Description:
This allows the user to examine and adjust the criteria by which
mtd returns -EUCLEAN from mtd_read(). If the maximum number of
bit errors that were corrected on any single region comprising
an ecc step (as reported by the driver) equals or exceeds this
value, -EUCLEAN is returned. Otherwise, absent an error, 0 is
returned. Higher layers (e.g., UBI) use this return code as an
indication that an erase block may be degrading and should be
scrutinized as a candidate for being marked as bad.
mtd returns -EUCLEAN from mtd_read() and mtd_read_oob(). If the
maximum number of bit errors that were corrected on any single
region comprising an ecc step (as reported by the driver) equals
or exceeds this value, -EUCLEAN is returned. Otherwise, absent
an error, 0 is returned. Higher layers (e.g., UBI) use this
return code as an indication that an erase block may be
degrading and should be scrutinized as a candidate for being
marked as bad.
The initial value may be specified by the flash device driver.
If not, then the default value is ecc_strength.

block degradation, but high enough to avoid the consequences of
a persistent return value of -EUCLEAN on devices where sticky
bitflips occur. Note that if bitflip_threshold exceeds
ecc_strength, -EUCLEAN is never returned by mtd_read().
ecc_strength, -EUCLEAN is never returned by the read operations.
Conversely, if bitflip_threshold is zero, -EUCLEAN is always
returned, absent a hard error.

Documentation/prctl/no_new_privs.txt
View File

@ -25,6 +25,13 @@ bits will no longer change the uid or gid; file capabilities will not
add to the permitted set, and LSMs will not relax constraints after
execve.
To set no_new_privs, use prctl(PR_SET_NO_NEW_PRIVS, 1, 0, 0, 0).
Be careful, though: LSMs might also not tighten constraints on exec
in no_new_privs mode. (This means that setting up a general-purpose
service launcher to set no_new_privs before execing daemons may
interfere with LSM-based sandboxing.)
Note that no_new_privs does not prevent privilege changes that do not
involve execve. An appropriately privileged task can still call
setuid(2) and receive SCM_RIGHTS datagrams.

4.75 KVM_IRQFD
Capability: KVM_CAP_IRQFD
Architectures: x86
Type: vm ioctl
Parameters: struct kvm_irqfd (in)
Returns: 0 on success, -1 on error
Allows setting an eventfd to directly trigger a guest interrupt.
kvm_irqfd.fd specifies the file descriptor to use as the eventfd and
kvm_irqfd.gsi specifies the irqchip pin toggled by this event. When
an event is tiggered on the eventfd, an interrupt is injected into
the guest using the specified gsi pin. The irqfd is removed using
the KVM_IRQFD_FLAG_DEASSIGN flag, specifying both kvm_irqfd.fd
and kvm_irqfd.gsi.
