When build_cpu_topo() encounters offline/absent CPUs,
it fails to find any sysfs entries and returns failure.

By moving those functions into fs/posix_acl.c and fs/richacl.c, the
ifdefs can be moved into include/linux/posix_acl.h and
include/linux/richacl.h. This may be seen as a small improvement.

Hello,
This patch series addesses Coverity ID 1091172, which reports the
use of a freed pointer. udc_free_dma_chain() function was rewritten
in order to fix this issue.
Unnecessary 'ret_val' variable was removed and the function prototype
was modified.

Doing a chmod() sets the file mode, which includes the file permission
bits. When a file has a richacl, the permissions that the richacl
grants need to be limited to what the new file permission bits allow.
This is done by setting the file masks in the richacl to what the file
permission bits map

This patch adds "tty-index" field to /proc/PID/fdinfo/N if N
specifies /dev/ptmx. The field shows the index of associative

Though a minor number is given for each pts instance, ptmx is not.
It means there is no way in user-space to know the association between

This patch series follows on from my recent Xen series [1], to provide
support in privcmd for de-privileging of device emulators.
[1] https://lists.xen.org/archives/html/xen-devel/2017-01/msg02558.html
Paul Durrant (3):
xen/privcmd: return -ENOTTY for unimplemented IOCTLs
xen/privcmd: Add IOC
The purpose if this ioctl is to allow a user of privcmd to restrict its
operation such that it will no longer service arbitrary hypercalls via
IOCTL_PRIVCMD_HYPERCALL, and will check for a matching domid when
servicing IOCTL_PRIVCMD_DM_OP. The aim of this is to limit the attack
surface for a compro
The code sets the default return code to -ENOSYS but then overrides this
to -EINVAL in the switch() statement's default case, which is clearly
silly.
This patch removes the override and sets the default return code to
-ENOTTY, which is the conventional return for an unimplemented ioctl.
Signed-of
Recently a new dm_op[1] hypercall was added to Xen to provide a mechanism
for restricting device emulators (such as QEMU) to a limited set of
hypervisor operations, and being able to audit those operations in the
kernel of the domain in which they run.
This patch adds IOCTL_PRIVCMD_DM_OP as gatewa
