This patch modifies ixgbe_debugfs.c and the Makefile for the ixgbe driver to only compile the file when the config is enabled. This means we can remove the #ifdef inside the ixgbe_debugfs.c file. Signed-off-by:

This change is meant to inline the Rx PTP descriptor handling. The main motivation is to avoid unnecessary jumps into function calls that we then immediately exit because we are not performing timestamps. The net result of this change is that ixgbe_ptp_rx_tstamp drops from .5% CPU utilization in my performance runs to 0%, and the only value tested is the Rx descriptor which should already be warm in the cache if not stored in a register.

This patch corrects a bug introduced by commit f3444d8b. The rxmtrl value for the UDP port to timestamp on was moved above the switch statement, but was overwritten to 0 if the ioctl selected one of the V1 filters. Signed-off-by:

This patch copies the igb implementation of Tx timestamps, which uses a work item to poll for the Tx timestamp. In addition it adds a timeout value of 15 seconds, after which it will stop polling. This is necessary due to an issue with the descriptor being marked done before the Tx timestamp event has occurred. These two events don't correlate, so using the done bit on the descriptor as indication that the timestamp must already have been taken leads to potentially dropped Tx timestamps (especially under heavy packet load) Reported-by:

This patch removes ixgbe_ptp_match, and the corresponding packet filtering from ixgbe driver. This code was previously causing some issues within the hotpath of the driver. However the code also provided a check against possible frozen Rx timestamp due to dropped packets when the Rx ring is full. This patch provides a replacement solution based on the watchdog. To this end, whenever a packet consumes the Rx timestamp it stores the jiffy value in the rx_ring structure. Watchdog updates its own jiffy timer whenever there is no valid timestamp in the registers. If watchdog detects a valid timestamp in the registers, (meaning that no Rx packet has consumed it yet) it will check which time is most recent, the last time in the watchdog, or any time in the rx_rings. If the most recent "event" was more than 5seconds ago, it will flush the Rx timestamp and print a warning message to the syslog. Reported-by:

This patch updates the filters for ethtool's get_ts_info to return support for all filters which can be supported by upscaling to ptp_v2_event. The intent behind this change is due to reasoning that we do in fact support the filters. (hwtstamp_ioctl returns success after setting the filter to the upscaled version). In this way we can remain consistent over which filters are supported via the get_ts_info ioctl and which filters are in practice actually supported. Signed-off-by:

This patch cleans up the ethtool diagnostics test by ensuring that the tests work properly regardless of what state the adapter was in. The SRIOV VF check is done at the beginning, forgoing the link test. The if_running -> dev_close is moved before the link test, as well as a call to enable the Tx laser. This ensures that the link test will return valid results even when adapter was previously down. Also, a call to disable the Tx laser is added if the device was down before the start. This ensures consistent behavior of the Tx laser before and after the diagnostic checks. The end result is consistent behavior regardless of device state. Signed-off-by:

When posting a message on the bulletin board, the PF calculates crc over the message and places the result in the message. When the VF samples the Bulletin Board it copies the message aside and validates this crc. The length of the message is crucial here and must be the same in both parties. Since the PF is running in the Hypervisor and the VF is running in a Vm, they can possibly be of different versions. As the Bulletin Board is designed to grow forward in future versions, in the VF the length must not be the size of the message structure but instead it should be a field in the message itself.

In INTA mode, cnic and bnx2x share the same IRQ. During chip reset, for example, cnic will stop servicing IRQs after it has shutdown the cnic hardware resources. However, the shared IRQ is still active as bnx2x needs to finish the reset. There is a window when bnx2x does not know that cnic is no longer handling IRQ and things don't always work properly. Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set before the first cnic IRQ is expected and cleared when no more cnic IRQs are expected, so there should be no race conditions.

Tom Herbert says: ==================== This series implements so_reuseport (SO_REUSEPORT socket option) for TCP and UDP. For TCP, so_reuseport allows multiple listener sockets to be bound to the same port. In the case of UDP, so_reuseport allows multiple sockets to bind to the same port. To prevent port hijacking all sockets bound to the same port using so_reuseport must have the same uid. Received packets are distributed to multiple sockets bound to the same port using a 4-tuple hash. The motivating case for so_resuseport in TCP would be something like a web server binding to port 80 running with multiple threads, where each thread might have it's own listener socket. This could be done as an alternative to other models: 1) have one listener thread which dispatches completed connections to workers. 2) accept on a single listener socket from multiple threads. In case #1 the listener thread can easily become the bottleneck with high connection turn-over rate. In case #2, the proportion of connections accepted per thread tends to be uneven under high connection load (assuming simple event loop: while (1) { accept(); process() }, wakeup does not promote fairness among the sockets. We have seen the disproportion to be as high as 3:1 ratio between thread accepting most connections and the one accepting the fewest. With so_reusport the distribution is uniform. The TCP implementation has a problem in that the request sockets for a listener are attached to a listener socket. If a SYN is received, a listener socket is chosen and request structure is created (SYN-RECV state). If the subsequent ack in 3WHS does not match the same port by so_reusport, the connection state is not found (reset) and the request structure is orphaned. This scenario would occur when the number of listener sockets bound to a port changes (new ones are added, or old ones closed). We are looking for a solution to this, maybe allow multiple sockets to share the same request table... The motivating case for so_reuseport in UDP would be something like a DNS server. An alternative would be to recv on the same socket from multiple threads. As in the case of TCP, the load across these threads tends to be disproportionate and we also see a lot of contection on the socket lock. Note that SO_REUSEADDR already allows multiple UDP sockets to bind to the same port, however there is no provision to prevent hijacking and nothing to distribute packets across all the sockets sharing the same bound port. This patch does not change the semantics of SO_REUSEADDR, but provides usable functionality of it for unicast. ==================== Signed-off-by:

