This driver supports both the platform bus and PCI.
When one or more packets are received, an interrupt happens. The interrupts
are not queued so the driver has to scan all the descriptors in the ring during
the receive process.
-This is based on NAPI so the interrupt handler signals only if there is work to be
-done, and it exits.
+This is based on NAPI so the interrupt handler signals only if there is work

Then the poll method will be scheduled at some future point.
The incoming packets are stored, by the DMA, in a list of pre-allocated socket
buffers in order to avoid the memcpy (Zero-copy).
4.3) Timer-Driver Interrupt
-Instead of having the device that asynchronously notifies the frame receptions, the
-driver configures a timer to generate an interrupt at regular intervals.
-Based on the granularity of the timer, the frames that are received by the device
-will experience different levels of latency. Some NICs have dedicated timer

-channel 2 on STLinux platforms.

detect it at run-time by probing all the 32 addresses.

+The execve system call can grant a newly-started program privileges that
+its parent did not have. The most obvious examples are setuid/setgid
+programs and file capabilities. To prevent the parent program from
+gaining these privileges as well, the kernel and user code must be
+careful to prevent the parent from doing anything that could subvert the
+child. For example:
+
+ - The dynamic loader handles LD_* environment variables differently if
+ a program is setuid.
+
+ - chroot is disallowed to unprivileged processes, since it would allow
+ /etc/passwd to be replaced from the point of view of a process that
+ inherited chroot.
+
+ - The exec code has special handling for ptrace.
+
+These are all ad-hoc fixes. The no_new_privs bit (since Linux 3.5) is a
+new, generic mechanism to make it safe for a process to modify its
+execution environment in a manner that persists across execve. Any task
+can set no_new_privs. Once the bit is set, it is inherited across fork,
+clone, and execve and cannot be unset. With no_new_privs set, execve
+promises not to grant the privilege to do anything that could not have
+been done without the execve call. For example, the setuid and setgid
+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.
+
+There are two main use cases for no_new_privs so far:
+
+ - Filters installed for the seccomp mode 2 sandbox persist across
+ execve and can change the behavior of newly-executed programs.
+ Unprivileged users are therefore only allowed to install such filters
+ if no_new_privs is set.
+
+ - By itself, no_new_privs can be used to reduce the attack surface
+ available to an unprivileged user. If everything running with a
+ given uid has no_new_privs set, then that uid will be unable to
+ escalate its privileges by directly attacking setuid, setgid, and
+ fcap-using binaries; it will need to compromise something without the
+ no_new_privs bit set first.
+
+In the future, other potentially dangerous kernel features could become
+available to unprivileged tasks if no_new_privs is set. In principle,
+several options to unshare(2) and clone(2) would be safe when
+no_new_privs is set, and no_new_privs + chroot is considerable less
+dangerous than chroot by itself.
marked CONFIG_BROKEN), an oops, a hang, data corruption, a real
security issue, or some "oh, that's not good" issue. In short, something
critical.
+ - Serious issues as reported by a user of a distribution kernel may also
+ be considered if they fix a notable performance or interactivity issue.
+ As these fixes are not as obvious and have a higher risk of a subtle
+ regression they should only be submitted by a distribution kernel
+ maintainer and include an addendum linking to a bugzilla entry if it
+ exists and additional information on the user-visible impact.
- New device IDs and quirks are also accepted.
- No "theoretical race condition" issues, unless an explanation of how the
race can be exploited is also provided.

+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.
