* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | 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

Bring in required TLI library routines to support this. Since we don't support TLI we've essentially copied what NetBSD has done, adding a thin layer to emulate direct the TLI calls into BSD socket calls. This is mostly from Sun's tirpc release that was made in 1994, however some fixes were backported from the 1999 release (supposedly only made available after this porting effort was underway). The submitter has agreed to continue on and bring us up to the 1999 release. Several key features are introduced with this update: Client calls are thread safe. (1999 code has server side thread safe) Updated, a more modern interface. Many userland updates were done to bring the code up to par with the recent RPC API. There is an update to the pthreads library, a function pthread_main_np() was added to emulate a function of Sun's threads library. While we're at it, bring in NetBSD's lockd, it's been far too long of a wait. New rpcbind(8) replaces portmap(8) (supporting communication over an authenticated Unix-domain socket, and by default only allowing set and unset requests over that channel). It's much more secure than the old portmapper. Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded to support TI-RPC and to support IPV6. Umount(8) is also fixed to unmount pathnames longer than 80 chars, which are currently truncated by the Kernel statfs structure.

* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579

* Correct a bug in the 'allow arbitrary number of socket descriptors' changesBill Paul1997-10-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | made to the RPC code some months ago. The value of __svc_fdsetsize is being calculated incorrectly. Logically, one would assume that __svc_fdsetsize is being used as a substitute for FD_SETSIZE, with the difference being that __svc_fdsetsize can be expanded on the fly to accomodate more descriptors if need be. There are two problems: first, __svc_fdsetsize is not initialized to 0. Second, __svc_fdsetsize is being calculated in svc.c:xprt_registere() as: __svc_fdsetsize = howmany(sock+1, NFDBITS); This is wrong. If we are adding a socket with index value 4 to the descriptor set, then __svc_fdsetsize will be 1 (since fds_bits is an unsigned long, it can support any descriptor from 0 to 31, so we only need one of them). In order for this to make sense with the rest of the code though, it should be: __svc_fdsetsize = howmany(sock+1, NFDBITS) * NFDBITS; Now if sock == 4, __svc_fdsetsize will be 32. This bug causes 2 errors to occur. First, in xprt_register(), it causes the __svc_fdset descriptor array to be freed and reallocated unnecessarily. The code checks if it needs to expand the array using the test: if (sock + 1 > __svc_fdsetsize). The very first time through, __svc_fdsetsize is 0, which is fine: an array has to be allocated the first time out. However __svc_fdsetsize is incorrectly set to 1, so on the second time through, the test (sock + 1 > __svc_fdsetsize) will still succeed, and the __svc_fdset array will be destroyed and reallocated for no reason. Second, the code in svc_run.c:svc_run() can become hopelessly confused. The svc_run() routine malloc()s its own fd_set array using the value of __svc_fdsetsize to decide how much memory to allocate. Once the xprt_register() function expands the __svc_fdset array the first time, the value for __svc_fdsetsize becomes 2, which is too small: the resulting calculation causes the code to allocate an array that's only 32 bits wide when it actually needs 64 bits. It also uses the valuse of __svc_fdsetsize when copying the contents of the __svc_fdset array into the new array. The end result is that all but the first 32 file descriptors get lost. Note: from what I can tell, this bug originated in OpenBSD and was brought over to us when the code was merged. The bug is still there in the OpenBSD source.

* - major overhaul to make this deal with unlimited fd's.Peter Wemm1996-12-301-56/+68
| | | | | | | | | | | | | | | - kill non-FD_SETSIZE code Obtained from: a diff of FreeBSD vs. OpenBSD/NetBSD rpc code. Note, there was a nasty bug with our old code here. It would trash the stack if a fd > 31 was passed in. It was using a "long" as though it was an "fd_set", ie: it was assuming that a long was 256 bits wide. :-( This has been lurking here for a while, since the FD_SETSIZE #ifdef's were first implemented.
