2018-12-17nfp: flower: fix cb_ident duplicate in indirect block registerJohn Hurley1-10/+11
Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the netdev we were interested in receiving updates on. This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

2018-12-17net: dccp: initialize (addr,port) listening hashtablePeter Oskolkov2-0/+4
Commit d9fbc7f6431f "net: tcp: prefer listeners bound to an address" removes port-only listener lookups. 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. V2 changes: marked inet_hashinfo2_init as an exported symbol so that DCCP compiles when configured as a module. Tested: syzcaller issues fixed; the second patch in the patchset tests that DCCP lookups work correctly.

2018-12-17bnxt_en: Disable MSIX before re-reserving NQs/CMPL rings.Michael Chan1-8/+11
When bringing up a device, the code checks to see if the number of MSIX has changed. pci_disable_msix() should be called first before changing the number of reserved NQs/CMPL rings. This ensures that the MSIX vectors associated with the NQs/CMPL rings are still properly mapped when pci_disable_msix() masks the vectors. This patch will prevent errors when RDMA support is added for the new 57500 chips. When the RDMA driver shuts down, the number of NQs is decreased and we must use the new sequence to prevent MSIX errors.

Also add a new parameter resv_stat_ctxs to better keep track of stat_ctxs reserved including resources used by RDMA. Add a stat_ctxs parameter to all the relevant resource reservation functions so we can reserve the correct number of stat_ctxs.

2018-12-17fou: Prevent unbounded recursion in GUE error handlerStefano Brivio1-0/+7
Handling exceptions for direct UDP encapsulation in GUE (that is, UDP-in-UDP) leads to unbounded recursion in the GUE exception handler, syzbot reported. While draft-ietf-intarea-gue-06 doesn't explicitly forbid direct encapsulation of UDP in GUE, it probably doesn't make sense to set up GUE this way, and it's currently not even possible to configure this. Skip exception handling if the GUE proto/ctype field is set to the UDP protocol number. Should we need to handle exceptions for UDP-in-GUE one day, we might need to either explicitly set a bound for recursion, or implement a special iterative handling for these cases.

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.
