Global changes
|
||||
--------------
|
||||
|
||||
|
||||
Changes to individual pages
|
||||
---------------------------
|
||||
|
||||
ldd.1
|
||||
Michael Kerrisk
|
||||
'objdump -p prog | grep NEEDED' doesn't give quite same info as 'ldd'
|
||||
|
||||
chmod.2
|
||||
Michael Kerrisk
|
||||
Put fchmod() feature test macro requirements in a more readable format
|
||||
Michael Kerrisk
|
||||
Note glibc 2.24 feature test macro requirements changes for fchmod()
|
||||
|
||||
chown.2
|
||||
Michael Kerrisk
|
||||
When file owner or group is changed, file capabilities are cleared
|
||||
Michael Kerrisk
|
||||
Changes to file owner by root also clear set-UID and set-GID bits
|
||||
|
||||
clone.2
|
||||
Michael Kerrisk
|
||||
Update BUGS to reflect fact that PID caching was removed in glibc 2.25
|
||||
|
||||
epoll_wait.2
|
||||
Michael Kerrisk
|
||||
Clarify semantics of returned 'data' field
|
||||
The returned 'data' is the 'data' most recently set via
|
||||
epoll_ctl().
|
||||
|
||||
get_mempolicy.2
|
||||
Michael Kerrisk [Nadav Har'El, Andi Kleen]
|
||||
SYNOPSIS: fix return type of get_mempolicy()
|
||||
See https://bugzilla.kernel.org/show_bug.cgi?id=97051
|
||||
|
||||
getpid.2
|
||||
Carlos O'Donell, Michael Kerrisk
|
||||
Note that PID caching is removed as of glibc 2.25
|
||||
Since glibc 2.25 the PID cache is removed.
|
||||
|
||||
Rationale given in the release notes:
|
||||
https://sourceware.org/glibc/wiki/Release/2.25#pid_cache_removal
|
||||
|
||||
ioctl.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add ioctl_getfsmap(2)
|
||||
|
||||
ioctl_getfsmap.2
|
||||
Michael Kerrisk
|
||||
Fix ordering of sections
|
||||
Michael Kerrisk
|
||||
Add VERSIONS section
|
||||
|
||||
ioctl_getfsmap.2
|
||||
Darrick J. Wong
|
||||
Document the GETFSMAP ioctl
|
||||
Document the new GETFSMAP ioctl that returns the physical layout of a
|
||||
(disk-based) filesystem.
|
||||
Michael Kerrisk
|
||||
ERRORS: order alphabetically
|
||||
|
||||
madvise.2
|
||||
Michael Kerrisk
|
||||
Remove bogus text re POSIX_MADV_NOREUSE
|
||||
There is a POSIX_FADV_NOREUSE for posix_fadvise(),
|
||||
but no POSIX_MADV_NOREUSE for any API in POSIX.
|
||||
|
||||
membarrier.2
|
||||
Michael Kerrisk
|
||||
Add ENOSYS error for 'nohz_full' CPU setting
|
||||
|
||||
mount.2
|
||||
NeilBrown
|
||||
Revise description of MS_REMOUNT | MS_BIND
|
||||
MS_REMOUNT|MS_BIND affects all per-mount-point
|
||||
flag. MS_RDONLY is only special because it,
|
||||
uniquely, is both a per-mount-point flag *and* a
|
||||
per-filesystem flag.
|
||||
|
||||
So the sections of per-mount-point flags and
|
||||
MS_REMOUNT can usefully be clarified.
|
||||
|
||||
open.2
|
||||
Michael Kerrisk
|
||||
Note some further advantages of the *at() APIs
|
||||
|
||||
pipe.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add tee(2) and vmsplice(2)
|
||||
|
||||
readv.2
|
||||
Michael Kerrisk
|
||||
glibc 2.26 adds library support for preadv2() and pwritev2()
|
||||
|
||||
sched_setaffinity.2
|
||||
Michael Kerrisk
|
||||
Mention cpuset cgroups as a cause of EINVAL error
|
||||
|
||||
seccomp.2
|
||||
Mike Frysinger
|
||||
Expand SECCOMP_RET_KILL documentation
|
||||
|
||||
sigaction.2
|
||||
Michael Kerrisk
|
||||
Note feature test macro requirements for 'si_code' constants
|
||||
Michael Kerrisk
|
||||
Add a subheading for the description of 'si_code'
|
||||
Michael Kerrisk
|
||||
TRAP_BRANCH and TRAP_HWBKPT are present only on IA64
|
||||
|
||||
sigaltstack.2
|
||||
Michael Kerrisk
|
||||
Note that specifying SS_ONSTACK in ss.ss_flags decreases portability
|
||||
In the Illumos source (which presumably mirrors its Solaris
|
||||
ancestry), there is this check in the sigaltstack()
|
||||
implementation:
|
||||
|
||||
if (ss.ss_flags & ~SS_DISABLE)
|
||||
return (set_errno(EINVAL));
|
||||
|
||||
And in the FreeBSD source we find similar:
|
||||
|
||||
if ((ss->ss_flags & ~SS_DISABLE) != 0)
|
||||
return (EINVAL);
|
||||
Michael Kerrisk
|
||||
Note buggy addition of ss.ss_flags==SS_ONSTACK
|
||||
Note buggy addition of ss.ss_flags==SS_ONSTACK as a synonym
|
||||
for ss_flags==0. No other implemenation does this, AFAIK.
|
||||
And it was not needed :-(.
|
||||
Michael Kerrisk
|
||||
Specifying 'ss' returns the current settings without changing them
|
||||
Michael Kerrisk
|
||||
Give 'oss' argument a more meaningful name: 'old_ss'
|
||||
Michael Kerrisk
|
||||
Some minor reworking of the text
|
||||
Michael Kerrisk
|
||||
ERRORS: update description of EINVAL error
|
||||
|
||||
splice.2
|
||||
tee.2
|
||||
vmsplice.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add pipe(7)
|
||||
|
||||
splice.2
|
||||
Michael Kerrisk
|
||||
ERRORS: split EINVAL error cases
|
||||
Michael Kerrisk
|
||||
ERRORS: add EINVAL for case where both descriptors refer to same pipe
|
||||
|
||||
timer_create.2
|
||||
Michael Kerrisk
|
||||
Document the CONFIG_POSIX_TIMERS option added in Linux 4.10
|
||||
|
||||
wait.2
|
||||
Michael Kerrisk
|
||||
Note glibc 2.26 changes to feature test macro requirements for waitid()
|
||||
|
||||
acosh.3
|
||||
asinh.3
|
||||
atanh.3

