2024-01-26wifi: iwlwifi: remove retry loops in startJohannes Berg3-31/+10
There's either the pldr_sync case, in which case we didn't want or do the retry loops anyway, or things will just continue to fail. Remove the retry loop that was added in a previous attempt to address the issue that was later (though still a bit broken) addressed by the pldr_sync case.

2024-01-26wifi: iwlwifi: mvm: limit EHT 320 MHz MCS for STEP URMJohannes Berg4-1/+16
If the STEP (the interface between MAC and PHY) is in URM (a lower speed mode) then we cannot use 320 MHz MCS > 9. Therefore, limit the MCS in our capabilities in this case. Note that this also limits the TX/rate scaling since that takes both TX and RX capabilities into account.

2024-01-23wifi: iwlegacy: Use kcalloc() instead of kzalloc()Erick Archer1-3/+1
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function. Also, it is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter).

eSR is activated when a chanctx is assigned to more than one link. During eSR activation we should disable RLC for both phys, and configure the FW with a special phy command for both phys. Currently we assign the phy_ctxt to the link only after eSR activation, so RLC is not disabled for the new phy_ctxt, and a cmd is not sent to FW.

2023-12-12wifi: iwlwifi: remove async command callbackJohannes Berg8-82/+39
There's only one user of this code, which is STA unblock during sleep for uAPSD on really old devices. Instead of having this all through the API with calls up and down, just implemented a special-case CMD_BLOCK_TXQS flag for this, it's only needed in the old gen1 transport. While at it, fix a complain that lockdep would have, as we lock the cmd queue and then the TXQs in the reclaim by using spin_lock_nested(). We no longer need to disable BHs in iwl_trans_pcie_block_txq_ptrs() since it's called with them disabled already.

2023-12-12wifi: iwlwifi: refactor RX tracingJohannes Berg5-27/+46
When there's not going to be any data in the data event, we don't need to add it at all (unlike the TX version, it has no data at all.) Also combine the tracing into a separate inline so we only call iwl_rx_trace_len() once, which also simplifies things, and lets us have a single place to later add other checks.

2023-12-01wifi: iwlwifi: fw: replace deprecated strncpy with strscpy_padJustin Stitt1-4/+4
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. Based on the deliberate `sizeof(dest) ... - 1` pattern we can see that both dump_info->dev_human_readable and dump_info->bus_human_readable are intended to be NUL-terminated. Moreover, since this seems to cross the file boundary let's NUL-pad to ensure no behavior change. strscpy_pad() covers both the NUL-termination and NUL-padding, let's use it.
