2022-10-21wifi: rt2x00: use explicitly signed or unsigned typesJason A. Donenfeld13-58/+58
On some platforms, `char` is unsigned, but this driver, for the most part, assumed it was signed. In other places, it uses `char` to mean an unsigned number, but only in cases when the values are small. And in still other places, `char` is used as a boolean. Put an end to this confusion by declaring explicit types, depending on the context.

2022-09-19wifi: rt2x00: Fix "Error - Attempt to send packet over invalid queue 2"Hans de Goede1-1/+4
Even though ieee80211_hw.queues is set to 2, the ralink rt2x00 driver is seeing tx skbs submitted to it with the queue-id set to 2 / set to IEEE80211_AC_BE on a rt2500 card when associating with an access-point. This causes rt2x00queue_get_tx_queue() to return NULL and the following error to be logged: "ieee80211 phy0: rt2x00mac_tx: Error - Attempt to send packet over invalid queue 2", after which association with the AP fails. This patch works around this by mapping QID_AC_BE and QID_AC_BK to QID_AC_VI when there are only 2 tx_queues.

The third argument of usb_maxpacket(): in_out has been deprecated because it could be derived from the second argument (e.g. using usb_pipeout(pipe)). N.B. function usb_maxpacket() was made variadic to accommodate the transition from the old prototype with three arguments to the new one with only two arguments (so that no renaming is needed). The variadic argument is to be removed once all users of usb_maxpacket() get migrated. CC: Oliver Neukum <oliver@neukum.org> CC: David S.

2022-04-11mac80211: prepare sta handling for MLO supportSriram R2-5/+5
Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2021-04-13of: net: pass the dst buffer to of_get_mac_address()Michael Walle1-5/+1
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

2020-08-02rt2x00: pci: use generic power managementVaibhav Gupta10-46/+19
Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. The callbacks make use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device() and pci_set_power_state() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use dev_get_drvdata() to get drv data. The .suspend() callback is invoking rt2x00lib_suspend() which needs to be modified as generic rt2x00pci_suspend() has no pm_message_t type argument, passed to it, which is required by it according to its declaration. Although this variable remained unused in the function body. Hence, remove it from the function definition & declaration. rt2x00lib_suspend() is also invoked by rt2x00usb_suspend() and rt2x00soc_suspend(). Thus, modify the functional call accordingly in their function body. Earlier, .suspend() & .resume() were exported and were used by the following drivers: - drivers/net/wireless/ralink/rt2x00/rt2400pci.c - drivers/net/wireless/ralink/rt2x00/rt2500pci.c - drivers/net/wireless/ralink/rt2x00/rt2800pci.c - drivers/net/wireless/ralink/rt2x00/rt61pci.c Now, we only need to bind "struct dev_pm_ops" variable to "struct pci_driver". Thus, make the callbacks static. Declare an "extern const struct dev_pm_ops" variable and bind PM callbacks to it. Now, export the variable instead and use it in respective drivers. Compile-tested only.
