In FW restart scenarios, we allocate the queues from the iwl_mvm_realloc_queues_after_restart() function, but that is called before we insert the station ID into our map (mvm->fw_id_to_mac_id). However, in all cases where we're actually allocating a queue for a "real" (not bcast, aux, ...) station we have the sta pointer already, so just pass it along to use it instead of looking it up. This fixes an issue where after restart we only allocated a queue of size 16 (due to the ordering issue described above), and thus never got good throughput again since no aggregates could be formed on transmit.

Commit f79cbc77 ("wifi: move mac80211_hwsim and virt_wifi to virtual directory") and commit 298e50ad ("wifi: move raycs, wl3501 and rndis_wlan to legacy directory") move remaining wireless drivers into subdirectories, but does not adjust the entries in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about broken references. Repair these file references in those wireless driver sections. Signed-off-by:

Fix a slab-out-of-bounds read that occurs in kmemdup() called from brcmf_get_assoc_ies(). The bug could occur when assoc_info->req_len, data from a URB provided by a USB device, is bigger than the size of buffer which is defined as WL_EXTRA_BUF_MAX. Add the size check for req_len/resp_len of assoc_info. Found by a modified version of syzkaller.

Replace the calculations for the payload length in qtnf_cmd_band_fill_iftype with struct_size() and size_sub(). While the payload length does not get directly passed to an allocation function, the performed calculation is still calculating the size of a flexible array structure (minus the size of a header structure).

The ipw_fw_error structure contains a payload[] flexible array as well as two pointers to this array area, ->elem, and ->log. The total size of the allocated structure is computed without use of the <linux/overflow.h> macros. There's no reason to keep both a payload[] and an extra pointer to both the elem and log members. Convert the elem pointer member into the flexible array member, removing payload. Fix the allocation of the ipw_fw_error structure to use size_add(), struct_size(), and array_size() to compute the allocation. This ensures that any overflow saturates at SIZE_MAX rather than overflowing and potentially allowing an undersized allocation. Before the structure change, the layout of ipw_fw_error was: struct ipw_fw_error { long unsigned int jiffies; /* 0 8 */ u32 status; /* 8 4 */ u32 config; /* 12 4 */ u32 elem_len; /* 16 4 */ u32 log_len; /* 20 4 */ struct ipw_error_elem * elem; /* 24 8 */ struct ipw_event * log; /* 32 8 */ u8 payload[]; /* 40 0 */ /* size: 40, cachelines: 1, members: 8 */ /* last cacheline: 40 bytes */ }; After this change, the layout is now: struct ipw_fw_error { long unsigned int jiffies; /* 0 8 */ u32 status; /* 8 4 */ u32 config; /* 12 4 */ u32 elem_len; /* 16 4 */ u32 log_len; /* 20 4 */ struct ipw_event * log; /* 24 8 */ struct ipw_error_elem elem[]; /* 32 0 */ /* size: 32, cachelines: 1, members: 7 */ /* last cacheline: 32 bytes */ }; This saves a total of 8 bytes for every ipw_fw_error allocation, and removes the risk of a potential overflow on the allocation.

Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are all special world-wide compatibility ccode-s. Most of these world-wide ccode-s allow passive scan mode only for 2.4GHz channels 12-14, only enabling them when an AP is seen on them. Since linux-firmware has moved to the new cyfmac4356-pci.bin + cyfmac4356-pci.clm_blob firmware files this no longer works and 4356 devices using e.g. an X2 ccode fail to connect to an AP on channel 13. Add the 4356 chip-id to the list of chips for which to use the ISO3166 country code + rev 0 as fallback in brcmf_translate_country_code() to fix this. Signed-off-by:

To clean up drivers/net/wireless move the old drivers drivers left in the directory to a new "legacy" directory. I did consider adding CONFIG_WLAN_VENDOR_LEGACY like other vendors have but then dropped the idea as these are really old drivers and hopefully we get to remove them soon. There should be no changes in compilation or in Kconfig options, merely moving files. Signed-off-by:

The bindings for the am65-cpsw driver use the name "serdes" to refer to the Serdes PHY. Thus, update the name used for the Serdes PHY within the am65_cpsw_init_serdes_phy() function from "serdes-phy" to "serdes". Signed-off-by:

Update bindings to include Serdes PHY as an optional PHY, in addition to the existing CPSW MAC's PHY. The CPSW MAC's PHY is required while the Serdes PHY is optional. The Serdes PHY handle has to be provided only when the Serdes is being configured in a Single-Link protocol. Using the name "serdes-phy" to represent the Serdes PHY handle, the am65-cpsw-nuss driver can obtain the Serdes PHY and request the Serdes to be configured. Signed-off-by:

Russell King says: ==================== Rework SFP A2 access conditionals This series reworks the SFP A2 (diagnostics and control) access so we don't end up testing a variable number of conditions in several places. This also resolves a minor issue where we may have a module indicating that it is not SFF8472 compliant, doesn't implement A2, but fails to set the enhanced option byte to zero, leading to accesses to the A2 page that fail. The first patch adds a new flag "have_a2" which indicates whether we should be accessing the A2 page, and uses this for hwmon. The conditions are kept the same. The second patch extends the check for soft-state polling and control by using this "have_a2" flag (which effectively augments the check to include some level of SFF8472 compliance.) ==================== Link: https://lore.kernel.org/r/ZAoBnqGBnIZzLwpV@shell.armlinux.org.ukSigned-off-by:

The soft state bits are stored in the A2h memory space, and require SFF-8472 compliance. This is what our have_a2 flag tells us, so use this to indicate whether we should attempt to use the soft signals. Signed-off-by:

The hwmon code wants to know when it is safe to access the A2h data stored in a separate address. We indicate that this is present when we have SFF-8472 compliance and the lack of an address-change sequence., The same conditions are also true if we want to access other controls and status in the A2h address. So let's make a flag to indicate whether we can access it, instead of repeating the conditions throughout the code. For now, only convert the hwmon code. Signed-off-by:
