HWPOISON: Add new SIGBUS error codes for hardware poison signals
...
Add new SIGBUS codes for reporting machine checks as signals. When
the hardware detects an uncorrected ECC error it can trigger these
signals.
This is needed for telling KVM's qemu about machine checks that happen to
guests, so that it can inject them, but might be also useful for other programs.
I find it useful in my test programs.
This patch merely defines the new types.
- Define two new si_codes for SIGBUS. BUS_MCEERR_AO and BUS_MCEERR_AR
* BUS_MCEERR_AO is for "Action Optional" machine checks, which means that some
corruption has been detected in the background, but nothing has been consumed
so far. The program can ignore those if it wants (but most programs would
already get killed)
* BUS_MCEERR_AR is for "Action Required" machine checks. This happens
when corrupted data is consumed or the application ran into an area
which has been known to be corrupted earlier. These require immediate
action and cannot just returned to. Most programs would kill themselves.
- They report the address of the corruption in the user address space
in si_addr.
- Define a new si_addr_lsb field that reports the extent of the corruption
to user space. That's currently always a (small) page. The user application
cannot tell where in this page the corruption happened.
AK: I plan to write a man page update before anyone asks.