|
||||
|
||||
[mtk: confirmed from review of draft of C90 standard]
|
||||
|
||||
bsd_signal.3
|
||||
Michael Kerrisk
|
||||
Note feature test macro requirements changes for glibc 2.26
|
||||
|
||||
dl_iterate_phdr.3
|
||||
Michael Kerrisk
|
||||
dl_iterate_phdr() shows the order in which objects were loaded
|
||||
dl_iterate_phdr() tells us not just which objects are
|
||||
loaded, but also the order in which they are loaded
|
||||
(the "link-map order"). Since the order is relevant for
|
||||
understanding symbol resolution, give the reader this clue.
|
||||
Michael Kerrisk
|
||||
Expand the code example, and show sample output
|
||||
Michael Kerrisk
|
||||
List values for the 'p_type' field

|
||||

|
||||
|
||||
flockfile.3
|
||||
Michael Kerrisk
|
||||
Note glibc 2.24 feature test macro requirement changes
|
||||
|
||||

|
||||
Michael Kerrisk
|
||||

|
||||
Michael Kerrisk
|
||||

|
||||
The existing description was not accurate, and lacked details.
|
||||
|
||||
ftw.3
|
||||
Michael Kerrisk
|
||||
BUGS: document a probable glibc regression in FTW_SLN case
|
||||
See https://bugzilla.redhat.com/show_bug.cgi?id=1422736
|
||||
and http://austingroupbugs.net/view.php?id=1121.
|
||||
|
||||
getaddrinfo.3
|
||||
Quentin Rameau
|
||||
Fix _POSIX_C_SOURCE value for getaddrinfo()
|
||||
The correct _POSIX_C_SOURCE value is 200112L, not 201112L in features.h.
|
||||
|
||||
getcontext.3
|
||||
Carlos O'Donell
|
||||
Exemplar structure should use 'ucontext_t'.
|
||||
In glibc we just finished a round of purging 'struct ucontext'
|
||||
which is not in the POSIX reserved namespace of *_t tags. This has
|
||||
some consequences to applications using the non-standard struct
|
||||
ucontext:
|
||||
https://sourceware.org/glibc/wiki/Release/2.26#Removal_of_.27struct_ucontext.27
|
||||
but it also fixes a namespace conformance issue which is always a
|
||||
longterm pain for large portable programs.
|
||||
|
||||
It was noted by Peter Maydell
|
||||
(https://sourceware.org/bugzilla/show_bug.cgi?id=21457) that the
|
||||
linux man pages still had references to 'struct ucontext' but only
|
||||
in the form of an exemplar structure.
|
||||
|
||||
The patch fixes the exemplar to match what is in glibc
|
||||
and therefore it won't ever suggest users can use 'struct
|
||||
ucontext'.
|
||||
|
||||
getgrent.3
|
||||
Michael Kerrisk
|
||||
Note glibc 2.22 changes for feature test macro requirements
|
||||
|
||||
grantpt.3
|
||||
ptsname.3
|
||||
unlockpt.3
|
||||
Ferdinand Thiessen [Michael Kerrisk]
|
||||
Update feature test macro-requirements for glibc 2.24
|
||||
|
||||
if_nametoindex.3
|
||||
Douglas Caetano dos Santos
|
||||
Add ENODEV error for if_nametoindex()
|
||||
Checked against glibc and kernel code: when given name isn't
|
||||
a valid interface, kernel returns ENODEV and glibc just
|
||||
forwards it.
|
||||
|
||||
malloc.3
|
||||
Michael Kerrisk
|
||||
Document the reallocarray() added in glibc 2.26
|
||||
|
||||
nl_langinfo.3
|
||||
Michael Kerrisk
|
||||
Note feature test macro requirements for nl_langinfo_l()
|
||||
|
||||
posix_madvise.3
|
||||
Dr. Tobias Quathamer
|
||||
Remove paragraph about POSIX_FADV_NOREUSE
|
||||
POSIX_FADV_NOREUSE is documented for posix_fadvise, and a
|
||||
corresponding POSIX_MADV_NOREUSE flag is not specified by POSIX.
|
||||
|
||||
Thanks to Marc Lehmann <debian-reportbug@plan9.de>
|
||||
See https://bugs.debian.org/865699
|
||||
|
||||
ptsname.3
|
||||
Michael Kerrisk [Arjun Shankar]
|
||||
Since glibc 2.26, ptsname_r() no longer gives EINVAL for buf==NULL
|
||||
|
||||
rand.3
|
||||
Michael Kerrisk
|
||||
Note glibc 2.24 feature test macro requirement changes for rand_r()

||||
Mention 0X prefix
|
||||
The prefix 0x may be capitalized as 0X.
|
||||
|
||||
See ISO/IEC 9899:1999.
|
||||
|
||||
sysconf.3
|
||||
Michael Kerrisk [Pavel Tikhomirov]
|
||||
Rework RETURN VALUE description to add more detail
|
||||
Make the discussion clearer, and add a few details.
|
||||
Also, fix the problem report from Pavel Tikhomirov
|
||||
who noted that the man page falsely said that errno
|
||||
is not changed on a successful return.
|
||||
|
||||

