* Eliminate internal fixed-width type wrappersGreg Hudson2014-02-261-17/+14
| | | | | Directly use stdint.h names for integer types in preference to the various internal names we have made up for them.
* Assume <stdint.h> and fixed-width typesGreg Hudson2014-02-261-36/+3
| | | | | | | Make unconditional use of <stdint.h> and fixed-width types such as uint32_t. k5-plugin.h doesn't use any special integer types, so remove the conditional include block there. Nothing uses INT64_FMT/UINT64_FMT, so leave those out of k5-platform.h for now.
* Make set_cloexec_fd return voidBen Kaduk2013-11-041-10/+7
| | | | | | | | | We never check its return value (causing clang to emit warnings), and its use is primarily in cases where we should continue processing in the event of failure. Just ignore errors from the underlying fcntl() call (if present) and treat this operation as best-effort. The #if 0 code should probably be removed.
* Add an internal constant-time comparison functionGreg Hudson2013-10-031-0/+8
| | | | | | | k5_bcmp acts similarly to the deprecated Unix bcmp() function, returning zero if two memory regions are equal and nonzero if they are not. It is implemented such that it should take the same amount of time regardless of how many bytes are equal within the memory regions.
* Fix windows buildBen Kaduk2013-02-251-1/+1
| | | | | | | | | | Catch up to the split of preauth_plugin.h into client and kdc specific portions. While here, use copy's /y flag to suppress an override-confirmation prompt (though we do not list any dependencies for this target at the moment, so no such prompt will be generated). Do not disable library finalizers for windows, erroneously disabled in 4538146e1452e0966164119cefb0804993ce6bbb.
* Don't finalize libraries in static buildGreg Hudson2012-12-121-11/+13
| | | | | | | | | | | | In a build with static libraries, functions tagged with __attribute__((destructor)) may be executed in any order, not in a topologically sorted order as they are in shared libraries. This could result in libcom_err functions being invoked (from another library's finalizer) after libcom_err has been finalized, which would (at minimum) result in using a mutex after it is destroyed. To prevent this kind of problem, disable finalizers in the static build regardless of whether we have compiler or linker support for them. Reported by Mihai Serban <mihai.serban@gmail.com>.
* Add internal JSON encoding and decoding supportGreg Hudson2012-09-111-0/+6
| | | | Add JSON support based loosely on Heimdal's heimbase code.
* Allow using locales when gettext is absentBen Kaduk2012-07-061-5/+3
| | | | | | | | | | | Previously, if configure did not detect dgettext(), we disabled anything that smelled like localization, inadvertently including setlocale(). Now that we use setlocale(LC_ALL, ""), we have localized dates available as well as messages, so we should not disable calls to setlocale() any more. Since the routines from locale.h are only used in a relatively small number of places, just include the header directly in those files and remove it from k5-platform.h.
* Add no-op macro for ngettext for non-NLS buildsGreg Hudson2012-05-091-0/+1
| | | | | | | r25857 (#7128) uses ngettext, which means we need a no-op macro for it when we're building without NLS support. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25859 dc483132-0cff-0310-8789-dd5450dbe970
* Ensure termination in Windows vsnprintf wrapperGreg Hudson2011-10-181-1/+3
| | | | | | | | | | | | | | | The Windows _vsnprintf does not terminate its output buffer in the overflow case. Make sure we do that in the wrapper. Reported by Chris Hecker. (Not an issue for KfW 3.2 since we weren't using snprintf in 1.6.x except in Unix-specific code.) ticket: 6980 target_version: 1.10 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25367 dc483132-0cff-0310-8789-dd5450dbe970
* Add krb5int_gettimeofday to k5sprt for platforms w/o native gettimeofdaySam Hartman2011-10-051-0/+5
| | | | | | | | | | Microsecond accuracy on _WIN32, but only one second accuracy on other, AFAIK purely hypothetical, platforms that lack native gettimeofday. Shamelessly cribbed from Heimdal.

* Add internal APIs for portable path manipulationGreg Hudson2011-08-071-0/+22
| | | | | | | | | | | | | k5_path_split separates a path into dirname and basename. k5_path_join joins two paths. k5_path_isabs determines if a path is absolute. All three functions follow the Python path function semantics. Currently the test module doesn't run in the Windows build, but the Windows path semantics are tested in the Unix build using specially built objects. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25074 dc483132-0cff-0310-8789-dd5450dbe970

* Set close-on-exec flag in most places where file descriptors areKen Raeburn2007-10-221-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | opened in our libraries (in case another application thread spawns a new process) and in the KDC programs (in case a plugin library spawns a new process). Checked calls to: open fopen THREEPARAMOPEN mkstemp socket accept dup dup2 pipe. In: util lib plugins kdc kadmin/server krb524. The various programs are less critical than the libraries, as any well-written plugin that spawns a new process should close all file descriptors it doesn't need to communicate with the new process. This approach also isn't bulletproof, as the call to set the close-on-exec flag is necessarily a separate call from creating the file descriptor, and the fork call could happen in between them. So plugins should be careful regardless of this patch; it will only reduce the window of potential lossage should a plugin be poorly written. (AFAIK there are currently no plugins that spawn processes where this would be a problem.)

* provide asprintf functionality for internal useKen Raeburn2007-06-201-3/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I plan to use asprintf in some gssapi error-message management routines, so let's make sure we have the functionality available, implementing it locally if necessary. This implementation assumes vsnprintf is available, an assumption that the support library is already making at the moment. Since this implementation requires calling vsnprintf potentially multiple times with the same va_list, use va_copy if it's available, or provide a hack version (which should work okay if va_list is a scalar or array type that requires no other special handling, and if va_end does nothing interesting, which is usually the case) if the compiler doesn't provide it. I also changed a couple bits of code to use asprintf, to make sure we exercise our implementation in testing. (C99 requires vsnprintf and va_copy; vasprintf is a GNU/BSD extension, but an oh so useful one....) * configure.in: Check for va_copy, or if va_list objects can be simply assigned. Define HAS_VA_COPY and CAN_COPY_VA_LIST as appropriate. * include/k5-platform.h: Define a va_copy macro if the compiler doesn't provide it. * include/k5-platform.h: If vsnprintf isn't available from the OS, abort compilation.
