For multi-link operation(MLO) TDLS management frames need to be transmitted on a specific link. The TDLS setup request will add BSSID along with peer address and userspace will pass the link-id based on BSSID value to the driver(or mac80211). Signed-off-by:

-Wstringop-overflow is legitimately warning us about extra_size pontentially being zero at some point, hence potenially ending up _allocating_ zero bytes of memory for extra pointer and then trying to access such object in a call to copy_from_user(). Fix this by adding a sanity check to ensure we never end up trying to allocate zero bytes of data for extra pointer, before continue executing the rest of the code in the function. Address the following -Wstringop-overflow warning seen when built m68k architecture with allyesconfig configuration: from net/wireless/wext-core.c:11: In function '_copy_from_user', inlined from 'copy_from_user' at include/linux/uaccess.h:183:7, inlined from 'ioctl_standard_iw_point' at net/wireless/wext-core.c:825:7: arch/m68k/include/asm/string.h:48:25: warning: '__builtin_memset' writing 1 or more bytes into a region of size 0 overflows the destination [-Wstringop-overflow=] 48 | #define memset(d, c, n) __builtin_memset(d, c, n) | ^~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/uaccess.h:153:17: note: in expansion of macro 'memset' 153 | memset(to + (n - res), 0, res); | ^~~~~~ In function 'kmalloc', inlined from 'kzalloc' at include/linux/slab.h:694:9, inlined from 'ioctl_standard_iw_point' at net/wireless/wext-core.c:819:10: include/linux/slab.h:577:16: note: at offset 1 into destination object of size 0 allocated by '__kmalloc' 577 | return __kmalloc(size, flags); | ^~~~~~~~~~~~~~~~~~~~~~ This help with the ongoing efforts to globally enable -Wstringop-overflow.

The max active links that are supported by the FW is hard coded. This is wrong since this value is HW-dependent. Fix this by determining according to the actual HW. Also remove a redundant check that the number of active links doesn't exceeds the maximum. Signed-off-by:

In mesh mode, ieee80211_chandef_he_6ghz_oper() is called by mesh_matches_local() for every received mesh beacon. On a 6 GHz mesh of a HE-only phy, this spams that the hardware does not have EHT capabilities, even if the received mesh beacon does not have an EHT element. Unlike HE, not supporting EHT in the 6 GHz band is not an error so do not print anything in this case. Fixes: 5dca295d ("mac80211: Add initial support for EHT and 320 MHz channels") Signed-off-by:

We skipped this in the past, but now we will need it for some platforms. Implement loading the PHY filter configuration IDs from the WPFC ACPI table. Note that the firmware must also be aware of the right filter configuration IDs (they're just the IDs of a filter configuration, not the actual configuration). Remove the useless hardcoded zeroes while at it. Signed-off-by:

rxq can be NULL only when trans_pcie->rxq is NULL and entry->entry is zero. For the case when entry->entry is not equal to 0, rxq won't be NULL even if trans_pcie->rxq is NULL.

When the firmware misbehaves (according to the driver), we often either ignore that, or WARN_ON, which is very noisy but doesn't really help. Add a little helper macro IWL_FW_CHECK() that can be used in place of WARN_ON() in conditions, and make it take a message that's printed in this case. We can also add more behaviour to this in the future. Signed-off-by:

Again, during some (botched) FW restart scenarios we can end up with a NULL link in the driver but mac80211 thinking all is still going OK. If we try to TX at the same time, we can crash there. Fix that by checking for a NULL link during TX. Signed-off-by:

We've observed that in some botched firmware restart scenarios when the firmware crashes again while we're reconfiguring, we can hit NULL pointer crashes here. The underlying issue is the botched restart which we need to fix separately, but until we can do that, don't crash hard here. Signed-off-by:

In mac80211, it's required that we pull from TXQs by calling ieee80211_tx_dequeue() only with softirqs disabled. However, in iwl_mvm_queue_state_change() we're often called with them enabled, e.g. from flush if anything was flushed, triggering a mac80211 warning. Fix that by disabling the softirqs across the TX call. Fixes: cfbc6c4c ("iwlwifi: mvm: support mac80211 TXQs model") Signed-off-by:

We can't just dereference the sband->iftype_data pointer, that's an array so we need to access the right entry. Use the previously introduced helper functions to do that. There are also cases, e.g. when loading with disable_11ax=1, where the pointer might be NULL but we still attempt to use it, causing a crash.

GCC 12.2 with W=1 warns: drivers/net/wireless/legacy/ray_cs.c:630:17: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] The driver uses SSID as a string which is just wrong, it should be treated as a byte array instead. But as the driver is ancient and most likely there are no users so convert it to use strscpy(). This makes sure that the string is NUL-terminated and also the warning is fixed. Signed-off-by:

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since DEV_ASSIGN is only used by TRACE macros and the return values are ignored.
