* MFC r313563: kldxref: bump MAXSEGS to 3emaste2017-02-171-1/+1
| | | | | | | | ld.bfd generates two PT_LOAD segments, but certain linkers or linker configurations generate three PT_LOAD segments (one additional for RELRO). PR: 216975
* MFC r313562: kldxref: s/sections/segments/ in warning messageemaste2017-02-171-1/+1
| | | | | | The message refers to program header segments, not sections. PR: 216975
* MFC r288490: Add debug file extension to kldxref(8)emaste2016-04-221-1/+4
| | | | | | | | | | | | | After r288176 [in head] kernel debug files have the extension .debug. They also moved [in head] to /usr/lib/debug/boot/kernel by default so in the normal case kldxref does not encounter them. A src.conf(5) setting may be used to continue installing them in /boot/kernel though, so have kldxref skip .debug files in addition to .symbols files. Merged this change to avoid warnings when a stable/10 kldxref runs against a head install, perhaps on an upgrade to 11-CURRENT. The change to kernel debug files will not be merged to stable/10.
* MFC r277205 (imp):emaste2016-04-221-0/+4
| | | | | | | | | Reserve and ignore the a new module metadata type MDT_PNP_INFO for associating an optional PNP hint table with this module. In the future, when these are added, these changes will silently ignore the new type they would otherwise warn about. It will always be safe to ignore this data. Get this into the builds today for some future proofing.
* MFC r275940 (imp): Bump the largest record we can cope with from 1k to 8k.emaste2016-04-221-1/+1
| | | | | Other users of the hints file don't have any real limits, and longer records will need to be written shortly.
* MFC r265157: kldxref: Clean up error reportingemaste2014-07-231-8/+9
| | | | | | | | | | | | | Omit "too many sections" warnings if the ELF file is not dynamically linked (and is therefore skipped anyway), and otherwise output it only once. An errant core file would previously cause kldxref to output a number of warnings. Also introduce a MAXSEGS #define and replace literal 2 with it, to make comparisons clear.

* kldxref: Do not depend on the directory order.jilles2013-10-041-1/+11
| | | | | | | | | | | | | | | | Sort the filenames to get a consistent result between machines of the same architecture. Also, sort FTS_D entries after other entries so kldxref -R works properly in the uncommon case that a directory contains both subdirectories and modules. Previously, this may have happened to work, depending on the order of files in the directory.

* Change maketempfile() to return a FILE* so as to eliminate the fopen()marcel2006-07-291-6/+7

This also fixes the invalid mode used on the fopen(). While here, assign NULL to fxref after fclose() because we test for fxref being !NULL to determine if we have the (temporary) hints file open.
