+ *  COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or
+ *  code or tables extracted from it, as desired without restriction.
+ *
+ *  First, the polynomial itself and its table of feedback terms.  The
+ *  polynomial is
+ *  X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ *  Note that we take it "backwards" and put the highest-order term in
+ *  the lowest-order bit.  The X^32 term is "implied"; the LSB is the
+ *  X^31 term, etc.  The X^0 term (usually shown as "+1") results in
+ *  the MSB being 1
+ *
+ *  Note that the usual hardware shift register implementation, which
+ *  is what we're using (we're merely optimizing it by doing eight-bit
+ *  chunks at a time) shifts bits into the lowest-order term.  In our
+ *  implementation, that means shifting towards the right.  Why do we
+ *  do it this way?  Because the calculated CRC must be transmitted in
+ *  order from highest-order term to lowest-order term.  UARTs transmit
+ *  characters in order from LSB to MSB.  By storing the CRC this way
+ *  we hand it to the UART in the order low-byte to high-byte; the UART
+ *  sends each low-bit to hight-bit; and the result is transmission bit
+ *  by bit from highest- to lowest-order term without requiring any bit
+ *  shuffling on our part.  Reception works similarly
+ *
+ *  The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ *      The table can be generated at runtime if desired; code to do so
+ *      is shown later.  It might not be obvious, but the feedback
+ *      terms simply represent the results of eight shift/xor opera
+ *      tions for all combinations of data and CRC register values
+ *
+ *      The values must be right-shifted by eight bits by the "updcrc
+ *      logic; the shift must be unsigned (bring in zeroes).  On some
+ *      hardware you could probably optimize the shift in assembler by
+ *      using byte-swap instructions
+ *      polynomial $edb88320

+Subject: [PATCH] file: Check buffer size after strtok()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This fixes a heap overflow in the parsing of the uci line.
+
+The line which is parsed and put into pctx->buf is null terminated and
+stored on the heap. In the uci_parse_line() function we use strtok() to
+split this string in multiple parts after divided by a space or tab.
+strtok() replaces these characters with a NULL byte. If the next byte is
+NULL we assume that this NULL byte was added by strtok() and try to
+parse the string after this NULL byte. If this NULL byte was not added
+by strtok(), but by fgets() to mark the end of the string we would read
+over this end of the string in uninitialized memory and later over the
+allocated buffer.
+
+Fix this problem by storing how long the line we read was and check if
+we would read over the end of the string here.
+
+This also adds the input which detected this crash to the corpus of the
+fuzzer.

+define Package/$(PKG_NAME)/description
+  urngd is OpenWrt's micro non-physical true random number generator based on
+  timing jitter.
+
+  Using the Jitter RNG core, the rngd provides an entropy source that feeds into
+  the Linux /dev/random device if its entropy runs low. It updates the
+  /dev/random entropy estimator such that the newly provided entropy unblocks
+  /dev/random.
+
+  The seeding of /dev/random also ensures that /dev/urandom benefits from
+  entropy. Especially during boot time, when the entropy of Linux is low, the
+  Jitter RNGd provides a source of sufficient entropy.
