Changes to individual pages
---------------------------
+mremap.2
+ Eric B Munson [Michal Hocko]
+ Add note about mremap() with locked areas
+ When mremap() is used to move or expand a mapping that is locked
+ with mlock() or equivalent it will attempt to populate the new
+ area. However, like mmap(MAP_LOCKED), mremap() will not fail if
+ the area cannot be populated. Also like mmap(MAP_LOCKED) this
+ might come as a surprise to users and should be noted.
+open.2
+ Michael Kerrisk [David Drysdale]
+ Remove accidental mention of O_TTY_INIT
+ An earlier edit mentioned O_TTY_INIT as a file creation flag.
+ That's true, according POSIX, but Linux does not implement
+ this flag, so remove mention of it.
+
+pipe.2
+ Michael Kerrisk
+ SEE ALSO: add splice(2)
+
+prctl.2
+ Michael Kerrisk
+ Reorder options alphabetically
+ Employ a pseudo-alphabetical order, ordering options after removal
+ of any "PR_", "PR_SET_", or "PR_GET" prefix.
+ Michael Kerrisk
+ Fix alphabetical misplacements in ERRORS
+
+ptrace.2
+ Tycho Andersen
+ Document PTRACE_O_SUSPEND_SECCOMP flag
+ Michael Kerrisk
+ Document /proc/sys/kernel/yama/ptrace_scope
+ Michael Kerrisk
+ Note that PTRACE_ATTACH cannot be applied to nondumpable processes
+ Michael Kerrisk
+ SEE ALSO: add prctl(2)
+
+reboot.2
+ Casper Ti. Vector
+ 1-argument reboot() is also provided by alternative libc
+
+seccomp.2
+ Michael Kerrisk
+ Describe use of 'instruction_pointer' data field
+ Michael Kerrisk [Kees Cook]
+ Note why all filters in a set are executed even after SECCOMP_RET_KILL
+
+signalfd.2
+ Michael Kerrisk
+ Describe semantics with respect to SCM_RIGHTS
+
+syscalls.2
+ Michael Kerrisk
+ Add mlock(2)
+ Michael Kerrisk
+ Add userfaultfd()
+
+daemon.3
+ Michael Kerrisk [Johannes Stüttgen]
+ Note that daemon() is buggy with respect to controlling tty acquisition
+
+dirfd.3
+ Jonathan Wakely
+ Remove outdated NOTES
+ As stated in the SYNOPSIS, since glibc 2.10 this function is also
+ declared by the relevant X/Open and POSIX macros.
+
+dlopen.3
+ Michael Kerrisk
+ Make it more explicit that LD_BIND_NOW overrides RTLD_LAZY
+ Michael Kerrisk [Florian Weimer]
+ Correct the pathname used in EXAMPLE
+ Quoting Florian:
+
+ This does not work because libm.so can be a linker script:
+
+ handle = dlopen("libm.so", RTLD_LAZY);
+
+ The proper way to do this is to include <gnu/lib-names.h>
+ and use LIBM_SO.
+
+ See https://bugzilla.kernel.org/show_bug.cgi?id=108821
+ Michael Kerrisk
+ Include a shell session showing build/run in EXAMPLE
+ Michael Kerrisk
+ Change arguments to main() to "void" in EXAMPLE
+
+fgetgrent.3
+ Zeng Linggang
+ ATTRIBUTES: Note function that is not thread-safe
+
+fgetpwent.3
+ Zeng Linggang
+ ATTRIBUTES: Note function that is not thread-safe
+
+getauxval.3
+ Michael Kerrisk
+ Add some details for AT_SECURE
+
+getspnam.3
+ Zeng Linggang
+ ATTRIBUTES: Note functions that are/aren't thread-safe
+
+mallinfo.3
+ Zeng Linggang
+ ATTRIBUTES: Note function that is not thread-safe
+
+mallopt.3
+ Carlos O'Donell
+ Document M_ARENA_TEST and M_ARENA_MAX
+
+posix_fallocate.3
+ Michael Kerrisk
+ Clarify text relating to MT-safety
+ Carlos O'Donell
+ Mention glibc emulation caveats
+
+termios.3
+ Olivier TARTROU
+ Add missing details on behaviour of PARMRK
+ For a serial terminal, with a specific configuration, input bytes
+ with value 0377 are passed to the program as two bytes, 0377 0377.
