Hey gang,
I have added SPF record for my domains about 2 years ago and kinda
forgot about it. I get a lot of reports about spam received "from my
domain" but not from my servers. almost 50% from google, and I assume
that's because half the world in on gmail...
however today I found a report
don't feel like
hosting unmaintainable old php code that is quite probably not getting
security patches. I suggest you
dump all the pages to static ones, so the knowledge doesn't die, and I
can host the static pages on my machine, no problem.

The PKRS MSR is defined as a per-logical-processor register. This
isolates memory access by logical CPU. Unfortunately, the MSR is not
managed by XSAVE. Therefore, tasks must save/restore the MSR value on
context switch.
Define a saved PKRS value in the task struct

Unanticipated access to PMEM by otherwise working kernel code would be
very disruptive to otherwise working systems. Such access could be
through valid uses such as kmap(). In this use case PMEM protections
will require the ability to abandon all protections of a pkey on all
PAGE_KERNEL_PKEY(key) and _PAGE_PKEY(pkey).
Update the protection key documentation to cover pkeys on supervisor
pages. This includes how to reserve a key and set the default
permissions on that key.

The PKRS MSR is not managed by XSAVE. It is preserved through a context
switch but this support leaves exception handling code open to memory
accesses during exceptions.
2 possible places for preserving this state were considered,
irqentry_state_t or pt_regs.[1] pt_regs

Previously if a Protection key fault occurred it indicated something
very wrong because user page mappings are not supposed to be in the
kernel address space.
Now PKey faults may happen on kernel mappings if the feature is enabled.
Remove the warning in the fault path and allow

Protection Keys for Supervisor pages (PKS) enables fast, hardware thread
specific, manipulation of permission restrictions on supervisor page
mappings. It uses the same mechanism of Protection Keys as those on
User mappings but applies that mechanism to supervisor mappings using

Avoid open coding shift and mask operations by defining and using helper

Protection Keys User (PKU) and Protection Keys Supervisor (PKS) work in
similar fashions and can share common defines. Specifically PKS and PKU
each have:
1. A single control register
2. The same number of keys
3. The same number of bits in the register
From: Ira Weiny
Both PKU and PKS update their register values in the same way. They can
therefore share the update code.
Define a helper, update_pkey_val(), which will be used to support both
Protection Key User (PKU) and the new Protection Key for Supervisor
(PKS) in subsequent patches.
