c6851201c0 This commit adds a new function arch_invalidate_dcache_by_addr(). It takes the same parameters as arch_invalidate_dcache(), but performs invalidation of only the lines in cache that need to be invalidated. This new function could be used as a a direct replacement for arch_invalidate_dcache().
The user of this invalidation are mmcsd_sdio currently.  The mmcsd_sdio driver makes calls for dcache invalidation through the chip specific architecture function SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache().

This commit includes additional changes to mmcsd_sdio.c.  I created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to invalidate store-into mode dcaches after the DMA transfer.  I have been using SDIO_DMADELYDINVLDT() for several weeks now and it has fixed the problems that I previously reported regarding non-cache aligned buffer invalidation errors (for my store-through dcache). However, it does not permit use of unaligned DMA buffers for store-into mode dcaches.

SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified all the stm32f7 chips to select it.

23aa2839c3 libs/libc/netdb/lib_dnsquery.c: harden against DNS spoofing. This commit implements most of the RFC 5452 guidelines for making DNS more resilient. We now verify response matches against what was queried and use unpredictable query IDs. It is also checked that response come from correct DNS server. Also fixes a buffer overflow when querying hostnames longer than CONFIG_NETDB_DNSCLIENT_NAMESIZE. 2018-11-16 06:56:45 -06:00

8a3fc26b74 Squashed commit of the following:
The MLD implementation did not follow the RFC correctly when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

    Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.

RNDIS composite support

* NuttX usb/composite.h: Forward-declare composite_devdesc_s.

    This avoids "error: conflicting types for 'composite_initialize'"
    on some versions of GCC. Because of the cross-inclusion between
    usbdev.h and composite.h, the full declaration is not always
    available.

* NuttX: USB Composite driver: Fix strid comparison

    The last string ID used by composite driver is 4, and
    the number of IDs used is 5 (0..4). The comparison
    strid <= COMPOSITE_NSTRIDS caused composite driver to
    reply with -EINVAL for id 5, even though it should be
    available for subdevices to use.

* NuttX: RNDIS USB driver: Add support for composite configuration.

a37c0c4cba NuttX: USB Composite and DFU drivers: Add support for Microsoft OS descriptors.
These Microsoft-only descriptors help in loading the correct driver on Windows.
They are especially helpful to give libusb access to a custom device without
having to manually configure/install WinUSB driver.

With this change DFU interface works automatically on
Windows 10 with dfu-util 0.9 and libusb 1.0.22. On Windows 7
it still appears to need driver installation.

5b7ef856a0 Squashed commit of the following:
net/mld:  The MLD logic now compiles and is much less toxic.  It still is not a proper MLD implementation:  (1) It is basically a port of IGMP, tweaked to work with IPv6 and ICMPv6 MLD messages, (2) it needs a proper analysis and comparison with RFC 3810, and (3) it is completely untested.  For this reason, it will remain EXPERIMENTAL for some time.

In the FLAT build, we must always set the errno and/or create cancellation points because the same library functions are used within the OS as are used by applications. This could cause issues for the OS but corrects some problems at the user interface.

ec498d2660 This commit brings in an inital port of the SPIFFS flash file system into NuttX. The file system is still untested at this point (and subject to some additional review). It is, however, marked EXPERIMENTAL should this should not cause a problem for anyone.
Squashed commit of the following:

    fs/spiffs:  Fix last compilation issue.  Now compiles without error.  It is still not quite ready for testing as there is additional code review that must be be performed.  It is now marked as EXPERIMENTAL so that it can be brought onto the master branch with little risk.

    fs/spiffs:  Remove some dead code.

    fs/spiffs:  Weak start of analysis of spiffs_nucleus.c.  Renamed to spiffs_core.c

    fs/spiffs:  Rename spiffs_nucleus.c to spiffs_core.c

    fs/spiffs:  Remove spiffs_config.h.  All configuration settings are now available in the SPIFFS Kconfig options.

    fs/spiffs:  Finished review, update, and repartitioning of spiffs_check.c.  Added spiffs_check.h.

    fs/spiffs:  Finished review, update, and repartitioning of spiffs_cache.c.  Added spiffs_cache.h.

    fs/spiffs:  Clean up some defines used in debug output statements.

    fs/spiffs:  Finished review, update, and repartitioning of spiffs_gc.c.  Added spiffs_gc.h.

    fs/spiffs:  Now that VFS interface is completed, I have begun the long march of repartitioning the remaining functionality, reviewing logic, identifying dead code, and cleaning up loose ends.

    fs/spiffs:  Initial integration of MTD interface, replacing the SPIFFS native flash interface.  Lots of open issues such as the use of pages vs. blocks vs. erase blocks and units of addresses, offsets, and lengths that are passed in function calls.  Remove SPIFFS_USE_MAGIC support.  That option (which default to OFF anyway), wrote a magic value at the beginning of every sector and support verifiable identification of the file system.  It was not being and used and removing it makes life simpler.

    fs/spiffs:  Remove semaphore lock on the file object structure.  Ultimately, the file access must modify the volume and access the volume structue which also has a exclusivity lock.  So use of the volume lock alone should be sufficient.

