2023-12-24netfs, fscache: Move /proc/fs/fscache to /proc/fs/netfs and put in a symlinkDavid Howells7-32/+62

2023-12-24netfs, fscache: Combine fscache with netfsDavid Howells18-311/+237
Now that the fscache code is moved to be colocated with the netfslib code so that they combined into one module, do the combining.

2023-12-24netfs, fscache: Move fs/fscache/* into fs/netfs/David Howells17-69/+73
There's a problem with dependencies between netfslib and fscache as each wants to access some functions of the other. Deal with this by moving fs/fscache/* into fs/netfs/ and renaming those files to begin with "fscache-". For the moment, the moved files are changed as little as possible and an fscache module is still built. A subsequent patch will integrate them.

2023-12-23Input: soc_button_array - add mapping for airplane mode buttonChristoffer Sandberg1-0/+5
This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3. While it is physically a key it behaves more like a switch, sending a key down on first press and a key up on 2nd press. Therefor the switch event is used here. Besides this behaviour it uses the HID usage-id 0xc6 (Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but since neither 0xc6 nor 0xc8 are currently implemented at all in soc_button_array this not to standard behaviour is not put behind a quirk for the moment.

Tetsuo Handa pointed out that in the (now reverted) lockdep commit I initialized the data too late. The same is true for the cancellation data, it must be initialized before the cmpxchg(), otherwise it may be done twice and possibly even overwriting data in there already when there's a race.

2023-12-21afs: Fix use-after-free due to get/remove race in volume treeDavid Howells2-3/+25
When an afs_volume struct is put, its refcount is reduced to 0 before the cell->volume_lock is taken and the volume removed from the cell->volumes tree. Unfortunately, this means that the lookup code can race and see a volume with a zero ref in the tree, resulting in a use-after-free: refcount_t: addition on 0; use-after-free. WARNING: CPU: 3 PID: 130782 at lib/refcount.c:25 refcount_warn_saturate+0x7a/0xda ... RIP: 0010:refcount_warn_saturate+0x7a/0xda ...

(2) When looking up, use a conditional ref increment and if it fails because the refcount is 0, replace the node in the tree and set the removal flag.

2023-12-21afs: Fix overwriting of result of DNS queryDavid Howells1-2/+4
In afs_update_cell(), ret is the result of the DNS lookup and the errors are to be handled by a switch - however, the value gets clobbered in between by setting it to -ENOMEM in case afs_alloc_vlserver_list() fails. Fix this by moving the setting of -ENOMEM into the error handling for OOM failure. Further, only do it if we don't have an alternative error to return.

2023-12-21tracing / synthetic: Disable events after testing in synth_event_gen_test_init()Steven Rostedt (Google)1-0/+11
The synth_event_gen_test module can be built in, if someone wants to run the tests at boot up and not have to load them. The synth_event_gen_test_init() function creates and enables the synthetic events and runs its tests. The synth_event_gen_test_exit() disables the events it created and destroys the events. If the module is builtin, the events are never disabled. The issue is, the events should be disable after the tests are run. This could be an issue if the rest of the boot up tests are enabled, as they expect the events to be in a known state before testing. That known state happens to be disabled.

2023-12-21keys, dns: Allow key types (eg. DNS) to be reclaimed immediately on expiryDavid Howells6-23/+47
If a key has an expiration time, then when that time passes, the key is left around for a certain amount of time before being collected (5 mins by default) so that EKEYEXPIRED can be returned instead of ENOKEY. This is a problem for DNS keys because we want to redo the DNS lookup immediately at that point. Fix this by allowing key types to be marked such that keys of that type don't have this extra period, but are reclaimed as soon as they expire and turn this on for dns_resolver-type keys. To make this easier to handle, key->expiry is changed to be permanent if TIME64_MAX rather than 0. Furthermore, give such new-style negative DNS results a 1s default expiry if no other expiry time is set rather than allowing it to stick around indefinitely. This shouldn't be zero as ls will follow a failing stat call immediately with a second with AT_SYMLINK_NOFOLLOW added.

2023-12-21gpio: dwapb: mask/unmask IRQ when disable/enale itxiongxin1-4/+8
In the hardware implementation of the I2C HID driver based on DesignWare GPIO IRQ chip, when the user continues to use the I2C HID device in the suspend process, the I2C HID interrupt will be masked after the resume process is finished. This is because the disable_irq()/enable_irq() of the DesignWare GPIO driver does not synchronize the IRQ mask register state. In normal use of the I2C HID procedure, the GPIO IRQ irq_mask()/irq_unmask() functions are called in pairs. In case of an exception, i2c_hid_core_suspend() calls disable_irq() to disable the GPIO IRQ. With low probability, this causes irq_unmask() to not be called, which causes the GPIO IRQ to be masked and not unmasked in enable_irq(), raising an exception. Add synchronization to the masked register state in the dwapb_irq_enable()/dwapb_irq_disable() function. mask the GPIO IRQ before disabling it. After enabling the GPIO IRQ, unmask the IRQ.

2023-12-21net: check dev->gso_max_size in gso_features_check()Eric Dumazet1-0/+3
Some drivers might misbehave if TSO packets get too big. GVE for instance uses a 16bit field in its TX descriptor, and will do bad things if a packet is bigger than 2^16 bytes. Linux TCP stack honors dev->gso_max_size, but there are other ways for too big packets to reach an ndo_start_xmit() handler : virtio_net, af_packet, GRO... Add a generic check in gso_features_check() and fallback to GSO when needed. gso_max_size was added in the blamed commit.

There's one framework fix for the HDMI CODEC where it wasn't handling startup properly for some controllers, and one new x86 quirk, but otherwise all local fixes or dropping things we don't want to see in a release.
2023-12-21pinctrl: at91-pio4: use dedicated lock class for IRQAlexis Lothoré1-0/+8

Whenever a wake up source configures an IRQ through irq_set_irq_wake, it will lock the corresponding IRQ desc, and then call irq_set_irq_wake on "parent" IRQ which will do the same on its own IRQ desc, but since those two locks share the same class, lockdep reports this as an issue. Fix lockdep false positive by setting a different class for parent and children IRQ Fixes: 776180848b57 ("pinctrl: introduce driver for Atmel PIO4 controller") Signed-off-by: Alexis Lothoré <alexis.lothore@bootlin.com> Link: https://lore.kernel.org/r/20231215-lockdep_warning-v1-1-8137b2510ed5@bootlin.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
