| 2017-01-09 | Revert previous, it's a documented behavior and people might rely on it. | Martin Pieuchot | |
| Pointed by deraadt@ | |||
| 2017-01-09 | Stop and restart the watchdog timer when entering and leaving ddb(4). | Martin Pieuchot | |
| From Christian Ludwig. | |||
| 2016-10-18 | Add the examine /m format, "display in unsigned hex with character | Christian Weisgerber | |
| dump at the end of each line", which has always been documented but not implemented. Mostly from NetBSD, but I fixed the column alignment code. ok mlarkin@, pirofti@ | |||
| 2016-09-18 | - inline db_ctf_nsyms() into it's only caller. the value remains cached and | Jasper Lievisse Adriaanse | |
| won't change, so there's no reason to call it again. - remove explicit return from void function ok mpi@ | |||
| 2016-09-17 | rename ddb/db_ctf.h to sys/ctf.h which is the expected location for the public | Jasper Lievisse Adriaanse | |
| CTF bits. ok kettenis@ mpi@ | |||
| 2016-09-17 | move the .SUNW_ctf section name definition to exec_elf.h and document it in ↵ | Jasper Lievisse Adriaanse | |
| elf(5) feedback from guenther@ ok guenther@ kettenis@ | |||
| 2016-09-16 | teach ddb(4) about CTF. currently it only loads the CTF and uses it on amd64 | Jasper Lievisse Adriaanse | |
| to lookup the number of function parameters. however having this basic facility allows us to expand it's usage. currently hidden behind the (disabled) DDBCTF kernel option as some of the required tools are not available in base yet. in addition to that one also needs recent bootblocks that load the .SUNW_ctf kernel section. discussed with mpi@ over many a cider and ale in cambridge feedback and ok guenther@ mpi@ | |||
| 2016-09-16 | drop unneeded casting noise | Jasper Lievisse Adriaanse | |
| pointed out by guenther@ in a separate diff | |||
| 2016-09-04 | Introduce Dynamic Profiling, a ddb(4) based & gprof compatible kernel | Martin Pieuchot | |
| profiling framework. Code patching is used to enable probes when entering functions. The probes will call a mcount()-like function to match the behavior of a GPROF kernel. Currently only available on amd64 and guarded under DDBPROF. Support for other archs will follow soon. A new sysctl knob, ddb.console, need to be set to 1 in securelevel 0 to be able to use this feature. Inputs and ok guenther@ | |||
| 2016-09-03 | make intrace a volatile, while the compiler does the right thing still | Jasper Lievisse Adriaanse | |
| (no change in the generated code), it's more correct and helps the reader. ok deraadt@ guenther@ | |||
| 2016-09-02 | move links from http to https://www.openbsd.org/ | Theo Buehler | |
| ok beck | |||
| 2016-06-07 | per trending style, add continue to empty loops. | Ted Unangst | |
| ok mglocker | |||
| 2016-05-21 | <sys/localedef.h> isn't needed for ddb structinfo | Philip Guenther | |
| ok millert@ deraadt@ schwarze@ | |||
| 2016-04-20 | Collapse db_dwarf.h into db_sym.h | Martin Pieuchot | |
| ok matthew@ | |||
| 2016-04-19 | Do not expose private functions. | Martin Pieuchot | |
| 2016-04-19 | Start reducing the dependence on <uvm/uvm_param.h> by using int-1-0 | Martin Pieuchot | |
| instead of boolean_t-TRUE-FALSE. | |||
| 2016-04-19 | Keep db_write_cmd() in the only place where it is used, just like we did | Martin Pieuchot | |
| with db_show_regs(). | |||
| 2016-03-09 | Move db_show_regs() in the only file where it is used and turn it private. | Martin Pieuchot | |
| ok mlarkin@ | |||
| 2016-03-07 | Sync no-argument function declaration and definition by adding (void). | Christian Weisgerber | |
| ok mpi@ millert@ | |||
| 2016-03-07 | boolean_t/FALSE/TRUE -> int/0/1 | Martin Pieuchot | |
| 2016-03-06 | Merge db_elf_sym_values() into db_symbol_values(). | Martin Pieuchot | |
| ok stefan@ | |||
| 2016-03-06 | DDB_REGS -> &ddb_regs. | Martin Pieuchot | |
| All our archs use the same define. | |||
| 2016-03-01 | db_sym_numargs() has always been defined to FALSE so nuke it with all | Martin Pieuchot | |
| its associated dead code. ok mikeb@ | |||
| 2016-03-01 | Make db_value_of_name() call db_elf_sym_lookup() in order to kill | Martin Pieuchot | |
| db_lookup() as requested by mlarkin@ While here move the function to db_elf.c do keep db_elf_sym_lookup() private. ok mikeb@ appart from the move the function | |||
| 2016-03-01 | DB_SYM_NULL -> NULL. | Martin Pieuchot | |
| 2016-02-28 | Remove leftovers from mutliple symbol tables support. | Martin Pieuchot | |
