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.

seccomp(2): Expand SECCOMP_RET_KILL documentation
...
First clarify that the process cannot catch this SIGSYS signal.
While the text currently says that, it's easy (IMO) to read
ambiguously and that it's referring to default behavior (no
handler -> process exits).
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.

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".

ioctl_list.2: BLKRASET/BLKRAGET take unsigned long
...
The BLKRASET/BLKRAGET ioctls() take unsigned long, if I pass int * to
the BLKRAGET ioctl on x86_64 (or on any other arch where sizeof(int) !=
sizeof(long)) the BLKRAGET ioctl will rewrite four bytes on the stack.
If you look at block/ioctl.c in kernel sources you can clearly see that
BLKRAGET ioctl calls put_long().
Compile following reproducer and run it as ./a.out /dev/sda, you can see
that the second member of the array will be zeroed. If you change the
array to have only one member you will see stack smashing trace.
I also wonder if it's OK to pass int value to ioctl() at all, the arg
value seems to be unsigned long in the syscall definition in fs/ioctl.c
and there does not seem to be any glibc magic around the syscall.

fd = open(argv[1], O_RDONLY);
if (fd < 0) {

return 1;
}
ioctl(fd, BLKRAGET, ra);
fprintf(stderr, "%i %i\n", ra[0], ra[1]);
return 0;
}

fcntl.2: 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;
