Currently, writing into net.ipv6.conf.all.{accept_dad,use_optimistic,optimistic_dad} has no effect. Fix handling of these flags by: - using the maximum of global and per-interface values for the accept_dad flag. That is, if at least one of the two values is non-zero, enable DAD on the interface. If at least one value is set to 2, enable DAD and disable IPv6 operation on the interface if MAC-based link-local address was found - using the logical OR of global and per-interface values for the optimistic_dad flag. If at least one of them is set to one, optimistic duplicate address detection (RFC 4429) is enabled on the interface - using the logical OR of global and per-interface values for the use_optimistic flag. If at least one of them is set to one, optimistic addresses won't be marked as deprecated during source address selection on the interface. While at it, as we're modifying the prototype for ipv6_use_optimistic_addr(), drop inline, and let the compiler decide.

Commit f784ad3d ("ipv6: do not send RTM_DELADDR for tentative addresses") incorrectly assumes that no RTM_NEWADDR are sent for addresses in tentative state, as this does happen for the standard IPv6 use-case of DAD failure, see the call to ipv6_ifa_notify() in addconf_dad_stop(). So as a result of this change, no RTM_DELADDR is sent after DAD failure for a link-local when strict DAD (accept_dad=2) is configured, or on the next admin down in other cases. The absence of this notification breaks backwards compatibility and causes problems after DAD failure if this notification was being relied on. The solution is to allow RTM_DELADDR to still be sent after DAD failure. Fixes: f784ad3d ("ipv6: do not send RTM_DELADDR for tentative addresses") Signed-off-by:

Commit 109980b8 ("bpf: don't select potentially stale ri->map from buggy xdp progs") passed the pointer to the prog itself to be loaded into r4 prior on bpf_redirect_map() helper call, so that we can store the owner into ri->map_owner out of the helper. Issue with that is that the actual address of the prog is still subject to change when subsequent rewrites occur that require slow path in bpf_prog_realloc() to alloc more memory, e.g. from patching inlining helper functions or constant blinding. Thus, we really need to take prog->aux as the address we're holding, which also works with prog clones as they share the same aux object. Instead of then fetching aux->prog during runtime, which could potentially incur cache misses due to false sharing, we are going to just use aux for comparison on the map owner. This will also keep the patchlet of the same size, and later check in xdp_map_invalid() only accesses read-only aux pointer from the prog, it's also in the same cacheline already from prior access when calling bpf_func.

This patch is pretty much a carbon copy of commit 3079c652 ("caif: Fix napi poll list corruption") with "caif" replaced by "emac". The commit d75b1ade ("net: less interrupt masking in NAPI") breaks emac. It is now required that if the entire budget is consumed when poll returns, the napi poll_list must remain empty. However, like some other drivers emac tries to do a last-ditch check and if there is more work it will call napi_reschedule and then immediately process some of this new work. Should the entire budget be consumed while processing such new work then we will violate the new caller contract. This patch fixes this by not touching any work when we reschedule in emac.

Our recent change exposed a bug in TCP Fastopen Client that syzkaller found right away [1] When we prepare skb with SYN+DATA, we attempt to transmit it, and we update socket state as if the transmit was a success. In socket RTX queue we have two skbs, one with the SYN alone, and a second one containing the DATA. When (malicious) ACK comes in, we now complain that second one had no skb_mstamp. The proper fix is to make sure that if the transmit failed, we do not pretend we sent the DATA skb, and make it our send_head. When 3WHS completes, we can now send the DATA right away, without having to wait for a timeout.

There are several problems with commit 10377ba7 ("net: systemport: Support 64bit statistics", first one got fixed in 7095c973 ("net: systemport: Fix 64-bit stats deadlock"). The second problem is that this specific code updates the stats64.tx_{packets,bytes} from ndo_get_stats64() and that is what we are returning to ethtool -S. If we are not running a tool that involves calling ndo_get_stats64(), then we won't get updated ethtool stats. The solution to this is to update the stats from both call sites, factoring that into a specific function, While at it, don't just check the sizeof() but also the type of the statistics in order to use the 64-bit stats seqlock.

However, when $clsname is 'matchall', a systematic crash can be observed in htb_classify(). HTB and classful qdiscs don't assign initial value to struct tcf_result, but then they expect it to contain valid values after filters have been run. Thus, current 'matchall' ignores the TCA_MATCHALL_CLASSID attribute, configured by user, and makes HTB (and classful qdiscs) dereference random pointers. By assigning head->res to *res in mall_classify(), before the actions are invoked, we fix this crash and enable TCA_MATCHALL_CLASSID functionality, that had no effect on 'matchall' classifier since its first introduction.

Commit 5620a0d1 ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum. The default for EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/. Fixes: 5620a0d1 ("firmware: delete in-kernel firmware") Signed-off-by:

The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family. Fixes: 65e65ec1 ("mlxsw: spectrum_router: Don't ignore IPv6 notifications") Signed-off-by:
