(crash found by afl-fuzz) py/runtime: Check that keys in dicts passed as ** args are strings. 2018-03-30T00:13:32+00:00 Damien George damien.p.george@gmail.com 2018-03-30T00:09:00+00:00 urn:sha1:32807881954f106b9735de74fe984062a0815b81 Prior to this patch the code would crash if a key in a ** dict was anything other than a str or qstr. This is because mp_setup_code_state() assumes that keys in kwargs are qstrs (for efficiency). Thanks to @jepler for finding the bug. py/objstr: Remove unnecessary check for positive splits variable. 2018-02-20T08:19:02+00:00 Damien George damien.p.george@gmail.com 2018-02-20T08:19:02+00:00 urn:sha1:8769049e935a89daa51883755457a083a5589d4e At this point in the code the variable "splits" is guaranteed to be positive due to the check for "splits == 0" above it. py/objstr: Protect against creating bytes(n) with n negative. 2018-02-19T05:25:30+00:00 Damien George damien.p.george@gmail.com 2018-02-19T05:25:30+00:00 urn:sha1:4e469085c192017c5244bbc115bac90f4bb667cb Prior to this patch uPy (on a 32-bit arch) would have severe issues when calling bytes(-1): such a call would call vstr_init_len(vstr, -1) which would then +1 on the len and call vstr_init(vstr, 0), which would then round this up and allocate a small amount of memory for the vstr. The bytes constructor would then attempt to zero out all this memory, thinking it had allocated 2^32-1 bytes. py/unicode: Clean up utf8 funcs and provide non-utf8 inline versions. 2018-02-14T07:19:22+00:00 Damien George damien.p.george@gmail.com 2018-02-14T07:19:22+00:00 urn:sha1:19aee9438a7a8cf8539536dab5147aedb6b16bb3 This patch provides inline versions of the utf8 helper functions for the case when unicode is disabled (MICROPY_PY_BUILTINS_STR_UNICODE set to 0). This saves code size. The unichar_charlen function is also renamed to utf8_charlen to match the other utf8 helper functions, and the signature of this function is adjusted for consistency (const char* -> const byte*, mp_uint_t -> size_t).
