The problem right now is that other cpus can still catch the route being deleted, since there is no rcu grace period between the route deletion and call to fib6_drop_pcpu_from() This can leak the fib6 and associated resources, since no notifier will take care of removing the last reference(s). I decided to add another boolean (fib6_destroying) instead of reusing/renaming exception_bucket_flushed to ease stable backports, and properly document the memory barriers used to implement this fix.

Commit db3bdcb9c3ff ("mac80211: allow AP_VLAN operation on crypto controlled devices") has introduced this change. Since 4addr AP operation also uses AP/VLAN iftype, this conditional way of advertising AP/VLAN support has broken 4addr AP mode operation on crypto controlled devices which do not support VLAN functionality. In the case of ath10k driver, not all firmwares have support for VLAN functionality but all can support 4addr AP operation. Because AP/VLAN support is not advertised for these devices, 4addr AP operations are also blocked. Fix this by allowing 4addr operation on devices which do not support AP/VLAN iftype but can support 4addr AP operation (decision is based on the wiphy flag WIPHY_FLAG_4ADDR_AP).

Usually, we have no need to perform this calculation again, as 1) The GRO implementation guarantees that any packets making it to the udp_rcv_segment() function had correct checksums, and, more importantly, 2) Upon the successful return of udp_rcv_segment(), we immediately pull the UDP header off and either queue the segment to the socket or hand it off to a new protocol handler. Unless userspace has set the IP_CHECKSUM sockopt to indicate that they want the final checksum values, we can pass the needed netdev feature flags to __skb_gso_segment() to avoid checksumming each segment in skb_segment().

Unfortunately the RX resync may get called from soft IRQ, so we can't use the rwsem to protect from the device disappearing. Because we are guaranteed there can be only one resync at a time (it's called from strparser) use a bit to indicate resync is busy and make device removal wait for the bit to get cleared. Note that there is a leftover "flags" field in struct tls_context already. Fixes: 4799ac81e52a ("tls: Add rx inline crypto offload") Signed-off-by: Jakub Kicinski Signed-off-by: David S.

It's caused by Commit 93531c674315 ("net/ipv6: separate handling of FIB entries from dst based routes"), where the cookie can be got only when 'c1'(see below) for setting dst_cookie whereas rt6_check() is called when !'c1' for checking dst_cookie, as we can see in ip6_dst_check(). Since in ip6_dst_check() both rt6_dst_from_check() (c1) and rt6_check() (!c1) will check the 'from' cookie, this patch is to remove the c1 check in rt6_get_cookie(), so that the dst_cookie can always be set properly. c1: (rt->rt6i_flags & RTF_PCPU || unlikely(!list_empty(&rt->rt6i_uncached))) Fixes: 93531c674315 ("net/ipv6: separate handling of FIB entries from dst based routes") Reported-by: Jianlin Shi Signed-off-by: Xin Long Signed-off-by: David S.

I could not reproduce the regression myself, cpus all being spinning on the mm spinlocks for page allocs/freeing, regardless of enabling or disabling the per tcp socket caches. It seems best to disable the feature by default, and let admins enabling it. MM layer either needs to provide scalable order-3 pages allocations, or could attempt a trylock on zone->lock if the caller only attempts to get a high-order page and is able to fallback to order-0 ones in case of pressure.

This forces the stack to send packets with a very high network/cpu overhead. Linux has enforced a minimal value of 48. Since this value includes the size of TCP options, and that the options can consume up to 40 bytes, this means that each segment can include only 8 bytes of payload. In some cases, it can be useful to increase the minimal value to a saner value. We still let the default to 48 (TCP_MIN_SND_MSS), for compatibility reasons. Note that TCP_MAXSEG socket option enforces a minimal value of (TCP_MIN_MSS). David Miller increased this minimal value in commit c39508d6f118 ("tcp: Make TCP_MAXSEG minimum more correct.") from 64 to 88. We might in the future merge TCP_MIN_SND_MSS and TCP_MIN_MSS.

Under syncookie mode, a temporary request socket is used, and req->num_timeout could contain garbage.
