84e6510de5 arch/arm/src/max326xx: Add the first, untested cut of an watchdog timer driver. 2018-11-20 17:13:35 -06:00
Bob Feretich
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.

bdb60ac2f7 arch/arm/src/stm32/stm32_adc.c: Very mysterious. Several configurations now fail to build stm32_adc.o. This chante avoids those build failures, yet I see no code changed in recent months that should affect this. Any insights anyone? 2018-11-20 12:29:37 -06:00

97b0235d77 s/dirent: Corrects a problem with opendir() noted by Petteri Aimonen in Bitbucket Issue 132: "opendir() fails for FAT filesystem with trailing slash in path":
I see the following behaviour on NuttX 7.26, where I have SD card mounted on /flash and a directory called "frm" on it:

opendir("/flash")  returns  (DIR *) 0x1000c580
opendir("/flash/") returns (DIR *) 0x1000c5d0
opendir("/flash/frm")  returns (DIR *) 0x1000c620
opendir("/flash/frm/")  returns (DIR *) 0x0

From POSIX specs for opendir(): "A pathname ... that ends with one or more trailing slashes shall be resolved as if a single dot character ( '.' ) were appended to the pathname."

So for mount points, opendir() works correctly, but for FAT32 filesystem it fails to open directory if the path has a trailing slash. I'm not quite sure how to cleanly fix this. Stripping the trailing slash in opendir() would require allocating a separate buffer, while fixing it in the FAT32 code seems somewhat complex due to the short/long filename logic.

It is not a big issue for me, I'm just going to fix it on the application side. But still a small portability and standards compliance issue.

NOTE: You would not see this problem if you call opendir() indirectly in NSH (like 'ls -R /') because NSH contains logic to remove trailing '/' characters from paths.

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

dbf01d12b7 Assertions: Identify the running task correctly when dumping task state information. It takes time to switch to the target task after g_readytorun has been modified. If panic/assert happen during this period, the dump will contain the incorrect and confusing information due to the difference between the real running task and the return value of this_task(). This change resolve this problem by adding g_running_task to track the real running task through the context switch. 2018-11-15 07:11:51 -06:00
