Ethernet frames can be extracted or injected to or from the device's DDR memory. There is one channel for injection and one channel for extraction. Each of these channels contain a linked list of DCBs which contains DB. The DCB contains only 1 DB for both the injection and extraction. Each DB contains a frame. Every time when a frame is received or transmitted an interrupt is generated. It is not possible to use both the FDMA and the manual injection/extraction of the frames. Therefore the FDMA has priority over the manual because of better performance values.

As such, the code is unmaintained, untested and not in-use by any upstream/distro oriented customers. In order to reduce code complexity, drop the kernel code, clean build config options and delete useless kTLS vs. TLS separation.

Guillaume Nault says: ==================== ipv4: Convert several tos fields to dscp_t Continue the work started with commit a410a0cf ("ipv6: Define dscp_t and stop taking ECN bits into account in fib6-rules") and convert more structure fields and variables to dscp_t. This series focuses on struct fib_rt_info, struct fib_entry_notifier_info and their users (networking drivers). The purpose of dscp_t is to ensure that ECN bits don't influence IP route lookups. It does so by ensuring that dscp_t variables have the ECN bits cleared. Notes: * This series is entirely about type annotation and isn't supposed to have any user visible effect. * The first two patches have to introduce a few dsfield <-> dscp conversions in the affected drivers, but those are then removed when converting the internal driver structures (patches 3-5). In the end, drivers don't have to handle any conversion. ==================== Link: https://lore.kernel.org/r/cover.1649445279.git.gnault@redhat.comSigned-off-by:

Since commit 1771afd4 ("net: cpsw: avoid alignment faults by taking NET_IP_ALIGN into account") the TI CPSW driver was switched to use correct define CPSW_HEADROOM_NA to avoid alignment faults, but there are two places left where CPSW_HEADROOM is still used (without causing issues). Hence, completely drop CPSW_HEADROOM define and use CPSW_HEADROOM_NA everywhere to avoid further mistakes in code. Signed-off-by:

Pablo Neira Ayuso authored
If policy-based routing using the iif selector is used, then the fib expression fails to look up for the reverse path from the prerouting hook because the input interface cannot be inferred. In order to support this scenario, extend the fib expression to allow to use after the route lookup, from the forward hook. This patch also adds support for the input hook for usability reasons. Since the prerouting hook cannot be used for the scenario described above, users need two rules: one for the forward chain and another rule for the input chain to check for the reverse path check for locally targeted traffic.

Menglong Dong says: ==================== net: icmp: add skb drop reasons to icmp In the commit c504e5c2 ("net: skb: introduce kfree_skb_reason()"), we added the support of reporting the reasons of skb drops to kfree_skb tracepoint. And in this series patches, reasons for skb drops are added to ICMP protocol. In order to report the reasons of skb drops in 'sock_queue_rcv_skb()', the function 'sock_queue_rcv_skb_reason()' is introduced in the 1th patch, which is used in the 3th patch. As David Ahern suggested, the reasons for skb drops should be more general and not be code based. Therefore, in the 2th patch, SKB_DROP_REASON_PTYPE_ABSENT is renamed to SKB_DROP_REASON_UNHANDLED_PROTO, which is used for the cases of no L3 protocol handler, no L4 protocol handler, version extensions, etc. In the 3th patch, we introduce the new function __ping_queue_rcv_skb() to report drop reasons by its return value and keep the return value of ping_queue_rcv_skb() still. In the 4th patch, we make ICMP message handler functions return drop reasons, which means we change the return type of 'handler()' in 'struct icmp_control' from 'bool' to 'enum skb_drop_reason'. This changed its original intention, as 'false' means failure, but 'SKB_NOT_DROPPED_YET', which is 0, means success now. Therefore, we have to change all usages of these handler. Following "handler" functions are involved: icmp_unreach() icmp_redirect() icmp_echo() icmp_timestamp() icmp_discard() And following drop reasons are added(what they mean can be see in the document for them): SKB_DROP_REASON_ICMP_CSUM SKB_DROP_REASON_INVALID_PROTO The reason 'INVALID_PROTO' is introduced for the case that the packet doesn't follow rfc 1122 and is dropped. I think this reason is different from the 'UNHANDLED_PROTO', as the 'UNHANDLED_PROTO' means the packet is fine, and it is just not supported. This is not a common case, and I believe we can locate the problem from the data in the packet. For now, this 'INVALID_PROTO' is used for the icmp broadcasts with wrong types. Maybe there should be a document file for these reasons. For example, list all the case that causes the 'INVALID_PROTO' drop reason. Therefore, users can locate their problems according to the document. Changes since v4: - rename SKB_DROP_REASON_RFC_1122 to SKB_DROP_REASON_INVALID_PROTO Changes since v3: - rename SKB_DROP_REASON_PTYPE_ABSENT to SKB_DROP_REASON_UNHANDLED_PROTO in the 2th patch - fix the return value problem of ping_queue_rcv_skb() in the 3th patch - remove SKB_DROP_REASON_ICMP_TYPE and SKB_DROP_REASON_ICMP_BROADCAST and introduce the SKB_DROP_REASON_RFC_1122 in the 4th patch Changes since v2: - fix aliegnment problem in the 2th patch Changes since v1: - introduce __ping_queue_rcv_skb() instead of change the return value of ping_queue_rcv_skb() in the 2th patch, as Paolo suggested ==================== Signed-off-by:

As the return value of 'sock_queue_rcv_skb()' is used as the error code, we can't make it as drop reason and have to pass extra output argument. 'sock_queue_rcv_skb()' is used in many places, so we can't change it directly. Introduce the new function 'sock_queue_rcv_skb_reason()' and make 'sock_queue_rcv_skb()' an inline call to it.

Jakub Kicinski authored
The current invese logic is harder to follow (and adds extra tests to the fast path). We have to enumerate all cases which need to keep the skb before consuming it. It's simpler to jump out of the full record flow as we detect those cases. This makes it clear that partial consumption and peek can only reach end of the function thru the !zc case so move the code up there. Signed-off-by:

Whatever we do in the loop the skb should not remain on as ctx->recv_pkt afterwards. We can clear that pointer and restart strparser earlier.

tls_sw_advance_skb() always consumes the skb at the end of the loop. To fall here the following must be true: !async && !is_peek && !retain_skb retain_skb => !zc && rxm->full_len > len # but non-full record implies !zc, so above can be simplified as retain_skb => rxm->full_len > len !async && !is_peek && !(rxm->full_len > len) !async && !is_peek && rxm->full_len <= len tls_sw_advance_skb() returns false if len < rxm->full_len which can't be true given conditions above.
