* MFdragonfly: resolver fix for timeouts on unqualified hostnamesNate Lawson2004-04-211-5/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | res_search only incremented got_servfail for h_errno == TRY_AGAIN *AND* hp->rcode == SERVFAIL. However, there are cases such as timeouts where rcode is not always set to SERVFAIL. This leads to inconsistent nameserver operation during multi-domain and truncated dot searches, especially during booting when portions of the network are being brought up simultanious with dns lookups. This patch attempts to correct the problem by unconditionally terminating the search if TRY_AGAIN is returned (after res_query has gone through all retries and name servers) instead of trying other domain elements in the domain seach path. This patch should fix reported problems (which I can reproduce) with some NFS mounts failing during boot. This occured because mount_nfs thought the host name lookup returned a definitive failure using a non-dotted host name when, in fact, it timed out on the first part (host.search.domain.name) and got a definitive host-not-found response on the second part (host.). Generally speaking, search path name server timeouts can exceed 60 seconds per element and most machines which consistently timeout on earlier portions of a search path are effectively non-operational due to the imposed delays. It is more important for DNS lookups to return the proper error code then to be able to recover a valid lookup in later portions of the search path in these situations.

| | | | | | | | | | | | | | | | | case where an /etc/nsswitch.conf file was present, but could not be opened (e.g. due to permissions). Previously, the open failure condition was suppressed, and the built-in defaults were used. In revision 1.11, however, propagated the open failure causing all nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs including getpwnam and gethostbyname unconditionally failed. This commit restores the previous behavior. Pointy hat: nectar (+1 for obstinance; ache had to use clue bat) Reported by: ache Notes: svn path=/head/; revision=127727
* When a dynamic NSS module is built and linked against a threadJacques Vidrine2004-03-302-22/+42
| | | | | | | | | | | | | | | | library, it may pull in that thread library at run time. If the process started out single-threaded, this could cause attempts to release locks that do not exist. Guard against this possibility by checking __isthreaded before invoking thread primitives. A similar problem remains if the process is linked against one thread library, but the NSS module is linked against another. This can only be avoided by careful design of the NSS module.

| | | | | | | | | | | | | | | | | | that this provokes. "Wherever possible" means "In the kernel OR NOT C++" (implying C). There are places where (void *) pointers are not valid, such as for function pointers, but in the special case of (void *)0, agreement settles on it being OK. Most of the fixes were NULL where an integer zero was needed; many of the fixes were NULL where ascii <nul> ('\0') was needed, and a few were just "other".

* Make the resolver(3) and many associated interfaces much more reentrant.Brian Feldman2004-02-2512-52/+277
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now with what should be totally reentrant, and h_errno values will now be preserved correctly, but this does not affect interfaces such as gethostbyname(3) which are still mostly non-reentrant. In all of these relevant functions, the thread-safety has been pushed down as far as it seems possible right now. This means that operations that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected still under global locks that getaddrinfo(3) defines, but where possible the locking is greatly reduced. The most noticeable improvement is that multiple DNS lookups can now be run at the same time, and this shows major improvement in performance of DNS-lookup threaded programs, and solves the "Mozilla tab serialization" problem. No single-threaded applications need to be recompiled. Multi-threaded applications that reference "_res" to change resolver(3) options will need to be recompiled, and ones which reference "h_errno" will also if they desire the correct h_errno values. If the applications already understood that _res and h_errno were not thread-safe and had their own locking, they will see no performance improvement but will not actually break in any way. Please note that when NSS modules are used, or when nsdispatch(3) defaults to adding any lookups of its own to the individual libc _nsdispatch() calls, those MUST be reentrant as well.

* It was reported that when using nss_ldap, getgrent(3) would behaveJacques Vidrine2004-01-091-8/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | incorrectly when encountering `large' groups (many members and/or many long member names). The reporter tracked this down to the glibc NSS module compatibility code (nss_compat.c): it would prematurely record that a NSS module was finished iterating through its database in some cases. Two aspects are corrected: 1. nss_compat.c recorded that a NSS module was finished iterating whenever the module reported something other than SUCCESS. The correct logic is to continue iteration when the module reports either SUCCESS or RETURN. The __nss_compat_getgrent_r and __nss_compat_getpwent_r routines are updated to reflect this. 2. An internal helper macro __nss_compat_result is used to map glibc NSS status codes to BSD NSS status codes (e.g. NSS_STATUS_SUCCESS -> NS_SUCCESS). It provided the obvious mapping. When a NSS routine is called with a too-small buffer, the convention in the BSD NSS code is to report RETURN. (This is used to implement reentrant APIs such as getpwnam_r(3).) However, the convention in glibc for this case is to set errno = ERANGE and overload TRYAGAIN. __nss_compat_result is updated to handle this case.
