* Add support for encrypted kernel crash dumps.Konrad Witaszczyk2016-12-109-25/+812
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes include modifications in kernel crash dump routines, dumpon(8) and savecore(8). A new tool called decryptcore(8) was added. A new DIOCSKERNELDUMP I/O control was added to send a kernel crash dump configuration in the diocskerneldump_arg structure to the kernel. The old DIOCSKERNELDUMP I/O control was renamed to DIOCSKERNELDUMP_FREEBSD11 for backward ABI compatibility. dumpon(8) generates an one-time random symmetric key and encrypts it using an RSA public key in capability mode. Currently only AES-256-CBC is supported but 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 this automatically during startup using the dumppubkey rc.conf(5) variable. Once the keys are calculated dumpon sends them to the kernel via DIOCSKERNELDUMP I/O control. When the kernel receives the DIOCSKERNELDUMP I/O control it generates a random IV and sets up the key schedule for the specified algorithm. Each time the kernel tries to write a crash dump to the dump device, the IV is replaced by a SHA-256 hash of the previous value. This is intended to make a possible differential cryptanalysis harder since it is possible to write multiple crash dumps without reboot by repeating the following commands: # sysctl debug.kdb.enter=1 db> call doadump(0) db> continue # savecore A kernel dump key consists of an algorithm identifier, an IV and an encrypted symmetric 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 to make 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 the kernel dump key is placed after the first header on the dump device and the core dump is encrypted. Separate functions were implemented to write the kernel dump header and the kernel dump key as they need to be unencrypted. The dump_write function encrypts data if the kernel was compiled with the EKCD option. Encrypted kernel textdumps are not supported due to the way they are constructed which makes it impossible to use the CBC mode for encryption. It should be also noted that textdumps don't contain sensitive data by design as a user decides what information should be dumped. savecore(8) writes the kernel dump key to a key.# file if its size in the header is nonzero. # is the number of the current core dump. decryptcore(8) decrypts the core dump using a private RSA key and the kernel dump key. This is performed by a child process in capability mode. If the decryption was not successful the parent process removes a partially decrypted 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 run FreeBSD due to the problems with QEMU emulation and lack of hardware.

Failure to parse the directives results in a reboot right after the cleanup. Otherwise the boot sequence proceeds as usual. zfsbootcfg writes zfsboot arguments specified on its command line to the Pad2 area of a disk identified by vfs.zfs.boot.primary_pool and vfs.zfs.boot.primary_vdev kenv variables that are set by loader during boot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In r307684, I changed rescan_or_reset_bus() to bzero stack-allocated CCBs before sending them to the kernel because there was stack garbage in there that wound up meaning that bogus CCB flags were set. While this fixed the 'camcontrol rescan all' case (XPT_DEV_MATCH CCBs were failing previously), it broke the 'camcontrol rescan 0' (or any other number) case when INVARIANTS are turned on. Rescanning a single bus reliably produced an assert in cam_periph_runccb(): panic: cam_periph_runccb: ccb=0xfffff80044ffe000, func_code=0x708, flags=0xffffdde0 The flags values don't make sense from the code. Changing the CCBs in rescan_or_reset_bus() from stack to heap allocated avoids the problem. It would be better to understand why userland stack allocated CCBs don't work properly, since there may be other code that breaks if stack allocated CCBs don't work. sbin/camcontrol/camcontrol.c: In rescan_or_reset_bus(), allocate the CCBs using malloc(3) instead of on the stack to avoid an assertion in cam_periph_runccb().
