ioctl_userfaultfd.2
|
|
|
|
Michael Kerrisk, Mike Rapoport
|
|
|
|
New page describing ioctl(2) operations for userfaultfd
|
|
|
|
|
|
|
|
statx.2
|
|
|
|
David Howells, Michael Kerrisk [Andreas Dilger]
|
|
|
|
New page describing statx(2) system call added in Linux 4.11
|
|
|
|
|
|
|
|
userfaultfd.2
|
|
|
|
Mike Rapoport, Michael Kerrisk [Andrea Arcangeli]
|
|
|
|
New page describing userfaultfd(2) system call.
|
|
|
|
|
|
|
|
pthread_atfork.3
|
|
|
|
Michael Kerrisk
|
|
|
|
New page describing pthread_atfork(3)
|
|
|
|
|
|
|
|
slabinfo.5
|
|
|
|
Michael Kerrisk
|
|
|
|
Rewrite to try to bring the content close to current reality
|
|
|
|
There's still gaps to fill in, but the existing page
|
|
|
|
was in any case hugely out of date.
|
|
|
|
|
|
|
|
inode.7
|
|
|
|
Michael Kerrisk
|
|
|
|
New page with information about inodes
|
|
|
|
David Howells provided a statx(2) page that duplicated much of
|
|
|
|
the information from form stat(2). Avoid such duplication
|
|
|
|
by moving the common information in stat(2) and statx(2)
|
|
|
|
to a new page.
|
|
|
|
|
|
|
|
|
|

Renamed pages
|
|
|

--------------
|
|
|
|
|
|
|
|
ioctl_console.2
|
|
|
|
Michael Kerrisk
|
|
|
|
Renamed from console_ioctl.4
|
|
|
|
Most ioctl() man pages are in section 2, so move this one there
|
|
|
|
for consistency.
|
|
|
|
Michael Kerrisk
|
|
|
|
Note type of 'argp' for a various operations
|
|
|
|
For some commands, there was no clear statement about the type
|
|
|
|
of the 'argp' argument.
|
|
|
|
|
|
|
|
ioctl_tty.2
|
|
|
|
Michael Kerrisk
|
|
|
|
Renamed from tty_ioctl(4)
|
|
|
|
All other ioctl(2) pages are in section 2. Make this
|
|
|
|
page consistent.

Add/replace references to inode(7)
|
|
|
|
|
|
|
|
clone.2
|
|
|
|
Michael Kerrisk
|
|
|
|
CLONE_NEWCGROUP by an unprivileged process also causes an EPERM error
|
|
|
|
|
|
|
|
clone.2
|
|
|
|
unshare.2
|
|
|
|
Michael Kerrisk
|
|
|
|
Exceeding one of the limits in /proc/sys/user/* can cause ENOSPC
|
|
|
|
Michael Kerrisk
|
|
|
|
CLONE_NEWPID yields ENOSPC if nesting limit of PID namespaces is reached
|
|
|
|
Michael Kerrisk
|
|
|
|
Exceeding the maximum nested user namespace limit now gives ENOSPC
|
|
|
|
Formerly, if the limit of 32 nested user namespaces was exceeded,
|
|
|
|
the error EUSERS resulted. Starting with Linux 4.9, the error
|
|
|
|
is ENOSPC.
|
|
|
|
|
|
|
|
epoll_ctl.2
|
|
|
|
Michael Kerrisk
|
|
|
|
Defer to poll(2) for an explanation of EPOLLIN
|
|
|
|
Michael Kerrisk [Nicolas Biscos]
|
|
|
|
EPOLLERR is also set on write end of a pipe when the read end is closed
|
|
|
|
Michael Kerrisk [Nicolas Biscos]
|
|
|
|
Give the reader a clue that the 'events' field can be zero
|
|
|
|
'events' specified as zero still allows EPOLLHUP and
|
|
|
|
EPOLLERR to be reported.
|
|
|
|
|
|
|
|
_exit.2
|
|
|
|
Michael Kerrisk
|
|
|
|
On exit, child processes may be inherited by a "subreaper"
|
|
|
|
It is no longer necessarily true that orphaned processes
|
|
|
|
are inherited by PID 1.
|
|
|
|
Michael Kerrisk
|
|
|
|
Only the least significant byte of exit status is passed to the parent
|
|
|
|
|
|
|
|
fcntl.2
|
|
|
|
Michael Kerrisk
|
|
|
|
Mention memfd_create() in the discussion of file seals
|
|
|
|
Give the reader a clue about what kinds of objects can
|
|
|
|
be employed with file seals.
|
|
|
|
Michael Kerrisk
|
|
|
|
File seals are not generally applicable to tmpfs(5) files
|
|
|
|
As far as I can see, file seals can be applied only to
|
|
|
|
memfd_create(2) file descriptors. This was checked by experiment
|
|
|
|
and by reading mm/shmem.c::shmem_get_inode((), where one finds
|
|
|
|
the following line that applies to all new shmem files:
|
|
|
|
|
|
|
|
info->seals = F_SEAL_SEAL;
|
|
|
|
|
|
|
|
Only in the code of the memfd_create() system call is this
|
|
|
|
setting reversed (in mm/shmem.c::memfd_create):
|
|
|
|
|
|
|
|
if (flags & MFD_ALLOW_SEALING)
|
|
|
|
info->seals &= ~F_SEAL_SEAL;
|
|
|
|
|
|
|
|
fork.2

