* rpcb_clnt.c add mechanism to try v2 protocol firstlibtirpc-1-3-3-rc3Roberto Bergantinos Corpas2022-07-161-0/+2
| | | | | | | | | | | | | | | | | | | | There have been previous attempts to revert protocol tryout algorithm from v4,v3,v2 to previous v2,v4,v3 : https://www.spinics.net/lists/linux-nfs/msg89228.html Apart from GETADDR/NAT issue originating that proposed change, its possible that some legacy custom applications still use v2 of protocol with libtirpc. The change proposed here, introduces an environment variable "RPCB_V2FIRST" so that, if defined, old behaviour is used. This is more flexible and allow us to selectively pick what application reverts to old behaviour instead of a system-wide change.

* Remove AUTH_DES interfaces from auth_des.h.libtirpc-1-2-7-rc5Steve Dickson2020-12-011-15/+0
| | | | | | | | | | | | | | | The unsupported AUTH_DES authentication has be compiled out since commit d918e41d889 (Wed Oct 9 2019) replaced by API routines that return errors. To maintain a stable API and to cause future apps to fail to build, this patch removes the functions declaration from the header file. This also has the side effect of not changing the SONAME which always causes pain. Signed-off-by: Steve Dickson <steved@redhat.com>
* libtirpc: replace array with list for per-fd lockslibtirpc-1-2-7-rc3Jaime Caamano Ruiz2020-06-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Currently per-fd locks for the clients are pre-allocated up to the soft limit of maximum allowed open file desciptors per process as defined in __rpc_dtbsize(): if (getrlimit(RLIMIT_NOFILE, &rl) == 0) { return (tbsize = (int)rl.rlim_cur); } This limit can be arbitrarily large for any given process resulting in unreasonable memory allocation. For example, for systemd PID1 process this limit is set to 1073741816 since version 240. systemd is an indirect user of this library as it fetches information about users, groups, etc... This patch proposes a list implementation of per-fd locks based on glibc doubly linked lists. It also includes support for a fixed array based pre-allocation up to a compile-time defined limit of locks for equivalence to the previous implementation.

* Drop the xp_auth member of SVCXPRTPeter Rosin2015-10-301-1/+0

* Fix SVCAUTH lifetime issues and move towards SolarisPeter Rosin2015-10-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | There are lifetime problems with the current handling of SVCAUTH and the core library has no business ever destroying an SVCAUTH. These lifetime problems leads to the gss authenticator leaking a SVCAUTH when interleaved calls on the transport arrive with non-gss credential flavors. So, plagiarize the Solaris solution and keep an inlined SVCAUTH struct to make it obvious that the core library is not managing the life of SVCAUTH. Then point the old xp_auth pointer to the inlined SVCAUTH by default. This makes it possible to match the Solaris macro SVC_XP_AUTH, while still remaining compatible with any old external xp_auth pointer users. Adjust the gss authenticator to keep track of its own gss data per SVCXPRT. This is still not a good gss implementation, but it is at least better than before.

* Handle gss auth reference counting internallyBrendan Heading2015-10-301-28/+4
| | | | | | | | | | | | | | | | | The previous implementation of auth_get and auth_put used atomic builtins to allow thread-safe updating of a reference count for the AUTH object. This causes libtirpc not to build on a number of non-mainstream architectures which don't support the atomic builtins. In addition it exposed the feature as macros through a header file, rather than through the ABI, preventing the underlying implementation from being updated. This patch removes the API calls and handles the reference counting/ deallocation of the AUTH object internally.

* Use poll() instead of select() in svc_run()Thorsten Kukuk2015-08-281-4/+2
| | | | | | | | | | | | | | | | | | | TI-RPC is using select() in svc_run(), while glibc and Solaris are using poll(). This has two drawbacks: poll() is much more efficient then select(), and with select() we are limited to 1024 open filehandles. And applications replacing svc_run on Linux don't work, since they expect svc_pollfd and svc_max_pollfd. Attached patch changes this. It's full backward compatible, API and ABI, so e.g. current rpcbind will continue to work and compile. The only problem could arrive, that we can have more than 1024 open filehandles and applications ignoring higher ones.

* Remove vestiges of AUTH_KERBChuck Lever2015-06-162-196/+0
| | | | | | | | | | | | | | | | | AUTH_KERB is described only briefly in the ONC+ Developer's Guide. However, xdr_authkerb_cred(), for example, is declared in Linux's tirpc/rpc/auth.h, but does not appear in Solaris 11's RPC headers. It is not provided by glibc, so there isn't any backward compatibility requirement. The libtirpc implementation of AUTH_KERB here on Linux and in FreeBSD seems to be incomplete and inoperative. Seems like the scattered pieces of it can be removed safely. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | When --enable-gss is specified on the ./configure command line, have the library automatically register server-side support for the RPCSEC_GSS auth flavor. The complication is that specific interaction is required with the RPC client if GSS authentication fails. GSS authentication sometimes has to squelch the normal reply done by svc_getreq(), and substitute its own. _svcauth_gss() already has a boolean argument to do this. But _authenticate() is an official API (see rpc/svc_auth.h). We can't alter its synopsis. Instead of adding a "no_dispatch" argument to our existing _authenticate() API, preserve its synopsis for backwards compatibility, and introduce a second external authentication API for the dispatcher. This matches a similar API change done in the Solaris libtirpc. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
