2021-06-18net: dsa: sja1105: properly power down the microcontroller clock for SJA1110Vladimir Oltean4-16/+53
It turns out that powering down the BASE_TIMER_CLK does not turn off the microcontroller, just its timers, including the one for the watchdog. So the embedded microcontroller is still running, and potentially still doing things. To prevent unwanted interference, we should power down the BASE_MCSS_CLK as well (MCSS = microcontroller subsystem). The trouble is that currently we turn off the BASE_TIMER_CLK for SJA1110 from the .clocking_setup() method, mostly because this is a Clock Generation Unit (CGU) setting which was traditionally configured in that method for SJA1105. But in SJA1105, the CGU was used for bringing up the port clocks at the proper speeds, and in SJA1110 it's not (but rather for initial configuration), so it's best that we rebrand the sja1110_clocking_setup() method into what it really is - an implementation of the .disable_microcontroller() method. Since disabling the microcontroller only needs to be done once, at probe time, we can choose the best place to do that as being in sja1105_setup(), before we upload the static config to the device. This guarantees that the static config being used by the switch afterwards is really ours. Note that the procedure to upload a static config necessarily resets the switch. This already did not reset the microcontroller, only the switch core, so since the .disable_microcontroller() method is guaranteed to be called by that point, if it's disabled, it remains disabled. Add a comment to make that clear. With the code movement for SJA1110 from .clocking_setup() to .disable_microcontroller(), both methods are optional and are guarded by "if" conditions. Tested by enabling in the device tree the rev-mii switch port 0 that goes towards the microcontroller, and flashing a firmware that would have networking. Without this patch, the microcontroller can be pinged, with this patch it cannot. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-06-18net: ll_temac: Avoid ndo_start_xmit returning NETDEV_TX_BUSYEsben Haabendal1-0/+5
As documented in Documentation/networking/driver.rst, the ndo_start_xmit method must not return NETDEV_TX_BUSY under any normal circumstances, and as recommended, we simply stop the tx queue in advance, when there is a risk that the next xmit would cause a NETDEV_TX_BUSY return.

2021-06-18net: ll_temac: Fix TX BD buffer overwriteEsben Haabendal1-1/+1
Just as the initial check, we need to ensure num_frag+1 buffers available, as that is the number of buffers we are going to use. This fixes a buffer overflow, which might be seen during heavy network load. Complete lockup of TEMAC was reproducible within about 10 minutes of a particular load.

2021-06-18net: ll_temac: Add memory-barriers for TX BD accessEsben Haabendal1-1/+13
Add a couple of memory-barriers to ensure correct ordering of read/write access to TX BDs. In xmit_done, we should ensure that reading the additional BD fields are only done after STS_CTRL_APP0_CMPLT bit is set. When xmit_done marks the BD as free by setting APP0=0, we need to ensure that the other BD fields are reset first, so we avoid racing with the xmit path, which writes to the same fields. Finally, making sure to read APP0 of next BD after the current BD, ensures that we see all available buffers. Signed-off-by: Esben Haabendal <esben@geanix.com> Signed-off-by: David S.

2021-06-18net: ll_temac: Make sure to free skb when it is completely usedEsben Haabendal1-1/+5
With the skb pointer piggy-backed on the TX BD, we have a simple and efficient way to free the skb buffer when the frame has been transmitted. But in order to avoid freeing the skb while there are still fragments from the skb in use, we need to piggy-back on the TX BD of the skb, not the first. Without this, we are doing use-after-free on the DMA side, when the first BD of a multi TX BD packet is seen as completed in xmit_done, and the remaining BDs are still being processed.

2021-06-18ice: report hash type such as L2/L3/L4Jesse Brandeburg5-126/+50
The hardware is reporting the type of the hash used for RSS as a PTYPE field in the receive descriptor. Use this value to set the skb packet hash type by extending the hash type table to cover all 10-bits of possible values (requiring some variables to be changed from u8 to u16), and then use that table to convert to one of the possible values in enum pkt_hash_types. While we're here, remove the unused ptype struct value, which makes table init easier for the zero entries, and use ranged initializer to remove a bunch of code (works with gcc and clang). Without this change, the kernel will recalculate the hash in software, which can consume extra CPU cycles.

The source (&dcbx_info->operational.params) and dest (&p_hwfn->p_dcbx_info->set.config.params) are both struct qed_dcbx_params (560 bytes), not struct qed_dcbx_admin_params (564 bytes), which is used as the memcpy() size. However it seems that struct qed_dcbx_operational_params (dcbx_info->operational)'s layout matches struct qed_dcbx_admin_params (p_hwfn->p_dcbx_info->set.config)'s 4 byte difference (3 padding, 1 byte for "valid"). On the assumption that the size is wrong (rather than the source structure type), adjust the memcpy() size argument to be 4 bytes smaller and add a BUILD_BUG_ON() to validate any changes to the structure sizes.

My local syzbot instance hit memory leak in mkiss_open()[1]. The problem was in missing free_netdev() in mkiss_close(). In mkiss_open() netdevice is allocated and then registered, but in mkiss_close() netdevice was only unregistered, but not freed.

If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it must be undone by a corresponding 'pci_disable_pcie_error_reporting()' call, as already done in the remove function.

2021-06-17net: pcs: xpcs: Fix a less than zero u16 comparison errorColin Ian King1-6/+6
Currently the check for the u16 variable val being less than zero is always false because val is unsigned. Fix this by using the int variable for the assignment and less than zero check.
