[I] A reliable replacement for Glibc's nscd
|
||
|
|
|
||
|
|
[T] Nscd is a daemon that provides a cache for the most common name service
|
||
|
|
[T] requests.
|
||
|
|
[T]
|
||
|
|
[T] As designed, nscd is a multithreaded program which calls NSS libraries.
|
||
|
|
[T] These libraries are not part of libc, they may be provided
|
||
|
|
[T] by third-party projects (samba, ldap, you name it).
|
||
|
|
[T] Thus nscd cannot be sure that libraries it calls do not have memory
|
||
|
|
[T] or file descriptor leaks and other bugs.
|
||
|
|
[T]
|
||
|
|
[T] Since nscd is multithreaded program with single shared cache,
|
||
|
|
[T] any resource leak in any NSS library has cumulative effect.
|
||
|
|
[T] Even if an NSS library leaks a file descriptor 0.01% of the time,
|
||
|
|
[T] this will make nscd crash or hang after some time.
|
||
|
|
[T]
|
||
|
|
[T] Of course bugs in NSS .so modules should be fixed, but meanwhile
|
||
|
|
[T] we do want nscd which does not crash or lock up.
|
||
|
|
[T]
|
||
|
|
[T] unscd is a single-threaded server process which offloads all NSS
|
||
|
|
[T] lookups to worker children (not threads, but fully independent
|
||
|
|
[T] processes). Cache hits are handled by parent. Only cache misses
|
||
|
|
[T] start worker children. This design is immune against resource leaks
|
||
|
|
[T] and hangs in NSS libraries. It is also many times smaller and it
|
||
|
|
[T] emulates glibc nscd pretty closely.
