8abd1ad101 Add 'configure' subcommand which for now only allows setting and removing
of the BOOT flag. It can be performed on both attached and detached
providers.

2bd4ade694 Before using byte offset for IV creation, covert it to little endian.
This way one will be able to use provider encrypted on eg. i386 on
eg. sparc64. This doesn't really buy us much today, because UFS isn't
endian agnostic.

We retain backward compatibility by setting G_ELI_FLAG_NATIVE_BYTE_ORDER
flag on devices with version number less than 2 and not converting the
offset.

f6829a059f Fix what looks like a typo: MODULE_DEPEND() takes module names,
not KLD file names; and GELI module's name is g_eli, not geom_eli.

15d6ee8de5 - Unbreak the build when geli is compiled into the kernel (on as module),

700e04d9b6 Revert previous change, as I fixed MD5(9). 2006-03-30 18:50:00 +00:00
Pawel Jakub Dawidek
8e88808915 md_hash field in g_eli_metadata structure is not 4 byte aligned, which
case panic on sparc64.

The problem is in MD5(9) implementation. The Encode() function takes
'unsigned char *output' as its first argument, which is then assigned to
'u_int32_t *op'. If the 'output' argument is not 4 byte aligned (and in
geli(8) case it is not), sparc64 machine will panic.

I don't know how to fix MD5(9) in a clean way, so I'm implementing a
work-around in geli(8).

geli_da0_keyfile0_name="/boot/keys/da0.key0"
geli_da0_keyfile1_load="YES"
geli_da0_keyfile1_type="da0:geli_keyfile1"
geli_da0_keyfile1_name="/boot/keys/da0.key1"
geli_da0_keyfile2_load="YES"
geli_da0_keyfile2_type="da0:geli_keyfile2"
geli_da0_keyfile2_name="/boot/keys/da0.key2"

geli_da1s3a_keyfile0_load="YES"
geli_da1s3a_keyfile0_type="da1s3a:geli_keyfile0"
geli_da1s3a_keyfile0_name="/boot/keys/da1s3a.key"

efd9ac0dfc Add a __packed keyword to g_eli_metadata struct definition, so
sizeof(struct g_eli_metadata) will return the exact number of bytes needed
for storing it on the disk.
Without this change GELI was unusable on amd64 (and probably other 64-bit
archs), because sizeof(struct g_eli_metadata) was greater than 512 bytes
and geli(8) was failing on assertion.
