In addition to knowing the 4-tuple of the flow which generates RST,
the reason why it does so is very important because we have some
cases where the RST should be sent and have no clue which one
exactly.
Adding location of reset process can help us more, like what

Prior to this patch, what we can see by enabling trace_tcp_send is
only happening under two circumstances:
1) active rst mode
2) non-active rst mode and based on the full socket
That means the inconsistency occurs if we use tcpdump and trace
simultaneously to see how rst happens
From: Jason Xing
Introducing entry_saddr and entry_daddr parameters in this macro
for later use can help us record the reverse 4-tuple by analyzing
the 4-tuple of the incoming skb when receiving.

Before this, we miss some cases where the TCP layer could send RST but
we cannot trace it. So I decided to complete it :)

Machine Check Error information from struct mce is exported to userspace
through the mce_record tracepoint.
Currently, however, the PPIN (Protected Processor Inventory Number) field
of struct mce is not exported through the tracepoint.
Export PPIN through the tracepoint as it provides a unique id
Currently, the microcode field (Microcode Revision) of struct mce is not
exported to userspace through the mce_record tracepoint.
Knowing the microcode version on which the MCE was received is critical
information for debugging. If the version is not recorded, later attempts
to acquire the version
This patchset updates the mce_record tracepoint so that the recently added
fields of struct mce are exported through it to userspace.
The first patch adds PPIN (Protected Processor Inventory Number) field to
the tracepoint.
The second patch adds the microcode field (Microcode Revision) to the

We are close to being able to turn on -Wstringop-truncation
unconditionally instead of only at the 'make W=1' level, these ten
warnings are all that I saw in randconfig testing across compiler versions
on arm, arm64 and x86.
The final patch is only there for reference at the
