659852acd5 libs/libc/unistd/lib_getopt.c: Add logic to reinitialize the stale context for the FLAT/PROTECTED builds. In these builds getopt() global varriables may be shared by many tasks. If any task exits the getopt() loop before all command line arguments have been parsed, then getopt() global variables will be left in a bad state. The next time getopt() is called, this logic should detect the bad state and force the state of getopt() to be re-initialized so that it can be reused. This logic is not full proof (it would fail, for example, if you tried to parse the same command line twice) but should catch the typical misuse cases. 2019-02-05 10:30:59 -06:00

a77c073797 arch/: Fix an interlock that was broken by commit 641a98a434 in all implementations of up_sigdeliver. 2019-02-03 17:14:32 -06:00
Gregory Nutt
641a98a434 arch/: The saved return register state is available on the user stack. Thic commit reorders some logic so that certain, critical registers are preserved in the TCB. This does not make the logic 100% secure, but does prevent some obvious things. sched/signal/sig_delivery: Add a flag to the TCB to indicate that we are in a signal handler. Use this flag to assure that a there a never attempts to nest signal handling operations on a thread. This was guaranteed before but when locking of pre-emption during signal delivering was eliminated in a previous commit, there was a remote possibility of an attempt to do nested signal handling. This flag assures that there is only one signal handled at a time. 2019-02-03 15:29:47 -06:00

71e6793702 sched/sched: Rename all internal, static functions from sched_* to nxsched_* to indicate that they are NuttX internal functions. This is only a start. Eventually, need to rename all sched_ functions prototyped in sched/sched/sched.h and in include/nuttx with nxsched_. 2019-02-03 14:18:39 -06:00

d8943be51c arch/arm/src/sam34 and sama5: Port Anthony Merlino's fix of commit ee840c74da to similar Ethernet drivers for parts in other SAM families. 2019-02-02 16:14:43 -06:00

ee840c74da Merged in antmerlino/nuttx/samv7_emac_bna_fix (pull request #824) 
arch/arm/src/samv7/sam_emac.c: Fixes rxdesc index logic to handle Buffer Not Available (BNA) condition.

If a SOF is found, but no EOF, don't move past the frame. Instead, keep the index at the SOF buffer until the rest of the data is written.

This fixes a receiver lockup condition where the peripheral and this driver get out of sync with there head pointers. In this case the driver has moved past buffers it owns, without clearing ownership, which results in the peripheral and driver in a deadlock with each other.

5bf7890d32 arch/arm/src/lpc17xx/lpc17_allocateheap.c: Correct some confusion in the memory layout introduced in commit 40d666f440. The 'primary ram' may be either the internal SRAM or the external DRAM (in the case where an external bootloader has previously initialized the SDRAM). The primary ram is laid out as: .data, .bss, then the IDLE stack allocation. The global variable g_idlestack is the top of the IDLE stack and also the beginning of memory available for the heap in primary ram. With this change, a range comparison is used to determin if g_idlestack lies in SRAM or SDRAM. If so, then the remainder of the memory is available for HEAP usage. 2019-01-28 06:08:30 -06:00
