Sometimes, when adding a PIN to a keyring (eg, when opening a keyring
file), a SEGV would be caused while trying to validate the MAC for an
entry which apparently had zero keypair entries.
Changed some keyring struct 'int' fields to 'unsigned int', to ensure
that comparison logic behaves as expected.
Refactored some keyring code for more clarity and code maintenance
safety.
Added TODO comment about keyring file format non-back-compatibility.
OUT()s or where return() is used instead of RETURN().
Added OUT() to end of all functions using IN() that lacked it to
make it easier to statically analyse this invariant.
Fixed several return instead of RETURNs detected through use of
this tool. #49
Output is same format as "keyring add" command
Fixed minor bug in rolling a random DID -- last byte was not random
Some code improvements, including better support for sid_t
Replace explicit [<pin,pin...>] command-line arguments with --entry-pin=<pin>
options. Update test scripts accordlingly.
Add --keyring-pin=<pin> option (with one test case).
Move lots of non-Serval-specific string functions from "serval.h"/dataformats.c
to "str.h"/str.c.
Add str_fromprint() function that reverses the effect of toprint(): interprets
escape sequences in the source string "\n\t\r\0\xHH\\" and replaces them with a
single char in the destination string.
type on next use (so that people upgrading automatically get a new valid
SAS instead of continuing to try to use an invalid one -- this is only
a reasonable course of action since we have made no formal releases of
the code). #17
as recommended a while back by Dan Bernstein as offering the fastest
implementation of the crypto_sign() primitives for ARM.
Indeed this implementation IS faster. See comparison below for a
Rock 500 handset (800MHz(?) ARM6, no NEON):
Original ref/ implementation on an R500 stock rom (non-rooted)::
mean signature generation time = 96.80ms
mean signature verification time = 272.20ms
ref10/ implementations on an R500 stock rom (non-rooted):
mean signature generation time = 4.00ms
mean signature verification time = 13.00ms
Approximately 20x speed up, just like that :)
