* Clean up warningsGravatar Jeffrey Hutzelman2013-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate compiler warnings due to various issues (listed below). This allows Zephyr to build cleanly under GCC versions ranging from 4.1.0 to 4.7.2 with all of the options shown below: -g -O2 -Wall -Werror -Wno-deprecated-declarations -Wmissing-declarations -Wpointer-arith -Wstrict-prototypes -Wshadow -Wextra -Wno-missing-field-initializers -Wno-unused-parameter and, on recent versions, -Wunreachable-code Test builds were done - On Ubuntu 12.10 (Quantal Quetzal) using both MIT Kerberos 1.10.1 and Heimdal 1.6, without krb4 and both with and without C-Ares and Hesiod - On Fedora 14 using Heimdal 0.6, without C-Ares or Hesiod and both with and without krb4 (KTH Kerberos 1.3rc2) - On Fedora Core 3, Fedora Core 5, Fedora 7, and Fedora 10, using Heimdal 0.6 and without C-Ares, Hesiod, or krb4 It also allows clean builds on Solaris 10 under the Sun Studio 12 (9/07) C compiler with the following options: -g -fd -v -errfmt -errhdr=%user -errtags=yes -errwarn=%all -erroff=E_OLD_STYLE_FUNC_DECL,E_ENUM_TYPE_MISMATCH_ARG,E_ARG_INCOMPATIBLE_WITH_ARG ... and under Solaris 9 with the Sun Forte 7 (3/02) C compiler with the above options and -erroff=E_FUNC_HAS_NO_RETURN_STMT. Solaris builds were done with Heimdal 0.6 and without C-Ares, Hesiod, or krb4. The following types of issues are addressed in this change: - Parameters and local variables with the same names as library functions - Parameters and local variables with the same names as globals - Declarations for exported global variables missing from headers - Prototypes for exported functions missing from headers - Missing 'static' on functions that shouldn't be exported - Old-style function declarations - Duplicate declarations - Type mismatches - Unused variables and functions - Uninitialized variables - Forward references to enums - Necessary header files not included - Violations of the aliasing rules, where GCC was able to detect them - Missing braces on if blocks that might be empty - Attempts to do pointer arithmetic on pointers of type void *, which is not permitted in standard C. - An attempt to pass a function pointer via a void * parameter, which is not permitted in standard C. Instead, we now pass a pointer to a structure, which then contains the required function pointer. - Unnecessary inclusion of <krb5_err.h>, which is already included by <krb5.h> when the former exists, and might not be protected against double inclusion, depending on which com_err was used. - Missing include of <com_err.h>, which was masked by the fact that it is included by headers generated by e2fsprogs compile_et - Use of com_err() with a non-constant value in place of the format string, which in every case was a fixed-size buffer in which a message was built using sprintf(!). Both the calls to sprintf and the fixed-size buffers have been removed, in favor of just letting com_err() do the formatting. - Various cases where X library functions expecting a parameter of type wchar_t * were instead passed a parameter of type XChar2b *. The two types look similar, but are not the same and are _not_ interchangeable. - An overly-simplistic configure test which failed to detect existence of <term.h> on Solaris, due to not including <curses.h>. - Using the wrong type for the flags output of krb5_auth_con_getflags() when building against Heimdal. A configure test is added to detect the correct type.
* znol: watch foreign users in their own realmGravatar Derrick Brashear2012-11-24
| | | | | | | | | If we want to receive login/logout notices for a user in another realm, we need to subscribe to them in that realm. Extracted from Andrew zephyr/058, which reverts a change to client-side interrealm support that was inadvertently introduced when importing new code from Athena.
* zwrite: Replace outgoing default format with a small URLGravatar Geoffrey Thomas2012-11-24
| | | | | | We need the bytes, no modern client uses it, and it's inherently a security vulnerability. For those clients that do use it, provide a link to a page on the zephyr wiki that explains the issue.

| | | | | | | | | | Rearrange what libraries get pulled in where, so dpkg-shlibdeps doesn't whine (see a theme here?) (Also so that, say, znol, doesn't have to link with Everything.) This will break platforms that don't do shared-library dependencies.