| 2016-02-27 | Remove the "symbol table" argument of the functions dealing with | Martin Pieuchot | |
| symbols. There's no reason to ask the programmer to supply a specific symbol table since the kernel only have one. ok visa@, guenther@ | |||
| 2016-02-26 | Remove support for multiple symbol tables in ddb(4), we only have one. | Martin Pieuchot | |
| ok mlarkin@, visa@ | |||
| 2016-02-12 | Kill db_symbol_is_ambiguous(). There's no ambiguous symbol since LKMs | Martin Pieuchot | |
| are no longer supported. ok tb@, guenther@ | |||
| 2016-01-27 | Removes the abstraction layer to support multiple executable binaries. | Martin Pieuchot | |
| Simplifies the API to manipulate symbols now that all our architectures are ELF. ok tb@ | |||
| 2016-01-27 | Remove unused db_sifting(). | Martin Pieuchot | |
| 2016-01-25 | Do not mix variable declaration and logic. | Martin Pieuchot | |
| 2016-01-25 | Kill "#if 0" version of ddb_init(). | Martin Pieuchot | |
| 2016-01-25 | Kill trailing whitespaces. No object change. | Martin Pieuchot | |
| 2016-01-15 | add a "show socket" command to ddb | David Gwynne | |
| should help inspecting socket issues in the future. enthusiasm from mpi@ bluhm@ deraadt@ | |||
| 2015-12-23 | assign pointers NULL rather than 0 | mmcc | |
| 2015-09-13 | On show the ps/o output and ddb.html blurb once, so that we don't get them | Philip Guenther | |
| after each "mach ddbcpu N" ok miod@ deraadt@ | |||
| 2015-09-12 | show a few more lines of trace; discussed in the room | Theo de Raadt | |
| 2015-09-12 | When panicing, show the non-idle, on-proc threads before showing the stack | Philip Guenther | |
| trace ok deraadt@ miod@ beck@ | |||
| 2015-09-01 | initialise the width var in db_struct_offset_cmd() | Jonathan Gray | |
| ok miod@ deraadt@ | |||
| 2015-08-30 | Automatically perform traces upon panic. Shrink message about | Theo de Raadt | |
| reporting bugs to pointing at http://www.openbsd.org/ddb.html, because vertical space becomes more precious. ok beck krw kettenis | |||
| 2015-08-12 | Use a linker script when building i386 kernels to allow section padding on | Mike Larkin | |
| PAGE_SIZE boundaries. This is required to enforce proper separation of sections when adding page protections (coming shortly). This was in snaps before release with no reported side effects. ok deraadt@ | |||
| 2015-07-07 | Return correct file name entry from DWARF line table | Matthew Dempsky | |
| We run the DWARF line table program to generate each row of the table until we find a row after the one we wanted, and then take the previous row's entries. The code correctly took the previous row's line number entry, but incorrectly took the current row's file name entry. Notably, this caused DDB to report the wrong file names for inlined calls to functions defined in header files. ok mlarkin | |||
| 2015-05-05 | emul_native is only used for kernel threads which can't dump core, so | Philip Guenther | |
| delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump, and various #includes that are superfluous. This leaves compat_linux processes without a coredump callback. If that ability is desired, someone should update it to use coredump_elf32() and verify the results... ok kettenis@ | |||
| 2015-04-29 | Also generate db_structinfo.txt with struct member offset and size info | Philip Guenther | |
| prodded by deraadt@ and miod@ | |||
| 2015-03-14 | restore systm.h, needed for strcmp. from Steven McDonald | Ted Unangst | |
| 2015-03-14 | Remove some includes include-what-you-use claims don't | Jonathan Gray | |
| have any direct symbols used. Tested for indirect use by compiling amd64/i386/sparc64 kernels. ok tedu@ deraadt@ | |||
| 2015-01-27 | remove #include <sys/workq.h>. it wont exist anymore soon. | David Gwynne | |
| 2014-12-21 | Prevent writing to the kernel area via the direct map. We do this by padding | Mike Larkin | |
| the end of the kernel area to 2MB, so that the direct map pages can then have the W permission removed (X permission was already removed in a previous diff). This creates a VA hole at the end of bss, so adjust for that since that's where symbols get loaded by the bootloader (for now, map that region RO until the boot loader can be updated to place the symbols at "end" instead of "end of bss"). with help from and ok deraadt@ | |||
| 2014-12-19 | Use <sys/endian.h> instead of <machine/endian.h> | Philip Guenther | |
