* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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. No functional change intended.

When no -h is specified, the sizeof(ai_addr) is used, which is always smaller than the required size and therefore uaddr would be NULL, causing the kernel to copyin() from userland NULL and fail with EFAULT.

At one point it checks for a numeric address and if it sees one, it sets a hint parameter to force getaddrinfo to interpret the host as a numeric address. However that hint is not cleared for subsequent iterations of the loop and if any hosts seen after this point are host names, getaddrinfo will fail on the name. The result of this bug is that you cannot pass a host name to the -h flag. Unfortunately, the first iteration will either process ::1 or 127.0.0.1, so the flag is set on the first iteration and all host names will fail to be processed. The same bug applies to rpc.lockd and rpc.statd, so fix them too. Differential Revision: https://reviews.freebsd.org/D1507 Reported by: Dylan Martin MFC after: 1 week Sponsored by: Sandvine Inc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | fail with "bind: address already in use". This problem was reported to the freebsd-stable@ mailing list on Feb. 19 under the subject heading "statd/lockd startup failure" by george+freebsd at m5p dot com. The problem is that the first combination of {udp,tcp X ipv4,ipv6} would select a port# dynamically, but one of the other three combinations would have that port# already in use. The patch is somewhat involved because it was requested by dougb@ that the four combinations use the same port# wherever possible. The patch splits the create_service() function into two functions. The first goes as far as bind(2) in a loop for up to GETPORT_MAXTRY - 1 times, attempting to use the same port# for all four cases. If these attempts fail, the last attempt allows the 4 cases to use different port #s. After this function has succeeded, the second function, called complete_service(), does the rest of what create_service() did. The three daemons mountd, rpc.lockd and rpc.statd all have a create_service() function that is patched in a similar way. However, create_service() has non-trivial differences for the three daemons that made it impractical to share the same functions between them.

* Add the new kernel-mode NFS Lock Manager. To use it instead of theDoug Rabson2008-03-262-17/+257
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | user-mode lock manager, build a kernel with the NFSLOCKD option and add '-k' to 'rpc_lockd_flags' in rc.conf. Highlights include: * Thread-safe kernel RPC client - many threads can use the same RPC client handle safely with replies being de-multiplexed at the socket upcall (typically driven directly by the NIC interrupt) and handed off to whichever thread matches the reply. For UDP sockets, many RPC clients can share the same socket. This allows the use of a single privileged UDP port number to talk to an arbitrary number of remote hosts. * Single-threaded kernel RPC server. Adding support for multi-threaded server would be relatively straightforward and would follow approximately the Solaris KPI. A single thread should be sufficient for the NLM since it should rarely block in normal operation. * Kernel mode NLM server supporting cancel requests and granted callbacks. I've tested the NLM server reasonably extensively - it passes both my own tests and the NFS Connectathon locking tests running on Solaris, Mac OS X and Ubuntu Linux. * Userland NLM client supported. While the NLM server doesn't have support for the local NFS client's locking needs, it does have to field async replies and granted callbacks from remote NLMs that the local client has contacted. We relay these replies to the userland rpc.lockd over a local domain RPC socket. * Robust deadlock detection for the local lock manager. In particular it will detect deadlocks caused by a lock request that covers more than one blocking request. As required by the NLM protocol, all deadlock detection happens synchronously - a user is guaranteed that if a lock request isn't rejected immediately, the lock will eventually be granted. The old system allowed for a 'deferred deadlock' condition where a blocked lock request could wake up and find that some other deadlock-causing lock owner had beaten them to the lock. * Since both local and remote locks are managed by the same kernel locking code, local and remote processes can safely use file locks for mutual exclusion. Local processes have no fairness advantage compared to remote processes when contending to lock a region that has just been unlocked - the local lock manager enforces a strict first-come first-served model for both local and remote lockers.
