* Include autoconf.h before system headersGreg Hudson2014-07-081-2/+2
| | | | | | | | | Include autoconf.h (either directly or via proxy) before system headers, so that feature test macros defined there can affect the system namespace. Where include order was changed, eliminate some redundant or unnecessary includes. ticket: 7961
* make dependGreg Hudson2013-01-101-1/+1

* Avoid null dereference in BDB dbtree error caseGreg Hudson2012-12-201-3/+3
| | | | | | | | | An error case in __bt_first would deference a null pointer. This is an old upstream BDB bug. Use a separate variable to hold the result of mpool_get() until it has been checked. Reported by Nickolai Zeldovich <nickolai@csail.mit.edu>. ticket: 7511

* Rename db2 header files db.h and db-config.h in the source tree, soKen Raeburn2009-08-211-53/+33
| | | | | | | | | | | | | | | | | that there will always be only one version of each name in the include path (namely, the copy made in the build tree, or the generated db.h if not using the in-tree one). This should fix some minor problems with different dependency lists generated on different systems. Sort and uniquify dependency header names before doing substitutions, as well as after. Look for the db2 headers listed in sorted order. Don't copy db-ndbm.h into the build tree; let libdb2 find it from the source tree only. Update dependencies. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@22572 dc483132-0cff-0310-8789-dd5450dbe970

* move generated dependencies out of Makefile.inKen Raeburn2009-01-052-78/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Move automatically-generated dependencies into separate files in the source tree, and take the data out of Makefile.in. Keep the "make depend" rules for stripping out the dependencies from Makefile.in, in case some optional directories were missed, but everything that builds on my UNIX build has been converted. (Converting a directory just requires creating an empty "deps" file so that config.status can build the makefile, and then later running "make depend" in that directory to get the correct content for it.) Change configure scripts to incorporate the "deps" file when building each Makefile. This change requires the existence of a file "deps" in each source directory where we build a makefile, even if there are no sources for which to compute dependencies; a switch to GNU make would let us conditionalize that, but we can assess that later. Update dependencies for the generate Makefile itself to list the deps file. This will also require some minor tweaking of the Windows build, to make it incorporate the new deps file. ticket: new git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@21701 dc483132-0cff-0310-8789-dd5450dbe970

* more tests for libdb btree page split on zero indexTom Yu2008-02-071-1/+2
| | | | | | | | | | | | | | | | | | | | Enhance btree debugging output somewhat to limit key printout to the key length if the key is not null-terminated. Add additional test case for the zero-index page split bug; test case can create a corrupted btree database with records unreachable by random access but reachable by sequential access. Requires recompiling with CPPFLAGS='-DDEBUG -DDEBUG_IDX0SPLIT' to correctly model mpool page reuse that would be present in production conditions. (CPPFLAGS=-DDEBUG would otherwise explicitly overwrite the contents of reused pages.) ticket: new target_version: 1.6.4 tags: pullup component: krb5-kdc git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@20222 dc483132-0cff-0310-8789-dd5450dbe970
* libdb btree page split on zero index corrupts dbTom Yu2008-02-011-2/+2
| | | | | | | | | | | | | | | | | | | | Splitting a btree page on index 0 can corrupt the database if the key length plus data length is exactly a certain value. This certain size causes the item to get the left page to itself, and causes the right page to contain an erroneous additional index "hole" having an uninitialized value. This bug may be one of the remaining causes of unexplained database corruption reported over the years. Shawn Emery provided useful data from actual instances of this corruption. Add a test case for this bug. (Raw libdb test rather than kdb; the latter would be much harder.) ticket: new target_version: 1.6.4 tags: pullup component: krb5-kdc git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@20214 dc483132-0cff-0310-8789-dd5450dbe970
* Set close-on-exec flag in most places where file descriptors areKen Raeburn2007-10-222-46/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.) Update dependencies. ticket: 5561 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@20143 dc483132-0cff-0310-8789-dd5450dbe970
