Since rules are being written to or deleted from the Bloom filter on such transitions, it is not required to keep the same eRP bank ID for the master RP. Change master RP index assignment so it will be assigned with zero. This is consistent with the assignment of the first available spot that is used for allocating eRP's indices.

When the region has only a single rule pattern then eRP table is not used, however insertion of another pattern would trigger a move to an active eRP table so it is imperative to update the Bloom filter with all previously configured rules. Add a method that updates Bloom filter entries for all rules currently configured in the region, on the event of a transition from master mask to eRP, or vice versa. For that purpose, maintain a list of all A-TCAM rules within mlxsw_sp_acl_atcam_region.

Miller <davem@davemloft.net> 2018-12-16mlxsw: spectrum_acl: Add Bloom filter handlingNir Dotan2-0/+219 Spectrum-2 HW uses Bloom filter in order to skip lookups on specific eRPs. It uses crc-16-Msbit-first calculation over a specific layout of a rule's key fields combined with eRP ID as well as region ID. Per potential lookup, iff the Bloom filter entry of the calculated index is empty, then the lookup can be skipped. Hence, the mlxsw driver should update the Bloom filter entry per each rule insertion or deletion when rules are part of an eRP. Add functions for adding and deleting entries in the Bloom filter. In order to do so also add crc-16 computation based on the specific Spectrum-2 polynomial and a function for encoding the crc-16 input in the manner dictated by HW implementation.

This caused segfaults in DCCP lookups because DCCP did not initialize the (addr,port) hashtable. This patch adds said initialization. The only non-trivial issue here is the size of the new hashtable. It seemed reasonable to make it match the size of the port-only hashtable (= INET_LHTABLE_SIZE) that was used previously. Other parameters to inet_hashinfo2_init() match those used in TCP. Tested: syzcaller issues fixed; the second patch in the patchset tests that DCCP lookups work correctly.

See section 6.5 in RFC 1661 for details. So let's decompress protocol field if needed, the same way it's done in drivers/net/ppp/pptp.c. In case when "nopcomp" pppd option is not enabled, PFC (pcomp) can be negotiated during LCP handshake, and L2TP driver in kernel will receive PPP packets with compressed Protocol field, which in turn leads to next error: Protocol Rejected (unsupported protocol 0x2145) because instead of Protocol=0x0021 in PPP packet there will be Protocol=0x21. This patch unwraps it back to 0x0021, which fixes the issue. Sending the compressed Protocol field will be implemented in subsequent patch, this one is self-sufficient.
