This patch adds Q_GETNEXTQUOTA, new in Linux 4.6, to
sysdeps/unix/sysv/linux/sys/quota.h.
Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).
* sysdeps/unix/sysv/linux/sys/quota.h [_LINUX_QUOTA_VERSION >= 2]
(Q_GETNEXTQUOTA): New macro.
<sys/personality.h> is out of sync with kernel headers, missing the
UNAME26, FDPIC_FUNCPTRS and PER_LINUX_FDPIC entries. Fix that.
Changelog:
* sysdeps/unix/sysv/linux/sys/personality.h (UNAME26, FDPIC_FUNCPTRS,
PER_LINUX_FDPIC): Add.
This patch updates the glibc headers with the defines MADV_FREE,
IPV6_HDRINCL and EPOLLEXCLUSIVE that are added in Linux 4.5.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
* bits/mman-linux.h [__USE_MISC] (MADV_FREE): New macro.

This patch adds some new header definitions from Linux 4.4:
* MCL_ONFAULT is added to bits/mman.h / bits/mman-linux.h (this was
already done for hppa).
* PTRACE_SECCOMP_GET_FILTER is added to sys/ptrace.h. Along with it,
the older PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, added in Linux
3.11 but missed at the time, are also added.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

Various Linux kernel syscalls have become obsolete over time.
Specifically, the following are obsolete in all kernel versions
supported by glibc, are not present for architectures more recently
added to the kernel, and as such, the wrapper functions for them
should be compat symbols, not in static libc and not available for new
links with shared libc.
* bdflush: in Linux 2.6, does nothing if present.
* create_module get_kernel_syms query_module: Linux 2.4 module
interface, syscalls not present in Linux 2.6.
* uselib: part of the mechanism for loading a.out shared libraries,
irrelevant with ELF.
This patch adds support for syscalls.list to list syscall aliases of
the form NAME@VERSION:OBSOLETED, with SHLIB_COMPAT conditionals being
generated for such aliases. Those five syscalls are then made into
compat symbols (obsoleted in glibc 2.23, so future ports won't have
these symbols at all), with the header <sys/kdaemon.h> declaring
bdflush being removed. When we move to 3.2 as minimum kernel version,
the same can be done for nfsservctl (removed in Linux 3.1) as well.
Tested for x86_64 and x86 (testsuite, as well as checking that the
symbols in question indeed become compat symbols, that they are indeed
omitted from static libc, and that the generated SHLIB_COMPAT
conditionals look right).
[BZ #18472]
* sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Handle entries
for the form NAME@VERSION:OBSOLETED and generate SHLIB_COMPAT
conditionals for them.
* sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Likewise.
* sysdeps/unix/sysv/linux/sys/kdaemon.h: Remove file.
* sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Remove
sys/kdaemon.h.

compat-only syscall, obsoleted in glibc 2.23.

(get_kernel_syms): Likewise.
(query_module): Likewise.
(uselib): Likewise.
* manual/sysinfo.texi (System Parameters): Do not mention bdflush.
This patch updates <sys/ptrace.h> for Linux 4.3, adding
PTRACE_O_SUSPEND_SECCOMP and updating the value of PTRACE_O_MASK.
Some architectures were missing the older PTRACE_O_EXITKILL, so that
was added to the files missing it as well.
Tested for x86_64 (testsuite, and that installed shared libraries are
unchanged by the patch).
* sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h
(PTRACE_O_EXITKILL): New value in enum __ptrace_setoptions.
(PTRACE_O_SUSPEND_SECCOMP): Likewise.
(PTRACE_O_MASK): Update value.
* sysdeps/unix/sysv/linux/ia64/sys/ptrace.h (PTRACE_O_EXITKILL):
New value in enum __ptrace_setoptions.
(PTRACE_O_SUSPEND_SECCOMP): Likewise.

This patch updates installed glibc headers for new definitions from
Linux 4.0 and 4.1 that seem relevant to glibc headers. In addition, I
noticed that PF_IB / AF_IB, added in Linux 3.11, were missing for no
obvious reason, so added those as well.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).
* sysdeps/unix/sysv/linux/bits/in.h (IP_CHECKSUM): New macro.
* sysdeps/unix/sysv/linux/bits/socket.h (PF_IB): Likewise.
(PF_MPLS): Likewise.
(AF_IB): Likewise.
(AF_MPLS): Likewise.
* sysdeps/unix/sysv/linux/sys/mount.h (MS_LAZYTIME): New enum
value and macro.
(MS_RMT_MASK): Include MS_LAZYTIME.
All the other ptrace structures in this file have a __ prefix except this
new one. This in turn causes build problems for most packages that try to
use ptrace such as strace:
gcc -DHAVE_CONFIG_H -I. -I../.. -I../../linux/x86_64 -I../../linux \
-I./linux -Wall -Wwrite-strings -g -O2 -MT process.o -MD -MP \
-MF .deps/process.Tpo -c -o process.o ../../process.c

Since this struct was introduced in glibc-2.18, there shouldn't be any
real regressions with adding the __ prefix.

The event code is PTRACE_EVENT_SECCOMP, not PTRAVE_EVENT_SECCOMP.
This patch fixes the V->C typo. There are no ABI issues since the
number remains the same for the code. Code using the old wrong
name will need to be updated.
[BZ #14809]
* sysdeps/unix/sysv/linux/sys/sysctl.h (_UAPI_LINUX_KERNEL_H)
(_UAPI_LINUX_TYPES_H): Starting with Linux 3.7, the include header
guards are changed. Only define if not yet defined, #undef back
after including linux/sysctl.h if defined here.
(__ptrace_eventcodes): Add new value PTRACE_EVENT_SECCOMP from Linux 3.5.
(__ptrace_setoptions): Add new value PTRACE_O_TRACESECCOMP, adjust PTRACE_O_MASK.
