Subject: [PATCH 01/10] Bluetooth: allocate static minor for vhci
|
|
||||||
|
|
||||||
Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI
|
|
||||||
driver) added the module alias to hci_vhci module so it's possible to
|
|
||||||
create the /dev/vhci node. However creating an alias without
|
|
||||||
specifying the minor doesn't allow us to create the node ahead,
|
|
||||||
triggerring module auto-load when it's first accessed.
|
|
||||||
|
|
||||||
Starting with depmod from kmod 16 we started to warn if there's a
|
|
||||||
devname alias without specifying the major and minor.
|
|
||||||
|
|
||||||
Let's do the same done for uhid, kvm, fuse and others, specifying a
|
|
||||||
fixed minor. In systems with systemd as the init the following will
|
|
||||||
happen: on early boot systemd will call "kmod static-nodes" to read
|
|
||||||
/lib/modules/$(uname -r)/modules.devname and then create the nodes. When
|
|
||||||
first accessed these "dead" nodes will trigger the module loading.

Subject: [PATCH 02/10] module: allow multiple calls to MODULE_DEVICE_TABLE()
|
|
||||||
per module
|
|
||||||
|
|
||||||
Commit 78551277e4df5: "Input: i8042 - add PNP modaliases" had a bug, where the
|
|
||||||
second call to MODULE_DEVICE_TABLE() overrode the first resulting in not all
|
|
||||||
the modaliases being exposed.
|
|
||||||
|
|
||||||
This fixes the problem by including the name of the device_id table in the
|
|
||||||
__mod_*_device_table alias, allowing us to export several device_id tables
|
|
||||||
per module.

Subject: [PATCH 03/10] module: remove MODULE_GENERIC_TABLE
|
|
||||||
|
|
||||||
MODULE_DEVICE_TABLE() calles MODULE_GENERIC_TABLE(); make it do the
|
|
||||||
work directly. This also removes a wart introduced in the last patch,
|
|
||||||
where the alias is defined to be an unknown struct type "struct
|
|
||||||
type##__##name##_device_id" instead of "struct type##_device_id" (it's
|
|
||||||
an extern so GCC doesn't care, but it's wrong).
|
|
||||||
|
|
||||||
The other user of MODULE_GENERIC_TABLE (ISAPNP_CARD_TABLE) is unused,
|
|
||||||
so delete it.

code32_start should point at the start of the protected mode code, and

*not* at the beginning of the bzImage. This is much easier to do in

assembly so document that callers of make_boot_params() need to fill out

code32_start.
|
|

|

The fallout from this bug is that we would end up relocating the image

but copying the image at some offset, resulting in what appeared to be
|
|

memory corruption.

Subject: [PATCH 08/10] futex: avoid race between requeue and wake
|
|
||||||
|
|
||||||
commit 69cd9eba38867a493a043bb13eb9b33cad5f1a9a upstream.
|
|
||||||
|
|
||||||
Jan Stancek reported:
|
|
||||||
"pthread_cond_broadcast/4-1.c testcase from openposix testsuite (LTP)
|
|
||||||
occasionally fails, because some threads fail to wake up.
|
|
||||||
|
|
||||||
Testcase creates 5 threads, which are all waiting on same condition.
|
|
||||||
Main thread then calls pthread_cond_broadcast() without holding mutex,
|
|
||||||
which calls:
|
|
||||||
|
|
||||||
futex(uaddr1, FUTEX_CMP_REQUEUE_PRIVATE, 1, 2147483647, uaddr2, ..)
|
|
||||||
|
|
||||||
This immediately wakes up single thread A, which unlocks mutex and
|
|
||||||
tries to wake up another thread:
|
|
||||||
|
|
||||||
futex(uaddr2, FUTEX_WAKE_PRIVATE, 1)
|
|
||||||
|
|
||||||
If thread A manages to call futex_wake() before any waiters are
|
|
||||||
requeued for uaddr2, no other thread is woken up"
|
|
||||||
|
|
||||||
The ordering constraints for the hash bucket waiter counting are that
|
|
||||||
the waiter counts have to be incremented _before_ getting the spinlock
|
|
||||||
(because the spinlock acts as part of the memory barrier), but the
|
|
||||||
"requeue" operation didn't honor those rules, and nobody had even
|
|
||||||
thought about that case.
|
|
||||||
|
|
||||||
This fairly simple patch just increments the waiter count for the target
|
|
||||||
hash bucket (hb2) when requeing a futex before taking the locks. It
|
|
||||||
then decrements them again after releasing the lock - the code that
|
|
||||||
actually moves the futex(es) between hash buckets will do the additional
|
|
||||||
required waiter count housekeeping.

Subject: [PATCH 09/10] iwlwifi: mvm: rs: fix search cycle rules
|
|

|
|

commit 8930b05090acd321b1fc7c642528c697cb105c42 upstream.
|
|
||||||
|
|
||||||
We should explore all possible columns when searching to be
|
|
||||||
as resilient as possible to changing conditions. This fixes
|
|
||||||
for example a scenario where even after a sudden creation of
|
|
||||||
rssi difference between the 2 antennas we would keep doing MIMO
|
|
||||||
at a low rate instead of switching to SISO at a higher rate using
|
|
||||||
the better antenna which was the optimal configuration.
