New and rewritten pages
-----------------------
pkey_alloc.2
Dave Hansen [Michael Kerrisk]
New page documenting pkey_alloc(2) and pkey_free(2)
pthread_getattr_default_np.3
Michael Kerrisk
New page documenting pthread_getattr_default_np(3) and pthread_setattr_default_np(3)
strfromd.3
Wainer dos Santos Moschetta
New page documenting strfromd(3), strfromf(3), and strfroml(3)
The ISO/IEC TS 18661-1 specifies the strfrom() class
of functions that convert a float-point value to string.
fuse.4
Keno Fischer [Michael Kerrisk]
New page describing /dev/fuse
This is my writeup of a basic description of /dev/fuse after
playing with it for a few hours today. It is of course woefully
incomplete, and since I neither have a use case nor am working
on this code, I will not be in a position to expand it in the
near future. However, I'm hoping this could still serve as a
handy reference for others looking at this interface.
[mtk: Notwithstanding the incompleteness of this page,
it's a good base for future extension.]

Michael Kerrisk
New page documenting the tmpfs filesystem
pkeys.7
Dave Hansen [Michael Kerrisk]
New page with overview of Memory Protection Keys
random.7
Michael Kerrisk [Theodore Ts'o, Nikos Mavrogiannopoulos, Laurent Georget]

Contains material extracted from getrandom(2) and random(4),
as well as new material.
sock_diag.7

Vince Weaver
Document sample_max_stack and /proc/sys/kernel/perf_event_max_stack

EOVERFLOW error return.
Dave Hansen

bind.2
connect.2
getpeername.2

SEE ALSO: add chmod(1)
chown.2
Michael Kerrisk
SEE ALSO: add chgrp(1) and chown(1)
chroot.2
Michael Kerrisk
SEE ALSO: add chroot(1)

Michael Kerrisk
The CLONE_*_SETTID operations store TID before return to user space
CLONE_PARENT_SETTID and CLONE_CHILD_SETTID store the new
TID before clone() returns to user space
close.2
Michael Kerrisk [Daniel Wagner]
Rework and greatly extend discussion of error handling
Further clarify that an error return should be used only
for diagnostic or remedial purposes.
Michael Kerrisk
Other UNIX implementations also close the FD, even if reporting an error
Looking at some historical source code suggests
that the "close() always closes regardless of error return"
behavior has a long history, predating even POSIX.1-1990.
Michael Kerrisk
Note that future POSIX plans to require that the FD is closed on error
See http://austingroupbugs.net/view.php?id=529#c1200.
Michael Kerrisk
Clarify the variation in EINTR behavior per POSIX and other systems
fallocate.2
Darrick J. Wong
Document behavior with shared blocks
Note that FALLOC_FL_UNSHARE may use CoW to unshare blocks to
guarantee that a disk write won't fail with ENOSPC.
fanotify_mark.2
Heinrich Schuchardt
Mention FAN_Q_OVERFLOW
To receive overflow events it is necessary to set this bit
in fanotify_mark().
fcntl.2
Michael Kerrisk
F_GETPIPE_SZ allocates next power-of-2 multiple of requested size
Add some detail about current implementation, since this helps
the user understand the effect of the user pipe limits added in
Linux 4.5 (described in pipe(7)).
Michael Kerrisk
Add EPERM that occurs for F_SETPIPE_SZ when user pipe limit is reached
fideduperange.2
Darrick J. Wong [Omar Sandoval]
Fix the discussion of maximum sizes
Fix the discussion of the limitations on the dest_count and
src_length parameters to the fideduperange ioctl() to reflect
what's actually in the kernel.
fsync.2
Michael Kerrisk
SEE ALSO: add fileno(3)
fileno(3) is useful if one is combining fflush(3)/fclose(3)
and fsync(2).
Michael Kerrisk

gethostname.2
Michael Kerrisk
SEE ALSO: add hostname(1)

