The RXCHK block will return a partial checksum of 0 if it encounters a problem while receiving a packet. Since a 1's complement sum can only produce this result if no bits are set in the received data stream it is fair to treat it as an invalid partial checksum and not pass it up the stack.

2022-03-17bnx2x: fix built-in kernel driver load failureManish Chopra3-26/+19
Commit b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") added request_firmware() logic in probe() which caused load failure when firmware file is not present in initrd (below), as access to firmware file is not feasible during probe. Direct firmware load for bnx2x/bnx2x-e2-7.13.15.0.fw failed with error -2 Direct firmware load for bnx2x/bnx2x-e2-7.13.21.0.fw failed with error -2 This patch fixes this issue by - 1. Removing request_firmware() logic from the probe() such that .ndo_open() handle it as it used to handle it earlier 2. Given request_firmware() is removed from probe(), so driver has to relax FW version comparisons a bit against the already loaded FW version (by some other PFs of same adapter) to allow different compatible/close enough FWs with which multiple PFs may run with (in different environments), as the given PF who is in probe flow has no idea now with which firmware file version it is going to initialize the device in ndo_open() Link: https://lore.kernel.org/all/46f2d9d9-ae7f-b332-ddeb-b59802be2bab@molgen.mpg.de/ Reported-by: Paul Menzel <pmenzel@molgen.mpg.de> Tested-by: Paul Menzel <pmenzel@molgen.mpg.de> Fixes: b7a49f73059f ("bnx2x: Utilize firmware 7.13.21.0") Signed-off-by: Manish Chopra <manishc@marvell.com> Signed-off-by: Ariel Elior <aelior@marvell.com> Link: https://lore.kernel.org/r/20220316214613.6884-1-manishc@marvell.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-03-11net: add per-cpu storage and net->core_statsEric Dumazet1-2/+2
Before adding yet another possibly contended atomic_long_t, it is time to add per-cpu storage for existing ones: dev->tx_dropped, dev->rx_dropped, and dev->rx_nohandler Because many devices do not have to increment such counters, allocate the per-cpu storage on demand, so that dev_get_stats() does not have to spend considerable time folding zero counters.

2022-03-10net: bcmgenet: Don't claim WOL when its not availableJeremy Linton1-0/+7
Some of the bcmgenet platforms don't correctly support WOL, yet ethtool returns: "Supports Wake-on: gsf" which is false. Ideally if there isn't a wol_irq, or there is something else that keeps the device from being able to wakeup it should display: "Supports Wake-on: d" This patch checks whether the device can wakup, before using the hard-coded supported flags. This corrects the ethtool reporting, as well as the WOL configuration because ethtool verifies that the mode is supported before attempting it.

2022-03-05bnxt_en: Eliminate unintended link toggle during FW resetMichael Chan1-3/+1
If the flow control settings have been changed, a subsequent FW reset may cause the ethernet link to toggle unnecessarily. This link toggle will increase the down time by a few seconds. The problem is caused by bnxt_update_phy_setting() detecting a false mismatch in the flow control settings between the stored software settings and the current FW settings after the FW reset. This mismatch is caused by the AUTONEG bit added to link_info->req_flow_ctrl in an inconsistent way in bnxt_set_pauseparam() in autoneg mode. The AUTONEG bit should not be added to link_info->req_flow_ctrl.

2022-02-20bnxt_en: Increase firmware message response DMA wait timeMichael Chan2-4/+10
When polling for the firmware message response, we first poll for the response message header. Once the valid length is detected in the header, we poll for the valid bit at the end of the message which signals DMA completion. Normally, this poll time for DMA completion is extremely short (0 to a few usec). But on some devices under some rare conditions, it can be up to about 20 msec. Increase this delay to 50 msec and use udelay() for the first 10 usec for the common case, and usleep_range() beyond that. Also, change the error message to include the above delay time when printing the timeout value.

2022-02-05bnx2x: Replace one-element array with flexible-array memberGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.

2022-01-09bnx2x: Remove useless DMA-32 fallback configurationChristophe JAILLET1-15/+4
As stated in [1], dma_set_mask() with a 64-bit mask never fails if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. Moreover, dma_set_mask_and_coherent() returns 0 or -EIO, so the return code of the function can be used directly. Finally, inline bnx2x_set_coherency_mask() because it is now only a wrapper for a single dma_set_mask_and_coherent() call. Simplify code and remove some dead code accordingly.

2022-01-09bnxt_en: use firmware provided max timeout for messagesEdwin Peer6-12/+15
Some older devices cannot accommodate the 40 seconds timeout cap for long running commands (such as NVRAM commands) due to hardware limitations. Allow these devices to request more time for these long running commands, but print a warning, since the longer timeout may cause the hung task watchdog to trigger. In the case of a firmware update operation, this is preferable to failing outright. v2: Use bp->hwrm_cmd_max_timeout directly without the constants.

2022-01-09bnxt_en: improve VF error messages when PF is unavailableEdwin Peer3-9/+40
The current driver design relies on the PF netdev being open in order to intercept the following HWRM commands from a VF: - HWRM_FUNC_VF_CFG - HWRM_CFA_L2_FILTER_ALLOC - HWRM_PORT_PHY_QCFG (only if FW_CAP_LINK_ADMIN is not supported) If the PF is closed, then VFs are subjected to rather inscrutable error messages in response to any configuration requests involving the above command types. Recent firmware distinguishes this problem case from other errors by returning HWRM_ERR_CODE_PF_UNAVAILABLE. In most cases, the appropriate course of action is still to fail, but this can now be accomplished with the aid of more user informative log messages. For L2 filter allocations that are already asynchronous, an automatic retry seems more appropriate. v2: Delete extra newline.

sock.h is pretty heavily used (5k objects rebuilt on x86 after it's touched). We can drop the include of filter.h from it and add a forward declaration of struct sk_filter instead. This decreases the number of rebuilt objects when bpf.h is touched from ~5k to ~1k. There's a lot of missing includes this was masking. Primarily in networking tho, this time.
