2022-11-07net: mv643xx_eth: support MII/GMII/RGMII modes for KirkwoodDavid Yang
Support mode switch properly, which is not available before. If SoC has two Ethernet controllers, by setting both of them into MII mode, the first controller enters GMII mode, while the second controller is effectively disabled. This requires configuring (and maybe enabling) the second controller in the device tree, even though it cannot be used. Signed-off-by: David Yang <mmyangfl@gmail.com> Signed-off-by: David S.

2022-11-04sfc: check recirc_id match caps before MAE offloadEdward Cree
Offloaded TC rules always match on recirc_id in the MAE, so we should check that the MAE reported support for this match before attempting to insert the rule. These checks allow us to fail early, avoiding the PCIe round-trip to firmware for an MC_CMD_MAE_ACTION_RULE_INSERT that will only fail, and more importantly providing a more informative error message that identifies which match field is unsupported.

2022-11-04net: fman: Unregister ethernet device on removalSean Anderson
When the mac device gets removed, it leaves behind the ethernet device. This will result in a segfault next time the ethernet device accesses mac_dev. Remove the ethernet device when we get removed to prevent this. This is not completely reversible, since some resources aren't cleaned up properly, but that can be addressed later.

2022-11-04net: ethernet: renesas: Fix return type of rswitch_start_xmit()Nathan Chancellor
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A proposed warning in clang aims to catch these at compile time, which reveals: drivers/net/ethernet/renesas/rswitch.c:1533:20: error: incompatible function pointer types initializing 'netdev_tx_t (*)(struct sk_buff *, struct net_device *)' (aka 'enum netdev_tx (*)(struct sk_buff *, struct net_device *)') with an expression of type 'int (struct sk_buff *, struct net_device *)' [-Werror,-Wincompatible-function-pointer-types-strict] .ndo_start_xmit = rswitch_start_xmit, ^~~~~~~~~~~~~~~~~~ 1 error generated. ->ndo_start_xmit() in 'struct net_device_ops' expects a return type of 'netdev_tx_t', not 'int'. Adjust the return type of rswitch_start_xmit() to match the prototype's to resolve the warning and CFI failure.

2022-11-04bnxt_en: fix potentially incorrect return value for ndo_rx_flow_steerAlex Barba
In the bnxt_en driver ndo_rx_flow_steer returns '0' whenever an entry that we are attempting to steer is already found. This is not the correct behavior. The return code should be the value/index that corresponds to the entry. Returning zero all the time causes the RFS records to be incorrect unless entry '0' is the correct one. As flows migrate to different cores this can create entries that are not correct. Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")

According to Realtek programmers, "to adjust oscillator to align central frequency of connected AP. Then, it can yield better performance." From commit fb8517f4fade ("rtw88: 8822c: add CFO tracking"). The RTL8192CU and a version of RTL8723AU apparently don't have the ability to adjust the oscillator, so this doesn't apply to them. This also doesn't apply to the wifi + bluetooth combo chips (RTL8723AU and RTL8723BU) because the CFO tracking should only be done when bluetooth is disabled, and determining that looked complicated. That leaves only the RTL8192EU and RTL8188FU chips. I tested this with the latter.

2022-11-04bcma: Use the proper gpio includeLinus Walleij
The <linux/bcma/bcma_driver_chipcommon.h> is including the legacy header <linux/gpio.h> to obtain struct gpio_chip. Instead, include <linux/gpio/driver.h> where this struct is defined. It turns out that the brcm80211 brcmsmac depends on this to bring in the symbol gpio_is_valid(). The driver looks up the BCMA parent GPIO driver and checks that this succeeds, but then it goes on to use the deprecated GPIO call gpio_is_valid() to check the consistency of the .base member of the BCMA GPIO struct. The whole check can be dropped because the bcma_gpio is initialized in the declarations: struct gpio_chip *bcma_gpio = &cc_drv->gpio; And this can never be NULL.

2022-11-04wifi: brcmfmac: Fix potential shift-out-of-bounds in brcmf_fw_alloc_request()Minsuk Kang
This patch fixes a shift-out-of-bounds in brcmfmac that occurs in BIT(chiprev) when a 'chiprev' provided by the device is too large. It should also not be equal to or greater than BITS_PER_TYPE(u32) as we do bitwise AND with a u32 variable and BIT(chiprev). The patch adds a check that makes the function return NULL if that is the case. Note that the NULL case is later handled by the bus-specific caller, brcmf_usb_probe_cb() or brcmf_usb_reset_resume(), for example. Found by a modified version of syzkaller.

2022-11-04macsec: fix detection of RXSCs when toggling offloadingSabrina Dubroca
macsec_is_configured incorrectly uses secy->n_rx_sc to check if some RXSCs exist. secy->n_rx_sc only counts the number of active RXSCs, but there can also be inactive SCs as well, which may be stored in the driver (in case we're disabling offloading), or would have to be pushed to the device (in case we're trying to enable offloading). As long as RXSCs active on creation and never turned off, the issue is not visible.

