We don't have to check bSurpriseRemoved in the SwLedOn function. SwLedOn calls rtw_read8 which in turn calls usb_read. This function checks bSurpriseRemoved for us. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

Both bLedOn and BlinkingLedState in struct led_priv store the same information. The boolean bLedOn stores the curent led state while BlinkingLedState stores the next led state to be set during blinking, which is the inverse of the current led state. (The led is either off or blinking, it's never continuously on.) This patch removes BlinkingLedState and uses bLedOn instead. The LED_BLINK_WPS_STOP case in blink_work checked for pLed->BlinkingLedState != RTW_LED_ON. This is true if the next led blinking state is ON, i.e. if the led has just been switched off by blink_work, i.e. if (!pLed->bLedOn).

Remove the bLedNoLinkBlinkInProgress state variable. Its sole purpose is to block subsequent requests for "no link" blinking when this blinking pattern is already active. It's perfectly safe to restart "no link" blinking. We can remove bLedNoLinkBlinkInProgress and the many places where it's updated.

The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev). The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of rtw_xmit_entry should be changed from int to netdev_tx_t. Link: https://github.com/ClangBuiltLinux/linux/issues/1703 Cc: llvm@lists.linux.dev Reported-by:

In _rtw_init_xmit_priv(), there are several error paths for allocation failures just jump to the `exit` section. However, there is no action will be performed, so the allocated resources are not properly released, which leads to various memory leaks. To properly release them, this patch unifies the error handling code and several error handling paths are added. According to the allocation sequence, if the validation fails, it will jump to its corresponding error tag to release the resources.

In rtw_xmit_resource_alloc(), if usb_alloc_urb() fails, then the memory `pxmitbuf->pallocated_buf` which is allocated by kzalloc() is not properly released before returning. So this patch adds kfree() on the above error path to release it in time. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Reviewed-by:

The functions _rtw_init_recv_priv(), _rtw_free_recv_priv() and rtw_recv_entry() are defined in rtw_recv.c. Move their prototypes from recv_osdep.h to rtw_recv.h. Move the last two remaining prototypes netdev_open() and netdev_close() from recv_osdep.h to osdep_intf.h. That is a more appropriate place and we can remove recv_osdep.h.

In rtw_init_cmd_priv(), if `pcmdpriv->rsp_allocated_buf` is allocated in failure, then `pcmdpriv->cmd_allocated_buf` will not be properly released. Besides, considering there are only two error paths and the first one can directly return, we do not need to implicitly jump to the `exit` tag to execute the error handling code. So this patch added `kfree(pcmdpriv->cmd_allocated_buf);` on the error path to release the resource and simplified the return logic of rtw_init_cmd_priv(). As there is no proper device to test with, no runtime testing was performed. Tested-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> # Edimax N150 Signed-off-by:

In some initialization functions of this driver, memory is allocated with 'i' acting as an index variable and increasing from 0. The commit in "Fixes" introduces some clean-up codes in case of allocation failure, which free memory in reverse order with 'i' decreasing to 0. However, there are some problems: - The case i=0 is left out. Thus memory is leaked. - In case memory allocation fails right from the start, the memory freeing loops will start with i=-1 and invalid memory locations will be accessed. One of these loops has been fixed in commit c8ff9153 ("staging: vt6655: fix potential memory leak"). Fix the remaining erroneous loops.

In rtw_init_drv_sw(), there are various init functions are called to populate the padapter structure and some checks for their return value. However, except for the first one error path, the other five error paths do not properly release the previous allocated resources, which leads to various memory leaks. This patch fixes them and keeps the success and error separate. Note that these changes keep the form of `rtw_init_drv_sw()` in "drivers/staging/r8188eu/os_dep/os_intfs.c". As there is no proper device to test with, no runtime testing was performed. Signed-off-by:
