2008-02-04mlx4_core: Don't read reserved fields in mlx4_QUERY_ADAPTER()Jack Morgenstein
The firmware QUERY_ADAPTER command does not return vendor_id, device_id, and revision_id; eliminate these fields from the query. Initialize the rev_id field of the mlx4 device via init_node_data (MAD IFC query), as is done in the query_device verb implementation.

2008-02-04mlx4_core: Fix more section mismatchesRoland Dreier
Commit 3d73c288 ("mlx4_core: Fix section mismatches") fixed some of the section mismatches introduced when error recovery was added, but there were still more cases of errory recovery code calling into __devinit code from regular .text. Fix this by getting rid of the now-incorrect __devinit annotations. Signed-off-by: Roland Dreier <rolandd@cisco.com>

Fix bug found by Christian Borntraeger: if the other side fills all the registered network buffers before we enable NAPI, we will never get an interrupt. The simplest fix is to process the input queue once on open. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2008-02-04virtio: reset functionRusty Russell
A reset function solves three problems: 1) It allows us to renegotiate features, eg. if we want to upgrade a guest driver without rebooting the guest. 2) It gives us a clean way of shutting down virtqueues: after a reset, we know that the buffers won't be used by the host, and 3) It helps the guest recover from messed-up drivers. So we remove the ->shutdown hook, and the only way we now remove feature bits is via reset. We leave it to the driver to do the reset before it deletes queues: the balloon driver, for example, needs to chat to the host in its remove function. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: populate network rings in the probe routine, not openRusty Russell
Since we want to reset the device to remove them, this is simpler (device is reset for us on driver remove). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: Tweak virtio_net definesRusty Russell
1) Turn GSO on virtio net into an all-or-nothing (keep checksumming separate). Having multiple bits is a pain: if you can't support something you should handle it in software, which is still a performance win. 2) Make VIRTIO_NET_HDR_GSO_ECN a flag in the header, so it can apply to IPv6 or v4. 3) Rename VIRTIO_NET_F_NO_CSUM to VIRTIO_NET_F_CSUM (ie. means we do checksumming). 4) Add csum and gso params to virtio_net to allow more testing. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: Net header needs hdr_lenRusty Russell
It's far easier to deal with packets if we don't have to parse the packet to figure out the header length to know how much to pull into the skb data. Add the field to the virtio_net_hdr struct (and fix the spaces that somehow crept in there). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: explicit enable_cb/disable_cb rather than callback return.Rusty Russell
It seems that virtio_net wants to disable callbacks (interrupts) before calling netif_rx_schedule(), so we can't use the return value to do so. Rename "restart" to "cb_enable" and introduce "cb_disable" hook: callback now returns void, rather than a boolean. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-02-04virtio: simplify config mechanism.Rusty Russell
Previously we used a type/len pair within the config space, but this seems overkill. We now simply define a structure which represents the layout in the config space: the config space can now only be extended at the end. The main driver-visible changes: 1) We indicate what fields are present with an explicit feature bit. 2) Virtqueues are explicitly numbered, and not in the config space.

2008-02-03forcedeth: checksum fixAyaz Abdulla
The driver should inform the stack when checksum has been performed by the HW when both IP and TCP (or UDP) checksum flags are indicated by HW. Previously, it would also inform the stack when only IP checksum flag was indicated by HW. This can cause data corruption when IP fragments are used. The IP Identification field can wrap around and cause data from new fragments to fill into older fragment slots with same IP Id. The stack would then not perform TCP/UDP checksum (after re-assembly of all fragments) since driver falsely stated it was already calculated.

2008-02-03bonding: do not acquire rtnl in ARP monitorJay Vosburgh
The ARP monitor functions currently acquire RTNL when performing failover operations, but do so incorrectly (out of order). This causes various warnings from might_sleep.

2008-02-03bonding: fix race that causes invalid statisticsAndy Gospodarek
I've seen reports of invalid stats in /proc/net/dev for bonding interfaces, and found it's a pretty easy problem to reproduce. Since the current code zeros the bonding stats when a read is requested and a pointer to that data is returned to the caller we cannot guarantee that the caller has completely accessed the data before a successive call to request the stats zeroes the stats again. This patch creates a new stack variable to keep track of the updated stats and copies the data from that variable into the bonding stats structure. This ensures that the value for any of the bonding stats should not incorrectly return zero for any of the bonding statistics. This does use more stack space and require an extra memcpy, but it seems like a fair trade-off for consistently correct bonding statistics.