|
||||
team and Stephen Gallagher.
|
||||

Mention signal.h header file
|
||||
|
||||
signal.7
|
||||
Michael Kerrisk [lilydjwg]
|
||||
Since Linux 3.8, read(2) on an inotify FD is restartable with SA_RESTART
|
||||
See https://bugzilla.kernel.org/show_bug.cgi?id=195711
|
||||
Michael Kerrisk
|
||||
read() from an inotify FD is no longer interrupted by a stop signal
|
||||
(Change was in Linux 3.8.)
|
||||
|
||||
tcp.7
|
||||
Michael Kerrisk
|
||||
Document value '2' for tcp_timestamps
|
||||
Since Linux 4.10, the value '2' is meaningful for tcp_timestamps
|
||||
Ruben Kerkhof
|
||||
Change default value of tcp_frto
|
||||
The default changed in c96fd3d461fa495400df24be3b3b66f0e0b152f9
|
||||
(Linux 2.6.24).
|
||||
|
||||
ld.so.8
|
||||
Michael Kerrisk
|
||||
Greatly expand the explanation of LD_DYNAMIC_WEAK
|
||||
Carlos O'Donell
|
||||
Expand DT_RUNPATH details.
|
||||
ld.so.8: Expand DT_RUNPATH details.
|
||||
|
||||
Every 3 years we get asked why DT_RUNPATH doesn't work like DT_RPATH.
|
||||
The most recent question was here:
|
||||
https://www.sourceware.org/ml/libc-help/2017-06/msg00013.html
|
||||
|
||||
We need to expand the description of DT_RUNPATH to cover this
|
||||
situation and explain that the DT_RUNPATH entries apply only to the
|
||||
immediate DT_NEEDED, not that of another, say dlopen'd child object.
|
||||
Michael Kerrisk
|
||||
Since glibc 2.2.5, LD_PROFILE is ignored in secure-execution mode
|
||||
Michael Kerrisk
|
||||
Make notes on secure-execute mode more prominent
|
||||
Place each note on secure-execution mode in a separate
|
||||
paragraph, to make it more obvious.
|
||||
Michael Kerrisk
|
||||
Note that libraries in standard directories are not normally set-UID
|
||||
In secure mode, LD_PRELOAD loads only libraries from standard
|
||||
directories that are marked set-UID. Note that it is unusual for
|
||||
a library to be marked in this way.
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add elf(5)
|
||||
Michael Kerrisk
|
||||
Note version where secure-execution started ignoring LD_USE_LOAD_BIAS
|
||||
Michael Kerrisk
|
||||
Correct glibc version that ignores LD_SHOW_AUXV in secure-execution mode
|
||||
Ignored since 2.3.4 (not 2.3.5).
|
||||
Michael Kerrisk
|
||||
Rewrite LD_DEBUG_OUTPUT description and note that .PID is appended

