2021-04-14ice: print name in /proc/iomemJesse Brandeburg
The driver previously printed it's PCI address in the name field for the pci resource, which when displayed via /proc/iomem, would print the same thing twice. It's more useful for debugging to see the driver name, as most other modules do. Here's a diff of before and after this change: 99100000-991fffff : 0000:3b:00.1 9a000000-a04fffff : PCI Bus 0000:3b 9a000000-9bffffff : 0000:3b:00.1 - 9a000000-9bffffff : 0000:3b:00.1 + 9a000000-9bffffff : ice 9c000000-9dffffff : 0000:3b:00.0 - 9c000000-9dffffff : 0000:3b:00.0 + 9c000000-9dffffff : ice 9e000000-9effffff : 0000:3b:00.1 9f000000-9fffffff : 0000:3b:00.0 a0000000-a000ffff : 0000:3b:00.1 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Tony Brelinski <tonyx.brelinski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2021-04-14ice: manage interrupts during poll exitJesse Brandeburg
The driver would occasionally miss that there were outstanding descriptors to clean when exiting busy/napi poll. This issue has been in the code since the introduction of the ice driver. Attempt to "catch" any remaining work by triggering a software interrupt when exiting napi poll or busy-poll. This will not cause extra interrupts in the case of normal execution. This issue was found when running sfnt-pingpong, with busy poll enabled, and typically with larger I/O sizes like > 8192, the program would occasionally report > 1 second maximums to complete a ping pong.

2021-04-14ice: replace custom AIM algorithm with kernel's DIM libraryJacob Keller
The ice driver has support for adaptive interrupt moderation, an algorithm for tuning the interrupt rate dynamically. This algorithm is based on various assumptions about ring size, socket buffer size, link speed, SKB overhead, ethernet frame overhead and more. The Linux kernel has support for a dynamic interrupt moderation algorithm known as "dimlib". Replace the custom driver-specific implementation of dynamic interrupt moderation with the kernel's algorithm. The Intel hardware has a different hardware implementation than the originators of the dimlib code had to work with, which requires the driver to use a slightly different set of inputs for the actual moderation values, while getting all the advice from dimlib of better/worse, shift left or right. The change made for this implementation is to use a pair of values for each of the 5 "slots" that the dimlib moderation expects, and the driver will program those pairs when dimlib recommends a slot to use. The currently implementation uses two tables, one for receive and one for transmit, and the pairs of values in each slot set the maximum delay of an interrupt and a maximum number of interrupts per second (both expressed in microseconds). There are two separate kinds of bugs fixed by using DIMLIB, one is UDP single stream send was too slow, and the other is that 8K ping-pong was going to the most aggressive moderation and has much too high latency. The overall result of using DIMLIB is that we meet or exceed our performance expectations set based on the old algorithm.

2021-04-14ice: refactor interrupt moderation writesJesse Brandeburg
Introduce several new helpers for writing ITR and GLINT_RATE registers, and refactor the code calling them. This resulted in removal of several duplicate functions and rolled a bunch of simple code back into the calling routines. In particular this removes some code that was doing both a store and a set in a helper function, which seems better done as separate tasks in the caller (and generally takes less lines of code even with a tiny bit of repetition).

2021-04-14Revert "net: stmmac: re-init rx buffers when mac resume back"Thierry Reding
This reverts commit 9c63faaa931e443e7abbbee9de0169f1d4710546, which introduces a suspend/resume regression on Jetson TX2 boards that can be reproduced every time. Given that the issue that this was supposed to fix only occurs very sporadically the safest course of action is to revert before v5.12 and then we can have another go at fixing the more rare issue in the next release (and perhaps backport it if necessary). The root cause of the observed problem seems to be that when the system is suspended, some packets are still in transit. When the descriptors for these buffers are cleared on resume, the descriptors become invalid and cause a fatal bus error.

2021-04-14net: enetc: fetch MAC address from device treeMichael Walle
Normally, the bootloader will already initialize the MAC address registers of the ENETC and the driver will just use them or generate a random one, if it is not initialized. Add a new way to provide the MAC address: via device tree. Besides the usual 'mac-address' property, there is also the possibility to fetch it via a NVMEM provider. The sl28 board stores the MAC address in the SPI NOR flash OTP region. Having this will allow linux to fetch the MAC address from there without being dependent on the bootloader. No in-tree boards have the device tree properties set, thus for these, this is a no-op. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-04-14skbuff: revert "skbuff: remove some unnecessary operation in skb_segment_list()"Paolo Abeni
the commit 1ddc3229ad3c ("skbuff: remove some unnecessary operation in skb_segment_list()") introduces an issue very similar to the one already fixed by commit 53475c5dd856 ("net: fix use-after-free when UDP GRO with shared fraglist"). If the GSO skb goes though skb_clone() and pskb_expand_head() before entering skb_segment_list(), the latter will unshare the frag_list skbs and will release the old list. With the reverted commit in place, when skb_segment_list() completes, skb->next points to the just released list, and later on the kernel will hit UaF. Note that since commit e0e3070a9bc9 ("udp: properly complete L4 GRO over UDP tunnel packet") the critical scenario can be reproduced also receiving UDP over vxlan traffic with: NIC (NETIF_F_GRO_FRAGLIST enabled) -> vxlan -> UDP sink Attaching a packet socket to the NIC will cause skb_clone() and the tunnel decapsulation will call pskb_expand_head().

__ibmvnic_open calls napi_disable without checking whether NAPI polling has already been disabled or not. This could cause napi_disable being called twice, which could generate deadlock. For example, the first napi_disable will spin until NAPI_STATE_SCHED is cleared by napi_complete_done, then set it again. When napi_disable is called the second time, it will loop infinitely because no dev->poll will be running to clear NAPI_STATE_SCHED. To prevent above scenario from happening, call ibmvnic_napi_disable() which checks if napi is disabled or not before calling napi_disable.

2021-04-14dm verity fec: fix misaligned RS roots IOJaegeuk Kim
commit df7b59ba9245 ("dm verity: fix FEC for RS roots unaligned to block size") introduced the possibility for misaligned roots IO relative to the underlying device's logical block size. E.g. Android's default RS roots=2 results in dm_bufio->block_size=1024, which causes the following EIO if the logical block size of the device is 4096, given v->data_dev_block_bits=12: E sd 0 : 0:0:0: [sda] tag#30 request not aligned to the logical block size E blk_update_request: I/O error, dev sda, sector 10368424 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 E device-mapper: verity-fec: 254:8: FEC 9244672: parity read failed (block 18056): -5 Fix this by onlu using f->roots for dm_bufio blocksize IFF it is aligned to v->data_dev_block_bits.

The bit-wise and of the action field with MLX5_ACCEL_ESP_ACTION_DECRYPT is incorrect as MLX5_ACCEL_ESP_ACTION_DECRYPT is zero and not intended to be a bit-flag.
