Infiniband clients must be attached and detached in a specific order in ibcore.

2020-07-06T08:50:11Z

Currently the linking order of the infiniband, IB, modules decide in which order the clients are attached and detached. For example one IB client may use resources from another IB client. This can lead to a potential deadlock at shutdown. For example if the ipoib is unregistered after the ib_multicast client is detached, then if ipoib is using multicast addresses a deadlock may happen, because ib_multicast will wait for all its resources to be freed before returning from the remove method. Fix this by using module_xxx_order() instead of module_xxx(). Differential Revision: https://reviews.freebsd.org/D23973 MFC after: 1 week Sponsored by: Mellanox Technologies

Allow multicast packets to be received in promiscious mode, in mlx4en(4).

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

2020-02-26T14:26:36Z

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718

Widen EPOCH(9) usage in mlx4en(4).

2020-01-31T10:41:47Z

Make sure all receive completion callbacks are covered by the network EPOCH(9), because this is required when calling if_input() and ether_input() after r357012. Convert some spaces to tabs while at it. Sponsored by: Mellanox Technologies

Split out a more generic debugnet(4) from netdump(4)

2019-10-17T16:23:03Z

Debugnet is a simplistic and specialized panic- or debug-time reliable datagram transport. It can drive a single connection at a time and is currently unidirectional (debug/panic machine transmit to remote server only). It is mostly a verbatim code lift from netdump(4). Netdump(4) remains the only consumer (until the rest of this patch series lands). The INET-specific logic has been extracted somewhat more thoroughly than previously in netdump(4), into debugnet_inet.c. UDP-layer logic and up, as much as possible as is protocol-independent, remains in debugnet.c. The separation is not perfect and future improvement is welcome. Supporting INET6 is a long-term goal. Much of the diff is "gratuitous" renaming from 'netdump_' or 'nd_' to 'debugnet_' or 'dn_' -- sorry. I thought keeping the netdump name on the generic module would be more confusing than the refactoring. The only functional change here is the mbuf allocation / tracking. Instead of initiating solely on netdump-configured interface(s) at dumpon(8) configuration time, we watch for any debugnet-enabled NIC for link activation and query it for mbuf parameters at that time. If they exceed the existing high-water mark allocation, we re-allocate and track the new high-water mark. Otherwise, we leave the pre-panic mbuf allocation alone. In a future patch in this series, this will allow initiating netdump from panic ddb(4) without pre-panic configuration. No other functional change intended.

Include eventhandler.h in more compilation units

2019-05-21T01:18:43Z

This was enumerated with exhaustive search for sys/eventhandler.h includes, cross-referenced against EVENTHANDLER_* usage with the comm(1) utility. Manual checking was performed to avoid redundant includes in some drivers where a common os_bsd.h (for example) included sys/eventhandler.h indirectly, but it is possible some of these are redundant with driver-specific headers in ways I didn't notice. (These CUs did not show up as missing eventhandler.h in tinderbox.) X-MFC-With: r347984