|
||||
Document the /proc/[pid]/ns/pid_for_children file
|
||||
|
||||
|
||||
Changes to individual pages
|
||||
---------------------------
|
||||
|
||||
ldd.1
|
||||
Michael Kerrisk
|
||||
'objdump -p prog | grep NEEDED' doesn't give quite same info as 'ldd'
|
||||
|
||||
chmod.2
|
||||
Michael Kerrisk
|
||||
Put fchmod() feature test macro requirements in a more readable format
|
||||
Michael Kerrisk
|
||||
Note glibc 2.24 feature test macro requirements changes for fchmod()
|
||||
|
||||
chown.2
|
||||
Michael Kerrisk
|
||||
When file owner or group is changed, file capabilities are cleared
|
||||
Michael Kerrisk
|
||||
Changes to file owner by root also clear set-UID and set-GID bits
|
||||
|
||||
clone.2
|
||||
Michael Kerrisk
|
||||
Update BUGS to reflect fact that PID caching was removed in glibc 2.25
|
||||
|
||||
epoll_wait.2
|
||||
Michael Kerrisk
|
||||
Clarify semantics of returned 'data' field
|
||||
The returned 'data' is the 'data' most recently set via
|
||||
epoll_ctl().
|
||||
|
||||
get_mempolicy.2
|
||||
Michael Kerrisk [Nadav Har'El, Andi Kleen]
|
||||
SYNOPSIS: fix return type of get_mempolicy()
|
||||
See https://bugzilla.kernel.org/show_bug.cgi?id=97051
|
||||
|
||||
getpid.2
|
||||
Carlos O'Donell, Michael Kerrisk
|
||||
Note that PID caching is removed as of glibc 2.25
|
||||
Since glibc 2.25 the PID cache is removed.
|
||||
|
||||
Rationale given in the release notes:
|
||||
https://sourceware.org/glibc/wiki/Release/2.25#pid_cache_removal
|
||||
|
||||
ioctl.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add ioctl_getfsmap(2)
|
||||
|
||||
ioctl_getfsmap.2
|
||||
Michael Kerrisk
|
||||
Fix ordering of sections
|
||||
Michael Kerrisk
|
||||
Add VERSIONS section
|
||||
|
||||
ioctl_getfsmap.2
|
||||
Darrick J. Wong
|
||||
Document the GETFSMAP ioctl
|
||||
Document the new GETFSMAP ioctl that returns the physical layout of a
|
||||
(disk-based) filesystem.
|
||||
Michael Kerrisk
|
||||
ERRORS: order alphabetically
|
||||
|
||||
madvise.2
|
||||
Michael Kerrisk
|
||||
Remove bogus text re POSIX_MADV_NOREUSE
|
||||
There is a POSIX_FADV_NOREUSE for posix_fadvise(),
|
||||
but no POSIX_MADV_NOREUSE for any API in POSIX.
|
||||
|
||||
membarrier.2
|
||||
Michael Kerrisk
|
||||
Add ENOSYS error for 'nohz_full' CPU setting
|
||||
|
||||
mount.2
|
||||
NeilBrown
|
||||
Revise description of MS_REMOUNT | MS_BIND
|
||||
MS_REMOUNT|MS_BIND affects all per-mount-point
|
||||
flag. MS_RDONLY is only special because it,
|
||||
uniquely, is both a per-mount-point flag *and* a
|
||||
per-filesystem flag.
