* Make the size for the syn cache hash array tunable. As we arebluhm2016-07-201-2/+7
| | | | | | | | swapping between two syn caches for random reseeding anyway, this feature can be added easily. When the cache is empty, there is an opportunity to change the hash size. This allows an admin under SYN flood attack to defend his machine. Suggested by claudio@; OK jung@ claudio@ jmc@

* fts_open() requires that the list passed as argument to contain at leastmillert2016-06-282-4/+12
| | | | | | one path. When the list is empty (contain only a NULL pointer), return EINVAL instead of pretending to succeed, which will cause a NULL pointer deference in a later fts_read() call. From FreeBSD.

* Do not return an error in fts_open(3) if one of the paths in argvmillert2016-06-281-9/+2
| | | | | | is empty. Otherwise, programs using fts(3) will report an error if one of the paths is empty instead of just treating it as a non-existent file. OK guenther@

* remove hppa64 port, which we never got going beyond broken single users.deraadt2016-05-111-4/+3

* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-072-9/+61
| | | | | | | | | | | | | | | | | This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@
* Eliminate userspace caching by getlogin_r/setlogin; make the getloginguenther2016-03-301-53/+8
| | | | | | | | syscall behave exactly like userspace getlogin_r() and rename it to match. Eliminate the reduced-to-no-op wrappers of the syscalls. Eliminate the unnecessary per-thread static buffering by getlogin(). ok kettenis@ deraadt@

* for some time now mandoc has not required MLINKS to functionjmc2016-03-301-104/+1
| | | | | | | | | | | | correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

* Rearrange C runtime bits: now that ld.so exports environ and __progname,guenther2016-03-202-8/+8
| | | | | | | | | | | move their definitions and initialization in static links to libc.a Make crt0 always invoke a new func _csu_finish() in libc to process the auxv and to either register the ld.so cleanup function (in dynamic links) or initialize environ and __progname and do MC_DISABLE_KBIND (in static links). In libc, get pagesize from auxv; cache that between getpagesize() and sysconf(_SC_PAGESIZE) ok mpi@ "good time" deraadt@
