[PATCH 1/1] openvswitch: check return value of nla_nest_start

Function nla_nest_start() will return a NULL pointer on error, and its return value should be validated before it is used. However, in function queue_userspace_packet(), its return value is ignored. This may result in NULL dereference when calling nla_nest_end(). This patch fixes the bug.

[PATCH 1/1] NFSv4: check return value of xdr_inline_decode

Function xdr_inline_decode() will return a NULL pointer if the input buffer does not have long enough buffer to decode nbytes of data. However, in function decode_op_map(), the return value of xdr_inline_decode() is not validated before it is used. This patch adds a check to the return value of

[PATCH v2 2/2] tiocsti-restrict : make TIOCSTI ioctl require CAP_SYS_ADMIN

This introduces the tiocsti_restrict sysctl, whose default is controlled via CONFIG_SECURITY_TIOCSTI_RESTRICT. When activated, this control restricts all TIOCSTI ioctl calls from non CAP_SYS_ADMIN users. This patch was inspired from GRKERNSEC_HARDEN_TTY. This patch would have prevented

[PATCH v2 1/2] tiocsti-restrict : Add owner user namespace to tty_struct

This patch adds struct user_namespace *owner_user_ns to the tty_struct. Then it is set to current_user_ns() in the alloc_tty_struct function. This is done to facilitate capability checks against the original user namespace that allocated the tty. E.g. ns_capable(tty->owner_user_ns,CAP_SYS_ADMIN)