|
||||
|
||||
So the sections of per-mount-point flags and
|
||||
MS_REMOUNT can usefully be clarified.
|
||||
|
||||
open.2
|
||||
Michael Kerrisk
|
||||
Note some further advantages of the *at() APIs
|
||||
|
||||
pipe.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add tee(2) and vmsplice(2)
|
||||
|
||||
readv.2
|
||||
Michael Kerrisk
|
||||
glibc 2.26 adds library support for preadv2() and pwritev2()
|
||||
|
||||
sched_setaffinity.2
|
||||
Michael Kerrisk
|
||||
Mention cpuset cgroups as a cause of EINVAL error
|
||||
|
||||
seccomp.2
|
||||
Mike Frysinger
|
||||
Expand SECCOMP_RET_KILL documentation
|
||||
|
||||
sigaction.2
|
||||
Michael Kerrisk
|
||||
Note feature test macro requirements for 'si_code' constants
|
||||
Michael Kerrisk
|
||||
Add a subheading for the description of 'si_code'
|
||||
Michael Kerrisk
|
||||
TRAP_BRANCH and TRAP_HWBKPT are present only on IA64
|
||||
|
||||
sigaltstack.2
|
||||
Michael Kerrisk
|
||||
Note that specifying SS_ONSTACK in ss.ss_flags decreases portability
|
||||
In the Illumos source (which presumably mirrors its Solaris
|
||||
ancestry), there is this check in the sigaltstack()
|
||||
implementation:
|
||||
|
||||
if (ss.ss_flags & ~SS_DISABLE)
|
||||
return (set_errno(EINVAL));
|
||||
|
||||
And in the FreeBSD source we find similar:
|
||||
|
||||
if ((ss->ss_flags & ~SS_DISABLE) != 0)
|
||||
return (EINVAL);
|
||||
Michael Kerrisk
|
||||
Note buggy addition of ss.ss_flags==SS_ONSTACK
|
||||
Note buggy addition of ss.ss_flags==SS_ONSTACK as a synonym
|
||||
for ss_flags==0. No other implemenation does this, AFAIK.
|
||||
And it was not needed :-(.
|
||||
Michael Kerrisk
|
||||
Specifying 'ss' returns the current settings without changing them
|
||||
Michael Kerrisk
|
||||
Give 'oss' argument a more meaningful name: 'old_ss'
|
||||
Michael Kerrisk
|
||||
Some minor reworking of the text
|
||||
Michael Kerrisk
|
||||
ERRORS: update description of EINVAL error
|
||||
|
||||
splice.2
|
||||
tee.2
|
||||
vmsplice.2
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add pipe(7)
|
||||
|
||||
splice.2
|
||||
Michael Kerrisk
|
||||
ERRORS: split EINVAL error cases
|
||||
Michael Kerrisk
|
||||
ERRORS: add EINVAL for case where both descriptors refer to same pipe
|
||||
|
||||
timer_create.2
|
||||
Michael Kerrisk
|
||||
Document the CONFIG_POSIX_TIMERS option added in Linux 4.10
|
||||
|
||||
wait.2
|
||||
Michael Kerrisk
|
||||
Note glibc 2.26 changes to feature test macro requirements for waitid()
|
||||
|
||||
acosh.3
|
||||
asinh.3
|
||||
atanh.3

