Work queue: In a recent change for a problem noted by Pascal Speck, it was noted (again by Pascal Speck) that the cancellation of existing work and replacement with new work must be atomic. Thanks, Pascal.

work_queue() must cancel existing work prior to queuing new work, otherwise the work queue can become corrupted. Problem noted by Pascal Speck.

commit 797d4adf7d41068c671f0217d369b797b269de1a
Author: Stefan Kolb <Stefan.Kolb@avat.de>

We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.
The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).
The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.

libc/stdlib: Error Fix
...
1.Fix an error in mkstemp() the could result in an infinite loop.
2.Fix for wrong output in some cases.
For Example:
1) input: "FILEXX"
output: "FILE00" and repeats same output for further invocations of mkstemp().
But, the ouput has to be FILE01, FILE02, ...., FILEZZ.
2)input: "FILEXXXXXX"
output: "FILE100000", for next invocation "FILE200000" and so on
But it's good, if the ouput goes like FILE000001, FILE000002, ..., FILE000101, ...

Whoops -- that #include <cxxabi.h> wasn't supposed to sneak in there. If present, it may already define a __cxxabiv1::__guard that we could use, but that file comes from libstdc++, and I don't think the NuttX buildroot-based toolchain would have that, which is why we need libxx in the first place.

Add entropy pool and strong random number generator
...
Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output.
Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.
