Patch 1 adds a missing error message. Patch 2 prints manufacturing info to logs in case PCI VPD capability is not programmed correctly. Patches 3 and 4 allow reporting NSP ABI version in ethtool -i. Patch 5 allows dumping flash application logs. Patches 6 and 7 provides a way of application firmwares to declare limited SR-IOV support. v2: put some of the code in patch 7 in #ifdef CONFIG_PCI_SRIOV (Yuval). ==================== Signed-off-by: NDavid S.

Some application firmware projects may choose to limit the number of VFs available below what is specified in PCI capability to be able to reuse the PCIe interface resources. There may also be projects which use cases don't require SR-IOV support at all and therefore don't want to spend time implementing/testing it. Check nfd_vf_cfg_max_vfs firmware symbol to see if application firmware is reporting how many VFs it supports. This mechanism is an opt-in, if symbol is not present we will only look at the PCI capability values. Signed-off-by: NJakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: NDavid S.

Resizing currently drops consumer lock. This can cause entries to be reordered, which isn't good in itself. More importantly, consumer can detect a false ring empty condition and block forever. Further, nesting of consumer within producer lock is problematic for tun, since it produces entries in a BH, which causes a lock order reversal: CPU0 CPU1 ---- ---- consume: lock(&(&r->consumer_lock)->rlock); resize: local_irq_disable(); lock(&(&r->producer_lock)->rlock); lock(&(&r->consumer_lock)->rlock); <Interrupt> produce: lock(&(&r->producer_lock)->rlock); To fix, nest producer lock within consumer lock during resize, and keep consumer lock during the whole swap operation.

This patch is to add support for MSG_MORE on sctp. It adds force_delay in sctp_datamsg to save MSG_MORE, and sets it after creating datamsg according to the send flag. sctp_packet_can_append_data then uses it to decide if the chunks of this msg will be sent at once or delay it. Note that unlike [1], this patch saves MSG_MORE in datamsg, instead of in assoc. As sctp enqueues the chunks first, then dequeue them one by one. If it's saved in assoc,the current msg's send flag (MSG_MORE) may affect other chunks' bundling. Since last patch, sctp flush out queue once assoc state falls into SHUTDOWN_PENDING, the close block problem mentioned in [1] has been solved as well.

This patch is to flush out queue when assoc state falls into SHUTDOWN_PENDING if there are still chunks in it, so that the data can be sent out as soon as possible before sending SHUTDOWN chunk. When sctp supports MSG_MORE flag in next patch, this improvement can also solve the problem that the chunks with MSG_MORE flag may be stuck in queue when closing an assoc.

There are number of function calls, originating from user-space, typically through the Ethernet driver that can make us crash by dereferencing phydev->drv which will be NULL once we unbind the driver from the PHY.

sctp has changed to use rhlist for transport rhashtable since commit 7fda702f ("sctp: use new rhlist interface on sctp transport rhashtable"). But rhltable_insert_key doesn't check the duplicate node when inserting a node, unlike rhashtable_lookup_insert_key. It may cause duplicate assoc/transport in rhashtable. like: client (addr A, B) server (addr X, Y) connect to X INIT (1) ------------> connect to Y INIT (2) ------------> INIT_ACK (1) <------------ INIT_ACK (2) <------------ After sending INIT (2), one transport will be created and hashed into rhashtable. But when receiving INIT_ACK (1) and processing the address params, another transport will be created and hashed into rhashtable with the same addr Y and EP as the last transport. This will confuse the assoc/transport's lookup. This patch is to fix it by returning err if any duplicate node exists before inserting it.

Now when sending a packet, sctp_transport_dst_check will check if dst is obsolete by calling ipv4/ip6_dst_check. But they return obsolete only when adding a new cache, after that when the cache's pmtu is updated again, it will not trigger transport->dst/pmtu's update. It can be reproduced by reducing route's pmtu twice. At the 1st time client will add a new cache, and transport->pathmtu gets updated as sctp_transport_dst_check finds it's obsolete. But at the 2nd time, cache's mtu is updated, sctp client will never send out any packet, because transport->pmtu has no chance to update. This patch is to fix this by also checking if transport pmtu is dst mtu in sctp_transport_dst_check, so that transport->pmtu can be updated on time.