|
||||
|
||||
[mtk: confirmed from review of draft of C90 standard]
|
||||
|
||||
bsd_signal.3
|
||||
Michael Kerrisk
|
||||
Note feature test macro requirements changes for glibc 2.26
|
||||
|
||||
dl_iterate_phdr.3
|
||||
Michael Kerrisk
|
||||
dl_iterate_phdr() shows the order in which objects were loaded
|
||||
dl_iterate_phdr() tells us not just which objects are
|
||||
loaded, but also the order in which they are loaded
|
||||
(the "link-map order"). Since the order is relevant for
|
||||
understanding symbol resolution, give the reader this clue.
|
||||
Michael Kerrisk
|
||||
Expand the code example, and show sample output
|
||||
Michael Kerrisk
|
||||
List values for the 'p_type' field
|
||||

|
||||
|
||||
flockfile.3
|
||||
Michael Kerrisk
|
||||
Note glibc 2.24 feature test macro requirement changes
|
||||
|
||||

|
||||
Michael Kerrisk
|
||||

|
||||
Michael Kerrisk
|
||||

|
||||
|
||||
ftw.3
|
||||
Michael Kerrisk
|
||||
BUGS: document a probable glibc regression in FTW_SLN case
|
||||
See https://bugzilla.redhat.com/show_bug.cgi?id=1422736
|
||||
and http://austingroupbugs.net/view.php?id=1121.
|
||||
|
||||
getaddrinfo.3
|
||||
Quentin Rameau
|
||||
Fix _POSIX_C_SOURCE value for getaddrinfo()
|
||||
The correct _POSIX_C_SOURCE value is 200112L, not 201112L in features.h.
|
||||
|
||||
getcontext.3
|
||||
Carlos O'Donell
|
||||
Exemplar structure should use 'ucontext_t'.
|
||||
In glibc we just finished a round of purging 'struct ucontext'
|
||||
which is not in the POSIX reserved namespace of *_t tags. This has
|
||||
some consequences to applications using the non-standard struct
|
||||
ucontext:
|
||||
https://sourceware.org/glibc/wiki/Release/2.26#Removal_of_.27struct_ucontext.27
|
||||
but it also fixes a namespace conformance issue which is always a
|
||||
longterm pain for large portable programs.
|
||||
|
||||
It was noted by Peter Maydell
|
||||
(https://sourceware.org/bugzilla/show_bug.cgi?id=21457) that the
|
||||
linux man pages still had references to 'struct ucontext' but only
|
||||
in the form of an exemplar structure.
|
||||
|
||||
The patch fixes the exemplar to match what is in glibc
|
||||
and therefore it won't ever suggest users can use 'struct
|
||||
ucontext'.
|
||||
|
||||
getgrent.3
|
||||
Michael Kerrisk
|
||||
Note glibc 2.22 changes for feature test macro requirements
|
||||
|
||||

