* Increase the size of the send and receive buffers for YP client rpcKonstantin Belousov2019-09-161-1/+1
| | | | | | | | | | | | | | | | | | | calls to max allowed UDP datagram size. Since max allowed size both for keys and values where increased, the old sizes of around 1K cause ypmatch(3) failures, while plain maps fetches work. The buffers were reduced in r34146 from default UDP rpcclient values to 1024/2304 due to the key and value size being 1K.

* libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-252-2/+6
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified 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. Notes: svn path=/head/; revision=326193

The ypmatch(1) will return an error until the command receives an kill(1).

* libc: Use O_CLOEXEC for various internal file descriptors.Jilles Tjoelker2012-09-291-1/+1
| | | | | | | | | | | | This fixes a race condition where another thread may fork() before CLOEXEC is set, unintentionally passing the descriptor to the child process. This commit only adds O_CLOEXEC flags to open() or openat() calls where no fcntl(fd, F_SETFD, FD_CLOEXEC) follows. The separate fcntl() call still leaves a race window so it should be fixed later.

| | | | | | | | | | | | | | | | | | | | | | | | | | packet loss when talking to a NIS server. - Set 1 second retry timeout to further realistically handle UDP packet loss for yp_next packet bursts. If the packet hasn't come back within 1 second its rather unlikely to come back at all. There is still back-off mechanism in RPC so if there is another reason than packet loss for the lack of response within 1 second, the NIS server will not be totally bombarded with requests. This reduces the risk of NIS failing with: yp_next: clnt_call: RPC: Timed out considerably. This is mainly a problem if you have larger NIS maps (like at FreeBSD.org) since enumerations of the lists will cause a UDP packet bursts where a few packets being lost once in a while do happen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix resource allocation problems:Bill Paul1998-03-071-94/+176
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Completely recoded the ypmatch cache code. The old code could leak memory: it would allow the cache to grow, but never shrink. The new code imposes the following limits: o The cache is capped at a limit of 5 entries. o Each entry expires after five seconds, at which point its slot is freed. o If an insertion is to be done and all five slots are filled, the oldest entry is forcibly expired to release its slot. Also, the cache is implemented on a per-binding basis rather than having a global cache covering all bindings. This means that each bound domain has its own 5 slot cache. - Changed clntudp_create() to clntudp_bufcreate() so that the xmit/recv message buffer sizes can be set explicitly. NIS transactions are rarely much larger than 1024 bytes since YPMAXRECORD is 1024. The defaults chosen by clntudb_create() are actually much larger than needed. I set the xmit buffer to a little over 1024 and the recv buffer to a little over 2048. This saves a few Kbytes for each NIS binding. - Add my name to the copyright. I think I've made enough changes to this file to merit it. :) Note: these changes should go into the 2.2.x branch, but I'm waiting on feedback from a tester to see if the cache fixes solve the reported memory leak problem.

* Fix for bug noticed by Christoph Kukulies.Bill Paul1996-12-201-2/+3
| | | | | | | | | | | | | | | | | | | _yp_dobind() checks to see if a fork() happens (by checking PIDs) and invalidates all bindings if it finds itself in a newly created child process. (This avoids sharing RPC client handles and socket descriptors with the parent, which would be bad.) Unfortunately, it summarily calls clnt_destroy() on the handles, which may result in the destruction of a descriptor that isn't really a socket. This is fixed by replacing the explicit call to clnt_destroy() with a call to _yp_unbind(), which deals with potentially hosed socket descriptors an a safe manner. This is basically a one-liner. Once I confirm that it fixes Christoph's problem, I'd like permission to put it in the 2.2-RELENG branch. Notes: svn path=/head/; revision=20716

Note that we do not check the ypserv port returned to us from ypbind. It is assumed that ypbind has already done a reserved port test (or not, depending on whether or not it was started with -s); if we trust the authenticity of the local ypbind, we should also trust its judgement.
