* 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

* Fix __rpc_getconfipPedro F. Giffuni2012-10-021-2/+4
| | | | | | | | | | | | | | | | | __rpc_getconfip is supposed to return the first netconf entry supporting tcp or udp, respectively. The code will currently return the *last* entry, plus it will leak memory when there is more than one such entry. This change matches the reference (OpenSolaris) implementation.

* Complete revert of r239963:Pedro F. Giffuni2012-09-271-7/+2
| | | | | | | | | | | | | | | | | | The attempt to merge changes from the linux libtirpc caused rpc.lockd to exit after startup under unclear conditions. After many hours of selective experiments and inconsistent results the conclusion is that it's better to just revert everything and restart in a future time with a much smaller subset of the changes. ____ MFC after: 3 days Reported by: David Wolfskill Tested by: David Wolfskill Notes: svn path=/head/; revision=241007
* Bring some changes from Bull's NFSv4 libtirpc implementation.Pedro F. Giffuni2012-09-011-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We especifically ignored the glibc compatibility changes but this should help interaction with Solaris and Linux. ____ Fixed infinite loop in svc_run() author Steve Dickson Tue, 10 Jun 2008 12:35:52 -0500 (13:35 -0400) Fixed infinite loop in svc_run() ____ __rpc_taddr2uaddr_af() assumes the netbuf to always have a non-zero data. This is a bad assumption and can lead to a seg-fault. This patch adds a check for zero length and returns NULL when found. author Steve Dickson Mon, 27 Oct 2008 11:46:54 -0500 (12:46 -0400) ____ Changed clnt_spcreateerror() to return clearer and more concise error messages. author Steve Dickson Thu, 20 Nov 2008 08:55:31 -0500 (08:55 -0500) ____ Converted all uid and gid variables of the type uid_t and gid_t. author Steve Dickson Wed, 28 Jan 2009 12:44:46 -0500 (12:44 -0500) ____ libtirpc: set r_netid and r_owner in __rpcb_findaddr_timed These fields in the rpcbind GETADDR call are being passed uninitialized to CLNT_CALL. In the case of x86_64 at least, this usually leads to a segfault. On x86, it sometimes causes segfaults and other times causes garbage to be sent on the wire. rpcbind generally ignores the r_owner field for calls that come in over the wire, so it really doesn't matter what we send in that slot. We just need to send something. The reference implementation from Sun seems to send a blank string. Have ours follow suit. author Jeff Layton Fri, 13 Mar 2009 11:44:16 -0500 (12:44 -0400) ____ libtirpc: be sure to free cl_netid and cl_tp When creating a client with clnt_tli_create, it uses strdup to copy strings for these fields if nconf is passed in. clnt_dg_destroy frees these strings already. Make sure clnt_vc_destroy frees them in the same way. author Jeff Layton Fri, 13 Mar 2009 11:47:36 -0500 (12:47 -0400) Obtained from: Bull GNU/Linux NFSv4 Project MFC after: 3 weeks Notes: svn path=/head/; revision=239963

* Extract the path from an AF_LOCAL sockaddr_un in a way that correctlyIan Dowse2001-05-121-2/+5
| | | | | | | | | | | | | | terminates the string in all cases, based on code from netstat(1). The path in a sockaddr_un is terminated either by a '\0', or by the end of the sockaddr as defined by sun_len. Previously, the code could write the "safety" '\0' beyond the end of the sockaddr (sockaddr_un's need only be large enough to store sun_len bytes), and writing into the the supplied sockaddr is bad anyway.

In the case of an AF_LOCAL address, it was missing the code to actually point the netbuf at the newly allocated sockaddr_un, so the caller ended up with a netbuf containing junk.

| | | | | | | | | | | | | | | | | | than the default buffer size in the old RPC code (8800 bytes), and it could not be overriden by the application. This caused problems with CFS (/usr/port/security/cfs). Change this default back to UDPMSGSIZE (8800 bytes), but more importantly, allow applications to use larger message sizes for all protocols if desired. Choose an arbitrary maximum message size of 256k instead of using the default as the maximum (which is silly).

* Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) andAlfred Perlstein2001-03-191-0/+816
associated changes that had to happen to make this possible as well as bugs fixed along the way. 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.
