2024-03-04wifi: mac80211: add ieee80211_vif_link_active() helperJohannes Berg5-15/+23
We sometimes need to check if a link is active, and this is complicated by the fact that active_links has no bits set when the vif isn't (acting as) an MLD. Add a small new helper ieee80211_vif_link_active() to make that a bit easier, and use it in a few places.

2024-03-04wifi: mac80211: Adjust CQM handling for MLOIlan Peer1-29/+50
The CQM handling did not consider the MLO case and thus notified a not-existing link with the CQM change. To fix this, propagate the CQM notification to all the active links (handling both the non-MLO and MLO cases). TODO: this currently propagates the same configuration to all links regardless of the band. This might not be the correct approach as different links might need to be configured with different values.

In the association request, we make some parameters depend on the AP's HT/VHT information. This was broken by my code because it no longer filled that information, making it all zero.

2024-03-04wifi: mac80211: handle netif carrier up/down with link AP during MLOAditya Kumar Singh1-2/+30
Currently whenever link AP is started, netif_carrier_up() function is called and whenever it is brought down, netif_carrier_down() function is called. However, with MLO, all the links of the same MLD would use the same netdev. Hence there is no need to indicate for each link up/down. Also, calling it down when only one of the links went down is not desirable. Add changes to call the netif_carrier_up() function only when first link is brought up. Similarly, add changes to call the netif_carrier_down() function only when last link is brought down. In order to check the number of beaconing links in the given interface, introduce a new helper function ieee80211_num_beaconing_links().

2024-03-04wifi: mac80211: track capability/opmode NSS separatelyJohannes Berg5-28/+30
We're currently tracking rx_nss for each station, and that is meant to be initialized to the capability NSS and later reduced by the operating mode notification NSS. However, we're mixing up capabilities and operating mode NSS in the same variable. This forces us to recalculate the NSS capability on operating mode notification RX, which is a bit strange; due to the previous fix I had to never keep rx_nss as zero, it also means that the capa is never taken into account properly. Fix all this by storing the capability value, that can be recalculated unconditionally whenever needed, and storing the operating mode notification NSS separately, taking it into account when assigning the final rx_nss value.

2024-02-28bitfield: suppress "dubious: x & !y" sparse warningJohannes Berg1-1/+2
There's a somewhat common pattern of using FIELD_PREP() even for single bits, e.g. cmd->info1 |= FIELD_PREP(HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP, !!(params.flags & HAL_SRNG_FLAGS_MSI_SWAP)); which might as well be written as if (params.flags & HAL_SRNG_FLAGS_MSI_SWAP) cmd->info1 |= HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP; (since info1 is fully initialized to start with), but in a long chain of FIELD_PREP() this really seems fine. However, it triggers a sparse warning, in the check in the macro for whether a constant value fits into the mask, as this contains a "& (_val)". In this case, this really is always intentional, so just suppress the warning by adding "0+" to the expression, indicating explicitly that this is correct.

2024-02-27wifi: brcmfmac: fweh: Fix boot crash on Raspberry Pi 4Gustavo A. R. Silva1-1/+1
Fix boot crash on Raspberry Pi by moving the update to `event->datalen` before data is copied into flexible-array member `data` via `memcpy()`. Flexible-array member `data` was annotated with `__counted_by(datalen)` in commit 62d19b358088 ("wifi: brcmfmac: fweh: Add __counted_by for struct brcmf_fweh_queue_item and use struct_size()"). The intention of this is to gain visibility into the size of `data` at run-time through its _counter_ (in this case `datalen`), and with this have its accesses bounds-checked at run-time via CONFIG_FORTIFY_SOURCE and CONFIG_UBSAN_BOUNDS. To effectively accomplish the above, we shall update the counter (`datalen`), before the first access to the flexible array (`data`), which was also done in the mentioned commit. However, commit edec42821911 ("wifi: brcmfmac: allow per-vendor event handling") inadvertently caused a buffer overflow, detected by FORTIFY_SOURCE. It moved the `event->datalen = datalen;` update to after the first `data` access, at which point `event->datalen` was not yet updated from zero (after calling `kzalloc()`), leading to the overflow issue. This fix repositions the `event->datalen = datalen;` update before accessing `data`, restoring the intended buffer overflow protection. :) Fixes: edec42821911 ("wifi: brcmfmac: allow per-vendor event handling") Reported-by: Nathan Chancellor <nathan@kernel.org> Closes: https://gist.github.com/nathanchance/e22f681f3bfc467f15cdf6605021aaa6 Tested-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Gustavo A.

Through the routine bond_mii_monitor(), bonding driver inspects and commits the slave state changes. During the times when slave state change and failure in aqcuiring rtnl lock happen at the same time, the routine bond_mii_monitor() reschedules itself to come around after 1 msec to commit the new state. During this, it executes the routine bond_miimon_inspect() to re-inspect the state chane and prints the corresponding slave state on to the console. Hence we do see a message at every 1 msec till the rtnl lock is acquired and state chage is committed. This patch doesn't change how bond functions. It only simply limits this kind of log flood.

2024-02-23ipv6/sit: Do not allocate stats in the driverBreno Leitao1-8/+4
With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now. Remove the allocation in the ipv6/sit driver and leverage the network core allocation.

It was masked out to 0xfffff. With the new code that allows the user to change the size of the sub-buffer, it is theoretically possible to ask for a size bigger than 2^20. If that happens, unexpected results may occur as there's no code checking if the counter overflowed the 20 bits of the write mask. There are other checks to make sure events fit in the sub-buffer, but if the sub-buffer itself is too big, that is not checked. Add a check in the resize of the sub-buffer to make sure that it never goes beyond the size of the counter that holds how much data is on it. * tag 'trace-v6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Do not let subbuf be bigger than write mask

Michael Chan says: ==================== bnxt_en: Ntuple filter improvements The current Ntuple filter implementation has a limitation on 5750X (P5) and newer chips. The destination ring of the ntuple filter must be a valid ring in the RSS indirection table. Ntuple filters may not work if the RSS indirection table is modified by the user to only contain a subset of the rings. If an ntuple filter is set to a ring destination that is not in the RSS indirection table, the packet matching that filter will be placed in a random ring instead of the specified destination ring. This series of patches will fix the problem by using a separate VNIC for ntuple filters. The default VNIC will be dedicated for RSS and so the indirection table can be setup in any way and will not affect ntuple filters using the separate VNIC. Quite a bit of refactoring is needed to do the the VNIC and RSS context accounting in the first few patches. This is technically a bug fix, but I think the changes are too big for -net. ==================== Link: https://lore.kernel.org/r/20240220230317.96341-1-michael.chan@broadcom.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Even though this VNIC is only used for ntuple filters with direct ring destinations, we still setup the RSS hash to be identical to the default VNIC so that each RX packet will have the correct hash in the RX completion.

2024-02-22bnxt_en: Provision for an additional VNIC for ntuple filtersPavan Chebbi2-5/+32
On newer chips that support the ring table index method for ntuple filters, the current scheme of using the same VNIC for both RSS and ntuple filters will not work in all cases. An ntuple filter can only be directed to a destination ring if that destination ring is also in the RSS indirection table. To support ntuple filters with any arbitratry RSS indirection table that may only include a subset of the rings, we need to use a separate VNIC for ntuple filters. This patch provisions the additional VNIC. The next patch will allocate additional VNIC from firmware and set it up.