+
+tty_ioctl.4
+ Michael Kerrisk [Peter Hurley]
+ Note that TIOCTTYGSTRUCT went away in Linux 2.5.67
+
+core.5
+ Ross Zwisler
+ Add info about DAX coredump filtering flags
+ Kernel 4.4 added two new core dump filtering flags,
+ MMF_DUMP_DAX_PRIVATE and MMF_DUMP_DAX_SHARED.
+
+ These flags allow us to explicitly filter DAX mappings.
+ This is desirable because DAX mappings, like hugetlb
+ mappings, have the potential to be very large.
+
+nsswitch.conf.5
+ Nikola Forró
+ Add list of files being read when "files" service is used
+ This is not mentioned anywhere. Users can assume that the file
+ being read is something like /etc/$DATABASE, but that's not
+ always the case. It's better to explicitly specify which
+ file is read for each respective database. The list of
+ files was acquired from glibc source code.
+
+proc.5
+ Heinrich Schuchardt [Michael Kerrisk]
+ Add details for threads-max
+ Add detail information for threads-max.
+ The checks for minimum and maximum values exist since kernel 4.1.
+ https://lkml.org/lkml/2015/3/15/96
+ Heinrich Schuchardt
+ /proc/sys: Describe whitespace characters
+ Michael Kerrisk
+ Document 'CapAmb' in /proc/PID/status
+ Michael Kerrisk
+ Add reference to ptrace(2) for /proc/sys/kernel/yama/ptrace_scope
+
+aio.7
+ Michael Kerrisk [Meikun Wang]
+ Add missing include file, <fcntl.h>, to example program
+
+mq_overview.7
+ Michael Kerrisk [Arto Bendiken]
+ Document QSIZE bug that appeared in 3.5 and was fixed in 4.2
+
+path_resolution.7
+ Michael Kerrisk
+ Clarify recursive resolution of symlinks and note limits
+
+pipe.7
+ Michael Kerrisk
+ SEE ALSO: add splice(2)
+
+rtld-audit.7
+ Namhyung Kim
+ Fix (typo) error in la_pltenter() description
+ s/la_pltenter()/la_pltexit()/
+
+ la_pltenter() is called regardless of the value of
+ framesizep but la_pltexit() is called only if la_pltenter()
+ returns with non-zero framesizep set. I spent long time to
+ figure out why la_pltexit() is not called at all.
+
+signal.7
+ Michael Kerrisk [Michael Hocko]
+ Note async-signal-safe functions added by POSIX.1-2008 TC1
+
+tcp.7
+ Daniel Borkmann [Michael Kerrisk]
+ Improve paragraphs on tcp_ecn and add tcp_ecn_fallback bullet
+ Improve description of tcp_ecn, fix the RFC number and it's
+ not a boolean anymore since long time, and add a description
+ for tcp_ecn_fallback.
+
+ See also kernel doc under Documentation/networking/ip-sysctl.txt
+ on tcp_ecn and tcp_ecn_fallback.
+
+ld.so.8
+ Michael Kerrisk
+ LD_POINTER_GUARD has been removed in glibc 2.23
+ Michael Kerrisk
+ Describe secure-execution mode
+ Michael Kerrisk [Maria Guseva]
+ Replace mentions of set-UID/set-GID programs with secure-execution mode
+ Inspired by a patch from Maria Guseva.
+ Maria Guseva [Silvan Jegen]
+ LD_DEBUG is effective in secure-execution mode if /etc/suid-debug exists
