A new tool called decryptcore(8) was added.A new DIOCSKERNELDUMP I/O control was added to send a kernel crash dumpconfiguration in the diocskerneldump_arg structure to the kernel.The old DIOCSKERNELDUMP I/O control was renamed to DIOCSKERNELDUMP_FREEBSD11 forbackward ABI compatibility.dumpon(8) generates an one-time random symmetric key and encrypts it usingan RSA public key in capability mode. Currently only AES-256-CBC is supportedbut EKCD was designed to implement support for other algorithms in the future.The public key is chosen using the -k flag. The dumpon rc(8) script can do thisautomatically during startup using the dumppubkey rc.conf(5) variable. Once thekeys are calculated dumpon sends them to the kernel via DIOCSKERNELDUMP I/Ocontrol.When the kernel receives the DIOCSKERNELDUMP I/O control it generates a randomIV and sets up the key schedule for the specified algorithm. Each time thekernel tries to write a crash dump to the dump device, the IV is replaced bya SHA-256 hash of the previous value. This is intended to make a possibledifferential cryptanalysis harder since it is possible to write multiple crashdumps without reboot by repeating the following commands:# sysctl debug.kdb.enter=1db> call doadump(0)db> continue# savecoreA kernel dump key consists of an algorithm identifier, an IV and an encryptedsymmetric key. The kernel dump key size is included in a kernel dump header.The size is an unsigned 32-bit integer and it is aligned to a block size.The header structure has 512 bytes to match the block size so it was required tomake a panic string 4 bytes shorter to add a new field to the header structure.If the kernel dump key size in the header is nonzero it is assumed that thekernel dump key is placed after the first header on the dump device and the coredump is encrypted.Separate functions were implemented to write the kernel dump header and thekernel dump key as they need to be unencrypted. The dump_write function encryptsdata if the kernel was compiled with the EKCD option. Encrypted kernel textdumpsare not supported due to the way they are constructed which makes it impossibleto use the CBC mode for encryption. It should be also noted that textdumps don'tcontain sensitive data by design as a user decides what information should bedumped.savecore(8) writes the kernel dump key to a key.# file if its size in the headeris nonzero. # is the number of the current core dump.decryptcore(8) decrypts the core dump using a private RSA key and the kerneldump key. This is performed by a child process in capability mode.If the decryption was not successful the parent process removes a partiallydecrypted core dump.Description on how to encrypt crash dumps was added to the decryptcore(8),dumpon(8), rc.conf(5) and savecore(8) manual pages.EKCD was tested on amd64 using bhyve and i386, mipsel and sparc64 using QEMU.The feature still has to be tested on arm and arm64 as it wasn't possible to runFreeBSD due to the problems with QEMU emulation and lack of hardware.Designed by: def, pjdReviewed by: cem, oshogbo, pjdPartial review: delphij, emaste, jhb, kibApproved by: pjd (mentor)Differential Revision: https://reviews.freebsd.org/D4712 List of files: /freebsd/sbin/dumpon/Makefile Sat, 10 Dec 2016 17:20:39 +0100 Konrad Witaszczyk <def@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sbin/dumpon/Makefile#13caa468668019a6c93ed6ff65ab21c673b378cb Merge the projects/release-pkg branch to head.This allows packaging the base system with pkg(8), includingbut not limited to providing the ability to provide upstreambinary update possibilities for non-tier-1 architectures.This merge is a requirement of the 11.0-RELEASE, and as such,thank you to everyone that has tested the project branch.Documentation in build(7) etc. is still somewhat sparse, butupdates to those parts will follow.Sponsored by: The FreeBSD Foundation List of files: /freebsd/sbin/dumpon/Makefile Sat, 16 Apr 2016 09:45:30 +0200 Glen Barber <gjb@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sbin/dumpon/Makefile#406d87b1c3c9fb02dc1256f4e634c0fc71a22799 Explicitly add more files to the 'runtime' package.Sponsored by: The FreeBSD Foundation List of files: /freebsd/sbin/dumpon/Makefile Tue, 09 Feb 2016 21:19:31 +0100 Glen Barber <gjb@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sbin/dumpon/Makefile#1a0fda2b547365c9453523592a445dfe21266d4b IFH@204581 List of files: /freebsd/sbin/dumpon/Makefile Thu, 04 Mar 2010 14:35:57 +0100 Dag-Erling Smørgrav <des@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sbin/dumpon/Makefile#874108aed99d76099ff9eb6c8d830479a504c1ad MFC @199204 List of files: /freebsd/sbin/dumpon/Makefile Thu, 12 Nov 2009 01:36:22 +0100 Oleksandr Tymoshenko <gonzo@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sbin/dumpon/Makefile#106d839190bf604806e084ce5e7dd8ee8142c1d9 Switch the default WARNS level for sbin/ to 6.Submitted by: Ulrich Spörlein List of files: /freebsd/sbin/dumpon/Makefile Mon, 19 Oct 2009 18:00:24 +0200 Ruslan Ermilov <ru@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sbin/dumpon/Makefile#9f4ed0f59bdcc8ddf5018ec2bfbd91c5eb774348 dumpon builds cleanly at WARNS level 6.

When "off" is set, /dev/null is used.
