cotag read could enter endless loop, now cancels if the next bit doesn't
appear
em4x05 detection would loop due to a threshold never being met, now has
a dump out after 1000 samples tested.
fixed some indenting in hitag2 while i was reviewing that code for
potential endless loops...
* more timing fixes
* correctly determine correction bit (taken from iceman's fork)
* add checking of Access Conditions for Read command
* never allow reading KeyA
* move to separate files mifaresim.[ch]
* check CRC of commands
* don't execute commands without successfull authentication
* ensure correct timing of REQA, WUPA, ANTICOL and SELECT responses
* trace reader commands immediately, only fix start time after tag response. Decreases time to be ready for next reader command.
* remove iso14443-4 remnants
* trace raw reader commands instead of decrypted ones
* some refactoring
* fix hf mf sim
* timing: decrease time to get ready for new reader commands
Improve hf mf chk and hf mf nested
* hf mf chk. added interrupt of procedure by usb
* extract mifare default keys into separate module
* arm side multisector `hf mf chk`
* hf mf nested. change key search procedure
* hf mf nested. added key check after we have found a key.
* small fix hf list f
* hf mf chk. add timeout (arm side) and some tweaks.
* adjust LFSim to download lf fpga prior to setting emulation buffer to prevent buffer overwrite condition if you are coming from HF fpga.
* fix lf sim big buff overwrite with fpga download. Move fix to the buffer download cmd.
.. data for both format types (64 bit and 224 bit)
also adjust 224 bit demod and clone to output and input in PSK2 instead
of PSK1 as this appears to be most common for this format.
- Check button press when there is NOFIELD, so we can exit also without FIELD
- struct nonces_t is moved to include/mifare.h so client and arm has the same definition
... to speed up the loops waiting for carrier signal to go high or low
by only checking for a halt (button press or usbpol) every 1000th loop
iteration.
some users were experiencing modulating reactions to be too slow.
* Improve 'Magic' Mifare tags detection
* Magic Mifare tags detection and version printing
* Magic s50/1k tag halt error correction for cload and csave
* hf mf c* commands for gen1b
* Use |= for bitwise operation
* gen1b: don't issue wipe command and don't expect response from WUPC1 magic command after a SELECT_UID: old UID display works in hf mf csetuid
* hf mf cgetsc compatibility for 4k
* hf mf csave compatibility for 4k
* hf mf cload compatibility for 4k, suppress halt errors messages for debug level 2
* Revert to MF_DBG_ERROR level in mifare_classic_halt() and don't issue the halt command for gen1b
* Improve 'Magic' Mifare tags generation detection & hf mf c* commands magic 4k compatibility
endless loop in reader if no tag was found
button press on pm3 did not cancel.
led_b was left on in some cases
also moved 14b detection to last in hf search to help speed up the
command for the other tags. 14b is slow (does multiple tests)
Thanks to @Fl0-0 and @pwpiwi for their idenfication of some of the
issues.
memory locations in code are now accurate and the CC output is not
corrupted by the config's crc.
also the looping and flags for what to read are now correctly
implemented in the code.
