2021-06-02media: v4l: async, fwnode: Improve module organisationSakari Ailus
The V4L2 async framework is generally used with the V4L2 fwnode, which also depends on the former. There are a few exceptions but they are relatively few. At the same time there is a vast number of systems that need videodev module, but have no use for v4l2-async that's now part of videodev. In order to improve, split the v4l2-async into its own module. Selecting V4L2_FWNODE also selects V4L2_ASYNC. This also moves the initialisation of the debufs entries for async subdevs to loading of the v4l2-async module. The directory is named as "v4l2-async".

2021-06-02media: mc-request.c: allow object_bind in QUEUED stateHans Verkuil
If a request was queued without a control handler object, and a control handler object is then created and bound to the request when copying controls on request completion, then a WARN_ON in mc-request.c is triggered since at that time the request is in state QUEUED, and not UPDATING. But this is too strict, and in this case it must also allow binding objects when in state QUEUED. This patch was unfortunately lost when the "always copy the controls on completion" patch was posted, it should have been part of that commit.

2021-06-02media: sp8870: move it to stagingMauro Carvalho Chehab
This driver is used only by av7110, which is preparing for its retirement. So, move this ancillary driver to stay together with av7110. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-06-02media: av7110: move driver to stagingMauro Carvalho Chehab
This driver is really old, from devices that aren't manufactured anymore for more than a decade. Also, the decoder supports only MPEG2, with is not compatible with several modern DVB streams. It is also the only upstream driver relying on the DVB "full-featured" API. Some changes at the frontend drivers seem to have broken it without anybody noticing. Due to that, it sounds it is time to retire the driver for good. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2021-06-02media: move ttpci-eeprom to commonMauro Carvalho Chehab
The ttpci-eeprom is actually an independent driver that doesn't depend on the stuff under drivers/media/pci/ttpci/. Also, it is used by an USB driver (pctv452e). So, move it to the common directory. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Pull xfs fixes from Darrick Wong: "This week's pile mitigates some decades-old problems in how extent size hints interact with realtime volumes, fixes some failures in online shrink, and fixes a problem where directory and symlink shrinking on extremely fragmented filesystems could fail. The most user-notable change here is to point users at our (new) IRC channel on OFTC. Freedom isn't free, it costs folks like you and me; and if you don't kowtow, they'll expel everyone and take over your channel. (Ok, ok, that didn't fit the song lyrics...) Summary: - Fix a bug where unmapping operations end earlier than expected, which can cause chaos on multi-block directory and symlink shrink operations. - Fix an erroneous assert that can trigger if we try to transition a bmap structure from btree format to extents format with zero extents.

2021-05-29seccomp: Refactor notification handler to prepare for new semanticsSargun Dhillon
This refactors the user notification code to have a do / while loop around the completion condition. This has a small change in semantic, in that previously we ignored addfd calls upon wakeup if the notification had been responded to, but instead with the new change we check for an outstanding addfd calls prior to returning to userspace. Rodrigo Campos also identified a bug that can result in addfd causing an early return, when the supervisor didn't actually handle the syscall [1].

vm_create allocates memory and maps it close to GPA. This memory is separate from what is allocated in subsequent calls to vm_userspace_mem_region_add, so it is incorrect to pass the test memory size to vm_create_default. Just pass a small fixed amount of memory which can be used later for page table, otherwise GPAs are already allocated at MEM_GPA and the test aborts.

2021-05-28i2c: s3c2410: fix possible NULL pointer deref on read message after writeKrzysztof Kozlowski
Interrupt handler processes multiple message write requests one after another, till the driver message queue is drained. However if driver encounters a read message without preceding START, it stops the I2C transfer as it is an invalid condition for the controller. At least the comment describes a requirement "the controller forces us to send a new START when we change direction". This stop results in clearing the message queue (i2c->msg = NULL). The code however immediately jumped back to label "retry_write" which dereferenced the "i2c->msg" making it a possible NULL pointer dereference. The Coverity analysis: 1. Condition !is_msgend(i2c), taking false branch. if (!is_msgend(i2c)) { 2. Condition !is_lastmsg(i2c), taking true branch. } else if (!is_lastmsg(i2c)) { 3. Condition i2c->msg->flags & 1, taking true branch. if (i2c->msg->flags & I2C_M_RD) { 4. write_zero_model: Passing i2c to s3c24xx_i2c_stop, which sets i2c->msg to NULL. s3c24xx_i2c_stop(i2c, -EINVAL); 5. Jumping to label retry_write. goto retry_write; 6. var_deref_model: Passing i2c to is_msgend, which dereferences null i2c->msg. if (!is_msgend(i2c)) {" All previous calls to s3c24xx_i2c_stop() in this interrupt service routine are followed by jumping to end of function (acknowledging the interrupt and returning). This seems a reasonable choice also here since message buffer was entirely emptied.

2021-05-27i2c: i801: Don't generate an interrupt on bus resetJean Delvare
Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling the end of a successful transaction. In the case of a block transaction, this can result in an out-of-range memory access. This condition was reproduced several times by syzbot: https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79 So disable interrupts while trying to reset the bus.
