2022-05-12USB: serial: whiteheat: fix heap overflow in WHITEHEAT_GET_DTR_RTSKees Cook
commit e23e50e7acc8d8f16498e9c129db33e6a00e80eb upstream. The sizeof(struct whitehat_dr_info) can be 4 bytes under CONFIG_AEABI=n due to "-mabi=apcs-gnu", even though it has a single u8: whiteheat_private { __u8 mcr; /* 0 1 */ /* size: 4, cachelines: 1, members: 1 */ /* padding: 3 */ /* last cacheline: 4 bytes */ }; The result is technically harmless, as both the source and the destinations are currently the same allocation size (4 bytes) and don't use their padding, but if anything were to ever be added after the "mcr" member in "struct whiteheat_private", it would be overwritten. The structs both have a single u8 "mcr" member, but are 4 bytes in padded size. The memcpy() destination was explicitly targeting the u8 member (size 1) with the length of the whole structure (size 4), triggering the memcpy buffer overflow warning: In file included from include/linux/string.h:253, from include/linux/bitmap.h:11, from include/linux/cpumask.h:12, from include/linux/smp.h:13, from include/linux/lockdep.h:14, from include/linux/spinlock.h:62, from include/linux/mmzone.h:8, from include/linux/gfp.h:6, from include/linux/slab.h:15, from drivers/usb/serial/whiteheat.c:17: In function 'fortify_memcpy_chk', inlined from 'firm_send_command' at drivers/usb/serial/whiteheat.c:587:4: include/linux/fortify-string.h:328:25: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()?

2017-11-04USB: serial: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2015-09-23USB: whiteheat: fix potential null-deref at probeJohan Hovold
Fix potential null-pointer dereference at probe by making sure that the required endpoints are present. The whiteheat driver assumes there are at least five pairs of bulk endpoints, of which the final pair is used for the "command port". An attempt to bind to an interface with fewer bulk endpoints would currently lead to an oops. Fixes CVE-2015-5257.

2014-08-24USB: whiteheat: Added bounds checking for bulk command responseJames Forshaw
This patch fixes a potential security issue in the whiteheat USB driver which might allow a local attacker to cause kernel memory corrpution. This is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On EHCI and XHCI busses it's possible to craft responses greater than 64 bytes leading a buffer overflow.

2013-06-17USB: serial: make minor allocation dynamicGreg Kroah-Hartman
This moves the allocation of minor device numbers from a static array to be dynamic, using the idr interface. This means that you could potentially get "gaps" in a minor number range for a single USB serial device with multiple ports, but all should still work properly. We remove the 'minor' field from the usb_serial structure, as it no longer makes any sense for it (use the field in the usb_serial_port structure if you really want to know this number), and take the fact that we were overloading a number in this field to determine if we had initialized the minor numbers or not, and just use a flag variable instead. Note, we still have the limitation of 255 USB to serial devices in the system, as that is all we are registering with the TTY layer at this point in time.

2013-06-10USB: serial: ports: add minor and port numberGreg Kroah-Hartman
The usb_serial_port structure had the number field, which was the minor number for the port, which almost no one really cared about. They really wanted the number of the port within the device, which you had to subtract from the minor of the parent usb_serial_device structure. To clean this up, provide the real minor number of the port, and the number of the port within the serial device separately, as these numbers might not be related in the future. Bonus is that this cleans up a lot of logic in the drivers, and saves lines overall.

Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no driver is bound) the port private data is no longer freed at release as it is no longer accessible.

For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-11-15USB: serial: remove unnecessary reinitialisations of urb->devJohan Hovold
Remove unnecessary reinitialisations of urb->dev before each submission, which were based on the (no longer valid) assumption that serial->dev will be set to NULL on close. Compile-only tested.

We don't use it so we can trim it from here as we try and stamp the file object dependencies out of the serial code. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-02-17tiocmget: kill off the passing of the struct fileAlan Cox
We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

2010-08-10drivers/usb: Remove unnecessary return's from void functionsJoe Perches
Greg prefers this to go through the trivial tree. http://lkml.org/lkml/2010/6/24/1 There are about 2500 void functions in drivers/usb Only a few used return; at end of function.

2010-03-02USB serial: make USB device id constantNémeth Márton
The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Németh Márton <nm127@freemail.hu> Cc: Julia Lawall <julia@diku.dk> Cc: cocci@diku.dk Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-10-09USB: serial: fix assumption that throttle/unthrottle cannot sleepOliver Neukum
many serial subdrivers are clearly written as if throttle/unthrottle cannot sleep. This leads to unneeded atomic submissions. This patch converts affected drivers in a way to makes very clear that throttle/unthrottle can sleep. Thus future misdesigns can be avoided and efficiency and reliability improved. This removes any such assumption using GFP_KERNEL and spin_lock_irq() Signed-off-by: Oliver Neukum <oliver@neukum.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-19tty: USB serial termios bitsAlan Cox

2009-06-15USB: usb-serial: replace shutdown with disconnect, releaseAlan Stern
This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

2009-06-11tty: Bring the usb tty port structure into more useAlan Cox
This allows us to clean stuff up, but is probably also going to cause some app breakage with buggy apps as we now implement proper POSIX behaviour for USB ports matching all the other ports. This does also mean other apps that break on USB will now work properly. Signed-off-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
