[ Upstream commit 216b44000ada87a63891a8214c347e05a4aea8fe ]
The brcmu_pkt_buf_free_skb() function frees "pkt" so it leads to a
static checker warning:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:1974 brcmf_sdio_readframes()
error: dereferencing freed memory 'pkt'
It looks like there was supposed to be a continue after we free "pkt".

[ Upstream commit c26a2c2ddc0115eb088873f5c309cf46b982f522 ]
The driver wrongly assumes that it is the only entity that can set the
SKBTX_IN_PROGRESS bit of the current skb. Therefore, in the
gfar_clean_tx_ring function, where the TX timestamp is collected if
necessary, the aforementioned bit is used to discriminate whether or not
the TX timestamp should be delivered to the socket's error queue.
But a stacked driver such as a DSA switch can also set the
SKBTX_IN_PROGRESS bit, which is actually exactly what it should do in
order to denote that the hardware timestamping process is undergoing.
Therefore, gianfar would misinterpret the "in progress" bit as being its
own, and deliver a second skb clone in the socket's error queue,
completely throwing off a PTP process which is not expecting to receive
it, _even though_ TX timestamping is not enabled for gianfar.
There have been discussions [0] as to whether non-MAC drivers need or
not to set SKBTX_IN_PROGRESS at all (whose purpose is to avoid sending 2
timestamps, a sw and a hw one, to applications which only expect one).
But as of this patch, there are at least 2 PTP drivers that would break
in conjunction with gianfar: the sja1105 DSA switch and the felix
switch, by way of its ocelot core driver.
So regardless of that conclusion, fix the gianfar driver to not do stuff
based on flags set by others and not intended for it.

Commit e5e884b42639 ("libertas: Fix two buffer overflows at parsing bss
descriptor") introduced a bounds check on the number of supplied rates to
lbs_ibss_join_existing() and made it to return on overflow.
However, the aforementioned commit doesn't set the return value accordingly
and thus, lbs_ibss_join_existing() would return with zero even though it
failed.
Make lbs_ibss_join_existing return -EINVAL in case the bounds check on the
number of supplied rates fails.

[ Upstream commit b33bdf8020c94438269becc6dace9ed49257c4ba ]
As everybody pointed out by now, my patch to clean up CAPI introduced
a link time warning, as the two parts of the capi driver are now in
one module and the exit function may need to be called in the error
path of the init function:
>> WARNING: drivers/isdn/capi/kernelcapi.o(.text+0xea4): Section mismatch in reference from the function kcapi_exit() to the function .exit.text:kcapi_proc_exit()
The function kcapi_exit() references a function in an exit section.
Often the function kcapi_proc_exit() has valid usage outside the exit section
and the fix is to remove the __exit annotation of kcapi_proc_exit.
Remove the incorrect __exit annotation.

In ezusb_init, if upriv is NULL, the code crashes. However, the caller
in ezusb_probe can handle the error and print the failure message.
The patch replaces the BUG_ON call to error return.

From: Andrey Zhizhikin <andrey.z@gmail.com>
[ Upstream commit 6794200fa3c9c3e6759dae099145f23e4310f4f7 ]
GCC9 introduced string hardening mechanisms, which exhibits the error
during fs api compilation:
error: '__builtin_strncpy' specified bound 4096 equals destination size
[-Werror=stringop-truncation]
This comes when the length of copy passed to strncpy is is equal to
destination size, which could potentially lead to buffer overflow.
There is a need to mitigate this potential issue by limiting the size of
destination by 1 and explicitly terminate the destination with NULL.

[ Upstream commit b61156fba74f659d0bc2de8f2dbf5bad9f4b8faf ]
Clang warns:
../drivers/net/wireless/intersil/hostap/hostap_ap.c:2511:3: warning:
misleading indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
if (sta->tx_supp_rates & WLAN_RATE_5M5)

previous statement is here

1 warning generated.
This warning occurs because there is a space before the tab on this
line. Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.

[ Upstream commit c2f9a4e4a5abfc84c01b738496b3fd2d471e0b18 ]
The loop counter addr is a u16 where as the upper limit of the loop
is an int. In the unlikely event that the il->cfg->eeprom_size is
greater than 64K then we end up with an infinite loop since addr will
wrap around an never reach upper loop limit. Fix this by making addr
an int.
Addresses-Coverity: ("Infinite loop")

[ Upstream commit 3a9b153c5591548612c3955c9600a98150c81875 ]
mwifiex_ret_wmm_get_status() calls memcpy() without checking the
destination size.Since the source is given from remote AP which
contains illegal wmm elements , this may trigger a heap buffer
overflow.
Fix it by putting the length check before calling memcpy().

mwifiex_cmd_append_vsie_tlv() calls memcpy() without checking
the destination size may trigger a buffer overflower,
which a local user could use to cause denial of service
or the execution of arbitrary code.
Fix it by putting the length check before calling memcpy().
