It will shave a few bytes +off them. + + +* Customization + ------------- + + You can customize paths via flags given to configure. + See ./configure --help for a list of all available configure options. + + +* Environment variables + --------------------- + + Controlling a build process via environment variables is a big and +dangerous hammer. You should try and pass flags to configure instead; +nevertheless, a few standard environment variables are recognized. + + If the CC environment variable is set, its value will override compiler +detection by configure. The --host=HOST option will still add a HOST- +prefix to the value of CC. + + The values of CFLAGS, CPPFLAGS and LDFLAGS will be appended to flags +auto-detected by configure. To entirely override the flags set by +configure instead, use make variables. + + +* Make variables + -------------- + + You can invoke make with a few variables for more configuration. + + CC, CFLAGS, CPPFLAGS, LDFLAGS, LDLIBS, AR, RANLIB, STRIP, INSTALL and +CROSS_COMPILE can all be overridden on the make command line. This is +an even bigger hammer than running ./configure with environment +variables, so it is advised to only do this when it is the only way of +obtaining the behaviour you want. + + DESTDIR can be given on the "make install" command line in order to +install to a staging directory. + + +* Shared libraries + ---------------- + + Software from skarnet.org is small enough that shared libraries are +generally not worth using. Static linking is simpler and incurs less +runtime overhead and less points of failure: so by default, shared +libraries are not built and binaries are linked against the static +versions of the skarnet.org libraries. Nevertheless, you can: + * build shared libraries: --enable-shared + * link binaries against shared libraries: --disable-allstatic + + +* Static binaries + --------------- + + By default, binaries are linked against static versions of all the +libraries they depend on, except for the libc. You can enforce +linking against the static libc with --enable-static-libc. + + (If you are using a GNU/Linux system, be aware that the GNU libc +behaves badly with static linking and produces huge executables, +which is why it is not the default. Other libcs are better suited +to static linking, for instance musl: http://musl-libc.org/. If +you're using nsss, chances are you're running musl, or a similar +libc, anyway.) + + +* Cross-compilation + ----------------- + + skarnet.org packages centralize all the difficulty of +cross-compilation in one place: skalibs. Once you have +cross-compiled skalibs, the rest is easy. + + * Use the --host=HOST option to configure, HOST being the triplet +for your target. + * Make sure your cross-toolchain binaries (i.e. prefixed with HOST-) +are accessible via your PATH environment variable. + * Make sure to use the correct version of skalibs for your target, +and the correct sysdeps directory, making use of the +--with-include, --with-lib, --with-dynlib and --with-sysdeps +options as necessary. + + +* The slashpackage convention + --------------------------- + + The slashpackage convention (http://cr.yp.to/slashpackage.html) +is a package installation scheme that provides a few guarantees +over other conventions such as the FHS, for instance fixed +absolute pathnames. skarnet.org packages support it: use the +--enable-slashpackage option to configure, or +--enable-slashpackage=DIR for a prefixed DIR/package tree. +This option will activate slashpackage support during the build +and set slashpackage-compatible installation directories. +If $package_home is the home of the package, defined as +DIR/package/$category/$package-$version with the variables +read from the package/info file, then: + + --dynlibdir is set to $package_home/library.so + --bindir is set to $package_home/command + --sbindir is also set to $package_home/command (slashpackage +differentiates root-only binaries by their Unix rights, not their +location in the filesystem) + --libexecdir is also set to $package_home/command (slashpackage +does not need a specific directory for internal binaries) + --libdir is set to $package_home/library + --includedir is set to $package_home/include + + --prefix is pretty much ignored when you use --enable-slashpackage. +You should probably not use both --enable-slashpackage and --prefix. + + When using slashpackage, two additional Makefile targets are +available after "make install": + - "make update" changes the default version of the software to the +freshly installed one. (This is useful when you have several installed +versions of the same software, which slashpackage supports.) + - "make -L global-links" adds links from /command and /library.so to the +default version of the binaries and shared libraries. The "-L" option to +make is necessary because targets are symbolic links, and the default make +behaviour is to check the pointed file's timestamp and not the symlink's +timestamp. + + +* Absolute pathnames + ------------------ + + You may want to use fixed absolute pathnames even if you're not +following the slashpackage convention: for instance, the Nix packaging +system prefers calling binaries with immutable paths rather than rely on +PATH resolution. If you are in that case, use the --enable-absolute-paths +option to configure. This will ensure that programs calling binaries from +this package will call them with their full installation path (in bindir) +without relying on a PATH search. + + +* Out-of-tree builds + ------------------ + + skarnet.org packages do not support out-of-tree builds. They +are small, so it does not cost much to duplicate the entire +source tree if parallel builds are needed. diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..36b6402 --- /dev/null +++ b/Makefile @@ -0,0 +1,154 @@ +# +# This Makefile requires GNU make. +# +# Do not make changes here. +# Use the included .mak files. +# + +it: all + +make_need := 3.81 +ifeq "" "$(strip $(filter $(make_need), $(firstword $(sort $(make_need) $(MAKE_VERSION)))))" +fail := $(error Your make ($(MAKE_VERSION)) is too old.

