fs/vfs:null check for path on open and buf on write

Null path check is depend on CONFIG_DEBUG_FEATURES and CONFIG_DEBUG_ASSERTIONS, added null checking so it's always performed
Added null checking on buf for write()

ae78a925eb Add support for an in-memory routing table cache in order to improve performance when the routing table is retained in a file. The cache holds the most recently used routing table entries and so can eliminate some file access.
Squashed commit of the following:

    net/route:  Flush in cache when any entry is deleted from the routing table.  When a router matching an IP address is found, add the routing table entry to the cache.

    net/route:  Add utility functions to manage an in-memory cache to improve performance when use a file-based routing table.

44d88abb83 This commit adds support for routing tables in files in a file system. This might be useful for customized, per-unit routing tables.
There are two issues with it however:

1. Reading from file system on a per packet basis could be slow.  I think it probably should have a small, in-memory cache of most frequently used routes for good problem.

2. Currently the delroute logic is disabled due to a problem with the design.  NuttX does not currently support truncate().  Therefore, it is not possible to delete entries from the routing table file.

In this current implementation, that leaves the last entry intact at the end of the file.  An alternative design might include a tag on each record to indicate if the record is valid or not.  That would work but would add complexity to the other routing table functions.

The existing implementation is available for testing purposes only if CONFIG_EXPERIMENTAL=y.

Squashed commit of the following:

    net/route:  The current delroute design depends on file truncation.  However, NuttX does not currently support truncate.  Alternative, more complex designs are possible but not implemented.  At present the file routing table are otherwise functional but the delroute logic is disabled via CONFIG_EXPERIMENTAL.  Enable it only if you plan to fix it.

    net/route:  Fix some issues with locking routing table files.

    net/route:  Add partial implementation of delroute for the case where the routing table is in a file.

    net/route:  Add support for seeking to positions in the routing table.

    net/route: Add net_addroute_ipv4/6() using a file-based routing table.

    net/route: Add net_foreach_ipv4/4() using a file-based routing table.

    net/route:  Initial build, configuration, and fs utilies to support routing tables in a file.

STM32L4 FLASH, DFSDM: option bytes, JEXTSEL bits, ADC1 output to DFSDM chips change

* STM32L4 FLASH: add function for modifying device option bytes

* STM32L4 DFSDM: add JEXTSEL bits, ADC1 output to DFSDM chips change

    ST's documentation hints that ADC output can be routed to DFSDM
    on some STM32L4X3 chips, but I got confirmation from tech support
    that this is just a documentation error so remove this from Kconfig.

3aa18ef56e Addes support for read-only routing tables. Prior to this change, routing tables were only support in RAM and had to be initialized with explicit logic to add the necessary routes to the routing table. With this change, routes may be defined in the pre-initialized, read-only routing table provided by the board-specific logic
This would be particularly useful, for example, in the case where there is only a single network adaptor and you want all output packets to go to the single adaptor in all cases.  So for that behavior you could add a read-only routing table to the board-specific long that contains a single entry, the default route: 0.0.0.0/0.

Squashed commit of the following:

    net/route:  RAM and ROM routing tables build correctly in all IPv4 and IPv6 configurations.

    net/route: Verify IPv6 ROM route build; Make number of ROM routes a variable, not a configuration item.

    net/route:  Add initial support for ROM-base, read-only routing tables.

    net/route:  Adjust and generalize some structures, rename some functions, and add configuration and build support that will eventually support read-only routing tables.

    net/route:  Some initial though experiments on use of a fixe, read-only routing table

4e3c159145 drivers/usbdev/cdcacm.c: Add a failsafe time to assure that the RX pending queue cannot stall indefinitely. I can imagine a corner case where the serial driver's RX buffer is full and it stops accepting data and where all of the read requests are queued and there is not event to restart RX processing. I am not sure that that scenario can really happen, but the failsafe timer gives me peace of mind. 2017-09-26 09:30:54 -06:00

Subject: [PATCH] ICMPv6: fix router advertisement

Fixes several errors preventing icmpv6_radvertise.c from being compiled. Fixes conversions to network byte order (namely vlifetime, plifetime, mtu).

IPv6 source address is set to link-local IP address instead of the address in the netdev structure. This is in compliance to RFC 4861. RA didn't work on Linux before this change.

Finally, router prefix and prefix length are derived from the IPv6 address and netmask in the netdev structure. This seems to make more sense than using a predefined, separate prefix from the config.