|
Alexander Miller
|
|
|
|
Move .so directive to first line
|
|
|
|
Improves compatibility with the man and other dumb tools
|
|
|
|
that process man page files.
|
|
|
|
|
|
|
|
getpid.2
|

|
mmap.2
|
|
|
|
Michael Kerrisk
|
|
|
|
Remove ancient reference to flags that appear on some other systems
|
|
|
|
MAP_AUTOGROW, MAP_AUTORESRV, MAP_COPY, and MAP_LOCAL may have
|
|
|
|
appeared on some systems many years ago, but the discussion here
|
|
|
|
mentions no details and the systems and flags probably ceased to
|
|
|
|
be relevant long ago. So, remove this text.
|
|
|
|
Michael Kerrisk
|
|
|
|
SEE ALSO: add userfaultfd(2)

Mike Frysinger
|

|
|
PR_SET_MM: Refine CONFIG_CHECKPOINT_RESTORE requirement
|
|
|
|
The Linux 3.10 release dropped the c/r requirement and opened it
|
|
|
|
up to all users.
|
|
|
|
Mike Frysinger
|
|
|
|
PR_SET_MM: Document new PR_SET_MM_MAP{,_SIZE} helpers

Mike Frysinger
|
|
|
|
PR_SET_MM: Document arg4/arg5 zero behavior

|
The kernel will immediately reject calls where arg4/arg5 are not
|
|
|
|
zero. See kernel/sys.c:prctl_set_mm().
|
|
|
|
Michael Kerrisk

select.2
|
|
|
|
Michael Kerrisk [Matthew Wilcox, Carlos O'Donell]
|
|
|
|
Linux select() is buggy wrt POSIX in its check for EBADF errors
|
|
|
|
Michael Kerrisk
|
|
|
|
Show correspondence between select() and poll() readiness notifications
|
|

sigaction.2

Michael Kerrisk
|
|
|
|
Show the prototype of an SA_SIGINFO signal handler
|
|
|
|
|
|
|
|
signalfd.2
|
|
|
|
Michael Kerrisk
|
|
|
|
SIGKILL and SIGSTOP are silently ignored in 'mask'
|
|
|
|
|
|
|
|
sigprocmask.2
|
|
|
|
Dmitry V. Levin
|
|
|
|
Do not specify an exact value of rt_sigprocmask's 4th argument
|
|
|
|
As sizeof(kernel_sigset_t) is not the same for all architectures,
|
|
|
|
it would be better not to mention any numbers as its value.
|
|
|
|
Michael Kerrisk
|
|
|
|
'set' and 'oldset' can both be NULL
|
|
|
|
|
|
|
|
sigwaitinfo.2

Restructure field descriptions as a hanging list

|
|
|
|
Remove "Other systems" subsection
|
|
|
|
These details about other systems were added in 1999,
|
|
|
|
and were probably of limited use then, and even less today.
|
|
|
|
However, they do clutter the page, so remove them.

Tweak description of AT_EMPTY_PATH
|

|
Currently it says when dirfd is AT_FDCWD it can be something
|
|
|
|
other than directory, which doesn't make much sense. Just swap
|
|
|
|
the order of sentences.

user_namespaces.7: Fixes to example
|
|
|
|
Stephan Bergmann
|
|
|
|
While toying around with the userns_child_exec example program on the
|
|
|
|
user_namespaces(7) man page, I noticed two things:
|
|
|
|
|
|
|
|
* In the EXAMPLE section, we need to mount the new /proc before
|
|
|
|
looking at /proc/$$/status, otherwise the latter will print
|
|
|
|
information about the outer namespace's PID 1 (i.e., the real
|
|
|
|
init). So the two paragraphs need to be swapped.
|
|
|
|
|
|
|
|
* In the program source, make sure to close pipe_fd[0] in the
|
|
|
|
child before exec'ing.