    Integrated the SPIFFS rename logic into the NuttX VFS.  Removed non-standard application calls or convert them to IOCTL commands.  These were converted to IOCTL commands:  (1) integrity check, (2) garbage collection, and (3) format flash.  These were removed:  (1) Integrity check callback.  These provided a lot of good information about the state of the file system, but such callbacks are not compatible with a POSIX compliant file system.  (2) Index maps.  The index maps were a performance improvement feature.  The user could provide the memory and request that a region of a a file use that memory for improved lookup performance when accessing parts of the file.  The fallback is the less performance lookup by traversing the FLASH memory.  (3) Removed the quick garbage collection interface (the code is still used internally).  Only the full garbage collection is available to the user application via IOCTL.

    configs/sim/spiffs:  A simulator configuration to use for testing SPIFFS.

    fs/spiffs:  Integrate SPIFFS logic into NuttX VFS bind() and unbind() methods.

    fs/mount/fs_mount.c:  Add SPIFFS to the list of drivers that require MTD vs block drivers.

    fs/spiffs:  Trivial changes, mostly from analysis of how to integrate the rename() VFS method.

    fs/spiffs:  Connect NuttX VFS unlink method to the SPIFFS_remove() function.  Lots of name-changing.

    fs/spiffs:  Remove non-standard errno support.  Remove bogus SPIFFS_LOCK() and SPIFFS_UNLOCK() macros.

    fs/spiffs:  Add NuttX VFS implementation for statfs() method.  Clean up some of the accumulating compilation problems.

    fs/spiffs:  Add stat(), truncate() methods.  Dummy out unsupport mkdir() and rmdir() methods.

    fs/spiffs:  Replace some of the custom error numbers with standard error numbers.

    fs/spiffs:  Hooks read(), write(), fstat(), ioctl(), opendir(), closedir(), rewindif(), and readdir() into the NuttX VFS.

    fs/spiffs:  Beginning the organization to work with the NuttX VFS.  Lots of things are get broken!

    fs/spiffs:  Add spiffs.c which will be the interface between SPIFFS and NuttX.  No very close at present, however.

    fs/spiffs:  Clean up some compile problems introduced by coding standard changes.

    fs/spiffs:  A little closer to NuttX coding standard.

    fs/spiffs:  Ran tools/indent.sh against all files.  Closer to NuttX coding standard, but needs a lot more effort to be fully compliant.

    fs/spiffs:  This commit brings in version 0.3.7 of Peter Anderson's SPIFFS.  The initial commit includes the core FS files (with some definitions destributed to their correct header files) and hooks into the build system.

0939fd479f include/sys/socket.h: Renumber the socket types. They must begin at 1, not zero. Socket type zero has a special meaning for some interfaces. For example, getaddrinfo() uses a socket type of zero to many any type of socket. The is no standard name for the any-type-socket, but macOS uses SOCK_UNSPEC. NuttX will do the same.

992b293122 Squashed commit of the following:
fs/driver and fs/mount:  Add mount() support for file systems that require MTD drivers (vs. block drivers).
    fs/drivers:  Add support for named MTD drivers in the psuedo file system.  This will, eventually, allow us to mount file systems that need MTD drivers without having to fake an intervening block driver.

dec7ecbd56 net/tcp/tcp_recvwindow.c: In order to receive data we must not only have IOBs available, but we must also have at least one IOB chain qentry available. Otherwise, we will advertise that we an buffer a lot of data when, in fact, we cannot. This is an expermental fix to a performance problem noted by Masayuki Ishikawa. 2018-09-22 09:33:29 -06:00

Pull request for mtd/progmem refactoring.

* mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks

    page is a unit for read/write operation.
    eraseblock is a unit for erase operation.
    up_progmem_npages is a little bit confusing because it returns number of
    erase blocks in flash memory. This patch changes up_progmem_npages to
    up_progmem_neraseblocks. There is no logical change.

many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

sched/wqueue/kwork_notifier.c:  Redesign some data structures.  struct works_s must appear at the beginning of the notifier entry structure.  That is because it contains the work queue indices.  This solves a harfault issue.

    net/tcp/tcp_netpoll.c:  tcp_iob_work() needs to free the allocated argument when it is finished.

    net/tcp/tcp_send_buffered.c:  Extend psock_tcp_cansend() so that it also requires that at least on IOB is also avaialble.

    mm/iob:  iob_navail() was returning the number of free IOB chain queue entries, not the number of free IOBs.  Completely misnamed.

    net/tcp/tcp_netpoll.c:  Add logic to receive notifications when IOBs are freed (Needs CONFIG_NET_TCP_WRITE_BUFFERS and CONFIG_IOB_NOTIFIER).  At present, does nothing because the logic in in psock_tcp_cansend() does not check for the availability of IOBs.  That will change.

9d3148406c Signals were not a good choice of IPC to implement the poll function for several reasons: In order to handle the asynchrnous poll-related event, a substantial amount of state information is needed. Signals are only capable of passing minimal amounts of data. There are also complexities with performing kernel space signal handlers in kernel space code that is better to avoid. So, instead of signals, the equivalent logic was converted to run via a callback that executes on the high-priority work queue.
Squashed commit of the following:

    Fix up some final compile isses.

    net/netdev:  Convert the network down notification logic to use the new wqueue-based notification factility.

    net/udp:  Convert the UDP readahead notification logic to use the new wqueue-based notification factility.

    net/tcp:  Convert the TCP readahead notification logic to use the new wqueue-based notification factility.

    mm/iob:  Convert the IOB notification logic to use the new wqueue-based notification factility.

    sched/wqueue:  Signals are not good IPCs to support the target poll functionality for several reasons including the amount of data that can be passed with a signal and in the fact that in protected and kernel modes, user threads executing signal handlers in protected, kernel memory is problematic.  Instead, convert the same logic to perform the notifications via function callback on the high priority work queue.