nsss

+ +

What is it ?

+ +

+ nsss is an implementation of a subset of the pwd.h, +group.h and shadow.h family of functions, +performing user database access on Unix systems. +

+ +

+ Usually, user database access via getpwnam() and similar +function is provided by the system's libc. However, not all libcs implement +a configurable backend for the user/group database. For instance the +musl libc, on Linux, only supports +the standard /etc/passwd mechanism; it also supports the +nscd protocol but this is not quite enough to implement the +full set of database access functions with certain backends (such as a +LDAP server). +

+ +

+ nsss is a secure implementation of configurable user/group/shadow +database access, providing getpwnam() et al. functionality +by communicating over a Unix domain socket with a daemon; the daemon +can perform lookups in any database it chooses. +

+ +

+ Unlike NSS, nsss does not perform dynamic module +loading, only adds a small footprint to the application's binary, +and does not add any complex decision engine into the client's address +space. Applications can be statically linked against the nsss +library, and still benefit from configurable user database access +functions. +

+ +

+ +

The nsss library interface

+ +

General information

+ +

+ libnsss is a client library meant to be used by client +programs needing utmp functionality. It interacts with various +server-side daemons such as +nsssd-unix. +

+ +

+ Application programs can use it directly, but most existing programs +simply use the standard +pwd.h, +grp.h or +shadow.h +interfaces, which in nsss are implemented as a series of thin wrappers +around the nsss library. +

+ +

Compiling

+ +
    +
  • Make sure the nsss headers, as well as the skalibs headers, +are visible in your header search path.
    • +
  • Use #include <nsss/nsss.h>
    • +
  • To use the standard pwd.h interface, you can +just #include <pwd.h>, which will work as long +as the nsss/pwd.h header is accessible in your header +search path.
    • +
  • Same thing for grp.h and shadow.h.
    • +
+ +

Linking

+ +
    +
  • Make sure the nsss library, as well as the skalibs library, +are visible in your library search path.
    • +
  • Link against -lnsss, -lskarnet,
    • +`cat $SYSDEPS/socket.lib` and +`cat $SYSDEPS/tainnow.lib`, $SYSDEPS being your skalibs +sysdeps directory. +
+ +

Programming

+ +

+ The nsss/nsss.h header is actually a collection of headers: +

+ +
    +
  • nsss/nsss-unix.h implements basic access to the +/etc/passwd, /etc/group and /etc/shadow +database.
    • +
  • nsss/nsss-switch.h implements connection via a Unix +domain socket to a listening nsssd daemon, implementing an +authentication backend based on what implementation of +the daemon is listening.
    • +
  • nsss/nsss-all.h implements a safe policy: first a +connection via nsss-switch is attempted, and if no daemon +is listening, the safe nsss-unix backend is used.
    • +
+ +

+ By default, the getpwnam() et al. functions are aliased +to their nsss-all implementations. You can disable the +nsss-unix fallback by compiling with the NSSS_DISABLE_UNIX +macro defined (-DNSSS_DISABLE_UNIX). Or you can disable any +attempt to connect to a daemon by compiling with the +NSSS_DISABLE_SWITCH macro defined (-DNSSS_DISABLE_SWITCH). +

+ +

An overview of nsss

+ +

+ nsss is a secure implementation of a subset of the +pwd.h, grp.h and shadow.h functionality, i.e. +user authentication on Unix systems. It includes full POSIX +functionality, a few GNU extensions, and an underlying +C client library with better error reporting +than the POSIX interface specifies. +
