The TX and RX DMA Channels used by the driver to exchange data with CPSW are not guaranteed to be in a clean state during driver initialization. The Bootloader could have used the same DMA Channels without cleaning them up in the event of failure. Thus, reset and disable the DMA Channels to ensure that they are in a clean state before using them.

After the commit d2689b6a ("net: usb: ax88179_178a: avoid two consecutive device resets"), reset operation, in which the default mac address from the device is read, is not executed from bind operation and the random address, that is pregenerated just in case, is direclty written the first time in the device, so the default one from the device is not even read. This writing is not dangerous because is volatile and the default mac address is not missed. In order to avoid this and keep the simplification to have only one reset and reduce the delays, restore the reset from bind operation and remove the reset that is commanded from open operation. The behavior is the same but everything is ready for usbnet_probe. Tested with ASIX AX88179 USB Gigabit Ethernet devices. Restore the old behavior for the rest of possible devices because I don't have the hardware to test. cc: stable@vger.kernel.org # 6.6+ Fixes: d2689b6a ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by:

This reverts commit ad6bcdad. I had nak'd it, and Greg said on the thread that it links that he wasn't going to take it either, especially since it's not his code or his tree, but then, seemingly accidentally, it got pushed up some months later, in what looks like a mistake, with no further discussion in the linked thread.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net: Patch #1 amends a missing spot where the set iterator type is unset. This is fixing a issue in the previous pull request. Patch #2 fixes the delete set command abort path by restoring state of the elements. Reverse logic for the activate (abort) case otherwise element state is not restored, this requires to move the check for active/inactive elements to the set iterator callback. From the deactivate path, toggle the next generation bit and from the activate (abort) path, clear the next generation bitmask. Patch #3 skips elements already restored by delete set command from the abort path in case there is a previous delete element command in the batch. Check for the next generation bit just like it is done via set iteration to restore maps. netfilter pull request 24-04-18 * tag 'nf-24-04-18' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_tables: fix memleak in map from abort path netfilter: nf_tables: restore set elements when delete set fails netfilter: nf_tables: missing iterator type in lookup walk ==================== Link: https://lore.kernel.org/r/20240418010948.3332346-1-pablo@netfilter.orgSigned-off-by:Paolo Abeni <pabeni@redhat.com>

The RX byte accounting for jumbo packets was changed to fix a potential use-after-free bug. However, that fix used the wrong variable and so only accounted for the number of bytes in the final descriptor, not the number of bytes in the whole packet. To fix this, we can simply update our stats with the correct number of bytes before calling napi_gro_receive(). Also rename pkt_len to desc_len in ravb_rx_gbeth() to avoid any future confusion. The variable name pkt_len is correct in ravb_rx_rcar() as that function does not handle packets spanning multiple descriptors.

Paul Barker authored
The RX loops in ravb_rx_gbeth() and ravb_rx_rcar() skip to the next loop iteration if a zero-length descriptor is seen (indicating a DMA mapping error). However, the current RX descriptor index `priv->cur_rx[q]` was incremented at the end of the loop and so would not be incremented when we skip to the next loop iteration. This would cause the loop to keep seeing the same zero-length descriptor instead of moving on to the next descriptor. As the loop counter `i` still increments, the loop would eventually terminate so there is no risk of being stuck here forever - but we should still fix this to avoid wasting cycles. To fix this, the RX descriptor index is incremented at the top of the loop, in the for statement itself. The assignments of `entry` and `desc` are brought into the loop to avoid the need for duplication. Fixes: d8b48911 ("ravb: fix ring memory allocation") Signed-off-by:

The units of "work done" in the RX path should be packets instead of descriptors. Descriptors which are used by the hardware to record error conditions or are empty in the case of a DMA mapping error should not count towards our RX work budget.

The delete set command does not rely on the transaction object for element removal, therefore, a combination of delete element + delete set from the abort path could result in restoring twice the refcount of the mapping. Check for inactive element in the next generation for the delete element command in the abort path, skip restoring state if next generation bit has been already cleared. This is similar to the activate logic using the set walk iterator.

When we removed the hacky start code check we actually didn't took into account that *all* VRAM pages needs to be CPU accessible. Clean up the code and unify the handling into a single helper which checks if the whole resource is CPU accessible. The only place where a partial check would make sense is during eviction, but that is neglitible. Signed-off-by:

From abort path, nft_mapelem_activate() needs to restore refcounters to the original state. Currently, it uses the set->ops->walk() to iterate over these set elements. The existing set iterator skips inactive elements in the next generation, this does not work from the abort path to restore the original state since it has to skip active elements instead (not inactive ones). This patch moves the check for inactive elements to the set iterator callback, then it reverses the logic for the .activate case which needs to skip active elements. Toggle next generation bit for elements when delete set command is invoked and call nft_clear() from .activate (abort) path to restore the next generation bit.

The asid is only erased from the xarray when the vm refcount reaches zero, however this leads to potential UAF since the xe_vm_get() only works on a vm with refcount != 0. Since the asid is allocated in the vm create ioctl, rather erase it when closing the vm, prior to dropping the potential last ref. This should also work when user closes driver fd without explicit vm destroy.
