Andrey Konovalov got crashes in __ip_options_echo() when a NULL skb->dst
|
||||
is accessed.
|
||||
|
||||
ipv4_pktinfo_prepare() should not drop the dst if (evil) IP options
|
||||
are present.
|
||||
|
||||
We could refine the test to the presence of ts_needtime or srr,
|
||||
but IP options are not often used, so let's be conservative.
|
||||
|
||||
Thanks to syzkaller team for finding this bug.

Subject: sctp: avoid BUG_ON on sctp_wait_for_sndbuf
|
||||
Origin: https://git.kernel.org/linus/2dcab598484185dea7ec22219c76dcdd59e3cb90
|
||||
|
||||
Alexander Popov reported that an application may trigger a BUG_ON in
|
||||
sctp_wait_for_sndbuf if the socket tx buffer is full, a thread is
|
||||
waiting on it to queue more data and meanwhile another thread peels off
|
||||
the association being used by the first thread.
|
||||
|
||||
This patch replaces the BUG_ON call with a proper error handling. It
|
||||
will return -EPIPE to the original sendmsg call, similarly to what would
|
||||
have been done if the association wasn't found in the first place.

|
||||
|
||||
The accelerometer event relies on the ACERWMID_EVENT_GUID notify.
|
||||
So, this patch changes the codes to setup accelerometer input device
|
||||
when detected ACERWMID_EVENT_GUID. It avoids that the accel input
|
||||
device created on every Acer machines.
|
||||
|
||||
In addition, patch adds a clearly parsing logic of accelerometer hid
|
||||
to acer_wmi_get_handle_cb callback function. It is positive matching
|
||||
the "SENR" name with "BST0001" device to avoid non-supported hardware.

Subject: x86/xen: Fix APIC id mismatch warning on Intel
|

Origin: https://git.kernel.org/linus/cc272163ea554a97dac180fa8dd6cd54c2810bd1
|
||||
Bug-Debian: https://bugs.debian.org/853193
|
||||
|
||||
This patch fixes the following warning message seen when booting the
|
||||
kernel as Dom0 with Xen on Intel machines.
|
||||
|
||||
[0.003000] [Firmware Bug]: CPU1: APIC id mismatch. Firmware: 0 APIC: 1]
|
||||
|
||||
The code generating the warning in validate_apic_and_package_id() matches
|
||||
cpu_data(cpu).apicid (initialized in init_intel()->
|
||||
detect_extended_topology() using cpuid) against the apicid returned from
|
||||
xen_apic_read(). Now, xen_apic_read() makes a hypercall to retrieve apicid
|
||||
for the boot cpu but returns 0 otherwise. Hence the warning gets thrown
|
||||
for all but the boot cpu.
|
||||
|
||||
The idea behind xen_apic_read() returning 0 for apicid is that the
|
||||
guests (even Dom0) should not need to know what physical processor their
|
||||
vcpus are running on. This is because we currently do not have topology
|
||||
information in Xen and also because xen allows more vcpus than physical
|
||||
processors. However, boot cpu's apicid is required for loading
|
||||
xen-acpi-processor driver on AMD machines. Look at following patch for
|
||||
details:
|
||||
|
||||
commit 558daa289a40 ("xen/apic: Return the APIC ID (and version) for CPU
|
||||
0.")
|
||||
|
||||
So to get rid of the warning, this patch modifies
|
||||
xen_cpu_present_to_apicid() to return cpu_data(cpu).apicid instead of
|
||||
calling xen_apic_read().
|
||||
|
||||
The warning is not seen on AMD machines because init_amd() populates
|
||||
cpu_data(cpu).apicid by calling hard_smp_processor_id()->xen_apic_read()
|
||||
as opposed to using apicid from cpuid as is done on Intel machines.

|

We can mitigate the effect of vulnerabilities in obscure protocols by
|
||||
preventing unprivileged users from loading the modules, so that they
|
||||
are only exploitable on systems where the administrator has chosen to
|
||||
load the protocol.
|

|

The 'dccp' protocol is not actively maintained or widely used.

Therefore disable auto-loading.

|

Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/older/patches-4.9-rt1.tar.xz
|
||||
|
||||
The previous patch removed a trace point due to a use after free problem
|
||||
with tracing enabled. While looking at the backtrace it took me a while
|
||||
to find the right spot. While doing so I noticed that this trace point
|
||||
could be used with two clean-up functions in run_ordered_work():
|
||||
- run_one_async_free()
|
||||
- async_cow_free()
|
||||
|
||||
Both of them free the `work' item so a later use in the tracepoint is
|
||||
not possible.
|
||||
This patches swaps the order so we first have the trace point and then
|
||||
free the struct.

The later ensured that a NUMA box WILL take callback_lock in atomic
|
||||
context by removing the allocator and reclaim path __GFP_HARDWALL
|
||||
usage which prevented such contexts from taking callback_mutex.
|
||||
|
||||
One option would be to reinstate __GFP_HARDWALL protections for
|
||||
RT, however, as the 8447a0fee974 changelog states:
|
||||
|
||||
The callback_mutex is only used to synchronize reads/updates of cpusets'
|
||||
flags and cpu/node masks. These operations should always proceed fast so
|
||||
there's no reason why we can't use a spinlock instead of the mutex.
