain but it did not prevent "someone unprivileged" looking at that information on host and perform the same act. This patch essentially avoids spitting those entries if the user in question does not have enough privileges.

Export the partner_oper_port_state of each port via sysfs and netlink. In 802.3ad mode it is valuable for the user to be able to check the partner_oper state, it is already exported via bond's proc entry.

This patch adds support for slave_changelink to the bonding and uses it to give the ability to change the queue_id of the enslaved devices via netlink. It sets slave_maxtype and uses bond_changelink as a prototype for bond_slave_changelink. Example/test command after the iproute2 patch: ip link set eth0 type bond_slave queue_id 10 CC: David S.

2014-01-21reciprocal_divide: update/correction of the algorithmHannes Frederic Sowa1-4/+0
Jakub Zawadzki noticed that some divisions by reciprocal_divide() were not correct [1][2], which he could also show with BPF code after divisions are transformed into reciprocal_value() for runtime invariance which can be passed to reciprocal_divide() later on; reverse in BPF dump ended up with a different, off-by-one K in some situations. This has been fixed by Eric Dumazet in commit aee636c4809fa5 ("bpf: do not use reciprocal divide"). This follow-up patch improves reciprocal_value() and reciprocal_divide() to work in all cases by using Granlund and Montgomery method, so that also future use is safe and without any non-obvious side-effects. Known problems with the old implementation were that division by 1 always returned 0 and some off-by-ones when the dividend and divisor where very large. This seemed to not be problematic with its current users, as far as we can tell. Eric Dumazet checked for the slab usage, we cannot surely say so in the case of flex_array. Still, in order to fix that, we propose an extension from the original implementation from commit 6a2d7a955d8d resp. [3][4], by using the algorithm proposed in "Division by Invariant Integers Using Multiplication" [5], Torbjörn Granlund and Peter L. Montgomery, that is, pseudocode for q = n/d where q, n, d is in u32 universe: 1) Initialization: int l = ceil(log_2 d) uword m' = floor((1<<32)*((1<<l)-d)/d)+1 int sh_1 = min(l,1) int sh_2 = max(l-1,0) 2) For q = n/d, all uword: uword t = (n*m')>>32 q = (t+((n-t)>>sh_1))>>sh_2 The assembler implementation from Agner Fog [6] also helped a lot while implementing. We have tested the implementation on x86_64, ppc64, i686, s390x; on x86_64/haswell we're still half the latency compared to normal divide. Joint work with Daniel Borkmann.
