This is an announce of the Linux IPsec workshop 2018. The workshop
will take place in Dresden, Germany, from 26th to 28th March 2018.
The workshop is invitation based and limited to ca. 20 - 25 IPsec
developers from user and kernel space. We almost reached the limit,

Hi Broadcom folks,
We are now enabling a new platform with tg3 nic, unfortunately we observed
the bug [1] that dated back to 2015.
I tried commit 4419bb1cedcd ("tg3: Add workaround to restrict 5762 MRRS to
2048”) but it does’t work.
Do you have any idea how to solve the issue?

Hi
I'm using tcp_probe tracepoint as [1]. It takes a snapshot each time
tcp_rcv_established() is called. However I need to take a snapshot
only when congestion window changes. Old tcp_probe had full=0 option
to achieve this. Is there a way to achieve this using tcp_probe
tracepoint?

By storing subprog boundaries as a subprogno mark on each insn, rather than

The json print library was toggling pretty print at the end of
an array to workaround a bug in underlying json_writer.
Instead, just fix json_writer to pretty print array correctly.

Since JSON is intended for programmatic consumption, it makes
sense for the default output format to be concise as possible.
For programmer and other uses, it is helpful to keep the pretty
whitespace format; therefore enable it with -p flag.

In commit d618d09a68e4 ("tipc: enforce valid ratio between skb truesize
and contents") we introduced a test for ensuring that the condition
truesize/datasize <= 4 is true for a received buffer. Unfortunately this
test has two problems.
- Because of the integer arithmetics the test

In gre/gre6 for non-JSON output 0x%x format is used: use print_0xhex()
to get the same value for JSON.
Get rid of custom _print_hex() in bridge slave code: print_0xhex() can
be used perfectly.
Break long print_uint() with long argument list to fit into 80 columns.

Don't put buffers of data to be handed to crypto on the stack as this may
cause an assertion failure in the kernel (see below). Fix this by using an
kmalloc'd buffer instead.
