The HCI User Channel is an admin operation which enforces CAP_NET_ADMIN when binding the socket. Problem now is that it then requires also CAP_NET_RAW when calling into hci_sock_sendmsg. This is not intended and just an oversight since general HCI sockets (which do not require special permission to bind) and HCI User Channel share the same code path here. Remove the extra CAP_NET_RAW check for HCI User Channel write operation since the permission check has already been enforced when binding the socket. This also makes it possible to open HCI User Channel from a privileged process and then hand the file descriptor to an unprivilged process. Signed-off-by:

This driver uses a number of macros to get and set various fields in the RX and TX descriptors. To work correctly, a u8 pointer to the descriptor must be used; however, in some cases a descriptor structure pointer is used instead. In addition, a duplicated statement is removed. Signed-off-by:

1) After driver load failure, clear 'card->adapter' instead of card pointer so that card specific cleanup is performed later when user unloads the driver. 2) Clear usb_card pointer in disconnect handler to avoid invalid memory access when user unloads the driver after removing the card.

When driver is failed to load, card pointer doesn't get freed. We will free it in cleanup handler which is called in failure as well as unload path. Also, update drvdata in init/cleanup handlers instead of register/unregister handlers. Signed-off-by:

1) Currently we freeing wdev for each interface in driver unload path. We may leak memory if user have already deleted an interface. mwifiex_add_virtual_intf() allocates wdev structure. So it should be freed in mwifiex_del_virtual_intf(). This will make sure that wdev will be freed when user deletes an interface and also in unload path. 2) "priv->netdev->ieee80211_ptr" should also be cleared in mwifiex_del_virtual_intf. Signed-off-by:

We don't need to free/unregister wiphy when mwifiex_register_cfg80211() fails. The routine internally takes care of it. This redundant code can cause NULL pointer dereference, for adapter->wiphy. Reported-by:

1) If register_netdevice() is failed, we are freeing netdev pointer, but priv->netdev is not cleared. This gives kernel paging request error when driver is unloaded or interface is deleted. Fix the problem by clearing the pointer. 2) Fix memory leak issue by freeing 'wdev' in failure paths. Also, clear priv->wdev pointer. As mwifiex_add_virtual_intf() successfully handles the failure conditions, redundant code under err_add_intf label is removed in this patch. Reported-by:

Commit "rt2x00: fix HT TX descriptor settings regression" assumes that the control parameter to rt2x00mac_tx is always non-NULL. There is an internal call in rt2x00lib_bc_buffer_iter where NULL is passed. Fix the resulting crash by adding an initialized dummy on-stack ieee80211_tx_control struct.

On some boards which are based on AR9300, AR9580 or AR9550, MCS15 usage is problematic. This is because these boards use a "frequency doubler", which doubles the refclk to get better EVM, but causes spurs. Handle this properly in the driver to recover throughput. Signed-off-by:

A world regulatory domain check was in place that prevents user dynamic regulatory hints from being processed. This was there for historical reasons as this was only possible previously for world roaming cards and dynamic regulatory settings was only possible for country IEs. Fix this by enforcing the world regulatory domain check only for when the initiator is a country IE. Support for dynamic user regulatory support is already checked. Signed-off-by:

Currently, the PLL is turned off for AR9485 when switching to a low power state, but AR9485 has an issue where the card will become unresponsive if left idle for a long time without any traffic. To fix this, force the PLL to always be on using a different initval array, ar9485_1_1_pll_on_cdr_on_clkreq_disable_L1. This is done for most of the AR9485 based cards like HB125, WB225 etc. but certain models require the feature to be turned off. Identify such cards and use default values for them. Signed-off-by:

The routine that processes received frames was returning the RSSI value for the signal strength; however, that value is available only for associated APs. As a result, the strength was the absurd value of 10 dBm. As a result, scans return incorrect values for the strength, which causes unwanted attempts to roam. Signed-off-by:

All of the rtlwifi drivers have an error in the routine that tests if the data is "special". If it is, the subsequant transmission will be at the lowest rate to enhance reliability. The 16-bit quantity is big-endian, but was being extracted in native CPU mode. One of the effects of this bug is to inhibit association under some conditions as the TX rate is too high. Based on suggestions by Joe Perches, the entire routine is rewritten. One of the local headers contained duplicates of some of the ETH_P_XXX definitions. These are deleted. Signed-off-by:

Fix possible NULL (sc->dfs_detector) pointer dereference. Detected by Smatch: drivers/net/wireless/ath/ath9k/dfs_debug.c:67 read_file_dfs() error: we previously assumed 'sc->dfs_detector' could be null (see line 47) Signed-off-by:

If we do a zero size allocation then it will oops. Also we can't be sure the user passes us a NUL terminated string so I've added a terminator. This code can only be triggered by root. Reported-by:

kmalloc on efuse_word can return null, leading to free'ing of elements in efuse_word on the error exit path even though it has not been allocated. Instead, don't free the elements of efuse_word if kmalloc failed. Also, kmalloc of any of the arrays in efuse_word[] can also fail, leading to undefined contents in the remaining elements leading to problems when free'ing these elements later on. So kzalloc efuse_word to ensure the kfree on the remaining elements won't cause breakage. Signed-off-by:

As tlv_buf_len is decremented at the end of the loop, we may have accessed invalid memory in the last iteration. Modify the while condition and add a break statement at the begining of the loop to fix the problem. Reported-by:

With "while (length)" check we may end up in accessing invalid memory in last iteration. This patch makes sure that tlv length is not less than the length of structure mwifiex_power_group when min/max power is calculated. Reported-by:

__le16 to u16 conversion is missing for "pg_tlv_hdr->length" in mwifiex_get_power_level(). This creates a problem on big endian machines. It is resolved by changing definition of the structure and making required endianness changes. Signed-off-by:
