kamil a36fdb1010 Try to fix the evbppc-powerpc64 build
Avoid "comparison between signed and unsigned integer expressions" on
Big-Endian hosts.

kamil 7adf6ec6dd Register a new directory in common/lib/libc/misc
Registe misc/ with ubsan.c.

kamil aee9a63f2a Tidy up the comment in ubsan.c
As noted, style has no impact on the comparison of a similar code.
This version is a reimplementation from scratch with no code and no
algirithm (whenever possible) reuse.

Public symbols and struct layout must be kept in sync with the code
generation part. It casues violation of the style like with long filenames.

My previous comment was 'too perfect' and could trigger some unnecessary
attention.

kamil 9aff107674 Import micro-UBSan (ubsan.c)
This is a reimplementation of the Undefined Behavior Sanitizer with the
following properties:
 - pure and clean-room C implementation,
 - no -fsanitize=vpts support, as it requires RTTI support and C++
   low-level routies to validate whether C++ objects are compatible
 - designed to be used inside libc and known as uUBSan or user-UBSan
 - designed to be shared with kernel and known as kUBSan or kernel-UBSan
 - designed to be usable with ATF tests as a standalone runtime,
   reachable without any MK* switches
 - designed to be safer for hardening as it does not have side effects on
   executables like writing to a selected location on demand
 - controllable with environment variable LIBC_UBSAN with options:
   * a - abort on report
   * A - do not abort on a report (unless a failure is unrecoverable)
   * e - output report to stderr
   * E - do not output report on stderr
   * l - output report on syslog (LOG_DEBUG | LOG_USER)
   * L - do not output report on syslog
   * o - output report on stdout
   * O - do not output report on stdout
   The default options are: "AeLO".
 - compatible with Clang (3.8, 7.x) and GCC (6.x) code generation
 - all handlers (except =vptr) from Clang/LLVM up to 7svn are supported

Tested with Clang amd64+i386 and GCC amd64+i386.

mrg 51502cf62d updates for GCC 6.4:
- remove many _DIAGASSERT() checks against not NULL for functions
  with arguments with nonnull attributes.  (probably more to come,
  the set between x86 and sparc us disjoint.)

- port libsanitizer's GetPcSpBp() to sparc, sparc64 and amd64.
2018-02-04 20:22:17 +00:00
mrg 8fdd01b3ee fixes for GCC 6:
- -Wstrict-prototypes is not available for C++, so don't try to
  ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
  with arguments with nonnull attributes.  in two cases, leave
  code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
  to assume the caller will have a frame.fair

kamil c5b83981a9 Add bunch of missing includes of namespace.h in libc
The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

This change eliminates usage of the global changes of the following symbols:
 - strlcat -> _strlcat
 - sysconf -> __sysconf
 - closedir -> _closedir
 - fparseln -> _fparseln
 - kill -> _kill
 - mkstemp -> _mkstemp
 - reallocarr -> _reallocarr
 - strcasecmp -> _strcasecmp
 - strncasecmp -> _strncasecmp
 - strptime -> _strptime
 - strtok_r -> _strtok_r
 - sysctl -> _sysctl
 - dlopen -> __dlopen
 - dlclose -> __dlclose
 - dlsym -> __dlsym

abhinav 3ed54b8d62 Use .Fn to refer a function name instead of Nm.
Also, use Xr to refer problib(3) in the HISTORY section instead of Nm.

While parsing the man pages, any .Nm occurrence gets replaced by the
value specified in the NAME section. Referencing individual function
names with .Nm was causing makemandb(8) to replicate the complete
NAME section for every such occurrence. This was leading to an
ugly looking snippet in apropos(1)'s output when searched for
any of these man pages.

from uvm_mmap() to the new vnode-specific vn_mmap().  add new uvm_mmap_dev()

use the new fileop in drm2 so that libdrm can use mmap() to map things
like on other platforms (instead of the ioctl that we have used so far).

khorben 00b617c08a Look for the character to locate before checking for the NUL character
As documented in PR port-i386/49208, this fixes strchr(s, '\0'), as used by
the FAT first-stage bootloader on x86 (bootxx_msdos).
strchr(s, '\0') is otherwise equivalent to strlen(string), which would
probably look nicer in the original file, dosfs.c from libsa.

Confirmed working in qemu and on real hardware.