|
||||
ptsname.3
|
||||
unlockpt.3
|
||||
Ferdinand Thiessen [Michael Kerrisk]
|
||||
Update feature test macro-requirements for glibc 2.24
|
||||
|
||||
if_nametoindex.3
|
||||
Douglas Caetano dos Santos
|
||||
Add ENODEV error for if_nametoindex()
|
||||
Checked against glibc and kernel code: when given name isn't
|
||||
a valid interface, kernel returns ENODEV and glibc just
|
||||
forwards it.
|
||||
|
||||
malloc.3
|
||||
Michael Kerrisk
|
||||
Document the reallocarray() added in glibc 2.26
|
||||
|
||||
nl_langinfo.3
|
||||
Michael Kerrisk
|
||||
Note feature test macro requirements for nl_langinfo_l()
|
||||
|
||||
posix_madvise.3
|
||||
Dr. Tobias Quathamer
|
||||
Remove paragraph about POSIX_FADV_NOREUSE
|
||||
POSIX_FADV_NOREUSE is documented for posix_fadvise, and a
|
||||
corresponding POSIX_MADV_NOREUSE flag is not specified by POSIX.
|
||||
|
||||
Thanks to Marc Lehmann <debian-reportbug@plan9.de>
|
||||
See https://bugs.debian.org/865699
|
||||
|
||||
ptsname.3
|
||||
Michael Kerrisk [Arjun Shankar]
|
||||
Since glibc 2.26, ptsname_r() no longer gives EINVAL for buf==NULL
|
||||
|
||||
rand.3
|
||||
Michael Kerrisk
|

|
||||
The prefix 0x may be capitalized as 0X.
|
||||
|
||||
See ISO/IEC 9899:1999.
|
||||
|
||||
sysconf.3
|
||||
Michael Kerrisk [Pavel Tikhomirov]
|
||||
Rework RETURN VALUE description to add more detail
|
||||
Make the discussion clearer, and add a few details.
|
||||
Also, fix the problem report from Pavel Tikhomirov
|
||||
who noted that the man page falsely said that errno
|
||||
is not changed on a successful return.

signal.7
|
||||
Michael Kerrisk [lilydjwg]
|
||||
Since Linux 3.8, read(2) on an inotify FD is restartable with SA_RESTART
|
||||
See https://bugzilla.kernel.org/show_bug.cgi?id=195711
|
||||
Michael Kerrisk
|
||||
read() from an inotify FD is no longer interrupted by a stop signal
|
||||
(Change was in Linux 3.8.)
|
||||
|
||||
tcp.7
|
||||
Michael Kerrisk
|
||||
Document value '2' for tcp_timestamps
|
||||
Since Linux 4.10, the value '2' is meaningful for tcp_timestamps
|
||||
Ruben Kerkhof
|
||||
Change default value of tcp_frto
|
||||
The default changed in c96fd3d461fa495400df24be3b3b66f0e0b152f9
|
||||
(Linux 2.6.24).
|
||||
|
||||
ld.so.8
|
||||
Michael Kerrisk
|
||||
Greatly expand the explanation of LD_DYNAMIC_WEAK
|
||||
Carlos O'Donell
|
||||
Expand DT_RUNPATH details.
|
||||
ld.so.8: Expand DT_RUNPATH details.
|
||||
|
||||
Every 3 years we get asked why DT_RUNPATH doesn't work like DT_RPATH.
|
||||
The most recent question was here:
|
||||
https://www.sourceware.org/ml/libc-help/2017-06/msg00013.html
|
||||
|
||||
We need to expand the description of DT_RUNPATH to cover this
|
||||
situation and explain that the DT_RUNPATH entries apply only to the
|
||||
immediate DT_NEEDED, not that of another, say dlopen'd child object.
|
||||
Michael Kerrisk
|
||||
Since glibc 2.2.5, LD_PROFILE is ignored in secure-execution mode
|
||||
Michael Kerrisk
|
||||
Make notes on secure-execute mode more prominent
|
||||
Place each note on secure-execution mode in a separate
|
||||
paragraph, to make it more obvious.
|
||||
Michael Kerrisk
|
||||
Note that libraries in standard directories are not normally set-UID
|
||||
In secure mode, LD_PRELOAD loads only libraries from standard
|
||||
directories that are marked set-UID. Note that it is unusual for
|
||||
a library to be marked in this way.
|
||||
Michael Kerrisk
|
||||
SEE ALSO: add elf(5)
|
||||
Michael Kerrisk
|
||||
Note version where secure-execution started ignoring LD_USE_LOAD_BIAS
|
||||
Michael Kerrisk
|
||||
Correct glibc version that ignores LD_SHOW_AUXV in secure-execution mode
|
||||
Ignored since 2.3.4 (not 2.3.5).
|
||||
Michael Kerrisk
|
||||
Rewrite LD_DEBUG_OUTPUT description and note that .PID is appended