2022-11-04macsec: fix secy->n_rx_sc accountingSabrina Dubroca
secy->n_rx_sc is supposed to be the number of _active_ rxsc's within a secy. This is then used by macsec_send_sci to help decide if we should add the SCI to the header or not. This logic is currently broken when we create a new RXSC and turn it off at creation, as create_rx_sc always sets ->active to true (and immediately uses that to increment n_rx_sc), and only later macsec_add_rxsc sets rx_sc->active.

2022-11-04Revert "net: macsec: report real_dev features when HW offloading is enabled"Sabrina Dubroca
This reverts commit c850240b6c4132574a00f2da439277ab94265b66. That commit tried to improve the performance of macsec offload by taking advantage of some of the NIC's features, but in doing so, broke macsec offload when the lower device supports both macsec and ipsec offload, as the ipsec offload feature flags (mainly NETIF_F_HW_ESP) were copied from the real device. Since the macsec device doesn't provide xdo_* ops, the XFRM core rejects the registration of the new macsec device in xfrm_api_check. Example perf trace when running ip link add link eni1np1 type macsec port 4 offload mac ip 737 [003] 795.477676: probe:xfrm_dev_event__REGISTER name="macsec0" features=0x1c000080014869 xfrm_dev_event+0x3a notifier_call_chain+0x47 register_netdevice+0x846 macsec_newlink+0x25a ip 737 [003] 795.477687: probe:xfrm_dev_event__return ret=0x8002 (NOTIFY_BAD) notifier_call_chain+0x47 register_netdevice+0x846 macsec_newlink+0x25a dev->features includes NETIF_F_HW_ESP (0x04000000000000), so xfrm_api_check returns NOTIFY_BAD because we don't have dev->xfrmdev_ops on the macsec device. We could probably propagate GSO and a few other features from the lower device, similar to macvlan. This will be done in a future patch.

Replace the 32-bit unsigned used to track endpoints that have completed setup with a Linux bitmap, to allow an arbitrary number of endpoints to be represented. Rework the error handling in ipa_endpoint_init() so the defined endpoint bitmap is freed if an error occurs early. Once endpoints have been initialized, ipa_endpoint_exit() is used to recover if the set of filtered endpoints is invalid. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2022-11-04net: ipa: support more filtering endpointsAlex Elder
Prior to IPA v5.0, there could be no more than 32 endpoints. A filter table begins with a bitmap indicating which endpoints have a filter defined. That bitmap is currently assumed to fit in a 32-bit value. Starting with IPA v5.0, more than 32 endpoints are supported, so it's conceivable that a TX endpoint has an ID that exceeds 32. Increase the size of the field representing endpoints that support filtering to 64 bits. Rename the bitmap field "filtered". Unlike other similar fields, we do not use an (arbitrarily long) Linux bitmap for this purpose. The reason is that if a filter table ever *did* need to support more than 64 TX endpoints, its format would change in ways we can't anticipate. Have ipa_endpoint_init() return a negative errno rather than a mask that indicates which endpoints support filtering, and have that function assign the "filtered" field directly.

2022-11-04net: ipa: use a bitmap for defined endpointsAlex Elder
IPA v5.0 supports more than 32 endpoints, so we will be unable to represent endpoints defined in the configuration data with a 32-bit value. To prepare for that, convert the field in the IPA structure representing defined endpoints to be a Linux bitmap. Convert loops based on that field into for_each_set_bit() calls over the new bitmap. Note that the loop in ipa_endpoint_config() still assumes there are 32 or fewer endpoints (when comparing against the available endpoint bit mask); that assumption goes away in the next patch.

2022-11-04net: ipa: add a parameter to suspend registersAlex Elder

2022-11-04net: ipa: add a parameter to aggregation registersAlex Elder
Starting with IPA v5.0, a single IPA instance can have more than 32 endpoints defined. To handle this, each register that holds a bitmap of IPA endpoints is replicated as needed to represent the available endpoints. To prepare for this, registers that represent endpoint IDs in a bit mask will be defined to have a parameter, with a stride value of 4 bytes. The first 32 endpoints are represented in the first 32-bit register, then the next (up to) 32 endpoints at an offset 4 bytes higher. When accessing such a register, the endpoint ID divided by 32 determines the offset, and the endpoint ID modulo 32 defines the endpoint's bit position within the register. The first two registers we'll update for this are STATE_AGGR_ACTIVE and AGGR_FORCE_CLOSE. Until more than 32 endpoints are supported, this change has no practical effect.

2022-11-04net: ipa: reduce arguments to ipa_table_init_add()Alex Elder
Recently ipa_table_mem() was added as a way to look up one of 8 possible memory regions by indicating whether it was a filter or route table, hashed or not, and IPv6 or not. We can simplify the interface to ipa_table_init_add() by passing two flags to it instead of the opcode and both hashed and non-hashed memory region IDs. The "filter" and "ipv6" flags are sufficient to determine the opcode to use, and with ipa_table_mem() can look up the correct memory region as well. It's possible to not have hashed tables, but we already verify the number of entries in a filter or routing table is nonzero. Stop assuming a hashed table entry exists in ipa_table_init_add().
