* Add PF_LOCAL support in getaddrinfo(3) and getnameinfo(3):hrs2015-09-204-78/+205
| | | | | | | | | | | | | - In a PF_LOCAL address, "hostname" must begins with '/' and "servname" is always NULL. All of ai_flags are ignored. - PF_UNSPEC matches PF_LOCAL. EAI_SERVICE is not returned to make AF-independent programming easier; "servname" is always ignored in PF_LOCAL. In practice, PF_INET* and PF_LOCAL are mutually-exclusive because a hostname which begins with '/' is invalid in PF_INET*. No domain name resolution is performed for a PF_LOCAL address.

* Zero out a local variable also when PURIFY is not defined.tuexen2015-09-101-2/+0
| | | | | | | | | | | | This silence a warning brought up by valgrind whenever if_nametoindex is used. This was already discussed in PR 166483, but the code committed in r234329 guards the initilization with #ifdef PURIFY. Therefore, valgrind still complains. Since this code is not performance critical, always zero out the local variable to silence valgrind. PR: 166483 Discussed with: eadler@ MFC after: 4 weeks

* Switch libc from using _sig{procmask,action,suspend} symbols, whichkib2015-08-291-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | are aliases for the syscall stubs and are plt-interposed, to the libc-private aliases of internally interposed sigprocmask() etc. Since e.g. _sigaction is not interposed by libthr, calling signal() removes thr_sighandler() from the handler slot etc. The result was breaking signal semantic and rtld locking. The added __libc_sigprocmask and other symbols are hidden, they are not exported and cannot be called through PLT. The setjmp/longjmp functions for x86 were changed to use direct calls, and since PIC_PROLOGUE only needed for functional PLT indirection on i386, it is removed as well. The PowerPC bug of calling the syscall directly in the setjmp/longjmp implementation is kept as is.

* Hint out check for unsigned negative values.pfg2015-02-271-1/+1
| | | | | | | | | | | | | | | On FreeBSD socklen_t is unsigned so the check negative len in inet6_opt_append() is redundant and likely to be optimized away by the compiler. On other operating systems this is not necessarily so, and in the future we may want to sign it so leave the check in but place it in a secondary position as a subtle indication that the bogus check is intentional.

| | | | | | | | | | | | | | getgroupmembership() from invoking the correct backend in the compat case. Replace it with a nesting depth counter so it only blocks one level (the first is the group -> group_compat translation, the second is the actual backend). This is one of two bugs that break getgrouplist() in the compat case, the second being that the backend's own getgroupmembership() method is ignored. Unfortunately, that is not easily fixable without a redesign of our nss implementation (which is also needed to implement the +@group syntax in /etc/passwd). PR: 190055 MFC after: 1 week

As a side effect, this fixes a race condition which can occur if multiple threads call nsdispatch(3) concurrently before nsswitch.conf has been parsed. Previously, the thread holding conf_lock could cause other threads to return from nss_configure() before nsswitch.conf had been parsed, forcing them to fall back to the default sources for their NSS methods.

Also postpone the update of the nslexer.c file until we are sure we have generated it properly. These changes fix some very obscure build failures I encountered while building FreeBSD within a chroot that did not have devfs mounted. The specific errors looked like: .../libc.so.7: undefined reference to `_nsyyerror' .../libc.so.7: undefined reference to `_nsyyin' .../libc.so.7: undefined reference to `_nsyylex' .../libc.so.7: undefined reference to `_nsyylineno' .../libc.so.7: undefined reference to `_nsyytext' and were caused due to a mangled nslexer.c being linked into libc.
