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 Modified: head/include/rpc/auth.h head/include/rpc/auth_unix.h head/lib/libc/rpc/auth_unix.c head/lib/libc/rpc/authunix_prot.c head/lib/libc/rpc/clnt_perror.c head/lib/libc/rpc/clnt_vc.c head/lib/libc/rpc/rpc_generic.c head/lib/libc/rpc/rpc_soc.3 head/lib/libc/rpc/rpcb_clnt.c head/lib/libc/rpc/svc_auth_unix.c head/lib/libc/rpc/svc_run.c head/sys/rpc/auth.h head/sys/rpc/clnt_vc.c head/sys/rpc/rpcb_clnt.c Modified: head/include/rpc/auth.h ============================================================================== --- head/include/rpc/auth.h Fri Aug 31 23:28:41 2012 (r239962) +++ head/include/rpc/auth.h Sat Sep 1 02:56:17 2012 (r239963) @@ -243,14 +243,13 @@ __END_DECLS * System style authentication * AUTH *authunix_create(machname, uid, gid, len, aup_gids) * char *machname;