getpriority.2
Michael Kerrisk
Warn that autogrouping voids the effect of 'nice' in many cases
Refer the reader to sched(7) for the details.
Michael Kerrisk
Expand discussion of getpriority() return value
Michael Kerrisk
The nice value supplied to setpriority() is clamped
Note that the nice value supplied to setpriority() is clamped
to the permitted range.
Michael Kerrisk
Improve description of setpriority() return value
getpriority.2
sched.7
Michael Kerrisk
Move nice value details from getpriority(2) to sched(7)
Centralizing these details in sched(7) is more logical.
getrandom.2
random.4
Michael Kerrisk
Consolidate and improve discussion on usage of randomness
Currently, recommendations on how to consume randomness are
spread across both getrandom(2) and random(4) and the general
opinion seems to be that the text in getrandom(2) does a
somewhat better job. Consolidate the discussion to a single
page (getrandom(2)) and address some of the concerns
expressed about the existing text in random(4).
[Some of this text ultimately made its way into the new
random(7) page.]
getrandom.2
Michael Kerrisk
Remove material incorporated into random(7)
Michael Kerrisk
Note advantages of fact that getrandom() doesn't use file descriptors
Michael Kerrisk
Clarify that getrandom() is not "reading" from /dev/{random,urandom}
getrlimit.2
Michael Kerrisk
Refer to sched(7) in discussion of RLIMIT_RTPRIO and RLIMIT_RTTIME
Michael Kerrisk
Describe the range of the RLIMIT_NICE limit
Michael Kerrisk
Refer to sched(7) in the discussion of RLIMIT_NICE
Michael Kerrisk

Warn that autogrouping voids the effect of 'nice' in many cases
Michael Kerrisk
CONFORMING TO: Remove an ancient SVr4 detail on errno values
Michael Kerrisk

raw system call (still) returns 0 on success.
Michael Kerrisk
Clarify the range of the nice value, and note that it is clamped
Michael Kerrisk
Add mention of RLIMIT_NICE
Michael Kerrisk
Move discussion of handling the -1 success return to RETURN VALUE
This detail was rather hidden in NOTES. Also, rework the text
a little.

Remove numeric definitions of PR_FP_MODE_FR and PR_FP_MODE_FRE bits
ptrace.2
Keno Fischer
Document the behavior of PTRACE_SYSEMU stops
Keno Fischer
Expand documentation PTRACE_EVENT_SECCOMP traps
In Linux 4.8, the order of PTRACE_EVENT_SECCOMP and

set_mempolicy.2
Michael Kerrisk
Reformat list of modes
setsid.2
Michael Kerrisk
Improve wording of text on calling setsid() after fork()+_exit()

Michael Kerrisk
Rework formatting of /proc interfaces
Make the information easier to parse by formatting the file
descriptions as hanging lists. No significant content changes.
Nikos Mavrogiannopoulos [Laurent Georget]
Provide a more accurate description of /dev/urandom
This documents the "property" of /dev/urandom of being able to
serve numbers prior to pool being initialized, and removes any
suggested usages of /dev/random which are disputable
(i.e., one-time pad). Document the fact /dev/random is only
suitable for applications which can afford indeterminate delays
since very few applications can do so. Smooth the alarming
language about a theoretical attack, and mention that its
security depends on the cryptographic primitives used by the
kernel, as well as the total entropy gathered.
Michael Kerrisk [Laurent Georget, Theodore Ts'o]
Improve discussion of /dev/urandom, blocking reads, and signals
The text currently states that O_NONBLOCK has no effect for
/dev/urandom, which is true. It also says that reads from
/dev/urandom are nonblocking. This is at the least confusing.
If one attempts large reads (say 10MB) from /dev/urandom
there is an appreciable delay, and interruption by a signal
handler will result in a short read. Amend the text to
reflect this.
elf.5
Mike Frysinger
Add subsection headers at major points
The current pages dumps all the content into one big DESCRIPTION
with no real visual break up between logically independent
sections. Add some subsection headers to make it easier to
read and scan.
Mike Frysinger
Document notes
Document the Elf{32,64}_Nhdr structure, the sections/segments that
contain notes, and how to interpret them. I've been lazy and only
included the GNU extensions here, especially as others are not
defined in the elf.h header file as shipped by glibc.
