+Global changes
+--------------
Changes to individual pages
---------------------------
-bind.2
- Michael Kerrisk
- ERRORS: Add EADDRINUSE for ephemeral port range exhaustion
-
-chown.2
- Michael Kerrisk
- NOTES: Add some subheadings
-
-connect.2
- Michael Kerrisk [William Morriss]
- ERRORS: Add EADDRNOTAVAIL for ephemeral port range exhaustion
- Verified from testing and the kernel source.
- See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=745775
- Michael Kerrisk
- Remove mention of ip_local_port_range under EAGAIN error
- Man-pages commit ac7477eb7a8 added EADDRNOTAVAIL as the correct
- error for ephemeral port range exhaustion. However, that error
- was also incorrectly described under the EAGAIN entry. So,
- remove that text under EAGAIN.
-
-create_module.2
-delete_module.2
-init_module.2
-query_module.2
- Michael Kerrisk [Lucas De Marchi]
- Clarify glibc header file declaration/ABI wrapper details
- create_module(), delete_module(), init_module(), and
- query_module() are not declared in header files, but
- through an accident of history glibc provides an ABI
- for them that it continues to maintain, for
- compatibility reasons.
-
-execve.2
- Michael Kerrisk [Steven Stewart-Gallus]
- Note SIGKILL case when execve() fails beyond the point of no return
- Michael Kerrisk
- NOTES: Add a subheading and reorder paragraphs
-
-fanotify_init.2

- Document range of permitted flags for event_f_flags
- With a new patch included in the mm tree, event_f_flags is
- checked for allowable values.
-
-fcntl.2
- Michael Kerrisk
- Add "file locking" subheading under NOTES
-
-fork.2
- Michael Kerrisk
- ERRORS: SCHED_DEADLINE tasks can fail with EAGAIN
- SCHED_DEADLINE tasks can fail with EAGAIN unless the
- reset-on-fork flag is set.
-
-futex.2
- Michael Kerrisk
- Note that there is no glibc wrapper
-
-getpriority.2
- Rasmus Villemoes
- Fix prototypes for getpriority() and setpriority()
- The who argument has type id_t (which happens to be u32 on linux).
-
-get_robust_list.2
- Rasmus Villemoes
- Add <sys/types.h> to synopsis of get_robust_list()
- If one were to implement wrappers for [gs]et_robust_list() using the
- given prototypes, one would also have to include sys/types.h to get
- a definition of size_t.
-
-getrusage.2
- Michael Kerrisk [Bill Allombert]
- _GNU_SOURCE must be defined to obtain RUSAGE_THREAD definition
- See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746569

-link.2
-open.2
- Andy Lutomirski [Michael Kerrisk]

-
-listen.2
- Michael Kerrisk
- ERRORS: Add EADDRINUSE for ephemeral port range exhaustion
-
-mbind.2
- Rasmus Villemoes
- Fix prototype for mbind(2)
- The nmask argument is const. The return type in numaif.h is long.
- (Well, at least <numaif.h> says nmask is const. The current kernel
- does not define it as a const argument, but sys_mbind() only
- passes it to get_nodes(), which does treat it as const.)
-
-msgop.2
- Davidlohr Bueso [Michael Kerrisk]
- Enhance description of "full queue" criteria
-
-poll.2
- Rasmus Villemoes
- Add <signal.h> to synopsis for ppoll()

- type (sigset_t) of the mask argument to ppoll().
-
-readlink.2
- Rasmus Villemoes
- Fix return type of readlinkat()
-
-recv.2
- Michael Kerrisk
- Clarify details of msg_name and msg_namelen fields
-
-recvmmsg.2

- Describe timeout bug
- See FIXME https://bugzilla.kernel.org/show_bug.cgi?id=75371
- and http://thread.gmane.org/gmane.linux.man/5677
-
-remap_file_pages.2
- Andy Lutomirski [Christoph Hellwig, Andy Lutomirski]
- remap_file_pages() has no benefit for real files
- Linux commit 3ee6dafc677a68e461a7ddafc94a580ebab80735 caused
- remap_file_pages to be emulated when used on real file.
-
-sched_get_priority_max.2

- did not originate in MS DOS, but in Lattice C on AmigaDOS.
-
- Here is a patch against the git master HEAD to fix that, and add
- some more historical information. To provide some background and
- allow you to more easily verify the correctness of the patch, i'm
- appending my mail to <misc@openbsd.org>, where i'm giving some
- more details about the history and pointing to some primary
- sources. That mail also contains the (similar, but shorter)
- patch i just committed to the OpenBSD manual page.

- Michael Kerrisk
- sched_setattr(2) can also be used to set 'nice' value

- well, rewrite the text in a more generic way.

- Note that these APIs are a superset of sched_setscheduler(2)
- and sched_getscheduler(2).
- Michael Kerrisk

- All of the removed text is in sched_setscheduler(2) and
