* POSIX allows getpwnam_r and getpwuid_r to return 0 (success) even if theRuss Allbery2006-06-131-4/+6
| | | | | | | | | | | | | username or UID could not be found, in which case OUT will be set to NULL. Elsewhere, code assumes that if k5_getpwnam_r or k5_getpwuid_r returns 0, OUT is non-NULL. Check whether OUT is NULL and adjust the return value accordingly in the k5_getpw{nam,uid}_r wrappers.

| | | | | | | | | | | | | | | | | | | stores of values. (E.g., on x86, gcc will emit a word load or store regardless of alignment; on sparc or alpha, it will do aligned word accesses. The old C code does byte operations and arithmetic, always.) Tested in crypto code on x86, sparc, and amd64. * k5-platform.h (load_*): Change argument type to point to const. (K5_BE, K5_LE): New macros, defined based on architecture macros for certain big-endian and little-endian platforms, respectively. (PUT, GET) [__GNUC__]: New macros. Use GCC's packed-structure support to do unaligned loads and stores. (PUTSWAPPED, GETSWAPPED) [__GNUC__]: Similar, but invoke a SWAP<size> macro (not defined yet) to swap the bytes of the value. (store_*, load_*): Use these macros when using GCC, depending on endianness and availability of the SWAP<size> macros. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17232 dc483132-0cff-0310-8789-dd5450dbe970
* don't always require support library when building with sun ccKen Raeburn2005-06-071-22/+25
| | | | | | | | | | | | | | | | | | | By default, a non-GCC configuration will not optimize during the build. The Solaris C compiler will always output functions defined as "inline", at least when not optimizing, even if they're never used. With recent changes on the trunk, k5_call_init_function will cause the support library to be required on Solaris by every program that includes k5-platform.h. This patch should fix that. * k5-platform.h (MAYBE_DEFINE_CALLINIT_FUNCTION) [DELAY_INITIALIZER]: New macro. If not __GNUC__, define k5_call_init_function in the expansion; otherwise, do nothing. (MAKE_INIT_FUNCTION) [DELAY_INITIALIZER]: Use it. (k5_call_init_function): Don't define function form at top level. ticket: new git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17230 dc483132-0cff-0310-8789-dd5450dbe970

Run stricter tests on return types and numbers of arguments, and only define the C macros if these parameters can actually be determined. * k5-platform.h (k5_getpwnam_r, k5_getpwuid_r): New macros. ticket: 2982 status: open git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17155 dc483132-0cff-0310-8789-dd5450dbe970
* shared library support for HP-UX 10Ken Raeburn2005-03-251-7/+80
| | | | | | | | | | | | | | | | | | | | | | | Our somewhat outdated HP-UX support (which was targeted at HP-UX 10, not 11) does not have support for shared library initialization and finalization functions, nor for shared library export lists. The former was causing compilation failures unless shared library support was disabled. * include/k5-platform.h: Expand on init/fini comments some more. (MAKE_FINI_FUNCTION): Add an HP-UX specific variant that defines an auxiliary function fitting the signature of HP-UX 10 library combined initializer/finalizer functions. * config/lib.in (hpux10.exports): New target, constructed similar to osf1.exports but with HP-UX 10.x linker options, no initializers, and "errno" explicitly added to the export list. * shlib.conf (*-*-hpux*): Combine PICFLAGS setting with SHLIB_EXPFLAGS and LDCOMBINE setting. Add linker option "-c hpux10.exports" to LDCOMBINE. Set SHLIB_EXPORT_FILE_DEP to hpux10.exports. Set use_linker_fini_option. ticket: new git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17153 dc483132-0cff-0310-8789-dd5450dbe970

* Added support for library initialization and finalization, and verificationKen Raeburn2004-04-241-2/+249
| | | | | | | | | | | | | | | | | | | | | | | | | | | that the initializer completed successfully. Delay initialization on POSIX until the first "verification" call. Currently specific to a few platforms, but should still build on others without thread support enabled. Use it to finish creating (if necessary) and destroy mutexes, and free some other storage "permanently" allocated by libraries (currently, libkrb5 cache/keytab type registries only). Change initialization of static mutexes to a two-step operation, a static "partial" initializer and a "finish_init" routine called from a thread-safe environment like library initialization is assumed to be. POSIX will use the former, Windows will use the latter, and the debug support will check that *both* have been used. Added init/fini functions to com_err, profile, krb5, and gssapi libraries. (The profile library one may need to be removed later.) The existing ones, not thread-safe, are still around. Use weak symbol support if available to figure out if the pthread library has been linked in, and avoid calling certain routines if the C library stubs are known not to exist or work. Stub declarations for thread-specific data. Minor bugfixes, whitespace changes. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@16268 dc483132-0cff-0310-8789-dd5450dbe970
