* libc: fix cases of undefined behavior.Pedro F. Giffuni2018-08-071-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These were found by the Undefined Behavious GsoC project at NetBSD: Avoid undefined behavior in ftok(3) Do not change the signedness bit with a left shift operation. Cast to unsigned integer to prevent this. ftok.c:56:10, left shift of 123456789 by 24 places cannot be represented in type 'int' ftok.c:56:10, left shift of 4160 by 24 places cannot be represented in type 'int' Avoid undefined behavior in an inet_addr.c Do not change the signedness bit with a left shift operation. Cast to unsigned integer to prevent this. inet_addr.c:218:20, left shift of 131 by 24 places cannot be represented in type 'int' Detected with micro-UBSan in the user mode.

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-206-5/+17
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* libc: remove use of archaic __P() macroEd Maste2017-03-301-4/+3

* Renumber copyright clause 4Warner Losh2017-02-286-6/+6
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

| * Bring final version of libbind:Pedro F. Giffuni2014-08-0510-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From http://www.isc.org/downloads/libbind/ The libbind functions have been separated from the BIND suite as of BIND 9.6.0. Originally from older versions of BIND, they have been continually maintained and improved but not installed by default with BIND 9. This standard resolver library contains the same historical functions and headers included with many Unix operating systems. In fact, most implementations are based on the same original code. At present, NetBSD maintains libbind code, now known as "netresolv". Notes: svn path=/vendor/resolver/dist/; revision=269610

* | Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}Marcel Moolenaar2014-03-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.
