a382cafacc fix "Non-matching signing type" 2021-01-17 19:33:53 -05:00

1e9500c97e Define the filename for ed25519 keys, instead of using the default 
/etc/dropbear path (which won't work on Android).

fd81eb7897 Remove #ifndef guards around host key filenames because they are 
essential #defines.  I think they just were there from an ancient cut and
paste?

ecf6efb562 After a warning audit, fix the one warning that is my fault. The other 
warnings all come from dropbear being sloppy about char* vs unsigned char*.
I've got a variety of opinions about what should be done about it but I'm
not going to interfere with it because they'll surely fix it upstream
sooner or later.

62dcaa750a Enable GCM, too. I'm not clear on what it is but default_options.h says 
it should be enabled for compatibility if you can spare 6kB of executable
size.  Anyways, it's new.

d59d79da18 Enable ed25519, which is the main attraction for dropbear 2020.81. 2020-12-28 23:21:45 -05:00

c066139c3a Now need a dropbear config #define to use the built-in libtom. 2020-12-28 22:59:03 -05:00

fb7eab1fe9 Disable Blowfish, which is no longer supported by dropbear (but they 
failed to completely remove it, so it causes a compilation error if
enabled instead of being ignored).

903bfa7ca2 Merge branch 'dropbear' 
This time, to remove files that should have gone away (they are still
referenced in the build scripts, probably).

883d40f758 Whoops, the previous commit failed to take into account files that were 
(should have been) deleted as part of the dropbear 2020.81 update.
Delete them now.

4f0a0c7e8e Remaining conflicts are more straightforward. Preserve both my hack and 
dropbear's new behavior (as a fallabck) for when renaming a file using
hardlinks fails.  Either one alone would probably suffice but I know the
rename() hack works.

ec37382a5c Preserve the commit 60fcaa6 hack even though the hack it's embedded 
within was deemed unworthy by dropbear maintainers.

5f12050fde Merge branch 'dropbear' 
Update to dropbear-2020.81.
Does not build.  I did not even resolve the merge conflicts because the
first one I looked at wasn't entirely trivial.

71dcbc392b Normalize the dump code a little bit, and expand to 128 stack entries 
just in case the problem is still there.

getnameinfo() doesn't work (Android 16).

bb8753a5a6 Disable DROPBEAR_SVR_MULTIUSER, because we don't want to be calling 
setuid/seteuid sort of stuff (it won't work, and I think sec-comp or
something kills our process).  Also need to disable the sanity check.

5a5cc34841 Use correct #define to disable using environment variable to supply 
password (not that it matters, since we don't build the db client).

43cd46fd0d su is not a login shell, so if it's in the shell's filename, don't put 
"-" before argv[0], but do put it in argv[1] because su accepts it as a
regular parameter ("-su" was breaking busybox)

651ba21816 don't call pty_release() because it always fails, and because we never 
pty_setowner()ed in the first place.  never noticed it before because
it's only called if the shell command fails (apparently)

60fcaa6ec9 When reading data from various spots in /proc to initialize the random 
number generator:
 * reduce timeout from 2s to 1ms
 * if timeout, abort
 * only read first 4096 bytes
this is to work around the fact that on Samsung Tab 4, /proc/timer_list
is apparently 167MB!

f74a71fdd4 cast away the const on DROPBEAR_PIDFILE to get rid of the last warning.

2eb8fa9355 don't clear the environment when spawning shells, so that android system
