* [PATCH 14/17] mt7615: mcu: use standard signature for mt7615_mcu_msg_send
From: Lorenzo Bianconi @ 2019-05-04 15:29 UTC (permalink / raw)
To: nbd; +Cc: lorenzo.bianconi, linux-wireless, ryder.lee, royluo
In-Reply-To: <cover.1556981521.git.lorenzo@kernel.org>
Use mt76 common signature for mt7615_mcu_msg_send. Move skb allocation
in mt7615_mcu_msg_send and remove duplicated code. Remove
__mt7615_mcu_set_wtbl and __mt7615_mcu_set_sta_rec since now are used
just to send mcu msgs. This is a preliminary patch for mt7615-mt7603 mcu
code unification

* [PATCH 12/17] mt7615: mcu: do not use function pointers whenever possible
From: Lorenzo Bianconi @ 2019-05-04 15:29 UTC (permalink / raw)
To: nbd; +Cc: lorenzo.bianconi, linux-wireless, ryder.lee, royluo
In-Reply-To: <cover.1556981521.git.lorenzo@kernel.org>
Remove function pointers in mt7615_mcu_set_bss_info and run function
directly. Moreover remove __mt7615_mcu_set_bss_info since it is run just
by mt7615_mcu_set_bss_info and remove duplicated istructions

In-Reply-To: <cover.1556981521.git.lorenzo@kernel.org>
Remove skb_ret parameter from mt7615_mcu_msg_send signature since it is
actually used just by mt7615_mcu_patch_sem_ctrl. This is a prelimanry
patch to use mt76 common mcu API

* [PATCH 03/17] mt7615: mcu: remove bss_info_convert_vif_type routine
From: Lorenzo Bianconi @ 2019-05-04 15:28 UTC (permalink / raw)
To: nbd; +Cc: lorenzo.bianconi, linux-wireless, ryder.lee, royluo
In-Reply-To: <cover.1556981521.git.lorenzo@kernel.org>
Remove bss_info_convert_vif_type routine since it is run just in
mt7615_mcu_set_bss_info and the switch over vif->type is already there.
Simplify mt7615_mcu_set_bss_info routine

From: Lorenzo Bianconi @ 2019-05-04 15:28 UTC (permalink / raw)
To: nbd; +Cc: lorenzo.bianconi, linux-wireless, ryder.lee, royluo
Introduce mt76_mcu_ops data structure in mt7615 mcu code in order
to reuse the code with other bus types and unify the code with mt7603
driver
Changes since RFC:
- rebase ontop of https://patchwork.kernel.org/patch/10928753/
- fix net_type initialization in mt7615_mcu_set_bss_info

mt7615: mcu: simplify __mt7615_mcu_set_sta_rec
mt7615: mcu: remove bss_info_convert_vif_type routine
mt7615: mcu: use proper msg size in mt7615_mcu_add_wtbl_bmc
mt7615: mcu: use proper msg size in mt7615_mcu_add_wtbl
mt7615: mcu: unify mt7615_mcu_add_wtbl_bmc and mt7615_mcu_del_wtbl_bmc
mt7615: mcu: remove unused parameter in mt7615_mcu_del_wtbl
mt7615: remove query from mt7615_mcu_msg_send signature
mt7615: remove dest from mt7615_mcu_msg_send signature
mt7615: mcu: remove skb_ret from mt7615_mcu_msg_send
mt7615: mcu: unify __mt7615_mcu_set_dev_info and

Such mechanical patches w/o understanding the code are always
problematic. Do you have any proof that this error is fatal?
I think it is not, else we wouldn't have this line:
ah->reset_power_on = false;
Also you should consider that a mutex and a spinlock are held.
Maybe changing the error message to a warning would be more
appropriate. But this I would leave to somebody being more
familiar with this driver.

* [PATCH] net: wireless: iwlwifi: Fix double-free problems in iwl_req_fw_callback()

To: johannes.berg, emmanuel.grumbach, luciano.coelho, linuxwifi,
kvalo, davem
Cc: linux-wireless, netdev, linux-kernel, Jia-Ju Bai
In the error handling code of iwl_req_fw_callback(), iwl_dealloc_ucode()
is called to free data. In iwl_drv_stop(), iwl_dealloc_ucode() is called
again, which can cause double-free problems.
To fix this bug, the call to iwl_dealloc_ucode() in
iwl_req_fw_callback() is deleted.
This bug is found by a runtime fuzzing tool named FIZZER written by us.

^^^^^^^^^^^^^^^^^^^^^^^^^^
This is a false positive because we know that "log_idx + 1" is an odd
number and logical_size is even so they can't be equal... But I wonder
if it would make it more readable to change the > to >=?
The log_map[] array has logical_size elements. It's allocated in
rtw_parse_efuse_map().
75 return -EINVAL;
76
77 log_map[log_idx] = phy_map[phy_idx];
78 log_map[log_idx + 1] = phy_map[phy_idx + 1];
^^^^^^^^^^^^^^^^^^^

Wen,
5468e784c0600551ca03263f5255a375c05f88e7 commit message gives reasons
for adding the mmc_hw_reset() call. The commit message for removing
gives different reason for removal. Both are good but second one is
incomplete.
The commit message for removal should ALSO explain why adding this
call wasn't necessary in the first place OR move the call to a
different code path.
> Remove mmc_hw_reset will avoid the drop of clock.
This commit message makes it clear the original patch introduced a new
problem. But the original patch fixed a different problem and that
this proposed change seems likely to re-introduce and the commit
message should explain why that isn't true (or how the original was
fixed differently)
cheers,
