In <db3b9e990e75573402cda22faf933760f076c033> ("Staging: VME: move VME
drivers out of staging") the vme code, board and bridge drivers were
moved out of the staging tree, remaining only the VME user device
driver.
Since this driver is the only one remaining in staging, such multi-level
structure confuses more than helps. The current structure is as follows:
- drivers/staging/vme/
Makefile
devices/
Kconfig
Makefile
vme_user.c
vme_user.h
The top-level Makefile has the only function of calling another Makefile
into the devices/ subdirectory. This latter only compiles the vme_user
driver, since there is no other in the staging tree.
This patch removes the unnecessary Makefile from the 'vme/' dir, move
the contents of 'vme/devices' into the 'vme/' dir, and renames it to
'vme_user/' (the driver name), allowing a straightforward understanding
of this driver's contents. Furthermore, it updates the MAINTAINERS file
to properly reflect the new paths.

The KConfig file for VME_USER ('drivers/staging/vme/devices/Kconfig')
sourced at "drivers/vme/boards/KConfig" misses a `depends on` line for
VME_BUS, which is unnoticeable for menuconfig users who aren't be able
to select it through this interface without setting the CONFIG_VME_BUS
option because it's nested on VME_BUS menu entry.
A patch to move appropriately this driver to the "Staging" submenu
([PATCH 1/3], originally sent as a single patch submitted at
https://lore.kernel.org/linux-staging/3fbc5325e94b9ae0666a1f5a56a4e5372bfcea1d.camel@codeagain.dev/T/#t),
however, unveiled this missing `depends on` line, since it moved the
`source` line for VME_USER's KConfig to somewhere else, allowing it to
be compiled without the support for VME_BUS. While it compiles fine and
seems to initialize the driver fine (tested both as module and as built-
in), it seems to make no sense having VME_USER without VME_BUS.
This patches addresses it by adding the VME_BUS to the `depends on` line
at "drivers/staging/vme/devices/Kconfig".

Currently, the VME_USER driver is in the staging tree Kconfig, unlike
other VME drivers already moved to the main portions of the kernel tree.
Its configuration is, however, nested into the VME_BUS config option,
which might be misleading.
Since the staging tree "[...] is used to hold stand-alone drivers and
filesystem that are not ready to be merged into the main portion of the
Linux kernel tree [...]"(from
https://lore.kernel.org/all/20090320172502.GA14647@kroah.com/T/),
staging drivers should appear nested into the Main Menu -> Device
Drivers -> Staging Drivers to make sure the user don't pick it without
being fully aware of its staging status as it could be the case in
Menu -> Device Drivers -> VME bridge support (the current location).
With this change menuconfig users will clearly know this is not a driver
in the main portion of the kernel tree and decide whether to build it or
not with that clearly in mind.
This change goes into the same direction of commit
<4b4cdf3979c32fa3d042d150f49449c74d048553> ("STAGING: Move staging
drivers back to staging-specific menu")

Use the in-kernel structure and flags instead of defining a separate
one. The rtw_ieee80211_channel structure and flags can be replaced by
the ieee80211_channel defined in include/net/cfg80211.h since the flags
serve the same purpose and the ieee80211_channel struct includes the
elements used in the rtw_ieee80211_channel struct.

Unlike mlme_sta_tbl, OnAction_tbl is an array of structs.
OnAction iterates over the array to find the entry for a specific action
category. No action is performed if a category has no entry.
We can remove the entries that point to the dummy function DoReserved.
These were the last users of DoReserved, the function itself can be
removed as well.

The rtllib_rx_assoc_resp() function has a signedness bug because it's
a declared as a u16 but it return -ENOMEM. When you look at it more
closely it returns a mix of error codes including 0xcafe, -ENOMEM, and
a->status which is WLAN_STATUS_NOT_SUPPORTED_AUTH_ALG. This is a mess.
Clean it up to just return standard kernel error codes. We can print
out the a->status before returning a regular error code. The printks
in the caller need to be adjusted as well.

Currently, these three get_key functions return -1 when the provided len
value is less a specific key length value, which can result in buffer
overflow depending on how the returned value is used. These functions are
used in three places in ieee80211/ieee80211_wx.c:
ieee80211_wx_get_encode() :
The behavior of this function will be unchanged.
ieee80211_wx_get_encode_ext() :
The result of the get_key function is written to ext->key_len,
resulting in a buffer overflow if the result is negative.
ieee80211_wx_set_encode() :
The behavior of this function will change. When len is less than the
key length value, it will set a default key of all 0.

