Based on a patch by Bjarni Ingi Gislason.

According to SI, ""The numerical value always precedes the unit,
and a space is always used to separate the unit from the number
[...] The only exceptions to this rule are for the unit symbols
for degree, minute, and second for plane angle."

Mike Rapoport fa744079f6 ioctl_userfaultfd.2: Update uffdio_api.features description 
There is no requirement that uffdio_api.features must be zero
for newer kernels. This field actually defines what features
space would like to enable.

 2017-08-15 21:28:54 +02:00
Aleksa Sarai 0ec74af9db ioctl_tty.2: Add TIOCGPTPEER documentation 
This is an ioctl(2) recently added by myself, to allow for
container runtimes and other programs that interact with
(potentially hostile) Linux namespaces to safely create
{master,slave} pseudoterminal pairs without needing to open
potentially unsafe /dev/pts/... filenames that may be malicious
mount points or similar in an untrusted namespace (avoiding the
endless issues with ptsname(3) and similar approaches).

Kees Cook 5defc77db0 seccomp.2: Clarify SECCOMP_RET_KILL kills tasks not processes 
Zach Reizner pointed out a mismatch between kernel behavior and the
man-page documentation of SECCOMP_RET_KILL which kills tasks not
processes.

Carlos O'Donell 7693d1e5c0 getpid.2: 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
~~~
3.2.3. Calls to getpid are no longer cached

The PID cache used by glibc has been removed. In certain scenarios
the cache was not 100% reliable and because of that it was deemed
safer to remove the cache than to potentially return a wrong
answer.

Applications performing getpid() calls in a loop will see the
worst case performance degradation as the library call will
perform a system call at each invocation. Such application uses
were known to exist at least in OpenSSL (fork()-based PRNG
invalidation), but supporting the performance of that specific
invalidation mechanism was not judged to have sufficient value
against immediate and long-term benefits of removing the cache.

Functional reasons exist for the PID cache removal including
problems with PID namespaces, interoperability with raw system
calls (BZ#17214, Chrome: Issue 800183004), and improvements to
spawn (BZ#19957). Performance is actually increased in
pthread_create() with the removal of the cache since the
implementation no longer needs to perform an invalidation step.

Applications performing getpid() in a loop that need to do some
level of fork()-based invalidation can instead use
pthread_atfork() to register handlers to handle the invalidation.
There is work-in-progress to make pthread_atfork() available to
applications that do not link against libpthread.so (Provide
pthread_atfork() without libpthread.so).

Other kinds of invalidation are not supported and the glibc
community will actively look at a kernel assisted mechanism for
state management across fork(), vfork(), clone() and other
interfaces which can benefit from such semantics. It is the same
type of solution required for crypto PRNG reset across such API
calls.

Then add details regarding coredump behavior.  Before Linux 4.11,
there was no way to get coredumps from such crashes.  Now we can
at least get crashes from single threaded processes.

Michael Kerrisk a18cc179a7 ioctl_userfaultfd.2: Drop some unneeded text 
From a conversation with Mike Rapoport:

What does "consistent" mean?
    Actually, I though I've copied this text from Andrea's docs,
    but now I've found out it was my wording and I really don't
    remember now what was my intention for "consistent" :) My
    guess is that I was thinking about atomicity of UFFDIO_COPY,
    or the fact that from the faulting thread perspective the
    page fault handling is the same whether it's done in kernel
    or via userfaultfd...  That said, maybe it'd be better just
    to drop "in a consistent way".

Michael Kerrisk 637512edfa ioctl_userfaultfd.2: Rework list of ioctl() operations as subsections 
Mainly, this means that we drop one level of indentation, which is
useful, since the error lists also add a level of indentation,
and the text overall becomes a little overindented.

Michael Kerrisk 74bd6e931a ioctl_userfaultfd.2: Rework formatting of structures for each ioctl() operation 
Trying to place structure names on the same line as the ioctl()
operation names makes the lines two busy. And, conventionally,
the space after a hanging-list constant name is optionally used
to indicate the kernel version number where the constant was
introduced..
