* Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}marcel2014-03-041-1/+1
| | | | | | | | | | | 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.

* The getcontext() from the __fillcontextx() call in thekib2013-05-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | check_deferred_signal() returns twice, since handle_signal() emulates the return from the normal signal handler by sigreturn(2)ing the passed context. Second return is performed on the destroyed stack frame, because __fillcontextx() has already returned. This causes undefined and bad behaviour, usually the victim thread gets SIGSEGV. Avoid nested frame and the need to return from it by doing direct call to getcontext() in the check_deferred_signal() and using a new private libc helper __fillcontextx2() to complement the context with the extended CPU state if the deferred signal is still present. The __fillcontextx() is now unused, but is kept to allow older libthr.so to be used with the new libc. Mark __fillcontextx() as returning twice [1].

* Change index() and rindex() to a weak alias.ed2012-01-052-2/+2
| | | | | | | | This allows people to still write statically linked applications that call strchr() or strrchr() and have a local variable or function called index. Discussed with: bde@
* Merge index() and strchr() together.ed2012-01-033-7/+11
| | | | | | | | | | | | | | | | | As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead. Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications. Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr(). This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.

* Mark uname(), getdomainname() and setdomainname() with COMPAT_FREEBSD4.ed2008-11-091-3/+2
| | | | | | | | | | | | | | | | | | | | | Looking at our source code history, it seems the uname(), getdomainname() and setdomainname() system calls got deprecated somewhere after FreeBSD 1.1, but they have never been phased out properly. Because we don't have a COMPAT_FREEBSD1, just use COMPAT_FREEBSD4. Also fix the Linuxolator to build without the setdomainname() routine by just making it call userland_sysctl on kern.domainname. Also replace the setdomainname()'s implementation to use this approach, because we're duplicating code with sysctl_domainname(). I wasn't able to keep these three routines working in our COMPAT_FREEBSD32, because that would require yet another keyword for syscalls.master (COMPAT4+NOPROTO). Because this routine is probably unused already, this won't be a problem in practice. If it turns out to be a problem, we'll just restore this functionality. Reviewed by: rdivacky, kib