There is a deadlock in rtllib_beacons_stop(), which is shown
below:
(Thread 1) | (Thread 2)
| rtllib_send_beacon()
rtllib_beacons_stop() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | rtllib_send_beacon_cb()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold ieee->beacon_lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need ieee->beacon_lock in position (2) of thread 2.
As a result, rtllib_beacons_stop() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain
the needed lock.

Add " == 0" to the condition in both else if branches to address a
possible bug. strcmp returns 0 when its arguments are equal, which
evaluates to false, often leading to errors when used in if statements.
Currently, the statement in the first else if branch does not execute
when its arguments are equal, but it does execute when crypt->ops->name
equals any string other than "WEP" or "TKIP".
Similarly, the second else if branch does not execute when its arguments
are equal, and it only executes when crypt->ops->name equals "TKIP".
The else branch never executes.
It is unlikely that this is working as intended.

The Unisys sub-tree of drivers/staging contains three drivers for the
"Unisys Secure Partition" (s-Par(R)): visorhba, visorinput, visornic.
They have no maintainers, in fact the only one that is listed in
MAINTAINERS has an unreacheable email address. During 2021 and 2022
several patches have been submitted to these drivers but nobody at
Unisys cared of reviewing the changes. Probably, also the
"sparmaintainer" internal list of unisys.com is not anymore read by
interested Unisys' engineers.
Therefore, remove the drivers/staging/unisys directory and delete the
relevant entries in the MAINTAINERS, Kconfig, Makefile files, then
remove also the drivers/visorbus directory which is not anymore needed
(it contained the driver for the virtualized bus for the Unisys s-Par
firmware).

The size of struct rt_firmware_hdr is 36 bytes.
$ pahole -C rt_firmware_hdr drivers/staging/r8188eu/r8188eu.o
struct rt_firmware_hdr {
__le16 Signature; /* 0 2 */
u8 Category; /* 2 1 */
u8 Function; /* 3 1 */
__le16 Version; /* 4 2 */
u8 Subversion; /* 6 1 */
/* XXX 1 byte hole, try to pack */
u16 Rsvd1; /* 8 2 */
u8 Month; /* 10 1 */
u8 Date; /* 11 1 */
u8 Hour; /* 12 1 */
u8 Minute; /* 13 1 */
__le16 RamCodeSize; /* 14 2 */
u8 Foundry; /* 16 1 */
u8 Rsvd2; /* 17 1 */
/* XXX 2 bytes hole, try to pack */
__le32 SvnIdx; /* 20 4 */
u32 Rsvd3; /* 24 4 */
u32 Rsvd4; /* 28 4 */
u32 Rsvd5; /* 32 4 */
/* size: 36, cachelines: 1, members: 17 */
/* sum members: 33, holes: 2, sum holes: 3 */
/* last cacheline: 36 bytes */
};
But the header in the firmware file is only 32 bytes long.
The hexdump of rtl8188eufw.bin shows that the field Rsvd1 should be u8
instead of __le16.

Subversion Rsvd1 Month Date Hour Minute
With the change of field Rsvd1 from __le16 to u8 the structure has the
correct size 32.
$ pahole -C rt_firmware_hdr drivers/staging/r8188eu/r8188eu.o
struct rt_firmware_hdr {
__le16 Signature; /* 0 2 */
u8 Category; /* 2 1 */
u8 Function; /* 3 1 */
__le16 Version; /* 4 2 */
u8 Subversion; /* 6 1 */
u8 Rsvd1; /* 7 1 */
u8 Month; /* 8 1 */
u8 Date; /* 9 1 */
u8 Hour; /* 10 1 */
u8 Minute; /* 11 1 */
__le16 RamCodeSize; /* 12 2 */
u8 Foundry; /* 14 1 */
u8 Rsvd2; /* 15 1 */
__le32 SvnIdx; /* 16 4 */
u32 Rsvd3; /* 20 4 */
u32 Rsvd4; /* 24 4 */
u32 Rsvd5; /* 28 4 */
/* size: 32, cachelines: 1, members: 17 */
/* last cacheline: 32 bytes */
The wrong size had no effect because the header size is hardcoded to
32 where it is used in the code and the fields after Subversion are
not used.
