Also changes: ret = nf_nat_ipv4_fn(priv, skb, state); if (ret != NF_DROP && ret != NF_STOLEN && into if (ret != NF_ACCEPT) return ret; everywhere. The nat hooks never should return anything other than ACCEPT or DROP (and the latter only in rare error cases). The original code uses multi-line ANDing including assignment-in-if: if (ret != NF_DROP && ret != NF_STOLEN && !(IPCB(skb)->flags & IPSKB_XFRM_TRANSFORMED) && (ct = nf_ct_get(skb, &ctinfo)) != NULL) { I removed this while moving, breaking those in separate conditionals and moving the assignments into extra lines. checkpatch still generates some warnings: 1. Overly long lines (of moved code). Breaking them is even more ugly. so I kept this as-is. 2. use of extern function declarations in a .c file. This is necessary evil, we must call nf_nat_l3proto_register() from the nat core now. All l3proto related functions are removed later in this series, those prototypes are then removed as well. v2: keep empty nf_nat_ipv6_csum_update stub for CONFIG_IPV6=n case. v3: remove IS_ENABLED(NF_NAT_IPV4/6) tests, NF_NAT_IPVx toggles are removed here. v4: also get rid of the assignments in conditionals.

None of these functions calls any external functions, moving them allows to avoid both the indirection and a need to export these symbols. Signed-off-by:

The Amanda CONNECT command has been updated to establish an optional fourth connection [0]. Previously, a CONNECT command would look like: CONNECT DATA port0 MESG port1 INDEX port2 nf_conntrack_amanda analyses the CONNECT command string in order to learn the port numbers of the related DATA, MESG and INDEX streams. As of amanda v3.4, the CONNECT command can advertise an additional port: CONNECT DATA port0 MESG port1 INDEX port2 STATE port3 The new STATE stream is not handled, thus the connection on the STATE port cannot be established. The patch adds support for STATE streams to the amanda conntrack helper. I tested with max_expected = 3, leaving the other patch hunks unmodified. Amanda reports "connection refused" and aborts. After I set max_expected to 4, the backup completes successfully.

Add .release_ops, that is called in case of error at a later stage in the expression initialization path, ie. .select_ops() has been already set up operations and that needs to be undone. This allows us to unwind .select_ops from the error path, ie. release the dynamic operations for this extension. Moreover, allocate one single operation instead of recycling them, this comes at the cost of consuming a bit more memory per rule, but it simplifies the infrastructure. Signed-off-by: -

Roopa Prabhu says: ==================== vxlan: create and changelink extack support This series adds extack support to changelink paths. In the process re-factors flag sets to a separate helper. Also adds some changelink testcases to rtnetlink.sh (This series was initially part of another series that tried to support changelink for more attributes. But after some feedback from sabrina, i have dropped the 'support changelink for more attributes' part because some of them cannot be supported today or may require additional use-case handling code. These can be done separately as and when we see the need for it.) ==================== Signed-off-by: -

Jakub Kicinski says: ==================== devlink: make ethtool compat reliable This is a follow up to the series which added device flash updates via devlink. I went with the approach of adding a new NDO in the end. It seems to end up looking cleaner. First patch removes the option to build devlink as a module. Users can still decide to not build it, but the module option ends up not being worth the maintenance cost. Next two patches add a NDO which can be used to ask the driver to return a devlink instance associated with a given netdev, instead of iterating over devlink ports. Drivers which implement this NDO must take into account the potential impact on the visibility of the devlink instance. With the new NDO in place we can remove NFP ethtool flash update code. Fifth patch makes sure we hold a reference to dev while callbacks are active. Last but not least the NULL-check of devlink->ops is moved to instance allocation time. Last but not least missing checks for devlink->ops are added. There is currently no driver registering devlink without ops, so can just fix this in -next. v2 (Michal): add netdev_to_devlink() in patch 3. v3 (Florian): - add missing checks for devlink->ops; - move locking/holding into devlink_compat_ functions. v4 (Jiri): - hold devlink_mutex around callbacks (patch 2); - require non-NULL ops (patch 6). ==================== Signed-off-by: -
Jakub Kicinski authored
Commit 76726ccb ("devlink: add flash update command") and commit 2d8dc5bb ("devlink: Add support for reload") access devlink ops without NULL-checking. There is, however, no driver which would pass in NULL ops, so let's just make that a requirement. Remove the now unnecessary NULL-checking. Signed-off-by:

Being able to build devlink as a module causes growing pains. First all drivers had to add a meta dependency to make sure they are not built in when devlink is built as a module. Now we are struggling to invoke ethtool compat code reliably. Make devlink code built-in, users can still not build it at all but the dynamically loadable module option is removed. Signed-off-by:

Leslie Monis says: ==================== net: sched: pie: align PIE implementation with RFC 8033 The current implementation of the PIE queuing discipline is according to the IETF draft [http://tools.ietf.org/html/draft-pan-aqm-pie-00] and the paper [PIE: A Lightweight Control Scheme to Address the Bufferbloat Problem]. However, a lot of necessary modifications and enhancements have been proposed in RFC 8033, which have not yet been incorporated in the source code of Linux. This patch series helps in achieving the same. Performance tests carried out using Flent [https://flent.org/] Changes from v2 to v3: - Used div_u64() instead of direct division after explicit type casting as recommended by David Changes from v1 to v2: - Excluded the patch setting PIE dynamically active/inactive as the test results were unsatisfactory - Fixed a scaling issue when adding more auto-tuning cases which caused local variables to underflow - Changed the long if/else chain to a loop as suggested by Stephen - Changed the position of the accu_prob variable in the pie_vars structure as recommended by Stephen ==================== Acked-by:
