* Implement ZDumpSession and ZLoadSessionGravatar David Benjamin2013-09-28
| | | | This is unlikely to ever get merged, but it'll be handy for roost.
* Use the saved session keys in ZCheckZcodeAuthenticationGravatar David Benjamin2013-09-28
| | | | | | | | | | | | | | | | | This allows for authentication checking to continue working even when tickets expire or are renewed. Also include key expiration logic. This is possibly overly conservative and paranoid by a couple orders of magnitude. Intentionally do not use SERVACK because they're mildly annoying to get at and aren't authenticated. When we receive a notice authenticated with a key, we know the server has received it. From there, we can infer that sufficiently old keys are stale. We can't remove stale keys immediately because some older notices may still be in flight, but after a grace period they can go. The timeout is set to 60 seconds, which is fairly high, but matches Z_ReadWait's timeout.
* Create an alternate Z_AuthProc that saves keysGravatar David Benjamin2013-09-28
| | | | | | | The start of proper session key management in libzephyr. A new Z_AuthProc is added which appends the key into a queue. ZSubscribeTo and ZSubscribeToSansDefaults are modified to use it. For now, it's extremely simple and makes no attempt to expire old keys.
* Add internal Z_MakeZcodeAuthentication functionGravatar David Benjamin2013-09-28
| | | | Explicitly takes a krb5_creds as input.
* Bump find_or_insert_uid's time limitGravatar David Benjamin2013-09-28
| | | | | | | Basing it on krb4's CLOCK_SKEW value doesn't make any sense. We pick 900 because it is just over 128 + 256 + 512, the longest group of three timeouts in the retransmit schedule used by the zephyrd. This allows us to miss two packets in a row and still be fine.
* Expose Z_Subscriptions as ZSubscriptionsGravatar David Benjamin2013-08-08
| | | | | | With a custom send_routine that mirrors ZSrvSendList. This allows for an asynchronous version that replaces send_routine with non-blocking versions (and waits for ACKs out-of-band).
* zctl flush_subsGravatar Jeffrey Hutzelman2013-02-26
| | | | | | | | Provide a new zctl subcommand, flush_subs, to flush all subscriptions for a specified recipient. This is implemented using a new library function, ZFlushUserSubscriptions(). This is the client side of #103
* server: add CLIENT_FLUSHSUBS control messageGravatar Jeffrey Hutzelman2013-02-26
| | | | | | | | | This adds support to the server for a new client control message, CLIENT_FLUSHSUBS, which flushes all subscriptions and pending retransmits for clients belonging to a given principal. The target principal must be the same as the sender, unless the sender is on the opstaff ACL. This is the server side of #103
* Allow zctl flush_locs to take a user argumentGravatar Jeffrey Hutzelman2013-02-26
| | | | | | | | Provide a new library function, ZFlushUserLocations(), to flush locations for a specified user. This can be called using zctl flush_locs, which now takes an optional username parameter. This is the client side of #102
* Send IPv4 addresses ASCII-encoded in v4 bdumpsGravatar Jeffrey Hutzelman2013-02-17
| | | | This fixes #94
* 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.
* Retool our use of configure such that we track it like everyone else doesGravatar Karl Ramm2011-10-23
| | | | | i.e. don't keep generated or foreign stuff in our source tree. As a side effect, this lets us use a libtool, etc. from this century
