New and rewritten pages
|
||||
-----------------------
|
||||
|
||||
A note from Christoph Hellwig prompted me to perform a task that has
|
||||
been queued for a while: merging the text of the man pages for the
|
||||
*at([23]) ("directory file descriptor") APIs into their corresponding
|
||||
traditional pages. When the *at([23]) pages were originally written
|
||||
(mostly in 2006), the APIs were not part of POSIX and (in most cases)
|
||||
were not available on other systems. So, it made some sense to wall
|
||||
them off into their own separate pages. Eight years later, with the
|
||||
APIs now all in POSIX (except scandirat()), it is much more sensible
|
||||
to document the newer APIs alongside their traditional counterparts,
|
||||
so that the newer APIs are not "hidden", and the reader can more
|
||||
easily see the differences between the APIs.
|
||||
|
||||
Thus, the text of 14 pairs of pages has been merged, and the "merged
|
||||
from" pages have been converted to links to the "merged to" pages.
|
||||
Along the way, a few other fixes were made to the pages, as noted
|
||||
below.
|
||||
|
||||
One page that did not undergo such a change was utimensat(2), which
|
||||
is different enough from utime(2) that it warrants a separate page.
|
||||
Unlike the other *at() pages, the utimensat(2) page was also already
|
||||
self-contained, rather than defining itself in terms of differences
|
||||
from utime(2) as the other *at() pages did.
|
||||
|
||||
access.2
|
||||
Michael Kerrisk
|
||||
Merge text from faccessat(2)
|
||||
Michael Kerrisk
|
||||

||||

Make it clearer that glibc and syscall APIs differ for PTRACE_PEEK*
|

Thanks to Denys Vlasenko's additions in 78686915aed6bd12
|
||||
this page does note that the glibc API for PTRACE_PEEK*
|
||||
differs from the raw syscall interface. But, as the report
|
||||
at https://bugzilla.kernel.org/show_bug.cgi?id=70801 shows,
|
||||
this information could be more obvious. This patch makes its so.

resolv.conf.5
|
||||
Carlos O'Donell
|
||||
DESCRIPTION: mention that the data is trusted
|
||||
In a recent discussion about DNSSEC it was brought to my
|
||||
attention that not all system administrators may understand
|
||||
that the information in /etc/resolv.conf is fully trusted.
|
||||
The resolver implementation in glibc treats /etc/resolv.conf
|
||||
as a fully trusted source of DNS information and passes on
|
||||
the AD-bit for DNSSEC as trusted.
|
||||
|
||||
This patch adds a clarifying sentence to make it absolutely
|
||||
clear that indeed this source of information is trusted.