Paul Gortmaker says: ==================== The Ethernet-HowTo was maintained for roughly 10 years, from 1993 to 2003. Fortunately sane hardware probing and auto detection (via PCI and ISA/PnP) largely made the document a relic of the past, hence it being abandoned a decade ago. However, there is one last useful thing that we can extract from the effort made in maintaining that document. We can use it to guide us with respect to what rare, experimental and/or super ancient 10Mbit ISA drivers don't make sense to maintain in-tree anymore. Nobody will argue that ISA is obsolete. Availability went away at about the time Pentium3 motherboards moved from 500MHz Slot1/SECC processors to the green 500MHz Socket 370 Pentium3 chips, at the turn of the century. In theory, it is possible that someone could still be running one of these 12+ year old P3 machines and want 3.9+ bleeding edge kernels (but unlikely). In light of the above (remote) possibility, we can defer the removal of some ISA network drivers that were highly popular and well tested. Typically that means the stuff more from the mid to late '90s, some with ISA PnP support, like the 3c509, the wd/SMC 8390 based stuff, PCnet/lance etc. But a lot of other drivers, typically from the early 1990s were for rare hardware, and experimental (to the point of requiring a cron job that would do a test ping, and then ifconfig down/up and/or a rmmod/insmod!). And some of these drivers (znet, and lp486e to name two) are physically tied to platforms with on motherboard ethernet -- of 486 machines that date from the early 1990s and can only have single digit amounts of memory. What I'd like to achieve here with this series, is to get rid of those old drivers that are no longer being used. In an earlier discussion where I'd proposed deleting a single driver, Alan suggested we instead dump all the historical stuff in one go, to make it "...immediately obvious where the break point is..."[1] and that it was "perfectly reasonable it (and a pile of other ISA cards) ought to be shown the door"[2]. So that is the goal here - make a clear line in the sand where the really ancient stuff finally gets kicked to the curb. Two old parallel port drivers are considered for removal here as well, since in early 386/486 ISA machines, the parallel port was typically found with the UARTS on the multi-I/O ISA controller card. These drivers also date from the early 1990's; parallel ports are no longer found on modern boards, and their performance was not even capable of 10% of 10Mbit bandwidth. Allow me a preemptive justification against the inevitable comments from well meaning bystanders who suggest "why not just leave all this alone?". Dead drivers cost us all if they are left in tree. If you think that is false, then please first consider: -every time you type "git status", you are checking to see if modifications have been made by you to all that dead code. -every time you type "git grep <regex>" you are searching through files which contain that dead code that simply does not interest you. -every time you build a "allyesconfig" and an "allmodconfig" (don't tell me you skip this step before submitting your changes to a maintainer), you waste CPU cycles building this dead code. -every time there is a tree wide API change, or cleanup, or file relocation, we pay the cost of updating dead code, or moving dead code. -daily regression tests (take linux-next as the most transparent example) spend time building (and possibly running) this dead code. -hard working people who regularly run auditing tools looking for lurking bugs (sparse/coverity/smatch/coccinelle) are wasting time checking for, and fixing bugs in this dead code. This last one is key. Please take a look at the git history for the files that are proposed for removal here. Look at the git history for any one of them ("git whatchanged --follow drivers/net/.../driver.c") Mentally sort the changes into two bins -- (1) the robotic tree-wide changes, and (2) the "look I found a real run-time bug while using this" category. You will see that category #2 is essentially empty. Further to that, realize that drivers don't simply disappear. We are not operating in the binary-only distribution space like other OS. All these drivers remain in the git history forever. If a person is an enthusiast for extreme legacy hardware, they are probably already customizing their kernel source and building it themselves to support such systems. Also keep in mind that they could still build the 3.8 kernel exactly as-is, and run it (or a 3.8.x stable variant of it) for several more years if they were really determined to cling to these old experimental ISA drivers for some reason. In summary, I hope that folks can be pragmatic about this, and not get swept up in nostalgia. Ask yourself whether it is realistic to expect a person would have a genuine use case where they would need to build a 3.9+ modern kernel and install it on some legacy hardware that has no option but to absolutely _require_ one of the drivers that are deleted here. The following series was created with --irreversible-delete for ease of review (it skips showing the content of files that are deleted); however the complete patches can be pulled as per below. ==================== Signed-off-by:

Since we have removed NCE (Neighbour Cache Entry) reference from routing entries, the only refcnt holders of an NCE are its timer (if running) and its owner table, in usual cases. As a result, neigh_periodic_work() purges NCEs over and over again even for gateways. It does not make sense to purge entries, if number of them is very small, so keep them. The minimum number of entries to keep is specified by gc_thresh1. Signed-off-by:

The last update to the Ethernet HowTo (over 10 years ago) listed this: ------------------------ SEEQ 8005 Status: Obsolete, Driver Name: seeq8005 There is little information about the card included in the driver, and hence little information to be put here. If you have a question, you are probably best trying to e-mail the driver author as listed in the source. It was marked obsolete as of the 2.4 series kernels. ------------------------ If it was obsolete over a decade ago, the situation can not have improved with the passage of time, so let us act on that. Even with today's improved search engines, I was unable to locate any real meaningful information on the ISA implementation of this rare chip. There are ARM and SGI variants of the driver in tree, but they do not depend on the original x86 driver source or header file. We leave those non-x86 drivers to be deleted by the arch maintainers when they decide to expire those legacy platforms as a whole. Signed-off-by:
