Subject: [PATCH] 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.

|
||||
|
||||
When netback discovers frontend is sending malformed packet it will
|
||||
disables the interface which serves that frontend.
|
||||
|
||||
However disabling a network interface involving taking a mutex which
|
||||
cannot be done in softirq context, so we need to defer this process to
|
||||
kthread context.
|
||||
|
||||
This patch does the following:
|
||||
1. introduce a flag to indicate the interface is disabled.
|
||||
2. check that flag in TX path, don't do any work if it's true.
|
||||
3. check that flag in RX path, turn off that interface if it's true.
|
||||
|
||||
The reason to disable it in RX path is because RX uses kthread. After
|
||||
this change the behavior of netback is still consistent -- it won't do
|
||||
any TX work for a rogue frontend, and the interface will be eventually
|
||||
turned off.
|
||||
|
||||
Also change a "continue" to "break" after xenvif_fatal_tx_err, as it
|
||||
doesn't make sense to continue processing packets if frontend is rogue.
|
||||
|
||||
This is a fix for XSA-90.

without checking.
