==================== Changes in man-pages-4.15 ====================
New and rewritten pages -----------------------
s390_sthyi.2 QingFeng Hao [Michael Kerrisk] New page for s390-specific s390_sthyi(2)
network_namespaces.7 Michael Kerrisk New page describing network namespaces Based on content moved from namespaces(7)
vsock.7 Stefan Hajnoczi [Jorgen Hansen, Michael Kerrisk] Document the VSOCK socket address family
Newly documented interfaces in existing pages ---------------------------------------------
cgroups.7 Michael Kerrisk [Tejun Heo] Document cgroups v2 "thread mode" Michael Kerrisk [Tejun Heo] Document cgroup v2 delegation via the 'nsdelegate' mount option Michael Kerrisk Document the cgroup.max.depth and cgroup.max.descendants files Michael Kerrisk Document 'release_agent' mount option Michael Kerrisk [Roman Gushchin] Document /sys/kernel/cgroup/delegate Michael Kerrisk [Roman Gushchin] Document /sys/kernel/cgroup/features Michael Kerrisk [Roman Gushchin] Document cgroups v2 cgroup.stat file
Changes to individual pages ---------------------------
fcntl.2 read.2 write.2 NeilBrown Document "Lost locks" as cause for EIO. If an advisory lock is lost, then read/write requests on any affected file descriptor can return EIO - for NFSv4 at least.
mmap.2 John Hubbard [Michael Hocko] MAP_FIXED is no longer discouraged MAP_FIXED has been widely used for a very long time, yet the man page still claims that "the use of this option is discouraged". John Hubbard MAP_FIXED updated documentation -- Expand the documentation to discuss the hazards in enough detail to allow avoiding them.
-- Mention the upcoming MAP_FIXED_SAFE flag.
-- Enhance the alignment requirement slightly.
recvmmsg.2 sendmmsg.2 Nikola Forró Point out that error handling is unreliable
seccomp.2 Michael Kerrisk Clarify that SECCOMP_RET_TRAP SIGSYS signal is thread-directed
capabilities.7 Michael Kerrisk Note which capability sets are affected by SECBIT_NO_SETUID_FIXUP Note explicitly that SECBIT_NO_SETUID_FIXUP is relevant for the permitted, effective, and ambient capability sets. Michael Kerrisk Clarify effect of CAP_SETFCAP Make it clear that CAP_SETFCAP allows setting arbitrary capabilities on a file. Michael Kerrisk Clarify which capability sets are effected by SECBIT_KEEP_CAPS This flag has relevance only for the process permitted and effective sets. Michael Kerrisk Rephrase CAP_SETPCAP description * Mention kernel versions. * Place current kernel behavior first Michael Kerrisk SECBIT_KEEP_CAPS is ignored if SECBIT_NO_SETUID_FIXUP is set Michael Kerrisk Ambient set is also cleared when UIDs are set to nonzero value
cgroups.7 Michael Kerrisk Add a more complete description of cgroup v1 named hierarchies Michael Kerrisk Add a section on unmounting cgroup v1 filesystems Michael Kerrisk Add subsection describing cgroups v2 subtree delegation Michael Kerrisk Mention ENOENT error that can occur when writing to subtree_control file Michael Kerrisk Add list of currently available version 2 controllers Nikolay Borisov Add information about RDMA controller Michael Kerrisk Rewrite the description of cgroup v2 subtree control Michael Kerrisk [Tejun Heo] Note Linux 4.11 changes to cgroup v2 delegation containment rules Michael Kerrisk systemd(1) nowadays automatically mounts the cgroup2 filesystem Michael Kerrisk Clarify that cgroup.controllers is read-only Michael Kerrisk Elaborate a little on problems of splitting threads across cgroups in v1 Michael Kerrisk [Tejun Heo] Tweak the description of delegation of cgroup.subtree_control
sched.7 Michael Kerrisk [Andrea Parri] Correctly describe effect of priority changes for RT threads The placement of a thread in the run queue for its new priority depends on the direction of movement in priority. (This appears to contradict POSIX, except in the case of pthread_setschedprio().)
